As shown in Figure 8 a, switch is set in double quartiles and operating mechanism 2 is in 22 combined floodgate ready position of the first spring mechanism When: the upper connecting rod 221 in first spring mechanism 22 is under the action of 224 spring force of energy-stored spring, the upper company of upper connecting rod 221 Bar limitation locking face 22114 and the lock face 282221 on the lock 2822 in the first snap close piece 282 are inconsistent, make lock 2822 The trend rotated counterclockwise around its centre of gyration is kept after overcoming own spring force, due to the hasp limit of 2822 other ends of lock Face 282211 leans with the lock confined planes 282142 on hasp 2821, so that lock 2822 is remain stationary, due to lock The centre of gyration of hasp 2821 is passed through in the direction of the active force of 2822 pairs of hasps 2821, therefore hasp 2821 is in own spring force It is remained stationary under the action of rack 21, the upper connecting rod 221 of the first spring mechanism 22 is made to be locked in upper connecting rod upper limit boss At 2114.Pulling force effect of the free end of the upper connecting rod 221 of the second spring mechanism 22 ' by energy-stored spring 224, around return Turn center to be lifted up, and is resisted against on upper connecting rod upper limit boss 2114.At this time due to the lower company in the first spring mechanism 22 Lower link 222 in bar 222 and second spring mechanism 22 ' makes output shaft 23 all in the upper end of the sliding slot 2321 of output shaft 23 It is maintained at by-level position, is rested on the second contact position by the contact mechanism that output shaft 23 drives, double points for realizing switch Position.The on/off switch lever in on/off switch lever 223 and the second spring mechanism 22 ' in first spring mechanism 22 223 are connected by connecting rod 24, form a parallelogram sturcutre.After the first drive electromagnet is powered, the first driving electromagnetism The dynamic iron core 251 of iron 25, static iron core 252 are attracted, after the first drive electromagnet power loss, under the active force of reset spring 255, Dynamic iron core is moved to the direction far from static iron core, and still, energy-stored spring 224 is to the first coiling machine in first spring mechanism 22 What the on/off switch lever 223 in structure 22 generated rotates clockwise torque less than energy-stored spring 224 in the second spring mechanism 22 ' Torque, the on/off switch thick stick of the first spring mechanism 22 are rotated counterclockwise to what the on/off switch lever 223 of second spring mechanism 22 ' generated Bar 223 is resisted against on on/off switch lever positive stop lug boss 2117, and is had to the dynamic iron core 251 of the first drive electromagnet 25 downward The pressure of (state position Fig. 8 a), so that the dynamic iron core 251 of the first drive electromagnet 25 is located below position, and at this point, second The dynamic and static iron core 251,252 of drive electromagnet 25 ' is located at separation point position, and the dynamic iron core 252 of the second drive electromagnet 25 ' is located at Top position.Each movable part of operating mechanism 2 can be stably held in the location status.

Under said mechanism state, close a floodgate if you need to carry out the first spring mechanism 22, then its action process principle is as follows: to lock The trigger electromagnet 284 of buckle device 28 is powered and the sound iron core of trigger electromagnet is attracted, and push rod 2846 is driven to push electronic solution Button bar 282130 or by pressing the first snap close piece 282 in hasp 2821 trip rod 28212, then left side hasp bar 28213 It rotates counterclockwise, after the hasp confined planes 282211 on lock 2822 lose the limitation of hasp 2821, the first spring mechanism 22 Upper connecting rod 221 free end can energy-stored spring 224 release can pulling force effect under, push lock face 282221 open, make to latch 2822 rotate counterclockwise around hinge joint, and upper connecting rod 221 is unlocked and rotated clockwise around hinge joint, and drives lower link 222 One end be moved to the other end from one end of the sliding slot 2321 of output shaft 23, to drive lower link 222 and output shaft 23 together It rotates by a certain angle counterclockwise.Finally, the free end of the upper connecting rod 221 of the first spring mechanism 22 abuts to upper connecting rod lower limit axis On 2121, so that the hinge joint between upper connecting rod 221 and lower link 222 is passed through dead-centre position, (upper connecting rod 221 and lower link 222 are big Cause to be in 180 °) rigidity supporting structure is formed, drive output shaft 23 to rotate counterclockwise, so that contact mechanism be driven to act.It crosses herein Cheng Zhong after the lock 2822 unlocks, under own spring force effect, generates the power rotated clockwise, locking-bar 28222 Limit end face 282222 be resisted against on the sliding confined planes 22113 of upper connecting rod 221.Under in the second spring mechanism 22 ' Connecting rod 222 is due to providing certain freedom degree between output shaft 23, when 22 side of the first spring mechanism being made to close a floodgate, the second bullet Lower link 222 in spring mechanism 22 ' can accordingly slide in the sliding slot 2321 of output shaft 23, make the conjunction of second spring mechanism 22 ' Separating brake lever 223 and upper connecting rod 221 remain stationary, meanwhile, each connecting rod in second spring mechanism 22 ' is in energy-stored spring 224 It is held in place and sets under effect, such as Fig. 8 b.Preferably, the folder on the position shown in 8b between output arm 232 and lower link 222 Angle (towards the angle to drive electromagnet 25) is 75 °~80 °, so that one to the reaction force of lower link 222 of contact mechanism By the center of rotation of output shaft 23, (power makes the output shaft pin shaft 226 on lower link 222 be maintained at leaning on for sliding slot 2321 to component One end of nearly output shaft center of rotation), another component is by upper connecting rod 221, the articulated shaft of lower link 222.Reach first When contact closing position, the lower link limit shaft 2122 of 22 side of the first spring mechanism acts on corresponding lower link 222 Lower link transverse slat 2222, the limit of output shaft pin shaft 226 on lower link 222 is rotated in the close output shaft 23 of sliding slot 2321 The one end at center, to ensure that the contact pressure of dynamic/static contact when the first contact position, specific structure such as Figure 10 a makes to operate Mechanism will not cause lower link to slide because of reasons such as closing rebound, contact abrasions and eventually lead to contact over travel, pressure reduces. After the pressing force in 284 power loss of locker trigger electromagnet or trip rod 28212 is cancelled, the hasp 2821 in left side is at itself It is resetted under the action of spring, the bottom surface of positive stop lug boss 28214 is resisted against on limit end face 2822111, ensure that its is subsequent The correctness of separating brake movement.In the process, for the upper connecting rod 221 of second spring mechanism 22 ' energy-stored spring 224 pulling force With the same position that the ready moment of closing a floodgate with the first spring mechanism is maintained under the action of upper connecting rod upper limit boss 2114, thus The lock 2822 of second snap close piece 282 ' is remained stationary, therefore, even if trigger electromagnet 284 is powered or the second lock of pressing The trip rod 28212 of part 282 ', the lock 2822 of the second snap close piece 282 ' are still protected with the upper connecting rod 221 of second spring mechanism 22 ' Lock state is held, the second snap close piece 282 ' is held in place.Under the first spring mechanism "on" position, due to the first driving electromagnetism 25 energized action of iron, after sound iron core is attracted, after 25 cutoff action power supply of the first drive electromagnet, in reset spring 255 Under active force, dynamic iron core 251 is moved to far from the direction of static iron core 252, still, such as Fig. 8 b, in the storage of the first spring mechanism 22 Under the pulling force effect of energy spring 224, the on/off switch lever 223 of the first spring mechanism 22 is resisted against on/off switch lever positive stop lug boss On 2117, the upper connecting rod 221 of the first spring mechanism 22 is resisted against on upper connecting rod lower limit axis 2121, and to the first drive electromagnet 25 dynamic iron core 251 has the pressure of downward (state position Fig. 8 b), so that the dynamic iron core of the first drive electromagnet 25 251 It is remained stationary in the on/off switch lever 223 of lower position, second spring mechanism 22 ' by the effect of connecting rod 24, in second spring Under 224 pulling force effect of energy-stored spring of mechanism 22 ', it is convex that the upper connecting rod 221 of second spring mechanism 22 ' is resisted against upper connecting rod upper limit On platform 2114, the dynamic iron core 251 of the second drive electromagnet 25 ', static iron core 252 are located at separation point position, the second drive electromagnet 25 ' Dynamic iron core 252 be located above position, whole operation 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 storage bullet in second spring mechanism 22 ' Spring 224 starts combined floodgate energy storage, and the energy-stored spring 224 in the first spring mechanism 22 starts separating brake energy storage, when the first spring mechanism 22 In 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 first spring mechanism 22 abuts on upper connecting rod upper limit boss 2114, completes separating brake.At this point, Lock 2822 rotates clockwise under the action of own spring force, connects from the slide-in of the sliding confined planes 22113 of upper connecting rod 211 On the upper connecting rod limitation locking face 22114 of bar 221,2822 limit end face 2822111 is latched from the bottom of positive stop lug boss 28214 It is sliped off on face, releases the restriction to hasp bar 28213, rotate clockwise hasp 2821 under own spring force effect, until Its electronic 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, The energy-stored spring 224 of second spring mechanism 22 ' just across dead-centre position, reaches combined floodgate ready position, such as Fig. 8 d, second spring Upper connecting rod 221 in mechanism 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 It is inconsistent with the lock face 282221 on the lock 2822 in the second snap close piece 282 ', after so that lock 2822 is overcome own spring force The trend rotated clockwise around the centre of gyration is kept, but due to the lock on 2822 other end confined planes of lock and hasp 2821 Confined planes 282142 lean, and the centre of gyration of hasp 2821 is passed through in the direction of the power, therefore hasp 2821 is in itself spring It is remained stationary under the action of power, locks the upper connecting rod 221 of second spring mechanism 22 ' at upper connecting rod upper limit boss 2114, it is complete At 22 ' the combined floodgate energy storage of second spring mechanism.At this time due to the lower link 222 and second spring mechanism in the first spring mechanism 22 Lower link 222 in 22 ' makes output shaft 23 be maintained at by-level position, realizes machine all in the upper end of 23 sliding slot of output shaft Double quartiles of structure are set, at this point, operating mechanism 2 is located at 22 ' combined floodgate ready position of second spring mechanism, corresponding second spring mechanism The on/off switch lever positive stop lug boss 2117 of 22 ' sides limits the on/off switch lever 223 of second spring mechanism 22 ', while right The upper connecting rod upper limit boss 2114 of 22 side of the first spring mechanism is answered to limit the upper connecting rod 221 of the first spring mechanism 22. While second drive electromagnet 25 ' pulls down the on/off switch lever 223 of second spring mechanism 22 ', the conjunction of the first spring mechanism 22 Separating brake lever 223 pulls the dynamic iron core 251 of the first drive electromagnet 25 to move upwards by electromagnet connecting rod 258.In such as Fig. 8 b To Fig. 8 d the first spring mechanism 22 from closing a floodgate to during separating brake, due to the lower link limit shaft of 22 side of the first spring mechanism 2122 act on the lower link transverse slat 2222 of corresponding lower link 222, and the limit of output shaft pin shaft 226 on lower link 222 is existed One end of 23 center of rotation of close output shaft of sliding slot 2321, so that lower link is during switching separating brake, lower link and output The hinged output shaft pin shaft of axis is constantly on the inside of output shaft sliding slot, until separating brake just skids off on the inside of sliding slot after in place, so that Contact opening velocity is faster.

Under said mechanism state, such as so that second source is closed a floodgate, then carry out the combined floodgate of second spring mechanism 22 ', reach such as The position Fig. 8 e, operating mechanism 2 is located at 22 ' closing position of second spring mechanism at this time, corresponds to the upper of 22 ' side of second spring mechanism Connecting rod lower limit axis 2121 limits the upper connecting rod 221 of second spring mechanism 22 ', while corresponding first spring mechanism, 22 side Upper connecting rod upper limit boss 2114 upper connecting rod 221 of first spring mechanism 22 is limited.Its operating principle process and the One spring, 22 combined floodgate principle is consistent.When reaching the second contact closing position, the lower link of the 22 ' side of second spring mechanism Limit shaft 2122 acts on the lower link transverse slat 2222 of corresponding lower link 222, by the output shaft pin shaft 226 on lower link 222 It limits in one end of 23 center of rotation of close output shaft of sliding slot 2321, to ensure that dynamic/static contact when the second contact position Contact pressure, specific structure such as Figure 10 b.

The operating mechanism 2 of the utility model includes the first spring mechanism 22 and second spring mechanism 22 ', the utility model institute The locating part stated includes: the lower link transverse slat 2222 of corresponding first spring mechanism 22, in rack 21 in the first contact-closed position One lower link limit shaft 2122 of upper setting, and, in the second contact-closed position, the lower company of corresponding second spring mechanism 22 ' Bar transverse slat 2222, another lower link limit shaft 2122 being arranged in rack 21, such as Figure 10 a, 10b, in the first contact closure position When setting, the lower link limit shaft 2122 in left side and 2222 mating reaction of lower link transverse slat in left side, in the second contact-closed position When, 2222 mating reaction of lower link transverse slat of the lower link limit shaft 2122 on right side and right side.

Certainly, locating part described in the utility model is not limited to the form of above-mentioned lower link limit shaft 2122, can also be in machine Groove is arranged in corresponding position on frame 21, carries out to the output shaft pin shaft 226 of the first spring mechanism 22 and second spring mechanism 22 ' It lengthens, i.e., it is its is axially extending, cooperate respectively with corresponding groove in the first contact-closed position and the second contact-closed position, Output shaft pin shaft 226 is limited to the end of 23 center of rotation of close output shaft of sliding slot 2321, equally ensure that contact closure Contact pressure when position, between dynamic/static contact.
