KR-20260063863-A - Rainwater gutter cover structure for preventing garbage inflow and odor reduction using buoyancy

Abstract

The present invention relates to a rainwater catcher cover structure utilizing buoyancy to prevent the inflow of waste and reduce odors. Specifically, as a rainwater drain cover structure installed on the upper part of a sewer grating to close the upper part of the sewer, thereby preventing waste from entering the sewer and reducing odors generated by discharging odors from inside the sewer to the outside, This invention relates to a rainwater drain cover structure utilizing buoyancy for preventing waste inflow and reducing odors, wherein the cover is made to float due to buoyancy caused by the water rising inside the drain during rain, thereby enabling drainage.

Description

Rainwater gutter cover structure for preventing garbage inflow and odor reduction using buoyancy The present invention relates to a rainwater catcher cover structure utilizing buoyancy to prevent the inflow of waste and reduce odors. Specifically, as a rainwater drain cover structure installed on the upper part of a sewer grating to close the upper part of the sewer, thereby preventing waste from entering the sewer and reducing odors generated by discharging odors from inside the sewer to the outside, This invention relates to a rainwater drain cover structure utilizing buoyancy for preventing waste inflow and reducing odors, wherein the cover is made to float due to buoyancy caused by the water rising inside the drain during rain, thereby enabling drainage. Generally, drainage channels are formed along one or both sides of the road to drain rainwater during rainfall, and rainwater catchment structures are installed in the drainage channels at predetermined intervals as needed. At this time, the above-mentioned rainwater catchment structure discharges rainwater, soil, and debris flowing in with the rainwater into the sewer, and a steel grating is installed at the upper opening of the rainwater catchment structure to filter out the inflow of relatively large debris, such as surrounding leaves or plastic, that is swept in by the rainwater. As such, all conventional rainwater drainage structures are generally installed with the primary function of draining rainwater flowing on the road surface during rainfall in mind. To further elaborate, most conventional rainwater catchment structures are configured with a widely open upper inlet side and adopt a structure in which only a grid-like steel grating is installed on the upper inlet side in contact with the road surface, so the upper part of the rainwater catchment structure communicating with the drainage channel or sewer always remains open. Consequently, there was a problem in which foul odors resulting from the decay of waste or sediment, as well as various pests such as gnats originating from drains or sewers, leaked to the ground through storm drain structures, frequently polluting the surrounding road environment with odors and pests, and causing discomfort to nearby people and passersby. In particular, the aforementioned phenomenon appeared severely during the rainy season or seasons with high temperatures, causing serious environmental hygiene problems. In addition, in cases where surface water frequently occurs, such as during heavy rain or torrential downpours in the summer, there were problems such as surface water backflowing through the structures of storm drains located in low-lying areas and flooding the road surface due to insufficient drainage capacity of drainage channels or sewage systems. Therefore, we propose a technology that resolves the various problems described above by closing the sewer under normal circumstances, while enabling the drainage function by causing the cover to float due to buoyancy during rain. In addition, by closing the sewer normally, it is possible to overcome the limitation where grating alone cannot prevent the inflow of waste. In this regard, Registered Patent Publication No. 10-0935102 describes a device for blocking odors and backflow in sewers. The above technology comprises mounting a catch net on the upper side, wherein the drainage holes formed inside are formed in a grid or circular shape, one or more packing mounting grooves are formed around the outer perimeter to allow for the installation of packing, and an insertion section is formed facing inward along one side; mounting a rainwater collector on the lower side of the catch net, comprising a case having a predetermined height and size and having an internal through-hole formed therein, a connecting part formed at the lower side of the case and connected to the drain or sewer, and a support plate formed protruding from the upper side of the case, integrally formed; mounting a catch slope plate on the interior of the case, comprising a mounting part in which a foreign matter storage container is pressure-mounted, formed in the center and having a connecting hole formed along the outer perimeter inside, a contact part fixed to the inner surface of the case, and an inclined part connecting the mounting part and the contact part at an angle, integrally formed therein; and between the insertion part of the catch net and the catch net and the rainwater collector, formed by selecting one of vinyl, synthetic resin having a predetermined thickness, or a thin metal plate, and a cut section at a position corresponding to the drainage holes. It is formed by including a blocking plate that is installed. However, as the aforementioned configuration involves too many structures, it incurs high costs for application and presents the problem of requiring the interior of the sewer to be modified.
