Description

[Detailed description of the invention] [Technical field of the invention] The invention consists of a main body block that is slidably arranged around an underwater structure, and a plurality of blocks that are removably attached to the main body block near the gutter on the side where the ship enters. The present invention relates to an improvement of a floating shock absorber comprising an elastic shock absorbing material.

[Conventional technology]

It consists of a main body block that is slidably placed around underwater structures, and a plurality of elastic cushioning materials that are removably attached to the main body block near the swamp on the ship entry side. The important structural points of the floating shock absorber, which absorbs the energy of the collision when floating objects such as driftwood collide with each other to prevent damage to ships and protect underwater structures, are based on the research of the inventor of this invention. According to the following: That is, (1) It must be possible to reliably prevent small vessels such as fishing boats from entering the connecting parts of each elastic cushioning material of the above-mentioned floating shock absorber, thereby preventing damage to the vessel.

(2) If a ship collides with the floating shock absorber at an angle, the ship's bow should be able to turn smoothly and damage caused by the collision can be minimized.

(3) When a ship collides with a floating shock absorber, the impact energy can be dispersed and absorbed by multiple elastic shock absorbers.

(4) If the cross-sectional shape of the elastic cushioning material is circular, there is a risk that a ship will run aground on the elastic cushioning material, so this must be reliably prevented.

[Problem that the invention attempts to solve]

However, at present, there is still no floating shock absorber that satisfies all of the above-mentioned points.

[Purpose of invention]

The object of the present invention is to provide an excellent floating shock absorber that satisfies all the points mentioned above.

[Structure of the idea]

In other words, the present invention is a floating shock absorber consisting of a main body block slidably arranged around an underwater structure, and a plurality of elastic shock absorbers detachably attached to the main body block near the water intrusion side of the main body block. A supporting frame is attached at intervals to the ship entry side of the main body block, and a continuous guide fence is attached via the support frame to cover the ship entry side of each of the elastic cushioning materials. The gist of this article is a floating shock absorber.

[Embodiments of the Invention] The present invention will be specifically described below by way of embodiments with reference to the drawings.

1 and 2 show a floating shock absorber according to an embodiment of the present invention, and FIG. 1 is an explanatory plan view showing the floating shock absorber installed around a bridge pier, that is, an underwater structure; FIG. 2 is an enlarged cross-sectional view taken along the line XX in FIG. 1.

In the figure, E denotes a floating shock absorber according to an embodiment of the present invention, which includes a main body block 10 that is slidably arranged around the underwater structure G, and a shock absorber that can be attached and detached from the main body block 10 near the stuttering water on the ship intrusion side. It is composed of a plurality of elastic cushioning materials 20 that can be attached.

In the present invention, in particular, a support frame 30 is attached at intervals to the ship entry side 10a of the main body block 10, and this support frame 3
0 to the ship entry side 2 of each elastic cushioning material 20 through
A continuous guide fence 40 is attached to cover 0a.

To further explain this structure, the support frame 30 is made of steel, FRP, etc.
The main body block 1 is located between each of the elastic cushioning materials 20, that is, at each connecting portion of each elastic cushioning material 20.
It is attached to the ship entry side of 0.

Note that, as shown in FIG. 2, it is preferable for safety to form the support frame 30 into a frame shape so that it can be easily deformed in the event of a ship collision.

Further, the guide fence 40 is made of a material such as a rubber-like elastic body, FRP, or a thin strip-shaped steel material that can be expected to have a membrane force in the event of a ship collision, and each support frame 30 is provided with each elastic buffer material 20. It is attached continuously so as to cover the ship entry side 20a.

Note that this guide fence 40, as shown in FIG.
It is preferable to attach it so as to form a continuous wall surface.

Further, in this embodiment, the main body block 10 is made of a plastically deformable material or a combination of a plastically deformable material and a brittle fracture material, and the plastic deformation material undergoes plastic deformation and/or the brittle fracture material undergoes brittle fracture during a ship collision. In addition to absorbing collision energy by utilizing the elastic shock absorbing material 20, the elastic shock absorbing material 20 is provided with sufficient strength to withstand the reaction force of the elastic shock absorbing material 20 until it is compressed by a predetermined amount.

On the underwater structure G side of this main body block 10,
In this embodiment, as shown in FIGS. 1 and 2, a sliding member 50 is attached.

In this embodiment, the sliding member 50 is made of a material such as a rubber-like elastic body or synthetic resin that does not damage the underwater structure G and has excellent sliding properties, and as shown in the figure, the sliding member 50 is made of a material such as a rubber-like elastic body or a synthetic resin. They are arranged vertically at intervals on the mounting surface side of the main body block 1, and facilitate vertical movement of the floating shock absorber E due to fluctuations in the tide level, currents, waves, etc.
0 and the underwater structure G can be prevented from being damaged.

Note that the sliding member 50 may be fixed to the wall surface of the underwater structure G or may be suspended.

In this embodiment, the elastic cushioning material 20 is a so-called pneumatic fender in which air is sealed inside, and a mounting tool 60 such as a chain, a shackle, a turnbuckle, etc. is attached to the upper part of the main body block 10.
Although a plurality of pieces can be attached and detached by means of a screwdriver, a plurality of pieces are fixedly attached.

In addition to pneumatic fenders, the elastic cushioning material 20 may be a solid fender material such as bolts or the like, which is constructed so that the main body block 10 has buoyancy and is formed mainly of a rubber-like elastic body on the upper part of the main body block. It can be used by being removably fixed using the attachment means.

[Effect of idea]

As described above, in the present invention, a support frame is attached at intervals to the ship entry side of the main body block, and a continuous guide fence is attached via the support frame to cover the ship entry side of each of the elastic cushioning materials. Therefore, the following effects are produced.
In other words, (1) Even if a small vessel such as a fishing boat intrudes into the joints of each elastic buffer of the floating shock absorber, the joints of each elastic buffer will be protected by the continuous guide fence as described above. Since it is covered, it is possible to reliably prevent the ship from entering the joints of the respective elastic cushioning materials, thereby preventing damage to the ship.

(2) Furthermore, even if the ship collides with the floating shock absorber at an angle, the guide fence allows the ship to turn the ship's bow smoothly. Therefore,
Damage to ships due to collisions can be minimized.

(3) Furthermore, when a ship collides with this floating shock absorber, the impact energy can be dispersed by the continuous guide fence. Therefore, impact energy can be absorbed by the plurality of elastic cushioning materials, and each elastic cushioning material can be downsized.

(4) Furthermore, the continuous guide fence can prevent damage to the elastic cushioning material caused by drifting objects such as driftwood.

(5) Furthermore, even when the cross-sectional shape of the elastic cushioning material is circular as in this embodiment, it is possible to reliably prevent a ship from running aground on the elastic cushioning material. Therefore, damage to the ship can be prevented.
