Abstract

PURPOSE:To prevent damage to a shock absorber float by a method in which shock absorber floats are attached to the peripheral wall of a sea structure and surrounded by a float support frame movable to every direction. CONSTITUTION:Shock absorber floats 2 are attached to the peripheral wall of a sea structure 1 and surrounded by a float support frame 3 movable to every direction. The frame 3 is obtained by assembling synthetic resin plates, pipes, or bars 3a through joints 3b. Trouble with corrosion and damage such as breakage of the floats 2 by contact with mooring chains can thus be prevented.

Description

[Detailed description of the invention] : Industrial application field: This invention relates to a floating shock absorber, and more specifically, the invention relates to a floating shock absorber, and more specifically, it surrounds a shock absorber float arranged on the outer peripheral wall of an underwater structure. , a floating buffer that does not increase the blockage rate by not integrating the underwater structure and the buffer float support frame, even when there are restrictions due to the river flow blockage rate, by installing a buffer float support frame that can move left and right. It is related to the device.

[Prior art]

Conventionally, navigating ships have come into contact with the side walls of underwater structures,
BACKGROUND ART In order to prevent damage to a part of a ship due to a collision, a buffer device including a plurality of buffer floats moored is provided around an underwater structure.

As shown in FIG. 3, for example, this type of buffering device includes a plurality of buffering floats 12 moored via chains 13 around an underwater structure 11 constructed of concrete or the like.

[Problem to be solved by the invention; However, the buffer float 12 moves up and down due to waves and swings from side to side, so that the moored chain 1
There was a problem in that contact with the buffer float 12 caused wear and damage to the buffer float 12. Further, since the buffer float 12 moves up and down and swings while slidingly contacting the underwater structure IFI 11, there is a problem that it may be damaged due to contact with the concrete underwater structure 11.

[Purpose of the invention]

This invention was devised by focusing on such conventional problems, and supports the buffer float without using a mooring chain, and prevents direct contact with underwater structures, so that the buffer float can be supported without using a mooring chain. It effectively prevents the buffer float from being damaged or broken, and also effectively prevents the buffer float from flying out when a ship etc. collides with it.Furthermore, the buffer float support frame also has buoyancy, so that it can be easily used when a ship collides with the buffer float. The object of the present invention is to provide a floating shock absorber having a shock absorbing function due to crushing.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a buffer float support frame that surrounds the upper surface and outer circumferential surface or the upper surface, lower surface and outer circumferential surface of the buffer float, and is movable in the vertical and horizontal directions surrounding the outer circumference of the underwater structure. The gist of this document is that it has been established.

Further, the gist is that a sliding plate made of resin, on which the buffer float slides, is provided at a portion of the outer peripheral surface of the underwater structure that comes into contact with the buffer float.

[Action of the invention]

In this invention, a plurality of buffer floats arranged around an underwater structure are supported by a buffer float support frame that is configured to surround the underwater structure and is movable in vertical and horizontal directions. The buffer float will not be damaged or broken due to contact with the chain, and the buffer float will not slide or swing due to direct contact with the middle structure, so the buffer float Cannot be damaged.

[Embodiments of the invention] The present invention will be described in detail below based on the accompanying drawings.

FIG. 1 is a plan view of a floating shock absorber embodying the present invention, and FIG. 2 is a side view of FIG.
2 shows a plurality of buffer floats arranged around the underwater structure 1. The buffer floats 2 are provided with a buffer float supporting frame 3 that surrounds the outer periphery of the underwater structure and is movable in the vertical direction. Also: the upper surface, lower surface and outer peripheral surface are surrounded.

The buffer float support frame 3 is made up of a plurality of plate-like members or ? Xij! Joint 3 with book vibrator material, bar material 3a, etc.
B is framed through plasti as its material, considering seawater corrosion.

Preferably, the material is made of resin such as resin.

Further, at a position on the outer peripheral surface of the underwater structure 1 that contacts the buffer float 2, a sliding surface is provided to prevent the buffer float 2 from being damaged due to sliding contact between the concrete underwater structure 1 and the buffer float 2. The moving plate 4 is attached via bolts (not shown) or the like.

The sliding plate 4 is preferably made of a corrosion-resistant material such as nylon, polyethylene, or Teflon.

This invention is constructed as described above, and the structure 1 is constructed as follows.
The plurality of buffer floats 2 arranged around the underwater structure 1 are supported so as to be surrounded by the buffer float support frame 3G which is configured to surround the underwater structure 1 and is movable in the vertical direction. The buffer float 2 will not be damaged or broken due to contact with the mooring chain, and the underwater structure l and the buffer float 2 will not slide or swing due to direct contact. The buffer float 2 will not be damaged.

In addition, the buffer float support frame 3 is attached to the underwater structure to be protected.
Because it surrounds the area, the engineering energy caused by collision can be dispersed,
The entire buffer float 2 around the underwater structure 1 can absorb the energy.

;Effect of the invention:- This invention provides a buffer that surrounds the upper surface, outer peripheral surface or L surface, lower surface, and outer peripheral surface of the buffer float as described above, and that surrounds the outer periphery of the underwater structure and is movable in vertical and horizontal directions. The provision of a float support frame reduces problems such as corrosion, and effectively prevents the buffer float from being damaged or broken due to contact with the mooring chain.Furthermore, the strength of the buffer float support frame increases the buffering effect. In addition to being able to obtain
It is possible to obtain an effect similar to that of the buffer float itself, and to prevent the buffer float from flying out in the event of a collision with a ship.

In addition, a resin sliding plate on which the buffer float slides is provided at the part of the outer peripheral surface of the underwater structure that comes into contact with the buffer float, so that the underwater structure and the buffer float are in direct contact and do not slide or oscillate. This has the effect of effectively preventing damage to the buffer float.
