Description

Functional Grating

The present invention relates to a functional grating. More particularly, the present invention relates to a functional grating, and more particularly, to an opening / closing unit having upwardly restoring force to open / close a plurality of sewage inlets formed between a plurality of outer frames and inner frames, The present invention relates to a functional grating for supporting an opening and closing plate rotatably about an axis of rotation of a rotatable shaft and supporting the rotatable shaft through a reinforcing bracket inserted and fixed to the outer frame and the inner frame.

Generally, a drainage channel is installed in the underground along the edge of a road so that sewage such as rainwater on the road can flow smoothly to the river, and a drainage pipe for introducing sewage to the upper side of the drainage channel is installed at intervals, So that the rainwater does not accumulate on the top of the water tank.

If the drainage condition of the road becomes poor, it will be a big obstacle to the driving of the vehicle, so it is very important to smooth the roadway and the drainage of the roadway. However, if the sewer is left in an open state, there is a fear that a pedestrian may fall into a sewer, and a large foreign matter is inserted, among other things. For this purpose, most of the sewers installed on the road are equipped with a grating manufactured by welding or casting iron in a lattice shape.

On the other hand, the above-described grating has a drawback that the sewage inlets are formed so that the rainwater can be inserted therein, and thus the inside of the sewage is not well visible, and the backwash is generated due to heavy rain or odors are generated.

In addition, since small dirt such as cigarette butts or scrap pieces flows through the sewage inlet, it is accumulated at the lower part of the sewer so that odor is generated due to accumulated dirt for a long period of time or hinders smooth flow of sewage, There were additional problems.

In order to overcome such a problem, as a prior art document, "Grating having a function of blocking dirt and odor" of Utility Model No. 20-0475383 (Registered on Apr. 21, 2014, hereinafter referred to as "prior art document" It has been proposed.

As shown in FIG. 1, in the grill installed on the upper portion of the sewer, the sewing water inlet is closed by the open / close plate at the time of normal operation by providing the open / close plate for opening or closing the sewage inlet The grating is formed to prevent the generation of odor, prevent foreign matter from being inserted into the sewer, and to open the opening / closing plate selectively due to the load due to rain during rain.

However, the prior art document has a limit in that the opening and closing angle is limited to a certain angle or less, and the drainage can not be performed smoothly because the opening and closing plate is elastically supported by the leaf spring.

Also, in case of heavy rain, when the plate spring fully supports the load, deformation is applied to the leaf spring, the restoring force is lost and the original function can not be performed. In order to replace or repair the plate spring, There was also a maintenance difficulty in which time and cost for separating the opening and closing plate and the rotating shaft were additionally added.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an apparatus and a method for efficiently supporting a load caused by rainwater while smoothly discharging rainwater, And it is an object of the present invention to provide a functional grating which can prevent an odor from being generated because the inlet can be shut off and the opening and closing can be made constant.
