TH455B - Underwater cutting tools - Google Patents

Abstract

Tools for cutting steel, concrete or similar objects underwater include Oxygen delivery rod (10) which has been modified to be connected to the oxygen source (24, 25) and has a pistol grip. (16) before using it for the first time The oxygen delivery rod is plugged to ensure safe ignition while underwater. This blocking unit (12) will explode or dissolve by means of the ignition unit (14) which is effective underwater. Oxygen is also injected from the delivery rod (10) at the same time. The stopper (12) is made up of highly flammable material. Or at least it contains flammable materials. It has the property of effectively filling the end of the transmission rod (10) as well.

Claims (9)

1. A tool for underwater cutting. Consists of (a) a grip base that can be flexibly attached to the oxygen source; (b) a thermal cutout attached to the aforementioned grip base at one 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 detonation unit of the said cutting tip ( E) the thermal cutter head, the opposite end of the cutting tip, is closed; (f) the shank base has a section for drilling the heat cutter head against the cutting end for Let the oxygen flow into the thermal cutter 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 stopper 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 enclosed 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
