Technical Field

[0001] The utility model belongs to the field of photovoltaic panel cleaning equipment, and particularly relates to a water circulation photovoltaic panel cleaning vehicle. Background Art

[0002] Photovoltaic panels have been widely used as clean energy equipment. However, since photovoltaic panels are in an outdoor environment, dust is likely to accumulate on the surface of the photovoltaic panels. During the operation of the photovoltaic panels, the dust on the surface of the photovoltaic panels will seriously affect the working efficiency of the photovoltaic panels. Therefore, it is necessary to clean regularly to keep the surface of the photovoltaic panels clean and avoid reducing the working efficiency of the photovoltaic panels.

[0003] Currently, most of the machines used for cleaning the surface of photovoltaic panels clean by water flushing and the rotation of cleaning rollers. However, this cleaning method will cause the water after cleaning to flow away directly, wasting water resources. Moreover, a water supply pipe needs to be connected to the machine, which is not conducive to the movement and cleaning of the machine. Content of the Utility Model

The length direction of the water spraying pipe is parallel to the length direction of the cleaning rollers. Water spraying nozzles are arranged on the water spraying pipe. The water spraying pipe is located in front of the cleaning roller far from the vehicle body.

[0008] Further, the water recycling assembly includes a water return pipe, a water return pump, and a filtration tank. The number of the water return pipes and the water return pumps is two. One ends of the two water return pipes are correspondingly connected to the water inlet of the two water return pumps. Branch pipes respectively communicating with the ends of the two collection grooves are arranged at the other ends of the two water return pipes. The water outlets of the two water return pumps are connected to the sewage inlet of the filtration tank. The clean water outlet of the filtration tank is connected to the water inlet of the fresh water tank.

[0009] Further, the two cleaning rollers are in transmission connection with each other, and a driving motor connected to any one of the cleaning rollers is arranged on the fixed frame.

[0010] Further, a controller is provided on the vehicle body, and the water pump, the return water pump, and the drive motor are all electrically connected to the controller.

[0025] Embodiment 1

[0026] As shown in Figures 1 - 5 the figure, a water circulation photovoltaic panel cleaning vehicle includes a fixing frame 2 installed at the front end of the vehicle body 1. Two cleaning rollers 3 that rotate relative to each other and are parallel to the front end of the vehicle body 1 are installed inside the fixing member. A recovery cover 4 connected to the fixing frame 2 is installed above the two cleaning rollers 3. An inverted V-shaped collecting plate 5 located above the two cleaning rollers 3 is provided on the recovery cover 4. Collecting grooves 6 are installed at both bottom ends of the collecting plate 5. A water spraying assembly and a water recovery assembly are installed on the vehicle body 1. The water spraying assembly is used to spray water on the photovoltaic panel, and the water return assembly is communicated with the collecting groove 6 to recover the water in the collecting groove 6.

[0027] Specifically, the water spraying assembly includes a fresh water tank 7 installed on the vehicle body 1, a water pump 8 communicated with the fresh water tank 7, and a water spraying pipe 9 communicated with the water pump 8. The length direction of the water spraying pipe 9 is parallel to the length direction of the cleaning roller 3. Water spraying ports are opened on the water spraying pipe 9. The water spraying pipe 9 is located in front of the cleaning roller 3 far from the vehicle body 1. Among them, the water inlet of the water pump 8 is communicated with the water outlet of the fresh water tank 7, and the water outlet of the water pump 8 is communicated with the water spraying pipe 9. In this embodiment, the water spraying pipe 9 is located inside the recovery cover 4, and the water spraying ports of the water spraying pipe 9 face the photovoltaic panel. As another implementation manner, the water spraying direction of the water spraying ports of the water spraying pipe 9 can be tangent to the cleaning roller 3. As another implementation manner, the water spraying direction of the water spraying ports of the water spraying pipe 9 can face the cleaning roller 3.

[0028] The water return assembly includes a water return pipe 10, a water return pump 11, and a filtering box 12. The number of the water return pipe 10 and the water return pump 11 is two. One ends of the two water return pipes 10 are correspondingly communicated with the water inlets of the two water return pumps 11. The other ends of the two water return pipes 10 are both communicated with branch pipes 13 respectively communicated with the ends of the two collecting grooves 6. The other ends of the two water return pipes 10 respectively correspond to the ends of the two collecting grooves 6. One end of the water return pipe 10 is communicated with the water inlet of the water return pump 11, and the other end of the water return pipe 10 is provided with branch pipes 13 respectively communicated with both ends of the collecting groove 6. The water outlet of the water return pump 11 is communicated with the sewage inlet of the filtering box 12, and the clean water outlet of the filtering box 12 is communicated with the water inlet of the fresh water tank 7.

[0029] In this embodiment, for the convenience of the two cleaning rollers 3 to work, the two cleaning rollers 3 are connected by gear transmission. A driving motor 14 is installed on the fixing frame 2 and is drivingly connected to any one of the cleaning rollers 3. One driving motor 14 is used to drive the two cleaning rollers 3 to rotate relatively. The cleaning roller 3 away from the vehicle body 1 is used for pre-cleaning the surface of the photovoltaic panel, and the cleaning roller 3 close to the vehicle body 1 is used for secondary cleaning of the surface of the photovoltaic panel. Through the relative rotation of the two cleaning rollers 3, the cleaned sewage is thrown upward onto the collecting plate 5, and then drained into the collecting tank 6 through the structure of the collecting plate 5, facilitating the recycling of the sewage by the water return assembly.

[0030] It should be noted that in this embodiment, the vehicle body 1 is a remote control vehicle.

[0031] Working principle: When cleaning the photovoltaic panel, place the vehicle body 1 on the photovoltaic panel, turn on the water spraying assembly, the driving motor 14 and the water return assembly. The surface of the photovoltaic panel is wetted by the water spraying assembly, and the driving motor 14 drives the two cleaning rollers 3 to rotate relatively. At the same time, the vehicle body 1 moves forward. During the movement of the vehicle body 1, the two cleaning rollers 3 rotate to clean the photovoltaic panel and throw the sewage onto the collecting plate 5 during the rotation. Under the action of gravity, the sewage on the collecting plate 5 flows into the collecting tank 6. The water return pump 11 in the water return assembly works to transport the sewage in the collecting tank 6 to the filtering box 12 for filtering, and the filtered water returns to the clean water tank 7 for recycling.

[0032] Combined with the above, the present application recycles the sewage during the cleaning process of the photovoltaic panel through the cleaning roller 3, the recovery cover 4, the water spraying assembly and the water return assembly, and circulates the water used for cleaning the photovoltaic panel. It does not need to be connected to the water supply pipe, and also avoids wasting water resources, effectively solving the problem of water resource waste in the current cleaning machine for the surface of photovoltaic panels.
