Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cleaning robots, in particular to a roller brush shock absorbing mechanism and a cleaning robot based thereon. Background Art

[0002] The photovoltaic cleaning robot is a device that cleans dust from the surface of photovoltaic panels. Its working principle is to detect the degree of contamination and location of photovoltaic panels through sensors, and then use machine learning algorithms to analyze and process the data to autonomously plan the best cleaning path and method. During the cleaning process, the robot will make dynamic adjustments based on the actual situation to ensure the cleaning effect. This cleaning method can save effort and quickly clean photovoltaic equipment to avoid residual dust and other debris.

[0003] Existing photovoltaic cleaning robots are prone to bumps during driving due to the natural environment where the photovoltaic panels are installed. The bumps can easily affect the cleaning components, causing them to shake. Since the cleaning components are mostly in contact with the surface of the photovoltaic panels during the cleaning process, the shaking of the cleaning components not only affects their own stability, but also easily collides with the photovoltaic panels, causing deviations in the cleaning work and affecting the quality of the cleaning work.

[0030] In the process of the roller brush shock absorbing mechanism performing cleaning operations on the photovoltaic panel as the photovoltaic cleaning robot travels, the photovoltaic cleaning robot is prone to bumps during travel. In this application document, an electric swing arm 5 is provided on the outside of the frame 1, and a channel is provided on the surface of the electric swing arm 5. A plurality of equally spaced shock absorbers 6 are provided on the inside of the channel, and the shock absorbers 6 are connected to the frame 1. If the roller brush shock absorbing mechanism is affected by the bumps during the travel of the photovoltaic cleaning robot and shakes, the connection between the shock absorber 6 and the frame 1 can effectively buffer the shaking force of the electric swing arm 5 during the bumps, effectively reduce the adverse effects of this force on the frame 1 and the cleaning roller brush 2, improve the stability of the cleaning roller brush 2, and further ensure the cleaning effect on the photovoltaic panel.

[0031] like Figure 3 , Figure 4 As shown, a positioning ring 11 is arranged on the surface of the electric swing arm 5, and a first connecting arm 12 is connected to the positioning ring 11 through a rotating shaft, and a second connecting arm 13 is connected to the bottom end of the first connecting arm 12 through a rotating shaft, and the second connecting arm 13 is installed on the outside of the electric swing arm 5. The combination of the positioning ring 11, the first connecting arm 12 and the second connecting arm 13 stably connects the electric swing arm 5 and the frame 1, and has a limiting effect on the frame 1.

[0033] like Figure 3 , Figure 4 As shown, a pressure sensor 4 is provided on the frame 1 through a connection plate, and the pressure sensor 4 is located below the driving shaft 3. When the pressure sensor 4 moves to a specified position along with the movement of the electric swing arm 5, the pressure sensor 4 fits with the surface of the photovoltaic panel and detects the pressure of the photovoltaic panel surface 4. At this time, the cleaning roller brush 2 fits with the surface of the photovoltaic panel.

The amount of water sprayed from the upper position of the photovoltaic panel surface is greater than the amount of water sprayed from the lower position. The water sprayed by the first cleaning spray group 9 can quickly and fully dissolve the impurities on the surface of the photovoltaic panel. The phenomenon of uneven cleaning uniformity caused by the rapid fall of water during the cleaning process is reduced, and the comprehensiveness of the cleaning work is improved.

The intelligent driving base 20 in this application is connected to the electric swing arm 5, the electric rocker arm 18 and the electric rotating base 19 through a line. When the pressure sensor 4 senses the pressure from the photovoltaic module, the pressure sensor 4 is connected to the intelligent driving base 20 signal, and the intelligent driving base 20 can determine whether the electric swing arm 4 and the cleaning roller brush 2 are in a suitable position.
