A large-scale aquaculture fishing net suitable for harsh sea conditions with the function of anti-wave and current-blocking power generation

Abstract

The invention discloses a large-scale aquaculture fishing net suitable for harsh sea conditions and having the function of preventing waves and currents to generate electricity. For aquaculture, the outer net cage is used for wave and flow resistance and water quality exchange. The outer net cage is divided into three layers as a whole. The first layer is used to install the anti-wave and wave-dissipating power generation module. Hydraulic power generation device; the second layer is a flow reduction layer composed of several floating balls; the third layer is a water quality exchange layer. In the present invention, the traditional sea culture net cage is improved to solve the problem that the traditional net cage and the anchor rope are easily damaged under harsh sea conditions, greatly prolong the service life of the culture net cage, and improve the ability of the net cage to be lower than the harsh sea condition. It not only has the function of preventing waves and blocking currents, but also uses the kinetic energy of waves and ocean currents to generate electricity, transforming harmful energy into beneficial electric energy, and realizing the concept of green and environmental protection design.

Description

technical field [0001] The invention belongs to marine engineering technology, and in particular relates to a large-scale farming fishing net suitable for harsh sea conditions and having the function of preventing waves and blocking currents to generate electricity. Background technique [0002] With the improvement of people's living standards, people's demand for seafood is increasing. According to the population growth rate and per capita demand, it is estimated that by 2030, there will be at least more than 40 million tons of seafood demand. However, due to people's overfishing, the total amount of fish stocks has dropped sharply. In order to meet people's demand for aquatic products, vigorously developing sea seine aquaculture has become the mainstream, and the scope of seine aquaculture is increasing year by year. Our country has a vast sea area and rich marine resources. There is a lot of room for the development and utilization of marine resources. The rich fish reso...

Problems solved by technology

[0003] Marine cage culture has the characteristics of low investment, high output, maneuverability, and quick results. However, traditional culture cages can only be placed in shallow seas and inner bays, and have poor wind and wave resistance. The fracture will destroy the overall structure of the cage and cause a large number of fish to escape. Therefore, the structural design of the breeding cage needs to be studied, and the design of a new type of breeding cage with a wind-resistant structure has become the focus of the research.
