Abstract
The utility model belongs to the field of a wind driven generator, in particular to a rotating cantilever of a megawatt-level vertical axis wind driven generator. The structure of the cantilever has the following structure that a rotary disk on a tower cylinder is respectively connected with one ends of a horizontal straight arm and an inverse arched flexible rope, a vertically-distributed blade is further connected with the other ends of the straight arm and the inverse arched flexible rope, the straight arm is arranged above the arched flexible rope, and a series of pendulous pull rods or pull ropes are connected between the straight arm and the inverse arched flexible rope. The cantilever ingeniously utilizes the structure of an inversely-opened steel rope, transmits the load applied to the top of the cantilever to the root of the cantilever, effectively overcomes the defect of the unstable rigidity of the cantilever, and has the performance characteristics of being simple in structure, small in wind baffling area, low in manufacturing cost, easy to increase the single-machine capacity, and the like.
Description
Technical field
The utility model belongs to wind power generation device field, particularly the hinged cantilever of MW class vertical axis aerogenerator.
Background technique
Wind-power electricity generation is the at present both economical and easy renewable energy sources that realizes large-scale commercial applicationsization, belongs to green clean energy resource again, is 21 century one of the emphasis of scientific and technological development in the world.Wind-driven generator is divided into horizontal axis wind-driven generator and vertical axis aerogenerator.The jib-length of present MW class vertical axis aerogenerator is about 30～50 meters, the unsettled blade of hanging, and the other end connects tower tube rotating disk, is overlength single-cantilever structure.The cantilever of large-scale vertical wind-driven generator is because of oversize insufficient rigidity, and this is the biggest problem of MW class cantilever of vertical shaft wind driven generator.For reducing windage, cantilever should be thin as far as possible in the size of Vertical direction; For increasing rigidity, cantilever again should be thick as far as possible in the size of Vertical direction.No matter this is to adopt truss structure, or adopt other beam structure to make cantilever to contradiction, all can not be properly settled.Because the cantilever rigidity is not enough, prior art can only add cable wire by top and improve rigidity at the height of cantilever rotating disk top increase tower tube, but can increase the manufacture cost of tower tube like this.
Document for a lot of patented technologies of wind-driven generator, great majority concentrate on raises the efficiency, reduce the windage aspect, as 200510045895.1 (a kind of vertical shaft high power wind-driven generators), 200720010733.9 (vertical axis windmills), 200810026323.2 (one-arm multi-leaf vertical axis wind mill).Technology report about the cantilever aspect is less, and one piece of 200710111746.X (blade supporting arm of vertical axis aerogenerator) is only arranged.From above-mentioned these files, all do not find to solve the description of cantilever stiff problem, and from literal and pattern, cantilever structure still concentrates on truss structure or shell construction.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reverse guy rope type cantilever of vertical shaft wind driven generator, it can solve the stiff problem of large-scale vertical wind-driven generator cantilever, overcoming existing cantilever force concentrates, the shortcoming that occurs the rigidity unstability easily, the while does not increase the construction cost of tower tube again.
Solving the scheme that technical problem of the present utility model adopts is:
Rotary disk on the tower tube is connecting an end of horizontal straight-arm and the gentle rope of invert shape respectively, vertically arranged blade is connecting the other end of straight-arm and the gentle rope of invert shape again, straight-arm is positioned at the gentle Suo Shangfang of invert shape, is connected with a series of pull bars that hang down or drag-line between straight-arm and the gentle rope of invert shape.
Also be connected with an oblique arm between the rotary disk of horizontal straight-arm described in the utility model below and the blade, its tilt angle is 0 °～60 °.
The two ends of the gentle rope of invert shape described in the utility model are compiled with the two ends of oblique arm respectively.
When the blade that uses for generator was longer, the reverse guy rope type cantilever of the said structure of support blade adopted 1～3 cover.
The utility model dexterously with the structure applications of falling the vang of bridge to the large-scale vertical wind-driven generator cantilever, the load transfer that blade is imposed on cantilever top is distributed to the other parts of cantilever, especially transfers to the root of cantilever.Can alleviate the following curved moment that cantilever bears greatly like this, promote the rigidity of cantilever relatively.Therefore, cantilever just can be made very thinly, with the requirement of aerodynamic.When guaranteeing the satisfied rigidity of acquisition, reduce wind-exposuring area again, obtain little windage, improve the wind-powered electricity generation conversion efficiency of complete machine.
The beneficial effects of the utility model are:
(1) (adopt identical blade) under identical electric motor power, the weight of reverse guy rope type cantilever is less than 70% of traditional truss structure cantilevered weights, and manufacturing process is simple, and manufacture cost reduces by 40%; (2) the reverse guy rope type cantilever is thinner in the vertical height direction than the cantilever of truss cantilever or other beam structure, makes the choke area of cantilever littler, and the wind-powered electricity generation conversion ratio is higher, and adaptability is stronger; (3) the reverse guy rope type cantilever with on draw the cantilever of cable wire to compare, can reduce tower tube total height, save tower tube cost.(4) the position of vang and bearing diagonal arm is relatively low, and effect wind speed thereon is also less relatively, has both made things convenient for installation, can further reduce windage again.(5) alleviating of cantilever of vertical shaft wind driven generator weight, load and deadweight that a series of parts such as wind-force unit support tower tube are born alleviate greatly, and the manufacture cost of whole wind force generating system is significantly reduced.
