Description
Technical field
The utility model relates to a kind of device of wind-power electricity generation, and concrete is a kind of wind-catching surface adjustable vane of wind power generation impeller.
Background technique
Nowhere no longer, wind has huge energy to wind on our earth, and people just utilize wind energy to change useful mechanical energy in time immemorial, is used for water lift, irrigation, flour milling, husks rice with mortar and pestle, and utilizes sail to promote boats and ships and advances.Nowadays people pay attention to this clean reproducible energy of wind energy more, and utilizing wind energy power is the special problems of paying attention to of people.Natural wind energy size and direction are capricious, and change very frequent, machinery as wind-driven generator then needs comparatively stable motion, because the blade wind catching area is fixed, usually when wind-force during less than specified generated energy wind speed, generator can not generate electricity at full capacity, even blade does not rotate, when wind-force may burn generator during greater than specified generated energy wind speed, people have made big quantity research on research adjusting vane windward side for this reason.
Summary of the invention:
Wind catching area for the realization blade of the present utility model can make things convenient for adjustment as required, and purpose simple in structure, proposes a kind of technological scheme of wind-catching surface adjustable vane of wind power generation impeller.
The technical solution of the utility model is, a kind of wind-catching surface adjustable vane of wind power generation impeller, it is characterized in that, the blade head of this blade is connected with vanes fixed, blade is rotatably connected by stator blade and moving vane, be provided with blade adjusting mechanism in the blade, described blade adjusting mechanism is connected with computer automatic control system.
The structure of described blade is: cross section be the stator blade two ends of V-arrangement by the rotating connection moving vane of hinge, end is by the rotating connection moving vane of hinge in addition for two moving vanes, two moving vanes end in addition interconnect by hinge is rotating; The blade head is fixedlyed connected with stator blade, and blade head profile is a smooth surface, and bit point is sealed by sealing surface; The structure of blade adjusting mechanism is: be provided with motor in blade end, motor is connected with transmission shaft, the a plurality of gears of connection that do not turn on the transmission shaft, inner chamber at stator blade is provided with fixedly connected supporting, supporting is provided with support roller, be provided with tooth bar between support roller and gear, the tooth bar outer end is rotatably connected with the hinge that is connected moving vane, and motor is connected with computer automatic control system.
The stator blade inner chamber of described V-arrangement is fixedly connected with support plate, and transmission shaft and support roller are connected on the support plate, and the stator blade angle beta=50-70 of V-arrangement °, the support plate right-hand member is to hinge distance L 〉=20 that are connected and fixed blade millimeter.
α=40-50 ° of described blade head bit point sealing surface and moving vane end angle.
In design during wind power generating set, general wind catching area is a definite value at present, is specified generated energy wind speed with the mean wind velocity of wind energy turbine set.In practice, the wind speed of most of times causes the year generating efficiency of generator set low less than specified generated energy wind speed in 1 year, and cost of electricity-generating improves.When extreme weather occurred wind speed greater than the generated energy wind speed, the lighter burnt generator, weight person even destruction wind power plant, and can only take peg or the stay cord that have are finished shutdown.Existing wind generator set blade is generally fixedly wind catching area, when wind speed hour, blade rotational speed is lower, even can not rotate; When wind speed was excessive, blade rotational speed was too high, may burn generator or destroy wind power plant.The wind-catching surface adjustable vane that the utility model adopts, blade is connected with moving vane by stator blade, is provided with blade control device in the blade.The structure of described blade is: cross section is stator blade two ends and 4 moving vanes that are rotatably connected by hinge of V-arrangement, make the cross section of blade become enclosed cavity, stator blade and moving vane combination can make the cross section of blade be changed to triangle by rhombus, when the cross section of adjusting blade is triangle, the wind catching area maximum of blade, when the cross section of adjusting blade was rhombus, the wind catching area of blade diminished.The structure of blade control device is: be provided with motor at blade one end, motor is connected with transmission shaft, connects a plurality of gears on the transmission shaft, is provided with tooth bar between support roller and gear, the tooth bar outer end is connected with the hinge of 4 moving vanes centres, and motor is connected with computer automatic control system.Computer automatic control system sends rotation command to motor as required, and motor rotates, and driven gear rotates, the pulling tooth bar is reciprocating, owing to tooth bar is connected with hinge, when tooth bar outwards moves, it is protruding to promote moving vane, makes the wind-catching surface evagination, and wind-catching surface reduces; When tooth bar inwardly moves, it is inside to spur moving vane, makes wind-catching surface gradually become the plane by evagination, and wind-catching surface increases, when wind-catching surface is two moving vanes when being parallel to each other, and the wind catching area maximum.For preventing two moving vane indents, the utility model extends the moving vane place outside support plate is designed to, and plays the position-limiting action to moving vane.For making blade capture more wind energy, the utility model is provided with and the blade head in the blade outer end, and to closing up, blade head profile is a smooth surface to blade head profile by V-arrangement two N-Side surfs of stator blade, the bit point sealing, blade head bit point sealing surface and moving vane end have angle.The utility model is simple in structure, reasonable in design, and the wind catching area of blade can be adjusted as required easily, guarantees that blade can safe and efficient work.
