Description

Technical Field

[0001] This invention relates to the field of deep-sea ship engineering technology, specifically to a design method and structure for a thermal insulation structure used in a deep-sea ship cold storage. Background Technology

[0002] In the field of cold storage material applications for ships, the selection requirements and installation processes for cold storage insulation materials on conventional surface vessels such as cargo ships and passenger ships are quite mature. Cold storage insulation materials such as polyurethane foam, polystyrene, and rock wool are widely used. The installation process includes material cutting, bonding, sealing, and fixing, usually using specialized construction tools and equipment to ensure a tight fit between the materials and reduce heat leakage. For example, hot melt glue guns or mechanical fixing methods are used to install polyurethane foam, while ensuring a seal between the insulation layer and the hull structure.

[0003] However, deep-sea vessels are a type of vessel with specific functions and usage scenarios. They need to be able to operate in deep-sea waters (typically referring to waters deeper than 200 meters), possessing strong resistance to wind and waves, pressure resistance, and special designs adapted to the deep-sea environment. They are typically used for tasks such as marine resource development, scientific research, seabed resource exploration, and marine engineering support. Therefore, the performance of cold storage insulation materials used in conventional surface vessels is inherently difficult to meet the requirements of corrosion resistance to acids, alkalis, and salts in the deep-sea environment, lightweight density requirements, and low toxicity requirements for gases released over long periods. Furthermore, the installation process of cold storage insulation materials for surface vessels is difficult to adapt to the structural deformation and acoustic performance requirements of deep-sea vessels, such as vibration reduction and noise reduction.

[0004] In the prior art, such as the cold storage for ocean-going fishing vessels and its manufacturing method as described in patent number CN106741679A, the cold storage includes an outer wall of the cold storage compartment, a connecting frame, and an inner wall of the cold storage compartment. Ribs are arranged alternately on the inner surface of the outer wall of the cold storage compartment. The inner end connecting feet of the connecting frame are respectively connected to the ribs and the inner surface of the outer wall of the cold storage compartment. The inner wall of the cold storage compartment is set on the outer end of the connecting frame. The space between the outer wall and the inner wall of the cold storage compartment is filled with thermal insulation material to form a thermal insulation layer.

[0005] However, deep-sea vessels need to operate in deep-sea waters, where seawater exerts pressure on the hull plates, which is then transferred to the metal panels. If a reliable connection to the inner surface and ribs of the cold storage compartment is achieved through the connecting legs of the connecting frame, the pressure may act on the decorative panels through the connecting structure, causing damage to the decorative panels. This presents a problem that makes it difficult to design and apply to deep-sea vessels. Summary of the Invention

[0006] This application provides a design method and structure for a thermal insulation structure for a deep-sea vessel cold storage. It can solve the problem that in the prior art, deep-sea vessels need to operate in deep waters, and seawater will exert pressure on the hull plates, which will be further transferred to the metal panels. If the connecting legs of the connecting frame are used to reliably connect with the inner surface and ribs of the cold storage compartment, the pressure may act on the decorative panels through the connecting structure, causing damage to the decorative panels. This makes it difficult to design and use in deep-sea vessels.

[0007] In a first aspect, embodiments of this application provide a method for designing a thermal insulation structure for a deep-sea vessel cold storage, which includes the following steps:

[0008] A flexible thermal insulation layer and a connecting assembly are provided between a metal wall panel and a decorative panel. The connecting assembly is disposed within the flexible thermal insulation layer and includes a rigid connector and an elastic connector. One end of the rigid connector is used to connect to the outside of the metal wall panel, and the other end is connected to the elastic connector. The other end of the rigid connector is spaced apart from the decorative panel by a set distance. The elastic connector is connected to the decorative panel. When pressure acting on the metal wall panel is transmitted to the elastic connector, the elastic connector undergoes deformation and compression, and the maximum elastic compression of the elastic connector is less than the set distance.

[0009] Based on the parameters of the elastic connector, the maximum elastic compression of the elastic connector is obtained;

[0010] Based on the maximum elastic compression of the elastic connector, the range of values ​​for the set distance between the decorative panel and the end of the rigid connector is obtained.

[0011] In one embodiment, obtaining the maximum elastic compression of the elastic connector based on its parameters includes:

[0012] Based on the material of the elastic connector, the elastic deformation resistance parameter of the elastic connector is obtained, and then the maximum elastic deformation force is obtained;

[0013] The maximum elastic compression of the elastic connector is obtained based on its maximum elastic deformation force, resistance to elastic deformation parameters, height, and cross-sectional area.

[0014] In one implementation, according to the formula: Obtain the maximum elastic compression of the elastic connector;

[0015] in, This is the maximum elastic compression of the elastic connector. This is the maximum elastic deformation force of the elastic connector. The height of the elastic connector. This refers to the elastic deformation resistance parameter of the elastic connector. The cross-sectional area of ​​the elastic connector is given.

[0016] In one embodiment, after obtaining the range of values ​​for the set distance between the decorative panel and the end of the rigid connector based on the maximum elastic compression of the elastic connector, the method further includes:

[0017] Based on the parameters of the elastic connector, the maximum plastic compression of the elastic connector is obtained;

[0018] The range of values ​​for the set distance between the decorative panel and the end of the rigid connector is narrowed based on the fact that the set distance between the decorative panel and the end of the rigid connector is less than the sum of the maximum elastic compression and the maximum plastic compression of the elastic connector.

[0019] In one embodiment, the rigid connector includes two spaced-apart connecting angle steels located on both sides of the elastic connector. One end of each connecting angle steel is used to connect to the metal wall panel, and the inner side of the other end is connected to the elastic connector. The side of the elastic connector away from the decorative panel is in contact with the portion of the flexible insulation layer located between the two connecting angle steels.

[0020] In one embodiment, the elastic connector is connected to the connecting angle steel by a first self-tapping screw. The first self-tapping screw has a fracture pressure threshold. When the water pressure acting on the metal wall panel is greater than the fracture pressure threshold, the first self-tapping screw breaks. The elastic connector moves and compresses the portion of the flexible heat insulation layer located between the two connecting angle steels until the other end of the connecting angle steel abuts against the inner side of the decorative panel.

[0021] In one embodiment, before obtaining the maximum elastic compression of the elastic connector based on its parameters, the method further includes selecting the fracture pressure threshold within the pressure range where the elastic connector undergoes plastic deformation.

[0022] In one implementation, it further includes:

[0023] The fracture shear force of the first self-tapping screw is obtained based on the fracture pressure threshold.

[0024] The shear strength range of the first self-tapping screw is obtained based on the fracture shear force of the first self-tapping screw and the shear resistance area of ​​the first self-tapping screw.

[0025] The material of the first self-tapping screw is determined based on its shear strength range.

[0026] In one implementation, according to the formula: Obtain the shear strength range of the first self-tapping screw;

[0027] in, The breaking shear force of the first self-tapping screw. Let be the shear cross-sectional area of ​​the first self-tapping screw. The shear strength of the first self-tapping screw.

[0028] Secondly, this application also provides a thermal insulation structure for a deep-sea vessel cold storage, which is designed using the above-mentioned thermal insulation structure design method for a deep-sea vessel cold storage.

[0029] The beneficial effects of the technical solutions provided in this application include:

[0030] When designing the insulation structure for a deep-sea vessel cold storage, it is first determined that the insulation structure includes decorative panels, a flexible insulation layer, and connecting components. A flexible insulation layer and connecting components are installed between the metal wall panels and the decorative panels. The connecting components are located within the flexible insulation layer and include rigid and elastic connectors. One end of the rigid connector is used to connect to the outside of the metal wall panel, and the other end is connected to the elastic connector. The other end of the rigid connector is spaced a predetermined distance from the decorative panel. The elastic connector is connected to the decorative panel. When pressure acting on the metal wall panel is transmitted to the elastic connector, the elastic connector deforms and compresses, and the maximum elastic compression of the elastic connector is less than the predetermined distance. Based on the parameters of the elastic connector, the maximum elastic compression of the elastic connector is obtained. Based on the maximum elastic compression of the elastic connector, the range of set distance values ​​between the decorative panel and the end of the rigid connector is obtained. The range of set distance values ​​can be quickly obtained to select a suitable distance value, which is convenient for design. This solves the problem in the existing technology that deep-sea vessels need to operate in deep waters, where seawater will exert pressure on the hull plates and further transmit it to the metal panels. If the connection between the connecting frame and the inner surface and ribs of the cold storage warehouse are reliably connected, the pressure may act on the decorative panel through the connection structure, causing damage to the decorative panel. This makes it difficult to design and use in deep-sea vessels. Attached Figure Description

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0038] In the design and operation of deep-sea vessels, the hull structure must withstand the immense hydrostatic pressure of the deep sea. If a rigid connection is used to directly fix the hull structure to the outer wall of the cold storage insulation structure, when the hull deforms under seawater pressure, this deformation will be transmitted to the outer wall of the cold storage insulation structure through the rigid connection, causing it to bear additional stress. This stress may cause cracking, deformation, or detachment of the cold storage insulation structure, thereby compromising the integrity and insulation performance of the cold storage and making it unable to maintain the required low-temperature environment. This will directly affect the preservation effect of refrigerated goods, thus restricting the vessel's ocean-going capability and long-term operational efficiency. Therefore, designing a connection method that can reliably connect the hull structure to the outer wall of the cold storage insulation structure while effectively isolating the impact of hull deformation on the cold storage insulation structure has become a key technical challenge in the design of deep-sea vessels.

[0039] Generally speaking, the pressure of seawater first acts on the outer shell of the ship, then is transmitted from the outer shell to the platform plate, and then to the outer structure of the cold storage.

[0040] This application provides a design method and structure for a thermal insulation structure for a deep-sea vessel cold storage. It can solve the problem that in the prior art, deep-sea vessels need to operate in deep waters, and seawater will exert pressure on the hull plates, which will be further transferred to the metal panels. If the connecting feet of the connecting frame are used to reliably connect with the inner surface and ribs of the outer wall of the cold storage, the pressure may act on the decorative panels through the connecting structure, causing damage to the decorative panels. This makes it difficult to design and use in deep-sea vessels.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application provides a method for designing a thermal insulation structure for a deep-sea vessel cold storage, which includes the following steps:

[0042] A flexible heat insulation layer 1 and a connecting component 3 are provided between the metal wall panel 2 and the decorative panel 4. The connecting component 3 is disposed within the flexible heat insulation layer 1 and includes a rigid connector 31 and an elastic connector 32. One end of the rigid connector 31 is used to connect to the outside of the metal wall panel 2, and the other end is connected to the elastic connector 32. The other end of the rigid connector 31 is spaced at a set distance from the decorative panel 4. The elastic connector 32 is connected to the decorative panel 4. When the pressure acting on the metal wall panel 2 is transmitted to the elastic connector 32, the elastic connector 32 deforms and compresses, and the maximum elastic compression of the elastic connector 32 is less than the set distance.

[0043] Based on the parameters of the elastic connector 32, the maximum elastic compression of the elastic connector 32 is obtained;

[0044] Based on the maximum elastic compression of the elastic connector 32, the range of values ​​for the set distance between the decorative panel 4 and the end of the rigid connector 31 is obtained.

[0045] When designing the insulation structure for a deep-sea vessel cold storage, it is first determined that the insulation structure includes a decorative panel 4, a flexible insulation layer 1, and a connecting component 3. The flexible insulation layer 1 and the connecting component 3 are placed between the metal wall panel 2 and the decorative panel 4. The connecting component 3 is located within the flexible insulation layer 1 and includes a rigid connector 31 and an elastic connector 32. One end of the rigid connector 31 is connected to the outside of the metal wall panel 2, and the other end is connected to the elastic connector 32. The other end of the rigid connector 31 is spaced a certain distance from the decorative panel 4. The elastic connector 32 is connected to the decorative panel 4. When pressure acting on the metal wall panel 2 is transmitted to the elastic connector 32, the elastic connector 32 deforms and compresses. If the maximum elastic compression is less than the set distance, the maximum elastic compression of the elastic connector 32 is obtained based on the parameters of the elastic connector 32. Based on the maximum elastic compression of the elastic connector 32, the set distance range between the decorative panel 4 and the end of the rigid connector 31 is obtained. The set distance range can be quickly obtained to select a suitable distance value, which is convenient for design. This solves the problem in the prior art where deep-sea vessels need to operate in deep-sea waters, and seawater will exert pressure on the hull plates and further transmit it to the metal panels. If the connection between the connecting frame and the inner surface and ribs of the cold storage warehouse are reliably connected, the pressure may act on the decorative panel through the connection structure, causing damage to the decorative panel. This makes it difficult to design and use in deep-sea vessels.

[0046] In this example, the flexible connector 32 is made of timber. The metal wall panel 2 can be divided into platform panels (decks) and wall panels depending on its location.

[0047] In some optional embodiments, obtaining the maximum elastic compression of the elastic connector 32 based on its parameters includes:

[0048] Based on the material of the elastic connector 32, the elastic deformation resistance parameter of the elastic connector 32 is obtained, and then the maximum elastic deformation force is obtained;

[0049] The maximum elastic compression of the elastic connector 32 is obtained based on its maximum elastic deformation force, resistance to elastic deformation parameters, height, and cross-sectional area.

[0050] In this embodiment, obtaining the maximum elastic compression of the elastic connector 32 based on its parameters specifically includes obtaining the elastic deformation resistance parameter of the elastic connector 32 based on its material, and then obtaining the maximum elastic deformation force. Based on the maximum elastic deformation force, elastic deformation resistance parameter, height, and cross-sectional area of ​​the elastic connector 32, the maximum elastic compression of the elastic connector 32 is obtained. This allows for the rapid determination of the set distance range, enabling the selection of a suitable distance value for convenient design. It solves the problem in the prior art where deep-sea vessels need to operate in deep-sea waters, where seawater exerts pressure on the hull plates and further transmits it to the metal panels. If a reliable connection to the inner surface and ribs of the cold storage warehouse is achieved through the connecting feet of the connecting frame, the pressure may act on the decorative panels through the connecting structure, causing damage to the decorative panels. This presents a problem that makes it difficult to design and apply in deep-sea vessels.

[0051] In some alternative embodiments, according to the formula: Obtain the maximum elastic compression of the elastic connector 32;

[0052] in, This represents the maximum elastic compression of the elastic connector 32. This represents the maximum elastic deformation force of the elastic connector 32. The height of the elastic connector 32 The elastic deformation resistance parameter of the elastic connector 32 This is the cross-sectional area of ​​the elastic connector 32.

[0053] In this embodiment, according to the formula: Obtain the maximum elastic compression of the elastic connector 32, wherein, This represents the maximum elastic compression of the elastic connector 32. This represents the maximum elastic deformation force of the elastic connector 32. The height of the elastic connector 32 The elastic deformation resistance parameter of the elastic connector 32 The cross-sectional area of ​​the elastic connector 32 can be used to quickly determine the maximum elastic compression of the elastic connector 32, which is convenient for design.

[0054] In some optional embodiments, after obtaining the set distance range between the decorative panel 4 and the end of the rigid connector 31 based on the maximum elastic compression of the elastic connector 32, the method further includes:

[0055] Based on the parameters of the elastic connector 32, the maximum plastic compression of the elastic connector 32 is obtained;

[0056] Since the set distance between the decorative panel 4 and the end of the rigid connector 31 is less than the sum of the maximum elastic compression and the maximum plastic compression of the elastic connector 32, the range of values ​​for the set distance between the decorative panel 4 and the end of the rigid connector 31 is narrowed.

[0057] In this embodiment, after obtaining the set distance range between the decorative panel 4 and the end of the rigid connector 31 based on the maximum elastic compression of the elastic connector 32, it is also necessary to obtain the maximum plastic compression of the elastic connector 32 based on the parameters of the elastic connector 32. Since the set distance between the decorative panel 4 and the end of the rigid connector 31 is less than the sum of the maximum elastic compression and the maximum plastic compression of the elastic connector 32, the set distance range between the decorative panel 4 and the end of the rigid connector 31 is narrowed, which can yield a more suitable range and prevent the elastic connector 32 from being completely destroyed.

[0058] In some optional embodiments, the rigid connector 31 includes two spaced-apart connecting angle steels 311 located on both sides of the elastic connector 32. One end of the connecting angle steel 311 is used to connect to the metal wall panel 2, and the inner side of the other end is connected to the elastic connector 32. The side of the elastic connector 32 away from the decorative panel 4 is in contact with the portion of the flexible heat insulation layer 1 located between the two connecting angle steels 311.

[0059] In this embodiment, the structure of the rigid connector 31 is specifically described. The rigid connector 31 includes two spaced-apart connecting angle steels 311. The two connecting angle steels 311 are located on both sides of the elastic connector 32. One end of the connecting angle steel 311 is used to connect to the metal wall panel 2, and the inner side of the other end is connected to the elastic connector 32. The side of the elastic connector 32 away from the decorative panel 4 is in contact with the flexible heat insulation layer 1 located between the two connecting angle steels 311, which provides more deformation space for the elastic connector 32 and makes it more stable.

[0060] In some alternative embodiments, the elastic connector 32 is connected to the connecting angle steel 311 by a first self-tapping screw 5. The first self-tapping screw 5 is provided with a fracture pressure threshold. When the water pressure acting on the metal wall panel 2 is greater than the fracture pressure threshold, the first self-tapping screw 5 breaks, and the elastic connector 32 moves to compress the portion of the flexible heat insulation layer 1 located between the two connecting angle steels 311 until the other end of the connecting angle steel 311 abuts against the inner side of the decorative panel 4.

[0061] In this embodiment, the elastic connector 32 is connected to the connecting angle steel 311 by the first self-tapping screw 5. The first self-tapping screw 5 is provided with a fracture pressure threshold. When the pressure acting on the metal wall panel 2 is greater than the fracture pressure threshold, the first self-tapping screw 5 breaks. The elastic connector 32 moves and compresses the part of the flexible heat insulation layer 1 located between the two connecting angle steels 311 until the other end of the connecting angle steel 311 abuts against the inner side of the decorative panel 4 to prevent the elastic connector 32 from being excessively deformed and affecting the basic heat insulation effect of the flexible heat insulation layer 1. When the pressure acting on the metal wall panel 2 is greater than the fracture pressure threshold, the connecting component 3 becomes a rigid connection to prioritize the basic heat insulation effect.

[0062] In some optional embodiments, before obtaining the maximum elastic compression of the elastic connector 32 based on the parameters of the elastic connector 32, the method further includes selecting a fracture pressure threshold within the pressure range in which the elastic connector 32 undergoes plastic deformation.

[0063] In this embodiment, a fracture pressure threshold is selected within the pressure range during which the elastic connector 32 undergoes plastic deformation to prevent the first self-tapping screw 5 from breaking during the elastic deformation of the elastic connector 32, thereby reducing the stability of the entire device.

[0064] In some optional embodiments, it also includes:

[0065] The fracture shear force of the first self-tapping screw 5 is obtained based on the fracture pressure threshold.

[0066] Based on the fracture shear force of the first self-tapping screw 5 and the shear resistance area of ​​the first self-tapping screw 5, the shear strength range of the first self-tapping screw 5 is obtained.

[0067] The material of the first self-tapping screw 5 is determined based on the shear strength range of the first self-tapping screw 5.

[0068] In this embodiment, when designing the insulation structure for the deep-sea ship cold storage, the fracture shear force of the first self-tapping screw 5 is obtained according to the fracture pressure threshold. Based on the fracture shear force of the first self-tapping screw 5 and the shear resistance area of ​​the first self-tapping screw 5, the shear strength range of the first self-tapping screw 5 is obtained. Based on the shear strength range of the first self-tapping screw 5, the material of the first self-tapping screw 5 is determined. The material of the first self-tapping screw 5 can be determined quickly, which is convenient for design.

[0069] In some alternative embodiments, according to the formula: Obtain the shear strength range of the first self-tapping screw 5;

[0070] in, The breaking shear force of the first self-tapping screw 5. This represents the shear cross-sectional area of ​​the first self-tapping screw 5. The shear strength of the first self-tapping screw 5.

[0071] In this embodiment, according to the formula: Obtain the shear strength range of the first self-tapping screw 5, where, The breaking shear force of the first self-tapping screw 5. This represents the shear cross-sectional area of ​​the first self-tapping screw 5. The shear strength of the first self-tapping screw 5 allows for quick determination of its material, facilitating design.

[0072] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, on the other hand, this application also provides a thermal insulation structure for a deep-sea vessel cold storage, which is designed using the above-mentioned thermal insulation structure design method for a deep-sea vessel cold storage.

[0073] When designing the insulation structure for a deep-sea vessel cold storage, it is first determined that the insulation structure includes a decorative panel 4, a flexible insulation layer 1, and a connecting component 3. The flexible insulation layer 1 and the connecting component 3 are placed between the metal wall panel 2 and the decorative panel 4. The connecting component 3 is located within the flexible insulation layer 1 and includes a rigid connector 31 and an elastic connector 32. One end of the rigid connector 31 is connected to the outside of the metal wall panel 2, and the other end is connected to the elastic connector 32. The other end of the rigid connector 31 is spaced a certain distance from the decorative panel 4. The elastic connector 32 is connected to the decorative panel 4. When pressure acting on the metal wall panel 2 is transmitted to the elastic connector 32, the elastic connector 32 deforms and compresses. If the maximum elastic compression is less than the set distance, the maximum elastic compression of the elastic connector 32 is obtained based on the parameters of the elastic connector 32. Based on the maximum elastic compression of the elastic connector 32, the set distance range between the decorative panel 4 and the end of the rigid connector 31 is obtained. The set distance range can be quickly obtained to select a suitable distance value, which is convenient for design. This solves the problem in the prior art where deep-sea vessels need to operate in deep-sea waters, and seawater will exert pressure on the hull plates and further transmit it to the metal panels. If the connection between the connecting frame and the inner surface and ribs of the cold storage warehouse are reliably connected, the pressure may act on the decorative panel through the connection structure, causing damage to the decorative panel. This makes it difficult to design and use in deep-sea vessels.

[0074] In this example, in another structural form, the rigid connector 31 includes a support section 312 and a connecting section 313. The support section 312 is used to connect with the metal wall panel 2, and the connecting section 313 has a U-shaped cross section. The elastic connector 32 is set in the opening of the connecting section 313. The structure is relatively simple and easy to install.

[0075] In this example, the decorative panel 4 includes a composite panel 41 and a metal panel 42. The inner side of the composite panel 41 is connected to the flexible heat insulation layer 1, and the metal panel 42 is disposed on the outer side of the composite panel 41 to ensure the stability of the decorative panel 4.

[0076] In this example, the composite panel 41 and the metal panel 42 are connected by a surface adhesive 9.

[0077] In this example, the insulation structure for the deep-sea vessel cold storage also includes a second self-tapping screw 6, which passes through the composite plate 41 and the metal plate 42 and is anchored in the elastic connector 32, facilitating the connection between the elastic connector 32 and the decorative plate 4, and further ensuring the connection stability between the composite plate 41 and the metal plate 42.

[0078] In this example, a damping waterproof layer 7 is provided between the flexible insulation layer 1 and the metal wall panel 2, as well as between the flexible insulation layer 1 and the decorative panel 4. The rigid connector 31 passes through the damping waterproof layer 7 to connect with the metal wall panel 2, thereby improving the waterproof performance.

[0079] In this example, the damping waterproof layer 7 is connected to the metal wall panel 2 by the underlayer adhesive 8.

[0080] In summary, current connection methods for cold storage insulation structures on ocean-going fishing vessels do not consider lateral fixing at the connection angles. This is because conventional surface vessels are largely unaffected by water pressure deformation, resulting in minimal deformation of the internal metal panels and bulkheads. Therefore, rigid connections or modular cold storage insulation structures can be used. However, deep-sea vessels are limited by their hull size (limited space restricts the installation of modular structures) and working environment (high pressure at sea causes hull deformation, making rigid connections impossible). Furthermore, they must meet acoustic performance requirements for vibration and noise reduction (rigid connections exacerbate vibration and noise transmission). Therefore, a structure that balances structural stability, vibration and noise reduction, and ease of installation, as proposed in this application, must be designed specifically for the unique operating conditions of deep-sea vessels.
