Description
Technical field
The utility model relates to a kind of packaged type fire-fighting air-supply fume extractors, belong to technical field of fire control.
Background technique
Statistics shows that in fire 70%~75% personnel death is sucked caused by volume of smoke and toxic and harmful gas, can
See that fire smoke is big to the harm of people, is advised according to the correlation of " public security fire-fighting army combat regulation on duty " chapter 1 Article 4
Fixed, smoke evacuation should be the action carried out at the first time after fire brigade shows up, and smoke extraction is fire brigade at important of the scene of a fire
One of business.In order to increase the survival probability of trapped person, the fire fighting and rescue ability of fire brigade is improved, smoke extraction should be reinforced,
Research and development can fast and efficiently blow fume extractor in fire-fighting, carry out sufficient preparation for rescue work.
Utility model content
In order to solve problem above, the utility model provides a kind of packaged type fire-fighting air-supply fume extractor.
The utility model is realized in this way: a kind of packaged type fire-fighting is blown fume extractor, including ventilation blower and is started
Machine, bracket, the ventilation blower and engine are each provided on bracket, and the ventilation blower includes air entry, impeller front disc, leaf
Piece, impeller hub disk, casing, exhaust outlet and intercepter plate, the cabinet sides are equipped with exhaust outlet, are provided with and shut off below exhaust outlet
Plate, the air entry are arranged on the wall of casing circular cross section, and impeller front disc, blade and impeller hub disk are set after being sequentially connected
In the centre bore of casing, the bracket is additionally provided with movable pulley.
Preferably, the movable pulley of the bracket is universal wheel.
Preferably, the engine is diesel engine.
Preferably, the ventilation blower is forced draft smoke evacuation.
Preferably, the ventilation blower is additionally provided with diffuser, and the diffuser is arranged in exhaust outlet port position.
The beneficial effects of the utility model are: solving traditional fire-fighting air-supply fume extractor can not spirit by the utility model
Mobile disadvantage living, can fast and efficiently discharge flue gas whenever necessary, save manpower, time for fire-fighting work,
Fireman is allowed quickly to enter in fire-fighting and rescue work.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of packaged type fire-fighting air-supply fume extractor of the utility model；
Fig. 2 is the structural schematic diagram of the utility model ventilation blower；
Fig. 3 is the structural schematic diagram of the utility model smoke evacuation state；
In figure: 1. ventilation blowers, 2. engines, 3. brackets, 101. air entries, 102. impeller front discs, 103. blades, 104. leaves
Take turns hub disk, 105. casings, 106. exhaust outlets, 107. intercepter plates, 108. diffusers.
Specific embodiment
It is further to the utility model with reference to the accompanying drawing in order to be more clearly understood that the technical solution of the utility model
Explanation.
A kind of packaged type fire-fighting air-supply fume extractor as Figure 1-Figure 2, including ventilation blower 1 and engine 2, bracket
3, the ventilation blower 1 and engine 2 are each provided on bracket, the ventilation blower 1 include air entry 101, impeller front disc 102,
Blade 103, impeller hub disk 104, casing 105, exhaust outlet 106 and intercepter plate 107,105 side of casing are equipped with exhaust outlet
106, intercepter plate 107 is provided with below exhaust outlet 106, and the wall of 105 circular cross section of casing is arranged in the air entry 101
On, impeller front disc 102, blade 103 and impeller hub disk 104 are located at the centre bore of casing 105, the bracket 3 after being sequentially connected
It is additionally provided with movable pulley.
The movable pulley of the bracket 3 is universal wheel.
The engine 2 is diesel engine.
The ventilation blower 1 is forced draft smoke evacuation.
The ventilation blower 1 is additionally provided with diffuser 108, and the diffuser 108 is arranged in 106 port position of exhaust outlet.
Fume extractor quickly can be moved to air outlet and goes out by fireman when having fire, and used engine is diesel oil hair
Motivation is not necessarily to plug-in, does not limit fume extractor placement location, saves the time and can adjust in optimum position, fume extractor work
When, driven by engine blade rotation, air enters from air entry, is discharged from exhaust outlet, positive pressure is formed, while increasing diffuser,
It carries out smoke evacuation work preferably, sufficient preparation is carried out for fire-fighting and rescue, as shown in figure 3, when implementing forced draft smoke evacuation,
Fireman does not have to be deep into building interior, induced-draft fan only need to be arranged at the passway in building or room, this makes fireman not
High temperature must be exposed to, in toxic flue gas environment, reduce the risk of fire fighting and rescue action to a certain extent；Compared to negative
Pressure type induced-draft fan is not had to setting smoke discharging pipe when being discharged fume using forced draft, reduces the obstruction to rescue channel, is fire-fighting
Equipment is attacked and transported in member's entrance building implementation provide space；Compared to other kinds of smoke exhaust method, forced draft smoke evacuation
The high temperature poison gas of building interior can more effectively be discharged, provide preferably protection and rescue ring so as to attack personnel in
Border, and can preferably protect the article of building interior.When discharging fume using forced draft, induced-draft fan is only needed to be sent into sky into building
The high temperature poison gas of gas, building interior will not be by induced-draft fan, thus reduces the work of induced-draft fan cleaning and maintenance
Amount, and the service life of induced-draft fan can be improved.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
