Description

Technical Field

[0001] This invention relates to deep-sea aquaculture equipment, and more particularly to a deep-sea aquaculture vessel. Background Technology

[0002] Conventional ship designs, considering the impact on longitudinal structural strength and the local strength of the engine room, incorporate numerous bulkheads and stiffening ribs. Based on years of ship design experience and to ensure the continuity of ship strength, the direction of these stiffening ribs is generally kept consistent to prevent local bulkheads from experiencing tensile or compressive stresses significantly exceeding their capacities. If the bulkhead stiffening ribs are arranged solely according to the compartment's function, resulting in a chaotic arrangement, the compartment may develop mid-sag, sag, or significant torque. When a local compartment is weaker in tension than in compression, plastic failure may occur, leading to structural instability and ultimately endangering the ship.

[0003] However, existing technologies often utilize the hull structure for aquaculture. In order to avoid the impact of protruding reinforcing ribs on the fish's life, the reinforcing rib structure is often adjusted, resulting in a chaotic arrangement of the reinforcing ribs and thus the situation described above.

[0004] In addition, existing technologies often use inclined grooves in the aquaculture tank to solve the problem of fish feces and uneaten food adhering to the inner wall of the aquaculture tank. However, this only provides a minor improvement. Most of the feces and uneaten food are in a floating state in the aquaculture tank, so more of them adhere to the tank wall. Under conditions of small inclination, the feces and uneaten food will not slide to the drain outlet as the structure tilts, but will continue to accumulate at the bottom of the tank.

[0005] Furthermore, in existing technologies, the aquaculture tank is welded from steel plates. Steel plates have a large roughness and excellent heat transfer performance. For aquaculture fish that have temperature requirements, the heat exchange is significantly faster, which has obvious drawbacks. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a deep-sea aquaculture vessel.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] A deep-sea aquaculture vessel includes a hull, which includes isolation bulkheads and longitudinal bulkheads. The hull is divided into several rows of aquaculture areas, each of which operates independently. The aquaculture areas in the same row are arranged sequentially from the bow to the stern of the hull. Adjacent aquaculture areas in the same row are separated by the isolation bulkheads. Adjacent aquaculture areas in different rows are separated by the longitudinal bulkheads.

[0009] The deep-sea aquaculture vessel also includes aquaculture tanks for aquaculture operations. Each aquaculture tank corresponds to a specific aquaculture area and is built into the aquaculture area. The aquaculture tanks are configured to float within the aquaculture area.

[0010] In this plan, aquaculture tanks are set up within the aquaculture area for aquaculture operations. These tanks are designed to float in water, so the hull's own reinforcing ribs do not affect the aquaculture operations. Therefore, the hull's reinforcing ribs can be aligned in the same direction according to existing specifications. Furthermore, several aquaculture areas are divided into independent aquaculture zones using the hull's isolation bulkheads and longitudinal bulkheads. These bulkheads serve to both isolate and reinforce the hull's lateral and longitudinal strength, while also maximizing internal space utilization and resulting in a compact hull structure.

[0011] Preferably, the hull has two rows of aquaculture areas, the longitudinal bulkhead extends from the bow to the stern of the hull, and the two sides of the isolation bulkhead are fixedly connected to the hull side and the longitudinal bulkhead, respectively.

[0012] In this design, a longitudinal bulkhead runs through the bow and stern of the hull, ensuring the longitudinal strength of the hull. The longitudinal bulkhead is fixed to each isolation bulkhead and also provides lateral support for the hull.

[0013] Preferably, the two rows of isolation bulkheads are staggered along the longitudinal direction of the hull, which helps to improve the uniformity of the force on the hull.

[0014] Preferably, two rows of isolation bulkheads are spaced apart in the transverse direction of the hull. The longitudinal bulkheads have bending grooves that correspond one-to-one with each of the aquaculture areas. The two ends of the bending grooves are fixedly connected to the isolation bulkheads of the corresponding aquaculture areas, and the middle part of the bending grooves is fixedly connected to the isolation bulkheads of the other row of aquaculture areas.

[0015] In this design, the longitudinal bulkheads are configured as trough-shaped bulkheads as described above, extending from the bow to the stern of the hull to provide lateral support and improve the longitudinal strength of the hull.

[0016] Preferably, the two rows of aquaculture areas are staggered in the longitudinal direction of the hull, and the aquaculture tanks corresponding to two adjacent aquaculture areas in different rows are connected by a fish-driving channel.

[0017] This solution improves the space utilization within the ship's hull and enables the exchange of fish and water between adjacent aquaculture tanks by setting up fish-driving channels. It allows water to be injected into all aquaculture tanks through a single tank and allows different sizes of fish to be raised in different tanks. For example, the fish in the tanks at the bow of the ship are the smallest, while the fish in the tanks closer to the stern are the largest. Fishing is then carried out at the stern, while the fish at the bow are driven step by step towards the stern.

[0018] Preferably, the aquaculture tank is made of a transparent material, which facilitates observation of the fish's growth.

[0019] Preferably, the aquaculture tank is made of glass, which not only facilitates observation but also has a heat preservation effect, reducing the frequency of drawing seawater from the deep sea into the aquaculture tank, thereby reducing the cost of aquaculture. In addition, it also makes it easier to clean the aquaculture tank.

[0020] Preferably, the aquaculture tank includes a cylindrical section and a spherical section, with the upper end of the spherical section fixedly connected to the lower end of the cylindrical section.

[0021] In this design, the lower part of the aquaculture tank is made into a spherical shape to avoid the adhesion of feces and uneaten feed, thus helping to ensure the water quality inside the aquaculture tank.

[0022] Preferably, the deep-sea aquaculture vessel further includes a water injection system connected to the upper part of the aquaculture tank, the water injection system being used to draw deep-sea water and inject it into the aquaculture tank;

[0023] Preferably, the deep-sea aquaculture vessel also includes a sewage system connected to the bottom of the aquaculture tank, the sewage system being used to drain water from the aquaculture tank;

[0024] Preferably, the aquaculture area includes a floating space located outside the aquaculture tank, and the deep-sea aquaculture vessel also includes a buoyancy control system. The buoyancy control system is used to regulate the water level in the floating space. The aquaculture tank is configured to sink and trigger a sewage discharge switch as the water level in the floating space decreases, and is configured to detach from the bottom of the hull and float in the aquaculture area as the water level in the floating space rises.

[0025] Preferably, the deep-sea aquaculture vessel also includes an observation cabin, the isolation bulkhead being a double-layered hollow structure, and the observation cabin being formed inside. The isolation bulkhead has observation windows made of transparent material, allowing people inside the observation cabin to observe the situation inside the transparent aquaculture tank.

[0026] Preferably, the deep-sea aquaculture vessel also includes an observation platform, which is located between the aquaculture tank and the isolation bulkhead.

[0027] Preferably, the hull further includes two transverse bulkheads, which are located at the bow and stern of the hull respectively, and each of the aquaculture areas is located between the two transverse bulkheads.

[0028] Preferably, the aquaculture area is formed between the transverse bulkhead and an isolation bulkhead at the edge, or the aquaculture area is formed by the transverse bulkhead and multiple isolation bulkheads in different rows at the edge.

[0029] Preferably, the hull further includes an outer shell and an inner shell spaced apart, the inner shell being built inside the outer shell and fixedly connected to the outer shell, and the isolation bulkhead being fixed to the inner shell;

[0030] Preferably, the hull further includes a deck, the aquaculture area is located below the deck, and the upper end of the longitudinal bulkhead is fixedly connected to the deck.

[0031] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0032] The positive and progressive effects of this invention are as follows:

[0033] In this invention, aquaculture tanks are set up within the aquaculture area for aquaculture operations. These tanks are designed to float in water, thus ensuring that the hull's own reinforcing ribs do not interfere with the aquaculture operations. This allows the hull's reinforcing ribs to be aligned in accordance with existing shipbuilding standards. Furthermore, this invention utilizes isolation bulkheads and longitudinal bulkheads on the hull to divide the area into several aquaculture zones for independent operations. These bulkheads and longitudinal bulkheads serve to both isolate and reinforce the hull's lateral and longitudinal strength, while also maximizing space utilization and resulting in a compact hull structure.

[0051] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described below.

[0052] Please see Figure 1-3 This invention provides a deep-sea aquaculture vessel, particularly suitable for aquaculture. The deep-sea aquaculture vessel includes a hull 100, which forms the space required for aquaculture. The hull 100 includes isolation bulkheads 1 and longitudinal bulkheads 2. Several rows of aquaculture areas 3 are separated within the hull 100. Each aquaculture area 3 operates independently. The term "independent" here refers to the aquaculture operation and does not imply absolute spatial isolation between adjacent aquaculture areas 3. In other words, adjacent aquaculture areas 3 can be completely isolated spatially, or they can be interconnected by pipes, and this connection does not affect the aquaculture operations of the two areas 3. The aquaculture areas 3 in the same row are arranged sequentially from the bow to the stern of the hull 100. Adjacent aquaculture areas 3 in the same row are isolated by isolation bulkheads 1; adjacent aquaculture areas 3 in different rows are isolated by longitudinal bulkheads 2.

[0053] The deep-sea aquaculture vessel also includes aquaculture tanks 5 for aquaculture operations. Each aquaculture tank 5 corresponds to an aquaculture area 3 and is built into the aquaculture area 3. The aquaculture tanks 5 are designed to float within the aquaculture area 3. In other words, there is a gap between the aquaculture tanks 5 and the inner wall of the aquaculture area 3. The space outside the aquaculture tanks 5 within the aquaculture area 3 is defined as the floating space 4. After water is filled into the floating space 4, the aquaculture tanks 5 can float and detach from the hardware facilities on the hull 100 structure. During aquaculture operations, the aquaculture tanks 5 usually float within the aquaculture area 3. When sewage discharge is required, the aquaculture tanks 5 can be lowered and brought into contact with the hull 100 to discharge the water inside the aquaculture tanks 5.

[0054] In this embodiment, aquaculture tanks 5 are set up in aquaculture area 3 for aquaculture operations, and aquaculture tanks 5 are set up as devices that can float in water. Therefore, the reinforcing rib structure of the hull 100 itself does not affect the aquaculture operation. Thus, the reinforcing rib structure of the hull 100 can be set up in the same direction according to existing specifications. Moreover, the water in the floating space 4 absorbs part of the force generated when the hull 100 shakes, which reduces the impact of the hull 100's shaking on the aquaculture tanks 5. In addition, since the aquaculture tanks 5 and the hull 100 are kept at a distance for most of the time during aquaculture operations, the heat preservation performance of the aquaculture tanks 5 is improved, and the frequency and cost of changing the water in the aquaculture tanks 5 are reduced.

[0055] In this embodiment, several aquaculture areas 3 are divided into several aquaculture zones 3 by using the isolation bulkhead 1 and longitudinal bulkhead 2 on the hull 100 for independent aquaculture operations. The isolation bulkhead 1 and longitudinal bulkhead 2 have the effect of isolating and strengthening the lateral and longitudinal strength of the hull 100, and the space utilization rate inside the hull 100 is large, and the structure of the hull 100 is compact.

[0056] In this embodiment of the invention, the hull 100 further includes an outer shell 6 and an inner shell 7 spaced apart. The inner shell 7 is built inside the outer shell 6 and is fixedly connected to the outer shell 6. The isolation bulkhead 1 is fixed to the inner shell 7.

[0057] In this embodiment, by setting the hull 100 to have an inner shell 7 and an outer shell 6, the strength and rigidity of the hull 100 are improved. At the same time, the space between the inner shell 7 and the outer shell 6 can be used as a ballast water tank.

[0058] In this embodiment of the invention, the hull 100 also includes a deck, the aquaculture area 3 is located below the deck, and the upper end of the longitudinal bulkhead 2 is fixedly connected to the deck.

[0059] In this embodiment, the longitudinal restraint of the longitudinal bulkhead 2 is provided directly or indirectly by the deck, which improves the strength of the hull 100.

[0060] In this embodiment of the invention, the hull 100 also includes two transverse bulkheads 8, which are located at the bow and stern of the hull 100 respectively, and each aquaculture area 3 is located between the two transverse bulkheads 8.

[0061] In this embodiment, the isolation bulkhead 1 and the longitudinal bulkhead 2 have both isolation and reinforcement effects, so only the transverse bulkhead 8 needs to be set at the bow and stern of the hull 100. As a result, the number of transverse bulkheads 8 is reduced, the weight of the main hull 100 is greatly reduced, and the cost is lower.

[0062] In this embodiment of the invention, a breeding area 3 is formed between the transverse bulkhead 8 and an isolation bulkhead 1 at the edge, or the transverse bulkhead 8 and multiple isolation bulkheads 1 in different rows at the edge respectively form breeding areas 3.

[0063] In this embodiment, an aquaculture area 3 is set between the transverse bulkhead 8 and the isolation bulkhead 1, which further expands the aquaculture space and improves the utilization rate of the space of the hull 100.

[0064] like Figure 1 As shown, in one embodiment, the hull 100 has two rows of aquaculture areas 3, and the longitudinal bulkhead 2 extends from the bow of the hull 100 to the stern of the hull 100. The two sides of the isolation bulkhead 1 are fixedly connected to the hull side and the longitudinal bulkhead 2 of the hull 100, respectively.

[0065] In this embodiment, a longitudinal bulkhead 2 is used to penetrate the bow and stern of the hull 100, which can ensure the longitudinal strength of the hull 100. The longitudinal bulkhead 2 is fixed to each isolation bulkhead 1, and also provides lateral support for the hull 100.

[0066] In one embodiment, the two rows of isolation bulkheads 1 are staggered along the longitudinal direction of the hull 100, which helps to improve the uniformity of the force on the hull 100.

[0067] like Figure 1 As shown, in one embodiment, two rows of isolation bulkheads 1 are spaced apart in the transverse direction of the hull 100, i.e., there is a gap between the opposite sides of the two rows of isolation bulkheads 1. The longitudinal bulkhead 2 has bending grooves 21 that correspond one-to-one with each aquaculture area 3. A portion of the bending grooves 21 faces one row of aquaculture areas 3, and another portion of the bending grooves 21 faces another row of aquaculture areas 3. The bending grooves 21 with different orientations are alternately arranged. The two ends of the bending grooves 21 are fixedly connected to the isolation bulkheads 1 of the corresponding aquaculture areas 3, and the middle part of the bending grooves 21 is fixedly connected to the isolation bulkheads 1 of the other row of aquaculture areas 3.

[0068] In this embodiment, the longitudinal bulkhead 2 is configured as a trough-shaped bulkhead as described above, extending from the bow to the stern of the hull 100 to provide lateral support for the hull 100 and improve the longitudinal strength of the hull 100.

[0069] In this embodiment of the invention, the two rows of aquaculture areas 3 are staggered longitudinally in the hull 100, thereby improving the space utilization rate within the hull 100. The aquaculture tanks 5 corresponding to two adjacent aquaculture areas 3 in different rows are connected by a fish-driving channel 9, which penetrates the longitudinal bulkhead 2. The fish-driving channel 9 is used to connect the two aquaculture tanks 5, allowing fish to pass through it. The fish-driving channel 9 can be a flexible hose or a rigid pipe.

[0070] In this embodiment, a fish-driving channel 9 is set up to enable the exchange of fish and water between adjacent aquaculture tanks 5. Thus, water can be injected into all aquaculture tanks 5 through one aquaculture tank 5, and fish of different sizes can be raised in different aquaculture tanks 5. For example, the fish in the aquaculture tank 5 at the bow of the hull 100 are the smallest, and the fish in the aquaculture tank 5 closer to the stern of the hull 100 are the largest. Therefore, the fish are caught at the stern of the hull 100, while the fish at the bow of the hull 100 are driven step by step to the stern of the hull 100.

[0071] In this embodiment of the invention, the aquaculture tank 5 is made of a transparent material, such as glass. In this embodiment, the glass aquaculture tank 5 has better heat retention and facilitates cleaning and observation of the fish's survival.

[0072] The aquaculture tank 5 includes a cylindrical section 51 and a spherical section 52, with the upper end of the spherical section 52 fixedly connected to the lower end of the cylindrical section 51.

[0073] In this embodiment, the lower part of the breeding tank 5 is set to a spherical shape to avoid the adhesion of feces and uneaten feed, thereby helping to ensure the water quality in the breeding tank 5.

[0074] In this embodiment of the invention, the deep-sea aquaculture vessel also includes a water injection system connected to the upper part of the aquaculture tank 5. The water injection system is used to draw water from the deep sea and inject it into the aquaculture tank 5. In this embodiment, water is injected into the aquaculture tank 5 through the water injection system to meet the water temperature requirements of the fish.

[0075] In this embodiment of the invention, the deep-sea aquaculture vessel also includes a sewage discharge system connected to the bottom of the aquaculture tank 5. The sewage discharge system is used to discharge the water in the aquaculture tank 5, thereby ensuring the water quality in the aquaculture tank 5.

[0076] In this embodiment of the invention, the deep-sea aquaculture vessel also includes a buoyancy control system. The buoyancy control system is used to regulate the water level within the floating space 4. The aquaculture tank 5 is configured to sink and trigger a discharge switch as the water level in the floating space 4 decreases, and to detach from the bottom of the hull 100 and float within the aquaculture area 3 as the water level in the floating space 4 rises. In this embodiment, controlling the height of the aquaculture tank 5 and triggering the discharge switch using the buoyancy control system simplifies the operation of the aforementioned discharge system.

[0077] In this embodiment of the invention, the deep-sea aquaculture vessel also includes an observation cabin. The isolation bulkhead 1 has a double-layered hollow structure, and the observation cabin is formed inside. The isolation bulkhead 1 has observation windows made of transparent material, allowing personnel inside the observation cabin to observe the situation inside the transparent aquaculture tank 5. In this embodiment, the observation cabin is set up using the hollow structure of the isolation bulkhead 1, so that staff can observe the growth of fish at any time, providing a basis and data for adjusting the growth environment of the fish.

[0078] In this embodiment of the invention, the deep-sea aquaculture vessel also includes an observation platform, which is located between the aquaculture tank 5 and the isolation bulkhead 1. The observation platform can be located on the upper part of the isolation bulkhead 1. In this embodiment, the observation platform facilitates the staff to monitor the operation of various equipment in the aquaculture area 3 at any time, and also enables the observation of fish growth.

[0079] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
