The working principle of the invention is as follows: the snow-pushing plate 1 is provided with a pressure sensor, when the pressure reaches a value, the pressure sensor can transmit an electric signal to be transmitted to an electric device, a motor in the electric device is electrified to drive a motor shaft 31 to rotate, the motor shaft 31 can drive a coupler 26 to rotate, a pin on the coupler 26 and a retainer ring 18 transmit torque to drive a transmission shaft 32 to rotate, a flat key 36 on a key groove on the transmission shaft 32 transmits torque to drive a cam 17 to rotate, and the cam 17 pushes against a cam baffle 37 when rotating to a remote arc stop around the rotating transmission shaft 32. Carrying the cam lever 16. The cam lever 16 pushes the snow-pushing plate 1 to move upwards to rotate around the hinge pin shaft 6, and snow on the snow-pushing plate is cleared. The snow slides aside along the side snow guards 8. Thereby maintaining the temperature of the interior. And the outdoor condition also can be difficult to avoid having strong wind weather, and below location frame 21 prevents that this kind of condition from taking place when strong wind weather takes place the power supply of the positioning screw 20 of switch board support 14 both sides can be followed the trend and wind the direction skew rotation of blowing. Therefore, the electric cabinet is positioned to ensure that the electric cabinet cannot be laterally turned due to unstable gravity center, and finally, the safety of internal parts and important parts is not damaged.

The anchor bolts 28 at the bottom of the base can also play a role in positioning and preventing side turning. The two cooperate to prevent damage to one of them due to excessive stress. This can lead to miswork and a great deal of economic loss, and influence the daily life of common people. The base 27 is also inclined. Preventing the snow from remaining. The electric cabinet door plate 14 is provided with a sealing layer 25 for preventing snow from sliding down or blowing snow into the power distribution cabinet in windy weather. The supporting plates 33 are arranged at the lower parts of the two side plates, so that the side snow-proof plates 8 can be prevented from being crushed by excessive accumulated snow to cause misoperation. The positioning frame 21 is inclined to a certain degree, so that a certain centripetal force can be generated in windy weather to counteract the blowing force of wind. The lower portion of the anchor bolt 28 is provided with a felt washer 29 to prevent snow from falling therein to damage the internal structure, causing the ground bolt 28 to be damaged by internally tightening and pressing the ground bolt 28, and then causing the anchor bolt to be out of position.

When the temperature generated by the motor in the cabinet body is too high, the piston 11 is pushed by the internal air pressure, the piston 11 opens the air in the cabinet to diffuse out, and finally, the piston 11 is closed again when the internal air pressure and the external air pressure are balanced. The piston 11 reseals the cabinet. This can prevent snow from entering therein and melting into water to cause short circuit of internal circuit and damage of internal structure and important parts. It is also possible to ensure that the internal temperature is too high. The cam structure can rotate stably, the snow-pushing plate 1 can rotate at a constant speed, and the tight connection of the internal structure in low-temperature weather can cause the increase of friction and the generation of heat if the rotation is too fast, so that scaling and explosion finally cause the damage of parts. The top post on the cabinet body is to prevent that too much snow from coming the reaction with pressure sensor and leading to the snow to crush the roof and finally lead to the whereabouts of snow board 1 with the cabinet body along with bad thereby damage internals and important structure. The deep groove ball bearing 22 is adopted between the cam 17 and the cam seat 19 for transmission, so that the stable transmission can be ensured, the check rings 18 on two sides can prevent the eccentric load of the deep groove ball bearing 22.

The smooth friction degree of cam roof 37 surface is low, prevents to rub too big production of heat, thereby leads to the structure surface to produce the crack thereby to produce stress concentration and damage the structure thereby transmission that can not be smooth clear away snow and finally lead to the structure to damage. The upper end of the cam top 37 rod is connected with the snow-pushing plate 1 through a hinge, so that the cam can rotate stably. The mechanism is prevented from being abnormally operated due to the fact that the mechanism is blocked when the mechanism rotates. And finally the structure is damaged.
