Description

TECHNICAL FIELD

[0001] The present application relates to the field of mariculture devices, in particular to a wind and wave resistant rapid fishing mariculture device and operation method. BACKGROUND

[0002] With the increasing global population and rising demand for seafood, the mariculture industry has rapidly developed and become one of the important ways to meet human protein demand. However, traditional mariculture equipment often shows many shortcomings when facing adverse sea conditions, especially in strong wind and waves. Under adverse weather conditions, mariculture devices are easily damaged by strong winds and waves, leading to damage of mariculture facilities, loss of fishery resources, and even potential ecological pollution.

[0003] Traditional mariculture devices usually rely on fixed structures such as net cages or floating platforms, which have insufficient wind and wave resistance in strong wind and waves, are prone to deformation, damage, or even being overturned or washed away by waves. This not only increases the maintenance cost of the equipment, but also greatly increases the risk of mariculture operations. In addition, the design of existing devices is often complex, making installation and operation difficult, resulting in low fishing efficiency and difficulty in meeting the growing scale of mariculture demand.

[0004] In the current related technology, a Chinese patent with application publication number CN116171904B discloses an umbrella-shaped self-elevating mariculture device, which is composed of a main frame, an upper assembly, a central assembly, and a bottom net cage. The main frame is a large open ring-shaped float, with a circular apron at the edge. The inner side of the circular apron is provided with a sliding rail, and the outer side is provided with a ring-shaped inclined ramp. A water spraying device is installed at the highest point of the ring-shaped inclined ramp. The upper assembly includes an arc-shaped support pipe, a top platform, and a winch. The arc-shaped support pipe is distributed at an angle of 120 degrees and converges at the top center. The top platform is Y-shaped and fixed to the top of the arc-shaped support pipe. The central assembly is fixed to the upper assembly at the upper end and connected to the bottom net cage at the lower end. The bottom net cage has an inverted umbrella shape, and the top of the bottom net cage is connected to the bottom of the main frame. This scheme realizes rapid fishing through the umbrella-shaped structure and the winch at the top, but the center of gravity is too high, making it difficult to resist adverse wind and wave environments.

[0005] Therefore, it is necessary to provide a wind and wave resistant rapid fishing mariculture device and operation method to solve the above problems. SUMMARY

[0006] The purpose of the present application is to provide a wind and wave resistant rapid fishing mariculture device and operation method. Through the form of a whole body tensioned main structure, the wind and wave resistance of the device is improved.
