Problems solved by technology

Gas high-pressure tanks need to be transported after production. However, in the conventional mode of transport, if an accidental traffic accident occurs, the high-pressure tanks may collide, rupture and explode. Therefore, the danger is extremely high, and a special mode of transport must be adopted. Further increase the cost and risk of production
[0003] Gas liquid is often corrosive to a certain extent, and will corrode the inner wall of the aluminum alloy high-pressure tank for a long time, and then corrode and penetrate, greatly shortening the service life of the product itself, so that the general storage life of the existing high-pressure tank is about 3 years , in addition to further increasing the risk of high-pressure tank explosion
Finally, for the material of the high-pressure tank, the existing high-pressure storage method needs to meet its high-pressure properties and its corrosion resistance characteristics at the same time, which in turn increases the corresponding material cost

Abstract

A police tear gas injection device comprises an injection gun head, a controller, a storage tank, a piston, a thrust unit and an end cover, a hollow cavity matched with the piston in a sealed piston mode is formed in the storage tank, and the piston isolates the hollow cavity into an upper cavity used for storing tear gas and a lower cavity used for installing the thrust unit in a sealed mode. The upper chamber is connected with a spraying gun head, and an opening matched with the end cover in a covering mode is formed in the outer end of the lower chamber; the thrust unit is fixedly installed on an installation face arranged on the inner side of the end cover, the thrust unit comprises a lifting rod and a power device, the telescopic top is in abutting fit with the lower end of the piston, the power device is connected with the lifting rod, and the power device is used for controlling the lifting rod to stretch out and draw back; the controller is connected with the power device and used for controlling starting and stopping of the power device.

Description

Technical field [0001] The present invention relates to the field of tear gas injection device, specifically to a police tear gas injection device. Background [0002] The existing police tear gas injection device adopts the tear gas set in the high pressure tank, when in use, open the valve can make the tear gas liquid in the high pressure tank mixed with high pressure gas high pressure injection out. First of all, because the hydraulic strength of the gas stored in the high-pressure tank reaches an average of 4 MPa, whether it is a shoulder-backed or handheld high-pressure bottle tear gas disperser, if it accidentally falls to the ground or collides and occurs at high temperatures, fires, etc. are prone to explosion, once it occurs, it will definitely cause casualties and property losses, and once the explosion occurs, the harm caused by the explosion is extremely great, and the consequences are very serious. Due to the danger of gas high pressure tanks, the parameters in the a...
