Description

Technical Field

[0001] The present application relates to the technical field of solar photovoltaic panel cleaning, and in particular to a solar photovoltaic panel surface cleaning device. Background Art

[0002] At present, solar photovoltaic panels, also known as solar panels, are energy conversion devices that directly convert solar energy into electrical energy. When sunlight shines on the surface of photovoltaic panels, photons will interact with atoms or electrons in the photovoltaic material. If the energy of the photons is large enough, it can excite the electrons in the atoms to form free electrons, which in turn generates current in the material and realizes the conversion of light energy into electrical energy.

[0003] In related technologies, in order to enhance the light absorption and scattering capabilities of the surface of solar photovoltaic panels and improve the absorption rate of sunlight, a nano-coating is usually sprayed on the surface of the solar photovoltaic panels. Before spraying the nano-coating, the solar photovoltaic panels are cleaned with a roller brush.

[0004] Regarding the above-mentioned related technologies, dust will be generated during the cleaning process of the roller brush and some bristles will fall off, thereby affecting the spraying effect of the nano-coating of the solar photovoltaic panel. Utility Model Content

[0005] In order to improve the cleaning effect of solar photovoltaic panels before spraying nano-coating, the present application provides a solar photovoltaic panel surface cleaning device.

[0006] The present application provides a solar photovoltaic panel surface cleaning device that adopts the following technical solutions:

[0007] A solar photovoltaic panel surface cleaning device includes a support frame, a cleaning roller brush is rotatably connected to the support frame, an electrostatic adsorption component is provided on the side wall of the cleaning roller brush, the electrostatic adsorption component is used to adsorb dust on the surface of the solar photovoltaic panel, the electrostatic adsorption component includes an adsorption plate, the adsorption plate is connected to the side wall of the support frame close to the cleaning roller brush, and the adsorption plate is arranged parallel to the cleaning roller brush.

[0008] By adopting the above technical solution, during the process of cleaning the solar photovoltaic panels, the dust on the support frame is brushed away by the cleaning roller brush. The dust will be lifted up during the brushing process, and the adsorption plate will be charged with static electricity, so the dust can be effectively adsorbed by the adsorption plate, thereby effectively cleaning the solar photovoltaic panels. The electrostatic dust suction can quickly adsorb dust and particles, speed up work efficiency, and reduce impact and friction damage to the surface of the solar photovoltaic panels.

[0009] Preferably, the electrostatic adsorption component further includes a friction roller, which is arranged close to the end face of the adsorption plate and abuts against the end face of the adsorption plate, and the friction roller is rotatably connected to the support frame, and a plurality of friction rollers are provided.

[0010] By adopting the above technical solution, the friction roller rotates and rubs against the adsorption plate, so that the adsorption plate can generate static electricity, so that the adsorption plate can effectively adsorb dust on the solar photovoltaic panel, thereby reducing the impact or damage to the solar photovoltaic panel during the cleaning process, saving cleaning costs, and no harmful by-products are produced during the electrostatic dust collection process, which is environmentally friendly.

[0011] Preferably, a plurality of plastic strips are evenly arranged on the circumferential surface of the friction roller.

[0012] By adopting the above technical solution, the friction between several plastic strips and the adsorption plate can produce a stronger electrostatic effect, making the electron transfer more significant, accelerating the efficiency of static electricity generation, thereby enhancing the intensity and stability of static electricity, and more effectively removing dust and stains on the surface of the solar photovoltaic panel, thereby improving the cleaning quality and efficiency.

[0013] Preferably, a dust collecting shell is provided on the support frame, and the friction roller, the adsorption plate and the cleaning roller brush are all installed inside the dust collecting shell. A dust collecting port is opened on the dust collecting shell along the length direction of the cleaning roller brush, and the dust collecting port is used to collect dust.

[0014] By adopting the above technical solution, in the process of electrostatic adsorption of dust, the dust on the surface of the solar photovoltaic panel is lifted up by the cleaning roller brush, enters the dust collecting shell through the dust collecting port, and is adsorbed by the adsorption plate through static electricity. The adsorption plate is located in the dust collecting shell, which can enhance the adsorption and collection effect of dust. The dust collecting shell provides further guarantee for the dust collection on the adsorption plate. When the dust on the adsorption plate falls, it will fall directly into the dust collecting shell, reducing the situation of dust falling back on the solar photovoltaic panel, thereby improving the cleaning effect to a certain extent, reducing the repeated cleaning process, and improving cleaning efficiency.

[0015] Preferably, a plurality of dust-attaching grooves are evenly arranged on the side wall of the adsorption plate close to the cleaning roller brush.

[0016] By adopting the above technical solution, the dust-attaching grooves effectively increase the surface roughness of the adsorption plate, thereby effectively increasing the surface area of ​​the adsorption plate, making the adsorption surface larger, and more effectively adsorbing the dust on the solar photovoltaic panel. Increasing the surface roughness of the adsorption plate can provide more adsorption points, making it easier for dust to be adsorbed and fixed on the adsorption plate, thereby improving the dust removal efficiency. At the same time, the rough surface can increase the friction between the adsorption plate and the dust particles, making it easier to capture tiny particles, preventing dust particles from easily falling off under the action of wind or other external forces, and extending the service life of the adsorption plate.

[0017] Preferably, a photovoltaic panel connection assembly is provided on the support frame, and the photovoltaic panel connection assembly is used to be connected to the photovoltaic panel, and the support frame is slidably connected to the photovoltaic panel connection assembly.

[0018] By adopting the above technical solution, during the process of cleaning the solar photovoltaic panel, the support frame is connected to the solar photovoltaic panel through the photovoltaic panel connecting assembly, and the support frame slides on the photovoltaic panel connecting assembly, so that the support frame can drive the cleaning roller brush and the electrostatic adsorption assembly to slide and clean the solar photovoltaic panel, thereby comprehensively cleaning the solar photovoltaic panel.

[0019] Preferably, the photovoltaic panel connection assembly includes a fixing rod, which is arranged perpendicular to the length direction of the cleaning roller brush. Two fixing rods are symmetrically arranged along the midpoint of the cleaning roller brush. A fixing clamp is provided at the end of the fixing rod, and the fixing clamp is used to clamp the solar photovoltaic panel.

[0020] By adopting the above technical solution, during the cleaning process, the edge of the solar photovoltaic panel is stably clamped by the fixing clamp, and two fixing rods are symmetrically arranged to increase the stability during the cleaning process and reduce the shaking of the support frame during the cleaning process, thereby reducing unnecessary friction between the solar photovoltaic panel and the cleaning roller brush, so that the cleaning roller brush lightly wipes the surface of the solar photovoltaic panel, effectively cleaning the surface of the solar photovoltaic panel.

[0021] Preferably, a sliding groove is provided on the side wall of the fixed rod near the cleaning roller brush along the length direction of the fixed rod, and the end of the support frame near the fixed rod is rotatably connected to a sliding wheel, which is located in the sliding groove and can slide in the sliding groove.

[0022] By adopting the above technical solution, the sliding wheel slides in the sliding groove, so that the support frame moves on the solar photovoltaic panel. This structure is simple and compact, which increases the stability of the support frame to a certain extent, thereby increasing the cleaning stability and reducing the vibration of the electrostatic adsorption component. Further, the adsorption of dust by the adsorption plate is more stable, reducing the possibility of dust falling.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The present application provides a cleaning roller brush, an adsorption plate and a friction roller. In the process of cleaning the solar photovoltaic panel, the cleaning roller brush rolls to brush the dust on the support frame. The dust is raised in the process of brushing. The adsorption plate is charged with static electricity, and the dust can be effectively adsorbed by the adsorption plate, thereby effectively cleaning the solar photovoltaic panel. The electrostatic dust suction can quickly adsorb dust and particles, speeding up work efficiency and reducing impact and friction damage to the surface of the solar photovoltaic panel. The friction roller rotates and rubs against the adsorption plate, thereby generating static electricity on the adsorption plate, which enables the adsorption plate to effectively adsorb dust on the solar photovoltaic panel, thereby reducing impact or damage to the solar photovoltaic panel during the cleaning process, saving cleaning costs, and no harmful byproducts are produced in the process of electrostatic dust suction, which is environmentally friendly.

[0025] 2. The present application sets a dust collecting shell. During the process of electrostatic adsorption of dust, the dust on the surface of the solar photovoltaic panel is lifted up by the cleaning roller brush and enters the dust collecting shell through the dust collecting port. It is adsorbed by the adsorption plate through static electricity. The adsorption plate is located inside the dust collecting shell, which can enhance the adsorption and collection effect of the dust. The dust collecting shell provides further protection for the dust collection on the adsorption plate. When the dust on the adsorption plate falls, it will fall directly into the dust collecting shell, reducing the situation of dust falling back onto the solar photovoltaic panel, thereby improving the cleaning effect to a certain extent, reducing the repeated cleaning process, and improving the cleaning efficiency.

[0026] 3. This application sets up a photovoltaic panel connection component. During the process of cleaning the solar photovoltaic panel, the support frame is connected to the solar photovoltaic panel through the photovoltaic panel connection component. The support frame slides on the photovoltaic panel connection component, so that the support frame can drive the cleaning roller brush and the electrostatic adsorption component to slide and clean on the solar photovoltaic panel, thereby comprehensively cleaning the solar photovoltaic panel.

[0036] like Figure 1-3 A solar photovoltaic panel surface cleaning device is shown. Figure 1 A solar photovoltaic panel surface cleaning device includes a support frame 1, a cleaning roller brush 2, an electrostatic adsorption component 3 and a photovoltaic panel connection component 4.

[0037] The cleaning roller brush 2 is rotatably connected to the support frame 1 , and soft brushes are evenly arranged on the circumference of the cleaning roller brush 2 .

[0038] Reference Figure 1 and Figure 2 The electrostatic adsorption component 3 is connected to the side wall of the support frame 1 near the cleaning roller brush 2. The electrostatic adsorption component 3 generates static electricity to adsorb dust on the surface of the solar photovoltaic panel.

[0039] The electrostatic adsorption component 3 includes a dust collecting shell 33, an adsorption plate 31 and a friction roller 32. The dust collecting shell 33 is fixedly connected to the support frame 1. The friction roller 32, the adsorption plate 31 and the cleaning roller brush 2 are all installed inside the dust collecting shell 33. A dust collecting port 331 is opened on the dust collecting shell 33 along the length direction of the cleaning roller brush 2. The dust collecting port 331 is used to collect dust.

[0040] During the process of electrostatic adsorption of dust, the dust on the surface of the solar photovoltaic panel is brushed and lifted by the cleaning roller brush 2, enters the dust collecting shell 33 through the dust collecting port 331, and is adsorbed by the adsorption plate 31 through static electricity. The adsorption plate 31 is located in the dust collecting shell 33, which can enhance the adsorption and collection effect of dust. The dust collecting shell 33 provides further protection for the dust collection on the adsorption plate 31. When the dust on the adsorption plate 31 falls, it will fall directly into the dust collecting shell 33, reducing the situation where the dust falls back on the solar photovoltaic panel, thereby improving the cleaning effect to a certain extent, reducing the repeated cleaning process, and improving the cleaning efficiency.

[0041] The adsorption plate 31 is detachably connected to the inside of the dust collecting shell 33. A fixed slot 332 is provided on the side wall inside the dust collecting shell. The side of the adsorption plate 31 is located in the fixed slot 332. The cleaning roller brush 2 is rotatably connected to the inside of the dust collecting shell 33. The adsorption plate 31 is arranged parallel to the cleaning roller brush 2.

[0042] During the cleaning process of the solar photovoltaic panel, the dust on the support frame 1 is brushed by the cleaning roller brush 2. The dust will be raised during the brushing process. The adsorption plate 31 has static electricity, and the dust can be effectively adsorbed by the adsorption plate 31, thereby effectively cleaning the solar photovoltaic panel. The electrostatic dust suction can quickly adsorb dust and particles, speed up work efficiency, and reduce impact and friction damage to the surface of the solar photovoltaic panel.

[0043] A plurality of dust-retaining grooves 311 are evenly arranged on the side wall of the adsorption plate 31 close to the cleaning roller brush 2 .

[0044] The dust-attaching groove 311 effectively increases the surface roughness of the adsorption plate 31, thereby effectively increasing the surface area of ​​the adsorption plate 31, making the adsorption surface larger and more effectively adsorbing the dust on the solar photovoltaic panel. Increasing the surface roughness of the adsorption plate 31 can provide more adsorption points, making it easier for dust to be adsorbed and fixed on the adsorption plate 31, thereby improving the dust removal efficiency. At the same time, the rough surface can increase the friction between the adsorption plate 31 and the dust particles, making it easier to capture tiny particles, preventing dust particles from easily falling off under the action of wind or other external forces, and extending the service life of the adsorption plate 31.

[0045] The friction roller 32 is provided on the upper end surface of the suction plate 31 , and the peripheral surface of the friction roller 32 abuts against the end surface of the suction plate 31 . A plurality of friction rollers 32 are provided.

[0046] The friction roller 32 rotates and rubs against the adsorption plate 31, so that the adsorption plate 31 can generate static electricity, so that the adsorption plate 31 can effectively adsorb dust on the solar photovoltaic panel, thereby reducing the impact or damage to the solar photovoltaic panel during the cleaning process, saving cleaning costs, and no harmful by-products are produced during the electrostatic dust collection process, which is environmentally friendly.

[0047] A plurality of plastic strips 321 are evenly arranged on the circumference of the friction roller 32 .

[0048] The friction between the plastic strips 321 and the adsorption plate 31 can produce a stronger electrostatic effect, making the electron transfer more significant, accelerating the efficiency of static electricity generation, thereby enhancing the strength and stability of static electricity, more effectively removing dust and stains on the surface of the solar photovoltaic panel, and improving cleaning quality and efficiency.

[0049] Reference Figure 1 and Figure 3The photovoltaic panel connection component 4 is used to connect with the photovoltaic panel, and the support frame 1 is slidably connected to the photovoltaic panel connection component 4.

[0050] During the cleaning process of the solar photovoltaic panel, the support frame 1 is connected to the solar photovoltaic panel through the photovoltaic panel connecting component 4, and the support frame 1 slides on the photovoltaic panel connecting component 4, so that the support frame 1 can drive the cleaning roller brush 2 and the electrostatic adsorption component 3 to slide and clean on the solar photovoltaic panel, thereby comprehensively cleaning the solar photovoltaic panel.

[0051] The photovoltaic panel connection assembly 4 includes a fixing rod 41 and a fixing clamp 42. The fixing rod 41 is arranged perpendicular to the length direction of the cleaning roller brush 2. Two fixing rods 41 are symmetrically arranged along the midpoint of the cleaning roller brush 2. A fixing clamp 42 is arranged at the end of the fixing rod 41. The fixing clamp 42 is used to clamp the solar photovoltaic panel.

[0052] During the cleaning process, the edge of the solar photovoltaic panel is stably clamped by the fixing clamp 42, and two fixing rods 41 are symmetrically arranged to increase the stability during the cleaning process and reduce the shaking of the support frame 1 during the cleaning process, thereby reducing unnecessary friction between the solar photovoltaic panel and the cleaning roller brush 2, so that the cleaning roller brush 2 lightly wipes the surface of the solar photovoltaic panel, effectively cleaning the surface of the solar photovoltaic panel.

[0053] A sliding groove 411 is provided on the side wall of the fixed rod 41 near the cleaning roller brush 2 along the length direction of the fixed rod 41. The end of the support frame 1 near the fixed rod 41 is rotatably connected to the sliding wheel 11, which is located in the sliding groove 411 and can slide in the sliding groove 411. The sliding wheel 11 slides in the sliding groove 411, thereby allowing the support frame 1 to move on the solar photovoltaic panel. This structure is simple and compact, which increases the stability of the support frame 1 to a certain extent, thereby increasing the stability of cleaning and reducing the vibration of the electrostatic adsorption component 3. Furthermore, the adsorption of dust by the adsorption plate 31 is more stable, reducing the possibility of dust falling.

[0054] The fixing clamp 42 includes an upper clamping plate 421 and a lower clamping plate 422. The upper clamping plate 421 is slidably connected to the end of the fixing rod 41. A clamping groove 412 is provided on the side wall of the fixing rod 41 near the upper clamping plate 421. The side edge of the upper clamping plate 421 is located in the clamping groove 412. A limiting groove 413 is provided on the inner wall of the clamping groove 412. The upper clamping plate 421 is fixedly connected to the limiting block 423 near the side wall of the clamping groove 412. The limiting block 423 is located in the limiting groove 413. A rotating rod 424 is passed through the upper clamping plate 421. The rotating rod 424 is threadedly engaged with the upper clamping plate 421. The end of the rotating rod 424 is rotatably connected to the fixing rod 41. The lower clamping plate 422 is fixedly connected to the end of the fixing rod 41. The cross-section of the lower clamping plate 422 is L-shaped.

[0055] When the solar photovoltaic panel needs to be clamped, just place the corners of the solar photovoltaic panel on the lower clamping plate 422, and rotate the rotating rod 424 to make the upper clamping plate 421 slide toward the lower clamping plate 422 on the clamping groove 412, thereby effectively clamping the solar photovoltaic panel.

[0056] The cleaning roller brush 2 , the friction roller 32 , and the sliding wheel 11 in the embodiment of the present application can all be driven by a driving motor.

[0057] The implementation principle of a solar photovoltaic panel surface cleaning device in an embodiment of the present application is as follows: in the process of cleaning the surface of the solar photovoltaic panel, the edge of the solar photovoltaic panel is first clamped by a fixing clamp 42, and the cleaning roller brush 2 and the friction roller 32 are started after the clamping is stable. The cleaning roller brush 2 can brush the surface of the solar photovoltaic panel. Fine dust will be raised during the brushing process. The plastic strip 321 on the friction roller 32 and the adsorption plate 31 continuously rub against each other to generate static electricity, which can quickly adsorb the fine dust, thereby achieving quick and effective cleaning of the solar photovoltaic panel.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
