Photovoltaic sweeping equipment and control method thereof

Abstract

The invention provides photovoltaic sweeping equipment and a control method thereof. The photovoltaic sweeping equipment comprises a photovoltaic component and a photovoltaic sweeping device for sweeping the photovoltaic component, wherein the photovoltaic sweeping device comprises a framework, a rolling brush, moving wheels and an automatic control system; a moving wheel driving side component and a rolling brush driving side component are correspondingly arranged at two ends of the framework; the automatic control system comprises a control unit and two distance sensors; induction blocks arearranged at two ends of the photovoltaic component; and two distance sensors are correspondingly in wireless connection with the induction blocks to induce the induction blocks so as to send induction signals. According to the photovoltaic sweeping equipment and the control method thereof, targeted sweeping can be performed according to the amount of dust of the photovoltaic component, and an impact force on the photovoltaic component from the photovoltaic sweeping device can be effectively reduced in case of shutdown.

Description

technical field [0001] The invention relates to the technical field of cleaning devices, in particular to a photovoltaic cleaning device and a control method thereof. Background technique [0002] In the known technical field, since the solar cell panel is placed outdoors for a long time, dust accumulation is easily generated on the surface thereof. Accumulation of dust not only reduces the amount of light radiation received by photovoltaic modules, affects system efficiency, and reduces power generation, but also causes hot spot effects on photovoltaic panels, resulting in loss of power generation, affecting the life of modules, and causing safety hazards. At present, the photovoltaic cleaning robot uses a single-motor mechanism. When the robot with this structure is working, the speed of the walking wheel and the rotating brush are fixed values, which cannot be set according to the working conditions. This makes it take the same time to clean the surface of the photovolta...

Problems solved by technology

Dust accumulation not only reduces the amount of light radiation received by photovoltaic modules, affects system efficiency, and reduces power generation, but also causes hot spot effects on photovoltaic panels, resulting in loss of power generation, affecting the life of components, and causing safety hazards

At present, the photovoltaic cleaning robot uses a single-motor mechanism. When the robot with this structure is working, the speed of the walking wheel and the rotation speed of the rolling brush are fixed values, which cannot be set according to the working conditions.

This makes it take the same time to clean the surface of the photovoltaic panel with a lot of dust and less dust, and there is no specificity to the cleaning status of the dust; and the current photovoltaic cleaning device is usually equipped with sensors on both sides. When the sensor When the signal is sensed, the motor will stop rotating, but the robot will walk a certain distance due to inertia during the process from sensing the signal to stopping, which will cause the sensor of the robot to hit the sensing blocks at both ends of the photovoltaic module, causing certain damage to the photovoltaic module. shock
