Abstract
The utility model discloses blades of a large-scale wind generating set of a split structure. Structurally, the blades as a whole are divided into a blade body and rear-edge split bodies which are assembled and connected in bolted connection. The blades of the large-scale wind generating set are characterized by having optimized split structure design, excellent aerodynamic performance, convenient manufacturing and process arrangement, reducing overall mould cost due to the utilization of a large mould with relatively smaller width change and a small mould, reducing manufacturing defect probability when the split bodies is molded one by one, and reducing transportation cost due to one-by-one transportation and on-site mounting.
Description
Technical field
The utility model belongs to the structural design of Large-scale Wind Turbines blade to be improved, and is specifically related to the Large-scale Wind Turbines blade of a kind of minute body structure.
Background technique
In the structural design of Large-scale Wind Turbines blade, be typically designed to by upper and lower casing and the bonding structure that forms of crossbeam, according to the rule of blade profile design, be to increase afterwards earlier to reduce along length of blade direction blade chord length.There is following problem in such project organization: 1) desirable vane aerodynamic profile as shown in Figure 1, the blade root place carries out the transition to maximum chord length very soon, the change in shape near blade profile maximum chord length and cross section, front and back is more violent, shape transition has some setbacks or not deployable situation near the maximum chord length, form manufacturing deficiency easily, therefore in practical design, blade root and maximum chord length transition are not very violent, the size of maximum chord length is also corresponding to be reduced, and such blade profile is to sacrifice aerodynamic quality to solve technological problems.2) even the maximum chord length size has reduced, the blade mold size is still very big, the manufacture cost height.3) blade transportation difficulty, the utilization ratio of transport vehicle is low, the cost of transportation height.
Summary of the invention
Technical problem to be solved in the utility model is: the Large-scale Wind Turbines blade that a kind of minute body structure is provided.
The technical solution of the utility model is:
The Large-scale Wind Turbines blade of a kind of minute body structure is characterized in that: integral blade is divided into blade body and trailing edge split part two-part from structure, and assembling is connected blade body with trailing edge split part.
Blade body is that bolt is connected with trailing edge split part assembling mode.
The utility model effect is:
Characteristics are: the split-type structural design of optimization, good aerodynamic quality, the convenient manufacturing and processing arrangement, can use a width dimensions to change less big mould and a little mould relatively, overall die cost reduces, reduced the generation probability of manufacturing deficiency during the bulk-breaking moulding, bulk-breaking transportation, the on-the-spot installation have been reduced cost of transportation.

Embodiment
The Large-scale Wind Turbines blade of a kind of minute body structure shown in Fig. 3,4, integral blade is divided into blade body 1 and trailing edge split part 2 two-part from structure, and assembling is connected blade body with trailing edge split part.
Blade body is that bolt is connected with trailing edge split part assembling mode.
The utility model belongs to the structural design of Large-scale Wind Turbines blade to be improved, and is specifically related to a kind of realization of branch body structure of Large-scale Wind Turbines blade.The utility model is applied in the structural design of Large-scale Wind Turbines blade, realizes simplifying the manufacturing and the processing arrangement of blade by the design mix body structure, has reduced the generation probability of manufacturing deficiency, makes things convenient for the blade transportation and saves cost.
The utility model is the structure design characteristic at the Large-scale Wind Turbines blade, by desirable blade aerodynamic configuration design blade, when blade is made with maximum chord length near vane trailing edge part and blade body make the branch body structure, install again or assemble after blade is transported to the wind field scene.
The utility model is achieved by the following technical programs.With reference to accompanying drawing 3,4, blade is divided into blade body and trailing edge split part two-part from structure.Two-part were made respectively when making, and were assembled into a blade after being transported to the scene, and assembling mode is that bolt connects.
The utility model is applied in the structural design of Large-scale Wind Turbines blade, realize improving the aerodynamic efficiency of blade by the design mix body structure, simplify the manufacturing and the processing arrangement of blade, reduced the generation probability of manufacturing deficiency, make things convenient for the blade transportation and save cost.
Present embodiment is the blade to the 1.5MW wind power generating set, and the final molding with blade in structural design is designed to blade body and trailing edge split part two-part.Blade sections rear edge part split at distance blade root 1-20m is made, and bind mode is that bolt connects, and the assembling of blade is finished in the sub-unit transportation at the wind field scene.
