Detailed implementation manner

[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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art 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 with a fast spraying function, including a support device 3. A displacement device 1 is slidably sleeved on the top of the support device 3. Alignment devices 2 are fixedly installed on both sides of the displacement device 1. The alignment device 2 includes a scraper 13, a positioning spring 14, and a support top frame 15. The scraper 13 is slidably inserted into the inside of the support top frame 15. The positioning spring 14 is symmetrically fixedly installed between the scraper 13 and the support top frame 15. The support device 3 includes a photovoltaic panel 16, a cross bar 17, and a rack 18. The rack 18 is fixedly installed on both sides of the photovoltaic panel 16. The cross bar 17 is fixedly installed at the bottom of the rack 18.

[0021] The displacement device 1 includes a photoelectric inductor 4, a return spring 5, a convex key 6, a support cross frame 7, a nozzle 8, a drive motor 9, a gear 10, a support side frame 11, and an electromagnetic valve 12. The support side frame 11 is fixedly installed at the top of both ends of the support cross frame 7. The drive motor 9 is fixedly installed at both ends inside the support cross frame 7. The gear 10 is fixedly installed at the center of one end of the drive motor 9 close to the support side frame 11. The nozzles 8 are equidistantly fixedly installed on both sides of the electromagnetic valve 12. The electromagnetic valve 12 is fixedly installed at the top of the support cross frame 7. The convex key 6 is slidably inserted into both ends of the bottom of the support cross frame 7. The return spring 5 is symmetrically fixedly installed between the convex keys 6. The photoelectric inductor 4 is fixedly installed at both ends inside the support cross frame 7, and the photoelectric inductor 4 is located above the convex key 6. By starting the drive motor 9 to drive the gear 10 to rotate forward and backward, the support cross frame 7 can reciprocate on the top of the photovoltaic panel 16.

[0022] The support top frame 15 is fixedly installed at the top of both sides of the support cross frame 7. The support side frame 11 is slidably sleeved on the cross bar 17 to ensure that the support cross frame 7 moves in a straight line.

[0023] The gear 10 meshes with the rack 18 to drive the support cross-frame 7 to move.

[0024] Sliding grooves are provided at both ends of the bottom of the support cross-frame 7, and the convex key 6 is located inside the sliding grooves to ensure that the convex key 6 moves up and down in a straight line.

[0025] Both ends of the bottom of the convex key 6 and the scraper 13 are inclined at 45°, and the bottom ends of the convex key 6 and the scraper 13 are aligned with the top end of the photovoltaic panel 16 to improve the contact smoothness between the convex key 6 and the scraper 13 and the photovoltaic panel 16.

[0026] Working principle: During use, first install the photovoltaic panel 16 on the external photovoltaic bracket. Both ends of the electromagnetic valve 12 are connected to the external water pipes. When the surface of the photovoltaic panel 16 needs to be cleaned, start the drive motor 9 to drive the gear 10 to rotate. Through the engagement of the gear 10 with the top of the rack 18, when the gear 10 rotates, it can drive the support cross-frame 7 to displace. The support side-frame 11 is slidably sleeved on the cross-bar 17, ensuring that the support cross-frame 7 moves in a straight line. Subsequently, when the support cross-frame 7 drives the convex key 6 and the scraper 13 to move to contact the top of the photovoltaic panel 16, since both bottom ends of the convex key 6 and the scraper 13 are inclined at 45°, the contact smoothness between the convex key 6 and the scraper 13 and the photovoltaic panel 16 can be improved. Subsequently, when the convex key 6 moves to the top of the photovoltaic panel 16, the convex key 6 will move upward to contact the photoelectric sensor 4, thereby triggering the photoelectric sensor 4 to start the electromagnetic valve 12. When the electromagnetic valve 12 is started, water can be delivered into the nozzle 8. By aligning the nozzle 8 perpendicular to the photovoltaic panel 16, water can be sprayed onto the top of the photovoltaic panel 16, thereby wetting the top of the photovoltaic panel 16. Subsequently, when the support cross-frame 7 drives the scraper 13 on the top of the photovoltaic panel 16, the impurities on the photovoltaic panel 16 can be pushed in one direction, and the impurities on the top of the photovoltaic panel 16 can be removed. Since the rack 18 and the cross-bar 17 are longer than the photovoltaic panel 16, when the support cross-frame 7 displaces to the limit position, it can pass over the top of the photovoltaic panel 16. Moreover, due to the elasticity of the positioning spring 14 and the reset spring 5, the convex key 6 and the scraper 13 can be reset downward, causing the top of the convex key 6 to disengage from the photoelectric sensor 4, so that the electromagnetic valve 12 can be powered off, avoiding continuous water spraying from the nozzle 8 and reducing energy waste. When this device is in use, when the drive motor 9 is started, it can drive the gear 10 to move on the rack 18, enabling the entire support cross-frame 7 to displace on the photovoltaic panel 16. At the same time, when the convex key 6 contacts the top of the photovoltaic panel 16, the electromagnetic valve 12 can be started, so that the nozzle 8 can spray water onto the top surface of the photovoltaic panel 16. Moreover, when the support cross-frame 7 displaces to the top of the photovoltaic panel 16, it can drive the scraper 13 to fit with the top of the photovoltaic panel 16. Thus, when the convex key 6 displaces, it can drive the scraper 13 to scrape off the impurities on the top surface of the photovoltaic panel 16, completing the cleaning work of the surface of the photovoltaic panel 16. And when the convex key 6 moves past the top of the photovoltaic panel 16, the elasticity of the reset spring 5 will drive the convex key 6 to disengage from the photoelectric sensor 4, causing the electromagnetic valve 12 to be powered off and reducing energy waste to 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.
