With the rapid development of social economy, people's demand for high-quality aquatic products is increasing. In recent years, my country's offshore fishery resources have been increasingly depleted, and marine fishing production has decreased year by year. The supply of aquatic products mainly depends on mariculture. Because the marine aquaculture industry is greatly affected by the nearshore hydrological environment, and the nearshore aquaculture system will affect the nearshore water quality conditions due to the accumulation of residual bait, feces and drugs, thereby endangering the quality of aquatic products, thus forming a vicious circle. Therefore, the domestic The aquaculture industry began to set its sights on the deep sea with better water quality and more suitable water temperature, actively explored deep sea culture technology, and realized the integration of "fishing-breeding-processing" of deep-sea fish by relying on large-scale deep-sea farming ships, continuously providing High-quality aquatic products to meet the people's growing demand for aquatic products have become an important development direction of the mariculture industry.

At present, the existing deep-sea farming ships generally have the problem of insufficient resistance to wind and waves. When encountering bad weather, they can only leave the operating sea area by self-propelled or towed to return to the port to avoid, which will greatly reduce the economy of farming ships.

In the above-mentioned deep-sea breeding workboat, the submersible pump 111 provided can inject seawater into the submersible chamber 12, and when encountering extreme weather such as a typhoon, the whole hull can be submerged to a certain depth underwater. The protective function of the body 1 can make the hull withstand the seawater pressure at a certain depth, thereby avoiding extreme bad weather. When the weather improves, inject compressed air into the diving chamber 12 through the air compressor station 2 provided. The water in the lower diving chamber 12 is discharged under the action of pressure, so that the whole body of the boat can be floated, and its conventional breeding state can be restored.
