Description
Technical field
The utility model is related to a kind of turbine more particularly to a kind of turbines for preventing back letting out.
Background technology
It is existing fission turbine generally comprise outer kuppe and with interior kuppe, when turbine rotation, turbine center into
Gas port will suck the air of surrounding, and air is by the driving of the first blade, and from turbine under the guiding function of diversion air duct
The air outlet of surrounding is blown out, and faces out air-supply along the inner wall of outer cover.Since outer kuppe is also operating at work, because
This, outer kuppe must be between outer cover there are certain interval, and otherwise the outside wall surface of outer kuppe can rub with outer cover, shadow
Ring the operation of turbine.However, the air inlet air pressure due to turbine is relatively low, the air outlet air pressure along wheel is higher, therefore, air outlet one
The high pressure draught of side will be returned by this gap and let out air inlet side, can weaken the output pressure and flow of turbine in this way,
Influence the performance of turbine.
Utility model content
The purpose of this utility model is to provide a kind of molding mixed flow turbines of fission, have and prevent back letting out, effectively improve and send
The advantages of wind performance.
To achieve the goals above, the molding mixed flow turbine of fission provided by the utility model, including outer kuppe and and
Interior kuppe, the outer kuppe inner wall and between interior water conservancy diversion cover outer wall around the central axis of any one be equipped with several first
Blade, the interior kuppe and the cooperation installation of outer kuppe, first blade, the outer wall of interior kuppe and outer kuppe it is interior
Diversion air duct is formed between wall, surrounding the central axis on the outer wall of the outer kuppe is equipped with several second blades.
Compared with prior art, since the utility model on the outer wall of the outer kuppe by surrounding the central shaft
Several second blades are arranged in line, so as to so that second blade in the gap between the outer kuppe and outer cover,
When the outer kuppe operating, second blade also operates therewith, and second blade can utilize rotary motion
The air being located in gap is driven, and then the air in gap is made to generate centrifugal force and be thrown away to the air outlet direction of turbine, because
This, second blade can prevent air outlet from being returned by gap in the high pressure draught of side and let out air inlet side, to play
Prevent back the effect let out, effectively improves the wind pushing performance of turbine.
Preferably, second blade prolongs from the outer ledge of the outer kuppe to intermediate air inlet curved edge
It stretches.
Preferably, first blade and/or the second blade are projected as in the plane perpendicular to the central axis
Logarithmic spiral curve.Further increase air-flow size and the stationarity of air-flow.

Specifically, several third blades are equipped with around the central axis on the inner wall of the outer kuppe.
Specifically, the third blade is projected as logarithmic spiral curve in the plane perpendicular to the central axis.
The third blade can increase dynamic pressure and the static pressure of air-flow, while improve the acceleration efficiency to air-flow.
Preferably, the inner wall of the interior kuppe is equipped with quaterfoil, the quaterfoil is outside the interior kuppe
Lateral edges extend internally.The quaterfoil can make the air-flow flowed out from the air outlet of turbine gather middle part rapidly, to
Be conducive to air-flow in the middle part of outer cover channel outflow, ensure air-flow to smoothness and stabilization.
Preferably, further including the electric machine assembly for driving the outer kuppe and being rotated with interior kuppe.
Specifically, the electric machine assembly includes PM rotor, wound stator and fixing axle, and the fixing axle is in fix,
The wound stator is fixed in the fixing axle, and the PM rotor is fixed on the pedestal of the interior kuppe inner wall and encloses
It is around in outside the wound stator, bearing is equipped between the fixing axle and the interior kuppe.Turned by the way that the permanent magnet is arranged
Son, wound stator, and the fixing axle and wound stator are fixed to each other, but the fixing axle and the interior kuppe it
Between bearing is set, therefore, the PM rotor can directly drive the interior kuppe operating, to avoid using fixing axle
Rotation output power drive manner, turbine not using fixing axle as center of rotation, operation it is more stable, and stream make an uproar it is lower；In addition,
Since fixing axle does not rotate, the intensity requirement of axis body is reduced, to wanting for the circularity of axis processing, smoothness and concentricity
It asks and is greatly reduced, to advantageously reduce production cost, improve reliability.
Specifically, both fixed fixing piece is equipped between the fixing axle and the wound stator.
