Description
Technical field
The utility model relates to a kind of hand-held Blower extinguishment machine, belongs to spray technical field.
Background technology
Wind-force fire-fighting principle mainly utilizes the kinetic energy of flowing wind-force fast to be taken away by the heat energy in the scene of a fire rapidly, and reduction combustible and comburant temperature reach fire extinguishing order, and therefore nearer effect of wind moment burning things which may cause a fire disaster better.Wind fire-extinguisher is since appearance, and because of the lightweight advantage such as effective of putting out the fire easy to carry, till now always as the most applicable machine tool of putting out the fire, have the duty history of nearly 30 years till now, the success for forest fires is puted out a fire to save life and property and provided important guarantee.In design and use process, have a better effect, but now found deficiency in carrying.Putting out the fire in practice, being an important component part of the work of putting out the fire because facility carry, is also the important stage that staff enters the scene of a fire, and because of road reason, the road that great majority enter the scene of a fire is unsatisfactory and extremely complexity.Fire extinguishing wind speed is than the obvious decline of outlet, and kinetic energy is and square being directly proportional of wind speed, and the wind energy loss really for putting out a fire is a lot, can not make full use of the wind energy of blower fan.
Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of hand-held Blower extinguishment machine.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of hand-held Blower extinguishment machine, comprise blower fan and air duct, air duct comprises leading portion air duct and interlude air duct, connected by telescopic section air duct between leading portion air duct and interlude air duct, it is inner that interlude air duct is located at by blower fan, blower fan by bearing by driven by motor, motor shroud is arranged with outside motor, motor shroud is latticed, be provided with wind-collecting cover between interlude air duct and motor shroud, wind-collecting cover is provided with air inlet, and between interlude air duct and motor shroud, top is provided with shoulder belt, leading portion air duct is provided with switch, and switch connects motor.
The related content of technique scheme is explained as follows:
In technique scheme, shoulder belt is elastic webbing.
Further technical scheme, interlude air duct inner air channel cross section is rectangle, and leading portion air duct inner air channel cross section is circular.
Preferably, leading portion air duct outer surface switch side is provided with hand grip.
Preferably, hand grip is welded on leading portion air duct by base.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Volume is little, is convenient for carrying, lightweight, and be convenient to carrying and vanning, wind energy utilization efficiency is high, good extinguishing effect, vigorously advocates scientific and technical innovation, builds the atmosphere of the harmony work that people-oriented, has certain realistic meaning to the raising of fight productivity of putting out the fire.
