Abstract
The utility model relates to an automatic cable-releasing device of small wind generator, in which the twisting off of cables due to too large shaft rotational angle along with the changes of wind direction can be avoided. The automatic cable-releasing device of small wind generator of the utility model comprises a riser and a generator installed on the upper end of the riser. The cable is connected to the generator through the riser, which is characterized in that the riser is provided with a steering shaft through a bearing, and the generator is installed and fixed on the upper end of the steering shaft. The cable passing through the steering shaft is connected to the generator. The steering shaft is jacketed with a torsion spring in which one end is fixed and connected on the wall of the riser, and the other end is connected and fixed on the steering shaft. The technical scheme is simple in structure with low production costs. Therefore, the phenomenon of the twisting off of cables can be effectively avoided.
Description
Technical field
The utility model relates to a kind of automatic cable-releasing equipment for small wind power generator.Can avoid owing to wind direction changes the excessive cable that twists off of the rotating shaft anglec of rotation.
Technology is quiet and secluded
Small-sized wind power generator is because many-sided excellent specific property has obtained application widely.The key technology at the performance of small generators, speed adjusting gear and each position is gradually improved now, has the automatic cable-releasing aspect only, does not also have mature technique.In natural environment, because the direction of wind-force often changes, in order to make full use of wind energy, the wind wheel of wind-driven generator is usually designed to can regulate direction down with the wind automatically, if and when not having automatic cable-releasing equipment, wind-driven generator often rotates that the accumulation anglec of rotation of generation is excessive just might to twist off cable.The automatic cable-releasing technology that large-scale wind driven generator uses is not because complex structure, with high costs is suitable for cheap small-sized wind power generator.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the automatic cable-releasing equipment for small wind power generator that production cost is low.
For achieving the above object, the utility model adopts following technical scheme:
Automatic cable-releasing equipment for small wind power generator described in the utility model comprises standpipe, is installed in the generator of standpipe upper end, cable passes standpipe and is connected with generator, it is characterized in that: by Bearing Installation steering spindle is arranged in the standpipe, generator is fixedly mounted on the upper end of steering spindle, cable passes steering spindle and is connected with generator, be set with torsion spring on the steering spindle, an end of torsion spring is fixedly connected on the standpipe tube wall, and the other end is fixedly connected on the steering spindle.
Install for the ease of producing, the inwall of standpipe is installed with the standpipe retainer ring, is installed with the steering spindle retainer ring on the steering spindle, and an end of torsion spring is fixedly connected on the standpipe retainer ring, and the other end is fixedly connected on the steering spindle retainer ring.
The technical program is simple in structure, and low production cost can avoid cable to be cut with scissors disconnected phenomenon effectively.
Description of drawings
Accompanying drawing is the partial sectional view of an embodiment of the present utility model.
Specific embodiment
As shown in drawings, automatic cable-releasing equipment for small wind power generator described in the utility model comprises standpipe 1, is installed in the generator 2 of standpipe 1 upper end, by Bearing Installation steering spindle 4 is arranged in the standpipe 1, generator 2 is fixedly mounted on the upper end of steering spindle 4, cable 3 passes steering spindle 4 and is connected with generator 2, be set with torsion spring 5 on the steering spindle 4, the inwall of standpipe 1 is installed with standpipe retainer ring 6, be installed with steering spindle retainer ring 7 on the steering spindle 4, one end of torsion spring 5 is fixedly connected on the standpipe retainer ring 6, and the other end is fixedly connected on the steering spindle retainer ring 7.
Certainly, as another embodiment of the present utility model, also can not set up pipe retainer ring 6 and steering spindle retainer ring 7, and an end of torsion spring 5 directly is fixedly connected on standpipe 1 tube wall, the other end directly is fixedly connected on the steering spindle 4.
When wind direction changed, the elastic force that steering spindle 4 may overcome torsion spring deflected, and (can be designed in 360 degree) under the little situation of deflection angle, and steering spindle 4 is in the indifferent equilibrium state, can be arbitrarily to wind; And in case accumulate steering angle excessive (for example surpass 360 degree), though steering spindle can rotate, in case and wind-force disappears or steering spindle will return when weakening, avoid producing excessive steering angle, twist off cable.
