Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic panels, and in particular to a solar photovoltaic panel cleaning device. Background Art

[0002] Solar photovoltaic panels use the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity.

[0003] The surface cleanliness of solar photovoltaic panels affects their photovoltaic efficiency, so the surface of solar panels needs to be cleaned after production.

[0004] A Chinese patent with application number 202110147963.4 discloses a cleaning device for solar energy production, including a bracket and a clamping device and a cleaning device installed on the bracket. The bracket includes a base and support plates installed on both sides of the base. The support plates are provided with support rods for fixing each other at the corresponding outer ends on both sides. The clamping device is convenient for docking with a conveyor. The solar panels transported by the conveyor are fixed by sliding through a fixed seat. The clamping seat presses down to fix the solar panels. The cleaning device rises to clean one side of the solar panel. The servo motor drives the frame to rotate and flip the solar panel. The cleaning device rises to clean the other side of the solar panel. After cleaning, the cleaning device descends, and the frame of the solar panel is moved out by rotating the cleaning rubber roller. The cleaning rubber roller cleans the frame of the solar panel at the same time. The device is convenient for docking with the conveyor to realize automatic cleaning, improve cleaning efficiency, and can achieve multi-sided cleaning without dead angles.

[0005] However, in actual use, the speed of flipping the solar panel is slow, which makes the entire processing time too long, resulting in low production efficiency of solar photovoltaic panels.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the invention

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 4 As shown, the solar photovoltaic panel cleaning device of the present invention comprises: a frame 1, a feed track and a discharge track installed on the frame 1, and a cleaning component arranged between the feed track and the discharge track.

[0028] The cleaning assembly includes: a lower cleaning roller 2, an upper cleaning roller 3, a motor 4 that drives the lower cleaning roller 2 to rotate, and the motor 4 is preferably a speed-regulating motor 4; a driving assembly that drives the upper cleaning roller 3 away from or close to the lower cleaning roller 2; the rotating shaft of the motor 4 is connected to the lower cleaning roller 2; the driving assembly includes: a fixed frame 5 fixedly mounted on the frame 1, a sliding frame 6 that slides on the fixed frame 5, that is, the sliding frame 6 is slidably mounted on the fixed frame 5, a guide rail slider structure is formed between the fixed frame 5 and the sliding frame 6, the upper cleaning roller 3 is rotatably mounted on the sliding frame 6, and a cylinder 7 that drives the sliding frame 6 to move, and the piston rod of the cylinder 7 is connected to the sliding frame 6.

[0029] By setting up the upper cleaning roller 3 and the lower cleaning roller 2 to clean the solar photovoltaic panel, there is no need to flip the solar photovoltaic panel. Both surfaces of the solar photovoltaic panel can be cleaned at one time, and the cleaning efficiency is high. The cylinder 7 drives the sliding frame 6 to move, and the distance between the upper cleaning roller 3 and the lower cleaning roller 2 can be changed, so as to adapt to different solar photovoltaic panels.

[0030] The motor 4 drives the feed track and the discharging track to operate through a connecting mechanism. The motor 4 drives the lower cleaning roller 2 to rotate on the one hand to clean the solar photovoltaic panel, and drives the feed track and the discharging track to operate on the other hand; thereby, the moving speed of the solar photovoltaic panel and the rotation speed of the cleaning roller can be taken into account, and the cleaning effect is good.

[0031] The feed track includes: a feed drive roller 9, a feed roller 10 and a feed belt line 11; the discharging track includes: a discharging drive roller, a discharging roller and a discharging belt line; the connecting mechanism includes: a main gear 12 installed on the rotating shaft of the motor 4, and a sub-gear 14 installed on the discharging drive roller and the feed drive roller 9, and the main gear 12 is meshed with the sub-gear 14.

[0032] That is, in actual use, the motor 4 drives the lower cleaning roller 2 to rotate, and the motor 4 drives the discharging roller and the feeding roller 10 to rotate through the main gear 12 and the sub-gear 14, thereby further driving the feeding belt line 11 and the discharging belt line to move, and the moving feeding belt line 11 and the discharging belt line drive the solar photovoltaic panels thereon to move.

[0033] The main gear 12 is meshed with the sub-gear 14 via a reduction gear 13, and the reduction gear 13 can reduce the rotation speed, that is, change the rotation speed between the lower cleaning roller 2 and the discharge roller and the feed roller 10, so that they rotate asynchronously. The lower cleaning roller 2 can clean the solar photovoltaic panel at a higher rotation speed, and at the same time, the moving speed of the solar photovoltaic panel is lower, so that the cleaning effect is better.

[0034] The fixed frame 5 is connected to the sliding frame 6 by a hook spring 8, and the hook spring 8 can always pull the upper cleaning roller 3 downward, so that the upper cleaning roller 3 can apply pressure to the solar photovoltaic panel, ensuring that the contact force between the solar photovoltaic panel and the upper cleaning roller 3 and the lower cleaning roller 2 is in a suitable state, thereby ensuring the cleaning effect.

[0035] Finally, it should be added that an auxiliary wheel is rotatably mounted on the frame 1, and the feed belt line 11 and the discharge belt line are sleeved on the auxiliary wheel.

[0036] Working principle:

[0037] The motor 4 drives the lower cleaning roller 2 to rotate, and the motor 4 drives the discharging roller and the feeding roller 10 to rotate through the main gear 12 and the sub-gear 14, thereby further driving the feeding belt line 11 and the discharging belt line to move, and the moving feeding belt line 11 and the discharging belt line drive the solar photovoltaic panels thereon to move, and the solar photovoltaic panels are cleaned by setting the upper cleaning roller 3 and the lower cleaning roller 2, without turning the solar photovoltaic panels over, and the two surfaces of the solar photovoltaic panels can be cleaned at one time, with high cleaning efficiency.
