Abstract
The utility model discloses a kind of tunnel ventilation road guide-rings, belong to tunnel ventilation technical field.It includes one group of arc shaped blade, horizontal support, vertical supports, setscrew, the arc shaped blade is equidistantly located at tunnel air duct turning, both ends and middle part and the horizontal support of arc shaped blade are fixed, horizontal support both ends are fixed with vertical supports respectively, and vertical supports are fixed by setscrew and tunnel air duct wall.Airflow path equilibrium is streamlined by one group of arc shaped blade of guide-ring, by tunnel air duct turning because air-flow caused by the deflecting of air duct is unevenly mutated and is vortexed thorough elimination, and do not generate trailing vortex, the increase of resistance caused by vortex and energy loss are avoided completely, greatly improve ventilation system efficiency.
Description
Technical field
The utility model relates to a kind of tunnel ventilation road guide-rings, belong to tunnel ventilation technical field.
Background technique
Oral sex that the air duct of Tunnel Ventilation System and vertical shaft or inclined shaft cross turning and supply air duct and main tunnel are blown
Remittance turning, can generate huge vortex in air-flow operational process, increase ventilating system resistance, lead to supply air system or air draft
System static pressure loss is excessive, and cannot be guaranteed permanent ventilation of tunnel system worked well.Currently, in order to reduce because in air duct whirlpool
The raw influence and influence normal operation ventilation to ventilating system static pressure of miscarriage, can only increase the installation quantity of large axial flow fan
Or installed capacity, so that civil engineering costs and equipment initial outlay be made to increase.Therefore a kind of tunnel ventilation road guide-ring is designed, it
The turbine that ventilating system air duct and vertical shaft or inclined shaft intersection can be effectively prevented from generates, and avoids supply air duct and main tunnel
Air outlet intersection vortex generates, and realizes energy-saving effect, saves ventilating system investment, reduces project cost.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of tunnel ventilation road guide-rings, it is solved
Tunnel air duct turning is easy to produce huge vortex at present, increases ventilating system resistance, leads to supply air system or exhaust system
The excessive problem of hydrostatic pressures losses.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of tunnel ventilation road guide-ring, it includes one group of arc shaped blade, horizontal support, vertical supports, setscrew,
The arc shaped blade is equidistantly located at tunnel air duct turning, and both ends and middle part and the horizontal support of arc shaped blade are fixed, laterally
Bracket both ends are fixed with vertical supports respectively, and vertical supports are fixed by setscrew and tunnel air duct wall.
As preferred embodiment, the arc shaped blade is made by stainless steel thin slice.
As preferred embodiment, the arc shaped blade is by middle part circular arc flow deflector, and is connected to circular arc flow deflector both ends
Plane flow deflector is integrally formed.
The beneficial effects of the utility model are: one group of arc shaped blade of guide-ring by airflow path equilibrium be it is streamlined,
By tunnel air duct turning because air-flow caused by the deflecting of air duct is unevenly mutated and is vortexed thorough elimination, and do not generate tail
Whirlpool avoids the increase of resistance caused by vortex and energy loss completely, greatly improves ventilation system efficiency；The arc of spaced set
Air-flow is divided into multiple smooth airflow layers by blade, increases effective contact area of air-flow and rigid plane, and tunnel air duct turns
Crook air loss is smaller；It is fixed using vertical supports and tunnel air duct wall, is only equipped with cross at arc shaped blade both ends and middle part
It to bracket, can either prevent circular arc from deforming, and resistance can be minimized；Arc shaped blade by middle part circular arc flow deflector, and
The plane flow deflector for being connected to circular arc flow deflector both ends is integrally formed, and plane flow deflector can uniformly divide air-flow in the same direction in advance
It cuts, delays release in the same direction and converge, flowed energy loss is smaller, and vortex is effectively prevent to generate.
Detailed description of the invention
Fig. 1 is the overlooking structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of tunnel air duct cross section；
Fig. 3 is the overlooking structure diagram of arc shaped blade.
In figure: arc shaped blade 1, horizontal support 2, vertical supports 3, setscrew 4, tunnel air duct 5, circular arc flow deflector 11,
Plane flow deflector 12.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below
Conjunction is specifically illustrating, and the utility model is further described.
As shown in Figure 1-Figure 3, a kind of tunnel ventilation road guide-ring, it includes one group of arc shaped blade 1, horizontal support 2, erects
To bracket 3, setscrew 4, arc shaped blade 1 is equidistantly located at 5 turning of tunnel air duct, the both ends and middle part of arc shaped blade 1 with
Horizontal support 2 is fixed, and 2 both ends of horizontal support are fixed with vertical supports 3 respectively, and vertical supports 3 pass through setscrew 4 and tunnel wind
5 wall of road is fixed.
Arc shaped blade 1 is made by stainless steel thin slice.
Arc shaped blade 1 is by middle part circular arc flow deflector 11, and is connected to the plane flow deflector 12 at 11 both ends of circular arc flow deflector
It is integrally formed.
One group of arc shaped blade 1 of guide-ring by airflow path equilibrium be it is streamlined, by 5 turning of tunnel air duct because of wind
Air-flow caused by road deflecting is unevenly mutated and is vortexed thorough elimination, and does not generate trailing vortex, is avoided caused by vortex completely
Resistance increases and energy loss, greatly improves ventilation system efficiency；Air-flow is divided into multiple by the arc shaped blade 1 of spaced set
Smooth airflow layer, increases effective contact area of air-flow and rigid plane, and 5 turning air loss of tunnel air duct is smaller；It adopts
It is fixed with vertical supports 3 and 5 wall of tunnel air duct, is only equipped with horizontal support 2 at 1 both ends of arc shaped blade and middle part, can either prevent
Only circular arc stress deformation, and resistance can be minimized；Arc shaped blade 1 is by middle part circular arc flow deflector 11, and is connected to circle
The plane flow deflector 12 at 11 both ends of arc flow deflector is integrally formed, and plane flow deflector 12 can shift to an earlier date even partition in the same direction to air-flow,
It delays release in the same direction to converge, flowed energy loss is smaller, and vortex is effectively prevent to generate.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry it should be appreciated that the present utility model is not limited to the above embodiments, do not depart from the spirit of the present invention and
