[0025] Example 2, as Figure 1-6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the adjustment mechanism 7 includes a bottom column 71, the bottom end of the bottom column 71 is rotatably connected to the second rotating rod 77, the bottom column 71 is rotatably connected to the top surface of the base 1 through the second rotating rod 77, the inner cavity of the bottom column 71 is movably sleeved with an adjustment plate 75, the top of the adjustment plate 75 is rotatably connected to the first rotating rod 76, the top of the adjustment plate 75 is rotatably connected to the bottom surface of the rotating plate 4 through the first rotating rod 76, the bottom surface of the inner cavity of the bottom column 71 is fixedly connected to the second forward and reverse motor 72, the output shaft of the second forward and reverse motor 72 is fixedly connected to the second threaded rod 73, the second threaded rod 73 is connected to the internal thread of the adjustment plate 75, and both sides of the bottom surface of the adjustment plate 75 are movably sleeved with limit plates 74, and the bottom end of the limit plate 74 is fixedly connected to the bottom surface of the inner cavity of the bottom column 71.

[0026] This bracket drives the second threaded rod 73 to rotate through the rotation of the second forward and reverse motor 72, and the second threaded rod 73 drives the adjustment plate 75 to move up and down in the base column 71. The setting of the limit plate 74 allows the adjustment plate 75 to move up and down smoothly.

[0027] Example 3, as Figure 1-6As shown, based on Example 2, the present invention provides a technical solution: preferably, a power supply 68, a central control machine 69 and a Bluetooth module 610 are provided in the power space, and the power supply 68, the central control machine 69 and the Bluetooth module 610 are all fixedly connected to the inner cavity of the electric control box 61, the power supply 68 is electrically connected to the first forward and reverse motor 41, the second forward and reverse motor 72, the heating wire 67, and the motor 64, the central control machine 69 is connected to the Bluetooth module 610, the central control machine 69 is electrically connected to the first forward and reverse motor 41, the second forward and reverse motor 72, the heating wire 67, and the motor 64, and the power supply 68 is electrically connected to the photovoltaic panel body 5.

[0028] This bracket is connected to the photovoltaic panel body 5 through the power supply 68, which facilitates the storage of part of the electricity generated by the photovoltaic panel body 5 in the power supply 68, and uses the power supply 68 to provide power to the first forward and reverse motor 41, the second forward and reverse motor 72, the heating wire 67, and the motor 64 in the overall device.

[0029] The working principle of the snow-proof photovoltaic bracket of the present invention is as follows: like Figure 1-6As shown, when the bracket is used, according to the required tilt angle, the rotation of the second forward and reverse motor 72 drives the threaded rod 2 73 to rotate, and the threaded rod 2 73 drives the adjustment plate 75 to move up and down in the bottom column 71.

When the rolling drum 46 moves, the engagement of the circular gear 47 and the serrated bar 48 drives the rolling drum 46 to rotate. At the same time, the motor 64 drives the blowing fan 65 to rotate. When the blowing fan 65 rotates, the outside air enters the electric control box 61 through the air inlet 66, and the sponge plate 63 removes moisture from the air. The heating wire 67 heats the air into hot air, and the hot air is blown into the interior of the rolling drum 46 through the blowing pipe 611. The rotating rolling drum 46 is used to blow the hot air evenly out from the ventilation slot 462, and the hot air is used to quickly melt the snow on the surface of the photovoltaic panel body 5.
