Abstract
The utility model relates to a rotor wing vertical shaft wind motor capable of self-adjusting blade pitch, belonging to the field of wind-driven generators. The utility model comprises a tower frame, a motor, a rotor arm, and blades. The utility model is characterized in that the motor is arranged on the top of the tower frame; one end of the rotor arm is connected with the main shaft of the motor and the other end is hinged with blades. Two horizontal loops are arranged in the center of the blades and the horizontal loop on the rotor arm is hinged with the horizontal loop on the blade by a pin shaft. The utility model is also characterized in that the blade is capable of self-adjusting the blade pitch and constantly keeping the best upwind angle. The utility model has the advantages of high generation efficiency, simple structure, low cost, etc.
Description
The utility model relates to technical field of wind power generator, particularly a kind of paddle distance self-adjusting rotor upright shaft wind motor.
The pitch control system of common rotor upright shaft wind motor is made up of push rod, center cams, blade and weathercock.Its structure is that weathercock makes cam static relatively, and push rod one end is connected with cam, and an end is connected with fan blade.When wind wheel rotates, because action of cam, push rod is done cyclical movement, promote blade and make periodic variation pitch established angle, the blade of this structure just rotates according to mechanical mechanism controls, thereby can't ensure maintenance best surface of contact (angle) between blade and air-flow, and there is complex structure in the pitch control system of this wind energy conversion system, the cost height, wind energy consumption is big, can't be to defectives such as large scale developments.
Invention order of the present utility model provides a kind of blade and adjust the pitch established angle arbitrarily in wind wheel rotates, and keeps the best angle that facings the wind at random, and paddle distance self-adjusting rotor upright shaft wind motor simple in structure, that efficient is high, cost is low.
Foregoing invention purpose of the present utility model realizes by following technical proposals:
A kind of paddle distance self-adjusting rotor upright shaft wind motor that comprises pylon, motor, wheel arm and blade is characterized in that electric machine on the pylon top, and electric machine main shaft is connected with an end of wheel arm, and the other end and the blade of wheel arm are hinged.
Described blade is hinged with wheel arm one end, and purpose is to realize blade automatic pitch established angle of adjusting in wind wheel rotates, and reaches the designing requirement at the best angle that facings the wind.When wind wheel rotates, the wheel arm is static relatively under action of centrifugal force for blade, blade tries hard to turn to down wind (relatively rotating wind direction) again under the effect of wind-force simultaneously, centrifugal force and wind-force act on blade simultaneously, make blade and wind direction form an angle, remain the best angle that facings the wind, produce maximum thrust, improve generating efficiency.When wind direction was relatively stable, wind wheel rotated a circle, and blade is done cyclically-varying, and during when the positive down wind of blade or against the wind to 2, the angle that facings the wind is zero, and all there is angle generation down with the wind other any positions, thereby all have thrust to produce.
In order to reduce the wind energy loss, wheel arm one end and blade are hinged the position and are positioned at the blade center, be connected with blade steadily in order to improve the wheel arm, the blade center is equipped with horizontal loops, horizontal loops and the horizontal loops on the blade on the wheel arm are hinged by a bearing pin, and the horizontal number of rings on the horizontal number of rings that the blade center is equipped with, the wheel arm is preferably 2～5.
Described arm one end of taking turns is connected with electric machine main shaft, save complicated pitch control mechanism, thereby be expected lengthening wheel arm and blade, made high-power wind mill, the development and use wind energy has been created condition, the purpose of design that implementation structure is simple, cost is low simultaneously in order to maximize.
A kind of paddle distance self-adjusting rotor upright shaft wind motor of the utility model structure, have blade and in wind wheel rotates, adjust the pitch established angle automatically, remain the best angle that facings the wind, the generating efficiency height, and simple in structure, cost is low and advantage such as the development and use that are particularly suitable for maximizing.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
