Description

  The present invention is an underwater rope deposit that cleans deposits such as shellfish and algae attached to the rope while self-propelling the rope installed in the water to fix floating nets such as stationary nets, aquaculture fish nets and hulls. The present invention relates to a removing device.

  Floating bodies such as stationary nets, aquaculture fish nets, and hulls are suspended in seawater at predetermined positions by placing fixtures such as a hammer and a concrete block connected to the tip of the rope. If the floating body is left in the seawater for a long time, since the rope is also in the sea for a long time, deposits such as shellfish and algae adhere to the rope in the sea.

  In this way, if the deposit adheres to the rope, the rope becomes heavy and adversely affects the floating body. For example, in the case of a stationary net or a cultured fish net, there is a problem that the shape of the floating net is deformed. In particular, in the case of a stationary net, the number of ropes used is large, and thus the above problem is remarkable.

  In addition, since the bottom of the net is not fixed and is free, if it deforms due to tidal currents and comes into contact with the rope, it may be damaged by the attached matter of the rope. Also, if the rope becomes heavy with deposits, it may come into contact with the rocks on the seabed and break.

  Therefore, conventionally, various means as described below have been adopted.

  There is a device that scrapes off shellfish and algae attached to the rope by its own weight by passing a weight through the rope and dropping it into the water from the ship (refer to Prior Art 1, for example, Patent Document 1).

  Also, there is a device that scrapes off shellfish and algae attached to the rope by passing an annular metal fitting (shackle, etc.) through the rope, binding another rope to this metal fitting, and pulling the metal fitting from the ship (Prior Art 2). .

Moreover, the diver is used to remove the attached matter of the rope by a hammer, a cutter, and high-pressure washing (Prior Art 3).
JP-A-11-90378

  In the prior art 1, when there are many deposits or the angle of the rope is almost horizontal, the weight stops halfway, and the deep portion cannot be cleaned.

  In the prior art 2, since the rope is fixed on the seabed, the metal fitting can be pulled only to a certain extent, and the deep portion cannot be cleaned.

  The prior art 3 is a diving work, and the work cost is high. In addition, diving work in a deep part is difficult because there is a risk of diving disease.

  In addition, in the case of the peeling work by gravity or human power according to the conventional technique, it may take a long time for cleaning or a strong deposit such as a barnacle may not be excluded.

  An object of the present invention is to easily and quickly remove deposits over substantially the entire length of the rope regardless of the inclination angle of the rope.

  The rope insertion body of the present invention comprises a guide pipe fixed to the apparatus main body and having a predetermined inner diameter for guiding the rope, and the scraper member is detached from the apparatus main body when traveling in the backward direction. The apparatus main body is detachably provided.

  According to the present invention, the scraper member can be detached from the apparatus main body and can be made disposable, and after removing the deposits, the deposit removal apparatus can smoothly run in the backward direction.

  In the present invention, even a strong attachment such as a barnacle attached to a rope can be reliably removed and cleaned quickly over substantially the entire length of the rope.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIGS. 1-10 shows one Embodiment of the deposit | attachment removal apparatus which removes deposits, such as shellfish which adhere to the underwater rope based on this invention. In the present embodiment, as shown in FIG. 5, for example, an attached matter removing apparatus 1 for cleaning a rope 4 for fixing a cultured fish net 2 floating in seawater to the seabed 3 side will be described.

The inner diameter of the scraper portion 24 is set slightly larger than the diameter of the rope. As shown in FIG. 7, the scraper portion 24 is formed by inclining to the tip portions of the upper guide portion 21a and the lower guide portion 21b, even if it is a cylindrical portion having a slight length, as shown in FIG. Also good. In the case where the scraper portion 24 has a tapered cylindrical shape, there is no fear that the deposit 40 scraped off by the scraper portion 24 will remain between the scraper portion 24 and the rope 4 even if it enters between the scraper portion 24 and the rope 4. The rope guide body 5 is discharged from the large-diameter side opening.

  The support portion 22 includes a leg portion 25 fixed to the lower guide portion 21b and a flange portion 26 provided at a lower portion of the leg portion 25. The flange portion 26 is the upper surface of the mounting member 20 and the center in the longitudinal direction. It is fixed to the part with a bolt 26a or the like. Accordingly, each rope guide body 5 is located at the approximate center in the vertical direction of the apparatus main body 6 and the center in the horizontal direction with the small diameter side of the guide portion 21 facing the outside (front-rear direction) of the apparatus main body 6. .

  The driving device 8 includes a pair of pressing rotators 27 and 27 as traveling means for sandwiching the rope 4 from both sides, and driving means 28 such as a hydraulic motor and an electric motor that rotationally drive each pressing rotator 27. The pressing rotator 27 is a hollow elastic sphere made of rubber or the like, and the rotation shaft 28a of the driving means 28 is inserted through the center thereof so as to integrally rotate from below. The pressing rotator 27 can be appropriately filled with a liquid such as water in addition to air. Thus, by filling the pressing rotator 27 with the liquid, even if the deposit removing device 1 moves deep into the sea, the pressing rotator 27 is prevented from being deformed by water pressure. Reference numeral 29 denotes a fixing nut screwed into the tip of the rotary shaft 28a in order to prevent the pressing rotary body 27 from coming off from the rotary shaft 28a.

  A support base 30 is provided between the side members 19 and 19, and driving means 28 are attached to the support base 30. The support base 30 includes both side parts 31, 31 fixed to the side members 19, a pair of horizontal connection members 32 whose both ends are connected to the side part bodies 31, and a vertical bridge that is installed between the both side connection members 32. The driving member 28 is fitted between the vertical connecting members 33.

  Further, the driving means 28 is swingable and adjustable with a supporting means 35 such as a bolt as a fulcrum so that the pressing force with which the pressing rotators 27 and 27 hold the rope 4 can be adjusted. Moreover, an adjustment bolt 37 provided with a spring 36 that presses the driving means 28 with a predetermined force in a direction in which the pressing rotators 27, 27 approach each other is screwed to the both side bodies 31, 31. With this adjustment bolt 37, the pressing force between the pressing rotators 27, 27 can be adjusted.

  Next, the cleaning operation of the rope of the aquaculture fish net using the deposit removing device configured as described above will be described.

  First, for example, the bolt 26a that fastens each rope guide body 5 on the ship or the like is removed and divided into an upper guide portion 21a and a lower guide portion 21b, and a rope is provided between the upper guide portion 21a and the lower guide portion 21b. Then, the upper guide portion 21a and the lower guide portion 21b are fastened and fixed again.

  Further, the rope 4 is pushed between the two pressing rotators 27 and 27 against the respective elastic forces, and the rope 4 is held between the pressing rotators 27 and 27. At this time, the rope 4 is positioned substantially at the center of the pressing rotator 27 in the vertical direction.

Next, when the drive means 28 is a hydraulic motor, hydraulic oil is supplied to the hydraulic motor via the hydraulic hose H. When the driving unit 28 is a submersible motor, power is supplied from the power supply cable to each submersible motor. When the driving means 28 is actuated, the pressing rotator 27 rotates forward about the rotation shaft 28a (rotates in the direction in which the deposit removal device 1 travels on the seabed).
Therefore, the deposit removing device 1 is self-propelled along the rope 4 toward the seabed 3.

  During this travel, the scraper portions 24 of both rope guide bodies 5 slide on the rope 4, so that the deposit removing device 1 is guided along the rope, and the scraper portions 24 of the front rope guide body 5 are The deposit 40 is scraped off (see FIGS. 7 and 8). Even if the deposit 40 is a strong object such as a barnacle or a shell or a flexible object such as a seaweed, the scraper unit 24 scrapes and peels off the root portion of the scraper unit 24. Can be reliably removed.

  The deposit removing device 1 has the drive means 28 positioned below the rope 4 and the float 15 positioned above, so that the center of gravity can be lowered below the rope 4. The deposit removing device 1 There is no rotation around the rope in the sea. Therefore, the hydraulic hose H or the like does not get entangled with the rope 4, and the deposit removal device 1 removes the deposit 40 with the rope guide body 5 while traveling stably to the tip (the seabed 3 side) of the rope 4. be able to.

  After the deposit removing device 1 reaches the seabed 3, the deposit removing device 1 returns even if it travels along the rope 4 by reversely rotating the pressing rotators 27, 27. For this reason, by using the deposit removing device 1, the rope can be cleaned up to a deep portion safely and inexpensively.

  Moreover, even if there is a cut rope or the like near the seabed, the apparatus main body 6 prevents the cut rope or the like from coming into contact with the pressing rotator 27 or the like.

  The present invention is not limited to the embodiment described above. For example, as shown in FIG. 9, the rope guide body 5 may be provided so that the upper guide portion 21 a and the lower guide portion 21 b can be opened and closed by a hinge 43.

  Further, the diameter 24 a of the scraper portion 24 of the rope guide body 5 can be adjusted according to the diameter of the arbitrary rope 4. For example, as shown in FIG. 10, an optional inner diameter adjusting spacer 45 can be fitted between the upper guide portion 21a and the lower guide portion 21b in a replaceable manner.

  Moreover, in order to make traveling of the deposit removal device 1 more reliable, it is possible to provide means for preventing the rope 4 from being inadvertently detached from the pressing rotary body 27. For example, as indicated by phantom lines in FIGS. 2 and 3, safety bars 45 positioned near the pressing rotator 27 and above and below the rope 4 may be extended from the auxiliary frame 11.

  Although the case where two driving means 28 are provided according to the respective pressing rotators 27 is illustrated, a configuration in which both pressing rotators 27 are rotated by a single driving means 28 may be employed.

  FIG. 11 shows another embodiment of the present invention. The deposit removing device 1 shown in the present embodiment is of a crawler type. That is, the traveling means includes a pair of band-free crawlers 50 and 51 and rolling wheels 55a, 55b, 56a, 56b, and 56c that are supported by the chain cases 52 and 53 and rotate around the crawlers 50 and 51. Yes. In the chain cases 52 and 53, a pair of left and right link cases 58 and 59 constitutes a parallel link mechanism.

  The crawlers 50 and 51 are driven to rotate forward and backward by a hydraulic motor 60. One of the chain cases 52 and 53 is provided with a pair of support links 61 and 62, and the rope guide body 5 is provided at the tip of the support links 61 and 62. The rope guide body 5 is also provided on the other side of the chain cases 52 and 53 via support links 63 and 64.

  A spring 65 is connected between both the chain cases 52 and 53 so that both of the crawlers 51 and 52 come close to each other and clamp the rope 4.

  When the deposit removing device 1 is used, the rope guide body 5 is divided into two parts in the same manner as in the above embodiment, but the rope 4 is attached by attaching / detaching the link cases 58, 59 on the left and right sides. It is held between the crawlers 50 and 51.

  FIG. 12 shows still another embodiment of the deposit removing apparatus according to the present invention.

  For example, when the deposit removing device 1 travels back (runs in the backward direction after the removal of the deposit 40), the reverse rotation speed of the pressing rotators 27, 27 is high, or the deposit 40 can be completely removed. If not, the rope 4 that has passed through the pressing rotators 27, 27 may not be able to smoothly pass through the rope guide body 5, but may be clogged, bent, bulged, or the like.

  In the present embodiment, the rope insertion body is fixed to the apparatus main body 8, and a scraping disc 66 as a scraper member is detachably provided on the apparatus main body 8. Specifically, the rope insertion body is composed of a pair of guide pipes 5 a and 5 b having a predetermined inner diameter (formed with a margin larger than the diameter of the rope 4) for guiding the rope 4.

  The scraping aperture of the scraping disc 66 is formed substantially equal to the diameter of the rope 4. The scraping disc 66 is one in which a split member is integrally provided. The apparatus main body 8 has a holding portion 67 that is detachably fitted so as to prevent the scraping disc 66 from moving to the rear of the apparatus main body 8 and to allow the scraping disc 66 to be detached to the front of the apparatus main body 8. Is provided. The holding portion 67 is formed with a U-groove having a size larger than the diameter of the rope 4.

  Then, as shown in FIG. 12A, when the deposit removing apparatus 1 is run and the deposit 40 is scraped off by the scraping disc 66, the scraping disc 66 is held on the apparatus main body 8 side. The deposit 40 can be removed.

  As shown in FIG. 12 (b), when the deposit removing device 1 travels in the backward direction after the removal of the deposit 40, it is scraped off due to the frictional resistance between the scraping disc 66 and the rope 4. The disc 66 is configured to be detached from the holding portion 67 of the apparatus main body 6. In the deposit removing device 1, the scraping disc 66 is detached, so that the rope 4 cannot be scraped and cannot pass through the disc 66, so that it does not clog, bend, swell, or the like. Moreover, since the guide pipes 5a and 5b guide the rope 4, the deposit removing device 1 runs smoothly.

  Note that the scraping disc 66 may be a split member that is fitted into the holding portion 67 and disassembled when released.
