Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the following embodiments. This embodiment is provided to more fully describe the present invention to those skilled in the art. Thus, the shape of the elements in the figures has been exaggerated to emphasize a clearer description.

1 is a perspective view of a manhole 110 assembly 10 in accordance with an embodiment of the present invention.

Referring to FIG. 1, a manhole 110 assembly 10 includes a manhole 110, a manhole cover 120, and an auxiliary cover 200.

The manhole 110 is provided with a structure in which a hole is formed inside. The manhole 110 can be provided to the structure. The structure may be an offshore structure such as a passenger ship, a cargo ship, a floating production storage and offloading unit (FPSO), a floating storage and regasification unit (FSRU), and the like. In addition, the structure may be a building installed for a certain purpose on land.

The manhole 110 can be connected to the structure. The manhole 110 can be secured to the structure. The manhole 110 is provided in a ring shape, and a hole is formed inside. A support portion 111 is provided inside the manhole 110. The supporting portion 111 may be positioned at a predetermined distance downward from the top of the inner surface of the manhole 110. The support portion 111 may be formed in a ring shape along the inner surface of the manhole 110. The supporting portion 111 may be formed integrally with the manhole 110. The supporting portion 111 may be separately formed from the manhole 110 and then fixed to the manhole 110 by welding or the like.

2 is a longitudinal sectional view showing a state in which the manhole cover is placed on the manhole;

Referring to FIGS. 1 and 2, the manhole 110 may be opened and closed by a manhole cover 120. The manhole cover 120 may be provided in a shape corresponding to the manhole 110. For example, the manhole cover 120 may be formed to have a smaller size than the hole in the inside of the manhole 110. Therefore, when the manhole cover 120 is positioned inside the manhole 110, the side of the manhole cover 120 and the inner surface of the manhole 110 can be separated by a predetermined distance.

The manhole cover 120 may be made of a metallic material. The manhole cover 120 may be provided in a plate shape corresponding to the shape of the manhole 110. The manhole cover 120 may be provided with a fastening portion 121. The fastening portion 121 is formed to protrude outward from the manhole cover 120. For example, the fastening portion 121 may be formed separately from the manhole cover 120 and may be fixed to the side of the manhole cover 120 or the lower surface of the manhole cover 120 by welding or the like. The fastening portion 121 may be formed integrally with the manhole cover 120 so as to extend outward from the side of the manhole cover 120 or outside the lower surface of the manhole cover 120. The fastening part 121 and the support part 111 are formed with holes corresponding to each other and can be fastened with bolts or the like.

Fig. 3 is a perspective view of the auxiliary lid viewed from below, and Fig. 4 is a view showing a positional relationship when the auxiliary lid is placed on the upper surface of the manhole cover.

Referring to FIGS. 3 and 4, the auxiliary lid 200 is provided to cover the upper side of the manhole cover 120. The auxiliary lid 200 includes a body portion 210 and a fixing protrusion 220.

The body portion 210 provides the framework of the auxiliary lid 200. The body portion 210 is provided in a plate shape. The body 210 may be provided with an area larger than a hole formed inside the manhole 110. Therefore, when the auxiliary lid 200 is positioned on the upper surface of the manhole cover 120, the outer side of the body 210 can be located on the upper surface of the manhole 110 or outside the manhole 110. The body portion 210 may be provided to have magnetism. Therefore, when the auxiliary lid 200 is positioned on the upper surface of the manhole cover 120, the auxiliary lid 200 can be fixed by a magnetic force acting between the auxiliary lid 200 and the manhole cover 120. In addition, the body 210 may be provided with a flexible material. For example, the body 210 may be formed of nitrile-butadiene rubber. Thus, the auxiliary lid 200 can be minimized in its ease of use and damage during use.

At least one fixing protrusion 220 may be provided on the bottom surface of the auxiliary lid 200. The fixing protrusion 220 may be integrally formed with the body 210. The fixing protrusion 220 may be formed separately from the body 210 and then fixed to the bottom of the body 210 by an adhesive or the like. The fixing protrusion 220 may be provided to be positioned between the bolt B and the bolt B when the auxiliary lid 200 is positioned on the upper surface of the manhole cover 120. [ When the auxiliary lid 200 is positioned on the upper surface of the manhole cover 120, the fixing protrusion 220 is supported by the bolts B and the inner surface of the manhole 110, .

The upper portion of the manhole 110 is additionally shielded by the auxiliary cover 200 so that the space formed between the inner surface of the manhole 110 and the manhole cover 120 is not exposed to the outside Do not. Therefore, foreign matter can be prevented from accumulating in the space between the inner surface of the manhole 110 and the manhole cover 120.

Fig. 5 is a bottom side view of the auxiliary lid according to another embodiment, and Fig. 6 is a longitudinal sectional view of the auxiliary lid of Fig.

Referring to FIG. 5, the auxiliary lid 300 includes a body 310 and a fixing protrusion 320.

The auxiliary lid 300 is provided in a ring shape. The body portion 310 provides the framework of the ancillary lid 300. When the auxiliary lid 300 is installed, the inside of the body 310 is in contact with the outside of the upper surface of the manhole cover 120 and the outside of the body 310 is covered with the upper surface of the manhole 110 or the outside of the manhole 110 As shown in FIG. Therefore, the space formed between the inner surface of the manhole 110 and the manhole cover 120 can be shielded by the auxiliary cover 300. [ The body portion 310 may be provided such that the inner end and the outer end are thinner than the middle portion. Therefore, in the state where the auxiliary lid 300 is installed, it is possible to minimize the problem that the operator falls over the auxiliary lid 300 and the like. The body portion 310 may be provided to have magnetism. Also, the body 310 may be provided with a flexible material. For example, the body 310 may be formed of nitrile-butadiene rubber.

At least one fixing protrusion 320 may be provided on the bottom surface of the auxiliary lid 300. The fixing protrusion 320 may be integrally formed with the body 310. The fixing protrusion 320 may be formed separately from the body 310 and then fixed to the bottom of the body 310 by an adhesive or the like. The fixing protrusion 320 may be provided to be positioned between the bolt B and the bolt B when the auxiliary lid 300 is positioned on the upper surface of the manhole cover 120. [

The foregoing detailed description is illustrative of the present invention. In addition, the foregoing is intended to illustrate and explain the preferred embodiments of the present invention, and the present invention may be used in various other combinations, modifications, and environments. That is, it is possible to make changes or modifications within the scope of the concept of the invention disclosed in this specification, within the scope of the disclosure, and / or within the skill and knowledge of the art.
