[0035] The working principle of the carbon dioxide gas cannon in this utility model is as follows:

[0036] Liquid carbon dioxide is used as working medium, and high pressure gas can be generated by gasification. The high pressure gas can push the flower soil to simulate explosion, and can also be used as the opening and closing power of the pneumatic ball valve 8 to realize remote control without external power supply.

[0037] By controlling the gas pressure and the weight of the flower soil, the intensity of the simulated explosion can be controlled. The liquid carbon dioxide is naturally gasified, and the gasification energy is provided by the environment, so the system does not need external energy and external power supply. It is suitable for field operation.

[0038] The simulated explosion is a physical process, and there is no light, smoke, heat, toxic gas and explosion noise.

[0039] The carbon dioxide gas gun in the utility model has the following use process:

[0040] According to the needs of simulating explosion scale, angle and other needs, the gas gun is selected, and the scene is laid out and filled with flower soil.

[0041] The carbon dioxide storage bottle is used as a gas storage bottle to inject gas to the required pressure for standby. The gas can be injected at any time before use.

[0042] The output pressure of the pressure limiting valve 5 is adjusted to 0.6-0.8MPa to provide power for the opening and closing of the pneumatic valve. The pneumatic ball valve 8 is started by remote control device.

[0043] At the moment when explosion is needed, remote start is completed to simulate explosion.

[0044] The equipment is recovered and prepared for the next simulation.

[0045] Parameter description:

[0046] Through calculation and verification test, to realize the simulated explosion of 20kg flower soil thrown to 20m height, 1.5MPa pressure, 5L gas tank, DN50 pneumatic ball valve 8 and pressure limiting valve 5 are needed. The parameters can be adjusted according to needs.

[0047] The system can be integrated as a whole to facilitate layout. It can replace the explosion simulation of film and television fireworks in a relatively large range.

[0048] The principle and implementation mode of the utility model are described by applying specific examples in the utility model. The above embodiment is only used to help understand the method and core idea of the utility model; meanwhile, for general technical personnel in the field, according to the idea of the utility model, the specific implementation mode and application range will be changed.
