Abstract
The utility model relates to a kind of wind electricity blade, if blade shell, described blade shell is longitudinally set to blade root, blade, blade tip, described blade shell front is provided with blade face windward, and described blade shell inside is provided with leaf case beam, the rigidity on described leaf case beam support blade face windward, described blade is divided into blade back, leaf basin, described blade design becomes the galleyproof type leaf type of distortion, and blade changes into three dimendional blade along exhibition vector product, and described blade shell inside is the structure of cavity.The utility model wind electricity blade alleviates leaf weight, improve intensity and the anti-fatigue performance of blade, effectively improve the efficiency that blade accepts wind energy, employing twisted blade designs, make blade distortion several angle along its length, make blade all be in optimum angle of attack state everywhere, obtain best lift.
Description
Technical field
The utility model belongs to one and to have an effect power generating equipment, particularly a kind of blade of wind-driven generator.
Background technique
Due to worsening shortages and the environmental pollution problem that brings thereof of fossil energy (oil, coal etc.), the exploitation of clean reproducible energy have become the common recognition of the mankind, cause growing interest and the attention of countries in the world.Wind-power electricity generation is a kind of clean reproducible energy of current most commercial value, development abroad comparatively early and technology maturation, China's Wind Power Generation Industry development relative delay, but be classified as renewable energy sources developing focus after 2005 and give great support.Research and develop both at home and abroad at present, create multiple wind-driven generator miscellaneous.
Because natural wind regime is changeable, in rotation, the attitude of wind electricity blade is difficult to all produce best aerodynamic efficiency with wind regime change.When wind speed is fierce or wind vector is violent, inappropriate attitude windward makes pneumatic equipment blades made easily damage, and excessive power also can cause damage to wind-driven generator main frame simultaneously.People take the attitude that various ways carrys out adjusting vane, to adapt to wind regime situation of change; And along with blade radius increasing, adapt to the incoming flow situation then great energy ezpenditure of needs by blade integral around main axis.
Model utility content
The purpose of this utility model is to solve the problem, and proposes a kind of wind electricity blade, and this wind electricity blade alleviates leaf weight, improves intensity and the anti-fatigue performance of blade, effectively improves the efficiency that blade accepts wind energy.
The purpose of this utility model is achieved through the following technical solutions: wind electricity blade, if blade shell, it is characterized in that: described blade shell is longitudinally set to blade root, blade, blade tip, described blade shell front is provided with blade face windward, described blade shell inside is provided with leaf case beam, the rigidity on described leaf case beam support blade face windward, described blade is divided into blade back, leaf basin, described blade design becomes the galleyproof type leaf type of distortion, blade changes into three dimendional blade along exhibition vector product, and described blade shell inside is the structure of cavity.
Further, in described blade shell, longitudinally axis is provided with a lightning protection copper strip and connects sudden strain of a muscle net, and described lightning protection copper strip connects sudden strain of a muscle and is provided with multiple arrester on the net.
Further, described blade shell inside is perfused with glass fiber reinforced epoxy resin, and described blade shell surface is provided with corrosion-resistant finishes.
The utility model adopts twisted blade design, makes blade distortion several angle along its length, makes blade all be in optimum angle of attack state everywhere, obtain best lift; Consider during design that the aerodynamic force that blade is accepted can be assigned on whole blade fifty-fifty, also different aerofoil profile chord lengths is optimized.Blade material is glass fiber reinforced epoxy resin, adopts resin vacuum introducing technology, has that bonding strength is high, good toughness, corrosion-resistant, fatigue performance good, the feature that fracture elongation is high, can with good the mating of reinforcing material.The excellent properties such as blade coatings has corrosion protection, desertification dirt, uvioresistant, ageing-resistant, resistive connection freezes, are convenient to high-altitude cleaning simultaneously.Blade profile is high aerodynamic configuration blade, and blade surface roughness has strict restriction specification, and blade surface degree of finish is very high, and under the cleaning function brushing with rainwater of wind, dust dirt not easily adheres to, and blade surface can keep clean substantially.Blade has safe lightening protection installation, and this facility and cabin lightning conductor system are connected.
Accompanying drawing explanation
Fig. 1 is leaf shell internal structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model leaf shell windward side;
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: see accompanying drawing 1,2, wind electricity blade, if blade shell 1, described blade shell is longitudinally set to blade root 2, blade 3, blade tip 4, and described blade shell front is provided with blade face windward, described blade shell inside is provided with leaf case beam, the rigidity on described leaf case beam support blade face windward, described blade is divided into blade back, leaf basin, and described blade design becomes the galleyproof type leaf type of distortion, blade changes into three dimendional blade along exhibition vector product, and described blade shell inside is the structure of cavity; In described blade shell, longitudinally axis is provided with a lightning protection copper strip and connects sudden strain of a muscle net 5, and described lightning protection copper strip connects sudden strain of a muscle and is provided with multiple arrester 6 on the net; Described blade shell inside is perfused with glass fiber reinforced epoxy resin, and described blade shell surface is provided with corrosion-resistant finishes.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.And thus the apparent change of extending out or variation be still among protection domain of the present utility model.
