Description
Technical field
The utility model belongs to technical field of composite materials, and in particular to a kind of etch-proof wind electricity blade of leading edge.
Background technique
Wind electricity blade is generally by two half-shells: the face blade PS and the face blade SS by leading edge, rear, leading edge web and after
Edge web position is bonded with adhesive and is formed；The face blade PS and the face blade SS are made of fiber laminboard layer plywood and crossbeam, institute
The fiber laminboard layer plywood stated is fiber-reinforced resin matrix compound material.
The structure type has the following problems:
Leading edge corrosion: since blade inlet edge is made of fiber-reinforced resin matrix compound material, so blade inlet edge is vulnerable to ring
Border corrosion, such as: rainwater (acid rain) erosion, dust storm impingment corrosion, ultraviolet ageing, flying bird mosquito hit pollution corrosion etc.；Therefore,
Generally need to coat polyurethane as protective coating, to resist environmental corrosion in blade surface；However leaf longevity requires to be greater than
20 years, in the case, the protection of protective coating increased with runing time, and protective capacities gradually weakens, finally in above-mentioned ring
Under the continuous corrosion in border, so that blade inlet edge is destroyed, blade generated energy is gently then influenced, quality occurs for heavy then blade damage
Accident.With wind electricity blade the Enlargement Tendency, offshore wind farm further develops, and the use environment of large-scale blade is more complicated and tight
It is severe, while maintenance and repair is more difficult, up-front corrosion protection becomes one of the technological difficulties that large-scale blade need to capture.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of etch-proof wind electricity blades of leading edge, solve current wind
The corrosion protection problem of electric blade inlet edge.
Used technical solution is the utility model to solve above-mentioned technical problem: a kind of etch-proof wind-powered electricity generation leaf of leading edge
Piece is bonded by the shelly-shaped face blade SS in the half shelly-shaped face blade PS and half is opposite, and the face blade PS and the face blade SS are by fibre
Dimension sandwich laminate is made, and the face blade PS and the face blade SS include blade inlet edge and trailing edge, the blade in the face blade PS
The blade inlet edge in leading edge and the face blade SS is laid with fibre metal alloy laminate, and fibre metal alloy laminate is by least one layer
Fiber and one layer of metal material are constituted, and every layer of fiber sandwich of the thickness of every layer of fibre metal alloy laminate and wind electricity blade
The thickness of laminate is identical.
When fibre metal alloy laminate described in the utility model is made of multi-layer fiber and multiple layer metal material, metal material
Fibrous layer is pressed from both sides between the bed of material and metal material layer.
The thickness of the metal material layer of fibre metal alloy laminate described in the utility model is equal with fiber layer thickness.
Trailing edge described in the utility model is equipped with fibre metal alloy laminate, and it is laminated to be laid with fibre metal alloy
The thickness of plate is generally 0.5-5mm, is made of two or more layers fiber and metal alloy.
It is closed the beneficial effects of the utility model are: the utility model devises fibre metal in the front edge area of corrosion-vulnerable
Golden laminate structures improve blade inlet edge and resist impact and resist the ability of rain erosion, make blade inlet edge corrosion protection ability
It is promoted；After the protective coating of blade falls off, remain to improve blade by the erosion damages of natural environment,
Leaf longevity reduces the maintenance costs such as replacement coating.
