The incoming flow power conversion of the present embodiment: as shown in Figures 1 and 2, the setting angle of blade of the first impeller 3 and the second impeller 3 ' is contrary, Ji Yanqi center vertical plane axisymmetricly, when incoming flow impacts the second impeller from the right direction, the second impeller can be rotated counterclockwise (from the second impeller frontal) under incoming flow effect, then incoming flow will continue to impact the first impeller, because the first impeller is contrary with the stagger angle of the second impeller, so now the first impeller can carry out clockwise direction (from the second impeller frontal) rotation, thereby realize the mechanical energy that the power conversion of incoming flow is become to impeller.
The turbomachine of the present embodiment can transmit: as shown in Figure 5, the energy of realizing the second impeller by being used in combination the 4th ratchet 12 ' that teeth groove rotation direction is identical and the second ratchet 18 ' and interior outer shaft transmits the mechanical energy transfer device of impeller.Because the second impeller 3 ' are dynamically connected by axle 8 in ratchet 18 ' and generator, with the second outer shaft 7 ' for being fixedly connected with, so when the second impeller 3 ' are rotated counterclockwise (from the second impeller frontal), now the second impeller 3 ' are driving link, thereby drive external tooth 2 and the second outer shaft 7 ' of the second ratchet 18 ' of its inside to be therewith rotated counterclockwise, relative its internal tooth (1) 1 of the external tooth 2 of the 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 ' is known, now external tooth 2 rotation directions and internal tooth (1) 1 cannot coincide, so the second impeller is rotated counterclockwise internal axle 8 and has no effect, again because the second outer shaft 7 ' and generator external rotor 6 are dynamically connected by the 4th ratchet 12 ', so when the second outer shaft 7 ' are rotated counterclockwise, can drive the internal tooth 1 of the 4th ratchet 12 ' that are fixedly connected with the second outer shaft 7 ' to be rotated counterclockwise simultaneously, the external tooth 2 of relative the 4th ratchet 12 ', now the internal tooth 1 of the 4th ratchet 12 ' is driving link, from Fig. 5, the known internal tooth being rotated counterclockwise 1 of the teeth groove rotation direction of this gear just in time matches with external tooth 2 teeth groove, thereby drive external tooth 2 to be rotated counterclockwise, and then the generator external rotor 6 that drive is fixedly connected with external tooth 2 is rotated counterclockwise simultaneously, and being rotated counterclockwise of the second impeller affects internal rotor 5 nothings.
With respect to the second impeller 3 ', now 3, the first impeller is clockwise direction rotation, the energy transmission device of the first impeller 3 and ratchet teeth groove rotation direction are identical with the second impeller 3 ''s, as shown in Figure 6, the energy of realizing the first impeller 3 by the 3rd identical ratchet 12 of teeth groove rotation direction and the first ratchet 18 transmits, so when the first impeller 3 turns clockwise, drive external tooth 2 and first outer shaft 7 of the first ratchet 18 of its inside to turn clockwise, from Fig. 6, the teeth groove rotation direction of the ratchet 18 of the first impeller 3 is known, now external tooth 2 rotation directions and internal tooth 1 match, thereby realize, drive interior axle 8 to turn clockwise, again because interior axle 8 is fixedly connected with internal rotor 5, so the first impeller 3 drive internal rotors 5 turn clockwise (now external rotor 6 is for being rotated counterclockwise), the same with the second outer shaft 7 ', the first outer shaft 7 is to be also dynamically connected with external rotor 6 by the 3rd ratchet 12, because the first outer shaft 7 is now for turning clockwise, so drive the internal tooth 1 of the left side ratchet 12 being fixedly connected with it to turn clockwise, external tooth 2 with respect to this ratchet, now the internal tooth 1 of this ratchet is driving link, but the internal tooth 1 and the external tooth 2 that turn clockwise cannot coincide, so the external rotor 6 being fixedly connected with external tooth 2 is not affected by lobus sinister wheel, the lobus sinister wheel turning clockwise only can drive internal rotor to turn clockwise, and to external rotor without any active force.
In summary, the second impeller 3 ' that are rotated counterclockwise only can drive external rotor 6 to be rotated counterclockwise, and 3, the first impeller turning clockwise can drive internal rotor 5 to turn clockwise, thereby realize inner-outer birotor counter-rotating simultaneously.When first incoming flow impacts the first impeller 3 from left direction, now 3, the first impeller is for being rotated counterclockwise (watching visual angle with identical, from lobus dexter wheel front) above, and the second impeller 3 ' are for turning clockwise; The same with above-mentioned energy transfer principle, now the first impeller 3 continues drive external rotor 6 to keep being rotated counterclockwise, the second impeller 3 ' continue drive internal rotor 5 to keep turning clockwise, thereby realize the no matter direction of rotation of two impellers, how to change, the internal rotor 5 of this generator and the direction of rotation of external rotor 6 can remain constant.
Electric energy output in the present embodiment: on the first outer shaft 7 of generator, two collector rings 14,15 are housed respectively; in figure, the first collector ring 14 is arranged on unofficial biography 6 inside; the second collector ring 15 is arranged on external rotor 6 outsides; containment vessel is inner; and two collector rings are fixedly connected with by wire, conductor arrangement is in the surface, inside of the first outer shaft 7.The electric weight that in stator, winding produces in electromagnetic induction; collection by stator interior the first collector ring 14 is delivered on the second collector ring 15 above motor outer shaft; then by these the second collector ring 15 extracting power supply cords, through fixed protecting sheathing 4, electricity is derived.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
