Abstract

A gas piston-type movable guide pipe net opening device includes a catch net (8), a traction head (6), a guide pipe (7), an igniter (3), a main charge (5), a gas generator (1) and Piston (2). The piston and main charge are placed in the gas generator. The top of the piston contacts the triangular projection on the base of the guide tube. The traction head is placed in the guide tube, and the other end of the traction head is tied to a corner of the catch net. When working, the igniter ignites the main charge, and the gas produced pushes the piston to move, and the piston pushes the guide tube to move. The gas enters the guide tube, pushes the tractor to fly out of the guide tube, and the tractor drives the catch net to open. This kind of gas piston type movable guide pipe net opening device has a fast deployment speed and a large area of ​​the deployment and capture net.

Description

technical field [0001] The invention relates to a net opening device, in particular to a gas piston type movable guide pipe net opening device. Background technique [0002] At present, the more mature capture net systems at home and abroad are mainly police "net guns". The net opening device of the "net gun" is mainly composed of a firing mechanism, a high-pressure gas cylinder, a fixed guide tube, a traction head and a catch net. The net opening device uses the power provided by the high-pressure gas cylinder to push the traction head along a fixed The pipeline accelerates, and each traction head drives a corner of the catching net to take the net out, thereby realizing the opening of the catching net. The disadvantage of the "net gun" net opening device is that the angle of the accelerating pipe is small and the stroke is short, so the area of ​​the catching net that can be opened is small. If the angle and stroke of the accelerating pipe are to be increased, the overall...
