The present invention relates to a device for preventing the backflow of odor mainly in the manhole drainage drained to the sewer pipe buried underground in civil works such as residential areas or roads.

In general, residential buildings such as houses use water for cooking, bathing or cleaning. At this time, the water used is sanitized at the manhole drain located at the edge of the house or building. In order to effectively block the odor of the air formed by decay in the drain, especially in the manhole drain of the conventional sewage pipe was not able to effectively provide the purpose.

Therefore, in the rear roads, which mostly pass through residential areas, the walls are covered with thick vinyl wallpaper for simple use, and in many cases, the odors flowing from the manhole drains are temporarily used.

In summer aerators, sewage pipes for sewage pipes used at the edges of roads around the residential areas mentioned above are drained to drains for re-use of sewage, such as wastewater mixed with drained water or baths. As the net structure is formed to filter the sewage, most of the sewage mixed with the sewage is accumulated in the drainage hole, and the drainage is not smoothly drained by blocking the drainage. Also, in the underground drainage pipe, especially in summer, The blocking of polluted air was difficult to use hygienically at drains in residential areas.

In addition, indoors located at low places such as undergrounds in buildings have limitations in preventing the prevention of indoor pollution caused by odors flowing back from the sewage of the sewer pipe drains.

It is an object of the present invention to provide a drainage role only when rainwater flows in the rainy season and the like, as well as providing effective drainage of the drainage water discharged from the sewer pipe drainage described above and blocking odor inflow.

In other words, a part of the drainage water flowing in the sewage pipes is stagnated like sediment in the drainage and prevents the leakage of odor due to decay, and when rainwater starts to drain into the drainage safety net due to heavy rain, it naturally occurs. In providing a device configured to be drained.

In order to achieve the above object, the present invention, in the manhole of the sewer pipe connected to the drain hole formed by assembling the safety net in the proper place so that the drainage on one side of the residential area and the road, the sewage flows into the living waste water, etc. The swelling connected to the blocking plate used for blocking odor is fixed to the buoyancy of rainwater due to the rainwater collected in the inner space of the container while fixing the container in which the drainage hole is formed while being assembled from the wall of the drainage to the hook. The invention is characterized in that it is configured to open and close the through hole of the safety net by fixing the blocking plate with a fixed rod to move up and down by the intermittent, forming a drain hole intermittently in the blocking film so that rain water is stored in the container at the beginning of flowing rain water The buoyancy force moves the barrier plate, and also drains the container Hayeoseo intermittently formed in hayeoseo completely Jagger rainwater that rain comes down, and then left in the container for a said blocking plates invention for preventing reverse flow of sewer manholes for the device, characterized by configured to give covered with the safety net.

Therefore, the detailed description thereof will be described based on the accompanying drawings,

Figure 1 is a partially cut away partial perspective view of the main part of the present invention disassembled, Figure 2 is a sectional view of the main part showing the assembled state of the drainage shown in Figure 1, Figure 3 is a sectional view taken along line AA in Figure 2, Figure 4 1 is a partial cross-sectional view of an embodiment of the container which is the main part in FIG. 1, FIG. 5 is a cross-sectional view taken along line BB in FIG. 4, and FIG. 6 is a main cross-sectional view showing the present invention in use.

That is, as shown in Figures 1 to 3, in the place where the sewage pipes 73 buried at the roadside, etc. are connected at a predetermined interval, assembled on the step 65 of the bottom surface 66 fixed to the ground of the roadside. In the drain port 51 formed by assembling the safety net 52 is formed by the through hole 53 is fixed while being fixed, the ring is fixed to the upper side of the drain space in the drain port 51 formed on the bottom of the bottom 66 Assembling the container 55 to be fixed by the hook (63) hanging on the (62), and a plurality of auxiliary outlet (61) intermittently formed in the lower side of the container 55, and the drain ( Form 68).
In addition, the bookkeeping 54 is inserted into the inner space of the container 55, the bookkeeping 54 is a fixing rod 57 in the upper direction to the through hole 53 of the safety net 52 described above By fixing the blocking plate 56 while passing, it is configured to cover the through-hole 53 of the safety net (52).

In addition, if rainwater accumulates in the container 55 along the auxiliary drainage inlet 67 of the blocking plate 56 in rainy weather, the swelling 54 is formed by the buoyancy, which is formed on the fixing rod 57 protruding from the upper side. When the blocking plate 56 is raised by the rod 58, the through hole 53 of the safety net 52 is opened to allow a large amount of rainwater to flow in, while being inserted while maintaining a loose gap in the inner space of the container 55. The bookkeeping 54 is drained to the outlet 65 while raising the buoyancy.
In addition, when the rain is over, the rain water contained in the container 55 is discharged to the auxiliary discharge port 61, the blocking plate 56 is lowered by the lowering of the bookkeeping 54, the through hole 53 of the safety net 52 Covered is an invention configured to block the decayed harmful gas such as odor flowing from the drain 51.

At this time. Rainwater flows into the auxiliary drainage inlet 67 drilled in the blocking plate 56 than the amount of rainwater discharged to the auxiliary discharge port 61 intermittently formed at the lower side of the container 55 due to the amount of rainwater falling down. When the amount is small, since there is no amount of rain water accumulated in the container 55, buoyancy is not applied to the swelling 54, which is the main part of the present invention, so that the blocking film 56 does not move.

However, since the rainwater is accumulated in the container 55 due to the amount of rainwater, the bookkeeping 54 receives the buoyancy so that the rainwater is discharged in a steady state.

At this time, piled up in the sewage pipe (73) provides to wash away the debris of the decayed sewage with rain water.

As described above, when a small amount of rainwater comes down, rainwater does not accumulate in the container 55, and thus, the blocking plate 56 continues to pass through the safety net 52 due to the non-operation of the bookkeeping 54. 53) is a device that serves to block the leakage of odor accumulated in the sewer pipe (73).

Here, the projection bar 58 formed on the fixed rod 57 is secured by the safety net 52 when the bookkeeping 54 is raised by buoyancy, and the wide area discharge space 64 shown in FIG. ) Is a useful space to provide a sufficient discharge space when the rain water is discharged to the drain (68).

In addition, the description of the embodiment of the main portion of the present invention, as shown in Figures 4 to 6, the conveyance projecting in the vertical direction at a predetermined interval to the inner wall surface of the inner space of the container 55 to be said The bookkeeping 54 is projected and fixed to the upper side as described above so as to be inserted in a loose form in the inner space formed after the protrusion 71 is formed, and at the upper end, a blocking plate ( 56 is fixed, and the lower side of the container 55 is formed by protruding the guide wall 69 protruding in a conical shape to the center portion in a circular state while forming an outlet 70 at a predetermined size in the center portion. Invention.

That is, in rainy weather, rainwater is conical guide wall 69 formed on the lower side while passing through the moving space 72 between the transfer protrusions 71 through the auxiliary drainage inlet 67 formed in the blocking plate 56. When rainwater pushes the lower side of the bookkeeping 54 with the guidance of the bookkeeping 54 is buoyant to rise above the buoyancy, so that the blocking plate 56 connected to the fixed rod 57 is raised, the safety net ( By opening the through hole 53 of 52, the rainwater is introduced into the inner space of the drain 51 in large quantities, the bookkeeping 54 is an invention configured to drain rainwater by obtaining a sufficient buoyancy.

Here, the projection bar 58 formed on the fixed rod 57 is secured by the safety net 52 when the bookkeeping 54 is raised by buoyancy, and the wide area discharge space 64 shown in FIG. ) Is a useful space to provide a sufficient discharge space when the rain water is discharged into the drain (68).

Accordingly, the present invention as described above is essential in the sewage pipe drainage is formed underground buried, especially in the summer season, while the outflow of odor to the sewage of the drainage flowing in the sewer pipe is blocked, so that a small amount of sewage flows into the drain without leaking odor The invention is economical and durable because it is prefabricated.
