Description

Technical Field

[0002] Solar energy has been widely used as an ideal clean energy. Solar power generation is a way of utilizing solar energy by directly converting solar energy into electrical energy. Therefore, solar power generation is known as an ideal energy source. After the blizzard, ice and snow affect the power generation of photovoltaic power stations, and also cause devastating damage to the equipment and structure of photovoltaic power stations, directly leading to the rupture of photovoltaic modules and the collapse of brackets. Therefore, it is necessary to set up an automatic snow melting device to protect photovoltaic power generation modules.

[0003] Chinese utility model patent CN202321711012.6 provides a snow-melting device on the surface of an outdoor photovoltaic power generation component. The heat-generating belt of the device is arranged under the solar panel. The heat-generating belt is driven by a displacement component to move along the mounting frame to the top of the solar panel, and then the ice and snow are melted; at the same time, the inclination angle of the heat-generating belt can be changed, and the heat-generating belt can shovel the ice and snow on the solar panel, thereby saving electricity consumption.

[0004] However, the function of the heating belt to shovel snow from the photovoltaic panels after rotation can be used in basic snowy weather; because in very severe freezing and snowy weather, the snow on the photovoltaic panels will form layers, and the snow close to the photovoltaic panels will freeze to the surface of the photovoltaic panels. If the snow shoveling function is used forcefully, it may cause damage to the glass of the photovoltaic panels. Utility Model Content
