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.

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 utility model.
Fig. 2 is the cross-sectional view of blade ring flange and the assembly of root platform in the utility model.
Specific embodiment
The technical solution of the utility model is described further below with reference to Fig. 1-2 and specific embodiment.
The side of the instructions such as term " on ", "lower", "front", "rear", " top ", " bottom " in the description of the present invention,
Position or positional relationship are to be based on the orientation or positional relationship shown in the drawings, and are merely for convenience of description the utility model and simplification is retouched
It states, rather than the device or part of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation,
Therefore it should not be understood as limiting 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 utility model.Such as figure
Shown, the utility model includes root platform 1, ring flange 2, manhole cover 3, bolt 4, root of blade 5 and sealing ring 6.Root is flat
Platform 1 is generally round, and outer edge is provided with several circular through holes, and circular through hole is equidistantly uniformly distributed.It is set on the inside of ring flange 2
There are several counterbores, these counterbores are matched with the through-hole on root platform 1.Root platform 1 is assemblied in ring flange 2 by bolt 4
On.In the present embodiment, root platform 1 is assemblied in the left side of ring flange 2, but is not limited only to left side.Being provided on root platform 1 can hold
The inlet manhole of people's disengaging, manhole cover 3 are assemblied on root platform 1 by bolt.It is equipped between root platform 1 and ring flange 2
Sealing ring 6 for preventing in blade cavity the sundries such as die-closing adhesive to enter wheel hub by gap, while can buffer blade root deformation pair
The stress of root 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
Ring flange 2 is directly fixed on the end face of root of blade 5 by bolt by these through-holes.Root platform 1, ring flange 2 when installation
