Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] refer to figure 1 , a high-pressure gas launching water bomb device, including two parts of an acceleration cylinder and a buffer cylinder, the acceleration cylinder is composed of a cylinder body 2, an upper end cover 6, a lower end cover 1, a piston 3 and a buffer ring 5, and the buffer cylinder is composed of an inner and outer cylinder body 10 and 11, the buffer cylinder upper end cover 9 and the buffer cylinder lower end cover 12 are formed into an annular cylinder. There is an annular piston 8 in the cylinder, and 3 piston rods are installed on the piston 8, which protrude from the buffer cylinder lower end cover 12 and are inserted into the acceleration cylinder. The buffer ring 5 in the acceleration cylinder is connected. The bottom of the water retaining cylinder 13 is connected to the inner side of the buffer ring and can move together with the buffer...

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...
