Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more particularly to a truss-type aquaculture vessel. Background Technology

[0002] Developing deep-sea aquaculture equipment is an important way for countries to improve the safety of their aquaculture industries. Norway, Japan, the United States, and other countries are actively engaged in the research and development of deep-sea aquaculture equipment, and my country is also actively developing its aquaculture equipment industry. In recent years, my country has carried out many practices and explorations in this area, and has initially formed two major categories of deep-sea aquaculture equipment: semi-submersible fixed aquaculture platforms and ship-mounted aquaculture vessels.

[0003] Traditional aquaculture vessels use electric pumps for water exchange in the aquaculture tanks, but this method suffers from drawbacks such as high initial investment, high energy consumption, and low return on investment. Semi-submersible fixed aquaculture platforms, on the other hand, lack self-propulsion, are susceptible to water pollution, and are vulnerable to typhoons. To address these shortcomings of deep-sea aquaculture equipment, a self-propelled truss-type aquaculture vessel has been developed. This vessel's main structure consists of trusses, with large openings on the sides, bottom, and stern for natural water exchange in the aquaculture tanks. However, traditional engine room layouts are no longer suitable for the safety, environmental, and efficiency requirements of these self-propelled truss-type aquaculture vessels. If a traditional engine room is installed at the stern using existing layouts, the entire stern space would be occupied by the engine room. Furthermore, the inability to create large openings at the stern negatively impacts the water volume and natural water exchange in the aquaculture tanks. In addition, due to the structural characteristics of the truss-type aquaculture vessel, this design will also lead to two serious problems: 1. There will be a significant shear force change at the forward wall of the engine room, resulting in excessive shear force; 2. It will be difficult to balance buoyancy between the engine room area and the aquaculture area. The buoyancy in the engine room area will be large, while the buoyancy in the aquaculture area will be small. In addition to severe bow tilting, once the engine room is damaged and flooded, the stability will not meet the safety requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a truss-type aquaculture vessel that can balance the buoyancy at the stern of the vessel, reduce the shear force on the forward wall of the engine room, optimize the weight of the steel, and overcome the safety defects caused by excessive shear force and excessive buoyancy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A truss-type aquaculture vessel is provided, comprising a stern section, the stern section including a bottom plate, a first deck, and a second deck arranged sequentially from bottom to top, with sea level located between the first deck and the second deck. An engine room is disposed between the bottom plate and the first deck, the engine room being located at the stern of the stern section and housing a propulsion assembly. A superstructure is disposed above the second deck, the superstructure being located at the stern of the stern section and housing a control room. An aquaculture tank is disposed between the first deck and the second deck, the end of the aquaculture tank away from the stern of the stern section extending to the bottom plate, and the sidewalls and / or bottom of the aquaculture tank having openings communicating with the ocean.

[0007] As a preferred embodiment of a truss-type aquaculture vessel, the stern section further includes load-bearing columns, which are hollow columns, and the cavities of the load-bearing columns are connected to the engine room and the superstructure, respectively.

[0008] As a preferred embodiment of a truss-type aquaculture vessel, at least two load-bearing columns are provided, and the at least two load-bearing columns are a first column and a second column, respectively.

[0009] The cavity of the first column serves as a first air duct, which connects to the fan room within the upper structure; and / or,

[0010] A staircase is installed inside the cavity of the second column.

[0011] As a preferred option for truss-type aquaculture vessels, the top of the first air duct is provided with a lifting port.

[0012] As a preferred embodiment of a truss-type aquaculture vessel, the stern section has a first axis extending along the length of the stern section, and the first column is located on the first axis.

[0013] As a preferred embodiment of the truss-type aquaculture vessel, the load-bearing column further includes a third column, the cavity of which serves as a second air duct, and the two ends of the fan room are respectively connected to the first air duct and the second air duct.

[0014] As a preferred embodiment of the truss-type aquaculture vessel, the load-bearing column further includes a fourth column, and an exhaust pipe is provided in the cavity of the fourth column.

[0015] As a preferred embodiment of a truss-type aquaculture vessel, a seawater tank is installed in the engine room, the bottom of which is connected to the ocean, and the seawater tank is connected to the cooling system and fire protection system of the truss-type aquaculture vessel through a seawater main pipe.

[0016] As a preferred embodiment of a truss-type aquaculture vessel, the stern section has a first axis extending along the length of the stern section, and two seawater tanks are provided, which are symmetrically arranged about the first axis.

[0017] As a preferred embodiment of a truss-type aquaculture vessel, a liquid tank is also provided between the bottom plate and the first deck, and the liquid tank is located at the stern of the stern section.

[0018] The beneficial effects of this invention are as follows: By constructing a superstructure on the second deck of the stern section, the space occupied by the engine room between the first and second decks is reduced, thereby decreasing the volume of the engine room's floating body and preventing sudden shear force changes, thus reducing the shear force on the engine room's forward wall. Furthermore, by setting up an aquaculture tank between the first and second decks, the aquaculture tank can extend to the stern of the stern section, increasing its area and reducing buoyancy at the stern, thus preventing severe bow tilt and ensuring the ship's stability is maintained in the event of engine room damage and flooding.

[0028] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1 to 6As shown, the present invention provides a truss-type aquaculture vessel, including a stern section. The stern section includes a bottom plate 1, a first deck 2, and a second deck 3 arranged sequentially from bottom to top. The sea level is located between the first deck 2 and the second deck 3. An engine room 4 is arranged between the bottom plate 1 and the first deck 2. The engine room 4 is located at the stern of the stern section and contains a power propulsion assembly. A superstructure 6 is arranged above the second deck 3. The superstructure 6 is located at the stern of the stern section and contains a central control room 62. An aquaculture tank 10 is arranged between the first deck 2 and the second deck 3. The end of the aquaculture tank 10 away from the stern of the vessel extends to the bottom plate 1. The side walls and / or bottom of the aquaculture tank 10 are provided with openings 101 communicating with the ocean. In this embodiment, the engine room 4 is located below sea level and at the stern of the stern section. Therefore, the buoyancy at the stern of the stern section is greater. Since the end of the aquaculture tank 10 furthest from the stern extends to the bottom plate 1, the shear force is greatest at the junction of the aquaculture tank 10 and the engine room 4. A superstructure 6 is installed on the second deck 3 of the stern section, and the superstructure 6 is located at the stern of the stern section, above the engine room 4. By reducing the space occupied by the engine room between the first deck 2 and the second deck 3, the volume of the floating body of the engine room 4 is reduced, avoiding sudden shear force changes and reducing the shear force on the forward wall of the engine room 4. By setting the aquaculture tank 10 between the first deck 2 and the second deck 3, the aquaculture tank 10 can extend to the stern of the stern section, increasing its range and reducing the buoyancy at the stern of the stern section. This prevents severe bow tilt and avoids affecting the ship's stability should the engine room 4 be damaged and flooded.

[0031] Furthermore, the stern section also includes a load-bearing column 5, which is a hollow column. The cavity of the load-bearing column 5 is connected to the engine room 4 and the superstructure 6. It is understandable that the load-bearing column 5 is an essential structure of the ship. By setting the load-bearing column 5 as a hollow column, the space occupied by the load-bearing column 5 can be utilized, thereby maximizing the area of ​​the aquaculture tank 10.

[0032] Furthermore, at least two load-bearing columns 5 are provided, namely a first column 51 and a second column 52; the cavity of the first column 51 serves as a first air duct, which connects to the fan room 61 in the superstructure 6; a staircase is provided in the cavity of the second column 52. By setting the cavity of the first column 51 as the first air duct, ventilation can be provided for the engine room 4; the staircase in the cavity of the second column 52 facilitates crew access to the engine room 4 for maintenance of the equipment inside.

[0033] Furthermore, a lifting port is provided at the top of the first air duct. By providing the lifting port, heavy equipment can be moved by cranes at the shore dock, thus facilitating the transport of equipment and materials inside the engine room 4.

[0034] Furthermore, the stern section has a first axis extending along its length, and both the first column 51 and the second column 52 are located on this first axis. It is understood that the swaying amplitude of the ship is greatest on its left and right sides, and smallest on its central axis. Placing the second column 52 on the first axis reduces the swaying amplitude of the stairs, thereby improving the safety of crew members walking and working on the stairs.

[0035] Furthermore, the load-bearing column 5 also includes a third column 53, the cavity of which serves as a second air duct. The two ends of the fan room 61 are connected to the first and second air ducts, respectively. In this embodiment, the length of the fan room 61 extends along the width direction of the stern section. Three ventilation fans 11 are installed inside the fan room 61, spaced apart along the width direction of the stern section. The use of the cavity of the third column 53 as a second air duct enhances the ventilation effect on the engine room 4.

[0036] Furthermore, the load-bearing column 5 also includes a fourth column 54, and an exhaust pipe 12 is installed in the cavity of the fourth column 54. In this embodiment, the power propulsion components in the engine room 4 include electrical equipment such as generators and diesel engines. It is understood that the diesel engine will release exhaust gas when it is operating. The exhaust pipe 12 is installed in the cavity of the fourth column 54, so that air can enter the engine room 4 from the first air duct and the second air duct, and then be discharged from the exhaust pipe 12 of the fourth column 54. This can prevent exhaust gas from entering the central control room 62.

[0037] In this embodiment, a total of six load-bearing columns 5 are provided, namely the first column 51, the second column 52, the third column 53, the fourth column 54, the fifth column 55, and the sixth column 56. The fifth column 55 also has an exhaust pipe 12 installed inside its cavity. The fifth column 55 and the fourth column 54 are located on opposite sides of the first axis and are symmetrical about the first axis. The sixth column 56 has an escape passage installed inside its cavity. Silencers are also installed inside the fourth column 54 and the fifth column 55 to reduce noise generated by airflow.

[0038] Furthermore, a seawater tank 41 is installed inside the engine room 4. The bottom of the seawater tank 41 is connected to the ocean, and the seawater tank 41 is connected to the cooling system and fire protection system of the truss-type aquaculture vessel via a seawater main pipe 13. In this embodiment, the bottom plate 1 separates the engine room 4 from the ocean. The seawater tank 41 installed inside the engine room 4 allows for convenient extraction of seawater. The seawater has a lower temperature, and the extracted seawater can be used to cool the equipment and for the fire protection system of the truss-type aquaculture vessel.

[0039] Furthermore, two seawater tanks 41 are provided, and the two seawater tanks 41 are symmetrically arranged about the first axis. By providing two seawater tanks 41, water can be easily drawn.

[0040] Furthermore, a liquid tank 8 is provided between the bottom plate 1 and the first deck 2. The liquid tank 8 is located at the stern of the stern section and includes a fuel oil storage tank 81, a fuel oil day tank 82, a sludge oil tank 83, and a bilge water tank 84. Since the liquid tank 8 is located between the bottom plate 1 and the first deck 2, and at the stern of the stern section, and is below sea level, it is understood that the liquid tank 8 stores liquid materials such as fuel oil and sludge oil.

[0041] In general, this embodiment divides the stern section of the truss-type aquaculture vessel into three parts. The first part extends from the bottom plate 1 to the first deck 2. The sides of this part are used to house liquid tanks 8 such as fuel oil storage tanks 81, fuel oil day tanks 82, sludge tanks 83, and bilge water tanks 84. The middle part is the engine room 4, which houses two propulsion diesel engines 91 (main engines), each connected to a fully azimuth propeller via a short shaft and coupling, used to drive the vessel forward or backward. Between the two propulsion diesel engines 91 are two main generator sets 92, used to provide power to the vessel. A seawater tank 41 is located on each of the port and starboard sides at the bow, connected by a seawater main pipe 13, used to provide seawater for cooling water pumps and fire pumps. Other auxiliary equipment serving the propulsion diesel engines 91 and main generator sets 92 is distributed separately. The first deck 2 is a deck extending from the port side to the starboard side of the vessel, forming the top of the engine room 4. The height of the first deck 2 should be reduced as much as possible while still meeting the cylinder lifting height requirements of the propulsion diesel engine 91, so as to reduce the volume of the engine room 4 and the buoyancy at the tail, and expand the aquaculture water body.

[0042] The second section extends from the first deck 2 to the second deck 3. The six load-bearing columns 5 in this section are distributed on the left, right, and middle sides of the forward and aft sections of the engine room 4, utilizing the ship's existing truss structure. The three forward load-bearing columns 5, from left to right, are the fourth column 54, the second column 52, and the fifth column 55. The cavities of the fourth and fifth columns 54 and 55 are used to house the exhaust pipes 12 and silencers for ventilation and heat dissipation in the engine room 4. The cavity of the second column 52 is used to house the inclined ladder for entering and exiting the engine room 4. The three aft load-bearing columns 5, from left to right, are the sixth column 56, the first column 51, and the third column 53. The cavity of the sixth column 56 serves as an escape route, the cavity of the third column 53 as a second ventilation duct, and the cavity of the first column 51 as both the first ventilation duct and cargo hoisting passage for the engine room 4. In addition to the six load-bearing columns 5, an aquaculture tank 10 is located between the first deck 2 and the second deck 3 at the stern. This aquaculture tank 10 retains openings 101 on both sides and at the stern to prevent poor water exchange. It also significantly reduces the floating body at the stern of the ship and reduces the shear force on the forward wall of the engine room 4.

[0043] The third section is located above the second deck 3. It mainly consists of the superstructure 6, which houses the fan room 61, control room 62, engine room 63, auxiliary equipment room 64, electrical equipment room 65, central air conditioning room 66, and stairwell 67. The fan room 61 houses the fans, the control room 62 houses the switchboard and control console, the engine room 63 houses the engine repair equipment, and the auxiliary equipment room 64 houses the air compressor and air cylinders, among other auxiliary equipment. A miniature chimney is located on each of the port and starboard sides, housing the exhaust pipe 12 and the engine room 4 ventilation grilles. The fan room 61 contains three fans, connected to the first and second ventilation ducts on both sides via nacelles below the second deck 3. When the ship is underway, all three fans are simultaneously activated, supplying air to the engine room 4 through the first and second ventilation ducts to provide combustion air for the diesel engines 91 and the main generator set 92, and to provide the necessary airflow for cooling and ventilation in the engine room 4. When the vessel is not sailing, only the rightmost ventilation fan 11 needs to be turned on to supply air to the engine room 4 through the second air duct, providing the main generator set 92 with the combustion air and the air volume required for heat dissipation and ventilation in the engine room 4. Since the truss-type aquaculture vessel is in aquaculture mode most of the time, i.e., not sailing, this setup saves on the power consumption of the fans.
