It relates to a hydrostatic winker including a planetary gear unit including a sun gear connected to a worm gear set and a worm gear set connected to a manual unit. The cam and worm gear set allow electric / manual operation without an electric / manual conversion lever. Even if only manual operation is possible, it is possible to close the gate quickly. It is possible to close the gate by quickly descending the gate using the descent lever, but there is a problem that the gate may be damaged due to the speed of descent of the gate.

Hereinafter, an embodiment of a hydrostatic winch that enables manual descent control of the present invention will be described in detail with reference to the accompanying drawings. The scope of the present invention is not limited to the following embodiments.

1 is a cross-sectional view schematically showing an embodiment of the hydro-winder capable of manual descent control of the present invention.

The hydrologic winch capable of the manual descent control of the present invention is largely comprised of a housing 10, a drive means 20, a switching clutch means 30, a reducer 40 and a manual operation unit 50.

The driving means 20 is provided on one side of the housing 10 as shown in Figure 1 for automatically lowering and raising the water gate, it is made of an electric motor or the like.

The drive gear 210 is fixed to the drive shaft of the drive means 20, and the drive gear 210 is disposed in the housing 10.

In addition, the switching clutch means 30 is connected so that the rotational force of the driving gear 210 can be transmitted, and the shift gear 310 and the clutch gear 320 which are bitten by each other according to manual and electric switching are separated, thereby providing a clutch function. Is exerted.

The reducer 40 is coupled to interlock with the transmission gear 410 is connected to the switching gear 310 of the switching clutch means 30, the rotary shaft 420 is provided so that the chain and the like connected to the water gate can be connected. .

2 is a cross-sectional view schematically showing the configuration of a manual operation unit which is an embodiment of the present invention, Figure 3 is a view schematically showing a coupling structure of one side of the rotating plate and the stopper.

The manual operation unit 50 is for an administrator to urgently drop the floodgate in case of an emergency such as a flood or to manually lower or raise the floodgate.

The manual operation unit 50 includes a rotating shaft 510, a rotating gear 520, one side rotating plate 530, a stopper 540, a brake plate 550, the other side rotating plate 560, and a manual handle 570. do.

The rotating shaft 510 is installed to be rotatable in the housing 10.

The rotary gear 520 is directly or indirectly coupled to one side of the rotating shaft 510, and meshes with the switching gear 310 when the switching clutch means 30 is manually switched.

The rotary gear 520 may be directly fixed to one side of the rotary shaft 510, but the rotary gear 520 to one side of the rotary shaft 510 as shown in Figure 2 to implement the self-weighting function It can be installed to be rotatable. At this time, the axis of the rotary gear 520 is installed in the same way as the axis of the rotary shaft 510.

The guide member 582 is coupled to the rotary shaft 510 in a spline manner to move left and right, and a friction surface is formed on a surface facing the rotary gear 520, and the guide member 582 is rotated by the rotary gear 520. An elastic member 584 elastically supporting toward the side may be provided.

As the friction surface of the guide member 582 is normally rubbed with the other side of the rotary gear 520 by the elastic member 584, the rotary gear 520 is maintained in a braked state.

The elastic member 584 is composed of a compression spring or the like.

The guide member 582 is moved in the opposite direction on the rotary gear 520 side by the self-lowering lever 586. As the guide member 582 is moved by the self-lowering lever 586, the braking of the rotary gear 520 is released by the friction surface of the guide member 582, so that the water gate drops.

An annular groove 582a is formed in the guide member 582. A connecting member 588 is provided between the guide member 582 and the self-lowering lever 586 to convert the rotational force of the self-lowering lever 586 to the left and right moving force of the guide member 582.

The connecting member 588 has a rotary bar 588a having an upper end fixed to an upper side of the rotary shaft 510 and a lower end aligned with a lower side of the rotary shaft 510, and the middle of the rotary bar 588a. A horizontal bar 588b extending in the direction of the guide member 582 and having a fixing protrusion 588b1 inserted into an annular groove 582a of the guide member 582 at one end thereof, and the rotating bar 588a. It consists of a fixed bar (588c) extending in the direction orthogonal to the rotation axis 510 at the lower end of the.

The self-lowering lever 586 has a lever body 586a having an upper end axially fixed to a lower side of the fixing bar of the connection member 588, and is formed to extend at an upper end of the lever body 586a, so that the connection member 588 is formed. It consists of an extension tip 586b disposed on one side of the fixing bar.

When the self-weighting lever 586 is rotated to the other side, the extension tip 586b is rotated to one side while rotating the fixing bar 588c of the connection member 588 in one direction, that is, the connection member 588 ) Rotates clockwise at a predetermined angle, the fixing protrusion 588b1 formed on the horizontal bar 588b of the connecting member 588 moves the guide member 582 in the other direction. As a result, as the guide member 582 is moved in the other direction, the friction surface of the guide member 582 is spaced apart from the rotary gear 520 to release the braking state of the rotary gear 520.

The one side rotating plate 530 is rotatably installed on the rotation shaft 510 at a position spaced a predetermined distance from the other side of the guide member 582.

And the stopper 540 is to block the one side of the rotating plate 530 is rotated in the water direction of the rotation shaft 510.

As shown in FIG. 2, the ratchet gear part 532 is formed at the one side rotating plate 530. The ratchet gear part 532 may be integrally formed on one side of the one side rotating plate 530 as shown in FIG. 2, but may be formed on the circumferential surface of the one side rotating plate 530.

The stopper 540 is fixed to the ratchet gear part 532 of the one side rotating plate 530, and is locked by a torsion spring.

The stopper 540 prevents the one side rotating plate 530 from rotating in the hydrologic lowering direction of the rotating shaft 510, but does not block the one side rotating plate 530 from rotating in the opposite direction, thereby rotating in the opposite direction. It is possible.

The brake plate 550 is screwed to the rotation shaft 510 which is the other side of the one rotation plate 530. In particular, the braking plate 550 is screwed to the rotation shaft 510 is moved in the direction of the one side rotating plate 530 when the rotation shaft 510 rotates in the direction of the hydrologic lowering.

The other side rotating plate 560 is disposed on the other side of the brake plate 550 and is rotatably installed on the rotating shaft 510. When the brake plate 550 rotates counterclockwise, the brake plate 550 rubs against the other rotating plate 560. In this state, when the brake plate 550 continues to rotate counterclockwise, the rotation shaft 510 is rotated. ) Is forcibly rotated counterclockwise, i.e. When the lowering of the water gate is prevented by an obstacle or the like, the braking plate 550 may be rotated counterclockwise to forcibly lower the water gate.

Next, the manual handle 570 rotates the brake plate 550 in the direction of the one side rotating plate 530 or the other side of the rotating plate 560 to manually lower or manually raise the water gate. It is sufficient if it is the structure which can rotate the copper plate 550.

The manual handle 570 is axially fixed to the housing 10 as shown in FIG. The manual handle 570 is fixed to the housing 10 to have the same axis as the axis of the rotation shaft 510.

The outer diameter of the brake plate 550 is larger than the outer diameter of the other rotating plate 560, and the connection member 575 is provided to connect the edge of the brake plate 550 to the shaft of the manual handle 570. do.

4 is a view schematically showing a state in which the manual handle is rotated counterclockwise.

When the manual handle 570 is rotated in the counterclockwise direction, which is the downward direction of the sluice, as shown in FIG. 4, the brake plate 550 screwed to the rotation shaft 510 is the other side opposite to the one rotation plate 530. Moving in the direction to release the braking state of the rotating shaft 510 due to the friction between the one side rotating plate 530 and the braking plate 550, the one side rotating plate 530 is counterclockwise by the stopper 540 Even though the rotation is blocked, the rotating shaft 510 and the rotating gear 520 rotate in the downward direction of the sluice, so that the sluice is lowered.

In this case, if the manager continuously rotates the manual handle 570 in the counterclockwise direction, the braking release state of the rotating shaft 510 is maintained by the friction between the one side rotating plate 530 and the braking plate 550 so that the water gate is lowered. Done. However, when the manager stops rotating the manual handle 570 in the counterclockwise direction, the rotating shaft 510 is moved in the state in which the brake plate 550 is moved in the other direction opposite to the one rotating plate 530. The brake plate 550 is moved by the rotation of the rotation shaft 510 to move in one direction of the rotational plate, that is, in one direction, so that the brake plate 550 rubs against the one rotation plate 530. Accordingly, the rotation shaft 510 is blocked from being rotated in the counterclockwise direction by the stopper 540 which blocks the one side rotating plate 530 from being rotated in the counterclockwise direction, and thus the descending of the water gate is stopped.

As described above, there is an advantage in that the convenience of operation is greatly improved, such as stopping the descending or descending of the water gate by only rotating the manual handle 570 in the counterclockwise direction without requiring a plurality of manipulations.

In addition, by adjusting the rotational speed of the manual handle 570, the administrator can adjust the descending speed of the water gate. That is, when the administrator rotates the manual handle 570 slowly in the counterclockwise direction, the friction and release of the brake plate 550 and the one side rotating plate 530 are repeated and the water gate is slowly lowered, and the manual handle 570 ), The water gate descends at a high speed because the braking plate 550 continues to be in a state where friction with the one side rotating plate 530 is released.

5 is a view schematically showing a state in which the manual handle is rotated counterclockwise to forcibly lower the gate.

On the other hand, when the fall is prevented by the obstacle, if the manager continues to rotate the manual handle 570 in the counterclockwise direction, the braking plate 550 along the thread of the rotary shaft 510 in the other direction It is moved to the friction with the other side of the rotating plate 560, thereby forcibly rotating the rotating shaft 510 in the counterclockwise direction of the downward direction of the sluice.

That is, when the braking plate 550 moves in the other direction and rubs with the other rotating plate 560, the one rotating plate 530 is rotatably installed on the rotating shaft 510 so that the one rotating plate 530 is half. Since the stopper 540 blocking the rotation in the clockwise direction does not block the rotation of the rotation shaft 510 in the counterclockwise direction, friction between the braking plate 550 and the other rotating plate 560 may occur. The rotation shaft 510 may be forced to rotate counterclockwise.

6 is a view schematically showing a state in which the manual handle 570 is rotated in the clockwise direction.

Next, when the manual handle 570 is rotated in the clockwise direction opposite to the descending direction of the floodgate, the brake plate 550 rotates clockwise together with the one side rotation plate 530, and thus the rotation shaft 510. ) Is rotated clockwise. That is, as the rotary shaft 510 is rotated in the clockwise direction, the water gate is lifted upward.

In this case, when the manager stops the rotation of the manual handle 570 while lifting the water gate by rotating the manual handle 570 clockwise, the one side rotating plate 530 which maintains friction with the brake plate 550 is Since the rotation in the counterclockwise direction is blocked by the stopper 540, the sluice remains lifted.

Thus, even when lifting the water gate, there is an advantage that the manual handle 570 can be rotated clockwise to lift the water gate without operating a separate lever or the like.
