JPS58156487A - Live well of small ship - Google Patents

Abstract

PURPOSE:To almost completely discharge water in a live well only with a scupper, by providing a keel floor used as the bottom plate of the live well to the ship inside of a keel and the drain scuppers to a ship bottom plate in the vicinity of the keel floor. CONSTITUTION:A keel floor 4 is provided to the ship inside of a keel 3 to form the bottom plate of a live well 10. Then drain scuppers 7 and suction water scuppers 8 are provided to a ship bottom plate 2, and the scupper 7 is formed to a position approximate to the floor 4 of the plate 2 while the floor 4 in the part formed with said scupper 7 is locally recessed to form recessed parts 9. In this way, the scupper 7 is opened to the lowest position in the well 10.

Description

[Detailed description of the invention] This invention relates to improvements in cages for small vessels.

Conventionally, in small boats made of fiber-reinforced plastic in which the center keel of the bottom of the boat projects downward and a fish cage section is provided in a part of the hull, a scupper for allowing water to enter and exit the fish cage is provided on the bottom of the fish cage. Although it is L or L, in the conventional structure, the scupper for drainage is not installed at the lowest position at the bottom of the fish cage, so the water in the fish cage cannot be completely drained only by the scupper. The lowest point at the bottom of the fish tank is the keel, but it is not possible to install a scupper here due to strength or other reasons, and because the bottom plate on both sides near the keel has a large curvature, a scupper is also installed here. Therefore, the scupper is installed at a fairly high position at the bottom of the cage.

Any remaining water that could not be completely drained with the scupper was pumped out using a bilge pump or manually.

This invention was made to solve these conventional drawbacks, and the scupper is installed at the lowest position at the bottom of the cage so that the water in the cage can be completely drained only by the scupper. be. That is, the present invention provides a fiber-reinforced plastic ship in which the central keel of the bottom of the ship protrudes downward and is provided with a fish tank section in a part of the hull, and a keel floor is provided on the inside of the keel to serve as the bottom plate of the fish tank. A scupper is provided near the boundary between the bottom plate and the bottom plate.

Embodiments of the present invention will be described below with reference to the drawings. 1st
．． In FIG. 2, 1 is a deck, 2 is a boat 1 shell, and 6 is a keel. A keel floor 4 is provided on the inside of the keel 6 to form the bottom plate of a fish tank 10. 5 is the side plate of the fish tank,
6 is a partition wall. The bottom plate 2 is provided with a drainage scupper 7 and a water absorption scupper 8.
is formed on the bottom plate 2 at a position adjacent to the keel floor 4V, and the keel floor 4 in the portion where the scupper 7 is formed is locally formed by four people to form a four part 9. Therefore,
The scupper 7 opens at the lowest position within the cage 10.

6 and 4 show another embodiment of the present invention, in which a keel floor 4 is formed on the inboard side of the keel B, and a keel floor 4 serving as the bottom plate of the fish tank IO is formed, and four local parts 11 are formed on the outboard side of the bottom plate 2. A drainage scupper 7 is provided on the bottom plate 2 at that portion.

Although only one drainage scupper 7 is shown in the drawings, the number of scuppers 7 to be installed may be determined arbitrarily, and they may be installed on both sides of the keel floor.

In the L reporter configuration, all the scuppers 7 are installed at the lowest position in the fish tank 10, so the water in the fish tank 10 can be completely drained only with these scoopers 7, and the remaining water can be removed by a bilge pump etc. It is very convenient because no discharge is required.

As explained above, in this invention, a keel floor that serves as the bottom plate of the fish tank is provided on the inside of the keel, and a scupper for drainage is provided on the bottom plate near the keel floor, and the scupper is installed at the lowest position of the bottom of the fish tank. Therefore, the water in the cage can be completely drained using only the scupper.
