Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention eliminates the need to install separate floats and greatly enhances stability by configuring the main part of the cage frame with a rigid pipe. It relates to the taikousu device.

(Prior Art) A sacking device used for aquaculture and capture and storage of seafood in a space surrounded by a net stretched in the sea is one that suspends and supports the net by a frame that floats on the sea surface. There is one that uses a highly rigid iron material together with the float. However, in order for the sausage device using such a frame body to withstand external forces such as waves,
Generally, a frame body having a large bending rigidity is required, and as a result, the plane projected area of the panning device is reduced, and the efficiency of aquaculture or catching and transporting seafood is reduced.

Therefore, in order to eliminate such drawbacks, the applicant has the fifth
The device shown in the figure was proposed in Japanese Utility Model Publication No. 60-2769. In this sausage device, a reinforcing reinforcement layer is buried, and a hollow reinforcing elastic body 1 that produces sufficient buoyancy under gas filling is mutually connected by a rigid bending joint 2 provided with a locking portion of a mooring line 4. It is configured by connecting and forming a frame frame body 3 which is framed in a polygonal shape, and a net 6 is suspended on the frame body 3. Due to its excellent wave-gluing characteristics, this sausage device can follow the wavefront without damage even for comparatively large waves in the open sea, and abnormal deformation of the cage frame against external forces during towing. It has a rigidity that does not exist.

(Problems to be solved by the invention) By the way, in the state of use of the sausage device, it is accompanied by work such as feeding the seafood in the device and observing their growing state. It is usually done on a frame.

However, in the above-mentioned molding device, since the main part of the molding frame is composed of the hollow reinforcing elastic body, it is possible to support the weight of the worker, but it is greatly deformed and various work is performed. In addition, there is a problem that the work is made of, for example, a steel pipe, and a rigid joint that is less affected by waves is used as a scaffold, and the position of the scaffold is limited.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a bait device that is gentle in waves and does not limit the position of the scaffolding and is excellent in stability.

Further, another object of the present invention is a constituent member of the life frame, on the assumption that the life frame itself exhibits sufficient buoyancy without the need to install an independent float. Even if the frame member, the hollow joint, or the like is damaged and water intrudes into the frame member, it is possible to sufficiently prevent the sink frame from sinking.

(Structure of the Invention) In order to achieve this object, in the present invention, a plurality of frame members made of a rigid pipe having a gas chamber divided by partition walls provided in the vicinity of both ends and having outward flanges at both ends. Each end is mainly composed of a reinforced elastic body,
Each hollow joint having rigid outward flanges at both ends is provided with a frame body which is hermetically connected at the flange positions of the both.

(Operation) When an external force caused by waves or the like acts on this life device, the external force mainly exerts a bending moment on the life frame. This bending moment acts on a frame member made of a rigid pipe, which is a main part of the life frame, but the bending moment acting on each frame member connects them to each other and is excellent in flexibility, It is almost absorbed by the deformation of the hollow joint mainly composed of the reinforcing elastic body, and therefore, the rigid pipe is not subjected to an excessive load,
It is possible to build a life-saving device with a large projected area on a plane.
In addition, the motion of the frame member forming the main part of the life frame by waves is much less than that of the conventional device, which facilitates the work on the life frame.

Further, here, each of the frame member and the hollow joint has sufficient buoyancy, so that it is possible to sufficiently float the life frame on the water surface without installing a separate independent float, and also to add the life frame. Since the body has a plurality of spaces that are independent of each other due to the partition provided in the rigid pipe, for example, even if one of these spaces is damaged and water enters the space, the other space is separated. Due to the existence of the above, it is possible to sufficiently prevent the entire sink frame from sinking.

(Embodiment) Hereinafter, a device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a cage device according to the present invention.
Reference numeral 11 denotes a frame member made of a rigid pipe, 12 denotes a joint for connecting these frame members to each other to form a frame frame 13, and 16 denotes a net suspended from the frame frame 13.

As the frame member 11, it is preferable to use a steel pipe having excellent corrosion resistance and strength in consideration of the usage situation, but a lightweight and excellent strength pipe, for example, a plastic pipe material can also be used. Further, the cross-sectional shape of the frame member 11 is excellent in strength in a circular shape, but is not limited to this, and may be a rectangular shape in consideration of workability on a life frame. good. In such a case, since the frame frame itself serves as a scaffold, it is preferable to provide a non-slip or a projection for that purpose on the part serving as a scaffold.

As shown in FIG. 2, flanges 17 are provided on both ends of the frame member 11 in order to facilitate connection with the joint 12.
In the case where the frame member has a cylindrical outer peripheral surface, a work table 18 having a separate planar shape is provided to further facilitate various works on these frame members, and further, the outer shape of the frame member is concerned. If desired, the fence 19 may be provided on the entire frame body, or on an appropriate portion, if necessary.

Further, each frame member 11 includes a gas chamber 21 defined by partition walls 20 provided at least near both ends thereof.

The joint 12 for connecting such frame members to each other is an elastic body made of rubber or a rubber-like elastic material, reinforced with organic or inorganic fibers, preferably cords thereof,
The number of layers and the angle of the elastic body and the reinforcing fiber cords are selected so as to satisfy the requirements of the joint, for example, kinking is less likely to occur, and bending rigidity increases as bending displacement progresses. This allows the overall shape of the frame 13 to be held substantially constant while allowing some movement between the frame members.

The joint 12 is also provided with rigid flanges 23, which are integrally bonded by vulcanization, at both ends thereof.
The frame member 11 is easily connected via the.

To frame the frame body 13 using such frame members and joints, a flange 17 provided at each end of the frame member,
It may be fastened to the rigid flange 23 of the joint 12 with a fastening bolt (not shown) via an appropriate sealing material. As a result, the frame frame 13 is made up of a frame member having independent gas chambers 21 and a joint having spaces that are also independent of each other. However, the whole frame of the flower does not sink. This is very useful because even if the working vessel accidentally damages the joint, the joint can be easily converted.

Further, in order to impart an excessive buoyancy to the frame member 11, a styrofoam float may be provided on the outer periphery thereof, in which case it is preferable to cover the float with a cloth cover to protect the float from damage. .

And, in addition to the net for the original function,
Attach the support columns for the net for preventing seafood from popping out, hooks for assembling and transporting the cage frame, and hooks for locking mooring lines that moor the cage frame.

Next, another embodiment of the device of the present invention will be described with reference to FIGS.

In the embodiment shown in FIG. 3, a bent integral rigid pipe is used as a frame member at the corner of the cage frame 13, and the other parts of the cage frame are different from those of the embodiment shown in FIG. Similarly, a linear frame member is used to form a rectangular flat frame. The cage frame body having a rectangular plane as shown in FIG. 1 and FIG. 3 can be arranged on the water surface with a plurality of cage frames adjacent to each other without a gap, so that feeding to seafood in the cage device is possible. Work can be performed at the same time, improving workability.

In the embodiment shown in FIG. 4, the flanges attached to both ends of the frame member are arranged such that the planes including the flanges are not orthogonal to the axis of the frame member, and in the present embodiment,
It is an octagonal frame. According to this embodiment, a shape suitable for the migratory movement of fish and shellfish can be obtained, so that a sock frame having a shape preferable for its growth can be obtained.

In addition, in any of the above-described embodiments, it is preferable that the frame member having the cylindrical outer surface is provided with a flat plate-shaped work table 18 made of a steel plate, a wooden plate, or a lattice of these plates on its outer peripheral surface. Anti-slip shall be provided on the workbench if necessary. The frame member having a rectangular cross section may be provided with a slip stopper directly in the work area on the outer periphery thereof.

(Effect of the invention) Therefore, according to the present invention, the frame member forming the main part of the frame body is a rigid pipe, and by connecting these frame members to each other with a flexible joint, Since the shake due to the acting waves can be absorbed by the flexible joint, a stable panorama device with less shaking of the frame member itself can be obtained. Therefore, various operations on the frame of the frame become easy.

Further, since the external force acting on the life frame can be absorbed by the joint, there is no problem as in the case where the whole life frame is made of a rigid pipe.

Moreover, here, by forming a frame body composed of a frame member made of a rigid pipe having a gas chamber and a hollow joint airtightly connected to the frame member, buoyancy can be generated in both of them, so that the float Sufficient buoyancy can be imparted to the life frame without using it at all, and a plurality of gas chambers independent of the life frame are defined by the partition wall provided on the frame member, whichever of them is used. Even if the hollow joint is damaged, the volume of water that infiltrates from the damaged part is sufficiently reduced, and the sinking of the life frame is effectively prevented by the buoyancy provided in another independent gas chamber. can do.

In addition, the hollow flexible joint here has sufficient strength because it is mainly composed of a reinforced elastic body reinforced with organic or inorganic fibers, and therefore, the joint has a wavelike structure. Even if a repeated deformation due to is generated, it is not broken.
