[Document 2] Republic of Korea Patent No. 10-0406853, November 12, 2003

In general, dirty wastewater and rainwater used in homes, factories and airports are discharged to sewers through sewers.

The sewer is provided with a sewer lid in which a plurality of water holes are constantly formed in order to solve the closed end of the sewer, except for water and foreign matters of a small size, to be blocked by inflow.

However, since the drain cover is formed with a plurality of water holes as described above, a bad smell caused by decay of foreign matters and dirty water flows out of the sewer and contaminates the surrounding air. In order to solve this problem, the odor blocking device for the sewer was installed under the sewer lid.

Such a conventional odor blocking device for sewers and the close contact with the bottom of the edge of the sewer; A guide hole formed in the center of the contact strip to guide the discharge discharged to the sewer; A body in which an inclined channel is formed so that an opening is formed in a vertical direction on one lower side of the guide hole; And an opening / closing plate coupled to an upper portion of the opening of the body to attract discharges discharged along the sewer to the sewer and to block the odor of the sewer.

A funnel-shaped body in which a hollow cylindrical substructure is integrally attached to the bottom of the hollow V-shaped superstructure, the diameter of which gradually decreases downward, and protrudes outward from the top of the upper structure. An annular projection to be placed directly under the manhole cover, a support attached to the outer surface of the body, a odor blocking port that is rotatable and can hold water as the support is a point; There is a structure composed of a return device provided near one end of the odor blocking port.

Therefore, when discharges such as rainwater are not discharged to the sewer, the closing plate and the odor blocking port can close the sewer so that the odor of the sewage outflow can be eliminated.

However, these conventional sewage odor blocking device is a structure that blocks the odor by opening and closing only one side of the body and the bottom of the body to a small size, respectively, so that when a large amount of discharge is discharged to the sewer in a short time, It will act as a barrier to smooth discharge.

As a result, a backflow occurs in the sewer, which causes a greater problem that wastewater and dirt are discharged out of the sewer with a bad smell in the sewer. In particular, when a lot of rain falls in a short time, it acts as a cause of flooding, which causes enormous property damage and casualties.

In addition, the switchboard and the odor blocking device have an installation structure that does not open and close even if the internal pressure of the sewer is increased by harmful gas, so that no harmful gas is discharged out of the sewer so that the worker enters the sewer for construction or cleaning. There is also a problem that causes injury or fire due to harmful gases.

The present invention has been invented to solve the above problems, in order to effectively prevent the backflow of the sewer to block the odor of the sewer and to provide a structure that can discharge the harmful gas of the sewage, and the support plate circumscribed at the top edge ; A water passage formed in a lower portion in the center of the support plate; A hopper-shaped odor blocking plate installed at a lower end of the channel and closing the channel; Wherein the malodor blocking plate is configured to be rotated on the malodor blocking plate to open / close a part of the malodor blocking plate, wherein the malodor blocking plate is formed in a “V” shape divided into two sides; The backflow prevention plate is composed of one side of the odor blocking plate as a whole, is installed to be automatically rotated by the heavy material installed on the working plate extending from one side of the odor blocking plate; Characterized in that the discharge opening and closing plate which is automatically rotated by the action of a plurality of harmful gas discharge hole and the heavy material installed on one surface in accordance with the increase in the internal pressure of the sewer to open and close the harmful gas discharge hole on the front and rear of the water passage, respectively. It is an object of the present invention to provide a sewer odor blocking and harmful gas discharge device.

The odor blocking and noxious gas discharge device for the sewer of the present invention can effectively block the odor of the sewer while preventing the backflow of the discharge discharged to the sewer, as well as to discharge the harmful gas inside the sewer frequently out of life due to harmful gas It is effective to effectively prevent damage or fire.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

The odor blocking and noxious gas discharge device 100 for the sewer of the present invention includes a support plate 1 rounded at the upper edge; A water passage (2) formed deep in the center of the support plate (1); A hopper-shaped odor blocking plate 3 installed at a lower end of the water passage 2 to close the water passage 2; In the odor blocking plate (3) installed to be rotated to open and close part of the odor blocking plate (3), the odor blocking plate (3) is divided into two sides "V" letter Formed into a shape; The non-return plate 5 is composed of one entire side of the malodor blocking plate 3, it is installed to be automatically rotated by the weight (7) installed on the working plate (6) extending from one side of the malodor blocking plate (3) Became; When the large amount of rainwater is introduced, the entire odor blocking plate 3 is opened, so that the backflow of the sewer 200 can be effectively prevented.

Weights 9 installed on one surface of the water passage 2 in accordance with the increase in the internal pressure of the drain 200 to open and close the plurality of harmful gas discharge holes 8 and the harmful gas discharge holes 8, respectively. The discharge opening and closing plate 10 is automatically installed by the action of.

In the drawings, reference numerals 11 and 12 are hinges for rotation of the backflow prevention plate 5 and the discharge open / close board 10, respectively, and 4 are reverse opening bumps for preventing the reverse opening of the backflow prevention plate 5, 300 is a sewer lid installed in the sewer (200).

The odor blocking and noxious gas discharge device 100 for the sewer of the present invention configured as described above is an apparatus installed in the sewer 200 so that the odor of the sewer 200 does not leak out.

In particular, the odor blocking and noxious gas discharge device 100 for the sewer of the present invention can effectively block the odor of the sewer 200 while preventing the backflow of the sewer 200, as well as automatically discharge the harmful gas of the sewer 200 What can be done is a big feature.

This is a heavy weight (7) installed in the working plate (6), which is composed of the entire back side of the malodor blocking plate (3), as shown in Figure 1, the malodor blocking plate (3) It is configured to be automatically rotated by a plurality of harmful gas discharge holes (8) and the harmful gas discharge holes (8) in the front and rear of the water passage (2), respectively, by the heavy material (9) It is due to the installation of the discharge opening and closing plate 10 to automatically open and close according to the internal pressure of the.

Therefore, when the discharge is discharged to the sewage in a large amount through the water passage 2 of the sewer 200 due to heavy rain, etc., the action of the discharge force and the weight (7) of the discharge force as shown in FIG. As a result, the backflow prevention plate 5 naturally rotates downward.

Then, while half of the odor blocking plate 3 is completely open, the discharge is discharged to the sewer through half of the open odor blocking plate 3.

Accordingly, the odor blocking plate 3 does not interfere with the discharge flow of the discharge, and thus the discharge is smoothly discharged from the sewer 200 without flowing back into the sewer.

Therefore, the present invention can completely solve the conventional problem that the odor blocking plate (3) is opened only to a predetermined size to prevent the discharge flow of the discharge, the reverse flow of the sewer is generated and the odor of the sewer 200 is more seriously leaked. Will be.

And if the discharge is not discharged to the sewer 200 for a while because the rain does not fall, the bad smell blocking plate (3) is not opened for a long time, the wastewater and foreign matter inside the sewer 200 is decomposed, harmful gas is generated. Toxic gas will increase the internal pressure of the sewer (200).

However, when the internal pressure of the sewer 200 rises due to the harmful gas as described above, the hazardous gas discharge hole 8 is maintained in parallel with the water passage 2 by the weight 9 as usual, as shown in FIG. 3. ) Is closed, the exhaust opening and closing plate 10 is instantaneously rotated upward by a predetermined amount.

Therefore, the noxious gas discharge hole 8 is instantaneously opened so that the noxious gas filled inside the sewer 200 is discharged out of the sewer 200 through the noxious gas discharge hole 8 opened.

Then, the internal pressure of the sewer 200 is lowered, and as a result, the discharge opening and closing plate 10 is returned to its original state by the heavy material 9, thereby blocking the harmful gas discharge hole 8, and again, the odor of the sewer 200 flows out again. To prevent it.

Therefore, the present invention effectively eliminates the conventional problems that caused no injury or fire due to harmful gas when the worker enters the sewer 200 for construction or cleaning because no separate harmful gas discharge hole 8 is provided. You can do it.
