Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to a self-cleaning and dust-preventing device for photovoltaic panel surfaces. Background Technology

[0002] Photovoltaic panels (solar panels) are devices that convert solar energy into electrical energy using the photovoltaic effect of semiconductor materials. They are typically composed of multiple photovoltaic modules connected in series or parallel, and their surface is covered with tempered glass with high light transmittance to protect the internal solar cells. Their power generation efficiency is directly affected by the intensity and angle of sunlight, as well as the cleanliness of the surface. If exposed to the outdoors for a long time, pollutants such as dust, bird droppings, and pollen will adhere to the glass surface, forming a shading layer that causes light scattering or absorption, significantly reducing the photoelectric conversion efficiency. Regular cleaning is a key measure to maintain the efficient operation of photovoltaic panels.

[0003] A search revealed that Chinese Patent Publication No. CN220122854U discloses a photovoltaic panel cleaning device. This device has the characteristic of good cleaning effect. However, the cleaning wheel of the cleaning component of this device rotates through the dust suction port to clean, and relies solely on the vacuum cleaner to suck up dust through the dust collection pipe. If the amount of sand and dust is too large or contains debris, it is easy to accumulate on the edge of the dust suction port or in the gap between the cleaning wheel and the housing. After gradually hardening, it will hinder the rotation of the cleaning wheel and affect the cleaning effect. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a self-cleaning and dust-prevention device for photovoltaic panel surfaces. It achieves the effect of first crushing and then automatically cleaning debris on the photovoltaic panel surface, and finally collects the cut and rolled debris through a dust collection structure. It has the advantages of good cleaning and dust removal effect, and the crushed debris avoids the cleaning device from getting stuck. This solves the above-mentioned technical problems.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning and dust-proof device for photovoltaic panels, comprising two sets of opposing mounting frames and a cleaning structure installed between the two sets of opposing mounting frames. One set of mounting frames has a first motor connected to one end, and a threaded rod rotatably mounted inside. The output end of the first motor is connected to the threaded rod. The other set of mounting frames has a guide rod welded inside. The cleaning structure includes two sets of movable plates connected to the two sets of mounting frames. A cleaning cover is connected to the inner side of the two sets of movable plates. A cleaning cover is mounted on one side of the cleaning cover. Equipped with a spraying device and a second motor at one end, the cleaning hood has a machine cover installed on its inner side wall. The output end of the second motor passes through the end side wall of the cleaning hood and the machine cover in sequence and is connected to a drive wheel. A drive belt is installed on the outer circumference of the drive wheel, and a material roll roller is connected to its end. A transmission wheel is connected to the inside of the other side of the drive belt. A material pick-up roller is connected to the end of the transmission wheel, and its other end passes through the machine cover and is rotatably installed inside the cleaning hood. A dust collection structure is connected to the top of the cleaning hood, and a scraper is connected to the bottom of the other side. A slot is opened at the bottom of the cleaning hood.

[0006] As a preferred embodiment of this utility model, one set of the movable plates is threadedly connected to the outer wall of the threaded rod, and the other set of the movable plates is slidably connected to the outer wall of the guide rod.

[0007] As a preferred technical solution of this utility model, the spraying device includes a water-blocking baffle installed inside the cleaning hood and a conveying pipe that passes through the end wall and side wall of the cleaning hood in sequence.

[0011] Compared with the prior art, this utility model provides a self-cleaning and dust-proof device for photovoltaic panel surfaces, which has the following beneficial effects: This invention uses a spraying device to spray water onto the surface of a photovoltaic panel. The output of a second motor drives a drive wheel to rotate a roll-up roller. Multiple sets of rolling teeth in a ring array on the outer circumference of the roll-up roller roll up debris that has been impacted by the spraying device on the photovoltaic panel, allowing the debris to enter the cleaning hood. The rotating wheel drives a take-up roller to rotate synchronously. Because the tips of the take-up teeth and the roll-up teeth are arc-shaped and sharp blade-shaped, the take-up teeth and the roll-up teeth are installed in a staggered manner.

[0017] Please see Figure 1-6 A self-cleaning and dust-prevention device for photovoltaic panels includes two sets of opposing mounting frames 1 and a cleaning structure 2 installed between the two sets of opposing mounting frames 1. One set of mounting frames 1 is connected to a first motor 11 at one end, and a threaded rod 12 is rotatably mounted inside. The output end of the first motor 11 is connected to the threaded rod 12. The other set of mounting frames 1 has a guide rod 13 welded inside. The cleaning structure 2 includes two sets of movable plates 21 connected to the two sets of mounting frames 1. A cleaning cover 22 is connected to the inner side of the two sets of movable plates 21. A spray device 23 is installed on one side of the cleaning cover 22, and a first... The second motor 24 is connected to a machine cover 3 installed on the inner side wall of the cleaning cover 22. The output end of the second motor 24 passes through the end side wall of the cleaning cover 22 and the machine cover 3 and is connected to a drive wheel 25. The outer circumference of the drive wheel 25 is connected to a drive belt 26, and the end is connected to a material roll roller 27. The other side of the drive belt 26 is internally connected to a drive wheel 28. The end of the drive wheel 28 is connected to a material pick-up roller 29, and the other end passes through the machine cover 3 and is rotatably installed inside the cleaning cover 22. The top of the cleaning cover 22 is connected to a dust collection structure 4, and the bottom of the other side is connected to a scraper 5. The bottom of the cleaning cover 22 has a slot 6.

[0018] Furthermore, the two sets of mounting brackets 1 are first snapped into the edges on both sides of the photovoltaic panel, and then fixed by bolts with a flexible structure wrapped around the top. During cleaning, the first motor 11 is started. The first motor 11 is a Y2 series three-phase asynchronous motor-Y2-90S-2. The rotation of the first motor 11 drives the threaded rod 12 connected to it to rotate. The corresponding movable plate 21 connected to the threaded rod 12 drives the cleaning cover 22 to move synchronously. At this time, another set of movable plates 21 slide synchronously on the outer wall of the guide rod 13, maintaining the stability of the movement of the cleaning cover 22.

[0019] Furthermore, as the cleaning hood 22 moves, the control valve 102 is opened, allowing the inside of the delivery pipe 101 to flow smoothly and drive water to spray out through the multiple nozzles of the spray pipe 103, thereby cleaning the surface of the photovoltaic panel and softening the stains on the surface of the photovoltaic panel. At the same time, the spray pipe 103 generates a certain impact force when spraying water on the surface of the photovoltaic panel, causing the debris on the surface of the photovoltaic panel to be lifted up, making it easier to clean.

[0020] Furthermore, as the cleaning hood 22 moves and the spray device 23 sprays water, the second motor 24 is activated. The second motor 24 is an RV08AL-D150-6P micro geared motor. The output of the second motor 24 drives the drive wheel 25 to rotate the winding roller 27. The multiple sets of winding teeth in the annular array on the outer circumference of the winding roller 27 roll up the debris on the photovoltaic panel that has been impacted by the spray device 23, causing the debris to enter the cleaning hood 22. At the same time, the drive wheel 25 rotates, driving the rotating wheel through the drive belt 26. The rotating wheel drives the material-taking roller 29 to rotate synchronously. Since the top of the material-taking tooth and the winding tooth are arc-shaped and the top is sharp blade-shaped, the material-taking tooth and the winding tooth are installed in a staggered manner. The material-taking tooth cuts and rolls up the debris rolled on the winding tooth. Through the cooperation of the winding roller 27 and the material-taking roller 29, the effect of automatically cleaning the debris on the surface of the photovoltaic panel is achieved, avoiding the cleaning device from getting stuck. At the same time, when the drive wheel 25, drive belt 26 and rotating wheel are working, they are covered by the machine cover 3 to prevent debris from entering and causing jamming.

[0021] Furthermore, when the picking teeth cut and roll up the debris rolled up on the rolling teeth, the vacuum cleaner 42 is activated. The vacuum cleaner 42 is a Genno JN-C1 industrial-grade wet and dry vacuum cleaner. The vacuum cleaner 42 applies pressure to the dust collection hood 41, so that the cut and rolled-up debris is collected through the dust collection hood 41 and then discharged through the vacuum cleaner 42 and the dust guide pipe 43. The end of the dust guide pipe 43 can be connected to the dust collection box for further processing of the collected debris.

[0022] In use, firstly, the two sets of mounting brackets 1 are internally snapped into the edges on both sides of the photovoltaic panel, and then fixed by bolts with a flexible structure wrapped at the top. Open the control valve 102 to allow the water to flow through the conveying pipe 101 and spray out through multiple nozzles of the spray pipe 103, softening the dirt on the surface of the photovoltaic panel and impacting the debris on the surface of the photovoltaic panel. Start the second motor 24. The output end of the second motor 24 drives the drive wheel 25 to drive the winding roller 27 to rotate. Multiple winding teeth in a ring array on the outer circumference of the winding roller 27 roll up the debris on the photovoltaic panel. The rotating wheel drives the picking roller 29 to rotate synchronously. The picking teeth cut and roll up the debris rolled up on the winding teeth. Through the cooperation of the winding roller 27 and the picking roller 29, the effect of automatically cleaning the debris on the surface of the photovoltaic panel is achieved. Finally, the dust collection structure 4 collects the cut and rolled-up debris, and the dust is discharged and collected through the vacuum cleaner 42 and the dust guide pipe 43. The scraper 5 scrapes off the water stains on the surface of the photovoltaic panel.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
