Automatic flight surface cleaning robot for photovoltaic array

Abstract

The invention discloses an automatic flight surface cleaning robot for a photovoltaic array, and relates to the technical field of photovoltaic module cleaning. A DC motor is connected with a power supply. The DC motor operates to drive an air pump to generate high pressure gas, and the gas is then transmitted to air nozzles through corresponding pipelines. The pipelines are installed on supports on the two sides of an unmanned aerial vehicle. The pipelines are provided with blow holes, and the air nozzles are installed at the blow holes. A scrubbing dust collection device is composed of a rotating motor, a lifting device, a universal coupling and cleaning brush heads. The lifting device is a telescopic cylinder, and the top end of a piston rod of the cylinder is connected with the rotating motor through the universal coupling. The rotating motor is connected with the cleaning brush heads. A high definition camera, an intelligent control unit, the DC motor and the rotating motor are all connected with the power supply. The intelligent control unit controls the high definition camera, the lifting device, the DC motor and the rotating motor. The automatic flight surface cleaning robot for the photovoltaic array can conduct surface cleaning on the photovoltaic array installed on roofs, water surfaces, farmland and slopes.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module cleaning, in particular to an automatic flying photovoltaic array surface cleaning robot. Background technique [0002] At present, photovoltaic power stations mostly use manual wiping and water gun cleaning. However, due to the difference in personnel level, the cleaning process is difficult to control, the cleaning effect is poor in consistency, and the cleaning efficiency is low. Among them, the water gun cleaning method consumes a lot of water, wears the component glass, affects the light transmittance and life, and is not suitable for water-shortage areas. [0003] There are also power stations that use mechanical cleaning. At present, most large heavy-duty vehicles are used as the chassis + roller brush method. When the vehicle is running, the roller brush moves together to wipe the dust on the surface of the components. The "Intelligent Photovoltaic Array Cleaning Vehicle" wit...

Problems solved by technology

However, its structure is fixed and is easily affected by the installation method of the photovoltaic array. Once the arrangement of the components in the array changes, the structure of the device will be readjusted, and the adaptability is poor.

[0006] From the above analysis, it can be seen that the main problems of mechanical cleaning devices are: ① need to be dragged by large heavy-duty vehicles, high power consumption, low degree of automation, and high requirements for array spacing and installation terrain; ② high cost of installing tracks; ③ Fixed structure, poor adaptability

These three defects limit the further popularization and application of external mechanical cleaning devices
