Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning equipment, in particular to an automatic photovoltaic panel cleaning device. Background Art

[0002] The tilted installation of photovoltaic panels is a common installation method, especially suitable for places with a certain slope. By tilting the installation, photovoltaic panels can better absorb sunlight and improve power generation efficiency.

[0003] Cleaning photovoltaic panels is an important step in maintaining the performance and power generation efficiency of photovoltaic systems. During the cleaning process, dust, dirt and other obstructions on the surface of photovoltaic panels need to be removed to ensure that they can normally receive sunlight and convert it into electrical energy.

[0004] Most of the photovoltaic panel cleaning robots on the market use roller brushes. The cleaning robot is mounted on the photovoltaic panel, and the driving motor drives the walking wheels and the cleaning brushes to move. Auxiliary wheels are installed on both sides of the photovoltaic panel or on the track to resist the photovoltaic panel, and the cleaning brush is used to sweep the dust on the photovoltaic panel. However, bird droppings, corroded and bonded leaves, etc. remaining on the photovoltaic panel are attached to the photovoltaic panel. If they are cleaned with a single flexible brush, the cleaning effect is poor. Only the floating dust on the surface of the photovoltaic panel can be cleaned, and it is difficult to clean some impurities such as bird droppings. For this reason, we propose an automatic photovoltaic panel cleaning device to solve the above problems. Utility Model Content

[0025] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides an automatic cleaning device for photovoltaic panels, including a frame 1, a first cleaning component and a second cleaning component, wherein the first cleaning component includes a roller body 11 which is horizontally rotatably mounted inside the frame 1 and has bristles on its outer surface, and a first motor 12 which is mounted on one side of the frame 1 and is located at one end of the roller body 11 and is used to drive the roller body 11 to rotate; the second cleaning component includes a plurality of rotating brush body units 13 which are linearly arrayed on the frame 1, and the rotating brush body unit 13 includes a rod body 14 which is vertically rotatably mounted on the frame 1, a rotating body 15 which is located at the bottom of the rod body 14, a rubber strip 16 which is arranged on the outer surface of the rotating body 15, and a driving component which is used to drive the plurality of rotating brush body units 13 to rotate, and when cleaning is performed, the driving component drives the plurality of rod bodies 14 to rotate. The body 14 rotates, thereby driving the rubber strip 16 on the outer surface of the rotating body 15 to rotate. Under its own weight and in a rotating state, the rubber strip 16 can lift up the dust on the surface of the photovoltaic panel and the impurities attached to the panel surface. When the rubber strip 16 rotates, because multiple and linear arrays are installed, the surface area of ​​the photovoltaic panel can be covered. On the other hand, because the photovoltaic panel is in an inclined state, some impurities such as dried bird droppings and small gravel can slide down after being lifted up or be cleaned up by the subsequent roller body 11 with bristles. The first motor 12 is started to rotate the roller body 11 with bristles to clean the dust on the photovoltaic panel surface. The two cleaning settings can not only clean the dust on the photovoltaic panel, but also some impurities.

[0027] Preferably, the frame 1 is internally rotatably connected to two rotating shafts 2, on which travel wheels 21 are arranged, and the roller body 11 drives the travel wheels 21 on the rotating shaft 2 to move through a gear assembly, and the first motor 12 is started, the roller body 11 rotates, and the rotating shaft 2 is driven to rotate through the gear assembly, driving the travel wheels 21 on the rotating shaft 2 to move on the edge of the photovoltaic panel surface or on the track, thereby driving the entire device forward or backward.

[0028] Preferably, the driving assembly includes a second motor 3 for driving the rotating brush body unit 13 to rotate and a gear belt 31 for realizing power transmission of the rod bodies 14 of multiple rotating brush body units 13. When the second motor 3 is started, the output end of the second motor 3 drives the adjacent rotating brush body unit 13 rod bodies 14 to rotate through the gear belt 31, and then the rotating rotating brush body unit 13 rod body 14 drives the adjacent rotating brush body unit 13 rod body 14 to rotate through the gear belt 31, thereby realizing the rotational movement of multiple rotating brush body units 13.

[0029] Preferably, the gear assembly includes a first gear 4 connected to the rotating shaft 2 and a second gear 41 connected to the roller body 11. The first gear 4 is meshed with the second gear 41.

When the vacuum cleaner 51 is started, the dust raised after cleaning the rubber strip 16 and the brush roller body 11 is sucked into the dust box 5 to prevent the dust from falling into the cleaned area again and causing secondary dust falling.

[0031] Preferably, auxiliary wheels 6 are provided on both sides of the frame 1, and the auxiliary wheels 6 are in contact with the side edges of the photovoltaic panel frame. The wheel surfaces of the auxiliary wheels 6 are in contact with the two sides of the photovoltaic panel frame or the track, so that the auxiliary wheels 6 can move against the photovoltaic panel and can also limit the device to prevent it from slipping out of the photovoltaic panel.

[0032] Preferably, an openable rear cover 7 is connected to the rear side of the frame 1, and a handle frame 8 is connected to the top of the frame 1.

Opening the rear cover 7 makes it easy to check the internal situation of the device, and the setting of the handle frame 8 makes it easy to pick up the device.

[0033] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
