Description

Weight for water surface structure shaking prevention

The present invention is applied to all types of floating water structures, and in particular, in any form, such as offshore houses, offshore rest areas, offshore fishing grounds, offshore workshops (including factories, offices, warehouses, etc.), cargo handling facilities in ports, large-scale land bridges, etc. Reduced shaking of floating water structures that can be installed separately from anchors on applicable floating water structures and reduce shaking by suppressing the sudden movement or movement of floating water structures due to waves or external forces. It is about the shake reduction weight

In general, floating objects such as ships, etc., rapidly move up, down, left, and right due to external forces such as waves or winds, which often cause damage to facilities or damage to human life.

Anchor, like the existing anchor, is a tool for fixing the anchoring position of floating objects. It is heavy, complicated to install or dismantle, and there is a limit to reducing the shaking of floating objects due to tides, waves, and wind. And when an external force such as wind is strong, a phenomenon in which the connecting rope or chain connecting the anchor is broken may occur.

However, it is true that large aquatic structures are structurally safe against overturning and shaking, but small water structures are vulnerable to overturning and shaking. Conventionally, a method of distributing the weight by using an additional buoyancy device, etc. has been used to reduce the shaking of such a small water structure, but this method has a problem in that the cost is high and the volume of the buoyancy device becomes large.

In Korean Patent Application Laid-Open No. 10-2010-0121078, when a floating structure is connected to a floating structure in a state of floating underwater while mounted separately from an anchor, the movement of the floating structure occurs due to sudden vertical movement or external forces such as waves and wind, the inside of the body There is disclosed a floating structure equilibrium state maintaining device that can maintain the equilibrium state of the floating structure by suppressing the movement of the floating structure by using the weight of the fluid accommodated in the body and the drag generated during movement by an external force,

There is described a water equipment for crossing underwater beams using a barge moving support and an anti-sway device, characterized in that this connection is configured to enable the hook part to flow,

In Korean Utility Model Publication No. 20-2011-0003375, a stick of a predetermined length and a stick fixing tube formed in a cylindrical shape so that the stick can be penetrated and fixed; and a frame connecting the stick fixing tube and the small water structure so that the stick fixed to the stick fixing tube faces vertically and long, wherein the stick is configured to be detachable from the stick fixing tube, and the stick is separated from the stick fixing tube It can be seen that when the stick is immersed in the water by inserting and fixing it in the water, the shaking prevention device of the small water structure is disclosed to prevent the shaking of the small water structure floating on the water surface.

As a security point for these structures, the present applicant has proposed a weight for preventing shaking of a floating floating structure in Utility Model Registration No. 20-0455682.

The above-mentioned technology was used as a right, but the problem that the bending phenomenon of the wing occurred during use, the problem that the structure is greatly affected by the water pressure as it is used in water, and the folding of the wing is easy as the wet wing sticks There were problems such as not being done properly, and the lower center of gravity being too large to limit installation and movement.
