Embodiment Construction

[0013] The underwater explosive perforating projectile of the present invention comprises a projectile body 1, which can be a cube or a cuboid cylinder, and has a blind hole 2 in the center of the projectile body 1, and the bottom of the blind hole 2 is filled with a propellant 3, and the hole is punched. The warhead 4 is placed in the blind hole 1 above the propellant 3 . The conical top of perforating warhead 4 adopts high-hardness alloy steel to make. The bottom of the blind hole 2 is also provided with a lead through hole 5 . The detonator 6 is buried in the propellant 3, and its lead wire 7 is ejected from the projectile body 1 along the lead wire through hole 5. Detonation detonator 6, lead wire 7, detonation power source 10-1 and switch K1 form detonation circuit, after closing switch K1, can detonate detonator, ignite propellant charge 3 thereupon, thereby perforating warhead 4 is launched.

Abstract

The invention relates to an underwater explosive perforation bullet which is characterized by comprising a bullet body; a blind hole is disposed on the bullet body and sequentially provided with propellant powder and a perforation bullet, and a leading wire through hole is disposed on the bottom of the blind hole; a primer cap is buried in the propellant powder, and a leading wire of the primer cap is exposed out of the bullet body along the leading wire through hole. By utilizing the electromagnetic theory, the underwater explosive perforation bullet is absorbed on a hull part needing perforation, then the bullet is pushed by the powerful pressure generated by dynamite exploitation to impact an armor plate of the hull, thereby a hole with the same diameter with the bullet is drilled on the hull. The underwater explosive perforation bullet can conveniently, rapidly and easily drill the needed hole on the submerged armor plate hull.

Description

technical field [0001] The invention relates to a perforating device, in particular to an underwater explosive perforating bomb used in salvage of sunken ships. Background technique [0002] During the salvage process of the sunken ship, it is usually necessary to select a suitable hole on the sunken ship so that the hoisting wire rope can be hung thereon, and then the sunken ship is salvaged out of the sea by external lifting equipment. However, due to the varying degrees of damage of the sunken ships and the complex terrain conditions of the seabed, it is often impossible to find suitable holes. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defective of prior art, provide a kind of underwater explosive perforating bomb that can punch out required holes on the shipwreck steel plate hull conveniently, quickly and easily underwater. [0004] Technical scheme of the present invention is: [0005] An underwater ex...
