It is installed embedded in the housing 70 installed in the upper portion.

The first power transmission unit 300 transfers the power of the power unit 100 to the lock bar 25 formed vertically coupled to the upper portion of the first sluice 20 to elevate the lock bar 25 in the vertical direction. By doing so, the first gate 20 is opened and closed.

The first driven shaft 310 is installed in parallel with the drive shaft 120 as the first power transmission unit 300. A first driven gear 320 having a predetermined reduction ratio is axially coupled to the first driven shaft 310 to transmit the rotational force of the drive shaft 120 to the first driven shaft 310. The first driven shaft 310 is spaced apart from the first driven gear 320 by a predetermined distance, and the first worm gear 330 is coupled to engage with the first worm wheel 350 that is axially coupled to the second driven shaft 340. The pinion gear 360 is coupled to the second driven shaft 340 by being spaced apart from the first worm wheel 350 by a predetermined distance, and the pinion gear 360 meshes with the lock bar 25 so as to vertically lock the lock bar 25. By moving to the first power transmission unit 300 is to open and close the first gate (20).

As described above, the first power transmission unit 300 may be configured of the first worm gear 330 and the first worm wheel 350 to prevent the water gate 20 from being lowered due to the weight of the first water gate 20. .

In addition, the second power transmission unit 400 transmits power generated by the power unit 100 to the winch unit 200 to open and close the second gate 30 by power, and is parallel to the driving shaft 120. Three driven shafts 410 are installed. In addition, a second driven gear 420 having a predetermined reduction ratio is axially coupled to the third driven shaft 310 to transmit the rotational force of the drive shaft 120 to the third driven shaft 410. The third driven shaft 410 is spaced apart from the second driven gear 420 by a predetermined distance, and the second worm gear 430 is engaged with the second worm wheel 450 that is axially coupled to the fourth driven shaft 440. The first pulley 460 is coupled to the fourth driven shaft 440 by being spaced apart from the second worm wheel 450 by a predetermined distance, and the belt 470 is connected to the winch part 200 by the first pulley 460. Is mounted. Accordingly, the second power transmission unit 400 transmits power to the winch unit 200.

The winch 200 is installed on the structure 50 to wind the wire 35 connected to the second sluice 30 to rotate the second sluice 30 to be opened and closed.

The winch unit 200 is connected to the second power transmission unit 400 and the wire drum 210 winding the wire 35, and extending horizontally in the direction from the wire drum 210 to the second sluice 30 Chiba 230 is provided.

The wire drum 210 is installed on top of the structure 50 to unwind or wind the wire 35 while rotating. One side of the wire drum 210 is provided with a second pulley 220 axially coupled to the rotation axis of the wire drum 210. The second pulley 220 is connected to the first pulley 460 and the belt 470 so that the wire drum 210 rotates to wind the wire 35.

Although not shown, the first and second pulleys 460 and 220 may be configured as sprockets and connected to a chain.

A support bar 230 extending horizontally in the direction of the second sluice 30 from the wire drum 210 is installed. The end of the support bar 230 is provided with a roller 235 which rotates while supporting the wire 35 wound on the wire drum 210.

Therefore, when the wire 35 connected to the lower portion of the second gate 30 is wound in the winch unit 200, the lower portion of the second gate 30 rotates to open the outlet of the flow path 60, and the wire 35 Loosen the rotation of the second gate (30) by the weight of itself to close the exit of the flow path (60) again.

Of course, the second sluice 30 normally opens and closes the outlet of the flow path 60 while rotating by buoyancy of the water in which the water level is varied.

When the second floodgate 30 is not opened in the closed state due to suspended matter, foreign matter, or the like, the water passage 60 of the waterway is closed, and when the rainy season or the water level rises, the water upstream is discharged to the downstream side. We cannot do it and there is fear of disaster.

In this case, the hydrostatic lifting device 10 of the present invention is able to forcibly open the second gate 30.

Therefore, the power switching unit 500 that can selectively transfer the power generated by the power unit 100 to any one of the first power transmission unit 300 and the second power transmission unit 400 is a sliding shaft 510, The first and second drive gears 520 and 530 installed on the sliding shaft 510 and the operation means 550 for sliding the sliding shaft 510 are provided.

Sliding shaft 510 is coaxially installed on the outer surface on the drive shaft 120 is coupled to the sliding movement left and right on the drive shaft 120.

It is formed to be. A key groove corresponding to the key is formed on the inner circumferential surface of the sliding shaft 510.

The first and second driving gears 520 and 530 are axially coupled on the sliding shaft 510 so that the first driving gear 520 meshes with the first driven gear 320 by an operation means 550. The second driving gear 530 meshes with the second driven gear 420.

When the first driving gear 520 meshes with the first driven gear 320, the second driving gear 530 and the second driven gear 420 are separated, and the second driving gear 530 is the second driven gear. In the case of meshing with 420, the first driving gear 520 and the second driving gear 530 have a predetermined distance on the sliding shaft 510 so that the first driving gear 520 and the first driven gear 320 are separated. It is installed spaced apart.

As the operation means 550, the flange 551 in which the groove is formed along the circumference of the center of the outer circumferential surface is axially coupled with the sliding shaft 510. Of course, the sliding shaft 510 may be integrally formed. The U-shaped holder 553 is mounted in the groove of the flange 551. In this case, the flange 551 may be moved left and right by the holder 553, but the flange 551 is interlocked with the sliding shaft 510. It is mounted to rotate. Accordingly, when the operation lever 555 is moved left and right, the sliding shaft 510 is slidably moved left and right on the drive shaft 120.

Although not shown, a stopper for limiting the moving distance may be installed so that the sliding shaft 510 does not move more than a predetermined distance.

Referring to the operation of the hydrological lifting device 10 of the present invention configured as described above are as follows.

Normally, the operating lever 555 of the power switching unit 500 is operated to maintain the first driving gear 520 in engagement with the first driven gear 320. When the manager rotates the handle lever 110, the first drive gear 520 coupled to the drive shaft 120 rotates to rotate the first driven gear 320, the first worm gear 330, and the first worm wheel 350. Rotate Therefore, the pinion gear 360 is rotated by the rotation of the first worm wheel 350 to move the lock bar 25 up and down to open and close the first floodgate 20.

When the second gate 30 is to be forcibly opened, the sliding shaft 510 is moved by operating the operation lever 555 of the power switching unit 500. As the sliding shaft 510 is moved, the second driving gear 530 meshes with the second driven gear 420. Accordingly, the second drive gear 530 coupled to the drive shaft 120 rotates, and the second worm gear 430, the second worm wheel 450, and the first pulley are rotated by the rotation of the second drive gear 530. The winch 200 is driven by the belt 470 by rotating the 460. When the wire drum 210 is rotated by the belt 470 to wind the wire 35, the lower portion of the second sluice 30 is rotated and opened.
