Cannon body structure of supercritical carbon dioxide gas cannon

Abstract

The invention provides a cannon body structure of a supercritical carbon dioxide gas cannon. The cannon body structure is used for emergency rescue in earthquake relief work, emergency relief and other occasions, and is composed of three parts, namely a carbon dioxide liquid filling assembly, an accelerating section assembly and a cannon barrel assembly. According to the cannon body structure, magnesium powder in a heating pipe releases a large amount of heat after being ignited through an electric spark, so that the temperature and the pressure of carbon dioxide in the liquid filling pipe aresharply increased, and the supercritical state is quickly achieved; when the pressure exceeds the damage limit of a rupture disk, the carbon dioxide is rapidly jetted to push a cannonball; and an acceleration connecting section is composed of an acceleration section and a recoil section, so that the outlet speed of the cannonball is remarkably increased, and meanwhile the length of a cannon barrel is remarkably reduced. The cannon body structure has the advantages of simple structure, safety, reliability, rapidness in filling, portability and high efficiency, and is suitable for emergency rescue.

Description

technical field [0001] The invention relates to a gas cannon, more specifically, a cannon body structure of a supercritical carbon dioxide gas cannon. Background technique [0002] In occasions such as earthquake relief and emergency rescue, blasting equipment with long operating distance, high safety and stability, and good portability is required. However, traditional artillery is destructive, dangerous, and low in maneuverability, so it is not suitable for emergency rescue. The gas cannon is a device that uses the principle of aerodynamics, uses compressed gas as the working medium, and uses a differential pressure device and a quick exhaust valve that can realize automatic control to instantly convert the gas pressure energy into the kinetic energy of the air jet and generate a strong impact. The gas cannon has the ability to launch projectiles at high speed, and its shock loading can generate a shock wave pressure of hundreds of MPa to hundreds of GPa in solid material...

AI Technical Summary

Problems solved by technology

However, the gas cannons of existing light gas are highly dangerous due to the gas, and the energy consumption is large when compressing the gas, and the structural design characteristics of the existing gas cannons cause them to have relatively large recoil, and the length of the barrel is relatively long , and requires a large amount of ammunition, the safety needs to be further improved, the cost is relatively high, and the loading speed is relatively slow, and there are many auxiliary equipment, which is difficult to carry, which affects the popularization and application of gas cannons
