    专利说明:

    [0001] The present invention relates to a device for the sequential collection of rainwater, in particular for the purpose of studying the evolution of the radioactivity of rainwater. study of the evolution of radioactivity of rainwater. We already know, in the state of the art, a collection device with a large receptacle, which fills gradually with the rain. Since all the rains are collected in the same receptacle, such a collection device does not allow to study an evolution of the activity of rainwater over time. In order to study this evolution, there is also known, in the state of the art, a so-called sequential collection device comprising a plurality of collection receptacles intended to receive rainwater, these receptacles being able to be opened or closed independently. However, such a collection device is particularly expensive, and it requires a power source to supply means for opening and closing the receptacles. This energy is generally electricity delivered over an electrical network, so that such a collection device has constraints related to its connection with the power network, which limit its installation possibilities in the environment.
    [0002] The object of the invention is in particular to remedy these drawbacks, by providing a sequential type rainwater collecting device that does not require a source of energy, while remaining economical. To this end, the invention particularly relates to a rainwater collecting device, comprising a plurality of collection receptacles for receiving rainwater, each collection receptacle having a circumferential wall and a bottom wall. characterized in that: - the collection receptacles are stacked, forming a stack along a vertical axis, - each receptacle arranged above another adjacent receptacle has a water flow opening in its lower wall, this flow opening opening into this other adjacent receptacle, - each receptacle arranged below another adjacent receptacle houses a floating shutter element movable along the vertical axis between a low position and a high position according to the amount of water in this receptacle, the closure member having a shape complementary to that of the water flow opening of the adjacent receptacle arranged above, closing this flow opening in the high position. The collection containers being stacked, the rainwater flows through these receptacles, in particular through the flow openings, to a lower receptacle arranged lower. As this lower receptacle fills, the floating shutter member accommodated in this receptacle moves from its down position to its up position. In the up position, the flow opening opening in this lower receptacle is closed, and the rainwater now fills a new receptacle. Thus, in the long term, the receptacles comprise rainwater corresponding to different precipitations, which do not mix. It therefore clearly appears that the collection device according to the invention makes it possible to study the evolution of the state of the rainwater. Since the closing of the receptacles is carried out mechanically by the floating sealing elements, the collecting device according to the invention does not require any supply source. Finally, the collection device according to the invention has a simple structure, and therefore particularly economical. A collection device according to the invention may further comprise one or more of the following features, taken alone or in any technically feasible combination. The plurality of receptacles comprises: an upper receptacle, arranged at the top of the stack, whose bottom wall comprises a flow opening, a lower receptacle, arranged at the bottom of the stack, housing a closure element, and at least one intermediate receptacle, arranged between the upper receptacle and the lower receptacle in the direction of the vertical axis, having on the one hand a bottom wall having a flow opening and housing on the other hand a closure element floating. - The receptacles are assembled detachably to each other, for example by screwing or latching. Each receptacle comprises a dump channel passing through its circumferential wall close to its bottom wall, each dump channel being provided with a valve. - The lower wall of each receptacle has a concavity, in which opens the emptying channel of the receptacle. - A seal is arranged between each closure member and each complementary flow opening, the seal being carried by the closure member or by a periphery of the flow opening. - Each receptacle housing a closure member comprises magnetic means 5 for holding the shutter element in the high position. - The magnetic means comprise an annular element, housed in the receptacle near the bottom wall of the adjacent receptacle located immediately above, one of the annular element and the closure element being made of magnetic material and the other of ferromagnetic material. Each closure member has a cone shape, and each receptacle housing a closure member has an element having a frustoconical opening for receiving the shutter element in the up position. The plurality of receptacles includes an upper receptacle, arranged at the top of the stack, comprising an overflow channel passing through its circumferential wall at an upper end of this upper receptacle. The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures in which: FIG. 1 is a diagrammatic sectional view of a collection device rainwater according to an exemplary embodiment of the invention, wherein the collection containers are open; - Figure 2 is a schematic sectional view of a detail of the collection device of Figure 1, showing a closed collection receptacle. There is shown in FIG. 1 a device 10 for collecting rainwater according to an exemplary embodiment of the invention. The collection device 10 has a plurality of receptacles 12A, 12B, 12C for receiving rainwater. Each collection receptacle 12A, 12B, 12C has a circumferential wall 14, and a bottom wall 16. Each collection receptacle 12A, 12B, 12C, for example, has a generally cylindrical shape with a circular section, extending along a Z-axis. The collection receptacles 12A, 12B, 12C are stacked so as to form a stack along the Z axis. The Z-axis will in this description be called the "vertical axis" because, for normal use of the collection device 10, the collection receptacles 12A, 12B, 12C must be stacked vertically.
    [0003] In the present description, the terms "upper", "lower", "above", "below", "up" and "down" are defined along this vertical axis Z, with their conventional meaning. In the example shown, the plurality of receptacles 12A, 12B, 12C includes an upper receptacle 12A, arranged at the top of the stack, an intermediate receptacle 12B, and a lower receptacle 12C, arranged at the bottom of the stack. The intermediate receptacle 12B is thus arranged between the upper receptacle 12A and the lower receptacle 12C in the direction of the vertical axis Z. According to a variant not shown, the stack could comprise at least two identical stacked intermediate receptacles 12B. between the upper receptacle 12A and the lower receptacle 12C. According to another variant not shown, the stack may not comprise an intermediate receptacle 12B, but only an upper receptacle 12A and a lower receptacle 12C.
    [0004] More particularly, the number of receptacles is chosen according to the number of rainwater withdrawals that it is desired to carry out. Advantageously, the receptacles 12A, 12B, 12C are assembled detachably to each other, for example by screwing or snapping. Each receptacle 12A, 12B, 12C thus forms a module, so that the collection device 20 is modular and can simply present a desired number of receptacles. In order to allow a flow of rainwater to the lower receptacle 12C, each receptacle 12A, 12B arranged above another adjacent receptacle 12B, 12C has a water outlet opening 18 formed in its lower wall 16 this flow opening 18 opening into said other adjacent receptacle 12B, 12C. More particularly, the upper receptacle 12A, as well as each intermediate receptacle 12B, has such a flow opening 18 in its bottom wall 16. In contrast, the lower receptacle 12C does not have a flow opening in its lower wall 16 Alternatively, the lower receptacle 12C 30 has a structure identical to that of the intermediate receptacle 12B, in which case its flow opening 18 is closed, for example by a base on which is disposed this lower receptacle 12C. Furthermore, each receptacle 12B, 12C arranged below another adjacent receptacle 12A, 12B houses a floating shutter member. This floating sealing member 20 is movable along the vertical axis Z between a low position and a high position, depending on the amount of water in this receptacle 12B, 12C.
    [0005] The closure member 20 has a shape complementary to that of the water flow opening 18 of the adjacent receptacle 12A, 12B arranged directly above, so that it is likely to seal this opening 18 when in the up position, as shown in Figure 2.
    [0006] In contrast, the closure member 20 has a shape allowing the flow of water to the adjacent receptacle 12B, 12C arranged below when in its down position. For this purpose, the closure member 20 may have water passage grooves in its lower part, have feet raising the shutter element 20 in the low position, or have any other means that can be used to authorize the closure. flow of water. Advantageously, the collection device 10 comprises means for translational guidance of each closure member 20 along the vertical axis Z. These guide means can take any conceivable shape. For example, in the example shown, each closure member 20 has a cone-shaped shape, and each receptacle 12B, 12C housing such a closure member 20 has an annular element 22 having a frustoconical opening for guiding the shutter member 20 and receiving this shutter member 20 in the up position. This annular element 22 allows both to guide the shutter member 20 as it moves to its up position and to optimize the seal between the two adjacent receptacles 20, by increasing the contact area between the element 20 and the annular element 22. Advantageously, a seal (not shown) is arranged between each closure element 20 and each complementary flow opening 18. The seal is for example carried by the closure element 20, or alternatively by a periphery of the flow opening 18, for example by the annular element 22. According to an advantageous variant, each receptacle 12B, 12C accommodating an element shutter 20 comprises magnetic means for holding the closure member 20 in the upper position, ensuring the maintenance of the closure of this receptacle 12B, 12C.
    [0007] The magnetic means 24 comprise for example a holding element, housed in the receptacle 12B, 12C near the bottom wall of the adjacent receptacle situated immediately above, one of the holding element and the element of shutter 20 being magnetic material, and the other ferromagnetic material. In the example shown, the holding element is formed by the annular element 22.
    [0008] For example, the closure member 20 is made of non-stainless steel, coated with a polymer protecting the steel from rusting. It is clear that the lowest receptacle that is not yet filled fills with the rains flowing into the receptacles, causing its shutter member 20 to rise to its up position. Once this high position is reached, this closure member 20 closes the opening flow opening in this receptacle, so that this receptacle is thus closed and isolated from other receptacles. It is then the next higher receptacle that will be filled in the same way.
    [0009] The receptacles are thus filled one by one, one after the other, until the upper receptacle 12A is also filled. Since the receptacles are filled one after the other, they contain rainwater corresponding to different precipitations, which makes it possible to observe a change in the state of the rainwater.
    [0010] Optionally, the water collecting device 10 is associated with a meteorological station (not shown), which records the precipitation and thus allows to deduce the dates of the precipitation corresponding to the different samples. In order to take water from each receptacle 12A, 12B, 12C, each receptacle comprises a dump channel 26 passing through its circumferential wall 4 near its lower wall 16. Each dump channel 26 is provided with a valve 28, which is closed during the collection of rainwater, and opened during a sampling of water from the corresponding receptacle. Advantageously, each bottom wall 16 has a concavity 30 into which the emptying channel 26 opens. This concavity 30 makes it possible to draw the water towards the emptying channel 26, in order to ensure that all the water in the receptacle is well evacuated by the emptying channel 26. Once the rainwater collected, it is analyzed in a manner known per se. Optionally, the upper receptacle 12A includes an overflow discharge channel 32, passing through its circumferential wall 14 at an upper end of this upper receptacle 12A. Thus, the upper receptacle 12A can not be filled beyond this discharge channel 32 Finally, the collection device 10 advantageously comprises an inlet cone 34, arranged above the upper receptacle 12A, facilitating entry rainwater in the collection device 10.
    [0011] It will be appreciated that the invention is not limited to the embodiment previously described, but could have various variants.
    [0012] In particular, each shutter element could have a shape different from that described above. 5
