Description
Technical field
The utility model relates to a kind of oblique axis type windpower generating unit.
Background technique
Along with the environmental problem that conventional energy resource brings is outstanding day by day, wind-powered electricity generation more and more is subjected to people's attention as a kind of clean energy resource, has experienced the test of long-time running, progressively develops into the market structure based on horizontal axis and vertical shaft fan.The horizontal axis rotation speed of fan is fast, but it is higher relatively to start wind speed, and is low to the utilization ratio of gentle breeze; Vertical shaft fan has bigger detent torque since when revolution the resistance that produces, tip-speed ratio is low, in size, under the certain condition of weight and cost, the output power that provides is low.Although Da Lie lift vertical shaft blower fan efficient is higher relatively, have can not self-starting shortcoming.In addition, also there is the problem of high-altitude maintenance difficult in existing blower fan.
Summary of the invention
The purpose of this utility model, be to design a kind of big detent torque that has, be not subjected to drag effects during revolution and produce powered, and higher gentle breeze utilization ratio arranged, rotating speed is also higher, the wind generating unit that lower investment and operation expense (being convenient to ground maintenance) arranged, this device also will have certain sight.
The technical solution of the utility model is, oblique axis type windpower generating unit, it comprises fan blade 1, generator 2, gearbox 3, break 4, batter post bearing 5, cable 6, break linkage rod 7, to wind-powered electricity generation machine 8, to wind gear 9, tail vane 10, gearbox 12, support 14 and pylon 15, its feature: fan blade 1 is that its cross section becomes wing petal-shaped handle of the Dipper formula fan blade, and its sheet number is that multi-disc and global design become flower shape; Unit comprise blade structure whole be inverted be suspended on cross-arm formula support tower front side on the wind framework and the centre-of gravity shift suspension point; Its running shaft is faced upward 10～89 ° down with the wind; Above-mentioned to also being provided with a pair of limiting stopper 11 on the wind framework;
Also be provided with in this device and comprise the center towards top sheave 13, the unit suspension point support pulley 13 ' and wire rope 16 at interior unit elevator mechanism, land maintenance in order to unit.
During concrete enforcement, the sheet number of fan blade 1 is 5, and the angle that unit and blade structure running shaft are faced upward down with the wind is 45 °.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a lateral plan.
Fig. 2 is same embodiment's a front view.
Among the figure, 1-fan blade, 2-generator, 3-gearbox, 4-break, 5-batter post bearing, 6-cable, 7-break linkage rod, 8-to the wind-powered electricity generation machine, 9-to wind gear, 10-tail vane, 11-limiting stopper, 13-center towards top sheave, 13 '-the unit suspension point supports pulley, 14-support, 15-pylon, 16-wire rope.
Embodiment
Referring to Fig. 1 and Fig. 2, this is to have 5 fan blades and unit to comprise face upward down with the wind 45 ° oblique axis type windpower generating unit of blade structure running shaft integral body.Wind blows from substantially horizontal, when the cross section becomes wing, when operating at upward position for the fan blade of petal-shaped handle of the Dipper formula structure, the front can accept the direct Thrust of wind, and when fan blade turns round to other positions, the lift that fan blade is produced by wind promotes the fan blade motion, and like this, fan blade is converted to lift by accepting thrust, be converted to thrust by lift again, wind-force promotes fan blade all the time and rotates around its running shaft.Because unit comprises blade structure integral body and has faced upward 45 ° down with the wind, and fan blade changes 45 to axle and installs, so, fan blade from horizontal position when up (45 °+45 °=90 °) vertically-supplying air when, fan blade is descending from horizontal position (45 °-45 °=0 °) Parallel airflow to.Therefore vertically-supplying air has the characteristics of breeze wind to obtaining maximum moment; And revolution the time has the fan blade in wing cross section that substantially horizontal wind is had the preferable angle of attack, so to fan blade generation lift, make the blower fan can quick rotation.So the utility model has higher efficient again.Because unit comprises whole inversion of blade structure and is suspended on the wind framework and the centre-of gravity shift suspension point, so when wind speed was excessive, unit comprised that blade structure can integral body faces upward, thereby changes the angle of fan blade to wind direction, produce rightabout rotational resistance, reach the purpose of braking speed governing and protection; And when wind speed diminished, the effect of gravity can make unit comprise that blade structure resets again.Comprise the unit elevator mechanism of center towards top sheave, unit suspension point support pulley and wire rope owing to also be provided with in the device, so can unit integral body be put into ground by the ground winch in case of necessity, maintaining is very convenient like this.
