Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel water collection technology, and specifically relates to a photovoltaic panel water collection device. Background Technology

[0002] Installing photovoltaic (PV) panels in the desert not only utilizes solar energy resources but also helps prevent wind erosion and sand fixation. Combined with straw checkerboard sand-fixing technology, it can effectively stabilize shifting sand dunes and prevent the spread of sandstorms. However, PV panels used in the desert for extended periods are affected by sand and dust, which significantly reduces their absorption efficiency of solar radiation. Therefore, cleaning is necessary. Cleaning the PV panels can increase their power generation efficiency by at least 5%. The usual cleaning method involves rinsing with water. To reduce water waste, the cleaning water is typically collected. Current methods involve designing a water collection tank under the PV panels to collect the cleaning water into a storage container. This reduces water waste and allows the collected water to irrigate desert plants, promoting ecological sand fixation. In existing photovoltaic (PV) panels, because the height of the lower edge frame is higher than the height of the panel itself, sand gradually accumulates along the lower edge until it reaches the panel. This sand accumulation obstructs the panel, affecting power generation efficiency. Furthermore, the sand-covered panel generates high temperatures (up to 80-100℃) due to reverse current, forming hot spots. Over time, this can lead to delamination, cracking, or even burning of the internal solar cells, shortening the panel's lifespan. Washing with water is insufficient to remove the sand accumulated along the lower edge of the panel. Using a water gun to clean the lower edge is also problematic because the sand accumulation zone is narrow and difficult to target, resulting in wasted water and prolonged cleaning time. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a photovoltaic panel water collection device that reduces sand accumulation at the lower edge of the photovoltaic panel while collecting water.

[0004] Technical Solution: To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A photovoltaic panel water collection device includes multiple sets of water collection components. Each water collection component includes a water collection tank, an intermediate pipe connected to the water collection tank, a drain pipe connected to the intermediate pipe, and a water collection bucket connected to the drain pipe. The water collection tank has a first notch corresponding to the lower end of the photovoltaic panel. The photovoltaic panel includes a power generation panel and a frame for supporting the power generation panel. The frame has a first groove. The water collection tank has a brush strip that contacts the photovoltaic panel and blocks the first groove.

[0006] Preferably, the water collection tank includes a first main body and a second main body rotatably connected to the first main body, and the brush strip is connected to the second main body.

[0007] Preferably, the second body is rotatably connected to the first body via a hinge.

[0008] Preferably, both the first body and the second body are arc-shaped plates, and the arcs of the first body and the second body on the same cross section are on the same circle.

[0009] Preferably, the brush strip includes multiple bristle groups that are pressed against the frame.

[0010] Preferably, a water collection space is formed in the water collection tank, and the second main body rotates relative to the first main body to switch the brush strip between a first position and a second position, wherein the brush strip is located inside the water collection space in the first position and outside the water collection space in the second position.

[0011] Preferably, there are two water collection tanks, which are respectively located on both sides of the intermediate pipe, and the intermediate pipe is provided with a second notch corresponding to the water collection tank.

[0012] Preferably, the water collection tank is inclined, and the connection between the water collection tank and the intermediate pipe is located at the lowest point.

[0013] Preferably, the photovoltaic panel is mounted on a photovoltaic support, and the water collection tank is connected to the photovoltaic support via a second support.

[0014] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention provides a solution by setting multiple brush strips on the water collection tank. The bristles of the brush strips press against the frame to cover the first groove on the frame, reducing the accumulation of sand in the first groove, preventing sand from accumulating on the photovoltaic panel, ensuring the power generation efficiency of the photovoltaic panel, and improving the service life of the photovoltaic panel.

[0016] 2. The brush bristle group is composed of multiple clumps of bristles. When it rains or washes the photovoltaic panel, the multiple bristle groups filter the water that slides off the photovoltaic panel. Large particles of sand and gravel are trapped on the brush strips, while small particles of sand and water enter the water collection space and finally enter the water collection bucket. The brush strips buffer the sliding water and reduce the impact force of the water entering the water collection space.

[0017] 3. The water collection tank includes a first body and a second body. The second body is rotatably connected to the first body via a hinge. The brush strip is set on the second body. The rotation of the second body causes the brush strip to switch between the first position and the second position. In the first position, the brush strip plays a role in shielding, filtering and buffering. In the second position, the sand and gravel on the brush strip can be cleaned by moving the bristles on the brush strip. Cleaning is convenient and quick.

[0018] 4. The brushes on the brush strip are elastic, ensuring that the brush strip works normally without affecting the second fastener structure at the bottom of the photovoltaic panel;

[0019] 5. Existing photovoltaic panels with grooved frames can be directly installed. The installation cost is extremely low and the installation is convenient. The brush strip covers the groove, and the water collection trough solves the problem of sand accumulation on the lower edge of the photovoltaic panel while collecting water, ensuring the cleanliness of the lower edge of the photovoltaic panel.

[0020] 6. When using a water gun to wash photovoltaic panels, the lack of sand accumulation at the lower edge of the panels improves washing efficiency and reduces washing time. Attached Figure Description

[0032] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0033] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a photovoltaic panel water collection device in this embodiment includes multiple sets of water collection components. Each water collection component includes a water collection trough 1, a middle pipe 2, a drain pipe 3, and a water collection bucket 4. There are two water collection troughs 1, and the positions of the water collection troughs 1 and photovoltaic panels 91 correspond to each other. Each water collection trough 1 corresponds to one photovoltaic panel 91. The photovoltaic panels 91 are mounted on photovoltaic brackets 92, and the photovoltaic brackets 92 are connected to foundation columns 93. Each photovoltaic panel 91 is connected to the foundation column 93 through a photovoltaic bracket 92. The lower end of the foundation column 93 is buried deep in the desert at a depth of 2-3 meters. The water collection trough 1 is connected to the photovoltaic bracket 92 through a second bracket 6. The second bracket 6 is detachably connected to the photovoltaic bracket 92 by bolts. There are multiple second brackets 6. The second brackets 6 support the water collection trough 1 from below, and the outer side of the water collection trough 1 is glued to the second bracket 6. The water collection trough 1 is strip-shaped and has a first notch 101, which corresponds to the lower end of the photovoltaic panel 91. The water collection trough 1 is hollow, forming a water collection space 102. The lower end of the photovoltaic panel 91 enters the water collection space 102 through the first notch 101. When it rains or the photovoltaic panel 91 is washed, the water sliding off the photovoltaic panel 91 enters the water collection space 102 through the first notch 101. One end of the water collection trough 1 is closed, and the other end is connected to the intermediate pipe 2. Two water collection troughs 1 are symmetrically distributed on both sides of the intermediate pipe 2. The intermediate pipe 2 is a T-shaped pipe, which includes a first pipe head 21, a second pipe head 22, and a drain pipe head 23. One water collection trough 1 is connected to the first pipe head 21. Another water collection tank 1 is connected to the second pipe head 22 by adhesive bonding. The first pipe head 21 and the second pipe head 22 also have a second notch 201, which corresponds to the photovoltaic panel 91, preventing the body of the intermediate pipe 2 from colliding with the photovoltaic panel 91 and affecting the installation of the intermediate pipe 2. The water collection tank 1 is tilted, with the connection point between the water collection tank 1 and the intermediate pipe 2 at the lowest point, allowing water to flow towards the intermediate pipe 2. Water sliding down from the photovoltaic panels 91 corresponding to the two water collection tanks 1 enters the intermediate pipe 2 from the water collection tank 1 and then falls from the drain pipe head 23. The drain pipe head 23 of the intermediate pipe 2 is connected to the drain pipe 3, which is connected to the water collection bucket 4. Water flows from the drain pipe 3 into the water collection bucket 4. Multiple sets of water collection components correspond to rows of photovoltaic panels 91.

[0034] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the photovoltaic panel 91 includes a power generation panel 911 and a frame 912 for supporting the power generation panel 911. The frame 912 has a first groove 901. The power generation panel 911 adopts the existing double-glass module, that is, the solar cell is encapsulated in the middle of two glass panels, which has higher corrosion resistance and mechanical strength and is suitable for strong wind and sand environment. The frame 912 can strengthen the overall structural strength. The photovoltaic panel 91 is pressed together with the adjacent photovoltaic panel 91 by a first fastener 94. The first fastener 94 includes a first pressure plate 941 and a first fastening bolt 942. The first pressure plate 941 has a first protrusion corresponding to the first groove 901. The first pressure plate 941 is pressed on the frame 912 of the two adjacent photovoltaic panels 91. The first fastening bolt 942 passes through the first pressure plate 941 and is threaded to the photovoltaic bracket 92, thereby fastening the two adjacent photovoltaic panels 91. The water collection tank 1 includes a first body 11 and a second body 12. Both the first body 11 and the second body 12 are arc-shaped plates. The arcs of the first body 11 and the second body 12 on the same cross section are on the same circle. The second body 12 is rotatably connected to the first body 11. The first body 11 is provided with a plurality of hinges 5. The plurality of hinges 5 are equally spaced on the first body 11. The second body 12 is rotatably connected to the first body 11 through the hinges 5. In this embodiment, the water collection tank 1 is cut from a PVC round pipe. A notch is cut into the PVC round pipe to form a first notch 101. A part of the pipe is cut open to form the second body 12. The hinges 5 are connected to the first body 11, and then the second body 12 is connected to the hinges 5. A brush strip 13 is provided on the water collection tank 1. The brush strip 13 is connected to the second main body 12. The brush strip 13 includes a base and a bristle group 131. The base is an arc-shaped plate. The bristle group 131 has multiple rows on the base. In this embodiment, there are five rows. Each bristle group 131 is composed of multiple bristle clusters. The multiple bristle clusters of each bristle group 131 are arranged in a row at equal intervals. The bristles 1301 are made of polymer materials, such as nylon 66. The length of a single bristle is 5-8cm. The bristles are cylindrical with a diameter of 0.5mm. Each bristle cluster is arranged in a rectangular shape by four rows and ten columns of bristles 1301. The base of the brush strip 13 is connected to the inner side of the second main body 12. The brush strip 13 contacts the photovoltaic panel 91 and blocks the first groove 901.The second main body 12 rotates relative to the first main body 11 to switch the brush strips 13 between a first position and a second position. In the first position, the brush strips 13 are located inside the water collection space 102; in the second position, they are located outside the water collection space 102. In the first position, the multiple brush strips 13 contact the lower end of the photovoltaic panel 91 and block the first groove 901. The multiple brush bristle groups 131 press against the frame 912. During sandstorms, the multiple brush bristle groups 131 prevent sand from accumulating in the first groove 901. After sandstorms, the photovoltaic panel 91 is washed. When it rains or the photovoltaic panel 91 is washed, water sliding off the photovoltaic panel 91 passes through the multiple brush bristle groups 131 and enters the water collection tank. The water collection space 102 within the photovoltaic panel 91 has a certain degree of elasticity in its bristles. The multiple bristle groups 131 buffer the water sliding down from the photovoltaic panel 91, preventing water from impacting into the water collection space 102 and then rushing out from the first opening 101 below the photovoltaic panel 91. At the same time, due to the obstruction of the multiple bristle groups 131, larger sand or pebbles are filtered out. Most of the larger sand (e.g., larger than 2mm) is blocked. After being blocked by the multiple bristle groups 131, only water and small-diameter sand enter the water collection space 102 and finally flow into the water collection tank 4. The small-diameter sand settles in the water collection tank 4, and the water in the water collection tank 4 can be used for drip irrigation of the plants under the panel. In the second position, since the brush strip 13 is outside the water collection space 102, the bristles on the brush strip 13 can be moved to remove sand and gravel, making cleaning convenient and quick.

[0035] like Figure 9 and Figure 10 As shown, when the lower end of the photovoltaic panel 91 is connected to the photovoltaic bracket 92 via the second fastener 95, the second fastener 95 includes a second pressure plate 951 and a second fastening bolt 952. The second pressure plate 951 is provided with a second protrusion 9511 corresponding to the first groove 901. In use, the second pressure plate is pressed onto the frame 912 at the lower end of the photovoltaic panel 91, and the second fastening bolt 952 is passed through the second pressure plate 951 and connected to the photovoltaic bracket 92, thereby strengthening the connection between the photovoltaic panel 91 and the photovoltaic bracket 92. Since the multi-bristle group 131 is elastic, the bristle group 131 will adaptively deform (bristle deformation) at the position corresponding to the second fastener 95, without affecting the original structure of the second fastener 95. Some existing new-structure photovoltaic panels have improved the design of the lower edge of the photovoltaic panel, making the lower edge frame flush with the power generation panel to reduce sand accumulation. However, there are still a large number of photovoltaic panels with grooved lower edge frames (the original grooved frame design is convenient for fixing). The water collection device of this embodiment can be directly installed on the existing photovoltaic panels with grooved frames to solve the problem of sand accumulation at the lower edge of the photovoltaic panel. Compared with replacing the photovoltaic panel or the frame, the water collection device of this embodiment has extremely low installation cost and is easy to install.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
