Abstract
The utility model relates to a fume extractor which belongs to fire fighting devices. The utility model is composed of a trolley, a gasoline engine, an outer cover, a helical impeller, an air duct, etc., wherein, the helical impeller is driven by a main shaft of the gasoline engine to rotate at high speed, which causes air around the helical impeller to flow at high speed. So the helical impeller can blow off smog or causes the smog to be sucked into the outer cover and be exhausted by the air duct. The fume extractor has the advantages of high flexibility and portability, is especially suitable for extracting and bellowing smoke, or extinguishing fire at various fire extinguishing locales, and is suitable for being used and configured by each fire brigade.
Description
The utility model is a kind of induced-draft fan, belongs to the fire-fighting equipment equipment.
On-the-spot in real-life fire fighting, often with a large amount of smog, visibility is extremely low.The smog in the scene of a fire not only can make the fire fighter be difficult to distinguish burning things which may cause a fire disaster, brings difficulty for work such as putting out a fire, rescue the people rapidly, and can make the fire fighter be difficult to stand, and also can cause rescuing and being rescued by rifle personnel's death by suffocation when serious.At the after-stage that rifle is rescued, also the utmost point needs rapid venting smog, so that check exhaustively latent fire is arranged.
But before the utility model was made, domestic fire-fighting system had not been seen the smoke evacuation equipment as yet.Rely on that the people dresses gas mask or protective garment tackles smog in that fire fighting is on-the-spot main, thereby except bringing many inconvenience to fire fighting, and the efficient of fire fighting also is under some influence.Dispersing scene of a fire smog at present mostly still is in and allows its natural diffusion phase.
There had a kind of smoke evacuation automobile to be used for fire fighting abroad to be on-the-spot, but the upper strata of place that can not arrive automobile and skyscraper is still powerless, and its scope of application is limited, and this smoke evacuation vehicle price costliness, and general fire brigade can not dispose.
In view of the foregoing, the utility model has solved the on-the-spot fiery mist problem that puts forward of fire fighting.Can assist fire extinguishing again for the scene of putting out a fire provides a kind of smog of can getting rid of, and be applicable to the on-the-spot induced-draft fan of various fire fightings.
The utility model is made up of dolly, gasoline engine, outer cover, helical runner, guide duct.Wherein dolly adopts a kind of portable steel-tube construction, and a pair roller is equipped with in the bottom, and it is designed to push away, can lifts, Knapsack, and its effect is as the installation of induced-draft fan and carries the basis; Gasoline engine is 5 general horse power petrol engines, and characteristics are mobility strongs, and as the power source of induced-draft fan, it is fixedly mounted on the dolly with outer cover; For ease of making and being connected guide duct, outer cover is designed to common cylindric, and is provided with the extinguishing chemical spout in the cylindrical shell front end face and is connected groove or fin with guide duct; Guide duct is the flexible long-channel made from material, and the flexibility of its passage makes it also can outwards lead cigarette smoothly having under the occasion at turning, and effect is that guiding smog spreads outside the scene of a fire; Helical runner is fixed on the gasoline engine main shaft, its blade is made up of two or several pieces, the helical geometry of blade guarantees that according to the design of air power source principle the helical runner ambient air will be subjected to pneumatic action and flow at high speed when it rotates with gasoline engine main shaft one superhigh speed.
Characteristics of the present utility model are, and are simple in structure, light and handy flexibly, easy to use, are applicable to the on-the-spot smokings of various fire fightings, blow cigarette or fire extinguishing operation, and suitable each fire brigade's configuration is used.
Fig. 1 is a structural representation of the present utility model, (1) dolly, (2) gasoline engine, (3) outer cover, (4) helical runner, (5) extinguishing chemical spout, (6) guide duct connection groove or fin, (7) guide duct.
Fig. 2 is a smoke view of the present utility model.
Fig. 3 is cigarette or the fire extinguishing user mode schematic diagram of blowing of the present utility model.
During work, induced-draft fan is pushed the smog scene, air guide hole is back to the smog field, start gasoline engine, drive helical runner during the gasoline engine spindle operation and rotate together, the smog around the effect down smoke-discharging machine of helical runner is sucked into outer cover, is drawn out to outside the scene of a fire by guide duct. Remove guide duct, connect the extinguishing chemical path, targeting port is towards the scene of a fire, and the high speed fire extinguishing air-flow that relies on helical runner to be discharged blows, sweeps the scene of a fire, then can work dispelling smog and fire extinguishing function, this induced-draft fan also may be used on the aspect smoke evacuations such as mining site, tunnel, air blast, ventilation blower use.
