Abstract
The utility model discloses a blade for wind generating set, it includes blade body, reinforcing module resetting means, blade leading edge reinforcing module, trailing edge reinforcing module, and reinforcing module resetting means sets up in the inside at blade body middle part, and reinforcing module resetting means's aggregate unit's one end and the linkage of blade leading edge reinforcing module are connected, and reinforcing module resetting means's aggregate unit's the other end and the linkage of trailing edge reinforcing module are connected. The utility model discloses this internally sets up a reinforcing module resetting means at blade for wind generating set to respectively connect blade leading edge reinforcing module and trailing edge reinforcing module around the blade, can increase the blade for wind generating set chord length when wind speed is lower, thereby improve the ability that moment of torsion and wind energy were caught to the impeller. Just the utility model discloses simple structure is convenient for manufacture, and is effectual, is suitable for and uses on wind generating set.
Description
Technical field
This utility model relates to wind-driven generator field, particularly relates to a kind of wind generator set blade。
Background technology
The blade of wind power generating set is after mould is determined, its profile can not change。When wind power generating set is in relatively low wind speeds, owing to deviateing far away blade optimal design state so that impeller moment of torsion and power output are greatly reduced。At present, being generally utilized in trailing edge increases an attachment device, and when wind speed is relatively low, attachment device stretches out blade body, increases the chord length of blade thus obtaining high torque。This attachment device needs to adopt active control strategies, and structure is complicated, and needs additionaling power。
Utility model content
The purpose of this utility model is in that to overcome disadvantages described above, it is provided that a kind of simple in construction is without the wind generator set blade of additionaling power。
This utility model solves the technical scheme of above-mentioned technical problem: a kind of wind generator set blade, it includes blade body, also include strengthening module resets device, blade inlet edge strengthens module, trailing edge strengthens module, described enhancing module resets device includes resetting means and linkage, described enhancing module resets device is arranged on the inside in the middle part of blade body, one end of the linkage of described enhancing module resets device and blade inlet edge strengthen module and are connected, the other end of the linkage of described enhancing module resets device and trailing edge strengthen module and are connected, when wind speed is less than or equal to the setting value E1 of resetting means, described enhancing module resets device is in open configuration, now blade inlet edge enhancing module and trailing edge enhancing module stretch out blade body, when wind speed is more than the setting value E2 of resetting means, described enhancing module resets device is in compressive state, now blade inlet edge enhancing module and trailing edge enhancing module are close to blade body, when wind speed is between the setting value E1 and the setting value E2 of resetting means of resetting means, what the stress size according to wind speed and resetting means determined linkage opens size。
In above-mentioned wind generator set blade, when enhancing module resets device is in compressive state, blade inlet edge strengthens module, trailing edge strengthens module and blade body forms a complete blade shape, reaches optimal design。
In above-mentioned wind generator set blade, it is consistent with blade body front end profile that described blade inlet edge strengthens module rear end, can fit tightly with blade body leading edge during contraction。
In above-mentioned wind generator set blade, it is consistent with blade body rear end profile that described trailing edge strengthens module front end, can fit tightly with blade body trailing edge during contraction。
Of the present utility model have the technical effect that wind generator set blade this internal arrange one strengthen module resets device, and each blade inlet edge that connects strengthens module and trailing edge enhancing module after in front of the blade, wind generator set blade chord length can be increased when wind speed is relatively low, thus improving impeller to catch the ability of moment of torsion and wind energy。And this utility model simple in construction, it is simple to manufacture, effective, be suitable to use in wind power generating set。
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described。
With reference to accompanying drawing, a kind of wind generator set blade, it includes blade body 1, also include strengthening module resets device 2, blade inlet edge strengthens module 3, trailing edge strengthens module 4, described enhancing module resets device 2 includes resetting means and linkage, described enhancing module resets device 2 is arranged on the inside in the middle part of blade body 1, one end of the linkage of described enhancing module resets device 2 and blade inlet edge strengthen module 3 and are connected, the other end of the linkage of described enhancing module resets device 2 and trailing edge strengthen module 4 and are connected, when wind speed is less than or equal to the setting value E1 of resetting means, described enhancing module resets device 2 is in open configuration, now blade inlet edge enhancing module 3 and trailing edge enhancing module 4 stretch out blade body 1, when wind speed is more than the setting value E2 of resetting means, described enhancing module resets device 2 is in compressive state, now blade inlet edge enhancing module 3 and trailing edge enhancing module 4 are close to blade body 1, when wind speed is between the setting value E1 and the setting value E2 of resetting means of resetting means, what the stress size according to wind speed and resetting means determined linkage opens size, when enhancing module resets device 2 is in compressive state, blade inlet edge strengthens module 3, trailing edge strengthens module 4 and blade body 1 forms a complete blade shape, reach optimal design, it is consistent with blade body 1 front end profile that described blade inlet edge strengthens module 3 rear end, can fit tightly with blade body 1 leading edge during contraction, it is consistent with blade body 1 rear end profile that described trailing edge strengthens module 4 front end, can fit tightly with blade body 1 trailing edge during contraction。
This utility model strengthens module resets device and front and rear edge strengthens module and is not limited in shown in embodiment, as long as meeting this utility model principle, all at protection domain of the present utility model。
