[0002] Solar photovoltaic power stations are renewable energy power plants that use solar panels to directly convert sunlight into electrical energy. This form of power generation is renewable and environmentally friendly because it does not emit greenhouse gases or consume any fuel. The main components of solar power generation include solar photovoltaic panels, inverters, support systems, and electrical connection equipment. Photovoltaic panels are composed of multiple photovoltaic cells, which are usually made of semiconductor materials such as silicon. When exposed to sunlight, electrons flow, thereby generating electricity.

[0003] To ensure the power generation efficiency of photovoltaic panels, the surface of photovoltaic panels needs to be cleaned regularly to avoid reducing the power generation efficiency due to dust coverage. Dust or stains will cause abnormal temperature in that part of the photovoltaic panel, which will shorten the service life of the photovoltaic panel. Therefore, a cleaning robot is needed to clean the photovoltaic panels.

The nozzles 132 are all connected to the bent pipe 131 and adapted to the soft brush 122.

[0029] During the horizontal movement of the bending frame 8, the external water supply is transported to the nozzle 132 through the bending pipe 131, and then the water is sprayed to the contact point between the soft brush 122 and the photovoltaic panel 2. At the same time, the second motor 123 drives the soft brush 122 to rotate through the main shaft 121, so that the dust and stains on the top of the photovoltaic panel 2 can be cleaned; Reference Figure 6 and Figure 7 The winding assembly 16 includes a mounting seat 161, an electric slip ring 162, a water pipe rotary joint 163, a mounting shaft 164, a winding roller 165, a conveying pipe 166, a cable 167, a housing 168 and a coil spring 169.

The rear sides of the electric slip ring 162 and the water pipe rotary joint 163 are fixedly connected with a mounting shaft 164 which is rotatably connected to the mounting frame 14 and extends to the rear side of the mounting frame 14. The outer sides of the mounting shaft 164 are fixedly connected with a mounting shaft located at The winding roller 165 in the mounting frame 14 has a conveying tube 166 and a cable 167 wound around its outer side, the conveying tube 166 passes through an installation shaft 164 to communicate with the water pipe rotary joint 163, the cable 167 passes through another installation shaft 164 to be electrically connected to the electric slip ring 162, the other end of the conveying tube 166 is connected to the bending pipeline 131, the cable 167 is electrically connected to the first motor 101, the second motor 123 and the electric control box 15, the rear side of the mounting frame 14 is fixedly connected to a shell 168 located on the outer side of the installation shaft 164, and the outer side of one end of the installation shaft 164 is fixedly connected to a coil spring 169 fixedly connected to the inner wall of the shell 168.

When the bending frame 8 is reset, the coil spring 169 restores the elastic deformation, thereby driving the winding roller 165 to rotate through the installation shaft 164, so that the conveying tube 166 and the cable 167 can be wound at any time to prevent the conveying tube 166 and the cable 167 from being stuck in the gap or hanging.

[0031] The working principle of this embodiment is: Step 1: The electric control box 15 periodically drives the first motor 101 to drive the third gear 102 to rotate. Since the third gear 102 is meshed with the second gear 903, the first gear 902 is driven to rotate synchronously through the transmission shaft 901. Since the first gear 902 is meshed with the rack 5, the second slide 7 is driven to slide on the outer side of the second guide rail 4, and the bending frame 8 and the first slide 6 are driven to move horizontally.

At the same time, the second motor 123 drives the soft brush 122 to rotate through the main shaft 121, so that the dust and stains on the top of the photovoltaic panel 2 can be brushed clean. When the bending frame 8 is reset, the coil spring 169 restores its elastic deformation, thereby driving the winding roller 165 to rotate through the installation shaft 164, so that the conveying tube 166 and the cable 167 can be wound at any time to prevent the conveying tube 166 and the cable 167 from being stuck in the gap or hanging.

[0032] Example 2 A method for cleaning a photovoltaic panel comprises the following steps: S1: The electric control box 15 regularly drives the first motor 101 to rotate forward, so that the first motor 101 drives the third gear 102 to rotate, and the third gear 102 drives the first gear 902 to rotate synchronously through the transmission shaft 901, and the first gear 902 moves horizontally along the rack 5, thereby driving the second slide 7 to slide along the second guide rail 4, and the second slide 7 drives the bending frame 8 and the first slide 6 to move horizontally; S2: During the horizontal movement of the bending frame 8, the conveying pipe 166 and the cable 167 are pulled to drive the winding roller 165 to rotate outside the mounting shaft 164, and at the same time, the coil spring 169 is elastically deformed, so that the conveying pipe 166 and the cable 167 are in a taut state in the air, and the conveying pipe 166 conveys the external water supply to the bending pipeline 131, and the cable 167 supplies power to the first motor 101 and the second motor 123; During the horizontal movement of the bending frame 8, the external water supply is transported to the nozzle 132 through the bending pipe 131, and then the water is sprayed to the contact point between the soft brush 122 and the photovoltaic panel 2. At the same time, the second motor 123 drives the soft brush 122 to rotate through the main shaft 121 to brush the dust and stains on the surface of the photovoltaic panel 2. After the brushing is completed, the electrical control box 15 drives the first motor 101 to reverse, so that the bending frame 8 is reset. After the bending frame 8 is reset, the coil spring 169 restores its elastic deformation, thereby driving the winding roller 165 to rotate through the installation shaft 164, so that the conveying pipe 166 and the cable 167 can be wound at any time to prevent the conveying pipe 166 and the cable 167 from being stuck in the gap or hanging.
