JPH0612290U - Bottom protection sheet for ships - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to easily prevent the adhesion of underwater suspended matter (Fujitsubo, etc.) to the underwater hull of a moored moored ship. [Structure] A water resistant or mesh sheet 1 formed on the lower surface of the ship is formed, and a suitable number of weights 4 for preventing the sheet from floating up and a large number of attachment means 5, 6 for fixing to the ship. And a drainage port 8 with a check valve.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the protection of ships, such as boats and yachts, that are connected to harbors.

[0002]

[Prior art]

 Conventionally, boats and yachts, which are kept in a yacht harbor, etc., are regularly raised to the ground to clean the underside of the hull when the ship is stopped for a long period of time. This is to prevent floating substances in the seawater, such as Fujitsubo, from adhering to the hull, and to maintain the cleanliness of the hull. However, in the case of a relatively short period of time, it takes a lot of time and equipment to pull it up to the ground one by one, and the hull is currently stored in a tethered ship. Floating materials (Fujitsubo etc.) immediately adhere to the underside of the hull and damage the hull. Therefore, this adhered material must be removed regularly.

[0003]

[Problems to be solved by the device]

 As mentioned above, while the ship is moored, underwater suspended matter (Fujitsuka etc.) adheres to the underside of the hull, so it is necessary to clean it. There is a problem. In view of these problems, the present invention has an object to easily prevent adherence of suspended solids in water to the hull of a moored yacht, boat or the like, and to enable repeated use. .

[0004]

[Means for Solving the Problems]

 In order to achieve the above purpose, a water-resistant and touch-resistant sheet that covers the entire bottom surface of a ship such as a yacht or a boat should be provided, and this sheet should be wrapped around the entire bottom surface of the ship that is moored. The cover is used to block water from the hull and to prevent floating substances (such as Fujitsubo) in seawater from directly adhering to the hull. The seat is made of vinyl chloride material or a thin mesh sheet material, and a rope for attaching to the hull and a drainage port with a check valve are installed on this sheet, and the seat easily settles under the seat. Install a weight to do this.

[0005]

[Action]

 Spread the sheet formed along the lower surface of the ship and bring the sheet backward or forward while letting it settle down from the front or back of the ship to cover the lower surface of the ship. In this way, with the rope attached to the seat covering the entire bottom surface of the ship, the seat is fixed to the hull with the upper end of the seat raised above the water surface. At this time, the water that has entered between the inner surface of the seat and the hull is drained to the outside from the several drain ports with check valves provided on the seat when the seat end is lifted above the water surface. Makes it easier to lift.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which the lower surface protective sheet for a ship of the present invention is expanded. Is an insertion port of a push sill 3 with a hook provided at the front and rear of the upper end of the seat 1 and an intermediate portion thereof. The push rod with hook 3 should be brought to the rear or the front while sinking below the surface of the water to cover the bottom of the boat, and the push rod with hook 3 should be pulled out from the insertion port 2 when the bottom face of the boat is covered. Reference numeral 4 denotes several weights provided below the seat 1 to prevent the seat 1 from floating when covering the seat 1 and make it easier to settle. Reference numeral 5 denotes the seat 1 on the entire lower surface of the ship. A plurality of ropes 6 are provided at intervals in the seat 1 for covering and fixing and for lifting the end of the seat above the water surface.

FIG. 2 is a cross-sectional view showing a state in which the lower surface of the ship is covered with the seat 1 and fixed to the ship, and several ropes attached to the seat 1 with the seat 1 covering the entire lower surface of the ship 7 Squeeze 5 to fix the end of the seat 1 to the ship 7 in a state of being raised above the water surface. At this time, some water enters between the seat 1 and the hull of the ship, and it is difficult to lift the end of the seat 1 to the surface of the water, so there are several non-corrosive check valves for drainage. Install drainage port 8. This prevents the internal water from being discharged to the outside and prevents the external water from entering the inside, and makes it easy to raise the end of the sheet 1 above the water surface. FIG. 3 is a cross-sectional view of FIG. 2, and 9 is a fender installed on both sides of the rope in order to prevent the outer surface of the ship from being damaged by the rope 5. The fender 9 has a role of preventing the rope 5 from sinking when the seat 1 covers the lower surface of the ship.

[0008]

[Effect of device]

 As described above, the present invention is provided with a sheet trimming the lower surface of the ship so as to cover the entire lower surface of the ship. As a result, the hull below the sea surface is shielded from the sea water, so that the adherence and damage of sea water suspended matter, such as Fujitsubo, can be prevented, and the hull can be kept clean for a long period of time. The sheet can be saved significantly, and since this sheet can be used repeatedly every mooring, it can protect the hull well and greatly extend the period of time required for repainting, making it extremely economical and practical. It is rich.
