Description
Technical field
The utility model is related to a kind of building Tunnel Ventilation System.
Background technology
Apply at present building tunnel in pressure pipeline blower fan on often only have one group of fan blade, cause blast compared with
Low, in addition, the pressure pipeline is typically not easy to remove, cause to clean and keep in repair inconvenience；In addition, noise is also larger after air-out.
Utility model content
The purpose of this utility model is to provide a kind of building Tunnel Ventilation System, solves how to improve its air output and make which
Easily disassembled while reducing the technical problem of its wind noise.
Building Tunnel Ventilation System, including fixed seat, air intake part, transition piece, blower fan, air-out part；Air intake part and air-out part
It is fixed in fixed seat, blower fan is fixed on inside transition piece；Air intake part and air-out part are horn-like and being arranged in this
Cross part both sides；Transition piece is included with cylindrical element jaggy, hand pressure bar, connection sheet；Hand pressure bar camber, its one end are hinged on circle
One end of the breach of barrier part, intermediate ends are hinged with one end of connection sheet；Connection sheet is arc, the other end and cylindrical element of connection sheet
The other end of breach be hinged；The wind wheel includes the wheel hub of taper, multiple blades, multiple auxiliary leaves；Leaf positional distribution on wheel hub,
Auxiliary leaf is fixed between the middle and lower part on wheel hub and in each two adjacent blades；The rear end of the motor has a hemispherical
Kuppe.
The beneficial effects of the utility model are：As transition piece realizes the closure of breach using hand pressure bar and connection sheet and opens
Open, so convenient to being cleaned and being keeped in repair inside transition piece；Due to being mounted with that on wheel hub auxiliary leaf, auxiliary leaf are done to air
Work(, so as to reduce the vortex between adjacent blades, auxiliary leaf is more, and vortex is less, and fan blade is also higher；Due in motor rear end
A hemispheric kuppe is increased, so reduces the noise of wind flow.

Specific embodiment
Fig. 1 to Fig. 5 is refer to, the building Tunnel Ventilation System in figure, including 1, air intake part 2, of a fixed seat
4, one, the motor kuppe 7 of air-out part 6, of wind wheel 5, of individual transition piece 3,.
Air intake part 2 and air-out part 6 are generally horn-like, and its bottom has two legs 21, and the two insertions of leg 21 are solid
Fix in reservation 1 and using bolt, air intake part 2 and air-out part 6 are horn-like and are arranged in 3 both sides of transition piece to this.
Transition piece 3 includes 32, one, a hand pressure bar connection sheet 33 of the cylindrical element with jagged 311 31,.Cylindrical element
31 is generally cylindric, and which has a breach 311.32 overall camber of hand pressure bar, its one end are hinged on lacking for cylindrical element 31
One end of mouth 311, intermediate ends are hinged with one end of connection sheet 33.The generally arc of connection sheet 33, the other end of connection sheet 33 with
The other end of the breach 311 of cylindrical element 31 is hinged.Connection sheet 33 and cylinder are so just driven when hand pressure bar 32 is pressed down
Part 31 moves the closure for realizing 31 breach 311 of cylindrical element together, just drives 33 He of connection sheet when hand pressure bar 32 is started upward
Cylindrical element 31 moves the unlatching for realizing 31 breach 311 of cylindrical element together.The breach 311 of cylindrical element 31 open just convenient maintenance and
Cleaning of.
Wind wheel 5 includes the wheel hub 51 of taper, multiple blades 52, multiple auxiliary leaves 53；Blade 52 is evenly distributed in wheel hub 51
On, what auxiliary leaf 54 was inclined is fixed between the middle and lower part on wheel hub 51 and in each two adjacent blades 52；So pass through leaf 52
Piece and the common operational of auxiliary leaf 53, realize the effect of supercharging.
The rear end of motor 4 has a hemispheric kuppe 7, and the wind for flowing out is oriented to.
