A cleaning mechanism 6 for cleaning the solar panel 1 is installed between the tops of the two frames 5. A recycling mechanism 7 is fixedly installed between the two frames 5. Installing the solar panel 1 on the charging station can make reasonable use of the space of the charging station.

[0025] Embodiment 3:

[0026] As Figure 2 and Figure 3 shown in the figure, the cleaning mechanism 6 includes a U-shaped frame 61 fixedly installed on the tops of the two frames 5. Long grooves 62 are opened on both sides of the upper surface of the U-shaped frame 61. Two motors 63 are symmetrically and fixedly connected to one side of the outer surface of the U-shaped frame 61. Output shafts of the two motors 63 are fixedly connected with bidirectional lead screws 64 rotatably connected to the inside of the long grooves 62. Two sliders 65 slidably connected to the inner walls of the long grooves 62 are symmetrically and threadedly connected to the outer surfaces of the two bidirectional lead screws 64. A horizontal pipe 66 is fixedly connected between the two sliders 65 on one side. A plurality of nozzles 67 are sequentially and obliquely fixedly connected to the lower surface of the horizontal pipe 66. The rotation of the motor 63 drives the bidirectional lead screw 64 to rotate, thereby driving the slider 65 and the horizontal pipe 66 to move, and further driving the nozzles 67 to uniformly spray water on the surface of the solar panel 1 for cleaning, improving the cleaning effect, and thus solving the problem that the cleaning pipe structure of the existing device is fixed and cannot move, thereby reducing the cleaning effect on the photovoltaic panel.

[0027] The cleaning mechanism 6 further includes a water storage tank 68 fixedly installed on the upper surface of the base 2. One side of the outer surface of the water storage tank 68 is fixedly communicated with a water pump 69. The output end of the water pump 69 is fixedly connected to a connecting pipe 610. One end of the connecting pipe 610 is fixedly connected to a tee 611. Both ends of the tee 611 are fixedly connected to a hose 612. One end of the hose 612 is fixedly communicated with the inside of the adjacent horizontal pipe 66. When the water pump 69 operates, the clear water in the water storage tank 68 can be pumped out and conveyed into the horizontal pipe 66, and then sprayed out through the nozzle 67.

[0028] Embodiment 4:

[0029] As Figure 2 and Figure 4 As shown, the recycling mechanism 7 includes a centralized frame 71 fixedly connected to the two frames 5. The top and one side of the centralized frame 71 are both open. The top of the centralized frame 71 is flush with the top of the frame 5. One side of the outer surface of the centralized frame 71 is fixedly connected to a collection box 72. A notch 73 communicating with the centralized frame 71 is opened on one side of the outer surface of the collection box 72. A filter screen 74 is fixedly embedded inside the collection box 72. A water return pipe 75 is fixedly communicated between the bottom of the collection box 72 and the top end of the water storage tank 68. The inner bottom of the centralized frame 71 is inclined. The cleaned water and sundries enter the centralized frame 71, then fall into the collection box 72 through the notch 73 and are filtered by the filter screen 74. The filtered water enters the water storage tank 68 through the water return pipe 75 for reuse.

[0030] An opening 76 is opened on one side of the outer surface of the collection box 72. A sealing plate 77 is detachably embedded inside the opening 76. The collection box 72 can centrally collect the filtered sundries to avoid environmental pollution. By opening the sealing plate 77, the sundries can be taken out through the opening 76, thus solving the problem that the existing device cannot collect the filtered sundries, resulting in environmental pollution.

[0031] Working principle: Photovoltaic power generation is introduced. After the solar panels 1 generate electricity, they can charge the energy storage system and then supply power to the charging station, improving the energy utilization efficiency and reducing the operating cost of the charging station.

[0032] The operation of the water pump 69 can pump out the clear water in the water storage tank 68 and transport it to the horizontal pipe 66, and then spray it out through the nozzle 67. The rotation of the motor 63 drives the rotation of the bidirectional lead screw 64, thereby driving the slider 65 and the horizontal pipe 66 to move, and further driving the nozzle 67 to evenly spray and clean the surface of the solar panel 1, improving the cleaning effect. Thus, it solves the problem that the cleaning pipe structure of the existing device is fixed and cannot move, thereby reducing the cleaning effect on the photovoltaic panel. The cleaned water and debris enter the centralized frame 71, and then fall into the collection frame 72 through the notch 73 and are filtered by the filter screen 74. The filtered water enters the water storage tank 68 through the return pipe 75 for reuse. The collection frame 72 can centrally collect the filtered debris to avoid environmental pollution. Opening the sealing plate 77 allows the debris to be taken out through the opening 76, thus solving the problem that the existing device cannot collect the filtered debris, thereby polluting the environment.
