Phage. 2

The device contains a tank (Е) 2 for water located on the receiving vessel at a height from its bottom 3 to the waterline 4, and a transport highway 5, the inlet section 6 of which is perforated and placed inside Е 2, as well as a mechanism for stabilizing the water level in Е 2, comprising a pipe 14 connected to the latter by the type of communicating vessels and a float 16 arranged therein, which, through a cable 15, a flexible element 19, a stepped rail 20 and under 7874

spring arms 23 and 24 are connected with controllers 21 and 22 for switching on the speeds of pump drives 11 and 12; Pump 11 is used to pump water from tank 2, and pump 12 to supply water to a water supply nozzle installed in on fishing gear. In the course of operation, depending on the water level in E 2, the pump 11 or pump 12 is turned on, as a result of which either the water intake from E 2 increases or the water supply to the nozzles increases. 3 il.

The invention relates to fish industry, namely, devices for continuous fishing, and can be used in the design and construction of fishing schemes for fishing of all types of commercial fish and other water bodies in the surface layers of water and at depths up to 150 meters.

The chain of the invention is to provide continuous transportation of large objects to the receiving vessel when fishing their dense concentrations.

The described device makes it possible to catch highly dense accumulations of fish, transporting it in a stable mode, which leads to an increase in the duration of continuous trawling and a decrease in energy costs. The device can also be used for mechanized transshipment of large fish from a purse seine into the hopper of a receiving vessel.

 FIG. 1 depicts the writing device, a general view; in fig. 2 shows a water tank with a mechanism for stabilizing the level of water therein; in FIG. 3 - intake cone with water supply nozzle.

The device for the continuous fishing of aquatic organisms by towing and receiving 1 vessels consists (Fig. 1 W 2) of a tank 2 for water placed on the receiving vessel 1 in the space from its bottom 3 to the waterline 4, the transport line 5, the lower section

6 which is perforated and located inside the tank 2 mounted on the catching part of the catching tool of the intake cone 7 communicated with the help of the pipeline 8, the flap 9 and the docking device 10 with the transport main 5 installed on the vessel 1 of the pumps 11-13 and the stabilization mechanism the level of water in the tank 2, which includes a pipe 14 connected to the tank 2 by the type of communicating vessels, and freely placed in the latter on the cable 15, the float 16, while the cable 15 is passed through the block 17 and fixed at its free end en load 18, rigidly connected to the flexible element 19, in which the step rail 20 is integrated, and contacting with the controllers 21 and 22 for switching on the speeds of the drives of the pumps 11 and 12 by means of spring-loaded levers 23 and 24. The flexible element 19 can be made in the form of a chain or cable and passed through the upper 25 and lower 26 blocks.

The suction port 27 of the pump 11 is connected to the water tank 2, and its pressure port 28 is in communication with the outboard discharge system. The suction pipe 29 of the pump 12 serves to collect the seawater, and its pressure port 30 is connected to a water supply nozzle 31 mounted into the intake cone 7 perpendicular to its longitudinal axis (FIG. 3). Inside the transport highway 5 is installed

sectional tray 32; the pump 13 is connected to the water tank 2 by means of the suction pipe 33, and its pressure pipe 34 through the distribution mechanism 35 serves to sequentially supply water to the section of the tray 32 through the pipes 36. In addition, the section tray 32 is equipped

collector 37 for collection and disposal I

water overboard, and the vessel has a bunker 38 for receiving fish.

The float 16 is made in such a way that its strength of force exceeds the frictional forces of all kinematic links connecting it with controllers 21 and 22, for which it is made of a layer of material with positive buoyancy and is attached to it with a metal plate. The blocks 25 and 26 are mounted on the frame 39. The height of the container 2 from the bottom 3 of the vessel 1 to its waterline 4 is selected on the one hand, and the drainage of the pipeline 8, on the other hand, is prevented from drying.

The device works as follows.

Tugboats and a receiving vessel 1 carry out continuous fishing. On tugboats, the device sends a signal at the time of recording the indications. At the receiving vessel 1, a signal is received, the pump 11 is turned on and the lever 23 is inserted against the stop of the stepped rail 20. At this moment, the controller 21 turns on the third speed (full rotation) of the pump 11, which through the suction port 27 pumps water out from the bottom, 3 to the waterline 4, overboard the vessel 1, where the water enters through the perforations of section 6. At the same time, under pressure, water flows from the pipeline 8 through the docking device 10, the water-perforated section 6 of the transport line 5 to the container 2. The lever 23 is installed It is also on the stop of the stepped rail 20. However, the controller 22 is set at zero and does not give a signal to turn on the pump 12. Then turn on the pump 13 and take water from the tank 2 through the suction inlet 33 and feed under pressure through the pressure pipe 34 and the distribution mechanism 35 into tubes 36 associated with

sectional chute 32, for transporting fish by pressure jet in sequential order along transport line 5 to hopper 38.

A tight streamer to the fish that gets into the intake cone 7 of the fishing gear does not have time to pass through the mouth of the pipeline 8 and under the influence of the incident flow of water lies and underpressures in the intake cone 7. During this period the water flow in the pipeline 8 sharply decreases and the water level in tank 2 falls. Together with the fall of the level

water in the pipe 14 is lowered by the float 16, bypassing the cable 17 through the cable 15, the latter moving the weight 18 fixed on it and the flexible element 19, pulling it through the blocks 25 and 26. The flexible element 19 lowers the stepped rail 20 embedded in it presses the lever 23 in contact with it and transfers the controller 21 from the third to the second position. An electrical signal is given to decrease the speed of the pump 11. The water level in the tank 2 is stabilized. At the same time, the rail 20 presses the lever 24 in contact with it and includes in the first position the controller 22, which electrically sends a signal to turn on the low speed of the pump 12. The latter takes the water behind the ship 1 by the nozzle 29 and pumps it with a pressure of 30 intake 7 through the water supply nozzle 21 perpendicular to the longitudinal axis of the cone 7 or flow,

passing through pipeline 8 as a result of lowering the water level in the tank 2.

With continued lowering of the water level in the tank 2 in the same way

the step rail 20 and the lever 23 of the controller 21 are transferred from the second to the first position or the pump 11 is completely turned off, the water is stopped from the tank 2, while

the lever 24 of the controller 22 includes position three, giving full revs to the engine of the pump 12. Thus, in the intake cone 7, the pressure jet increases, also increases

the flow of water into the pipeline 8. The pressure of the pressure in the pipeline 8 depends on the volume of the tank 2, the power of the pump 11 and the decrease in the level of water in the tank 2. With increasing
