TH996A - Underwater cutting tools - Google Patents

Abstract

Submersible tools for cutting steel, concrete or similar objects include The oxygen delivery rod (10) has been modified to be attached to the oxygen source (24, 25) and has a pistol grip. (16) before using for the first time Oxygen emitter rods are sealed to provide safety to ignite while underwater. The stopper (12) explodes or dissolves by means of the ignition (14), which is effective underwater. In this case, oxygen is injected out of the sender rod (10) at the same time by a plug (12) made up of highly flammable materials. Or at least a mixture of flammable materials. It has the ability to effectively block the tip of the transmission rod (10) too.

Claims (9)

1. A tool for underwater cutting. It consists of (a) a grip base that can be flexibly attached to the oxygen source (b) a thermal cutter fixed to such a grip base at the end and There is a waterproof plug on the cutting end on the opposite side. (C) The watertight plug is made of flammable material (d) the ignition and ignition set, the waterproof plug on the cutting end ( E) the thermal cutter head, the opposite of the cutting tip, is closed; (f) the shank base has a section for drilling the thermal cutter at the end of the cutting end to Let the oxygen flow into the cutting head at a pressure higher than the pressure of the surrounding water. 2. The underwater cutting tool, as in claim 1, is unique in that the stopper at the end adjacent to the base of the handle can be opened with a needle embedded in the base of the handle. It can move in the longitudinal direction of the cutting head. And has a channel for oxygen to flow along the axis 3.The underwater cutting tool, as in claim 2, is unique in that the needle is attached to the trigger, which attaches the rotatable to the base of the handle in such a way that when the trigger moves, the needle will pierce the stopper at the end. Adjacent to the base of the handle 4. The underwater cutting tool, as in claim 3, is unique in that the provision of an electric switch for electric ignition of the ignition unit. 5. The underwater cutting tool, as in claim 4, is unique in that the electrical switch can be activated by a separate switch. After drilling the stopper at the end adjacent to the base of the handle. 6. The underwater cutting tool, as in claim 5, is unique in that the ignition unit consists of an electric igniter with at least one heating wire. Which is encapsulated with combustible substances and where the generated ignition can be connected to the terminal of the power source By the ignition switch installed in the base of the handle. 7. The underwater cutting tool, as in claim 6, is unique in that the electric ignition unit is attached to the inside of the plug at the free end of the cutter head. With the electrical connection of the ignition unit through to the ignition switch 8. The underwater cutting tool, as in claim 7, is unique in that the ignition unit contains a material which is flammable by a chemical reagent. The chemical reagent is brought into contact with the combustible substance as soon as oxygen flows into the cutting head. 9. The underwater cutting tool, as in claim 8, is unique in that the chemical reagent is contained in a thin glass bulb or similar container within a stopper that covers the free end of the cutter head. The glass bulb will break when exposed to high pressure from the oxygen flowing into the cutting head. Where the reagent is in contact with the combustibles inside of the stopper
