The model utility content:
The utility model purpose provides a kind of sail formula wind energy power automatic transfer equipment, and is rational in infrastructure, reduces cost, and improves the wind energy conversion efficiency, solves the problems referred to above that exist in the background technique.
The technical solution of the utility model is:
A kind of sail formula wind energy power automatic transfer equipment, the wind-driven generator that comprises vertically arranged a plurality of sail and be attached thereto, said sail comprises a slice activity sail leaf and the sail rachis that matches at least, movable sail leaf is arranged on the sail rachis, the sail rachis is eccentric the setting on movable sail leaf, and movable sail leaf is divided into two-part that area differs in size.
The co-rotational circumference of sail, be divided into acting district and non-acting district by the wind-force direction, wind-force blows on the sail that is positioned at the acting district, and movable sail leaf hangs down, bear wind-force and drive sail and rotate acting, wind-force blows on the sail that is positioned at non-acting district, and movable sail leaf is parallel with wind, reduces resistance, do not bear wind-force, rotate with sail, turn to the acting of hanging down of the movable sail leaf in acting district, finish wind-force conversion and so forth.The sail rachis is eccentric the setting on movable sail leaf, movable sail leaf is divided into two-part that area differs in size, it is greatly different more that two-part area differs, the effect of acting is good more, but the weight of area major part should be to equal or less times greater than the weight of area smaller portions, both guaranteed to hang down at the movable sail leaf in acting district, guarantee that again movable sail leaf is parallel with wind in non-acting district because movable sail leaf parallel with wind mainly be the weight that the weight of dependence area smaller portions is come balanced area major part.
In order to increase the weight of movable sail leaf area smaller portions, can counterweight be set in the area smaller portions, the weight of balanced area major part; Perhaps increase the thickness of area smaller portions, gain in weight; The two-part that can also adopt different specific weight material creative activity sail leaf area to differ in size, the proportion of area major part is less, and the proportion of area smaller portions is bigger.
On the rotation path of movable sail leaf position-limited lever is set, the position of position-limited lever is adjustable, and the slewing area of assurance activity sail leaf is limited in 90 degree; Said position-limited lever position regulation mode can be regulated automatically by Single-chip Controlling, reconciles according to the wind speed size, and the angle that the greatly then movable sail leaf of wind speed rotates is big, more approaches parallel with the wind-force direction.
A plurality of movable sail leaves are set on a sail, and the arranged mode of a plurality of movable sail leaves is arbitrarily.
A plurality of sails can be set directly on the running shaft of wind-driven generator, drive the wind-driven generator rotation, can a plurality of sails be arranged on eminence by supporting frame.Also can be arranged on the rotating disk, turntable shaft connects wind-driven generator, drives the wind-driven generator rotation indirectly, is convenient to be arranged on wind-force larger areas such as sea, level land.For ease of the rotating disk rotation, rotating disk can adopt maglev mode to be provided with.
The beneficial effects of the utility model are:
1. the utility model can produce huge energy under the slow-speed of revolution, because wind-force and sail are positive impetuses, the area of sail itself can be very big; And the incision of sail, cut out also all in acting, the sail of acting facings the wind, and the sail that does not do work conversion automatically is parallel with wind, and solidity is bigger than very, can produce huge energy.
2. low wind speed (force one wind) can start, and high wind speed can change the movable sail leaf angle of acting automatically, also can normally move in high wind, guarantees stable rotating speed.
3. the utility model can replace the slurry formula wind generating unit in the background technique, relies on wind energy auto-control, running automatically, and rational in infrastructure, cost is low, wind energy conversion efficiency height.
