DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will describe in detail the specific implementation of the present disclosure with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure and is not used to limit the present disclosure.

[0024] In this disclosure, unless otherwise specified, the orientation terms such as "upper, lower, top, bottom" generally refer to the upper, lower, top, and bottom of the corresponding components in the gravity direction under the use state, and "inner, outer" refer to the inner and outer relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0025] The present disclosure provides a photovoltaic panel fixing device, including: a fixing plate 1 for installing a photovoltaic panel, and the fixing plate 1 is inclined; a first water tank 2 disposed on the lower side of the fixing plate 1, the first water tank 2 having a water inlet 21, and the upper surface of the photovoltaic panel is within the opening range of the water inlet 21; and a spraying device 3 disposed on the higher side of the fixing plate 1 and above the photovoltaic panel to spray the photovoltaic panel and make the sprayed water flow into the first water tank 2, and the spraying device 3 is connected to the first water tank 2.

[0026] Through the above technical solution, in the photovoltaic panel fixing device provided by the present disclosure, the photovoltaic panel is installed on the inclined fixing plate 1 to face the sun. The spraying device 3 is connected to the first water tank 2 and is used to spray the photovoltaic panel for cleaning. The spraying device 3 is disposed on the higher side of the fixing plate 1 so that the water flows from top to bottom to clean the photovoltaic panel. The first water tank 2 is disposed on the lower side of the fixing plate 1 and the upper surface of the photovoltaic panel is within the opening range of the water inlet 21. In this way, after the sprayed water cleans the photovoltaic panel, it flows back into the first water tank 2 along the inclined photovoltaic panel for recycling, so that the sprayed water can be recycled. The water in the first water tank 2 comes from the collected rainwater. When it rains, the rainwater falls on the surface of the photovoltaic panel and then flows into the first water tank 2. Of course, the first water tank 2 can also be manually replenished with water. A filter screen is provided at the water inlet 21 of the first water tank 2 to filter the rainwater and the sprayed water.

[0027] As an alternative embodiment, as Figure 4 shown, the first water tank 2 extends in the same direction as the lower side edge of the fixing plate 1 and the length of the water inlet 21 is greater than or equal to the length of this side edge. The spraying device 3 is configured as a spray pipe, and a plurality of nozzles are provided on the spray pipe. The spray pipe extends in the same direction as the higher side edge of the fixing plate 1. The length of the water inlet 21 is greater than or equal to the length of the side edge of the fixing plate 1, so that the sprayed water can all enter the water inlet 21. The spraying device 3 is a spray pipe, which increases the spraying area to clean the photovoltaic panel comprehensively. For example, a baffle can be provided on the side of the fixing plate 1 to block the sprayed water and prevent the sprayed water from flowing away from the side of the fixing plate 1.

[0028] As an alternative embodiment, as Figures 3-4As shown in the figure, the photovoltaic panel fixing device further includes a water pump group 9 and a pipeline 10. The water inlet end of the pipeline 10 is connected to the first water tank 2, and the water outlet end is connected to the spraying device 3. The water pump group 9 is arranged on the pipeline 10. The water pump group 9 pumps the water in the first water tank 2 into the spraying device 3 through the pipeline 10 to spray the photovoltaic panel.

[0029] Optionally, the photovoltaic panel fixing device further includes a second water tank 8. The water pump group 9 includes a first water pump 91 and a second water pump 92. The pipeline 10 includes a water suction pipe 101 and a water delivery pipe 102. The water inlet end of the water suction pipe 101 is connected to the first water tank 2, and the water outlet end is connected to the second water tank 8. The first water pump 91 is arranged on the water suction pipe 101. The water inlet end of the water delivery pipe 102 is connected to the second water tank 8, and the water outlet end is connected to the spraying device 3. The second water pump 92 is arranged on the water delivery pipe 102. First, the first water pump 91 and the water suction pipe 101 pump the water in the first water tank 2 into the second water tank 8, and then the second water pump 92 and the water delivery pipe 102 pump the water in the second water tank 8 into the spraying device 3. The second water tank 8 is arranged below the higher side of the fixing plate 1. Adding the second water tank 8, on the one hand, the second water tank 8 is closer to the spraying device 3, ensuring the spraying pressure of the spraying device 3. On the other hand, it can increase the water storage capacity to ensure more sufficient spraying water in the wild.

[0030] As an alternative implementation, as Figures 1-2 shown, the photovoltaic panel fixing device further includes a cleaning device 4. The cleaning device 4 is movably arranged above the fixing plate 1 along the inclined direction of the fixing plate 1. If the dust on the photovoltaic panel is thick, spraying water alone cannot completely clean the photovoltaic panel. Therefore, the cleaning device 4 is provided. The cleaning device 4 is movably arranged to cooperate with the spraying device 3 to clean the photovoltaic panel, making the photovoltaic panel cleaner.

[0031] Optionally, the cleaning device 4 includes a driving device 41, a first screw 44, a cleaning slider 42, a cleaning brush, and a mounting bracket 43. The mounting bracket 43 is arranged on one side of the fixing plate 1 and extends along the inclined direction of the fixing plate 1. The first screw 44 is arranged in the mounting bracket 43. One end of the first screw 44 is rotatably connected to the mounting bracket 43, and the other end extends outside the mounting bracket 43 and is connected to the driving device 41. For example, the driving device 41 is a driving motor. On the side of the mounting bracket 43 facing the inside of the fixing plate 1, there is a first opening 431 extending in the same direction as the mounting bracket 43. One end of the cleaning slider 42 extends into the first opening 431 and is threadedly connected to the first screw 44. The other end of the cleaning slider 42 extends to the inner side of the fixing plate 1 in a direction perpendicular to the first screw 44. The cleaning brush is arranged on the side of the cleaning slider 42 close to the fixing plate 1 to clean the photovoltaic panel. The first opening 431 serves as a slideway for the cleaning slider 42 to move along the slideway. The driving device 41 drives the first screw 44 to rotate, the first screw 44 drives the cleaning slider 42 to move linearly, and the cleaning brush arranged at the bottom of the cleaning slider 42 is used to clean the photovoltaic panel.

[0032] As an alternative embodiment, as Figures 1-4 shown, the photovoltaic panel fixing device further includes an irrigation device 7 arranged below the fixing plate 1. The irrigation device 7 is arranged on at least one of the first water tank 2 or the second water tank 8. It can be arranged at the bottom of the first water tank 2, or at the bottom of the second water tank 8, or irrigation devices 7 can be arranged at the bottoms of both the first water tank 2 and the second water tank 8. For example, the irrigation device 7 includes an irrigation pipe and a control valve. The irrigation pipe is connected to at least one of the first water tank 2 and the second water tank 8. The control valve controls the opening and closing of the irrigation pipe to irrigate the vegetation below the photovoltaic panel fixing device, collect rainwater when it rains, and irrigate the vegetation when it does not rain. Especially in desert areas, the desert has little precipitation and a large potential evaporation, resulting in extremely low soil moisture content and making it difficult to maintain the growth of sand-fixing plants. At this time, the irrigation device 7 is required to irrigate the vegetation.

[0033] As an alternative embodiment, as Figures 1-3 shown, the photovoltaic panel fixing device further includes a first support device 5 and a second support device 6 for supporting the fixing plate 1. The second support device 6 is arranged at the bottom of the lower side of the fixing plate 1 and is hinged to the fixing plate 1. The height of the first support device 5 is adjustably hinged to the higher side of the fixing plate 1 to adjust the inclination angle of the fixing plate 1, so as to control the angle between the photovoltaic panel and the sunlight, so that the light and the photovoltaic panel maintain the best angle. For example, the photovoltaic panel is inclined at different angles in different seasons. The first support device 5 and the second support device 6 are both hinged to the fixing plate 1. In this way, no matter how the angle of the fixing plate 1 is adjusted, the first support device 5 and the second support device 6 can ensure being vertically arranged.

[0034] Optionally, the first support device 5 includes a support frame 51, a second screw 54, a moving block 53, and a rotating member 52. The support frame 51 is vertically arranged. The second screw 54 is arranged inside the support frame 51, and the bottom end of the second screw 54 is rotatably connected to the support frame 51, and the top end extends outside the support frame 51 and is connected to the rotating member 52. For example, the rotating member 52 is a rotating knob. On one side of the support frame 51 facing the fixing plate 1, there is a second opening 511 extending in the same direction as the support frame 51. One end of the moving block 53 extends into the second opening 511 and is threadedly connected to the second screw 54. The other end of the moving block 53 is hinged to the fixing plate 1. By rotating the rotating member 52, the second screw 54 rotates, so that the moving block 53 moves up and down along the direction of the support frame 51 to adjust the height of the higher side of the fixing plate 1.

[0035] The photovoltaic panel fixing device in the present disclosure can be used in desert areas. Because the wind and sand are relatively large in desert areas and the photovoltaic panels are easily covered with dust, the spraying device 3 and the cleaning device 4 need to be provided to clean the photovoltaic panels. Also, because the climate in desert areas is dry, the solar radiation is strong, and the evaporation is large, it is very easy to lack water. Therefore, it is necessary to recycle the sprayed water to avoid wasting water resources as much as possible. The soil water content in desert areas is extremely low, making it difficult to maintain the growth of sand-fixing plants. At the same time, due to the shading of the photovoltaic panels, the precipitation obtained under the photovoltaic panels is even less, and the sand-fixing shrubs under the photovoltaic panels are more difficult to survive due to lack of water. Therefore, the irrigation device 7 is provided to collect water when it rains and irrigate when it does not rain.

[0036] The present disclosure also provides a photovoltaic panel assembly, including: the above-mentioned photovoltaic panel fixing device; and a photovoltaic panel. The photovoltaic panel is arranged on the photovoltaic panel fixing device. The photovoltaic panel can be cleaned by the spraying device 3. After the sprayed water cleans the photovoltaic panel, it flows back into the first water tank 2 along the inclined photovoltaic panel for recycling, so that the sprayed water can be recycled.

[0037] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0038] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0039] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
