The invention discloses a helm system locking device. The helm system locking device comprises a motor, a gear transmission mechanism, a screw-nut auxiliary mechanism, an unlocking control travel switch, an unlocking state indication travel switch, a locking control travel switch, a locking state indication travel switch, a pressing plate, a limiting block and an electric connector. The output end of the motor is connected with one end of the gear transmission mechanism. The other end of the gear transmission mechanism is connected with a screw end of the screw-nut auxiliary mechanism. A nut end of the screw-nut auxiliary mechanism is connected with the limiting block. The locking of a helm system is realized in such a way that the limiting block protrudes and clamps a locking rocker arm connected with a steering engine. Conversely, the unlocking of the helm system is realized in such a way that the limiting block retracts and releases the rocker arm. The unlocking control travel switch and the locking control travel switch are connected with a control loop of the motor in series and control the switching on and the switching off of the loop of the motor. According to the invention, the repeated switching of a locking state and an unlocking state can be realized, and the states can be indicated correspondingly, so that the helm system locking device is convenient to test, and the safety and the reliability are improved.
