The present invention relates to an insulation cover for preventing an electric shock accident of an electric manhole, and more particularly, to an insulation cover for preventing an electric shock accident of an electric manhole coupled to a lid of a manhole to block current from being transmitted to a pedestrian.

In general, after installation of electric cable, telephone line, cable TV cable, water and sewage pipe, city gas pipe, etc., it is possible to make the machine and human access to facilitate the cleaning and inspection of them and the removal and repair of obstacles. As a facility, manholes are formed at regular intervals.

The manhole is installed in the shape of a circle, a square, an ellipse, or the like through concrete pouring work, and an entrance sealing means for selectively sealing or opening the entrance so that an operator can enter and exit the upper entrance around the entrance.

The doorway sealing means consists of installing a manhole body made of steel around the doorway and then installing a manhole cover made of cast iron which is heavy in weight to prevent the safety of the internal facilities and safety accidents.

However, the conventional manhole cover is made of a cast iron material that can be energized as an element material, in particular, when a heavy rain falls during the rainy season, an electric shock flows from the manhole, and accidents occur in which a pedestrian hides frequently. Since no basic measures are in place, tens of thousands of manholes installed in various parts of the country's roads serve as 'summer mines'.

This electrocution is caused by the electricity flowing from the wire joints buried in the manhole to the pedestrian through the metal manhole cover. Especially, on rainy days, the electric current leaks into the rain and the electric current is increased. This increases the risk of electric shock.

In consideration of the problems caused by the electrocution, a separate insulating rubber plate is placed under the manhole cover, and an electric tape is not wound on the wire connection part. However, the work is very cumbersome and there is still a risk of leakage. I'm doing it.

In other words, the conventional manhole cover merely serves to cover the manhole, and as the airtightness due to leakage is greatly reduced, when the inside of the manhole is completely submerged, water flowing through the current flows out of the manhole and flows over the road. It was exposed to as it is.

In addition, in the case of the manhole body on which the manhole cover is seated, there is no provision for any preparedness due to an electric shock, so that current is transmitted to the pedestrian through the manhole body.

The present invention is to solve the above problems, is coupled to the lid of the manhole to block the electric current is transmitted to the pedestrian, to prevent the electric shock accident insulation of the electric manhole to prevent from being damaged by the impact applied from the outside The purpose is to provide a cover.
