Blank cartridge with anti-sympathatic-detonation function for deicing devices

Abstract

The invention discloses a blank cartridge with an anti-sympathatic-detonation function for deicing devices, comprising a cartridge case, a primer and a primer base. The primer base is arranged at theinner bottom of the cartridge case. The primer is arranged in the middle of the primer base and the cartridge case. A gun propellant is arranged above the primer base. A liner is arranged between thegun propellant and the cartridge case. A slider is arranged above the liner. A support block is arranged between the slider and the cartridge case. The support block is of an inverted barrel structure, and has a work hole in the top middle thereof. By changing the internal structure of the blank cartridge and adding a slider capable of moving up and down inside the blank cartridge, a barrier function is achieved, and the flame cannot be passed downward. Therefore, the problem of sympathetic detonation is solved, and a better using effect is achieved.

Description

technical field [0001] The invention relates to a blank bomb, in particular to a blank bomb with anti-explosion function used in a deicing device, and belongs to the technical field of power transmission line maintenance equipment. Background technique [0002] Because the ground wire of the transmission line is installed in the mountains, river valleys and the field, when it encounters rain and snow in winter, the ground wire will be covered with ice. The ice will be more serious than other sections, and the uneven and serious ice coverage may lead to insufficient clearance distance of the ground wire, which may lead to insufficient distance between the wire and the ground and crossing objects, resulting in accidents such as line tripping, and in severe cases, disconnection may occur. Events such as downed power lines, downed towers, downed poles, and deformation of equipment components have brought great operational risks to the safe and stable operation of transmission li...

[0002] Because the ground wire of the transmission line is installed in the mountains, river valleys and the field, when it encounters rain and snow in winter, the ground wire will be covered with ice. The ice will be more serious than other sections, and the uneven and serious ice coverage may lead to insufficient clearance distance of the ground wire, which may lead to insufficient distance between the wire and the ground and crossing objects, resulting in accidents such as line tripping, and in severe cases, disconnection may occur. Events such as downed power lines, downed towers, downed poles, and deformation of equipment components have brought great operational risks to the safe and stable operation of transmission lines. Whenever such special situations occur, the operation and maintenance management personnel will use deicing methods to eliminate hidden dangers. And the existing deicing all adopts blank bomb detonation work to carry out mechanical vibration deicing. The problem of martyrdom due to the impact of the impact caused the damage of the mechanical vibration deicing device or the damage of the ground wire, which greatly affected the development of the deicing work. This is a problem that needs to be solved
