Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] like figure 1 , figure 2 As shown, the structural representation and the sectional view of the fire-fighting shell of the present invention are provided respectively, and it is made of projectile body 1, rear cylinder body 3, front cylinder body 4, explosive 5, fin 6, ignition powder, time-delay lead wire 8, instant The lead wire 9, the push ignition device and the ignition device at the front end are composed. The projectile body 1 shown is composed of fire-fighting materials. The interior of the projectile body 1 is a central cavity 2. 1's rear end and front end, and both communicate with the central cavity 2. There are multiple fins 6, and the plurality of fins 6 are evenly distributed on the periphery of the rear barrel 3, which is beneficial to enhance the stability of the shell during flight and prolong the flight distance. The explosiv...

The fire-fighting projectile of the present invention comprises a projectile body assembly and a propulsion assembly. The projectile body assembly consists of a projectile body, explosives, a rear cylinder, a front cylinder and a plurality of fins. The projectile body is made of fire-fighting materials. There is a central cavity, and the explosive is arranged in the central cavity. The characteristic is that the propulsion assembly is composed of a base plate, a piston, a return spring and a plurality of connecting plates. The rear ends of the multiple connecting plates are evenly fixed on the base plate, and the front ends are connected by The steel wire is fixed to the fins; the end of the rear cylinder is filled with igniting powder, which is connected to the explosive through a delay wire, and the piston is fixed in the center of the bottom plate for squeezing and igniting the igniting powder. The return spring is located on the bottom plate Between the airfoil and the fins, it plays a role in the separation of the fuse body assembly and the propulsion ignition assembly after being discharged from the chamber. The fire-fighting projectile of the present invention plays an insurance role through the position-limiting effect of the return spring and the connecting steel wire, and is beneficial to increase the shooting range of the fire-fighting projectile through the thrust effect of the propulsion assembly on the rear cylinder and the fins. The utility model has the advantages of simple structure, good fire extinguishing effect, remarkable beneficial effect and is suitable for application and popularization.
Description
technical field [0001] The invention relates to a fire-fighting shell, more specifically, to a fire-fighting shell capable of spraying fire-fighting substances on the surface of a burning object. Background technique [0002] As the saying goes, water and fire are ruthless, how to ensure the safety of people's lives and properties to the greatest extent in a fire is the main purpose of fire protection. However, with the construction of urbanization and the construction of factory buildings, when a fire occurs, the existing fire-fighting methods may not be able to achieve the fire-fighting effect. For example, when a high-rise building in a town is on fire, the existing fire extinguishing water guns may not be able to spray it; when a factory building with a risk of explosion is on fire, it is difficult to carry out fire extinguishing operations close to the fire area. To achieve a good fire extinguishing effect. For example, the patent No. is 2015109686317, and the inventi...
