Description
Technical field
This utility model belongs to engineering element technical field, relates to a kind of firefighting security device,
Particularly relate to a kind of firefighting fan.
Background technology
In various disasters, fire is to threaten public security and society most frequently, the most at large
One of major casualty of development, the personnel died the most in a fire are countless, because
Fire can produce substantial amounts of poison gas, such as CO, CO when occurring2, HCl etc., simultaneously also
Substantial amounts of heat can be discharged and consume substantial amounts of oxygen.According to statistics, in fire fatality number
More than 50% all due to flue gas edifying anoxia cause.Therefore, for the peace of support personnel
Full evacuation beneficially fire-fighting remedial efforts, be typically equipped with Smoke prevention and smoke evacuation in building
Device.Firefighting fan be one can run continuously under 300 DEG C of hot conditionss more than 60 minutes,
Running the industrial fan that 20 hours/time are not damaged under 100 DEG C of temperature conditionss continuously, it can
High temperature air dirty in building directly or is purified heel row extremely outdoor, then fresh sky
Gas supplements into, thus ensures the quality of air environment requirement of indoor, and the one being conventional disappears
Smoke controlling device.
Existing firefighting fan all includes air duct and the motor being arranged in air duct, impeller.Existing
It is poor all to there is radiating effect in some firefighting fans, and motor such as is easily damaged at the problem.As China is special
Profit application (notification number: CN201696348U) discloses a kind of firefighting fan, including air duct
Be arranged in air duct with the actuating device of fluid motor-driven, actuating device axle is connected with torsion
The wind wheel of curved blade, wind wheel is evenly distributed in nine fan blades, and air duct inwall fills with transmission
It is provided with for guiding wind direction and passive stator between putting, the air inlet end of air duct
It is additionally provided with protective cover.This firefighting fan is when getting rid of high-temperature flue gas, and motor is for a long time at height
Working under temperature state and can not get dispelling the heat timely and cooling down, be easily damaged, service life is shorter,
Also can affect the running of whole firefighting fan, it is impossible to get rid of flue gas timely, reduce fire-fighting
The reliability of safety, the vibrations of this equipment are the biggest, the problem causing noise and structural stability.
Utility model content
In place of solving above-mentioned the deficiencies in the prior art, the purpose of this utility model is to carry
A kind of simple in construction of confession, the firefighting fan that stability is strong, to overcome defect of the prior art.
To achieve these goals, this utility model provides a kind of firefighting fan, described in disappear

Being provided with blower fan, the opened above of described square frame front walls has an air outlet, described side
It is installed with adjustable padded base on outside shape frame top, described padded base is provided with
Crash roll, described crash roll is installed with the motor for driving described blower fan to operate, described
The central shaft of motor is connected with the central shaft driven of described blower fan by belt.
Further illustrate as to firefighting fan described in the utility model, it is preferable that institute
Stating blower fan is turbine type blower fan.
Further illustrate as to firefighting fan described in the utility model, it is preferable that institute
State crash roll to be made up of EVA material.
As can be seen here, this utility model provides a kind of firefighting fan, and described firefighting fan includes
Square frame, is provided with inner chamber in described square frame, described inner chamber central authorities are provided with blower fan,
The opened above of described square frame front walls has an air outlet, outside described square frame top
It is installed with adjustable padded base on side, described padded base is provided with crash roll, described
The motor for driving described blower fan to operate, the central shaft of described motor it is installed with on crash roll
It is connected by the central shaft driven of belt with described blower fan.This utility model simple in construction, steady
Qualitative strong, easy for installation, exhaust air rate improves a lot.
Accompanying drawing explanation
Fig. 1 is the structural representation of firefighting fan of the present utility model.
Description of reference numerals is as follows:
