High-pressure gas water-bomb firing apparatus

Abstract

The invention provides a high-pressure gas water-bomb firing apparatus which comprises an acceleration cylinder and a cushion cylinder. In the acceleration cylinder, the upper end of an acceleration cylinder body is connected with an upper end cover of the acceleration cylinder, the lower end of the acceleration cylinder body is connected with a lower end cover of the acceleration cylinder, a piston capable of moving up and down is installed in the acceleration cylinder body, a buffering ring capable of moving up and down is installed in the acceleration cylinder body, and the upper end cover of the acceleration cylinder is connected with a lower end cover of the cushion cylinder; in the cushion cylinder, an inner cylinder body is located in an outer cylinder body, an upper end cover of the cushion cylinder is respectively connected with upper ends of the inner cylinder body and the outer cylinder body, and the lower end cover of the cushion cylinder is respectively connected with lower ends of the inner cylinder body and the outer cylinder body; an annular piston is arranged in an annular cylinder, at least 3 piston rods are mounted on the annular piston, extend out from the lower end cover of the cushion cylinder and are inserted into the acceleration cylinder, and the piston rods are connected with the buffering ring in the acceleration cylinder; and the lower part of a water retaining drum is connected with the inner side of the buffering ring, and the upper part of the water retaining drum is inserted into a central hole in the cushion cylinder. The high-pressure gas water-bomb firing apparatus provided by the invention has a long firing 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 shooting range of the existing high-pressure pulse water cann...
