Description
Technical field
The utility model relates to a kind of wind generating unit, particularly relates to the lodicule discharge mechanism in a kind of wind generating unit.
Background technique
Generally adopt fixed slurry apart from wind wheel apparatus at present in the wind power generating set; with automatically controlled servo-system control fan stall; promptly this system makes wind wheel integral body turn to driftage under the excessive situation of wind speed; reduce the lifting surface area that facings the wind; thereby guarantee that the blower fan revolution is no more than the rated revolution of generator, protects generator not damaged.Also avoid simultaneously the damage of blower fan and blower fan pillar, guaranteed the security of operation of wind power generating set.
Though the existing fixed security of operation of having protected wind power generating set apart from wind wheel apparatus of starching, also there is following technical problem in it: existing fixed slurry, complex structure high apart from the wind wheel cost, produce, install, overhaul inconvenience; React insensitive, when the unstable or of short duration rapid wind of wind direction, it can not in time react adjustment, causes wind power generating set to damage easily.
The model utility content
The utility model is exactly in order to solve the problems of the technologies described above, and a kind of wind-driven generator lodicule discharge mechanism is provided, and it is with low cost, and is simple in structure, produces, installs, maintenance is convenient, is quick on the draw, and can effectively guarantee the safety of wind power generating set.
In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solution.
A kind of wind-driven generator lodicule discharge mechanism, structure is as follows: lodicule is connected with wheel hub by the lodicule rotatingshaft, and wheel hub and sliding shaft sleeve are slidingly connected with spline, and sliding shaft sleeve is fastened on the generator input shaft, spring places between spring capping and the wheel hub, and spring housing is outside sliding shaft sleeve; Spring capping is fixed on the sliding shaft sleeve front end; Steering link is arranged between sliding shaft sleeve and the lodicule rotatingshaft.
Described steering link one end is fixed on the spring capping of sliding shaft sleeve front end, and the other end is connected on the lodicule rotatingshaft.
Described steering link one end is fixed on the sliding shaft sleeve, and the other end is connected on the lodicule rotatingshaft.
Advantage of the present utility model and effect are as follows:
The utility model is with low cost, and is simple in structure, and it is convenient to produce, install, overhaul, and is quick on the draw, and can effectively guarantee the safety of wind power generating set, prolongs the working life of generator and blower fan.
Description of drawings
Fig. 1 is the structural representation of the utility model wind-driven generator lodicule discharge mechanism.
Among the figure, 1, lodicule; 2, lodicule rotatingshaft; 3, sliding shaft sleeve; 4, spring; 5, spring capping; 6, steering link; 7, wheel hub.
Embodiment
Below description by embodiment the utility model is described in further detail, but this is not to be to restriction of the present utility model, those skilled in the art are according to basic thought of the present utility model, can make various modifications or improvement, but only otherwise break away from basic thought of the present utility model, all within scope of the present utility model.
As shown in Figure 1, the structure of the utility model wind-driven generator lodicule discharge mechanism is as follows: lodicule 1 is connected with wheel hub 7 by lodicule rotatingshaft 2, wheel hub 7 and sliding shaft sleeve 3 are slidingly connected with spline, sliding shaft sleeve 3 is fastened on the generator input shaft, spring 4 places between spring capping 5 and the wheel hub 7, and spring 4 is enclosed within outside the sliding shaft sleeve 3; Spring capping 5 is fixed on sliding shaft sleeve 3 front ends; Steering link 6 is arranged between sliding shaft sleeve 3 and the lodicule rotatingshaft 2.
Described steering link 6 one ends are fixed on the spring capping 5 of sliding shaft sleeve 3 front ends, and the other end is connected on the lodicule rotatingshaft 2.
Described steering link 6 one ends are fixed on the sliding shaft sleeve 3, and the other end is connected on the lodicule rotatingshaft 2.
Working principle of the present utility model is as follows: the mechanics principle that the utility model utilizes, adopted the wheel hub straight line motion to drive lodicule and done yaw motion.When wind speed surpasses the design speed per hour, the stressed power of wheel hub greater than the wheel hub retaining spring, the wheel hub that connects lodicule promptly slides on sliding axle, do yaw motion and there is steering link (the lodicule rotatingshaft is established with the wheel hub joint in the lodicule bottom, can make lodicule do 360 ° of rotations) so just to drive lodicule between wheel hub and the lodicule.The crow flight distance that wheel hub slides is long more, the angle of lodicule deflection is big more, owing to having changed the angle of collecting folk songs, lodicule reduced the area of collecting folk songs like this, make the lodicule rotational velocity reduce, thereby realized that blower fan turns round in the design revolution, guaranteed that generator and blower fan are not damaged, prolonged life of generator, effectively guaranteed the safety of generator.The utility model is with low cost, and is simple in structure, and it is convenient to produce, install, overhaul, and is quick on the draw, and can effectively guarantee the safety of wind power generating set, prolongs the working life of generator and blower fan.
