Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, specifically to an adsorption-type photovoltaic cleaning robot. Background Technology

[0002] The benefits of regularly cleaning photovoltaic (PV) panels are twofold: first, it maintains the output power of the PV power generation system, ensuring its long-term stable operation; second, it extends the lifespan of the PV panels, reducing maintenance and replacement costs. After cleaning and maintenance, not only will the output power of the PV power generation system be improved, but operating and maintenance costs will also be reduced. Existing technology has disclosed a series of relatively advanced automated PV cleaning equipment, such as tracked cleaning robots. However, for some PV panels with large angles, ordinary tracked cleaning robots cannot move normally and are prone to slipping, especially after water washing when the PV panel surface is relatively wet, making slipping even more likely and affecting operational safety and cleaning efficiency. Therefore, this project was developed to address these issues through in-depth research. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an adsorption-type photovoltaic cleaning robot, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adsorption-type photovoltaic cleaning robot, including a tracked robot, wherein electric cleaning rollers are respectively provided on the front and rear sides of the tracked robot, a semi-circular shell is fastened to the outside of the electric cleaning rollers, a negative pressure dust suction mechanism is provided on the shell, and two sets of negative pressure adsorption mechanisms are symmetrically arranged inside the tracked robot along its central axis. The negative pressure adsorption mechanism includes an exhaust chamber and an adsorption chamber. The exhaust chamber is an L-shaped pipe, and a negative pressure fan is installed inside the exhaust chamber. The adsorption chamber is located at the lower end of the exhaust chamber. The connection between the adsorption chamber and the L-shaped pipe is a rigid material cavity structure, and a soft silicone gasket is provided at the lower part of the rigid material cavity structure.

[0005] The aforementioned negative pressure dust collection mechanism includes a dust collection hood mounted on the housing, a dust discharge channel inside the dust collection hood, a dust filter screen at the outlet end of the dust discharge channel, a dust collection fan outside the dust filter screen, and a dust collection component at the bottom of the dust discharge channel.

[0006] The aforementioned dust collection component includes a dust collection chamber located below the dust discharge pipe, and a dust collection box is inserted into the dust collection chamber. The dust collection box has a rectangular trough structure and is located below the dust filter screen.

[0007] A circular iron plate is provided on the top of the upper shell of the tracked robot.

[0008] The aforementioned cleaning robot also includes a rotary-wing drone, the lower part of which is equipped with a suspension rope, and an electromagnet is installed at the lower end of the suspension rope. The electromagnet can be magnetically attracted to a circular iron plate. Beneficial effects

[0009] This utility model provides an adsorption-type photovoltaic cleaning robot. It offers the following advantages: Based on existing tracked robots, this adsorption-type photovoltaic cleaning robot features two sets of electric cleaning rollers and a negative pressure dust collection mechanism on both the front and rear sides of the tracked robot. Dust stirred up by the rollers is collected by the negative pressure dust collection mechanism, preventing secondary contamination of the photovoltaic panels. Simultaneously, two sets of negative pressure adsorption mechanisms are added to the tracked robot, using negative pressure to adhere the robot to the photovoltaic panel surface, counteracting downward lateral slippage and preventing slippage. When the cleaning robot passes through gaps in the photovoltaic panels, whether moving forward or backward, if one set of negative pressure adsorption mechanisms fails to perform its adsorption function due to the gap, the other negative pressure adsorption mechanism will continue to operate normally, ensuring the cleaning robot continues to function smoothly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Refer to the appendix of the instruction manual Figure 1-7 As can be seen, this application specifically designs an adsorption-type photovoltaic cleaning robot, including a tracked robot 1. The tracked robot 1 is characterized by having electric cleaning roller brushes 2 on its front and rear sides, with a semi-circular shell 3 fastened to the outside of each brush. A negative pressure suction mechanism is installed on the shell 3. Two sets of negative pressure adsorption mechanisms are symmetrically arranged along the central axis inside the tracked robot 1. The negative pressure adsorption mechanism includes an exhaust chamber 4 and an adsorption chamber 5. The exhaust chamber 4 is an L-shaped pipe, and a negative pressure fan 6 is installed inside it. The adsorption chamber 5 is located at the lower end of the exhaust chamber 4. The connection between the adsorption chamber 5 and the L-shaped pipe is a rigid material cavity structure, which will not deform due to negative pressure. A soft material cavity structure is provided at the lower part of the rigid material cavity structure. The silicone gasket is soft and fits perfectly against the photovoltaic panel, creating a sealed negative pressure space without scratching the panel surface. Dust kicked up by the electric roller brush is collected by the negative pressure suction mechanism, preventing secondary contamination of the photovoltaic panel. Simultaneously, two sets of negative pressure adsorption mechanisms are added to the tracked robot 1. These mechanisms use negative pressure to adhere the robot to the photovoltaic panel surface, counteracting downward lateral slippage and preventing slippage. When the cleaning robot passes through gaps in the photovoltaic panel, whether moving forward or backward, if one set of negative pressure adsorption mechanisms fails to adsorb due to the gap, the other set will continue operating normally, ensuring the cleaning robot continues its work smoothly.

[0021] In the specific implementation process, the above-mentioned negative pressure dust collection mechanism includes a dust collection hood 7 installed on the housing 3. A dust discharge channel 8 is opened inside the dust collection hood 7. A dust filter 9 is installed at the outlet end of the dust discharge channel 8. A dust collection fan 10 is installed outside the dust filter 9. A dust collection component is installed at the lower part of the dust discharge channel 8. The dust collection component includes a dust collection chamber 11 opened below the dust discharge channel. A dust collection box 12 is inserted into the dust collection chamber 11. The dust collection box 12 has a rectangular groove structure and is located below the dust filter 9. The dust collector 10 sucks the dust in the housing 3 into the dust collection chamber 11 through the dust discharge channel 8. After the dust is intercepted by the dust filter 9, it enters the lower dust collection box 12. After the cleaning operation is completed, the dust collection box 12 can be manually pulled out for cleaning.

[0022] It is worth noting that the cleaning robot can automatically calculate the suction force of the negative pressure adsorption mechanism corresponding to the downward force generated by the cleaning robot under different photovoltaic panel angles through the control system, and adjust it by adjusting the power of the wind pressure fan. This ensures that the suction force is neither too strong, which would make it difficult for the robot to walk, nor too weak, which would cause side slippage, thus making reasonable use of power resources. The tracked robot 1 can model and automatically plan its walking route on the photovoltaic panel, and can carry out normal cleaning operations without manual intervention.

[0023] Furthermore, in conjunction with the instruction manual appendix Figure 8 As can be seen, in the specific implementation process, a circular iron plate 13 is provided on the top of the cover of the tracked robot 1. The cleaning robot also includes a rotary-wing drone 14. A suspension rope 15 is provided on the lower part of the rotary-wing drone 14. An electromagnet 16 is installed at the lower end of the suspension rope 15. The electromagnet 16 can be magnetically attracted to the circular iron plate 13. After the current photovoltaic panel cleaning operation is completed, the rotary-wing drone 14 is controlled to fly to the position above the tracked robot 1, and the electromagnet 16 is placed down and magnetically attracted to the circular iron plate 13 on the tracked robot 1. The tracked robot 1 can be hoisted to the designated position and placed. At the same time as the tracked robot 1 is placed on the photovoltaic panel, the negative pressure adsorption mechanism is activated for adsorption. When the rotary-wing drone 14 takes the tracked robot 1 off the photovoltaic panel, the electromagnet 16 and the circular iron plate 13 are firmly attracted, and the negative pressure adsorption mechanism stops working, so that the tracked robot 1 is successfully hoisted.
