Referring to fig. 10, in order to accelerate the sliding of snow on the ceiling 40, the first adjusting leg 20 and the second adjusting leg 30 are designed for this purpose, and the ceiling 40 is driven to move up and down by the up-and-down movement of the first adjusting leg 20 and the second adjusting leg 30, so that the sliding of snow on the ceiling 40 is accelerated.

The first adjusting leg 20 and the second adjusting leg 30 both comprise a base 201, an expansion link 203, a supporting block 205, a transmission motor 206, a transmission gear 207, a driven gear 208, a rotating rod 209, a sleeve 204 and a connecting seat 202;

the bases 201 are fixedly connected to the left side and the right side of the upper end face of the power distribution cabinet 10 respectively;

the telescopic rod 203 is fixedly connected to the upper end of the base 201;

the supporting block 205 is fixedly connected to the upper end of the base 201, and the supporting block 205 is located on the right side of the telescopic rod 203 and used for installing and supporting the transmission motor 206;

a transmission motor 206 fixedly connected to the upper end of the supporting block 205 for providing power for the rotation of the transmission gear 207;

a transmission gear 207 rotatably connected to the right end of the transmission motor 206;

a driven gear 208 rotatably connected to the upper end of the base 2014, wherein the driven gear 208 is positioned at the right side of the transmission gear 207, and the driven gear 208 and the transmission gear 207 are meshed for rotation;

a rotating rod 209 rotatably connected to the upper end of the driven gear 208;

the sleeve 204 is sleeved outside the rotating rod 209 in a sliding manner;

and the connecting seat 202 is transversely and fixedly connected to the upper ends of the telescopic rod 203 and the sleeve 204, and the upper end of the connecting seat 202 is fixedly connected to the inner wall of the bottom end of the left shielding shed 41 and the inner wall of the bottom end of the right shielding shed 42 respectively.

The rotating rod 209 also adopts a screw rod, internal threads are arranged in the sleeve 204, and the sleeve 204 and the rotating rod 209 are rotatably connected through threads, so that the sleeve 204 can slide up and down;

that is, the driving motor 206 is operated to drive the rotating rod 209 to rotate clockwise, so as to drive the sleeve 204 to slide upwards, and the telescopic rod 203 extends upwards, so that the ceiling 40 is jacked upwards through the connecting base 202. The rotating rod 209 rotates counterclockwise, so as to drive the sleeve 204 to slide downwards, and the telescopic rod 203 stretches downwards, thereby realizing the downward movement of the ceiling 40.

During actual operation of the embodiment of the application, the transmission motor 206 works to drive the rotating rod 209 to rotate clockwise or anticlockwise, so that the sliding sleeve 204 slides up and down, and the telescopic rod 203 is driven to extend or retract, thereby realizing up and down movement of the ceiling 40.

The technical scheme in the embodiment of the application at least has the following technical effects or advantages: the sliding of snow falling from the ceiling is accelerated by the up-and-down movement of the upper ceiling and the lower ceiling of the first adjusting leg and the second adjusting leg.

Jacking motor 431, transmission motor 206 in this application just reverse the accessible PLC or increase photoelectric switch in the circuit and realize that jacking motor 431, transmission motor 206's two-way automatic control can.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
