Description

Technical Field

[0001] This invention relates to the field of solar panel technology, and more specifically to an automatically cleanable solar power panel. Background Technology

[0002] During use, solar panels are usually fixed to a square frame to secure their position. In addition, protective plates are attached to the frame to protect the solar panels. In this way, the solar panels can work normally while being well protected.

[0003] However, since dust and impurities fall onto the protective plate in the air, it is usually necessary to clean the protective plate regularly in order to prevent excessive impurities from hindering the normal operation of the solar panel. In the existing technology, manual hand-held cleaning brushes are used to clean the dust on the surface of the solar panel. For a large number of solar panels, this cleaning method is inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide an automatically cleanable solar panel, solving the following technical problems:

[0005] Manually cleaning the surface of solar panels with a handheld brush is inefficient for a large number of solar panels.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A self-cleaning solar panel includes:

[0008] Base;

[0009] Solar panels are mounted on a rotating base.

[0010] The cleaning panels are arranged opposite to the solar panels;

[0012] A drain pipe, one end of which is connected to a cleaning plate;

[0013] A water conveying mechanism, which connects to the other end of the drain pipe;

[0014] Also includes:

[0015] The drive mechanism is located on one side of the solar panel and is connected to the cleaning plate to drive the cleaning plate to reciprocate along the side of the solar panel.

[0016] Preferably, the water conveying mechanism includes water storage tanks arranged opposite each other on both sides of the solar panel, and a cylinder body arranged opposite each other on the base. A piston is provided in the cylinder body, and the piston is connected to a pushing mechanism that drives it to reciprocate within the cylinder body. One end of the cylinder body is connected to the water storage tank through a water inlet pipe, and the other end is connected to the cleaning plate through a drain pipe.

[0017] Preferably, the water storage tank is further provided with a filter plate at the open end, and multiple sets of filter holes are evenly opened on the filter plate; wherein, the filter plate is slidably arranged in the water storage tank.

[0018] Preferably, the pushing mechanism includes a rack plate that slides relative to the base, and the rack plates on both sides are fixedly connected by supports; the base is also provided with an electric telescopic rod connected to the supports, wherein the piston is fixedly connected to a drive rod that slides on one side of the cylinder, and the rack plates on both sides are fixedly connected to the drive rod by push rods respectively.

[0019] Preferably, a support rod is fixedly installed on the back side of the solar panel, and the support rod is fixedly connected to a rotating shaft that is rotatably arranged on the base. Both ends of the rotating shaft are rotatably connected to limit seats arranged on the base. A first gear that meshes with a rack plate is arranged on the rotating shaft.

[0020] Preferably, the driving mechanism includes a screw that is rotatably arranged on one side of the solar panel, a nut that is helically sleeved on the screw, the nut being fixedly connected to the cleaning plate, and the screw being connected to a rotating shaft mechanism that drives its rotation.

[0021] Preferably, the rotating mechanism includes arc-shaped supports arranged opposite to each other on both sides of the solar panel. The arc-shaped supports are fixedly connected to the limiting seats through limiting frames. The arc-shaped supports have arc-shaped guide grooves. Arc-shaped racks are provided on the walls of the arc-shaped guide grooves. A second gear that meshes with the arc-shaped racks is rotatably arranged on one side of the solar panel. The second gear is connected to the screw drive through a belt and a pulley.

[0022] Preferably, a dust removal plate is also provided on one side of the cleaning plate, and a dust removal pad is pasted on the dust removal plate facing the solar panel, with the dust removal pad being attached to the solar panel.

[0023] The beneficial effects of this invention are:

[0024] (1) When the solar panel is cleaned, the water supply mechanism delivers water to the cleaning plate through the drain pipe, and then sprays and rinses the solar panel through the nozzles arranged on the cleaning plate. During the cleaning process, the cleaning plate is driven to slide along the side of the solar panel through the drive mechanism to achieve all-round cleaning of the surface of the solar panel.

[0025] (2) By installing a filter plate on the water storage tank, the present invention can filter impurities that fall into the water storage tank in the outdoor environment, thereby preventing impurities from entering the tank body through the water inlet pipe.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-2 As shown, the present invention is an automatically cleanable solar power panel, including a base 1 and a solar panel 2 rotatably arranged on the base 1. Two sets of cleaning plates 503 are arranged opposite each other on the solar panel 2, and multiple sets of nozzles 505 are evenly arranged on the cleaning plates 503 toward the solar panel 2.

[0038] The cleaning plate 503 is provided with a drain pipe 404, and the end of the drain pipe 404 away from the cleaning plate 503 is connected to the water conveying mechanism.

[0039] It also includes a drive mechanism arranged on one side of the solar panel 2. The drive mechanism is connected to the cleaning plate 503 to drive the cleaning plate 503 to reciprocate along the side of the solar panel 2. It can be explained that when cleaning the solar panel 2, the water supply mechanism delivers water to the cleaning plate 503 through the drain pipe 404, and then sprays and rinses the solar panel 2 through the nozzles 505 arranged on the cleaning plate 503. During the cleaning process, the drive mechanism drives the cleaning plate 503 to slide along the side of the solar panel 2 to achieve all-round cleaning of the surface of the solar panel 2.

[0040] Please see Figure 3The water conveying mechanism includes water storage tanks 4 arranged opposite each other on both sides of the solar panel 2. The water storage tanks 4 are fixedly connected to the base 1 via a frame 102. A cylinder 6 is also arranged opposite each other on the base 1. A piston 603 is installed inside the cylinder 6. The piston 603 is connected to a pushing mechanism that drives it to reciprocate within the cylinder 6. One end of the cylinder 6 is connected to the water storage tanks 4 via an inlet pipe 403, and the other end is connected to a cleaning plate 503 via a drain pipe 404. In one embodiment of the invention, a [missing information - likely a design feature] is provided between the inlet pipe 403 and the cylinder 6. There is a one-way valve for water inlet and a one-way valve for water outlet between the drain pipe 404 and the cylinder 6. It can be explained that the water storage tank 4 is set at a position higher than the cylinder 6. On rainy days, rainwater is collected through the water storage tank 4. Under the action of gravity, the water falls into the cylinder 6 through the water inlet pipe 403. Then, the piston 603 is driven by the drive mechanism to move in the cylinder 6 to squeeze the water in the cylinder 6 and discharge it to the cleaning plate 503 through the drain pipe 404. Finally, it is sprayed onto the solar panel 2 through the nozzle 505.

[0041] In addition, a filter plate 401 is provided at the open end of the water storage tank 4, and multiple sets of filter holes 402 are evenly opened on the filter plate 401. The filter plate 401 is slidably arranged in the water storage tank 4, and a handle 405 is provided at the end of the filter plate 401. In this embodiment, by arranging a filter plate 401 on the water storage tank 4, impurities that fall into the water storage tank 4 in the outdoor environment can be filtered, thereby preventing impurities from entering the cylinder 6 with the water inlet pipe 403. When the filter holes 402 on the filter plate 401 become blocked, the filter plate 401 can be pulled out from the water storage tank 4 by pulling the handle 405 to clean the filter plate 401.

[0042] Please see Figure 4 The pushing mechanism includes a rack plate 301 that slides relative to the base 1, and the rack plates 301 on both sides are fixedly connected by a support 306; the base 1 is also provided with an electric telescopic rod 3 connected to the support 306, wherein the piston 603 is fixedly connected to a drive rod 601 that is slidably arranged on one side of the cylinder 6, and the rack plates 301 on both sides are fixedly connected to the drive rod 601 by push rods 602 respectively; in one embodiment of the present invention, when the electric telescopic rod 3 is activated, the electric telescopic rod 3 drives the rack plate 301 to slide on the base 1 through the support 306, so that the rack plate 301 drives the piston 603 to move in the cylinder 6 through the push rod 602 and the drive rod 601;

[0043] Please see Figure 5In another embodiment of the present invention, a support rod 303 is fixedly installed on the back side of the solar panel 2. The support rod 303 is fixedly connected to a rotating shaft 302 rotatably arranged on the base 1. Both ends of the rotating shaft 302 are rotatably connected to a limiting seat 101 arranged on the base 1. A first gear 304 that meshes with a rack plate 301 is arranged on the rotating shaft 302. It can be explained that since the sun rises in the east and sets in the west, its trajectory is arc-shaped. In order to make full use of the light energy through the solar panel 2, the solar panel 2 faces the sun in the early morning. As the sun moves, the electric telescopic rod 3 pushes the rack plate 301 to move. During this process, the first gear 304 drives the rotating shaft 302 to rotate while meshing with the rack plate 301. The rotating shaft 302 then drives the support rod 303 to adjust the angle of the solar panel 2. As the sun sets, the solar panel 2 rotates to face the direction of the setting sun. Then, the electric telescopic rod 3 drives the rack plate 301 to reset, allowing the water in the water tank 4 to fall into the cylinder 6, so that the solar panel 2 can be cleaned during the day.

[0044] Please see Figure 6 Furthermore, the driving mechanism includes a screw 5 rotatably arranged on one side of the solar panel 2, a nut 501 is screwed on the screw 5, the nut 501 is fixedly connected to the cleaning plate 503, and the screw 5 is connected to the rotating shaft mechanism that drives its rotation. It can be explained that the screw 5 is driven to rotate by the rotating mechanism, and the nut 501 synchronously drives the cleaning plate 503 to move along the side of the solar panel 2 during the process of moving on the screw 5.

[0045] The rotating mechanism includes arc-shaped supports 104 arranged opposite to each other on both sides of the solar panel 2. The arc-shaped supports 104 are fixedly connected to the limiting seat 101 via a limiting frame 103. The arc-shaped supports 104 have arc-shaped guide grooves 105, and arc-shaped racks 106 are provided on the groove walls of the arc-shaped guide grooves 105. A second gear 307 that meshes with the arc-shaped rack 106 is rotatably arranged on one side of the solar panel 2. The second gear 307 is connected to the screw 5 via a belt 305 and a pulley. Specifically, during the rotation of the solar panel 2, it drives the second gear 307 to slide in the arc-shaped guide grooves 105. Since the second gear 307 meshes with the arc-shaped rack 106, the second gear 307 synchronously drives the screw 5 to rotate during its rotation via the belt 305 and the pulley.

[0046] As another real-time method according to an embodiment of the present invention, please refer to Figure 8The cleaning plate 503 is also provided with a dust removal plate 502 on one side. A dust removal pad 504 is attached to the dust removal plate 502 facing the solar panel 2. The dust removal pad 504 is attached to the solar panel 2. Thus, as the cleaning plate 503 moves back and forth on the solar panel 2, the dust removal plate 502 drives the dust removal pad 504 to move synchronously, so as to wipe away the dust on the solar panel 2 through the dust removal pad 504.

[0047] The working principle of this invention: Rainwater is collected through the water storage tank 4. Under the action of gravity, the water falls into the cylinder 6 through the inlet pipe 403. The electric telescopic rod 3 is activated, and the electric telescopic rod 3 drives the rack plate 301 to slide on the base 1 through the support 306. This causes the rack plate 301 to drive the piston 603 to move inside the cylinder 6 through the push rod 602 and the drive rod 601, so as to squeeze the water in the cylinder 6 and discharge it to the cleaning plate 503 through the drain pipe 404. Finally, it is sprayed onto the solar panel 2 through the nozzle 505. During the cleaning process, the cleaning plate 503 is driven by the drive mechanism to slide along the side of the solar panel 2, thereby achieving the cleaning of the solar panel. The solar panel 2 is cleaned in all directions. In the early morning, the solar panel 2 faces the direction of the rising sun. As the sun moves, the electric telescopic rod 3 pushes the rack plate 301 to move. The first gear 304 drives the rotating shaft 302 to rotate while meshing with the rack plate 301. The rotating shaft 302 then drives the support rod 303 to adjust the angle of the solar panel 2. As the sun sets, the solar panel 2 rotates to face the direction of the setting sun. Then, the electric telescopic rod 3 drives the rack plate 301 to reset, allowing the water in the water tank 4 to fall into the cylinder 6, so that the solar panel 2 can be cleaned during the day.
