Abstract
The utility model relates to a wind turbine blade of a wind driven generator, and aims to provide a wind turbine blade with fine quality, high strength, convenient manufacturing and low production cost. The technical scheme includes that a blade main body of the die pressing glued type wind turbine blade is formed by splicing and fixing an upper blade and a lower blade, the die pressing glued type wind turbine blade is characterized in that a closed cavity is arranged inside the blade main body, the cavity is formed by connecting a groove of the upper blade with a groove of the lower blade, and the grooves are provided with a plurality of reinforcing ribs favorable for increasing strength and rigidity. The reinforcing ribs extend along a length direction of the blade. The upper blade and the lower blade are in adhesive connection by utilizing structural adhesive.
Description
Technical field
The utility model relates to a kind of wind-driven generator parts, specifically is the wind wheel blade of wind-driven generator.
Background technique
Along with the rise of global new energy trend, wind-power electricity generation has obtained unprecedented attention and popularization as a kind of pollution-free green energy.Wind wheel blade is the critical component of wind-power generating system, directly affects the performance ratio of whole system, and need have weatherability and the ageing resistance of using under the condition of long-term bad naturally out of doors border.In order to guarantee generator operation steadily and tower seat safety, not only require mass distribution that the light weight of blade also requires blade evenly, the precise control of boundary dimension precision, usability is reliable for a long time.
Traditional composite material wind wheel blade adopts hand to stick with paste the technology manufacturing more.The characteristics that hand is stuck with paste technology are manual operations, die sinking moulding, manufacturing efficiency is low and the resin solidification degree is often on the low side, only is suitable for the production that product lot quantity is little, the quality uniformity requirement is low.The shortcoming of hand paste explained hereafter wind wheel blade is apparent in view, and quality of product is bigger to workman's skilled operation degree and bad border condition dependence, and manufacturing efficiency is low and product quality reliability is poor, and the dynamic and static balance of product guarantees that property is poor, and reject rate is higher.For the demanding wind wheel blade of weight, generally adopt sandwich structure, this type of way is for the sandwich material with light-high-strength is filled in the wind wheel blade, plays the effect that reduces weight.The blade that hand is stuck with paste the technology manufacturing often since in the manufacturing process inhomogeneous, the fiber/resin of gel content to invade profit bad and solidify not exclusively, problems such as crackle, fracture and deformable blade appear in the using process easily, influenced the working life of wind wheel blade.
The model utility content
The purpose of this utility model provides a kind of improvement of wind wheel blade, and this wind wheel blade should be able to overcome disadvantages of background technology, has the advantages that quality is good, intensity is high, making is convenient, cost of production is low.
The technological scheme that the utility model proposes is: moulded glued formula wind wheel blade, its blade body fixedly forms with following sheet splicing by last slice, it is characterized in that being shaped in the described blade body airtight cavity, this cavity is formed by connecting by the groove of last slice groove and following sheet; Described groove position is shaped on some and is beneficial to the stiffening rib that improves strength and stiffness.
Described stiffening rib stretches along the length direction of blade.
Described last slice and following sheet between adopt structure glue bonding.
The wind wheel blade that the utility model provides makes leaf weight significantly alleviate owing to adopted cavity structure; At the reinforcing rib structure that last position and following sheet position make respectively, can make wind wheel blade keep suitable strength and stiffness, satisfied the requirement of wind-power generating system; In addition,, just can utilize die press technology for forming to obtain the blade of accurate surface configuration, make leaf quality significantly improve, and then obviously improve the efficient of wind-power electricity generation because blade is divided into last slice and the making separately respectively of following sheet; Also improve manufacturing efficiency, reduced cost of production.

Embodiment
Moulded glued formula wind wheel blade, its blade body by last slice 1 and 2 splicings of following sheet fixedly form, it is characterized in that being shaped in the described blade body airtight cavity 3, this cavity is formed by connecting by the groove 2-3 of last slice groove 1-3 and following sheet; Described tongue and groove position is shaped on some and is beneficial to the stiffening rib that improves strength and stiffness (visible last slice 1 groove position is shaped on stiffening rib 1-1 among the figure; The groove position of following sheet 2 also is shaped on stiffening rib 2-1); These stiffening ribs stretch (also can set the direction of extension of stiffening rib as required separately) along the length direction of blade.
Described last slice and the junction plane of following sheet between adopt structure glue to be adhesively fixed; Directly outsourcing of structure glue.In addition, the edge of blade also can be designed to mosaic structure (last slice edge 1-2 also just in time is embedded in down within the interior edge 2-2 of sheet); All stamp structure glue at the position of blade edge and stiffening rib like this, two monolithics intensity glued together just is far longer than the intensity of two monolithic edge applying blades, and in use, increase the service life of the blade of fitting than the edge, and turnover rate is low.
Described composite material is made up of reinforcing materials such as thermoset substrate resin such as polyester resin, vinylite and epoxy resin and glass fibre, carbon fibers, is the conventional material of making wind wheel blade.
Claims (3)
1. moulded glued formula wind wheel blade, its blade body is fixedly formed by last slice (1) and following sheet (2) splicing, it is characterized in that being shaped in the described blade body airtight cavity (3), this cavity is formed by connecting by the groove (2-3) of last slice groove (1-3) and following sheet; Described last slice groove position is shaped on some and is beneficial to the stiffening rib (1-1) that improves strength and stiffness, and the groove position of following sheet is shaped on some and is beneficial to the stiffening rib (2-1) that improves strength and stiffness.
