Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a divided arrangement structure and operating method of a net winch in a stern type otto roller.

BACKGROUND TECHNOLOGY Traditionally, in stern type otters and rollers, an integrated troll winch incorporating a warp drum (also used for winding up hand nets) and a center drum (for fishing) used to operate the casting net was installed on the deck near the center of the hull. It is installed in In addition, each of the ropes wound by each drum is configured to connect the hend and ground ropes to the onterboard via the reins, and to connect the warp to the onterboard, and to connect the warp and the reins with an idle wire. There is.

To haul a net with this winch mechanism, use a warp tram to rub the warp until the onterpod comes to the galose, at which point a stopper is manually placed on the onterpod, the hook is lowered to the cant outer plate, and the warp is separated from the onterpod. The play wire is connected to the warp, wound into the warp drum, the tip of the sleeve net is pulled into the warp winch, the fish is rubbed in, the tip end is raised, the tip end is lifted, and the fish is dropped into the fish hatch. However, in this work, the warp and reins must be removed from the otterboard, and the otterboard must be hung on the stern and lowered, which is one of the major bottlenecks in hauling nets.

Specifically, the board is approximately 3,000 meters long, has an area of approximately 15 m, and weighs over 5 tons, and requires approximately three workers on each side to raise and lower it. Because the otter board is large and there is heavy water, it takes time and effort to lower the hook, and it is dangerous because the work must be done at the very stern of the ship. be.

In addition, in conventional stern-type Otter trawlers, the trawl winch is installed close to the center of the ship as described above, so the warp passes through the top roller to the center of the ship, not only during trawling but also during net lifting. Because it is placed in a tensioned position on the fishing deck leading to the bottom, it is not desirable in terms of limiting the fishing space and ensuring the safety of the deck workers.

DISCLOSURE OF THE INVENTION The present invention is a stern type boat that saves labor in lifting nets by separating and changing the positions of each rub of the warp and the reins, and also improves work efficiency and ensures the safety of workers. The object of the present invention is to provide a divided arrangement structure and operating method for a net winch in an Otter trawler.

That is, in the present invention, by arranging the 99-inch warp winder on the deck on the port and starboard sides near the stern, the warp is not located within a wide range from the stern to the bow even during towing, and the warp is not located within a wide range from the stern to the bow. By hoisting the otter board with the left and right winches placed on the deck of the ship, the otter board is directly fixed to the stern cant shell by tension from the warp without being removed from the warp, and only the reins are removed from the otter board and installed on the deck near the bow. It is possible to haul nets by rubbing only the reins with the rein drum.

Therefore, with this invention, it is not necessary to manually hook and lower the otter board to the cant shell, and the netting work can be carried out by connecting the hand net to the reining winch and removing only the reins from the otter board. It is sufficient to have one worker at a time, and work efficiency can be improved because there is no need to hang the otter board on the stern or lower it, and it does not expose the workers to danger. Also, since the warp is only located within a short range from the side of the ship near the stern,
A larger fishing work space can be obtained, and deck workers can work more efficiently without having to worry about their undercarriage.

Example The following description will be made with reference to the drawings.

This stern-type Otter troller has an engine room 1 and a fish hatch 2 on the stern side, and a first engine room near the bow and in the center. A second fee/hold 3 is provided. On the deck are Puri and Kupost 4.5 used for net lifting work.
are planted on the stern side, slightly closer to the ship @ than I.4, and on the port and starboard sides, warp windings 99 inch 6 and 7 are lined up in a row slightly closer to the bow than the derrick boss 5 on the light side. A bridle drum 8.9 and a tip drum 10 are respectively arranged. An otter board 15.16 is connected to the warp 13.14 pulled out to the stern via the top roller 11.12 from the warp winding 99 inches 6°7,
Each otter port 15.16 has a 1'-line 17,1
8 to the hend and ground ropes 19a, 2(l
A body net 21 is supported by a, 19b, and 20b.

Hand net 17. l'8 is connected to the otterboard 15, 16 with an onterpentant. Also, each rein 17.1
8 can be auxiliary connected to the warps 13, 14 by idle wires 22.

In this mechanism, when hoisting a net, warps 13 and 14 are first wound in with the 99-inch warp winders 6 and 7 placed on the port and starboard sides. When the otterboard 15.16 comes to the stern cant shell (not shown), the drive of the warp winch is stopped and the onterboard 15.16 is warped to the 13.1
Fixed and supported directly on the cant outer plate with tension of 4. Next, after connecting the slack wire 22 to the rein drum 8.9 or pulling it out from the rein drum 8.9 and connecting the reins to the reins 17.18, only the reins 17.18 are moved to the onterpod 15.1.
Remove from 6. Thereafter, the rein drum 8.9 is driven to remove the reins 17.18 and the head.

Ground lobes 19a, 20a, 19b, 20b
Rub it in and bring the end of the sleeve net to the rein drum 8.9.

In this state, the fish can be dropped into the fish haunch 2 by operating the hollow drum 10 by the derrick boss 5 to pull the hollow end onto the deck, and further hoisting the hollow end with the derrick boss 4 as required.

On the other hand, when casting a net, after dropping the tip while moving forward, shake the rein drums 8 and 9, and when the reins 17.18 come to the stern, connect them to the onterpod 15.16 and remove them from the rein drums 8 and 9. By swinging the warp winding 99 inch 6, 7, the net can be finished casting and can be moved to the seine net.

As described above, according to the present invention, the onterpod is pulled and supported at the stern by the warp winch without being removed from the warp, so there is no need to lower the onterpod, connect it to the warp, or disconnect it, and only the reins are needed. By removing the warp from the onterpod, it is possible to carry out net hauling work, which reduces the number of workers, and allows the casting net work to be carried out quickly.It also minimizes the area where the warp is located on the fishing deck on the second deck. This makes it possible to improve workability and ensure the safety of stern and deck workers.
