A ship-mounted electronically controlled fish-water automatic separation device and separation method

Abstract

The invention relates to an onboard electric-control fish-water automatic separation and sorting apparatus and a separation method thereof. The separation apparatus comprises a fish inlet channel, a fish-separating box body, a fish outlet channel, filtering rollers, a drainage channel, balance weight blocks, a support device and an electric control device; the filtering rollers are arranged at thelower part of the inner part of the fish-separating box body and are a plurality of parallel rotatable cylindrical rollers; the support device comprises a box body base, spherical universal joints, spring shock absorbers and a base support frame; the box body base is arranged at the bottom of the fish-separating box body; the lower end of the box body base is provided with the balance weight blocks which are made of heavy metal; the box body base is connected with the base support frame through the spherical universal joints and the spring shock absorbers; and the spherical universal joints are positioned at the upper ends of the spring shock absorbers. The separation apparatus can maintain a certain horizontal state on a swinging fishing boat and can continuously and normally work. In addition, whether fish bodies are accumulated to cause blocking or not can be monitored in real time, and corresponding measures are automatically taken to dredge the accumulated fish bodies. Human intervention is not needed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a ship-mounted electronically controlled fish-water automatic separation and arrangement device and a separation method thereof. Background technique [0002] As an important part of my country's agricultural production, fishery fishing occupies an important position in my country's economic development. At present, most people adopt the mode of fishing with a side-lift net in the process of fish fishing. After the fish enters the net, the fish-water mixture is sucked from the sea to the boat with a fish-suction pump and then separated. [0003] Ordinary fish-water separation equipment can only work normally in a stable environment. For example, the utility model patent of authorized notification number CN202890209 U discloses a fish-water separator for saury boats, which includes an inclined fish separation box. The body's own gravity will discharge the fish body from the inclined box. Fishing boats are usually greatly affe...

Problems solved by technology

However, fishing boats are usually greatly affected by sea conditions, and the swing and vibration of the deck is more serious. Therefore, the tilted fish separation box cannot maintain its tilt angle on a swinging fishing boat, so that it cannot use gravity to separate fish and water. On the contrary, if the deck swings excessively Under normal circumstances, the fish body may return from the fish discharge port to the fish inlet port, resulting in repetitive work and low work efficiency

[0004] In addition, another disadvantage of traditional fish separation equipment is that when the fish feed speed is fast, fish body accumulation is easy to form in the fish separation box, thereby blocking the fish outlet, and it is necessary to manually dredge the accumulated and blocked fish bodies , the labor intensity of the workers is extremely high, and the separated fish bodies are in disorder, which is not easy to form an automated assembly line operation
