Detailed Description
The following provides a specific embodiment of the sliding plate on the trawl net on two sides of a single ship.
Example 1
Referring to fig. 1, a single-boat two-sided trawl includes two sets of identical sliding plates, specifically, a first sliding plate and a second sliding plate; a stem 1 of the fishing boat is provided with a support rod 3, the support rod is provided with a left adjusting pulley 4 and a right adjusting pulley 5, the left adjusting pulley is connected with an upper adjusting ring 47 and a lower adjusting ring 48 of a first sliding plate through cables, a large movable ring of the first sliding plate 6 is connected with the outer end of a net opening of a first trawl 8, and the inner end of the net opening of the first trawl is connected with a left foreboard pile 10 of the fishing boat.
The right adjusting pulley 4 is connected with an upper adjusting ring and a lower adjusting ring of the second sliding plate through a cable 2, a large movable ring of the second sliding plate 7 is connected with the outer end of a net opening of a second trawl 9, and the inner end of the net opening of the second trawl is connected with a right front side pile 11 of the fishing vessel.
The first trawl net mouth comprises a bridgewire floating ball 12 and a sill lead weight 13.
The first trawl 8 and the second trawl 9 are respectively arranged at two sides of the fishing boat 1.
The first sliding plate 6 and the second sliding plate 7 have the same size and are symmetrical in structure.
Referring to fig. 2, the first slide plate includes a main plate 51, a front wing plate 42, an upper wing plate 41 and a lower wing plate 44.
The front wing plate 42 inclines ten degrees outwards, and the main plate 51 is staggered ten centimeters inwards from the front wing plate 42 to form a diversion trench 43.
The two sides of the main board are provided with an upper wing plate 41 and a lower wing plate 44, the upper wing plate and the lower wing plate are connected with the main board in a welding mode, and the upper wing plate and the lower wing plate are welded to be inclined outwards by ten degrees.
The upper wing plate 41 and the lower wing plate 44 have the same size and symmetrical structure.
More than two floating balls 45 are arranged on the upper edge of the upper wing plate to keep the sliding plate horizontally upright in water.
The total buoyancy of the floating ball 45 on the upper wing plate is F, the gravity of the first sliding plate is G, F is larger than or equal to G when the sliding plate works on the surface layer of the water body, F is larger than or equal to G when the sliding plate works on the middle layer, and F is smaller than or equal to G when the sliding plate works on the bottom layer, and the buoyancy of the floating ball is adjusted to realize the purpose.
A main reinforcing rib 49 is arranged at the central horizontal position of the projection surface of the sliding plate, and a large movable ring 46 is arranged at the central position of the main reinforcing rib. Two parallel secondary reinforcing ribs 50 are arranged on two sides of the main board to connect the upper wing plate and the lower wing plate.
The utility model discloses with the rectangle slide device in the two side trawl net outsides of single ship, slide and rivers effect form to the outside tension when utilizing the fishing boat to navigate, the pulling trawl net mouth outwards opens to the water of warp is swept to the maximum bore, reaches the high efficiency fishing purpose. The utility model discloses it is simple and convenient to draw materials, and the fulcrum is few, simple structure, practical easy operation, and the floater plays to hang, adjusts the effect of slide dive degree of depth to make the slide perpendicular to the surface of water.
