These are common knowledge to those skilled in the art, and selections or adaptive adjustments can be made based on existing technology and actual needs; therefore, they will not be described in detail here.

[0035] In some embodiments, the photovoltaic glass panel cleaning device uses an existing photovoltaic panel bracket as the mounting base and the frame of the photovoltaic panel bracket as a slide rail, or it can be configured separately.

[0036] In some embodiments, the traveling wheels 20 are symmetrically arranged on both sides of the bottom of the main frame 1, reciprocating along the edge of the photovoltaic panel support, driving the entire photovoltaic glass panel cleaning device to move above the photovoltaic glass panel, cleaning different parts of the photovoltaic glass panel, ensuring coverage of all areas. The traveling wheels 20 can move manually or automatically; when moving automatically, they are driven by an independently controlled motor.

[0037] In some embodiments, the upper drive shaft 5 and the lower drive shaft 8 are mounted in parallel on the main frame 1, with the upper drive shaft 5 on top, i.e., on the side away from the photovoltaic glass panel, and the lower drive shaft 8 on the bottom, i.e., on the side closer to the photovoltaic glass panel.

In this embodiment, there are 14 second bevel gears 6; the specific number and position should be adjusted adaptively according to actual needs.

[0039] In some embodiments, the upper transmission shaft 5 is one, and the lower transmission shaft 8 is two, each of which is provided with 14 quick-release interfaces 9 for installing disc brushes 10. The disc brushes 10 are hinged to the quick-release interfaces 9 through rotating shafts and can be replaced individually when damaged or severely worn, facilitating maintenance. The rotating shafts of the disc brushes 10 are provided with multiple limiting rings, and the height can be adjusted when installed on the quick-release interfaces 9 to adapt to the height of photovoltaic glass panels in different positions.

The number and position of the high-pressure air nozzles 14 are determined according to actual needs.

[0042] In some embodiments, the water pipes 11 are two and are arranged in parallel with the lower transmission shaft 8. The water pump 13 is installed on the main frame 1 and is connected to an external water source. The water pipes 11 are connected to the water outlet of the water pump 13. The water pipes 11 are provided with multiple umbrella-shaped nozzles 12 for spraying water to the disc brushes 10 below and / or the photovoltaic panel glass.

[0043] In some embodiments, the main frame 1 is also provided with a chemical liquid barrel 16 for containing cleaning chemical liquid.

[0045] The beneficial technical effects achieved by the utility model include:

[0046] Compared with the roller cleaning mode, the disc brush cleaning scheme has more stable advantages. First, the disc brush cleaning scheme can flexibly adjust the brush speed, and the spraying cleaning effect is better, which can more effectively remove stubborn stains and improve the cleaning effect of the photovoltaic glass plate. Second, the disc brush material is plastic or nylon, which will not damage the photovoltaic glass plate and is not easy to stain, protecting the surface of the photovoltaic glass plate from being scratched or damaged. In addition, the zigbee module group is matched to realize remote control, which can reduce labor cost, improve cleaning efficiency and prolong the service life of the photovoltaic panel.

[0047] In summary, the utility model has significant advantages in cleaning effect, photovoltaic panel protection and automatic control, which can improve the overall performance of the cleaning device and bring greater benefits to the photovoltaic glass plate industry.
