Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides electric power between anchored ships suspended on the water surface or in the water by means of a mooring device, or between the ships and land via cables laid on the bottom of the water.

This relates to equipment that supplies and receives water, etc.

In recent years, with the progress of ocean development, ships are increasingly being moored offshore and used for oil storage tanks, exploration facilities, oil extraction facilities, etc.

In such cases, an underwater base is installed on the seabed with an anchor, concrete foundation, etc., one end of the chain is fixed to this underwater base, and the other end is fixed to a buoy floating on the sea surface. A method of mooring a buoy of a mooring device and a ship by passing a rope or the like to the mooring device is taken.

As mentioned above, moored vessels are subject to changes in the direction of the tidal current, changes in the tidal level,
They will be able to move freely around the mooring buoy due to the influence of wind forces.

However, in the past, when supplying electricity, water, etc. to a floating ship at anchor, a supply cable was laid on the seabed from the supply side installed on land to the ship's mooring position. Since the cable was simply raised at the ship's mooring position and introduced into the ship, there was a drawback that the cable could become entangled with the chain of the mooring device, leading to a large possibility of an accident due to damage to the cable.

The present invention is a novel invention that improves the above-mentioned drawbacks of the conventional art, and its purpose is to provide a device that can safely supply and receive electricity, water, etc. to a ship at anchor with a simple configuration.

Examples will be described in detail below.

FIG. 1 is an explanatory view of the main parts of the supply/receipt device according to the embodiment of the present invention, in which 1 is a mooring device, 2 is an underwater base,
3 is an anchor, 4 is a concrete foundation, 5 is a chain, 6 is a buoy, 7 is a seabed, 8 is a sea surface, 9 is a ship, 10 is a cable or pipe for supplying electricity, water, etc., and 11 is a guide rail. .

The mooring device 1 embeds and fixes the anchor 3 in the water bottom, that is, the seabed 7,
A concrete foundation 4 is applied to this part to form an underwater base 2, one end of a chain 5 is fixed to this underwater base 2, and the other end is fixed to a buoy 6 floating on the water, that is, on the sea 8. Become.

A guide rail is provided around the underwater base 2 of such a mooring device 1, and is wound several times in a spiral manner.

This guide rail 11 has an upper part 11a appropriately supported by an underwater base 2, and a lower part 11b is fixed to a support 11c raised from a concrete foundation 4 by, for example, welding.
This is supported by c.

In this way, the guide rail 11 is provided on the underwater base 2 of the mooring device 1, and the position of the mooring device, that is, the position of this mooring device 1, can be determined from the power, water, etc. supply side installed on land or on another ship. A section 10a in which a supply cable 10 is laid to the position of a ship 9 moored at anchor by the buoy 6, for example, by a rope 6a, and further the cable 10 is raised near the mooring device 1 in the form of a wire ring. The wire-shaped portion 10a is suspended from the guide rail 11 over a range along the guide rail 11, and the cable end 10b connected to the wire-shaped portion 10a is attached to a ship at anchor. 9
This will be introduced in the future.

In the above, the portion 10a made into a Goof wire ring shape
In order to keep the wire shape constant, as shown in FIGS. 2 and 3, a metal fitting 13 is provided with a hole large enough to hold the cable 10, and one side of this metal fitting 13 is provided with a hole large enough to hold the cable 10. A ring 14 through which the guide rail 11 can be passed is fixed by welding or the like via a connecting plate 15, and the top and bottom of the metal fitting 13 are fixed with bolts 1.
Hanging bracket 1 configured to be tightened and fixed with 6 and nut 17
It is better to use 2.

That is, a plurality of these hanging fittings 12 are attached to the guide rail 11 over a length range along the cable guide rail 11, and the upper part of the part 10a is fixed at each pitch of the part 10a formed into a wire loop of the cable 100. It is gripped and fixed with the hanging fitting 12 (by this means, even if the ring-shaped part 10a becomes expandable and retractable when the boat berth 9 moves while anchored, this part 1
This is because the amount of expansion and contraction for each pitch of 0a is approximately constant.

As mentioned above, the cable 10 between the seabed 7 and the ship 9 has a ring-shaped portion 10a, and this portion 10a is connected to the guide rail 11 spirally wound around the underwater base 2 of the mooring device 1. If it is suspended, this part 10a will be attached to the ship 9
When rotating around the buoy 6, the guide rail 11
The ring-shaped portion 10a expands and contracts along the line.

Therefore, by designing the number of times the guide rail 11 is spirally wound around the underwater base 2 in accordance with the rotational range of the ship 9 with respect to the buoy 6, the ring-shaped portion 10a Since the cable follows the rotational movement of the ship 90 in a flexible manner, the length of the cable end 10b connected to this portion 10a can be appropriately adjusted.

For this reason, when power, water, etc. are supplied to the ship 9 at anchor via the cable 10 from a ship anchored at another location or from land, the ship 9 may Even if the cable 10 moves freely around the buoy 5 of the mooring device 1 under the influence of wind force or wind force, the cable 10 is not entangled with the chain 5 of the mooring device 1, so a safe state is always maintained.

Of course, the same applies in the vicinity of a shipping vessel anchored at anchor.

As explained above, the present invention provides a spirally wound guide rail at the underwater base of the mooring device, and suspends the supply cable in the form of a wire loop over the length range along the guide rail. Therefore, the supply cable near the vessel moored to the buoy of the mooring device will be adjusted to expand and contract according to the movement of the vessel. It can prevent entanglement.

Therefore, according to the supply/receipt device of the present invention, electric power.

This makes it possible to safely supply and receive water, etc., making it extremely effective for industrial use.
