Abstract

The present invention relates to a buoy used in fish farms, etc. The buoy includes a pair of outer shells (10, 10') and a pair of inner shells (20, 20') located between the outer shells (10, 10'). The pair of outer shells (10, 10') each include an outer skin (12) having a mating surface (11) that is ultrasonically or thermally welded to a corresponding outer shell and a grid reinforcing rib (14) formed in an inner space of the outer skin (12) to open toward the mating surface (11) and to be relatively shallower than the mating surface (11). The pair of inner shells (20, 20') each include an inner skin (22) having a mating surface (21) that is ultrasonically or thermally welded to the corresponding inner shell, a grid reinforcing rib (24) formed in an inner space of the inner skin (22) and opening toward the mating surface (21), and a closing surface (26) formed opposite to the mating surface (21), to which the grid reinforcing rib (14) formed in the inner space of the outer skin (12) is ultrasonically or thermally welded. Therefore, the inner shells (20, 20') are accommodated inside the outer shells (10, 10') and the inner and outer shells are joined together in an integral structure to create a plurality of compartments (C, C'). According to the present invention, the buoy can maintain buoyancy despite being partially damaged by external forces such as waves or ships, and has improved structural strength due to a double-layered structure of the inner and outer shells.

Description

Fishery buoy

The present invention relates to a buoy used in aquaculture, etc. In detail, the inside of the buoy forms a plurality of compartments so that even if some damage occurs due to external force, only the compartment at the damaged part loses buoyancy and the remaining compartments can maintain buoyancy, but 1 A pair of inner shells are double fused to the inside of the pair of outer shells to reinforce structural strength and to stably maintain buoyancy even when damaged.

In general, as a technique for a buoy having a plurality of compartments for the purpose of improving the structural strength of the buoy (also called 'buoy' or 'buoy') itself and maintaining buoyancy in case of damage, Patent Documents 1 to 4, etc. has been disclosed.

Patent Document 1 is an eco-friendly buoy in which a first divided body and a second divided body composed of a compartment divided by a partition wall and a coupling portion on the inner space are integrally formed by thermal fusion.

Patent Document 2 is composed of an inner shell having a buoyancy space formed therein, and an outer shell formed by coating on the outside of the inner shell, and the endothelium is made from seaweed processing by-products and wood flour as raw materials, and the shell is inner Disclosed is an eco-friendly buoy manufacturing method using seaweed formed by coating and drying polyurea on the outside of the body.

In Patent Document 3, even if a crack or breakage occurs on either side of the buoy, water penetrates only a part of the internal compartment, so it is possible to maintain a buoyant state, so it is possible to improve the disadvantage of easily sinking below the water surface, and to extend the service life An eco-friendly buoy is disclosed.

In Patent Document 4, an upper body and a lower body formed by a high-density styropole are formed, a compartment separated by a partition is formed inside them, and a coupling protrusion and a coupling groove are formed on the upper surface of each partition and the edge, and the upper body and the lower body are formed. A buoy for sea culture is disclosed in which a connection ring with a hole in it is formed on both sides of the outer side of the and bonded with an adhesive or the like.

On the other hand, in the conventional buoy having a plurality of compartments described above, in the case of a small size, the ribs (reinforcing ribs or bulkheads) forming the compartment can be formed long to the joint surface of the shell and separated from the mold, but in the case of a large buoy In this case, it is not possible to apply it because the molding technology that can form the ribs for forming the compartment long up to the joint surface of the outer shell has not been developed, and even when the rim of the outer shell and the reinforcing ribs on the inside are buttted to each other and fused to each other, the rim part Although watertightness can be maintained, the number of compartments is small because the number of compartments is small because the internal reinforcing ribs cannot be fused in a completely butted state, or even if they are fused to each other, the left and right shells or between the upper and lower shells communicate with each other. Even at the time of breakage, a considerable amount of water flows into the communicating compartments, thereby causing a situation in which the required minimum buoyancy cannot be maintained.

The pair of outer shells 10 and 10 ′ includes an outer shell 12 having a bonding surface 11 that is ultrasonically or thermally fused with the corresponding outer shell, and a bonding surface 11 in the inner space of the outer shell 12 . Consists of a grid-type reinforcing rib 14 that is opened to the side and formed relatively shallower than the bonding surface 11,

The pair of inner shells 20 and 20 ′ have an endothelium 22 having a bonding surface 21 that is ultrasonically or thermally fused with the corresponding inner shell, and a bonding surface 21 in the inner space of the endothelium 22 . The grid-type reinforcing rib 24 that is open toward the side and the closed surface 26 on which the grid-type reinforcing ribs 14 formed on the opposite side of the bonding surface 21 and formed in the inner space of the outer shell 12 are ultrasonically or thermally fused. The inner shells 20 and 20' are accommodated inside the outer shells 10 and 10' and are joined to become integral with each other to have a plurality of compartments (C, C').

In this embodiment, the compartments (C, C') may be divided into a compartment (C) formed between the bonded outer shell and the inner shell, and a compartment (C') formed in the bonded inner shell, the outer In the compartment (C) formed between the shell and the inner shell, when the outer shell 12 is locally damaged, water flows into the compartment of the damaged area, but water does not enter the rest of the compartment except for the damaged portion, so it is possible to maintain buoyancy, In particular, in the compartment (C') formed in the inner shell, when only the outer shell 12 is damaged, water does not flow in, and water flows only when the inner shell 22 is damaged. (C') can be a means for the final buoyancy maintenance of the buoy (1).

The bonding surface 11 of the outer shells 10 and 10' is formed in the form of an outward-facing flange, so that the fusion area is widened, so that a solid bonding state between the outer shells 10 and 10' can be maintained during ultrasonic or thermal fusion. have.

In this embodiment, the outer shell (10, 10 ') is generally formed in a hemispherical shape, the buoy according to the present invention can be produced in various shapes including a round or oval, as well as a square, in cross-sectional shape from small to large. Of course, the pair of outer shells (10, 10') is produced by a single mold and fused in a butt state.

In this embodiment, the inner shells 20 and 20' are accommodated inside the outer shells 10 and 10', so that direct contact with water is not made, but instead the outer shells 12 of the outer shells 10 and 10' ) As the inner shell 22 of the inner shell 20, 20 is overlapped on the inside, a double shell structure is formed, of course, the inner shell 20, 20 'is the outer shell (10, 10') on the inside By closing the open portion of the formed reinforcing rib 14 to form a compartment (C), by fusion between the inner shell (20, 20'), that is, another, that is, the outer compartment (C) different from the inner It will form a protected compartment (C') on the side.

In addition, in the present embodiment, on the side of the closing surface 26 of the inner shells 20 and 20', a joint rib 26a, which is in contact with the end of the reinforcing rib 14 of the outer shell 10, 10', is slightly protruded. It is formed in a state of being so that it is possible to maintain airtightness during fusion, as well as to improve the bonding strength of the fusion site, and to improve the structural strength of the closed surface 26 itself, that is, to prevent distortion or other deformation. has been

On the other hand, on the left and right sides of the outer shell (10, 10'), the rope binding part 16 made of a ring shape is formed, and the inner shell (20, 20') at a position corresponding to the rope binding part 16 is formed. The groove 27 is formed in the form of an inward depression for penetration of a rope (not shown).

In the accompanying drawings, the surface of the outer shell 12 of the outer shells 10 and 10 is shown to be formed as a flat surface, but the present invention is not limited thereto. It is preferable to apply or coat a paint or the like for prevention.

The buoy 1 for fishing of this embodiment configured as described above is to put a pair of inner shells 20 and 20' in advance and then put them inside a pair of outer shells 10 and 10' and mutually fusion, or the inner shell ( 20 and 20') are first fused to the inside of the outer shells 10 and 10', respectively, and then the inner shells 20 and 20' are bonded to the outer shells 10 and 10' to which the fusion is performed. It can be integrated through the process, and the fusion method can be applied by applying ultrasonic waves in a pressurized state or other thermal fusion method similar to that used in the existing buoy manufacturing method.

The fishing buoy of this embodiment manufactured as described above is made of a double structure of an outer shell and an inner shell, in comparison with the conventional buoy having a compartment only having a plurality of compartments inside the outer shell, and the compartment also includes an outer shell and Since it is formed between the inner shell and inside the inner shell, even if the outer shell (outer shell) is damaged, if the inner shell (inner shell) is not damaged, the compartment inside the inner shell still maintains buoyancy, so the function of the buoy can be stably maintained. The structural strength of the buoy itself is further improved by the double structure of the inner and outer shells and the grid-type reinforcing ribs that form the compartment inside the shell. There are advantages such as

In the above-described embodiment, only a pair of inner shells are located inside the outer shell, but the present invention is not limited thereto, and multiple inner shells are formed inside the outer shell in the same way as a kind of 'Matryoshka doll'. Of course, it can be built-in.
