Description
Technical field
The present invention relates to a kind of auxiliary system of euphausiid shrimp fishing, is a kind of krill continuation fishing specifically
Auxiliary system and its pump means, belong to euphausiid shrimp Fishing technology field.
Background technology
Global ocean fishery resources generally fail, and krill just starts the ocean life of exploitation as South Pole marine site
Thing, its rich reserves, nutritive value and market are progressively developed.According to statistics, krill resource reserve conservative estimation total amount
Up to 2.5 × 108~6 × 108 tons, its catchability is about the total output of global fishery at present.It is increasingly withered in current fishery resources
Exhaust, while various countries, again in the case where greatly developing the background of sea fishery economy, exploitation to krill resource has particularly significant
Meaning.
At present, China's krill fishing industry mainly carries out the fishing of krill, its operator in the form of stern trawlnet
Formula mainly puts down trawlnet from after-deck, and after krill is assembled into trawlnet keed, trawlnet and its keed are utilized together
After stern door frame is hung up, krill to be released from keed, this net mode causes bottom krill severe crush in keed, other
Also there is different degrees of breakage at position, causes the reduction of its quality, can not be at war with external high-quality krill.Meanwhile trawlnet
The operation for lifting and putting net make it that shrimping is less efficient, and the labor intensity artificially manipulated is larger, and the degree of automation is relatively low.
The content of the invention
The technical problem to be solved in the invention is：During existing krill fishing industry, it is necessary to by trawlnet from stern first
Plate is put down, it is necessary to the operation that more frequently bull trawl is lifted and put down so that bottom krill severe crush in keed, shrimp
Quality is relatively low；The continuation of shrimping at the same time is poor, and less efficient, labor intensity is also higher.
The present invention takes following technical scheme：
A kind of krill continuation catches auxiliary system, and shrimping trawlnet is arranged on ship stern side, the keed of trawlnet afterbody
Position sets pump means, and the pump means is connected with the rolling machine of ship stern, and the rolling machine is connected with shrimp separator；Institute
State pump means and provide hydraulic power by the pumping plant of ship stern；The pump means includes inhaling shrimp pump 6, the suction for inhaling shrimp pump 6
3 armored pump keed interfaces 4 of mouth, the pump keed interface 4 are uniformly coupled with keed by multiple uniformly distributed hasps, it is equably connect
Pulling force is obtained by keed；It is fixedly connected around the suction shrimp pump 6 with float 1, the float 1, which provides buoyancy, is suspended in pump means
Under water.
Further, shrimp pump 6 is inhaled with krill trawlnet afterbody keed part by keed interface 4 to couple, while shield
Upper trapezoid tapping can also bind keed, disperse pulling force to improve the force-bearing situation of whole afterbody, trapezoidal perforate can also be prevented
Only krill instantaneously excessively has little time to produce extruding during suction in trawlnet so that krill can be discharged from trapezoid-shaped openings.
Further, inhale and fixing device is installed on shrimp pump motor protective cover, calculate protective cover part accessory weight and match somebody with somebody
The standby suitable float of buoyancy with ensure to inhale shrimp pump can one horizontal attitude of guarantee figure under water, make suction shrimp pump unbalance will not cause to protect
Cover portion has a down dip being capable of unobstructed suction krill to avoid keed suction inlet.
Further, inhale and lifting interface 2 is installed on shrimp pump pump case, for being connected with steel wire rope, steel wire rope is connected to ship
Body, to pump means drift about spacing；Suction shrimp pump can be placed from deck after the completion of ensureing working time and work at the same time
Position putting down and lifting by crane to ocean, and the length adjustment of loop wheel machine hoist cable can be relied on to inhale shrimp and pump underwater depth, ensures to inhale
Shrimp pump can be such that suction shrimp pump smoothly aspirates with krill trawlnet keed in sustained height.
Further, the end of the pump keed interface 4 is equipped with anti-roll web frame 5, and the anti-roll web frame 5 prevents from inhaling shrimp
Suction shrimp pump sling shaking is produced when during pump pumping because of velocity variations or operation causes keed is possible to be involved in inhale shrimp pump
In impeller.
A kind of pump means for the fishing of krill continuation, including shrimp pump 6 is inhaled, the suction inlet 3 for inhaling shrimp pump 6
Armored pump keed interface 4, the pump keed interface 4 are uniformly coupled with keed by multiple uniformly distributed hasps, it is equably received
Keed obtains pulling force；The end of the pump keed interface 4 is equipped with anti-roll web frame 5, and the anti-roll web frame 5 prevents from inhaling shrimp pump pumping
During because pump net combination miss according to encystation net volume enter to inhale shrimp pump in；It is fixedly connected around the suction shrimp pump 6 with float 1, it is described
Float 1, which provides buoyancy, makes pump means suspend under water；The suction shrimp pump 6 is equipped with lifting interface 2, for connecting with steel wire rope
Connect, steel wire rope is connected to hull, pump means drift about spacing.
Further, the float 1, which is fixed on, inhales in shrimp pump motor protection cap, and protective cover part gravitometer is pumped according to shrimp is inhaled
Calculate float produce needed for buoyancy, according to buoyancy select a considerable amount of floats uniformly distributed with protective cover, ensure to inhale shrimp pumps can
Ensure posture under water, offset motor gravity and avoid the position from being directed downward；The float 1 is PE floating balls, is bundled in motor guarantor
On shield, float is rounded or streamlined.
Further, the lifting interface 2 couples loop wheel machine peculiar to vessel, and auxiliary float stablizes the posture for inhaling shrimp pump inside seawater
With depth.
Further, the anti-roll web frame 5 forms cross or rice font by two steel pipes, installed in keed and pump capsule
Among network interface 4.
The beneficial effects of the present invention are：
So that bottom krill severe crush in keed, the quality of shrimp are relatively low；At the same time shrimping continuation it is poor, efficiency compared with
Low, labor intensity is also higher.
1) reduced and put net number, realized lasting fishing, improved the efficiency of shrimping.
2) it furthermore achieved that automation, reduce the intensity of crewman's work.
3) trawlnet keed and suction shrimp pump continue to drag shrimp in water and transport, directly by the direct pumping of krill in keed
To deck and processing workshop, hauling and unloading are carried out without the form that stern door frame is hung, manual operation is significantly reduced, subtracts
Arrangement of few netting gear etc., improves catching rate.
4) extruding of the krill in keed can be reduced, krill rapidly can be transported to first from keed
Plate and processing workshop, ensure the quality of krill and its correlated product.
5) mechanization and automation of krill fishing are greatly improved, lifts work efficiency.
