The stream energy that comes of the present embodiment is changed: as shown in Figures 1 and 2, the blade angle of the first impeller 3 and the second impeller 3 ＇ is contrary, Ji Yanqi center vertical plane is axisymmetricly, when flow impact the second impeller from direction, the right time, second impeller can rotate (in terms of the second impeller leading faces direction) under the effect of flowing counterclockwise, then carry out stream to will continue to impact the first impeller, owing to the established angle of the first impeller and the second impeller is contrary, so now the first impeller can carry out (in terms of the second impeller leading faces direction) rotation clockwise, thus realize the energy flowed to be converted into the mechanical energy of impeller.
The turbomachine of the present embodiment can transmit: the mechanical energy transfer device of impeller is as it is shown in figure 5, by being applied in combination teeth groove rotation direction the 4th identical ratchet 12 ＇ and the second ratchet 18 ＇ and interior outer shaft realizes the energy of the second impeller and transmits.Because the second impeller 3 ＇ is dynamically connected with axle in electromotor 8 by ratchet 18 ＇, it is connected for fixing with the second outer shaft 7 ＇, so when the second impeller 3 ＇ rotates counterclockwise (in terms of the second impeller leading faces direction), now the second impeller 3 ＇ is driving link, thus drive the external tooth 2 and the second outer shaft 7 ＇ of its second internal ratchet 18 ＇ to rotate the most counterclockwise, external tooth 2 its internal tooth (1) 1 relative of i.e. second ratchet 18 ＇ is driving link, from Fig. 5, in the second impeller 3 ＇, the rotation direction of the external tooth 2 of the second ratchet 18 ＇ understands, now external tooth 2 rotation direction cannot be coincide with internal tooth (1) 1, so the second impeller rotates internal axle 8 counterclockwise and has no effect；Again because the second outer shaft 7 ＇ is dynamically connected by the 4th ratchet 12 ＇ with electromotor outer rotor 6, so when the second outer shaft 7 ＇ rotates counterclockwise, the internal tooth 1 fixing the 4th ratchet 12 ＇ being connected with the second outer shaft 7 ＇ can be driven to rotate the most counterclockwise, the external tooth 2 of relative 4th ratchet 12 ＇, now the internal tooth 1 of the 4th ratchet 12 ＇ is driving link, the internal tooth 1 rotated counterclockwise knowable to the teeth groove rotation direction of this gear from Fig. 5 just matches with external tooth 2 teeth groove, thus drive external tooth 2 to rotate counterclockwise, and then drive the electromotor outer rotor 6 that be connected fixing with external tooth 2 to rotate the most counterclockwise, and the counterclockwise of the second impeller rotates internal rotor 5 without impact.
Relative to the second impeller 3 ＇, now the first impeller 3 is then for being rotated clockwise, energy transmission device and the ratchet teeth groove rotation direction of the first impeller 3 are identical with the second impeller 3 ＇, as shown in Figure 6, i.e. realize the energy of the first impeller 3 by identical the 3rd ratchet 12 of teeth groove rotation direction and the first ratchet 18 to transmit, so when the first impeller 3 turns clockwise, the external tooth 2 and the first outer shaft 7 that drive its first internal ratchet 18 turn clockwise, from Fig. 6, the teeth groove rotation direction of the ratchet 18 of the first impeller 3 understands, now external tooth 2 rotation direction matches with internal tooth 1, thus realize driving interior axle 8 to turn clockwise, it is connected because interior axle 8 is fixing with internal rotor 5 again, so the first impeller 3 drives internal rotor 5 to turn clockwise (now outer rotor 6 is for rotating counterclockwise)；As the second outer shaft 7 ＇, first outer shaft 7 is also to be dynamically connected with outer rotor 6 by the 3rd ratchet 12, owing to now the first outer shaft 7 is for turning clockwise, so driving the internal tooth 1 of the left side ratchet 12 being secured to connection to turn clockwise, external tooth 2 relative to this ratchet, now the internal tooth 1 of this ratchet is driving link, but the internal tooth 1 turned clockwise cannot coincide with external tooth 2, so the outer rotor 6 that be connected fixing with external tooth 2 is not affected by lobus sinister wheel, the lobus sinister wheel i.e. turned clockwise only can drive internal rotor to turn clockwise, and to outer rotor without any active force.
In summary, the second impeller 3 ＇ rotated counterclockwise only can drive outer rotor 6 to rotate counterclockwise, and the first impeller 3 turned clockwise only can drive internal rotor 5 to turn clockwise, thus realizes inner-outer birotor counter-rotating simultaneously.When flow first impact the first impeller 3 from left direction time, now the first impeller 3 is then to rotate counterclockwise (viewing visual angle is same as above, i.e. in terms of right impeller leading faces), and the second impeller 3 ＇ is for turning clockwise；The same with above-mentioned energy transfer principle, now drive outer rotor 6 is continued to keep rotating counterclockwise by the first impeller 3, drive internal rotor 5 is continued holding and turns clockwise by the second impeller 3 ＇, thus how the direction of rotation realizing no matter two impellers changes, the internal rotor 5 of this electromotor and the direction of rotation of outer rotor 6 can remain constant.
Electric energy output in the present embodiment: be respectively provided with two collector rings 14,15 on the first outer shaft 7 of electromotor; in figure, the first collector ring 14 is arranged on unofficial biography 6 inside; it is outside that second collector ring 15 is arranged on outer rotor 6; inside containment vessel; and two collector rings connect by wire is fixing, and wire arrangements is in the interior surface of the first outer shaft 7.Winding produced electricity in electromagnetic induction in stator; it is delivered on the second collector ring 15 above motor outer shaft by the collection of stator interior the first collector ring 14; then by this second collector ring 15 extracting power supply cord, through fixed protection shell 4, conductance is gone out.
The above is only the preferred embodiment of the present invention; it is noted that, for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
