[0024] As a further implementation scheme of the above technical scheme: the front and rear sides of the bottom end of the pushing plate 8 are fixedly connected with a rotating connecting rod 9, the left end of the rotating connecting rod 9 is rotatably connected with a fixing frame 7, the fixing frame 7 is fixedly connected to the front and rear sides of the bottom end of the photovoltaic panel 6, the fixing frame 7 is rotatably connected to the front and rear sides of the left and right ends of the lifting plate 2, and the fixing frame 7 can be connected to the pushing plate 8 by rotating the connecting rod 9.

[0025] As a further implementation scheme of the above technical scheme: the limiting slides 10 are fixedly connected to both sides of the bottom end of the pushing plate 8, the limiting slides 10 are slidably connected to the inner side of the slide rails 12, and the slide rails 12 are opened on the left and right sides of the upper end of the support frame 1. The stability of the pushing plate 8 can be improved by the limiting slides 10 and the slide rails 12.

[0026] As a further implementation scheme of the above technical scheme: the limiting slide 10 has limiting balls 11 slidably connected to its upper and lower ends and its front and rear sides, and the limiting balls 11 are slidably connected to the inner side of the support frame 1. The limiting balls 11 can reduce friction.

[0027] As a further implementation scheme of the above technical scheme: photovoltaic panels 6 are arranged on both sides of the lifting plate 2, and fixing frames 7 are fixedly connected to the front and rear sides of the bottom of the photovoltaic panel 6. The photovoltaic panel 6 is arranged on the inner side of the protective cover 3, and the protective cover 3 can protect the photovoltaic panel 6.

[0030] Working principle:

[0031] In the process of using the utility model, when there is sufficient sunlight, the bidirectional motor 15 can be controlled to drive the screw rod 14 to rotate, the screw rod 14 can move the driving rod 13, and the driving rod 13 can move the protective cover 3 through the L-shaped frame 4.

At the same time, the friction force can be reduced by the limiting ball 11, and the pushing plate 8 can be pushed. The movement of the movable plate 8 will push the fixed frame 7 by rotating the connecting rod 9, and the fixed frame 7 will drive the lifting plate 2 to lift, and cooperate with the limit rod 5 to limit and stabilize the lifting plate 2. When the lifting plate 2 reaches the top of the limit rod 5, the electromagnet 19 is turned off. At this time, the spring 20 will drive the clamping rod 18 to automatically reset, and the protective cover 3 will lock the fixed frame 7, thus completing the lifting and unfolding of the photovoltaic panel 6, and then it can be put into operation. When encountering rainy or windy weather, the two-way motor 15 can be controlled to control the protective cover 3 to move first. At this time, the photovoltaic panel 6 and the lifting plate 2 will push the fixed frame 7 and the pushing plate 8 due to their weight, so that they return to their original positions, and then the two-way motor 15 is controlled to make the protective cover 3 block the photovoltaic panel 6, so as to achieve the effect of protecting the photovoltaic panel 6.
