Abstract
The utility model relates to a wind power generation equipment part, in particular to a wind driven generator blade. The wind driven generator blade comprises a shell and a web which is supported inside a shell cavity, the root of the shell is the root of the blade, and the top of the shell is the tip of the blade. The wind driven generator blade is characterized in that a high-performance resin matrix main beam is arranged inside the shell, two ends of the web abut against the high-performance resin matrix main beam, and the shell is an oxirene resin matrix shell or an unsaturated polyester resin matrix shell. According to the wind driven generator blade, the high-performance resin matrix is utilized for the main beam part, convenience of a main beam process is improved, and meanwhile, resin which is middle in strength, low in cost and free of heating solidification is utilized for other auxiliary force bearing components (a blade shell). Material cost can be reduced, leading-in time of the resin during a preparing process of the blade is obviously reduced, heating is not needed during a solidification process of the blade, and heating equipment cost and blade production time of a blade mould are reduced.
Description
Technical field
The utility model relates to a kind of wind power plant parts, specifically a kind of blade of wind-driven generator.
Background technique
Be accompanied by the full-fledged of the implementation of Renewable energy policy and wind-power electricity generation machine technology, the type size of wind power generating set is increasing, using scope is more and more extensive.
Blade is as the key components and parts of wind power generating set, and its weight and strength characteristics have important impact to the ride quality of wind power generating set.Along with the continuous increase of unit model, consider the generating efficiency of unit and the bearing strength characteristic of set tower frame and foundation structure, the maximization of blade and light-weight design research are the inexorable trends of blade of wind-driven generator technical development.
Research and development along with blades of large-scale wind driven generator, wind power generating set needs larger wind wheel wind sweeping area, to obtain more wind energy transformation as electric energy, this has just caused the increase of blade of wind-driven generator length and the load of blade to increase, the blade girder is as the main load-carrying member of blade of wind-driven generator, its width and laying thickness all will increase accordingly, and to guarantee the safe and reliable of structure, blade structure of the prior art and material can not satisfy the requirement of large blade.
In the blade of domestic wind field operation, quite the blade of vast scale adopts epoxy-resin systems, and blade damages the position and mostly is leading edge, trailing edge, the surperficial covering of blade shell etc., if blade damages, uses epoxy resin and fibre cloth to repair, need to be heating and curing, but due to domestic wind field inclement condition, temperature is low, high humidity, be difficult to reach the desirable condition of cure of resin, the difficulty that causes blade to keep in repair is large, effect is not high.Thereby need to improve blade and use material, facilitate the operation and maintenance of blade.
Summary of the invention
The utility model provides a kind of blade of wind-driven generator for the problems referred to above, has solved prior art Leaf frangibility, intensity difference, yielding defective.
According to the technical solution of the utility model, described blade of wind-driven generator, comprise housing and web, described web is supported in shell cavity, the root of described housing is root of blade, and the top of housing is blade tip, it is characterized in that: the resin matrix girder is located in housing, the web two ends withstand on described resin matrix girder, and described housing is epoxy vingl ester resin base body housing or unsaturated polyester resin base body housing.
As further improvement of the utility model, described resin matrix girder is thermosetting epoxy resin matrix girder or thermosetting polyurethane resin matrix girder or thermoplastic polyether ether ketone resin matrix girder or thermoplastic poly diphenyl sulfide resin matrix girder.
As further improvement of the utility model, described housing comprises upper strata housing and lower floor's housing.
Technique effect of the present utility model is: in blade, most blade loadings have been born at the girder position, and the bearing capacity of girder is mainly determined by width and the thickness of girder section, under the prerequisite that guarantees the main beam structure rigidity property, adopt high performance resin system, as epoxy resin, polyurethane resin, can relatively reduce laying thickness, improve the convenience of girder technique; Simultaneously on all the other non-main load-carrying members (blade shell), adopt that intensity is medium, cost is lower, do not need the resin that is heating and curing, as unsaturated polyester resin, epoxy vingl ester resin etc., not only can reduce cost of material, obviously reduce the importing time of resin in the blade preparation process simultaneously, and do not need in the blade solidification process to heat, reduced blade mold heating plant cost and blade production time; The utility model blade of wind-driven generator in maintenance process, is selected coupling housing reisn base material used, after fibre cloth is infiltrated resin in addition, directly hand is stuck with paste the surface of damaging at blade shell, do not need to be heating and curing, reduced maintenance cost, improved agility; In sum, the utility model is on the basis of the strength character that guarantees blade, and blade girder and housing adopt the resin matrix of two kinds of general layout characteristics, can reduce the cost of material of blade, and the production of blade and also raising greatly of maintenance efficiency.In addition, if girder adopts the thermoplastic resin matrix, after blade reaches the time limit in working life, can carry out recycling to girder part material, avoid the pollution to environment.
