Description
Technical field
This utility model is related to wind-driven generator production technical field, and in particular to a kind of fan blade core material structure.
Background technology
Blade of wind-driven generator is shell structure made by a composite, point root, shell, Os Draconis three in structure
Part.Type is various, there is tip, tack, gib head, the tip with wing flap etc..Manufacturing process mainly include formpiston → turn over former →
Laying → be heating and curing → the demoulding → polishing surface → spray painting etc..Blade is a large-scale composite structure, its weight
More than 90% is made up of composite, and every electromotor typically has three blades, single blade composite wood of electromotor of 1.5MW
Material is up to 6 tons, and the fan blade individual cigarette weight of more than 3MW is more than 10 tons.As blade becomes increasing, the market competition adds
Play, blade manufacturers pass through their design of optimization to retain its competitive edge.
Blade design person and manufacturer by removing unnecessary material, and which material assessed can be in the different portions of blade
Position plays maximum work and uses to optimize cost and weight.For near the root of blade for needing high-strength core, cork wood is a kind of good
Good candidate material.But, when large-scale blade is produced, the transmutability of cork wood can limit design engineer and be optimized.Because
Cork wood is a kind of woodwork of spontaneous growth, between the different wood for producing cork wood core, its density, intensity and hardness to become
Change is very big, and this wood-based product can also absorb moisture causes change in size.Consider from the factor such as mechanical property and price,
Being currently used for wind power generation blade core can adopt foam mostly, in being filled in bearing carrier sandwich, but existing bubble
Foam core material structure is single, filling dead angle easily occurs, destroys the equilibrant of blade.
Utility model content
In view of above-mentioned background, this utility model provides a kind of fan blade core material structure, designs simple, it is easy to fill, anti-
Only there is filling dead angle.In order to solve above-mentioned technical proposal, this utility model is adopted the following technical scheme that：
A kind of fan blade core material structure, is arranged on inside blower fan tabletting, including core body, and the core body includes
Some separation blocks one, between two adjacent separation blocks one separation trough one is provided with, if the separation block one is provided with involvement
Hole is connected, the bottom of the core body is provided with connector.
A kind of fan blade core material structure that this utility model is provided, can be further arranged to the material of the core body
Matter adopts foam board.
A kind of fan blade core material structure that this utility model is provided, can be further arranged to the connector and be set to
It is netted, prevent core body from disconnecting, the carrying out of filling work is not utilized, while mitigating the weight of fan blade.
A kind of fan blade core material structure that this utility model is provided, can be further arranged to the separation block one includes
Some separation blocks two, are provided with separation trough two between two adjacent separation blocks two, progressive to increase the convenience for filling work,
Ensure to occur without filling dead angle in fan blade simultaneously.
A kind of fan blade core material structure that this utility model is provided, can be further arranged to be set on the separation block two
There is the connection through hole, resin is packed in connection through hole, strengthen the fastness of connection.
This utility model provide a kind of fan blade core material structure, can be further arranged to the separate slot two with it is described
The spacing for being smaller than the separation trough one and the connector of connector, it is to avoid separate block two and spread out, make the core
Material body integrally excessively disperses, and is unfavorable for filling the carrying out of work.
A kind of fan blade core material structure that this utility model is provided, can be further arranged to the bottom of the separation trough one
Portion is set to 2-5mm with the spacing of the connector.
In sum, core body is separated into different separation blocks one by this utility model, is easy to for core to be converted into difference
Shape, be conducive to fill work carrying out；Different spacing blocks two are further divided on the basis of block one is separated, it is progressive
Increase the convenience of filling work, while ensureing to occur without filling dead angle in fan blade；It is logical that connection is set on spacing block two
Hole, to potting resin in connection through hole when pouring, enhancing is fixedly connected effect；In addition, the material of core body adopts cystosepiment
Material, while its stability is ensured leaf quality is reduced, and makes blade increase wind catching area while rigidity is met.
Description of the drawings
Preferred implementation of the present utility model is carried out below in conjunction with the accompanying drawings describing in detail or preferably, wherein,
Fig. 1 is a kind of schematic diagram of fan blade core material structure of this utility model；
Wherein：1. core body 2. separates 5. connector of the connection through hole of one 3. separation trough of block 1 6. and separates block two
7. separation trough two.
Specific embodiment
Refer to the attached drawing 1 is described further to a kind of embodiment of fan blade core material structure of this utility model：
A kind of fan blade core material structure, is arranged on inside blower fan tabletting, including core body 1, and the core body 1 is wrapped
Some separation blocks 1 are included, between two adjacent separation blocks 1 separation trough 1 is provided with, be easy to be converted into core body 1
Different shapes, is conducive to filling the carrying out of work；The separation block 1 is provided with some connection through holes 4, to connection when pouring
Potting resin in through hole 4, enhancing is fixedly connected effect, and the bottom of the core body 1 is provided with connector 5.
The material of the core body 1 adopts foam board, and while its stability is ensured leaf quality is reduced, and makes leaf
Piece increases wind catching area while rigidity is met.
The connector 5 is set to netted, the weight of one side mitigation fan blade, on the other hand prevents core body from breaking
Open, do not utilize the carrying out of filling work.
The separation block 1 includes some separation blocks 26, and between two adjacent separation blocks 26 separation trough is provided with
27, the progressive convenience for increasing filling work, while ensureing to occur without filling dead angle in fan blade.
The separation block 26 is provided with the connection through hole 4, and resin is packed in connection through hole 4, strengthens the jail of connection
Solidity.
The spacing for being smaller than the separation trough 1 and the connector 5 of the separation trough 27 and the connector 5,
Avoid separation block 26 from spreading out, the entirety of the core body 1 is excessively disperseed, be unfavorable for filling the carrying out of work.
The bottom of the separation trough 1 is set to 2-5mm with the spacing of the connector 5.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art
