Description

  The present invention relates to a deposit removal device for removing deposits from a rope of an aquaculture facility, and more specifically, a culture rope to which a young shellfish is attached when growing a shellfish such as an oyster or a scallop. The present invention relates to a deposit removing device used to remove deposits attached to a root net or the like suspended and held in the sea.

In recent years, there has been a shift from overfishing to aquaculture due to a decrease in fishery resources due to overfishing and overfishing. In particular, shellfish such as bivalves have been cultivated early on not only for food resources, but also for the purpose of securing accessories.
For example, in the cultivation of shellfish such as oysters and scallops, as shown in the schematic diagram of the aquaculture facility B shown in FIG. One end side of the root rope 101 is attached to each of the seafloor fixtures 100, and the girder rope 102 is attached to the other end side of the root rope 101 to connect the two rope tails 101. Then, the other end side of the suspension rope 104 attached at one end to the floating balls 103 at several places on the sea surface is attached to the girder 103, and further, the floating ball 103 is attached to the girder 103 itself so that the girder 102 is submerged in the sea. A large number of aquaculture ropes 105 to which juveniles C of shellfish such as oysters and scallops are attached are suspended from this girdle 102.
As described above, for example, Patent Document 1 discloses a shellfish cultivation facility that hangs and raises young shellfish in the sea.

JP 2000-102332 A

By the way, it takes at least two to three years to cultivate young shellfish in the sea and grow into shellfish, and during that time, a rope that supports the culture rope with shellfish attached in the sea, especially the seabed Shellfish such as mussels, seaweed, and other deposits adhere to the ridge net that is passed over from the water level to the support (suspension) water level of the shellfish. Then, the weight of the deposit gradually increases with the growth of shellfish and the like.
As a result, the ropes hang down to the seabed due to the weight of the attached matter, and part of the suspended ropes come into contact with the seafloor fixing device 100 made of concrete blocks due to the flow of seawater, etc. In such a case, there is a risk that the tail rope will be cut. If the rope is broken, the aquaculture facility will be destroyed and destroyed, so it is essential to remove deposits regularly.

Therefore, conventionally, for example, a block-shaped removal device divided into two parts, or a removal device in which one ring member is fixed and the other ring member is configured to slide along the root tail, etc. In order to remove the deposits attached to the rope.
However, in the removal device divided into two, when setting the root rope, the block body is connected with a connecting tool such as a bolt so as to sandwich the root rope, so that the apparatus is large and is set to the root rope. It was troublesome to attach and detach, such as detaching from the Neo rope.

  By the way, when setting the removal device on the rope, it is lifted up by a hoisting machine powered by a hydraulic type equipped on the fishing boat together with the fence, and the removal device is also moved up and down in the same way. Is done by.

  In the past, without the regular removal work, increasing the number of floats that support the tail ropes and shelf ropes in the sea and at sea level so that the tail ropes do not hang on the seabed due to the weight of the deposits However, increasing the number of floats is costly and increases maintenance costs for aquaculture facilities. Removal work to remove the kimono has become the mainstream.

  Therefore, the present invention was devised to solve the above-mentioned problems, and is easily attached to and detached from a rope to which shellfish, seaweed, and other attached substances are attached, and has a simple structure and allows the attached objects to be efficiently removed. An object of the present invention is to provide a deposit removing device that has been developed so that it can be removed.

In order to solve the above-mentioned problems, the present invention provides a deposit removing device for removing deposits from the rope of the aquaculture facility constructed by a rope (at least a root rope, a fence rope, etc.) in the sea,
A first ring member and a second ring member each having a rope connecting portion, and the first and second ring members are pivotally attached to a part of a ring circumference, It is characterized by being configured so as to overlap substantially concentrically with the pivoting portion as a fulcrum, and to be able to cross each other.

  Here, a hoisting rope is connected to the rope connecting portion on the first ring member side, and a hanging rope is connected to the rope connecting portion on the second ring member side. The rope connecting portion on the side of the first ring member is provided in a ring circumferential portion located on the substantially opposite side of the pivoting portion with respect to the ring center point of the first ring member, The rope connecting portion on the second ring member side is provided at a ring circumferential portion substantially the same as the pivot attachment portion. Furthermore, a stopper portion is provided on the first ring member side to receive the movement of the second ring member when the second ring member rotates coaxially with the pivoting portion as a fulcrum and overlaps in a coaxial manner. In addition, it is preferable to adopt a configuration in which the stopper portion is provided at a substantially intermediate portion of the ring circumference between the rope connecting portion and the pivot attachment portion.

Further, each of the first and second ring members includes a rope opening that communicates with the inside and outside of the ring when overlapping substantially concentrically with the pivoting portion as a fulcrum, and on the first ring member side. The rope passage opening is provided in a ring circumferential portion located substantially opposite to the ring circumference where the stopper portion is provided, and the rope passage opening on the second ring member side is provided with the pivot. When the first ring member overlaps substantially concentrically with the landing portion as a fulcrum, it is provided at a ring circumferential portion that coincides with the rope opening on the first ring member side . Further, of the first and second ring members, at least the rope passage opening portion on the first ring member side is provided with a rope break-off preventing portion, and the rope break-off prevention portion has one end side on the rope passage opening portion. A clearance corresponding to the thickness of the rope is secured between the rope and the rope opening, which is fixed in the vicinity, straddling the rope passage opening in the ring circumferential direction, and the rope opening on the other end side. It is preferable to adopt a configuration such as opening at a position deviating from the portion in the ring circumferential direction.

  The first ring member includes a circumferential member on a ring circumference, and the circumferential member passes through the stopper portion and the pivotally attached portion from at least the rope connecting portion side, and the first ring member. The ring center range is provided in a ring circumferential range reaching substantially the opposite side of the rope connecting portion. Further, the first ring member slides on the rope under the weight of the second ring member when the second ring member overlaps the pivoting portion as a fulcrum in a variable manner. It is possible to adopt a configuration in which a substantially U-shaped tow-through recess that is sandwiched in a movable manner is provided in a ring circumferential portion located substantially opposite to the rope connecting portion with the ring center point as a boundary. This is preferable.

According to such a configuration, in a state where the first ring member and the second ring member that are rotatably connected in a part of the ring circumferential portion are substantially concentrically overlapped, the sea surface ( Set the rope so that it adheres to the rope to which the deposits rolled up on the fishing boat). In this state, both the first and second ring members are lowered to the seabed along the outside of the deposit. At this time, the rope is made substantially vertical and has a pull-down rope connected to the rope connecting portion of the second ring member, so that the first and second rings are substantially coaxially overlapped. It is kept by the stopper part with which the 1st ring member is equipped, and can be quickly lowered to the seabed. The hoisting rope connected to the rope connecting portion of the first ring member is drawn into the sea as the first and second ring members descend.
In this way, both the first and second ring members are lowered to the seabed, and when the first and second charge ring members arrive at the seabed, the pulling rope is loosened and the hoisting rope is mounted on the fishing boat. Wind up with a hoisting drum. Then, the second ring member rotates by its own weight with the pivoting portion as a fulcrum, and overlaps the first ring member in a substantially cross-variable manner. This intersecting and overlapping state is arbitrary depending on the attached state of the attached matter.
Thereby, the deposit | attachment adhering to the leash is removed so that it may be stripped off from the leash by the intersecting first and second ring members as the hoisting rope is hoisted.

The deposit removing device of the present invention is configured as described above, and is set in a state where the first and second ring members are coaxially overlapped on the rope to which the deposit is attached, By moving both the first and second ring members up and down by a hoisting machine such as a hoisting drum, the first and second ring members that overlap with each other with the pivoting portion as a fulcrum overlap each other. Adhering deposits can be removed by peeling off the rope. Further, at this time, the crossover overlapping state of the first and second ring members can be changed to be small with respect to the pivot portion as a fulcrum, so that it is possible to continue the removal work of the deposits.
Thereby, it can be expected that the removal operation is performed efficiently.

During the removal operation, both the first and second ring members are rolled up to the sea surface by a hoisting rope that is tied to the rope connecting portion on the first ring member side, and again, the rope is piled up substantially concentrically. For example, when lowering both the first and second ring members toward the concrete block, for example, to a concrete block, it can be performed by a hanging rope tied to the rope joint of the second ring member . That is, when the hoisting rope is released and both the first and second ring members are supported on the hanging rope side, the first ring member has the stopper portion at the second pivot point with the second ring member as a fulcrum. It rotates so that it may contact | abut to the ring periphery of a ring member, and both the 1st, 2nd ring members overlap coaxially.
As a result, the first and second ring members can be quickly lowered to the fixing member made of a concrete block on the seabed without being caught by the adhering matter adhering to the rope, and the removal operation can be performed. it can.

In addition, by overlapping the first and second ring members pivotally (connected) so as to be pivotable about the pivot part as a fulcrum, through the tightness opening that leads to the inside and outside of the ring, Both ring members can be attached to and detached from the rope to which the deposit is attached. Further, at least one side of both the first and second ring members is provided with a tow slip prevention portion so as to straddle the tow rope opening in the ring circumferential direction. The rope placed in the second ring members is easy and does not come off carelessly.
Thereby, even if the leash is connected in a loop shape, it is possible to easily attach and detach such as setting and removing the first and second ring members from the leash.

  Moreover, the second ring member is provided with a rope passage recess corresponding to the thickness of the rope at the ring circumferential portion of the first ring member that overlaps with the pivoting portion as a fulcrum in a variable crossing variable manner. It is possible to remove the deposits from the surface of the rope almost completely.
