Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a floating-sink type aquaculture device used for aquaculture of fish, shellfish, seaweed and the like on the sea surface.

[Conventional technology]

Conventionally, as floating-sink type aquaculture devices, those described in JP-A-52-14197, JP-A-57-17491 and JP-A-63-309123 are known.

Thus, the one described in JP-A-52-14197 has a cage net suspended in the inner space of a frame-shaped floating body having a buoyancy adjusting chamber, and by adjusting the amount of seawater in the buoyancy adjusting chamber,
The floating and sinking body is characterized by ascending and sinking, and the sinking stops when the balancer reaches the bottom of the sea. In addition, the one described in JP-A-57-17491 has a filling control of the fuselage main body. A possible buoyancy controller is provided to balance the underwater weight of the underwater buoyancy body with the body of the cage and the mooring line to control the sinking speed and depth of the cage body.

Generally, when a cage is floating on the surface of the water, it is stable due to buoyancy, but when it is submerged in water, it loses its stability and its posture becomes unstable.

Therefore, in order to always keep the posture of the cage stable, the cage frame has appropriate rigidity and maintains a predetermined position in the vertical direction (depth direction) and the horizontal direction, and the cage frame should not tilt. Some kind of restraint needs to be made.

However, in the above-mentioned device, the body of the chair has a buoyancy adjusting function, and if the chair is a square type,
Normally, it is necessary to give the buoyancy adjusting function to each of the four corners of the cage, so that the buoyancy of the four cages is made equal by using a communication tube to prevent the cage frame from tilting. Since it has the buoyancy adjusting function, the common problem is that if the buoyancy adjusting function is broken even in one place, the cask will lose its stability.

On the other hand, the one described in Japanese Patent Laid-Open No. 63-309123 proposes a float-sink type aquaculture device which does not have the above-mentioned problems, and is a buoyant frame having a buoyancy provided with a plurality of rope supporting fittings. The floater and sinker are placed inside, and one or more mooring lines are passed through the rope support fittings, one end is fixed to the anchor and the other end is fixed to the floater and sinker, and the weight or buoyancy of the floater and sinker is changed to When the mooring line slides in the rope supporting metal part, the cage frame floats or sinks while the rope is sunk or floated.

[Problems to be Solved by the Invention]

However, even in the above-mentioned device, when the cage is floating on the surface of the water, it is stable due to buoyancy, but when it is submerged in the water, it loses its stability and often cannot maintain its normal posture.

That is, as shown in Fig. 12, it is desirable for the skein to maintain a horizontal posture even in water, but due to unstable behavior,
As shown in Fig. 13, the cage is often tilted and stable in its original state.

The inclination of the cage in water in such a floating-type aquaculture apparatus causes a decrease in aquaculture area and aquaculture volume, which causes a problem that efficiency of aquaculture business is deteriorated.

Therefore, the problem to be solved by the present invention is to provide a floating-sink type aquaculture device having a function of being able to restore by itself even if the cage is tilted in water.

The present invention has been made for the purpose of solving the above-mentioned problems, and the structure thereof is such that a floating buoyant body guide having rigidity is provided at a central portion of a cage frame having buoyancy through a support beam attached to the cage frame. It is provided vertically, and a rope supporting member is arranged on the frame, etc., and a plurality of mooring ropes are fixed to the anchor at one end through the rope supporting member and the other end is fixed to the floating body set in the floating body guide. Or the floating body is fixed to the cage frame or the floating body guide, and the weight or buoyancy of the floating body is changed to sink or float the floating body in the guide and to moor the rope at the rope supporting member. It is characterized in that it is slid so that the living frame can float up and down.

That is, the float-sink type aquaculture device of the present invention is provided with a rigid float-sink body guide vertically at the center of the cage frame so that the float-sink body floats and sinks in the float-sink body guide. By the action of the body and its guide, the tilt of the frame is corrected so that the frame is always horizontal,
It enabled efficient aquaculture work.

[Operation of the invention]

Since the floating body is settled up and down by the rigid guide provided in the central part of the frame, the floating frame can be corrected by itself even if the frame tilts, and the frame can be stabilized horizontally.
