Description
【発明の詳細な説明】 本発明は魚介類等の養殖装置の改良に関する。[Detailed description of the invention] TECHNICAL FIELD The present invention relates to improvements in aquaculture equipment for fish and shellfish.
魚介類を養殖する養殖装置は養殖網の上部に設
けた保持枠によつて海面に浮揚保持しているのが
現状であるが、保持枠には波浪により各方向から
不規則な外力が作用し、特に捻力は強度を著しく
低下せしめ、養殖装置を長期に亘り安定して保持
することができない欠陥があり、その傾向は波浪
の大きい外洋養殖では一層顕著である。 Currently, aquaculture equipment for cultivating fish and shellfish is kept floating on the sea surface by a holding frame installed above the aquaculture net, but irregular external forces act on the holding frame from various directions due to waves. In particular, twisting force significantly reduces the strength, making it impossible to stably hold the aquaculture equipment for a long period of time, and this tendency is even more pronounced in open ocean aquaculture where waves are large.
このため養殖装置を浮沈自在に形成することも
知られているが、台風等の荒天時は別として、通
常の一寸した波浪の度毎に養殖装置を沈降させる
ことは労力的に極めて面倒である。 For this reason, it is known that aquaculture equipment can be made to float and sink, but apart from during stormy weather such as typhoons, it is extremely labor-intensive to sink the aquaculture equipment every time there is a slight wave. .
本発明はこれらの現状に鑑み、極めて簡易な構

ある。 In view of these current circumstances, the present invention is designed to improve the strength of aquaculture equipment with an extremely simple configuration.The present invention is designed to improve the strength of aquaculture equipment with an extremely simple configuration. A top float is provided on the upper part of the holding frame, and a float is attached around the lower part, and the float has a water injection pipe and a tip, the lower end of which opens into the inner bottom and the upper end of which protrudes outward and opens upward. The gist is that an air supply pipe is provided which is fixed to the upper part of the holding frame and whose lower end communicates with the interior of the float.

ている。 To explain an embodiment of the present invention with reference to the drawings, a radial rod 3 is attached to the upper part of the aquaculture net 2 provided with the lower sediment 1.
A holding frame 5 formed in a conical or pyramidal shape with an annular rod 4 is attached, and a working table 6 and a top float 7 are provided at the upper end of the holding frame 5, and a lower float 8 is provided at the lower periphery. and a float 9 that can freely sink.

を回復できるように形成されている。 Therefore, the sinkable float 9 is the hollow floating body 1.
0, an inlet/drain pipe 11 whose upper end is open to the outside of the upper part of the hollow floating body 10 and whose lower end is opened to the bottom of the hollow floating body 10, and an air supply pipe 12 whose tip is connected to the upper part of the hollow floating body 10 which is fixed to the workbench 6. Seawater is injected into the hollow floating body 10 from the injection/discharge pipe 11 due to waves, reducing the buoyancy and sinking, and seawater inside the hollow floating body 10 is injected by injecting pressurized air from the air supply pipe 12. It is formed so that it can be discharged through a drain pipe 11 and its buoyancy can be restored.

よつて決定するものである。 In addition, the total buoyancy of the lower float 8 and the floating float 9 is such that the upper end of the aquaculture net 2 can be held at approximately the sea level, and the total buoyancy of the top float 7 and the lower float 8 is determined by the action of the holding frame 5. It is preferable to adjust each platform 6 so that it is held substantially on the water surface, and furthermore, the length of the injection/drainage pipe 11 that protrudes from the hollow floating body 10 depends on the dangerous wave height in the facility sea area and the preliminary buoyancy when floating at the maximum buoyancy. It is up to you to decide.

である。 Since the embodiment of the present invention is constructed as described above, during normal and small waves, the upper part of the aquaculture net 2 is kept floating on the sea surface as shown in Figure 2, and when the weather is rough with large waves, the seawater can float and sink. Water flows into the hollow floating body 10 from the injection and drainage pipe 11 of the float 9 to reduce the buoyancy and sink until the top float 7 of the aquaculture device is located at the sea surface as shown by the chain line in Figure 2. The trachea 12 is connected to a compressor or the like, and pressurized air is forced into the hollow floating body 10, and seawater is discharged from the inlet/outlet pipe 11 to restore buoyancy and float the aquaculture net 2 to the sea surface again.

て好適である優れた特徴を有する。 In the present invention, the holding frame provided on the upper part of the aquaculture net is formed into a conical or pyramidal shape with radial rods and annular rods, so that the holding frame portion which is the contact area of waves is reinforced, and is particularly effective against repeated torsional forces. It has significantly improved strength and can withstand long-term use, and in the event of typhoons or other rough weather, seawater is caused by waves to flow into the floats around the bottom of the holding frame using water pipes, keeping the aquaculture net and holding frame below the water surface. Automatically sinks to prevent damage caused by large destructive waves and waves, and then when the sea surface becomes calm, pressurized air is supplied from the air pipe to quickly and easily refloat the holding frame and aquaculture net. It has excellent characteristics that make it particularly suitable for use as an aquaculture device in the open ocean.
