Abstract
The utility model provides a protection device of aerogenerator root of blade bolt, includes that the cladding at the regional silica gel boundary belt of root of blade bolt, is equipped with the recess that aligns with root nut equipotential on the internal surface of silica gel boundary belt, the surface of silica gel boundary belt be equipped with extend in the biax of silica gel boundary belt to fibre cloth layer, the biax is to being equipped with the type of repairing putty layer outside the fibre cloth layer. The utility model discloses an if the silica gel boundary belt, it is tight to carry out whole in the bolt region of root of blade, has better protection fixed action, the internal surface of silica gel boundary belt establish with bolt top nut complex recess, avoid causing the unevenness phenomenon of silica gel boundary belt surface, can also avoid the silica gel boundary belt to produce the dislocation on the bolt for the root of blade appearance is more pleasing to the eye, if the biax is stuck with paste and is leveled bubble -free to fibre cloth layer, hand, make things convenient for the type of repairing of putty to handle for the surface is bright and clean, level and smooth.
Description
Technical field
The utility model relates to a kind of blade of wind-driven generator, particularly a kind of protective gear of wind power generator blade root bolt.
Background technique
In existing technique, because root of blade loses circle, after root of blade installs nut, there is larger uneven phenomenon.For making root of blade appearance looks elegant, need to use die-closing adhesive, repair type putty and repair type, transition processing to root of blade, its process is loaded down with trivial details, and the Master Cost of generation is also higher, bonding poor stability.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of protective gear stablized, operate easy wind power generator blade root bolt reasonable in design, functional, bonding.
Technical problem to be solved in the utility model is realized by following technological scheme; the utility model is a kind of protective gear of wind power generator blade root bolt; be characterized in; comprise the silica gel protected band being coated on root of blade bolt region; the internal surface of silica gel protected band is provided with the groove alignd with root nut equipotential; the outer surface of silica gel protected band is provided with biaxially scrim cloth; biaxially scrim cloth outside silica gel protected band is overlapped on root of blade bolt region, is biaxially provided with outside scrim cloth and repaiies type putty layer.
Technical problem to be solved in the utility model can also be realized further by following technological scheme, and silica gel protected band is connected with root of blade bolt region by adhesive layer.
Technical problem to be solved in the utility model can also be realized further by following technological scheme, and the fabric width of described biaxially scrim cloth is 250-300mm.
Technical problem to be solved in the utility model can also be realized further by following technological scheme, and the overlap joint of the bolt region outside described biaxially scrim cloth and silica gel protected band is of a size of 280-320mm.
The utility model is by establishing silica gel protected band, type process is repaiied to root of fan blade nut region, avoid the uneven phenomenon causing silica gel protected band outer surface, the internal surface of silica gel protected band establishes the groove coordinated with bolt upper cap nut, carry out entirety in the bolt region of root of blade tight, have and protect fixation preferably, silica gel protected band can also be avoided on bolt to produce dislocation, improve the stability of device, and make root of blade profile more attractive in appearance; If biaxially scrim cloth, hand sticks with paste smooth bubble-free, facilitates type of the repairing process of putty, makes any surface finish, smooth.Compared with prior art, it is reasonable in design, simple to operate, and beautiful shape effectively saves raw material, serves the effect of protection better.
Accompanying drawing explanation
