Description

Technical Field

[0001] The utility model relates to the technical field of solar panel cleaning equipment, in particular to a solar panel cleaning structure of a photovoltaic power station. Background Art

[0002] Solar panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. They are the core component of photovoltaic power stations and are responsible for converting solar energy into electrical energy to supply the power system of the power station. In order to ensure the optimal performance and long-term stability of solar panels, their surfaces need to be cleaned regularly.

[0003] Current solar panel cleaning devices generally use scraper technology to remove impurities remaining on the surface of solar panels. However, traditional cleaning scrapers will inevitably be worn during repeated scraping of the solar panel surface, which greatly shortens the service life of the cleaning blade, thereby increasing maintenance costs and replacement frequency. For this reason, we propose a solar panel cleaning structure for a photovoltaic power station. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See attached Figure 1-8 , a solar panel cleaning structure of a photovoltaic power station comprises a bracket 1 and a battery panel 2 arranged thereon, sliders 3 are provided on both sides of the bracket 1 for sliding along the edge thereof, a scraper 4 is provided between the sliders 3 on both sides, the scraper 4 is symmetrically arranged on the upper and lower sides, and its bottom is in contact with the surface of the battery panel 2, and a ratchet assembly 5 is provided at one end of the scraper 4 passing through the slider 3, and a rack 6 is provided on the bracket 1 for rotating with the ratchet assembly 5. When cleaning the surface of the battery panel 2, the slider 3 is driven to slide back and forth on the bracket 1, and at this time, the sliders 3 on both sides drive the scraper 4 to reciprocate back and forth to clean up the impurities attached to the surface of the battery panel 2. During the reciprocating motion of the slider 3, the ratchet assembly 5 will contact the rack 6, and the rack 6 forces the ratchet assembly 5 to rotate 180°, and at this time the scraper 4 will also rotate 180°. When the scraper 4 cleans the surface of the battery panel 2, the upper and lower sides are cleaned alternately, which reduces the wear of the scraper 4 and increases the service life of the scraper 4.

[0028] In this embodiment, a fixed shaft 7 is provided on the bracket 1, and a cleaning plate 8 is symmetrically sleeved on the fixed shaft 7. The symmetrically arranged cleaning plates 8 are connected to the bracket 1 through torsion springs 9, and the blade sides of the symmetrically arranged cleaning plates 8 correspond to the blade positions of the upper and lower sides of the scraper 4 respectively. When the scraper 4 reciprocates to clean the surface of the solar panel 2, the scraper edge of the scraper 4 will contact the blade side of the cleaning plate 8, and the scraper 4 moves close to the cleaning plate 8 and squeezes it. At this time, the cleaning plate 8 is deflected, and its blade side slides along the blade of the scraper 4, and the impurities remaining on the blade of the scraper 4 are scraped off, so that the scraper 4 can better clean the surface of the solar panel 2 and improve the cleaning quality of the scraper 4.

[0029] In this embodiment, the scraper 4 has blade edges symmetrically arranged on the upper and lower sides. The four blade edges of the scraper 4 clean the surface of the solar panel 2 alternately, thereby increasing the service life of the scraper 4 .

[0030] In this embodiment, the ratchet assembly 5 includes a gear 51 meshing with the rack 6. When the ratchet assembly 5 is in motion, the gear 51 rotates when in contact with the rack 6.

[0031] See attached Figure 6-7 A slot body is provided inside the gear 51, and a ratchet groove 52 is provided in the circumferential direction of the slot body. A rotating disk 53 connected to the end of the scraper 4 is rotatably connected in the slot body. A receiving slot 54 for receiving the ratchet teeth 55 is provided in the circumferential direction of the rotating disk 53. The ratchet teeth 55 are arranged in cooperation with the ratchet groove 52, and are rotatably connected in the receiving slot 54, and are connected to the receiving slot 54 through a spring 56. When the gear 51 rotates clockwise, the inclined surface inside the ratchet groove 52 contacts the inclined surface of the ratchet teeth 55, so that the ratchet teeth 55 rotate inside the knife receiving slot 54. At this time, the rotating disk 53 will not rotate with the gear 51, that is, the scraper 4 will not rotate at this time;

[0032] When the gear 51 rotates counterclockwise, the vertical surface inside the ratchet groove 52 contacts the vertical surface of the ratchet tooth 55. At this time, one side of the ratchet tooth 55 will abut against the inner wall of the accommodating groove 54. At this time, the rotating disk 53 will rotate with the gear 51, further causing the scraper 4 to rotate 180°. At this time, the upper and lower sides of the scraper 4 are exchanged, thereby achieving the effect of the four blades of the scraper 4 alternately cleaning the surface of the solar panel 2.

[0033] In this embodiment, screw rods 31 for use with sliders 3 are symmetrically provided on both sides of the bracket 1, and pulleys 32 are provided at the ends of the screw rods 31 on both sides. The pulleys 32 on both sides are connected by belts 33 for transmission. Motors 34 are provided at the ends of the screw rods 31. When the motor 34 is started, the screw rods 31 on both sides rotate synchronously through the belts 33, and the sliders 3 arranged on the surfaces of the screw rods 31 move along the edges of the bracket 1. At this time, the sliders 3 drive the scrapers 4 to clean and remove impurities from the surface of the solar panel 2.

[0034] In this embodiment, a sunshade 10 that semi-shiels the scraper 4 and the pulley 32 is provided on the bracket 1, thereby increasing the service life of the scraper 4 and the pulley 32.

[0035] Working principle: start the motor 34 , and the slider 3 arranged on the surface of the screw rod 31 drives the scraper 4 to move along the edge of the bracket 1 and clean the surface of the solar panel 2 .

[0036] When the scraper 4 moves back and forth to clean the impurities attached to the surface of the solar panel 2, the gear 51 will contact the rack 6. When the gear 51 rotates counterclockwise, the rotating disk 53 will rotate with the gear 51 and make the scraper 4 rotate 180°. At this time, the upper and lower sides of the scraper 4 are exchanged, and the four blades of the scraper 4 alternately clean the surface of the solar panel 2, which reduces the wear of the scraper 4 and increases the service life of the scraper 4.

[0037] When the scraper 4 moves back and forth to clean the surface of the solar panel 2, the scraper edge of the scraper 4 will contact the edge side of the cleaning plate 8, and the edge side of the cleaning plate 8 will scrape off the impurities remaining on the edge of the scraper 4, so that the scraper 4 can better clean the surface of the solar panel 2, ensuring that the scraper 4 can maintain an excellent cleaning effect.
