Description
Technical field
The present invention relates to a kind of Wind Power Utilization technology, particularly relate to a kind of wind generating unit.
Background technique
According to rate for incorporation into the power network and the cost of electricity-generating of current wind-powered electricity generation, investment wind energy turbine set does not have attraction force.The development of Wind Power In China industry is mainly driven by government, and the Committee of Development and Reform stipulates 2010 in " planning of renewable energy sources Long-and Medium-term Development " and the non-water power renewable energy power generation rights and interests installation total capacity that has of large-scale electricity power enterprise (rights and interests generator installation exceedes 5,000,000 kilowatts) in 2020 should reach the more than 3% and 8% of its rights and interests generator installation total capacity.Just because of the mandatory quota of government, drive large-scale electricity power enterprise to carry out wind-powered electricity generation investment.Wind-power electricity generation is environmental friendliness not only, renewable, and cost is low, the construction period is short, do not have fuel limit, is the field most in new energy with development potentiality.The year two thousand twenty, conservative estimation can realize the electric motor power of ten thousand kilowatts of 8000-10000, becomes the third-largest main flow energy of the thermoelectricity that continues, water power.
Visible, wind-powered electricity generation product industry has had good opportunity to develop at present, and this scape has attracted more investment and financing persons' concern.But traditional blower fan has following deficiency:
The conversion efficiency of 1 wind energy is lower; The technical merit of 2 state's inner blowers has much room for improvement, and oeverall quality still exists larger problem, and the domestic component quality of part does not still pass a test; 3 conventional fan are in order to increase very large that the lifting surface area of wind often makes, and corresponding its supporting blower fan pillar etc. are also very huge, and whole like this blower fan manufacture cost is very high, and high to fan blade material requirements, otherwise in high wind, be easy to blow bad.Although conventional fan mostly adopts special material at present, still when wind-force rank is larger, often occur that Fan Equipment occurs that situation about damaging occurs.
Summary of the invention
The object of the invention is to provide a kind of low cost of manufacture, and the conversion efficiency of wind energy is high, not affected by wind direction, and whole equipment unit is without using special material, all can just can meet the requirements of wind generating unit with common material.
For realizing goal of the invention, the technical solution used in the present invention is: a kind of wind generating unit, comprise vane group, radome, central shaft, vane group is comprised of two or more blades and vane group is connected with central shaft, central shaft is connected with alternator shaft or accumulation of energy transfer mechanism, radome is hollow semi-cylindrical shape, at the top of radome and the side circular arc part of radome, respectively there is a wind direction to adjust plate, in the bottom of radome, there is the mechanism of a pivoting support, or have in a groove and be evenly distributed with ball circular trough, radome can be adjusted mobile by 360 degree around central shaft according to the change of wind direction in fixing pivoting support or other circular trough mechanisms.
Described central shaft is connected with semicircular base diameter center with the semi-circular top diameter center of radome by a roller bearing or ball bearing respectively.
Described radome is not connected with central shaft with vane group, between radome and vane group and central shaft, keep the gap of 0.1 ~ 5cm, vane group and central shaft and motor or accumulation of energy transfer mechanism maintain static, and whole radome does 360 degree adjustment around vane group and central shaft according to wind direction and moves.
Described blade is half indent open circles ball-type blade or indent rectangle type blade.
Blade of the present invention with the central shaft being connected with blade in rotary course, vane group has a semiosis to enter radome, blade when rotating with the wind, in radome outside, rotate, and enter radome and be rotated further in radome being about to while rotating against the wind, when forwarding to radome outside, blade is still in state with the wind. and wind is all the time at the outside of radome promotion blade rotary, and blade in contrary wind rotary course owing to having entered radome, therefore be not subject to drag effects against the wind.
The present invention adjusts plate at the wind direction of the top of radome and the side circular arc part setting of radome, is cross section and the wind direction keeping parallelism of guaranteeing the hollow semicolumn of radome.
The present invention is at the swirl gear of the bottom of radome, or with the circular trough of ball, to guarantee that radome can be in change of the wind, at wind direction, adjust under the effect of plate, radome can rotate freely adjustment by 360 degree, till adjusting to the cross section of hollow semicolumn and the angle of wind direction keeping parallelism shape of radome always, no matter how wind direction changes like this,. vane group can enter radome in contrary wind rotary course, be not subject to drag effects against the wind. so greatly improve rotational speed and the dynamics of vane group, greatly improved the utilization ratio of wind.
The conversion efficiency of wind energy of the present invention is very high, blower fan manufacture cost is lower, whole equipment unit all can just can reach requirement with common material, without using special material, and be not easy to occur device damage phenomenon, and reach breeze start-up, noiseless, anti-more than 12 grades typhoon, the premium properties that is not subject to that wind direction affects etc., can for various differences, there is in a large number the environment of wind, power generation system take it as main foundation, has electric power stable output, to the advantage such as environmetal impact is minimum.
