Description

Technical Field

[0001] The invention relates to the technical field of aquaculture vessels, and in particular to a movable three-dimensional layered variable-structure aquaculture vessel. Background Art

[0002] In my country, marine fisheries are the main force of the marine economy. At present, marine aquaculture is mainly carried out in the nearshore area. Due to the slow water flow in the nearshore area, pollutants are not easy to spread, and the water quality is poor, it is difficult to carry out high-quality fish farming. In recent years, the marine ecological problems faced by inner bays, mudflats and other offshore aquaculture waters have become more severe. Unfavorable conditions such as inland pollutant emissions, marine oil leakage, radioactive nuclear materials and self-source pollution of seawater aquaculture have greatly compressed the available space for offshore aquaculture. At present, offshore aquaculture sites are basically saturated. Therefore, it has become an inevitable choice for development to expand the development space of marine fisheries, improve quality, reduce pollution, develop new marine fishery aquaculture technologies and equipment, and move seawater aquaculture from harbors and offshore to deep sea and open waters.

[0003] With the high profit returns of deep-sea fish species, the scale of deep-sea aquaculture has expanded rapidly. The development of deep-sea aquaculture is of great strategic significance to my country's food safety, fishery economy and diversified development of deep-sea resources. At present, there are two deep-sea aquaculture modes: one is the closed-circulation water aquaculture mode; the other is the fully open aquaculture mode. The former requires the installation of a special closed-circulation water treatment system, which has high system construction cost and high operation cost; the latter is to place the aquaculture cages completely in the sea area, use the flow of seawater in the sea area for water exchange, and does not require any water treatment system. It is a fully open aquaculture mode and a traditional aquaculture mode. Deep-sea aquaculture vessels based on aquaculture cages can not only expand the utilization rate of deep-sea marine aquaculture space, but also improve the aquaculture level. At the same time, the use of aquaculture vessels for aquaculture of fishery products is convenient for transportation, thereby ensuring the freshness of fishery products. Deep-sea aquaculture vessels have become an inevitable strategic choice for the development of my country's marine fisheries.

[0004] At present, large-scale aquaculture vessels have been put into use, but when the existing aquaculture vessels are hit by typhoons or extreme winds and waves, the cages will be deformed or even destroyed, and the farmed fish will die or escape, causing serious economic losses. How to improve the survivability of aquaculture vessels so that they can avoid extreme winds and waves is an important issue that needs to be solved urgently. Summary of the invention

[0005] The purpose of the present invention is to provide a movable three-dimensional layered variable structure aquaculture vessel to improve aquaculture output and efficiency, and improve the survivability of the aquaculture vessel when encountering severe weather such as typhoons.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a movable three-dimensional layered variable structure aquaculture work boat, comprising a hull, aquaculture cages and a lifting drive device; the hull comprises a superstructure, a propeller propeller and a deck; the aquaculture cages are composed of three steel cables connected in series with a net; the lifting drive device comprises three winches, the winches are all fixed on the deck of the hull and wind up the steel cables of the aquaculture cages, and the winches comprise an electric motor, a drum, a bracket, a base and a chain.

[0007] The characteristic of the invention is that the superstructure includes a crew living area, a ship's driving room, a fish feed storage room, a live fish quick-freezing cold storage room, a fish processing room, etc.

[0008] The characteristic is that the propeller thruster is arranged at the stern of the ship, which can push the ship away from dangerous waters before the arrival of severe weather such as typhoons, thereby ensuring the safety of aquaculture.

[0009] The invention is characterized in that the breeding cage is arranged at the bottom of the hull, and the net is a water-permeable structure, so as to ensure that sufficient seawater exchange can be carried out everywhere in the breeding space, thereby creating an optimal environment suitable for the growth of farmed fish; the breeding cage is provided with a feeding port for farmed fish feed on the deck, which is convenient for manual feeding or feeding by a feeding device; the breeding cage can be extended underwater to form a three-dimensional structure, expand the breeding space, and enable different types of farmed fish to automatically live in layers at each adaptive water depth, thereby ensuring the demand of farmed fish for dissolved oxygen and improving breeding output and benefits.

[0010] It is characterized in that the lifting drive device can retract the aquaculture cage into the cabin at the bottom of the hull before extreme winds and waves come, which facilitates the movement of the ship without affecting the life of the farmed fish and ensures the survivability of the aquaculture ship; when the sea conditions stabilize, the lifting drive device will lower the aquaculture cage back into the seawater at the bottom of the hull.

[0011] The beneficial effects of the present invention are as follows: 1. Ming's aquaculture cages are permeable nets connected in series with steel cables, which can maintain good water exchange in the aquaculture water inside the aquaculture cages, reduce the number of bacteria and parasites in the aquaculture cages, and ensure that the farmed fish have a good living environment; the aquaculture cages extend underwater to form a three-dimensional structure, which not only expands the aquaculture space but also enables different types of farmed fish to automatically live in different adaptive water depths in layers, ensuring the healthy growth of farmed fish and improving aquaculture production and benefits.

[0012] 2. The aquaculture vessel of the present invention is provided with a propeller propeller at the stern and has a self-propulsion function. When a typhoon strikes or the water temperature changes greatly or the water body is eutrophicated, the vessel can sail away from dangerous or unsuitable sea areas for aquaculture, thereby improving the efficiency and safety of aquaculture.

[0013] 3. Before extreme wind and waves come, the lifting drive device of the present invention can retract the aquaculture cage to the bottom cabin of the hull to facilitate the movement of the hull, thereby improving the survivability of the aquaculture vessel.

[0014] 4. The aquaculture vessel of the present invention is equipped with a crew living area, a ship's cab, a farmed fish feed storage room, a live fish quick-freezing cold storage room, and a fish processing room, etc., which can realize the instant catching and processing of farmed fish, keep the fish fresh through ultra-low temperature quick freezing, and reduce the transportation cost of feed and finished fish while maintaining the quality of fish meat.
