Abstract
The oblique backstroke wind wheel swing speed limit method of wind motor.
This method is that the wind wheel of wind motor and deflection mechanism are placed on the clinoplain, the wind wheel rotating shaft axis is wound all the time perpendicular to the axis on inclined-plane swing, and wind wheel upwards turns at a slant.Depart from wind direction, reduce rotating speed,, realize the protection of wind motor until stopping fully.
Description
The present invention is relevant with the method for wind wheel swing speed limit with wind motor.
Adopt the wind motor of wind energy as power, because the unstability of wind speed, wind motor must have reliable safety system, so that when wind speed is very high, makes wind motor reduction rotating speed or shuts down the protection wind energy conversion system.
In order to reduce the wind energy conversion system rotating speed or to stop its running, wind wheel swing, paddle deflection have extensively been adopted, methods such as air damping and mechanical brake.The present invention is the improvement to existing wind wheel swing method.
Existing wind wheel swing method has two kinds: lateral deviation is changeed wind wheel and is upward deflected.Major technique is that the whole rotation of wind wheel departs from wind direction when wind speed surpasses fixing speed.Promptly the wind wheel spin axis rotates around vertical shaft at horizontal plane in wind wheel lateral deviation method; Upward deflecting in the method at wind wheel, be that the wind wheel spin axis is rotated around horizontal axis in vertical guide, but these two kinds of methods has some shortcomings and narrow limitation:
When lateral deviation is changeed wind wheel, the speed limit instability, simultaneously, because the wind wheel running shaft is swung in horizontal plane, is in the same plane, when wind wheel deflects to a certain angle with wind direction all the time, because the variation of wind direction, may make wind wheel down with the wind positive, thereby cause the unexpected accelerated service of wind wheel, damaged blade easily.Therefore this mode is often used in the wind energy conversion system of large-sized low-speed.
Upward deflect wind wheel, because the wind wheel rotating shaft is vertical with wind direction, so protection is reliable.But after the nose-up speed limit, when wind speed diminishes, particularly diminish suddenly, head is when turning down, and impact is very big, damages parts easily.Blower fan is faced upward simultaneously, and movement range is big, and space is big, so this mode often only is used for small wind engine.
The purpose of this invention is to provide the method for a kind of wind wheel swing, change speed limit instability in the past, swing jiggly problem with the restriction wind speed round.
The method of restriction wind speed round provided by the invention is when wind speed surpasses limit value, wind wheel under the effect of deflection mechanism, depart from positive facing the wind to.And this departing from is by wind motor and deflection mechanism are placed on the clinoplain, and when departing from, in a clinoplain, the axle that winds perpendicular to clinoplain rotates the running shaft of wind wheel all the time, and wind wheel is then faced upward along the inclined-plane side, departs from positive wind direction.
Method provided by the invention not only can make wind wheel deflection righteous style and practice face, has reduced the wind wheel wind-exposuring area, has reduced rotating speed.And tiltedly face upward when being biased to a certain position when wind wheel, no matter how wind direction changes, because the inclined-plane exists, wind wheel becomes certain inclination angle with wind direction, can not cause positively facing the wind, state that protection is slipped up.Deflection simultaneously is to carry out on the inclined-plane, and the stable action amplitude is little, and the space of motion is also little, therefore is applicable to small-sized and bigger wind energy conversion system.
Description of drawings:
Embodiments of the invention below will further be described by the symbol in accompanying drawing and the accompanying drawing.
Wind motor and deflection mechanism that Fig. 1 (A), (B) expression are settled by method of the present invention.
Fig. 2 (A), (B), (C) are illustrated in three kinds of deflection situations under the different wind speed.
Embodiment's explanation:
Among Fig. 1, motor (2) connects and impeller (1) is installed on the flat board (3), and dull and stereotyped (3) by the axle (5) perpendicular to flat board, and the inclined-plane of bearing (6) and headstock (7) links, and is placed on the inclined-plane.The flat board (3) that tilts rotates on the inclined-plane together with the axis that motor (2) impeller (1) can wind the inclined shaft (5) perpendicular to the inclined-plane.Inclined shaft (5) has a throw of eccentric ∑ with the projection of electrical axis on clinoplain.So that wind wheel is under the positive pressure of wind, inclined shaft produces deflecting torque relatively.And make wind energy conversion system return deflection, the size of the wind speed when equilibrium establishment when deflecting to a certain position and wind energy conversion system begin deflection is formed by the bearing pin (4), connecting rod (8) and the compressible spring (10) that link with tilt flat plate (3) and at eccentricity pressure mechanism and gravity boosting mechanism that the reciprocating guide rod in guide sleeve (11) lining (9) that is fixed on the headstock is formed.At wind speed during greater than specified value, the resultant moment of force of the moment that the deflecting torque of wind wheel and eccentricity pressure mechanism and gravity produce makes wind wheel deflection, leave positive facing the wind to, the limit position of deflection is to make wind wheel substantially with the wind, and the angle between the running shaft when this moment, wind wheel running shaft and front facingd the wind is 90 °.The angle that designs inclined-plane and horizontal plane simultaneously is when the tilt limit position, and the wind direction flip-flop facings the wind wind wheel, but because the existence of this angle is arranged, wind speed round can not surpass regulation numerical value.
Claims (4)
1, a kind of wind wheel swing is with restriction wind motor wind speed round, to the method for security protection of wind motor.It is characterized in that in the working procedure that wind motor is protected, the running shaft of wind wheel is swung all the time in a plane of inclination, wind wheel is faced upward along the inclined-plane side all the time, depart from wind direction, carry out speed limit, realize the protection of wind motor.
