High voltage line automatic deicing mechanism capable of adjusting ice-breaking position

Abstract

The invention discloses an automatic deicing mechanism for high-voltage lines with adjustable ice breaking position, relates to the technical field of protection equipment for overhead power transmission cables, and solves the problem that the distance between the cutter heads of the existing deicing mechanism cannot be adjusted or can only be disassembled and assembled at the construction site. The ice breaking position of the blade can only be adjusted under the condition of the machine structure, which includes the casing, the driving wheel and the driven wheel are installed on the casing, the driving motor and the worm gear mechanism are arranged in the casing, and the front end of the worm protrudes from the casing and is connected to a The rotating body rotates with the rotation of the worm. The rotating body is equipped with a mechanical deicing mechanism. The mechanical deicing mechanism includes a rotating column and a plurality of blades uniformly arranged radially along the rotating column. The rotating column is equipped with a blade for adjusting the locking position of the blade. The locking mechanism, through the implementation of this technical solution, can effectively avoid the problem that the distance between the cutter head of the deicing mechanism cannot be adjusted or the ice breaking position of the blade can only be adjusted when the whole machine structure is disassembled at the construction site, and it is suitable for removing ice with different diameters. Overhead lines covered with ice.

Description

technical field [0001] The invention relates to the technical field of protection equipment for overhead power transmission cables, and more particularly relates to an automatic deicing mechanism for high-voltage lines with adjustable ice breaking positions. Background technique [0002] Icing of transmission lines in winter is one of the natural disasters of the power system. Due to the increased ice load on the conductors, it will cause certain mechanical damage to the conductors, iron towers and fittings. When the ice is severe, the wires will be disconnected, the towers will be inverted, the conductors will dance and flashover and trip, resulting in large-scale power outages. Because the accident occurred in the severe winter season, the mountain was blocked by heavy snow or the road was icy, which made the emergency repair conditions very difficult, resulting in a long-term power outage, which seriously threatened the safe and stable operation of the power grid and the ...

AI Technical Summary

Problems solved by technology

However, this technical solution still has the following deficiencies: 1. Only the mechanical deicing method of percussion and vibration is used, and its effect on icing with strong binding force and thick ice layer such as rain rime and mixed rime is limited, and the deicing effect Not good; 2. The thermal deicing mechanism fixed on the transmission line is easy to cause damage to the interior of the transmission line due to the continuous heating of the thermal deicing mechanism; 3. General mechanical deicing cannot adapt to the icing of overhead lines of different diameters. The cutter head of the deicing mechanism cannot adjust the distance or can only be disassembled and adjusted at the construction site, which is complicated to operate
