Description

Floodgate winch with smart fast shutoff function and that can be remotely operated to switch between electric mode and manual mode

The present invention relates to a sluice gate having a smart high-speed order function, and more particularly, to a sluice gate lifting machine capable of remotely operating an electric mode and a manual mode and having a sluice gate high-speed order function.

In general, a sluice gate, which is a type of water treatment facility, is installed in water and sewage, urban sewage treatment plants, water purification plants, agricultural irrigation channels, and other related water channels or other drains in contact with rivers.

The sluice gate regulates the flow rate by opening/closing by elevating and descending, maintaining the depth of the water, as well as preventing the backflow of water due to flooding, etc.

For such a sluice gate, a motor-powered hoist is widely used, and the hoist is generally implemented in a manual manner when the clutch is disconnected while the electric hoist is operated.

Also, among the various types of hoists using motors, the pin jack hoist, which transmits the power of the motor to the sluice gate through the rack bar, and the drum hoist, which transmits the motor power to the sluice gate through the wire rope wound around the drum, are widely used. do.

On the other hand, in the conventional hoisting machines, the manager directly moves the operation lever to select the electric/manual switching, and in any case, the manager must visit the site and operate it.

Therefore, even when the floodgates need to be urgently closed due to floods or other disasters, it takes time for the manager to visit the site, so there is a problem in that the number of vehicles is delayed and flood damage is increased. In particular, when one manager manages several sluice gates, there is a disadvantage in that it is difficult to respond quickly.

In addition, the conventional sluice winch cannot be switched immediately due to frictional force generated in the mechanical connection structure when performing an operation to manually change the operation mode in the field, and after performing additional work to resolve the mechanical frictional force Since the operation mode switching operation is performed, there is a disadvantage in that it is difficult to make an emergency vehicle.

In addition, if access to the sluice control panel is not possible due to the loss of the access road due to a disaster, flood damage may increase as the sluice gate cannot be operated and the vehicle cannot be driven. Damage caused by malfunction of this small administrator may occur.

The clutch 180 is provided between the wheel member 170 and the power transmission unit to selectively transmit the rotational force of the wheel member 170 to the power transmission unit.

The clutch 180 may be selectively disposed at a transmission position for transmitting the rotational force of the wheel member 170 to the power transmission unit and a manual position where power transmission between the wheel member 170 and the power transmission unit is blocked.

3, 4, and 5 show a state in which the clutch 180 is disposed in the manual position, and FIGS. 6, 7 and 8 show the state in which the clutch 180 is disposed in the transmission position.

In one embodiment, the clutch 180 may be centrally coupled to the input shaft 132 so that the rotational behavior coincides with the input shaft 132 in order to transmit the rotational force of the wheel member 170 to the power transmission unit, and for selective transmission of the rotational force, the input shaft It may be configured to be movable in the axial direction of 132 .

As an example for implementing this operation, the clutch 180 is axially slidably fastened to the input shaft 132 , and rotates with the input shaft 132 through a key 181 extending in the axial direction of the input shaft 132 . may be synchronized, but is not limited thereto.

In addition, in one embodiment, the clutch 180 has a second dog gear 182 that protrudes on a surface opposite to the wheel member 170 and can be engaged with the first dog gear 172 of the wheel member 170 . can be provided

The mode conversion unit may be connected to the clutch 180 to perform an operation of moving the clutch 180 to an electric position and a manual position.

In one embodiment, the mode conversion unit may include a shaft 192 , an operation lever cover 194 , a connection lever 196 , and an operation lever 198 .

The shaft 192 is provided rotatably through the housing 131 of the upper gear unit 130 in the direction toward the clutch 180 as shown in FIGS. 3 and 6, and one end of the housing 131 is provided. It may be located inside the , and the other end may be located outside the housing 131 .

The operation lever cover 194 may be coupled to the other end of the shaft 192 to match the rotational behavior. In one embodiment, the operation lever cover 194 is a housing ( 131) may be provided to be exposed to the outside, but is not limited thereto.

The connection lever 196 is provided to connect the shaft 192 and the clutch 180 to each other, and is a medium for transmitting the rotational force of the shaft 192 to the clutch 180, and according to the rotation direction of the shaft 192, the clutch ( 180 ) may be linearly reciprocated in the axial direction of the input shaft 132 .

To this end, in one embodiment, the connecting lever 196 has one end rotatably connected to the rim of the clutch 180 as shown in FIGS. 5 to 6 , and the other end has the same rotational behavior as the shaft 192 . can be very combined.

In addition, in one embodiment, the clutch 180 may have a receiving groove 186 formed along the circumference of the clutch 180 in the central portion in the longitudinal direction as shown in FIG. 8 , and the receiving groove 186 has As shown in FIGS. 5 and 8 , the slip member 197 may be accommodated, and one end of the connection lever 196 may be rotatably hinged to the slip member 197 .

The operation lever 198 is a member provided to enable an administrator to switch between the electric mode and the manual mode by manpower when the actuator 200, which will be described later, does not operate due to a failure or the like during a power outage, and the operation lever cover 194 It is coupled to and can apply an eccentric load to one side of the rotation direction of the operation lever cover (194). That is, the operation lever 198 may be coupled to one circumferential side of the operation lever cover 194 to apply an eccentric load to the operation lever cover 194 by its own weight.

As an example, the operation lever 198 may be configured in a long bar shape to easily identify a position with the naked eye even from a distance, but is not limited thereto.

The mode conversion unit having this configuration operates the operation lever 198 or the shaft 192 and the shaft 192 coupled to the operation lever cover 194 when the operation lever cover 194 is rotated by the actuator 200 to be described later. ), the coupling lever 196 is rotated to move the clutch 180 to the electric position and the manual position according to the rotational direction.

The actuator 200 may be connected to the mode conversion unit to operate the mode conversion unit by an electric signal. That is, the mode conversion unit is a sluice gate with push button switches 201 and 202 installed on the outside of the housing 131 of the upper gear unit 130 as shown in FIG. 2 or from a distance by the actuator 200 operated by an electric signal. It is possible to switch between the electric mode and the manual mode of the winding machine 100 .

In one embodiment, the actuator 200 may operate to apply a force in one direction by an electrical signal, and may operate to remove resistance in both directions when the electrical signal is removed. In other words, the actuator 200 has a mover that moves in both directions, and when an electric signal is applied, the mover moves in one direction to temporarily apply a force to the object, and when the electric signal application is stopped, the mover is free in both directions by an external force It can operate in a movable manner.

To implement this operation, the actuator 200 may be configured as a push-pull solenoid. The push-pull solenoid can be driven in any one of the pushing direction and the pulling direction when power is supplied, that is, when current is applied to the coil. No return force occurs.

Accordingly, when the actuator 200 is implemented as a push-pull solenoid, the electric signal may be a power supply.

Meanwhile, as shown in FIGS. 4 and 7 , in one embodiment, the actuator 200 may include a first push-pull solenoid 210 and a second push-pull solenoid 220 .

Here, the first push-pull solenoid 210 has one end connected to the movable rod 212 of the first push-pull solenoid 210 and the other end eccentrically connected to the upper or lower portion of the operation lever cover 194 or the shaft 192 . The operation lever cover 194 or the shaft 192 may be rotated clockwise or counterclockwise via the first link member 214 .

In addition, the second push-pull solenoid 220 has one end connected to the movable rod 222 of the second push-pull solenoid 220 and the other end eccentrically connected to the lower or upper portion of the operation lever cover 194 or the shaft 192 . The control lever cover 194 or the shaft 192 through the second link member 224 in a counterclockwise or clockwise direction, that is, the first push-pull solenoid 210 operates the lever cover 194 or the shaft 192. can be rotated in the opposite direction to the direction of rotation.

3 to 7, the first push-pull solenoid 210 may be connected to the first link member 214 connected to the upper portion of the operation lever cover 194, and the second push-pull solenoid ( 220 may be connected to the second link member 224 connected to the lower portion of the operation lever cover 194, which is a position opposite to the connection portion of the first link member 214 with respect to the center of the operation lever cover 194 .

In addition, both the first push-pull solenoid 210 and the second push-pull solenoid 220 may be configured as a pull type in which the movable rods 212 and 222 are drawn in when power is supplied.

In this configuration, as shown in FIGS. 3 and 4, when the second push-pull solenoid 220 receives an electric signal and drives, the movable rod 222 of the second push-pull solenoid 220 is drawn in and the operation lever cover ( 194) to rotate the operation lever cover 194 and the shaft 192 clockwise by pulling the lower part. And, as the shaft 192 rotates clockwise, the clutch 180 moves in a direction away from the wheel member 170, so that the clutch 180 is placed in the manual position, so that the sluice lift 100 is switched to the manual mode. can

At this time, since no electric signal is applied to the first push-pull solenoid 210, the operation lever cover 194 can rotate clockwise without resistance.

Conversely, as shown in FIGS. 6 and 7 , when the first push-pull solenoid 210 receives an electric signal and is driven, the movable rod 212 of the first push-pull solenoid 210 is drawn in and the operation lever cover 194 . Pull the upper part of the operation lever cover 194 and the shaft 192 to rotate counterclockwise. And, as the shaft 192 is rotated counterclockwise, the clutch 180 moves in the direction of the wheel member 170 so that the clutch 180 is disposed in the electric position, so that the sluice lift 100 can be switched to the electric mode. At this time, since no electric signal is applied to the second push-pull solenoid 220, the operation lever cover 194 can rotate counterclockwise without resistance.

On the other hand, as shown in FIGS. 6 to 8 , when the clutch 180 is disposed in the electric position in the electric mode of the sluice gate lifter 100 , the first dog gear 172 of the wheel member 170 and the clutch 180 ) of the second dog gear 182 meshes with each other, so that rotational force transmission between the wheel member 170 and the clutch 180 is possible.

Accordingly, the rotational force of the driving motor 120 is transmitted to the clutch 180 through the wheel member 170 so that the input shaft 132 having the same rotational behavior as the clutch 180 can receive the rotational force of the driving motor 120 . there will be

Conversely, as shown in FIGS. 3 to 5 , when the clutch 180 is placed in the manual position in the manual mode of the sluice gate lifter 100 , the first dog gear 172 and the clutch 180 of the wheel member 170 . ) of the second dog gear 182 is spaced apart from each other.

Accordingly, the rotational force of the driving motor 120 is not transmitted to the clutch 180, and at this time, even when the driving motor 120 operates, the wheel member 170 and the input shaft 132 are rotatably coupled to each other independently of each other. Therefore, the rotational force of the wheel member 170 is not transmitted to the input shaft 132 .

In addition, in one embodiment, when the sluice gate lifter 100 is switched to the manual mode, the input shaft 132 because the rotation restraining force of the driving motor 120 in the non-operational state does not inhibit the rotation of the input shaft 132 . ) and the output shaft 142 interlocking with the input shaft 132 may be freely rotated. Accordingly, the sluice gate 20 can descend by its own weight.

At this time, since the descending speed due to its own weight is 2 to 5 times faster than the descending speed by the driving motor, a high-speed order is possible.

On the other hand, the first dog gear 172 and the second dog gear 182 described above need to be disposed at positions where their respective gear teeth do not face each other, that is, a misaligned position with the counterpart gear teeth in order to mesh with each other. . If, in a state where the first dog gear 172 and the second dog gear 182 face each other, the first dog gear 172 and the second dog gear 182 do not mesh with only the linear movement of the clutch 180 This can happen.

Therefore, while minimizing the probability that the first dog gear 172 and the second dog gear 182 are disposed to face each other, the rotational force of the wheel member 170 can be symmetrically transmitted to the clutch 180 without being eccentric. , in one embodiment, the first dog gear 172 may be provided with a pair symmetrically with respect to the input shaft 132 , and the second dog gear 182 may also be provided with a pair symmetrically with respect to the input shaft 132 .

In addition, as shown in FIG. 9, in one embodiment, at the corners of both ends of the front ends of the first dog gear 172 and the second dog gear 182, an inclined surface 174 inclined in the opposite direction of the front end is formed. can be formed.

Here, both sides of the front end mean both sides in the rotational direction of the wheel member 170 and the clutch 180 , and the opposite direction of the front end is opposite to the protrusion direction of the first dog gear 172 and the second dog gear 182 . means

As described above, the inclined surfaces 174 and 184 formed on the first dog gear 172 and the second dog gear 182 have the first dog gear 172 and the second dog gear 182 facing each other so that they cannot engage. It has the advantage of further reducing the probability of occurrence. That is, the position where the first dog gear 172 and the second dog gear 182 do not mesh may be reduced by the width of the inclined surfaces 174 and 184 .

Specifically, when the clutch 180 moves from the rotational position in which a portion of the first dog gear 172 and the second dog gear 182 overlaps each other near the edge, the first dog gear 172 is The inclined surface 174 and the inclined surface 184 of the second dog gear 182 may slide along the opposite inclined surfaces 184 and 174 to allow the clutch 180 to move to the transmission position.

At this time, in order to move the clutch 180 to the electric position while the first dog gear 172 and the second dog gear 182 slide together along the inclined surfaces 174 and 184, the clutch 180 and the wheel member 170 ), at least one of the inclined surfaces (174, 184) must be rotated more than the width.

However, the rotation of the clutch 180 is restricted by the input shaft 132 whose rotation is restricted by the weight of the sluice gate 20 , and the rotation of the wheel member 170 is restricted by the driving motor 120 in an inactive state. . For this reason, even when the inclined surfaces 174 and 184 are in contact with each other, the clutch 180 cannot move to the transmission position.

To solve this point, in one embodiment, when the electric mode switch or the manual mode switch is pressed, the driving motor 120 rotates in one direction for a preset time (eg, about 1 second) by an automatic control program. The wheel member 170 is rotated. At this time, since the push-pull solenoids 210 and 220 continue to operate until the operation is completed, when the first dog gear 172 deviates from the facing surface of the second dog gear 184, the wheel member 170 and the clutch 180) are combined, so that the accuracy of the operation can be secured.

In particular, this configuration has the advantage of significantly reducing the probability of occurrence of a situation in which the administrator has to visit the sluice gate 100 directly when the sluice gate lifter 100 is switched from the manual mode to the electric mode.

On the other hand, the sluice gate lifter 100 according to an embodiment of the present invention may further include a spring 136 for elastically supporting the rotation shaft 122 to be movable in the axial direction.

As shown in FIG. 10 , the spring 136 may perform a function of notifying an administrator that an abnormality has occurred in the opening/closing operation of the sluice gate 20 through the axial position of the rotation shaft 122 . For example, when the sluice gate 20 does not ascend or descend according to the operation of the driving motor 120 due to contaminants generated in the sluice gate 20, the driving motor 120 continues in a state in which the wheel member 170 cannot rotate. By rotating the rotation shaft 122 is moved in the axial direction, it is possible to perform an abnormal situation alarm by notifying the manager of the position of the rotation shaft 122 mechanically or electronically.

On the other hand, in one embodiment, the operation lever 198 of the above-described mode conversion unit applies an eccentric load to the operation lever cover 194 and the shaft 192 so that the clutch 180 moves to the manual position when no external force is applied. It can be configured to apply.

4 and 5, the operation lever 198 is configured to extend downward in the manual mode, and when there is no external force, the clutch 180 is operated by the weight of the operation lever 198 Manual position may be maintained. This configuration can prevent the clutch 180 from moving to the electric position through the weight of the operation lever 198 while the sluice gate 20 descends by its own weight in the manual mode.

Conversely, in the electric mode, since the self-weight of the sluice gate 20 is always applied to the clutch 180, on the contact surface between the first dog gear 172 of the wheel member 170 and the second dog gear 182 of the clutch 180 Due to the generated frictional force, the clutch 180 may not return to the manual position despite the weight of the operation lever 198 .

When the manual mode switch is pressed to switch to the manual mode, the electric motor 120 rotates in the direction in which the sluice gate descends for about 1 second to rotate the wheel member 170 and the first dog gear 172 of the wheel member 170 When the frictional force generated on the contact surface between the second dog gear 182 of the clutch 180 is resolved, the push-pull solenoid 220 continues to operate until the operation is completed, so the clutch 180 moves to the manual position and the second The dog gear 182 is spaced apart from the first dog gear 172 .

On the other hand, when a plurality of sluice winches 100 are installed adjacent to each other in one field, a sluice gate high-speed blocking system capable of remotely operating an electric mode and a manual mode can be applied to each sluice winch. For example, a control panel capable of remotely controlling each of the plurality of sluice winches 100 may be installed at an easily accessible location at the site where the plurality of sluice winches 100 are installed.

On the other hand, as described above, the sluice gate lifter 100 according to an embodiment of the present invention may include a communication modem M for applying an electric signal to the actuator 200 as shown in FIG. 11 .

In one embodiment, the communication modem (M) is configured to communicate with the manager's terminal in a wired or wireless way, and can transmit a status signal of the actuator 200 to the manager, and to control the actuator 200 from the manager. can receive a control signal for

In an embodiment, the communication modem M may convert the control signal received from the manager into an electric signal for controlling the actuator 200 through the control unit C and apply it to the actuator 200 .

In addition, the control unit C may be provided with a button capable of operating the actuator 200 in the field and a display device for displaying the operation mode of the sluice gate lifter 100 .

Since the sluice gate lifter 100 according to an embodiment of the present invention as described above can switch between the electric mode and the manual mode by using the actuator 200 capable of remote control, the sluice gate lifter 100 installed in a plurality of places It has the advantage that it can be managed conveniently by one manager, and a quick response is possible when an emergency order is required.

Although the present invention has been shown and described with respect to specific embodiments, various modifications and changes can be made to the present invention by those skilled in the art without departing from the spirit and scope of the present invention as set forth in the claims below. Let's make it clear that it can be done.
