The present invention relates to a four-way dam outlet opening and closing device for driving a valve installed to open and close the four-way dam outlet, more specifically, by installing a motor required for remote control of valve opening and closing in a safe position from water, It is configured to transmit power by torsional rotation of the flexible rotary shaft between the controlled motor and the valve installed in the outlet, so that the valve can be opened and closed by the remote control of the motor and the valve can be opened and closed in the field. Relates to a device.

Sabang Dam is a facility that is used to prevent the damage of the downstream side caused by the soil by filtering the landslides or the soils that are swept away by the valley water and flowing only the pure water. Looking at the structure of the four-side dam for this purpose is generally installed in the form of a dam across the upstream valley, the lower part is installed a number of outlets, the passage for the upstream water flows downstream.

In addition, by installing a valve in the outlet, a certain amount of water is stored in the four sides of the dam to provide a habitat for fish or as a water for irrigation or forest fire use.If the water level stored in the four sides is high, the valve is opened to control the water level. do.

Therefore, the four-side dam is provided with an opening and closing device for opening and closing the valve installed in the outlet, this opening and closing device may be used as the opening and closing device installed in the general dam, beams, embankments, as well as the four-side dam. Conventional technologies related to switchgear include Patent Publication No. 10-2006-0121780, Patent Publication No. 10-2005-0102202, Patent Publication No. 10-2007-0067028, Utility Model Registration No. 20-0320594, and the like. Looking at the above-described prior art, in general to move the water gate to open and close the discharge port up and down to open or close or rotate the water gate to open and close. Then, the power (motor or manual knob) for opening and closing the water gate is arranged at the top of the dam.

Here, looking at the installation location, size, number of installation and the purpose of the installation of the four sides dam, the discharge port of the four sides dam is installed in the lower portion of the four sides dam, to send the valley water downstream when the flow of the valley water flowing from the upstream is small, the valve or the water gate It is used to maintain the level of freshwater valley water properly even if the flow rate of the valley water is small. The discharge port is generally smaller in size than general dams or beams because it is not discharged at a high flow rate at a time. There are not many installations. When the inflow rate of valley water is very large, it has a structure of overflowing for the purpose of installing the four sides dam.

In consideration of the installation location, size, number of installations, and the purpose of installation of the outlet, the four-side dam actually installed in the installation, the valve is installed in the outlet, and the manual knob fixed to the valve as a power source for driving the valve to directly open and close the valve.

However, since the four sides dam is not a dam where the manager resides, the manager periodically visits and monitors or installs a surveillance camera or a water level meter to remotely monitor the situation of the four sides dam. Or as a dam to repair, the manager has to go upstream directly to open and close the valve. Moreover, in order to turn the manual knob of the valve installed in the outlet, there is a difficulty to go down the four sides of the dam. Accordingly, it is very difficult to open and close the valve at an appropriate time.

In addition, due to the structural characteristics of the four-side dam overflowing the valley water, it is difficult to install a power unit for opening and closing each valve, and if a motor is installed near the valve, there is a risk of a short circuit accident.

Therefore, there is a need for an opening and closing device having a structure in which a motor is installed at a position that can be used without a risk of a short circuit accident, while providing a motor to remotely open and close the valve installed at the discharge port of the four sides dam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3 are diagrams for explaining a remotely controlled four-way dam outlet opening and closing device according to an embodiment of the present invention, Figure 1 is a simplified perspective view of a four-sided dam installed the present invention, Figure 2 is a configuration diagram of the present invention 3 is a block diagram of the controller 60.

Prior to describing the four-way dam discharge opening and closing device according to the present invention, first, the structure of the four-way dam will be briefly described with reference to FIG.

The four-sided dam 1 is installed in the form of a dam or a tuft across the valleys, and forms an upstream portion 4 lower than the height of the dam shoulders 3 between the dam shoulders 3 in contact with the valleys on both sides. When the number of valleys flowing in is large, the water flows through the upstream portion 4 between the dam shoulders 3 to be discharged downstream. In addition, a plurality of outlets 2 are formed in the lower portion of the four-side dam 1 so as to penetrate from the upstream to the downstream side, so that a small amount of valley water is continuously introduced into the downstream through the outlet 2. Here, since the valley water needs to be stored at the four sides of the dam 1 at a predetermined level for the purpose of providing a habitat for fish, supplying the surrounding water, or comparing water for arson fire prevention, a valve is installed at the outlet 2 to provide a water level. Adjust

In recent years, a monitoring device for remotely monitoring all four dams is generally installed in a dam shoulder 3 which is safe from water.

Since the four-sided dam 1 flows to the upstream part and discharges along the slope toward the downstream side when the inflow of the valley water is large, the discharged water also flows toward the outlet 2 on the lower side, and the electric power is near the outlet 2. If a motor is installed and the valve is driven, there is a risk of a short circuit accident, and there is a risk of a short circuit accident even in the wire connected to the electric motor. For this reason, although a valve having a manual knob turned by hand is installed in the outlet 2, such a valve has a problem that cannot be controlled remotely.

Accordingly, according to an embodiment of the present invention, by installing an electric motor in a place safe from water (for example, the dam shoulder shown in Figure 1), and configured to transmit the rotational power of the electric motor to the valve, as well as remote control And manually controllable.

1 to 3, the four-way dam outlet opening and closing device according to the embodiment of the present invention is installed at a position where there is no risk of an electrical short-circuit accident caused by water provided from a valve 20 installed at the four-way dam outlet. Opening and closing operation by the rotation means, for this purpose, the pipe 30 is connected between the reducer 30, the rotation means 50 and the reducer 30 connected to the valve 20 and inserted into the pipe 42 flexible It comprises a rotating shaft 40, a rotating means 50 for rotating one end of the flexible rotating shaft 40, and a controller 60 for controlling the operation of the rotating means 50.

The flexible rotating shaft 40 is manufactured in the form of an elongated wire and can be bent, but there is almost no difference in the rotation angle between one end rotation angle and the other end when the other end is rotated by twisting, ie, rotation by holding one end. It is made of one material. As an example of such a flexible rotary shaft 40, since a plurality of steel wires can be twisted like a wire rope used in the lawn mower shown in Korean Patent Laid-Open Publication No. 10-2011-0048755, the material and shape of the flexible rotary shaft 40 Omit the description.

The flexible rotating shaft 40 is installed to start from the rotating means 50 to the valve 20, and after pipe 42 is piped between the rotating means 50 and the valve 20, the pipe 42. It is installed by inserting it in. At this time, the pipe 42, by using a thickness that can be inserted into the flexible rotary shaft 40 to allow the flexible rotary shaft 40 to rotate smoothly therein, the discharge port 2 in all directions dam By installing a plurality of valves to install the valve 20 according to the number and position of the discharge port (2), generally can not be piped in a straight line from the installation position of the rotation means 50 to each valve 20, You will use the sex tube. Even if the pipe 42 is a flexible pipe, the flexible rotating shaft 40 also has flexibility, as described above, and thus can be smoothly rotated inside.

On the other hand, when the pipe 42 is bent to the pipe bent, since the friction with the flexible rotating shaft 40 in the bent portion increases, as shown in FIG. 2, the flexible rotating shaft 40 is spaced apart from each other in the longitudinal direction A plurality of bearings 41 are extrapolated. At this time, since the flexible rotating shaft 40 having the bearing 41 fitted to the outer circumferential surface should be inserted into the pipe 42, by using the pipe 42 having an inner diameter larger than the outer diameter of the bearing 41, the flexible rotating shaft 40 Easy insertion and smooth rotation.

In this way, the flexible rotary shaft 40 inserted into the pipe 42 is installed in one end of the rotating means 50 and the other end of the reducer 30 in the inside of the reducer 30, thereby rotating the one end. Let the other end rotate as well.

The rotating means 50 is configured to rotate one end of the flexible rotating shaft 40 to be torsionally rotated by the rotational force of the power source. According to an embodiment of the present invention, the power source is composed of a motor 54 capable of driving forward and backward and a manual knob 57 which rotates by a human hand, so that the flexible rotary shaft may be selected from the motor 54 and the manual knob 57. One end of 40) can be torsionally rotated.

2, the rotation means 50 includes a motor 54 capable of forward and reverse operation; A manual knob 57 vertically rotatably arranged so that a person can rotate by hand; A shaft 51 rotatably vertically arranged; A main gear 52 fixed to the lower end of the shaft 51; A driven gear 53 meshed with the main gear 52 to rotate by the main gear 52 and fixing one end of the flexible rotation shaft 40 to the rotation shaft; A first clutch (55) for selectively transmitting the rotational force of the motor (54) to the shaft (51); A second clutch 56 installed at an upper end of the shaft 51 to selectively transmit the rotational force of the manual knob 57 to the shaft 51; And a rotation sensor 59 for detecting the rotation speed of the shaft 51. .

According to the embodiment of the present invention, since the rotation shaft of the motor is horizontal and the first clutch 55 is installed at the end of the rotation shaft of the motor, the rotation shaft intermittent to the first clutch 55 is also placed horizontally, so that the first clutch The rotational force of the motor intermittent at 55 was transmitted to the shaft 51 by the bevel gears 58 and 58 '. If the axis of rotation of the motor is vertical, it is possible to transfer the rotational force to the shaft 51 using a spur gear. In addition, a speed reducer (not shown) may be installed between the motor 54 and the first clutch 55 to transmit power through the first clutch 55 at a rotational speed lower than that of the motor 54. Can be.

Here, the motor 54 is controlled by a controller 60 to be described later to start / stop and reverse rotation. The first clutch 55 and the second clutch 56 are controlled by the controller 60, which will be described later, to be in a power transmission state or a power transmission interruption state. For example, the first clutch 55 and the second clutch 56 are electromagnetic clutches that operate according to an interruption of electricity supply. Can be configured. The rotation speed information of the shaft 51 sensed by the rotation sensor 59 is transmitted to the controller 60.

The rotating means 50 is configured to intermittent the rotational force transmission of the motor 54 to the first clutch 55, and the rotational force transmission of the manual knob 57 to the second clutch 56, so The clutch 55 and the second clutch 56 are controlled to transmit the rotational force of any one of the motor 54 and the manual knob 57 to the shaft 51. As a result, the rotation of the driven gear 53 engaged with the main gear 52 fixed to the shaft, that is, the torsional rotation of the flexible rotation shaft 40 is caused by the operation of the first clutch 55 and the second clutch 56. It is made by the rotation of the motor 54 or the manual knob 57.

On the other hand, according to the embodiment of the present invention, a plurality of driven gear 53 is rotated by being engaged with the main gear 53 is provided along the outer peripheral surface of the main gear 53, each of the driven gear 53 One end of the flexible rotating shaft 40 can be fixed. Accordingly, the flexible rotary shafts 40 are installed in accordance with the number of the valves 20 respectively provided in the plurality of discharge ports 2 formed in the four dams, and the ends of the flexible rotary shafts 40 are one-to-one with the plurality of driven gears ( By fixing to 53, the rotating means 50 can open and close the plurality of valves 20 at the same time.

The reducer 30 is a component installed in the valve 20, the other end of the flexible rotary shaft 40 is rotatably laid (rotating rotatably fixed to the rotary shaft of the first gear to be described later), the flexible The valve 20 is opened and closed by changing to a rotational force of a rotational speed lower than the rotational speed of the rotational shaft 40. Referring to the drawings illustrated in FIG. 2, the valve 20 is opened and closed by the spindle 21 protruding upward and forward and reverse rotation of the spindle 21, and at the end of the spindle 21. The first gears meshed with each other by making the diameter (or pitch circle) of the second gear 32 fixed smaller than the diameter of the first gear 31 which fixed the other end of the flexible rotary shaft 40 to the rotary shaft. And the rotation speed of the second gear 32 is smaller than the rotation speed of the first gear 31 in accordance with the gear ratio of the second gear.

As the deceleration of the rotational speed by the reducer 30 increases the torque, the flexible rotating shaft 40 opens and closes the valve 20 with a high torque even when the flexible rotating shaft 40 rotates at a low torque (rotation by the rotating means). can do.

That is, the flexible rotary shaft 40 is long wired between the rotating means 50 and the reducer 30. If the flexible rotary shaft 40 is rotated with excessively high torque, the flexible rotary shaft 40 may be damaged. When rotating below the torque allowed by the material of 40, and opening / closing the valve 20, it is good to convert into high torque using the reducer 30.

On the other hand, referring to Figure 2, the gears provided in the reducer 30, and the shaft, the gear, the clutch and the component provided in the rotating means 50 is required for the component to rotatably support, such a It is to be noted that the supporting component is not shown in FIG. 2 because it is natural to those skilled in the art.

As shown in FIG. 3, the controller 60 is connected to a remote controller 10 installed remotely through a communication network to receive a command of the remote controller 10 to control the motor 54 of the remote controller 10. A communication unit 65 for controlling driving / stopping and reverse rotation, a power supply unit 66 for supplying electricity, a switch 62 for selecting a manual mode for opening and closing a valve by rotating the manual knob 57, and Motor control unit 63 for starting / stopping and forward / reverse rotation of motor 54, and clutch control unit 64 for converting the first clutch 55 and second clutch 56 into a power transmission state and a power transmission blocking state. And a controller 61 for controlling the overall operation of the controller 60.

As shown in FIG. 3, a camera 67 for video surveillance and a water level sensor 68 for measuring the water level may also be included, but such a configuration may be generally employed, and the power supply 66 may be externally supplied. In the case where it is not supplied, it can be generally configured as a solar cell or a wind power generator as shown in Figure 1, the description of the power supply 66, the camera 67 and the water level sensor 68 will be omitted.

As for the control part 61 of the controller 60 comprised as mentioned above, the rotation speed (or rotation angle) of the said shaft 51 required for opening and closing of the valve 20 is preset previously. That is, the valve 20 is opened and closed by rotating the spindle 21 exposed to the upper portion of the valve 20 body, the rotation angle of the spindle 21 required for opening and closing the valve 20 is the reduction ratio of the reducer 30 ( In the example of FIG. 2, the rotational speed of the shaft 51 (or the gear ratio between the first gear and the second gear) and the gear ratio between the main gear 52 and the driven gear 53 in the rotating means 51 Rotation angle). Accordingly, the rotation speed (or rotation angle) of the shaft 51 required for opening and closing the valve 20 may be preset, and the preset rotation speed is stored in a memory (not shown) of the controller 61. It is used when opening and closing the valve 20 in accordance with the command of the remote controller 10 or the operation of the switch 62.

The control unit 61 leaves the first clutch 55 and the second clutch 56 in the power transmission cutoff state without the command of the remote controller 10 and without the operation of the switch 62. Of course, the motor 54 is also stopped. In this state, transmission of power by the second clutch 56 is interrupted, and therefore, even if the manual knob 57 is turned, it is lost.

Subsequently, when a command reception of the remote controller 10 or an operation of the switch 62 occurs, an operation distinguished from the following is performed.

When the command of the remote controller 10 is received, the shaft 54 is rotated by the rotational force of the motor 54 while the motor 54 is operated and the first clutch 55 is switched to the power transmission state. Accordingly, the rotation of the main gear 52 fixed to the shaft 51, the rotation of the driven gear 53, the torsional rotation of the flexible rotary shaft 40, and the deceleration rotation of the reducer 30 are sequentially transmitted to the valve ( 20) Open and close. If the command of the remote controller 10 is to open, the motor 54 is rotated forward to open the previous closing state, and if the command of the remote controller 10 is to close, the motor to close the previous opening state. Reverse (55). At this time, the controller 60 detects the rotational speed (or rotational angle) of the shaft 51 with the rotation sensor 59 so that when the preset rotational speed is reached, the controller 60 switches the first clutch 55 to the power transmission cutoff state. The rotation of the shaft 51 is stopped. Of course, the motor 54 is also stopped.

Since the operation of the switch 62 is a manual mode, the second clutch 56 is switched to a power transmission state, and the shaft 51 can be rotated by the rotation of the manual knob 57. In this case, the controller 60 may detect the rotational speed (or rotational angle) of the shaft 51 with the rotation sensor 59, and thus, when the preset rotational speed is reached, the second clutch 56 may be cut off. The rotation of the manual knob 57 prevents the shaft 51 from rotating. Of course, since the shaft 51 is rotated forward or reversely according to the rotational direction of the manual knob 57, the valve can be opened and closed. In this case, the controller 60 may include a lamp indicating whether the valve is in an open state or a closed state. Accordingly, the controller 60 may determine the rotation direction of the manual knob 57 after recognizing the open / closed state of the valve.

Here, in the situation where the command of the remote controller 10 is received or in the manual mode by the operation of the switch 62, the manual knob 57 can be rotated by a shaft that rotates with the rotational force of the motor. Since the user who wants to hold the manual knob 57 may be injured, it is preferable to control the command of the remote controller 10 in preference to the manual mode.

That is, when the shaft 51 is rotated by the rotational force of the motor 54 according to the command of the remote controller 10, the second clutch 56 is maintained in the power transmission interruption state even if the operation of the switch 62 occurs. The manual knob 57 is prevented from being rotated by the rotational force of the shaft 51. Moreover, the four sides of the dam, for example, hikers may come in and operate the switch 62 to turn the manual knob 57 may occur, and the manual knob 57 may turn to a joke, so for safety When opening and closing the valve according to the command of the controller 10, it is desirable to block the power transmission between the manual knob 57 and the shaft 51.

On the other hand, if the switch 62 is mounted inside the panel on which the lock device is installed, and the lock device can be operated after the lock device is opened, the above-described risk can be prevented, and thus, the priority of the switch 62 is not required. However, for the sake of safety, it is better to give priority to the command of the remote controller 10 as described above.

In addition, the switch 62 may further include a motor driving switch for opening and closing the valve by the operation of the motor 54 instead of the manual knob 57. That is, the operation of the motor drive switch is to open and close the valve by the rotational force of the motor by controlling the motor and the first clutch as instructed by the remote controller 10. Here, it is preferable to open and close the valve by giving the command of the remote controller 10 over the operation of the motor drive switch.
