Description
Technical field
The utility model relates to a kind of wind generating unit, relates in particular to a kind of sail formula of waving wind generating unit that is used under the medium and small wind speed.
Background technique
In view of the continuous minimizing of ore fuel, the burning of ore fuel produces a large amount of pollutants in addition, people begin one's study one after another novel energy as an alternative product satisfy modernized demand, and one of wind energy new energy that beyond doubt wherein technology is comparatively ripe.The wind energy cleanliness without any pollution belongs to renewable energy sources, thereby blower fan is obtained development with rapid changepl. never-ending changes and improvements.
Yet, to make a general survey of various conventional fan and be not difficult to find, conventional fan is had relatively high expectations in view of starting wind speed, thereby is applied in outlying mountain area more, military post and the superior area of wind condition such as coastal; And some little wind and unsettled wind energy resources can not obtain collecting, utilizing, and therefore, blower fan novel, that adaptability is wideer will become the strong of conventional fan market and replenish.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming and defect that prior art exists, and a kind of sail formula of waving wind generating unit that is used under the medium and small wind speed is provided.
The purpose of this utility model is achieved in that
For solving the problem of how little wind being collected, the utility model from little grass light breeze rhythmically swing obtain inspiration, make full use of lever amplification principle, adopt high and narrow sail formula structure; Rotary wind-power electricity generations such as the utility model and traditional horizontal axis and vertical shaft have difference in essence, make full use of that general phenomenon---the oscillating motion of object in wind generated electricity, thereby make little wind obtain utilizing, and widen the Applicable scope of modern blower fan.
The utility model can be low to moderate reliably working under the startup wind speed of 1.0m/s.
Specifically, the utility model comprises base and control motor, storage battery and control system, pulley, gear, generator and the sensor laid on it;
Also be provided with swing sail frame, controlling rod, louvre type blade, pulley and guiding device and transmission shaft;
Base, pulley and guiding device are formed support and guide table, and implement device is the center with the column, the function of the positive angular positioning of facining the wind of self adaption;
Be connected with swing sail frame in base top by transmission shaft, be connected with the louvre type blade, the windward side is provided on swing sail frame top;
Sensor is installed on the bottom of swing sail frame, and the acceleration of swing sail frame is provided;
Sensor, storage battery and control system, control motor, controlling rod and louvre type blade are connected successively, realize the function that the louvre type blade opens and closes;
Swing sail frame, transmission shaft, gear, generator connect successively, realize that generator 8 utilizes the function of the reciprocal rotary electrification of wind energy.
Working principle of the present utility model:
The louvre type blade is in the close position under original state.
When extraneous wind front blew, the louvre type blade windward side on the swing sail frame produced wind pressure, and produce than high pulling torque power in the rotating shaft of swing sail frame by lever amplification principle, thereby drive swing sail frame skew, the wind-force acting, generator rotates generating.
When swing sail frame moved to the peak excursion angle, the too small axle of louvre type blade pass rotarily opened, and this moment is because blowing area reduces the backhaul under counterweight or spring action of swing sail frame.In the backhaul process, utilize specially designed " parallelogram " control structure can make the louvre type blade be in level at any time, reduce the resistance of backhaul with maximization.When swing sail frame turned back to the initial position of wind-force acting, the louvre type blade was closed, and carry out following one-period under the wind-force effect.
By " parallelogram " structure, can guarantee that swing sail frame is subjected to the windage minimum in return stroke, consumed energy is less; The little axisymmetric that the louvre type blade pass is crossed the central position is installed on the swing sail frame, makes the control motor to rotate the louvre type blade with less power consumption; By gear moment is converted into rotating speed and drives the unidirectional or two-way rotation generating of generator; Reach the leverage that produces by the transmission shaft mounting point by swing sail frame oneself height, the louvre type blade gross area, can realize that very little wind produces bigger moment, thereby realize low startup wind speed; Can realize that by the storage battery in storage battery and the control system control system need not external power input; Can realize monitoring by sensor and control system, and open and close the louvre type blade, reach the maximization that wind energy absorbs, and guarantee safety according to wind energy situation intelligence to swing sail frame pendulum angle, swing speed.
The utlity model has following advantage and good effect:
1. hang down under the wind speed in can working in;
2. have less startup wind speed, be low to moderate about 1m/s;
3. be applicable to the wind-power electricity generation under the medium and small wind speed.。
