Description

  The present invention is a nori culture using a prop system in which a nori net is stretched on a pillar standing in the sea and the nori is cultivated in this nori net. The present invention relates to a device for fixing a length adjusting rope for maintaining a net at a certain depth from the sea surface to a column, a common name, and a ridge.

  As shown in FIG. 7, as a conventional laver-cultivating laver netting device for supporting nori culture, as shown in FIG. 7, a suspension rope b attached to a number of struts a standing at an appropriate interval on the sea floor of a shallow water. It is supported by. Furthermore, extending bars d are provided at substantially intermediate positions of the many struts a in the short direction of the laver net c, with both ends locked to the curb e, thereby buoyancy in the laver net c. In addition, twisting of the laver net c is prevented.

  In this structure, the strut a and the curb e are coupled by a suspension line b having a large slack, so that the curb line coupled to the suspension line b in accordance with the vertical movement of the sea surface due to tides. The position of e also moves up and down, and accordingly, the position of the laver net c attached to the curb e is also adjusted to some extent.

  However, the amount of movement of the laver net c is large for the horizontal movement of the laver net c due to the flow of the tide and wind, and the left and right sides of the laver net c are adjusted only by adjusting the length of the suspension rope b. It was difficult to position it appropriately for front and back horizontal movement.

  As means for solving the problem of laver net movement due to tides and flows, Patent Document 1 discloses that a curb line e supporting a laver net c as shown in FIG. Further, by connecting the suspension rope b to a floating ring f having buoyancy with respect to the seawater inserted through the support column a, the laver net c is moved up and down by the tides and the flow of the tide. In addition, a laver netting device that can cope with horizontal movement of laver nets by the wind on the sea is disclosed.

  In order to cultivate nori efficiently, the nori net c must be positioned at a depth of about 0.5 to 1 m below the sea surface. For that purpose, the suspension rope b connected to the laver net c is formed of a loose rope, and the end of a fixed length of the adjustment rope g fixed to the support post a is directly connected to the suspension rope b via a floating ring f. The length is adjusted when connecting.

  When the floating ring f is used, the movement of the floating ring f due to the tides is regulated by setting the end of the adjustment rope g to the length at the time of low tide. The floating ring f is prevented from reaching a certain depth or more from the high tide at low tide.

  Regardless of whether or not the floating ring f is used, in order to fix the depth adjusting rope g for regulating the vertical movement of the laver net c to the support pillar a, the tightness of the rope to the support pillar a is sufficient. It is necessary to prevent the support surface from slipping down. For this purpose, a snap is formed by a leash, or the method of tying the leash is devised to fix it to the prop.

However, the work to fix the length adjustment rope to the support to regulate the range of movement of the seaweed net is from the top of the boat swaying in the waves and wind, and the support surface is also wet. Therefore, it is slippery and requires labor and skill, which is a major obstacle to the efficiency of laver net installation work.
Japanese Patent No. 3424891

  The problem to be solved in the present invention is to provide an instrument for easily and surely fixing a length adjusting rope for stably maintaining a laver net at a predetermined depth to a support column.

  The present invention is a device for fixing the depth adjustment rope of the seaweed aquaculture net attached to the struts that are erected at intervals, and comprises a plurality of members obtained by dividing the ring into semicircular shapes. One end portions of the divided members are connected to each other so as to be rotatable, and the other end portions are formed to be connected and fixed.

  Since the fixing device of the present invention is usually attached and fixed to a support column having an outer diameter of about 50 mm, a closed ring-shaped inner diameter is slightly smaller than that of the support column so that it does not fall after mounting and fixing. It is necessary to have a small diameter, and it is also necessary to provide an uneven surface or other anti-slip on the inner hole surface of the formed ring.

  In addition, the work environment for installation is to be attached to the surface of the support column wet with sea water by hand on a small boat, and it is easy to hold and has good workability. Therefore, in the sea, it is convenient not only to have a ring-shaped outer shape with low resistance, for example, a frame-shaped outer shape, but also to have a donut shape. Further, in order to prevent slipping during handling, the outer shape can be formed into a polygonal shape with rounded corners, or a star shape.

  Furthermore, the means for connecting and fixing the end portions of the divided members can be constituted by locking members formed at the respective end portions. As the locking member, a locking portion can be formed at the end of the divided member, a locking member can be attached, and the fastening member is inserted from the outside. An arbitrary form such as a form to be taken can be taken.

  This fixing device can be fixed to the column easily and securely, and the adjustment rope can be easily attached using the insertion hole formed in this fixing device. Regardless, the laver net can be accurately and easily placed at a predetermined depth and position.

  Hereinafter, embodiments of the present invention will be described by way of examples.

Example 1
1 and 2 show the outer shape of the fixing device 10 according to the first embodiment of the present invention. FIG. 1 shows a state before being attached to the column, and FIG.

  In the figure, a fixing device 10 according to the present invention comprises a piece-like main body 1 made of a hard and corrosion-resistant plastic material, having a thick central portion and a thin end portion, and an inner hole for passing through a pillar in the center. 2 is formed in a ring shape.

  The ring-shaped main body 1 is formed of two half-string-shaped divided members 11 and 12, and one end portion, that is, the base portion thereof is pivotally supported by a pin 3 so as to be freely opened and closed.

  A notch 4 is formed at the other end of each of the divided members 11 and 12, that is, an open end, and the open end of each of the divided members is connected to the notch 4 to form a ring shape as a whole. A locking device 5 for forming is provided.

  As shown in FIG. 2, the notch 4 is formed by connecting the open ends of the divided members 11 and 12 to form a ring shape as a whole, and when the column a is fixed to the inner hole 2, This is to prevent the locking device 5 from being unlocked when it protrudes outward from the outer peripheral surface of the ring-shaped fixing device 10 and obstructs the laver net work.

  In addition to the clasp type, the locking device 5 may be a spring material that locks both ends thereof. In this case, instead of forming the notch 4 at the open end of the dividing member, a groove can be formed in the outer peripheral surface thereof. In addition, as the locking device 5, a locking mechanism may be formed integrally with each divided member, or a locking mechanism with a spring may be used.

  6 is a slip stopper provided along the inner periphery of the inner hole 2 to prevent the instrument 10 from slipping down when the instrument 10 is fastened to the outer peripheral surface of the support column.

  7 shows a hole for inserting an adjustment rope for holding a laver net provided penetrating from the instrument surface to the back surface at a specific position below the sea surface.

  The fixing device 10 of the present invention is attached to the support column with the divided members 11 and 12 opened, and then the locking device 5 attached to the open ends of the divided members 11 and 12, respectively, as shown in FIG. By simply fastening, it can be firmly tightened and fixed to the column a.

  Since the fixing device 10 is firmly fixed to the support post a in this way, the adjustment rope for adjusting the stop position of the seaweed net below the sea level can be functioned only by being attached to the fixing device 10. As described above, since the adjustment rope itself is not fastened to the support column, the installation work is simplified.

  FIG. 3 illustrates a usage form of the fixing device 10 of the present invention, taking as an example the case where the floating ring f is used. Of course, the floating ring f can be used directly for supporting the laver net c by the suspension rope b without using the floating ring f.

  In the figure, I indicates the water level at low tide, and II indicates the water level at high tide. The fixing device 10 of the present invention is attached and fixed to the support column a at a position about 1 m lower than the water level II at the time of high tide in the above-described manner, with the timing of the water level between low tide and high tide.

  In the case of the figure, the depth adjustment rope g has a predetermined position in order to position the laver net c attached via the floating ring f at 0.5 m below the sea level regardless of low tide or high tide. And is attached to a floating ring f disposed at a position below the fixing device 10 via the fixing device 10. ing.

  The length of the depth adjustment rope g is preferably a length corresponding to the difference in tidal range. A suspension rope b that supports the laver net c is attached to the floating ring f. Then, the floating ring f moves up and down due to the difference in tidal range, and accordingly, the suspension rope b attached to the floating ring f also moves up and down.

  At that time, since the depth adjustment rope g is fixed by the fixing device 10, if the length of the depth adjustment rope g is adjusted to a predetermined length in advance, the degree of ebb tide temporarily exceeds the average. Even in this case, since the floating ring f is restrained by the length of the depth adjusting rope g, the movement of the suspension rope b that supports the laver net c attached to the floating ring f is also restricted. This makes it possible to always keep the laver net c at a predetermined position below the sea surface.
