Low-pressure carbon dioxide intelligent fire-fighting vehicle

Abstract

The invention discloses a low-pressure carbon dioxide intelligent fire-fighting vehicle, which comprises a vehicle provided with a rotary table, a storage tank, a refrigerating machine and an oil tank. The rotary table is provided with multiple stages of variable-amplitude arms; the front end of the top variable-amplitude arm is provided with a working arm assembly; the working arm assembly comprises a hydraulic motor, a key shaft, a hinged support, an air cylinder and a cylinder barrel; a hollow piston rod is arranged in the air cylinder and the cylinder barrel; the front end of the piston rod is fixedly connected with an impact head; a blind hole is arranged in the impact head; the front end of the impact head is provided with a plurality of jet holes; the front port and the rear port of the cylinder barrel are respectively and mutually connected with a reversing valve; the oil inlet of the reversing valve is mutually connected with an oil pump and the oil inlet of a bypass reversing valve; the working port of the bypass reversing valve is also mutually connected with a rear port on the cylinder barrel through a valve; and the connected oil line of the bypass reversing valve and the valve is provided with an energy accumulator. According to the low-pressure carbon dioxide intelligent fire-fighting vehicle disclosed by the invention, a gas extinguishing agent can be effectively conveyed to a high-rise, and meanwhile, the outer walls or doors and windows of a building are broken, thus, effective extinguishment can be implemented on the high-rise building or the interior of the high-rise building, and the long-term operation of equipment is ensured.

Description

technical field [0001] The invention relates to a low-pressure carbon dioxide fire engine. Background technique [0002] Existing fire trucks can extinguish fires in high-rise buildings, but they can only use water as a fire extinguishing agent; low-pressure carbon dioxide fire extinguishing has the advantages of environmental protection, safety, and economy, and can provide non-polluting and clean fire extinguishing for fires caused by water-avoiding substances. However, it is mainly used for indoor fixed automatic fire extinguishing. For high-rise buildings and their indoor mobile fire extinguishing, this method is not suitable, because the impact force of existing gas jet fire extinguishing is weak, and it is impossible to break windows or outer walls. Also there is no device that can effectively deliver gaseous fire extinguishing agents such as carbon dioxide to high-rises and simultaneously destroy the outer walls or doors and windows of buildings, thereby effectivel...

[0002] Existing fire trucks can extinguish fires in high-rise buildings, but they can only use water as a fire extinguishing agent; low-pressure carbon dioxide fire extinguishing has the advantages of environmental protection, safety, and economy, and can provide non-polluting and clean fire extinguishing for fires caused by water-avoiding substances. However, it is mainly used for indoor fixed automatic fire extinguishing. For high-rise buildings and their indoor mobile fire extinguishing, this method is not suitable, because the impact force of existing gas jet fire extinguishing is weak, and it is impossible to break windows or outer walls. There is also no device that can effectively transport gaseous fire extinguishing agents such as carbon dioxide to high-rise buildings and simultaneously destroy the outer walls or doors and windows of buildings, so that effective fire extinguishing cannot be implemented.
