Description
One, technical field
The present invention relates to a kind of smoke exhaust fan, relate in particular to a kind of hydro powered smoke exhaust fan of using, belong to machinery manufacturing technology field, the present invention is mainly used in fire protection sector, result of use highly significant under Duan Dian the situation at the scene, it mainly acts on is that a large amount of smog that cause on fire are blown open, so that the personnel escape in the building is convenient to the fire fighter simultaneously and is entered building and put out a fire, rescue the people, rescue thing.
Two, background technology
As everyone knows, in the time of a building (comprising factory building, freight house, market, hotel, dwelling house etc.) breaking out of fire, will produce a large amount of dense smoke, personnel flee from these smog serious disturbance buildings, disturb the fire fighter to rescue the people, rescue thing; Disturb firefighters to enter building fire extinguishing or the like.So these smog must be arranged, these smog are best, also the most direct way dispels it exactly and arranges and arrange, this just needs to use powerful blower fan.Generally speaking, all power supplys will be cut off when building is on fire, and for safety can not be used general generator for electricity generation, therefore, the blower fan that common electric machine drives can't use.In order to address this problem, the fire-fighting equipment production firm of countries in the world, all at the novel smoke exhaust fan drive unit of research, and after the blower fan of hydro powered came across 2000 in the world, but there is following shortcoming in present this blower fan:
1. hydroturbine does not have spiral case, and hydraulic efficiency is very low, and has only 1 nozzle;
2. the current of hydroturbine flash, and be not easy to move, and the fire fighter can't be close;
3. water can not reclaim, and causes the very big waste of fire demand water.
Three, summary of the invention
Purpose of the present invention is exactly in order to improve the hydraulic efficiency of existing hydro powered blower fan; Be not easy to move when solving use, current flash; Fire water can not be reclaimed after using, and causes very big problems such as the fire water wasting of resources, thereby a kind of new technical scheme is provided.
For achieving the above object, the present invention can be achieved through the following technical solutions:
The current that provide with fire fighting truck or fire hydrant are power, have designed spiral case (procapsid and back casing form after being tightly connected), turbine room (procapsid and back casing form after being tightly connected), turbine, nozzle, water inlet pipe, outlet pipe, power transmission shaft, high-power fan etc.
Concrete design is:
The hydro powered smoke exhaust fan, include open type turbine, power transmission shaft and high-power fan, outside the open type turbine, place and be provided with the enclosed shape shell of forming by procapsid and back casing, the shape of back casing is a concave structure, back casing is provided with and becomes the oval vortex street of section, forms spiral case and turbine room after back casing and procapsid are tightly connected; Be welded with 2～5 nozzles on the inwall of procapsid, its nozzle-axis and turbine distribution circle are tangent; Water inlet pipe and outlet pipe are housed on the back casing simultaneously, and buckle is equipped with in water inlet pipe and outlet pipe termination; Turbine wheel shaft links to each other with fan shaft is coaxial, by two bearings.
Back casing is provided with and becomes the semicircle vortex street of section, and vortex street forms spiral case and turbine room after by procapsid and back casing fixed seal connection; Be welded with 3 nozzles on the inwall of procapsid, the angle between nozzle and the nozzle is 75-90 °.
Advantage of the present invention is: simple in structure, use and conveniently moving the hydraulic efficiency height; Simultaneously, current repeated use capable of circulation can be saved a large amount of fire demand waters; The hydraulic pressure that utilizes fire fighting truck or fire hydrant etc. to provide is power, utilizes turbine to replace the Motor Drive blower fan to rotate, and reaches normal rotation speed of fan and wind-force; Dispel a large amount of dense smokes that the scene of catching fire (factory building, freight house, market, hotel, dwelling house) is produced with this, so that personnel escape in the building is convenient to the fire fighter simultaneously and is entered the building fire extinguishing, rescues the people, rescues thing; Adopt hydro powered, overcome on-the-spot outage on fire and can not use motor and the predicament that can not use common blower fan.
The volute and the turbine room that have formed after the present invention has adopted procapsid and back casing to be tightly connected in design, and the procapsid inwall is provided with a plurality of nozzles, so not only can improve the hydraulic efficiency of turbine greatly, and the fire fighter is carried at any time, it is moved to the position that needs, improved the result of use of blower fan greatly and rescue the people, rescue the success rate of thing.Simultaneously, back casing is provided with water inlet pipe and is connected with outlet pipe and with the water source that has certain pressure, and the current that fire fighting truck is provided can be reused, and have saved fire demand water greatly, and improving water can service efficiency.
Four, description of drawings
Accompanying drawing 1 is a kind of exemplary construction schematic diagram of the present invention, be in the accompanying drawing 2 B-B to the revolved section schematic diagram;
Accompanying drawing 2 is that the A-A of accompanying drawing 1 of the present invention is to the structure cross-sectional schematic.
Among the figure: 1-water inlet pipe, 2-back casing, 3-volute, 4-procapsid, 5-turbine, 6-high-power fan, 7-bearing, 8-power transmission shaft, 9-turbine room, 10-outlet pipe, 11-nozzle
