Description

Non-powered conduction sluice {WATERGATE}

The present invention relates to a sluice, and more particularly, when a flood is expected due to an increase in river water, an electric power supply conduction capable of releasing fresh water by normally opening the sluice even if the electric device, which is the driving source of the sluice, does not operate due to a power failure or a failure. It's about sluice.

In general, aqueducts, rivers and reservoirs are used for the purpose of storing a certain amount of water for proper use in farmland management or irrigation water. These channels are equipped with a hydrological device that opens and closes the water gate to manage water, that is, to store water in case of drought and to release it when there is a large amount of rain and water.

In such a hydrological device, a method of opening and closing the water gate by manpower by rotating the control handle and a method of hydraulically rotating the water gate using a cylinder or lifting the water gate are used.

The conventional hydraulic water gate is installed in the ditches of the dike to store or discharge water to control the low water amount, and is composed of a water gate, an operation tool for turning the water gate to turn, and a housing for accommodating the operation port.

The water gate is installed in the ditches of the embankment serves to store or discharge the water to control the amount of storage. These sluice gates are installed in the ditches of the embankment in such a way that the shafts protruding integrally from each of the lower sides of the two sides are pivotally penetrated through the fixing brackets fixed to the bottom. You can turn.

The actuating tool is a structural unit which is installed at both sides of the hydrologic gate to pivot the hydrologic gate. That is, the operation tool is composed of a connecting link fixedly installed on one side of the shaft, and a hydraulic cylinder connected to the other side of the connecting link and rotated from the bottom of the hydraulic link. This hydraulic cylinder is then operated by a motor.

The connecting link and the hydraulic cylinder are preferably installed in relation to each other such that the upper surface of the floodgate is flush with the upper surface of the housing to be described later when the floodgate is placed vertically from the floor, and the floodgate is inclined at a predetermined angle from the floor. Do.

As described above, most of the conventional hydraulic hydrogates use an external power source as their power source to open and close the hydrologic gate according to the water level of the waterway, since the external power is cut off during a sudden power failure caused by a natural disaster such as a typhoon or a flood. As the water gate could not be opened and closed, the water flow could not be adjusted. Moreover, in the event of a power outage caused by natural disasters, the floodwaters usually need to be opened at the right time due to a sudden increase in water quantity, but if the bad news of the power failure overlaps, the water supply for the waterway will fail completely.

Therefore, in recent years, a technique has been proposed to provide a manual valve in such a water gate to open the water gate by manpower even in an urgent situation such as power failure.

The hydraulic oil conveyed through the hydraulic pump is filled in the hydraulic cylinder via the solenoid valve. Therefore, the water gate is opened and closed according to the cylinder filling state of the hydraulic oil.

At this time, since the solenoid valve which is electrically operated in case of sudden power failure does not operate normally, in case of urgent opening of the water gate for the water level control, a person must go to the water gate to operate the emergency manual valve. You can open it. Therefore, if there is always a manpower around the water gate, watch the water level and suddenly increase the water level, manually operate the emergency manual valve, etc. to open the water gate to prevent accidents caused by rapid water increase. In fact, there is a lot of inconvenience and waste of manpower in such hydrological management. In addition, when a power outage and a sudden increase in water level occur at the same time, a natural disaster such as a typhoon or a flood is usually caused, and thus, it is true that the opening of the gate by manual operation through such manpower has many risks.

In addition, the fact that there is no means to open or close the gate even in the event of a sudden failure of the system controlling the gate, the fact that the most important water level control is dependent on manpower.

In order to solve this problem, a countermeasure device for controlling a water level has been proposed.

According to the conventional technology, when the water level of the river rises to the dangerous level, the floodgate is automatically opened by using the charging power to control the water level and the flow rate of the river, thereby preventing the flooding of water at the source, and in case of sudden power failure or system failure. Even if the river becomes dangerous level due to natural disaster such as typhoon or flood, it will automatically detect the danger level and open the gate by charging power without having to go to the water gate and operate the emergency manual valve. Therefore, there is an effect that it can automatically control the quantity of the streams stably without having to inject personnel into the floodgate in a dangerous situation, but the prior art also receives emergency power by operating the charging power. There is a big problem that can not work open.

In addition, the water level detection unit that detects the water level in the river detects the water level electrically, such as by using an electrode, and is installed in a fresh water state, so that water inflow occurs and malfunctions frequently occur. Therefore, the water gate is normally opened and closed. There is a problem that cannot be done.

The present invention is to solve the above problems, even when the water level of the river reaches the full water level and the power is not applied for the operation of the hydraulic cylinder to open and close the water gate to prevent the damage caused by flooding by opening the water gate normally In particular, it is an object of the present invention to provide a non-powered conduction flood gate that allows all series of operations such as river level detection and flood gate opening and closing operation to be operated without a power supply.

The non-powered conduction sluice gate according to the present invention for achieving the above object comprises: a valve actuating means for outputting a valve actuating signal when the water is suspended in the river water and reaches a predetermined level; It is installed in the main flow path for supplying fluid to the hydraulic cylinder for operating the opening and closing of the water gate, when receiving the valve operation signal from the valve operation means to recover the fluid supplied to the hydraulic cylinder through the main flow path to open the water gate A pilot check valve; It characterized in that it comprises a main valve for opening and closing the main flow path of the hydraulic cylinder.

According to the non-powered conduction sluice according to the present invention, when the power source, which is the driving source of the hydraulic cylinder for opening and closing the sluice, when the river level reaches a certain level, the fluid supplied to the hydraulic cylinder is recovered to allow the gate to be opened to flood the river water. Safety accidents can be prevented beforehand.

In addition, the water level can be detected even when the power source is disconnected by detecting the water level of the river water by the buoys floating in the river water, and inducing the opening action of the floodgate based on the detected water level. Since this is normally done, the river can be discharged and safety accidents caused by flooding can be prevented.

≪ Example 1 >

As shown in FIG. 1, the non-powered conduction sluice according to the present embodiment has a hydraulic motor for driving a hydraulic cylinder due to a power failure when the river water reaches a certain level (a water level that is expected to overflow as a full water level) during a power failure. It is possible to open the gate even without operation. In particular, the hydraulic cylinder flow path can be mechanically controlled to control the operation of the gate without using any power source such as a commercial power source or a battery storage battery.

First, the water gate is formed in a plate shape is installed in the channel of the dike to open and close the channel, the lower end is hinged to the dike, the conductive type to rise and rise while rotating through the hinge, can be vertically elevated to the dike channel Is installed so as to vertically open and close the waterway.

As shown in Figure 1, the present invention is a valve operating means for outputting the operation signal of the pilot check valve 20, the valve operating means when the water level of the stream upstream of the fresh water by the water gate 1 reaches the full water level Pilot check valve 20 for opening and closing the main flow path (2) for supplying fluid to the hydraulic cylinder (2) via the signal of (10) and main valve (30) for opening and closing the main flow path (2).

The valve operation means 10 outputs an operation signal of the pilot check valve 20 according to the water level of the river water, and outputs an operation signal of the pilot check valve 20 only when the water level is expected to overflow. That is, if there is not a large amount of fresh water, there is no need to open the waterway and at this time, even if a power failure occurs, the valve operation means 10 operates only at the water level at which the flood is expected, since the fresh water can heal the power failure before the flood level is expected. To output a signal.

The valve operating means 10 is a cylinder 11 into which the stream water flows in and out, a float 12 inserted into the cylinder 11 so as to be lifted and floating in the river water flowing into the cylinder 11, and the cylinder 11 and the pilot. In communication with the check valve 20 is made of an emergency line 13 to supply the fluid in the cylinder 11 to the pilot check valve 20 to operate the pilot check valve 20.

The cylinder 11 is formed in a cross-sectional area narrower than the first cylindrical portion 11a at the upper side of the first cylindrical portion 11a, the first cylindrical portion 11a into which the river water flows, and the fluid (oil) flows in and out of the second. It consists of the cylindrical part 11b.

The cylinder 11 of such a structure has a certain height (in connection with the water level at which flooding is expected) through fixing means (any structure capable of fixing the cylinder 11 is possible), such as a levee, which is a fixed structure in which the water gate 1 is installed. Fixed), and in this state, the lower portion of the first cylindrical portion 11a is opened so that the river water flows into the first cylindrical portion 11a.

The second cylindrical portion 11b communicates with the first cylindrical portion 11a on the upper portion of the first cylindrical portion 11a (which is communicated since the float 12 must be elevated) and is filled with oil.

The float 12 extends on the first rod 12a and the first rod 12a slidably inserted into the first cylinder portion 11a of the cylinder 11, and the second cylinder of the cylinder 11. The second rod 12b is slidably inserted into the portion 11b. Float 12 is raised or lowered by the river water flowing into the cylinder 11, the amount of river water is increased to increase the water level is raised and the oil filled in the second cylindrical portion (11b) by buoyancy at a constant pressure Pressurize and supply this hydraulic pressure to the pilot check valve 20. It will be apparent that the float 12 and the cylinder 11 are packed to prevent leakage of the river water and the oil, respectively. If the float 12 is raised and lowered sensitively to the change in the fresh water level, a malfunction of the pilot check valve 20 may occur, so the initial position of the float 12 is set to the level at which the flood is expected.

The emergency line 13 connects the second cylindrical portion 11b of the cylinder 11 and the pilot check valve 20 in fluid communication so as to guide the flow of oil as the float 12 moves up and down.

The pilot check valve 20 opens and closes the main flow path 2 by the normal operation of the hydraulic mechanism part (hydraulic motor 3, hydraulic pump 4, main valve 30, etc.) or correlates with the operation of the hydraulic mechanism part. Without opening the ball 21 to open the flow path to recover the oil supplied to the hydraulic cylinder (2) so that the water gate (1) is opened.

The pilot check valve 20 is a commercially available product is used and can be easily performed by connecting the main flow path 3 and the emergency line 13, respectively.

The main valve 30 is a solenoid valve, which receives an open / close signal and selectively connects a flow path to switch the flow of oil to control the open / close operation of the water gate 1.

The action of the non-powered conduction sluice according to the present invention configured as described above is as follows.

1. When the channel is closed

As shown in Figure 2, under the condition that the hydraulic mechanism is operating normally when the manual switch of the water gate closing switch is selected as the flow path of the main valve (30) as shown in Figure 3 by the pumping of the hydraulic pump (4) Passed through the pilot check valve 20 is supplied to the hydraulic cylinder (2), whereby the water gate (2) is raised while the rod (2a) of the hydraulic cylinder (2) is pulled out to close the waterway.

2. When opening the channel

As shown in FIG. 3, the flow path of the main valve 30 is switched so that the oil pumped by the hydraulic pump 4 opens the flow path by lifting the pilot check valve 20, and is supplied into the hydraulic cylinder 2 through the flow path. The extracted oil is recovered through the main flow passage 3 and the pilot check valve 20, and the rod 2a is inserted to invert the water gate 1 to open the water channel.

3. In case of flood

The main valve 30 normally maintains the state of FIG. 1, and the stream water flows into the cylinder 11 to have the same level inside and outside the cylinder 11, and when the level rises, the float 12 moves inside the cylinder 11. As a result, the oil in the second cylindrical portion 11b is supplied to the pilot check valve 20 through the emergency line 13.

As a result, the ball 21 of the pilot check valve 20 is raised to open the main flow passage 3, and the hydraulic cylinder 2 is not supported by the pressure of oil but is supported by oil filling. When the main flow path 3 is opened, oil is recovered to the tank 6 via the main flow path 3-the pilot check valve 20 by the weight of the water gate 2.

As a result, the water gate 2 is inclined to open the channel, so that the upstream river water is discharged downstream. In this process, no power is supplied and eventually the floodgate (1) can be opened at the water level where flooding is expected, even in the event of power failure, failure of the hydraulic motor (4), hydraulic pump (5), etc. Can be.
