DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boat mooring method and device, and more particularly to a boat mooring method and device for preventing aquatic organisms such as a barnacle from adhering to the bottom of a mooring boat.

[0002]

2. Description of the Related Art Conventionally, as a means for preventing underwater creatures such as barnacles from adhering to the bottom of a berthed or moored ship, a method of painting a toxic bottom paint on the bottom of a ship, and applying an electric current to a moored hull. Methods and the like are generally known. However, each of the conventional means for preventing the attachment of aquatic organisms has a problem in that it is expensive and a problem in terms of pollution, and in particular, it is not suitable for leisure boats.

[0003]

SUMMARY OF THE INVENTION The present invention seeks to provide an inexpensive, pollution-free means suitable for preventing underwater organisms from adhering to the bottom of a leisure boat, especially during mooring. Things.

[0004]

According to the boat mooring method of the present invention, a box-shaped tarpaulin is floated on the mooring place of the boat by a float, and the boat is housed in an isolated water area surrounded by the box-shaped tarpaulin. It is characterized by mooring.

Preferably, a float is provided along the upper edge of the box-shaped waterproof sheet, and one end of the box-shaped waterproof sheet is opened while the box-shaped waterproof sheet is connected to the mooring pile with a rope. After the boat is introduced into the box-shaped prevention sheet from this open end, the one end of the box-shaped waterproof sheet is substantially vertically bent, and the bent end portion is folded and fixed, thereby being surrounded by the box-shaped waterproof sheet. The isolated water area is isolated from the external water area and the boat is moored in this isolated water area.

Further, the boat mooring device according to the present invention comprises a box-shaped waterproof sheet, a float provided along an upper edge of the box-shaped waterproof sheet, and a rope for connecting the box-shaped waterproof sheet to the mooring pile. It is characterized by having.

In this device, in addition to the above, at least one end of the box-shaped waterproof sheet is formed so as to be openable and foldable, and the foldable closing portion is fixed at the folding position. A detachable connection tool is provided.

[0008]

According to the present invention, the bottom of the boat is surrounded by the waterproof sheet at the boat mooring place, and the mooring boat is held in the isolated water area isolated from the external water area. The living conditions of aquatic organisms,
For example, the conditions for oxygen content in water, water temperature, etc. become extremely poor, and in the isolated water area, it becomes impossible for the bottoms such as Fujitsubo and Eboshigai to survive. Can be effectively prevented. Here, when a small amount of an aquatic organism attachment-preventing agent, which can be, for example, a neutral detergent, is injected into the isolated water area, the living condition of the organism in the water area can be deteriorated earlier.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 shows a state where a boat 2 is moored at a predetermined mooring place using a mooring device 1 according to the present invention.

A boat mooring apparatus 1 shown in FIG. 1 includes a boat-shaped waterproof sheet 4 in which a waterproof sheet coated on one or both sides with a vinyl coating is formed in a boat shape. A float 5 is attached and is anchored to the mooring piles 3 at a predetermined boat mooring place by rings 7 provided at the ends of mooring ropes 6 mounted at least at four points on the upper edge of the boat-shaped waterproof sheet 4.

In this manner, the boat 2 is accommodated in the water area 8 surrounded by the boat-shaped waterproof sheet 4 anchored at a predetermined boat anchoring place.

As shown in an exploded plan view of FIG. 2, the boat-shaped waterproof sheet 4 has a tapered front portion 4b having an inclined side edge 4a inclined with respect to the center line C in a developed state, and a tapered front portion 4b with respect to the center line C. It has a rectangular rear portion 4e having parallel side edges 4c and rear end edges 4d extending in parallel, and a triangular notch portion 4f in which the front end of the tapered front portion 4b is notched. The angle α formed by both sides 4g and 4h of the triangular cutout portion 4f is preferably 90 to 120 °.

The ship-shaped waterproof sheet 4 is formed by bonding both sides 4g, 4h of the cutout portion 4f of the developed waterproof sheet shown in FIG. 2 to each other by heat sealing and folding and closing the rear portion as will be described later. .

The side edge 4a and the side edge of the boat-shaped waterproof sheet 4
The float 5 provided along the 4c can be formed by a cylindrical foam polystyrene, and the side edges 4a and 4c are folded to form an airtight air chamber, and air is pushed into the airtight chamber by a hand push or a foot pump. By injecting, the float 5 can be provided along the inclined side edge 4a and the parallel side edge 4c.

As described above, the boat-shaped waterproof sheet 4 has the tapered front portion 4b and the rectangular rear portion 4e, and the both sides 4g and 4h of the front notch portion 4f of the tapered front portion 4b are bonded.
A float 5 is provided along the inclined side edge 4a and the parallel side edge 4c of the boat to spread the boat-shaped tarpaulin 4 above the water at the boat mooring place, and as a result, the upper edge of each side edge 4a and 4c at an appropriate position. The rope 6 attached to the boat is connected to the mooring pile 3, and the boat-shaped tarpaulin 4 is floated and anchored at a predetermined boat mooring place as shown in FIGS. 3 (a) and 4 (a).

As described above, the boat-shaped waterproof sheet 4 floated at a predetermined boat mooring place has its rear end 4d immersed in water and opened to the rear. Therefore, after the boat 2 to be moored is made to enter the water area surrounded by the boat-shaped waterproof sheet 4 in the direction of arrow A, the boat 2 is fixed as shown in FIGS. 3 (b) and 4 (b).
As shown in FIG. 2, the rear portion 4e is bent along the fold line a in FIG.

Further, fold lines b, c and d shown in FIG.
3 (c), 4 (c) and FIGS. 5, 6 (a) and 6 (b) by fixing the folded portion in a folded state with a suitable connecting member 10 such as a detachable connecting bolt or rope. Close the rear end as shown in. Thus, an isolated water area 8 surrounded by the waterproof sheet 4 is provided around the bottom of the boat 2, and water in the water area 8 is supplied to the external water area.
Complete isolation from 10. Here, in this isolated water area,
As described above, since the organisms attached to the bottom of the ship cannot substantially survive, the risk of the organisms attaching to the bottom of the ship is sufficiently removed.

By the way, under such mooring state of the boat 2, the waterproof sheet 4 is connected to the boat 2 by a plurality of ropes (not shown) attached to the upper side edges 4a, 4c of the boat-shaped waterproof sheet 4 if necessary. Alternatively, the boat 2 can be moored to the mooring pile 3 by a mooring rope (not shown).

Although the embodiment in which the waterproof sheet 4 has a boat shape has been described above, the shape thereof may be a rectangular dish shape or other suitable box shape.

[0020]

According to the present invention, a boat is housed in an isolated water area surrounded by a box-shaped waterproof sheet, and it is possible to substantially prevent the survival of organisms attached to the bottom of the boat in the water area.
It is possible to prevent aquatic organisms from adhering to the bottom of the moored boat at low cost.
