Description

A device to prevent bad smell from the manhole that can be cleaned by a cleaning car

The present invention relates to a manhole odor blocking device that can be cleaned by a cleaning vehicle, and more particularly, cleaning by a cleaning vehicle capable of blocking odors while allowing garbage such as vinyl and cigarette butts to be sucked and removed by the cleaning vehicle. It relates to a possible manhole odor blocking device.

In general, a manhole having a steel grating for draining rainwater from the road during a rainfall is formed on one or both sides of a road, and the manhole is connected to a drain or sewer to discharge rainwater to a water purification channel or a river.

At this time, soil, impurities, and trash flowing into the manhole such as rainwater and rainwater are discharged to the sewer.

As described above, all conventional manholes are installed mainly considering only the function of draining rainwater flowing on the road surface during rainfall. Most of the manhole structures are constructed with the upper inlet side wide open, and the upper inlet side in contact with the road surface has only a lattice-shaped steel grating installed, so the upper part in communication with the drainage or sewer is always kept open. Is done. Accordingly, various pests such as fly flies generated in drains or sewers, and odor caused by waste or sediment corruption leak to the ground through the manhole structure, contaminating the environment around the road with odor or pests. There is a problem that causes discomfort to passers-by.

In particular, the above-described phenomenon appears severely in the rainy season or the high temperature season, causing serious environmental hygiene problems. In addition, when road surface water frequently occurs, such as heavy rain or concentrated heavy rain in summer, the road surface water flows backward through the manhole structure located in the low-lying area due to the lack of road drainage treatment capacity or sewage treatment capacity of the drainage system and floods the road surface. There is a problem.

To prevent this, as a rain gutter for a manhole, it is published in Korean Patent Application Publication No. 2011-0023022. The posted rain gutter for manhole has a structure in which the front and rear opening and closing plates are pivotably hinged to the eco-receptor to open and close the space between the side plate and the side plate of the eco-receptor while the eco-receptor is installed on the manhole.

Therefore, according to the size of the manhole, it is difficult to install the eco-receiving plate and the front and rear opening and closing plates in accordance with the standard, and to install it in a manhole already installed on the road.

On the other hand, Korean Patent Application Publication No. 10-2009-0048527 and Korean Patent Publication No. 10-1266114 disclose a device for blocking odor and discharging harmful gas for sewers, and a manhole for preventing odor, respectively.

As the posted odor prevention manhole has a body installed under the manhole cover and a door hinged on the inside of the body, the door is rotated downward by the weight of rainwater in rainy weather, and rainwater is discharged along the sewer pipe. , Normally, the drain hole of the manhole is closed by the door so that the odor inside the sewer does not flow out.

Republic of Korea Patent Publication No. 2016-0118000 discloses a rain gutter for blocking odor and an odor blocking device for a manhole having the same.

Korean Patent Registration No. 10-893872 discloses a drain cover for preventing odors from manholes.

The conventional rain gutter or drain cover for odor blocking as described above has a structure that blocks the manhole at a position retracted from the lower surface of the grating to a predetermined depth.Therefore, the cleaning power or rain gutter or drainage by the brush of a sweeper cleaning the road There is a drawback in that cleaning cannot be done properly because suction power does not reach foreign substances such as cigarette butts, fallen leaves, vinyl, etc. supported on the cover.

Therefore, there is a problem that foreign matter that has not been cleaned flows into the sewer like rainwater when it rains, and for this reason, there is a problem that odors are more generated by garbage.

Since the main body 62 is formed in a flat plate shape and is tightly fixed to the lower surface of the grating 30 by the coupling unit 100, the trash is passed through the grating 30, that is, the rib 32 and the main body ( It is located inside the through hole 31 partitioned by 62).

Accordingly, in the process of cleaning the edge of the road divided by the boundary block by the sweeper, it is possible to clean the trash located in the through hole 31 of the grating 30. When cleaning the road, the sweeper has a structure in which trash is sucked by brushing and vacuum suction, so the sweeper of the sweeper passes through the upper surface of the grating 30 so as to be close to the upper surface of the grating 30. Garbage placed in the sphere 31 is removed. In particular, since the upper surface of the blocking door 67 is formed with a floating protrusion capable of injuring garbage such as vinyl, falling side, paper, etc., it is possible to prevent the garbage from being in close contact with the blocking door 67 and not being injured.

On the other hand, the coupling unit 100 for coupling the main body 62 of the grating 30 and the blocking unit 60 uses the coupling member 104 in a state in which the locking member 101 is supported by the grating 30. Thus, it is screwed to the fixing portion 103 formed on the main body 62, so that the coupling force can be increased. In particular, it is possible to prevent the body portion 62 from being deformed by the oil input and its own weight when a large amount of water flows in during a flood.

Particularly, as shown in FIG. 8, when the circumferential jaw 131 coupled to the edge of the grating 30 is formed at the edge of the body 62, the edge of the body 62 can be uniformly supported. (62) It is possible to increase the adhesion with the lower surface of the grating (30), and furthermore, the suction power of the cleaning vehicle can prevent dispersion of the suction power due to the inflow of outside air between the lower surface of the grating (30) and the main body (62). have.

In addition, the plurality of blocking doors 67 formed in the main body 62 block the inlet 61 by the weight of the weight member 68, and the inlet is opened by the rain load flowing in in the rain. ), rainwater flows in and is discharged. And when the discharge of rainwater is completed and the self-weight acting by the rainwater does not act on the blocking door 67, the door is closed by the load of the weight member 68 to prevent odors from being discharged from the inside of the manhole 20. Can be.

As described above, the manhole odor blocking device that can be cleaned by the cleaning vehicle of the present invention is combined and integrated by the grating and the coupling unit, so there is no need to install a blocking unit separately from the grating, and the garbage is supported on the lower surface of the grating by the cleaning vehicle. Cleaning is possible. This can solve a fundamental problem in that the garbage supported by the conventional device for blocking odor flows into the manhole when it rains.

The present invention has been described with reference to the embodiments, but these are merely exemplary, and those of ordinary skill in the art will understand that various modifications and equivalent embodiments are possible therefrom. Therefore, the true scope of protection of the present invention should be determined only by the appended claims.
