Description

Self-adapting flexible vane rotor
Technical field
The present invention relates to a kind of fluid impact type generator, relate in particular to a kind of generator amature.
Background technique
Along with the appearance of energy crisis and going from bad to worse of environment; green clean energy resource more and more is subjected to the extensive attention of countries in the world; wind energy and trend can especially become the focus of development and use renewable energy sources, and utilizing the generating of wind energy and current is to develop wind energy at present and water can the most effective form.Though it is the real spatter property energy that wind-force and trend can be generated electricity, be subjected to factor restrictions such as disposable input is big, technical requirements is high, capacitation efficient is low, just as the supplementary energy of electric energy, promoting has certain degree of difficulty.Invent a kind of low cost, transducing rotor efficiently, with significant.
The main device that extracts wind energy at present is the rigid blade rotor, and its capacitation coefficient is lower, and it is bigger to start wind speed.Defectives such as blade is processed by rigid materials such as glass fibre reinforced plastics mostly, and blade edge is very thin, also may hurt birds etc. during rotation, and exists noise bigger, and metal is perishable.As disclosed Chinese patent on May 7th, 2003, publication number is CN1415852A, it discloses the high-effect windmill of a kind of flexible blades, comprise base, support, central shaft, interior bracing ring, unofficial biography moving-coil, outer fixing circle, drag-line, interior external wind wheel, universal head, though it can alleviate the weight of self, but mentality of designing and common windmill commonly used do not have great difference, can only be to rotate on the direction of wind.Because fan blade makes for very thin steel plate, thus when work, not only produce very big noise, and also fan blade can corrode, and needs often replacing, increased cost.
The tradition stream generating device adopts water turbine or hydrofoil oscillator device more.Can be divided into two kinds of axial flow hydraulic turbine and Francis turbines by the mounting type water turbine of rotor shaft.These two kinds of water turbine all adopt the rigid blade rotor, and capacitation efficient is lower, become tilt angle control in order to raise the efficiency normal employing blade at present, but complex structure, optimum control scheme is difficult to find out, the R﹠D costs height.The hydrofoil oscillator device is formed by the swing arm and the hydrofoil of PLC control by two, hydrofoil master pendulum arm when different positions is coordinated hydrofoil its corresponding pivot angle, makes hydrofoil obtain maximum lift, extraction water energy as much as possible.This type of device PLC control circuit itself will consume a part of electric energy, and the suffered lift of hydrofoil is definite jointly by a plurality of parameters, and its control procedure is complicated more, and research and development and cost of production are all too high, are unfavorable for applying.
Summary of the invention
Technique effect of the present invention can overcome above-mentioned defective, and a kind of self-adapting flexible vane rotor is provided, and low, the easy care of its cost can be realized higher energy conversion efficiency.
For achieving the above object, the present invention adopts following technological scheme: it comprises central rotating shaft, moving runner, fixed support, interference fit between central rotating shaft and the moving runner, both are by the fixed support fixed limit, two supporting layers perpendicular to central rotating shaft are set on the central rotating shaft at least, fixing rod is set on the same circumference that between the two adjacent supporting layers with the central rotating shaft is the center at interval, connect by flexible blade between the adjacent fixing rod, the plane that flexible blade is formed with respect to two fixing rods that are attached thereto can produce concavo-convex deformation.
The mounting type of flexible blade rotor has two kinds: both can adopt vertical mounting type, and can adopt horizontal mounting type again.Supporting layer can be arranged to different forms: can be to be isometric plectane of center radius or regular polygon plate with the central rotating shaft, also can be perpendicular to central rotating shaft and be that the center is with the isometric radially strut of same intervals angle with the central rotating shaft, for improve strut and central rotating shaft join strength, affixed and supporting layer concentric and be positioned at the flange plate of supporting layer on central rotating shaft, strut is fixed with the link socket that is arranged on the flange plate; Supporting layer and fixing rod are by hinge or be threaded.The angular range that the plane that flexible blade is formed with respect to two fixing rods that are attached thereto can produce concavo-convex deformation is-60 °～60 °; The both sides that are arranged on the flexible blade on the fixing rod are not isometric, and the direction unanimity of flexible blade setting; Adjacent flexible blade is not on same horizontal plane, and the diverse location of each flexible blade in 360 ° of circular movement like this can both the self adaption fluid and change shape at any time.Because of flexible material can only transmit pulling force, the stable form of blade is the arc that forms naturally according to the active force of wind or other fluid, the sail wing just as sailing boat, make full use of the lift effect and the mutual checker acting of drag effect of the sail wing, two kinds of effects are formed hydrokineticly all can to produce the moment identical with the rotor rotation direction with joint efforts, thereby utilizes the fluid energy efficiently.
Because the direction that flexible blade is provided with is with respect to the central rotating shaft unanimity, so the moment direction unanimity of its generation, moment of rotation can not cancel each other out; Flexible blade generally is designed to triangle or trapezoidal etc., can be used alone the flexible blade of shape in device, also can adopt difform blade to combine, the direction that its all flexible blades are provided with is identical, the flexible blade general direction towards change, the direction that central shaft rotates can change thereupon; When the center rotating shaft is longer, a plurality of supporting layers can be set, between two adjacent supporting layers, fixing rod and flexible blade are set,, can the resistance to flexure that fixed support improves whole rotor all be set in the both sides of central rotating shaft for firmly fixing central rotating shaft and moving runner more.
Use for reference the principle that sailing boat utilizes wind energy to advance, the rigid blade of fluid generator is changed into flexible material in light weight, that making is simple, cost is low, flexible blade adopts stuffy and liquid-tight material to make, as high molecular film material, canvas etc., this sail wing formula blade, deformable and adaptive characteristic are that rigid blade can't be realized, thereby can produce the bigger torque of specific rigidity blade, has higher power efficieney, therefore the conversion efficiency height can extensively utilize in fluid fields such as wind energy, trend energy.
