Abstract
The utility model relates to a wind engine capable of changing blowing area of blades. The blade frames of the utility model are radially equispaced around a rotary shaft and fixed with outer shafts into an integrity. The centre of the integrity is provided with a cylinder which can rotate corresponding to the integrity. The blades on each blade frame is towed by a cable or a chain; both ends of the cable or the chain is fixed to the cylinder after reeling pulleys or sprockets arranged on the blade frame. When the cylinder rotates forward or backward, the blades can move on the blade frame and the exterior surface of the cylinder by towing of the cable or the chain. When the blades move upward, the blowing area of blades decreases, inversely the blowing area increases. The changing of the blowing area of blades can solve the problem that the rotation speed of the rotary shaft of the wind engine is uneven under different wind powers.
Description
The utility model relates to a kind of its rotating shaft and the heavy straight device that utilizes wind-power electricity generation of wind direction.
The existing wind motor that is used to generate electricity is to be made of rotating shaft that links with generator amature and uniform blade on it substantially.The moment that natural wind produces when promoting blade makes rotating shaft drive the generator amature rotation and is generated electricity.When wind-force was big, the rotating speed that rotor obtains was just high, otherwise promptly anti-.But if generator amature can not rotate with constant speed, then the output power of generator just can not be stablized.Yet natural wind is not balanced continuing, and often big a burst of, little a burst of, this just makes the rotating speed of wind motor rotating shaft fluctuated, causes the output of generator not stablize then.
The purpose of this utility model is to provide a kind of wind motor that can change the blade blowing area, by the variation of blade blowing area, makes the suffered wind-force of engine blade produce constant moment, realizes the speed governing of motor.
The utlity model has rotating shaft, blade rack, blade rack is no less than 3 fans and is radial equipartition around rotating shaft, and is fixed into one with rotating shaft, in the central authorities of the integral body that is made of rotating shaft and blade rack, one cylinder is arranged, have retainer between cylinder and the described integral body; Be positioned in the rotating shaft of cylinder center a braking motor is housed, a pair of gear rack that is meshed links cylinder and braking motor; On the inside and outside strut of every fan leaf support, be equipped with pulley (or sprocket wheel) in upper and lower end, upper and lower hawser (or chain) is walked around pulley (or sprocket wheel) respectively, and its two ends are fixed on the cylinder; Blade is arranged in order on each blade rack the same side hawser (or chain), and each links with it in upper and lower end.When wind-force changes, the control system that is made of input, processing, instruction output that is connected between generator output end and the braking motor makes braking motor do corresponding the rotation, drive cylinder immediately and turn an angle with the cog tooth bar of engagement of braking motor, being fixed on hawser (or chain) on the cylinder drives its upper blade and is moved, the result that blade moves, the distance of blowing area and wind-force effect is changed, thereby the moment of rotating shaft rotation is changed, the rotating speed of rotating shaft also changes; When wind-force was relatively stable, instruction stopped braking motor, and under braking state, cylinder can not rotate relative to blade rack, and blade is not subjected to displacement, and the blade blowing area does not change, and the rotating speed of rotating shaft does not also change.Under the continuous instruction of control system was adjusted, the moment that the suffered wind-force of the blade that moves produces can make rotating shaft be stabilized on the rotating speed of a certain setting, realizes the function of speed governing.
The utility model adopts the structure that blade is moved, and realizes the variation of blade blowing area, and not only speed adjustable range is big, also can realize stepless speed regulation; Under situations such as maintenance, typhoon, hail, blade all is received on the cylinder, can conveniently work again, reduce and destroy.
Talk an embodiment below in conjunction with accompanying drawing.
Fig. 1 is the axial sectional view of the utility model (B-B).
Fig. 2 is the utility model radial cross-section (A-A).
4 fan leaf supports 1 are cross are fixed in the rotating shaft 2, every fan leaf support is the frame type, in upper and lower end pulley 3 is installed on its inside and outside strut, and the pulley on the medial branch strut is two series connection.Cylinder 4 is positioned the central authorities of the integral body that blade rack 1 and rotating shaft 2 constituted by retainer 5, toothing bar 6 on the inwall of cylinder 4, and braking motor 7 is fixed in the rotating shaft 2 by bearing 8, and the gear 9 that is meshed with tooth bar is installed on the output shaft of braking motor 7.After steel cable 10 is walked around pulley 3, its two ends are fixed on the cylinder 4 with screw 11, blade 12 is arranged in order, link in upper and lower end and steel cable 10, during connection, blade 12 is positioned on each blade rack the same side steel cable.
