SU91656A1 - Device for closing nets in horizontal plankton fishing - Google Patents

Description

To determine the quantitative distribution of it by the qualitative composition of the planktai, the morgue uses plantonpymchik networks of various systems. At present, REMs collect plates that lead tea by vertical fishing gear, benefiting from a vertical contactor. With pr01: the deeds from the horizons, the applied plankton nets do not close, due to which it is impossible to fish for ilikacton only from a well-defined horizon, as nlaikton from other horicules is captured.

The proposed device makes it possible to close the grids of the precursor heads with horizontal plankton fishing.

A distinctive feature of the proposed device is that the grid is an attachment for suspending it from the detachable track of the winch, consisting of a metal body connected to the side with a cable, and D | 1st side - with a loop for closing the grid, and from spring loaded swivel arm for illuminated and mesh.

FIG. 1 and 2 shows a predlata.me device.

The device includes a housing /, in the left part of which there is a lock 2 for securing the device to the winch cable. On the right side of the body there is a nipple in which lever 3 is located, rotates with an axis 4. screw 4. One horse of lever 3 ends with an ellis-like thickening. To wire the cable into the oval hole in the thickening 5 on the hinged side of the Ikeki 2. The other arm of the lever is made in the form of a hook 6 and under the action of the leaf spring 7 is pressed against the projecting lower part of the body. One end of the spring 7 is fixed to two cages to the body, and the other end of the connection with the holder 8 is U-shaped. The short end is holding

. passes through the hole holding the chip until it closes

planktonion mesh messenger load. The device is attached to the cable as follows: (arashok 9 is unscrewed to the full, the cheek opens and the cable is inserted inside the lock 2 and through the slot on the thickened part 5 of the lever 3 into the ovule hole. 2. For the closing of the plankton net in its middle part, Kapat 1 is passed through the rings 10. At the end of the rope there is a ring 12, which is connected with the device body J to the device body J. hardware to the ring 15. T To KaiK, on one cable, you can one time fix several plankton nets for horizontal fishing from different depths, then the messenger load 16, which is used to close the following plankton nets to the bottom of the next plankton grid, for each depth. from the baraba to the winch, it is passed through a counter-meter suspended on the wheel carrier. During the course of the vessel’s turn, the vertical position of the cable with the plankton nets fixed on it is provided by the suspended by the end of the rope with an oval weight of up to 100 kg.

Subject And s o r e te

A device for closure of nets at horizontal plankton, etc. is different. that, in order to close the grids at certain horizontal levels, each grid has a device for suspending it from the winch lifting cable, consisting of an L-metal core; mesh, and from a spring-loaded pivot arm mounted in the housing for hanging the mesh.
