Automatic cleaning device for deep sea culture cages

Abstract

The invention discloses an automatic cleaning device for deep sea culture cages. The automatic cleaning device comprises a base, guide wheels, a steel cable and a cleaning plate; the base is placed above a cage base body, a driving wheel is installed below the base, and the driving wheel is driven by a driving motor; an inverse U-shaped guide wheel support frame is fixed inside the base, a pulley is installed inside the guide wheel support frame, and the pulley presses on a handrail; two pairs of guide wheels are fixed at the upper corners of the guide wheel support frame, and the steel cable is connected with the cleaning plate in a suspending mode via the guide wheels. The device is high in automation degree and low in cost, and can be used for cleaning cages in the culture process without taking the cages out of the water for treating, so that the operating link is reduced and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of marine aquaculture equipment, in particular to an automatic cleaning device for deep-sea aquaculture net cages. 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 area is far away from the land, there is a shortage of power energy, the degree of danger of manual work is high, and the labor cost is high. The requirements for automation of deep sea water farming equipment are higher. [0003] The cleaning of deep-sea cages includes the cleaning of buoys and nets. During the breeding process, seawater often has organisms such as barnacles, mussels, and large algae attached to the frame pipe walls and nets of the cages. These attachments not only Cause the life-span of net cage to shorten, and bring great nega...

Problems solved by technology

The deep sea area is far away from the land, the power energy is in short supply, the manual operation is highly dangerous, and the labor cost is high. The deep sea area breeding equipment has higher requirements for automation.

[0003] The cleaning of deep-sea cages includes the cleaning of buoys and nets. During the breeding process, seawater often has organisms such as barnacles, mussels, and large algae attached to the frame wall and nets of the cages. These attachments not only It will shorten the lifespan of cages and bring great negative effects to breeding and management.

The net cage is attached by organisms, which reduces the water exchange between the inside and the outside of the box, the aquaculture environment deteriorates, the nutrient of the water body is intensified, and the oxygen content is reduced, which affects the growth rate and survival rate of the cultured fish, and also increases the net. Clothing resistance, exacerbating the drift of nets under the action of ocean currents, resulting in a significant reduction in the breeding volume, and the friction between the nets will also cause damage to the breeding objects

The existing deep-sea net cages are mainly cleaned manually, but the cost of artificial diving cleaning is high, the time is long, and the safety factor is low; manual net replacement not only increases the cost, but also easily causes a certain degree of scratches on the underwater fish body, affecting the quality of the fish. healthy growth of
