Detailed Description

The embodiment is a hydropower station gate buoyancy automatic controller, which comprises a gate frame and a gate which can slide up and down and is arranged in the gate frame, wherein the upper end of the gate frame is provided with a notch which is corresponding to the gate and can be penetrated by the gate to provide a space for the up-and-down movement of the gate. The system has 2 vertical arrangement's dead lever evenly at the gate upper end, and the system has vertical arrangement's rack on the leading flank of dead lever, corresponds the rack and is equipped with rather than the gear of meshing, links to each other through the pivot between the gear, and the pivot is rotatable to be installed on the support and is fixed in the floodgate frame upper end through the support. In this example, a gate driving motor is mounted on the right bracket, and an output shaft of the gate driving motor is coaxially connected with the rotating shaft.

In the embodiment, a circuit on the gate driving motor is connected with the motor control switch, and the gate driving motor is controlled to start, stop and turn through the motor control switch. In this example, the motor control switch is a bidirectional knife switch, and has a rotating base and upper and lower metal sheets forming the bidirectional knife switch, and a knife capable of cooperating with the upper and lower metal sheets to realize the switching function is rotatably mounted on the rotating base.
