Description

Improved Grating And Grating Structure In Ditch Using The Same}

The present invention in the grating structure and the grating structure of the drain is installed on the top of the drain, simple installation and disassembly with a simple structure and function to perform an effective anti-theft function and to filter foreign matter and grating structure of the drain using the same It is about.

FIG. 1 is a photograph of a conventional grating, and FIG. 2 is a photograph of a grating structure of a conventional drain hole provided with conventional grating.

As shown in Figures 1 and 2, the grating (manhole cover) having a grid of grid (grid) is installed on the upper part of the drain or manhole installed in the periphery of the road and the building.

Due to the recent economic crisis, gratings are frequently stolen. Therefore, unsealed measures such as welding gratings are used, but it is difficult to maintain them, so it is urgent to provide a separate anti-theft device.

In addition, the grating serves as a kind of filter to allow rainwater and sewage to pass, and to prevent passage of materials of a predetermined size such as waste.

However, the conventional grating does not operate properly as a filter device because the gap of the grid is too wide to properly filter out contaminants thrown from the outside. In this case, foreign matter passing through the grating blocks the drainage pipe of the drain, there is a problem that the decayed sewage decays in the clogged drain, causing a bad odor, there are problems such as inhabiting various pests threaten human health.

In order to solve this problem, a number of improved drainage structures have recently been proposed and used.

Looking at the operation method of the conventional improved drainage structure, usually the hinged drainage door is kept closed so that the odor inside the drainage does not diverge, when the water flows in the drainage door is opened by the load of water drainage If the water is accumulated in the lower opening and closing portion, which is one side of the opening and closing wing, the drainage opening is rotated by the load of the water.

However, such a conventional improved drainage structure is inexpensive because it replaces the existing drainage main body, etc., and adopts a mechanical driving method such as a hinge method, there is a problem that the manufacturing precision is required and the manufacturing cost increases.

In addition, when the function of the hinge device is degraded by dust or oil, etc., the rotation is not properly performed, and in order to prevent such a problem, continuous maintenance is required, and there is a problem such as excessive repair cost in case of failure.

Therefore, in the case of such a conventional improved drainage structure is practically avoided to use.

The present invention is proposed to solve the conventional problems as described above. The purpose is as follows.

First, it is intended to provide an improved grating and a grating structure of a drainage drain using the same, which are not interlocked with each other by grating.

Second, it is to provide an improved grating and a grating structure of the drain hole using the same by attaching a filter to the lower part of the grating to perform an effective filter function to filter out foreign substances.

Third, by introducing a hinge method for opening and closing of the grating to improve the grating structure of the drain and drain grating using the grating hinge lifting the opposite side of the grating hinge shaft to remove the foreign matter filtered by the filter easily.

Fourth, by introducing a hinge method for opening and closing of the grating to lift the opposite side of the grating hinge shaft with manpower to provide an improved grating easy to maintain, such as cleaning the drain hole and the grating structure of the drain hole using the same.
