Gas-liquid buffered high-pressure gas water bomb launcher

Abstract

The invention discloses a gas-liquid buffered high-pressure gas water bomb launcher, which comprises an accelerator cylinder and a buffering cylinder, wherein the upper end of the cylinder body of the accelerator cylinder is connected with an upper end cover of the accelerator cylinder; the lower end of the cylinder body of the accelerator cylinder is connected with a lower end cover of the accelerator cylinder; a piston and a buffering ring are mounted inside the cylinder body in a vertically movable manner; the upper end cover of the accelerator cylinder is connected with the lower end cover of the buffering cylinder; an inner cylinder body, an outer cylinder body, the upper end cover and the lower end cover of the buffering cylinder form an annular cylinder in which an annular piston is arranged; the annular piston is provided with at least three piston rods which extend out of the lower end cover of the buffering cylinder to be inserted into the accelerator cylinder; the piston rods are connected with the buffering ring inside the accelerator cylinder; an annular groove is formed in the upper surface of the piston of the accelerator cylinder; the section of the annular groove is inverted T-shaped; the annular protrusion structure of the buffering ring is in clearance fit with the annular groove; four V-shaped grooves of different lengths are circumferentially formed on the annular protrusion structure of the buffering ring at intervals of 90 degrees; the lower part of a water retaining tube is connected with the inner side of the buffering ring; and the upper part of the water retaining tube is inserted into the centre hole of the buffering cylinder. The gas-liquid buffered high-pressure gas water bomb launcher has a long range.

Description

technical field [0001] The invention relates to a water bomb device, in particular to a high-pressure gas launching water bomb device. Background technique [0002] The pace of urbanization in China is accelerating, and there are many high-rise buildings with more than 20 floors in large and medium-sized cities. Fire protection on high floors is a major issue. The performance of the fire water cannons (guns) currently equipped is insufficient, and they can only reach a height of 30 to 40 meters, and cannot carry out effective external suppression. When attacking internally, the heroic firefighters paid a high price of casualties. Therefore, my country is in urgent need of long-range high-power fire-fighting water cannons. [0003] The technical defect that existing long-distance water cannon exists: shooting range is shorter. Contents of the invention [0004] In order to overcome the shortcomings of the short range of the existing high-pressure pulse water cannon, the p...
