Discrete state, operating shaft are in free state, at this point, the open position for the position corresponding load switch that operating shaft is stopped or
Closing position；In the present embodiment, when first positioning bolt is reached close at the position of the switch, on-load switch is in sub-gate position
It puts, when second positioning bolt is reached close at the position of the switch, on-load switch is in closing position.Operation handle 7, which has, to be referred to
Needle construction 71 is provided with " combined floodgate " mark and " separating brake " mark on 1 side wall of mechanism case, and being directed toward " combined floodgates " when pointer structure 71 indicates
When, corresponding load switch is in "on" position, and when pointer structure is directed toward " separating brake " mark, on-load switch is in gate-dividing state.
When on-load switch is in sub-gate position or closing position, clutch is in discrete state, between electric operating and manual operation
It does not influence mutually, can both start detecting system and driving motor action is caused to realize switch divide-shut brake, it can also be by revolving manually
Turn operation handle and realize switch divide-shut brake.
Since floating disc 12 and yoke frame 13 are coordinated by boss and raised pushing tow, realize that floating disc divides with fixed disk 14
From, in this way, when clutch is in discrete state, it is floating only after driving wheel 11 drives floating disc 12 first to turn an angle
Moving plate 12 can just realize transmission cooperation with fixed disk 14, and clutch can just realize engagement, that is to say, that start to rotate in driving wheel
When, only driving wheel 11 first turns an angle so that the boss on floating disc is staggered after the protrusion on yoke frame 13, floats
Disk 12 can drive operating shaft to rotate after being clamped with fixed disk 14, and therefore, the rotation of operating shaft 8 can lag behind driving wheel 11.It is main
It is symmetrical arranged on driving wheel 11 there are two positioning bolt 21, after driving wheel 11 drives floating disc 12 to rotate 180 °, detecting system is just
Driving motor 3 can be controlled to be stopped, when driving wheel 11 drives floating disc to rotate 180 °, since operating shaft rotational hysteresis is in master
Driving wheel, the rotational angle of operating shaft 8 is less than 180 °, for on-load switch, from open position to closing position or from point
Gate position is to closing position, it is only necessary to which operating shaft rotates 90 ° and switching on and off action can be completed, this is just determined from open position
To closing position or from open position to closing position, operating shaft 8 must be rested on apart from the position of the upper 90 ° of corners in a position
Place.Therefore, in the present embodiment, uniform intervals are provided with four pairs of conductive contact blades 19 in inductive disks, that is to say, that from open position
To closing position or from open position to closing position, the contact 9 in operating shaft 8 often rotates 90 ° and will be touched with corresponding conduction
The conductive cooperation of piece 19, while controller control motor stalls, and on-load switch is caused to be maintained at open position or combined floodgate
Position when needing to be again started up, needs to restart driving motor.In the present embodiment, conductive contact blade 19 is along inductive disks
The arc-shaped flaky structure of circumferentially extending in this way when contact and conductive contact blade coordinate, can allow for contact to have in the circumferential centainly
Fault-tolerant surplus, and then improve the fit precision of conductive contact blade and contact.Operating mechanism in the present invention is sealed-box type structure,
It can achieve the effect that moisture-proof, dust-proof, adapt to severe working environment.
The operation principle of operating mechanism of the present invention：In use, the operating shaft of the motor-operating mechanism and moving for on-load switch
Structure of contact terminal is sequentially connected, and then drives on-load switch divide-shut brake.Open position is in on-load switch（Or closing position）When,
Driving motor is in stop state, and the boss on floating disc 12 be in pushing tow mated condition with the protrusion on yoke frame 13, floating
Disk 12 is in disengaged position with fixed disk 14, and operating shaft 8 can both be manually operated at this time and realized that on-load switch closes a floodgate, can also open
The dynamic electronic 3 actuating on-load switch of driving closes a floodgate.When need carry out closing operation（Or sub-switching operation）When, controller control driving electricity
Machine 3 rotates, and driving wheel 11 drives floating disc 12 to rotate, and the boss on floating disc 12 is staggered with the protrusion on yoke frame 13, in bullet
Under the elastic force effect of spring 16, floating disc 12 is automatically close to fixed disk 14 so that and floating disc 12 coordinates with the fixed transmission of disk 14, and then
Fixed disk and operating shaft 8 is driven to rotate.Driving wheel 11 drives floating disc to rotate 180 °, boss and yoke frame 13 on floating disc 12
On protrusion pushing tow coordinates again, floating disc 12 is detached from fixed disk 14, while senses positioning bolt 21 close to switching 4
It puts, controller control driving motor 3 stalls, and on-load switch realizes closing operation.
In other embodiments of the invention, driving wheel and motor output gear may be replaced by sprocket wheel or other transmissions
Structure.
In other embodiments of the invention, it can also be coordinated between the floating disc of clutch and fixed disk by CONTACT WITH FRICTION
Mode realize drive connection.
In other embodiments of the invention, can according to needed for operating shaft during on-load switch divide-shut brake rotational angle size come
The logarithm of separating brake conductive contact blade pair and combined floodgate conductive contact blade pair is set, e.g., when rotational angle needed for operating shaft is 180 degree, separating brake,
Combined floodgate conductive contact blade can only set a pair.
In the present invention, movable part is engaged with fixed part and realizes signal, in other embodiments, movable part
Signal can not be realized with fixed part by being engaged by dividing, as passed through infrared ray between movable part and fixed part
Remote sensing.
In other embodiments of the invention, conductive contact blade can be single chip architecture, and contact and conductive contact blade are all connected at this time
There is conducting wire, fracture texture is formed between contact and contact, when contact and the cooperation of contact conductive contact, circuit is switched on.
In other embodiments of the invention, positioning bolt can also be arranged to be uniformly distributed circumferentially four.
In other embodiments of the invention, can also pillar be set on one in floating disc and fixed disk, another
On be correspondingly arranged the hole being inserted into for boss.
