Abstract
The utility model provides a leaf blade set structure of a vertical wind power generator, which comprises a bearing and a leaf blade. The bearing is sheathed on a tower column, the leaf blade is connected with the bearing, a spring is arranged between the leaf blade and the bearing, one end of the spring is connected with the bearing, and the other end of the spring is connected with the leaf blade. When in ultra strong wind, the elastic deformation of the spring can change the shape of the leaf blade so as to restrain the rotating speed of the power generator from rising.
Description
Technical field
The utility model relates to the wind-driven generator field, especially the vane group structure of the vertical wind power generator of Φ shape blade.
Background technique
At present, wind-driven generator extensively has been present in the middle of people's the production and life with advantages such as its applicability are strong, pollution-free, and still, also there are a lot of problems in wind-driven generator, and these difficult problems all are because natural wind exists many unstability caused.When super large wind, the rotating speed of wind-driven generator is out of hand easily, and the generator of this work that exceeds the quata is easy to cause damage, even can impact to electrical network.For Electrical Discharge Machine can be run well when the super large wind, can pass through the peripheral hardware braking device, by the mode of forcing brake generator speed is descended, the purpose of generator though this kind situation also can accomplish to slow down, its loss ratio to generator is bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of vane group structure of vertical wind power generator, and is not only simple in structure, generator mechanism is not had influence, and the rotating speed that can effectively suppress generator when super large wind rises.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vane group structure of vertical wind power generator comprises the bearing that is enclosed within on the king-post, the blade that is connected with bearing; Be provided with spring between described blade and the bearing, described spring one end is connected with bearing, and the other end is connected with blade.When super large wind, the rotating speed of blade rises, the suffered centrifugal force of blade increases, the spring that has connected blade and bearing is stretched under powerful tension, blade outwards moves, variation has taken place in the shape and the windward side of blade, and the rotating speed of blade is suppressed, thereby arrives the purpose of control generator speed.
As improvement, described spring is provided with protecting jacket outward, and described protecting jacket wraps up described spring.
As improvement, be provided with position-limit mechanism between described blade and the bearing.When super large wind, blade is in high speed rotating, and blade can produce huge centrifugal force, and its pulling force to spring is very strong, probably makes this moment spring that huge elastic strain takes place, even might break spring and cause danger.The setting of position-limit mechanism makes the outset of blade from being restricted, and promptly the collapsing length of spring is restricted, and has effectively avoided the excessively flexible of spring, thereby has protected gen-set not to be damaged.
As further improvement, described position-limit mechanism locating stud, locating stud one end is connected with bearing, and the other end stretches in the blade, flexibly connects with blade.
As further improvement, described position-limit mechanism cable wire, cable wire one end is connected with bearing, and the other end is connected with blade.
As further improvement, described position-limit mechanism is a cylinder arm, and cylinder arm one end is connected with bearing, and the other end is connected with blade.
The beneficial effect that the utility model is compared with prior art brought is:
Utilize spring as the device that changes deformable blade, this structure is not only simple, generator mechanism is not had influence, and the rotating speed that can effectively suppress generator when super large wind rises.
Description of drawings
Fig. 1 is the vertical wind power generator structural representation;
Fig. 2 is the A place enlarged view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, 2, a kind of vane group structure of vertical wind power generator comprises the bearing 4 that is enclosed within on the king-post 2, the blade 1 that is connected with bearing 4.Be provided with spring 3 between described blade 1 and the bearing 4, described spring 3 one ends are connected with bearing 4, and the other end is connected with blade 1, the described spring 3 outer protecting jackets 5 that are provided with, the described spring 3 of described protecting jacket 5 parcels.When strong wind, the rotating speed of blade 1 rises, blade 1 suffered centrifugal force increases, the spring 3 that has connected blade 1 and bearing 4 is stretched under powerful tension, blade 1 outwards moves, variation has taken place in the shape and the windward side of blade 1, and the rotating speed of blade 1 is suppressed, thereby arrives the purpose of control generator 6 rotating speeds.After wind speed decreased, spring 3 shapes are restored, and blade 1 moves to king-post 2 directions, and last blade 1 will reset into best windward side state.
In addition, when super large wind, blade is in high speed rotating, and blade can produce huge centrifugal force, and its pulling force to spring is very strong, probably makes this moment spring that huge elastic strain takes place, even might break spring and cause danger.Therefore need be provided with position-limit mechanism between described blade and bearing, the position-limit mechanism of present embodiment is a locating stud 7, and locating stud 7 one ends are connected with bearing, and the other end stretches in the blade 1, flexibly connects with blade 1.The setting of position-limit mechanism makes the outset of blade from being restricted, and promptly the collapsing length of spring is restricted, and has effectively avoided the excessively flexible of spring, thereby has protected gen-set not to be damaged.
Described position-limit mechanism can also be a cable wire, and cable wire one end is connected with bearing, and the other end is connected with blade.Described position-limit mechanism can also be a cylinder arm, and cylinder arm one end is connected with bearing, and the other end is connected with blade.Above-mentioned cable wire or cylinder arm have the effect of restraining spring collapsing length equally.
The utility model utilizes spring as the device that changes deformable blade, and this structure is not only simple, generator mechanism is not had influence, and the rotating speed that can effectively suppress generator when super large wind rises.
