The present invention relates to a safety buoy of a manhole cover and, more specifically, to a safety buoy of a manhole cover, wherein a horizontal safety buoy is installed in the lower part of the manhole cover inside the manhole, and when the manhole cover is opened by torrential rain, the safety buoy rises to the water by water pressure and buoyancy, so that a pedestrian can identify the upper part of the opened manhole, and an auxiliary warning part is unfolded together with the safety buoy, so that the position of the opened manhole can be confirmed with a more reliable warning, thereby preventing a safety accident such as a manhole fall in advance.

    본 발명은 맨홀뚜껑의 안전부표에 관한 것으로서, 보다 상세하게는 맨홀내부에서 맨홀뚜껑의 하부에 수평의 안전부표를 설치하여, 집중호우로 맨홀뚜껑이 개방되는 경우, 수압 및 부력에 의해 안전부표가 물위로 떠오르면서 개방된 맨홀의 위를 보행자가 식별할 수 있도록 하는 것이며, 안전부표와 함께 보조경고부가 함께 펼쳐지면서 이러한 더욱 확실한 경고와 함께 개방된 맨홀의 위치를 확인할 수 있어, 맨홀 추락 등의 안전사고를 사전에 예방할 수 있도록 하는 맨홀뚜껑의 안전부표에 관한 것이다.
