Abstract
The utility model discloses a pneumatic extinguisher which comprises a motor and a conical wind tube and is characterized in that the motor is connected with a flow mixing impeller in a driving way, the flow mixing impeller is arranged in the conical wind tube and a wind inlet hood is arranged at the large end of the conical wind tube; guide vanes are arranged in the conical wind tube and are arranged between the flow mixing impeller and the small end of the conical wind tube and at a position close to the flow mixing impeller; and a shoulder frame is arranged on the shell of the motor. Since a centrifugal fan is changed into the flow mixing impeller which is higher in efficiency, the wind flow is large, the efficiency is high and the like; since higher outlet wind speed can be obtained by using the outlet throat of the conical wind tube which is larger than the wind outlet of a centrifugal pneumatic extinguisher, the effective fire extinguishing range of the pneumatic extinguisher can be greatly improved; and moreover, the portability is high.
Description
Technical field
The utility model relates to a kind of mountain forest extinguishing device of pocket, relates to a kind of wind fire-extinguisher of pocket specifically.
Background technology
Wind fire-extinguisher in the market is a Small Centrifugal Fan that is driven by motor normally, the air outlet of Small Centrifugal Fan is connected with outlet convergence shape air duct, the air-flow that produces during Small Centrifugal Fan work is after the acceleration of outlet convergence shape air duct, the air outlet of air duct can obtain higher dynamic pressure, reach the effect of fire extinguishing with this, often be applied to man portable mountain forest fire extinguishing, motor is miniature gasoline engine or diesel engine usually.Because the characteristic of centrifugal blower has determined this wind fire-extinguisher to exist little, the inefficient limitation of air quantity, spray outlet nozzle size is generally less, the maximum outlet of spray wind speed can only be about 30m/s, therefore effectively the fire extinguishing scope is less, as will further improving effective fire extinguishing scope, just require the centrifugal blower of more powerful motor and bigger model, can increase complete machine size and weight, reduced the portability of equipment energy.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind ofly can have higher air quantity and outlet wind speed, has portable wind fire-extinguisher again.
For achieving the above object, the technical solution adopted in the utility model is: a kind of wind fire-extinguisher, comprise motor and taper air duct, and described motor drives and is connected with mixed flow impeller, described mixed flow impeller places in the taper air duct, and the big end of described taper air duct has air intake cover.
Also be provided with stator in the described taper air duct, described stator places between the small end of mixed flow impeller and taper air duct near the mixed flow impeller place.
Also be provided with the shoulder frame on the shell of described motor.
Adopted wind fire-extinguisher of the present utility model, because centrifugal blower is changed into the higher mixed flow impeller of efficient, it is big to have air quantity, the efficient advantages of higher, can adopt the bigger taper air duct outlet throat dimension of ratio centrifugal wind fire-extinguisher and obtain bigger outlet wind speed, can improve effective fire extinguishing scope of wind fire-extinguisher greatly.Simultaneously, portable performance is preferably also arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a perspective view of the present utility model.
Among the figure: the 1-motor, 2-taper air duct, the 3-mixed flow impeller, the 4-air intake cover, the 5-stator, 6-takes on frame, and 7-hands frame.
The specific embodiment
As depicted in figs. 1 and 2, the utility model discloses a kind of wind fire-extinguisher, comprise motor 1 and taper air duct 2, described motor 1 can adopt small-sized petrol engine or Diesel engine usually, the big end of described taper air duct 2 is near motor 1, the small end of described taper air duct 2 is the air outlet of wind fire-extinguisher, is used to aim at the scene of a fire operation of putting out a fire during use.The fire fighter also need be provided with hand-held frame 7 at wind fire-extinguisher usually to the operation of wind fire-extinguisher for convenience, and during concrete operations, the fire fighter is held on the hand-held frame 7 with holding.In sum, with existing wind fire-extinguisher basically identical.
Innovative point of the present utility model mainly drives in described motor 1 and is connected with mixed flow impeller 3, and described mixed flow impeller 3 places in the taper air duct 2, and the big end of described taper air duct 2 has air intake cover 4.When motor 1 running, motor 1 drives mixed flow impeller 3 high speed rotations and produces high pressure draught small end ejection from taper air duct 2 after the acceleration of taper air duct 2, simultaneously, when rotating at a high speed, mixed flow impeller 3 produces negative pressure at its rear portion, under the effect of negative pressure, extraneous air-flow is inhaled into mixed flow impeller 3 places through air intake cover 4.
In order further to improve the efficient of wind fire-extinguisher of the present utility model, also be provided with stator 5 in the described taper air duct 2, described stator 5 places close mixed flow impeller 3 places between the small end of mixed flow impeller 3 and taper air duct 2.Under the guiding of stator 5, the air-flow that quickens through mixed flow impeller 3 is directed having avoided the decrease in efficiency that causes because of sinuous flow to same direction.
For convenience, also be provided with shoulder frame 6 on the shell of the motor 1 of wind fire-extinguisher of the present utility model to the carrying of wind fire-extinguisher.The fire fighter can utilize shoulder frame 6 that wind fire-extinguisher is hung on the both shoulders, simultaneously, when putting out a fire operation, utilizes shoulder frame 6 that wind fire-extinguisher is hung on the both shoulders, can alleviate exerting oneself of arm greatly, reduces fire fighter's arm fatigue.
