Description
Technical field
The present invention relates to mesopelagic (200 meter Dao1000 meter Shui Shen) demersal fishes Fishing technology fields, more particularly, to a kind of controllable middle depth of network interface size
The finishing device and method of the subsea level stock of fish.
Background technique
Trawlnet is the movement using ship, and towing fishing gear advances in seabed or seawater, forces fishing gear by waters
The fished species such as fish shrimp crab enter net capsule, achieve the purpose that fishing.
Trawlnet may not only be applied to fishing fish, can be used for fishing siphonopods, shellfish and shell-fish；It may not only be applied to catch
The fished species that the depth of water only has several meters, tens meters are inhabited, fishing is can be used for and inhabites the deep-sea kind that the depth of water reaches thousands of meters.
But existing trawlnet has that network interface size is not easily controlled.
Summary of the invention
Goal of the invention of the invention be in order to overcome the shortcomings of that the network interface size of trawlnet in the prior art is not easily controlled,
Provide the finishing device and method of a kind of mesopelagic (200 meter Dao1000 meter Shui Shen) demersal fishes resource that network interface size is controllable.
To achieve the goals above, the invention adopts the following technical scheme:
A kind of finishing device of mesopelagic (200 meter Dao1000 meter Shui Shen) demersal fishes resource, including elastic ring, the trawlnet on elastic ring are set to bullet
Property circle top several floats, several weights set on elastic ring lower part, 2 support rods on elastic ring, be set to 2
Flexible axle on support rod；Flexible axle one end is with 1 support rod rotation connection, the flexible axle other end and on another 1 support rod
The shaft of motor connects, and flexible axle is equipped with several tapered inlets, and each tapered inlet connects with L shape drainpipe
Connect, each L shape drainpipe is vertical with flexible axle to be connect, the center line of each tapered inlet with corresponding L shape drainpipe
Lower vertical.
Ship drags elastic ring and moves forward, trawlnet expansion；When ship enters fishing areas, control motor drives flexible axle rotation,
Be gradually increased the angle between the center line and sea of each L shape drainpipe lower part, thus make the opening amplitude of elastic ring by
It is cumulative big, when the angle between each L shape drainpipe lower part and sea is within the scope of 75 ° to 90 °, each tapered inlet
When angle between center line and sea is within the scope of 0 to 15 °, elastic ring is expanded to maximum；
The direction of each tapered inlet is consistent with the direction of travel of ship, and water flow enters each tapered inlet, water
Stream is discharged from the shape drainpipe lower end L, and under the action of the downward impact force of water flow, elastic ring top is moved up, and elastic ring is opened
Mouth magnifies, and fish enters in trawlnet.
Therefore, the amplitude that elastic ring of the invention opens up and down is adjustable, to allow trawlnet according to fish density, ship
The speed of traveling automatically adjusts the network interface size of trawlnet, guarantees fishing efficiency, reduces production cost.
