Description

  The present invention relates to aquaculture trough used for aquaculture of fish, shellfish, and seafood, and more particularly to a large aquaculture trough corresponding to the open ocean that receives large wave force, tidal current force, and mooring force in the open ocean area.

  Cultured fish is a method of culturing fish, shellfish, and seafood such as algae in an aquaculture net that is suspended and supported by a frame that floats on the water. In recent years, it has been proposed that cultured sesame be used in the open ocean outside the bay due to the large size of cultured fish and the contamination of seawater in the bay. The shape of the frame that is made of steel is maintained, but in the open ocean area, it receives a large wave force, tidal force, mooring force, for example, when receiving a large force due to waves, If the rigidity of the skein frame is large, the skein frame may be deformed flexibly and cannot absorb the force, which may cause damage. For this reason, it is conceivable to increase the cross section to withstand such a large force, but it is not realistic because the steel weight becomes heavier and the rigidity is further increased, so that a greater force is received. It was. In addition, some proposals have been made to connect a frame member that constitutes a frame through a joint using an elastic body made of a rubber-based material (see, for example, Patent Documents 1, 2, and 3).

  The skeins described in Patent Document 1 have L-shaped attachment plates fixed to the ends of the skein frame members, and both sides of the plate-like elastic body are attached to the attachment plates of two neighboring skein frame members. A frame member is connected. As a result, the elastic body tries to prevent the frame from being damaged by absorbing a large wave force, tidal force, and mooring force.

  The skeins described in Patent Document 2 connect a straight member, which is a skein frame member, with a flexible joint rubber formed in an arc shape with the center of a cylindrical upper and lower wall having a square cross section facing inward. By fastening the end of the linear member and the side wall of the flexible joint rubber with bolts and nuts with the end faces of two adjacent linear members in contact with both side walls of the flexible joint rubber, the flexible joint rubber Linear members are connected. As a result, the flexible joint rubber is intended to prevent damage to the frame that can absorb large wave force, tidal current force, and mooring force.

  The skein described in Patent Document 3 is to connect a skein frame member made of a rigid pipe with an elastic body made of rubber or a rubber-like elastic material. The frame member is connected via the elastic body by providing flanges at the ends of the frame member and providing rigid flanges at both ends of the elastic body and fastening the flanges with bolts and nuts. As a result, the elastic body tries to prevent the frame from being damaged by absorbing a large wave force, tidal force, and mooring force.

  By the way, in the case described in Patent Document 1, since the plate-like elastic body is attached in a state parallel to the plane in which the frame member extends, the portion where the two piece frame members are connected by the elastic body. Then, when the connecting direction is the axial direction, the force in the axial direction and the horizontal direction can be absorbed by the elastic body, but the two squeeze frame members that are difficult to absorb the force in the vertical direction by the elastic body are located on the elastic body. It bends more than necessary at the center. As a result, when the skeleton is assembled on the ground and lifted by a crane and moved to the sea, or when a large force is applied in the vertical direction at the sea, the shape of the skeleton is not maintained, but the skeleton may be broken.

  In the case described in Patent Document 2, when a frame member is connected with a cylindrical flexible joint rubber having a square cross section, a contact plate is brought into contact with the inner surface of the side wall of the flexible joint rubber so that the inside of the flexible joint rubber can be used. The bolt is passed through the plate, the side wall of the flexible joint rubber, and the end of the member, and a nut is screwed onto the tip of the bolt. The bolt and the nut are not one for each member, for example 4 Therefore, it is difficult to work especially at the center side of the flexible joint rubber, and the flexible joint rubber, that is, the fitting cannot be easily attached. Note that the ends of the two sway members connected by the flexible joint rubber are further connected by a tension rod. The tension rod passes through the end of one skein member, the end of the flexible joint rubber and the other skein member, cushion rubber is fitted around the tension rod in the flexible joint rubber, and both sides of the tension rod The cushion rubber, the washer, and the nut are respectively attached to the flexible joint rubber sequentially from the flexible joint rubber side, and the allowable range that can be deformed in the connecting direction of the flexible joint rubber is limited. For this reason, in order to connect the ends of two squeeze members with a flexible joint rubber, that is, a joint, the tension rod must be attached, and the joint cannot be easily attached.

  In the case described in Patent Document 3, the elastic body is connected to the ends of the frame member where the rigid flanges are provided at both ends of the elastic body, but the rigid flanges are bonded to both ends of the elastic body by vulcanization. In this case, a large wave force, tidal current force, and mooring force repeatedly act in the open ocean area, so that the rigid flange may be peeled off from the elastic body during bonding. As a result, Ikei cannot be used in the open ocean for a long time.

  In addition, with conventional skeins that have been connected to these frame members through elastic bodies, elastic joints are generally too soft in an attempt to make skeins flexible, resulting in horizontal forces due to wave, tidal and mooring forces. On the other hand, there is an accident in which the elastic joint is bent suddenly and the plane shape of the sausage cannot be maintained. Even if the elastic joint is too soft, if it receives a force in the vertical direction (vertical direction) due to wave force, tidal force, mooring force, even if it is temporarily bent largely in the vertical direction by the elastic joint, Ikebana on the surface of the sea always receives buoyancy and is restored to its original shape. However, an accident that keeps the shape of the skein in the horizontal plane is a fatal problem because it reduces the aquaculture area for a long time.

  The problem to be solved by the present invention is that the cultivated skeleton frame has a rigid frame member connected by an elastic joint, and the shape of the frame can be maintained while being flexible. It is intended to be easy and can be used in the open ocean for a long time.

  In order to solve the above problems, the cultured sushi according to the present invention is a cultivated sushi that cultivates seafood in an aquaculture net suspended and supported by a skein that floats on the water. A plurality of high-rigidity tubular skeletal frame members provided with annular flanges at both ends and connected endlessly with elastic joints, the elastic joints facing each other between two adjacent skeletal frame members Natural rubber and synthetic rubber, which are provided between the flanges, and have a first surface and a second surface that are in surface contact with each other in the entire circumferential direction of the surfaces of these two flanges, and absorb and contract the force acting on the frame A plurality of elastic bodies made of synthetic resin or a mixture thereof, and a plurality of elastic bodies disposed on the elastic bodies to fix the first and second surfaces of the elastic bodies to the entire circumferential direction of the surfaces of the two flanges. One side A first mounting member embedded in the elastic body so that the elastic body extends when a force is applied in the pulling direction, the other projecting from the first surface and the second surface and penetrating the two flanges And a second mounting member, a connecting member embedded in the elastic body and movably connecting the first mounting member and the second mounting member, respectively, the first mounting member protruding from the two flanges, and And a fixing member that is mounted on each of the second mounting members and fixes the elastic body while being sandwiched between the two flanges.

In this manner, the first mounting member and the second mounting member of the elastic body are protruded from the flanges of the two skeletal frame members, respectively, and the fixing members are mounted on the first mounting member and the second mounting member, respectively, The body is fixed in a state of being sandwiched between two flanges, and the two skeletal frame members are connected by an elastic joint. Therefore, the frame member can be easily connected by the elastic joint.
Moreover, since the 1st attachment member and 2nd attachment member for fixing an elastic body are embed | buried under the elastic body integrally, even if it uses it for a long time in an open sea area, the connection of the frame member by an elastic joint is hold | maintained can do.
Further, the elastic body has the first surface and the second surface in contact with the entire circumferential direction of the flanges of the two squeeze frame members, and the first surface of the elastic body with the entire circumferential direction of the surfaces of the two flanges. Since a plurality of first mounting members and second mounting members are provided to fix the second surface, the axial direction, the horizontal direction, and the vertical direction are all taken when the connecting direction of the two squeeze frame members is the axial direction. Since the elastic body bends and absorbs the force acting in the direction, it is possible to prevent the skein frame from being damaged and to maintain the shape of the skein frame.

  In this case, the connecting member is a chain in which the ring bodies are movably linked to each other, a coiled spring, or a mixture of the chain and the spring, and one end of the connecting member is connected to the first mounting member. And the other ends of the connecting members can be formed as the second mounting members. Moreover, in this case, the elastic body can be attached coaxially with the squeeze frame member by a cylindrical body or a cylindrical body. Further, the elastic body can be formed by arranging a plurality of elastic blocks in which one connecting member is built along the circumferential direction of the flange.

  The elastic joint obtained in this way is fixed by the fixing member in a state where the first surface and the second surface as the mounting surfaces are in close contact with the flange of the frame member, and the frame member and the elastic joint are integrated. Therefore, the elastic body is deformed even when the sword receives an external force, and its integrity is not lost. In addition, by increasing the axial sectional area and the moment of inertia of the elastic body, using rubber with high strength and high Young's modulus as the elastic body, ensuring the bending strength and bending rigidity of the elastic joint, and elastic The length in the axial direction of the body is also shortened to keep the amount of deformation small, and even when subjected to large wave power, tidal power, or mooring force, it can maintain its shape retention function.

  According to the present invention, it is an aquaculture cake in which a rigid frame member is connected by an elastic joint, and the shape of the frame can be maintained while being flexible, and the frame member can be easily connected by an elastic joint, And it can be used in the open ocean for a long time.

It is preferable. In the example shown in FIGS. 3 to 5, the elastic body 50 is formed in a cylindrical shape, and the inner diameter of the cylindrical elastic body 50 is slightly larger than the inner diameter of the bowl member 4, and the outer diameter of the elastic body 50 is the flange 41. It is formed with a dimension slightly smaller than the outer diameter. The length of the elastic body 50 in the axial direction is not preferable in terms of function if it is too long or too short, and is 30 cm in the embodiment. In this case, one end surface of the elastic body 50 is formed as the first surface 50a, and the other end surface is formed as the second surface 50b.

Although it does not specifically limit, forming in a column shape is preferable. In the present embodiment, the cylindrical elastic block 52 has a diameter and an axial length of 19 cm and a length of 30 cm. The number of the elastic blocks 52 is a number that the elastic blocks 52 can be arranged in contact with or close to each other along the circumferential direction of the flange 41, and differs depending on the diameter of the frame member 4 and the diameter of the flange 41. Eight. One end surface of each elastic block 52 is formed as a first surface 52a, and the other end surface is formed as a second surface 52b. The elastic blocks 52 may be formed in a circular arc shape, and these elastic blocks 52 may be formed in a cylindrical elastic body by contacting or approaching each other along the circumferential direction of the flange 41.

The first attachment member 53 is embedded integrally so that the elastic body 50 and the elastic block 52 extend when one side applies a force to the elastic body 50 and the elastic block 52 in the pulling direction, and the other is the first surface 50a. , 52a projecting in a direction orthogonal to 52a and formed in a length penetrating the mounting hole of one flange 41. One of the second attachment members 54 is embedded so that the elastic body 50 and the elastic block 52 extend when a force is applied to the elastic body 50 and the elastic block 52 in the pulling direction, and the other is the second surface 50b. , 52b and projecting in a direction perpendicular to 52b and penetrating through the mounting hole of the other flange 41. A plurality of the first attachment members 53 and the second attachment members 54 are arranged in the entire circumferential direction of the flange 41. That is, the first attachment member 53 and the second attachment member 54 are provided on the plurality of elastic bodies 50 and the elastic block 52 so as to correspond to each other at a narrow interval in the circumferential direction of the flange 41. Moreover, the 1st attachment member 53 and the 2nd attachment member 54 are connected by the connection member so that it can move separately within the elastic body 50 or the elastic block 52, respectively.

  As the connecting member, for example, a spring 55 or a chain 56 in which ring bodies are linked so as to be movable is used. That is, for example, eight connecting members are provided in the elastic bodies 50 and 51, and all of these eight connecting members may be either a spring 55 or a chain 56 as shown (FIGS. 4, 5, and 7). In addition, the spring 55 and the chain 56 may be mixed.

  4 and 7, the spring 55 has, for example, an elastic portion formed in a coil shape, and the elastic portion is an elastic body in a state where the axis of the coil is parallel to the axial direction of the elastic bodies 50 and 51. 50 and 51 are embedded in an extendable manner. Both ends of the spring 55 are formed in a straight line extending from the first surfaces 50a, 52a and the second surfaces 51b, 52b at right angles to the respective surfaces, and are formed as a first mounting member 53 and a second mounting member 54, respectively. Yes. When the elastic body 50 is formed of a single cylindrical member, the spring 55 is connected to the spring 55 at an interval of 45 ° in the circumferential direction of the elastic body 50 as shown in FIG. One is provided. When the elastic body 50 includes a plurality of, for example, eight elastic blocks 52, one spring 55 is provided for each elastic block 52 as shown in FIG.

  The center part of the chain 56 is embedded in a state of being separated from each other in a straight line so that the ring bodies do not contact each other. As shown in FIGS. 5 and 8, in the chain 56, one ring body 56a is embedded in the elastic bodies 50 and 51, and parts located on both sides of the ring body 56a are partially cut off. U-shaped end bodies 56b and 56c, and two straight portions of these end bodies 56b and 56c protrude from the first surface 50a and 52a and the second surface 50b and 52b, respectively, and the two end bodies 56b and 56c. Are formed as a first mounting member 53 and a second mounting member 54, respectively. For example, the chain 56 has a dimension of a between the ring body 56a and the end bodies 56b and 56c, and a dimension of b that is twice as large as a between the end body 56b and the end body 56c. In the state, it is embedded in the elastic bodies 50 and 51 (see FIG. 8). a and b are margins that allow the elastic bodies 50 and 51 to flexibly deform and absorb the force when a large force is applied to the elastic joint 5. As shown in FIG. 5, when the elastic body 50 is formed of a single cylindrical member, the chain 56 is connected to the chain 56 at an interval of 45 ° in the circumferential direction of the elastic body 50. It has been. When the elastic body 50 is composed of a plurality of, for example, eight elastic blocks 52, one chain 56 is provided for each elastic block 52 as shown in FIG.

  The number of first mounting members 53 and second mounting members 54 that protrude from the first surfaces 50a and 52a and the second surfaces 50b and 52b of the elastic body 50 and the elastic block 52 are different depending on the connecting members, and the connecting members are springs 55. In this case, there are 8 each, and when the connecting member is the chain 56, there are 16 each. For this reason, since the mounting holes of the flange 41 correspond to the first mounting member 53 and the second mounting member 54, when the connecting member is a spring 55, eight mounting holes are provided at 45 ° intervals in the circumferential direction of the flange 41. When the connecting member is the chain 56, 16 pieces are provided.

  Thread grooves are provided on the outer surfaces of the first mounting member 53 and the second mounting member 54 protruding from the first surfaces 50a and 52a and the second surfaces 50b and 52b, respectively, and formed as screw portions 53a and 54a. A nut 58 as a fixing member is attached to the screw parts 53a and 54a. One or two nuts 58 are provided on the screw portions 53a and 54a of the first mounting member 53 and the second mounting member 54 projecting from the mutually opposing flanges 41 of the two adjacent squeeze frame members 4 via washers 59, respectively. In the illustrated example, two screws are engaged. Accordingly, the first surfaces 50a and 52a and the second surfaces 50b and 52b are fixed between the flanges 41 of the two squeeze frame members 4 in close contact with the flange 41, that is, the elastic bodies 50 and 51 are sandwiched. It is like that. That is, a frame 2 is formed in which the eight squeeze frame members 4 are connected in a circular shape by the elastic joint 5.

  Now, to use this cultured squid 1 at sea, assemble it at the quay. In order to connect the frame members 4 used when this assembly is performed to each other by the elastic joints 5, first, the first mounting members 53 of the elastic joints 5 are respectively attached to the mounting holes of the flange 41 of one of the flange members 41. The first surface 50a, 52a of the elastic body 50 or the elastic block 52 is brought into surface contact with the outer surface of one flange 41 through the flange 41 through the outer surface side. In this state, two nuts 58 are screwed into the threaded portion 53a of the first mounting member 53 protruding from the inner surface of the flange 41 via the washer 59, and the elastic body 50 and the elastic block 52 are tightened by tightening the nut 58. The first surfaces 50a and 52a are attached in close contact with the outer surface of the flange 41 of the frame member 4 on one side. Next, the second mounting members 54 of the elastic body 50 and the elastic block 52 are passed from the outer surface side of the flange 41 through the mounting holes of the flange 41 of the other cage member, respectively, so that the flange 41 is penetrated and the elastic body 50 or The second surfaces 50 b and 52 b of the elastic block 52 are brought into surface contact with the outer surface of the other flange 41. In this state, two nuts 58 are screwed into the threaded portion 53a of the second mounting member 54 protruding from the inner surface of the flange 41 via the washer 59, and the elastic body 50 and the elastic block 52 are tightened by tightening the nut 58. The second surfaces 50b and 52b are attached in close contact with the outer surface of the flange 41 of the other frame member 4. Finally, the connection of the frame member 4 and the elastic joint 5 that can tighten the nuts 58 of the screw portions 53a and 54a to a predetermined torque with a torque wrench is completed.

  As a result, the two sacrificial members 4 are connected by the elastic joint 5. In addition, when the elastic body 51 is formed of the eight elastic blocks 52, this operation is performed for each of the eight elastic blocks 52. As described above, the first mounting members 53 protruding from the first surfaces 50a and 52a of the elastic block 52 forming the elastic body 50 and the elastic body 51 are protruded from the flange 41 of the one frame member 4 so that each of the first mounting members 53 protrudes. A nut 58 is attached to each mounting member 53, and each second mounting member 54 protruding from the second surfaces 50b and 52b of the elastic body 50 and the elastic block 52 is protruded from the flange 41 of the other skeletal frame member 4. By attaching the nuts 58 to the second mounting members 54, the elastic bodies 50 and 51 are brought into close contact with the flanges 41 by the flange 41 of the one skeletal frame member 4 and the flange 41 of the other skeletal frame member 4. The two squeeze frame members 4 are connected to each other by the elastic joint 5. Therefore, the frame member 4 can be easily connected by the elastic joint 5. As a result, it is possible to easily assemble the skein frame 2 in which the eight skein members 4 are connected in a circular shape by the elastic joint 5.

  The skein frame 2 is lifted by a crane using the attachment piece 43 of the flange 41 of the skein frame member 4 and moved from the land to the sea. And, it is possible to cultivate seafood in the open ocean area by towing the frame 2 after being towed to a predetermined location in the open ocean area at sea.

  This cultured ikesu 1 receives large wave power, tidal current power, and mooring power in the open ocean. For example, when the squeeze frame member 4 has a large rigidity when subjected to a large force due to waves, the large force acts on the elastic joint 5 that connects the skein frame members 4 to each other. The elastic bodies 50 and 51 constituting the elastic joint 5 are in close contact with the entire circumferential direction of the flange 41 of the frame member 4, and the first mounting member 53 and the second mounting member 54 are arranged around the flange 41. Since the frame member 4 and the elastic joint 5 are integrated with each other in the direction, the elastic bodies 50 and 51 are deformed even when the cake 1 receives an external force, and the unity is lost. Absent.

  That is, when the connecting direction of the frame member 4 is the axial direction (the axial direction of the elastic body), the elastic bodies 50 and 51 bend and absorb forces acting in all directions including the axial direction, the horizontal direction, and the vertical direction. For example, when a force (compression force) is applied in the axial direction in which the interval between the flanges 41 of the frame member 4 is reduced, the elastic bodies 50 and 51 are contracted by the two flanges 41 and the elastic bodies 50 and 51 absorb the force. To do. Further, when a force (tensile force) is applied in the axial direction in which the interval between the flanges 41 is widened, the first mounting member 53 and the second mounting member 54 pull the elastic bodies 50 and 51, respectively, and the elastic bodies 50 and 51 extend. Absorb that power.

  The force acting in the horizontal direction and the vertical direction is a force acting so that the two squeeze frame members 4 bend around the elastic bodies 50 and 51, and when this force acts on the elastic bodies 50 and 51, the inner elasticity that bends. As for the bodies 50 and 51, the space | interval between the flanges 41 becomes narrow, the elastic bodies 50 and 51 shrink | contract, and the outer elastic bodies 50 and 51 which bend | fold are widened, and the space | interval between the flanges 41 becomes wide and the 1st attachment member 53 and 2nd. The attachment members 54 pull the elastic bodies 50 and 51, respectively, and the elastic bodies 50 and 51 extend to absorb the force. Further, the elastic bodies 50 and 51 are in close contact with the flange 41 of the frame member 4 on the entire surface in the circumferential direction of the flange 41, and the first mounting member 53 and the second mounting member 54 are respectively connected to the periphery of the flange 41. Since the two squeeze frame members 4 are bent about the elastic bodies 50 and 51, the elastic bodies 50 and 51 are deformed in the same manner and absorb the force regardless of the bending direction. To do.

  For example, when a circular cultured sushi 1 having a diameter of 30 m receives a wave having a wavelength of 100 m and a wave height of 5 m, the cultivated sushi 1 is not deformed as shown in FIG. Due to the deformation of 5, the impact force generated in the cultured sushi 1 is relieved so as to follow the shape of a substantially wave. In addition, FIG. 9 is a figure which shows the state in which the culture craft 1 got on the top of a wave.

  Therefore, since the cultured frame 1 of the present embodiment is connected to the frame member 4 made of a relatively cheap steel material as the main material by the elastic joint 5, when receiving a large wave force, tidal force, or mooring force, The elastic bodies 50 and 51 constituting the elastic joint 5 expand and contract and deform, and the skein frame 2 flexes flexibly to absorb the force and not receive a large impact force, so that the skein 1 is prevented from being damaged. As a result, an aquaculture cup 1 corresponding to an economical open sea can be obtained.

  If it is too flexible, it will receive tidal power, wave force, and horizontal force of mooring force, but it will lose its flat shape, and it will not be possible to lift with a crane at the time of launch, making the construction complicated, This is caused by the drawbacks of taking a lot of time and so on but being too soft. Therefore, in this embodiment, the elastic body 50, 51 of the skein 1 is increased in the axial sectional area and the moment of inertia of the cross section, and the elastic body 50, 51 is made of a high strength rubber having a large Young's modulus. When the bending strength and bending rigidity of the joint 5 are ensured and the length of the elastic bodies 50 and 51 in the axial direction is shortened to keep the deformation amount small, and when receiving a large wave force, tidal force or mooring force, I can keep the shape function even when I lift it.

  As described above, the cultured sushi 1 of the present embodiment can be deformed to a necessary extent so as to reduce the impact force, but loses its shape maintaining function and does not cause excessive deformation that leads to the destruction of the elastic bodies 50 and 51. It becomes possible to do.

  In addition, the first mounting member 53, the second mounting member 54, and the connecting member for fixing the elastic bodies 50, 51 are embedded in the elastic bodies 50, 51 so that they can be used for a long time in the open ocean. Also, the connection of the frame member 4 by the elastic joint 5 can be held.

In the present embodiment, the skein frame 2 is formed in a circular shape, but the skein frame may be formed in a polygonal shape. In this case, an elastic joint may be provided at a corner of the skein frame, or a straight portion. An elastic joint may be provided, or an elastic joint may be provided at both the corner and the straight part.
Moreover, although the case where the aquaculture ike of this embodiment was used in an open-sea area was not limited to this, you may make it use on the waters, such as the sea other than an open-sea area, a lake, and a dam. Furthermore, although the elastic joint of this embodiment demonstrated the case where the frame member which aquaculture Ike is connected, it is not limited to this, For example, the frame member used in underwater engineering works, such as a submarine dredging construction and a landfill construction You may use when connecting.
