Safety cover for drain grating in private areas {SAFETY COVER FOR DRAINAGE GRATING}

The present invention relates to a safety cover for a drain grating, and more specifically, to a safety cover for a drain grating, which is detachably attached to the drain of a drain provided in a private area such as a parking lot, and blocks the inflow of foreign substances while discharging rainwater through the drain hole. If the drain hole is clogged due to accumulated trash, the middle cover floats and opens the drain hole at the bottom of the middle cover to allow rainwater to drain smoothly. In addition, it is a safety cover for drain grating that can stably support vehicles such as passenger cars. It's about.

Generally, drains are formed at the edges of roads to drain rainwater caused by rainfall, and drains are provided at regular intervals in the drains to prevent flooding due to heavy rain. And in these drains, gratings with multiple drain holes are installed for the safety of pedestrians and vehicles.

In addition, drains are formed in drainage channels formed in private areas such as parking lots to prevent flooding, and gratings are also installed in these drains. However, the grating installed in the private sector is different from the grating installed on public roads in that its structure is not clearly limited.

However, conventional grating forms rather large drainage holes for smooth drainage of rainwater, so foreign substances such as surrounding trash and fallen leaves easily flow into the drainage holes, and these foreign substances are deposited in the drainage channels, ultimately reducing the drainage capacity of the drainage channels. In addition to the problem of deteriorating the water quality, there is also the problem of causing a safety accident where a pedestrian's shoes or heel of a shoe gets caught in the drain hole of the grating and the pedestrian falls.

Accordingly, a method of covering the upper part of the grating with a cover having a small drain hole has been recently developed. This drain grating cover blocks the inflow of foreign substances while allowing water to escape into the drain through the drain hole, thereby preventing a decrease in drainage capacity.

However, the conventional drain grating cover has a problem in that smooth drainage is not achieved when waste collected by rainwater blocks a small drain hole.

In addition, the conventional cover for drain grating is coupled to the grating and protrudes from the surface of a parking lot, etc., so there is another problem in that an impact occurs on the vehicle while driving in the parking lot while passing the grating cover.

Meanwhile, in Publication Patent No. 10-2017-0049471, a filter plate is installed on a step formed at the entrance of the drain to prevent foreign substances from entering the drain, and a drain cover is installed on top of the step, The filter plate is formed by cutting a plurality of cut drainage portions on the filter plate main body, which is formed of a synthetic resin plate or a thin metal plate with a predetermined elasticity, and the cuts are formed in an open curved shape so that a part of the cut drainage portion is connected to the filter plate main body, so that the inner portion of the cut portion is formed. It is configured to form an opening and closing surface connected to the filter plate main body and the connecting neck, and a portion of the plurality of cut drainage formed on the filter plate is cut in the form of an open curve so that it is connected to the filter plate main body, so that the cut portion is normally used. The opening and closing surface formed in a random shape on the inside remains flat and spread out, preventing foreign substances from passing through the thin cut part and allowing only sewage to pass through. When it rains and the amount of water drained increases, the opening and closing surface inside the cut part is exposed to water pressure. A filter plate for road drains that bends downward and allows sewage to drain immediately has been proposed and disclosed,

Registered Patent No. 10-1208906 discloses a cover including an iron plate with perforations and an upper and lower plate made of synthetic resin and formed integrally with the upper and lower surfaces of the steel plate, and the upper plate has a permeable portion through which rainwater can pass, and The side of the cover is configured to connect the covers to each other by forming a hook with a hook hole and a connecting protrusion that is inserted into the hook hole of another cover.
