The utility model solves the problems of the technologies described above adopted technical scheme: a kind of high-pressure vacuum breaker combined floodgate locking mechanism, comprise torsion spring, axle pallet, bearing pin and band pin bearing, described torsion spring is fixed on one end of combined floodgate axle, described combined floodgate axle is across on two pieces of adjacent dividing plates of circuit breaker assembling framework, described combined floodgate axle is fixed with combined floodgate axle connecting plate, described axle pallet is fixed on described combined floodgate axle, described axle pallet is near described torsion spring, the partial contour of described axle pallet contacts with described band pin bearing, described band pin bearing is arranged on assembly wheel, described assembly wheel is arranged on energy storage axle, the two ends of described energy storage axle are provided with energy-stored spring, in described assembly wheel, small pressure spring is installed, described energy storage axle is by motor driven, described bearing pin is eccentric pin shaft, one end of described eccentric pin shaft is provided with threaded portion, described threaded portion is provided with external screw thread, described eccentric pin shaft is arranged on the dividing plate of described torsion spring by a locking nut, one end of described torsion spring is buckled on the side end face away from described torsion spring of described axle pallet, the other end of described torsion spring is resisted against the surface of described eccentric pin shaft.
In assembling process, by unscrewing locking nut, available spanner rotates eccentric pin shaft, along with the rotation of eccentric pin shaft, axle pallet changes with the contact area of band pin bearing, thus the adjustment of switch-on latching amount size is achieved, when being adjusted to best snap close amount size, tighten locking nut again, eccentric pin shaft is fixed, namely complete the adjustment of switch-on latching amount.
Under the driving of motor, energy storage axle rotates, energy-stored spring is stretched put in place and storage power, now the partial contour of axle pallet contacts with band pin bearing, mechanism is in the lock state, ensureing that before closing a floodgate, the energy of energy-stored spring does not discharge, and guarantees that energy-stored spring is in extended state, carrying out energy reserve for closing a floodgate.After making electromagnet is charged, the push rod top pressing lock axle connecting plate on making electromagnet, combined floodgate axle rotates and is with moving axis pallet to rotate together, and after axle pallet departs from band pin bearing, assembly wheel rotates, and energy-stored spring resilience also releases energy, and combined floodgate completes.When making electromagnet push rod top not switching axle connecting plate time, switch-on latching amount can be regulated as required, realize the closing operation of high-pressure vacuum breaker under rated voltage or low-voltage, avoid the generation of the push rod top not switching axle connecting plate situation and the making electromagnet produced can not be threaded off smoothly because of making electromagnet.
As preferably, the other end of described eccentric pin shaft is provided with eccentric part, the center line of described eccentric part and the center line of described threaded portion be not on same straight line, integrally connecting portion is connected with between described eccentric part and described threaded portion, the surface of described connecting portion is made up of multiple plane, and the other end of described torsion spring is resisted against the surface of described connecting portion.Eccentric pin shaft is designed to the form of eccentric part that one connects, connecting portion and threaded portion, structure is simple, easy to process, is easy to the adjustment operation of switch-on latching amount.The surface of connecting portion is made up of multiple plane, is conducive to the contact area increasing connecting portion and torsion spring end, improves the reliability of mechanism.
As preferably, described axle pallet is fixed on described combined floodgate axle by an alignment pin, and described axle pallet, through described axle pallet and described combined floodgate axle, is fixed on described combined floodgate axle by described alignment pin.Axle pallet is connected by alignment pin with combined floodgate axle, easy to assembly, good connecting effect.
Compared with prior art, the utility model has the advantage of: disclosed in the utility model, high-pressure vacuum breaker combined floodgate locking mechanism comprises combined floodgate axle, torsion spring, axle pallet, bearing pin and band pin bearing, its bearing pin is eccentric pin shaft, one end of eccentric pin shaft is provided with threaded portion, threaded portion is provided with external screw thread, eccentric pin shaft is arranged on the dividing plate of torsion spring by a locking nut, one end of torsion spring be buckled in axle pallet away from the side end face of torsion spring, the other end of torsion spring is resisted against the surface of eccentric pin shaft.In assembling process, by unscrewing locking nut, available spanner rotates eccentric pin shaft, along with the rotation of eccentric pin shaft, axle pallet changes with the contact area of band pin bearing, thus the adjustment of switch-on latching amount size is achieved, when being adjusted to best snap close amount size, tighten locking nut again, eccentric pin shaft is fixed, the adjustment of switch-on latching amount can be completed.Because switch-on latching amount is adjustable, when making electromagnet push rod top not switching axle connecting plate time, switch-on latching amount can be regulated as required, realize the closing operation of high-pressure vacuum breaker under rated voltage or low-voltage, avoid push rod top not switching axle connecting plate and the adverse effect produced because of making electromagnet.
