Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic panel cleaning technology, specifically, it relates to a solar photovoltaic panel cleaning device. Background Technology

[0002] Solar power generation equipment is often installed outdoors, where there is frequent wind and sand. Over time, dust and other impurities will gradually accumulate on the surface of the solar photovoltaic panels, affecting their absorption of solar energy and consequently impacting the power generation efficiency of the equipment. This can also easily cause malfunctions in the solar photovoltaic panels. Therefore, it is necessary to clean the solar power generation equipment regularly or irregularly.

[0003] Chinese utility model patent CN222366241U discloses a photovoltaic panel cleaning device. During operation, a movable wheel drives a cleaning roller to rotate, achieving the cleaning process. The unidirectional bearing and gravity block ensure the cleaning roller rotates in one direction, continuously pushing dust downwards. Simultaneously, a crank rod moves a movable plate up and down within a cavity, enabling air blowing during cleaning to remove dust from the top of the photovoltaic panel, thus effectively improving the cleaning effect.

[0004] Although the device can drive the cleaning roller to rotate via the moving wheel, the moving wheel and the cleaning roller rotate in the same direction, which reduces the friction between the cleaning roller and the photovoltaic panel surface, resulting in poor cleaning effect. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the device can drive the cleaning roller to rotate via the moving wheel, the moving wheel and the cleaning roller rotate in the same direction, resulting in low friction between the cleaning roller and the photovoltaic panel surface and poor cleaning effect, the present invention adopts the following technical solution.

[0007] A solar photovoltaic panel cleaning device includes a U-shaped mounting frame with its opening facing downwards. Movable wheels are rotatably connected to both sides of the U-shaped mounting frame, and a cleaning roller is rotatably connected inside the U-shaped mounting frame. A mounting bracket is fixedly connected to the upper end of the U-shaped mounting frame, and a telescopic handle is rotatably connected to the mounting bracket. A reversing component is installed between the movable wheels and the cleaning roller, which causes the movable wheels and the cleaning roller to rotate in opposite directions.

[0008] Preferably, the reversing component is equipped with a one-way rotation component, which causes the moving wheel and the cleaning roller to rotate in opposite directions when the device moves downward from the photovoltaic panel, and the cleaning roller does not rotate while the moving wheel rotates when the device moves upward from the photovoltaic panel.

[0009] Preferably, a flushing assembly is installed on the U-shaped frame, which can flush the surface of the photovoltaic panel.

[0010] Preferably, a water scraper assembly is installed on the U-shaped mounting frame, which can scrape water off the surface of the photovoltaic panel.

[0011] Preferably, the flushing assembly includes a water spray bend, a connecting hose, and a cavity. Multiple water spray bends are provided on the outer wall of the mounting U-shaped frame near the extension direction of the telescopic handle. A cavity is provided on the mounting U-shaped frame, and each water spray bend communicates with the cavity. A connecting hose is detachably connected to the upper end of the mounting U-shaped frame, and the connecting hose communicates with the cavity. A limit plate is fixedly connected to the end of the telescopic handle, and the connecting hose passes through the limit plate and is connected to the water pump.

[0012] Preferably, the wiper assembly includes a wiper blade, a connecting plate, and a third rotating shaft. A mounting groove is provided on the outer wall of the mounting U-shaped bracket away from the telescopic handle. The third rotating shaft is rotatably connected to the inner torsion spring of the mounting groove. The connecting plate is fixedly connected to the outer wall of the third rotating shaft. The wiper blade is fixedly connected to the end of the connecting plate. The third rotating shaft causes the wiper blade to have a downward rotating force.

[0013] Preferably, the reversing assembly includes a first rotating shaft, a first meshing gear, a second rotating shaft, and a second meshing gear. The outer wall of each moving wheel is fixedly connected to the first rotating shaft. The first rotating shaft passes through the vertical side of the mounting U-shaped frame and is rotatably connected. The outer wall of each first rotating shaft is provided with a first meshing gear. The two ends of the cleaning roller are provided with second rotating shafts. The outer wall of the second rotating shaft is provided with a second meshing gear. The second meshing gear meshes with the first meshing gear.

[0014] Preferably, the unidirectional rotation assembly includes a mounting chamber, ratchet teeth, ratchet pawls, and a limiting plate. The second meshing gear and the first rotating shaft are provided with mounting chambers inside each other. The second meshing gear is fixedly connected to the outer wall of the cleaning roller. The first rotating shaft and the second meshing gear are provided with mounting chambers inside each other. The second rotating shaft and the first rotating shaft are inserted into the interior of the mounting chambers. Multiple ratchet teeth are fixedly connected to the inner wall of the mounting chambers. The outer walls of the second rotating shaft and the first rotating shaft are rotatably connected to ratchet pawls by torsion springs. The outer walls of the second rotating shaft and the first rotating shaft near the ratchet pawls are fixedly connected with limiting plates. The limiting plates and ratchet teeth inside the second meshing gear and the first rotating shaft are arranged in opposite directions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Through the set reversing component, the first meshing gear and the second meshing gear mesh, so that when the device moves from top to bottom, the rotating wheel drives the cleaning roller to rotate in the opposite direction, thereby sweeping the dust on the photovoltaic panel downward, increasing the friction between the cleaning roller and the surface of the photovoltaic panel, and making the cleaning effect better.

[0017] 2. With the unidirectional rotation component, when the device moves downward from the photovoltaic panel, the ratchet pawl inside the first meshing gear engages with the ratchet teeth, causing the first meshing gear to rotate and drive the second meshing gear to rotate. At this time, the ratchet pawl inside the second meshing gear rotates along with the ratchet teeth, thus enabling the cleaning roller and the moving wheel to rotate in opposite directions. When the device moves upward from below the photovoltaic panel, the ratchet pawl inside the first meshing gear rotates along with the ratchet teeth, and the ratchet pawl inside the second meshing gear engages with the ratchet teeth, thereby enabling the moving wheel to rotate while the cleaning roller does not rotate, thus preventing dust from being swept to the bottom by the cleaning roller when the device moves upward.

[0018] 3. Through the set flushing components, the water pump pressurizes and delivers water to the inside of the cavity through the connecting hose, so that the water can be sprayed onto the surface of the photovoltaic panel through the water spray bend to flush the surface of the photovoltaic panel.

[0019] 4. With the addition of a squeegee assembly, the squeegee is in close contact with the surface of the photovoltaic panel, thus removing water from the surface of the photovoltaic panel when the device is moved from top to bottom, preventing water stains from affecting the power generation of the photovoltaic panel.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0031] like Figure 1The diagram shown is a schematic representation of a solar photovoltaic panel cleaning device according to a preferred embodiment of the present invention. This embodiment of the solar photovoltaic panel cleaning device includes a U-shaped mounting frame 100 with its opening facing downwards. Moving wheels 101 are rotatably connected to both sides of the U-shaped mounting frame 100. A cleaning roller 200 is rotatably connected inside the U-shaped mounting frame 100. A mounting bracket 103 is fixedly connected to the upper end of the U-shaped mounting frame 100. A telescopic handle 104 is rotatably connected to the mounting bracket 103. Multiple water spray bends 102 are provided on the outer wall of the U-shaped mounting frame 100 near the extension direction of the telescopic handle 104. A cavity is provided on the U-shaped mounting frame 100, and each water spray bend 102 communicates with the cavity. The upper end of the U-shaped frame 100 is detachably connected to a connecting hose 105, which communicates with the cavity. The end of the telescopic handle 104 is fixedly connected to a limiting plate 106. The connecting hose 105 passes through the limiting plate 106 and is connected to a water pump. In this embodiment, the telescopic handle 104 is convenient for cleaning personnel to hold and adjust the length. The water pump pressurizes and delivers water to the cavity through the connecting hose 105, which in turn allows the water to be sprayed onto the surface of the photovoltaic panel through the spray bend 102 to rinse the surface of the photovoltaic panel. The moving wheel 101 contacts the surface of the photovoltaic panel and moves up and down. The moving wheel 101 rotates and causes the cleaning roller 200 to rotate to clean the surface of the photovoltaic panel.

[0032] It is worth noting that the aforementioned water spray bend 102, connecting hose 105, and cavity are the flushing components in this embodiment. The flushing components include, but are not limited to, the water spray bend 102, connecting hose 105, and cavity. Any component that can flush the surface of the photovoltaic panel can be used in this embodiment.

[0033] like Figure 2 As shown, this is a schematic diagram of the wiper assembly structure in this embodiment. The outer wall of the U-shaped frame 100 away from the telescopic handle 104 is provided with a mounting groove. The inner torsion spring of the mounting groove is rotatably connected to a third rotating shaft 302. A connecting plate 301 is fixedly connected to the outer wall of the third rotating shaft 302. A wiper blade 300 is fixedly connected to the end of the connecting plate 301. The third rotating shaft 302 causes the wiper blade 300 to have a downward rotating force. In this embodiment, by having the wiper blade 300 closely adhere to the surface of the photovoltaic panel, water on the surface of the photovoltaic panel can be wiped away when the device is moved from top to bottom, avoiding water stains that may affect the power generation of the photovoltaic panel.

[0034] It is worth noting that the aforementioned wiper blade 300, connecting plate 301, and third rotating shaft 302 are the wiper components in this embodiment. The wiper components include, but are not limited to, the wiper blade 300, connecting plate 301, and third rotating shaft 302. Any component that can wipe water off the surface of the photovoltaic panel can be used in this embodiment.

[0035] like Figure 3As shown, this is a schematic diagram of the reversing component structure in this embodiment. Each moving wheel 101 has a first rotating shaft 201 fixedly connected to its outer wall. The first rotating shaft 201 passes through the vertical side of the mounting U-shaped frame 100 and is rotatably connected. Each first rotating shaft 201 has a first meshing gear 202 on its outer wall. The cleaning roller 200 has a second rotating shaft 203 at both ends. The second rotating shaft 203 has a second meshing gear 204 on its outer wall. The second meshing gear 204 meshes with the first meshing gear 202. In this embodiment, the meshing of the first meshing gear 202 and the second meshing gear 204 causes the moving wheel 101 to rotate and drive the cleaning roller 200 to rotate in the opposite direction when the device moves from top to bottom. This sweeps the dust on the photovoltaic panel downwards, increasing the friction between the cleaning roller 200 and the surface of the photovoltaic panel, resulting in a better cleaning effect.

[0036] It is worth noting that the first rotating shaft 201, the first meshing gear 202, the second rotating shaft 203, and the second meshing gear 204 mentioned above are the reversing components in this embodiment. The reversing components include, but are not limited to, the first rotating shaft 201, the first meshing gear 202, the second rotating shaft 203, and the second meshing gear 204. Any component that can make the moving wheel 101 rotate in the opposite direction to the cleaning roller 200 can be applied to this embodiment.

[0037] like Figure 4As shown, this is a schematic diagram of the unidirectional rotation component structure in this embodiment. The second meshing gear 204 and the first rotating shaft 201 have an installation chamber 205 inside. The second meshing gear 204 is fixedly connected to the outer wall of the cleaning roller 200. The first rotating shaft 201 and the second meshing gear 204 have an installation chamber 205 inside. The second rotating shaft 203 and the first rotating shaft 201 are inserted into the installation chamber 205. Multiple ratchet teeth 206 are fixedly connected to the inner wall of the installation chamber 205. A ratchet pawl 207 is rotatably connected to the outer wall of the second rotating shaft 203 and the first rotating shaft 201 via a torsion spring. A limiting plate 208 is fixedly connected to the outer wall of the second rotating shaft 203 and the first rotating shaft 201 near the ratchet pawl 207. The limiting plate 208 and ratchet teeth 206 inside the second meshing gear 204 and the first rotating shaft 201 are designed... In this embodiment, when the device moves downward from the photovoltaic panel, the ratchet pawl 207 inside the first meshing gear 202 engages with the ratchet teeth 206, causing the first meshing gear 202 to rotate and drive the second meshing gear 204 to rotate. At this time, the ratchet pawl 207 inside the second meshing gear 204 rotates along with the ratchet teeth 206, thereby enabling the cleaning roller 200 and the moving wheel 101 to rotate in opposite directions. When the device moves upward from the bottom of the photovoltaic panel, the ratchet pawl 207 inside the first meshing gear 202 rotates along with the ratchet teeth 206, and the ratchet pawl 207 inside the second meshing gear 204 engages with the ratchet teeth 206, thereby enabling the moving wheel 101 to rotate while the cleaning roller 200 does not rotate, thus preventing dust from being swept downward by the cleaning roller 200 when the device moves upward.

[0038] It is worth noting that the aforementioned mounting chamber 205, ratchet teeth 206, ratchet pawls 207, and limiting plate 208 are unidirectional rotation components in this embodiment. The unidirectional rotation components include, but are not limited to, the mounting chamber 205, ratchet teeth 206, ratchet pawls 207, and limiting plate 208. As long as the device can make the moving wheel 101 and the cleaning roller 200 rotate in opposite directions when the device moves downward from the photovoltaic panel, and the cleaning roller 200 does not rotate and the moving wheel 101 rotates when the device moves upward from the photovoltaic panel, the moving wheel 101 rotates.

[0039] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
