Description

TECHNICAL FIELD

[0001] The present invention relates to a foul odor blocking device for a sewer, and more particularly, to a foul odor blocking device for a sewer to block the entry of foul odor or insects generated from the sewer. BACKGROUND

[0002] Generally, a sewer or a manhole is one of drainage devices provided at the side of a road to discharge rainwater flowing from the road surface through a drain pipe.

[0003] The sewer or the manhole is generally in an open state, and thus various foreign matters are accumulated therein when it does not rain, and when it rains, the sewer and the drain pipe are blocked by the foreign matters accumulated on the sewer, so that not only rainwater or sewage cannot be normally discharged, but also the sewage of the drain pipe is reversed. In addition, the sewage accumulated in the sewer or the drain pipe generates foul odor, causing air pollution and the like, and thus the environmental problems caused thereby are very serious.

[0004] As a prior art to solve the above problems, Korean Granted Utility Model Publication No. 20-0461576 discloses a road side water inlet for preventing the inflow of dirt and foul odor, which includes a main body provided with a first passage and a second passage to introduce and discharge sewer water, a first gate to open the first passage when the sewer water is introduced through the first passage to be normally discharged, and to close the first passage when the sewer water is reversed from the first passage, a second gate to open the second passage when the sewer water is introduced through the second passage to be normally discharged, and to close the second passage when the sewer water is reversed from the second passage, an elastic pressure applying device to elastically apply pressure to the first gate in a closing direction so as to open the first passage when the flow pressure of the sewer water introduced through the first passage exceeds a set pressure, and a collection net provided on the second passage to collect foreign matters in the sewer water passing through the second passage.

[0005] Although the foreign matters contained in the sewage can be collected by the collection net, when the foreign matters block the collection net to a certain degree, not only the sewage is not easily discharged but also the reversed flow phenomenon occurs, and when cleaning, the collection net and the like need to be separately cleaned, which is inconvenient to use.

[0006] Although the foreign matters contained in the sewage can be collected by the collection net, when the foreign matters block the collection net to a certain degree, not only the sewage is not easily discharged but also the reversed flow phenomenon occurs, and when cleaning, the collection net and the like need to be separately cleaned, which is inconvenient to use.

[0034] Referring to the above figure, the odor-blocking device for sewers according to this embodiment can not only block odors, but also block insects from entering from the sewers.

[0035] According to the embodiment of the odor-blocking device 100 for sewers that can provide the above-mentioned effects, it includes a plate 110, a drain pipe 120 and a shielding membrane 130.

[0036] The plate 110 is placed on the upper part of the sewer manhole, and a steel grating plate is placed on top of the manhole. The plate is formed in the shape of a plate and has a through hole 111 in the center in the vertical direction.

[0038] The drain pipe 120 is connected to the through hole 111 through the bottom of the plate 110, and includes an upper pipe 121 and a lower pipe 122.

[0039] Specifically, the upper tube 121 is orthogonally connected to the plate 110.

[0040] Here, the upper tube 121 is tilted to approximately 5 to 10 degrees.

[0041] The lower tube 122 is connected to the lower end of the upper tube 121 at an angle of 75 to 85 degrees.

Figure 5 This is a side sectional view of an odor-blocking device for sewers according to a second embodiment of the present invention. Figure 6 According to the second embodiment of the present inventionFigure 2 Action graphics, Figure 7 This is a perspective view of a filter screen according to a second embodiment of the present invention. Figure 8 This is a front view of a filter screen according to a second embodiment of the present invention.

[0048] The odor-blocking device 200 for sewers according to this embodiment includes a plate 210, a drain pipe 220, and a shielding membrane 230.

[0049] The plate 210 is placed on the upper part of the sewer manhole, and a steel grating plate is placed on top of the manhole. The plate is plate-shaped and has a through hole 211 in the center in the vertical direction.

[0050] Here, the plate 210 is placed on a hanging platform formed along the upper circumference of the sewer manhole so that the steel grating is placed at the upper end of the sewer manhole.

[0051] Furthermore, the plate 210 may form a fixing boss 210a, which is bent upward so as to lock the edge of the plate into the mounting table for fixation, and the end of the fixing boss is bent toward the mounting table.

[0052] Although not shown, preferably, a rubber sealing gasket (not shown) is connected along the edge of the outermost end of the fixed boss 210a.

[0053] The drain pipe 220 is connected to the through hole 211 through the bottom of the plate 210, and includes an upper pipe 221 and a lower pipe 222.

[0054] Specifically, the upper tube 221 is orthogonally connected to the plate 210.

[0055] The lower tube 222 is connected to the lower end of the upper tube 221 at an angle of 75 to 85 degrees.

[0056] At this point, the drain pipe 220 is roughly formed. shape.

[0057] In addition, the end of the lower tube 222 is formed with a beveled shape.

[0058] At this point, the direction of the diagonal line is from the upper back to the lower front.

[0059] The shielding membrane 230 is connected to the end of the drain pipe 220 by a hinge 231, so that it is opened by the thrust of rainwater or sewage discharged from the drain pipe 220, or closed due to the load.

[0060] Furthermore, a filter screen 223 is provided at the end of the lower tube 222, which is connected to the shielding membrane 230. When the shielding membrane 230 is opened, the filter screen will unfold to cover the space between the lower tube 222 and the shielding membrane 230, thereby filtering foreign objects.

[0061] Preferably, the filter screen 223 is configured to allow rainwater and sewage to permeate.

[0062] In addition, an elastic body 222a connected to the filter screen 223 is provided at the upper inner end of the lower tube 222.

[0063] At this time, the elastomer 222a expands as the filter 223 unfolds when the shielding membrane 230 is opened.

[0064] When the shielding membrane 230 is closed, the elastomer contracts and pulls the filter screen 223, causing the filter screen to be introduced into the interior of the lower tube 222.

[0065] Preferably, the elastomer 222a has an elasticity that is less than the load of the shielding membrane 230 but greater than the load of the filter screen 223.

[0066] Additionally, the filter 223 includes: a first reinforcing body 223a connected to the filter along its central circumference; and a second reinforcing body 223b connected between the lower tube 222 and the outermost end of the shielding membrane 230.

[0067] Here, the elastomer 222a is connected to the first solidified body 223a and the second solidified body 223b at adjacent but interchangeable positions.

[0068] Therefore, when the elastomer 222a contracts, it pulls the filter screen 223 as a whole, causing the filter screen 223 to be introduced into the interior of the lower tube 222, thereby making the shielding film 230 airtightly attached to the end of the lower tube 222.

[0069] Furthermore, elastic ropes 222b are provided on the inner side of the lower tube 222, that is, on both sides of the elastic body 222a.

[0070] The elastic ropes 222b cross each other in a roughly "X" shape, with each end connected to both sides of the filter screen 223.

[0071] At this time, the elastic rope 222b has an elastic force equal to that of the elastic body 222a. When the filter screen 223 is introduced into the interior of the lower tube 222, they are pulled in opposite directions, thereby reducing the volume of the filter screen.

[0072] According to the present invention, an odor-blocking device for sewers is provided with a drain pipe for guiding rainwater, and a shielding membrane is provided at the end of the drain pipe, which opens due to rainwater or closes due to load. Therefore, it not only blocks odors generated from the sewers, but also blocks insects that enter through the sewers.

[0073] Furthermore, it should be understood that those skilled in the art can implement the invention in other specific ways without altering the technical concept or essential features of the invention. Therefore, the embodiments described above are merely exemplary at all levels and should not be construed as limiting. Consequently, the scope of the invention should be determined by the following claims, rather than by the detailed description above, and the meaning, scope, and all modifications and variations derived from equivalent concepts of the claims should be included within the scope of the invention.
