Using above-mentioned technical proposal, advantages of the present invention is：The integration of permanent magnetism and manual divide-shut brake is realized, and is caused
The structure of close/open machine is simpler, compact, more facilitates close/open machine to be arranged on the shell of breaker, while effectively
Improve the stability of its work.Its operation principle is：
When carrying out permanent magnetism combined floodgate, control permanent magnet driving device action drives the first drive link and the first linking arm to transport to the left
It is dynamic, the rotation of the first drive block is realized, meanwhile, the sliding pin on the first drive block at the second linking arm props up on the second drive link the
The right-hand member of one bar-shaped trough, drives the second drive link to move right, and then realizes the rotation of output sleeve, final to drive divide-shut brake to drive
Lever, which is rotated, realizes the combined floodgate of breaker, and now the trundle on output sleeve at the 4th linking arm is located on the 3rd drive link the
The top of two bar-shaped troughs, even if now operation manual divide-shut brake component actuation is closed a floodgate, drives the 3rd drive link to act upwards,
Second bar-shaped trough will not also collide trundle, it is ensured that permanent magnetism closes a floodgate and will not disturbed by closing by hand；When need carry out permanent magnetism
During separating brake, control permanent magnet driving device action drives the first drive link and the first linking arm to move right, then the first drive block
Also reversion is driven, meanwhile, the sliding pin on the first drive block at the second linking arm props up the left end of the first bar-shaped trough, drives second
Drive link causes the output sleeve being connected with the second drive link to invert to left movement, final to drive divide-shut brake drive rod anti-
Turn to realize the separating brake of breaker.
When there is situation about having a power failure, it is necessary to when carrying out closing by hand, rotate and input rotating shaft, input gear and energy storage tooth are driven
Wheel is rotated, and at the same time, energy storage rotating shaft is rotated together with energy storage gear, and drives contiguous block around energy storage axis of rotation, so that
Stretching energy storage constantly is carried out to the first energy-stored spring, in the process, anti-lock device limits the reversion of input gear, it is ensured that
The stability of energy storage, afterwards, after contiguous block is turned over, and the first energy-stored spring is pulled into most long angle, the first energy-stored spring is rapid
Shrink, and the elastic potential energy of storage is transferred to energy storage rotating shaft, drive the biography in energy storage rotating shaft quick rotation, now energy storage rotating shaft
Moving cam and the first transmission arm are collided, and are driven the first transmission arm to swing to the right, are realized the rotation of the second drive block, meanwhile, second
Transmission arm drives the 3rd drive link to move upwards, and and then, the bottom of the second bar-shaped trough props up the 4th connection on the 3rd drive link
Trundle on arm, the 4th linking arm is pushed up, and realizes the rotation of output sleeve, the final divide-shut brake driven on breaker
Drive shaft turns, realize the combined floodgate of breaker, and now the sliding pin on the second linking arm is located at the first bar-shaped trough left end, even if subsequently
Permanent magnet mechanism is controlled to carry out feed motion after energization, sliding pin will not also drive the second drive link to act, it is ensured that closing by hand will not
The interference closed a floodgate by permanent magnetism, afterwards, callback device apply forces to clawback arm, drive the reversion of the second drive block, return to
Angle before driving cam collision, now, the second transmission arm drives the 3rd drive link to move downward, after completing to reset, and the 4th
Trundle on linking arm is in the top of the second bar-shaped trough on the 3rd drive link, realizes that the 3rd drive link is moved downward and is answered
Trundle will not be touched during position, so output sleeve will not be driven to rotate, it is ensured that the stability of "on" position；When needing separating brake
When, operation trip gear can complete the separating brake of breaker.
Preferably, the first linking arm side is provided with the 4th drive link, the 4th drive link is with being arranged on frame plate
On the second energy-stored spring connection, when the permanent magnet driving device action drive the first drive block rotate, and cause breaker close
During lock, second energy-stored spring is in extended state.When needing breaker to carry out permanent magnetism separating brake, stored up in the second energy-stored spring
The energy deposited can be inverted with the drive block of power-assisted first, help breaker quick acting switching-off so that the separating brake of breaker more efficiently, can
Lean on.
When carrying out closing by hand, driving cam and the first transmission arm carry out the collision of high intensity, stress herein at first
Maximum, in order to effectively realize the protection to driving cam and the first transmission arm, improves the service life of mechanism, and ensure biography of closing a floodgate
Dynamic is smoothed out, preferably, first transmission arm is provided with protective case, the protective case matches somebody with somebody splice grafting with driving cam
Touch.
