Figure 3 is a hydraulic circuit diagram showing another embodiment of the hydraulic drive unit for opening and closing the water gate.

The present invention relates to a water gate opening and closing device, and more particularly to a water gate opening and closing device for improving the safety device for opening and closing the water gate.

In general, water gates are installed in dams, reservoir embankments, and embankments in rivers or rivers, and water gates are installed to trap or discharge water. Most of the gates are installed by manual, semi-automatic, and automatic switching devices.

The switchgear of such a gate is electric and hydraulic. For example, the electric type of wire rope hoist type using a motor is expensive and large in size compared to the lifting capacity, thus providing a relatively large installation area, high installation cost, and high noise. In particular, relatively high maintenance and maintenance costs are required.

Utility Model Registration No. 0329971 discloses an up and down hydraulic door using a wire. The disclosed hydraulic sluice has a structure for transferring the rod lifting force of the hydraulic cylinder to the sluice using a rope. The hydraulic hydrogate opening and closing device disclosed in Utility Model Registration No. 0171459 is made by operating a hydraulic cylinder to which a hydro gate and a rod are connected by using hydraulic oil transferred from an oil rock pump.

On the other hand, registered utility model No. 0332997 discloses a hydraulic gate opening and closing device. The disclosed hydraulic gate opening and closing device is provided with a water level control container for adjusting a set water level, a manual operation room having an oil tank, and an operation handle for operating a manual hydraulic jack installed in the manual operation room.

Conventional water gate opening and closing device configured as described above can not block the inflow of birds when the operation of the hydraulic pump supplied to the hydraulic cylinder can not be opened and closed, as a result there is a risk of large accidents.

In addition, Utility Model Application No. 2003-15265 has been disclosed. Since the disclosed hydrogate is lifted and lowered by two hydraulic cylinders installed on both the left and right sides of the door frame, the number of hydraulic cylinders is also doubled according to the number of the gates. It is difficult to manufacture and install, and the installation cost is increased, as well as maintenance is not easy because any one of the hydraulic cylinder failure is not possible to operate the gate.

 The water gate disclosed in Korean Utility Model Application No. 2003-22220 installs a single hydraulic cylinder which is connected to an electric hydraulic generator and installs wire rollers on both the left and right sides of the water gate, so that both ends of the door roller It has a fixed installation on it. As described above, the hydrological opening and closing device using hydraulic pressure cannot fundamentally solve the problems as described above because the hydrological gate cannot be operated when the hydraulic pump is stopped.

The present invention is to solve the problems as described above, an object of the present invention is to provide a water gate opening and closing device that can block the flow of water by operating the water gate by its own weight when the operation of the hydraulic pump due to power outages.

Another object of the present invention to prevent a safety accident according to the operation of the hydraulic motor, to provide a water gate opening and closing device that can be individually blocked of the plurality of gates.

Still another object of the present invention is to provide a water gate opening and closing device that can be relatively simple in structure and easy to install, thereby improving productivity and reducing maintenance costs.

Referring to the drawings, the hydrological opening and closing device 10 is installed in the dam 111, the return of the reservoir, the dike, etc. to open and close the water gate 112, the dam is installed on the dam or adjacent to the upper portion of the water gate 112 ( 111a, a drum 114 rotatably installed on the frame 111a and a rope 113 for lifting the water gate 112, and a drum 114 mounted on the frame 111a to fix the drum 114. And, winch means 110 including a hydraulic motor 115 to reverse rotation, and a hydraulic drive unit 120 for forward and reverse rotation of the hydraulic motor 115 is provided. Here, the reduction gear unit 116 may be further provided between the rotating shaft of the hydraulic motor 115 and the drum 114.

The hydraulic drive unit 120 is to rotate the hydraulic motor 115, 115, 115 forward and reverse, an embodiment thereof is shown in Figs.

Referring to the drawings, the hydraulic drive unit 120 is a hydraulic motor 115, 115, 115 for driving the drum 114 and a hydraulic pump 122 for pumping hydraulic oil from the hydraulic tank 121. And first, second and third installations in the pipeline 123 connecting the hydraulic pump 122 and the hydraulic motor 115 to control the supply of hydraulic oil to the hydraulic motors 115, 115 and 115. Control valves (124) (125) (126). Here, the first, second, third, and control valves 124, 125, and 126 use a four-port three-position control valve, and the hydraulic motors 115, 115, and 115 are rotated forward and stop. It is desirable to be able to control it.

Meanwhile, a relief valve 127 for returning hydraulic oil to the tank 121 at a predetermined pressure may be provided in a conduit between the first, second, and third control valves 124, 125, 126 and the hydraulic pump 122. The check valve 128 may be installed.

Meanwhile, the hydraulic pump is disposed in the first and second pipelines 131 and 132 between the first, second, and third control valves 124, 125, 126 and the hydraulic motors 115, 115, and 115. Or bypass means 130 for blocking the water gate by driving the hydraulic motor when the operation of the control valve is further provided. The bypass means 130 is branched from the first and second pipelines 131 and 132 to form the first and second branch engines 133 and 134 connected to the tank 121. First and second valves 135 and 136 are installed in the two branch pipes 133 and 134, respectively, and at least one side of the first and second branch pipes 133 and 134 controls the flow of hydraulic oil. 137 is installed. The bypass means 130 is not limited to the above-described embodiment, and the drum 114 is rotated by the weight of the water gate in the state where the hydraulic oil is not supplied from the hydraulic pump 122 to thereby operate the hydraulic motor 115. Any structure can be used as long as it can rotate.

For example, as shown in FIG. 3, a connecting pipe 139 is installed between the first and second pipe lines 131 and 132, and the third valve 140 and the orifice 141 are installed in the connecting pipe 139. May be installed and made.

And a control unit 300 for driving the hydraulic driving unit 120. The control unit 300 further includes a control panel although not shown in the drawing, and the signal is not detected for a set time after the operation. In this case, the system may further include means for generating an alarm light and a warning sound indicating an operational error state.

Reference numeral 400 is a two-port, two-position control valve that controls the hydraulic oil supply from the hydraulic pump 122 to the first, second, and third control valves 124, 125, and 126.

In order to open and close the water gate 112 by using the water gate opening and closing device 10 according to the present invention configured as described above by operating the hydraulic pump 122 using the control unit 300 and the first of the water gate to be opened The control valve 124 is operated to drive the hydraulic motor 115.

In this case, the first control valve 124 is operated by the controller 300, and hydraulic oil is supplied to the hydraulic motor 115 to rotate the drum 114 to open the water gate. By adjusting the second and third control valves 125 and 126, the water gate 112 may be selectively opened as described above.

In this state, when the hydraulic oil cannot be supplied to the hydraulic pump due to a power failure or a failure of the hydraulic pump or the control valve, and the water gate needs to be closed rapidly, the first branch pipe 133 of the bypass means 130 is installed. The second valve 136 installed in the first valve 135 and the second branch pipe 134 is opened. In this way, the drum 114 is rotated by the weight of the water gate, and the hydraulic oil is rotated while being returned to the tank through the first branch pipe 132 to close the water gate. In this process, since the orifice 137 is installed in the first branch pipe 132, the flow of hydraulic oil is gentle, so that the floodgate 112 is rapidly closed, thereby preventing the floodgate on the floodgate.

Meanwhile, as shown in FIG. 3, when the connecting pipe 139 is installed between the first and second pipes, the first and second pipes and the connecting pipe are opened by opening the third valve 140 installed in the connecting pipe 139. 139 and the hydraulic motor 115 forms a closed circuit to allow hydraulic oil to flow, thereby driving the hydraulic motor by the weight of the hydrologic gate to close the hydrologic gate. Therefore, even if a power failure, a hydraulic motor, a control valve, or the like occurs, a safety accident can be prevented by closing the gate as described above.

As described above, the switchgear of the water gate according to the present invention can reduce the generation of noise and reduce the size by using a hydraulic motor, thereby reducing the production cost due to its manufacture, and promoting safety by closing the floodgate in an emergency. Has the advantage to do that.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.
