Description
Technical field
The utility model relates to a kind of wind energy conversion system generator techniques apparatus field, particularly a kind of blade of vertical axis wind turbine anti-collision equipment.
Background technique
Multiple blade rings that wind-power electricity generation function is crossed on Wind power propelling wind wheel turn round around vertical shaft, drive generating machinery to produce electric energy; Traditional lift vertical shaft pneumatic equipment blades made is fixed relative to wind wheel arm, and this wind energy conversion system starts very difficult; In order to effectively utilize wind energy, solve self-starting problem, some vertical axis windmills increase resistance type blade on lift-type blade basis, but this blower fan resistance type blade when high rotating speed has the opposite effect, and reduces the generating efficiency of wind-driven generator.
In prior art, the blade of usual wind-driven generator is made movable, realize blade variable oar function, but in order to ensure that blade keeps optimal attack angle returning to circle in process, in prior art, vertical axis aerogenerator is provided with a pusher structure, but mechanism is complicated, and cost is high, also greatly consume the energy of wind, thus cause power coefficient to be had a greatly reduced quality; Another kind of vertical axis windmill of the prior art adopts restriction nail that blade oscillating is limited in the reasonable angle of attack, but easily clash between described restriction nail and blade, under long-term, periodic strong impaction, be easy to damaged blade, affect the working life of wind-driven generator.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of blade of vertical axis wind turbine anti-collision equipment, for deficiency of the prior art, under the prerequisite not affecting wind turbine power generation efficiency, a kind of anti-collision equipment is designed between wheel arm and blade, and be connected with wheel arm vertical rod, by the sphere of activities of crashproof block restriction blade of wind-driven generator, guarantee that blade has optimal attack angle returning to circle in process, can avoid again clashing between blade and wheel arm simultaneously, thus improve the efficiency of wind-driven generator, extend the working life of blade of wind-driven generator.
For achieving the above object, the technical solution of the utility model is as follows: a kind of blade of vertical axis wind turbine anti-collision equipment, comprise vertical shaft, wheel arm, blade, wheel arm vertical rod, upper leaf-nosed, lower leaf-nosed, wheel arm brace, anti-collision equipment, top board, crashproof block, axis hole, block hole, it is characterized in that:
The vertical shaft of described vertical axis windmill by mounting disc by impeller pivot bush unit, described impeller is fixedly connected with multiple wheel arm around uniform, described wheel arm and the mutual vertical welding of wheel arm vertical rod are fixed, and between described wheel arm and wheel arm vertical rod, oblique weld is fixedly installed wheel arm brace; Two ends up and down of described wheel arm vertical rod, are provided with upper leaf-nosed and lower leaf-nosed, described leaf-nosed and lower leaf-nosed by be fixedly connected with vertical with blade that be spirally connected by bearing flexible connection; The upper leaf-nosed top fixed cover that the upper shaft bearing sleeve of described wheel arm vertical rod connects is connected to anti-collision equipment, described anti-collision equipment is provided with one piece of top board, described top board center is provided with axis hole, the aperture of described axis hole and the diameter matches of wheel arm vertical rod are arranged, and described axis hole is for being socketed in the wheel arm vertical rod of described leaf-nosed top; Described top board dual side-edge vertically extends two pieces of crashproof blocks downwards, and described crashproof block is vertically installed in two sides of described wheel arm, and after touching described wheel arm, acting in opposition in upper leaf-nosed, and then limits and the upper leaf-nosed blade be fixedly connected with; Be provided with block hole below described crashproof block, described block hole is used for being mounted with part so that by described anti-collision equipment screens described leaf-nosed up and down and make it axial restraint.
Two pieces of crashproof blocks on described anti-collision equipment are arranged on two adjacent edges of described top board respectively, the setting in mutually perpendicular direction between two pieces of described crashproof block planes; Width between two described crashproof blocks is greater than the diameter of described wheel arm, therefore, after described crashproof block is positioned in described wheel arm, still there is certain slewing area, and then make the leaf-nosed blade with being fixed in leaf-nosed outside also have the slewing area determined.
The bight, two, front and back of described top board is set to oblique angle shape, so that reduce space resistance when following described leaf-nosed rotation.
Described anti-collision equipment be arranged on described impeller each on leaf-nosed on, the quantity that described anti-collision equipment is arranged is identical with the quantity that blade is arranged.
Working principle of the present utility model is: described blade can around the axis rotation of wheel arm vertical rod, and in impeller turning course, blade is substantially vertical with wheel arm all the time under centrifugal action, automatically adjusts oar by the revolution between wheel arm vertical rod simultaneously; In wind driven generator rotation, blade produces centrifugal force away from gyration center, and wheel arm produces pulling force and balances with it, point-blank, size is identical, and direction is contrary for two power, described leaf-nosed gyration center is just in time positioned in radial alignment, the state that centrifugal force forces blade to keep vertical with wheel arm; Wind energy conversion system rotating speed is higher, and blade centrifugal force is larger, and between blade and wheel arm, plumbness maintenance is better
When wind-driven generator runs well, blade is vertical with wheel arm, and two crashproof blocks of anti-collision equipment are positioned at described wheel arm two side; When wind-force is less, when wind-driven generator is not activated, owing to there is no centrifugal force, the blade of impeller side windward cannot keep vertical with wheel arm, blade rotates around wheel arm vertical rod, and along with the increase of blade rotation angle, blade drives upper leaf-nosed rotation, crashproof block in described leaf-nosed drive anti-collision equipment moves, to anti-collision equipment and described take turns arm contact, be subject to the restriction of crashproof block, now blade no longer rotates, wind-exposuring area is maximum, similar resistance type blade; Impeller with the wind the chord of blade length direction of side and wind facies suitable, wind-exposuring area is minimum; Now wind wheel is beneficial to startup, avoids blade oscillating amplitude greatly to the adverse effect that the startup of wind-driven generator produces simultaneously, or collides with wheel arm, the impact of produce power loss.
Pass through technique scheme, the beneficial effect of technical solutions of the utility model is: under the prerequisite not affecting wind turbine power generation efficiency, fixedly anti-collision equipment is equipped with at wheel arm rod end, two crashproof blocks of described anti-collision equipment are positioned at two side positions of described wheel arm, by the sphere of activities of limited the sphere of activities restriction blade of wind-driven generator, guarantee that blade has optimal attack angle returning to circle in process, can avoid again clashing between blade and wheel arm simultaneously, thus improve the efficiency of wind-driven generator, extend the working life of blade of wind-driven generator, this novel Impact Problems solving blade and wheel arm when the low wind speed of vertical axis windmill starts well, avoid vibration & noise, the pitch simultaneously realizing blade regulates automatically.
