In addition to the torque limiter 36, a counter limit switch 37, a current limiter 38, and the like are provided as safety devices. Among them, the counter limit switch 37 is a device that detects the number of rotations of the motor 10 and stops the motor 10 to avoid danger when the number of rotations exceeds a predetermined number. The current limiter 38 is a device that detects the current value of the motor 10 and stops the motor 10 to avoid danger when the current flowing through the motor 10 exceeds a predetermined value.

In the case where an engine is used as the power drive source, the start of the engine can be facilitated by providing a centrifugal clutch, though not shown.

That is, when the operator operates the push button switch 33 shown in FIG. 1 to start the opening operation of the sluice or the valve, the motor 10 starts rotating. After the motor 10 starts rotating, the counter limit switch 37 and the current limiter 39 do not detect an abnormality such as an excessive number of rotations of the motor 10, and if the motor 10 is not stopped, the motor 10 is stopped. The rotational driving force is transmitted to the speed reducer 15. In the speed reducer 15, the rotation generated by the motor 10 is reduced, and the rotational driving force is amplified with this reduction. The rotational driving force amplified by the speed reducer 15 is transmitted to the torque limiter 36. The torque limiter 36 detects the torque of the inputted rotational driving force, and when the torque exceeds a predetermined set value, the motor 10 is stopped. On the other hand, when the torque is equal to or less than the predetermined set value, the rotational driving force is transmitted to the operation shaft 50 via the flexible shaft 20. When the rotational driving force is transmitted to the operation shaft 50, the operation shaft 50 rotates. With the rotation of the operation shaft 50, the dedicated handle 51a provided with the operation shaft 50 rotates. Further, a water gate or a valve opening / closing mechanism (not shown) is connected to the operation shaft 50 so that the water gate or the valve can be opened by rotation of the operation shaft 50.

The path for opening the sluice or valve has been described above. When closing the sluice or valve, the motor 10 is rotated in the reverse direction to open the sluice or valve with respect to the flexible shaft 20 and the operation shaft 50. It is sufficient to give a rotation in the direction opposite to the direction of rotation.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and includes various modifications. For example, a connector shown in FIG. 6 may be used as the connector.
