Description

Technical Field

[0001] The present invention belongs to the technical field of offshore ranches, and in particular to a fixed fusion platform and a use method thereof. Background Art

[0002] With the growth of global population and economic development, human beings are increasingly dependent on marine resources, and the demand for various marine resources is showing a trend of continuous growth. Especially in the field of fisheries, due to the continuous increase in fishing intensity, the marine ecological environment is facing unprecedented pressure, resulting in the continuous expansion of marine pollution and the decline of marine fishery resources. In order to improve the marine ecosystem and alleviate the pressure on fishery resources, the sea ranch is proposed, that is, in a specific sea area, in order to plan and scientifically manage fishery resources, so as to set up artificial fisheries; The traditional marine fishery farming forms in my country include wooden raft cages, rubber raft cages, and some existing large-scale offshore ranch farming platforms. These relatively widespread offshore farming equipment can provide farmers with certain offshore farming conditions. Relying on a complete set of systematic fishery facilities and management systems, various marine organisms are gathered together, allowing farmers to breed better quality fish. This has restored the ecological environment of the ocean to a large extent, provided a more comfortable environment for marine fishery farming, and also solved the problem of marine desertification indirectly caused by overfishing.

[0003] However, when using traditional rafts and rubber-lined cages for aquaculture at sea, farmers often need to take a boat to the sea to feed the fish. Since the aquaculture space of the rafts and rubber-lined cages is small, they cannot provide the workers with sufficient air for rest. In addition, after being soaked in seawater for a long time, the structural strength of the rafts and rubber-lined cages will be reduced. If the waves are large during the process of feeding, the rafts and rubber-lined cages will be easily damaged, resulting in the loss of fish in the rafts and rubber-lined cages, causing serious losses to the marine ranch. Therefore, the operation and maintenance personnel are required to check the rafts and rubber-lined cages every day, and repair the damaged rafts and rubber-lined cages in time, which leads to high work intensity for the operation and maintenance personnel, and thus the economic benefits of using rafts and rubber-lined cages in existing marine ranches are low. Summary of the invention

[0004] In order to solve the problem that traditional rafts and rubber-lined cages are used for aquaculture in existing offshore ranches, which are easily damaged by waves, resulting in serious losses to the ranch, and the operation and maintenance personnel need to inspect the rafts and rubber-lined cages every day, resulting in high workload for the operation and maintenance personnel and low economic benefits of the offshore ranch, the present invention provides a fixed fusion platform and a method for using the same.
