Pneumatic fire extinguishing gun system

Abstract

The invention discloses a pneumatic fire extinguishing gun system. The pneumatic fire extinguishing gun system comprises an air gun, an electric cylinder, a support plate, a recoil device and a base;the base is movably fixed onto the recoil device through a rotary support; the base is provided with a motor; the air gun is fixed onto the base through the support plate and the electric cylinder; the air gun is provided with a gun sight; the air gun comprises a gun barrel, an air chamber, a front trunnion and a rear trunnion; the rear end of the gun barrel penetrates through the air chamber andis fixed to the air chamber, and the end part of the gun barrel is provided with the rear trunnion; the rear end of the air chamber is fixedly provided with an end cap; a seal ring I is arranged at the joint of the front end of the air chamber and the gun barrel; the gun barrel at the front end of the air chamber is provided with the front trunnion; a seal ring III is arranged between the end capand the gun barrel; and a piston is arranged in the air chamber. According to the pneumatic fire extinguishing gun system disclosed by the invention, by employing a pneumatic launching means, the potential safety hazard of an initiating explosive device is avoided; the air gun is compact in structure, simple in air channel, controllable in cost and high in reliability; and height and azimuth adjustment is performed by employing the electric cylinder and the motor, and the gun sight is equipped, so that the fire extinguishing gun is very high in sight precision.

Description

technical field [0001] The invention relates to a fire extinguishing cannon system, in particular to a pneumatic fire extinguishing cannon system. Background technique [0002] Fire extinguishing cannon is a new type of fire extinguishing equipment that has emerged in recent years. It can deliver fire extinguishing bombs to the fire scene from a long distance to avoid personal safety problems caused by close-range operations. Typical ones include SLM-60 individual shoulder-resistant fire extinguisher, SLM-105 bracket type fire extinguisher, CMH-1 long-distance intelligent forest fire extinguishing artillery system, etc., but the existing fire extinguishers are mainly driven by gunpowder gas Launching projectiles or using rocket engines as the power source for launch involves certain safety hazards in the storage, transportation, and use of the explosives involved, and the use in the civilian field faces strict restrictions on policies and standards, making it difficult to po...

Problems solved by technology

Typical ones include SLM-60 individual shoulder-resistant fire extinguisher, SLM-105 bracket type fire extinguisher, CMH-1 long-distance intelligent forest fire extinguishing artillery system, etc., but the existing fire extinguishers are mainly driven by gunpowder gas Launching projectiles or using rocket engines as the power source for launching, the explosives involved in them have certain safety hazards in storage, transportation, and use, and their use in the civilian field faces strict restrictions on policies and standards, making it difficult to popularize and apply

CN 200510012974.2 discloses a bracket-type pneumatic fire extinguisher, but its shooting range is short (only 210m), and the height and orientation of the bracket are adjusted manually, which is inconvenient to use

CN201510538150.2 proposes a mechanical continuous pneumatic fire extinguisher, but the structure is complex, the volume is huge, and the influence of recoil is not fully considered
