The invention relates to the fishing industry and can be used for catch of fish and other aquatic organisms involved .
A device (cone network), which is used on the Caspian sea for fishing of anchovy and ordinary kilka (), attracted by the light source. Melnikov V.N. - The device of fishing gear and technology of extraction of fish. - M: Agropromizdat, 1991. - 384 S.) It is a cone-shaped canvas, the base of which is fixed on a metal ring. A disadvantage of this device is the low size of the inlet and low speed of lifting gear, which leads to the care of a significant amount of fish from the zone of the fishery.
Also known device (inventor's certificate №2189140) where instead of the rings for disclosure of input use flexible spacers, placed radially, in the mouth of the trap. Spacers are dealt with when applying them in compressed air. Air is switched off the mouth of the trap formed, and it was chosen for 6 slings, to which the hoist rope. The disadvantage of this device is the need to be on the ship compressor or stock of cylinders with compressed air. In addition, when the sea is rough trap hits the Board, and may occur impulse hose or damage spacers. In addition, to control valves for delivery and air bleed applied electromagnetic drive. To do this, on Board a vessel should file another wire that complicates the operation of the device.
The task of the invention is increasing the reliability of the device and one-time increase of the catches by increasing the nip, back-up and factor to keep the hydrobionts.
This task is solved by the use of a rectangular frame has 1.5-2 times larger than the ring. Moreover, rectangular frame before the rise is formed by half, so its resistance when lifting a reduced several times, and it will not hurt overboard. For this purpose the frame, are fixed two ropes: lifting and descent (before there was one). In addition, the light equipment are regulated taking into account environmental conditions and peculiarities of behavior of aquatic organisms that will attract a greater number of hydrobionts.
Offers support for a catch of aquatic organisms, wherein to increase the harvesting and reliability capture of hydrobionts, its frame is manufactured in the form of a rectangle divided in the middle part of the beam, which is fixed light source, and, with the rise equaling half of the frame turn upward relative to the beam and closer; his tail rope connect the cords with the ends of beams, lifting rope - other slings to the midpoints of the most remote sides of the frame, and the parameters of light sources change depending on the changes of environmental parameters and behavior of the animals.
The invention allows to increase the efficiency of fishing tieback 40%, contribute to this: a large area of the frame, folding frame design, which before lifting up with the catch is formed by half and settings light sources change depending on the changes of environmental parameters and behavior of the animals.
On the drawing (Fig 1.) shows a schematic depiction of catching design. It consists of pyramid 1 facing downwards, folding frame 2, slings small 3, slings big 4, 5 rings, 6. The ends of the small sling 3 fastened to the ends of the beams 7, and slings 4 - over the edge of the frame 2. Half frame 2 can be folded up, turning around hinges 8 90 degrees. In a horizontal position halves frame 2 are hold with the help of angular end stops 9. Peak pyramid 1 is attached to the cylinder 10, equipped with a lid 11. To beam 7 fixed cartridge with a bulb, 12, from which the ship will stretch an electric cable 13. The straps 3 ring through 5 and swivel 6 enshrines the trigger Kanat 14, and the straps 4 - hoist rope 15. To the cylinder 10 connected exhaust the end of the 16th used to pull part 1 on Board a vessel for catch. On frame 2 sensor is fixed 17 of the instrument, the Supervisory approach of fish in the area of fishing, such as photocell.
Invention is as follows. After the detected concentrations of fish in the sea lowered auxiliary lamp-. Then on the rope 14 lowered into the water, part 1 back-up and all the device at the desired depth. The ropes 15 and 16 and cable 13 release with take advantage of slack (tension). Under the action of gravity cylinder 10 and frame 2 part 1 crushes and frame 2 is in the horizontal (open) condition. Include light source 12, the parameters of which are regulated with the help of a device installed on Board of a ship in the drawing is not specified) and switch off , maintain the device in the water until the accumulation of fish from the light source 12. This point will be visible on the indication of the instrument installed on the ship (in the drawing is not specified)associated with the sensor 17. After that the pickup lifted from the water for the hoisting rope 15, with frame 2 develops due to the rotation of its halves around the hinges 8. All the fish surrounding the source of light is captured part. Ropes 14 and 16 and cable 13 choose from take advantage of slack. After lifting the pick-up over the water, its pull on Board the vessel at the end of the 16th and, opening the lid 11, unload the catch on the ship. Then the cycle is repeated.
In inventions-equivalents increase in diameter and square ring trap prevents departure cargo boom. In addition, when rising traps most of the fish leaves the zone fishery. In the proposed design of those shortcomings, as the use of rectangular frame allows you to increase the size of the entrance into the trap, and with the addition of the frame is quick environment zones attract fish part. Lifting speed pick-up will be higher because of his resistance with closed frame will be several times less than in the existing construction. This will increase the number of cycles per night fishing. In addition, compared with the equivalent in the proposed design eliminates the need for compressed air hoses, flexible elements of the additional wire, which requires additional staff. Thus, the proposed design is more reliable and catchability. According to expert estimations, performance of catch will increase by 30-40%.
