Compared with prior art, the present invention has following beneficial effect:
Described wind wheel in the present invention comprises rotor shaft and blade support, and the central part of described blade support both sides is arranged on the two ends of described rotor shaft by flange, forms symmetrical installation like this, good stability.The present invention has changed existing blade support, the both sides of described blade support form attachment face, described attachment face comprises 5 different-diameters, arrange at equal intervals, the installing ring of concentric setting, that is installing ring is 5, not of uniform size, but when mounted for install setting with one heart at equal intervals, be in same level, installation is reinforced the connection by 10 main muscle, general main muscle is arranged on the side of installing ring, so 5 installing rings connect into an entirety by 10 main muscle, 10 main muscle are that annular array is carried out in the center of circle with rotor shaft simultaneously, such object is to form a stable blade support, in order to improve the stability of whole wind wheel, arrange between blade support, be namely provided with connecting rod between the main muscle of blade support, carry out reinforcement by connection by between main muscle, also have between the installing ring on blade support and be provided with crosspiece, reinforced between installing ring by crosspiece, the blade support of a good stability can be formed thus.
The present invention arranges fan blade on blade support, first order blade is respectively equipped with between adjacent installing ring on blade support, second level blade, third level blade and fourth stage blade, blade support has 10 installing rings, that is the installing ring of equivalent diameter is 5 groups, in adjacent installing ring group, first order blade is set, second level blade, third level blade and fourth stage blade, wherein said first order blade, described second level blade, described third level blade and described fourth stage blade are respectively and are arranged on crosspiece every angle, in other words, the mounting point of second level blade is between 2 adjacent first level blades, in like manner, the mounting point of third level blade is between 2 adjacent second level blades, the mounting point of fourth stage blade is between 2 adjacent third level blades, first order blade and third level blade are that same is diametrically installed, second level blade and fourth stage blade are diametrically installed at same, the present invention also comprises level V blade, described level V blade is positioned on outermost installing ring, be arranged on the connecting rod between 2 main muscle simultaneously, these 2 main muscle lay respectively on the both sides attachment face of wind wheel support, and this level V blade and first order blade, second level blade, third level blade, fourth stage blade are on non-rectilinear and install, the blade of the first order described in the present invention, described second level blade, described third level blade, described fourth stage blade, described level V blade are respectively with pitch motor, the present invention carries out angular adjustment by pitch motor to blade, and each grade blade can according to wind speed and wind speed round adjustment angle like this, and reach under different wind speed, lift is maximum, and resistance is minimum.
Blade in the present invention has 25, and namely the quantity of described first order blade, the quantity of described second level blade, the quantity of described third level blade, the quantity of described fourth stage blade, the quantity of described level V blade are all 5; Such wind wheel of the present invention has 25 fan blades, by the setting to pitch motor, certain limit rotate, such control fan blade just certain angle rotation, when wind come blow time, fan blade will turn to be applicable to the best Windward angle.
Invention increases fan blade frame, suitably add fan blade simultaneously and improve rotor solidity, add 40% than three general leaf machines and reduce threshold wind velocity and rated wind speed, fan blade frame makes fan blade shorten simultaneously, fan blade intensity increases, and wind resistance power improves, and uses wind speed range to broaden.Improve wind energy utilization.
Pyatyi of the present invention become oar be utilize Pyatyi different change oar fan blade to adjust different wind speed, the angle of fan blade not at the same level under different tip speed ratio, reduces the windage of fan blade when high speed operation, reduces windage, improve wind speed round.Improve blower fan benefit.And operating three leaf machines, in order to improve wind speed round, overcome the windage of fan blade when high speed operation at present, fan blade top is done sharp and narrow.The present invention arranges 5 grade blades, and each grade blade can according to wind speed and wind speed round adjustment angle, and reach under different wind speed, lift is maximum, and resistance is minimum, and this point is that three leaf machines are not accomplished.Such as, rotor diameter is the three leaf machines of 70 meters, under near gale speed, if wind speed round is 20 revs/min, now tip speed is 70 meter per seconds, and be, 20 meters away from wind wheel center fan blade speed also have 40 meter per seconds, windage from wind wheel center to blade tip fan blade satisfies gradual change greatly, more larger close to blade tip place windage.Three leaf machine operating principle need when being and starting to increase fan blade vane angle, to increase the blowing area of fan blade, obtain maximum tripping force, during startup, fan blade is synchronous up and down, when after startup, it will obtain maximum lift, make wind speed round the fastest, and maximum lift is vane angle about 12 degree, now maximum for the area that is obstructed of fan blade moving direction high-speed motion fan blade, windage is also maximum, and blade is just asynchronous up and down, and this is conflict, three leaf machines sacrifice blade top area to reduce windage, so it more up does more sharp narrower.And the present invention well solves this problem.
The present invention than many fan blade frames, adds certain windage with three leaf machines, but is the increase in wind wheel frame and makes whole wind wheel out-shift of gravity center, and the inertia of wind wheel increases, and under the effect of inertia, the running of wind wheel is more steady.25 fan blades are arranged on different amount and different intervals, and distribution is more reasonable, and fitful wind and survey wind reduce the impact of wind wheel, and this is also that three leaf machines can not be accomplished.
The present invention reduces to minimum turbine effect, normal conditions, and wind wheel blade is more, and between leaf, speed ratio is lower, and affect speed ratio between leaf except blade profile, also have turbine effect.And although wind wheel blade of the present invention is more than three leaf machines, different with other leafy machine, what the present invention adopted is the lift-type winged petiole meeting power principle.Because blade shortens, mal-distribution is in different directions and different intervals again, and turbine effect impact is relatively little.
The present invention significantly reduces manufacture, transport, installation cost, and reduce the requirement of highway, maintenance is more convenient, and wind energy utilization of the present invention is high in addition, and require low to wind field wind speed, the impact of wind field scale on cost is little, and investment pressure is relatively light.The present invention is more suitable for the bad mountain area of Highway Conditions.
As from the foregoing, the present invention can solve deficiency of the prior art, and this device adds fan blade, add rotor solidity, reduce fan starting wind speed, reduce wind field condition, become oar by Pyatyi classification, meet blade at different layers, tune oar requirement under different wind speed, fan blade shortens, and reduces and manufactures transport installation difficulty, alleviate cost, realize better wind-power electricity generation.
