Description

Rainwater reactor for prevent backwater

The present invention relates to a rainwater backflow prevention device, and more particularly, to prevent rainwater flowing back from the drains in which sewage and sewage are combined in a heavy rain or rainy season, so as to prevent flooding of lowland and basement houses. It relates to a rainwater backflow prevention device.

In general, sewage is joined to a larger sewage pipe through each small sewer pipe buried underground in each building, and is discharged to a river or sea area without being purified or discharged through a sewage treatment plant or the like, and discharged to the sewage treatment plant. The purified water purified through the above is used as industrial water by installing heavy water facilities as needed.

Further, in addition to the sewage discharged through the combined sewer pipes as described above, roads or sidewalks, etc., are provided with drains so that sewage, such as rainwater, can be discharged by being joined to each of the small sewage pipes or the large sewage pipes.

Therefore, in the process of discharging sewage and sewage through one sewage pipe as described above, in particular, a drain pipe having a size that allows the total amount of drainage to be discharged is buried in a drain hole of a portion where sewage and rainwater merge together. When this small or a certain amount of sewage was drained, it drained smoothly without major problems.

However, during the rainy season or during heavy rains during the summer season, a large amount of rainwater is instantaneously generated, so that the rainwater is not drained to the entire drainage point, but rather, the rainwater flows back from the confined drainage. It is located in a nearby area such as the sea or the sea, and low-lying zones and low-rise buildings, such as low-rise, caused a serious problem of flooding due to the reversed rainwater.

Due to such a problem, various devices, etc., which can block rainwater flowing back to the conventional sewers of each home, have been devised and used, and thus, many effects have been obtained.

In addition, as foreign materials are introduced through drain holes in drainage boards, sewage or rainwater flows back frequently due to sedimentation of manholes and reduction of sewage pipes during heavy rains.

However, as described above, the drainage port to which the sewage and rainwater join is not provided with the above-described backflow prevention device, and thus, the problem of flooding due to the backflow of the sewage or rainwater may not be solved.

Accordingly, the present invention has been made to solve the conventional problems as described above, the purpose is to prevent rainwater flowing back from the drainage drainage to the rainwater and rainwater to rainwater rainy season or rainy season, lowland and basement housing, etc. To prevent flooding.

The present invention for achieving the above object is the configuration of the present invention in the drain plate is formed with a plurality of drain holes are formed in the ground, and the drainage is installed in the drainage or rainwater drainage or confluence to the lower side in the conventional drainage, A plurality of guide grooves formed on an inner circumferential surface of the drain pipe; Foreign matter collection unit for preventing foreign matter (tobacco butts, garbage), etc. from the upper portion flows to the lower portion of the drain in the usual times into the sewage treatment plant; The upper surface is closed and the edge portion is protruded to form a blocking portion to block the drain hole of the drain plate, and the upper portion of the blocking portion is attached with a sealing ring made of a rubber material to completely prevent leakage to the upper portion during storm flow; A plurality of guide jaws and a plurality of discharge holes are formed to move up and down on the guide groove of the outer circumferential surface, and the lower end of the inner circumferential surface formed with the discharge hole is hinged and provided with a lifting member provided with an opening and closing plate to open and close the discharge hole. It is characterized by that.

The upper end of the guide jaw is characterized in that the locking jaw is integrally formed to be caught to the upper end of the guide groove is inserted.

In addition, the lower side of the inner circumferential surface on which the opening and closing plate is installed is characterized in that the support jaw is formed so that it can be supported with a predetermined slope in the open state.

A lowering member 5 is installed at a lower part of the lower part to act as a lowering part of the blocking part during rain flow, and the lowering member 5 lowers the discharge hole 6 and the lowering member 5 for the usual inflow of rainwater. The guide jaw (8) and the discharge hole (6) acts as a locking means that the support jaw (7) serves to maintain a constant angle.

DETAILED DESCRIPTION Referring to the accompanying drawings in detail, a drain plate 1 having a plurality of drainage holes 2 formed and installed to drain wastewater such as rainwater to the ground in FIG. 1, and sewage or sewage may be drained to a lower side thereof. In the conventional stormwater silo equipped with a manhole 11 to join,

The present invention comprises a plurality of guide grooves (9) formed in the inner circumferential surface of the manhole (11);

The upper surface is closed and the edge portion protrudes so that the blocking portion 3 is formed to block the drain hole 2 of the drain plate 1, and a sealing ring made of rubber material is installed on the upper portion of the blocking portion to completely block the back flow. And, inside the inner side is formed a foreign matter collecting portion (4) for collecting it when inflow of foreign matters. A plurality of guide jaws 8 and a plurality of discharge holes 6 are formed on the outer circumferential surface so that the guide grooves 1 can be lifted and lowered, and a hinge, which is a general coupling method, is formed at the lower end of the inner circumferential surface on which the discharge holes 6 are formed. It is shown that it is provided with a lifting member 5, the opening and closing plate 10 is installed to open and close the discharge hole (6).

In the above, it is preferable that the locking jaw 8a is integrally formed at the upper end of the guide jaw 8 so that the lowering member 5 is no longer lowered when the lowering member 5 is lowered to the upper end of the guide groove 9 inserted therein. Do.

In addition, the support jaw 7 is formed on the lower side of the inner circumferential surface on which the opening and closing plate 10 is installed so that the opening and closing plate 10 may be supported with a predetermined inclination in the open state, and the opening and closing plate 10 according to the reverse flow. It is desirable to allow this to close more smoothly.
