Separating brake energy-stored spring is connected with separating brake rotating shaft 12, and combined floodgate energy-stored spring is connected with combined floodgate rotating shaft 13.Energy storage
Axle 141 can rotate under the drive of rocking bar, so that each energy-stored spring carries out energy storage.As a example by closing a floodgate: close
Before lock, hand rocking bar makes energy storage axle 141 rotate, and now combined floodgate energy-stored spring 142 starts energy storage, energy storage
After completing, before combined floodgate, the cam in chopper on/off switch module stops combined floodgate energy-stored spring 142 to discharge
Energy.
Referring to the drawings 1, below in conjunction with concrete operation principle, this spring operating mechanism is carried out furtherly
Bright:
1), during chopper on/off switch module closing operation: manual operation rocking bar, make energy storage axle 141 clockwise
Rotating, put in place to combined floodgate energy-stored spring 142 stretching being connected with energy storage axle 141, i.e. close a floodgate energy-stored spring
142 start energy storage, after energy storage completes, and before closing a floodgate, and the cam in chopper on/off switch module
Parts (not shown) stops combined floodgate energy-stored spring 142 to rotate, i.e. locating part on cam withstands conjunction
Lock energy-stored spring 142 so that it is cannot rotate, i.e. stops it to release energy, and then holds combined floodgate pivoted arm 131,
Making combined floodgate rotating shaft 13 rotate, breaker closing, during combined floodgate, combined floodgate energy-stored spring 142 releases energy, for closing
Lock provides driving force.Simultaneously as divide-shut brake main shaft 11 links with combined floodgate rotating shaft 13, divide-shut brake main shaft
11 rotate under the drive of combined floodgate rotating shaft 13, thus drive on/off switch indicator board 15 to rotate counterclockwise 40
°, and make connecting rod 31 drive ground connection rotating shaft baffle plate 32 to turn clockwise, make ground connection rotating shaft baffle plate 32 block
Living ground connection rotating shaft 21, to stop ground connection rotating shaft 21 to rotate, feed motion completes, on/off switch indicator board 15
Upper display " is closed ", and now earthed switch module is in gate-dividing state.
2), during chopper on/off switch module sub-switching operation: while above-mentioned combined floodgate, separating brake energy-stored spring is carried out
Energy storage, to guarantee energy tripping switch closes when.Hold separating brake pivoted arm 121, make separating brake rotating shaft 12
Rotate to an angle, make breaker open operation.Meanwhile, when separating brake rotating shaft 12 rotates, drive divide-shut brake main shaft
11 turn to open position, thus drive on/off switch indicator board 15 to turn clockwise 40 °, make connecting rod 32
Driving ground connection rotating shaft baffle plate 32 to turn clockwise, now interlock plate 331 staggers with bent plate 132, and ground connection is opened
Close module and be in operable state.
3) earthed switch module closing operation: chopper, under gate-dividing state, rotates ground connection rotating shaft counterclockwise
21, half-twist, earthed switch has closed a floodgate.In order to prevent power equipment short circuit, earthed switch is in
During "on" position, chopper can not be in "on" position, therefore, drives interlocking when ground connection rotating shaft 21 rotates
Plate 331 rotates, so that stop screw is by stuck for bent plate 132, i.e. the gib head of bent plate 132 is hung on spacing
With the nail of screw, make combined floodgate rotating shaft 13 to operate, thus reach interlock requirement, say, that this
Time chopper can not work, only earthed switch can work.
4) earthed switch module sub-switching operation: turn clockwise ground connection rotating shaft 21, half-twist, ground connection
Switch separating brake completes.Now, what interlock plate 331 was positioned on the lower section of bent plate, i.e. interlock plate 331 is spacing
The gib head of screw and bent plate 132 is avoided, and combined floodgate rotating shaft 13 can operate, say, that now earthed switch
Being in gate-dividing state, chopper can close a floodgate.
