The winding shaft is rotatably connected between the two connecting plates and is horizontally positioned. The end of the shading cloth away from the sliding strip is connected to the winding shaft. However, the locations where photovoltaic panels are installed are often remote and far from populated areas, making it difficult and untimely for staff to turn the motors on or off, resulting in reduced power generation efficiency of the photovoltaic panels. Summary of the Invention

[0003] Therefore, it is necessary to provide a rainproof cover device for photovoltaic panels to address the problem of difficulty and delay in the operation of turning the motor on or off by staff.

[0004] To achieve the above objectives, this application adopts the following approach:

One end of the traction rope is fixedly connected to the reversing gear, and the other end of the traction rope is fixedly connected to the end of the sliding member near the reversing gear. The sliding member is slidably connected to the photovoltaic panel and is capable of sliding along the width direction of the photovoltaic panel. The covering component includes a rotating shaft and a roller. The two ends of the rotating shaft are fixedly connected to both sides of the photovoltaic panel. The roller is rotatably connected to the rotating shaft and has a covering film on it. The other end of the covering film is fixedly connected to the sliding member.

[0007] Preferably, the transmission assembly includes a guide wheel, which is disposed at one end of the sliding member, and the traction rope is wrapped around the guide wheel one-quarter to one full turn.

[0008] Preferably, the transmission assembly further includes a speed-changing gear that meshes with the reversing gear, and the end of the traction rope near the reversing gear is fixedly connected to the speed-changing gear.

[0009] Preferably, the rainwater collection assembly includes a filter element and a water storage tank.

[0015] The technical solution adopted in this application can achieve the following beneficial effects:

[0016] This application provides a rainproof covering device for photovoltaic panels. The technical solution adopted can achieve the following beneficial effects: When the rainfall is heavy, the rainwater on the photovoltaic panel is collected into the rain collection component. The rain collection component slides downward to filter and store the rainwater. The downward movement of the rain collection component drives the reversing gear meshing with it to rotate, causing the traction rope to pull the sliding part to one end of the rain collection component, which causes the covering film to unfold and cover the photovoltaic panel. This prevents rainwater from contacting the photovoltaic panel, solving the problem of mud and other debris in the rainwater remaining on the photovoltaic panel and reducing its power generation efficiency. At the same time, when the rainfall gradually decreases or the rain stops, the weight of the rainwater collected by the filter is less than the threshold of the filter. The rain collection component slides upward back to its original position, the reversing gear rotates in the opposite direction, causing the sliding part to slide in the opposite direction back to its original position. The roller rotates in the opposite direction to roll up the covering film, allowing the photovoltaic panel to continue generating electricity. This solves the problem of photovoltaic panels being installed in remote areas and the difficulty and untimely operation of workers to start or stop the motor, making the operation simpler and more convenient.

[0023] Please see Figure 1 and Figure 2 This application provides a rainproof covering device for a photovoltaic panel, disposed at one end of a photovoltaic panel 10, comprising: a rain collection component 100, a transmission component, and a covering component 300. The rain collection component 100 is slidable up and down along the direction of gravity to filter and collect rainwater. The transmission component includes a reversing gear 210, a traction rope 220, and a sliding member. The reversing gear 210 meshes with the rain collection component 100, and one end of the traction rope 220 is fixedly connected to the reversing gear 210, while the other end of the traction rope 220... The sliding member is fixedly connected to one end of the sliding member near the reversing gear 210. The sliding member is slidably connected to the photovoltaic panel 10 and can slide along the width direction of the photovoltaic panel 10. The covering assembly 300 includes a rotating shaft 310 and a roller 320. The two ends of the rotating shaft 310 are fixedly connected to both sides of the photovoltaic panel 10. The roller 320 is rotatably connected to the rotating shaft 310, and a covering film 330 is provided on the roller 320. The other end of the covering film 330 is fixedly connected to the sliding member.

[0024] Specifically, the photovoltaic panel 10 is tilted at an angle of 0° to 90° with respect to the horizontal plane along its width. A water channel is provided along the length of the photovoltaic panel 10 (located on the side closer to the ground). The shading assembly 300 is located at the end furthest from the water channel. The rain collection assembly 100 is located below the outlet of the water channel. A rack is provided on the side of the rain collection assembly 100 near the reversing gear 210 (the length of the rack can be adjusted according to the width of the photovoltaic panel 10). A support rod is provided between the rain collection assembly 100 and the reversing gear 210, and the support rod is rotatably connected to the reversing gear 210 to increase the reversing speed. The reversing gear 210 is at the height of the rack, and the reversing gear 210 meshes with the rack. When rainwater begins to be stored in the rain collection assembly 100, the weight of the rainwater causes the housing to slide downward, thereby driving the reversing gear 210 to rotate clockwise, causing the traction rope 220 to wind up, and the cover assembly 300 to be pulled towards the end of the water channel away from the photovoltaic panel 10 (sliding along the width direction of the photovoltaic panel 10). When the rainfall decreases or the rainfall stops, the rainwater in the rain collection assembly 100 decreases, and the spring causes the rain collection assembly 100 to move upward and reset, thereby causing the reversing gear 210 to rotate counterclockwise, and the cover assembly 300 also returns to its original position. The sliding of the filter element 110 is achieved by the weight of the rainwater.

[0025] This application provides a rainproof covering device for photovoltaic panels. The technical solution achieves the following beneficial effects: when rainfall is heavy, rainwater on the photovoltaic panel 10 is collected into the rain collection component 100. The rain collection component 100 slides downwards, filtering and storing the rainwater. The downward movement of the rain collection component 100 drives the reversing gear 210, which in turn pulls the traction rope 220 towards one end of the rain collection component 100, causing the covering film 330 to unfold and cover the photovoltaic panel 10. This prevents rainwater from contacting the photovoltaic panel 10, thus solving the problem of rainwater leakage. The problem of mud, sand and other debris remaining on the photovoltaic panel 10 reduces its power generation efficiency. At the same time, when the rainfall gradually decreases or the rain stops, the weight of the rainwater collected by the filter element 110 is less than the threshold of the filter element 110. The filter element 110 slides upward back to its original position, the reversing gear 210 rotates in the opposite direction, causing the sliding element to slide in the opposite direction back to its original position, and the roller 320 rotates in the opposite direction to roll up the covering film 330, so that the photovoltaic panel 10 can continue to generate electricity. This solves the problem of the photovoltaic panel 10 being installed in remote areas and the difficulty and untimely operation of the operator to start or stop the motor, making the operation simpler and more convenient.

[0026] In a preferred embodiment, to improve power generation efficiency, the transmission assembly includes a guide wheel 240, which is disposed at one end of the water storage tank 120 near the sliding member, and the traction rope 220 is wrapped around the guide wheel 240 for one-quarter to one full turn.

[0027] Specifically, the shading assembly 300 is disposed at one end of the water channel of the photovoltaic panel 10. The guide wheel 240 is connected to the rain collection assembly 100 by a fixed rod, and the guide wheel 240 is rotatably connected to the fixed rod. The traction rope 220 wraps around the guide wheel 240 from the lower part upwards three-quarters of a turn, and the end of the traction rope 220 near the guide wheel 240 is fixedly connected to the bottom of the shading assembly 300. The connection between the guide wheel 240 and the traction rope 220 has sufficient space for the shading assembly to cover the water. The sliding distance of the cover assembly 300 is such that when one end of the traction rope 220 fixed to the reversing gear 210 is wound onto the reversing gear 210, the traction rope 220 pulls the cover assembly 300 from one end of the photovoltaic panel 10 water channel to the other end. The direction of the traction rope 220 is changed by the guide wheel 240. At the same time, the cover assembly 300 is set at one end of the photovoltaic panel 10 water channel to avoid the cover assembly 300 blocking sunlight and causing the photovoltaic panel 10 to have low efficiency.

[0028] In a specific implementation plan, for ease of operation, the transmission assembly further includes a speed-changing gear 250, which meshes with the reversing gear 210, and the end of the traction rope 220 near the reversing gear 210 is fixedly connected to the speed-changing gear 250.

[0029] Specifically, a variable speed gear 250 is provided below the reversing gear 210. The variable speed gear 250 is rotatably connected to the support rod connecting the reversing gear 210 and the rain collection assembly 100, and the variable speed gear 250 meshes with the reversing gear 210. One end of the variable speed gear 250 is provided with a winding wheel, and the traction rope 220 is wound counterclockwise around the winding wheel for winding the traction rope 220. The diameter of the variable speed gear 250 is smaller than the diameter of the reversing gear 210, and the variable speed gear 250 with the corresponding diameter is replaced according to the different widths of the photovoltaic panels 10. By reducing the diameter of the variable speed gear 250, the width and speed of winding the traction rope 220 are changed, making the operation simpler and more convenient.

[0030] In a preferred embodiment, the rain collection assembly 100 includes a filter element 110 and a water storage tank 120. The filter element 110 is disposed at the bottom of the water channel of the photovoltaic panel 10 and can slide up and down along the direction of gravity. The inlet of the water storage tank 120 is connected to the outlet of the filter element 110.

[0031] Specifically, the filter element 110 includes a housing, a filter plate, and a fixing member. A counterweight flap valve is provided at the bottom of the housing. The housing can slide up and down along the inner wall of the fixing member. The fixing member is located at the inlet of the water storage tank 120. A spring is provided between the fixing member and the housing. When rainwater collects in the housing and the weight reaches the threshold of the counterweight flap valve, the counterweight flap valve opens (the opening threshold is one-quarter of the maximum threshold of the counterweight flap valve, thereby ensuring that there is continuous rainwater in the rain collection assembly 100, keeping the counterweight flap valve in a continuously open state). Rainwater enters the water storage tank 120 from inside the housing along the fixing member. Within 0, the housing slides downwards. Conversely, when the rainwater decreases, the counterweight flap valve closes, and the spring drives the housing to reset, causing the reversing gear 210 to reverse, thereby realizing the up-and-down sliding of the rainwater collection component 100. The entire process uses the weight of the rainwater to achieve the up-and-down sliding of the rainwater collection component 100, reducing the need for mechanical equipment and solving the problem of untimely motor opening or closing. At the same time, a drain outlet is provided on one side of the water storage tank 120. When rainwater enters the water storage tank 120, it flows out from the drain outlet, solving the problem that excessive water accumulation in the water storage tank 120 prevents the rainwater collection component 100 from sliding up and down in the vertical direction.

[0032] In a better implementation, to improve stability, the sliding member includes a support frame 231 and a movable frame 232. One end of the support frame 231 is fixedly connected to the water storage tank 120, and the movable frame 232 is slidably connected to the support frame 231. The end of the movable frame 232 near the reversing gear 210 is connected to the traction rope 220.

[0033] Specifically, both the support frame 231 and the movable frame 232 can be steel pipe supports. The bottom of the support frame 231 is fixedly connected to the top of the water storage tank 120. The other end of the support frame 231 is provided with a U-shaped channel through which the movable frame 232 passes. Both ends of the movable frame 232 are provided with baffles to prevent it from detaching. The movable frame 232 is pulled by the traction rope 220 to reciprocate within the channel of the support frame 231, thereby enabling the spreading and rolling of the covering film 330. Furthermore, the connection between the support frame 231 and the water storage tank 120 makes the sliding more stable, solving the problem of the photovoltaic panel 10 shaking when the sliding component moves, thus improving the overall stability.

[0034] In one embodiment, for ease of reset, a spring 234 is provided on the support frame 231, and the other end of the spring 234 is fixedly connected to the movable frame 232 for resetting the movable frame 232.

[0035] A spring 234 is provided at the end of the channel of the support frame 231 away from the guide wheel 240. The other end of the spring 234 is connected to the end of the movable frame 232 away from the guide wheel 240. When the spring 234 is in normal relaxation, one end of the movable frame 232 connected to the traction rope 220 extends out of one end of the water guide channel of the photovoltaic panel 10. When the traction rope 220 is pulled and wound onto the winding wheel 260 coaxially arranged with the transmission gear 250 (the diameter of the winding wheel 260 depends on the photovoltaic panel...), (Adjusting the width of 10), the movable frame 232 moves to the end away from the water channel of the photovoltaic panel 10, and the spring 234 is compressed until the photovoltaic panel 10 is completely covered by the covering film 330. When the end of the traction rope 220 that is wound up is gradually released, the spring 234 returns to its original position, driving the movable frame 232 from the end away from the water channel of the photovoltaic panel 10 to the end of the water channel of the photovoltaic panel 10. By setting the spring 234, the reset of the movable frame 232 is achieved, making the operation simpler and more convenient.

[0036] In the optimized design, to improve service life, friction wheels 233 are provided on the movable frame 232. The friction wheels 233 are rotatably connected to the movable frame 232 and slidably connected to both sides of the photovoltaic panel 10. The friction wheels 233 are located at both ends of the movable frame 232 and are slidably connected to both sides of the photovoltaic panel 10. The friction wheels 233 are made of flexible material and are horizontally arranged. A fixed shaft is provided in the middle of the friction wheel 233. The fixed shaft is fixedly connected to the movable frame 232 and rotatably connected to the friction wheel 233. When the movable frame 232 reciprocates, the friction wheels 233 slide on the sidewalls of the photovoltaic panel 10, making the sliding of the movable frame 232 more convenient. Furthermore, the flexible friction wheels 233 prevent damage to the photovoltaic panel 10, thereby improving its service life.

[0037] In a preferred embodiment, to improve covering efficiency, the covering assembly 300 includes a tension rod 350, which is fixedly connected to one end of the covering film 330 away from the roller 320, and the two ends of the tension rod 350 are respectively fixedly connected to the sliding member.

[0038] Specifically, the two ends of the tension rod 350 are fixedly connected to the fixed shaft in the middle of the friction wheel 233. The tension rod 350 moves with the movement of the moving frame 232. The tension rod 350 is provided with a clamp for fixing the covering film 330. One end of the covering film 330 extends out of the tension rod 350 and covers one end of the tension rod 350. When the tension rod 350 moves from one end of the water channel of the photovoltaic panel 10 to the other end of the photovoltaic panel 10, the covering film 330 covers the photovoltaic panel 10. By setting the tension rod 350, the covering of the covering film 330 is made simpler and more convenient. At the same time, by having the tension rod 350 extend out of the covering film 330, the problem of rainwater entering between the covering film 330 and the photovoltaic panel 10 is solved.

[0039] In a further embodiment, to improve ease of operation, the covering assembly 300 also includes a return spring 340, which is penetrated by the rotating shaft 310, and the other end of the return spring 340 is fixedly connected to the inner wall of the roller 320.

[0040] One end of the reset spring 340 is fixedly connected to the rotating shaft 310. When the roller 320 rotates the covering film 330 to cover the photovoltaic panel 10, the reset spring 340 is compressed. Conversely, when the covering film 330 needs to be rolled up, the reset spring 340 resets and drives the covering film 330 to be rolled up by the roller 320, thereby making the operation simpler and more convenient.

[0041] To improve service life, an optimized solution is provided in which the covering component 300 further includes a housing 360, which covers the roller 320 to protect the covering film 330.

[0042] Specifically, the box 360 is detachably connected to the end of the photovoltaic panel 10 that has a water guide groove, and the top of the box 360 is set as a slope with the same gradient as the photovoltaic panel 10. One side of the box 360 is hollowed out for the movement of the tension rod 350. When the rainfall is small or there is no rainfall, the tension rod 350 is inside the box 360. When the rainfall is large, the moving frame 232 drives the tension rod 350 to move out from the hollow side of the box 360. By setting the box 360 to protect the tension rod 350 and the covering film 330, the problem of the covering film 330 being exposed to the outside for a long time and thus reducing the service life of the covering film 330 is solved, while avoiding damage to the covering film 330 by foreign objects is also prevented.

[0043] The embodiments described above merely illustrate the device layout of this application. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make several adjustments and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
