The utility model provides a kind of engine turbine guide duct, is related to a kind of engine turbine device.It solves the problems, such as that the vibration of turbine guide duct is big in the prior art, noise is big.This engine turbine guide duct, the tube body including guide duct are provided with guide vane in the guide duct, and guide vane is uniformly distributed in guide duct inner circumferential, and guide vane is towards identical as flow direction of the air-flow in guide duct.Vibration and noise caused by air-flow is effectively reduced using the damped noise reduction device of setting in the utility model, and structure is simple, easy to operate, at low cost.
Description
Technical field
The utility model belongs to technical field of automobile engine, is related to a kind of engine turbine device, especially a kind of hair
Motivation turbine guide duct.
Background technique
Engine turbine provides enough air using the exhaust gas-driven turbine being discharged using engine for engine combustion,
But since the fluctuation for discharging into gas of engine is more violent, cause that vibration is big, noise is big.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, to propose a kind of engine turbine wind-guiding
Pipe, this engine turbine guide duct can be effectively reduced vibration and noise caused by air-flow.
The purpose of this utility model can be realized by the following technical scheme: a kind of engine turbine guide duct, including lead
The tube body of air hose is provided with guide vane in the guide duct, and guide vane is uniformly distributed in guide duct inner circumferential, guide vane direction
It is identical as flow direction of the air-flow in guide duct.
Setting guide vane makes high-speed flow and low speed flow part high-speed flow and low speed gas during mixing
Stream is first mixed, to generate the lesser turbulent flow in part or generate the lesser turbulent flow in part inside high-speed flow, is made in this way
Obtaining the energy that high-speed flow and low speed flow are discharged when being sufficiently mixed reduces, and avoids high-speed flow and low speed flow directly mixed
Merging causes strong turbulent flow.
In above-mentioned engine turbine guide duct, the guide vane is arranged in ring body, before the guide vane
The structure for holding small rear end big, so that the turbulence state of air-flow can be smoothly passed over and reduced to air-flow.
In above-mentioned engine turbine guide duct, the bending place of guide duct is arranged in the guide vane, to prevent
The aggravation of turbulent flow.
In above-mentioned engine turbine guide duct, the ring body is rotatably assorted with wind-guiding inside pipe wall, sets in the ring body
Magnet there are two setting, the magnetic pole of two magnet is in the same direction in the circumferential direction of ring body, is provided on the guide duct between two magnet
Electromagnet attracts the magnet in ring body by electromagnet, to control by the pole orientation of the change control electromagnet of electric current
The rotation of ring body, so that the position of guide vane is adjusted, so that guide vane is in the position of most suitable damping noise reduction.
In above-mentioned engine turbine guide duct, the ring body is flexible elastomer material, is provided with annular in ring body
Chamber, feeder control the pressure of annular intracavity gas, the size of ring body are then controlled, to control guide duct breathing area
Size, so that reaching the optimal of air inlet effect according to the size of operating conditions air-flow, not only having met air inflow but also reducing
Shake noise.
In above-mentioned engine turbine guide duct, it is provided with shock sensor on the guide duct, to perceive constantly
The vibrating state of guide duct.
Compared with prior art, this engine turbine guide duct has the advantage that
Vibration and noise caused by air-flow, structure letter is effectively reduced using the damped noise reduction device of setting in the utility model
It is single, it is easy to operate, it is at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one；
Fig. 2 is the schematic diagram of embodiment two；
Fig. 3 is the schematic diagram of embodiment three.
In figure, tube body 1, guide vane 2, shock sensor 3, ring body 4, magnet 5, electromagnet 6, feeder 7.
Specific embodiment
It is specific embodiment of the utility model below, and the technical solution of the utility model is made further in conjunction with attached drawing
Description, but the utility model is not limited to these examples.
Embodiment one
As shown in Figure 1, a kind of engine turbine guide duct, the tube body 1 including guide duct is provided in the guide duct and leads
To blade 2, guide vane is uniformly distributed in guide duct inner circumferential, flow direction phase of the guide vane direction with air-flow in guide duct
Together.Setting guide vane makes high-speed flow with low speed flow, and part high-speed flow and low speed flow during mixing are advanced
Row mixing, to generate the lesser turbulent flow in part or generate the lesser turbulent flow in part inside high-speed flow, so that high speed
The energy that air-flow and low speed flow are discharged when being sufficiently mixed reduces, and high-speed flow is avoided directly to mix and make with low speed flow
At strong turbulent flow.
The guide vane is arranged in ring body, the big structure in the small rear end in the front end of the guide vane, so as to air-flow
It can smoothly pass over and reduce the turbulence state of air-flow.The bending place of guide duct is arranged in the guide vane, with
Just the aggravation of turbulent flow is prevented.Shock sensor 3 is provided on the guide duct, to perceive the vibrating state of guide duct constantly.
Embodiment two
As shown in Fig. 2, the ring body 4 is rotatably assorted with wind-guiding inside pipe wall, and magnet 5 there are two settings in the ring body, two
The magnetic pole of a magnet is in the same direction in the circumferential direction of ring body, is provided with electromagnet 6 on the guide duct between two magnet, passes through electric current
Change control electromagnet pole orientation, attraction or repulsion by high-speed double electromagnet to magnet in ring body, so as to control ring
The rotation of body, so that the position of guide vane is adjusted, so that guide vane is in the position of most suitable damping noise reduction.
Embodiment three
As shown in figure 3, the ring body is flexible elastomer material, annular chamber, 7 control ring of feeder are provided in ring body
The pressure of shape intracavity gas, then controls the size of ring body, so that the size of guide duct breathing area is controlled, so that
