Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] refer to figure 1 , a high-pressure gas launch water bomb device buffered by an airbag, comprising two parts of an acceleration cylinder and a buffer cylinder, the acceleration cylinder is composed of a cylinder body 2, an acceleration cylinder upper end cover 6, an acceleration cylinder lower end cover 1, a piston 3 and a buffer ring 5, the buffer The cylinder is an annular cylinder composed of an inner cylinder body 10, an outer cylinder body 11, an upper end cover 9 of the buffer cylinder and a lower end cover 13 of the buffer cylinder. There is an annular piston 12 in the cylinder, and three piston rods 7 are installed on the piston 8. From the lower end of the buffer cylinder The cover 13 stretches out, is inserted in the acceleration cylinder, and is connected with the buffer ring 5 in the acceleration cylinder. One of the three piston rods has a through ...

An air bag buffered high pressure gas water shell firing device comprises an accelerating cylinder and a buffering cylinder, wherein the accelerating cylinder comprises a cylinder body; the upper end of the cylinder body is connected with the upper end cover of the accelerating cylinder; the lower end of the cylinder body is connected with the lower end cover of the accelerating cylinder; a piston and a buffering ring are mounted in the cylinder body and can move up and down; the upper end cover of the accelerating cylinder is connected with the lower end cover of the buffering cylinder; the inner cylinder body of the buffering cylinder is positioned in the outer cylinder body of the buffering cylinder; the upper end cover of the buffering cylinder is connected with the upper ends of the inner cylinder body and the outer cylinder body respectively; the lower end cover of the buffering cylinder is connected with the lower ends of the inner cylinder body and the outer cylinder body respectively; a ring piston is arranged in the ring cylinder (namely the buffering cylinder); at least three piston rods are mounted on the ring piston; a through hole is formed in one of the piston rods; a throttle valve is connected with and fixed to the upper end of the through hole; the lower end of the through hole is communicated with an air bag buffer; the air bag buffer adopts a ring structure and is mounted on the buffering ring; 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 in the center hole of the buffering cylinder. The air bag buffered high pressure gas water shell firing device 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 range of the existing high-pressure pulse water cannon, the p...
