Description

  The present invention relates to a cylindrical shell for shellfish in which a support frame of a cylindrical continuous shell for rods used for culturing shellfish and the like is reinforced.

  Conventionally, a multi-stage rod used for aquaculture of shells such as scallops, oysters, and pearl shells has a circular support frame arranged in multiple stages, and two reinforcing beams connected to the inside of the support frame for reinforcement. Are arranged in a cross, a side net connected to the outer periphery of the support frame, a dish net connected on a dish part formed by the support frame and the reinforcing beam, and attachment of the reinforcing beam of the support frame Cylindrical scissors are known which are provided with four hanging ropes connected to the part and an opening for taking shells in and out of the trunk of the side net.

However, in the conventional configuration as described above, when the anchor is rolled up on the ship, the support frame is strongly pressed against the shipboard by the load of the anchor, and thus deforms.
If you try to pull it back later by hand, the support frame will be plastically deformed, and the side frame and the dish net are connected to the support frame. It will not be a situation.
The reeds that can no longer be restored can no longer be used, which in turn causes pressure on the fishermen's management.

On the other hand, there is known a continuous culture cage that can reduce the dead space of the shelf of each stage of the cylindrical culture cage as much as possible to improve tide and increase the net area of the living area to be cultured. (See Patent Document 1).
This known technique includes a circular support frame arranged in a plurality of steps, an outer enclosure made of a mesh provided outside the circular support frame of each step, and a Y-shaped reinforcement attached to the circular support frame. A pedestal, a shelf that is attached to the circular support frame of each step and forms a plurality of storage chambers in the outer enclosure, and an input / discharge of an aquaculture object formed on the trunk of the outer enclosure And a three-stage cultivating cage provided with three suspension ropes connected to a reinforcing bar mounting portion on the outer periphery of the circular support frame.
In FIG. 2C of this Y-shaped reinforcing bar, the distance between the connecting portions of the reinforcing beams on the support frame is longer than that in FIG. 2B of the conventional two beams, so that the strength of the support frame is increased. When the kite is rolled up on the ship, the support frame is more easily deformed than the conventional kite.
This multistage cage has been troublesome in welding the Y-shaped reinforcing bar, and the welded portion may become defective in butt welding, so that it was not actually commercialized.

  An object of the present invention is to provide a cylindrical shell for shellfish having an enhanced support frame that prevents deformation of the support frame when a cylindrical continuous rod is rolled up.

A cylindrical shell for shellfish with an enhanced support frame according to the present invention is formed by covering a circular support frame, three reinforcing beams connected to the support frame, and the support frame and the reinforcing beams with a net. A connecting portion between the support frame and the reinforcing beam, the dish net, a side net formed by placing the dish net at a predetermined interval and covering the outside of the dish net with a net. A hanging rope that is connected in multiple stages by forming knots in the same manner, passing through the meshes of the side nets, and similarly forming knots at the joints between the support frame of the lower tray net and the reinforcing beams. The reinforcing beams of the book are coupled so that the angle of intersection between the reinforcing beams and the reinforcing beams is 60 °.
The suspension rope is connected by three suspension ropes so as to be equally divided at the joint between the support frame and the reinforcing beam.
The three hanging ropes are colored differently from the other two.

  The shell-shaped cylindrical cultivating rods with enhanced support frames of the present invention can greatly reduce the deformation of the support frames due to external forces when winding the rods on the ship by using three reinforcing beams. Repairs are greatly reduced and working hours can be shortened, and the rods are not damaged, so the service life can be increased and fishermen's management can be improved. Further, by using three reinforcing beams, six connecting portions of the reinforcing beam ends on the support frame are formed, so that three suspension ropes can be easily formed, and the plane is formed by three points. Therefore, it is more stable than the four hanging ropes. In addition, with the four hanging ropes, if the length of the rope is a little different, the dish net will tilt, and the shellfish will come to one side. Since the outer circumference of the shell is damaged and the damaged portion cannot be grown thereafter, it becomes a shellfish that is not sold as a shellfish.

  The cylindrical shell for shellfish with enhanced support frame according to the present invention has three suspension ropes, so that a plane determined by three points is established, and the dish net portion can be maintained on a horizontal plane. Therefore, it is possible to prevent the shellfish being cultivated from moving to one side, promote the growth of the shellfish, reduce the accident of the shellfish colliding with each other, and improve the catch. In addition, the three suspension ropes have less tidal resistance than the four suspension ropes, so there is less swaying and tilting of the baskets due to tidal currents, and the corresponding anchors are stable, shell growth is large, and the catch It can lead to improvement.

  Since the shellfish cylindrical culture rod with the support frame of the present invention is colored differently from one of the three hanging ropes, the colored rope should be placed on the opposite side of the opening. Thus, by lifting the colored rope, the opening becomes downward and the shell can be quickly put in and out.

It is a schematic perspective view which shows the cylindrical cultivation cage | shell of the shellfish which strengthened the support frame of this invention. FIG. 6 is a schematic plan view showing a plan view of a support frame (a) three reinforcing beams of the present invention, (b) two conventional beams, and (c) a beam of Patent Document 1.

One embodiment of a shell-shaped cylindrical shell of a shell having an enhanced support frame according to the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the cylindrical shell for shellfish having an enhanced support frame according to the present invention includes a circular support frame 1 and three reinforcing beams 2 that are overlapped and joined so as to pass through the center of the support frame 1. And a dish net 3 formed by covering the support frame 1 and the reinforcing beam 2 with a net, and the dish net 3 are arranged vertically at a predetermined interval, and the outside of the dish net 3 is covered with a net. Similarly, a knot is formed on the side net 4 formed in the shape of a shape and a joint 5 between the support frame 1 and the reinforcing beam 2 and passes through the net of the side net 4 to form the lower tray net 3 in the same manner. The suspension rope 6 is formed by connecting a knot.

  The three reinforcing beams 2 are thin reinforcing rods, and the overlapping portion 8 is joined by welding, bonding, clips, metal fittings, tie straps or the like so as to pass through the center of the support frame 1. 2 is coupled to the coupling portion 5 of the support frame 1 so that the crossing angle with 2 is 60 °.

A plurality of the suspension ropes 6 are continuously connected to the upper and lower multistage plate nets 3 by the three suspension ropes 6 so as to be equally divided into the connecting portions 5 between the support frame 1 and the reinforcing beams 2.
The three hanging ropes 6 are colored differently from the other two on one side opposite to the opening.
In addition, the number 7 is an opening part which inserts and discharges shellfish.

Next, the operation and effect of the cylindrical shell for shellfish with a strengthened support frame according to the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the shell-shaped cylindrical culture rod of the present invention having a strengthened support frame is welded, bonded, clipped, and metallized with an overlap portion 8 so that it passes through the center of the support frame 1 by three reinforcing beams 2. In addition, the reinforcing beams 2 having a small diameter are used because they are joined to the connecting portion 5 of the support frame 1 so that the crossing angle between the reinforcing beams 2 and the reinforcing beams 2 is 60 °. Even so, the distance between the connecting portions of the reinforcing beams on the support frame (see FIG. 2A) is shorter than that of the conventional double beam (see FIG. 2B). Since the number of reinforcing beams changes from two in FIG. 2 (b) to three in FIG. 2 (a), the structure can withstand deformation caused by external forces from all directions, so deformation due to external forces is greatly reduced. For this reason, even if the round rod is strongly pressed against the shipboard during winding, the deformation of the support frame is greatly reduced. Further, due to an increase in the load due to the growth of the shell, there is no risk of deformation even if a load is applied to a place where the reinforcing beam is not connected.

In addition, the shell-shaped cylindrical cultivating rod with the enhanced support frame according to the present invention has a plate net 3 in the upper and lower stages by three suspension ropes 6 so as to be equally divided into the joint 5 between the support frame 1 and the reinforcing beam 2. Since many planes are connected continuously, the plane is determined by three points, so the sharks are more stable than the four suspension ropes, and the tidal waves and inclinations caused by tidal currents and shellfish grow during the cultivation in the sea. Even when the load increases or when the center of gravity of the round gourd moves due to the movement of the shellfish, the dish net is not displaced or loosened, and the suspension in a stable state can be maintained.
Moreover, the resistance of the tidal current can be reduced by changing the number of the suspension ropes from four to three, and the posture of the salmon during aquaculture can be further stabilized. In particular, when aquaculture is continued for a long period of time, seaweeds and shellfish adhere to the rope, and thus the resistance to tidal current is further increased. For this reason, reducing the number of ropes from four to three can greatly reduce tidal resistance, stabilize the heel posture, promote shell growth, and in turn improve fishing. It becomes like this.

  In addition, the shell-shaped cylindrical cultivating rod with the enhanced support frame of the present invention is colored differently from the other two by the three hanging ropes 6, so the colored rope is opposite to the opening 7. By disposing, the opening 7 becomes downward by lifting the colored rope, and the shell can be discharged quickly.
