The valve cylinder 20, which is opened downward, is inserted into the elevating space 15 to be in close contact with the inner surface of the valve body 10, and water may also flow into the elevating space 15 of the valve cylinder 20. The inflow hole 21 is formed to communicate with each other at the same position as the inflow hole 17.

When the through hole 14 is closed by the opening and closing member 70 ', the seat 30 is placed on the upper portion of the inner jaw 13 so that water does not leak between the opening and closing member 70' and the inner jaw 13. At this time, the gasket 40 is provided on the seat 30 to increase the sealing effect.

In this case, the seat 30 and the gasket 40 are preferably positioned on the inner jaw 13 under the inflow holes 17 and 21 so as not to be pushed out through the inflow holes 17 and 21.

The buoy 50 that is elevated along the valve cylinder 20 in accordance with the water level in the lifting space 15 is connected at a predetermined distance by the opening and closing member 70 ′ and the link 60 at the lower portion of the buoy 50.

That is, if the distance between the buoy 50 and the opening / closing member 70 'is short, the water level for opening the through hole 14 is low, and if the distance is long, the water level for opening the through hole 14 is high.

When the buoy 50 is lowered as the water level inside the sump 1 is lowered, the opening / closing member 70 ′ is lowered together with the buoy 50 to be in close contact with the seat 30, that is, between the inner jaws 13. When the buoy 50 rises as the water level increases, the through hole 14 is sealed to prevent the water from being discharged to the outside. As the buoy 50 rises together with the buoy 50, the through hole 14 is spaced apart from the seat 30. Open to allow the water in the sump 1 to be discharged.

The opening and closing member 70 'is smoothly lifted and lowered along the valve cylinder 20 so that the left and right widths of the opening and closing member 70' are prevented from leaking between the opening and closing member 70 'and the valve cylinder 20. It is formed a little larger than the inner width of the), the opening and closing member 70 'is preferably made of a rubber material and the like.

In addition, the pinhole 71 is vertically positioned on the opening / closing member 70 'of the upper side of the inner jaw 13 to reduce the pressure difference between the hydraulic pressure of the upper opening / closing member 70' and the lower atmospheric pressure. A large number is formed through the through.

At this time, the thickness or number of the pinholes 71 can be variously changed according to the water pressure or the capacity of the sump (1).

Water penetrates slightly between the opening and closing member 70 ′ and the gasket 40 through the pinhole 71 to facilitate opening of the through hole 14 by hydraulic pressure.

In addition, the opening and closing member 70 'or the buoy 50 may be changed in various shapes according to its capacity as well as a circular shape as shown in FIG. 6, and the pinhole 71 in the rectangular opening and closing member 70'. ) Can be formed.

The open upper and lower portions of the vertical tube 11 are closed by the cover 80 so that water does not enter through the upper and lower portions, and the open side of the horizontal tube 12 is coupled to the flange 82 to the outside. It is connected to the drain pipe (3).

In the second embodiment, the oil detection device 90 for detecting the presence or absence of oil and the thickness of the oil is further provided. As shown in FIG. 5, the oil detection device 90 includes a battery 91 and a microcomputer 92. ), An antenna 93, and an A / D converter 94.

Here, for example, the oil detecting device 90 is embedded in another buoy 50 ', and the height and the height are adjusted together with the water level to detect the presence or absence of oil floating on the water and the thickness of the oil.

The battery 91 supplies power to the microcomputer 92, and the microcomputer 92 generates a high frequency wave (microwave) to propagate high frequency to the surroundings through the antenna 93, and reflects the high frequency incoming through the antenna 93. It detects the presence of oil floating on the water and the thickness of oil at the reception rate of.

For example, if there is no oil floating on the water surface, the electromagnetic wave shows a reception rate close to 100% in the antenna 93, and when there is oil floating on the water surface, the reception rate of the electromagnetic wave received by the antenna 93 is proportional to the thickness of the oil. Decreases.

Finally, the electromagnetic wave received by the antenna 93 is converted into a current through the A / D converter 94, and the microcomputer 92 detects the oil thickness floating on the water surface according to the intensity of the current. Larger means thicker oil.

If the thickness of the oil is greater than or equal to the reference thickness, the microcomputer 92 may remove the oil by notifying the user of the monitoring system by transmitting that the thickness of the oil is greater than or equal to the reference thickness to the monitoring system installed in a separate place through the antenna 93. Make sure

Looking at the operating state of the sump device having the above configuration, as shown in Figure 3, when the water level is reduced to a certain level or less, the buoy 50 is lowered in the valve cylinder 20 to the buoy 50, The opening / closing member 70 connected to the link 60 is also lowered in the valve cylinder 20 and then stopped by being seated on the seat 30 on the upper side of the inner jaw 13.

As a result, the upper portion of the through hole 14 is blocked by the opening and closing member 70 ', and soaks into and flows out between the opening and closing member and the seat 30 through the pinhole 71 formed in the opening and closing member 70' to reduce the pressure difference. , The amount of water flowing out is very small, the maximum height (H) of the inlet holes (17, 21) is located below the water level when the through-hole 14 is closed, the hard oil floating on the water is inlet (17, 21) It is essentially prevented from entering the lifting space (15) through.

In addition, as shown in FIG. 4, when external water flows into the sump 1 due to rain or the like, as the water level increases, the buoy 50 also rises along the valve cylinder 20 and links to the buoy 50 ( The opening / closing member 70 connected to 60 also rises inside the valve cylinder 20 and is spaced apart from the seat 30.

As a result, the water in the sump 1 is discharged to the surrounding drain pipe 3 through the valve body 10 while the inner jaw 13, that is, the through hole 14 is opened.

At this time, the minimum height (h) of the inlet holes (17, 21) formed in the valve body 10 is formed higher than the bottom surface of the sump (1) so that the heavy oil that has sunk on the bottom surface through the valve body (10) It does not leak to (3).

On the other hand, the microcomputer 92 of the oil detection device 90 embedded in the buoy 50 'is the presence of oil floating on the water surface and the thickness of the oil at the reception rate of the high frequency propagating and returning through the antenna 93 Detect.

As the sump device shown in FIGS. 3 and 4 is repeatedly operated, oil is not discharged to the outside and accumulated on the surface of the water. At this time, when the thickness of the oil is greater than the reference thickness, the microcomputer 92 transmits the fact to an external monitoring system. To inform the user of the monitoring system that a lot of oil has flowed into the sump (1).

That is, the through-hole 114 is blocked by the opening and closing member 170, the opening and closing member 170 is in surface contact with the inner jaw 113 by the gasket 140 so that water does not seep between the valve body 110 Water or oil (including light oil (4), heavy oil (5)) is no longer discharged to the surrounding drain pipe (3).

At this time, the maximum height (H) of the inlet hole 117 is formed below the water level when the through-hole 114 is closed so that the hard oil floating on the water flows into the lifting space 115 through the inlet hole 117. Is essentially prevented.

In addition, as shown in FIG. 8, when external water flows into the sump 1 due to rain or the like, as the water level increases, the buoy 150 also rises along the lifting space 115 and links to the buoy 150 ( The opening and closing member 170 connected at one side to 160 is rotated clockwise to be spaced apart from the inner jaw 113.

As a result, the water inside the sump 1 is discharged to the surrounding drain pipe 3 through the valve body 110 while the inner jaw 113, that is, the through hole 114 is opened.

At this time, the minimum height (h) of the inlet hole 117 formed in the valve body 110 is formed higher than the bottom surface of the sump (1) so that the heavy oil (5) that sank to the bottom surface through the valve body 110 It does not flow out to the drain pipe 3.

In the third embodiment, the buoy 150 is connected to one side of the opening / closing member 170 which rotates around the pivotal shaft 171 in the center, and is connected to the link 160 so that the buoy 150 opens and closes when the buoy 150 is raised. Since one side of the member 170 is rotated counterclockwise to be spaced apart from the inner jaw 113, the through hole 114 may be opened under the influence of hydraulic pressure.

Various embodiments of the sump device as described above may be installed in a waterway, such as an agricultural waterway, to be applied to control a water gate.
