Description

Technical Field

[0002] As we all know, photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert light energy into electrical energy. It primarily consists of three main components: solar panels (modules), controllers, and inverters. These components are primarily electronic components. Solar cells are connected in series and then encapsulated and protected to form large-area solar modules. Combined with components such as power controllers, these form photovoltaic power generation devices. After prolonged use, debris and dust accumulate on the solar panels, potentially affecting their effectiveness. Therefore, photovoltaic cleaning robots are often used to clean these panels.

[0003] Traditional photovoltaic cleaning robots are unable to adjust the position of the scraper, and thus cannot adapt well to the size of the photovoltaic panels, causing inconvenience to actual cleaning. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a terrain-adaptive photovoltaic cleaning robot, comprising a frame 1, a bidirectional screw 7 is rotatably inserted between the frame 1, and symmetrically distributed nut blocks 10 are threadedly sleeved on the bidirectional screw 7. A guide rod 9 is fixedly connected between the inner walls of the frame 1, and the guide rod 9 movably penetrates the nut block 10. A telescopic component is fixedly installed at the bottom end of the nut block 10, and a scraper 13 is fixedly connected to the lower end of the telescopic component. A cleaning sponge is fixedly installed at the bottom of the scraper 13. By setting the telescopic component, the cleaning sponge can be fitted to the surface of the photovoltaic panel.

[0024] By driving the bidirectional screw 7 to rotate, the bidirectional screw 7 drives the two nut blocks 10 to move linearly, thereby adjusting the position of the scraper 13 and the cleaning sponge at the bottom thereof.

[0025] A positioning plate 4 is fixedly connected to the middle of the inner wall of the frame 1 , a base 2 is provided below the positioning plate 4 , a first motor 3 is fixedly installed on the top of the base 2 , and an output end of the first motor 3 is fixedly connected to the positioning plate 4 .

[0026] The first motor 3 is started to drive the positioning plate 4 and the frame 1 to rotate, so that the cleaning sponge at the bottom of the scraper 13 cleans the surface of the photovoltaic panel.

[0027] A walking mechanism 5 is fixedly mounted on the bottom of the base 2 to enable the entire device to move. Wheeled walking is the most common design in the prior art, and the robot moves on the surface of the photovoltaic panel using wheels. Wheeled walking is simple and reliable and is suitable for flat photovoltaic panel surfaces.

[0028] Specifically, the telescopic assembly includes a telescopic rod 12 and a spring 11 sleeved on the telescopic rod 12 . The upper and lower ends of the spring 11 and the telescopic rod 12 are fixedly connected to the nut block 10 and the scraper 13 respectively.

[0029] Under the elastic action of the spring 11, the scraper 13 is pushed down, so that the cleaning sponge at the bottom of the scraper 13 contacts the surface of the photovoltaic panel, ensuring that the cleaning sponge can always fit the photovoltaic panel to achieve the purpose of terrain adaptation. The telescopic rod 12 realizes the linear guidance of the scraper 13 to ensure that the scraper 13 moves in a straight line direction.

[0030] In order to drive the bidirectional screw 7, a driven bevel gear 8 is fixedly connected to the bidirectional screw 7, and a second motor 14 is fixedly installed on the outer wall of the frame 1. The output end of the second motor 14 passes through the interior of the frame 1 and is fixedly connected to the driving bevel gear 6. The driving bevel gear 6 is meshed with the driven bevel gear 8.

[0031] Start the second motor 14 to drive the active bevel gear 6 to rotate, the active bevel gear 6 drives the driven bevel gear 8 to rotate, the driven bevel gear 8 drives the bidirectional screw 7 to rotate, and the bidirectional screw 7 drives the nut block 10 to move linearly, adjusting the position of the scraper 13 and the cleaning sponge at its bottom to be more suitable for the size of the photovoltaic panel and help clean the photovoltaic panel.

[0032] The guide rod 9 is a round rod structure, and the surface of the guide rod 9 is polished, so that the displacement of the nut block 10 is smoother.
