Abstract

The utility model relates to a manual variable pitch mechanism of a wind driven generator. The manual variable pitch mechanism at least comprises a vane, a vane rotating shaft, a linkage rod, a linkage plate and a wind wheel flange. The vane is installed on the vane rotating shaft. The vane rotating shaft is installed on the wind wheel flange. The linkage rod is fixedly arranged on the vane rotating shaft and hinged to the linkage plate through a linkage pin. A hand brake type variable pitch mechanism is formed by a steel wire rope guide sleeve, a long guide sleeve of a steel wire rope, and a spring sleeved on the long guide sleeve of the steel wire rope. A pressure spring sleeved on a spring pin and one end, sleeved on the long guide sleeve of the steel wire rope, of the spring abut against a wind wheel flange rib plate to generate initial torque on the vane. The linkage plate is sleeved on a shaft sleeve of the wind wheel flange through a deep groove ball bearing with dustproof covers on two sides. The wind wheel flange is arranged on a main shaft of a generator set through the shaft sleeve. The manual variable pitch mechanism has the advantages of being simple in structure, good in stability and low in cost.

Description

Background technique
Under the shortage day by day of current non-renewable energy resources, weather sharply changes, environment goes from bad to worse global context, wind energy is subjected to various countries as renewable, the environmental protection energy and shows great attention to, and also will be the main direction of the current utilization of new energy resources of China.In wind-power electricity generation, because natural wind speed is changeable, in order to improve utilization ratio of wind energy, wind-driven generator often adopts and becomes the oar technology, pass through to adjust the angle of fan blade and the angle of attack when meeting strong wind even typhoon, reach the stable output of generated output, finally improved generating efficiency and the quality of power supply of whole wind force generating system.
The pitch-controlled system of paddle changing wind power generator employing at present mainly contains hydraulic pressure and electronic.Hydraulic vane change device, its drive mechanism relative complex, leakage of oil, bite happen occasionally, and hydraulic transmission part is bigger in the control accuracy difference in summer and winter.The electric variable pitch device, its manufacture cost height, maintenance are inconvenient, and wind-driven generator is after operation a period of time, and inner lubricant grease can loss, needs to add lubricant grease, has increased the maintenance difficulty of wind-driven generator.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of manual blade pitch device of wind-driven generator is provided, and simple in structure and easy to maintenance.
In order to solve described technical problem, the utility model provides a kind of manual blade pitch device of wind-driven generator, at least comprise blade, blade rotor, linkage rod, the interlock dish, the wind wheel flange, described blade is installed on the blade rotor, blade rotor is installed on the wind wheel flange, linkage rod is fixedly mounted on the blade rotor, be hinged by set bar and interlock dish, wherein, by the wire rope guide pin bushing, the long guide pin bushing of wire rope and the spring that is enclosed within on the long guide pin bushing of wire rope constitute a hand brake type blade pitch device, an end that is enclosed within the stage clip of spring pin and is enclosed within the spring of the long guide pin bushing of wire rope by described linkage rod is against on the wind wheel flange gusset, blade is produced initial torque, described interlock dish is enclosed within on the axle sleeve of wind wheel flange by the deep groove ball bearing of two sides band dust cover, and described wind wheel flange is assemblied on the main shaft of generator set by axle sleeve.The utility model has adopted the manual blade pitch device of similar bicycle parking brake formula, and is simple in structure, and easy to maintenance.
On the such scheme basis, the position that is hinged of described blade rotor and interlock dish is provided with self-lubricating plain radial bearing, and described linkage rod is hinged by set bar and self-lubricating plain radial bearing and interlock dish.Self-lubricating plain radial bearing have wear resistance good, need not to add characteristics such as lubricant grease, damping.
The utlity model has simple in structure, good stability and the low characteristics of cost, by stage clip and spring the opplied moment of blade is controlled the vane propeller-changing angle, it is more steady to make impeller become oar, reduces the vane propeller-changing frequency, can effectively improve efficient, Security and the stability of wind-driven generator; And adopt self-lubricating plain radial bearing have wear resistance good, need not to add characteristics such as lubricant grease, damping, thereby improve wind-driven generator service life and reduce the maintenance difficulty.

Embodiment
Shown in Fig. 1 structural representation of the present utility model and Fig. 2 side of the present utility model general bureau broken section structural representation, a kind of manual blade pitch device of wind-driven generator, at least comprise blade 1, blade rotor 2, linkage rod 3, interlock dish 7, wind wheel flange 6, described blade 1 is installed on the blade rotor 2, blade rotor 2 is installed on the wind wheel flange 6, linkage rod 3 is fixedly mounted on the blade rotor 2, be hinged by set bar 4 and interlock dish 7, wherein, by wire rope guide pin bushing 11, the long guide pin bushing 13 of wire rope and the spring 12 that is enclosed within on the long guide pin bushing 13 of wire rope constitute a hand brake type blade pitch device, an end that is enclosed within the stage clip 9 of spring pin 8 and is enclosed within the spring 12 of the long guide pin bushing 13 of wire rope is against on wind wheel flange 6 gussets, blade 1 is produced initial torque, described interlock dish 7 is enclosed within on the axle sleeve of wind wheel flange 6 by the deep groove ball bearing of two sides band dust cover, and described wind wheel flange 6 is assemblied on the main shaft 14 of generator set 10 by axle sleeve.
As shown in Figure 2, described blade rotor 2 is provided with self-lubricating plain radial bearing 5 with the position that is hinged of interlock dish 7, and described linkage rod 3 is hinged with interlock dish 7 by set bar 4 and self-lubricating plain radial bearing 5.Self-lubricating plain radial bearing 5 has damping, need not fatten, advantage such as wear-resisting.
