Description
Technical field
The present invention relates to a kind of air-foam fire extinguisher, is a kind of improvement of handcart type air foam fire extinguisher structure specifically.
Background technology
For one of method that occurs in tunnel, colliery, airport, oil cellar, garage, boats and ships, warship and put out a fire to save life and property at the fire that causes by water-insoluble inflammable, flammable wandering liquid of the confined space, be to adopt air-foam fire extinguisher.So-called air-foam fire extinguisher, mix mutually with water and air by fire foam exactly, produce foam, cover the surface of water-insoluble inflammable, flammable, the liquid that can scatter of burning, make it and contain the air insulated of oxygen that can be combustion-supporting, thereby water-insoluble burning inflammable, flammable, the liquid that can scatter is extinguished.Said fire foam, having a kind of is that hydrolysis concentrate with animal protein is a base-material, an amount of additives such as stabilizing agent, anticorrisive agent and antifreezing agent are made in addition.The Chinese patent application 200810140306.1 that applicant was submitted in 2008 discloses a kind of air-foam fire extinguisher, said air-foam fire extinguisher is a kind of backpack fire extinguisher, comprise that the pipe tooth connects button, imbibition joint and sebific duct, said imbibition joint has valve, said imbibition joint links by sebific duct and fire foam bucket, and it comprises that also double end is external, the fluid by-pass valve control, double end connects silk, collector, the imbibition chamber disperses baffle plate, copper sheathing, nozzle and foaming tube are packed said fire foam in the backpack extinguishing chemical bucket into, and the extinguishing chemical bucket links by the imbibition joint of sebific duct and air-foam fire extinguisher.During use, the extinguishing chemical bucket is carried on the back on user's shoulder, the pipe tooth that fire extinguisher canvas hose is connected on air-foam fire extinguisher connects to be buckled, the tube subtend that will foam ignition zone, open fire extinguisher canvas hose, to go out hydraulic control valve opens gradually, the water of High Voltage will connect by the pipe tooth and tip in into collector, sucks fire foam from the imbibition joint, disperses baffle plate by frustum, enter nozzle, form powerful pressure, mix the foam that the back forms with inhaled air, diffusion atomizing immediately, again through foaming tube tube head, form powerful negative pressure once more, suck a large amount of air, so that form the high speed foam stream, be sprayed in the foaming tube cylinder, pass through the bump with silk screen again, further form more foam, spray and cover the water-insoluble inflammable of burning, flammable, can the scatter surface of liquid, make it and contain the air insulated of oxygen that can be combustion-supporting, thereby burning is extinguished.But, when said foam annihilator uses in fire extinguishing, there are several problems: at first, because said foaming tube is the big cylinder of mid diameter, the air of ejection can consume part energy when being ejected into the different cylinder side wall of diameter, lower the speed that foam stream sprays, made the jet length of foam be affected; In addition, must carry froth liquid vessel and be connected use, and the two carrying is born by the fire fighter, is not easy very much, give fire fighter's overcharge, must bring negative effect for the efficient of fire-fighting with said foam annihilator; Secondly, said air-foam fire extinguisher support one end is fixed in cylinder, and the other end is fixed in a head, makes whole air-foam fire extinguisher seem long, is not very convenient in scene of fire carrying and use; Moreover, limited after all by the froth liquid vessel volume and weight that fire fighter's human body is born, be not enough in order to stamping out a fire, and replenish fire foam in the scene of fire, both wasted time labor intensive again, the efficient of influence fire extinguishing.
Before technical solution of the present invention is finished, not seeing the handcart type air foam fire extinguisher identical with structure of the present invention uses in daily life, not seeing the handcart type air foam fire extinguisher identical with structure of the present invention has sale on market, it is on the books in the literature also not see the handcart type air foam fire extinguisher identical with structure of the present invention.
Summary of the invention
The object of the present invention is to provide a kind of handcart type air foam fire extinguisher, can make in the use the air that produces spray than existing air-foam fire extinguisher and spray farther distance, reduce casualties or property loss, minimizing is to fire fighter's injury, when work, can carry weight and volume than bearing much more fire foam, all fire-extinguishing apparatus are carried and moved is not to bear by the fire fighter, but by go-cart, alleviate fire fighter's burden, save the time and the manpower that replenish fire foam, improve fire-fighting efficiency.
