Abstract
The utility model relates to the technical field of aquaculture, in particular to a shellfish dragnet with double-sided elastic teeth. The demersal shellfish dragnet with the double-sided elastic teeth is in a full-symmetric structure and is novel in structure, the shellfish dragnet can work normally with any surface in contact with the sea floor, and the situation that the web net face upwards and the back net faces downwards and the fishing cannot carried out can be solved when common shellfish net gear works in deep water and heavy flow areas. The shellfish dragnet can better show the reliability of underwater gesture and the fishing efficiency especially in deep water and heavy flow areas and heavy wind wave operating state. The operating time and the energy consumption are saved, the personal safety risk in the operating process is also reduced, meanwhile the safety factor of dragnet placing is improved, and the energy consumption is also saved. The shellfish dragnet with double-sided elastic teeth is of great importance in the equipment upgrading of bottom-dwelling shellfish aquaculture industry and has broad popularization and use values.
Description
Technical field
The utility model relates to technical field of aquaculture, is specifically related to a kind of two-sided elastic claw benthic mollusca trawlnet.
Background technology
At present, in China's Coastal Areas, the breed of shellfish development is rapid, and play stream propagation in the end is new in recent years fast, a kind of breeding way of outstanding effect of development that rises, and invests little, manageability, has the advantage of large-scale cultivation exploitation, and the development potentiality ten minutes is huge.Along with the progress of culturing science and technology; The depth of water of shellfish bottom sowing culture is constantly widened; Yet the netting gear that is used for shellfish culture process storage investigation at present and fishes for is greater than 50 meters the depth of water zone operation time, because the incomplete symmetry of netting gear each several part structure, under the effect of current and boats and ships towing tension; Turn over the net rate up to more than 30%, lose time and the energy.
In addition, arrive the seabed with the operate as normal attitude, promptly do not turn over net for guaranteeing netting gear.Operation to the staff when off line requires very strictness, and the volume and weight of netting gear danger concerning the staff of execute-in-place itself is very big, so, be badly in need of a kind of benthic mollusca safe, stable, simple to operate at present and gather netting gear.
The utility model content
The purpose of the utility model provides a kind of efficient, safe, stable benthic mollusca and gathers trawlnet.
The technical scheme that the utility model adopted is: a kind of two-sided elastic claw benthic mollusca trawlnet; Be full symmetrical configuration, comprise first three corner steady 1, preceding pick up shellfish device 2, after pick up shellfish device 3, drag guiding principle connecting ring 4, net bow 5, Vee formation fixed mount 6, sweep extra large iron chains 7, keed 8, auxiliary guiding principle connecting ring 9, the first ten shellfish device dead levers 10, the second ten shellfish device dead levers 11, keed seal mouth ring 12, the first net bow support 13, the second net bow support 14, the 3rd net bow support 15, network interface support 16 and the bracing frame 17 of draging.
Wherein, Draging guiding principle connecting ring 4 is welded on the net bow 5; Net bow 5 is welded on the network interface support 16; The welding first net bow support 13, the second net bow support 14 and the 3rd net bow support 15 on the net bow 5, the first ten shellfish device dead levers 10 are welded between the second net bow support 14; The second ten shellfish device dead levers 11 are welded between the 3rd net bow support 15, pick up before the distributed and arranged on the first ten shellfish device dead levers 10 and the second ten shellfish device dead levers 11 shellfish device 2 with after pick up shellfish device 3, between whiles the first ten shellfish device dead lever 10 and the second ten shellfish device dead levers 11 17 fixations of support bar are set.First three corner steady 1 is welded on the first ten shellfish device dead levers 10 and the first net bow support 13, and the auxiliary guiding principle connecting ring 9 that drags of the corner structure place welding of first three corner steady 1, Vee formation fixed mount 6 are welded on the second ten shellfish device dead levers 11 and the network interface support 16.Sweep extra large iron chains 7 and be connected between the network interface support 16, keed 8 is connected to be swept on the extra large iron chains 7, and keed 8 other ends are provided with keed seal mouth ring 12.
Pick up before said shellfish device 2 with after pick up shellfish device 3 perpendicular to the first ten shellfish device dead levers 10 and the second ten shellfish device dead levers 11, promptly vertical with trawlnet collection plane, seabed.
Before pick up shellfish device 2 with after pick up shellfish device 3 usefulness screw bolt and nut and be staggered and be fixed on the first ten shellfish device dead levers 10 and the second ten shellfish device dead levers 11 easy assembly and disassembly.
Before pick up shellfish device 2 total length greater than the length 6～8cm of the second net bow support 14.After pick up shellfish device 3 total length greater than the length 6～8cm of the 3rd net bow support 15.
Before pick up shellfish device 2 with after pick up shellfish device 3 free ends, an end that promptly contact with the seabed wraps up or entangles with the high-strength abrasion-proof elastomeric material, prevents benthic mollusca etc. is caused damage.
The said guiding principle connecting ring 4 of draging drags guiding principle connecting ring 9 and can separately use with auxiliary; When there is barrier in the seabed; 2 drag guiding principle connecting ring 4 with auxiliary drag guiding principle connecting ring 9 simultaneously with drag the guiding principle steel wire rope and be connected use, during the clear of seabed, 2 are draged guiding principle connecting ring 4 and drag the guiding principle steel wire rope and be connected use.
When the utility model uses, that the keed seal mouth rings 12 interspersed nettle bolts of keed 8 ends are tight.Netting gear drags guiding principle connecting ring 4 through 2 and drags guiding principle connecting ring 9 (using when there is barrier in the seabed) and drag the guiding principle steel wire rope and be connected with auxiliary; Two-sided elastic claw benthic mollusca trawlnet is in the towing process; Before pick up shellfish device 2 or after pick up shellfish device 3 benthic mollusca picked up the end off sea, netting gear is packed benthic mollusca in the net capsule 8 in the process of moving ahead.
Because the utility model is full symmetrical configuration, but the equal operate as normal in any one side contact seabed has solved common shellfish netting gear when the depth of water flows big regional operation, occur easily belly up, back of the body net can not adopt the situation of catching down.Especially operation more can show its reliability and stable adopting of attitude under water and catch efficient when big zone of depth of water stream and high sea.Promptly save activity duration and energy resource consumption, reduced the personal safety risk between operational period again.
The beneficial effect of the utility model is: adopt the holohedral symmetry design, and novel structure, but the equal operate as normal in any one side contact seabed, the operation when therefore off line requires fairly simple, has improved and has put the net safety coefficient, reduces personal risk; The utility model attitude stabilization does not under water turn over net, can save energy resource consumption and raising and adopt and catch efficient; The utility model is significant to the device upgrade of benthic mollusca aquaculture industry, has wide popularizing value.
