Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
Tidal generation water turbine, comprise: shell, be placed in first impeller 2 and second impeller 5 at shell two ends, be connected to the transmission shaft 7 of the first impeller 2 and the second impeller 5, be connected to the unidirectional transmission 3,4 between transmission shaft 7 and the first impeller 2, second impeller 5, be connected to the generator 8 of transmission shaft 7; The blade tendency of the first impeller 2 and the second impeller 5 is contrary.
Shell composition has: the sleeve pipe 9 of parcel transmission shaft 7 and generator 8, and water pipe 6 restrainted by the first bundle water pipe 1, second being placed in sleeve pipe 9 two ends; First bundle water pipe 1, second restraint water pipe 6 diameter by with the joint of sleeve pipe 9 outwards increase gradually, form gradually open form shape, be more conducive to collecting the trend of pouring into.
Unidirectional transmission 3,4 composition has: ratchet 15 pawl 10 being articulated with the first impeller 2, second impeller 5, is placed in the spring 11 of ratchet 15 pawl 10, is connected in the ratchet 15 of ratchet 15 pawl 10; The edge of ratchet 15 is provided with ratchet 15 tooth 12, and ratchet 15 tooth 12 is provided with the stressed side 13 being connected in ratchet 15 pawl 10, is connected to the slip side 14 of stressed side 13.When the first impeller 2 rotates clockwise, driving ratchet 15 pawl 10 hinged with it to rotate together with spring 11, moves in the stressed side 13 that ratchet 15 pawl 10 withstands ratchet 15 tooth 12, drives the transmission shaft 7 be connected with ratchet 15 to rotate clockwise; When impeller rotates counterclockwise, drive ratchet 15 pawl 10 hinged with it to rotate together with spring 11, ratchet 15 pawl 10 slides along the slip side 14 of each ratchet 15 tooth 12 and not to ratchet 15 transmission, impeller idle running and transmission shaft 7 does not turn.
Unidirectional transmission 3 is set as transmission clockwise only; The blade tendency of the first impeller 2 and the second impeller 5 when being set as making left side incoming flow the first impeller 2 to rotate clockwise and the second impeller 5 rotates counterclockwise, during the incoming flow of the right, the first impeller 2 rotates counterclockwise and the second impeller 5 rotates clockwise.In like manner, also can be: when the blade of the first impeller 2 and the second impeller 5 tendency is set as making left side incoming flow, the first impeller 2 rotates counterclockwise and the second impeller 5 rotates clockwise that during the incoming flow of the right, the first impeller 2 rotates clockwise and the second impeller 5 rotates counterclockwise.Sense of rotation complies with the rotor sense of rotation required by generator 8.The transmission direction of unidirectional transmission 3,4 turns to consistent with the regulation of generator 8.When impeller rotates clockwise, impeller can drive transmission shaft 7 to rotate together; When impeller rotates counterclockwise, then impeller freely dallies and not to transmission shaft 7 transmission.When using this water turbine to generate electricity, water turbine is placed in the marine site of obvious trend phenomenon, water turbine is flooded by seawater completely, impeller shaft to rise, ebb tide direction is parallel, because the general direction of fluctuation tide differs 180 °, make to rise, ebb tide trend stream flows into by the two ends of water turbine respectively.
Preferred as one, generator 8 also can use fixed support to be arranged on sleeve pipe 9 top, as shown in Figure 5, adopts parallel drive device 19 transmission between generator 8 and transmission shaft 7.Parallel drive device 19 is provided with between generator 8 and transmission shaft 7; As shown in Figure 4, parallel drive device 19 composition has: the first driving gear 18 being connected to transmission shaft 7, is connected to the second driving gear 16 of generator 8, is connected in the drive chain 17 of the first driving gear 18, second driving gear 16; By drive chain 17, the rotation of the first driving gear 18 is transmitted to the second driving gear 16, second driving gear 16 to be connected with generator 8, drive electrical generators 8 generates electricity.
As Fig. 1, when direction of tide be left side time water turbine working procedure: when flood current direction is left side incoming flow, current first flow through the left side first restraints water pipe 1, and flow velocity is strengthened, flow to impeller shaft to deviation corrected; The first impeller 2 on the left of water jet propulsion rotates clockwise, and carries out transmission by unidirectional transmission 3 to transmission shaft 7, and the rotor turns of drive electrical generators 8 generates electricity, and now the first impeller 2 is motive power wheel; On the right side of water jet propulsion, the second impeller 5 rotates counterclockwise and flows out water turbine afterwards, and the second impeller 5 does not rotate to transmission shaft 7 transmission by unidirectional transmission 4 because rotating counterclockwise, and self idle running, therefore now the second impeller 5 is free pulley.
As Fig. 2, the working procedure of water turbine when direction of tide is right side: when through the turn of tidal stream moment, trend becomes ebb current, flows into by the right side of water turbine, and current first flow through the second bundle water pipe 6, and flow velocity is strengthened, flow to impeller shaft to deviation corrected; Water jet propulsion second impeller 5 rotates clockwise, and carries out transmission by unidirectional transmission 4 to transmission shaft 7, and the rotor turns of drive electrical generators 8 generates electricity, and now the second impeller 5 is motive power wheel; On the right side of water jet propulsion, the first impeller 2 rotates counterclockwise and flows out water turbine afterwards, and the first impeller 2 does not rotate to transmission shaft 7 transmission by unidirectional transmission 3 because rotating counterclockwise, and self idle running, therefore now the first impeller 2 is free pulley.
The shell of this water turbine adopts pipe type, thus generating efficiency is influenced little when the turn of tidal stream moment flow direction and rotor shaft direction exist angle, and there is not general pipe type hydraulic turbine blade rotation increase system complexity problems; Generator 8 two ends adopt the impeller of different leaves tendency to realize the generating of reversing current, avoid the rotation in impeller direction and the rotation of blade tendency, simplify system, be conducive to the industrialization of tidal power generating and the development of small hydropower station and ocean energy isolated power system; The present invention judges the opportunity of impeller or blade rotation without the need to artificial or computer, and the completely spontaneous response for changing flowed to trend, improves system effectiveness; The structural design of free pulley can weaken the flow turbulence in water turbine wake flow, is conducive to improving generating efficiency.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technological scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
