[0031] Deep-sea aquaculture vessels are special vessels that carry out aquaculture operations in open waters far from the coast. This type of vessel integrates modern marine engineering technology and biotechnology, and can operate stably in relatively harsh marine environments to achieve efficient and environmentally friendly aquaculture.

[0032] At present, deep-sea aquaculture vessels can be divided into closed aquaculture vessels and open aquaculture vessels. The main difference lies in whether the aquaculture cabin is directly connected to the seawater and can be replaced by natural water exchange without the need for a circulating water system. Closed aquaculture vessels require a circulating water system to be turned on all day, which has a high aquaculture cost; while the middle of the hull of an open aquaculture vessel is hollowed out and a permeable net is used to enclose a cage structure for aquaculture. This structure is convenient for aquaculture in the sea, but it will encounter greater resistance during navigation, resulting in a slower speed.

[0033] See also Figures 1 to 3The present invention proposes a breeding ship 100 with an openable hull, comprising a hull 1, a permeable net and a sealing assembly 2. The hull 1 is formed with a receiving chamber 11, and openings 12 communicating with the receiving chamber 11 are formed on both sides of the hull 1. There are multiple permeable nets, and the multiple permeable nets divide the receiving chamber 11 into multiple breeding areas 111. The sealing assembly 2 is rotatably installed on the hull 1 to open or seal the opening 12. Specifically, a receiving chamber 11 is opened in the middle of the hull 1, and then the receiving chamber 11 is divided into multiple breeding areas 111 by multiple permeable nets. In order to ensure the fixation of the permeable nets, multiple columns and multiple beams are arranged in the receiving chamber 11, and the multiple beams are connected to the multiple columns. Then the permeable net is installed on the columns and the beams to fix the permeable net. In this way, the permeable net can be better fixed, thereby separating multiple breeding areas 111 and ensuring the strength of the hull 1. An opening communicating with the receiving chamber 11 is also opened on the hull 1. The opening 12 is then rotated and installed on the hull 1; in the navigation mode, the sealing component 2 can be rotated to fit with the opening 12 to seal the opening 12, that is, a continuous and complete hull 1 structure is formed, thereby improving the integrity of the hull 1 shape, reducing the resistance of the aquaculture vessel 100 with an openable hull during navigation, and preventing excessive resistance from affecting the navigation speed of the aquaculture vessel 100 with an openable hull; in the positioning aquaculture mode, the sealing component 2 rotates in the opposite direction, so that the opening 12 can be opened to allow seawater to flow in, and the sealing component 2 can be adjusted according to the positioning aquaculture mode. According to the angle of the incoming flow, the sealing component 2 is rotated and fine-tuned so that it is parallel to the incoming flow direction, so as to realize the maximum natural exchange between the aquaculture water body and the seawater, ensure a high water exchange efficiency and excellent water quality, and ensure the effect of aquaculture. Furthermore, if the incoming flow speed is too fast, the angle of the sealing component 2 can be fine-tuned to fix it in a direction with a certain angle with the incoming flow, so as to reduce the incoming flow speed and avoid a strong impact on the fish school. In the present invention, the accommodating chamber 11 is divided into a plurality of aquaculture areas 111 by setting a permeable net, so that different types of fish can be cultured respectively, and then the opening 12 is set to enable the seawater and the plurality of aquaculture areas 111 to be frequently exchanged with each other in the aquaculture mode, so as to ensure the effect of aquaculture, and the water is automatically exchanged by seawater, and there is no need to increase the internal water circulation system, so as to reduce the cost of aquaculture; and when the aquaculture workboat 100 with an openable and closable hull is sailing, the opening 12 is sealed by driving the rotation of the sealing component 2, i.e., a continuous and complete hull 1 structure is formed, thereby improving the integrity of the hull 1 shape, so that the resistance of navigation can be reduced and the navigation speed of the aquaculture workboat 100 with an openable and closable hull can be improved.

[0034] Furthermore, the hull 1 includes a main frame, which includes multiple columns and multiple beams. The multiple columns and multiple beams are connected in sequence to form a accommodating cavity 11, and then the permeable net is installed on the columns and the beams to fix the permeable net, thereby dividing the entire accommodating cavity 11 into several breeding areas 111. This arrangement can improve the strength of the entire hull 1.

[0035] See also Figures 1 to 4 In one embodiment, the sealing assembly 2 includes a plurality of sealing components 21, and the plurality of sealing components 21 are closely arranged in sequence along the length direction of the aquaculture vessel 100 with an openable and closable hull. Each sealing component 21 includes a rotating shaft 211 and a vertical plate 212. The hull 1 also includes a top longitudinal box beam and a bottom longitudinal box beam, which are respectively located at the top and bottom of the accommodating cavity 11. Both ends of the rotating shaft 211 are rotatably installed on the top longitudinal box beam and the bottom longitudinal box beam, respectively. The rotating shaft 211 is connected to the middle position of the vertical plate 212, and the vertical plate 212 is placed in the opening 12. Specifically, the structure of the sealing assembly 2 is similar to the form of shutters. The sealing assembly 2 includes a plurality of sealing components 21 that are closely arranged along the length direction of the hull 1. Each sealing component 21 includes a rotating shaft 211 and a vertical plate 212, that is, each vertical plate 212 is closely arranged along the length direction of the hull 1, and each vertical plate 212 is set in the opening, and the two ends of each rotating shaft 211 are respectively rotatably installed on the top wall and the bottom wall of the accommodating cavity 11. When the rotating shaft 211 rotates, it can drive the vertical plate 212 to rotate to realize the opening and sealing of the opening 12. In the navigation mode, the rotating shaft 211 is rotated to make each vertical plate 212 rotate to be parallel to the outer surface of the hull 1, that is, multiple vertical plates 212 are closely arranged to cover the opening 12, thereby forming a continuous and complete outer shell structure of the hull 1, improving the integrity of the appearance of the hull 1, and reducing the possibility of the hull 1 being moved during navigation. The resistance encountered by the opening and closing aquaculture boat 100 is improved, and the sailing speed of the aquaculture boat 100 with an openable and closable hull is improved; in the positioning aquaculture mode, each rotating shaft 211 is rotated in the opposite direction, so that each vertical plate 212 can be rotated and fine-tuned according to the angle of the incoming flow, so that each vertical plate 212 is parallel to the incoming flow direction, and the maximum natural exchange between the aquaculture water body and the seawater is achieved, and a high water exchange efficiency and excellent water quality are guaranteed. In this way, there is no need to set up a water circulation system, which reduces the cost of aquaculture. Furthermore, each vertical plate 212 can be adjusted individually, so that the angle of each vertical plate 212 can be adjusted according to the current operating conditions to achieve the best effect; if the incoming flow speed is too fast, the angle of each vertical plate 212 can be fine-tuned to fix it in a direction with a certain angle with the incoming flow, thereby reducing the incoming flow speed and avoiding a strong impact on the fish school.

[0036] See also Figures 1 to 3In one embodiment, the number of openings 12 is multiple, the number of sealing components 2 is multiple, the number of multiple openings 12 and the number of multiple sealing components 2 are equal, and they are arranged one by one. Specifically, multiple openings 12 are arranged, so that the area for water exchange between seawater and aquaculture area 111 can be increased, thereby further improving the efficiency of water exchange between seawater and aquaculture area 111, and further improving the effect of aquaculture; a sealing component 2 is arranged at each opening 12, so that when the aquaculture work boat 100 with an openable hull is in a sailing state, each sealing component 2 will seal the corresponding opening 12, so that it can be ensured that after improving the water exchange efficiency, the speed of the aquaculture work boat 100 with an openable hull will not be reduced.

[0037] See also Figures 1 to 4 In one embodiment, the aquaculture vessel 100 with an openable and closable hull further includes an operating link 3, the number of the operating link 3 is multiple, the number of the multiple operating links 3 is equal to the number of the multiple sealing assemblies 2, and one operating link 3 is connected to multiple rotating shafts 211 in a sealing assembly 2. Specifically, the structure of the sealing assembly 2 is similar to the shutter form. The sealing assembly 2 includes a plurality of sealing components 21 that are closely arranged along the length direction of the hull 1. Each sealing component 21 includes a rotating shaft 211 and a vertical plate 212, that is, each vertical plate 212 is closely arranged along the length direction of the hull 1, and each vertical plate 212 is arranged in the opening, and the two ends of each rotating shaft 211 are respectively rotatably installed on the top wall and the bottom wall of the accommodating cavity 11. When the rotating shaft 211 rotates, it can drive the vertical plate 212 to rotate to realize the opening and sealing of the opening 12. In the navigation mode, the plurality of rotating shafts 211 are rotated at the same time by operating the connecting rod 3, so that each vertical plate 212 will rotate at the same time to be parallel to the outer surface of the hull 1, that is, the plurality of vertical plates 212 are closely arranged to cover the opening 12, thereby forming a continuous and complete outer surface of the hull 1. The shell structure improves the integrity of the hull 1, reduces the resistance of the aquaculture vessel 100 with an openable hull during navigation, and improves the operating speed of the aquaculture vessel 100 with an openable hull; in the positioning aquaculture mode, the multiple rotating shafts 211 are simultaneously rotated in the opposite direction by moving the operating connecting rod in the reverse direction, so that each vertical plate 212 can be rotated and fine-tuned at the same time according to the angle of the incoming flow, so that each vertical plate 212 is parallel to the incoming flow direction, thereby realizing the maximum natural exchange between the aquaculture water body and the seawater, ensuring a high water exchange efficiency and excellent water quality, so that there is no need to set up a water circulation system, reducing the cost of aquaculture, and by setting the operating connecting rod 3, multiple sealing components 21 can be operated simultaneously, and all sealing components 21 can be opened and closed synchronously, which greatly reduces the operating difficulty of the operator and improves the operating efficiency.

[0038] In one embodiment, the aquaculture vessel 100 with an openable hull further includes a linear drive mechanism, the extension shaft of which is connected to the operating link 3 , and the extension shaft of the linear drive mechanism can be extended or retracted to allow the vertical plate 212 to open or seal the opening 12 . Specifically, the structure of the sealing assembly 2 is similar to that of a shutter. The sealing assembly 2 includes a plurality of sealing components 21 that are closely arranged along the length direction of the hull 1. Each sealing component 21 includes a rotating shaft 211 and a vertical plate 212, that is, each vertical plate 212 is closely arranged along the length direction of the hull 1, and each vertical plate 212 is arranged in the opening. The two ends of each rotating shaft 211 are respectively rotatably installed on the top wall and the bottom wall of the accommodating chamber 11. When the rotating shaft 211 rotates, it can drive the vertical plate 212 to rotate to realize the opening and sealing of the opening 12. In the navigation mode, the linear drive mechanism is started, so that the extending shaft of the linear drive mechanism will retract, driving the plurality of rotating shafts 211 to rotate at the same time, so that each vertical plate 212 will simultaneously rotate to be parallel to the outer surface of the hull 1, that is, the plurality of vertical plates 212 are closely arranged to cover the opening 12, thereby forming a continuous and complete The outer shell structure of the hull 1 improves the integrity of the shape of the hull 1, reduces the resistance of the aquaculture ship 100 with an openable hull during navigation, and improves the operating speed of the aquaculture ship 100 with an openable hull; in the positioning aquaculture mode, the linear drive mechanism is started again, and the extension shaft of the linear drive mechanism will be extended, which will cause the multiple rotating shafts 211 to rotate in the opposite direction, so that each vertical plate 212 can be rotated and fine-tuned at the same time according to the angle of the incoming flow, so that each vertical plate 212 is parallel to the incoming flow direction, realizing the maximum natural exchange between the aquaculture water body and seawater, ensuring a high water exchange efficiency and good water quality, so that there is no need to set up a water circulation system, reducing the cost of aquaculture, and by setting up the linear drive mechanism, there is no need for operators to manually seal or open the opening 12, further reducing the operating difficulty of the operators and further improving the operating efficiency.

[0039] See also Figures 1 to 3In one embodiment, the hull 1 includes a bow 13 and a stern 14, and both the bow 13 and the stern 14 are streamlined structures. The hull 1 includes a bow 13 and a stern 14, and both the bow 13 and the stern 14 are streamlined structures, which is a highly optimized design aimed at improving the navigation performance of the ship, reducing resistance, improving fuel efficiency and enhancing stability. The streamlined design can significantly reduce the shape resistance caused by the shape of the hull 1, allowing the water flow to bypass the hull 1 more smoothly and reduce energy loss. The smooth surface reduces the friction resistance between the water flow and the surface of the hull 1, further improving the navigation efficiency. The streamlined design of the bow 13 and the stern 14 allows the water flow to flow more smoothly around the hull 1, reducing the generation of turbulence and eddies, thereby increasing the speed. Reducing resistance means that the engine needs to consume less energy to propel the ship, improving fuel efficiency. The streamlined design helps to maintain the longitudinal stability of the ship, reduce shaking and bumping, and improve ride comfort and safety. The optimized streamlined design can also improve the lateral stability of the ship and reduce rolling and heeling. The streamlined design reduces the turbulence of the water flow, thereby reducing the noise and vibration caused by the turbulence and improving the comfort of the passengers. The streamlined design makes the appearance of the hull 1 more neat and beautiful, and improves the overall visual effect of the ship. The streamlined bow 13 can reduce the direct impact of waves on the hull 1, protect the hull 1 and the internal equipment. The streamlined design of the bow 13 helps to smoothly guide the water flow to the middle of the hull 1, reduce turbulence, and improve navigation efficiency. The bow 13 adopts a smooth surface design to reduce the friction resistance between the water flow and the surface of the hull 1. The cross-section of the bow 13 gradually tapers to form a gradual streamlined profile, which helps to reduce the separation of water flow and the generation of vortices. The streamlined stern 14 design ensures that the water flow discharged from the propeller is smoother, reduces turbulence, and improves the efficiency of the propulsion system. The water flow is evenly distributed at the stern 14, avoiding local energy waste and further improving the propulsion efficiency. The streamlined design helps to reduce the tail vortex generated by the stern 14 and further reduce resistance. The connection area between the stern 14 and the hull 15 adopts a smooth transition design to ensure that the water flows out of the stern 14 more smoothly and reduces turbulence. The streamlined design of the bow 13 and the stern 14 work together to significantly improve the overall navigation efficiency of the ship. Reducing resistance and improving propulsion efficiency make the ship more energy-efficient and reduce operating costs. This design enables the ship to maintain good performance in different sea conditions and adapt to various navigation tasks.

[0040] See also Figures 1 to 3In one embodiment, the outer shell of the bow 13 adopts a fully welded structure. Specifically, the outer shell of the bow 13 is completely connected by steel plates through welding technology to form a complete and continuous structure; such a fully welded structure makes the bow 13 a whole, which improves the rigidity and strength of the entire bow 13. When encountering big waves or collisions, the complete welded structure can better disperse and absorb the impact force and protect the safety of equipment and personnel inside the hull 1. Welding connection has better sealing than riveting or other connection methods, which can effectively prevent seawater from penetrating into the hull 1 and improve the safety and reliability of the ship. The welded joints are treated to reduce the risk of corrosion and extend the service life of the hull 1. The complete welded structure makes the surface of the bow 13 smoother, reduces the direct impact of the water flow on the hull 1, and reduces the generation of turbulence and eddies. The smooth surface helps to achieve a streamlined design, reduce navigation resistance, and improve speed and fuel efficiency. The welded structure makes the appearance of the bow 13 more neat and beautiful, and improves the overall visual effect of the ship. Modern welding technology can efficiently complete the assembly of large hulls 1 and improve manufacturing efficiency. If maintenance is required, the welded structure can be repaired or replaced locally to solve the problem, which is relatively convenient.

[0041] See also Figures 1 to 3 In one embodiment, the hull 1 further comprises a hull 15, the bow 13 and the stern 14 are respectively connected to the two sides of the hull 15, and the connection area between the stern 14 and the hull 15 is smoothly transitioned. The smooth transition between the stern 14 and the hull 15 is to ensure that the water flow can flow smoothly through the hull 1, thereby reducing resistance and improving navigation efficiency.

[0042] See also Figure 1 In one embodiment, a plurality of fishing ports 151 are formed on the top of the hull 15 and are interconnected with the accommodating chamber 11. The number of the plurality of fishing ports 151 is equal to the number of the plurality of breeding areas 111, and they are arranged in a one-to-one correspondence. By arranging the fishing ports 151 on the top of the hull 15, the operator can catch the farmed fish through the fishing ports 151, so that there is no need to work underwater, and the plurality of breeding areas 111 correspond to a fishing port 151 respectively, and the operator can catch different fishes according to different fishing ports 151.

[0043] In one embodiment, the aquaculture vessel 100 with an openable hull further includes two bow thrusters and two fully rotating rudder propellers. The two bow thrusters are respectively arranged on both sides of the bow 13, and the two fully rotating rudder propellers are arranged at intervals at the stern 14 along the width direction of the aquaculture vessel 100 with an openable hull. The bow thruster is a small propeller installed on both sides of the bow 13, which is mainly used to help the ship to move laterally in narrow waters or when berthing. The bow thruster can be a channel spiral thruster or a water jet thruster. The bow thruster can generate lateral force to make the hull 1 easier to control. The two bow thrusters are respectively arranged on both sides of the bow 13, which can more effectively balance the lateral force and improve the operational flexibility of the ship in a small space. The fully rotating rudder propeller is a propeller that can rotate in all directions, usually installed at the stern 14. This device combines the functions of a traditional propeller and a rudder, can generate thrust in any direction, and greatly improves the maneuverability and controllability of the ship. Two fully rotating rudder propellers are arranged at intervals at the stern 14 along the width direction of the aquaculture vessel 100 with an openable hull. Such a layout can better distribute the thrust and ensure the stability and maneuverability of the vessel in all directions. This configuration is very important for maintaining the position and direction of the vessel, especially in a complex marine environment.
