A complete set of fish collection device for pushing type of guide vane in drum

Abstract

The invention discloses a complete set of fish collecting device with guide vanes in the drum. A rotating base and a clamping seat are installed on the hull; the lower end of the inverted U-shaped base frame is fixed on the rotating base, and the top of the inverted U-shaped base frame is installed There is a hanger, and a fixed pulley is installed on the top of the hanger; the left end of the drum is constrained by the drum power clamp, and the drum power clamp is installed in the middle of the inverted U-shaped base frame through the rotating shaft; the right end of the drum is constrained by the drum driven clamp, A positioning float is fixed under the driven clamp of the drum, and the positioning float is placed on the deck; the hoisting motor is fixed above the inverted U-shaped base frame, and the steel cable is driven by the hoisting motor and passes through the fixed pulley. The roller driven clamp is connected. The device of the invention has the advantages of simple structure, low cost, high fish collecting efficiency, low driving power and low fish loss rate.

Description

technical field [0001] The invention relates to the field of deep-sea aquaculture equipment, in particular to a complete set of device for collecting fish with guide vanes in a drum. Background technique [0002] my country has a large demand for aquatic products. With the increasing saturation of freshwater aquaculture and offshore aquaculture areas, the demand for developing deep sea aquaculture is increasingly strong. The deep sea is far from the land, there is a shortage of power and energy, the manual operation is highly dangerous, and the labor cost is high. Therefore, the deep sea aquaculture equipment has higher requirements on the degree of automation. [0003] In the process of deep sea cage culture, the harvesting method of fish harvesting is different from that of freshwater fish ponds. After the net is harvested, the personnel cannot stand in the water, the fish harvesting vessel is large, and the fish harvesting workload is heavy. The currently used simple lif...

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.
