Abstract
The present invention relates to a wind-driven power generator, belonging to the field of wind energy application technology. It is formed from the following several portions: wind blade, wind blade shaft, power shaft, direction controller, clutch, power generator and upright column. Said invention also provides the connection mode of above-mentioned all the portions, and also provides the working principle of said wind-driven power generator and its operation method.
Description
Technical field
The present invention relates to the wind energy application, especially wind-driven generator.
Background technique
At present, the wind-driven generator of extensive use is a horizontal axis wind-driven generator, and the fabricating cost height especially to large-scale wind driven generator, needs special erection unit, and expense is big.Application number is 200510071200.7 1 kinds of wind-driven generators, by driver rotor and stator is produced and relatively moves, and causes electromagnetic induction to change and carries out speed governing, and structure is also rather complicated, poor reliability.
Summary of the invention
For overcoming existing vertical shaft wind power generator structure complexity, the problem of poor reliability the invention provides a kind of wind-driven generator, and is not only simple in structure, and low cost of manufacture is easy for installation, and good reliability.
The technical solution adopted for the present invention to solve the technical problems is; Be made up of fan blade, blade shaft, line shaft, rudder, clutch, generator, column, blade shaft and line shaft are vertical mutually and be connected, and two coaxial fan blade faces are vertical mutually, and rudder fan blade perpendicular to the ground has the part interference that overlaps.Interior cover is arranged in the blade shaft, by Xiao two-semiaxle is linked to each other, guide groove is arranged on the semiaxis, two-semiaxle also passes through Xiao Xianglian by spring.Be connected with free wheel device and unidirectional ratchet on the line shaft, wind promotes fan blade face perpendicular to the ground and rotates acting around line shaft, coaxial another fan blade face place upwind is parallel with wind direction, when fan blade perpendicular to the ground forwards the rudder place to, interfere owing to overlap, it is parallel to the ground that the fan blade face is rotated to, and enters district against the wind, the fan blade face of the coaxial the other end is then perpendicular to the ground, enters working area with the wind.So go round and begin again.Free wheel device makes wind-power electricity generation function No Load Start, drives driven disc during to certain rotating speed, thereby makes generator work, and unidirectional ratchet guarantees that wind-driven generator only makees folk prescription to rotation.Fan blade two-semiaxle, guide groove and the spring that is connected can make wind-driven generator regulate rotating speed voluntarily, and when overstepping the extreme limit rotating speed, power-driven generator leaf moves outward and breaks away from the rudder interference region, and wind-driven generator is stopped, and plays the overspeed protection effect.
The invention has the beneficial effects as follows: simple in structure, have the function of No Load Start, speed governing voluntarily, unidirectional rotation, overspeed protection simultaneously, and low cost of manufacture, easy for installation, use reliable.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a construction profile schematic representation of the present invention.
Fig. 2 is an embodiment of the invention main body structure diagrammatic cross-sectional view.
Fig. 3 is the sectional view of Fig. 2 " I-I ".
Among the figure, 1. fan blade, 2. blade shaft, 3. line shaft, 4. rudder, 5. column, 6. in cover, 7. Xiao, 8. spring, 9. inclined guide groove, 10. straight guide groove, 11. Xiao, 12. semiaxis, 13. bearing, 14. shaft-cups, 15. lids, 16. bearings, 17. bolt, 18. balls, 19. bearings, 20. driven discs, 21. free wheel device, 22. ratchets, 23. speed changers, 24. generators.
Embodiment
In Fig. 1 and Fig. 2, two fan blades (1) place blade shaft (2) both sides respectively, blade shaft (2) is vertical with line shaft (3) and be connected, rudder (4) is connected with column (5) by ball (18) and bolt (17), rudder (4) upper blade is interfered with having perpendicular to the fan blade (1) on ground to overlap, to realize fan blade (1) turning to when transferring to against the wind, make its fan blade face parallel with wind direction, make coaxial opposite side fan blade (1) transfer positive facining the wind to simultaneously.Have interior cover (6) by Xiao (11) two-semiaxle (12) to be linked to each other in the blade shaft (2), two-semiaxle (12) is also continuous by Xiao (7) by spring (8), makes the termination contact simultaneously.Semiaxis has guide groove on (12), and guide groove has straight guide groove (10) and inclined guide groove (9).When wind energy conversion system started, coaxial two fan blades (1) were vertical mutually, the wind-exposuring area maximum of windward side, the blowing area minimum of adverse wind face.After the rotation, two fan blades (1) move outside under centrifugal action in the speed range of regulation, acting moment strengthens, when the wind energy conversion system rotating speed surpasses rated speed, semiaxis (12) makes Xiao (11) enter inclined guide groove (9) from straight guide groove (10) under centrifugal action, causes coaxial both sides fan blade not perpendicular, and the wind-exposuring area of fan blade (1) windward side is reduced, driving moment descends, and makes wind energy conversion system return to rated speed.If wind-force is especially big, when the wind energy conversion system rotating speed overstepped the extreme limit, then two fan blades (1) and semiaxis (12) moved the interference region that breaks away from rudder (4) outside under centrifugal action, and then fan blade (1) stops operating.Blade shaft (2) is connected with interior cover (6) and semiaxis (12) through bearing (13) by shaft-cup (14).There are dustproof and rainproof lid (15) in bearing (16) top, line shaft (3) is connected with column (5) through bearing (16), bearing (19), clutch is free wheel device (21), between clutch that links to each other with line shaft (3) and the driven disc (20) unidirectional ratchet (22) is arranged.Driven disc (20) drives generator (24) through speed changer (23).Free wheel device (21) makes wind-power electricity generation function No Load Start, drives driven disc (20) during to certain rotating speed, thereby makes generator work, and unidirectional ratchet (22) guarantees that wind-driven generator only makees folk prescription to rotation.
