Description

[Detailed description of the invention] This invention relates to a float for aquaculture, and is an attempt to obtain a float that is most convenient for use in an aquaculture device for fish, etc.

Conventionally, aquaculture equipment used for cultivating kono lobes, etc., uses, for example, a single lobe, with both ends of the lobes fixed, and a glass bulb or heat lamp placed at a certain interval in the middle. In use, a float made of plastic resin foam is attached, and culture receptors are suspended from parent ropes near both ends of the float.

However, in such a device, the float is on the water surface and is swayed by slight wind waves, so that the main lobe itself, which is directly connected to the float, oscillates under the influence of the oscillation of the float. There is a drawback that culture mother cells and spores that are attached to culture receptors or nets may fall off.

In addition, in order to operate a ship to observe the state of aquaculture and to prevent the swaying parent ropes from touching or entangling each other as described above, it is necessary to keep the parent ropes apart by at least the length of the ship. Ta.

Therefore, there are limits to the installation of aquaculture equipment in limited aquaculture areas.

Therefore, as a result of our efforts to eliminate the above-mentioned drawbacks of the aquaculture equipment, we have made it possible to prevent the floats from being directly affected by the parent rope even if they are exposed to wind or waves, and to prevent the parent rope from interfering with the operation of vessels for observation. In order to make the distance between the ropes as narrow as possible, it is possible to solve all the disadvantages of the conventional method by connecting two floats with a metal or synthetic resin pipe and interposing a connecting lobe between the float and the parent rope. I found out.

Although this device has various excellent effects, it has the drawback that the metal and synthetic resin pipes may break due to strong winds and waves.

After further research to improve this drawback, we were able to solve the problem by arranging flexible rods on both sides of the pipes that were installed in parallel, but the two floats were connected by the pipes as described above. Since it is troublesome to do so, the float itself has been improved in this invention.

In other words, the structure of this invention consists of two symmetrical structures that are integrally made of synthetic resin and have an approximately cylindrical outer shape.
The present invention is characterized in that the float body parts are connected to each other at a connecting part between them, and each outer side of the float body parts is formed as an end portion with a rope locking groove.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

1 is an aquaculture float integrally formed of synthetic resin; 2, 2 are two symmetrical float main parts of the aquaculture float 1 having a substantially cylindrical outer shape; 3 is a float main part 2; The float main parts 2, 2 are connected at a constricted connecting part between the two, and a rope locking groove 4 for attaching an additional float is formed.

Reference numerals 5 and 5 denote outer end portions of the float main body portions 2 and 2, which have rope mooring grooves 6 and 6, respectively.

The aquaculture float 1 shown in FIG. 1 is entirely formed of a synthetic resin foam a with a solid internal shape, preferably a foam made of expanded polystyrene or other thermoplastic resin.

Next, the aquaculture float 1 shown in FIG. 2 is made by coating a synthetic resin foam a' with a solid interior with FRP (b). In particular, the foam a' in this case is preferably made of polyolefin resin. and a polystyrene-based resin are at least partially graft-bonded, for example, particles graft-bonded to polyethylene can be obtained by using polyethylene particles as a core, absorbing a styrene monomer into the core, and polymerizing the styrene monomer within the core. Examples include foamed particles (trade name: PIOCELAN, manufactured by Sekisui Kaorupin Kogyo Co., Ltd.), which are obtained by heating and expanding expanded particles obtained by adding a blowing agent to the particles and fusing them together.

Furthermore, the aquaculture float 1 shown in FIG. 3 has a hollow interior C, and is made of vinyl chloride or ABS.

It is preferable to use a blow-molded material made of non-foamed synthetic resin such as polyethylene, polypropylene, or polycarbonate.

In either case, a pipe or rod-shaped core material made of metal or synthetic resin may be inserted inside for reinforcement.

As an example of a preferable size of the aquaculture float 1 of this invention, the total length is 1350 trvn and the float main body 2 is
.

An example of an aquaculture apparatus using the aquaculture float 1 of this invention constructed as described above will be explained with reference to FIG. 4 and subsequent figures.

Float main body parts 2, 2 forming a symmetrical shape of the aquaculture float 1
50 in the rope locking grooves 6, 6 on the outer ends 5, 5.
Connecting ropes 10 each having a length of 0rrvn are fastened.

The aquaculture floats 1 to which the connecting ropes 10 have been fastened are connected in parallel to two parent ropes 20° 20 via the connecting ropes 10 at an interval of 6 m, as shown in FIG.

The vertical distance between the fastening part of the connecting rope 10 and the parent rope 20.20 in this aquaculture float 1 is 30 cr! It is said to be 1.

The length of the parent ropes 20, 20 is 190 m each,
It is fixed to an anchor 40 via a flexible rod 30,
This fastening is done by keeping the main rope 20.2 in a tensioned state so that it does not sag if the main rope 20.20 swings in the middle.
Both ends of 0 are fixed to anchors 40.

In addition, the flexible rod 30 can be made of bamboo and has a diameter of 70 mm, and is connected to the parent ropes 20.20 so as to have approximately the same dimensions as the aquaculture float 1, so that the distance between the parent ropes 20.20 does not become narrow. The above-mentioned connections are tied together with strings 50 made of natural fibers or synthetic fibers.

The distance from the parent rope 20.20 to the anchor 40 is approximately 2
0 m is preferable, and 25 aquaculture floats 1 are arranged in parallel between the flexible rods 30.30, and hanging ropes 60.60 are tied to the parent lobes 20.20 and suspended. The length of the hanging rope 60.60 is 2.5 m, and six shells TO with a diameter of about 10 cm are attached at intervals of about 40 cm as receptors for aquaculture. Spores are attached.

When such an aquaculture device is installed in an aquaculture area, even if the aquaculture float 1 is affected by the strong roundness and is about to be pushed outward from the parent rope 20.20, the parent rope 20. Damage to the float 1 can be prevented by the buffering effect due to the flexibility of the flexible rod 30 connected to the float 20.

Furthermore, since the parent ropes 20.20 are always held at a constant distance by the flexible rod 30, the fact that the parent ropes 20.20 are below the water surface prevents the hanging ropes 60.60 from coming into contact with each other. , or intertwine, so
The parent rope 20.20 has hanging ropes 60.
60 can be fastened and suspended, and furthermore, it is also possible to provide another parent rope in the rope locking groove 4 provided in the connection part 3 between the float main parts 2 and 2 in the aquaculture float 1. , it is suitable for efficient aquaculture in limited water areas because it can be cultivated densely.

In addition, the hanging rope 60.60 with the shell 70 attached is suspended in the water, and as a result, the parent rope 20.20 also sinks further into the water by the length of the connecting ropes 10, 10, and the aquaculture float 1 , vessels such as fishing boats can freely enter and operate between these areas, and there will be no hindrance to observing the aquaculture conditions or harvesting the aquaculture products by pulling the hanging ropes. You can perform the work without being affected.

In particular, the hanging rope 6060 does not transmit the vibration even if the culture float 1 swings, and as a result, culture can be efficiently carried out without the culture mother cells and spores attached to the shells falling off.

The aquaculture float according to this invention, which is used in the above aquaculture device, has two symmetrical float main bodies 2, each having a substantially cylindrical outer shape, which are connected together at a connecting part 3 between the two. It is made of synthetic resin and has a good overall balance, and since it is not connected with pipes etc., it eliminates the manufacturing process of floats, and it is sturdy because the overall integrity is strengthened. and can withstand long-term use.

Also, each outer side of the float main body parts 2, 2 has a rope locking groove 6.
Since the ropes are formed as attached end portions 5, 5, connection of the rope to the aquaculture device is extremely simple, and the aquaculture float can be easily installed in the aquaculture device.

Therefore, the float of this invention is suitable as a float for cultivating Japanese pearl oysters or seaweed, as well as a float for cultivating female oysters.
