Abstract
A wind power generation leaf blade structure primarily consists of a body and a plurality of hollow leaf blades, which are divided into a plurality of segments, and the segments are connected with adaptation kits. Top face and bottom face of each of the leaf blades are provided with two troughs responding to each other, respectively. Each of the adaptation kits primarily comprises a plurality of gaskets and connecting pieces. When the structure is assembled, the gaskets stretch across the two adjacent leaf blades and correspond to the troughs; and the connecting pieces stretch across and are put on troughs of connected leaf blades, and then the connected leaf blades, gaskets and connecting pieces are tightly joined with bolts.

It is as follows to repeat the technical solution of the utility model again:
A kind of wind power generation blade structure of the utility model mainly is made up of body and several the blades that are hollow, each blade all blow with segmentation or other mode moulding made and can be divided into plurality of sections, therebetween and with a bonding apparatus as the coupler.
Wherein, the upper and lower wall of these blades respectively is provided with two corresponding mutually elongated slots; Bonding apparatus mainly has some liners and connecting sheet, and connecting sheet is provided with some circular holes; During assembling, with liner be across two be connected between blade in and corresponding with elongated slot, connecting sheet is then across on the elongated slot that places the blade that is connected, and the blade, liner and the connecting sheet that use bolt to be connected are closely linked and get final product.
Wherein, this liner can be assembled by the cylinder of some plastic colloids and is formed by connecting, and each cylinder all has and the corresponding groove of wearing of the circular hole of connecting sheet.
Wherein, this liner can be metal matter long plate shape, is provided with and the corresponding screw of connecting sheet circular hole.
Wherein, the blade that is connected wherein one have the less joint end of a bore.
A kind of wind power generation blade structure of the utility model, it has following all advantage and effect at least, and more progressive practical more than known person:
1. blade is made in the mode of mould air blowing or other sectional formings, and its processing procedure is easy and quick, so can reduce manufacture cost significantly.
2. liner is that full wafer connects, so that it wears groove (or screw) is easy accurately relative with the perforation of blade, can increase working efficiency.
3. but the utility model merogenesis is disassembled carrying, the restriction that is not subjected to the place or transports machinery.
4. when disassembling this creation, blade can be pulled down keeping with artificial simple and easy segmentation, and needn't employ slingcart, so more known person is easy easily.
