Sea net cage farmed fish automatic collecting system

Abstract

The invention discloses a sea net cage farmed fish automatic collecting method. A mobile horn-shaped fish collection device is connected with a soft telescopic seawater pipe, the other end of the seawater pipe is connected with a fish and water separation device, the fish and water separation device is connected with a seawater pump, and the seawater pipe and the fish collection device are suspended on a telescopic suspension rod through a rope. The fish collection device, the seawater pipe, the fish and water separation device, the seawater pump, the telescopic suspension rod and the rope form a sea net cage farmed fish automatic collecting system. In the operation process, the seawater pipe and the fish collection device extend into a farming net cage through the telescopic suspension rod, and the seawater pipe and the fish collection device descend to be at different water depths in the farming net cage by adjusting the rope; the seawater pump is started to pump seawater, fishes and seawater are sucked into the seawater pipe by the fish collection device, fishes and water are separated by the fish and water separation device, seawater is sucked into the seawater pump to be drained through the pipe end, fishes are placed into a fish net bag via a lower opening of the fish and water separation device, and net cage farmed fishes are automatically collected.

Description

technical field [0001] The utility model relates to an automatic harvesting system for aquaculture fish in a marine net cage, which relates to a supporting equipment system for a marine aquaculture fishery vessel, and belongs to the field of marine vessels. Background technique [0002] Most of the current marine cage cultured fish are fished manually by fishermen, relying on fishermen to manually lift the net and manually take the net bag to catch the cultured fish, and the labor intensity of the fishermen is high; and because the current marine cage culture is moving from the shallow sea to the deep sea, From the inner bay to the outer sea, the wind, waves, and currents in the outer sea are fast. If the fishermen still rely on manual lifting of the nets and hand-held nets to catch farmed fish, it will cause problems such as the safety of fishermen's work. [0003] In order to overcome the current marine cage culture fish, rely on fishermen to manually lift the net and manu...
