Description

TECHNICAL FIELD [0001] The present invention relates to a grating device having a clogging alarm and an odor blocking function,

The present invention relates to a grating device having a clogging alarm and a malodor shielding function, and more particularly, to a grating device having an opening and closing plate for opening and closing a sewage inlet so that various insects or the like may come in from the sewer, In addition, when the upper part of the grating is clogged with various kinds of garbage and the rainwater and the sewage can not be discharged, it is possible to promptly notify the management office of the flooding damage, and the opening / closing angle To a grating device having a clogging alarm and an odor-blocking function which can improve durability by preventing an unreasonable external force from acting on the grill.

Generally, in the road, sewer is installed in the underground along the edge of the road so that sewage such as rainwater on the road can be smoothly flowed into the river, and the sewer which flows rainwater or sewage to the upper side of the sewer on the ground is spaced It is installed so that rainwater or sewage does not accumulate on the road when it rains.

As described above, most of the sewer installed on the road is provided with a sewer lid formed by molding a grating or a concrete made by welding or casting iron in a lattice shape to prevent the pedestrian from falling into the sewer, and a plurality of sewage inlets So that the sewage can flow smoothly into the sewer.

However, the sewer lid made of conventional grating or concrete as described above is usually constructed so as to open the inside of the sewerage through the sewage inlet of the sewer lid, and the relatively large sized dirt or dirt is discharged by the sewer lid Dirt such as cigarette butts or pieces of garbage that are filtered but small size can easily flow into the sewer inlet through the sewer inlet of the sewer lid and accumulate under the sewer.

When various kinds of dirt are repeatedly introduced and the accumulation amount of dirt accumulates inside the sewer, the sewer connected to the inside of the sewer becomes clogged, and when the inflow amount of the sewer increases suddenly such as heavy rainfall, the drainage is not smooth, .

In addition, there is a problem that harmful insects that can cause infectious diseases such as flies and mosquitoes inhabiting inside the sewer are leaked to the outside through the open sewage inflow, Occurs.

On the other hand, a place where a rubber plate or a cover plate is covered on a sewer lid to reduce the damage caused by odor or harmful insects. However, this causes a problem in that flood damage to the road is caused by preventing inflow of rainwater into the sewer in case of heavy rain.

In order to prevent the inflow of dirt among the above-mentioned problems, a filtering network of a wire mesh structure is conventionally installed to filter cigarette butts or small-sized garbage at the bottom of the sewer cover.

However, in the conventional method of installing the above-mentioned screen, since the screen is installed at the lower end of the sewer lid, the place where the pollutant is accumulated is deeply located at a considerable distance from the surface of the sewer so that the hand is inserted into the narrow space of the sewer inlet formed in the sewer lid It is impossible to simply collect the dirt. In this case, there is a problem in that it takes a lot of time and labor to collect the dirts by using the forceps which can be inserted into the narrow space of the sewage inlet, or to collect the dirt cover and collect the dirt.

In addition, since the dirt can not be collected easily as described above, the dirt accumulated is decayed due to being left to stand for a long time, and the smell is generated, and the state in which the dirt is piled up is easily observed.

In the conventional method of installing the screen, the inside and the outside of the sewer are still open, so that it is not a method to prevent the damage caused by odor and harmful insects generated in the sewer, and therefore improvement is required.

On the other hand, according to the related art related to the sewer lid, there are provided a registration method of the present invention, which is disclosed in Registration Practical Utility Model No. 20-0361514 (Registered on August 31, 2004), Registered Patent Publication No. 10-0734610 (Registered on June 26, 2007) And Shinan Bulletin No. 20-0303581 (registered date: Jan. 27, 2003).

In addition, since the additional apparatus of the prior art is installed at the lower end of the existing sewer lid, it is difficult to remove the dirt accumulated under the sewer lid as described above.

In addition, in the case of conventional grating, when bulky refuse covers the upper surface of the grating, there is a problem that the drainage can not be performed smoothly and the surrounding area is flooded.

In addition, in the above-mentioned prior art, there is provided an elastic member for elastically supporting the opening / closing plate so that the opening / closing plate is normally closed without inflow of sewage. When an external force close to the elastic limit is continuously applied to the elastic member, When the operation of maximally opening the plate is repeated for a long time, the durability of the elastic member is deteriorated or the elastic member is damaged, so that the opening / closing plate can not be properly supported, thereby causing a problem that the opening / closing plate is partially opened .

That is, if the durability of the elastic member is deteriorated or damaged as described above and the closing operation of the opening / closing plate is not properly performed, it is impossible to properly perform malodor prevention or backflow prevention function, which is the original purpose of the prior arts. It is a fact that a new way of being able to do is demanded.
