Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning technology, specifically a cleaning device for solar photovoltaic panels. Background Technology

[0002] Solar photovoltaic panels are exposed to the elements for extended periods, and dust and other debris tend to accumulate on their surfaces after prolonged use, significantly impacting their efficiency in converting solar energy. Therefore, it is necessary to clean solar photovoltaic panels regularly.

[0003] According to CN221828880U, a cleaning device for solar photovoltaic panels is disclosed. This technology discloses "a cleaning device for solar photovoltaic panels, belonging to the field of photovoltaic panel cleaning technology. It mainly includes a base, support plate, motor, controller, sensor, active pulley, driven pulley, belt, sliding mechanism, bearing seat, rotating shaft, cleaning brush, crossbeam, and scraper." The device features the following technical benefits: "When the solar photovoltaic panel needs cleaning, water is manually supplied to the panel. The operator adjusts the controller, which starts the motor. The motor drives the active pulley to rotate, which in turn drives the driven pulley and belt to rotate. With the assistance of the sensor, the cleaning brush on the sliding mechanism reciprocates, cleaning dust and debris from the solar photovoltaic panel. The scraper wipes away residual water, reducing the labor intensity of the workers, improving cleaning efficiency, and saving cleaning time."

[0004] The above solution cleans the photovoltaic panel by driving the cleaning brush on the sliding mechanism to reciprocate. However, since the cleaning brush is rotatably mounted on the sliding mechanism, the sliding mechanism moves and drives the cleaning brush to rotate. This results in the combined motion of rotation and sliding, which may cause uneven contact between the cleaning brush and the surface of the photovoltaic panel, affecting the cleaning quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cleaning device for solar photovoltaic panels. The cleaning mechanism can simultaneously brush the surface of the photovoltaic panel while moving, and both movement and brushing can be controlled by a single motor. Furthermore, the brush head oscillates back and forth during the brushing process, resulting in a more thorough cleaning of the photovoltaic panel surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for a solar photovoltaic panel, comprising a photovoltaic panel, wherein a cleaning mechanism is provided on the photovoltaic panel for cleaning the surface of the photovoltaic panel, the cleaning mechanism comprising:

[0007] The movable component includes a frame disposed on the left and right sides of the photovoltaic panel, and an active pulley rotatably mounted on the upper part of the frame;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution for a cleaning device for solar photovoltaic panels: a cleaning device for solar photovoltaic panels includes a photovoltaic panel 1, and a cleaning mechanism 2 is provided on the photovoltaic panel 1 for cleaning the surface of the photovoltaic panel 1. The cleaning mechanism 2 includes:

[0025] The movable component 21 includes a frame 211 disposed on the left and right sides of the photovoltaic panel 1, and an active pulley 212 rotatably mounted on the upper end inside the frame 211.

[0026] The brushing assembly 22 includes a bracket 221 rotatably mounted on the upper end of the inner wall of the housing 211, a crossbar 222 fixed between the lower ends of the left and right brackets 221, a brush head 223 fixed at the bottom of the crossbar 222, a disc 224 rotatably mounted on the inner wall of the housing 211 and fixedly connected to the drive pulley 212, and a cam 225 rotatably mounted on the outer edge of the disc 224 and located inside the bracket 221.

[0027] Supply component 23 is mounted on the movable component 21 and is used to provide cleaning fluid when cleaning photovoltaic panel 1.

[0028] In this embodiment, the output end of the motor 25 drives the drive pulley 212 to rotate the disc 224. When the disc 224 rotates, the cam 225 drives the bracket 221 to swing back and forth, so that the bracket 221 drives the brush head 223 on the crossbeam 222 to clean the surface of the photovoltaic panel 1.

[0029] Specifically, the moving component 21 also includes driven pulleys 213 rotatably mounted on both sides inside the housing 211, belts 214 installed between the driven pulleys 213 on both sides and the driving pulley 212, and upper guide wheels 215 rotatably mounted on both sides of the inner wall of the housing 211 and fixedly connected to the driven pulleys 213.

[0030] In this embodiment, when the driving pulley 212 rotates, the belt 214, in conjunction with the driven pulley 213, drives the upper guide wheel 215 to rotate. With the cooperation of the lower guide wheel 217, the upper guide wheel 215 drives the cleaning mechanism 2 to move along the photovoltaic panel 1.

[0031] Specifically, the movable component 21 also includes a movable frame 216 slidably mounted inside the lower end of the housing 211, lower guide wheels 217 rotatably mounted on both sides of the inner wall of the movable frame 216, a bushing nut 218 rotatably mounted inside the middle of the movable frame 216, and a screw 219 fixed in the middle of the bottom of the housing 211, with the screw 219 threadedly installed with the bushing nut 218. In this embodiment, by adjusting the rotation of the bushing nut 218 with a wrench, the lower guide wheels 217 on the movable frame 216 are raised and lowered via the screw 219, thereby detaching the cleaning mechanism 2 from the photovoltaic panel 1.

[0032] Specifically, the supply component 23 includes a water tank 231 disposed above the brush head 223, a fixing bracket 232 fixed on both sides of the bottom of the water tank 231, a water pipe 233 fixed between the two fixing brackets 232, a water pump 234 installed between the water tank 231 and the water pipe 233, and several hoses 235 connected to the lower end of the water pipe 233, with the lower end of the hoses 235 connected to the brush head 223.

[0033] In this embodiment, the cleaning solution in the water tank 231 is pumped to the water pipe 233 by the water pump 234, and then enters the brush head 223 through multiple hoses 235 to evenly wet it.

[0034] Specifically, the cleaning mechanism 2 also includes a cover 24 fixed between the two side frames 211, and the water tank 231 is fixed inside the cover 24.

[0035] In this embodiment, the cover 24 can shield the supply component 23 and brush head 223 below, and seal the inside of the housing 211 to reduce the corrosion caused by the external environment.

[0036] Specifically, the cleaning mechanism 2 also includes a motor 25 installed on the outer wall of one end of the cover 24, and the output end of the motor 25 is fixed to the drive pulley 212.

[0037] In this embodiment, the brushing and walking of the cleaning mechanism 2 can be driven by only one motor 25.

[0038] The working principle and usage process of this utility model are as follows: First, the output end of the motor 25 drives the active pulley 212 to rotate. When the active pulley 212 rotates, it drives the upper guide wheel 215 to rotate through the belt 214 and the driven pulley 213. The upper guide wheel 215 drives the cleaning mechanism 2 to move along the photovoltaic panel 1 with the cooperation of the lower guide wheel 217.

[0039] Simultaneously, the rotation of the drive pulley 212 also drives the disc 224 to rotate. The rotation of the disc 224, via the cam 225, causes the bracket 221 to oscillate reciprocally, allowing the bracket 221 to drive the brush head 223 on the crossbeam 222 to clean the surface of the photovoltaic panel 1. Simultaneously, the water pump 234 pumps the cleaning solution from the water tank 231 into the water pipe 233, which then enters the brush head 223 through multiple hoses 235 to evenly wet it, enabling a more thorough cleaning of the photovoltaic panel 1 surface.
