Abstract

The invention discloses a manhole cover device with a protection function, and relates to the technical field of manhole cover protection. The manhole cover device comprises a manhole cover body and adeck, wherein the manhole cover body is hinged at the upper end of the deck through a connecting piece; a movable groove is fixedly arranged on the right side of the manhole cover body; a rotating rod is rotationally connected to the inside of the movable groove through a rotating shaft; and the side of the rotating rod is fixedly connected with a first supporting protection mechanism. Through the arrangement of the first supporting protection mechanism, a second supporting protection mechanism, a third supporting protection mechanism and light reflective strips, the first supporting protection mechanism, the second supporting protection mechanism and the third supporting protection mechanism can be connected through hitching mechanisms during nighttime work of the manhole cover device, and the connected first supporting protection mechanism, the second supporting protection mechanism and the third supporting protection mechanism can prevent people from accidentally falling into a manhole. In addition, the light reflective strips on the sides of the first supporting protection mechanism, the second supporting protection mechanism and the third supporting protection mechanism alertpeople to the manhole at night, so that the possibility of accidents can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of manhole cover protection, in particular to a manhole cover device with a protective function. Background technique [0002] The manhole cover is divided into A, B, and C according to its use. Each type of manhole cover has its required position. Generally, the model is determined according to the ship design and classification society regulations. At the same time, the standard size of the manhole cover is 420X380, which can accommodate one person in and out, and the larger size is used for accidents below, and the ambulance personnel can transport the wounded out safely. [0003] During the manufacturing and installation of ships, construction workers often accidentally fall from the manholes arranged horizontally on the deck, resulting in major personal safety accidents that could result in either death or injury, especially at night, where the possibility of accidents is even greater. It has been grea...
