Description

  The present invention relates to a gem coral collecting tool for collecting and collecting gem corals.

  With regard to reef-building corals, the number of deaths that are believed to be attributable to recent global warming is decreasing. In response to these circumstances, various reef-building coral reefs have been proposed. A coral reef nurture refers to a sediment (including structures that float in the sea) for rearing the offspring of a coral reef that has been placed or held in advance. A coral reef is formed by arranging and sinking a large number of reef-building coral growth reefs in which a large number of offspring is allowed to settle or are held.

  The patent document 1 makes the upper surface an inclined surface, forms the inclined groove of the inclination direction in the said inclined surface, and is a concrete block body which installed the support rod in the said inclined surface. A coral epidemic base composed of (Patent Document 1 [claim 1]) and a biological inhabiting block which is a block made of concrete is disclosed (Patent Document 1 [claim 3]). The coral reef nurturing reef disclosed in Patent Document 1 has an effect such that the uneven surface contributes to the establishment of the coral reef (Patent Document 1, [0006]).

  Patent Document 2 discloses a coral reef-growing reef (a landscaping block) which is made of hardened coal ash or concrete and in which a child strain (coral seed and sapling) is embedded. The reef-building coral breeding reefs are laid side by side in the transplanting water area to constitute a transplanting mound (Patent Document 2 [Claim 1]). The transplanting mound disclosed in Patent Document 2 can arrange reef growing coral reefs three-dimensionally according to the topography of the seabed, and various combinations of offspring embedded in each reef growing coral reef form a coral reef. It is said that this can be done (Patent Document 2 [0005]).

  By the way, like the coral reefs, the number of gem corals is also decreasing due to the effects of warming and overfishing. Therefore, in order to grow the gem coral, it is considered to grow the gem coral using the reef growing coral reef disclosed in Patent Document 1 or Patent Document 2. Specifically, the coral reef growing reef disclosed in Patent Document 1 or Patent Document 2 is planted with a child stock of a gem coral and installed on the seabed, and collected at a stage where the gem coral is sufficiently grown. However, there are problems in using the reef-growing coral reefs disclosed in Patent Document 1 or Patent Document 2 for growing and collecting gem corals.

  Gem corals are believed to inhabit the ocean floor at a depth of about 100m or so. From this, the reef-building coral growth reef disclosed in Patent Document 1 or Patent Document 2 in which the spruce of the gem coral is planted must be sunk on the sea floor of the water depth. However, the coral reef nurturing reef disclosed in Patent Document 1 or Patent Document 2 has no means for recovering from the water depth. For this reason, in order to collect the grown gem coral, it will be hooked and collected as usual. In this case, the coral reef growth reef becomes disposable, and it takes a long time to break the grown coral reef, which reduces the value as a decorative item, which is not preferable.

  Coral reefs may be used as disposable reef reefs without being required to be collected. However, on the premise that gem corals are collected, we would like to recover the used coral reefs to avoid excessive destruction of the habitat area. As described above, it is difficult to cultivate gem corals using the reef-growing coral reefs disclosed in Patent Document 1 or Patent Document 2. Therefore, we studied to develop gem corals and to collect them if possible without breaking them.

  As a result of the examination, fix the growth base on which the coral coral cubate is planted below the center of gravity of the frame, and set up a recovery frame that hooks the hook for recovery above the center of gravity of the frame. It is a gem coral collecting tool composed. The frame is configured by assembling a rod. The rod body may be made of resin or a resin-coated metal pipe as long as the required strength can be secured. However, from the viewpoint of reducing the projected area to reduce the resistance during sedimentation of the gem coral collecting tool while taking into consideration the corrosion during the setting period of the gem coral collecting tool, the rods constituting the frame have a corrosion allowance A solid structure with an added profile is preferred. The growth base is a block fixed to the frame in a state of being planted with gem coral, and may be a structure that does not drop out of the frame until the growth period of the gem coral elapses.

  In the gem coral collecting tool of the present invention, the growth base on which the coral coral is planted is sunk together with the frame, and the growth base is recovered together with the frame after the growth period of the gem coral. The collection frame is hooked with a collection hook so that the growth base can be collected together with the frame. By arranging the growth base below the center of gravity and the recovery frame above the center of the frame, the posture of the sedimented coral reef material is maintained at a position where the recovery frame is located above the growth base. Thus, the sunken gem coral collecting tool arranges the recovery frame above the frame surrounding the breeding base, and when the recovery hook is caught on the recovery frame, there is a fear that it contacts the grown gem coral of the breeding base. Eliminate

  For example, a hook for collection is attached to the lower end of a rope lowered from the ship into the sea, and is hooked to the collection frame by pulling it in the sea as the ship moves. At this time, the rope may come out of the collection frame while pulling while contacting the collection frame in advance. Therefore, the recovery frame may be configured to have stopper portions forming convex steps with respect to the hooking rod at both ends of the hooking rod extending horizontally. Even if the rope is put on the end while rubbing against the hooking rod, the rope is hooked on the stopper and can not be detached from the hooking rod, and the hook is hooked on the hooking rod.

  The recovery frame may be separately attached to the frame for fixing the rearing base, but a component of the frame located above the center of gravity of the frame may be used. Specifically, the recovery frame has a configuration in which a horizontal bar of the frame is used as a hook and a cross bar intersecting in the vicinity of both ends of the horizontal bar is used as a stopper portion. The frame is a rectangular frame based on a metal rod assembled in a rectangular shape, standing a metal rod serving as a pillar at four corners of the foundation, and bridging a metal rod serving as a beam and a girder to the pillar In the case, the hooking bar is a beam and a girder, and the stopper is the upper end of the pillar.

  In the case of collecting gem corals, it is preferable to use a gem coral collecting tool which can easily collect gem corals after hooking the collection frame and pulling it up. From this, it is preferable that the rearing base be a block or a plate in which a copulation of a gem coral is planted on the upper surface, and be freely detachable from the frame. The block or plate is made of, for example, concrete or mortar. As the attaching / detaching means, various conventionally known means can be used. For example, if the base side insertion hole penetrated in the growth base is communicated with the frame side insertion hole provided in the frame and the structure is tightened with a bolt and a nut tightened, the gem coral collecting tool is grown at the time of sedimentation and recovery. The base does not come off the frame and is preferred.

  The gem coral collecting tool of the present invention cultivates the gem coral and makes it collect reliably. In the past, gem corals were collected by chance by being caught by coral nets, so the possibility of collecting them was affected by chance and was low. Gem coral collecting tools ensure that corals can be collected because the sink position is specified. In addition, since the gem coral collecting tool is grown in a state where the gem coral is enclosed in a collection frame, and hooks are collected by hooking the collection frame provided in the collection frame, the gem coral is collected from breeding to collection. It is possible to collect gem corals with high risk of breakage and high commercial value. Thus, the gem coral collecting tool of the present invention has the effect of making the collecting of gem coral a stable commercial business.

  A recovery frame provided with stoppers at both ends of the hooking rod hooks the hook on the hooking rod so that the rope does not come off the both ends of the hooking rod. This eliminates the possibility that the hook will not catch on the recovery frame and fails to recover the gem coral collecting tool, thereby reducing the labor and time required for collecting the gem coral collecting tool. The effort and time required for recovery of such gem coral collecting tools lead to the effect of making gem coral collection a stable commercial business.

  The horizontal frame of the frame is used as a hooking bar, and the recovery frame with a cross bar that crosses near both ends of the horizontal bar as a stopper portion is completed if the frame is configured, so it can be separately manufactured or attached to the frame There is no need to Further, since the recovery frame is integrally formed with the frame, there is an advantage that it is possible to increase the strength and easily withstand an impact when hooking.

  A block body or a plate body in which a coral coral planted with gem corals is planted on the upper surface, and the removable growth base on the frame is made removable with respect to the frame so that the water tank with the baby stock until just before the sedimentation of the gem coral collecting tool Can be maintained in the state of the zygote, or can be removed from the frame integrally with the gem coral after collection of the gem coral collecting tool to collect the gem coral. In addition, the growth base, which is a block or plate made of concrete or mortar, also functions as a weight to shift the center of gravity of the frame further downward, and stabilize the posture of the settling gem coral collecting tool.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The gem coral collecting tool 1 of the present invention is configured, for example, as shown in FIG. 1, by fixing a growth base 3 to a base 21 of a frame 2 having a rectangular outer shape with bolts 32 and nuts 33. The gem coral collecting tool 1 of this example has a configuration in which six breeding bases 3 can be fixed to the frame 2, and three strains of baby coral offspring 34 are planted on each breeding base 3. For this reason, the gem coral collecting tool 1 of this example can collect 18 stocks of gem corals 35 if the child strain 34 can be successfully grown.

  As shown in FIG. 2, the frame 2 is constructed by assembling solid steel members having a rectangular cross section. Steel materials mutually adhere by welding. Steel materials have a size of 30 mm to 45 mm in consideration of corrosion allowance. In the frame 2 of this example, the steel material which is to be a total of six joists 22 consisting of three each in front and back is bridged over a base 21 in which steel materials are assembled in a 1000 mm square in a horizontal plane. Of steel material which becomes pillar 23 of height 500mm in addition to the above, cross the steel material which becomes girder 24 and beam 25 on the pillar 23 to the height which opened about 400mm to the steel material which constitutes the foundation 21 Is configured. The steel material serving as the joist 22 is provided with a frame-side insertion hole 221 through which a bolt 32 for fixing the growth base 3 is inserted according to the fixing position of the growth base 3. The frame 2 of this example configured by assembling such a steel material is about 150 kg.

  The recovery frame is configured such that the girder 24 and the beam 25 constituting the frame 2 are horizontal hooks, and the upper end portion 231 of the pillar 23 protruding upward from the corner where the girder 24 and the beam 25 intersect is a stopper portion . The rope 41 with the hook 42 attached to the lower end is hooked on the upper end portion 231 of the pillar 23 serving as the stopper portion located at the both ends even if the either end of the girder 24 or the beam 25 is detached I can not remove it. Thereby, the hook 42 at the lower end of the rope 41 can be reliably hooked on the girder 24 or the beam 25 (see FIG. 12 described later).

  As seen in FIG. 3, the growth base 3 is a rectangular cross section having a width of 60 mm and a height of 40 mm, and is a rectangular block body made of a rectangular concrete having a length of 500 mm. In the growing base 3 of this example, two base-side insertion holes 31 penetrating up and down are provided at positions close to both ends, and the stock reception holes 341 are provided on the upper surface between the base-side insertion holes 31 at equal intervals. The base side insertion hole 31 is in communication with the frame side insertion hole 221 of the frame 2 and the bolt 32 is inserted. The child strain receiving hole 341 is a recess for planting the child strain 34 cut from the separately collected gem coral.

  The rearing base 3 of this example is bridged perpendicularly to the joist 22 of the frame 2, and the base side insertion hole 31 is communicated with the frame side insertion hole 221 to pass the bolt 32 and the nut 33 is screwed to the bolt 32. It fixes to the frame 2 by doing. The fixing means of the bolt 32 and the nut 33 makes the growth base 3 detachable to the frame 2. Thus, the growth base 3 of this example was removed from the frame 2 and managed separately until immediately before the gem coral collecting tool 1 was sunk, or was removed immediately from the frame 2 after collecting the gem coral collecting tool 1 and grown. Can collect gem corals 35

  As seen from FIGS. 4 and 5, the frame 2 is asymmetrical in the vertical direction, and the steel members of six joists 22 are bridged over the base 21, so the center of gravity G is slightly lower than the upper and lower middle. Since the growth base 3 is fixed to the joist 22 of the frame 2, it is located below the center of gravity G of the frame 2 and is a heavy block because it is a block made of concrete. Further, since the recovery frame is constituted by the girder 24 or the beam 25 located above the center of gravity G of the frame 2, the recovery frame is located above the center of gravity G of the frame 2 and only by assembling steel material. It is relatively lightweight in comparison. Thus, the gem coral collecting tool 1 of the present example maintains the posture at the time of sedimentation in such a posture that the recovery frame is positioned above the growth base 3.

  The growth base 3 is, as seen in FIGS. 6 and 7, so that the bolt 32, the nut 33 and the child stock 34 of the gem coral fit within the space surrounded by the base 21, the column 23, the girder 24 and the beam 25. It is fixed to the frame 2. As a result, since the growth base 3 itself does not protrude from the frame 2, for example, even if the frame 2 collides with a rock mass at the time of sedimentation of the gem coral collecting tool 1, the risk of the growth base 3 being damaged is reduced. Further, since the distance between the base 21 and the girder 24 or the beam 25 is about 400 mm, the frame 2 of this example, for example, sinks the gem coral collecting tool 1 and There is no risk of colliding with child stock 34.

  The breeding and collection of the gem coral using the gem coral collecting tool 1 of this example will be described. The gem coral collecting tool 1 is loaded on the ship 4 and carried to the sinking sea area. It is desirable that the gem coral collecting tool 1 remove and carry the growth base 3. As a result, the offspring 34 of the gem coral can be transported in a state of being sunk in the water tank together with the growth base 3 while being planted on the growth base 3, and the weakening due to exposure to the outside air can be avoided. The growth base 3 is removed from the water tank just before dropping the gem coral collecting tool 1 into the sea 5 and fixed to the frame 2 with the bolt 32 and the nut 33.

  The gem coral collecting tool 1 having the growth base 3 fixed to the frame 2 in this manner is dropped onto the sea 5 with the growth base 3 down and the recovery frame up, as seen in FIG. The means for dropping the gem coral collecting tool 1 from the ship 4 to the sea 5 uses, for example, a crane mounted on the ship 4. The gem coral collecting tool 1 dropped on the sea 5 slightly shakes due to the influence of the resistance of the sea water and the ocean current, but basically the posture when dropped off, that is, the growth base 3 down, the recovery frame Sinking while maintaining the posture with the upper side, as it settles on the seabed 51 and sinks.

  A plurality of gem coral collecting tools 1 are sunk in a sunk area. The number of sinks of the gem coral collecting tool 1, the positional relationship between the sinks, and the difference in the direction of each gem coral collecting tool 1 at the sink position are free. In consideration of recovery by the hook 42 described later, for example, as shown in FIG. 9, the gem coral collecting tool 1 in the same direction may be arranged and sunk at the grid eye position. For convenience, in the illustration, the orientations of the gem coral collecting tools 1 are made to match, but in fact, they do not necessarily have to match. Even so, the gem coral collecting tool 1 arranged at the grid eye position can easily grasp the positional relationship to be sunk, and the hook 42 can be hooked to the girder 24 or the beam 25 to be easily collected.

  The gem coral collecting tool 1 is sunk for only the number of years (50 to 150 years) at which the offspring 34 grows sufficiently, and is recovered after the growth period has elapsed. The gem coral collecting tool 1 is collected by, for example, hooking a hook 42 of a rope 41 dropped from a crane (not shown) of the ship 4 to the sea 5 on a collection frame of the frame 2. The hook 42 causes the gem coral collecting tool 1 to approach from one direction while dragging to the sea bed 51 as seen in FIG. In this case, although the hook 42 may pass between the adjacent gem coral collecting tools 1, the case where the hook 42 approaches the jewelry coral collecting tool 1 will be described here.

  When the hook 42 approaches the gem coral collecting tool 1, as shown in FIG. 11, for example, the rope 41 abuts against the beam 25 of the frame 2 constituting the recovery frame (the rope 41 is the one of the gem coral collecting tool 1). Depending on the direction, it may abut against the girder 24 of the frame 2). In this state, when the ship 4 advances (refer to the white arrow in the right side of FIG. 11), the hook 42 is hooked on the beam 25. The gem coral collecting tool 1 of the present invention is pulled up from the seabed 51 by winding up the rope 42 in a state where the hook 42 is hooked on the collection frame of the frame 2 and is collected.

  Here, it is considered that the direction in which the hook 42 approaches the gem coral collecting tool 1 is not always orthogonal to the girder 24 or the beam 25 but rather approaches from an oblique direction in many cases. For example, as shown in FIG. 12, the rope 41 which is in contact with the beam 25 in a horizontal direction in a horizontal direction is aligned with the travel of the ship 4 (the diagonally lower right in FIG. 12, see white arrow). Shift towards the end of the (lower in Figure 12). However, the rope 41 is prevented from being detached from the end of the beam 25 by being caught by the upper end 231 of the pillar 23 as the stopper of the recovery frame.

  As described above, the rope 41 is caught on the upper end portion 231 of the pillar 23 serving as the stop portion of the collection frame, and once abuts on the beam 25 (or the girder 24) constituting the collection frame, the beam 25 (or girder 24) It does not deviate from (see FIG. 12). Then, the hook 42 is reliably hooked on the beam 25 (or the girder 24). Here, when the hook 42 is shifted toward the end of the beam 25, as with the rope 41, the hook 42 is caught on the upper end 231 of the pillar 23 which is a stop of the recovery frame. In this case, since the hooks 42 are also hooked on the upper end portions 231 of the pillars 23, they are less likely to be detached from the beam 25 (or the girder 24).

  Since the girder 24 or the beam 25 constituting the recovery frame is disposed above the frame 2 surrounding the breeding base 3, when the rope 41 and the hook 42 are caught on the girder 24 or the beam 25, the breeding base 3 is grown. There is no fear of coming in contact with the precious coral 35. This means that the branches of the grown gem coral 35 are not broken into the ropes 41 or the hooks 42. Thus, with the gem coral collecting tool 1 of the present invention, it is possible to collect gem corals 35 of high commercial value without breaking branches. This point is a great difference between the conventional coral fishing using a fishing net and the collecting method using the gem coral collecting tool 1 of the present invention.

  Once hooks 42 are hooked on the girder 24 or beam 25, there is no risk of the hook 42 coming off the girder 24 or beam 25 unless the ship 4 stops or slows down. And by winding up the rope 41, as shown in FIG. 13, the gem coral collecting tool 1 can be pulled up from the sea bed 51. When the gem coral collecting tool 1 moves away from the seabed 51, the load applied to the rope 41 further increases. Therefore, if fluctuations in the load can be confirmed, the gem coral collecting tool 1 can be recovered simply by stopping the ship 4 and winding the rope 41. Good.

  As shown in FIG. 14, for example, in the ship 4, the gem coral collecting tool 1 having been collected is removed from the frame 2 by removing the bolt 32 and the nut 33, and is further grown from the breeding base 3 Collect gem corals 35 In the breeding base 3 of this example, three strains each were planted with the offspring 34, but not all grow equally. However, the use of the gem coral collecting tool 1 of the present invention has an advantage of being able to collect the gem coral 35 grown to a considerable commercial value without breaking the branch, that is, without impairing the commercial value. This makes it possible to collect gem corals 35 into a stable commercial business.
