[0061] 4. The utility model can work stably under different water amount environments by the close cooperation of the control device and the gravity sensor, the spraying system can work efficiently under various environmental conditions, and the adaptability and reliability of the system are improved.

[0062] Generally, the photovoltaic assembly 1 is spliced by a plurality of photovoltaic panels, and the photovoltaic assembly 1 is arranged obliquely to maximize the reception of sunlight and improve the photovoltaic power generation efficiency. Figure 1 It can be arranged below the row of photovoltaic panels closest to the ground of the photovoltaic assembly 1, so that the water flow converges to the water collecting plate from top to bottom, and then the rainwater or other water sources are effectively collected, the accumulation or influence of the water flow on the surface of the photovoltaic panel is avoided, and convenience is provided for subsequent water resource utilization.

[0063] The utility model does not limit the specific structure of the photovoltaic water collecting plate 2. In some embodiments, the photovoltaic technology plate can be arranged to include a water collecting groove or a water collecting cavity.

[0064] In the embodiment of the utility model, reference Figure 2 As shown in the figure, the photovoltaic water collecting plate 2 comprises:

[0065] The first channel 25 is connected with the photovoltaic component 1 and has a first opening 21.

[0066] The second channel 26 is in a free state and has a second opening 22.

[0067] The water storage part 23 is located between the first channel 25 and the second channel 26 and has a groove.

[0068] The first opening 21 and the second opening 22 are in the same opening direction and are opposite to the opening of the groove, and the opening of the groove faces the photovoltaic component 1, so as to collect the water flowing out of the photovoltaic plate.

[0069] The first channel 25 is connected with the photovoltaic component 1 and has a first opening 21. The first channel 25 is connected with the photovoltaic component 1 and the photovoltaic water collecting plate 2, so as to ensure that the photovoltaic water collecting plate 2 can be connected with the photovoltaic component 1. The second channel 26 is independent of the first channel 25 and can play a role of water guide in some cases. Since the first opening 21 and the second opening 22 are opposite to the opening of the groove of the water storage part 23 and the opening of the groove faces the photovoltaic component 1, the first opening 21 and the second opening 22 are arranged towards the ground. In this way, when the amount of water flowing out of the photovoltaic component 1 is large, the first channel 25 and the second channel 26 can play a role of water guide to some extent, effectively guide the water overflowing from the water storage part 23 to the ground, so as to avoid that too much water accumulates on the surface of the photovoltaic component 1, reduce the potential influence of water accumulation on the component, and improve the drainage efficiency and water resource utilization rate of the whole system.

[0070] In some embodiments, the second channel 26 can be designed to be connected with the adjacent photovoltaic component 1 or can be designed not to be connected, and the utility model does not make specific limitation.

[0071] The design of the groove allows water to be gathered and stored inside the water collecting plate, so as to ensure that the water flow is effectively guided to the water storage part 23. Through the shape of the groove, the water flow is more efficiently guided and stored, and water waste is avoided.

[0072] In order to ensure that the water can be smoothly transmitted from the water storage part 23 to the automatic spraying device 3, in some embodiments, the water outlet hole 24 can be arranged on the water storage part 23, and the water outlet hole 24 is used for guiding the water in the water storage part 23 to the automatic spraying device 3.

[0073] The automatic spraying device 3 comprises a connecting part 31 and a spraying part.

[0074] The connecting part 31 is hollow inside and one end is connected to the spraying part, and the other end penetrates the water outlet hole 24, so as to connect the photovoltaic water collecting plate 2 and the automatic spraying device 3 and simultaneously connect the photovoltaic water collecting plate 2 and the spraying part.

[0075] In this way, by the existence of the water outlet hole 24, the connecting part 31 of the automatic spraying device 3 can be connected, not only the automatic spraying device 3 can be fixed, but also the water in the water storage part 23 can smoothly enter the spraying part along the connecting part 31, and the water transmission process is not hindered, so that efficient water flow management and spraying effect are realized.

[0076] In order to make the spraying effect more uniform and efficient, in some embodiments, the water outlet hole 24 can also be provided as a plurality of water outlet holes 24, and the existence of the plurality of water outlet holes 24 can effectively avoid that the water flow is concentrated in a certain point, causes pressure to the photovoltaic water collecting plate 2, and affects the service life of the photovoltaic water collecting plate 2. The plurality of water outlet holes 24 are uniformly arranged, which can ensure that the water flows into the spraying device from different positions of the photovoltaic water collecting plate 2 at the same time, thereby improving the spraying coverage area and avoiding the problems of too much or too little water flow in a local area.

[0077] Correspondingly, the automatic spraying device 3 corresponding to the water outlet hole 24 is also a plurality of automatic spraying devices 3, and the plurality of automatic spraying devices 3 correspond to the plurality of water outlet holes 24 one by one, so that each water outlet hole 24 can correspond to a spraying device, which not only can make the stress of the photovoltaic water collecting plate 2 uniform, but also can improve the water flow utilization efficiency, enhance the stability of the system and the spraying effect.

[0078] In some embodiments, the spraying part can include a nozzle, and the water in the spraying part is sprayed through the nozzle. In the utility model, the spraying part includes:

[0079] A water bucket is in communication with the connecting part 31 and includes a water collecting part 32 and a spraying part 33. The water collecting part 32 and the spraying part 33 are connected, and a plurality of spraying holes 331 are uniformly arranged around the spraying part 33. The water enters the water collecting part 32 through the connecting part 31 and is sprayed through the spraying holes 331.

[0080] Obviously, the water bucket is the core of the water collecting and spraying part, so in the utility model, the water bucket is designed to include the water collecting part 32 and the spraying part 33. The water collecting part 32 receives and stores water. When the water flow enters the spraying part from the connecting part 31, it first enters the water collecting part 32 and then enters the spraying part 33 through the water collecting part 32.

[0081] In the embodiment of the utility model, reference is made to Figure 3As shown, in order to further prevent the water from flowing too fast or too slow from affecting the spraying effect, the utility model provides a plurality of evenly spaced spray holes 331 around the spraying part 33, the uniform arrangement of the spray holes 331 ensures the uniform distribution of water, avoids the water flow concentrating in a certain area, and causes uneven spraying due to the water flow being too fast in one direction and too slow in another direction, thereby improving the uniformity and stability of the spraying effect.

[0082] Further enhance the stability and reliability of photovoltaic water collection automatic spraying system, in the utility model embodiment, still can set up pressure relief assembly 4 in the spraying part, for pressure regulation to the inside of the water bucket, when the pressure inside the water bucket is too high, pressure relief assembly 4 can automatically release part water amount or pressure, to ensure the normal operation of system, avoid the damage or influence of spraying effect caused by too high pressure to spraying device, by the regulation of the pressure inside the water bucket, can ensure that the system is stable when water flow changes, avoid the damage or uneven spraying caused by too high or too low water pressure, thereby improve the service life and efficiency of system.

[0083] In some embodiments, reference is made to Figure 3 As shown, the pressure relief assembly 4 can be further provided to include: a limiting block 41, arranged on the inner wall of the water bucket, located between the water collecting part 32 and the spraying part 33;

[0084] A water baffle 42 is located in the spraying part 33, having a pressure relief position and a water collecting position,

[0085] Wherein, in the pressure relief position, there is a gap between the water baffle 42 and the limiting block 41, the water in the water collecting part 32 enters the spraying part 33 through the gap, and is sprayed through the spray holes 331; in the water collecting position, the water baffle 42 abuts against the limiting block 41 to cooperatively block the water in the water collecting part 32 from entering the spraying part 33.

[0086] The limiting block 41 is arranged on the inner wall of the water bucket, located between the water collecting part 32 and the spraying part, providing a physical limit that can control the position of the water baffle 42 in different working states, thereby limiting and guiding the water flow. When the water amount in the water bucket increases and the pressure rises, the water baffle 42 will be adjusted to the pressure relief position, at this time there is a gap between the water baffle 42 and the limiting block 41, allowing the water in the water collecting part 32 to enter the spraying part through the gap and be sprayed through the spray holes, the water in the water bucket is released in time to prevent pressure accumulation. When the water amount in the water bucket is within a normal range, the water baffle 42 is in contact with the limiting block 41 to prevent the water flow from entering the spraying part, so as to maintain the accumulation of water amount in the water bucket and avoid unnecessary waste caused by excessive water flow entering the spraying device.

[0087] In the utility model embodiment, the water bucket bottom is also provided with a drain 34;

[0088] The pressure relief assembly 4 further comprises a pressure relief bucket 43 and an elastic member 44. The pressure relief bucket 43 is located below the water bucket and is used to receive the water flowing out of the water outlet 34. One end of the elastic member 44 is connected to the pressure relief bucket 43, and the other end penetrates through the bottom of the water bucket and extends into the water bucket to be connected to the water baffle 42.

[0089] The pressure relief bucket 43 is provided with a pressure relief opening for releasing the water in the pressure relief bucket 43.

[0090] In this way, the water outlet 34 at the bottom of the water bucket can share part of the water pressure, and the water flows into the pressure relief bucket 43. The sum of the gravity of the pressure relief bucket 43 and the pressure provided by the water in the water collecting portion 32 is greater than the tension of the spring, and the water baffle 42 moves to the pressure relief position. The water flows into the spraying portion 33 through the gap between the water baffle 42 and the limiting block 41. Part of the water is sprayed through the spraying hole 331, and the other part of the water enters the pressure relief bucket 43 through the water outlet 34. Since the pressure relief bucket 43 is provided with a pressure relief opening, the water in the pressure relief bucket 43 is slowly discharged, so that the tension of the spring gradually develops in the direction greater than the gravity. At this time, the water baffle 42 slowly rises to abut against the limiting block 41, and reaches the water collecting position.

[0091] The elastic member 44 can be a spring, a silica gel member or other specific elastic material.

[0092] In order to ensure that the water baffle 42 can exactly reach the pressure relief position during this process, a counterweight can be further arranged in the pressure relief bucket 43 in some embodiments.

[0093] In addition, in order to enable the spraying portion 33 to timely relieve pressure and enable the water discharged through the water outlet 34 to accurately enter the pressure relief bucket 43, the diameter of the water outlet 34 can be designed to be greater than the diameter of the pressure relief opening. In this way, when the water amount and water pressure in the water bucket are too high, the water outlet 34 releases most of the water flow through the larger diameter, preventing too much water from accumulating in the water bucket. The pressure relief opening is used to adjust the pressure in the pressure relief bucket 43, and the diameter thereof is designed to be smaller than that of the water outlet 34, which can prevent the water flow from being too fast or the water pressure from being too large to affect the stability of the movement of the water baffle 42.

[0094] In addition, the valve body can be arranged on the automatic spraying device 3, and a gravity sensor (which can be arranged on the side of the bottom of the photovoltaic water collecting plate 2 facing the ground, not shown in the figure) is arranged below the bottom of the photovoltaic water collecting plate 2. The valve body can be opened when the water amount is large, allowing the water flow to enter the automatic spraying device 3; and the valve body can be closed when the water amount is small, avoiding unnecessary spraying. The opening and closing of the valve body are controlled by the control device, and the signal processing of the control device is related to the sensed gravity of the gravity sensor (the valve body can be arranged on the connecting portion 31, at a position between the photovoltaic water collecting plate 2 and the spraying portion, not shown in the figure). The gravity sensor can be a sensor based on a capacitive type, a piezoelectric type or a micro-electromechanical system technology, and the utility model does not make specific limitations. The control device can be a microprocessor or a control unit with an intelligent sensing function, which automatically adjusts the opening and closing state of the valve body according to the gravity change of the water flow. When the water amount is sufficient, the gravity sensor senses a large water flow gravity signal, and the control device triggers the valve body to open, allowing the water flow to enter the system; and when the water amount is small, the gravity sensor feeds back a small gravity signal, and the control device closes the valve body, avoiding unnecessary water flow waste.

[0095] In addition, the utility model does not limit the specific setting position of the control device, and the person skilled in the art can arrange it on the photovoltaic module 1 or remotely, so the figure is not shown.

[0096] It should be understood that the utility model does not limit its application to the detailed structure and arrangement of the components proposed in the utility model. The utility model can have other embodiments and can be implemented and executed in various ways. The foregoing modifications fall within the scope of the utility model. It should be understood that the utility model disclosed and limited extends to all alternative combinations of two or more individual features mentioned in the text and / or drawings. All these different combinations constitute multiple alternative aspects of the utility model. The embodiments described in the utility model illustrate the best way known for implementing the utility model and will enable those skilled in the art to utilize the utility model.
