[0015] Beneficial Effects

[0016] 1. The present invention drives the rotating fan blade to rotate through wind force, and then drives the toggle rod to toggle the follower rod to move, so that the winding wheel reels the winding belt, and then pulls the sliding block to drive the cleaning scraper to move together. The cleaning scraper will scrape the surface of the photovoltaic panel during the movement, so as to remove debris on the surface of the photovoltaic panel and prevent the photovoltaic panel from having a hot spot effect, thereby achieving the effect of automatically cleaning the photovoltaic panel when debris easily falls in the air affects the normal operation of the photovoltaic panel.

[0017] 2. In the process of rotation of the toggle lever of the present invention, it will gradually contact with the adjusting slider. Since the adjusting slider is trapezoidal, the toggle lever will gradually be subjected to a thrust after contacting with the adjusting slider. This force acts on the mounting plate through the toggle lever, and then it will pull the mounting plate to move. The movement of the mounting plate will drive the transmission rod to compress the buffer spring to make it shrink and move. At this time, the toggle lever will gradually separate from the follower rod, so that the force acting on the reset spring disappears. At this time, the reset spring will rebound quickly to drive the cleaning scraper to reset, so as to achieve the effect of automatic reset of the equipment after cleaning is completed. At the same time, if the external wind force is small, the probability of a large amount of debris being rolled up in the surface air is very low. At this time, the small wind force is not enough to stretch the sliding block to deform it, so that the equipment is in its original state when there is no wind and no obstructions, and will not move to cause the cleaning scraper to block the photovoltaic panel and cause a hot spot effect.

[0018] 3. The design of the buffer bag of the present invention can effectively buffer the sliding block during the resetting process of the reset spring, preventing the sliding block from being damaged due to long-term impact or the connection between the sliding block and the cleaning scraper from loosening, thereby improving the service life of the equipment. At the same time, the buffer bag will also spray air through the exhaust nozzle during the process of force contraction, and the air flow will blow toward the surface of the cleaning scraper and the photovoltaic panel, thereby further cleaning the surface of the cleaning scraper and the photovoltaic panel.

[0019] 4. In the process of rotating the toggle rod of the present invention, it will contact with the elastic film and push the elastic film to deform it. After deformation, the elastic film will apply a thrust to the elastic rod, thereby pushing the reflective lens to move, and in this process, the elastic rod will also bounce back and forth, so that the reflective lens will shake while moving up and down, thereby reflecting the light irregularly, which can effectively scare the birds so that the birds will not stay above the photovoltaic panel, reduce the probability of bird droppings dripping on the surface of the photovoltaic panel, and thereby reduce the probability of the hot spot effect.

[0020] 5. In the process of deformation of the elastic film of the present invention, it will simultaneously drive the vibration paddle and the collision ball to move. After the vibration paddle and the collision ball move, under the action of inertia force, the two collision balls will knock back and forth and vibrate, thereby making a sound, further scaring the birds and improving the bird-repelling effect of the device.

[0021] 6. The present invention uses the design of the sponge pad and the cleaning brush so that when the cleaning scraper cleans the photovoltaic panel, the cleaning brush first scrapes away most of the dust and debris, and then performs detailed cleaning through the liquid storage bag, thereby improving the cleaning effect on the surface of the photovoltaic panel and reducing the probability of the hot spot effect.

[0022] 7. In the process of the cleaning scraper moving, the cleaning liquid stored in the liquid storage bag will be injected into the sponge pad through the liquid discharge pipe, so that the sponge pad is moistened, further improving the cleaning effect of the sponge pad on the surface of the photovoltaic panel and preventing the occurrence of the hot spot effect.

[0023] 8. In the present invention, during the movement of the cleaning scraper, under the action of inertia, the counterweight ball will pull the liquid storage bag back and forth through the connecting rope to deform it, thereby allowing the cleaning liquid stored in the liquid storage bag to be discharged smoothly. At the same time, during the movement of the counterweight ball, it will also stir the cleaning liquid in the liquid storage bag to prevent precipitation inside the cleaning liquid, thereby ensuring the normal discharge of the cleaning liquid, thereby ensuring the cleaning effect on the surface of the photovoltaic panel and improving the anti-hot spot effect.

[0024] 9. When the sliding block of the present invention moves, it will simultaneously drive the sliding rod to slide inside the limit shell. When the sliding rod slides to contact the limit stopper, it will first push the limit stopper to rotate. Then, during the resetting process, the limit stopper cannot rotate, so that it will slide along the upper part of the trapezoidal groove under the action of the limit stopper, thereby lifting the sliding block. After the sliding block is lifted, the cleaning scraper will be lifted as well. In this way, the surface of the photovoltaic panel will not be scraped during the resetting process, thereby preventing dust from adhering to the surface of the photovoltaic panel during the resetting of the equipment.

[0025] 10. When the present invention is working, after the toggle rod is rotated to contact the adjusting slider, it will pull the mounting plate to move in the direction close to the photovoltaic panel. The movement of the mounting plate will push the guide rod to move. The movement of the guide rod will drive the pressurizing plug to squeeze the lubricating liquid stored in the liquid storage column. The pressurized lubricating liquid will be sprayed out through the lubrication pipe. The sprayed lubricating liquid will eventually be atomized by the atomizing nozzle and drip into the inside of the protective shell, thereby lubricating the mechanism inside the protective shell, improving the service life of the equipment, and ensuring the cleaning effect of the equipment on the surface of the photovoltaic panel, thereby effectively avoiding the occurrence of the hot spot effect.

After the mounting plate 5 rotates, it will drive the toggle rod 6 to toggle the follower rod 7 to move. At this time, the follower rod 7 will drive the winding wheel 8 to rotate after the toggle rod 6 moves, thereby winding the winding belt 9.

Since the adjusting slider 14 is trapezoidal, the toggle rod 6 will gradually receive a thrust after contacting with the adjusting slider 14. This force acts on the mounting plate 5 through the toggle rod 6, and then it will pull the mounting plate 5 to move, and the movement of the mounting plate 5 will drive The transmission rod 3 compresses the buffer spring 15 to make it contract and move. At this time, the toggle rod 6 will gradually separate from the follower rod 7, so that the force acting on the reset spring 11 disappears.
