[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-5 A photovoltaic module support device includes: a support box 1, and further includes: a frame 101 disposed on the upper side of the support box 1; a rotating shaft 112 symmetrically fixedly connected to both sides of the frame 101, and the rotating shaft 112 is rotatably disposed within the support box 1; a photovoltaic panel 102 disposed on the frame 101; a lifting component for lifting one end of the frame 101; a controller 110 disposed within the support box 1; and a ventilation slot 103 disposed between the photovoltaic panel 102 and the frame 101.

[0025] The lifting assembly includes an electric telescopic rod 2 disposed between the support box 1 and the photovoltaic panel 102. One end of the electric telescopic rod 2 is rotatably connected to the photovoltaic panel 102, and the other end of the electric telescopic rod 2 is rotatably connected to the support box 1.

[0026] During daytime use, the electric telescopic rod 2 is extended by the controller 110, which lifts one end of the frame 101, giving the photovoltaic panel 102 a certain tilt angle, thus enabling the conversion of solar energy. At night, when the photovoltaic panel 102 is not in use, the electric telescopic rod 2 is reset by the controller 110, at which time the frame 101 is reset and retracted into the support box 1, thereby effectively reducing the time that the photovoltaic panel 102 is blown by the wind, and at the same time effectively preventing the wind from blowing on the back of the photovoltaic panel 102 for a long time, affecting its stability.

[0027] The extension and retraction of the electric telescopic pole 2 is controlled by the controller 110 at a set time.

[0028] Example 2: Refer to Figures 1-5 A photovoltaic module support device is basically the same as in Embodiment 1. Further, a slide rail 104 is symmetrically fixedly connected to the frame 101, a slide groove 105 is provided in the slide rail 104, a square rod 106 is slidably arranged between the two slide grooves 105, a shielding plate 108 is fixedly connected to the square rod 106, and a drive component for driving the square rod 106 to slide in the slide groove 105 is provided in the support box 1.

[0029] The drive assembly includes a first pull rope 109 symmetrically and fixedly connected between the shielding plate 108 and the support box 1. A first guide rod 201, a second guide rod 202 and a third guide rod 204 are fixedly connected inside the support box 1. A second pull rope 203 is fixedly connected between the frame 101 and the first pull rope 109. The first guide rod 201, the second guide rod 202 and the third guide rod 204 are all guided by the second pull rope 203. An elastic rope 113 is fixedly connected between the square rod 106 and the frame 101. The rotating shaft 112 is used to guide the elastic rope 113.

[0030] Drainage grooves 111 are symmetrically provided at the lower end of the support box 1.

[0031] A scraper 107 matching the photovoltaic panel 102 is fixedly connected to the lower side of the square rod 106.

[0032] When the electric telescopic rod 2 extends, one end of the frame 101 rises. At this time, the first pull rope 109 pulls the shielding plate 108, causing the square rod 106 to slide in the groove 105. The second pull rope 203 pulls the first pull rope 109 to move, thereby gradually pulling up the shielding plate 108 so that the shielding plate 108 no longer blocks the photovoltaic panel 102. When the electric telescopic rod 2 returns to its original position, the square rod 106 is pulled back to its original position by the elastic rope 113, thus completing the shading of the photovoltaic panel 102. This effectively reduces the amount of dust accumulation on the surface of the photovoltaic panel 102 at night. When the square rod 106 slides in the groove 105, it drives the scraper 107 to clean the surface of the photovoltaic panel 102, thereby effectively preventing the accumulation of dust on the surface of the photovoltaic panel 102 from affecting its power generation efficiency.

[0033] When the frame 101 is tilted, the shielding plate 108 shields the back of the photovoltaic panel 102, thereby effectively preventing wind from blowing directly onto the back of the photovoltaic panel 102 and affecting its stability.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
