Embodiment Construction

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] Please refer to figure 1 , The present invention provides a deep-sea aquaculture gravity net cage pumping water lifting control method, comprising the following steps:

[0046] Step S1: evenly set 4 buoys on the perimeter side of gravity cage, each buoy is provided with 2 submersible pumps, 1 is to carry out pumping, and 1 is to carry out water injection;

[0047] Step S2: set up the lifting motion equation of cage according to the principle of physics;

[0048] Step S3: based on the lifting motion equation, solve the controller with the analysis method of Lyapunov function stability, for controlling the buoy pumping or water injection, and further controlling the lifting of the gravity cage.

[0049] In this embodiment, the step S2 is specifically:

[0050] Step S21: establish the dynamic equation of the submersible pump:

[0051]

[0052] ...

Abstract

The present invention relates to a method for pumping and injecting water up and down in a gravity-type cage for deep-sea culture, comprising the following steps: step S1: setting a plurality of buoys around the gravity-type cage; step S2: establishing a lifting motion equation of the cage according to physical principles; Step S3: Based on the lifting motion equation, use the analysis method of Lyapunov function stability to solve the controller, which is used to control the pumping or water injection of the buoy, and further control the lifting of the gravity cage. The invention can realize the stable settlement of the deep-sea culture gravity net cage.

Description

technical field [0001] The invention relates to the technical field of deep-sea aquaculture in cages, and relates to a lifting control method for water-pumping and injection in a gravity-type cage for deep-sea aquaculture. Background technique [0002] In recent years, due to the problems of overfishing and environmental pollution worldwide, fishery resources have experienced a serious decline. To this end, the focus of the fishery industry has been shifted from traditional hunting fishery to grazing-style aquaculture fisheries, especially to avoid the pollution-prone environment in the coastal bays, and turn to the open sea to develop deep-water cage aquaculture for fish with high economic value. It has become the consensus of all countries in the world. As an industry, deep-water cages can alleviate the current decline of marine fishery resources; it can also drive related industries such as cage production, seedling cultivation, bait production, processing and preservati...
