Abstract
The utility model provides a wind wheel cover which is mounted on a bracket of a wind power generator unit, and comprises an integrally formed cover body. At least three impeller holes for blades of the wind power generator unit to pass through are formed in the cover body. The wind wheel cover provided by the utility model has the advantages of being simple and convenient in installation, high in installation efficiency, lower in manufacturing cost and longer in service life.
Description
Technical field
The utility model relates to technical field of wind power generating equipment, particularly a kind of wind wheeling cover.
Background technique
Wind energy is as a kind of renewable energy sources of cleaning, and reserves are huge, and in today that the energy shortage problem is on the rise, wind-power electricity generation receives the increasing attention in various countries.Windmill (wind power generating set) is as using the most general a kind of wind generating unit, mainly by support, be arranged at blade on the support, constitute with the generator of blade running shaft interlock and the wind wheeling cover etc. that is arranged on root of blade.Wherein, the main effect of wind wheeling cover is that guiding changes wind direction, blocks and protect the wheel hub of air vane and support joint, prevents that foreign matter from getting into wheel hub, the protection device security.Therefore, good wind wheeling cover structure can greatly be improved the generating efficiency and the Safety performance of windmill.
A kind of wind wheeling cover of the prior art is shown in Fig. 1-2; This wind wheeling cover is assembled by three panels 1 and a cover plate 2; Be fixedly connected with 32 packing rings through 16 bolts, 16 nuts between adjacent two said panels 1; And to be stained with rubber weather strip at junction point, guarantee the soundness of wind wheeling cover.
Not enough below the wind wheeling cover of said structure exists: the connection between the 1. adjacent said panel 1 need be used many scattered parts, and installation process is very loaded down with trivial details; Though 2. rubber weather strip can prevent that rainwater from getting into wheel hub inside; But rubber can wear out in the process of using for a long time gradually, corrosion, and sealing effect meeting variation must regularly be changed; Otherwise can influence the working life of wind wheeling cover, this has just increased maintenance cost to a certain extent.
Summary of the invention
The utility model technical problem to be solved is wind wheeling cover complex installation process in the existing technology, and maintenance cost is higher, and a kind of simple installation is provided, and installation efficiency is high, the wind wheeling cover that cost is lower and working life is long.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is following:
A kind of wind wheeling cover is installed on the support of wind power generating set, comprises integrated cover body, forms the vane hole that at least three blades that are suitable for said wind power generating set pass on the said cover body.
In the above-mentioned wind wheeling cover, said cover body forms pilot hole away from the end face of said support; Said wind wheeling cover also comprises and being installed on the said pilot hole and with the cover plate of said pilot hole sealing.
In the above-mentioned wind wheeling cover, the joint at said cover plate and said pilot hole edge is provided with seal ring.
In the above-mentioned wind wheeling cover, the edge of said vane hole is provided with flange.
In the above-mentioned wind wheeling cover, said cover body type of being cylindrical body.
In the above-mentioned wind wheeling cover, said vane hole circumferentially evenly distributes along said cover body.
In the above-mentioned wind wheeling cover, said vane hole is three.
In the above-mentioned wind wheeling cover, said cover body is by the glass fibre reinforced plastic integral moulding.
The technique scheme of the utility model is compared existing technology and is had the following advantages:
1. the wind wheeling cover of the utility model comprises integrated cover body, forms the vane hole that at least three blades that are suitable for wind power generating set pass on the cover body.Integrated cover body; No longer need all kinds of scattered parts and Stamping Steel Ribbon during installation; Installation efficiency is high, and can also make things convenient for and guarantee reliably the soundness and the sealing of wind wheeling cover, and the situation that rainwater gets into wheel hub internal damage electrical equipment can not take place; Not only reduce the manufacturing maintenance cost of wind wheeling cover, simplified the installation process of wind wheeling cover simultaneously.In addition, integrated cover body smooth surface has also promoted the overall appearance degree of wind wheeling cover.
2. the wind wheeling cover of the utility model, the edge of vane hole is provided with flange.Such design can increase the intensity of cover body, makes cover body in installing and using process, be difficult for rupturing; And flange can also play certain spacing fixation to blade, reduces the risk of leaf abscission in the wind power generating set running to a certain extent.
3. the wind wheeling cover of the utility model, vane hole circumferentially evenly distributes along cover body, has guaranteed the gravitational equilibrium between a plurality of blades, has optimized the efficient of wind-power electricity generation, has increased the working life of wind power generating set.
