Abstract

A portable subwater net washing device for breeding net cage, includes a control rod and a cleaning sweep, and a net washing case therebetween. A water mill type impeller is arranged in the net washing case, and the water mill type impeller is connected with the cleaning sweep by a transmission shaft, while the water mill type impeller and the transmission shaft together constitute the actuating unit of the net washing device. The net washing case is provided with a net washing cover thereon, and the net washing case and the net washing cover are respectively provided with a water inlet and water outlet. The invention has simple structure, easy assembly, safe usage, and greatly alleviates the intensity of labor and advances the cleaning efficiency.

Description

Technical field [0001] The invention relates to a net washing device for aquaculture cages, in particular to a portable underwater net washing device. Background technique [0002] In recent years, due to the destruction of the marine ecological environment and the pollution of the cage culture itself, the cages are easily attached by some fouling organisms, which not only shortens the life of the nets, but also brings great negative impacts on management and cultivation . On the one hand, the amount of water exchange between the inside and outside of the box is reduced, and the breeding environment is deteriorated, which affects the growth rate and survival rate of the cultured fish, and is easy to induce diseases; The drift of the clothes under the action of the sea current causes a significant reduction in the breeding volume, and at the same time, the friction between the net clothes will also cause mechanical damage to the breeding objects. Therefore, any fouling orga...
