Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and more specifically, to a self-cleaning structure of a water surface photovoltaic bracket. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. Photovoltaic brackets are commonly used components when installing photovoltaic panels, and play a very important role in ensuring the stability of photovoltaic panels.

[0003] Laying photovoltaic panels on the water surface is a common method of photovoltaic power generation. In order to prevent the photovoltaic panels from directly contacting the water surface, photovoltaic brackets suspended on the water surface are needed to support the photovoltaic panels. When common photovoltaic brackets on the water surface are used to support photovoltaic panels, because there are many water birds living by the water, the water birds are likely to discharge feces on the photovoltaic panels. After being exposed to the sun, the feces will adhere to the surface of the photovoltaic panels, which is not only difficult to peel off, but also affects the power generation efficiency of the photovoltaic panels and causes certain erosion to the photovoltaic panels. Utility Model Content

By installing tempered glass above the photovoltaic panel, bird droppings can be blocked from falling directly on the photovoltaic panel and causing erosion of the photovoltaic panel. The driving component can pull the gear to rotate, so that the gear drives the photovoltaic panel and the tempered glass to flip with the help of the rotating rod. The two first electric push rods can push the tempered glass into the water. In this way, the bird droppings attached to the tempered glass can be soaked in water and peeled off the tempered glass with the help of the cleaning component.

The driving component can pull the gear 8 to rotate, so that the gear 8 drives the photovoltaic panel 5 and the tempered glass 7 to flip with the help of the rotating rod 3. The two first electric push rods 6 can push the tempered glass 7 into the water. In this way, the bird droppings attached to the tempered glass 7 can be soaked in water and peeled off from the tempered glass 7 with the help of the cleaning component, making the cleaning of the tempered glass 7 more convenient, ensuring good light transmittance and providing protection for the photovoltaic panel 5.

[0022] Among them, the driving component includes a fixed block 9, which is fixedly installed on the support plate 2. A second electric push rod 10 is arranged on the fixed block 9. A carrier block 11 is fixedly installed on the output end of the second electric push rod 10. A rack 12 is fixed on the top of the carrier block 11, and the rack 12 is meshed with the gear 8.

[0023] The second electric push rod 10 is used to push the rack 12 to move, and the rack 12 and the gear 8 are meshed with each other, so that the gear 8 can be pulled to rotate.

[0024] Among them, ropes 13 are fixed at the four corners of the bottom of the floating body 1, and counterweight blocks 14 are fixed to the bottom ends of the ropes 13.

[0025] By arranging the counterweights 14 at the four corners of the floating body 1 with the aid of the ropes 13 , the stability of the position of the floating body 1 on the water surface can be well ensured.

[0028] The working principle and use process of this utility model:

[0029] When in use, according to the water depth, cut a rope 13 of appropriate length, so that one end of the rope 13 is tied to the floating body 1, and the other end of the rope 13 is tied to the counterweight 14. Four counterweights 14 are arranged at the four corners of the floating body 1. When the floating body 1 floats on the water surface, the counterweight 14 just touches the bottom. In this way, the stability of the position of the floating body 1 on the water surface can be guaranteed. The photovoltaic panel 5 is installed on the supporting plate 4, and the tempered glass 7 is arranged above the photovoltaic panel 5. The tempered glass 7 is made of high-transmittance tempered glass, which can ensure the normal passage of sunlight and try to avoid affecting the power generation operation of the photovoltaic panel 5.

[0030] Waterfowl near the water are very likely to pull their droppings onto the top of the photovoltaic panel 5. The tempered glass 7 can block the droppings, so that the droppings cannot fall onto the photovoltaic panel 5, thereby preventing the droppings from corroding the photovoltaic panel 5. At night, the second electric push rod 10 is controlled to push the rack 12 to move. With the help of the meshing of the rack 12 and the gear 8, the gear 8 can be pulled to rotate, so that the gear 8 pulls the photovoltaic panel 5 and the tempered glass 7 to flip 180 degrees with the help of the rotating rod 3. At this time, the photovoltaic panel 5 is above the tempered glass 7, and the two first electric push rods 6 are controlled to extend so that the two first electric push rods 6 can turn the tempered glass 7. The tempered glass 7 is pushed into the water for soaking. After soaking for a period of time, the driving motor 19 can be controlled to drive the screw rod 17 to rotate. The screw rod 17 pulls the slider 18 to move back and forth inside the rectangular frame plate 16 in a screw transmission manner, so that the rectangular frame plate 16 pulls the brush plate 21 to move back and forth in the water with the help of the connecting plate 20, and the surface of the tempered glass 7 can be brushed, so that the feces and impurities on the surface of the tempered glass 7 can be peeled off. After that, the first electric push rod 6 and the second electric push rod 10 can be controlled to operate to drive the photovoltaic panel 5 and the tempered glass 7 to reset.
