Description
Technical field: the present invention relates to wind fire-extinguisher, specifically double-faced ventilated formula efficient double-wheel wind fire-extinguisher.
, for the Portable pneumatic extinguisher of extinguishing forest fire, in use, there are 4 deficiencies: one is single side air inlet, and intake is few, and air duct mouth diameter is little in background technology: at present, causes that air output is few, wind speed is low; Two is that petrol engine cooling effect is poor, and the power that works long hours declines to some extent, affects fire-fighting efficiency; Three is the waste gas that engine is discharged, and scatters and disappears in atmosphere and apart from operator too closely, causes air and aspiration contamination; Four is that wind fire-extinguisher complete machine lays particular stress on that to make to carry inconvenience, labour intensity large etc.
Summary of the invention: the object of the invention is, design that a kind of import and export air quantity is large, wind speed is high, complete machine is lightweight, good cooling results, high engine speeds are long for the duration of runs for forest puts out the fire, and the waste gas that engine cooling itself air-flow and blast pipe are discharged all is drawn back into by the Fan casing of the forward and backward plate of casing, the integrally welded centrifugal spiral case of side plate three editions, oxygen concentration in desalination casing, is formed containing nitrogen dioxide (CO
2), steam (H
2o), nitrogen (N
2) etc. the chemical fumes favourable to fire extinguishing cooling, density is larger than air again and heavy, and inertia is also large, and merging into the powerful air-flow that can improve range discharges through air duct, is directly used in the double-faced ventilated formula efficient double-wheel wind fire-extinguisher of fire extinguishing.Its main technical content is, double-faced ventilated formula efficient double-wheel wind fire-extinguisher, by an air-cooled two-stroke gasoline engine, double-faced ventilated formula double-vane fan, air duct, end cap, air intake cover, forward and backward hand etc. form; It is characterized in that, plate after fixing casing on the engine, offer the rear air inlet corresponding with cylinder, crankcase, blast pipe position; Forward-curved blade double-faced ventilated impeller is installed in Fan casing; Bilobed wheel is fixed on engine to export on main shaft; Be provided with a short snail tongue in inclined-plane in Fan casing air outlet, after casing, plate has strip air inlet herein, corresponding with cylinder head; Fan casing air outlet has four screws to be connected with the air duct that detachable fountain head is housed, and Fan casing is provided with the end cap and forward and backward operator handle and braces of being with air intake cover.The present invention's advanced part is compared to the prior art: double-faced ventilated formula efficient double-wheel wind fire-extinguisher, have into, air-out flow is large, axial force itself balances and vibrates little, the supercharging of double-faced ventilated interflow, increase wind-force, while intake and exhaust air rate, also cool engine, in short snail tongue design not only air draught cool cylinder, enhance engine cool effect, service life extends, make volute outlet area (Fc) be greater than spiral case equivalent divergent area (Fk) simultaneously, the part in output gas flow dynamic pressure is made to change useful static pressure into, improve the efficiency of spray blower fan, spray air duct air outlet diameter is made to increase by 1/3rd, make that wind speed is per second improves several meters more in the past, also take down the cooling spiral case on crankcase, make Fan casing, crankcase appearance and size reduces, whole spray volume reduces, impeller, crankcase also adopts magnadure, the light metal materials such as air duct, Fan casing sheet iron, so wind fire-extinguisher complete machine weight reduces about one kilogram, engine speed is per minute also improves about 300 turns, spray wind speed air quantity increases, reaction force also increases, body weight when alleviating dynamic, and when spray is operated, more Portable power saving is flexible, thus improve the advantages such as the efficiency of fire extinguishing, and overcome the many deficiencies existing for existing wind fire-extinguisher.
Accompanying drawing illustrates:
Fig. 1 is outward appearance of the present invention main TV structure schematic diagram and air duct 2, cylinder rear air inlet 5, short snail tongue 7, exhaust outlet 9, double-faced ventilated impeller 16 partial schematic sectional view;
Fig. 2 be Fig. 1 Fan casing 3 air outlet A of the present invention to: double-faced ventilated impeller 16, volute outlet area (Fc) 21, spiral case equivalent divergent area (Fk) 22 structural representation and rear air inlet 10, cylinder rear air inlet 5, short snail tongue 7, casing forward and backward plate 24,14 side plate 23 3 plate are welded into the partial schematic sectional view of Fan casing 3;
Fig. 3 is outward appearance plan structure schematic diagram of the present invention and air duct 2, plate 14 side plate 23 case front 24 3 plate is welded into after magneto flywheel 12, casing Fan casing 3, double-entry impeller 16, end cap 18 cross-sectional view;
Wherein, the Fan casing 3 that after fountain head 1, air duct 2 and casing, plate 14, side plate 23, case front 24 3 plate are welded into one, cylinder 4, cylinder rear air inlet 5, blast pipe 6, short snail tongue 7, remote holder be plate 14, petrol engine 15, double-faced ventilated impeller 16, air intake cover 17, end cap 18, rear-handle 19, braces 20, volute outlet area (Fc) 21, spiral case equivalent divergent area (Fk) 22, side plate 23, case front 24 8, after exhaust outlet 9, rear air inlet 10, crankcase 11, magneto flywheel 12, starter 13, casing.
Detailed description of the invention: be further described again below in conjunction with Fig. 1-3 couples of the present invention, after petrol engine 15 and casing, Fan casing 3 is fixed on engine crankcase 11 by plate 14 3 screws; Direct and the double-faced ventilated impeller 16 of magneto flywheel 12 6 screws are connected, and are contained in Fan casing 3, and are close to engine 15 main shaft; The blade of double-faced ventilated impeller 16 adopts aerofoil profile forward-curved blade.After the casing of Fan casing 3, plate 14 has rear air inlet 10, engine 15 air draught is cooled, and by waste gas that blast pipe 6 is discharged, suck in Fan casing 3 by exhaust outlet 9, spray through air duct 2, air duct 2 and Fan casing 3 four screws are connected, and detachable fountain head 1 is installed at air duct 2 air outlet place, joins water loading bag device and can spray wind mist fire-fighting.In Fan casing 3 air outlet, point is welded with the short snail tongue 7 of an iron leg intracutaneous that outlet diffusion angle of flare is 12 ° of inclined-planes, after casing under this angle on plate 14, the cylinder rear air inlet 5 having strip specially carries out air draught cooling to cylinder 4, makes volute outlet area (Fc) 21 be greater than spiral case equivalent divergent area (Fk) 22 simultaneously.Outside Fan casing 3, be provided with air intake cover 17, end cap 18 and front rear-handle 8,19 and braces 20.
During use, first starter 13 is pulled, magneto flywheel 12 is rotated in cylinder 4 and produces high-tension ignition, petrol engine 15 starts to run well, magneto flywheel 12 drives double-faced ventilated impeller 16 to rotate up to per minute 7000, makes to produce mixed at high speed air-flow in Fan casing 3 and is sprayed by air duct 2.When putting out a fire to save life and property the earth's surface such as forest, grassland fire, carry on the arm piggyback by braces 20, operator two hand is held respectively and is arranged on remote holder on Fan casing 38 and rear-handle 19, makes air duct 2 aim at comburant and directly suddenly blows, can put out a fire rapidly, just forms the present invention above.
