Referring to fig. 1, the net-releasing winch is installed on a tail gantry 14, and a net-releasing frame 10 of a net-releasing tackle 15 extending backwards is fixedly arranged in the middle of the tail gantry 14 and used for releasing nets.

The fishing boat is also provided with a cab centralized control platform which controls the operation winch, so that workers do not need to be exposed beside the field winch, and personal safety can be relatively guaranteed.

The utility model discloses the concrete process that the operation winch was put the net to the netting gear, was dragged and was played does:

1) preparation before putting network

The net body of the net before net placing, the head line, the foot line and the like at the front end of the net are wound on the net drum winch 4, the G-shaped hook 8 at the front end of the head line is connected with the head line on the net drum winch 4, and the first G-shaped hook and the flat ring swing to be empty; the second G-hook disengages the "8" ring. All parts of the net are stacked and folded according to the sequence of launching, and the net bag is arranged at the tail chute port so that deck personnel can throw the net bag into the water. The net bag with a heavy structure needs to be pulled into water by adopting a special lifting hook and a net-releasing winch. The net board 8 is already hung on the net board frame or the tail door mast. The screen plate leading chain passes through a pulley hung on the screen plate frame or the tail gate mast; the otter board cross lines and the otter board cross line guide lines are arranged on two sides of the deck.

2) Net playing device

When the fishing boat selects the net placing place and determines to drag backwards, the boat advances at half speed, and the captain orders to place the net.

The stern staff pulls the net bag into the water by means of the net placing winch, and along with the rotation work of the net drum winch 4, the resistance of the water can drag the net body, the sinking net, the net sleeves and the empty net into the water, and at the moment, the net drum winch 4 can be switched to a high-speed gear due to the fact that the resistance for releasing the net tool is not large, so that the release of the net tool is accelerated, and the time is saved. The floats should be arranged uniformly on the water surface. The net drum winch 4 is then operated further to release the foot lines, and when the "8" -type ring 1 is released from the winch and reaches the middle rear part of the deck, the deck personnel connect the cross foot line G-type hook with the "8" -type ring, respectively. When the hand rope is released 1/2, the speed of the net roller is reduced and the speed of the boat is matched, so that the phenomenon that the shock force generated when the flat ring collides with the 8-shaped ring damages elements such as a sinker and the like due to excessive hand rope delivery is avoided. After the head line is loosened, the G-shaped ring is dragged away from the head line of the net roller winch 4 and is connected with the flat ring on the net plate lead chain, then the dragging steel is winched to bear the force, the net plate hook for fixing the net plate 8 is removed, and the net plate 8 is in a state of being loosened at any time.

When the net plates 8 are released, the vehicle runs quickly, and simultaneously the two net plates 8 are slowly released into the water, so that the upper edges of the net plates 8 just expose out of the water surface, and the two net plates 8 are separated from each other left and right under the impact of water flow. When the two net plates 8 are not entangled, the dragging steel is continuously released, and then the main winch 3 is adjusted to be in a high-grade state or is disengaged to allow the net to be freely released, so that the releasing speed is accelerated. When the first plus sign (50m or otherwise) of the drag steel reaches the screen frame pulley, the winch is stopped for about 10s to fully open the screen plate 8. In order to make the two mesh plates 8 flush, the main winch 3 brakes for several seconds when the dragging steel reaches the mesh plate frame sliding trolley for every number of 50m, and the operation skill can be properly lengthened. And after the steel hauling is released, locking the main winch 3 and turning to the trawl car speed.

3) Towing by pulling

Usually at a speed of 3.5-4kn for about 1.5-3 h.

4) Net hauling

The ship speed is reduced to half speed when the net is pulled up, simultaneously the main winch 3 winches and tows steel, and the main winch 3 can switch between high speed and low speed according to the actual condition of winching and towing steel, so that the working efficiency is improved. When the net plate 8 is about to discharge water, the twisting speed is reduced, so that excessive twisting is avoided, and the dragging steel and the connecting piece are damaged. When the net plate drag chain passes through the tail gate pulley, the main winch 3 stops winching and brakes quickly, and the net plate 8 is fixed by the net plate hook. Then the brake of the steel winch is released to loosen the drag steel, the drag steel is pulled back for 2-3m so as to separate the drag steel and the net plate 8, and a third G-shaped hook at the front end of the traveller is connected with the tail end of the trawl of the net roller winch 4. At the moment, the foot line is moved into a tail slideway, then a net roller is operated, the foot line, the hand line, the foot line and the net are all put into a deck through the tail slideway, when the 8-shaped ring on the foot line is put into the deck, a second G-shaped hook is removed from the 8-shaped ring, the net roller continues working, the foot line and the net are continuously reeled, when the net is shortened and reeled into a net roller winch 4, a traction steel wire rope of a Gilson winch 5 is used for flatly dragging the net sleeve and the net body in sections according to conditions, and the net roller winch 4 is matched with reeling. In the process of winding the net sleeves and the net body, the vehicle can be stopped and slowed down as required to avoid the net from tangling the propeller. When the net bag enters the deck, the bag net is lifted by the same-bag net winch 6 through a steel wire rope of the gate mast, the hydraulic door is opened, the binding rope of the bag net is untied, and the catch enters the processing room.

5) Cab integrated control

The steps 1) to 4) can be operated by centralized remote control of the cab, and the captain is organically coordinated with the control of ship navigation, so that the working efficiency is improved, and the oil consumption is saved.
