Description
Technical field
The present invention relates to the accessory system that a kind of euphausiid shrimp is fished for, specifically, be that a kind of krill continuation fishes for accessory system and device inhaled by pump, belong to euphausiid shrimp Fishing technology field.
Background technology
Global ocean fishery resources generally fail, and krill just starts the marine organisms of developing as marine site, the South Pole, its rich reserves, nutritive value and market are progressively developed.According to statistics, krill resource reserve conservative estimation total amount can reach 2.5 × 108 ~ 6 × 108 tons, and its catchability is about the gross yield of current global fishery.Day by day exhausted in current fishery resources, various countries are again under the background greatly developing sea fishery economy simultaneously, are of great significance the exploitation tool of krill resource.
At present, China's krill is fished for industry and is mainly carried out fishing for of krill with stern trawlnet form, trawlnet mainly puts down from after-deck by its operating type, krill is focused to after in trawlnet keed, after utilizing stern door frame to hang up together in trawlnet and keed thereof, is released by krill from keed, this net mode makes bottom krill severe crush in keed, also there is breakage in various degree at other positions, cause its quality to reduce, and cannot be at war with external high-quality krill.Meanwhile, trawlnet promotes and makes shrimping efficiency lower with the operation of putting net, and the labour intensity of artificial manipulation is comparatively large, and automaticity is lower.
Summary of the invention
The technical issues that need to address of the present invention are: when existing krill fishes for industry, need trawlnet to put down from after-deck, and need bull trawl more frequently to carry out promoting and the operation put down, make bottom krill severe crush in keed, the quality of shrimp is lower; The continuation of shrimping is simultaneously poor, and efficiency is lower, and labour intensity is also higher.
The present invention takes following technical scheme:

Further, inhale shrimp pump 6 to be connected by keed interface 4 with krill trawlnet afterbody keed part, guard shield upper trapezoid tapping also can bind keed simultaneously, dispersion pulling force is to improve the force-bearing situation of whole afterbody, trapezoidal perforate can also prevent from producing extruding when krill in trawlnet is instantaneous too much has little time suction, and krill can be discharged from trapezoid-shaped openings.
Further; inhale on shrimp pump motor protective cover and fixture is installed; calculate protective cover part accessory weight and be equipped with the suitable float of buoyancy to ensure that suction shrimp pump can guarantee figure mono-horizontal attitude under water, enabling suction shrimp pump can not unbalancely cause protective cover part to have a down dip to avoid the unobstructed suction krill of keed suction inlet.
Further, inhale on shrimp pump pump case and be provided with lifting interface 2, for being connected with steel wire rope, steel wire rope is connected to hull, carries out drift spacing to pump suction device; Ensure to inhale after working time and work complete shrimp pump can putting down and lifting from deck riding position to ocean simultaneously, and the length adjustment of loop wheel machine hoist cable can be relied on to inhale the underwater degree of depth of shrimp pump, ensure that inhaling shrimp pump can, with krill trawlnet keed at sustained height, enable suction shrimp pump aspirate smoothly.
Further, the end of described pump keed interface 4 is provided with anti-roll web frame 5, and described anti-roll web frame 5 prevents inhaling shrimp pump pump and is drawn through in journey because generation suction shrimp pump sling shaking when velocity variations or operation makes keed likely be involved in suction shrimp impeller of pump.
A device inhaled by the pump of fishing for for krill continuation, comprises and inhales shrimp pump 6, the suction inlet 3 armored pump keed interface 4 of described suction shrimp pump 6, and described pump keed interface 4 is evenly connected by multiple uniform hasp with keed, makes it accept keed equably and obtains pulling force; The end of described pump keed interface 4 is provided with anti-roll web frame 5, and described anti-roll web frame 5 prevents inhaling shrimp pump pump and is drawn through in journey because pump net combination miss enters to inhale in shrimp pump according to encystation net volume; Be fixedly connected with float 1 around described suction shrimp pump 6, described float 1 provides buoyancy to make pump suction device be suspended under water; Described suction shrimp pump 6 is provided with lifting interface 2, and for being connected with steel wire rope, steel wire rope is connected to hull, carries out drift spacing to pump suction device.
Further, described float 1 is fixed on to be inhaled on shrimp pump motor over cap, according to the buoyancy inhaled needed for the generation of shrimp pump protective cover part Gravity calculation float, select a considerable amount of float uniform with on protective cover according to buoyancy, ensure that inhaling shrimp pump can ensure attitude under water, offsets motor gravity and avoids this direction, position down; Described float 1 is PE ball float, and be bundled on motor protective cover, float is rounded or streamlined.
Further, described lifting interface 2 connects loop wheel machine peculiar to vessel, and auxiliary float is stablized and inhaled attitude inside seawater of shrimp pump and the degree of depth.
Further, described anti-roll web frame 5 forms cross or rice font by two steel pipes, is arranged in the middle of keed and pump keed interface 4.
Beneficial effect of the present invention is:
Make bottom krill severe crush in keed, the quality of shrimp is lower; The continuation of shrimping is simultaneously poor, and efficiency is lower, and labour intensity is also higher.
1) reduced and put net number of times, realized continuing to fish for, improve the efficiency of shrimping.
2) furthermore achieved that automation, reduce the intensity of crewman's work.
3) trawlnet keed and suction shrimp pump continue in water, drag shrimp and transport, directly direct for the krill in keed pump is drawn to deck and job shop, the form hung without the need to adopting stern door frame carries out hauling and unloading, great minimizing manual operation, reduce the arrangement etc. of netting gear, improve catching rate.
4) extruding of krill in keed can be reduced, rapidly krill can be transported to deck and job shop from keed, ensure the quality of krill and correlated product thereof.
5) significantly improve the krill mechanization of fishing for and automation, promote operating efficiency.
