Description

{Water Draining System of Siphon Type}

The present invention relates to a siphon-type drainage apparatus, and more particularly to a siphon-type drainage apparatus capable of discharging water collected in a primary water tank such as a manhole or water in a reservoir or dam using a siphon principle, ≪ / RTI >

Generally, subway or railway facilities store ground water from the retaining wall around the track and underground water leaking out from the underground pipe to the primary water tank, which is primarily called a manhole, and transfer the water stored in the primary water tank to the water collection tank And then draining the effluent to the outside by discharging it to the outside.

Such a conventional effluent drainage system is a structure in which the effluent of a manhole as a primary storage tank is transferred to a secondary storage tank by a pump. Therefore, when the effluent gradually flows into the manhole, the water in the manhole can be smoothly transferred to the secondary water tank through the pump. However, when the heavy rain occurs in a short time, the rate of water in the manhole flows out to the secondary water tank through the pump The water overflows out of the manhole, causing problems such as inundation of lines and facilities.

To solve such a problem, a siphon type subway groundwater conveyance device is disclosed in Japanese Patent No. 0348526 in which water in a manhole can be forcibly discharged using a siphon principle by a secondary water tank. In the siphon type subway groundwater conveyance device of the above-mentioned patent, one end of the main siphon pipe (discharge pipe) is immersed in a water reservoir and the other end is extended outward to the outside of the water reservoir to be bent downward, one end of the siphon- And the air discharge pipe is connected to the main siphon pipe at a horizontal portion adjacent to the discharge portion of the main siphon pipe and connected to the arc-shaped storage pipe at the end of the main siphon pipe, The air in the pipe is discharged to the outside through the discharge pipe to cause a sudden pressure reduction in the main siphon pipe so that the water can be forcedly discharged through the main siphon pipe.

In addition, Korean Patent No. 0644356 allows the water of the reservoir to be drained so that the water level of the bank or the reservoir can be adjusted to the highest water level, the normal water level and the lowest water level, so that the water can be effectively used. There is disclosed a siphon ferry which is capable of controlling the amount of displacement by a multistage water level capable of smoothly controlling the flood.

However, the siphon-type subway groundwater transfer device and the siphon fossil of the above-mentioned patent must be constructed by connecting a siphon-induced pipe and an air discharge pipe or a water level control pipe to the outside of the water inflow portion and the discharge portion, , There are places where construction is not possible depending on the place, and there is a problem that the manufacturing cost is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a syringe which can be moved to a desired place by operating a siphon in a short time through an induction pipe vertically installed in a tube with a small amount of water, It is possible to discharge a large amount of water in a short time and to remove the components such as the siphon-inducing pipe, the pressure equalizing pipe, the air discharge pipe, and the blocking part, which were constructed in the conventional siphon type drainage device (for example, patent No. 0348526) Thereby simplifying the structure, facilitating the construction, and reducing the manufacturing cost.

To achieve the above object, a siphon type drainage apparatus according to the present invention is characterized in that a siphon type drainage apparatus is disposed at an inner side of a water storage tank where one end portion stores water and is extended to a place where another end portion is intended to discharge water, A discharge pipe having a connection pipe formed in an up-down direction and a vertical direction; A U-shaped bent reservoir tube having one end connected to the lower end of the connecting pipe; And an inlet port through which the water flowing through the connection pipe is formed is formed at an upper end portion of the connection pipe so as to have a diameter smaller than the diameter of the connection pipe, And a siphon-evacuating tube having an inclined outlet inclined toward the central portion.

According to the present invention, since the siphon-induced pipe for causing the siphon phenomenon is formed inside the discharge pipe, the structure is greatly simplified compared with the conventional siphon type drainage device, the structure is not affected by the structure, .

In addition, since the slope outlet at the bottom of the siphon-inducing tube is inclined at an angle to the vertical axis, water discharged through the sloping outlet hits the upper portion of the curved portion of the arc- Can be promptly and surely induced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a siphon-type drainage apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 illustrate a siphon-type drainage device for discharging water collected in a water tank such as a manhole of a subway facility to a regional water tank of a subway.

1 to 3, a siphon-type water drainage apparatus according to an embodiment of the present invention includes a primary water tank 10 for collecting water, a water tank 2 for collecting water conveyed from the primary water tank 10, A water tank 20 extending from an inner side of the primary water tank 10 to an upper side of one side of the secondary water tank 20 to deliver water from the primary water tank 10 to the secondary water tank 20, A U-shaped curved storage pipe 40 connected to the lower end of the discharge pipe 30 in the secondary water storage tank 20 and a discharge pipe 30 extending in the vertical direction inside the discharge pipe 30, And a siphon-inducing tube 50 installed to induce a siphon phenomenon.

The primary water storage tank 10 is a manhole installed in a railroad facility such as a subway and the secondary water storage tank 20 is a regional water storage tank of the subway. The storm water is introduced into the manhole, which is the primary water storage tank 10, The stormwater is transferred to the secondary water tank 20 through the discharge pipe 30 and stored therein and the stormwater stored in the secondary water tank 20 is discharged to the outside by the pump 60 installed in the secondary water tank 20 .

The secondary water tank 20 is installed at a lower height than the primary water tank 10. One end of the discharge pipe 30 located inside the primary storage tank 10 is disposed at a higher position than the end of the arc-shaped storage pipe 40. Therefore, when the rainwater flows into the primary water tank 10 and reaches a certain water level, the water in the primary water tank 10 flows into the secondary water tank 20 through the discharge pipe 30 due to the water head difference.

One end of the discharge pipe 30 is disposed inside the primary water tank 10 and the other end is extended toward the secondary water tank 20. A portion of the discharge pipe 30 installed in the secondary water tank 20 is connected to the secondary water tank 20 And a connection pipe (32) vertically and vertically extending inwardly. The arc-shaped storage pipe (40) is connected to the lower end of the connection pipe (32).

The exhaust pipe 30 is provided with an exhaust valve 33 for exhausting air to the outside.

As shown in FIGS. 2 and 3, the connection pipe 32 of the discharge pipe 30 is installed vertically upside and downside the inside of the secondary water tank 20. A U-shaped curved arch pipe 40 is connected to the lower end of the connecting pipe 32.

The siphon-inducing pipe 50 is formed in a circular tube shape having an upper end and a lower end opened and having a diameter smaller than the diameter of the connecting pipe 32. The siphon-inducing pipe 50 is installed inside the connecting pipe 32 to extend vertically, . An inlet 51 is formed at an upper end of the siphon-inducing pipe 50 and an inclined outlet 52 is formed at a lower end of the siphon-inducing pipe 50. The inclined outlet 52 is inclined toward the center of the arc- A guide portion 53 is formed in the inlet port 51 at the upper end of the siphon-inducing pipe 50 so as to extend to both sides of the siphon-inducing pipe 50 in order to initially introduce the water flowing into the connection pipe 32 into the siphon- . The guide part 53 guides water flowing sideways of the inlet port 51 toward the inlet port 51 through the discharge pipe 30 toward the inside of the connection pipe 32, So that it can flow into the pipe 50.

The inclined outlet 52 of the siphon tube 50 is inclined at a predetermined angle with respect to the axis of the siphon tube 50 so as to be inclined at an angle of for example 45 degrees, So that the water discharged through the outlet 52 can be discharged toward the center of the arc-shaped storage tube 40.

The siphon tube 50 may be integrally formed on the inner surface of the coupling tube 32. Alternatively, the siphon tube 50 may be formed integrally with the coupling tube 32 and then connected to the inner surface of the coupling tube 32 by a separate fastening means Or may be fixedly installed.

The water flowing into the secondary water tank 20 through the discharge pipe 30 flows into the siphon-inducing pipe 50 through the inlet 51 of the siphon-inducing pipe 50 and then flows into the siphon- It falls down. The water dropped along the siphon-inducing pipe 50 is discharged at a high speed toward the upper end of the center of the arc-shaped storage pipe 40 by the inclined outlet 52 at the lower end of the siphon-inducing pipe 50 together with the air.

The water and air discharged through the inclined outlet 52 of the siphon-inducing pipe 50 are struck on the upper side of the center of the water in the arc-shaped storage pipe 40. In this portion, the water- And air and water are discharged through the curved central portion of the arc-shaped reservoir tube 40. As a result, the amount of air in the discharge pipe 30 is reduced so that the pressure in the pipe is drastically lowered. By the siphon principle, water in the primary water tank 10 is rapidly sucked into the discharge pipe 30 and flows through the entire cross- And then sent to the secondary water tank 20.

Accordingly, since the water in the primary water tank 10 can be transferred to the secondary water tank 20 at a high speed, the water head difference at the time of heavy rain rises and more water can be transferred quickly, . The water transferred to and stored in the secondary water tank 20 is discharged to the outside by the pump 60 and processed.

As described above, according to the present invention, since the siphon-inducing pipe 50 for causing the siphon phenomenon is integrally formed inside the connection pipe 32 of the discharge pipe 30, the structure is greatly simplified compared to the conventional siphon- , And is easy to construct and manufacture. The siphon operation can not be easily performed without the siphon induction pipe 50. However, the present invention is not limited to the siphon induction pipe 50 provided in the vertical connection pipe 32, And an easy siphon inducing action can be performed.

The inclined outlet 52 at the lower end of the siphon inducing pipe 50 is inclined at a predetermined angle with respect to the vertical axis so that the water discharged through the inclined outlet 52 strikes the vicinity of the curved part center of the arc- The bubbles are generated, so that the air can be discharged quickly, so that the siphon phenomenon can be promptly and surely induced.

The siphon-type drainage apparatus of the present invention is a drainage apparatus for transferring groundwater, which transfers the water of the primary storage tank 10, such as a manhole of a railway facility, to a secondary storage tank 20 such as a water tank in a subway station, In addition, the siphon-type water drainage apparatus of the present invention can be applied to a siphon waterway which discharges water stored in a dam or a reservoir to the outside or discharges it to a designated place.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
