Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a new energy photovoltaic power generation device with automatic dust and snow removal and a use method thereof. Background Art

[0002] Photovoltaic power generation device is a system that uses solar panels to convert sunlight into electrical energy. The degree of light received by solar panels and photovoltaic panels is the main factor affecting their power generation efficiency. The impact of dust and snow on photovoltaic panel power generation is significant, and they can significantly reduce the power generation efficiency of photovoltaic panels. Dust and snow covering the surface of photovoltaic panels will block part of the sunlight, reduce the effective amount of light reaching the photovoltaic panels, and reduce the power generation efficiency. The dust layer will absorb part of the sunlight, causing the surface temperature of the photovoltaic panels to rise, accelerating the aging of the photovoltaic panels and shortening their service life. The weight of snow will cause mechanical pressure on the photovoltaic panels and their support systems, causing structural damage. Therefore, cleaning dust and snow from photovoltaic power generation devices is of great significance to ensure the power generation efficiency and service life of the power generation devices. Qingyang, Gansu is located in the loess plateau gully area in the middle and lower reaches of the Yellow River. The photovoltaic power generation devices here are affected by the loess plateau and are seriously polluted by dust. The traditional cleaning method for photovoltaic power generation devices is manual scrubbing, which is labor-intensive and inefficient.

[0003] The existing patent CN202110593010.0 discloses a snow and dust removal device for a solar photovoltaic power station and a method of using the same. The driving wheel group and the driven wheel group are stuck on both sides of the solar photovoltaic panel. A cleaning device is provided between the driving wheel group and the driven wheel group. At least one rubber strip is provided at the bottom of the cleaning device. Brush strips are also provided on both sides of the rubber strip. Multiple nozzles are also provided on both sides of the cleaning device. A water tank is provided on the top of the cleaning device. The water tank is connected to multiple nozzles through a water pump. A control center is provided on one side of the water tank. The control center is electrically connected to the driving wheel group and the water pump. An electric storage device is provided inside the control center. The electric storage device is electrically connected to the solar photovoltaic panel. The driving wheel group and the driven wheel group are stuck on both sides of the solar photovoltaic panel. The rubber strips and brush strips at the bottom of the cleaning device have the effect of cleaning dust and wiping water. The nozzle on the cleaning device can spray water. In combination with the rubber strips and brush strips, the driving wheel group and the driven wheel group are used to slide back and forth on the solar photovoltaic panel to repeatedly clean the dust or snow on the solar photovoltaic panel. The above patent only cleans the photovoltaic panels by spraying, rubber strips and brushes, and the cleaning effect is relatively poor; it is impossible to effectively clean the heavy snow.

After the slide seat slides to the bottom of the mounting seat, the first motor reverses, the slide seat resets, and the air nozzle blows dry the surface of the photovoltaic module.
