Description
Technical field
The utility model relates to a kind of marine fishing equipment that belongs to, and specifically refers to a kind of buoyancy cover net using for light shelter net fishing boat.
Background technology
The operation fishing boat that at present, Central-South sand is fished for pelagic fishes westerly, mainly take light shelter net fishing mode as main, and the class of fishing comprises squid, trigger fish and a small amount of tuna.Current light shelter net fishing boat netting gear adopts plain net edge with net pendant, and after open on sea, under the drive of net pendant, whole throwing the net is umbrella.The method that netting gear is opened is one, four some arranged in dislocation fixed type steel truss freely-supported rocking arms end to end in ship both sides, on deck plane, building high vertical steelframe adopts rope system to pin down rocking arm; the length of rocking arm is captain 80%; its effect is cover net is strutted and cast net, so light shelter net operating type belongs to large eccentricity gravity operating type.For the existing potential safety hazard of light shelter net fishing boat, the Xie Yongqing researcher of Zhanjiang Sheng Lang marine fishing research institute has done ad hoc analysis, and the < < light shelter net fishing boat potential safety hazard of publishing an article is analyzed > >.The potential safety hazard of pointing out light shelter net fishing boat in article mainly concentrates on 5 aspects.1, on fishing boat deck, build high vertical steelframe, cause fishing boat center of gravity to be increased substantially, cause fishing boat antidumping performance greatly to reduce.2, the fixed freely-supported steelframe rocking arm of large span, owing to being to pin down by rope system, lacks rigidity braking and hydraulic pressure auto-lock function.If pin down hawser aging change not in time or when stormy waves is large rope be pulled off, free fulcrum rocking arm will with Lidar Equation freely swing closed with open, cause fishing boat disequilibrium.3, rocking arm, owing to being to pull expansion by rope system, lacking mechanical synchronization and launches function, if the rocking arm another side rocking arm that is stuck continues to launch on one side, the large eccentricity power of formation will cause the fishing boat sinking of toppling.4, adopt the cover net that covers hull bottom to carry out fishing operation mode, netting gear may cause fishing boat to run out of steam by winding screw oar.5, large eccentricity is opened the technical problem that the facility of casting net mates with fishing boat resistance to capsizing.In actual production, the potential safety hazard of front 3 each side performance is particularly outstanding, because mostly fishing boat is parking operation when the operation, screw does not rotate, operation is complete, and netting gear is received completely to the deck of ship, and therefore the probability of happening of the 4th aspect potential safety hazard is very low.And the potential safety hazard of the 5th aspect can overcome completely by reasonable computation when repacking.Potential safety hazard for front 3 aspects, the solution that Xie Yongqing proposes in article mainly contains: 1, adopt light-weight high-strength material manufacture with the synchronization telescope rocking arm of hydraulic pressure auto-lock function, replace fixed freely-supported rocking arm, impel rocking arm to save and pin down needs, therefore without build the structure of Gao Li on fishing boat deck, thereby fishing boat center of gravity is reduced greatly, strengthened fishing boat antidumping performance.2, adopt synchronization telescope rocking arm, avoided rocking arm to occur because asynchronous expansion causes fishing boat to turn over side sinking security incident.3, adopt hydraulic pressure self-locking rocking arm, with mechanical rigid braking, replace rope flexible braking, limited the freely swing personnel that injure and damage fishing boat facility of rocking arm when out of control.Seen from the above description, its solution providing is mainly the improvement for rocking arm, fishing boat still needs to stretch out very long rocking arm and covers net and strut and cast net when operation, its operating type still belongs to large eccentricity gravity operating type, and long rocking arm proposes very high requirement to the resistance to capsizing of ship equally.
Summary of the invention
For overcoming current illuminating cover net fishing boat existing potential safety hazard when the production operation, the utility model provides a kind of buoyancy cover net using for light shelter net fishing boat, adopt this buoyancy cover net fishing boat without rocking arm being installed and being built the structure of Gao Li on fishing boat deck, can guarantee that fishing boat center of gravity is not elevated, guarantee the steady safety work of fishing boat.
For reaching above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of buoyancy cover net using for light shelter net fishing boat, it is characterized in that: this buoyancy cover net comprises that one struts air bag and a cover net, the wherein said air bag that struts is circular ring-type, after inflation, its diameter is ship length 2-3 times, several fixedly stretch rings are set on air bag madial wall, at air bag bottom even, several vertical hanger rings are set, air bag is provided with inflation inlet;
Described cover net is a cylindrical netting gear with square, is provided with a long cylindrical net capsule on square, net capsule and circular square internal run-through, and on cylinder wire side, uniform some vertical net muscle, evenly fix several net muscle rings from top to bottom on net muscle; The fixing some net pendants in bottom of netting gear and the ring that closes up, at the bottom of netting gear, mouth rope is successively through each ring that closes up;
Strut air bag Yu Zhao Netcom and cross cover net withdrawing rope realization connection, net capsule is positioned at air bag top, square is distributed in air bag inner region, the cylindrical section of cover net is positioned at air bag below, one end of cover net withdrawing rope is connected with the net pendant of cover sieve bottom through the hanger ring of air bag bottom, the net muscle ring on cover net net muscle, and the other end of cover net withdrawing rope is connected with the winch on fishing boat.
After described airbag aeration, diameter is 60-130m, and the diameter of inflation rear gasbag cross section is 0.4-0.6m, air bag wall thickness 4-8cm, and central pressure maximum can reach 0.6MPa.
Described cover net diameter is consistent with the diameter after airbag aeration, and the height of described cover net cylinder wire side is 40-60M.
The buoyancy cover net using for light shelter net fishing boat that the utility model provides, it adopts air bag can effectively solve as cover net device for spreading the potential safety hazard that conventional mask net fishing boat adopts rocking arm support net to cause hull existence to be toppled, adopt air bag support net greatly to improve the stability of hull, the quickly retracting that is simultaneously conducive to netting gear, has greatly improved fishing efficiency.Conventional mask net is when throwing in, and netting gear integral body is laid on the water surface, and then the net on netting gear base pendant drives netting gear to sink, and whole netting gear is umbrella in sinking process, very high in the flight rate of the process Mesichthyes sinking.And the cover net that the utility model provides adopts cylinder sealing enclosure net structure, sinking, initial netting gear top is strutted by air bag, when the shoal of fish being lured hull around, fast netting gear is transferred, the net pendant of cover sieve bottom first drives the vertical subsidence of cylindricality etting, and its subsidence velocity is more faster than the fan-shaped subsidence velocity of conventional mask net, when square sinks to walking fan shape moving by the time, cylindricality net covers the shoal of fish, and the shoal of fish in cover net without flight possibility, has been improved fishing output substantially widely.This buoyancy cover web frame using for light shelter net fishing boat is new reasonable, production operation convenient, not only improved fishing efficiency, makes the general safety performance of fishing boat be greatly improved simultaneously.
