    The invention relates to a device for anchoring an inflatable concentrator pad, which has a translucent inlet window for coupling in solar radiation and a concentrator pad into at least two cavities subdividing reflector foil for concentrating the solar radiation in an absorber, with a pivoting device for pivoting the concentrator. Cushion, in particular around its longitudinal axis and with an anchoring device for the pivoting device.
    Furthermore, the invention relates to a device for concentrating solar radiation in an absorber with an inflatable concentrator pad, which has a translucent entrance window for coupling in solar radiation and a reflector foil dividing the concentrator pad into at least two cavities for concentrating the Solar radiation in an absorber, and with a device for holding the inflatable concentrator pad.
    From WO 2012/145774 a generic device for the concentration of solar radiation in an absorber has been known ge. The device has an inflatable concentrator, which is formed by an elongated, substantially cylindrical tubular casing made of a plurality of film elements. The shell has at the top a transparent entrance window for the passage of solar radiation. Furthermore, a reflector film is provided, with which the cushion is divided into at least two separate pressure chambers. The reflector film has a mirror surface, with which the incoupled solar radiation is focused in the direction of an absorber. Anchoring equipment is provided for anchoring the concentrator. The anchoring scaffold has a Nachführungs¬system to track the pillow-shaped concentrator to the Sonnenlauf. The tracking system has a plurality of tracking rings enclosing the concentrator pad, which are rotatably mounted by means of rolling devices. The tracking rings are supported on bottom-side pedestal elements.
    In tests, it has been found that the tracking support rings resting on the floor are exposed during operation to high overturning torques, in particular due to wind loads. In order to withstand the stresses during operation, therefore, the tracking ring compensation had to be massively formed. Nevertheless, in the previous embodiment, a portion of the external loads could not be kept away from the tubular concentrator. As a result of external influences, deformation states of the concentrator were observed during operation. However, such deformations could shorten the life of the concentrator or cause damage. More importantly, however, the effects on the geometry of the curved reflector foil can lower the efficiency of the concentrator.
    The object of the present invention is therefore to alleviate or eliminate the disadvantages of the prior art. The invention is therefore particularly aimed at creating a structurally simple, stable and cost-effective device of the type mentioned in the introduction with which the absorption of external loads, in particular wind loads, is improved in order to further increase the efficiency of the concentrator.
    This object is achieved by a device for holding a concentrator pad having the features of claim 1 and a device for concentrating solar radiation having the features of claim 18. Preferred embodiments are given in the dependent claims.
    According to the invention, the anchoring device has a suspension device for suspending the pivoting device.
    Unlike the prior art, therefore, the concentrator cushion pivoting and holding device is no longer supported on the bottom from the bottom, but is suspended from the top of a suspension device. Accordingly, the pivot device, to which the concentrator cushion is fastened in the operating state, is essentially completely supported by the suspension device. The pivoting or rotating device is arranged for pivoting the concentrator pad, which is composed of flexible (plastic) film elements, preferably about its longitudinal axis. For the purpose of this disclosure, the suspension of the pivoting device indicates that the fastening points between the suspension device and the pivoting device are arranged exclusively above a plane having the center of mass of the pivoting device. The terms "top" and "below" refer here to the Be¬triebsstellung the device. In particular, the invention has the advantage that the external loads, such as wind forces, can be collected in a particularly efficient manner and can be detached to a foundation at the site. It is particularly advantageous that the kis- sen- or tubular concentrator is kept largely free of äuße¬ren influences. As a result, the concave curvature of the reflector film between the upper and the lower pressure chamber of the preferably concentric cylindrical cross-section concentrator can be precisely maintained, so that the focusing of the solar radiation at the absorber is carried out with high efficiency. Furthermore, the embodiment according to the invention is advantageous in that the pivoting device can be made slimmer than in the prior art. Thus material costs can be saved. Furthermore, the degree of shading of the reflector film is reduced, whereby the efficiency can be further increased.
    For suspending the pivoting device for the concentrator cushion, it is expedient for the suspension device to have at least one carrier frame, preferably a plurality of carrier frames spaced apart in the longitudinal direction of the concentrator cushion, the at least one carrier frame each having at least one first frame element on one longitudinal side of the concentrator pad and a second frame member on the other longitudinal side of the concentrator pad. Accordingly, the first frame member and the second frame member are on the opposite longitudinal sides of the concentrator pad, i. laterally next to the concentrator cushion. The first frame member has a first attachment location for the pivot on one longitudinal side of the concentrator pad, the second frame member having a second attachment location for the pivot on the other longitudinal side of the concentrator pad. The fastening points of the frame element are arranged above the center of mass of the pivoting device. On the underside of the concentrator no support devices are provided, so that the pivoting device is suspended exclusively on the frame elements. Accordingly, the weight of the pivoting device, in the mounted state, the weight of the other components, such as concentrator pads, absorber suspension and absorber, is substantially completely supported by the support frame. Preferably, a plurality of such support frames are provided, the frame elements are arranged in particular at regular intervals laterally adjacent to the concentrator pad. The designation "long side " hereby refers to the fact that the concentrator pad has an elongated shape with two longitudinal sides. In addition, the concentrator pad at the front and rear end each have an end piece, with which the air-filled hollow or pressure chambers are sealed airtight in the main. Advantageously, the support frame can be produced very well from standard profiles, which leads to considerable cost advantages even with small quantities.
    In order to increase the stability of the suspension device, it is advantageous if the support frame has a third frame element above the concentrator pad, which surrounds the first frame element on one longitudinal side of the concentrator pad with the second frame element on the other longitudinal side of the con ¬zentrator pillow connects. In this embodiment, therefore, the support frame extends from the one longitudinal side of the Kon¬zentrator-pad over the top of the concentrator padhinweg on the other longitudinal side of the concentrator pad, so that the concentrator cushion is completely arranged in the assembled operating state within the support frame. The pivoting device is preferably suspended on the underside of the support frame. Thus, preferably, the pivot means is substantially completely framed by the support frame. This embodiment has proven to be particularly favorable for absorbing the forces occurring during operation, for example wind forces.
    The manufacturing costs can be reduced if the first frame element and / or the second frame element is composed of at least a first straight frame part and a second straight frame part, which are arranged at an angle to one another. The second frame part therefore connects at ei¬nem angle to the first frame part. The second is preferred
    Thus, the support frame extends close to the cross-section round concentrator pad, thereby increasing the stability of the assembly. Preferably, the third frame element is rectilinear, wherein the third frame member extends insbeson¬dere in a substantially horizontal plane above the pivoting means with the concentrator cushion.
    In order to anchor the concentrator to the ground, it is favorable if the first frame part is arranged substantially vertically in the operating state, wherein the first frame part is anchored at the lower end in a base element on the ground of the location.
    Preferably, the first frame member and / or the second Rah¬menelement and / or the third frame member as profile elements, in particular as I-profiles, formed, which are in a plane substantially perpendicular to the longitudinal direction of the concentrator pad. The profile elements have the same cross-section in the direction of their longitudinal extent. Such Profil¬elemente are known in construction in various designs, spielsweise with I-shaped cross-section. As a result, the manufacturing costs can be kept low.
    According to a particularly preferred embodiment, the suspension device has at least two support frames, which are connected to one another by means of a tensioning element, in particular a cable element. In particular, this embodiment has the advantage that the individual support frames can be made slender, yet a high stability of the arrangement is achieved by the tension between the support frames. Hereby it is also advantageous that the support frames made of profile elements do not cause significant shading of the support Concentrator cushion cause, which would lower the efficiency of the concentrator. Advantageously, this embodiment of the suspension device offers only low resistance to wind forces, which can prevent damage to the installation.
    The support frames are preferably arranged substantially perpendicular to the longitudinal direction of the concentrator pad, wherein the tension elements cause a tension of the support frame in the longitudinal direction of the concentrator pad.
    In order to uniformly clamp the anchoring device in the longitudinal direction of the concentrate pad, it is advantageous if the at least two support frames on both longitudinal sides of the concentrator pad each have at least one clamping element, preferably at least two cross-stretched chips elements are interconnected.
    In order to achieve a tensioning of the suspension device, it is advantageous if at least one support frame, in particular a bezo¬gen on the longitudinal direction of the concentrator pad front Trä¬gerrahmen and / or with respect to the longitudinal direction of Kon¬zentrator-pad rear support frame on another Span¬nelement is tensioned on a floor element. Preferably, tensioning elements on both longitudinal sides of the concentrator pad are guided by a bottom element on the front side of the concentrator via the individual support frames to a bottom element on the rear side of the concentrator.
    To the tracking of the concentrator pad to the sun, that is. the instantaneous position of the sun over the location, it is of advantage if the pivoting device comprises at least one pivoting element enclosing the concentrator cushion in its circumferential direction, in particular a pivoting ring, preferably several in the longitudinal direction of the concentrator Pads spaced pivoting elements, in particular pivot rings, each suspended from a support frame of Aufhängeeinrich¬. Such pivoting or rotating rings are known in the art, cf. e.g. WO 2012/145774, known per se. In the prior art, however, the swivel rings were supported on the underside on roller bearings. The disadvantages of this embodiment can now be overcome by suspending the pivoting rings on the suspension device.
    For tracking the concentrator pad to the sun gear it is advantageous if a pivot bearing device, in particular a roller bearing, is provided between the suspension device and the pivoting device. Such roller bearings are known in the art, cf. e.g. WO 2012/145774, known per se. The roller bearing has roller elements, which are particularly provided on a trolley. The roller elements are connected to a drive, wherein the roller elements generate a torque in the driven state by a frictional connection when rolling on the pivoting device, which causes a pivoting of the pivoting device with the concentrator pad about an axis, in particular about the longitudinal axis of the concentrator pad.
    In order to improve the force application to the pivoting device, the pivot bearing device preferably has a first roller bearing on the first frame element of the suspension device and a second roller bearing on the second frame element of the suspension device. Thus, the driving force is transmitted to at least two places on the pivoting device.
    According to a particularly preferred embodiment, the pivot device has a guide element for the roller bearing, wherein an outer roller element for rolling on the upper side of the guide element and an inner roller element for rolling on the inside of the guide element are provided. The inner roller element is in this case provided for normal operation, while the outer roller element is set up against lifting of the concentra¬ tion pad at higher wind loads. The expressions "inside" and "outside" refer to the radial extent of the concentrator pad.
    Preferably, the pivoting means comprises at least one pivoting member of I-shaped or T-shaped cross-section, with an upper flange of the I-shaped or T-shaped pivoting member being formed as a guide member for the roller bearing. Thereby, the pivoting member can be made of a standard part, whereby the pivoting member Manufacturing costs can be reduced, where at the same time the upper flange is designed as a guide element for Rol¬lenlagerung.
    In order to shield the concentrator pad, if necessary, especially when strong wind loads occur, it is favorable if a covering device is provided on the suspension device, which between a protective position at least partially covering the concentrator pad and the concentrator pad essentially completely exposed arranged stowage position can be transferred. Preferably, one cover device is attached to each adjacent support frame. The covering device may have lamellar elements which are arranged in the stowed position in a folded state and in the protection position in an unfolded state. The covering device is preferably arranged vertically in the protective position in the vertical position. In the protective position, preferably only the lower part of the concentrator pad is shielded, the upper part of the concentrator pad with the entry window being left open.
    According to a particularly preferred embodiment, the pivoting device is connected to a holding device for the concentrator cushion, which has at least one longitudinal carrier, in particular a truss carrier, extending in the longitudinal direction of the concentrator cushion. The side rail preferably extends substantially the entire length between opposite end portions of the concentrator pad. Thereby, the forces acting on the Kon¬zentrator cushion can be absorbed evenly and ab¬getragen on the pivoting device and the anchoring device. This embodiment has a considerably higher stability, in particular with respect to wind forces, than that in the prior art, cf. WO 2012/145774, provided local attachment points between the pivot rings and the Konzent¬rator cushion. It is particularly advantageous that influences on the curvature of the reflector film can be reduced by arranging the longitudinal members, as a result of which the energy yield can be substantially increased.
    In order to prevent undesired deformations of the concentrator cushion during operation, it is favorable if the holding device for the concentrator cushion has a first longitudinal beam, in particular a first truss beam, and a second longitudinal beam, in particular a second truss beam in which the first (upper) side member is connected to one of the solar radiation facing top of the concentrator pad and the second (lower) side member is connected to a side remote from the solar radiation underside of the concentrator pad. Accordingly, the first side member is connected to a cover film of the concentrator cushion having the entrance window by way of a fastening opening or passage opening sealed on all sides.
    On the first side member of the absorber is suspended. The second longitudinal member is connected via a further sealed on all sides Befes-tigungs- passage opening with a bottom foil of Konzentra¬tor pillow. As a result, the concentrator can be stabilized in the longitudinal direction. For sealing at the fastening openings, a welt system may be provided, an example of such a welt system being shown in WO 2012/145774. Both longitudinal beams are preferably arranged inside the concentrator pad.
    In operation, the concentrator pad is mounted on the anchoring device.
    The invention will be explained below with reference to a preferred Ausfüh¬ for example, to which, however, it should not be limited, even further. In the drawing show:

Concentrator pad 2 has a cover film element 3 "with a light-transmitting entrance window 3 for coupling in sun radiation and a reflector film which divides concentrator pad 2 into at least two cavities 4, 5 and curved during operation 6 for concentrating the solar radiation in an absorber 1 '. The reflector foil 6 has a mirror surface 6 ', which bundles the coupled-in solar radiation in the direction of the absorber 1'. The absorber 1 ', which is also to be understood as a solar panel, is located in the focus area of the mirror surface 6' within the upper cavity 4 of the concentrator pad 2 adjoining the inlet window 3. As absorber 1 ' In particular, a medium-flow pipe or a photovoltaic element may be provided. The concentrator can thus be used both for concentrated photovoltaics (CPV = Concentrated Photovoltaics) and for concentrated solar thermal energy (CSP = Thermal Concentrated Solar Power). During operation of the concentrator, a pressure difference is formed in the gas-filled cavities 4, 5, whereby the reflector film 6 is arched uniformly concave, so that the coupled-in solar radiation is focused by the mirror surface 6 'into the absorber 1'. The concentrator pad 2 is designed to be self-supporting in the state filled with compressed air in the cavities 4, 5, so that a considerably lower weight can be achieved compared to conventional solar concentrators. As known in the art, the concentrator pad 2 is made up of individual thin-walled (plastic) films; for the entrance window 3, a transparent film is provided.
    As further seen in Fig. 1, a pivoting device 7 is provided for pivoting the concentrator pad 2. The
    Pivoting device 7 has a plurality of pivoting elements in the form of swivel rings 8, which enclose the concentrator pad 2 in its circumferential direction. The swivel rings 8 of the swivel device 7 together form a tracking system in order to track the concentrator pad 2 during operation to the sun's path. For this purpose, the pivot rings of the pivoting device 7 are designed to pivot the concentrator pad 2 about at least one axis of the concentrator pad 2, in this case in particular the longitudinal axis of the concentrator pad 2.
    As is further apparent from FIGS. 1, 2, an anchoring device 9 is also provided for the pivoting device 7, wherein the anchoring device 9 in the embodiment shown has a suspension device 10 for suspending the pivoting rings 8 of the pivoting device 7. The suspension device 10 has a plurality of support frames 11 spaced apart in the longitudinal direction 2 '' 'of the concentrator pad 2 (cf., Fig. 1c), which have fastening points for the pivot rings 8 of the pivoting device 7.

In addition, the support frame 11 has a third frame member 14 above the pivot rings 8 with the concentrator pad 2. The first frame element 12 on one longitudinal side of the concentrator pad 2 is connected via the third frame element 14 to the second frame element 13 on the other longitudinal side of the concentrator pad 2. Accordingly, the support frame 11 extends arc-shaped from one longitudinal side of the concentrator pad 2 over the concentrator pad 2 on the other longitudinal side of the Kon¬zentrator-pad second

The second frame part 12b, 13b is angled inwardly from the upper end of the first frame part 12a, 13a towards the concentrator pad 2.
    As is further apparent from FIGS. 1, 2, the first frame element 12, the second frame element 13 and the third frame element 14 are designed as elongated profile elements which, in the embodiment shown, have an I-shaped cross section. The frame members 12, 13, 14 are arranged in a plane generally perpendicular to the longitudinal direction of the concentrator pad 2.
    As is further apparent from FIG. 1, the suspension device 10 has a plurality of carrier frames 11, which in the embodiment shown are three, which are connected to one another via a plurality of clamping elements 15 in the form of cable elements. The number of Trägerrah¬men 11 depends on the length of the concentrator pad 2. The support frames 11 each carry a pivot ring 8 which surrounds the concentrator pad 2. In the embodiment shown, on the one hand, the first frame elements 12 of the support frames 11 are braced on one longitudinal side of the concentrator pad 2 via tensioning elements 15, on the other hand clamping elements 15 are provided between the second frame elements 13 of the support frames 11 on the other longitudinal side of the concentrator pad 2 , On both longitudinal sides, two clamping elements 15 between the support frame 11 are cross tensioned in the embodiment shown. The front support frame 11 'and the rear support frame 11' ', each with respect to the longitudinal direction of the Konzent¬rator pad 2, are clamped on other clamping elements 16 on both longitudinal sides of the concentrator pad 2 on bottom elements 17. In the embodiment shown, the further clamping elements 16 are formed by end regions of clamping elements 15 between the carrier frame 11.

In the embodiment shown, a first roller bearing 19 is provided on the first frame element 12 of the suspension device 10 and a second roller bearing 20 is provided on the second frame element 13 of the suspension device 10.
    As can be seen from FIG. 3, the swivel rings 8 each have a guide element 21 for the roller bearings 19, 20, wherein outer roller elements 22 on the upper side of the guide element 21 and inner roller elements 23 roll on the inside of the guide element 21. The roller elements 22, 23 of the Rol¬lenlagerungen 19, 20 are mounted on trolleys 24 which are secured to the underside of the pivot ring 8.
