2. Description of the Related Art Conventionally, in the aquaculture industry, a float for floating a cage or a raft for aquaculture on the sea and a marine float using styrofoam as a buoy serving as a mark have been used. The marine float was manufactured by forming a cylindrical Styrofoam molded article and covering the outside thereof with a polypropylene cover in order to prevent the adhesion of marine organisms. In order to attach the marine float to a cage or a raft for aquaculture, the outside is bound with a rope, and the rope is also used to bind to the cage or a raft for aquaculture. Then, when installing it, care was taken not to cut or damage the marine float. Further, the cover is damaged in 6 to 10 months due to natural deterioration such as ultraviolet rays. Therefore, the cover was replaced with a new marine float or the cover was repaired before use. Further, the marine float is replaced with a new marine float when the Styrofoam molded product deteriorates and shrinks after a long period of use, or when the marine float is damaged by external force such as wave force or contact with a ship and causes a decrease in buoyancy. Was there.

[0003]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional marine float, when it is attached to a cage or a raft for aquaculture, it must be done with care because it will cause damage such as cutting if tied too tightly. There was a problem in that it took time. Also, damage caused by natural deterioration of the cover,
Shrinkage due to deterioration of Styrofoam, or easy damage due to wave force or external force such as contact with a ship reduces buoyancy.
There was a problem that the replacement would generate waste. On the other hand, in recent years, plastic bottles (generally called PET bottles) have been used as containers for soy sauce, sauces, etc. instead of glass bottles, and they have relatively sufficient strength, but most of them are discarded or disposed. However, there was also a problem that it was not effectively utilized. The present invention has been made in view of such circumstances, and can effectively use the waste, can be attached to a cage or a raft for aquaculture without any trouble, and can prevent external force such as wave force or contact with a ship. It is an object of the present invention to provide an environmentally friendly marine float that does not easily break when received and does not generate waste.

[0004]

A method according to the above-mentioned object.
The marine float described is configured by filling a plastic or FRP container with sealed bottles made of hard plastic and having a certain shape, and sealing the container. The marine float according to claim 2 is a plastic or FRP container in which sealed bottles made of hard plastic and having a certain shape are put.
The gap is filled with a foam material. Here, FRP means fiber reinforced plastic, for example,
There are laminated plates of epoxy resin, unsaturated polyester resin and glass fiber.

[0005]

In the marine float according to claim 1, since the sealed bottles made of hard plastic and having a certain shape are filled in the container of the plastic or FRP and sealed, the waste is effectively used. Can be promoted. Further, when the marine float is used for buoyancy such as a cage or a raft for aquaculture, the outer side is formed by the container, so that the marine float will not be damaged even if strongly tied to the aquaculture raft or the like, and further wave It is possible to prevent the generation of wastes without being easily damaged even if it receives an impact such as the above, or an external force such as contact with a ship. Further, even if damage such as cracks occurs, the bottles have a buoyancy uniquely and have a certain amount of buoyancy, so that the cage and the raft for aquaculture do not sink. In the marine float according to claim 2,
Since the gaps between the bottles are filled with a foam material and stored in a plastic or FRP container, the internal bottles and the foam material filled in these gaps also have strength and are strong as a whole. Become a float. Further, it can be used in the same manner as the marine float according to claim 1, and even if the outer container is lost, the gap between the inner bottles is filled with a foam material, so that the bottles are Will not fall apart and will not flow out.

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is a perspective view of a marine float according to an embodiment of the present invention, FIG. 2 is a partial sectional view of the marine float, and FIG. 3 is a front view of a plastic bottle. As shown in FIGS. 1 and 2, a marine float 10 according to an embodiment of the present invention has a buoyant body 13 including an outer substantially cylindrical storage container 11 and a number of plastic containers 12 inside thereof. Have and. These will be described in detail below. And
The storage container 11 is composed of half-divided containers 14 and 15 which are divided into two parts, and flange portions 16 and 17 having a belt-like thickness are formed on the peripheral edges of the respective half-divided containers 14 and 15.
A swelling portion 19 having a substantially square shape and having a through hole 18 is continuously provided in 7, and the flange portions 16 and 17 are joined to each other to form a mounting hole through which a rope or the like is passed. .

Next, a method of manufacturing the marine float 10 will be described. First, the half-divided containers 14 and 15 that form the storage container 11 are manufactured by molding them in a predetermined mold using FRP and applying a weather resistant coating on the outside thereof. Regarding the buoyant body 13, FIGS.
First, in order to effectively use the waste, a large number of empty plastic containers 12 for storing soy sauce and the like are prepared. First, all of these mouths are closed with stoppers, caps, etc., and then stored. The number of the plastic containers 12 that substantially fills the cross section of the container 11 is tied with the string 20, and three sets of the tied plastic containers 12 are prepared. Then, three sets of the plastic containers 12 bound by the string 20 are arranged in parallel and housed in a molding mold having the same shape and volume as the inside of the storage container 11, and the space inside the mold is made of polyurethane, The storage container 11 is foamed and integrated so as to have the same shape as the internal shape. Then, the buoyant body 13 is housed in one half-divided container 14, and then an adhesive is applied to the flange portions 16 and 17 of the half-divided containers 14 and 15, respectively, to form the flange portions of the half-divided containers 14 and 15. 16 and 17 are joined. The buoyancy body 13 is tightly sealed inside the storage container 11 by the joining. By this, even if a force is applied from the outside, the buoyancy body 13 inside also takes the force. Since the storage container 11 stores the plastic container 12 as a waste therein for use, it contributes to environmental protection and can be manufactured at a low cost.

The plastic container 12 to be stored in the storage container 11 may be any one that can be closed by a lid or the like provided on itself, and may be, for example, a plastic container for juice as waste. The number of plastic containers 12 to be stored in the storage container 11 is determined in consideration of the size of the storage container 11 so that the gap is as small as possible. Further, although polyurethane is used as the foaming material, other foaming material such as polystyrene may be used, or the plastic container 12 bound with the string 20 may be simply placed in the storage container 11 without using the foaming material. It may be stored.

Next, a method of using the marine float 10 according to one embodiment of the present invention will be described. The marine float 10 is used for a buoy, a cage, a raft for aquaculture, or the like that requires buoyancy. Here, a case where the marine float 10 is attached to a raft for aquaculture for use will be described. A plurality of marine floats 10 are arranged at predetermined positions on the aquaculture raft, and a rope or the like is passed through the through hole 18 of the storage container 11 to tie the marine float 10 to the aquaculture raft. At this time, ocean float 10
Since the outside is the storage container 11 formed of FRP, it is also possible to pass a rope or the like through the through hole 18 to tightly bind the outside of the storage container 11 and bind it to the raft for aquaculture. Since the storage container 11 of the marine float 10 is strong, it does not become a waste due to damage when it is attached to the raft for aquaculture, and it does not become a waste due to the rope or the like being loosened and drifting.
In addition, the marine float 10 attached to the raft for aquaculture,
Although the FRP is strong and is filled with the buoyant body 13, the FRP is not easily damaged and is not a waste although it receives an impact of waves or an external force such as contact with a ship. Even if damage such as cracking or chipping occurs, the plastic container 12 inside is sealed by the lid and connected to each other by the foam material, so that the buoyancy of the ocean float does not decrease, The plastic container 12 does not flow out. Furthermore, since the storage container 11 is formed of FRP and the weatherproof coating is applied to the outside thereof, it is resistant to natural deterioration and can withstand long-term use.

Although the storage container 11 is formed of FRP, it may be formed of plastic. In the formation of the buoyant body 13, the storage container 11 is provided in a predetermined pressure case, the plastic container 12 is stored, and foam is generated in the storage container 11 by using a foam material to fill the gap between them. May be.

[0011]

In the marine float according to the first aspect of the present invention, since the plastic or FRP container is filled with the sealed bottles made of hard plastic and having a certain shape, the waste is effectively used. Can be promoted. Further, the ocean float is formed by the container on the outside, and since the inside is filled with bottles, it will not be damaged even if it is strongly tied to the raft for aquaculture, etc. Even if it receives an external force such as contact with a ship, it is not easily damaged and the generation of waste can be prevented. Further, since the bottles have buoyancy independently, the buoyancy does not decrease even if the container is damaged such as cracked. The marine float according to claim 2 has the same effects as those of the marine float according to claim 1 because the bottles filled with the gaps are filled with a foam material and housed in a plastic or FRP container. Even if the outer container is damaged, the gap between the inner bottles is filled with the foam material, so that it is possible to prevent pollution caused by the bottles flowing out of the bottles.
