[0027] See also Figures 1 to 5 The present application provides a photovoltaic panel rainwater collection device, which is arranged at the bottom of the photovoltaic panel water guide groove, including: a lifting component 100, a cleaning component 200, a blocking component 300 and a water storage tank 400, the lifting component 100 includes a funnel-shaped shell 110, a filter plate 120 obliquely arranged in the shell 110 and a fixing member 130 arranged at the bottom of the shell 110, the bottom of the shell 110 extends into the fixing member 130, and the shell 110 can slide up and down along the inner wall of the fixing member 130; the cleaning component 200 is arranged below the filter plate 120 for cleaning the filter plate 120; the blocking component 300 is arranged in the shell 110 for blocking the bottom of the shell 110; the water storage tank 400 is arranged at the bottom of the fixing member 130, and a plurality of partitions 410 are arranged at the bottom of the water storage tank 400, and the height of the partitions 410 decreases successively, and the partitions 410 are used to filter the rainwater in the water storage tank 400.

[0028] Specifically, the solar photovoltaic panel is generally arranged at an angle, and rainwater slides down into the guide groove arranged at the bottom along the inclination angle of the solar photovoltaic panel. The water inlet of the shell 110 is arranged below the water outlet of the guide groove. The shell 110 is divided into a rain collecting part 111, a blocking part 112 and a rain outlet part 113 from top to bottom. The rain collecting part 111 has the largest inner diameter, the upper inner diameter of the blocking part 112 is the same as the inner diameter of the rain collecting part 111, and the lower inner diameter of the blocking part 112 is the same as the inner diameter of the rain outlet part 113. The inner diameter of the rain collecting part 111 is the same as that of the rain collecting part 112, the rain outlet part 113 extends into the fixing part 130, the blocking component 300 is arranged on the blocking part 112, the outer diameter of the blocking component 300 is 1.1 to 1.3 times the inner diameter of the rain collecting part 111, and is not larger than the inner diameter of the rain collecting part 111, the filter plate 120 is arranged on the rain collecting part 111 in an inclined manner along the flow direction of rainwater, and mud and gravel mixed in the rainwater slide down along the direction of the guide groove and slide down to the inclined angle of the filter plate 120 On one side of the filter plate 120, rainwater passes through the filter plate 120 and falls on the blocking portion 112 covered by the blocking component 300 by its own weight. When the amount of accumulated water reaches a threshold, the housing 110 slides downward along the inner wall of the fixing member 130, so that the blocking component 300 no longer covers the blocking portion 112, and the rainwater enters the storage box along the rain outlet 113. The storage box is provided with three partitions 410, and the partition away from one end of the fixing member 130 is The height of the plate 410 gradually decreases. It is more preferred to set three partitions 410 at the top and bottom of the storage box, and there is a gap between the top partition 410 and the bottom partition 410, and the horizontal projections of the top and bottom partitions 410 overlap by half. When the height of the frontmost rainwater exceeds the bottom partition 410, it flows into the next bottom partition 410 from the gap until the rainwater fills the end of the water tank 400 away from the fixing member 130.

[0029] The present application provides a technical solution adopted by a photovoltaic panel rainwater collection device that can achieve the following beneficial effects: when the rainfall is large, the rainwater is drained through the photovoltaic panel water guide groove to pass through the filter plate 120 for the first filtration to remove large debris such as mud and gravel; after the rainwater accumulates in the shell 110 and reaches a threshold, the shell 110 moves downward along the inner wall of the fixing member 130 to allow water to flow from both sides of the blocking component 300 into the water tank 400; the rainwater is filtered for a second time through the plurality of partitions 410 in the water tank 400, thereby achieving rainwater collection and filtration, and at the same time solving the problem that mud or other debris in the rainwater easily clogs the activated carbon layer in the recovery tank, causing rainwater to accumulate on the upper part of the recovery tank and overflow from the recovery tank.

[0030] In an optimized implementation scheme, in order to consider the cleaning efficiency, the cleaning assembly 200 includes a rotating member 210 and a vibrating member 220 , the rotating member 210 is hinged to the filter plate 120 , and the vibrating member 220 is fixedly connected to the rotating member 210 .

[0031] Rainwater passes through the filter plate 120, causing the rotating member 210 disposed below the filter plate 120 to rotate, driving the vibrating member 220 to vibrate and clean the filter plate 120, thereby causing the debris remaining or stuck on the filter plate 120 to move along the inclined slope of the filter plate 120, thereby achieving the cleaning of the filter plate 120.

[0032] In a specific embodiment, in order to improve the convenience of operation, the rotating member 210 includes a bearing 211, a rotating shaft 212 and a blade 213. The outer shaft of the bearing 211 is embedded in the center of the filter plate 120, the rotating shaft 212 is fixedly connected to the inner shaft of the bearing 211, and the blade 213 is fixedly connected to the rotating shaft 212.

[0033] The bearing 211 is horizontally arranged at the center of the filter plate 120, and the blade 213 is inclined up and down. Rainwater falls on the blade 213 and slides down along the inclination angle of the blade 213. The blade 213 is subjected to the downward impact force from the rainwater and the gravity of the rainwater, so that the blade 213 rotates to one side. By utilizing the power of the rainwater itself, the rotating part 210 is rotated, which reduces the layout of the motor, improves the utilization rate of the rainwater itself, and makes the operation simpler and more convenient.

[0034] In a preferred embodiment, in order to facilitate cleaning, the vibrating member 220 includes an end face cam 221, a first knocking lever 222 and a second knocking lever 223. The end face cam 221 is fixedly connected to the rotating shaft 212 and is located above the blade 213. The first knocking lever 222 and the second knocking lever 223 are both arranged above the end face cam 221 and are hinged to the rotating shaft 212.

[0035] Specifically, the surface of the end face cam 221 is provided with two sections of upward raised slopes, and the end face cam 221 is fixedly connected to the rotating shaft 212. The first knocking lever 222 and the second knocking lever 223 are set with different bends according to the slope of the filter plate 120, and the first knocking lever 222 and the second knocking lever 223 are both provided with through holes at one end close to the rotating shaft 212, and are both passed through by the rotating shaft 212. The first knocking lever 222 and the second knocking lever 223 are placed on the end face cam 221. When the end face cam 221 is driven to rotate by the rotating shaft 212, the first knocking lever 222 and the second knocking lever 223 do not rotate therewith. The raised slopes on the end face cam 221 respectively make the first knocking lever 222 and the second knocking lever 223 swing up and down, thereby touching the filter plate 120 and putting it in a vibrating state, so as to clean the filter plate 120, and the operation is simpler and more convenient.

[0036] In an optimized embodiment, in order to allow for the discharge of debris, a movable door 116 is provided on one side of the housing 110 , and the movable door 116 can be flipped 0° to 90° along the connection.

[0037] A discharge port is provided on the side wall of the shell 110 at the lowest point of the filter plate 120, and the discharge port is used to discharge debris. The movable door 116 is provided on the discharge port, and the movable door 116 is connected to the outer wall of the shell 110 by a return spring. When more and more debris accumulates at the lowest point of the filter plate 120, the debris pushes the movable door 116 to flip it upward. After all the debris is discharged, the movable door 116 is no longer pushed by the debris, and the movable door 116 returns to its original position and blocks the discharge port of the shell 110, thereby cleaning the debris.

[0038] In a preferred embodiment, in order to consider the continuity of use, a first limiting plate 114 is provided on the outer wall of the housing 110 , and a first spring 115 is provided between the first limiting plate 114 and the fixing member 130 .

[0039] On the outer wall of the rain outlet 113 of the shell 110, two first limiting plates 114 are symmetrically arranged, the top end of the fixing member 130 is arranged in an inverted L shape, the bottom end of the fixing member 130 extends into the water storage tank 400, and a first spring 115 with an inner diameter not less than the outer diameter of the rain outlet 113 of the shell 110 is arranged between the fixing member 130 and the first limiting plate 114. When the rainfall is heavy, the rainwater causes the shell 110 to move downward, and the first limiting plate 114 compresses the first spring 115. When the rainfall decreases or stops, when all the rainwater in the shell 110 is gone or a small amount of rainwater remains, the first spring 115 drives the first limiting plate 114 to return the shell 110, thereby realizing continuous use and making the operation simpler and more convenient.

[0040] In a detailed implementation scheme, the sealing assembly 300 includes a fixed top rod 310, a lifting rod 320 and a sealing block 330. The fixed top rod 310 is arranged at the bottom of the water tank 400 and coincides with the vertical center axis of the shell 110. The lifting rod 320 is slidably connected inside the shell 110 and coincides with the vertical projection of the fixed top rod 310. The sealing block 330 is fixedly connected to one end of the lifting rod 320 away from the fixed top rod 310, and is used to seal the water outlet of the shell 110.

[0041] Specifically, the vertical projections of the fixed top rod 310 and the lifting rod 320 coincide with the vertical projection of the central axis of the shell 110, and the sealing block 330 seals the shell 110 along the inner wall slope of the sealing portion 112 of the shell 110. The lifting rod 320 and the sealing block 330 move downward driven by the shell 110. When the lifting rod 320 contacts the fixed top rod 310, the shell 110 continues to move downward, so that the sealing block 330 no longer covers the sealing portion 112 of the shell 110, so that rainwater flows into the water storage tank 400 from the gap between the sealing block 330 and the inner wall of the shell 110, thereby solving the problem that the sealing block 330 cannot be opened and rainwater cannot enter the storage box, and the power of the entire process is provided by rainwater, and the operation is simpler and more convenient.

[0042] In order to consider stability, a preferred embodiment is provided in which two second limit plates 224 are arranged inside the housing 110, and the second limit plates 224 are penetrated by the lifting rod 320. A third limit plate 321 is arranged on the lifting rod 320, and the third limit plate 321 is located between the two second limit plates 224.

[0043] The two second limit plates 224 are fixed on the inner wall of the rain outlet part 113 of the shell 110, and the second limit plates 224 are each provided with a circular hole whose inner diameter is larger than that of the lifting rod 320, and are penetrated by the lifting rod 320. The length of the third limit plate 321 arranged on the lifting rod 320 is larger than the inner diameter of the circular hole on the second limit plate 224, and the position of the third limit plate 321 is between the two second limit plates 224. By providing the second limit plate 224 with a circular hole, the problem of the lifting rod 320 being offset when the shell 110 rises is solved, and the lifting rod 320 is prevented from shaking, resulting in the sealing block 330 being unable to open. At the same time, by providing the third limit plate 321, the problem of the lifting rod 320 exceeding the limit distance of the second limit plate 224 is solved.

[0044] In the implementation of further optimization, for the convenience of operation, a second spring 225 is provided between the second limit plate 224 near one end of the sealing block 330 and the third limit plate 321, and the second spring 225 is used to return the lifting rod 320 to its original position.

[0045] A second spring 225 is arranged between the third limiting plate 321 and the second limiting plate 224 at the top, and the second spring 225 has an outer diameter larger than the inner diameter of the circular hole on the second limiting plate 224 and an outer diameter smaller than the length of the second limiting plate 224 and the third limiting plate 321. When the shell 110 and the lifting rod 320 descend together, the second spring 225 is in a normal extended state, and the first spring 115 is compressed by the first limiting plate 114. When the lifting rod 320 contacts the fixed top rod 310, the third limiting plate 321 does not move, and the shell 110 and the second limiting plate 224 continue to descend, and the first spring 115 is still compressed. At this time, the second limiting plate 224 and the third limiting plate 321 squeeze the second spring 225 until the first spring 115 is in a normal extended state. 5 is compressed to a limit, and when all the rainwater in the shell 110 flows into the water storage tank 400, the second spring 225 drives the second limit plate 224 to move, so as to realize the return of the shell 110, thereby making the operation simpler and more convenient. At the same time, when the second spring 225 returns, the sealing block 330 just covers the blocking portion 112 of the shell 110. At this time, the first spring 115 continues to return, and the shell 110 drives the sealing block 330 to move upward until the first spring 115 returns. At this time, the lifting rod 320 is separated from the fixed top rod 310 and returns to the initial state. The whole operation provides kinetic energy for the rainwater. The first spring 115 and the second spring 225 return, and the operation is simpler and more convenient, and no human operation is required, thereby reducing labor intensity.

[0046] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
