Rotary maintenance type leakage protector

A rotary maintenance type leakage protector, comprising:

• a base;
• a leakage protection device, wherein the leakage protection device comprises a reset key, a return rotation stopper, an electromagnetic driven device and an elastic piece;
• and
• an upper cover, wherein the base is further provided with a conducting terminal that is electrically connected with the elastic piece;
• wherein the return rotation stopper is mounted on an upper part of the base and is configured to move up and down, and two sides of the return rotation stoppers are provided with protruding ends that can be abutted against the elastic piece;
• the electromagnetic driven device is disposed on a side of the upper part of the base, and the electromagnetic driven device is provided with a driven iron core, the driven iron core is protruded from the electromagnetic driven device and is movably clamped to a side wall of the return rotation stopper, and the electromagnetic driven device is able to drive the driven iron core to move so as to drive the return rotation stopper to rotate;
• the return rotation stopper is provided with a buckle block, and the reset key is sleeved with a return spring, one end of the return spring is abutted against an upper part of the upper cover, the other end of the return spring is abutted against the reset key;
• the reset key passes through the upper cover and is inserted into the return rotation stopper;
• the electromagnetic driven device in a continuous power-on state is configured to enable the driven iron core to continuously tighten the return rotation stopper, and enable the buckle block to be continuously clamped to the reset key, so as to drive the return rotation stopper to move synchronously, and the reset key is configured to enable a power-on state in which the elastic piece is in contact with the conducting terminal through the return rotation stopper;
• after the electromagnetic driven device in the continuous power-on state is powered off, the driven iron core releases the return rotation stopper, the buckle block and the reset key are out of a clamped state, and, the elastic piece is separated from the conducting terminal under an elastic force action of the elastic piece and is therefore powered off.
