Description

TECHNICAL FIELD The present invention relates to a technique for cleaning aquaculture girders, and more specifically to a cleaning device capable of cleaning the main line of aquaculture girders on the sea during an aquaculture period.

Aquaculture digits are marine facilities for cultivating scallops, oysters, kelp, wakame seaweed, sea squirts, and the like. As shown in Fig. 1, the aquaculture girder is provided with a thick rope called a trunk line, to which are connected at regular intervals a rope for suspending aquaculture baskets and a rope for hanging scallop ears. . Both ends of the main rope are fixed to concrete blocks, iron anchors, driven anchors, etc., and are stretched in the sea by a plurality of connected floats.

In recent years, large-scale aquaculture in the open sea is becoming popular, and aquaculture girders are becoming larger. With large aquaculture girders, it is not easy to wash the main line on land, and replacement of the main line requires diving work. Therefore, since the trunk line is installed in the sea almost all year round, it becomes a suitable habitat for marine organisms, and foreign substances such as shellfish and seaweed other than farmed products propagate in large quantities, hindering the farming work. . In addition, when suspending a new rope from the trunk line installed in the sea, make sure that the thin rope is securely fixed to the trunk line and that the marine organisms that are the source of the release of seeds do not remain. Before tying the rope, it is necessary to thoroughly clean the main rope of foreign matter. However, the main rope is 200m long and has floats attached at regular intervals, so it is not easy to clean.

The currently used cleaning method is a method using a so-called "rocket". The rocket, as shown in FIG. 2, is a pipe-shaped cleaning tool having a through hole through which the main rope passes, and two parts A and B sandwich the main rope. The diameter of the through-hole is set to a size that allows the main rope to pass through but does not allow foreign matter adhering to the surface of the main rope to pass through. A main line lifted from the sea is stretched between two girder mobiles installed at a distance on the ship, for example, by passing the main line through a through hole of a rocket fixed to the hull of the ship and propelling the ship forward. , the foreign matter is scraped off from the main rope at the entrance of the through hole.

However, since the rocket cannot pass through the points where the floats are connected or where the rope is tied, the rocket cannot be used while the cultured products are suspended (usually about six months to one year). cannot be washed using It is possible to stop the ship when the rocket reaches the knot of the main rope, remove the rocket from the main rope, and attach the rocket again at the point beyond the knot, but the work is extremely complicated. is. On the other hand, if the through-hole is too large, part of the foreign matter will remain in the main rope without being removed, and if the through-hole is too small, the through-hole will be clogged with foreign matter.

Patent Literature 1 is a technology in common in that it cleans a long object, although it is in a different technical field. This technology relates to a device for cleaning dust adhering to the side surface of a monorail track girder. It cleans the side surface of an immovable track girder with high-pressure water from a water jet nozzle that moves vertically and horizontally while rotating. .

At the time of washing, the main rope R is pulled up from the sea and passed between girder movers provided on the edge of the ship S at the front and rear (FIG. 4(a1)). The main body 10 is arranged so that the rotating rollers 14a, 14b rest on a main rope R that is passed between the spar movers. The main rope R loosens when the ship S sinks during washing (FIG. 4(b1)) and tightens when the ship S floats (FIG. 4(a1)). If the height of the main body 1 is fixed and the main rope R is in a stretched state so that the main rope R is within the injection range of the cleaning liquid of the rotary injection nozzles 16a and 16b, the ship S will sink. If the main rope R is loosened in , there is a possibility that the main rope R may be out of the injection range of the cleaning liquid. Therefore, the device 1 is configured so that the main rope R passes through the injection range of the cleaning liquid even when the ship S repeatedly floats and sinks due to the waves, by moving the main body 10 up and down according to the movement of the ship S. It is

When the main rope R is loosened (FIG. 4(b1)), the main body 10 placed on the main rope R descends under its own weight, as shown in FIG. 4(b2). At this time, the body support column 34 moves downward between the upper facing rollers 38a and 38b and between the lower facing rollers 39a and 39b. On the other hand, when the trunk rope R is stretched (FIG. 4(a1)), as shown in FIG. move to As described above, in the apparatus 1, the main body 10 moves up and down corresponding to the vertical movement of the main rope R, and the relative positional relationship between the main body 10 and the ship S is automatically changed. , the main rope R is always guided by the rotating rollers 14a, 14b within the spraying range of the cleaning liquid of the rotating spray nozzles 16a, 16b.

The attachment portion 30 is not limited to the configuration of this embodiment. Mounting portion 30 may be, for example, a link arm mechanism comprising a plurality of arms rotatably linked to each other and hydraulic dampers that restrict movement of the arms. For example, the link arm mechanism includes a first arm having one end attached to the ship S, a second arm having one end attached to the body 10, the other end of the first arm and a second arm. A third arm rotatably connected to the other end of the arm may be provided, and each of the first arm and the second arm and the third arm may be connected by a hydraulic damper. The control force of the arm movement by the hydraulic damper is designed so that the main body 10 placed on the main rope R can move up and down by its own weight in response to the vertical movement of the main rope R.

The apparatus 1 preferably further includes a culture material guide section for guiding culture material having a size larger than the entrance to the internal space 11 (trunk entrance) so as to pass through the exterior of the main body 10 .

As shown in FIG. 3, the sliding plates 18a and 18b are connected to the front portions 181a and 181b provided so as to protrude in a semicircular shape in front of the cases 12a and 12b, and the lower ends of the front portions 181a and 181b. , lower parts 182a and 182b extending in the front-rear direction under the internal space 11, and rear parts 183a and 183b continuous with the rear ends of the lower parts 182a and 182b and extending obliquely upward.

FIG. 5 is a schematic diagram showing the movement of the device 1 when passing through a location where the float F is connected to the main rope R. As shown in FIG. When the main rope R is passing through the internal space 11 of the device 1 (Fig. 5(a)), a float F with a size larger than the entrance to the internal space 11 approaches (Fig. 5(b)), F hits the front portions 181a, 181b of the sliding plates 18a, 18b arranged in front of the device 1 (FIG. 5(c)). Floating ball F hitting front parts 181a and 181b moves downward along front parts 181a and 181b, and moves rearward along lower parts 182a and 182b (FIG. 5(d)). The main body 10 rises when getting over the float F, the main rope R separates from the rotating rollers 14a and 14b ((d) in FIG. 5), and the part where the float F is connected to the main rope R can be easily moved. (Fig. 5(e)) Therefore, if the device 1 is used, it is possible to continuously wash without interrupting the work even in a place where aquaculture materials such as floats F are present.

In the present embodiment, the sliding plate has a shape in which only the front portions 181a and 181b protrude forward in a semicircular shape, but the shape is not limited to this. In another embodiment, for example, as shown in FIG. 6, the sliding plate has a shape in which the rear portions 183'a and 183'b protrude not only in front of the main body 10 but also rearward in a semicircular shape. can do. By forming the sliding plate into such a shape, it is possible not only to move the ship S forward for cleaning, but also to move it backward for cleaning. In still another embodiment, the front portions 181a and 181b may be formed in a shape that protrudes forward in a quadrant arc shape continuously from the lower portions 182a and 182b instead of projecting in a semi-arc shape.
