DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present invention: a photovoltaic panel cleaning device convenient for control, including a support device 3. Both sides of the support device 3 are slidably sleeved with an oil displacement device 1. A positioning device 2 is fixedly installed at the rear end of the displacement device 1. The displacement device 1 includes a return spring 4, a sliding key 5, a scraping blade 6, a displacement cross frame 7, side plates 8, movable rods 9 and positioning brackets 10. The side plates 8 are fixedly installed at both ends of the displacement cross frame 7. The sliding keys 5 are symmetrically and fixedly installed inside the side plates 8. The positioning brackets 10 are fixedly installed at the top ends of the side plates 8. The movable rods 9 are symmetrically slidably inserted into the inner parts of the top ends of the positioning brackets 10. The scraping blade 6 is fixedly installed at the bottom end of the movable rod 9. The return springs 4 are symmetrically fixedly installed between the scraping blade 6 and the positioning brackets 10.

[0021] The positioning device 2 includes a nozzle 11, an electromagnetic valve 12 and a connecting pipe 13. The electromagnetic valve 12 is fixedly installed at both top ends of the nozzle 11. The connecting pipe 13 is fixedly installed inside the nozzle 11 and the electromagnetic valve 12. There is an electrical connection between the electromagnetic valve 12 and a photoelectric sensor 16, so that the photoelectric sensor 16 can open the electromagnetic valve 12.

[0022] The support device 3 includes side frames 14, a photovoltaic panel 15, a photoelectric sensor 16, a lead screw 17 and a driving motor 18. The driving motor 18 is fixedly installed at the rear end of the bottom of the photovoltaic panel 15. The lead screw 17 is fixedly installed at the center of the front end of the driving motor 18. The side frames 14 are fixedly installed on both sides of the photovoltaic panel 15. The photoelectric sensor 16 is fixedly installed on both sides of the bottom of the photovoltaic panel 15. A support frame is fixedly installed at the center of the bottom ends of the side frames 14 and the photovoltaic panel 15, so as to facilitate the support and installation of the lead screw 17 and the driving motor 18.

[0023] The electromagnetic valve 12 is fixedly installed at the rear end of the positioning bracket 10. The displacement cross frame 7 is threadedly sleeved on the outer ring of the lead screw 17. When the lead screw 17 rotates, it can drive the displacement cross frame 7 to move.

[0024] The side frame 14 is 10 cm longer than the photovoltaic panel 15, allowing the displacement cross frame 7 and the nozzle 11 to move out of alignment with the top end of the photovoltaic panel 15.

[0025] The connecting pipe 13 communicates with the nozzle 11. The inner sides of the side plates 8 are in contact with both sides of the side frames 14, allowing the displacement cross frame 7 to move in a straight line.

[0026] Working principle: During use, first install the photovoltaic panel 15 on the external photovoltaic bracket so that the photovoltaic panel 15 can perform the work of light energy absorption. When the surface of the photovoltaic panel 15 needs to be cleaned, connect the connecting pipe 13 to the external water valve, keep the water valve in the normally open state, turn on the driving motor 18 to drive the screw rod 17 to rotate. Since the displacement cross frame 7 is threadedly sleeved on the screw rod 17, when the screw rod 17 rotates counterclockwise, it can drive the displacement cross frame 7 to move upward along the surface of the photovoltaic panel 15. The displacement cross frame 7 can move linearly by sliding the sliding key 5 into the chute inside the side frame 14 away from the side end of the photovoltaic panel 15. At the same time, when the displacement cross frame 7 drives the wiper 6 to fit with the top surface of the photovoltaic panel 15, the side plate 8 can fit with the photoelectric sensor 16. Since the photoelectric sensor 16 is electrically connected to the electromagnetic valve 12, the photoelectric sensor 16 can activate the electromagnetic valve 12, causing the water inside the connecting pipe 13 to flow into the nozzle 11. Since the nozzle 11 is vertically aligned with the photovoltaic panel 15, the water can be sprayed onto the surface of the photovoltaic panel 15 to pre-wet the surface of the photovoltaic panel 15. Subsequently, when the wiper 6 moves to the top surface of the photovoltaic panel 15, the dust on the photovoltaic panel 15 can be scraped off, completing the cleaning work of the surface of the photovoltaic panel 15. At the same time, the elasticity of the return spring 4 will drive the wiper 6 to always move downward, thereby improving the tightness of the fit between the wiper 6 and the photovoltaic panel 15. When the surface of the photovoltaic panel 15 is cleaned, the driving motor 18 can be turned on again to drive the screw rod 17 to rotate clockwise, so that the displacement cross frame 7 returns. When the displacement cross frame 7 is completely reset, it can move to contact the end of the side frame 14 away from the driving motor 18. Since the side frame 14 is 10 cm longer than the photovoltaic panel 15, after the displacement cross frame 7 is reset, a gap can be formed between the displacement cross frame 7 and the photovoltaic panel 15 to prevent the displacement cross frame 7 and the nozzle 11 from interfering with the photovoltaic panel 15 when not in use. Moreover, when the displacement cross frame 7 is reset, it can drive the side plate 8 to move away from contact with the photovoltaic panel 15, causing the electromagnetic valve 12 to lose power and the nozzle 11 to stop spraying water, thus preventing waste of water resources. This device drives the screw rod 17 to rotate forward and backward by turning on the driving motor 18, so that the displacement cross frame 7 can drive the wiper 6 and the nozzle 11 to reciprocally move on the photovoltaic panel 15, thereby conveniently controlling the wiper 6 and the nozzle 11 to clean the surface of the photovoltaic panel 15 and complete the work.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
