Embodiment Construction

[0007] When the line first freezes, in the normal power supply state, line maintenance personnel use special crossbows to launch icicles and wooden sticks from the ground to the ice and snow on the air line and the tower to smash the ice and snow. The special crossbow is composed of bow 1, bow string 3, crossbow handle 6, trigger 4, launch tube 2, sight 5, etc. The launch tube 2 has an inner diameter of 30 mm, and launches cylindrical icicles, wooden sticks and plastic thermos bottles with a diameter of 30 mm. , It can instantly crush, knock down, and clear the ice and snow on the transmission line and the tower, so as to avoid the leakage and power failure of the transmission line due to the freezing and snow accumulation.

Abstract

The invention discloses an instant safe deicing method of power transmission line and a deicer thereof, which can shoot an object to break and strike the ice and snow on an aerial line and a tower frame by a shooting tool from the ground by an operator when ice is just occurred on the line. Accordingly, aerial operation can be changed into ground operation, power-off maintenance into power-on maintenance, and the method can instantly and safely remove ice and snow on the power transmission lines to prevent an electric leakage and power-off faults due to the accretion of ice and snow. The shooting tool is a special crossbow with a transmitting tube of a larger inner diameter, and the object to be shot is cylindrical icicle, crabstick, rubber stick, plastic stick, or plastic vacuum flask and burning bottle consistent with the inner diameter of the transmitting tube. The icicle and the crabstick can strike the ice and snow and the vacuum flask and the burning bottle can eliminate ice and snow on key portions.

Description

technical field [0001] The invention relates to a method for deicing power transmission lines in winter and a deicing machine tool thereof, in particular to a method for instant and safe deicing of power transmission lines and a deicing machine thereof. Background technique [0002] During the ice and snow disaster in southern my country this year, due to the freezing of power transmission lines, there were leakage and power outages. After the weight of the ice exceeded the load-bearing capacity of the wires and iron towers, it even caused the lines to fall and the iron towers to collapse. At present, power transmission lines are completely deiced manually, and maintenance personnel can only operate on the iron tower when the power is off. The work is dangerous and the efficiency is low. Contents of the invention [0003] The invention provides an instant and safe deicing method for a power transmission line and a deicing machine thereof, which can be deiced immediately by...
