Method and device for automatically cleaning square frame style net cage by tidal wave underwater

Abstract

A method for automatically cleaning a net cage under tidal waves and water and a square-frame type device thereof relate to the agriculture, that is, the floating type net cage culture at sea. A square frame made of a material which has basically the same dimension as the net cage and small specific is added in a floating square culturing net cage, and assembled with a long strip brush to form a part, namely a square frame type tidal wave brush, and a frame type sinker is connected beneath the square frame type culturing net cage through a connecting rope to form a device. The device can switch between gravity and buoyancy according to tidal changes and wave fluctuation, so as to conduct the upward and downward movement for the net cage, thus cleaning the netting. The invention has the advantages of energy consumption, emission reduction, labor saving, and environmental protection.

Description

technical field [0001] The invention relates to a method and a device for automatically cleaning the net cages underwater at any time in agriculture and sea floating net cage culture. technical background [0002] At present, when the net cage is cultured in the sea, if the net cage is placed in seawater for a long time, some marine organisms will attach to the net clothing, thereby increasing the weight of the net cage, affecting the water exchange inside and outside the net cage, and some animals will compete with the cultured animals. Bait captures oxygen. At present, the method of removing this attachment is mainly to manually replace the net clothes, and remove the attachments through sun exposure and beating. This manual cleaning is carried out on the shore, which will cause certain pollution to the coast. It consumes diesel and emits carbon dioxide. In recent years, some cleaning methods of manual operation machines directly clean the net cages underwater. These met...

[0002] At present, when the net cage is cultured in the sea, if the net cage is placed in seawater for a long time, some marine organisms will attach to the net clothing, thereby increasing the weight of the net cage, affecting the water exchange inside and outside the net cage, and some animals will compete with the cultured animals. bait oxygen

At present, the method of removing this attachment is mainly to manually replace the net clothes, and remove the attachments through sun exposure and beating. This manual cleaning is carried out on the shore, which will cause certain pollution to the coast. consumes diesel and emits carbon dioxide

In recent years, there are some manual cleaning methods for cleaning the net cages underwater. These methods all rely on power sources, diesel engines consume fuel, motors consume electricity, and divers must operate underwater.

[0003] The above-mentioned methods all have labor-intensive, energy-consuming and pollution problems
