Description

  The present invention relates to a raft frame of an aquaculture apparatus for aquaculture of fish under water.

  In the space surrounded by the net stretched in the sea, the skein apparatus used for the cultivation and capture of seafood supports the net suspended by a raft frame floating on the sea surface. In order for the aquaculture apparatus using the raft frame to withstand external forces such as waves, a raft frame having a large bending rigidity is generally required.

  It is usual to perform operations such as feeding fish and shellfish in an aquaculture device (hereinafter referred to as “skewer device”) and observing the growth state on a raft frame. However, although the raft frame of the skein apparatus described above can support the weight of the operator, it is easily affected by waves and becomes unstable.

  Moreover, since the rigid joint is used as a scaffold even if the influence of waves is reduced, there is a problem that the position of the scaffold is limited and the work cannot be performed safely.

  Furthermore, since the skein apparatus floats until it is replaced after it is installed in the sea, it is usually corroded by seawater, and it was normal to pull it out of the sea within a few years and replace it with a new skein apparatus. At that time, there is a problem that a lot of time and labor are required for lifting, installation, and maintenance because the weight of the apparatus body is large.

  Further, the conventional skein apparatus cannot be changed in size freely. Therefore, when raising the scale of aquaculture, there has been a problem that it costs more, such as increasing the number of slaughter devices or replacing them with a larger skein device.

  Moreover, in the open seas, which are easily affected by waves, there was no other way than aquaculture to attach a float directly to the net, like floating floats. Therefore, it was difficult to work safely.

  The aquaculture apparatus according to the present invention is a combination of a lightweight ballast tank with a square or polygonal straight section cut to form a square or polygonal apparatus. Therefore, installation and maintenance can be facilitated and the durability is excellent.

  Moreover, since water is put in the ballast tank and used, excellent stability can be secured even when installed on the sea. Thereby, it is possible to prevent a fall accident and to work safely.

  As described above, since a device that combines a ballast tank with a shape obtained by cutting a square or polygonal straight portion is configured, the size of the device can be arbitrarily changed.

  Moreover, since the raft of the present invention uses a lightweight material, it can be easily maintained. Therefore, it can be used as a semi-permanent device.

  In addition, by placing water in the ballast tank, the stability of the aquaculture equipment is born. In addition, since the platform can move freely without being restricted, the number of accidents can be reduced and work can be performed safely.

  In addition, since the basket with a ballast tank of the sacrificial apparatus of the present invention can be used separately, it is possible to disperse and relieve the vibration caused by waves. Therefore, it can be used in the open sea.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing the entire aquaculture apparatus (hereinafter referred to as an apparatus).

  FIG. 2 is a plan view of the entire frame with a ballast tank for aquaculture of the present invention (hereinafter referred to as a frame with a ballast tank), and FIG. 3 is a perspective view of the entire frame with a ballast tank. FIG. 8 is a plan view and a perspective view of a frame with a hook-type ballast tank. A bulwark 19 is arranged on the outer wall on the inner side of the frame frame 16 with each hook type ballast tank, a partition net fixing port 20 is opened in the bulwark 19, and a net is attached thereto for use.

  Further, by providing the deck 22, it is possible to make the work safe and efficient. Furthermore, it is preferable to use a material such as FRP, which is light and excellent in strength, for the key frame 16 with a key ballast tank. By using such a material, maintenance can be facilitated, and this sake apparatus can be used semipermanently.

  And the watertight partition 21 was provided in the inside of the deck 22, and the ballast tank 18 was made. Further, an air tank 17 is installed in the ballast tank 18. In this way, even if an emergency such as the outer wall breaking occurs, it is possible to prevent the frame 16 with the hooked ballast tank from being submerged.

  As shown in the cross-sectional view of the barrel with the ballast tank in FIG. 7, an injection drainage scraper 23 is attached to the upper portion of the deck 22. At the same time, the deck 22 is provided with a non-slip so that the work can be performed safely and easily.

  Furthermore, the frame according to the present invention can be used by separating the frame 16 with each hook-type ballast tank as shown in FIGS. At that time, for example, by disposing a cushioning material such as a discarded tire and connecting the frame frames 16 with ballast tanks to each other, the damage from external factors such as waves is prevented. be able to.

  In addition, as shown in FIG. 5, the size of the apparatus as shown in FIGS. 3 to 5 is obtained by sandwiching the frame frame 24 with a rectangular parallelepiped ballast tank in FIG. Can be arbitrarily changed.

  Similarly to FIG. 4, this can be used as shown in FIG. 6 where it is easily affected by waves such as the open sea.

  Further, not only a square skein apparatus as shown in FIGS. 3 and 5, but also a polygonal skein apparatus as shown in FIG. 12 can be manufactured and used. Also in this polygonal sacrificial device, the size of the sacrificial device as shown in FIG. 12 to FIG. 13 is reduced by sandwiching the cage ball with a cuboid ballast tank between the hooks 16 with the key ballast tank as in FIG. It can be changed arbitrarily.

  Furthermore, by using it as shown in FIG. 14 and FIG. 15, it is possible to cultivate in the open sea that is easily affected by waves.

  In the present invention, a ballast tank is configured in a boat raft frame of an aquaculture device, so that it is not necessary to install an individual float and greatly improve stability. Further, the present invention relates to a raft frame of an apparatus that can be cultivated in the open sea, and that the size of the apparatus that can be cultured can be arbitrarily changed by cutting a square or polygonal straight portion.
