Working procedure of the present invention is:
With reference to Fig. 5 illustrate, if: this wind wheel is 6 straight plate wind wheel blade D, and 0 degree position is D1, the 60 degree of positions that turn clockwise is D2,120 degree of positions be D3,180 degree of positions be D4,240 degree of positions be D5,300 degree of positions be D6; Wind-force, from 0 degree of angular direction, is blown over to 180 degree of angular direction.
When straight plate wind wheel blade D is in D1 position, each protruding recesses coincide corresponding with the first side plate C-5-1 on pylon C and the second side plate C-5-2 on straight plate wind wheel blade D1 baffle plate, make straight plate wind wheel blade D1 under the action of the forces of the wind, among the grooved slideway that can enter pylon C smoothly, the first bearing pin C-8 also enters in D-5 groove simultaneously; Enter in the grooved slideway process of pylon C at straight plate wind wheel blade D1, spacing card C-23 will be oppressed to move in spacing draw-in groove C-26 simultaneously, 3rd gear C-17 and the 3rd sprocket wheel C-12 are pushed away the engagement with the first gear C-15 by support C-14 by spacing card C-23, also push subtend the 4th gear C-18 and the 4th sprocket wheel C-13 to engagement with the second gear C-16 simultaneously.While straight plate wind wheel blade D1 carries out above-mentioned action, each protruding groove corresponding with the first side plate C-5-1 and the second side plate C-5-2 of subtend straight plate wind wheel blade D4 baffle plate also overlaps simultaneously, this blade is subject to the effect of wind-force by the grooved slideway screwing out this pylon C, second bearing pin C-9 is also about to depart from D-5 groove, this side spacing card C-23 is pressure relief along with the rotation of straight plate wind wheel blade D4, is subject to the thrust of the spacing card C-23 of subtend simultaneously and makes the 4th gear C-18 and the 4th sprocket wheel C-13 and the second gear C-16 be in engagement.Because 0 degree to 180 degree clockwise three straight plate wind wheel blades are all among the grooved slideway of corresponding pylon C, can not rotate relative to pylon C, and 180 degree to 0 degree clockwise three straight plate wind wheel blades have all broken away from the constraint of pylon C grooved slideway, rotate relative to pylon C under the action of the forces of the wind, thus the blowing area sum of 0 degree to 180 degree clockwise three straight plate wind wheel blades, be far longer than the blowing area sum of the straight plate wind wheel blade of opposite side three, thus this wind wheel is rotated in a clockwise direction under the action of the forces of the wind.Along with the rotation of wind wheel, straight plate wind wheel blade D4 is subject to wind action, together with the second wind wheel blade axle C-7 relative to pylon C in being rotated counterclockwise, second gear C-16 that rotarily drives of the second wind wheel blade axle C-7 rotates, second gear C-16 rotarily drive the 4th gear C-18 and the 4th sprocket wheel C-13 rotates simultaneously, the first chain C-19 that is rotated through of the 4th sprocket wheel C-13 walks around the first sprocket wheel C-10 and pulls the first bearing pin C-8 outwards to slide, first bearing pin C-8 mono-aspect pulls straight plate wind wheel blade D1 to slide to the direction away from main shaft E by D-5 groove, the second bearing pin C-9 is pulled to slide to the direction of main shaft E by the 3rd chain C-21 on the other hand.Along with the continuation of wind wheel rotates, straight plate wind wheel blade D4 continues to be rotated counterclockwise, and all the time with wind direction keeping parallelism, straight plate wind wheel blade D1 is pulled by the direction of continuing to away from main shaft E.When straight plate wind wheel blade D4 rotates to 0 degree of position, blade D1 rotates to 180 degree of positions.Now, this transmission device will carry out above-mentioned motion in the other direction.In like manner, the motion mode of straight plate wind wheel blade D2 and straight plate wind wheel blade D5, straight plate wind wheel blade D3 and straight plate wind wheel blade D6, identical with above-mentioned motion mode.
According to above-mentioned working procedure, two on same straight line straight plate wind wheel blades are subject to the driving of same transmission device, and its motion is accordingly carried out simultaneously.In the running of reality, if wind direction changes, as shown according to Fig. 5, if the wind comes from, direction becomes 330 degree of directions, then the straight plate wind wheel blade moving to 330 degree will be subject to the effect of wind-force, accelerates to be rotated counterclockwise, also enter the grooved slideway of this pylon C fast in advance, the straight plate wind wheel blade that subtend is in 150 degree of angles also can enter rotary state thereupon in advance, thus makes in Fig. 50 degree of Angle Position turn to the direction of the wind comes from, and is namely rotated counterclockwise 30 degree to 330 degree of original positions; If the wind comes from, direction becomes 30 degree of directions of Fig. 5, the straight plate wind wheel blade then moving to 0 degree of Angle Position will be subject to the effect of wind-force and delay the grooved slideway that 30 degree of angles enter this pylon C, the straight plate wind wheel blade of subtend also can delay 30 degree of angles thereupon and enter rotary state (entering rotary state when 210 degree of angles of Fig. 5), thus make in Fig. 50 degree of Angle Position turn to the direction of the wind comes from, namely turn clockwise 30 degree to original one o'clock position.Illustrating thus, wind wheel of the present invention, along with direction of the wind comes from, can automatically regulating the working state of itself, without the need to adjusting its weather side by empennage.
In addition, in the present invention in mode of execution process, be certain to run into the state stopped operating because of calm, now, arrange an automatic control system Z in the below of many groups pylon C of main shaft E, automatic control system Z is for controlling the reversion of main shaft E.This wind wheel is in real work, and when there is the state stopped operating because of calm, after this wind wheel stops operating, if wind direction is from 180 or less than normally blow to wind wheel in 180 degree of any directions, this wind wheel will reverse.Automatic control system Z is exactly when reversion tendency appears in wind wheel, automatic startup braking system prevents this wind wheel from reversing, starting electrical machinery forces the clockwise slow circumvolve of main shaft E simultaneously, that is 0 of this wind wheel of forced motor degree of position is allowed to turn to the direction of the wind comes from, more than main shaft E 90-degree rotation when less than 180 degree, 0 degree of Angle Position of this wind wheel will be under the action of the forces of the wind, auto-steering be the wind comes from direction, now automatic control system Z departs from automatic control state, so just can guarantee wind wheel automatic rotation with the wind.
The function and structure of this automatic control system Z can be realized by the common practise of prior art and related domain, therefore the present invention is not repeated.
Although the present invention discloses as above with preferred embodiment; but and be not used to limit of the present invention; those skilled in the art can also do other changes in spirit of the present invention; and be applied in the NM field of the present invention; certainly, these changes done according to the present invention's spirit all should be included in the present invention's scope required for protection.
