Description
Technical field
It the utility model is related to a kind of fastener for wind-power electricity generation, it is specifically a kind of for wind-driven generator
Blade bolt component.
Background technology
At present, the blade installation of wind-driven generator is more using nuts and bolt cooperation is intersected, and will intersect nut and is installed to
In radially installed hole, axial connecting screw is installed in axially mounted hole and with intersecting nut fastening, connecting screw is connected
The connection installation of wind electricity blade is completed on to the complete machine wheel hub of wind-powered electricity generation leaf.There is following deficiency for the above prior art：1st, pass
The bolt assembly unreasonable structure of system, influences the fixing intensity of blade；2nd, traditional bolt is exposed outside, receives wind throughout the year and blows rain
Leaching, it is easy to the security of the whole wind-driven generator of corrosion impact；3rd, since blade constantly moves, bolt is easy to pine,
Equally it is unfavorable for the stability of blade；4. traditional wind-driven generator bolt assembly installation is relatively difficult.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of blade bolt component for wind-driven generator, on solving
State existing technical problem.
Specifically scheme is：A kind of blade bolt component for wind-driven generator, the blade bolt component include double end
Bolt, stud middle part are screw rod, and the both ends of screw rod are respectively arranged with the excessive conical surface, and the conical surface of crossing connects respectively
There is long threaded rod and short thread bar, the short thread bar is threaded with intersection nut, and the long threaded rod end point is set
It is equipped with interior hexagonal.The design of the excessive conical surface is so that the internal diameter of screw portion is improved relative to long threaded rod and short thread bar smaller
Operating space between blade bolt component, improves installation effectiveness；, can meanwhile cone structure has stronger intensity
Ensure the stability of blade.The design of interior hexagonal also functions to the effect for facilitating demounting bolt component, due to bolt assembly for a long time
Stress friction, inevitably occurs long threaded rod termination deformation, and very hard, interior hexagonal is replaced in deformed bolt assembly dismounting
It is not easy affected by environment and deforms inside bolt.
Further, the blade of wind-driven generator is after installation is complete, the screw portion of bolt assembly be typically exposed to it is outer, often
Year receive wind and scrape and drench with rain, it is easy to which the security of the whole wind-driven generator of corrosion impact, so in order to improve device security, subtracts
The degree that small screw is corroded, screw rod periphery are socketed with protective case.
Further, the protective case generally cylindrical shape, is formed, described two half by two semicircle cover body docking
The side joint of circular cover body is hinged, and the opposite side joint of described two semicircle cover bodies is provided with the connection of mutual cooperation
Ear, by bolt arrangement or snaps connection between the engaging lug.The design of above-mentioned protective case passes through two semicircle cover bodies, profit
With articulated connection, fixed by the bolt arrangement between engaging lug, simple in structure, convenient dismounting, is easily replaced.
Further, the intersection nut is cylinder, and thread groove is provided with the middle part of the side for intersecting nut.
Further, the short thread bar end point is provided with anti-skid teeth line, and the anti-skid teeth line is counterclockwise
Turbine shape.It is along anti-skid teeth line direction, when short thread rod end head touches when short thread bar is screwed into thread groove
During thread-groove bottom, continue to rotate, under the action of anti-skid teeth line, short thread rod end head is gradually locked with thread-groove bottom, lock
It is next to be not easy to unclamp, short thread bar is substantially increased with intersecting the fixation between nut, and when blade rotates, short thread bar is with intersecting
It is not easily to fall off between nut.
Further, the outer end of the long threaded rod and short thread bar is respectively equipped with lead angle, the effect of lead angle be facilitate it is short
Threaded rod is inserted into thread groove, and long threaded rod is inserted into blade connecting hole, improves installation effectiveness.
The beneficial effects of the utility model：The blade bolt modular construction is reasonable, has higher fixing intensity, while conveniently
Dismount not easily to fall off；The design of protective case can be exposed outside to avoid screw rod, can effectively protect screw rod, prevents that it is excessively rotten
Erosion.
