SU654224A1 - Device for catching aquatic animals - Google Patents

Description

In addition, winches are installed on the surface housings of the semi-submersible platform to move the side walls, partition walls and the bottom of the tank.

FIG. 1 schematically shows the proposed device, side view; in fig. 2 - the same in terms of; in fig. 3 - the same, view from the nose; in fig. 4 - the same cross section; in fig. 5 - the same, in axonometric projection.

The device comprises a container 1 of mesh material mounted on a self-moving semi-submersible platform 2 between the surface 3 and its underwater 4 hulls. The tank 1 is the working body of fishing, transportation and captive aquatic animals and contains side walls 5 and 6, partition walls 7, forming compartments for the captive content of captured animals, and the bottom 8, moving in the vertical and horizontal planes respectively along the guides 9 (shown are bridges for the side wall 5 and dividing walls 7) using remotely controlled winches 10 (winches for lifting dividing walls 7 are shown) located on the decks GOVERNMENTAL housing 3. The bottom 8 is reinforced at the level corresponding to the minimum sediment samodvizhuscheys semisubmersible platform 2.

Self-propelled with semi-submersible platform type 2 ship catamaran consists of two waterproof streamlined shape of underwater hulls 4, vertical streamlined streamlined shape in cross section of connecting columns 11, two surface hulls 3 and volumetric connecting bridges 12.

In the underwater hulls 4 there is a ship's power plant, propulsion, steering gear, ballast tanks and pumps, fuel, water and other supplies and equipment (not shown).

In the connecting columns 11, ladders are placed for descending into the underwater hulls 4, air intakes for marine engines, their exhaust pipes and other equipment (not shown).

Service, residential and other ship premises, the necessary shipboard systems and devices are located in the surface buildings 3. In the nose part of the right surface hull 3, the steering wheelhouse 13 is installed with a watch station for aquatic animals and remote control devices for the power installation of the device, a ballast system, and winches 10. A cargo crane is mounted on the deck of the left surface hull (on the drawing is not shown) and other cargo operations.

The device works as follows. Platform 2 is self-moving with semi-submersible platform and enters the area for catching aquatic animals in full ballast with submerged hulls 4 submerged under water. At the same time, side walls 5 and 6 and partition walls 7 are raised to the upper extreme position, and the bottom 8 is pulled to the left underwater case with the help of winches 10, which reduces the water resistance to the movement of the platform 2. They are in the same position on

standing, if the task of captive keeping in the structure of aquatic animals is not posed. In the area of catching set in working position mesh side walls 6 and the bottom 8, moving them in a vertical

and horizontal planes, respectively, with the help of winches 10, and in the formed container 1 they capture, maneuver and change the speed of the vessel, the pursued water animals. Then set to

working position mesh side wall 5, moving it in a vertical plane with the help of winches 10. After that, the animals are in a closed tank 1. Using dressing and other means, concentrate the captured animals in the stern of tank 1 and put in the working position closest to the group of caught animals mesh screen 7, and the mesh wall 5 is moved to the upper extreme position and repeat the operation of catching with a new group of animals. After filling all the compartments of the tank 1 with captured animals, the device is directed to the place of keeping

aquatic animals for reloading them to shore enclosures. To do this, a mesh corridor is installed from the bow of the device to the onshore aviary, the mesh side wall 5 is moved to the upper extreme position, water ballast is partially pumped out and the captured animals are distilled from the bow compartment of tank 1 along the mesh corridor to the coastal aviary. Then the first dividing partition 7 from the nose is moved to the upper extreme position and the captured animals are distilled from the second compartment, etc. By shifting the grid corridor to other coastal aviaries create an opportunity

haul catches of animals from each compartment capacity 1 device in your aviary. In order to accelerate the transfer of the captured animals from the tank 1 to the coastal aviaries by pumping out water ballast, the device reduces the draft and creates a trim for it.

For overloading individual individuals of captured aquatic animals by pumping out ballast water, the device is given a minimum draft at which the waterline passes at the level of the net bottom 8 when aquatic animals are practically on the dried net of the bottom 8, which ensures selective selective overload of individual animals without causing them injuries using bathtubs, stretchers, cargo cranes and other means.

The presence of a tank mounted on a self-propelled semi-submersible platform, excludes the physical and psychological trauma caused by catching, transporting and reloading aquatic animals, since it ensures that these operations are carried out without physical contact with animals. As a result, the number of suitable captured aquatic animals for research and development works with them in physiology and for human needs is increased.

Due to this, the use of manual manual labor for catching aquatic animals is also completely eliminated, and the laborious operation of reloading captured animals practically disappears, since the animals are transported in fishing gear - containers.

Safe conditions are created for the capture of aquatic animals and the possibility of catching, transporting and keeping other large and predatory aquatic animals.

In connection with equipping the tank with dividing partitions, it is possible to capture, transport, and encash the contents of aquatic animals with separate isolated groups or individuals.

Fixing fishing gear - a tank on a self-propelled semi-submersible platform with underwater hulls that provide increased seaworthiness to the device, reduces the dependence of the operation of catching water animals on the weather and the state of the sea, which reduces the time spent on catching. This also contributes to the increased maneuverability of the device type of the vessel catamaran with underwater hulls.
