Spring operating mechanism working method of the present invention:
Energy storage work: the initial condition of example medi-spring operating mechanism of the present invention as shown in Figure 1, when operating mechanism needs energy storage, electrical power utilizes reduction gearing to drive bent axle 18 and rotates, bent axle 18 drives inside and outside energy storage ratchet 19 and alternately promotes two ratchets on ratchet 7 circumference, ratchet 7 is rotated counterclockwise, ratchet 7 drivening rods 31 move upward, connecting rod 31 drives guide roller 36, joint 37, screw rod 39 and supporting plate 40 and moves upward together, supporting plate 40 moves upward and just compresses switching-in spring 32, and switching-in spring 32 elastic potential energys are stored.
Combined floodgate energy storage locking: the energy storage lock-out state of example medi-spring operating mechanism of the present invention as shown in Figure 2, when connecting rod 31 and ratchet 7 rotated the dead point, the sincere sub-connecting lever 3 that closes a floodgate reduction torsion spring 6 effect of being closed a floodgate, combined floodgate roller 5 is entered in the locking draw-in groove of ratchet 7, semiaxis A3 is backed down on sincere sub-connecting lever 3 tops of closing a floodgate simultaneously, semiaxis A3 is closed a floodgate sincere sub-connecting lever 3 when backing down, and semiaxis A3 drives to close a floodgate and sincere sub 2 rotates, and sincere sub 2 compression combined floodgate back-moving springs 44 close a floodgate; Close a floodgate after sincere sub-connecting lever 3 tops break away from semiaxis A3, sincere sub 2 back-moving spring 44 active forces that closed a floodgate that close a floodgate restPose and drive semiaxis A3 and rotate, semiaxis A3 blocks the sincere sub-connecting lever 3 that closes a floodgate, the combined floodgate roller 5 that closes a floodgate on the sincere sub-connecting lever 3 is stuck in the locking draw-in groove of ratchet 7, with ratchet 7 lockings, this moment, the potential energy of switching-in spring 32 was locked, and the energy storage action is finished.
When connecting rod 31 moved to peak, connecting rod 31 positions were the dead point.
Closing operation: when making electromagnet 4 energising, the push rod of making electromagnet 4 promotes sincere sub 2 the locking bar that closes a floodgate, the sincere sub 2 compression combined floodgate back-moving springs 44 and drive semiaxis A3 and rotate of closing a floodgate, and semiaxis A3 breaks away from the top of the sincere sub-connecting lever 3 that closes a floodgate; Ratchet 7 positions are no longer by 5 lockings of combined floodgate roller, because the active force of switching-in spring 32 is greater than the active force of combined floodgate reduction torsion spring 6, close a floodgate sincere sub-connecting lever 3 and combined floodgate roller 5 pushed away the draw-in groove of ratchet 7, the elastic force potential energy of switching-in spring 32 is released, promote supporting plate 40 downward rapid movements, supporting plate 40 drives screw rod 39, joint 37, guide roller 36, connecting rod 31, cam 9 moves downward together, ratchet 7 rotates counterclockwise fast, sincere sub 2 effects of being closed a floodgate back-moving spring 44 of closing a floodgate, return to the preceding state of energy storage, close a floodgate sincere sub-connecting lever 3 and combined floodgate roller 5 also return to the preceding state of energy storage; When ratchet 7 and cam 9 rotate together, the drive balls A5 of cam 9 bump locating detents 10 and little connecting lever 21, promoting locating detent 10, little connecting lever 21 and bridge shape connecting plate 43 moves downward, bridge shape connecting plate 43 promotes spring base 14 and moves downward, and drive transmission crank arm 12 rotations, and transmission crank arm 12 drives output shafts 11 and rotates, and output shaft 11 drives output toggle arms 8 and rotates, output toggle arm 8 drives breaker closing, carries out closing operation.
Closing position locking (separating brake energy storage locking): combined floodgate locking (separating brake energy storage locking) state of example medi-spring operating mechanism of the present invention as shown in Figure 3, when ratchet 7 drives the counterclockwise quick rotation of cam 9, the drive balls A5 of cam 9 bump locating detents 10 and little connecting lever 21, promote locating detent 10, little connecting lever 21, bridge shape connecting plate 43 and spring base 14 move downward, spring base 14 compresses tripping springs simultaneously, when locating detent 10 is pulled to sincere sub-connecting lever 25 1 ends of separating brake, after both clash into contact, roller 24 before the separating brake on the sincere sub-connecting lever 25 of hook groove locking separating brake on the locating detent 10, the sincere sub-B28 of separating brake withstands roller 29 behind the separating brake on the sincere sub-connecting lever 25 of separating brake, carry out spacing to the sincere sub-connecting lever 25 of separating brake, thereby spacing locating detent 10, bridge shape connecting plate 43, spring base 14 and transmission crank arm 12, transmission crank arm 12 locking output shaft 11 and output toggle arms 10, thereby closing position is locked, tripping spring 33 is compressed simultaneously, and the elastic potential energy of tripping spring 33 is stored.
Sub-switching operation: state behind the separating brake of example medi-spring operating mechanism of the present invention as shown in Figure 4, after tripping electromagnet 23 energisings, tripping electromagnet 23 push rods promote the sincere sub-A27 of separating brake and rotate, sincere sub-A27 of separating brake and the coaxial locking of the sincere sub-B28 of separating brake are rotated together, roller 29 behind the sincere sub-B28 disengaging separating brake of separating brake, make the sincere sub-connecting lever 25 of separating brake lose spacing restriction, tripping spring 33 potential energy are released, locating detent 10 is driven by the potential energy of tripping spring 33 with the preceding roller 24 of the separating brake on the sincere sub-connecting lever 25 of separating brake and breaks away from, tripping spring 33 promotes spring base 14 and moves upward, spring base 14 drives transmission crank arm 12 and rotates, transmission crank arm 12 drives output shaft 11 and output toggle arm 8 rotates, output toggle arm 8 drives breaker open operation, finishes sub-switching operation; After sub-switching operation was finished, transmission crank arm 12, spring base 14, bridge shape connecting plate 43, locating detent 10, the sincere sub-A27 of separating brake and the sincere sub-B28 of separating brake returned to the state before the separating brake energy storage.
