In this example, 12 release angle of accumulation of energy torsional spring is 43 °, and release time is about 2s.
The present invention is divided into two kinds of operating modes: output is concentrated in high-speed direct-drive and low speed accumulation of energy.
The principle of high-speed direct-drive is as follows:
Input shaft 17 is rotated with the driving force of wind-force or ocean current, when the revolving speed of input shaft 17 is higher, passes through pattern switching
It is mobile to 14 direction of output shaft castle wheel that mechanism makes sliding sleeve 15, so that the second end tooth 1401 is engaged with the first sliding sleeve end tooth 1501,
Output shaft 1 rotates together with the realization of input shaft 17 at this time, reaches straight and drives purpose, since output gear wheel 13 is empty set in output shaft
On 1, input pinion gear 16 be empty set on input shaft 17, therefore will not rotate, jackshaft 9 remains stationary；In addition, output
Axis 1 is when the inner ring 302 for driving freewheel clutch 3 rotates forward, due to the self-characteristic of freewheel clutch 3, when 302 revolving speed of inner ring is big
When outer ring 301, outer ring is will not to rotate, therefore ratchet 11 will not start to rotate.
Low speed accumulation of energy concentrates the principle of output as follows: input shaft 17 is rotated with the driving force of wind-force or ocean current, when defeated
Enter axis 17 revolving speed it is lower when, keep sliding sleeve 15 mobile to input 16 direction of pinion gear by pattern switching mechanism, so that first end
Tooth 1601 is engaged with the second sliding sleeve end tooth 1502, at this time input shaft 17 drive input pinion gear 16 rotate, and by jackshaft 9 with
And intermediate speed pinion 8 and gear broad in the middle 10 on 9, drive output gear wheel 13 to rotate, since output gear wheel 13 is empty set
On output shaft 1, therefore output shaft 1 will not rotate, and export in 13 rotation process of gear wheel, pawl 5 is in compression torsion spring 4
Under effect, the rotation of ratchet 11 is limited, therefore, 12 accumulation of energy of accumulation of energy torsional spring being mounted between output gear wheel 13 and ratchet 11,
And export the driving lever 7 on gear wheel 13 and turn to when being contacted with pawl arm 501, pawl 5 rotates around support frame 6 and takes pawl 5
The limitation to disappear to ratchet 11, in this case, accumulation of energy torsional spring 12 release energy, and ratchet 11 and freewheel clutch 3 is outer at this time
301 rotation of circle, due to the characteristic of freewheel clutch 3,301 forward rotational speed of outer ring is greater than inner ring 302, and inner ring 302 rotates with, from
And realize the rotation of output shaft 1, (the dotted line position in such as Fig. 6 when driving lever 7 is moved to the critical point with 501 contact position of pawl arm
Set), energy-storaging spring 12 discharges completely, and reversely rebound is pressed on limitation ratchet 11 on ratchet 11 to pawl 5 under the effect of compression torsion spring 4
Rotation, the outer ring 301 of freewheel clutch 3 are stopped rotating with ratchet 11, and 301 forward rotational speed of outer ring of freewheel clutch 3 is less than interior
Continue with inertia rotation output to stopping the disengaging of inner ring 302 outer ring 301 of circle 302, freewheel clutch.
The principle of pattern switching mechanism is as follows:
Photoelectric sensor 23 passes through what is reflected in induction twice reflecting pole 24 for incuding the photosignal reflected on reflecting pole 24
The angular speed of input shaft 17 can be calculated by single-chip microcontroller by 360 °/t by the interval time t of photosignal, and pass through
The magnitude of angular velocity of calculating determines that the height of input speed (presets decision content, is then high speed when higher than decision content, lower than decision content
Shi Zewei low speed), determined by high low speed, single-chip microcontroller controls the flexible of electric pushrod 19, to drive sliding sleeve 15 in input shaft
Horizontal direction on 17 is mobile；
In addition limit plate 21 is set in 20 lower end of shift fork of 19 end of electric pushrod, in limit plate 21 along the two of 17 axial direction of input shaft
Range sensor 22 is arranged in side, electronic with the signal control that range sensor 22 issues for limiting the range of sliding sleeve 15
The start and stop of push rod 19, to reach the protection purpose to sliding sleeve 15 and electric pushrod 19.
