Description

Blastwall structure

The present invention relates to an explosion-proof structure.

An offshore structure including FPSO (Floating Production Storage and Offloading) is likely to explode due to gas and oil due to its operational characteristics. If an explosion occurs in an offshore structure, it can lead to fatal structural damage or sinking. Therefore, it is necessary to reduce the possibility of an explosion in the design stage and secure the stability of the structure in the event of occurrence.

When an explosion accident occurs from an arbitrary module of an offshore structure, an explosion shock is transmitted to another module, so that various modules may explode together to cause a major accident. Also, when explosion is transmitted to a residence, To prevent this, a blastwall is installed between the modules.

Korean Patent Laid-Open No. 10-2015-0004185 discloses an explosion-proof wall and a construction method thereof for an explosion-proof wall.

In general, explosion-proof walls are designed to withstand explosive pressures. In a module where an explosion occurs, a larger shock can be transmitted due to the reflection shock wave against the explosion pressure. That is, when the explosion pressure is transmitted to the explosion-proof wall, due to the explosion-proof wall structure of the blocking structure, the pressure is increased due to the generation of the reflected wave,

The above-described background technology is technical information that the inventor holds for the derivation of the present invention or acquired in the process of deriving the present invention, and can not necessarily be a known technology disclosed to the general public prior to the filing of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

2 is a perspective view of an explosion-proof structure according to an embodiment of the present invention. FIG. 3 is a cross-sectional view of the explosion-proof structure shown in FIG. 2, Fig.

1 to 3 show a structure 10 of an offshore structure, modules 21, 22 and 23, an explosion-proof structure 100, a main explosion-proof wall 110, a sub explosion-proof wall 120, , Roller walls 141 and 142, and concave walls 151 and 152 are shown.

The explosion-proof structure 100 according to an embodiment of the present invention is disposed between the modules 21, 22, and 23 installed on the deck as an upper structure of an offshore structure, So that the influence on the module 21 located on the opposite side is minimized and the occurrence of the secondary accident is prevented in advance.

The explosion-proof structure 100 according to the present embodiment includes a main explosion-proof wall 110 and a sub-explosion-proof wall 120 as a basic framework.

The main explosion-proof wall 110 is installed adjacent to the module 21 to be protected, for example, a utility area. The main explosion-proof wall 110 serves as a general explosion-proof wall and serves to block a blast wave traveling from the front.

The sub-explosion-proof wall 120 is installed adjacent to a module 22, for example, a production area where explosion risk is high and explosion is expected.

The sub explosion-proof wall 120 prevents the explosion waves traveling from the front from being directly transmitted to the main explosion-proof wall 110, and receives the explosion wave to disperse the explosion pressure first.

The sub-explosion-proof wall 120 has a structure in which a plurality of sub-explosion-proof wall modules 130 are continuously disposed in front of the main explosion-proof wall 110.

A plurality of sub-explosion-proof wall modules 130 are arranged in a line, and the explosion waves are dispersed into the sub-explosion-proof wall modules 130 and enter.

The sub-explosion-proof wall module 130 has a first roller wall body 141 and a second roller wall body 142, which are concave in a direction expected to be generated due to the progress of the explosion wave, And includes a first concave wall body 151 and a second concave wall body 152 disposed in a portion thereof.

The roller walls 141 and 142 are rotatable around a central axis in the vertical direction.

A first concave wall body 151 is disposed outside the first roller wall body 141 and a second concave wall body 152 is disposed outside the second roller wall body 142.

The first concave wall body 151 and the second concave wall body 152 are concaved in the direction toward the rear so that the explosion wave propagating from the front is changed by the concave surface to form the sub explosion-proof wall module 130 To the central portion of the frame.

Explosion waves gathered at the central portion move to the rear of the sub explosion-proof wall module 130 through the gap between the first roller wall body 141 and the second roller wall body 142. Here, the first roller wall body 141 and the second roller wall body 142 may rotate in engagement with each other.

In this process, the first roller wall body 141 and the second roller wall body 142 rotate. Part of the explosion load due to the explosion wave is used to rotate the first roller wall body 141 and the second roller wall body 142 And the explosion wave passing through it significantly reduces the explosion load. Therefore, when reaching the main explosion-proof wall 110 located behind the sub explosion-proof wall module 130, the explosion load is considerably reduced and can be sufficiently blocked by the main explosion-proof wall 110.

The blast waves passing through the gaps between the first roller wall body 141 and the second roller wall body 142 do not advance perpendicularly to the main explosion-proof wall 110 but are transmitted to the main explosion- So that the impact of the explosion load on the main explosion-proof wall 110 is reduced.

The direction of rotation of the first roller wall 141 and the second roller wall 142 may be opposite to each other. Referring to FIG. 3, the first roller wall 141 rotates counterclockwise, 142 can rotate clockwise.

According to the present embodiment, the explosion wave proceeding by the explosion generated in the front is dispersed primarily by the auxiliary explosion-proof wall, and the force for rotating the roller wall is used to reduce the explosion load on the main explosion-proof wall .

FIG. 4 is a perspective view of an explosion-proof structure according to another embodiment of the present invention, and FIG. 5 is a plan view of the explosion-proof structure shown in FIG.

4 to 5 show the explosion-proof structure 200, the main explosion-proof wall 210, the sub explosion-proof wall 220, the roller walls 231 and 232, and the convex walls 241 and 242.

The explosion-proof structure 200 according to another embodiment of the present invention is also disposed between the modules 21, 22, 23 installed on the deck as an upper structure of the offshore structure 10 as shown in FIG. 1, Thereby minimizing the influence on the module 21 located on the opposite side and preventing the occurrence of a secondary accident in advance.

The explosion-proof structure 200 according to the present embodiment also includes a main explosion-proof wall 210 and a sub-explosion-proof wall 220 as a basic skeleton. However, I will explain.

A sub-explosion-proof wall 220 is installed in front of the main explosion-proof wall 210.

The sub explosion-proof wall 220 prevents the explosion waves traveling from the front from being directly transmitted to the main explosion-proof wall 210, and receives the explosion wave to disperse the explosion pressure first.

The sub-explosion-proof wall 220 has a third roller wall body 231 and a fourth roller wall body 232, which are convex in a direction expected to cause the explosion wave to advance and are arranged adjacent to the center portion, And the first convex wall body 241 and the second convex wall body 242 disposed in the first and second convex walls 241 and 242, respectively.

The roller walls 231 and 232 are rotatable about a center axis in the vertical direction and are disposed such that the third roller wall body 231 and the fourth roller wall body 232 are engaged with each other and rotated.

The first convex wall body 241 is disposed outside the third roller wall body 231 and the second convex wall body 242 is disposed outside the fourth roller wall body 232.

The explosion wave proceeding to the center portion is dispersed and propagated to both edges by the rotation of the third roller wall body 231 and the fourth roller wall body 232.

The third roller wall body 231 and the fourth roller wall body 232 are rotated to disperse the explosion wave which has progressed to the center portion and the third roller wall body 231 is rotated clockwise , And the fourth roller wall body 232 rotates counterclockwise.

The third roller wall body 231 and the fourth roller wall body 232 may be independently rotated by separate driving parts, or when one of the two roller walls is rotated by the driving part, the other may engage and rotate in the opposite direction .

The first convex wall body 241 and the second convex wall body 242 are convex in the direction toward the rear so that the propagation direction of the explosion wave propagating from the front side is changed by the convex surface, As shown in Fig.

The blast waves dispersed by the rotation of the third roller wall body 231 and the fourth roller wall body 232 at the central portion also proceed to the edge portions along the first convex wall body 241 and the second convex wall body 242 .

Therefore, the explosive load due to the explosion wave hardly reaches the center portion of the main explosion-proof wall 210, and the explosion waves gathered at the both edge portions are not perpendicular to the main explosion-proof wall 210, So that the explosion pressure on the main explosion-proof wall 210 is considerably attenuated.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
