Solar power generation device that can automatically remove snow and dust

Abstract

Disclosed is a solar power generation device capable of automatically removing snow and dust. The solar power generation device capable of automatically removing snow and dust comprises a solar photovoltaic module, a base and a rotating unit mounted on the base. The rotating unit is provided with a motor and two vertical columns; a rotatable support shaft is arranged between the two vertical columns and fixedly provided with a sleeve perpendicular to the support shaft; a rotating shaft is arranged inside the sleeve and born by two bearings at the upper end and the lower end of the sleeve; the solar photovoltaic module is fixed at the upper end of the rotating shaft; a telescopic double-cross axle type universal coupler is connected between the lower end of the rotating shaft and the output shaft of the motor. The solar power generation device capable of automatically removing snow and dust can simulate the turning actions of living beings and eliminate snow and dust on a photovoltaic battery panel through centrifugal force generated by forward and reverse rotation of the photovoltaic battery panel, thereby obtaining high snow removing effects. Compared with vibration type dust removal, the solar power generation device capable of automatically removing snow and dust has small or even no influence on structural safety of the photovoltaic module, thereby avoiding damage to the photovoltaic module as much as possible. Compared with contact type dust removal, the solar power generation device capable of automatically removing snow and dust avoids the problem of abrasion on the surface of the photovoltaic battery panel.

Description

Technical field [0001] The invention relates to a solar power generation device. Background technique [0002] The regions with sufficient solar energy resources in my country are generally concentrated in the high-altitude areas in the west. These places have sufficient sunshine and less rainfall. The photovoltaic panels in solar power generation devices are more likely to accumulate dust. In addition, they are high-altitude areas, where there is sufficient snowfall in winter and the snow is difficult to dissolve, which will affect the battery The board receives sunlight and causes obstacles. When the dust and snow on the solar panels accumulate to a certain extent, it will have a significant impact on the power generation efficiency of the solar panels and cause damage to the solar panels. [0003] The utility model of Chinese Patent Application No. 200720036270.3 discloses a dust removal device for solar power generation panels. A windlass is installed on the upper part of the...

AI Technical Summary

Problems solved by technology

The invention patent application uses the spring and cam mechanism to control the vibrating inertial motion of the photovoltaic module to remove dust and snow. Because the vibration amplitude cannot be too large, it can only remove the thicker dust (snow) on the surface of the battery panel. For its thinner surface The dust (snow) layer, the dust (snow) removal effect is not ideal, and this tremor type dust (snow) removal method has a great impact on the structural safety of the photovoltaic module itself, and will cause damage to the photovoltaic module
