Abstract
The utility model provides a blade that hinders aerogenerator effectively falls, the blade include the casing, the front end of casing be semi -circular structure, the afterbody spur type of casing, the inside hollow structure that is of casing, hollow structure in be provided with the support frame, the support frame setting in hollow structure's the wideest department, the front end of casing be provided with the triangle -shaped boss. The utility model discloses a windward side at the blade sets up triangle -shaped convex structure for the blade is littleer at the aerodynamic drag that the during operation received, and the loss energy is also corresponding less, has obtained showing to the utilization ratio of wind energy and has improved.
Description
Technical field
This utility model relates to a kind of wind power equipment, particularly relates to the blade effectively dropping choke power generator.
Background technology
Wind-power electricity generation, as a kind of regenerative resource, is widely used；The windward side of the blade of existing wind-driven generator is mainly semicircular structure or ellipsoidal structure, and this structure comparison is firm, it is not easy to damage, but the air drag of existing blade is relatively big, and wind energy utilization is less, and loss of energy is also bigger.
Summary of the invention
Main purpose of the present utility model is in that for prior art Problems existing, and proposes a kind of blade effectively dropping choke power generator.
In order to achieve the above object, the technical solution of the utility model is as follows:
Blade involved by this utility model includes housing, the front end of described housing is semicircular structure, the afterbody spur type of described housing, described enclosure interior is hollow structure, it is provided with bracing frame in described hollow structure, described bracing frame is arranged on the widest part of hollow structure, and the front end of described housing is provided with triangle boss.
The limit of described triangle boss is tangent with the limit of semicircular structure.
Described housing is that metal alloy compacting forms.
Described housing is provided with enhancement Layer.
Described enhancement Layer is glass layer.
Described bracing frame is I shape.
The beneficial effects of the utility model are in that: this utility model is by arranging triangle boss structure in the windward side of blade so that the operationally suffered air drag of blade is less, and loss of energy is also corresponding less, and the utilization rate for wind energy is significantly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein: 1 is housing, 2 is enhancement Layer, and 3 is hollow structure, and 4 is bracing frame, and 5 is boss.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further:
As shown in Figure 1, blade involved by this utility model includes the housing 1 of metal alloy compacting, housing 1 is added with the enhancement Layer 2 that glass fiber material is made in pressing process, the front end of housing 1 is semicircular structure, the afterbody spur type of housing 1, housing 1 is internal is hollow structure 3, the bracing frame 4 of I shape it is provided with in hollow structure 3, bracing frame 4 is arranged on the widest part of hollow structure 3, the front end of housing 1 is provided with triangle boss 5, and the limit of triangle boss 5 is tangent with the limit of semicircular structure.
The present embodiment is by arranging triangle boss structure in the windward side of blade so that the operationally suffered air drag of blade is less, and loss of energy is also corresponding less, and the utilization rate for wind energy is significantly improved.
