Abstract
A water-gun booster is a fire-fighting equipment, and is installed to water gun to raise the jet pressure and flow rate and fire distinguishing efficiency, or connected to fire fighting hose to raise water jet lift. The equipoment consists of mainly water pump, pneumatic motor and air flow regulating valve, and is powdered by compressed air. It is simple, reliable, light in weight small in volume, large in output power and easy to carry about, and so it is especially suitable for use in raising water pressure during distinguishing fire of high-rise building.
Description
Booster for fire fighting water gun is a kind of fire-fighting fire-extinguishing equipment.It can be connected on the fire-fighting fire extinguishing hydraulic giant, improves the jet pressure of Fire water syringe, increases fire extinguishing effectiveness.
Urban architecture at present is more and more higher, usually occurs the not enough usefulness that has influenced fire-fighting fire extinguishing of hydraulic pressure because of fire-extinguisher water hose when fire-fighting fire extinguishing has been brought high-rise fire extinguishing.Because the compression resistance of software fire-extinguisher water hose is low, has limited the height that fire-fighting truck supplies water and can arrive.Or supply water and to have reached needed height, but the pipeline and the pressure loss that highly causes are many, make that the jet power of Fire water syringe is little, and the bulk range of current is near, and the sputter area of the hitting power of water column and spray is less.Thereby reduced the usefulness of fire extinguishing widely.Though tall building self in the world all has fire-protection equipment and automatic fire extinguishing system at present, but, if run under the special situation, for example the power supply system in the building breaks down, water pump in the building can't start, and the water supply of the soft band of water delivery of outside fire-fighting truck at this moment is highly low, and the big fire of top of high-rise buildings just can't be put out effectively.Present existing pipeline mounted pump can play the pressure of supply water that increases fire-extinguisher water hose.But the power system of present pipeline mounted pump generally is with motor and gasoline engine driven.The two weight more very much not is easy to carry.When unregulated power, electronic pipeline mounted pump just can't be worked.And the gasoline in the gasoline engine driven pipeline mounted pump is not suitable for using in the scene of a fire very much.
The objective of the invention is to design a kind of device that can increase the jet pressure of hydraulic giant on the fire-fighting lance that is installed in.It simple in structure, reliable performance, volume is little, in light weight, conveyance power of water big, be easy to carry, with the hydraulic pressure pressurized machine of compressed air-driven.When the pressure of supply water deficiency when fire extinguishing, occurring, easily this device is connected, both can increase the water delivery height of fire-fighting truck software water band, can strengthen the injection rate of Fire water syringe again, improve fire extinguishing effectiveness.
The present invention realizes like this.Booster for fire fighting water gun is mainly become with pneumatic groups of motors by water pump.The structure of the import and export of water pump can connect fast with the fire-extinguisher water hose and the Fire water syringe of standard.The impeller of water pump is contained on the output shaft of pneumatic motor.Pneumatic motor is provided with barometric damper.The handle of control valve changes the opening amount control of modulating valve and imports the rotating speed that the interior air supply of motor is reconciled motor.Thereby reach the flow of control of pump outlet and the size of pressure.The main structure of this device adopts lightweight material to make.
Advantage of the present invention:
1, is power source with pressurized air, can in the non-transformer scene of a fire, uses safely.
2, this apparatus structure is simple, volume is little, in light weight, output power big, be easy to carry.Be with 1/80th-ten of the electronic pipeline mounted pump weight of power.The higher output power and the characteristics of weight ratio are well suited for the fire-fighting occasion that need go into battle with a light pack.
When 3, the import and export of pressurized machine being connected with fire-extinguisher water hose, can also increase the water delivery height of the soft water band of fire-fighting as the pipeline mounted pump segmentation.Solve fire-fighting truck and increased water delivery ability highly.
4, change the size of the charge flow rate may command Fire water syringe jet power of pressurized machine.In the time of can satisfying different fiery condition to the demand of the water yield and hydraulic pressure.
Accompanying drawing is the structural representation of booster for fire fighting water gun of the present invention.Provide ins and outs of the present invention below in conjunction with description to the embodiment of accompanying drawing.
Booster for fire fighting water gun of the present invention is mainly become with pneumatic groups of motors by water pump.Water pump mainly is made up of end cap 1, impeller 2 and the pump housing 3.Pneumatic motor mainly is made up of housing 5, blade 6, rotor 7, stator 8, distribution end cap 9, throttle valve 10 and regulating handle 12.4 blades 6 are contained in the axial groove of rotor 7, and can slide in groove.Rotor 7 is packed in the stator 8 prejudicially, and connects with housing 5 and distribution end cap 9 by bearings at both ends 14.On distribution end cap 9, air inlet/outlet is arranged.Throttle valve 10 is housed on the suction port of end cap 9.Handle 12 on the rotating valve 10 can change the size of throttle valve 10 inner flow passage open amounts, can change the air supply that is input in the motor thus, thereby can control the rotating speed of motor rotor 7.Make the water pump vane 2 installed on the rotor 7 rotation speed change and the delivery pressure of water pump and flow are also changed.Motor casing 5 combines as a whole with the pump housing 3 usefulness screws.Impeller 2 in the pump is sleeved on the output shaft of rotor 7 with spline structure.Seal ring 15 can be sealed the axial leakage of current in the pump.The structure of the water intake of end cap 1 can connect fast with the fire-extinguisher water hose of standard.Structure at the water outlet place of the pump housing 3 can connect with the import of quick tieing 11 with the fire-fighting lance 13 of standard.The top of the pump housing 3 has carrying handle 4 to carry for the fire personnel.Also can articulate so that the fire personnel takes on the antiform formula carries with the shoulder belt ring on shoulder belt and the hydraulic giant 13.For weight reduction, end cap 1, the pump housing 3, impeller 2, housing 5 and distribution end cap 9 have adopted the material of the light weight resemble the aluminum alloy for example to make.
