Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a device for preventing water accumulation in water photovoltaic panels. Background Art

[0002] Photovoltaic panels are power generation devices that convert solar energy into electricity. Their operating principle is based on the photoelectric effect: solar cells convert sunlight into direct current (DC), which is then converted to alternating current (AC) via an inverter. Photovoltaic panels themselves do not generate electromagnetic radiation, thus posing no harm to humans or environmental pollution. However, photovoltaic panels are typically installed on water surfaces. After rain, water accumulates on the panels, affecting their power generation efficiency. Therefore, a device designed to prevent water accumulation on water-based photovoltaic panels is being proposed to prevent this from affecting the panels' performance. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a device for preventing water accumulation of photovoltaic panels on water.

[0004] The technical solution adopted by the utility model to solve its technical problems is a device for preventing water accumulation of photovoltaic panels on water, comprising a spliced ​​float, a support rod, a support frame, a photovoltaic panel, a water removal mechanism and a wall cleaning mechanism. Two first support rods and two second support rods are fixed on the top of the spliced ​​float. The two first support rods and the second support rods are both located between the support frame and the spliced ​​float. The tops of the two first support rods and the second support rods are both connected to the support frame. Two water discharge plates and four photovoltaic panels arranged in a rectangular array are provided on the support frame. A water removal mechanism is provided on the support frame. The water removal mechanism is provided with a wall cleaning mechanism, which includes a truss, a motor, a screw rod, a slide, a rail pad and a scraper. Two trusses are fixed on the support frame, and a motor is fixed on the uppermost truss. The motor output shaft is connected with a screw rod through a coupling, and the end of the screw rod away from the motor is rotatably connected to the lowermost truss. The slide is located between the two trusses, and a screw hole adapted to the screw rod is opened on the slide. A rail pad is fixed on the top of the slide, and scrapers are provided on both sides of the slide. A plurality of springs are fixed on the top of the two scrapers, and the tops of the plurality of springs are connected to the rail pad.

[0005] By adopting the above technical solution, the setting of the drain plate is conducive to the flow of accumulated water. The output shaft of the motor drives the screw to rotate and the slide moves. When the slide moves, the rail pad moves with it. When the rail pad moves, the scraper moves with it. The spring can make the scraper always contact with the surface of the photovoltaic panel, which is conducive to scraping off the water on the surface of the photovoltaic panel and avoiding the impact of accumulated water on the use of the photovoltaic panel.

[0006] Specifically, connecting rods and connecting sleeves are integrally formed on both sides of the spliced ​​buoy, and through holes are provided on the two connecting sleeves and the connecting rods.

[0007] By adopting the above technical solution, the arrangement of the connecting sleeve, the connecting rod and the through hole is conducive to the splicing of two adjacent spliced ​​buoys.

[0008] Specifically, the wall cleaning mechanism includes side arms and brushes. Side arms are fixed on both sides of the slide seat, and brushes are rotatably connected to the two side arms.

[0009] By adopting the above technical solution, when the slide moves, the side arm is driven to move, and the brush moves along with it, thereby cleaning the debris between the photovoltaic panels and preventing the debris from clogging the gap between the two photovoltaic panels and causing water accumulation.

[0010] Specifically, the top ends of the two drain plates are both configured as inclined surfaces.

[0011] Specifically, the support frame is connected to the two first support rods through bolts, and the two second support rods are both connected to the support frame through bolts.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to prevent rainwater from accumulating, as an embodiment of the present invention, Figures 1 to 5 As shown, the utility model describes an anti-water accumulation device for photovoltaic panels on water, comprising a spliced ​​float 1, a support rod 2, a support frame 3, a photovoltaic panel 4, a water removal mechanism 6 and a wall cleaning mechanism 7. The top of the spliced ​​float 1 is fixed with two first support rods 2 and two second support rods 20 by bolts. The two first support rods 2 and the second support rods 20 are both located between the support frame 3 and the spliced ​​float 1. The tops of the two first support rods 2 and the second support rods 20 are both connected to the support frame 3. Two water discharge plates 5 and four photovoltaic panels 4 arranged in a rectangular array are provided on the support frame 3. The two water discharge plates 5 are welded to the support frame 3. A water removal mechanism 6 is provided on the support frame 3, and a wall cleaning mechanism 7 is provided on the water removal mechanism 6. The water removal mechanism 6 includes a truss 61, a motor 62, a screw 63, a slide 64, a rail pad 65 and a scraper 66. Two trusses 61 are welded and fixed on the support frame 3. The motor 62 is fixed to the uppermost truss 61 by bolts. The output shaft of the motor 62 is connected to the screw 63 through a coupling. The end of the screw 63 away from the motor 62 is rotatably connected to the lowermost truss 61. The slide 64 is located between the two trusses 61. The slide 64 is provided with a screw hole adapted to the screw 63. The top of the slide 64 is welded and fixed with a rail pad 65. Scrapers 66 are provided on both sides of the slide 64. Multiple springs are welded and fixed to the top of the two scrapers 66. The tops of the multiple springs are welded and connected to the rail pad 65.

[0024] When in use, the setting of the drain plate 5 is conducive to the flow of accumulated water. The output shaft of the motor 62 drives the screw 63 to rotate, and the slide 64 moves. When the slide 64 moves, the rail pad 65 moves accordingly. When the rail pad 65 moves, the scraper 66 moves accordingly. The spring can make the scraper 66 always in contact with the surface of the photovoltaic panel 4, which is conducive to scraping off the water on the surface of the photovoltaic panel 4 and avoiding the influence of accumulated water on the use of the photovoltaic panel.

[0025] In order to facilitate the splicing of two adjacent splicing buoys 1, for example, Figure 1As shown, connecting rods 10 and connecting sleeves 11 are integrally formed on both sides of the spliced ​​buoy 1, and through holes are formed on the two connecting sleeves 11 and the connecting rods 10.

[0026] In order to prevent debris from clogging the gap between two adjacent photovoltaic panels 4, for example, Figure 5 As shown, the wall cleaning mechanism 7 includes side arms 71 and brushes 72 . The side arms 71 are fixed to both sides of the slide 64 by bolts, and the brushes 72 are rotatably connected to the two side arms 71 .

[0027] When in use, the slide 64 moves, driving the side arm 71 to move, and the brush 72 moves accordingly, thereby cleaning the debris between the two photovoltaic panels 4 to prevent the debris from clogging the gap between the two photovoltaic panels 4 and causing water accumulation.

[0028] In order to facilitate the discharge of water, for example, Figure 3 As shown, the top ends of the two drain plates 5 are both configured as inclined surfaces.

[0029] The support frame 3 is connected to the two first support rods 2 by bolts, and the two second support rods 20 are both connected to the support frame 3 by bolts.

[0030] When the utility model is in use, the arrangement of the connecting rod 10, the connecting sleeve 11 and the through holes on the connecting rod 10 and the connecting sleeve 11 facilitates the splicing of two adjacent splicing buoys 1, and the arrangement of the water discharge plate 5 facilitates the flow of accumulated water.

[0031] The output shaft of the motor 62 drives the screw 63 to rotate, and the slide 64 moves. When the slide 64 moves, the rail pad 65 moves accordingly. When the rail pad 65 moves, the scraper 66 moves accordingly. The spring can ensure that the scraper 66 is always in contact with the surface of the photovoltaic panel 4, which is conducive to scraping off the water on the surface of the photovoltaic panel 4 and preventing water accumulation from affecting the use of the photovoltaic panel.

[0032] When the slide 64 moves, the side arm 71 is driven to move, and the brush 72 moves accordingly, thereby cleaning the debris between the two photovoltaic panels 4 to prevent the debris from clogging the gap between the two photovoltaic panels 4 and causing water accumulation.
