The utility model provides a cabinet trades electricity that this embodiment provided, its use as follows:

in the first case, as shown in fig. 4, when the electric control device of the power conversion cabinet is in the locked state, i.e. when the connecting roller 22 and the rotation center of the driving wheel 21 are both arranged to extend in the horizontal direction, the bottom of the trigger end 32 abuts on the second position switch 62; at this time, if the user is when needing to open the power exchange cabinet:

firstly, an instruction signal requesting unlocking is sent to the background through the mobile terminal, for example, a user scans a two-dimensional code arranged on the surface of the battery replacement cabinet through a mobile phone and sends an instruction requesting unlocking to the background. At this moment, the controller accepts the instruction signal of unblanking of backstage, and give the control end of motor with the instruction signal of unblanking, the control end control drive end circular telegram of motor rotates, thereby drive wheel 21 and rotate, connection gyro wheel 22 on the drive wheel 21 rotates with the connection boss 31 butt of linkage 3, when the top butt of trigger end 32 was on first position switch 61, the controller accepted the feedback signal that targets in place that the backstage sent, thereby send the stop rotation instruction to the control end of motor, the motor cuts off the power supply. At this time, the connecting roller 22 and the rotation center of the driving wheel 21 are extended in the vertical direction, the stopper pin slides upward along the guide locking groove 411, and correspondingly, the guide 71 slides downward along the guide groove 72; until the stopper pin is disengaged from the guide locking slot 411; at the same time, the linkage 3 is also pushed upward by the spring force released from the biasing restoring member 5. After unlocking, the bias reset piece 5 is in a stretched state; the electric control lock device is in an unlocking state, and as shown in fig. 3, a user can open the power exchange cabinet by opening the door plate.

In the second case, as shown in fig. 3, when the electric control device of the electricity transforming cabinet is in the unlocked state, i.e. when the connecting roller 22 and the rotation center of the driving wheel 21 are both arranged extending in the vertical direction, the bottom of the triggering end 32 abuts on the first position switch 61; at this time, if the user needs to lock the power exchange cabinet:

firstly, the door plate is buckled on the cabinet in advance, and then the controller receives a locking command signal of the background. For example, the user issues a door closing command on a mobile phone. The controller transmits the locked command signal to the control end of the motor, the control end of the motor controls the drive end to be electrified and rotated, so that the drive wheel 21 is driven to rotate, the connecting roller 22 of the drive wheel 21 is abutted and rotated with the connecting boss 31, the linkage piece 3 moves downwards along the vertical direction under the action of bias force until the bottom of the trigger end 32 is abutted on the second position switch 62, the controller receives a feedback signal sent by a background signal, so that a rotation stopping command is sent to the control end of the motor, and the motor is powered off. At this time, the connecting roller 22 and the rotation center of the driving wheel 21 are extended in the horizontal direction, and the stopper pin slides downward along the guide locking groove 411; accordingly, the guide 71 slides upward relative to the guide groove 72 until the stopper pin is stopped in the guide locking groove 411; at this time, the bias reset piece 5 is in a compressed state, and the electric control lock device is in a locked state, as shown in fig. 4, so that the locked power change cabinet is realized.

Besides the two situations, if an abnormal situation occurs in the switch process of the power change cabinet, for example, the set time for opening and closing the door body is exceeded, the controller can automatically judge that the abnormal situation is fed back to the background. Meanwhile, under the conditions of power failure or signal abnormality and failure of the driver, the linkage 3 can be pulled by manual operation, so that manual unlocking under the abnormal conditions is realized.

In the electric control lock device provided by the embodiment, because the rotation center and the geometric center of the driving wheel 21 are eccentrically arranged, the driving wheel 21 rotates to generate displacement movement to the linkage member 3 along the opening and closing direction or the locking direction, and when the movement is transmitted to the locking limiting member and the locking linkage member, the reciprocating switching of the electric control lock device between the locking state and the unlocking state can be realized. Because only rotate through drive wheel 21 and realize the removal of linkage 3, need not higher precision and can realize opening and shutting of electric control lock, greatly reduced the cost, simultaneously, only limit drive wheel 21 and 3 butt positions of linkage and can control opening and shutting of electric control lock, avoided current electric control lock structure because gear drive causes the emergence of the dead phenomenon of card easily, further improve the stability and the reliability that electric control lock device opened and shut.
