Abstract
A novel carbon fiber blade of a wind-driven generator comprises a blade body and a blade root connected therewith, wherein the blade body is a hollow casing; the blade root is made of an intact metallic material; and the blade casing is formed by connecting a reinforcement skeleton with concrete poured on the reinforcement skeleton. In order to achieve solidness and durability of the blade, the material is made by adding carbon fiber composite materials. The blade skeleton comprises longitudinal reinforcement ribs and a honeycomb skeleton, which are connected; the blade root is connected with the longitudinal reinforcement ribs; the honeycomb skeleton is longitudinally distributed along the blade casing and is connected with the longitudinal reinforcement ribs; and besides, the blade root is connected with reinforcing rib plates, and the reinforcing rib plates are respectively connected with the reinforcement skeleton and the concrete poured on the reinforcement skeleton. The novel honeycomb skeleton enables the whole blade structure to be more firm, and the blade has the double functions of thermal conduction and thermal radiation.
Description
Technical field the utility model relates to a kind of novel electricity generator blade, particularly relates to a kind of carbon fiber blade structure for wind driven generator.
Background technique is along with the development of fan blade designing technique, and units such as generator constantly present the trend that gradually changes to choosing of blade.Blade is the parts of the most basic and most critical in the wind-driven generator, and its good design, quality and superior performance are the determinant factors that guarantees the normal stable operation of unit reliably.Yet, having had new direction for choosing of material, chord length extrusion modling blades such as wooden blade in the past and cloth covering blade, girder steel glass fiber cloth covering blade, aluminum alloy are about to become the object that people ignore.For wind-driven generator, carbon fiber is upcoming trend.The big inexpensive E-glass reinforced plastic of general more small-sized blade (long) amount of selecting for use as 22m, resin matrix is based on unsaturated polyester, also can select vinyl acetate or epoxy resin for use, and relatively large blade adopts the hybrid composite of CFRP or CF and GF (as more than the 42m), and resin matrix is based on epoxy.Begun to adopt carbon fiber composite (CFRP) at present, the blade maximization has been complied with in the exploitation of blade material and light-weighted direction develops.Existing wooden blade, its defective is difficult for making meander configuration exactly, also is not suitable for large and medium-sized generator.Chord length extrusion modling blades such as aluminum alloy, though in light weight, be easy to processing, can not accomplish blade from blade root to the blade tip convergent.
The summary of the invention the purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of heating fast, high, firm, corrosion-resistant, the nonabradable novel wind generator blade of efficient.
To achieve these goals, the scheme that its technical problem that solves the utility model adopts is for making the novel carbon fiber blade of wind-driven generator, comprise blade body and the root of blade that is attached thereto, blade body is a hollow shell, the metallic material of blade root position integral body is made, and blade shell is connected and composed by Framework Of Steel Reinforcement and the concrete poured into a mould on Framework Of Steel Reinforcement.For making blade of the present invention reach firm and serviceability, material adopts and adds the carbon fiber composite making.
The blade skeleton is connected and composed by longitudinal steel bar and honeycomb type skeleton, and root of blade is connected with longitudinal steel bar; Its honeycomb type skeleton vertically distributes along blade shell, and is connected with described longitudinal steel bar.In addition, root of blade is connected with the reinforcement gusset, strengthens gusset and is connected with Framework Of Steel Reinforcement and the concrete poured into a mould on Framework Of Steel Reinforcement respectively.
The beneficial effects of the utility model are that the utility model is a carbon fiber structural, and relatively the blade of wind-driven generator of traditional glass steel structure has better intensity and serviceability, and is not easy to wear.Novel honeycomb structure skeleton makes the whole blade structure more firm, and has transmission of heat and the dual heat conduction function of thermal radiation.
Description of drawings
Fig. 1 looks schematic representation for master of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Embodiment
Fig. 1, reference character shown in Figure 2 are as follows: root of blade 1, honeycomb skeleton 2, vertically skeleton 3, strengthen gusset 4, concrete 5.
In the schematic representation of Fig. 1, Fig. 2, be primarily characterized in that: blade body and the root of blade 1 that is attached thereto, described blade body is a hollow shell, root of blade 1 answers steel to make, described blade shell is connected and composed by the concrete of pouring into a mould on carbon fiber skeleton and the carbon fiber skeleton 5, and the blade skeleton is connected and composed by honeycomb skeleton 2 and vertical skeleton 3.In addition, root of blade 1 is connected with strengthens gusset 4, strengthens gusset 4 and is connected with skeleton and the concrete 5 poured into a mould on skeleton respectively, so makes blade body and reinforcing bar root 1 that better join strength is arranged.
Working process of the present utility model is as follows: weld longitudinal steel bar on root of blade, and gusset 4 is strengthened in welding between root of blade and longitudinal steel bar.Make honey comb like skeleton then, vertical skeleton is connected with the iron wire ligation with the linking point of honeycomb, form the skeleton of blade, insert the core body that foamed material is made at the center of skeleton, the shape of core body and the shape of blade body match.Use cement material (or timber, alloy material) to make mould again, the top of mould has concrete sprue gate, and the inner chamber of mould is identical with the shape of blade, then the skeleton that has core body of blade is inserted in the inner chamber of mould, pour into concrete 5 from the sprue gate, vibration moulding, the dry demoulding.
