Description
Technical field
The utility model wind power generation field, is specifically related to a kind of full load without the wheeled wind generating unit of brake, is specially adapted to various large-scale wind power field institute.
Background technique
At present, the device that is widely used in wind-power electricity generation is mainly horizontal axis wind-driven generator, and horizontal axis wind-driven generator adopts the three fan blade patterns of installing on wheel hub mostly.Such Design Mode is few due to blade being installed, and to impeller, generally speaking blowing area is less, and generated energy is less and overall efficiency is low.Have vertical axis aerogenerator, because fan blade aeroperformance is poor, overall efficiency is not high yet yet.Be exactly to consider for whole blower fan Safety performance under high wind in addition, nearly all wind-driven generator arrives with braking device, braking device mechanism is to stop wind wheel to rotate by friction, so a large amount of wind energies has all been wasted, and complex structural designs, installation difficulty is large, safeguards inconvenience, and cost is higher.
For wheel type wind driven generator, technology is also announced to some extent at present, " anti-strong wind power generator " that such as notification number, be CN100427862C is exactly a kind of large-scale wheel-type electric generator, the switching of employing wind scooper regulates the size of wind wheel air output, though solved like this impact of high wind to wind wheel, but also reduced the generating efficiency under large wind condition, do not make full use of wind energy, as to large-scale wind generating, the wind scooper of this kind of method is difficult to manufacture and install, and the switching of wind scooper is adjusted by rope, dangerous also unreliable, there is major hidden danger.There is inventor to disclose a kind of wheel type wind driven generator, notification number is that CN101603509A's " reinforced type wind-driven generator " this kind of design adopts oblique pull lock to strengthen the fixing of fan blade, operation under high wind is had to certain reinforcement effect, but it has designed impeller supporting frame simultaneously, many generators and light-duty supporting wheel are installed on impeller supporting frame, this kind manufactures and designs difficulty, particularly to large-scale wind driven generator, impeller and the impeller supporting frame of ten meters of diameters or tens meters are difficult to manufacture, as adopt segmentation manufacture, be difficult to guarantee again the conformity of every section of circular arc, may cause misalignment, there is potential safety hazard, be fixed on generator drive wheel on impeller supporting frame and the side close contact of impeller transmission supporting surface simultaneously, because impeller supporting frame and impeller are all fixed installations, generator on impeller supporting frame is also fixed installation, because impeller transmission supporting surface and generator drive wheel close contact run up for a long time, very fast two surface of contact just have wearing and tearing, and then the frictional force between reduction by two surface of contact, cause generator and wheel speed ratio to decline, generating efficiency reduces, because this kind of design changes at wind speed, be there is no good brake measure simultaneously, there are major safety risks.There is inventor on this basis for solving the defect of adjusting wind speed and braking aspect, a kind of wheel type wind driven generator is disclosed, notification number is that CN103147926A's " full blade tip wind-driven generator " this kind of design adopts and on horizontal axis, adopt fluid brake, when high wind, adopt mechanical type hydraulic braking brake, manufacture and design difficulty, owing to only having braking scheme one, once there is brake failure when high wind, to cause major safety risks, simultaneously under large wind, braking device also may start and brake, make the reduction of exerting oneself of wind-driven generator, generated energy and the generating efficiency of wind-driven generator have been reduced, its kind of drive is outer close contact, very fast two surface of contact just have wearing and tearing, and then the frictional force between reduction by two surface of contact, cause generator and wheel speed ratio to decline, generating efficiency reduces.
In sum, existing large-scale wind driven generator is generally that fan blade design is unreasonable, and braking system is unreasonable, and the field energy that do not have can full load to keep watch converts electric energy to, blower fan is exerted oneself low, and generating efficiency is low and cost is high, manufactures difficulty, control system is complicated, and safety reliability is low, and above problem is urgently to be resolved hurrily.
