Tide wave and stream wave type ,esh-cage underwater automatic cleaning method and device

Abstract

The invention discloses a submersed automatic cleaning method of a mesh cage of a tidal wave type and a vagrant type, and a device, relating to the agricultural sea floating raft mesh cage breeding, which is the automatic cleaning to the mesh cage. The tidal wave type: an annular hollow float is rearranged on the mesh cage, the float is assembled with a strip bush to form a component, namely, an annular hollow float mesh brush, the lower part of the mesh cage is matched with a hanging object, the part can move up and down by virtue of the change of tide and the floating up and down of sea weave; the vagrant type: the hollow part of the component is filled with water and the proportion thereof is slightly less than 1, the component is then sheathed on the mesh cage. When flowing, the component flows freely to the top of the mesh cage. With the continually changing of the tide towards big, the included angle between the axis line of the mesh cage and sea level changes into a certain small angle, the component moves to the bottom of the mesh cage along the axis direction under the effect of the tide. When the sea wave lifts up the mesh cage, the movement velocity is faster than the component, a relative movement occurs between the two. The two types can achieve the cleaning of the mesh cage. The method has the beneficial effects of saving energy, reducing exhaust, saving labor and protecting environment.

Description

technical field [0001] The invention relates to a method and a device for automatically cleaning the net cage under water at any time in agriculture and sea floating raft net cage culture. technical background [0002] At present, floating raft net cages are cultured in the sea. After the cultured animals are stocked in the cage for a period of time, some animals in the offshore will settle down on the walls of the culture cages and become pollutants. These pollutants occupy a certain space on the walls of the cages. There, they move for feeding, breathing and excreting, compete with the cultured animals for bait, and block the cage, making the current slow or blocked, resulting in the death of the cultured animals due to lack of bait. Therefore, these pollutants must be removed regularly. Inverting the cage is currently the best way to thoroughly clean the cage. [0003] However, this method of regularly removing pollutants is actually carried out when the pollutants have ...

Problems solved by technology

[0006] The multiple round-trip operations of ships not only increases labor costs, but also consumes a large amount of diesel oil and emits a large amount of carbon dioxide. During the whole process of cleaning on the shore, a large number of rotten attachments will bring new pollution to the sea area.
