Abstract

The present invention relates to a grating automatic opening and closing device using a spring cover installed in the upper part of the manhole and the sewer, the spring cover serving as a hole blocking plate of the grating (GRATING), and automatically opening and closing the spring cover There is a semi-circular rain gutter groove, so when it rains, the semi-circular rain gutter rainwater gathers to have a certain weight, and the rotation moment between the rain gutter rainwater weight and the conduction spring is operated, by the conduction spring coupled to the lower part of the grating frame. Normally, the grating cover is closed by the hole of the grating, and when water enters the semicircular rain gutter groove during rainfall, it automatically opens and closes by weight.

It is a grating that can be opened and closed automatically with a rotation moment when a small amount of rain is collected in the semicircular rain gutter, by fixing a plate with a small semi-circular rain gutter which can collect rainwater in the rain below the general grating frame.

The present invention relates to a device that can be automatically opened and closed when a certain amount of rainfall is introduced by using the weight rotation moment of rainwater in the grating as a grating installed on the upper manhole and sewers

In general, manholes and rain gutters are buried in the places where roadsides and sewage collect, and drains are collected to discharge and collect rainwater and domestic sewage. In the bottom of the manholes, sewers are usually connected to rivers. Living sewage is collected in manholes and continues to flow through sewers buried underground. In the upper part of the manhole and the sewer, various kinds of steel grading are installed to prevent large sized dirt from entering the manhole and the sewer, and at the same time, the lid function of the manhole and the sewer is parallel.

The grating is usually seen inside the manholes and sewers without any rainwater inflow, which hinders the beauty of the city center, and becomes a place for throwing cigarette butts and various wastes. It affects the environment, and during the rainy season, the pollutants accumulated in the rain gutters not only prevent rainwater from entering the sewer, but also have a problem that the sewage flows back due to the flooding of the river to increase the damage.

The present invention is to solve the above problems, usually the hole of the grating is closed to prevent cigarette butts and garbage throwing, the infiltration of fallen leaves around the trees, and to prevent the odor of the person in the manhole and sewer, as well as to remove the contaminants Reduce manpower input

The present invention provides a grating automatic opening and closing device using a semi-circular rain gutter spring cover, the cover serving as a hole blocking plate of the grating 10, the semi-circular rain gutter 22 and the constant rain water to automatically open and close the cover It is coupled to the conduction spring 24 by weight and both sides of the grating to couple the cover and the conduction spring to the grating frame.

Figure 1 is a grating perspective view, Figure 2 is a cover 21 with a semi-circular rain gutter 22 and the iron core and the semi-circular rain gutter for fixing it to the frame is a spring (24) that is conducted when the rain exceeds a certain weight and rotating bar ( Through 25).

2 shows that the semicircular rain gutter collects rainwater to weigh more than a certain amount, and the lower part of the semicircular rain gutter has a fine hole 23 to discharge the rain water in the semicircular rain gutter when the rain stops.

One side of the cover has an iron core which can be fixed and rotated to the frame 20 and a conductive spring 24 which can be reversed and restored.

Normally, the cover 21 is naturally stretched by the conduction spring and the hole of the grating is closed by the spring elastic force. Therefore, the inside of the manhole and the sewer can not be seen with the naked eye, and the inflow of cigarette butts and garbage can be prevented.

During the rainy season, rainwater accumulates in the semicircular rain gutter 22 according to the water inflow load, and the cover is pushed down to automatically open the grating hole, and when there is no water inflow, the rotating bar 25 is moved by the falling spring. It rotates and closes automatically.

As described above, the grating automatic opening and closing device using the cover with the semicircular rain gutter groove is normally closed by a spring cover, thereby preventing the inflow of garbage and cigarette butts and preventing the odor of manholes and sewers from rising to the ground. In rainy season, it is automatically opened according to the inflow of water into the semicircular rain gutter groove, so that it can be drained smoothly. In addition, there is no fountain inside the manholes and sewers, which has the effect of creating a pleasant environment without harming the city's beauty.

Claims (1)

A semi-circular rain gutter opening and closing device using a cover 21 having a semi-circular rain gutter groove 22 attaches a semi-circular groove cover between the grating frames, and a micro hole 23 capable of draining rain water is provided at the bottom of the semi-circular rain gutter groove 22. This microhole has no weight due to rainwater in the semicircular groove in normal or small rains to block the circulation of air in and out of the manhole, and combines two to four conducting springs 24 in the semicircular groove to frame both sides of the grating. The grating with rain gutters, characterized in that the rain water can pass through if it exceeds a certain rain weight.
