[0026] like Figures 1 to 5 As shown, it includes a support frame 4, the top array of the support frame 4 is provided with a mounting frame 2, a photovoltaic component 1 for photoelectric conversion is provided inside the mounting frame 2, and the photovoltaic component 1 is movably connected to the mounting frame 2, a cleaning component 3 for cleaning dust on the surface of the photovoltaic component 1 is provided inside the photovoltaic component 1, and the cleaning component 3 is movably connected to the photovoltaic component 1.

[0027] Specifically, the photovoltaic component 1 can not only be moved and adjusted in the horizontal direction on the top surface of the support frame 4, but also can be flipped and adjusted in the vertical plane, so that the photovoltaic component 1 can be adjusted according to the lighting requirements of different plants, and when the plants need light, the device can maximize the light transmission operation, and the cleaning component 3 can efficiently remove dust on the surface of the photovoltaic component 1. These designs improve the photoelectric conversion efficiency of the device and the utilization rate of sunlight.

[0028] The photovoltaic assembly 1 includes an upper frame 101 and a lower frame 106, and the upper frame 101 and the lower frame 106 are axially symmetrical structures with respect to the mounting frame 2. The surfaces of the upper frame 101 and the lower frame 106 are provided with connecting blocks 103. The upper frame 101 and the lower frame 106 are provided with photovoltaic panels 102 respectively, and the photovoltaic panels 102 are movably connected to the upper frame 101 and the lower frame 106 respectively. The upper frame 101 and the lower frame 106 are provided with flip motors 105 respectively, and the output ends of the flip motors 105 are fixedly connected to the sides of the photovoltaic panels 102 respectively. The inner sides of the upper frame 101 and the lower frame 106 are provided with movable grooves 104 respectively. The inner side of the mounting frame 2 is provided with an adjustment groove 9, and the adjustment groove 9 is slidably connected to the upper frame 101 and the lower frame 106 respectively, and the adjustment groove 9 is movably connected to the connecting block 103. The adjustment groove 9 is provided with an adjustment screw 8, and the adjustment screw 8 is threadedly connected to the connecting block 103 respectively, and an adjustment motor 6 is fixed to one end of the adjustment screw 8.

[0029] Specifically, in the mounting frame 2, the adjusting motor 6 drives the adjusting screw 8 in the adjusting slot 9 to rotate, and then the adjusting screw 8 drives the connecting block 103 in the photovoltaic component 1 to move in the adjusting slot 9, so that the upper frame 101 and the lower frame 106 move in the adjusting slot 9. The adjusting screw 8 is a bidirectional screw, which can adjust the overlap between the upper frame 101 and the lower frame 106. When all the plants need light, under the drive of the flipping motor 105, the photovoltaic panel 102 in the upper frame 101 and the lower frame 106 can be flipped and adjusted along the light direction to achieve the adjustment of the light area.

[0030] The cleaning component 3 includes a water tank 306, a sponge pad 304 is provided on the bottom surface of the water tank 306, a movable column 302 is arranged in an array inside the water tank 306, and the bottom end of the movable column 302 passes through the bottom surface of the water tank 306, a limiting ring 303 is provided on the surface of the movable column 302, and a sealing ring 305 is provided on the bottom surface of the limiting ring 303, and the sealing ring 305 is made of rubber thermoplastic, a return spring 301 is provided on the surface of the movable column 302, and the two ends of the return spring 301 are respectively fixedly connected to the limiting ring 303 and the water tank 306, a movable screw rod 7 is provided in the movable groove 104, and the movable screw rod 7 is threadedly connected to the water tank 306, and a movable motor 5 is fixed to one end of the movable screw rod 7.

[0031] Specifically, in the cleaning component 3, the moving motor 5 drives the moving screw 7 to rotate, and then the moving screw 7 drives the water tank 306 to move in the moving groove 104. When the water tank 306 contacts the photovoltaic panel 102, the photovoltaic panel 102 will push the movable column 302 into the water tank 306, and then the water in the water tank 306 will diffuse into the sponge pad 304 to wipe the photovoltaic panel 102. When the wiping is completed, the water tank 306 returns to its original position. Under the action of the reset spring 301, the movable column 302 will continue to protrude from the bottom of the water tank 306, and the sealing ring 305 on the bottom of the limit ring 303 can prevent the water in the water tank 306 from leaking out.

[0032] In summary: in the installation frame 2, the adjusting motor 6 drives the adjusting screw 8 in the adjusting slot 9 to rotate, and then the adjusting screw 8 drives the connecting block 103 in the photovoltaic component 1 to move in the adjusting slot 9, so that the upper frame 101 and the lower frame 106 move in the adjusting slot 9. The adjusting screw 8 is a bidirectional screw, which can adjust the overlap between the upper frame 101 and the lower frame 106. When all the plants need light, under the drive of the flipping motor 105, the photovoltaic panel 102 in the upper frame 101 and the lower frame 106 can be flipped and adjusted along the light direction to achieve the adjustment of the light area. In the cleaning component 3, the moving motor 5 drives the moving screw 7 to rotate, and then the moving screw 7 drives the water tank 306 to move in the moving slot 104. When the water tank 306 contacts the photovoltaic panel 102, the photovoltaic panel 102 will move the movable column 302. The water in the water tank 306 is pushed into the water tank 306, and then the water in the water tank 306 will diffuse into the sponge pad 304 to wipe the photovoltaic panel 102. When the wiping is completed, the water tank 306 returns to its original position, and the movable column 302 will continue to protrude from the bottom of the water tank 306 under the action of the reset spring 301, and the sealing ring 305 on the bottom of the limit ring 303 can prevent the water in the water tank 306 from leaking out. The photovoltaic component 1 can not only be moved and adjusted in the horizontal direction on the top surface of the support frame 4, but also can be flipped and adjusted in the vertical plane, so that the photovoltaic component 1 can be adjusted according to the lighting requirements of different plants, and when the plants need light, the device can maximize the light transmission operation, and the cleaning component 3 can efficiently remove dust on the surface of the photovoltaic component 1.
