Description

Technical Field

[0001] The invention relates to the field of photovoltaic equipment, in particular to a self-cleaning photovoltaic energy collector. Background Art

[0002] Photovoltaic data collector is a device that collects data from photovoltaic grid-connected inverters, combiner boxes, weather stations, electric meters and other equipment in photovoltaic power stations through RS485, RS232 and RS422, and transmits it to the database through GPRS, Ethernet, WIFI, 3G and other methods.

[0003] Photovoltaic data collectors are generally powered by independent photovoltaic panels. Photovoltaic panels are exposed to the air for a long time and are easily covered with dust and other debris. Generally, the collectors are located at the edge of the photovoltaic area, surrounded by more vegetation and trees. Birds and other inhabitants are likely to leave bird droppings and other debris that are difficult to clean on the photovoltaic panels. After drying, the droppings will remain on the photovoltaic panels very stubbornly, making them difficult to clean, and even have a certain corrosive effect on the photovoltaic panels. Traditional cleaning equipment mostly uses roller components for cleaning, and the contact cleaning dirt surface is limited. In addition, stubborn dirt remaining on the cleaning components is likely to cause smear pollution in other places where they pass by, reducing the power generation effect of the photovoltaic panels and causing the collector to be unable to send and receive signals. Therefore, a self-cleaning photovoltaic energy collector is proposed. Summary of the invention

[0015] (1) The self-cleaning photovoltaic energy collector described in the present invention has a switching lever used to adjust the position of the third gear and the fourth gear. When the fourth gear and the first gear are meshed together, the first screw rod rotates to drive the moving block to move, thereby adjusting the distance between the first connecting sleeve and the second connecting sleeve, adjusting the angle between the mounting frame and the connecting plate, and adjusting the inclination of the mounting frame, so that the cleaning belt is more closely attached to the side wall of the first photovoltaic panel, increasing the adhesion between the cleaning belt and the first photovoltaic panel, increasing the cleaning intensity, and facilitating appropriate corresponding adjustments according to the ease of dirt removal.
