[0002] The principle of photovoltaic power generation is derived from the photoelectric effect of semiconductors, but it is greatly affected by the environment. Long-term dust accumulation will greatly reduce the power generation efficiency of photovoltaic modules. When cleaning photovoltaic panels, a cleaning device that can move along the photovoltaic panels is used.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, a photovoltaic panel cleaning device comprises a bracket 1, on which a photovoltaic panel 2 is mounted, and a spray pipe 3, at the bottom of which spray heads 4 are evenly arranged, on which a water inlet port 5 is arranged, and at both ends of the spray pipe 3, connecting parts are respectively arranged, and the connecting parts comprise a side plate 6 mounted on the end of the spray pipe 3, and the side plate 6 has a mounting groove 7, on which rollers 8 are respectively arranged on both sides of the mounting groove 7, and a first motor 9 is arranged on the outer surface of the mounting groove 7, and the output end of the first motor 9 is fixedly connected to one of the rollers 8, and at both ends of the bracket 1, guide rails 10 matching with the rollers 8 in the mounting groove 7 are respectively arranged, and the lower surface of the mounting groove 7 abuts against the guide rails 10, and the upper surface of the spray pipe 3 is symmetrically provided with fixing seats 11, and the two fixing seats 11 are symmetrically provided with fixing seats 12. 1 is provided with a lead screw 12, a second motor 13 for driving the lead screw 12 to rotate is provided on one side of one of the fixed seats 11, a slider 14 is threadedly connected to the lead screw 12, the slider 14 is slidably connected to the spray pipe 3, side rods 15 are provided on both sides of the slider 14, a swing rod 16 is rotatably connected to the side rod 15, a scraper 17 is provided at the bottom of the swing rod 16, the cleaning areas of the scrapers 17 located on both sides of the slider 14 overlap, an extension plate 18 is provided on the side rod 15, a bottom plate 19 is provided on the swing rod 16, a V-shaped spring 20 is provided between the extension plate 18 and the bottom plate 19, an electric telescopic device 21 is provided on the slider 14, and also includes a connecting rope 22, and the bottom plate 19 and the electric telescopic device 21 are connected by the connecting rope 22.

[0019] The water inlet port 5 of the spray pipe 3 is connected to an external water supply pipe to facilitate the delivery of cleaning water to the spray pipe 3. Two rows of spray heads 4 are symmetrically arranged on the lower surface of the spray pipe 3. When in use, the spray head 4 located at the top sprays first, and then the remaining spray heads 4 start spraying in turn. When the spraying time of the spray head 4 reaches the set time, the spray head 4 stops spraying. By controlling the spraying sequence of the spray heads 4 and controlling the spraying time of the spray heads 4, the waste of water resources can be reduced. At the same time, it can also prevent the photovoltaic panel 2 from being flushed for a long time by the spray head 4 below, causing waste of water resources.

[0020] After completing the local cleaning of the photovoltaic panel 2, it is necessary to quickly remove the water stains on the photovoltaic panel 2 from the photovoltaic panel 2. Specifically, by starting the second motor 13, the second motor 13 drives the lead screw 12 to rotate. Through the threaded connection between the lead screw 12 and the slider 14, and the sliding connection between the slider 14 and the spray pipe 3, the slider 14 can be controlled to make a linear motion along the lead screw 12. When the slider 14 moves, the side rod 15 is driven to move, and the swing rod 16 and the scraper 17 are driven to move. Since the extension plate 18 is fixedly connected to the side rod 15, through the elasticity of the V-shaped spring 20, through the cooperation of the extension plate 18, the bottom plate 19 and the V-shaped spring 20, the bottom of the scraper 17 can be abutted against the outer surface of the photovoltaic panel 2, and the scraper 17 moves obliquely from top to bottom along the photovoltaic panel 2, so that the water stains on the photovoltaic panel 2 can be scraped off from the photovoltaic panel 2. Since the two scrapers 17 have overlapping working areas and the two scrapers 17 are staggered, the scraper 17 can scrape the water stains on the photovoltaic panel 2 more cleanly and thoroughly.

[0021] After completing the scraping of water stains on the upper surface of the photovoltaic panel 2, in order to facilitate the subsequent scraping again, the scraper 17 needs to be restored to the initial position. Specifically, the output end of the electric telescopic device 21 is controlled to extend, and the output end of the electric telescopic device 21 drives the bottom plate 19 to move through the connecting rope 22, and then drives the scraper 17 to move, so that the scraper 17 is separated from the photovoltaic panel 2. At this time, the V-shaped spring 20 is further compressed, and then the second motor 13 is controlled to rotate in the opposite direction to drive the scraper 17 to return to the initial position. In the initial position, the scraper 17 does not contact the outer surface of the photovoltaic panel 2, and only when the spray head 4 sprays and cleans the area where the scraper 17 is located, the electric telescopic device 21 is controlled to retract its output end, and under the action of the V-shaped spring 20, the scraper 17 is abutted against the photovoltaic panel 2 to facilitate continued cleaning of the photovoltaic panel 2.

[0022] When spraying the next area, the first motors 9 at both ends of the spray pipe 3 are started, and the two first motors 9 rotate synchronously and drive the roller 8 to rotate. Through the cooperation of the roller 8 and the guide rail 10, the position of the spray pipe 3 on the bracket 1 is moved. At the same time, the guide rail 10 can also support the mounting groove 7 to improve the movement stability of the spray pipe 3.

[0023] Furthermore, a cross bar 23 is provided at the output end of the electric telescopic device 21, one end of the connecting rope 22 is fixedly connected to the bottom plate 19, and the other end of the connecting rope 22 is fixedly connected to one end of the cross bar 23. The output end of the electric telescopic device 21 drives the cross bar 23 to move, and the cross bar 23 drives the scraper 17 to move through the connecting rope 22.

[0024] Furthermore, a slot is provided on the extension plate 18 , a fixed pulley 24 is provided inside the slot, and one end of the connecting rope 22 is fixedly connected to one end of the cross bar 23 after passing around the fixed pulley 24 .

[0025] Furthermore, a water receiving trough 25 is provided on one side of the bracket 1. The sewage generated when cleaning the photovoltaic panel 2 flows into the water receiving trough 25 through the photovoltaic panel 2. One end of the water receiving trough 25 is closed, and the other end can be transported to the water reservoir through a pipeline, or directly discharged into the water reservoir. After sedimentation and filtration, it is convenient for reuse.

[0026] Furthermore, when the scraper 17 moves downward along the photovoltaic panel 2 , the angle between the scraper 17 and the photovoltaic panel 2 below the scraper 17 is an acute angle, which facilitates reducing the resistance between the scraper 17 and the photovoltaic panel 2 .

[0027] After cleaning the photovoltaic panel 2, the device can promptly remove as much water stains as possible on the photovoltaic panel 2 through the scraper 17, accelerate the evaporation of the water stains on the photovoltaic panel 2, thereby preventing the water stains and dust from forming dried mud spots on the photovoltaic panel 2, improving the cleaning effect of the photovoltaic panel 2, and having a good use effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
