Abstract

The utility model discloses an X-shaped wind turbine blade. A structure that the action of an external force is supported by self structural strength in a traditional vertical-axis blade is changed, and the action of the external force is supported with an X-shaped support tower of a wind turbine, thus greatly improving the capacity of resisting the action of the external force of the blade. The X-shaped wind turbine blade is composed of five parts, namely, a connection structure, a shape-fixing structure, a filling material, a framework structure and a surface structure, wherein the connection structure is used for the connection and the relative rotation of the blade and the tower; the shape-fixing structure is used for keeping the shape of the blade when the blade is stressed; the framework structure is used for bearing the action of the external force; the surface structure and the shape-fixing structure form a linear shape of the blade; the five parts are combined to form the X-shaped wind turbine blade.

Description

X-type pneumatic equipment blades made

Technical field

X-type pneumatic equipment blades made belongs to wind-driven generator and manufactures field.

Background technique

Be subject to the promotion of international Wind Power Generation trend, the manufacture of Chinese feature machine has entered the device fabrication ranks of large fan, the vertical axis wind-mill generator of particularly abroad abandoning, domesticly with wind, send out, state can make a lot of progress for the vertical axis aerogenerator MANUFACTURER of representative in vertical shaft fan manufacture, but the power factor of well-known vertical axis aerogenerator will be lower than horizontal axis wind-driven generator, the unique solution that improves generator single-machine capacity is the cut-off wind area that increases wind mill wind wheel, to overcome the factor of safety that the vibration that brings thus and stall form simultaneously, the wind wheel of X-type wind energy conversion system provides a kind of solution.

The character of existing vertical axis aerogenerator determines that the blade of existing generator is the structure of the structural strength support External Force Acting that relies on self, a little less than having determined that its lateral structure strength ratio, easily produces security incident when stall.

Summary of the invention

The utility model discloses a kind of X-type pneumatic equipment blades made that tolerance is strong, lightweight, cost is low under frequent wind-engaging power effect.

X-type pneumatic equipment blades made, changes the structure that structural strength that traditional vertical shaft blade relies on self supports External Force Acting, but supports External Force Acting with together with the X-type support tower of wind energy conversion system, has improved greatly the ability of the external force resistance effect of blade, it is by linkage structure, skeletal structure, Gu type structure, packing material, surface structure five parts form, it is characterized in that linkage structure and skeletal structure interconnect by solid type structure, mantle surface structure, insert packing material, form X-type pneumatic equipment blades made, blade connection structure is connected with X-type wind energy conversion system support tower and jointly supports together External Force Acting, linkage structure is used for the connection of blade and pylon and relatively rotates, Gu type structure keeps the shape of blade while being used for vane stress, skeletal structure is born External Force Acting, surface structure forms the streamlined contour of blade together with solid type structure, five parts are combined to form X-type pneumatic equipment blades made.

Linkage structure, for the connection of blade and pylon, comprises and is fixedly connected with and is flexibly connected two kinds.

Skeletal structure is divided two kinds of inner framework structure and outer skeletal structures, and inner framework structure is that flexible material or rigid material form inner framework structure by solid type structure tension or welding, and mantle surface structure, inserts packing material and form streamline vane; Outer skeletal structure is that surface structure and skeletal structure are made one, inside fills out packing material, by solid type structure, keeps blade streamlined contour.

Gu type structure shape is consistent with blade profile, by rigid material, to be made, each blade has two solid type structures at least.By the appropriate design of skeletal structure and solid type structure, can all or part of removal packing material.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.

The wind turbine blade structure of X-type shown in Fig. 1 sketch, solid type structure 2 and the linkage structure 1 at figure Leaf two ends interconnect, linkage structure 1 is for the connection with support tower, the shape of linkage structure is varied, mainly divide fixed and movable two kinds, flexible connection is conducive to angle and the aerodynamic brake of adjusting vane, linear frame structure material 3 is connected with solid type structure 2, linear frame structure material 3 comprises flexible material and rigid material two classes, streamlined contour when Gu type structure 2 is mainly used in keeping vane stress and the connection of skeletal structure, every blade is at least used two solid type structures on top, solid type structure in the middle of blade is different with the solid type structure shape at two ends but play equally the effect of maintenance blade external form.

Surface structure 4 is coated on the blade outer surface of inserting packing material 5, the effect of playing isolated environment corrosion and keeping the smooth smoothness of blade; According to the difference of model, and the appropriate design to blade skeletal structure and solid type structure, packing material can partly or entirely need not.

The pneumatic equipment blades made of X-type shown in Fig. 2 sectional view, what in figure, show is inner framework structure, and linear frame structure material 3 welding or tension are placed in blade interior, and packing material 5 forms blade profile shape, and mantle surface structure 4 forms blade; According to different requirements, can make outer skeletal structure blade, figure neutral line frame structure material 3 and surface structure 4 are made as to one and form outer skeletal structure blade; Two kinds of structure blades all need solid type structure to keep the external form of blade when stressed.

X-type wind turbine blade structure is simple, and after being connected with support tower, structural strength is very high, has very large Security under the extreme cases such as stall, and the more existing vane of vertical shaft wind-driven generator of manufacture cost decreases simultaneously.

Illustrate and be not used in restriction scope of the present utility model, multiple because its mode of execution has, technician can do various changes to the utility model, and these equivalent form of values are equal to the described scope of the application's claims.
