Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic panel cleaning, and more specifically, it relates to a dry cleaning brush for photovoltaic panels. Background Art

[0002] Outdoor photovoltaic panels are usually laid in large areas to better absorb light energy. To enable photovoltaic panels to work better and more efficiently, it is often necessary to clean the dust and other substances covering their surfaces. A cleaning robot is used to identify and control its movement to adsorb the dust on the surface of the photovoltaic panel. Generally, dry cleaning is used for minor cleaning, and when major cleaning is required, it is combined with cleaning water for treatment.

[0003] When the photovoltaic panel cleaning robot is set to the dry cleaning state to clean the surface dust, if there is a large amount of water mist on the surface of the photovoltaic panel, when the robot cleans the surface, the dust and water mist will form lumps and adhere to the brush, resulting in poor cleaning effect and secondary pollution. Summary of the Utility Model

[0004] Therefore, to solve the above deficiencies, the utility model provides a dry cleaning brush for photovoltaic panels here.

[0005] The purpose and effect of a dry cleaning brush for photovoltaic panels of the utility model are achieved by the following specific technical means:

[0006] Its structure includes moving wheels, a control box, a dust removal grid, a brush, a baffle, and a rear scraper. Two moving wheels are installed on the left and right sides of the control box. The control box is connected to and controls the dust removal grid. The brush is installed directly below the dust removal grid. The baffle is an integral structure with the dust removal grid. The rear scraper is connected to the lower part of the dust removal grid.

[0007] The brush includes a main roller body, scraping rods, and sleeves. The sleeves are fixed on the left and right sides of the main roller body and nested with the baffle. The scraping rods include outer scraping bodies, movable scraping bodies, and sliding rods. The sliding rods penetrate the outer scraping bodies and are placed inside the main roller body. The sliding rods are connected to and move together with the movable scraping bodies. When the whole rotates, the sliding rods move along the slideway due to their own gravity. When the sliding rods push the movable scraping bodies outwards, the movable scraping bodies will be elastically expanded to the left and right by their own internal elasticity, so as to fit the surface of the photovoltaic panel. The movable scraping bodies are located inside the outer scraping bodies to limit the position and elasticity. There are nine outer scraping bodies.

[0008] Preferably, the scraping rods are evenly distributed on the outer surface of the main roller body. The scraping rods are evenly distributed in a circular shape. The outer scraping bodies are fixed on the outer surface of the main roller body. When the brush rotates for cleaning, the dust scraped is adsorbed and collected by the dust removal grid at the upper end. The rear scraper is placed at the rear end of the movement of the baffle to further scrape and intercept the dust.

[0009] Preferably, the sliding rod includes an elastic support block, a connecting body, an extension rod, a gravity body, and a limiting channel. The extension rod is supported between the connecting body and the gravity body. The gravity body drives the extension rod to move along the limiting channel. When the elastic support block gradually moves outwards as the movable scraping body moves outwards, and when it stretches by its own elastic force, it will be squeezed by the elastic support block.

[0010] Preferably, the elastic support block is installed between the scraping body and the movable scraping body. The connecting body and the movable scraping body are integrated. The gravity body has a certain gravity and can drive the connecting part to move together.

[0011] Preferably, the movable scraping body includes a compression elastic body, a soft scraping body, and a push head. The soft scraping body wraps and fits on the outer surface of the compression elastic body. The soft scraping body and the push head are of an integrated structure. The compression elastic body is in a squeezed state inside the scraping body. The push head has a certain slope to better scrape the ash layer.

[0012] Preferably, the rear scraping plate includes a relatively soft body, an elastic body, and an arc-shaped head. The arc-shaped head and the relatively soft body are of an integrated structure. The relatively soft body is connected to the elastic body. The relatively soft body and the elastic body can be bent according to the force they bear. The arc-shaped head can further intercept dust and control the dust to be within the suction range of the dust removal grid.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] First, when the scraping rod rotates to the horizontal direction and reaches the lowest position, the sliding rod drives the movable scraping body to extend outwards by the gravity of the gravity body itself. The soft scraping body is stretched by the originally restricted elasticity of the compression elastic body to scrape against the dust on the surface of the photovoltaic panel. When the dust is loosened and pushed, the dust removal grid at the upper end of the roller brush will adsorb the dust. When the humid dust adheres to the surface of the soft scraping body, when the scraping rod rotates from the lowest end to the highest end, the gravity body drives the connecting part to move outwards along the limiting channel by its own gravity. The compression elastic body will be stressed and drive the soft scraping body to move into the inner part of the outer scraping body along the scraping of the elastic support block, so that the adhered dust can be loosened and assisted by the dust removal grid for adsorption. When there is water mist on the photovoltaic panel and the surface dust is treated together, the water mist and the dust form lumps and adhere to the surface of the roller brush, and the dust adhered to the surface of the roller brush can be treated together during the rolling cleaning process.

[0015] Second, a rear scraper is provided at the rear end of the movement of the rotary brush. When there is residual dust, it will be intercepted by the rear scraper, enabling the arc-shaped head to continuously contact the surface of the photovoltaic panel. The arc of the arc-shaped head itself can better scrape and intercept the dust, assisting the dust to be within the adsorption range of the dust removal grid as much as possible. After the dust is first scraped and processed at the front end, it will be moved together to further scrape and process the dust, so that the excess dust can be kept within the adsorption range of the dust removal grid as much as possible.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Embodiment 1:

[0025] As shown in Figure 1 to Figure 5 shown:

[0026] The utility model provides a photovoltaic panel dry cleaning roller brush, which structure includes a moving wheel 1, a control box 2, a dust removal grid 3, a roller brush 4, a baffle 5, and a rear scraper 6. The moving wheel 1 is provided with two mounted on the left and right sides of the control box 2, the control box 2 is connected and controlled with the dust removal grid 3, the roller brush 4 is mounted directly below the dust removal grid 3, the baffle 5 and the dust removal grid 3 are an integrated structure, and the rear scraper 6 is connected to the bottom of the dust removal grid 3;

[0027] The roller brush 4 includes a main roller body 41, a scraper rod 42, and a sleeve 43. The sleeve 43 is fixed to the left and right sides of the main roller body 41 and nested with the baffle 5; the scraper rod 42 includes an outer scraper body 11, a movable scraper body 22, and a slide rod 33. The slide rod 33 passes through the outer scraper body 11 and is placed inside the main roller body 41. The slide rod 33 is connected to the movable scraper body 22 and moves together with the slide rod 33 when the whole body rotates. The movable scraper body 22 is moved along the slideway by its own gravity when the slide rod 33 pushes the movable scraper body 22 outward, and the movable scraper body 22 will be stretched to the left and right sides by its own internal elasticity, so as to fit the surface of the photovoltaic panel. The movable scraper body 22 is located inside the outer scraper body 11 to limit its position and elasticity. The outer scraper body 11 is provided with nine. When the slide rod 33 rotates to the uppermost end along the whole body, the movable scraper body 22 will be driven into the inner part of the outer scraper body 11 by its own gravity, so that it returns to its original position.

[0028] Among them, the scraper rod 42 is evenly distributed on the outer ring surface of the main roller 41, and the scraper rod 42 is evenly distributed in a circular shape. The outer scraper 11 is fixed to the outer ring surface of the main roller 41. The roller brush 4 absorbs and collects the scraped dust through the dust removal grid 3 at the upper end when rotating for cleaning. The rear scraper 6 is placed at the rear end of the movement of the baffle 5 to further scrape and intercept the dust. The outer layer of the movable scraper 22 is made of rubber material, which can better fit the surface of the photovoltaic panel for scraping.

[0029] Among them, the sliding rod 33 includes an elastic support block a1, a connecting body a2, an extension rod a3, a gravity body a4, and a limiting path a5. The extension rod a3 is supported between the connecting body a2 and the gravity body a4. The gravity body a4 drives the extension rod a3 to move along the limiting path a5. When the movable scraper body 22 gradually moves outward and stretches out through its own elastic force, the elastic support block a1 will be squeezed. When the movable scraper body 22 changes its angle, the elastic support block a1 continues to contact the surface and is in a fitting state.

[0030] Among them, the elastic support block a1 is installed between the scraper body 11 and the movable scraper body 22, the connecting body a2 and the movable scraper body 22 are integrated, the gravity body a4 itself has a certain gravity that can drive the connecting part to move together, and the limiting path a5, through its own shape, assists the connecting moving part to limit the moving direction and position.

[0031] Among them, the movable scraping body 22 includes a compression elastic body 01, a soft scraping body 02, and a push head 03. The soft scraping body 02 wraps and adheres to the outer surface of the compression elastic body 01. The soft scraping body 02 and the push head 03 are of an integrated structure. The compression elastic body 01 is located inside the scraping body 11 and is in a squeezed state. The push head 03 has a certain slope to better scrape the ash layer. When the soft scraping body 02 and the compression elastic body 01 contact the photovoltaic panel, they will bend and change according to the required situation to fit.

[0032] Specific usage method and function of this embodiment:

[0033] In the present utility model, the dust removal grid 3 is controlled by the control box 2 to adsorb the dust at the lower end, and the movement is controlled by the moving wheels 1. The rolling brush 4 will rotate to make the scraping rod 42 rotate along the sleeve 43. When the scraping rod 42 rotates to the horizontal direction and reaches the lowest position, the sliding rod 33 drives the movable scraping body 22 to extend outwards by the gravity of the gravity body a4 itself. The gravity body a4 moves and is limited along the limiting channel a5. When the movable scraping body 22 gradually moves out of the outer scraping body 11, it will squeeze the elastic support block a1. The originally restricted elasticity of the compression elastic body 01 drives the soft scraping body 02 to stretch and scrape the dust on the surface of the photovoltaic panel. The inclined angle of the push head 03 itself can assist the dust to be better shoveled up. When the dust is loosened and pushed, the dust removal grid 3 at the upper end of the rolling brush 4 will adsorb the dust. When the dusty and humid dust adheres to the surface of the soft scraping body 02, when the scraping rod 42 rotates from the lowest end to the uppermost end, the gravity body a4 drives the connection part to move outwards along the limiting channel a5 by its own gravity. The compression elastic body 01 will be stressed to drive the soft scraping body 02 to move into the outer scraping body 11 along the scraping of the elastic support block a1. The elastic support block a1 scrapes the surface of the soft scraping body 02 during the movement through its own elastic stretching support force, so that the adhered dust can be loosened to assist the dust removal grid 3 for adsorption.

[0034] Embodiment 2:

[0035] As shown in the appendix Figure 6 shown:

[0036] Among them, the rear scraping plate 6 includes a relatively soft body m1, an elastic body m2, and an arc head m3. The arc head m3 and the relatively soft body m1 are of an integrated structure. The relatively soft body m1 is connected to the elastic body m2. The relatively soft body m1 and the elastic body m2 can bend and change according to the force they bear. The arc head m3 can further intercept the dust and control the dust to be within the suction range of the dust removal grid 3. The arc of the arc head m3 itself can better scrape and intercept the dust.

[0037] Specific usage method and function of this embodiment:

[0038] In the utility model, when the dust removal grid 3 absorbs the dust on the photovoltaic panel, the roller brush 4 is used to clean and scrape to assist in the absorption. A rear scraper 6 is provided at the rear end of the roller brush 4. When there is residual dust, it will be intercepted by the rear scraper 6. The elastic body m2 and the softer body m1 are bent and resisted by the force during the movement, so that the arc head m3 can continue to resist the surface of the photovoltaic panel. The curvature of the arc head m3 itself can better scrape and intercept the dust, and the auxiliary dust can be as much as possible in the range of the dust removal grid 3. After the roller brush 4 has finished processing, the dust can be further scraped and processed by the rear scraper 6.
