Electrostatic dustproof photovoltaic panel rotary table

Abstract

The embodiment of the invention relates to a photovoltaic panel rotary table with an electrostatic dust prevention function. According to the electrostatic dust prevention device, a shell structure with good light transmittance is designed to be installed on the photovoltaic panel, an electrostatic field is additionally arranged on the surface of the device through an external power source, an electrostatic barrier is formed, dust is prevented from getting close to the photovoltaic panel, and therefore the dust prevention and non-contact cleaning functions are achieved. The motor for adjusting the azimuth angle can control the rotary table to rotate around the axis direction perpendicular to the ground. The elevation angle adjusting device is driven by four motors and can adjust the height and the pitch angle of the photovoltaic panel; the lifting function is completed by two motors and a lead screw structure, and the reliability is enhanced while the completion of the function is ensured; the electrostatic dustproof solar panel rotary table is good in universality, simple in structure, accurate in angle adjustment, high in reliability and stability, easy to manufacture and capable of being produced in batches.

Problems solved by technology

A very important factor that leads to the low efficiency of solar energy reception is the dust on the surface of the solar panel.

Often, areas with more sunlight have less shading from high-rise buildings and greater wind and sand. The surface of photovoltaic panels exposed to the atmosphere for a long time will be covered by dust and cannot receive sunlight well, thus affecting the power generation efficiency of photovoltaic panels.

In addition, when the dust on the photovoltaic board that has not been cleaned for a long time is unevenly distributed, the hot spot effect will appear and damage the circuit board

At present, the common treatment methods for the dust attached to the photovoltaic panel include manual cleaning, washing car cleaning, robot cleaning, etc., cleaning at least once every half a month, but the above cleaning methods all have the same shortcoming: reduce the light transmittance of the surface of the solar panel

Repeated friction between the brush and the surface of the photovoltaic panel for a long time will reduce the transmittance of the tempered glass, thereby increasing the reflectivity, and finally the photovoltaic panel can no longer be used

At the same time, most of the load-carrying devices currently used on the market cannot adjust the angle between the photovoltaic panel and the incident sunlight, and cannot achieve the highest solar energy utilization rate.
