Single-axis tracking support with automatic cleaning and posture detecting functions

Abstract

The invention discloses a single-axis tracking support with automatic cleaning and posture detecting functions. A photovoltaic plate seat is rotatably mounted on a support seat, a circular arc frame is mounted on one side or at the bottom of the photovoltaic plate seat, and the circle center of the circular arc frame is colinear with the rotating center of the photovoltaic plate seat; a cleaning device is mounted on the photovoltaic plate seat to enable a strip-shaped hairbrush of the cleaning device to clean the surface of a photovoltaic plate, an illuminance sensor is mounted on the photovoltaic plate seat and used for detecting light intensity, and a glass plate flush with the surface of the photovoltaic plate is arranged at the top of the illuminance sensor; a driving device is mounted on a support seat, and the output end of the driving device is connected with the circular arc frame through a transmission mechanism to drive the photovoltaic plate seat to rotate and connected with the cleaning device through a transmission switching device to drive the strip-shaped hairbrush to move along the surface of the photovoltaic plate. The single-axis tracking support has the advantages that an original driving power source of the tracking support can be utilized to realize automatic cleaning, and self judgment of posture angle can be realized through a detection device so as to realize accurate posture adjusting.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a single-axis tracking bracket with functions of automatic cleaning and attitude detection. Background technique [0002] Solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. The energy of solar energy reaching the ground every second is as high as 800,000 kilowatt-hours. If 0.1% of the solar energy on the earth's surface is converted into electrical energy, the conversion rate is 5%, and the annual power generation can reach 5.6×1012 kilowatt-hours, which is equivalent to 40% of the world's energy consumption. times. It is precisely because of these unique advantages of solar energy that after the 1980s, the types of solar cells have continued to increase, the ...
