Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to improvements in mooring devices for floating breakwaters and other floating marine structures.

``Prior art'' When several floating wave breakers are installed in succession, if waves act parallel to or at a certain angle to the installation reference line (hereinafter referred to as the vertical direction), the wave breakers will move vertically. There is a possibility of a collision.

Conventional floating breakwaters are shown in Figures 3 and 4.

In Fig. 3, 1 is a floating body, 2 is a vertical mooring line, 3 is an anchor block for vertical mooring, 4 is a horizontal mooring line, 5 is an anchor block for horizontal mooring, and between the floating body 1 are mooring lines 6
It is a concatenation of.

Figure 4 shows a floating body 1, a horizontal mooring line 4, a horizontal mooring anchor block 5, and a mooring line 7.
It is connected by .

"The problem that the idea tries to solve" The conventional method had the following problems.

() When a vertical mooring chain is installed in the direction of the axis of a floating body, the chains of adjacent floating bodies will interfere with each other, causing rapid wear and tear on the chain, making it impossible to ensure the specified service life.

() When connecting a new floating body to an existing floating body, it is extremely difficult to install vertical mooring chains and anchors directly below the existing floating body.

I am corrected.

"Means for solving the problem" This invention solves the above conventional problems,
In a planar position holding device for a floating wave bank, in which rectangular floating bodies connected in a row are moored to anchor blocks via vertical and horizontal mooring chains, the vertical mooring chains are attached in a direction that is inclined with respect to the longitudinal direction of each floating body. This is a planar position holding device for a floating wave bank, in which a pair of horizontal mooring chains are stretched from the center of the floating body in both directions and in a direction perpendicular to the longitudinal direction of each floating body, on both sides of the floating body. The purpose is to prevent the horizontal movement of a single floating body.

"Embodiment" An embodiment of the present invention is shown in FIGS. 1 and 2.

11 is a rectangular floating body connected in a line, 12 is a vertical mooring chain that forms an angle θ with respect to the longitudinal direction in both directions from the center A of the floating body 11, and 13 is a vertical mooring anchor block that connects the vertical mooring chain 12. do. 1
4 is a horizontal mooring chain that is perpendicular to the floating body 11 on both sides of the floating body 11, and 15 is a horizontal mooring anchor block that connects the horizontal mooring chain 14.

Further, the floating bodies 11 are installed at intervals corresponding to the permissible movement amount +α due to underwater deformation (extension allowance) of the vertical mooring chain 12.

"Action" When waves act in the vertical direction of the floating body 11, the floating body 1
1 tries to move horizontally due to this, but due to the underwater deformation (extension) of the vertical mooring chain 12,
The amount of movement of the floating bodies 11 is limited, and collisions between the floating bodies 11 are prevented.

Furthermore, since the vertical mooring chain 12 is connected to the center of the floating body 11, no rotational moment is applied to the floating body 11.

"Effects of the invention" Since the present invention is the above-mentioned device, () the amount of movement of each floating object is limited by underwater deformation of the vertical mooring chain against waves that are at an angle to the longitudinal axis of the floating object; In addition, collisions between floating bodies are prevented, and a shock absorbing device such as a fender is not required.

() When connecting a new floating structure to an existing floating structure,
It is easy to install vertical mooring chains and anchors directly under the existing floating structure.
