In-roller guide vane push type fish capture set device

Abstract

The invention discloses an in-roller guide vane push type fish capture set device. A rotary base and a clamping seat are installed on a hull; the lower end of an n-shaped base frame is fixed to the rotary base, a hanger is mounted at the top end of the n-shaped base frame, and a fixed pulley is mounted at the top end of the hanger; the left end of the roller is restrained by a roller power hoop, and the roller power hoop is mounted in the middle of the n-shaped base frame through rotating shafts; the right end of the roller is restrained by a roller driven hoop, and a positioning floater is fixed under the roller driven hoop and placed on the clamping seat; a hoist motor is fixed over the n-shaped base frame, a steel cable is driven by the hoist motor and passes the fixed pulley, and the tail end of the steel cable is connected with the roller driven hoop. The device is simple in structure, low in cost, high in fish capture efficiency, low in driving power and low in fish breakage.

Description

technical field [0001] The invention relates to the field of deep-sea aquaculture equipment, in particular to a complete set of device for harvesting fish by pushing the guide vanes in the drum. Background technique [0002] my country has a large demand for aquatic products. As freshwater aquaculture and offshore aquaculture areas become increasingly saturated, the demand for developing deep-sea aquaculture is becoming increasingly strong. The deep sea is far away from the land, there is a shortage of power energy, the risk of manual work is high, and the labor cost is high. Therefore, the deep sea farming equipment has higher requirements for automation. [0003] In the process of cage culture in deep sea areas, the harvesting method is different from that in freshwater fish ponds after the fish are matured. After the nets are harvested, personnel cannot stand and work in the water. The fish harvesting boat is relatively large, and the workload of fish harvesting and handl...

AI Technical Summary

Problems solved by technology

The deep sea area is far away from the land, there is a shortage of power energy, the risk of manual work is high, and the labor cost is high. Therefore, the deep sea aquaculture equipment has higher requirements for automation.

[0003] In the process of cage culture in deep sea areas, the fish harvesting method is different from that in freshwater fish ponds after the fish are matured. After harvesting the nets, personnel cannot stand and work in the water. The fish harvesting boat is relatively large, and the workload of fish harvesting and handling is heavy.

The current simple lifting fish collection device is low in efficiency, and the large fish suction pump consumes a lot of power, which is not suitable for small and medium fishing boats.
