Description
Technical field
It the utility model is related to technical field of wind power generation, more particularly to wind electricity blade technical field.
Background technology
Wind electricity blade is the important component of wind power plant, it is generally the case that is needed the root of wind electricity blade and wheel
Hub connects.Wind turbine power generation power is improved in order to capture more wind energies, can typically increase wind electricity blade size, but the length of wind electricity blade
Degree is bigger, and the moment of flexure of its root is bigger, and just the bonding strength of the root to wind electricity blade and wheel hub has higher requirement for this.
Existing fan blade, using the method for bed course cloth, because bed course has certain weight in itself, irrigates in addition in root structure
Process can absorb resin；So not only consume raw material but also add the weight of blade, and bed course cloth and trailing edge
It is difficult to be brought into close contact, it is impossible to the irregular type face of matching trailing edge well, accordingly even when having used substantial amounts of bed course cloth still
Trailing edge gaps can not be so controlled in critical field.And after resin by injection, surrounding easily forms rich buildup of resin or filling
Cavity is noted, and the field strength and bonding force of rich buildup of resin or formation perfusion cavity are relatively low, due to blade in use
It can bear, compared with big load, now, to be likely to result in and blade cracking situation occur, so as to cause device damage or cause safe thing
Therefore.Therefore effectively control trailing edge is bonded gap, rich buildup of resin or perfusion cavity how is avoided, to improve product reliability
It is technical problem urgently to be resolved hurrily.
The content of the invention

The utility model provides a kind of wind electricity blade, and the wind electricity blade structure includes the high tabletting of blade, blade low voltage sheet, institute
The high tabletting of blade is stated, blade low voltage sheet includes crossbeam, core and glass fabric, it is characterised in that the high tabletting trailing edge
Inner chamber is provided with matched moulds frothing foam module.
Preferably, the matched moulds frothing foam module parcel cloth and lofted foam material.
Preferably, the frostproof froth n material is PVC.
Preferably, the lofted foam material is drilled with holes drilled through, and the holes drilled through is that vertical through holes or surface are opened
Groove, it can ensure that resin can be seeped into housing layer of cloth under hole in filling process, so be avoided due to frothing foam mistake
Thickness causes under frothing foam layer of cloth to irrigate incomplete problem, and one is formed in frothing foam after resin solidification in this exit orifice or groove
Each and every one column structure or network structure, frothing foam is connected with housing by these structures, so that trailing edge intensity obtains
To enhancing.
Preferably, the trailing edge surface of internal cavity is equipped with housing layer of cloth.
Preferably, the matched moulds frothing foam module is arranged on housing layer of cloth.
The manufacture method of the wind electricity blade, described wind electricity blade include high tabletting and low voltage sheet, it is characterised in that described
Method include the laying step of high tabletting trailing edge, the step includes：
A. matched moulds frothing foam module is prepared, trailing edge cavity shape is drawn by leaf model, removed by theoretical calculation
The thickness of housing laying, then the thickness of the bonded structural adhesive of setting is subtracted, theoretical shape needed for trailing edge bonding is obtained for preparing
Frothing foam；
B. housing laying is laid；
C. matched moulds frothing foam module is laid；
D. upper auxiliary material after laying terminates, perfusion solidification, solidification remove auxiliary material after terminating；
E. edge in front of the blade, trailing edge smearing structure glue；
F. high tabletting and low voltage sheet is made to be bonded together；
Preferably, lofted foam material is wrapped up with glass-fiber-fabric during practical application, parcel cloth is formed with lofted foam material
One complete matched moulds frothing foam module.
Preferably, because lofted foam material has certain thickness, and frothing foam is on housing layer of cloth
Guarantee housing layer of cloth can be irrigated effectively, and frothing foam is drilled with vertical through holes or surface fluting to ensure to irrigate
Journey resin can be seeped into housing layer of cloth under hole, so avoid to cause layer of cloth under frothing foam because frothing foam is blocked up
Incomplete problem is irrigated, forms column structure one by one or netted knot in this exit orifice or groove after resin solidification in frothing foam
Structure, frothing foam is connected with housing by these structures, so that trailing edge intensity is strengthened.
In summary, a kind of wind electricity blade provided by the utility model, can effectively solve the problem that because bed course cloth can not be good
Match the irregular type face of trailing edge and caused by trailing edge bonding gap it is excessive the problem of, by trailing edge gaps control marking
In quasi- scope, so as to eliminate after resin by injection, surrounding readily forms rich buildup of resin or perfusion cavity, effective to improve
Field strength and bonding force.
Simultaneously as being drilled with holes drilled through on frostproof froth n material or being provided with groove, so avoid due to frothing foam
It is blocked up to cause under frothing foam layer of cloth to irrigate incomplete problem, formed in this exit orifice or groove after resin solidification in frothing foam
Column structure or network structure one by one, frothing foam is connected with housing by these structures, so that trailing edge intensity
Strengthened.So that blade can be born compared with big load in use, cause device damage so as to reduce or cause safety
The probability of accident.
