Description

Self-regualting type wind-driven generator impeller

Affiliated technical field

The present invention relates to a kind of wind-driven generator impeller, especially a kind of self-regualting type wind-driven generator impeller.

Background technique

At present, the horizontal axis wind-driven generator impeller has the oar of deciding formula and variable pitch type, deciding the pitch-control type wind power generator impeller immobilizes because of its blade angle that facings the wind, so starting wind speed requires big, when meeting strong wind for preventing that the wind-driven generator driving from burning out wind-driven generator, also arrestment mechanism will be set, Wind Power Utilization efficient is low.The variable pitch type wind driven generator impeller can change the blade angle that facings the wind, and improves wind energy utilization, but become oar one cover blade pitch device will be set, and makes the wind-driven generator structure complexity strengthen manufacture cost again.

Summary of the invention

Goal of the invention: decide the pitch-control type wind power generator impeller to start wind speed big for overcoming, anti-strong wind driving arrestment mechanism of configuration and variable pitch type wind driven generator impeller will be provided with blade pitch device again, make the wind-driven generator structure complexity, strengthen deficiencies such as manufacture cost, provide a kind of startup wind speed low, can change according to wind speed and wheel speed and adjust the blade angle that facings the wind, self-regualting type wind-driven generator impeller voluntarily with anti-strong wind driving function.

Invention technological scheme: self-regualting type wind-driven generator impeller, the impeller plate is arranged on impeller shaft, impeller plate circumference is spared the some sharf connecting sleeves of cloth, the location sliding-groove is arranged on the sharf connecting sleeve, sharf one end has the location sliding pin, the fixedly connected blade of the other end, sharf one end inserts in the sharf connecting sleeve and can rotate, the location sliding pin places the location sliding-groove to be fixed on the sharf and can rotate at the location sliding-groove with sharf and slide, with axially locating and the radially rotation angle of control sharf in the sharf connecting sleeve, reach the control blade angle that facings the wind and change purpose, suit one torque spring on the sharf connecting sleeve, torque spring one end is fixed on the sharf connecting sleeve, and the other end is stuck on the blade, and the effect of torque spring makes blade be in the minimum position, angle that facings the wind when being startup.

The described angle that facings the wind is the angle between wind direction and the blade windward side.

Blade is that plane blade part and outer edge are that lift-type blade part two-part blade is crossed as the integral blade that several angle is formed by root, two partly blade interconnection angles make the outer edge lift-type partly blade facing the wind angle less than the angle of facining the wind of root planar section blade, the outer edge lift-type partly blade area greater than root plane blade area partly.

The link position of sharf and blade by sharf and on blade the elongation line both sides be divided into rotation direction forwardly part blade area less than rotation direction in the rear section blade area.

Beneficial effect:

1, the startup wind speed is low, and moment of torsion is big, can make full use of low wind speed wind energy resources.

2, can adjust the angle that facings the wind of blade according to the wind speed that changes voluntarily, make blade be in the best angle work of facining the wind all the time, improve the wind energy resources utilization ratio.

3, impeller itself has anti-strong wind driving function, saves anti-strong wind driving arrestment mechanism.

Embodiment

Self-regualting type wind-driven generator impeller, the impeller plate 2 is arranged on impeller shaft 1, the impeller plate 2 circumference are spared the some sharf connecting sleeves 3 of cloth, location sliding-groove 4 is arranged on the sharf connecting sleeve 3, sharf 5 one ends have location sliding pin 6, the fixedly connected blade 7 of the other end, sharf 5 one ends insert in the sharf connecting sleeve 3 and can rotate, location sliding pin 6 places location sliding-groove 4 to be fixed on the sharf 5 and can rotate at location sliding-groove 4 with sharf 5 and slide, with axially locating and the radially rotation angle of control sharf 5 in sharf connecting sleeve 3, reach control blade 7 and change purpose in the angle down with the wind, suit one torque spring 8 on sharf connecting sleeve 3, torque spring 8 one ends are fixed on the sharf connecting sleeve 3, and the other end is stuck on the blade 7, and the effect of torque spring 8 makes blade 7 be in the minimum position, angle that facings the wind when being startup.

Blade 7 is that plane blade part and outer edge are that lift-type blade part two-part blade is crossed as the integral blade 7 that several angle is formed by root, two partly blade interconnection angles make the outer edge lift-type partly blade facing the wind angle less than the angle of facining the wind of root planar section blade, the outer edge lift-type partly blade area greater than root plane blade area partly.

The link position of sharf 5 and blade 7 by sharf 5 and on blade 7 the elongation line both sides be divided into rotation direction forwardly part blade area less than rotation direction in the rear section blade area.

When self-regualting type wind-driven generator impeller starts, since sharf 5 on the blade 7 and elongation line both sides rotation direction thereof in the back partly blade area greater than rotation direction part blade area forwardly, rotation direction in the back partly the thrust of blade wind-engaging greater than the rotation direction thrust of part blade forwardly, under torque spring 8 and wind-force promotion, making blade 7 serves as that axle drive sharf 5 rotates in blade connecting sleeve 3 with sharf 5 and its at elongation line on the blade 7, make blade 7 angle that facings the wind be in the location sliding-groove 4 on the location sliding pin 6 and blade connecting sleeve 3 sets on the sharf 5 the minimum position, angle that facings the wind, this moment, blade 7 root planes part blade and outer rim lift-type part blade all were in the minimum separately angle that facings the wind that sets, low wind speed under promoting, wind-force can both produce the power that makes wheel rotation, so just can make impeller start.

Start the back along with wheel speed is accelerated, the minimum that the Driving force of torque spring 8 and wind makes blade 7 will keep the setting angle that facings the wind, and along with wheel speed is accelerated, blade 7 back sides are subjected to resistance of air will promote blade 7 angle that facings the wind to strengthen, so the angle that facings the wind of blade 7 will be subjected to balance between the resistance of air at the Driving force and blade 7 back sides of blade 7 windward side wind-engagings, adjust to voluntarily under the angle of facining the wind that adapts to most balance between the two and work, make impeller can under instantaneous value, utilize wind energy resources to greatest extent.

When wind speed continues to strengthen, when wheel speed continued to accelerate, blade 7 back side resistance of air also strengthened, and made blade 7 outer edge lift-type blades partly be in the angle that facings the wind more greatly, and blade 7 root plane blades partly are in when parallel with sense of rotation, and impeller is in the fastest rotating speed and optimum Working.

When meeting strong wind, make wheel speed fast, blade 7 back side resistance of air are bigger, make the blade 7 outer edge lift-type blades angle that partly facings the wind very big, and blade 7 root plane blades partly are in contrast the direction angle that facings the wind, make on the blade 7 plane partly blade be subjected to opposite direction power, therefore the slow impeller hypervelocity of resistance rotation, impeller speed limit is fixed within the maximum speed of setting, avoid wind-driven generator to produce the driving phenomenon, simultaneously also normal stable operation when strong wind.
