With the development of wind power generating set technology and in short supply, the scale of wind power generating set single-machine capacity of land resource
Also it is increasing, from 1.5MW to 2MW 5MW is even developed into 3MW again.Due to the increase of wind-driven generator pool-size, its blade
Length also accordingly increases, if 1.5MW wind generator set blades length is usually in 37.5m or so, 2MW wind generator set blades
Length usually will exceed 50m in 42m or so, 3MW and above wind generator set blade length, this gives vane manufacturing and conveyer belt
Great difficulty is carried out.
Utility model content:
It is readily transported and installs the purpose of this utility model is to provide one kind, and the segmented wind-power electricity generation of stable connection
Unit wind wheel blade.
The purpose of this utility model is implemented by following technical solution, and segmented fan blade of wind generating set, it includes
The blade sections of at least two sections fiberglass, the blade sections are hollow structure, and one end of the blade sections is integrally formed with can punching press
Metal socket joint section, the metal socket joint section are designed manufacture by socket joint requirement, and the shape and size of the metal socket joint section are equal
Mutually interactive cooperation, the metal socket joint section can limit the axial direction between the adjacent blade sections with the cavity of the adjacent blade sections
Rotate;
Some inserting grooves are equipped with along socket joint direction in the metal socket joint section, in the cavity inner wall of the adjacent blade sections
Grafting block corresponding with the inserting groove is equipped with, the grafting block is mutually clamped with the inserting groove;
Screw hole is correspondingly provided with the metal socket joint section and therewith in the blade sections of socket joint,
Two pieces of adjacent blade sections are also connected by the hinged bolts in the screw hole;During manufacture, by two
After the mutual socket joint of block blade sections, once drill, it is ensured that its installation accuracy.
Further, the hinged bolts are dormant bolt, can fix the blade sections limit its mutual displacement and
The aerodynamic configuration of the blade sections is not interfered with without protrusion.
Further, the metal socket joint section is the light aluminium alloy socket joint section of intensity height, material.
Further, the grafting block is the light aluminium alloy grafting block of intensity height, material.
When manufacturing the blade sections, two connecting pins of the adjacent blade sections are closed with aluminium alloy socket joint section and aluminium respectively
Golden grafting block is as keel.
The advantages of the utility model:The utility model can be manufactured without large-scale complex device, simple production process, together
When fabricated structure, be greatly saved cost of transportation, and adjacent blade segment by the way of socket joint+dormant bolt is fixed will point
Section blade is linked to be entirety, can be easy to the blade assembling of wind power generating set erecting bed, be adapted to Large-scale Wind Turbines
Exploitation.
