The centre bore of wheel is connected with the output shaft of motor, and the motor is fixedly connected on fixed seat, and the fixed seat both sides are protruding
There are symmetrically arranged holder one, one or two of symmetrical end of holder to be symmetrically arranged with swing rod, the swing rod centered on fixed seat
L-shaped, one side of swing rod is vertically arranged, and the another side of swing rod is laterally arranged, the intersection on two sides of the swing rod be provided with
The torsional spring one of the end connection of holder one, the torsional spring one are used for that swing rod is made to reset, the vertical side of two symmetrically arranged swing rods
Upper end be provided with armature contact, fixed contact connect with external circuit is correspondingly arranged on above two armature contacts, two is movable
It is electrically connected between contact, the traveller is symmetrically extended with holder two, two outside of the holder centered on fixed seat towards both sides
End symmetric be provided with directive wheel, the directive wheel is set to the upside on the side that swing rod is laterally arranged, and same flat with swing rod
Face is arranged, and the fixed seat is symmetrically arranged with holder three, the end of the holder three centered on two upside of holder is by fixed seat
It is provided with card slot, the both sides of U type holders are symmetrically slidably connected in the card slot of the holder three, one side of the u-bracket
Upper end is hinged with fixed rotation by torsional spring and threads off, and the another side of the u-bracket is provided with mobile rotation and threads off, described solid
Fixed rotation is threaded off and mobile rotation is threaded off and electrically connected, and one end that the mobile rotation is threaded off is rotatably connected to connecting shaft, the company
Spindle is slidably connected with the lateral sliding slot that u-bracket is arranged, and when fixed contact and armature contact fitting, connecting shaft is located at
The end of sliding slot is simultaneously contacted with the side wall of sliding slot, and the other end of the sliding slot is located at fixed rotation dropout side, the mobile rotation
The other end for turning to thread off is provided with protrusion, the raised groove clamping being correspondingly arranged of threading off with fixed rotation, the mobile rotation
Turn dropout upper surface and be provided with thermal sensation bi-metal leaf spring, the lower surface that the mobile rotation is threaded off is connected with circular column draft bullet
One end of spring one, the circular column draft spring one are connect with the holder four stretched out on the outside of fixed seat, and the holder four is set to
The downside that mobile rotation is threaded off, the end set of the holder four are useful for limiting the block of mobile rotation dropout rotation angle,
The upper end of the traveller is hinged with one end of driving lever by torsional spring, the other end of the driving lever stretch out in the outside of traveller and with
The lower face that fixed rotation is threaded off is resisted, thumb wheel, drive lower edge heat of the thumb wheel in traveller are hinged in the middle part of the driving lever
The upper surface for feeling bi-metal leaf spring rolls movement, and the end on the u-bracket both sides is also symmetrically arranged with U-type groove, the U
Circular column draft spring two is connected in type groove, the drift of the circular column draft spring two is less than the groove depth of U-type groove, described
Two other end of circular column draft spring along the traveller direction of motion be arranged and connect with fixed seat upper end, the slot bottom of the u-bracket and
Holder two is connected by circular column draft spring three, and when armature contact and fixed contact contact, circular column draft spring three is in certainly
By length.When opening a sluice gate, open motor, control motor band carry-over bar is moved downward, is moved downward to traveller, motor not
Circular column draft spring three when movement is in drift, and pulling force is zero at this time, and the drift of circular column draft spring two is small
In the groove depth of U-type groove, U-type groove is bonded under the pulling of circular column draft spring two with the upper end of fixed seat, is moved downward in traveller
In the process, holder two generates pulling force by circular column draft spring three to u-bracket, in the pulling force that circular column draft spring three generates
When less than circular column draft spring two to overcome length difference generates between U-type groove depth pulling force, u-bracket is motionless, therefore solid

Bar is also rotated centered on thumb wheel simultaneously, and driving lever one end provokes fixed rotation and threads off upwards, and protrusion is separated with groove, mobile rotation
Turn to thread off under the pulling of circular column draft spring one, to rotate centered on connecting shaft, stop motion at block to be moved to, in movement
Rotation is threaded off and fixed rotation is threaded off after disengaging, and traveller continues to move downward, when circular column draft spring three generates enough pulling force
When, u-bracket moves downward, and threads off centered on connecting shaft against circular column draft with the mobile rotation for connecting axis connection at this time
The direction of pull of spring one rotates, and when rotation is clamped to protrusion with groove again, mobile rotation is threaded off and fixed rotation is threaded off
In conjunction with the reset that the mobile rotation of completion is threaded off；During draw runner moves downward, when the directive wheel on holder two rolls crimping
When guide groove on swing rod, the side of swing rod being laterally arranged under the pressure of directive wheel to be rotated centered on torsional spring one, activity
Contact rotates simultaneously under the drive on the vertically arranged side of swing rod, turns to outside and the fixed contact dislocation point of fixed contact
It leaves, realizes the function of opening a sluice gate, and when isolation cover turns to and surrounds fixed contact, further realize fixed contact and work
The isolation of movable contact further reduced the probability of electric arc generation；
When closing a floodgate, motor driving traveller moves upwards, and u-bracket and mechanism connected to it are in circular column draft spring
Be raised above under two pulling force, and stop rising when U-lag upper end and fixed seat contact, concurrently, due to directive wheel to
Upper movement, swing rod are swung under the action of the reset force of torsional spring one, and isolation cover is detached from fixed contact, and armature contact is in swing rod
It turns under drive and is bonded with fixed contact, realize closing function.
When overload, when electric current is more than rated current, the thermal sensation bi-metal leaf spring that mobile rotation is threaded off occurs upward
Bending, the thumb wheel for being crimped on thermal sensation bi-metal leaf spring upper surface move upwards, to drive the driving lever being connect with thumb wheel upward
Fixed rotation is threaded off and is provoked upwards by movement, driving lever, the groove point threaded off with fixed rotation to the protrusion that mobile rotation is threaded off
It opens, mobile rotation is threaded off under the pulling force of circular column draft spring one to rotate centered on connecting shaft and stop under the limit of block
It only moves, completes the tripping of overload.
The present invention realizes the folding of armature contact and fixed contact by controlling the up and down motion of motor control traveller,
It is easy to operate, and dislocation design when armature contact and fixed contact are opened a sluice gate, the probability of electric arc generation is reduced, and use rubber
The separation sleeve isolation fixed contact of making further reduced the probability of electric arc generation.
