The invention has a small floor area, is convenient for storage, can rotate with the rising and setting of the sun, enables the absorption of light energy to be unrestricted, and has good heat dissipation effect and high power generation efficiency.

[0028] Refer to Figures 1 to 5As shown, the telescopic base 5 includes the two second double-ended electric telescopic rods 51 arranged in parallel. Two longitudinal connecting rods 52 are respectively fixedly connected to the two extending ends of the second double-ended electric telescopic rod 51. A light tracking device is fixedly connected to the center of any one of the longitudinal connecting rods 52. Universal wheels 10 are fixedly connected to the bottoms of the two longitudinal connecting rods 52. In this embodiment, the second double-ended electric telescopic rod 51 unfolds or retracts following the folding telescopic frame 4. While connecting the two longitudinal connecting rods 52, the second double-ended electric telescopic rod 51 realizes the telescopic function. The setting of the universal wheels 10 provides convenience for the mobile photovoltaic power generation device.

[0029] Refer to Figures 1 to 5 As shown, the light tracking device includes two vertically arranged electric telescopic rods 7 arranged opposite to each other, a PLC controller, and a timer.

In this embodiment, the PLC controller controls one of the vertically arranged electric telescopic rods 7 to rise a certain height according to the unit time of the timer, and at the same time the other vertically arranged electric telescopic rod 7 descends a corresponding height, thereby realizing the rotation of the folding telescopic frame 4 following the sun, and further making the solar panel 1 always face the sun.

[0030] Refer to Figures 1 to 5 As shown, the folding telescopic frame 4 includes two Y-direction connecting rods 41 arranged opposite to each other. Horizontally arranged X-direction electric telescopic rods 42 are fixedly connected to one side of both ends of the Y-direction connecting rods 41.

The two X-direction electric telescopic rods 42 are rotatably connected to the two horizontal sides of the insulating frame 3. The Y-direction connecting rod 41 is movably connected to one vertical side of the insulating frame 3 through the connecting member 6. The bottom of the Y-direction connecting rod 41 is fixedly connected to the light tracking device. In this embodiment, when it is unfolded, the X-direction electric telescopic rod 42 unfolds, and the insulating frame 3 is turned from vertical to horizontal, making the solar panel 1 face upward. The insulating frame 3 is connected and buckled with the folding telescopic frame 4 through the connecting member 6. When it is retracted, the insulating frame 3 is disconnected from the folding telescopic frame 4, the insulating frame 3 is turned from horizontal to vertical, and the X-direction electric telescopic rod 42 retracts, thereby realizing contraction and folding, greatly saving the storage space.

[0031] Refer to Figures 1 to 5As shown in the figure, the X-direction electric telescopic rod 42 includes a first double-ended electric telescopic rod 421.

The extending ends of the two transverse electric telescopic rods 423 are fixedly connected to the Y-direction connecting rod 41. One of the connecting seats 422 is rotatably connected to any one of the transverse sides of the insulating frame 3. In this embodiment, when the X-direction electric telescopic rod 42 extends, the two transverse electric telescopic rods 423 and both ends of the first double-ended electric telescopic rod 421 extend simultaneously, pushing the two Y-direction connecting rods 41 to both sides; when the X-direction electric telescopic rod 42 retracts, the transverse electric telescopic rods 423 and both ends of the first double-ended electric telescopic rod 421 retract simultaneously, pulling the two Y-direction connecting rods 41 closer to the middle.

[0032] Refer to Figures 1 to 5 As shown in the figure, the middle parts of the two transverse sides of the insulating frame 3 are fixedly provided with turning shafts 31 opposite to each other. The insulating frame 3 is rotatably connected to the folding telescopic frame 4 through the turning shafts 31. One vertical side of the insulating frame 3 is movably inserted into the connecting end of the connecting member 6. The limiting end of the connecting member 6 is rotatably connected to the folding telescopic frame 4. The insulating frame 3 is fixedly connected to the heat dissipation device 2. In this embodiment, the insulating frame 3 realizes flipping through the turning shafts 31, thereby realizing the flipping of the solar panel 1. When the insulating frame 3 is in a horizontal state, it is connected to the Y-direction connecting rod 42 through the connecting member 6. When the insulating frame 3 is in a vertical state, the insulating frame 3 is disconnected from the Y-direction connecting rod 42.

The ends of the two pressing rods 63 facing the insulating frame 3 are provided with connecting protrusions 65 matching the connecting grooves 62. The other ends of the two pressing rods 63 are elastically connected by a first spring. In this embodiment, when the insulating frame 3 needs to be connected to the Y-direction connecting rod 41, the connecting column 61 slides out, and the connecting groove 62 is buckled with the connecting protrusion 65, and the connection between the insulating frame 3 and the Y-direction connecting rod 41 is maintained under the action of the first spring 64 and the pressing rod 63; when the insulating frame 3 needs to return to the vertical state, the two pressing rods 63 are simultaneously squeezed towards the middle, so that the connecting protrusion 65 is separated from the connecting groove 62, and the insulating frame 3 is disconnected from the Y-direction connecting rod 41.

[0034] Refer to Figures 1 to 5 As shown, a push block 8 is fixedly provided on the upper surface of the movable insertion end of the connecting column 61 and the insulating frame 3. In this embodiment, the provision of the push block 8 facilitates the sliding out of the connecting column 61.

A condensing pipe 25 is provided inside the heat dissipation fin 24. In this embodiment, the heat generated when the solar panel 1 works is efficiently conducted to the metal plate 22 through the heat conduction plate 21 belonging to it. The metal plate 22 then conducts the heat to the heat dissipation fin 24. The heat is quickly dissipated into the air through the heat dissipation fin 24 and carried away by the air. The condensing pipe 25 effectively improves the heat dissipation efficiency of the heat dissipation fin 24, thereby greatly improving the power generation efficiency of the solar panel 1.
