Abstract
The utility model relates to the improvement of a wind power generator structure, particularly a stageless speed changing wind power generator. The utility model provides a wind power generator which ensures the work under the condition of a down-wind type (wind blows to oar blades from a machine room) and realizes stageless speed change. The utility model comprises a supporting post and a pull rope, wherein a machine room provided with oar blades is fixed to the supporting post through a supporting seat. The utility model has the essential structure that a shaft of the oar blades is fixed to a shaft sleeve of a supporting frame of the machine room shell body, and the other end of the shaft sleeve is connected with the shell body through a hydraulic cylinder, and a driving bevel gear at the shaft end is engaged with a bevel gear which is engaged with a driven bevel gear on a shaft of an oil pump; a hydraulic motor is separately connected with the shaft the oil pump and a generator shaft, and the supporting frame on the side part of the bevel gear is provided with a ratchet pawl engaged with the bevel gear.
Description
Technical field:
The utility model relates to the improvement of wind-driven generator structure.
Background technique:
Present wind-driven generator all is to adopt the windward formula, and promptly wind blows to the direction of cabin from blade.Because wind direction is indefinite, when wind is not the windward formula, just can not normal power generation; For this reason, just must the supporting rotating machinery that cabin is arranged.
In addition, general wind-driven generator all is through the gearbox speed-raising, reaches the rotating speed of generator.But because the wind speed instability causes the generator speed shakiness; Therefore, need certain rotating speed equipment of adjusting, most of now feather method that adopts; But its motion component require to make the precision height, and often maintenance.
The model utility content:
The utility model is exactly at the problems referred to above, provides a kind of and guarantees for working the wind-driven generator of continuously variable under leeward formula (being that wind blows to blade from the cabin) condition.
The utility model adopts following technological scheme: the utility model comprises pillar, stay cord, cabin with blade is fixed on the pillar by bearing, the axle of its structure outline blade is fixed on the axle sleeve of support of cabin housing, the other end of axle sleeve links to each other with housing by oil hydraulic cylinder, the driving bevel gear of axle head meshes with umbrella gear, umbrella gear is gone up passive umbrella gear engagement with the axle of oil pump, and the axle of the same respectively oil pump of oil hydraulic motor, generator links to each other; The support of umbrella gear side is provided with the ratchet with the umbrella gear engagement.
The beneficial effects of the utility model:
1. can guarantee to work under the leeward formula condition:
Because the support of umbrella gear of the present utility model side is provided with the ratchet with the umbrella gear engagement, can only be with regard to the may command blade for working under the leeward formula condition, ratchet just makes the umbrella gear stall under the windward condition, then, wind direction can blow to leeward formula condition to cabin slightly partially, just guarantees to work under the leeward formula condition;
2. continuously variable:
The utility model has adopted oil hydraulic motor to replace the existing mechanical gear, just can utilize oil hydraulic motor to carry out stepless speed regulation, and the electricity of having removed existing adjustment blade from is to equipment; Especially the piston of oil hydraulic pump can be subjected to the size of wind-force with blade, changes and elongates or shortens at leeward formula condition blade rotation angle;
3. the generator constant rotational speed is constant:
Owing to adopt oil hydraulic motor, oil hydraulic cylinder stepless change; And speed adjustable range is wide, can make generator keep constant revolution; Saved the part electrical apparatus control equipment;
4. simple in structure:
Member of the present utility model is few and simple, is easy to make, and is easy to popularize.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of cabin of the present utility model;
Fig. 3 is the structural representation of oil hydraulic motor of the present utility model.
Embodiment:
The utility model comprises pillar 2, stay cord 1, cabin 5 with blade 3 is fixed on the pillar 2 by bearing 4, the axle 9 of blade 3 is fixed on the axle sleeve 8 of support 11 of cabin 5 housings 20, the other end of axle sleeve 8 links to each other with housing 20 by oil hydraulic cylinder 6, the driving bevel gear 10 of axle 9 ends is with umbrella gear 12 engagements, passive umbrella gear 13 engagements on the axle 14 of umbrella gear 12 with oil pump 15, oil hydraulic motor 16 links to each other with the axle 18 of oil pump 15, generator 19 respectively; The support 11 of umbrella gear 12 sides is provided with the ratchet 7 with umbrella gear 12 engagements.
Housing 21 that also can oil hydraulic motor 16 is provided with oil hydraulic cylinder 17, can change into oil drain quantity, reconciles the rotating speed of generator 19.
Below in conjunction with a description of drawings course of action of the present utility model:
Under the condition of leeward formula, driving bevel gear 10, umbrella gear 12, passive umbrella gear 13 that blade 3 is driven on the blade 3 by the thrust of wind-force rotate, and the axle 14 that passive umbrella gear 13 drives oil pump 15 rotates; Oil pump 15 drives oil hydraulic motor 16 and rotates, and oil hydraulic motor 16 drives generator 19 generatings.
