Description

[Detailed Description of the Invention] The present invention relates to a fender device, and more specifically, the present invention relates to a fender device suitable for buffering ships such as deep-sea boats whose mooring point is always underwater and whose cross-sectional shape is approximately circular. This relates to improvements to the ship's side equipment.

For example, in the case of vessels such as deep-sea boats whose mooring point is always underwater and whose cross-sectional shape is approximately circular, the conventionally used floating fender is a bale-shaped fender, as shown in Figure 1. In the fender A, which has a structure in which a is simply moored to the quay G with A on its side, when the ship S comes alongside, as shown in the figure, the berth area between the side Sa and the floating fender a is extremely small. Above, floating fender a
There were problems such as rolling upwards and not being able to obtain a sufficient cushioning effect.

Recently, as shown in Figure 2, fixed solid fenders b have been installed directly and longitudinally on the quay G to prevent the fenders b from moving, and to prevent the vertical movement of the ship S and the tide level. A fender B that can cope with the movement of the joining point due to the difference has been proposed and used.

However, this structure requires a long and large fender b that greatly exceeds the required performance, resulting in high costs, and there is also the risk of damaging the fender side Sa due to partial compression and high surface pressure. The current situation is that there is a problem.

The present invention was developed as a result of studies to solve the above-mentioned problems.

Therefore, the purpose of the present invention is to improve the structure of the main body of the fender to create a fender that is ideal for use as a buffer for ships such as deep-sea boats whose mooring point is always underwater and whose cross-sectional shape is approximately circular. Our goal is to provide an excellent fender system.

In other words, in the present invention, the supply and exhaust valves are arranged in the upper mirror part of the fender body, which is made of a rubber-like elastic body with a reinforcing layer embedded in it and is formed vertically and hollow. The gist of the fender is a fender in which the parts are connected via a reinforcing member.

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

Figures 3 to 5 show a fender according to an embodiment of the present invention, Fig. 3 is a side view explanatory view showing the fender installed on a quay, and Fig. 4 shows the same air supply and exhaust valve. , FIG. 5a is an enlarged side view with a portion cut away showing the mounting portions of the water supply and drainage valve, reinforcing member, and mooring shackle; FIG. 5a is an enlarged side view with a portion cut away showing the air supply pipe; FIG. 5b FIG. 2 is an enlarged side view showing a water supply pipe with a portion cut away.

In the figure, E indicates a fender device according to an embodiment of the present invention, in which an upper mirror portion 11 of a fender main body 10 made of a rubber-like elastic body with a reinforcing layer K embedded therein and formed into a hollow vertically elongated body is provided with air supply and exhaust. A valve 20 and a water supply/drainage valve 30 are arranged, and the upper mirror part 11 and the lower mirror part 1
2 are connected via a reinforcing member 40.

To further explain this structure, the fender main body 10 has a rubber-like elastic body in which a reinforcing layer K is embedded.
As shown in the figure, it is constructed by forming a vertically elongated hollow body, and an upper plate 13 is integrally attached to an opening 11a provided in the center of the upper mirror portion 11 with a bolt 14 so as to cover the opening 11a. is attached to.

As shown in FIG. 4, a supply/exhaust valve 20 and a supply/drainage valve 30 are attached to the upper plate 13 at intervals, and on the outside of the central portion, a mounting is provided for attaching a mooring tie L. A bracket 16 for attaching the upper end of the reinforcing member 40 is integrally provided on the inner side of the hook 15.

In addition, a lower plate 17 is attached to the center of the lower mirror portion 12 of the fender body 10, and the reinforcing member 40 is attached between a bracket 18 provided on this lower plate 17 and the aforementioned bracket 16.

Reference numeral 50 denotes a balance weight for vertically maintaining the floating posture of the fender main body 10, which is detachably attached to the lower plate 17.

Further, a water guide pipe 31 is attached to the lower part of the water supply and drainage valve 30, and the lower end of this water guide pipe 31 reaches the bottom of the fender main body 10. Therefore, when the air pressure inside the fender main body 10 is increased, the water inside the fender main body 10 is drained to the outside via the water guide pipe 31 and the water supply/drainage valve 30, and the water inside the fender main body 10 is drained to the outside by this pressure. The amount of water in the main body 10 can be reduced, the floating depth of the fender main body can be freely adjusted, and the ship can always be brought alongside at a safe and optimum position.

In the figure, 60 is an air supply pipe, 70 is a water supply pipe,
La is a mooring shackle for attaching the mooring link L to the attachment hook 15.

As described above, the present invention has a supply/exhaust valve and a water supply/drainage valve arranged in the upper mirror part of the fender body, which is made of a rubber-like elastic body with a reinforcing layer embedded in it and is formed vertically and hollow. Since it is constructed by connecting the lower mirror section through a reinforcing member, the following effects can be achieved. That is, (1) Since this fender device moves up and down along with the ship depending on the tidal level difference, there is no need to attach a vertically long fender to the quay wall in consideration of the tidal level difference as in the past.

(2) Since this fender device can secure a large area of contact with the ship, the surface pressure can be made low and even, and damage to the ship can be prevented.

(3) Even if the underwater berth point changes depending on the size of the ship, the floating depth of the fender body can be freely adjusted by increasing or decreasing the amount of water within the fender body. Ships can be brought alongside in a safe and optimal position.

(4) As mentioned above, since water can be stored inside the fender body, the weight of the balance weight that maintains the vertical floating position of the fender body can be reduced. It is possible to reduce costs.

(5) Since the upper and lower mirror parts of the fender main body are connected by the reinforcing member, it is possible to reliably prevent the fender main body from losing its shape, and its durability can be greatly improved.
