Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a double-nozzle automatic spraying machine for coatings on photovoltaic panels of a centralized photovoltaic power station. Background Art

[0002] Photovoltaic panels are devices that can convert solar energy into electrical energy, also known as solar panels. They are usually composed of multiple photovoltaic cells, which generate electric current by absorbing energy from sunlight. Photovoltaic panels are widely used in solar power generation systems. Photovoltaic panels can be used in independent solar power generation systems to provide power support for remote areas, mountain ranches, camping cars, etc., to achieve independent power supply. In addition, photovoltaic panels can also be used in some small applications, such as solar chargers and outdoor solar lights. Because the coating has super hydrophilic and anti-reflective properties, the coating on the surface of photovoltaic panels can help the photovoltaic panels to self-clean, reduce reflections and improve the photoelectric conversion efficiency, thereby increasing the energy output of photovoltaic panels, and can protect the surface of photovoltaic panels from external pollution, oxidation, corrosion and wear, reduce the influence of factors such as hot spot effect, and extend the service life of photovoltaic panels.

[0003] In the existing photovoltaic coating spraying machines, the traditional photovoltaic self-cleaning coating operation method uses wiping (a tool similar to a flat mop) and spraying (a long-pole spray gun). Due to the influence of the flat mop, the coating thickness is difficult to control; the long-pole spray gun swings up and down for spraying, which requires high experience of the operator and is labor-intensive due to the influence of the lever force; the wiping surface is not wide enough, and a photovoltaic panel needs to be wiped multiple times, which is inefficient. Therefore, it is urgent to design a dual-nozzle automatic sprayer for photovoltaic panel coatings in centralized photovoltaic power stations to solve the above problems. Utility Model Content

At the same time, the first synchronous belt 14 is in contact with the surface of the photovoltaic panel. When the first synchronous belt 14 moves on the surface of the photovoltaic panel, the left end of the automatic sprayer is moved on the surface of the photovoltaic panel.

[0049] The second belt motion structure 2 includes a second stepper motor 21, and the second stepper motor 21 is fixedly installed on the upper left side of the main frame 5; the second synchronous wheel 22 is rotatably installed inside the upper left side of the main frame 5, and the front end of the second synchronous wheel 22 is fixedly connected to the output end of the second stepper motor 21; the second synchronous belt 23 is arranged on the surface of the second synchronous wheel 22.

In the normal mode, the whole machine has the function of remote control operation. The automatic sprayer is placed on the photovoltaic panel in an inclined state. The first synchronous belt 14 and the third synchronous belt 34 are in contact with the surface of the photovoltaic panel, and the guide synchronous belt 38 is in contact with the top of the photovoltaic panel. The battery assembly 6 is remotely controlled through the electronic control assembly 7 to provide power to the automatic sprayer, and the second stepper motor 21 is controlled to rotate the second synchronous wheel 22 to drive the second synchronous belt 23 to move, and then the two spray assemblies 4 are controlled to move back and forth along the bracket to achieve spraying, and the spraying work of one unit of photovoltaic panel is completed. Then, the first synchronous wheel 12 and the third synchronous wheel 32 are controlled to rotate through the first stepper motor and the third stepper motor 31, and then the first synchronous belt 14 and the third synchronous belt 34 are driven to rotate, so that the automatic sprayer moves to the next photovoltaic panel for the next cycle of spraying, and automatic spraying is achieved.
