Description
Technical field
The utility model relates to a kind of wind power plant, refers in particular to a kind of blade of wind-driven generator bamboo composite material.
Background technique
At present, the blade that most in the world wind power plants use all adopts with glass fibre reinforced plastics and is the main structure body, but for the blade of length above 30 meters, the common carbon fiber that need add costliness just can remedy the deficiency on the material stiffness, this has increased the cost of manufacturing undoubtedly, manufacture cycle is long, and waste product that occurs in this leaf blade manufacture process and the damage product that use the back to damage all are not easy to reclaim, arbitrarily abandon and to cause environmental pollution, make reasonable these waste products of disposal and damage product need the bigger man power and material of cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bamboo composite material wind-driven generator blade cheap for manufacturing cost, with short production cycle, environmentally friendly is provided.
The technological scheme that provides according to the utility model, described blade body comprise sheet last slice with following sheet, root in blade body is provided with blade root, the top of blade body is a blade tip, the middle part of blade body is in the leaf, last slice be bonded one with following sheet by the matched moulds bonding strip, and between last and following sheet, form cavity, blade root and/or last slice and/or down sheet inside be filled with bamboo cord wood, the bottom edge in the blade outside of blade body is blade root pre-shaping parts.
Described bamboo cord wood, promptly tens of bamboo chips bond together by binding material, behind overcompaction, the strip object that cutting forms.
Blade root, last slice and following sheet inside all be filled with bamboo cord wood.Last slice with following sheet include outer frp layer and interior frp layer, be base material layer between outer frp layer and the interior frp layer, be filled with bamboo cord wood in the base material layer of in corresponding to leaf, locating, in leaf between the outer frp layer of the blade of both sides outside and blade inner edge and the interior frp layer and be base material layer between the bamboo cord wood.Last slice and following sheet and blade tip utilize the matched moulds bonding strip to be bonded into one.
Described body material, in glass fibre reinforced plastics, its function is that glass fibre is bonded together.Used body material is mixing of epoxy resin and curing agent in our technology, also can be called for short matrix resin.
Described matched moulds bonding strip, promptly when two half vane matched moulds up and down, at place, two blades bonding slit, card is used to strengthen the intensity of bonding part in the parts that certain width is arranged of inside.These parts are in advance according to the shape manufacturing of bonding part.
The utility model is cheap for manufacturing cost, and is with short production cycle, helps environmental protection.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is an A-A sectional view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: blade body comprise sheet last slice 2 with following sheet 3, root in blade body is provided with blade root 1, the top of blade body is a blade tip, the middle part of blade body is in the leaf, last slice 2 be bonded one by matched moulds bonding strip 10 and make it surround cavity 4 with following sheet 3, blade root 1 and/or last slice 2 and/or down sheet 3 inside be filled with bamboo cord wood 5, the bottom edge in the blade outside 12 of blade body is blade root pre-shaping parts 9.
Blade root 1, last slice 2 and following sheet 3 inside all be filled with bamboo cord wood 5, last slice 2 include outer frp layer 6 and interior frp layer 7 with following sheet 3, be base material layer 8 between outer frp layer 6 and the interior frp layer 7, be filled with bamboo cord wood 5 at the base material layer 8 that is arranged in leaf 11 positions, in leaf between the outer frp layer 6 of the blade of 11 both sides outside 12 and blade inner edge 13 and the interior frp layer 7 and be base material layer 8 between the bamboo cord wood 5, last slice 2 be bonded one by matched moulds bonding strip 10 with following sheet 3 and blade tip 14 parts thereof.
The big band of position of the curvature of blade root 1 is divided into many parts in advance and comes mfg. moulding die, utilizes mould to produce blade root pre-shaping parts 9, and these parts in the former of blade, are together inculcated as a whole with other laminated material lay then.Blade tip 14 parts also are bonded by matched moulds bonding strip 10.
The utility model can significantly reduce the use of glass cloth owing to use bamboo cord woods 5 in the base material layer 8 between outer frp layer 6 and the interior frp layer 7 in a large number, and its main advantage is:
At first, adopt China superior resources mao bamboon as raw material.In blades of large-scale wind driven generator,, except that main material glass fibre reinforced plastics, also to add carbon fibre cloth in order to satisfy requirement of strength.And carbon fibre cloth not only costs an arm and a leg, and the supply wretched insufficiency.Use the main structure body of mao bamboon as blade, rational Airfoil Design in addition can avoid using carbon fiber fully with interior blade for 40 meters long.
Secondly, reduce cost.Avoid using expensive carbon fibre cloth, therefore reduced raw-material cost.Simultaneously bamboo matter blade manufacturing efficiency height, initial outlay are low, and required producers are few.Come in the long term, bamboo matter blade has reduced the use of resin, and resin is the by-product of oil, and this has just reduced the risk of product price with the crude oil price fluctuation.
Once more, bamboo matter blade adopts the resin infusion process, and speed of production approximately is the twice of fiberglass blade, and needs labour force still less.
At last, help environmental protection.Nearly 50～80% weight is natural material (bamboo wood) in the bamboo matter blade product, in contrast to fiberglass blade, is beneficial to degraded more.
