Description

(54) DEVICE FOR PREVENTION OF FISH OUTLET

one

The invention relates to industrial fishing and can be used in trawling for fishing to prevent it from leaving the trawl hook.

A device is known for preventing the fish from escaping a trawl's knot, comprising a knot-shaped net insert secured at one end around the perimeter of the inlet knob and fitted with a hangover sling at the free end, and a device for tightening slidable strop 1.

The known device has a complex structure, providing for an electromechanical disconnector controlled from the vessel via a hydroacoustic communication channel.

The purpose of the invention is to simplify the design.

The goal is achieved by the fact that the fixture for tightening the bobber sling is made in the form of a rope loop located along the perimeter of the knot, connected by a running end to the movable boom strap end

For this, the running end of the cable loop is made of an elastic material, preIZ KUTKA TRALA

it is made of rubber, and is connected to the slipway through a detachable device rigidly fixed on the wing.

FIG. 1 shows a device for preventing fish from exiting the trawl; in fig. 2 - detachable device.

The device includes a net insert 1, which is made in the shape of a cage 2 and is fixed at one end around the perimeter of its inlet. The free end of the insert 10 ki 1 is provided with a slip strap 3.

Along the perimeter of the end part of the cage 2, where the catch accumulates, there is a rope loop 4, the section 5 of the running end of which is made of elastic material, mainly rubber, and connected

5 with the running end of the slipway 3.

On the cage 2 in the area of the insert 1 the detachable device is rigidly fixed, with which the rubber section 5 of the rope loop 4 is connected. Detachable device

2Q contains a piston mounted in the housing 6 with a rod 7, on the end of which a hook 8 is fixed for rotation. The piston is tucked in by a spring 9. On the one side, the hook 8 is equipped with a cable 10 connected
