Description

  The present invention relates to equipment technology for cultivating kelp.

  Cultured kelp is popular on the market because it is softer than natural kelp and can produce high quality soup that is comparable to natural kelp.

  FIG. 6 shows an example of a culture facility for producing cultured kelp. This aquaculture equipment 1 includes a cross member 3 disposed in the sea 2, a vertical member 4 that supports an end portion of the cross member 3, and a plurality of growth materials 6 for growing the culture kelp K. These upper ends are fixed to the cross member 3. Symbol S is the sea level.

  In a normal case, the cross member 3, the vertical member 4, and the growing member 6 use ropes.

  Conventionally, the following Patent Document 1 has been proposed as a technique for such aquaculture equipment.

  Since it is a facility for cultivating kelp, the cross member 3 is positioned in the sea 2 below the sea level S. Since the cross member 3 has a long length, for example, a length of 100 to 200 m, it is preferable to place a floating ball (not shown) at an appropriate place to maintain the horizontal posture of the cross member 3.

  As shown in FIG. 7, the rope of the vertical member 4 that supports both ends of the cross member 3 is fixed to a heavy anchor block 5 at its lower end, for example. More preferably, the vertical member 4 is supported by two ropes having an inverted V shape. This is to stabilize the cross member 3 by suppressing the movement of the vertical member 4 due to the ocean current. A member that binds / engages the rope to be the vertical member 4, such as an engagement hook (not shown), is disposed at an appropriate position (for example, the upper surface) of the anchor block 5, and the engagement hook or the like is interposed therebetween. The rope which becomes the vertical member 4 is engaged.

  Normally, the growing material 6 arranges kelp seedlings at an appropriate interval in the vertical direction. Alternatively, a means (for example, a fiber material having a void, a net material, etc.) having a kelp seedling (a zoospore; male gametophyte / female gametophyte) in the sea is provided.

  Further, the upper end portion of the growing material 6 is previously tied (bundled) and fixed to the rope that is the cross member 3.

  Cultured kelp K will be harvested in about two years. At the time of harvesting, the boat is taken out from early morning, the cross member 3 bound to the vertical member 4 is removed, and the cross member 3 is collected.

  Thereby, the growing material 6 connected to the cross member 3 and the cultured kelp K attached to the growing material 6 are collected.

JP2005-110612

  The problem is that when the sea is damaged by a typhoon or a tsunami, if the appropriate measures to protect the cultured kelp K are not taken, the growth of the cultured kelp K will be greatly damaged. This is as follows.

  First, when seawater flow becomes intense due to typhoon or tsunami, and a strong water pressure is applied to the whole cultured kelp K, as a result of the tensile force acting on the horizontal member 3 and the vertical member 4, the anchor block that supports the lower end of the vertical member 4 5 may fall (roll over).

  For this reason, when the sea is rough (when it is timed), it is desirable to protect the cultured kelp K by lowering the crosspiece 3 deeply in the sea as soon as possible.

  However, there are cases in which it is not always possible to take appropriate measures, such as sudden changes in weather or the occurrence of unexpected tsunamis. Since the anchor block 5 has a very large weight and does not fall down due to slight aging or tsunami, it is not easy to determine whether or not to lower the cross member 3 deeply in the sea. And if appropriate judgment is delayed, it will be seriously damaged.

  Moreover, even if the anchor block 5 does not fall down (rollover) as a result, the quality of the cultured kelp K deteriorates as a result of the collision of violently flowing seawater for a long time, and the commercial value (market price) is reduced. There is.

  Therefore, the object of the present invention is to prevent the anchor block from falling or the quality of the cultured kelp caused by aging or tsunami without taking appropriate artificial measures such as lowering the cross members placed on the sea surface / near the sea surface. The purpose is to prevent deterioration.

  In order to achieve the above object, a kelp aquaculture facility according to the present invention comprises a cross member that floats on the sea surface, a vertical member that supports one end of the cross member, and a plurality of growth materials for growing kelp. And a kelp aquaculture facility for fixing each upper end of the growing material to the cross member, wherein the vertical member is disposed only at one end of one side of the cross member, and the lower end is fixed to the anchor block. A rope member or a bundle of ropes, and the cross member is a single rope member or rope bundle, and includes a buoyant body covering the cross member in the longitudinal direction, and one end portion of the cross member is the longitudinal member. It is moored to the material, and the other end is not moored and can float.

  In this aquaculture equipment, a horizontal member is floated on the sea surface, one end is fixed (tethered) to the vertical member, and the other end is not moored. For this reason, even if the sea is timed by a typhoon or the like, or when a tsunami occurs due to an earthquake, the position of the cross member is freely changed according to the flow of seawater.

  For this reason, the collision pressure of seawater on the cultured kelp can be released, the tensile force on the cross member and the vertical member can be reduced, and the anchor block can be prevented from overturning.

  Moreover, since the collision pressure of seawater on the cultured kelp can be reduced, the quality of the cultured kelp is hardly deteriorated.

  In some cases, an end float that floats and moves the cross member around the vertical member according to the wind direction may be provided near the end / end of the cross member that is not moored (Claim 2).

  By providing the end float, the cross member moves to a position where it is difficult to receive wind according to the wind direction.

  The direction of the wind and the direction of the water on the sea surface are not completely the same. However, in the case of strong winds, there is a correlation between the direction of the wind and the direction of the water on the sea surface. Therefore, in the case of bad weather (aging), damage to cultured kelp caused by seawater flow near the sea surface / sea surface can be mitigated.

  Either a buckle or an engagement tongue is arranged on the cross member, and either one of the engagement tongue or the buckle is arranged on the upper end portion of the growing material, and the buckle and the engagement tongue are engaged. In some cases, the growing material is fixed to the cross member at an appropriate interval (claim 3).

  Conventionally, the upper end portion of the growing material (rope) is a method of binding (connecting) to the cross member (rope). On the other hand, if the upper end portion of the growing material is engaged with the cross member using the buckle and the engaging tongue, not only the growing material but also the removal material can be easily removed.

  When collecting cultured kelp, it is desirable to dry the collected kelp in the sun in a short time. However, in the conventional method, the separation of the horizontal material and the growing material is cumbersome, so the whole is recovered and separated in the dry field. Worked to dry in the sun.

  By using the engagement method with the buckle and the engagement tongue, it is possible to perform the removal work at sea, so it is possible to remove the necessary number of growing materials and carry them to the hay, and quickly dry the cultured kelp to the sun. The work load is reduced because it is not necessary to carry in the whole but only the necessary amount.

  In addition, the shorter the time from collection to kombu drying, the better the quality of the dried kelp. By using the buckle and the engaging tongue, the necessary number of growing materials are transported to the dry field, so that the sun drying process can be performed quickly.

  Since the amount to be dried can be adjusted, there is an advantage that the operation can be performed even if the number of workers is small.

  According to the kelp culture facility according to the present invention, it is possible to prevent the anchor block from falling and the quality of the cultured kelp from deteriorating due to aging or tsunami without taking artificial measures.

It is a figure which illustrates other example of arrangement of the growth material concerning the present invention. It is a figure which illustrates the other example of arrangement | positioning of the crosspiece which concerns on this invention. It is a figure which illustrates the case where a buckle is used for the growth material concerning the present invention. It is a figure which shows the conventional aquaculture equipment. It is a figure which illustrates the specific structure of the vertical member shown in FIG.

  1 and 2 show a first embodiment of a kelp culture facility according to the present invention.

  The aquaculture equipment 10 includes a cross member 11 that floats on the sea surface S, a vertical member 20 that supports one end of the cross member 11, and a plurality of growth materials 30 for growing kelp K. Are fixed to the cross member 11.

  The longitudinal member 20 is disposed only at one end portion of the transverse member 11. The lower end 20-1 is fixed to an anchor block 19 arranged on the seabed. The vertical member 20 is specifically a flexible rope, and is composed of, for example, a single rope member or rope bundle.

  The cross member 11 is specifically composed of a flexible rope, for example, a single rope member or a rope bundle, and includes a buoyant body (float) 40 covering the cross member 11 in the longitudinal direction. The cross member 11 has one end portion 11-1 moored near the upper end of the longitudinal member 20, and the other end portion 11-2 is non-tethered and can float.

  Hereinafter, each part will be described.

  The cross member 11 is provided with a buoyancy body 40 in the longitudinal direction in order to float on the sea surface S.

  As the buoyancy body 40, an inner hollow cylindrical body (bottomless and uncovered) formed of resin / glass / metal or the like can be used. Any material may be used as long as the cross member 11 is inserted into the central hole of the cylindrical body and sufficient buoyancy is given to the cross member 11 by the air (other gas) inside the cylindrical body. The shape of the cylinder can be designed as appropriate. Either a cylindrical shape or a polygonal cylinder may be used.

  The cross member 11 supports the growth material 30 arranged at an appropriate interval, and the growth material 30 grows the kelp K. Therefore, the weight increases as the kelp K grows, and A strong pulling force works. The buoyancy body 40 has buoyancy that maintains the state in which the cross member 11 is floated on the sea surface S (or in the vicinity of the sea surface) even when the kelp K grows.

  It is desirable that the buoyancy body 40 is divided into a plurality of parts and arranged in the longitudinal direction of the cross member 11. This is because the cross member 11 can be prevented from being damaged by flexibly changing the shape even when the sea surface S is complicated, for example, up and down. This is because, if the entire structure is continuously wrapped from the end to the end of the cross member 11, the size becomes long, the possibility of breakage and damage increases, and handling becomes difficult.

  As the cross member 11 and the vertical member 20, it is desirable to use a flexible rope. This is because it can respond flexibly to the movement of seawater and is less likely to break. As the rope member used for the cross member 11 and the vertical member 20, a rope bundle obtained by bundling one rope member or a plurality of rope members is used. This is to simplify the configuration of the aquaculture facility 10 and to reduce the pressure of seawater applied to the rope material. Although a metal rope may be used, it is preferable to use a more flexible rope material such as a hemp rope.

  An appropriate material can be used as the growth material 30. For example, non-metallic rope materials, resin belt materials, and the like. In this case, the growing material 30 is suspended in a substantially vertical direction with respect to the arrangement direction of the cross member 11. It is desirable that the growing material 30 be flexible in its posture following the movement of seawater.

  The growing material 30 is fixed to the cross member 11 by an appropriate method. For example, when a single rope material is used as the growth material 30, the upper end portion thereof is tied to the cross member 11 and fixed.

  Since the buoyant body 40 is disposed on the cross member 11, the growing material 30 is engaged with, for example, a gap between adjacent buoyant bodies 40 (a portion where the cross member 11 is exposed).

  It is desirable to fix a member having a kelp seedling (a zoospore; male gametophyte / female gametophyte) in advance, such as a seedling net, at appropriate intervals. This is because aquaculture efficiency can be increased by arranging seedling nets and the like in advance.

  Since the vertical member 20 is a single rope member / rope bundle, the anchor block 19 that supports the lower end portion thereof may be one. The vertical member 20 and the anchor block 19 are fixed by an appropriate method, for example, a ring member or a hook member is fixed to the upper surface of the anchor block 19 and a hook member / ring member corresponding to the lower end portion of the vertical member 20 is engaged. It is provided and the lower end part of the vertical member 20 is fixed by engagement of both.

  It is desirable to provide the first float 18 at the upper end of the vertical member 20 for easily recognizing the position of the vertical member 20 from the sea. Since the 1st float 18 is provided for position confirmation, what is necessary is just to be easily visually recognized from the outside.

  The first float 18 serves as a mark of one end of the cross member 11, but the second float (hereinafter referred to as end float) is provided at the other end (unfixed open end) of the cross member 11. It is desirable to arrange 17.

  The end float 17 freely floats the open end of the cross member 11 in accordance with the wind direction. Therefore, it is desirable that the end float 17 is of a size that allows the open end of the cross member 11 to swim (float) freely by receiving wind. The shape does not matter. Even a conventional spherical float has a function of moving the open end of the cross member 11 in response to wind. Because the purposes are different, the size of the first float 18 and the end float 17 need not be the same.

  Therefore, according to such a configuration, the cross member 11 can freely change the position in the vertical direction and the horizontal direction during a typhoon or when the sea is rough, and the pressure of the wind or sea water can be released. For this reason, it becomes possible to reliably prevent troubles that are troublesome for the fisherman, such as the fall of the anchor block 19.

  Further, the growing material 30 fixed to the cross member 11 and the kelp K grown on the growing material 30 are not affected by the movement of wind or seawater. For this reason, the possibility of quality deterioration of kelp K can be further reduced.

  As shown in FIG. 3, the growing material 30 may be fixed to the cross member 11 through a plurality of branched materials 35.

  Since the aquaculture equipment 10 according to the present invention freely changes the position of the crosspiece 11, it may not be preferable to make the crosspiece 11 have a long structure because of the relationship with the area of the farm.

  Therefore, in order to prevent the yield of kelp K from being reduced even if the longitudinal dimension of the cross member 11 is shortened, the growing material 30 may be provided via the branch material 35.

  In FIG. 3, in order to make the drawing easier to see, the branch member 35 is not shown in the portion indicated by the symbol Z (the gap portion of the buoyancy body 40), but actually, the branch member 35 is also provided in the portion indicated by the symbol Z. Even with a short crosspiece 11, it is desirable to ensure a sufficient yield of kelp K. The branch material 35 is not limited to the bifurcated member, but may be a bifurcated member having many branches.

  Further, as shown in FIG. 4, a branch connecting member 25 may be provided in the vicinity of the upper end portion of the vertical member 20, and a plurality of cross members 11 may be arranged through the branch connecting member 25. More preferably, it is desirable to connect the branch connecting member 25 and the cross member 11 using the branch rope 26. The branch rope 26 is desirably provided with, for example, a stretching member 27 so that the cross member 11 is expanded and disposed. The extending member 27 can be appropriately configured such as a rope member, a rope bundle, a rod member, a tubular member, and the like.

  FIG. 5 illustrates a member for fixing the growing material 30 to the cross member 11.

  Usually, although the upper end part of the growth material 30 is tied to the cross member 11, removal is troublesome. Therefore, either the buckle 51 or the engagement tongue 52 is disposed on the cross member 11, and either the engagement tongue 52 or the buckle 51 is disposed on the upper end portion of the growing material 30 to engage the both. It is desirable to enable easy attachment / detachment.

  The buckle 51 / engagement tongue 52 can be a vehicle safety belt, for example. For example, automobiles, passenger planes, seat belts used in amusement parks, and the like.

  Safety belts used in automobiles are most preferable for use in the sea because they can be easily engaged / disengaged and have excellent rust prevention treatment for members.

  The positional relationship between the buckle 51 and the engagement tongue 52 may be opposite to that shown in FIG. This is because even if the engagement tongue 52 is fixed to the cross member 11 and the buckle 51 is fixed to the upper end portion of the growing material 30, the workability of engagement / disengagement is substantially the same.

  When an automobile seat belt is used, belt materials 54 and 58 are fixed to the buckle 51 and the engagement tongue 52. Therefore, the belt materials 54 and 58 may be used as the growth material 30 as they are.

  In this embodiment, since the buckle 51 is fixed to the cross member 11, the buckle 51 can be fixed via the belt member 54 fixed to the buckle 51. For example, the belt material 54 is formed into an annular shape (ring shape) and wound around the cross member 11, and the annular belt member 54 is fixed to the cross member 11 via an appropriate fixing fitting (such as a screw or a screw member). . On the other hand, the belt material 58 fixed to the engaging tongue 52 can be used as the growing material 30 by being hung downward.

  Since the belt members 54 and 58 used for the seat belt have a smooth surface, kelp seedlings (zoospores: male gametophyte / female gametophyte) floating in the sea are difficult to adhere. For this reason, it is preferable that a member (for example, a seedling net or the like) in which kelp seedlings are arranged in advance is fixed to the belt material 58, or a wound hole 59 where the kelp seedlings are likely to adhere at an appropriate interval in the vertical direction. Provide.

  The wound hole 59 has a size of about 3 to 6 cm in the vertical direction, for example, and is opened to the extent that seawater can flow while scratching the belt material 58 (the growing material 30) and exposing the resin fibers. Providing such wound holes 59 at appropriate intervals facilitates artificial seeding work of kelp seedlings. In addition, seaweed seedlings (marine gametes / male gametes / female gametes) in the sea tend to adhere to the resin fibers and gain a growth scaffold in the same way as kelp grown on rocks (so-called natural kelp) to grow kelp It can be made. The wound hole 59 should have a size that allows the kelp seedling to grow. The size is preferably set as appropriate depending on the environment of the sea to be cultivated (sea temperature, type of kelp) and the like.

  According to such a configuration, it is easy to attach / remove the growing material 30 (belt material 58). It is not necessary to remove the cross member 11 from the vertical member 20 and transport all of the cross member 11 and the growing material 30 to the hay, as in the past, and remove the growing material 30 (belt material 58) as many as the workable number. Can be carried to the sun and dried in the sun.

  The quality of the cultured kelp K can be improved as the time from harvesting to sun-drying is shortened. Therefore, even if a small number of people, drying treatment can be performed in a short time by transporting the growing material 30 to the slag. And the quality can be stabilized satisfactorily.

  The buoyancy body 40 used in the present invention may have any buoyancy that allows the cross member 11 to float on the sea surface S even if the weight of the kelp K growing on the growth material 30 increases, and the structure and shape are not limited.

  As a technique similar to the cross member (11) including the buoyant body (40), there is a course rope used in a swimming pool. However, the course rope for swimming has an emphasis on the wave-dissipating performance for extending the competitor's time, and the float inevitably has a complex structure that improves the wave-dissipating performance. However, as the buoyancy body 40 used in the present invention is given priority to securing buoyancy, it is desirable to use a buoyancy structure having a simpler structure than the course rope. This is to reduce the cost.
