Embodiment
Fig. 1 is the structure diagram of looking squarely of seat-stand type wind turbine system of the present invention.In Fig. 1, the blade of turbo machine (1) is in the position, the narrowest air channel, centre of the water conservancy diversion cell body that is made of wind guiding member (2), enter whole distinguished and admirable in the wind guiding member and all be subject to the central authorities that guide functions flows to cell body, formation blows to turbo machine than the concentrated kinetic energy that original wind speed is high, density is large, so the blade of turbo machine does not just need original three so long, the so few blades of picture, just can be with reference to the short blade in steam turbine or the gas turbine and multiple-blade form, and employing middling speed turbine blade, and single-stage or multistage turbine blade.Conduct signal among the figure, six blades that draw, it is a kind of signal scheme, the quantity, shape and the progression that comprise the concrete blade of turbo machine of wind guiding member design, should learn principle according to the air foundation, the greatly different difference of difference low speed and at a high speed lower turbo machine parameter, therefore, system of the present invention turbo machine (1) should be according to turbine bucket place wind speed range, and, blade quantity linear by the middling speed turbine blade and impeller progression manufacture and design.
Determined middling speed turbine blade is linear, blade quantity and impeller progression manufacture and design.
Generator of the present invention (3) and the direct shaft coupling of turbo machine, generator can be the direct-driving type synchronous alternator, comprise excitation-type and magneto synchronizer, can be half direct-driving type synchronous alternator or the double-fed asynchronous alternator of half direct-driving type, if the rotating speed of turbo machine is enough high, also can adopt the double-fed asynchronous alternator of direct-driving type, in the not high enough situation of turbine speeds, between turbo machine and alternator, can increase the gear-box speedup, to improve the rotating speed of synchronous generator or induction generator.Because generator speed improves, the present invention weakens the dependence of gear-box, is beneficial to directly the driving of wind-powered electricity generation.Also can adopt synchronous/asynchronous secondary electricity generation machine, its advantage shows that elongated body diameter is little to distinguished and admirable resistance, and absolute non-brushing, sees the asthenic wind-driven generator that Chinese patent ZL200420091099.2 low-speed toothless roller box directly drives for details.
Fig. 2 is the plan structure sketch of seat-stand type wind turbine system.After this figure is actually upper half part cutting of a width of cloth with wind guiding member (2), overlook from top to bottom the structural representation that can see, it is thin that wind guiding member (2) is equivalent to one section centre, and the tube seat that two ends are thick, turbine generation unit just are positioned at the narrowest position, tube seat middle part.Wind guiding member (2) be the aerodynamically principle design, can will concentrate on the deflector correct position after distinguished and admirable concentrated, the supercharging in the large size, the acceleration, the turbo machine of settling in this position just can produce ratio without the much better than wind energy of the unit of wind guiding member, rotating speed and the output power of turbo machine are had a distinct increment, the research data of the relevant guide-type vertical-axis wind turbine of energy and power engineering engineering college of Shanghai University of Science and Technology shows, under identical inlet flow conditions, the total torque that adds the guide flowing type wind energy conversion system is larger nearly 9 times than the moment of torsion of the wind energy conversion system of nothing stator.
Wind guiding member has two large types---rigid body structure and flexible construction, the rigid body structure is made of thin-wall metal material, plastics, glass fibre reinforced plastics, wood material and supporter thereof usually, wind guiding member structure such as thin-wall metal material or glass fibre reinforced plastics, its front and rear edge is fixed on the seat stand platform by many position, in the schematic representation with 6 stake bit representations, quantity and the position of actual stake position determine to guarantee wind guiding member enough rated wind velocity are arranged as required.And the wind guiding member among Fig. 1 (2) front and rear edge adopts the whole mount scheme that is connected with the seat stand platform, and mounting structure is slightly different from Fig. 2.
Recently, adopt the flexible construction thing of membrane structure in building industry, to obtain considerable application, so membrane structure also is well suited for building wind guiding member.The new building structural types such as membrane structure or title rope membrane structure, inflatable membrane structure, Tensioned Membrane Structures, skeleton membrane structure, combination membrane structure can be used widely in wind guiding member.
Seat stand (4) is as the carrier of unit, and its large small scale is relevant especially with the wind guiding member design.Wind guiding member drawn among Fig. 1 and Fig. 2 is smaller, and actual wind guiding member size can be more much bigger than seat stand outer rim.
Figure 3 shows that the plan structure sketch of the seat-stand type wind turbine system of larger wind guiding member.At this moment the wind guiding member outer rim has exceeded the seat stand platform, except the centre with the fixing wind guiding member in 2 stake positions, front and rear edge then adopts the whole mount scheme that is connected with the seat stand platform, if the intensity of wind guiding member fully seat table top own is long-pending firm, should there be extra robust structure to support, perhaps by local extended structure, the two is mutually fastening to make wind guiding member and seat stand, to reach stronger wind loading rating.
The weight of whole turbo machine and generator unit or turbo machine, gear-box and generator set assembly acts on the seat stand central shaft by the seat stand bearing, and the weight of part of generating units assembly and the weight of wind guiding member also act on the seat stand platform simultaneously.
For ease of the installation and maintenance maintenance, there is hatch can lead to seat stand train part at the seat stand platform, so Fig. 2 can see the position of train.
Fig. 4 is the side-looking simplified diagram of seat stand section.Seat stand among the figure (4) mainly is made of seat stand axis (41), seat stand bearing (42), seat stand platform (43), mounting (44) and seat stand train (45).
Seat stand axis (41) is in the central position of seat stand (4), perpendicular to ground surface platform, and water and be fixed in the ground, by seat stand bearing (42), whole seat stand body can rotate in horizontal plane around seat stand axis (41), represented up and down two bearings among the figure, and top one is cod, following one is radial bearing, illustrates that the weight distribution of whole unit is fastened at axle and wheel.Bearing can be sliding bearing, also can be ball or roller bearing.
Seat stand axis (41) can be used hollow structure, and the above can be installed slip ring additional, and brush then is installed in the position of corresponding slip ring on the seat stand, is convenient to allow system and ground installation send mutually electric power, and cable then passes axis and connects electrical network.Certainly also can as conventional rack, adopt the direct transmitting electric power of cable and increase the cable anti-winding function and omit slip-ring brush.
Seat stand platform (43) is for the plane of installing and supporting unit; Fig. 5 is the seat stand section side-looking simplified diagram that loading only acts on foundation platform; two seat stand bearings (42) among the figure all adopt radial bearing; mean that seat stand axis (41) only plays the anti-sidesway effect in location, no longer bears the weight of unit basically.Unlikely two groups of seat stand bearing (42) possibility among Fig. 4 and Fig. 5 also may have many groups, comprises radial bearing and cod.
The equipment such as unsteady flow, control, protection of sufficient space installation system is arranged on the seat stand platform, and transformer and electric substation also can be arranged on the platform.The outer ground of platform arranges short ladder, to make things convenient for the work of personnel's upper mounting plate.
Be mounting (44) below seat stand platform (43), mounting (44) is the structure that connects seat stand platform (43) and seat stand train (45).
Seat stand train (45) is the supporting mass that all or part of weight of unit is landed, and simultaneously whole system can freely be rotated in horizontal plane, so be the important structure thing of system.Train is one group and is in respect to the equidistant and equally distributed wheels of axis, in order to increase load, can many group wheels be set at different radii.
The seat stand train can adopt heavily loaded solid rubber tire or inflation rubber tire, also can adopt steel wheel or rail wheel.Common and the I-steel adapted of steel wheel, I-steel is layered on the foundation platform and fixes, and when adopting rail wheel, can adopt heavy steel rail to be layered on the foundation platform under the rail wheel and also fix.
Fig. 6 is a kind of rail mounted seat stand train (45) with the anti-dumping barb, among Fig. 6, the connecting body of train and seat stand platform (452) is called " T " cabinet frame, its lower end arrives below the bearing of train, drive motor and break (454) drive or braking orbit wheel (453) rotates, and realize that many motors disperse to drive." A " cabinet frame (451) top and bottom are fixed on " T " cabinet frame, there is barb protrusion (4511) two lower end, and protrusion embeds the track vertical component but can not contact with track, can prevent that rail wheel is derailed, can prevent again the high wind system of throwing, increase Security of the system.The another kind of structure that combines with deflection braking and overturning-preventing is called embraces the rail arrestment mechanism, does not establish break in the drive motor (454 '), at ordinary times, embraces rail mechanism and always embraces the track both sides, makes system's locking in orbit; Before the seat stand platform needs deflection, an armful rail mechanism is taken off embrace, and then start the drive motor running, system walks in orbit, and drive motor running end is embraced a rail mechanism and is again embraced rail.
Except above-mentioned train drive scheme, the another kind of seat stand that drives rotates, reach the scheme of going off course to the wind target and be called centralized driving, locate to arrange drive motor at seat stand axis (41) exactly, engagement by axis and drive motor gear mesh, whole seat stand just can deflection, and break is arranged in the motor simultaneously.Concerning system, or adopt the train of disperseing to drive, or be that the axis of concentrating drives.
Seat stand (4) is the carrier of unit, can in horizontal plane, rotate wind, namely in during low wind speed, the function of driftage is carried out in seat stand deflection, over against the direction of the wind comes from, to obtain the multiple electricity of maximum wind energies; When high wind speed very, also can carry out and transfer the wind function, namely when surpassing the high wind of original blower fan cut-out wind speed, make unit depart from angle of positive wind direction and continue generating, in fact reached the purpose of regulating air quantity, as seen wind guiding member can make low wind speed become high wind speed, reduces the incision wind speed, in advance generating; And under high wind, the accent wind function that system departs from positive wind direction can improve again cut-out wind speed, makes the state that originally must abandon the machine of becalming change into continuation energy electrogenesis, and the generating capacity of system of the present invention is higher than existing traditional horizontal axis blower fan thus.
Because the raising of system power, braking becomes the critical function of protection unit safety, and native system is to rotate wind sheltering by seat stand, progressively reduces turbine speeds; Drop under the safety value that is fit to braking when turbine speeds, break just starts realizes braking, reaches the purpose of auxiliary braking.
From above narration, can find, the present invention is concentrated to turbo machine by wind guiding member with wind energy, even so under identical cut-off wind area, its wind energy of catching all may be larger than traditional three leaf turbo machines, can obtain more windy electricity, also solve manufacturing and the Cost Problems of turbine bucket length simultaneously.Because turbine speeds raises, the volume weight of generator can correspondingly reduce, and efficient also gets a promotion simultaneously, and is also so serious unlike existing large fan to the dependence of gear-box.
Second largest characteristics of the present invention are to have adopted the seat stand structure; if from adopting wind guiding member; the seat stand structure is seemingly tackled the passive act that the water conservancy diversion cell body is installed; but; consider that from positive face seat stand can rotate wind in horizontal plane, carry out driftage, transfer wind and auxiliary function of shutting down braking; its installation and maintenance are carried out on ground basically, also help maintaining.
Although increase additional weight and cost that wind guiding member and seat stand can increase system, but the weight of fan blade and generator can alleviate, add the cancellation of tower cylinder, gear-box may be cancelled the weight of bringing and subdue, and might make system unit power weight indicator surmount conventional rack.
The present invention is named the 10MW level; though only refer to other wind turbine group of current super sized type level; but and do not mean that the present invention only limits to the machine set system of this grade; protection scope of the present invention after obtaining practical operating experiences, also can be used for high power rank and other other power rank units of low power level, so should comprise the wind power system of the various power levels that adopt structure of the present invention.
