Description
Technical field
The present invention relates to a kind of wind turbine blade root platform assembling structures.
Background technique
The root platform of wind electricity blade is fixed on root of blade, enters wheel for sundries such as die-closing adhesives in blocking vane cavity
Hub, complete machine, and operating platform is provided to blade, wheel hub maintenance, guarantee Employee Security.
Currently, there are two types of the connection types of root platform and blade root: rigid connection and elastic connection.The outer wall of root platform
It is directly be bonded with root of blade, then enhanced using hand paste glass-fiber-fabric, it is this to be connected as being rigidly connected.Such connection,
In blower operation process, the deformation of blade root can be directly delivered to blade root baffle, lead to the stress level of blade root baffle local location
It is excessively high, occur cracking failure under fatigue load effect, and then influence the safe operation of blower, even results in the hair of safety accident
It is raw.Meanwhile can all increase production cost with die-closing adhesive and sealing glue sticking and with glass-fiber-fabric hand paste, and product appearance is not good enough,
Influence the overall aesthetic of product.
There is also all using the scheme of elastic glue connection, the program can be by blade root and root between blade root baffle and blade root
Rigid connection between portion's platform becomes being flexibly connected (elastic connection), squeezes to reach and weaken blade root deformation blade root baffle
The effect of.However, the elastic gum dosage in the program is huge, the cost of blade root baffle is significantly increased.
Summary of the invention
Against the above technical problems, the present invention proposes a kind of wind turbine blade root platform assembling structure, the assembling structure
Including root platform (1), ring flange (2), manhole cover (3), bolt (4), root of blade (5) and sealing ring (6)；Wherein,
The root platform (1) is generally round, and outer edge is provided with several circular through holes, and circular through hole is equidistantly equal
Even distribution；Several counterbores are equipped on the inside of the ring flange (2), the counterbore is matched with the through-hole on the root platform (1)；
The root platform (1) is assemblied on ring flange (2) by bolt (4), and the root platform (1) is assemblied in ring flange (2)
Left or right side；The inlet manhole for the disengaging that can tolerate towards others is provided on the root platform (1), the manhole cover (3) passes through the spiral shell
Bolt (4) is assemblied on root platform (1)；The sealing ring (6) are equipped between the root platform (1) and the ring flange (2),
For preventing sundries from entering wheel hub by gap, while blade root deformation can be buffered to the stress of the root platform (1)；It is described
Several through-holes are equipped on the outside of ring flange (2), via count is corresponding with the bolt number；The bolt will be described by the through-hole
Ring flange (2) is directly fixed on the end face of the root of blade (5).
Preferably, the manhole cover is circle.
Preferably, the manhole cover is rectangle.
Preferably, the manhole cover is polygon.
Preferably, the root platform is slab construction.
Detailed description of the invention
Fig. 1 is blade ring flange and the front view after the assembly of root platform in the present invention.
Fig. 2 is the cross-sectional view of blade ring flange and the assembly of root platform in the present invention.
Specific embodiment
Technical solution of the present invention is described further below with reference to Fig. 1-2 and specific embodiment.
In the description of the present invention, the orientation of instructions such as term " on ", "lower", "front", "rear", " top ", " bottom " or
Positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and simplification of the description, without
It is that the device of indication or suggestion meaning or part must have a particular orientation, be constructed and operated in a specific orientation, therefore not
It can be interpreted as limitation of the present invention.
Fig. 1 and Fig. 2 is blade ring flange and the front view and cross-sectional view after the assembly of root platform in the present invention.As schemed
Show, the present invention includes root platform 1, ring flange 2, manhole cover 3, bolt 4, root of blade 5 and sealing ring 6.Root platform 1 is whole
For circle, outer edge is provided with several circular through holes, and circular through hole is equidistantly uniformly distributed.It is equipped on the inside of ring flange 2 several
Counterbore, these counterbores are matched with the through-hole on root platform 1.Root platform 1 is assemblied on ring flange 2 by bolt 4.This reality
It applies in example, root platform 1 is assemblied in the left side of ring flange 2, but is not limited only to left side.The disengaging that can tolerate towards others is provided on root platform 1
Inlet manhole, manhole cover 3 is assemblied on root platform 1 by bolt.Sealing ring is equipped between root platform 1 and ring flange 2
6, for preventing in blade cavity the sundries such as die-closing adhesive to enter wheel hub by gap, while it is flat to root to buffer blade root deformation
The stress of platform 1.Several through-holes are equipped on the outside of ring flange 2, via count depends on root of blade bolt number.Root of blade bolt is logical
These through-holes are crossed, ring flange 2 are directly fixed on the end face of root of blade 5.Root platform 1, ring flange 2 and manhole when installation
The erection sequence of lid 3 can be determined according to the condition of production and operating habit etc..In the present embodiment, root platform 1 is slab construction, but
It is not limited to slab construction, manhole cover is circle, but is not limited only to circle, such as rectangle, polygon etc..
The assembling structure can achieve following effect:
(1) root platform is fit directly on blade flange disk in the present invention, and the deformation of blade root is first passed on ring flange again
It is transmitted to blade root baffle, weakens extruding of the blade root deformation to root platform, reduces root platform cracking failure frequency.
(2) root platform of the invention is not necessarily to secondary splicing, improves peace without being divided into several piece to enter blade cavity
Efficiency and standardization level are filled, reduces production cost, and improve the intensity and bearing capacity of root platform.
(3) present invention replaces bonding agent and sealant using elastic seal ring, without carrying out hand paste operation to root platform,
Production cost is reduced, and appearance is neat and artistic, is easier to meet customer need.
(4) this invention simplifies the installation of root platform, disassembly technique, so that the installation of root platform, disassembly and more
Changing jobs becomes simple, easily operated.
In the various embodiments described above, structure, setting position and its connection of each component be may be changed, at this
On the basis of inventive technique scheme, to improvement and equivalents that individual part carries out, it should not exclude in protection model of the invention
Except enclosing.
The above is only the preferred embodiment for the present invention.It should be pointed out that the member of ordinary skill for the art comes
It says, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications are also answered
This is considered as protection scope of the present invention.
