Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation devices, in particular to a novel green energy-saving photovoltaic exterior wall device. Background Art

[0002] Photovoltaic exterior wall installation is a technology that converts solar energy into electrical energy. It uses solar energy by installing solar panels on the exterior walls of buildings. This technology has the advantages of being clean, renewable, and environmentally friendly. It can effectively reduce dependence on traditional energy, reduce carbon emissions, and improve energy efficiency. Photovoltaic exterior wall installations have been widely used and promoted at home and abroad, becoming an important means of green building and sustainable development.

[0003] In the skylines of modern cities and villages, photovoltaic exterior wall devices decorate the facades of various buildings with their environmentally friendly and innovative appearance. However, these high-efficiency energy converters are inevitably exposed to the outdoor environment and are subjected to the test given by nature. When bad weather such as dark clouds, wind and sandstorms hit, the dust floating in the air and the debris brought by the wind quietly fall on the surface of these devices, forming a layer of shielding that blocks the light. This not only affects the ability of photovoltaic exterior wall devices to capture sunlight, but also undoubtedly reduces their efficiency in converting sunlight into electrical energy, thus adversely affecting the power generation efficiency. For this reason, we propose a new type of green and energy-saving photovoltaic exterior wall device. Utility Model Content

[0014] Compared with the prior art, the utility model provides a new green energy-saving photovoltaic exterior wall device, which has the following beneficial effects:

[0015] 1. This new green energy-saving photovoltaic exterior wall device inputs water into two groups of sprinkler heads through two groups of water storage barrels, thereby softening the dust on the front of the photovoltaic panel. After rotating the scraper 90 degrees, the water can soften the entire front of the photovoltaic panel. Water can act as a lubricant to reduce the friction between the scraper and the photovoltaic panel, thereby reducing the risk of scratching the surface of the photovoltaic panel.

[0016] 2. This new green energy-saving photovoltaic exterior wall device uses a driving cylinder to drive a scraper to remove dust and other garbage from the front of the photovoltaic panel. Dust covers the surface of the photovoltaic panel, which will block the direct sunlight and reduce the light energy absorbed by the photovoltaic panel, thereby reducing the power generation efficiency. Removing dust can reduce this obstruction, allowing the photovoltaic panel to receive sunlight more effectively and improve the photoelectric conversion efficiency of the photovoltaic panel. The accumulation of dust will increase the working temperature of the photovoltaic panel. Long-term high-temperature operation will accelerate the aging of the photovoltaic panel and reduce its service life. By cleaning the surface of the photovoltaic panel, the working temperature of the photovoltaic panel can be effectively reduced and its service life can be extended.

The end of the water outlet pipe 7 is fixedly connected to a water spray head 8 for moistening the surface of the photovoltaic panel 1. Water is respectively input into the two groups of water outlet pipes 7 through the two groups of water storage barrels 6. The water in the two groups of water outlet pipes 7 is discharged to the front of the photovoltaic panel 1 through the two groups of water spray heads 8. The water flows downward from the gap between the front of the photovoltaic panel 1 and the scraper 15 by gravity, thereby softening the dust on the front of the photovoltaic panel 1.

[0026] The piston rod on the driving cylinder 5 is fixedly connected to the side plate 10, and both ends of the side plate 10 are fixedly connected with an integrated long plate 11 that is perpendicular to the side plate 10. Then the scraper 15 is rotated to the original position on the connecting shaft 14 and the two sets of movable plug rods 16 are reinserted to the two sides of the scraper 15. The driving cylinder 5 is started and the piston rod on the driving cylinder 5 is used to retract it. The side plate 10 drives the two sets of long plates 11 to slide downward through the piston rod.

[0027] The dust scraping assembly includes a connecting plate 13, a connecting shaft 14, a scraper 15 and a slider 17. A connecting plate 13 is fixedly provided on one side corresponding to each other of the two groups of long plates 11. The ends of the two groups of connecting plates 13 extend to the front side of the photovoltaic panel 1 and are fixedly connected with a connecting shaft 14.

A slider 17 is fixedly provided on one side corresponding to each other of the two groups of connecting plates 13. The two groups of connecting plates 13 drive the two groups of sliders 17 to slide downward on both sides of the photovoltaic panel 1 respectively through the movement of the long plates 11. At the same time, the connecting shafts 14 on the two groups of connecting plates 13 drive the scraper 15 to slide downward on the front side of the photovoltaic panel 1 and scrape off the dust, water stains and other garbage on the front side of the photovoltaic panel 1.

[0028] Both sides of the photovoltaic panel 1 are provided with a slide groove 12, and two groups of sliders 17 are respectively slidably engaged in the two groups of slide grooves 12, and the two groups of sliders 17 are respectively slid in the two groups of slide grooves 12 to ensure the stability of the sliders 17 when sliding down. The driving cylinder 5 drives the scraper 15 to remove dust and other garbage from the front of the photovoltaic panel 1. The dust covers the surface of the photovoltaic panel 1, which will block the direct exposure of sunlight, reduce the light energy absorbed by the photovoltaic panel 1, and thus reduce the power generation efficiency. Removing dust can reduce this kind of obstruction, so that the photovoltaic panel 1 can receive sunlight more effectively, and improve the photoelectric conversion efficiency of the photovoltaic panel 1. The accumulation of dust will increase the working temperature of the photovoltaic panel 1. Long-term high-temperature work will accelerate the aging of the photovoltaic panel 1 and reduce its service life.

Both ends of the movable rods 16 extend out of the two sides of the connecting plate 13. One end of the two groups of movable rods 16 is movably connected to the two sides of the scraper 15. When there is a lot of dust on the front of the photovoltaic panel 1 and needs to be cleaned, the two groups of movable rods 16 are pulled outward to make the two groups of movable rods 16 separate from the two sides of the scraper 15, and the scraper 15 is rotated ninety degrees on the connecting shaft 14 so that the scraper 15 is rotated from a horizontal state to a vertical state.

[0030] A collection box 9 for collecting dust, water stains and other garbage is fixedly provided at the bottom of the photovoltaic panel 1. The water stains, dust and other garbage on the front of the photovoltaic panel 1 are all scraped off and collected in the collection box 9 to prevent the water stains and dust from falling downwards and causing safety hazards to passers-by.

[0031] Working principle: When there is a lot of dust on the front of the photovoltaic panel 1 and it needs to be cleaned, pull out the two sets of movable rods 16 to separate the two sets of movable rods 16 from the two sides of the scraper 15, and rotate the scraper 15 90 degrees on the connecting shaft 14 to rotate the scraper 15 from the horizontal state to the vertical state, and then input water into the two sets of water outlet pipes 7 through the two sets of water storage barrels 6, and the water in the two sets of water outlet pipes 7 is discharged to the front of the photovoltaic panel 1 through the two sets of water spray heads 8. The water flows downward from the gap between the front of the photovoltaic panel 1 and the scraper 15 by gravity, thereby softening the dust on the front of the photovoltaic panel 1, and then rotate the scraper 15 to the original position on the connecting shaft 14 and connect the two sets of water outlet pipes 7 to the front of the photovoltaic panel 1. The movable plug rod 16 is reinserted into both sides of the scraper 15, and the driving cylinder 5 is started to retract it by using the piston rod on the driving cylinder 5.
