Abstract

PROBLEM TO BE SOLVED: To prevent marine organisms from attaching to a ship's bottom or the like by fully covering the ship's bottom of a small ship, a boat, a yacht or the like with a sheet, the small ship, the boat, yacht or the like having been stored on the land while placed on a trailer or the like, or placed on a floating building slip in a state of the ship's bottom raised from the sea water or the like to prevent the attachment of the marine organism, or marine leisure boats or the like mostly being moored on the sea surface or the like, which causes the attachment of the marine organism to the ship's bottom or the like, the impairing of the sailing performance of the small ship, the boat, the yacht or the like, and the increase of the fuel expense and the excess cost. SOLUTION: A water-proof sheet is shaped corresponding to a ship's bottom, has a size to be projected from a draft line by 10-20 cm, and has plural lifting belts on several places of its edge part. Drain holes are formed on several places corresponding to the ship's bottom, of the waterproof sheet, and rubber water-passing lids with cuts for allowing the water to pass therethrough, are mounted on the drain holes. That is, this ship's bottom protecting cover consists of the waterproof sheet, the lifting belts, the drain holes and the water-passing lids.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bottom protection cover for preventing marine life such as barnacles from adhering to the bottom of boats, boats and yachts, and to propulsors and rudders, etc. It is about.

[0002]

2. Description of the Related Art Conventionally, small ships, boats, yachts and the like have been stored on land on a trailer or the like, or have been mounted on a floating hull to raise the bottom of the vessel from seawater or the like to prevent marine organisms from adhering.

[0003]

The conventional methods have the following drawbacks, respectively. In the case of storage on land with a trailer or the like, a crane device, a moving device and a storage place on land are required, and this cost has become a great economic burden on owners of boats and yachts. B. When stored on the floating boat table and stored on the sea surface, a crane device and the like are necessary, and in the case of stormy weather, there is considerable danger in operation work.

[0004]

For those who enjoy marine leisure, the operating hours of small boats, boats, yachts, etc., during the year are generally very short due to the weather and other circumstances, leisure and vacation. It is believed that there is. Therefore, most of the year, they are on land storage or floating berths or moored at sea level or the like. Most of the marine leisure vessels are moored on the sea surface, etc.As a result, marine life adheres to the bottom of the ship, which significantly reduces the running performance of small ships, boats, yachts, etc., as well as hull maintenance and fuel costs. Extra costs are required. Therefore, the present invention solves the above-mentioned problem by covering the entire bottom of a ship such as a small ship, boat, and yacht with a sheet to prevent marine organisms from attaching.

[0005]

[Function] A water-resistant sheet formed in the shape of the bottom of a ship is attached to the bottom of small ships, boats, yachts, etc., the lifting belt is pulled up, the water inside the waterproof sheet is taken out from the drain holes, and the bottom is covered with a bottom protection cover. Cover and secure the lifting belt to the deck cleats. Seawater and the like remain in the ship bottom protection cover, but the amount of seawater that enters and exits from the drain hole is small due to the water cover. For this reason, marine life such as barnacles cannot live in the bottom protection cover because seawater containing fresh oxygen etc. is not supplied, and it is necessary to prevent marine life from attaching to the bottom, propulsion device, rudder, etc. Can be.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below. (1) Form the waterproof sheet 1 in the shape of the bottom of the ship, and
Hanging belts 3 are provided at a plurality of locations on the edge 2 of the water-resistant sheet 1 so as to have a size of 0 to 20 cm above. (2) Water-draining holes 4 are provided in several places on the bottom of the water-resistant sheet 1 and a rubber-made water-permeable lid 5 is cut into the water-draining holes 4 so that water can pass therethrough. (3) Attach the reinforcing sheet 6 to the part where the propulsion unit and the rudder contact the rear part of the water-resistant sheet 1. A ship bottom protection cover composed of the above-mentioned water-resistant sheet 1, the lifting belt 3, the drain hole 4, the water cover 5 and the reinforcing sheet 6.

The present invention has a structure as described above. When this is used, the bottom protection cover is extended to the bottom of a small boat, boat, yacht or the like using a lifting belt, and the lifting belt is pulled. Wrap the bottom and secure the lifting belt to the deck cleats. When operating a small ship, boat, yacht, or the like, the lifting belt is opened and the bottom protection cover is accommodated in the ship or stored at a mooring pier or the like.

[0008]

The bottom of the hull, such as the propulsion unit and the rudder, is covered with the bottom protection cover, but seawater and the like remain in the hull and bottom protection cover.
Since fresh water is not supplied to the seawater or the like in the bottom protection cover, marine life such as barnacles cannot inhabit, and it is possible to prevent marine life from attaching to the bottom, propulsion device, rudder and the like.
As a result, a. It is possible to greatly reduce the maintenance cost of the ship bottom such as removal of marine life, etc. In addition, the running performance can be maintained, and the fuel efficiency is significantly improved. (I) storing small ships, boats, yachts, etc. on land, or
This eliminates the need for storage on the surface of a sea, etc. on a floating boat, significantly reducing storage and maintenance costs. C. The bottom protective cover is inexpensive and simple in terms of price and usage compared to other storage methods, and the effect remains the same. In addition, the appearance does not become unsightly. As described above, the bottom protection that easily protects the bottom of a ship from marine life with inexpensive equipment without performing large-scale operation work such as storing small ships, boats, yachts, etc. on land or putting on a floating dock. As a cover, this device contributes greatly to the field.
