Abstract
The invention provides a composite wind energy vane which comprises a composite vane body and a vane root. The composite vane body is of a three-layer composite structure, and the middle layer is a vane supporting plate which is formed by a uniform metal sheet in a punching mode. The two sides of the vane supporting plate are provided with high abrasion resistance epoxy resin, and the composite vane is in a stream line shape. The vane root is fixed on the root portion of the composite vane, and a fixing hole is formed in the vane root. The composite wind energy vane has high strength, light and durable and is applied to a wind generator. The wind generator is started under the work station of low wind speeds, practical economic value is achieved, energy saving and environmental protection are achieved, and good social benefits are achieved.
Description
Technical field
The present invention is a kind of compound wind power blade, belongs to the renovation technique of wind power blade.
Background technique
At present, global energy is increasingly exhausted, and grobal environment worsens increasingly, and the exploitation of renewable energy sources is extremely urgent, and wind-power electricity generation is as current comparatively ripe renewable energy technologies, positive rapid growth under the vigorously supporting of national policy.But the utilization scope of wind-powered electricity generation still exists great restriction at present, main concentrating is distributed in the abundant area of the wind energy resourceses such as Xinjiang, the Inner Mongol and offshore islands, and the urban area large in the population density, power consumption is high, most of wind power product still cannot effectively be applied.Because it is higher that most wind power product starts wind speed, during low cruise, efficiency is low, cannot meet wind field operating mode work a little less than city.
Develop the wind-driven generator that is applicable to the weak wind field operation in city, must solve its low wind speed starting problem.Existing most of wind power blades generally adopt glass fiber reinforced plastics composite material, engineering plastics or metal section processing, and body is heavier, is unfavorable for that blower fan starts operation under low wind speed.Existing blade adopts sheet with equal thickness to make, and this blade manufacture is simple, and manufacturing efficiency is high, with low cost, but blade strength is difficult to be guaranteed.
Summary of the invention
For addressing the above problem, the invention provides a kind of compound wind power blade.
Concrete solution is: a kind of compound wind power blade, comprise composite blading and blade root, composite blading is three-layer composite structure, mesosphere is the stamping forming blade dunnage of uniform thickness sheetmetal, blade dunnage both sides are high abrasion epoxy resin, it is streamlined that composite blading is, and blade root is fixed on the root of composite blading, has fixed hole on blade root.
Further, described composite blading is used hot binding mode to be made by high abrasion epoxy resin, blade dunnage, high abrasion epoxy resin three-decker.
Further, the cross-section area of described high abrasion epoxy resin reduces to blade tip direction gradually near blade root position again.
Further, blade root is made by light-weight metal.
Wind power blade of the present invention has higher intensity, and light durable is applied to wind-driven generator, is convenient to wind-driven generator and starts under low wind speed operating mode, not only has practical economic value, and energy-conserving and environment-protective, has good social benefit.

Embodiment
A kind of compound wind power blade, comprise composite blading 3 and blade root 4, composite blading 3 is three-layer composite structure, mesosphere is the stamping forming blade dunnage 1 of uniform thickness sheetmetal, blade dunnage 1 both sides are high abrasion epoxy resin 2, it is streamlined that composite blading is, and blade root is fixed on the root of composite blading 3, has fixed hole 5 on blade root 4.
Composite blading 3 is used hot binding mode to be made by high abrasion epoxy resin 2, blade dunnage 1, high abrasion epoxy resin 2 three-deckers.
The cross-section area of high abrasion epoxy resin 2 reduces to blade tip direction gradually near blade root 4 positions again.
Blade root 4 is made by light-weight metal.
Wind power blade of the present invention has higher intensity, and light durable is applied to wind-driven generator, is convenient to wind-driven generator and starts under low wind speed operating mode, not only has practical economic value, and energy-conserving and environment-protective, has good social benefit.
