    专利说明:

    The present invention relates to a tracking device with the features of the preamble of claim 1 and an arrangement with two tracking devices for photovoltaic systems.
    In the prior art, there is a desire to move through the tracking device as large as possible surfaces of the photovoltaic system (hereinafter "PV system") with as few motors as possible.
    As actuators z. Linear actuators are known, however, which have the disadvantage of being extremely unfavorable to the action of external forces (eg in the form of wind), especially at the maximum extension position, since it is easy for the linear actuator to buckle or to overload the linear actuator Connection points can come. Due to the mounting size, you usually have to be satisfied with a very poor lever for the introduction of force.
    It is also known (eg WO 2013/190196 A2) to mechanically couple a plurality of separate tracking devices in such a way that they can be driven by a single motor. The fewer drives required, the lower the overall costs for motors, for the control and service costs and the cabling. If the mechanical coupling z. B. via a shaft transverse to the rows of photovoltaic modules, it may be due to the wind loads occurring excessive Torsionsschwingungen in the axis of rotation of the PV system, which must be controlled.
    The object of the invention is to provide a generic tracking device in which the problems described with regard to the linear actuator are reduced or eliminated or the provision of an arrangement with at least two adjustment devices in which torsional vibrations are reduced or prevented.
    This object is achieved by a tracking device having the features of claim 1 and an arrangement having the features of claim 7. Advantageous embodiments of the invention are defined in the dependent claims.
    The design of the adjusting device in the form of a double toggle lever has a number of advantages. A particular advantage is that especially with the maximum adjustment of the tracking device in one direction (usually about 45 °, 0 ° corresponds to a horizontally oriented tracking device) is given a particularly good stability against the influence of external forces (v. In this case, namely, the two knees of the adjusting device are very close to each other and the risk of buckling is minimal. Suction forces are transmitted in this position in the form of tensile forces on the actuator. With regard to the maximum adjustment of the tracking device in the other direction (usually about minus 45 °), the two knees are far away from each other. Here suction forces are transmitted in the form of compressive forces on the adjustment, which is also easy to control.
    The double toggle lever gives a much better leverage compared to a linear actuator, since a much better stroke ratio of the minimum to maximum stroke length can be achieved.
    In the arrangement according to the invention, only one motor is required per row of tracking devices. Several rows can be arranged one behind the other. For a plurality of rows, much less control cabinets are required due to the saving of motors than in the prior art (eg, one megawatt equivalent, only one control cabinet in the invention compared to ten control cabinets by the use of multiple linear actuators).
    Through the use of several adjusting devices (double toggle lever), higher wind glare can be removed while preventing torsional vibrations at the same time as with a selective connection of a linear actuator.
    Embodiments of the invention will be discussed with reference to the figures. Show it:
    1 is a view of FIG. 1 in the direction of the shaft FIG. 3 is a view of FIG. 2 in a direction transverse to the shaft Fig. 4 a detailed view of the shaft
    6 shows a perspective view of an arrangement of two tracking devices according to the invention according to a variant of FIG. 1 with a different arrangement of the motor. FIG
    7 shows a perspective view of a further arrangement of two tracking devices according to the invention according to FIG. 1
    Fig. 1 shows a single anchored in a substrate 15 tracking device 1 with four adjusting devices 5 in this embodiment (the number of which can be varied as desired). Visible is a single motor 3, which drives all four adjusting devices 5 via a single shaft 4 and thus allows a uniform, torsion-free adjustment of the PV system 2 connected to the tracking device 1 over the entire length of the tracking device 1. The tracking device 1, starting from a horizontal position (0 °) in both directions of rotation by an amount (usually about 45 °) can be adjusted.
    It can also be seen in FIG. 1 (see also FIG. 5) that the stationary parts 6 of the tracking device 1, on which the pivoting parts 7 are pivotably mounted, can be designed to be height-adjustable. For this purpose, they are arranged displaceably fixable in serving as uprights 16 profiles.
    Fig. 2 reveals the motor 3, which may be formed for example as a geared motor.
    Fig. 2 and Fig. 3 show an adjustment of the tracking device 1 of about 30 °.
    Fig. 4 shows a detail view of the shaft 4, wherein a single portion of the plurality of sections having shaft 4 is shown. The section shown has two oppositely formed threaded portions 11, a arranged between these threaded portions section 13 and end attachment portions 14. About the connection sections 14, the z. For example, other than shown may have polygonal cross-section, the portion shown (eg., Via an adapter plug, which serves the power transmission and can compensate for length tolerances in the assembly of the shaft 4) can be connected to other sections to the shaft 4. On the shaft 4 are detached from the associated knees 8 of the toggle nuts 12 are shown, wherein the one nut 12, the thread 9 and the other nut 12 has the oppositely formed thread 10. About the pins 12b, not shown legs of the toggle lever with the nuts 12 are connected. It can be provided that the sliding nuts 12 are formed as a metal casting (eg bronze casting) or as a plastic part. The running nuts 12 may be formed in several parts. The sliding nuts 12 may have dirt scrapers (not shown).
    It is preferably provided that the threads 9, 10 of the toggle lever and the threaded portions 11 of the shaft 4 are self-locking.
    6 and 7 each show a perspective view of an arrangement of two tracking devices 1 according to the invention for PV systems 2. These have a common shaft 4 and a single motor 3. FIGS. 6 and 7 differ in the choice of the arrangement of the motor 3.
    There are also other possible arrangements of the individual modules of the PV systems 2 as shown in FIGS. Possible. The sizes of the adjusting devices 5 can be scaled accordingly in order to operate larger areas of the PV systems 2 can.
