The sluice height detection unit 200 may be formed of a known open meter and the like, and may detect the height of the sluice.

The controller 300 may control the disc brake 90 based on the operation signal of the emergency drop switch 100 and the vertical height value of the floodgate detected by the floodgate height detection unit 200.

12 is a flowchart sequentially illustrating a control process of the disc brake 90 of the controller 300.

As shown in Figure 12 when the operator operated the emergency drop switch 100 in the ON state,

The control unit 300 supplies the power of the power supply unit (400 in FIG. 11) to the disc brake 90 to terminate the brake operation so that the drive shaft 211 of the driving means 20 can be reversely rotated. As a result, the floodgate can descend.

When the operator operated the emergency lowering switch 100 in the OFF state,

The control unit 300 cuts off the power supply of the disc brake 90 from the power supply unit 400, wherein the disc brake 90 has the drive shaft 211 of the driving means 20 at the forward and reverse rotation speed. The brake acts to lower the water, which may lower the descending speed of the gate.

Particularly, when the vertical height value of the descending floodgate detected by the floodgate height detection unit 200 is equal to or less than the reference height height preset in the controller 300,

The control unit 300 cuts off the power supply from the power supply unit 400 to the disc brake 90,

At this time, the disc brake 90 is to operate the brake so that the drive shaft 211 of the drive means 20 is reduced in forward and reverse rotation speed,

As a result, the descending speed of the water gate lowered by the driving means 20 which is supplied with power from the power supply unit 400 under the control of the controller 300 may be lowered.

When the vertical height value of the descending floodgate detected by the floodgate height detection unit 200 is greater than the reference height set in advance in the controller 300,

The control unit 300 controls to supply power to the disc brake 90 from the power supply unit 400,

At this time, the brake operation of the disc brake 90 is terminated so that the drive shaft 211 of the driving means 20 can be rotated forward and backward at a higher speed.

As a result, the descending speed of the water gate descending by the driving means 20 which is supplied with power from the power supply unit 400 may be increased by the control of the controller 300.

When the vertical height value of the sluice detected by the sluice height detection unit 200 is '0m', the control unit 300 may stop the operation of the driving means 20 by determining that the sluice is completely lowered. The power supply to the drive means 20 can be cut off so that the power supply unit 400.

The present invention configured as described above can easily and efficiently raise and lower the water gate, in particular, when the water level rises due to rainy season or the like, it is possible to urgently lower the water gate through the emergency lowering unit 60 as well as the conventional Since the hydrologic winch 1 and the emergency dropping unit 60 are very compatible, there is an advantage that the emergency dropping unit 60 can be more easily installed in the conventional hydrogate winch 1.
