Hydraulic door opening device

Abstract

The invention relates to a hydraulic door opening device. The hydraulic door opening device comprises an energy gathering bottle, a destroying bottle, a left connection lantern ring, a right connection lantern ring, a first bottle cap and a second bottle cap. The energy gathering bottle and the destroying bottle are spliced and connected to form an integral structure. The left connection lantern ring is arranged on the left end portion of the energy gathering bottle, and the right connection lantern ring is arranged on the right end portion of the destroying bottle. The bottom face of the energy gathering bottle is provided with an inner arc-shaped concave face which is concaved inwards, the destroying bottle is provided with a projectile convex face which protrudes upwards, the projectile convex face is matched with the inner arc-shaped concave face, and a gap for distribution of a detonating cord segment exists between the projectile convex face and the inner arc-shaped concave face. After the hydraulic door opening device is used, no killing fragments are generated, the door opening efficiency can also be guaranteed, and anti-terrorist rescue activities are safer, quicker and more efficient; and by means of connection lantern rings, a plurality of hydraulic door opening devices can be assembled together, and the detonation range is wider.

Description

Technical field [0001] The invention relates to the field of door breaking devices, in particular to a hydraulic door breaking device. Background technique [0002] At present, the doorbreaker system tools used by firefighting, security, and the military are mainly used to quickly enter apartments, factories and public places in emergency and difficult situations. The so-called emergency situation, such as a fire, the discovery of criminals, etc.; the so-called difficult situation, refers to the entrance of these places generally have layers of anti-theft doors. [0003] In today's market, for blasting residents' security doors and wooden doors, door-breaking bullets are used. Door-breaking bullets are bombs that use explosive energy to blast the door. Explosion refers to a physical and chemical process in which energy undergoes rapid transformation in a limited volume. In the process of this change, the internal energy is quickly converted into mechanical compression energy, lig...

AI Technical Summary

Problems solved by technology

In the early days, in order to ensure the effect of breaking the door, solid-state media were mostly used in door-breaking bullets. However, there are many problems with solid-state media. Safety of witnesses and others

For this reason, some door-breaking bullets use thin-shell materials and use directional high-pressure gas to break the door, but this only reduces the number of killing fragments, fails to solve the essential problem, and at the same time, the efficiency is very low
