Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel cleaning equipment, and in particular to photovoltaic panel cleaning equipment and a cleaning method for photovoltaic power station construction. Background Art

[0002] With the rapid economic development and the increasing scale of production and construction, traditional energy is becoming less and less. The development and utilization of new energy has become an inevitable path for economic growth and sustainable development. Photovoltaic power station is a power generation system that utilizes solar energy and adopts special materials such as crystalline silicon panels, inverters and other electronic components. It is a photovoltaic power generation system that is connected to the power grid and transmits electricity to the power grid. Photovoltaic power station, photovoltaic panels in photovoltaic power stations are prone to dust and bird droppings on the surface after long-term use. It is necessary to use cleaning robot equipment to regularly clean the photovoltaic panels to increase the power generation of the photovoltaic panels.

[0003] The existing cleaning robot equipment walks on the surface of the photovoltaic panel through the crawler when cleaning the photovoltaic panel, and the rotating main cleaning roller brush cleans the dust and bird droppings on the surface of the photovoltaic panel. At the same time, the first nozzle on the square tube sprays water to the surface of the photovoltaic panel, and the dust and bird droppings on the surface of the photovoltaic panel are cleaned by the cooperation of water and the main cleaning roller brush. However, the width of the main cleaning roller brush is fixed, while the width of different photovoltaic panels is different. When cleaning photovoltaic panels with a wider width, only photovoltaic panels with the same distance as the length of the main cleaning roller brush can be cleaned at a time. The cleaning robot equipment needs to repeat back and forth many times to complete the cleaning of dust and bird droppings on the surface of photovoltaic panels with a wider width.

The photovoltaic panel cleaning device for photovoltaic power station construction according to claim 1 is characterized by: The end of the T-shaped column (113) is fixedly connected to one end of the main cleaning roller brush (105); a driving motor (111) is fixedly arranged on the back of the concave frame (106); a working end of the driving motor (111) is fixedly connected to the other end of the main cleaning roller brush (105); two groups of connecting frames (104) are fixedly arranged between the square tube (110) and the concave frame (106); two groups of extension plates (107) are fixedly arranged on the side of the concave frame (106); a left frame (108) is fixedly arranged on one side of the machine body (100); and the left frame (108) and the extension plate (107) are fixedly connected by bolts.

9. A method for cleaning photovoltaic panels for photovoltaic power station construction, using the cleaning device according to any one of claims 1 to 8, characterized in that: The specific steps include: S1, placing the cleaning robot device on the surface of the photovoltaic panel to be cleaned, connecting the delivery pipe (102) to the external water supply pipe, and the first spray head (112) located below the square pipe (110) spraying water onto the surface of the photovoltaic panel; S2. The position of the auxiliary cleaning roller brush (205) is adjusted according to the width of the photovoltaic panel. During the adjustment, the installation motor (207) is turned on to drive the bidirectional screw rod (202) to rotate, thereby driving the nut seat (203) to move outward to a suitable position, thereby causing the horizontal plate (206) and the auxiliary cleaning roller brush (205) to move outward to a suitable position, and at the same time driving the round tube (400) to move along with it; S3, opening the valve (404), and the second nozzle (403) at the bottom of the circular tube (400) sprays water onto the surface of the photovoltaic panel below; S4, starting the driving motor (111) to drive the main cleaning roller brush (105) to rotate to clean the surface of the photovoltaic panel, starting the machine body (100), and rotating the crawler belt (101) to drive the machine body (100) to move on the surface of the photovoltaic panel, thereby driving the auxiliary cleaning roller brush (205), the horizontal plate (206) and the first vertical plate (201) to move; S5, the first vertical plate (201) moves to drive the side plate (300) to move, thereby driving the universal wheel (301) to roll on the surface of the photovoltaic panel; S6, the main cleaning roller brush (105) rotates to drive the T-shaped column (113) to rotate, thereby driving the installation drive belt (204), the external tooth column (213), the toothed drive belt (214), the T-shaped external tooth roller (216) and the auxiliary cleaning roller brush (205) to rotate accordingly, and the surface of the photovoltaic panel is cleaned by the arrangement of the main cleaning roller brush (105), the auxiliary cleaning roller brush (205), the first nozzle (112) and the second nozzle (403).
