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

[0020] Please see Figure 1-3 A distributed photovoltaic power station cleaning robot includes a walking robot 1. The walking robot is equipped with omnidirectional wheels or tracked drive mechanism at the bottom and can walk on the photovoltaic panels. The walking robot 1 is existing technology and will not be described in detail. Multiple support arms 2 are fixedly connected to the outside of the walking robot 1 in a circumferentially equidistant manner. Each support arm 2 is fixedly connected to the end of an installation cylinder 3. A drive motor 4 is fixedly connected inside the mounting cylinder 3, and the output end of the drive motor 4 is connected to the fixed cylinder 6 through a rotating shaft 5. The fixed cylinder 6 is equipped with a detachable cleaning component, which includes a rotating disk 7 and a cleaning brush 8 fixedly connected to the bottom; A magnetic positioning assembly is provided between the rotating disk 7 and the fixed cylinder 6. The magnetic positioning assembly includes a magnet block 9 and a magnet ring 10. The magnet blocks 9 are equidistantly arranged on the top of the rotating disk 7, and the magnet ring 10 is correspondingly arranged on the fixed cylinder 6. The magnet blocks 9 and the magnet ring 10 are positioned and fixed by magnetic attraction. The magnetic positioning assembly between the rotating disk 7 and the fixed cylinder 6, in which the magnetic attraction between the magnet blocks 9 and the magnet ring 10 replaces the traditional bolt fastening method, realizes tool-free quick disassembly and assembly of the cleaning components, shortens the replacement time of the cleaning components, and reduces the downtime maintenance frequency of the cleaning robot.

[0021] In this embodiment, as Figure 2 and Figure 4 As shown, the side wall of the fixed cylinder 6 is provided with an axial locking assembly. The locking assembly includes a cylinder 1101 and a movable plate 1103. The cylinder 1101 is fixedly connected to the fixed cylinder 6, and the movable plate 1103 is disposed inside the cylinder 1101. A locking rod 1104 is connected to one side of the movable plate 1103. The outer wall of the rotating disk 7 is provided with a ring array of locking holes 12, and the output end of the locking rod 1104 is movably inserted into the locking holes 12. The locking rod 1104 and the locking holes 12 on the outer side of the rotating disk 7 are connected to form a double fixing structure, which adds a mechanical locking function to the magnetic positioning, effectively preventing the cleaning components from falling off unexpectedly due to equipment vibration or external impact, and improving the safety of operation.

[0022] In this embodiment, as Figure 4 As shown, the outer side of the cylinder 1101 has an opening, and a cover plate 1102 is fixedly connected to the opening. A thrust spring 1106 abuts against the inner side of the cover plate 1102, and the other end of the thrust spring 1106 abuts against the moving plate 1103. The rebound force of the thrust spring 1106 drives the locking rod 1104 to maintain a thrust towards the locking hole 12 at all times, preventing the cleaning component from falling off unexpectedly.

[0023] In this embodiment, as Figure 4 As shown, a connecting rod 1105 is fixedly connected to the other side of the movable plate 1103. The connecting rod 1105 passes through the through hole of the cover plate 1102 and extends to the outside. A pull plate 1107 is fixedly connected to the end of the connecting rod 1105. By pulling the pull plate 1107, the locking rod 1104 can be moved outward and disengaged from the locking hole 12, which facilitates the quick disassembly and assembly of the cleaning components.

[0024] In this embodiment, as Figure 4As shown, a positioning rod 1108 is fixedly connected to the inner wall of the cylinder 1101, and a corresponding positioning hole is provided on the moving plate 1103. The positioning rod 1108 and the positioning hole form a sliding fit to ensure the stability of the axial movement of the moving plate 1103.

[0025] In this embodiment, as Figure 1 and Figure 5 As shown, the walking robot 1 is equipped with a spraying component. The spraying component includes a detachable water tank 13 inside the walking robot 1. A water pump is connected to the water outlet of the water tank 13. A ring-shaped mounting strip 14 is connected to the water outlet of the water pump. Multiple nozzles 15 are arranged in a ring array on the outer side of the mounting strip 14. The spraying direction of the nozzles 15 forms a predetermined angle with the working surface of the cleaning brush 8. The predetermined angle is 30 to 60°, which allows the water flow to impact the cleaning brush 8 and the working surface. This improves the cleaning effect on the surface of the photovoltaic panel while avoiding water splashing. Compared with traditional fixed nozzle spraying cleaning, it improves cleaning efficiency and water resource utilization.

[0026] In this embodiment, the water tank 13 is equipped with a liquid level detection sensor. The liquid level detection sensor is an EE-SPX303-W2L type photoelectric liquid level sensor. When the liquid level is lower than the threshold, the automatic return program of the walking robot 1 is triggered.

[0027] In this embodiment, a photovoltaic panel edge detection device is provided on the outside of the walking robot 1. The photovoltaic panel edge detection device is an infrared ranging sensor. The infrared ranging sensor is a Sharp GP2Y0A21YK0F. The infrared ranging sensor can monitor the change in distance from the photovoltaic panel in real time, identify the boundary of the work area, trigger the anti-fall protection and automatically adjust the travel path to avoid the risk of the cleaning robot falling.
