Adjustable underwater explosion jet pipe mounting and dismounting tool

Abstract

The invention provides an adjustable underwater explosion jet pipe mounting and dismounting tool, comprising a first shaft barrel, a second shaft barrel, a first shaft and a second shaft that are arranged in the first shaft barrel and the second shaft barrel respectively through bearings, an adjustable telescopic rod mechanism that is arranged between the outer portion of the first shaft barrel and the outer portion of the second shaft barrel, a gear box, and a first gear and a second gear that are arranged in the gear box. The second gear is meshed with the first gear; the second gear is mounted on a third shaft; the end of the third shaft extends out of the gear box and is provided with an installation sleeve for installing a jet pipe, one end of the second shaft extends into the gear box, the first gear is installed on the second shaft, one end of the first shaft is provided with a rotation driving mechanism, the other end of the first shaft and the other end of the second shaft areconnected with couplers respectively, and a universal joint is arranged between the two couplers. The adjustable underwater explosion jet pipe mounting and dismounting tool is used for solving the problems that an existing jet pipe is inconvenient to mount and dismount underwater, and harm is caused to a human body. Meanwhile, the device is low in cost and simple in structure, and the experimentefficiency is improved.

Description

technical field [0001] The invention relates to an adjustable underwater explosion jet tube installation and removal tool, which belongs to the field of underwater explosion bubbles. Background technique [0002] The bubble jet load of underwater explosion is an important part of the wall pressure of near-field underwater explosion. Essentially, the bubble jet load is caused by the macroscopic high-speed impact of water. Since the jet tube is placed underwater, there is a relative amount of water in the jet tube cavity, and the formation of the lure jet is to place a small equivalent gunpowder at the end cap of the jet tube. The gunpowder explodes and then releases a large amount of gas, which pushes the water in the jet lumen, thereby generating a high-speed jet. The jet tube provides the jet field for impact experiments. This plays a vital role in projects such as research on the protection of ships and submarines. [0003] The current jet impingement test platform has ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an adjustable underwater explosion jet tube installation and removal tool in order to overcome the difficult problem of installing the jet tube underwater. Since the used explosion source in the underwater explosion experiment is gunpowder, after the gunpowder explodes, Produces residual substances in water, accompanied by pungent smell, which has certain harm to human body
