Abstract
The invention relates to a low wind speed vane-type wind driven generator capable of automatically adjusting the direction, which belongs to the field of energy resource and wind power generation. A vane of the prior wind generating set is rigidly connected with most of a rotating shaft, and the posture of the vane in the rotating process is unchanged. The product has a first characteristic that the cross section of the vane is designed into a wing shape, so that wind blows through the cross section and the front side of the vane to generate larger tangential thrust and positive driving force which work together to drive a main shaft of a draught fan to rotate. The second characteristic of the product is to skillfully utilize wind force; when the vane is positioned in a windward area, the windward area of the vane is the largest; and a wind stopping area automatically rotates the vane by use of the wind force, so the resistance is the smallest. Therefore, the force lifting principle of the vane shape is utilized, and the thrust principle of the vane surface is utilized.
Description
One, technical field
Affiliated technical field: the energy, wind-power electricity generation
Two, background technique
Green (renewable) energy is the emphasis of research and development in the present age, and efficiently utilizing wind energy is the target that people pursue all the time.
This product can reach the purpose of efficiently utilizing wind energy on principle and technical pattern.The core technology of this request for product patent is to utilize wind direction to make fan blade adjust attitude automatically.All the time make the resultant moment of force of blade in the district that facings the wind, adjust the fan blade attitude automatically by wind direction, make fan blade affact the resistance torque minimum of fan shaft in Resistance Level to fan shaft generation lifting force moment and Driving force moment.This patent is used wind-force and is adjusted the blade attitude automatically, and the one side blade produced tangential thrust when blade was facingd the wind, and has made full use of the thrust of facining the wind on blade blade face on the other hand again.This is the unique distinction of this product, and it has not only made full use of wind energy, and utilizes the better effects if of wind energy under low wind speed.This has not only improved wind energy utilization, has also reduced the startup wind speed simultaneously.
Three, summary of the invention
This product mainly shows in the pneumatic conversion of blower fan, presses five equilibrium at the axial fan hub periphery 5～7 blades are installed.Blade is contained on the pole, drives main axis rotation by pole.Blade inlet edge is aimed at when the wind comes from direction, has the blade above half to be in the district that facings the wind so all the time.Distinguishing the wind-force effect that blade is subjected to incoming flow down with the wind, not only vane foil can produce along the tangential force (lift) in week, and the blade face also wind-engaging try hard to recommend power, produce head-on thrust.Distinguishing against the wind, the effect of blade wind-engaging power can produce resistance.Because blade automatic direction regulating under the wind-force effect also makes drag area greatly reduce.This makes blade be in the resistance minimum position all the time.
Above-mentioned design can make the blower fan moment of rotation increase greatly, thereby has improved power coefficient.

Five, embodiment
One of core component of wind-driven generator is the pneumatic part of blower fan, promptly is to be the part of mechanical energy with wind energy transformation, and this product has improved wind energy utilization, has improved wind energy utilization especially under low wind speed.
The power generation system of this wind-driven generator is made up of critical pieces such as the pneumatic system of automatic steering blade formula (air operated machine), permanent magnetic DC generator, engine controller, inverters, and the electric energy that generator sends becomes the electric energy that the user can directly use after control, rectification.May command charging and discharging of accumulator in addition, and can play the effect of protection generator.
Claims (4)
1 automatic direction regulating low wind speed blade type wind power generator.
2, to utilizing wind direction to make the blade attitude be in the working principle and the mode of structure of the state of the most reasonable, science all the time.
3, the rotatable structural principle of low speed wing of wind-driven generator employing.
4, to using wind-force fan blade is rotated automatically.
