DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an undersea surface-deposited waste rope collecting apparatus according to an embodiment of the present invention will be described in detail.

4 is a perspective view for explaining a configuration of a bottom surface immersed waste rope collecting apparatus according to an embodiment of the present invention. And FIGS. 5 to 11 are a series of reference diagrams for explaining the functions and operations of the bottom surface sedimentation waste rope collection apparatus according to the embodiment of the present invention.

As shown in FIG. 1, the apparatus 100 for collecting bottom sedimented waste ropes according to an embodiment of the present invention includes a main body 110, a collection member 120, and a support ring 130, The composite rope 120 and the support ring 130 can be easily detached and lost to the water until they are pulled up once they are collected once.

Hereinafter, embodiments of the present invention will be described with reference to the components.

2, a plurality of collecting members 120 are installed along the lateral direction of the front end of the main body 110 to collect the first closed ropes, And a second supporting frame 122, and a rolling support 123.

The first and second latching tabs 121 and 122 have a circular arc-shaped body spaced apart from each other and hinged to each other. The first and second latching frames 121 and 122 are provided at their distal ends with folding protrusions 121a bent in a direction facing each other so as to prevent the collected ropes from being separated. The first giant protrusion 121b further projects so that the collected rope protruding from the inside of the bending protrusion 121a bent in the direction facing each other is not separated, A second macro protrusion 121c protruding from the inside of the rear end of the stopper 122 so as to remove the collected rope so as not to be separated from the first macro protrusion 121b and the second macro protrusion 121c, And a plurality of fine protrusions 121d which are formed in a smaller size than the first and second macro protrusions 121b and 121c and strengthen the frictional force so that the collected waste rope does not slip.

The second latching bracket 122 is elastically supported by a tension spring (not shown) provided inside, so as to be spaced apart from the first latching bracket 121. When an external force is applied, And is pushed toward the frame 121 so as to narrow the gap. 6, when the collection member 120 meets the bottom surface which is raised so convexly, the second latching frame 122 is naturally pushed toward the first latching frame 121 by the rising bottom surface, It is possible to flexibly cope with the bending of the sea floor.

The rolling support 123 of the collection member 120 is installed on the main body 110 and supports the rear end portions of the first and second latching frames 121 and 122 while rotating them It plays a role. 9, when the closed rope is collected between the first and second latching frames 121 and 122, the first latching frame 121 and the second latching frame 122 ) In the rolling direction, tension can be applied so that the closed rope is not released. In this way, the rolling movement of the first and second latching levers 121 and 122 by the rolling support 123 is the most important method for strongly holding the collected rope so as not to be released. The tension applied to the collected rope is more strengthened so as to make the closed rope more rigid so as to be more rigid, It is something that can be caught.

Furthermore, the first and second latching tabs 121 and 122 are configured to be rotated in a direction to narrow the gap between them by electric power. To this end, the main body 110 is provided with an electric motor and a reduction gear assembly connected to the hinge coupling shaft 122a. As described above, when the first and second latching frames 121 and 122 can be closed by electric power, when the collecting operation of the closed ropes along the bottom surface is completed, the first latching frame 121 And the second latching bracket 122 can be gripped so as not to be lost when the closed rope is lifted to the sea. Of course, it is preferable that the pivotal movement of the first and second latching levers 121 and 122 is performed in parallel with the rotation operation of applying the tension to the collected loose rope, .

The collecting member 120 configured as described above imitates the shape of a buckwheat having a structure that is difficult to escape once, and additionally, a restraining function by a tension action is added by rotation in the rolling direction. It is possible to reliably block the escape and loss.

The supporting ring 130 serves to support the waste rope so as not to be dispersed when the amount of the waste rope collected from the collection member 120 increases to the extent of overflowing to the rear side. The support ring 130 is rotatably coupled to the right and left ends of the main body 110 so that the support ring 130 is adjustable in angle. The support ring 130 includes a circular arc-shaped body 110 located at the rear side of the main body 110, . In addition, the support rings 130 are provided in a plurality, and the support rings 130 are formed in the form of a dome that is three-dimensionally opened by adjusting the rotation angle of the support rings 130, thereby supporting the closed ropes in a wider space. Here, it is preferable that the angle of the support ring 130 is adjusted by rotation of the support ring 130 by electric power. To this end, an electric motor and a reduction gear assembly (not shown) are built in the main body 110 to rotate the rotation shaft 111. At this time, the rotation shaft 111 is formed in a multi-stage superposed tube shape so as to independently rotate the plurality of support rings 130 and is coupled to each support ring 130. And the operation of causing the plurality of support rings 130 to unfold can be performed during the collection operation depending on the amount of the collected rope when the apparatus for underwater monitoring is installed and when the apparatus for underwater monitoring is not installed It is preferable that the control is performed so as to be performed simultaneously with the start of the collection work as shown in Fig. If such a plurality of support rings 130 are provided, it is useful when collecting a large amount of waste rope that is difficult to be handled by only the collection member 120 as shown in FIG. 8, and moreover, a large amount of waste rope collected as shown in FIG. The collected ropes are pressed to reduce the angle of expansion between the plurality of support rings 130 before being pulled up to prevent the release of the waste rope and the loss of the waste rope. On the other hand, as shown in FIG. 11, It is possible to support the lower side of the rope and cope with the release burden due to the weight of the closed rope lump. In addition, the supporting ring 130 is provided with a plurality of sharp non-slip projections 131 for drawing a closed rope so that the closed rope does not slip, so that the separation of the closed rope can be more thoroughly suppressed.

The main body 110 is coupled to the collection member 120 and the support ring 130 as described above and is provided with traction cable (CA) fixing rings 112 at both ends thereof, CA) to move along the seabed. The main body 110 has long left and right shapes and a plurality of rolling supports 123 of the collection member 120 are installed on the end surfaces thereof. The main body 110 is provided with an electric motor and a reduction gear assembly (not shown) connected to the main body 110 in a number corresponding to the rotation of the rolling support body 123 and between the first and second support frames 121 and 122, An electric motor and a reduction gear assembly (not shown) for rotating the rotation shaft 111 for rotatably supporting the support ring 130 are also incorporated.

In addition, a pair of skids 115 slid along the bottom surface of the main body 110 are installed below the main body 110. Thereby, the main body 110 can move more rapidly along the sea floor.

The operation and operation of the bottom surface immersed waste rope collecting apparatus 100 according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 5 is a first view of the underside bottom sedimentation waste rope collecting apparatus 100 according to an embodiment of the present invention, which is pulled by a traction cable CA and starts to move. At this time, the first latching frame 121 and the second latching frame 122 of the collection member 120 are maximally opened, and the plurality of support rings 130 are stacked in a stacked state, thereby reducing the volume as much as possible.

When the bottom surface of the seawater deposited rope harvester 100 meets a curved underside surface during the movement, the second support frame 122 elastically supported as shown in FIG. 6 rotates and flexibly responds. As the boat moves along the seabed surface, The amount of waste ropes RO dispersed on the seabed surface of the collection member 120 is gradually increased over the first and second latching frames 121 and 122 of the collection member 120 as shown in Fig. At this time, the plurality of support rings 130 stacked in a stacked form are rotated by electric power and spread widely in a dome shape.

8, the overflow ropes RO overflowed to the rear side of the collecting member 120 are guided by a plurality of support rings (not shown) 130, and is gathered in a lump form without being dispersed. At this time as well, the closed rope RO, which is initially laid between the first and second latching frames 121 and 122 of the collection member 120, is separated from the first latching frame 121 and the second latching frame 122 And is fixed in a state in which the ropes are still separated from each other, and they are bound to the rear ropes (RO) which are in contact with the rear ropes (RO) .

9, the first latching frame 121 and the second latching frame 122 are pinched to narrow the gap between the first latching frame 121 and the second latching frame 122, Strongly squeeze the closed rope. At the same time, by narrowing the angle between the support rings, even a large amount of waste rope stretched by the support ring can be stably held by applying pressure so as not to be detached.

10, the first loose frame 121 and the second loose frame 122 are rotated in the rolling direction so as to apply tension to the collected loose ropes RO, So that the closed loop ropes RO directly supported on the second latching frame 122 and the neighboring closed ropes RO are held in a stable state.

Thereafter, when pulling up the tow cable CA from the ship SH located on the sea, the bottom surface-deposited waste rope collecting apparatus 100 is suspended with a large amount of the closed ropes RO as shown in FIG. At this time, the collected ropes RO are held by the first and second latching frames 121 and 122 and the support ring 130 and are held in a state of being tensioned, Since the weight of the self-weight is relieved by the support ring 130 located at the lower side, it is lifted without being lost in the water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
