A operating mechanism 2 is maintained at the first spring mechanism "on" position.
Under said mechanism state, when the second drive electromagnet 25 ' is powered, the dynamic iron core of the second drive electromagnet 25 '
251 move downward, and the dynamic iron core 251 of the second drive electromagnet 25 ' drives second spring mechanism 22 ' by electromagnet connecting rod 258
In on/off switch lever 223 rotate clockwise, due to the on/off switch lever 223 and second spring mechanism of the first spring mechanism 22
22 ' on/off switch lever 223 forms parallel four by connecting rod 24 and connects shape structure, therefore the on/off switch lever of the first spring mechanism 22
223 rotate clockwise with the on/off switch lever 223 of second spring mechanism 22 '.Energy-stored spring in second spring mechanism 22 '
224 start combined floodgate energy storage, and the energy-stored spring 224 in the first spring mechanism 22 starts separating brake energy storage, when in the first spring mechanism 22
Energy-stored spring 224 across dead-centre position, (224 both ends of energy-stored spring and 221 centre of gyration of upper connecting rod are on same straight line
When), such as Fig. 8 c.The free end of the upper connecting rod 221 of first spring mechanism 22 can energy-stored spring 224 release can pulling force effect under,
It is rotated counterclockwise around hinge joint, and one end of lower link 222 is driven to slide into the other end from one end of output shaft 23, thus band
Dynamic lower link 222 and output shaft 23 rotate clockwise certain angle, the locking-bar of the lock 2822 in the first snap close piece 282 together
28222 limit end face 282222 can be slided all along the sliding confined planes 22113 on 221 excircle of upper connecting rod.Finally,
The free end of the upper connecting rod 221 of one spring mechanism 22 abuts on upper connecting rod upper limit boss 2114, completes separating brake.At this point, lock
Button 2822 rotates clockwise under the action of own spring force, slides into upper connecting rod from the sliding confined planes 22113 of upper connecting rod 211
On 221 upper connecting rod limitation locking face 22114,2822 limit end face 2822111 is latched from the bottom surface of positive stop lug boss 28214
It slips off, releases the restriction to hasp bar 28213, rotate clockwise hasp 2821 under own spring force effect, until its electricity
Dynamic trip rod 282130 is resisted against on fixed plate transverse slat 2812, to realize that the first snap close piece 282 automatically resets.At this point, second
The energy-stored spring 224 of spring mechanism 22 ' just across dead-centre position, reaches combined floodgate ready position, such as Fig. 8 d, second spring mechanism
Upper connecting rod 221 in 22 ' is under the action of 224 power of energy-stored spring, the upper connecting rod limitation locking face 22114 of upper connecting rod 221 and
The lock face 282221 on lock 2822 in two snap close pieces 282 ' is inconsistent, keeps after so that lock 2822 is overcome own spring force
