The technical scheme is that a shell formed by the first accommodating piece and the second accommodating piece is T-shaped or L-shaped, and the transmission cavity and the driving cavity are communicated at the connecting part of the first accommodating piece and the second accommodating piece. By the arrangement, the first accommodating part can be made very thin, and one side or two sides of the first accommodating part are used for expanding and connecting the circuit breaker.

The further technical scheme is that the driving mechanism comprises a motor, the axis of the rotating shaft of the motor and the axis of the rotating shaft of the linkage mechanism are arranged in the same direction, the transmission mechanism comprises a transmission cable or a transmission belt, the transmission cable or the transmission belt is sleeved on the rotating shaft of the motor and is connected with the linkage mechanism and drives the linkage mechanism to rotate along the rotating shaft of the linkage mechanism. So, adopt the transmission mode of transmission cable or drive belt, it is not high to transmission space requirement, guarantee that the width of first holding piece can not be too big, guarantee the lateral expansion width.

The further technical scheme is that the guide mechanism is a guide post or a guide pulley.

The technical scheme is that the linkage mechanism comprises a shaft portion and a driving portion, the shaft portion is fixedly connected with the driving portion, the driving portion is provided with a sliding groove, the transmission mechanism further comprises a stop joint, the stop joint is fixed on a transmission cable or a transmission belt, the stop joint is limited in the sliding groove, the transmission cable or the transmission belt is used for driving the stop joint to slide along the sliding groove, and the stop joint moves to the end portion of the sliding groove and then can drive the driving portion to rotate around the shaft portion.

As one skilled in the art will know, the opening and closing mechanism of the circuit breaker is provided with a locking device, the opening and closing mechanism has two stable states of an opening position and a closing position, and the other stable state of a transfer position is an unstable state. Adopt the utility model discloses the structure can be so that when motor drive mechanism separating brake, can drive divide-shut brake mechanism to "separating brake position", then rely on the quick completion separating brake operation of mechanism's internal design, make its influence that does not receive motor drive mechanism's inertia, motor own rotational speed limited these two factors. Specifically, when the stop joint does not reach the groove end, the movement of the transmission cable or the transmission belt and the linkage mechanism is independent, the stop joint is limited in the sliding groove, and when the transmission cable or the transmission belt drives the stop joint to slide in the groove and reach the groove end, the transmission part drives the linkage mechanism to rotate.

The working principle is as follows: when the switching-on position just arrives, the stop piece clings to the lower end of the sliding groove, the transmission piece drives the linkage mechanism to rotate to the switching-on position, and the linkage mechanism keeps the state unchanged when the switching-on position is reached because the switching-off and switching-on mechanism has the locking function.

When preparing to open the floodgate, the driving medium is pulled up, and the stopper goes upward, and the stopper freely removes in the sliding tray, and the link gear is not influenced and keeps in the position of closing the floodgate.

After the preparation action of opening the brake is finished, the stop piece reaches the upper end of the sliding groove, and the preparation work of opening the brake is finished. If the transmission piece continues to move upwards, the linkage component is driven. This state is the normality when closing a floodgate, that is to say closing a floodgate and will make the preparation of separating brake after accomplishing, consequently the utility model discloses there is a time of preparing from the state that the position of closing a floodgate just arrived to the state of accomplishing the preparation action of separating brake, need not to wait like this again when needing the separating brake to change the state of preparing the action of separating brake from the state that the position of closing a floodgate just arrived again, the time of saving tripping operation.

When the brake is to be opened, the transmission part is pulled upwards, the linkage mechanism is driven to rotate clockwise, but the displacement is limited at the moment of starting, the locking state of the switching mechanism is not released, and the switching mechanism is still in the switching state.

As one skilled in the art will know, the opening and closing mechanism of the circuit breaker is provided with a locking device, the opening and closing mechanism has two stable states of an opening position and a closing position, and the other stable state of a transfer position is an unstable state. Adopt the utility model discloses the structure can be so that when 5 separating brake of motor drive mechanism, can drive divide-shut brake mechanism to "separating brake position", then rely on the quick completion separating brake operation of mechanism internal design, make its influence that does not receive motor drive mechanism 6's inertia, motor own rotational speed limited these two factors. Specifically, when the stop joint 18 does not reach the groove end, the movement of the transmission cable 8 or the transmission belt is independent from the movement of the linkage mechanism 4, the stop joint 18 is limited in the sliding groove 19, and when the transmission cable 8 or the transmission belt drives the stop joint 18 to slide in the groove and reach the groove end, the transmission part drives the linkage mechanism 4 to rotate.

As shown in fig. 7, the working principle is as follows: when the switching-on position is just reached, the stop piece is tightly attached to the lower end of the sliding groove 19, the transmission piece drives the linkage mechanism 4 to rotate to the switching-on position, and the linkage mechanism 4 keeps the state unchanged at the switching-on position because the switching-on and switching-off mechanism has a locking function.

When the opening is ready, the transmission part is pulled upwards, the stop piece moves upwards, the stop piece freely moves in the sliding groove 19, and the linkage mechanism 4 is not influenced and is kept at the opening position.

After the opening preparation operation is completed, the stopper reaches the upper end of the slide groove 19, and the opening preparation operation is completed. If the transmission piece continues to move upwards, the linkage component is driven. This state is the normality when closing a floodgate, that is to say closing a floodgate and will make the preparation of separating brake after accomplishing, consequently the utility model discloses there is a time of preparing from the state that the position of closing a floodgate just arrived to the state of accomplishing the preparation action of separating brake, need not to wait like this again when needing the separating brake to change the state of preparing the action of separating brake from the state that the position of closing a floodgate just arrived again, the time of saving tripping operation.
