Description

Manufacturing method and system for spherical pressure-resistant structures for implosion protection of deep-sea submersibles Technical Field

[0001] This invention relates to the technical field of manufacturing and performance testing of deep-sea pressure-resistant structures, specifically, to a method for manufacturing an implosion-protective spherical pressure-resistant structure suitable for deep-sea submersibles. Background Technology

[0002] As an essential technical equipment for exploration, the deep-sea submersible's pressure-resistant structure, a crucial component, ensures the safety of personnel and equipment.

[0003] To further develop deep-sea resources, advanced deep-sea submersibles are needed to complete exploration missions. However, the high-pressure working environment of the deep sea places high demands on the pressure resistance of the structure, and the huge pressure difference between the inside and outside of the hollow spherical structure poses a risk of implosion. During implosion, the hydrostatic pressure of the flow field is converted into fluid kinetic energy. When the airflow compresses the internal air cavity to its minimum, the internal air will rebound outward, generating a shock wave far exceeding the environmental pressure, causing catastrophic consequences. Therefore, multiple factors need to be considered when designing and manufacturing deep-sea submersibles.

[0004] In terms of design and material selection, combining two materials and laying fiber prepreg on the outside of the pressure-resistant liner can achieve implosion protection while meeting the pressure-bearing function of the deep-sea submersible. Regarding structural morphology, a spherical structure, due to its perfectly symmetrical geometry, can evenly distribute the external force of water across the structure, and is considered the ideal shape for the flotation device of a deep-sea submersible. Therefore, using a spherical pressure-resistant structure combining prepreg and liner on actual submersibles is considered a good solution.

[0005] However, the requirements of the deep-sea working environment for an ideal hollow sphere are difficult to meet with conventional manufacturing methods. In traditional processing methods, carbon fiber winding requires a fulcrum; however, for a spherical pressure-resistant structure, the location of the fulcrum is difficult to find, making it difficult to control the roundness of the overall structure. At the same time, the adhesion between the liner and the prepreg, and between the prepreg layers, as well as the smoothness of the overall structure, are also challenges that remain to be solved in previous processing methods. Furthermore, since this spherical pressure-resistant structure is intended for deep-sea submersibles, it first needs to have pressure resistance to meet the pressure requirements of the deep-sea working environment. Additionally, the structure itself must also have protective performance in the event of a deep-sea implosion.

[0006] In summary, it is necessary to propose a manufacturing method for an implosion-resistant pressure-resistant structure suitable for deep-sea submersibles. This method should meet the requirements of the deep-sea working environment, as well as the structural requirements for roundness, smoothness, fit, and protective performance. Furthermore, the manufactured structure should be tested according to requirements to achieve overall performance evaluation. This solution has significant engineering reference value for the design and manufacture of deep-sea submersibles.

[0007] Existing Chinese patent application CN117465640A discloses a lightweight composite spherical pressure-resistant structure and a deep-sea submersible for deep-sea implosion protection. The structure includes a hollow ceramic sphere liner and a CFRP outer layer, with the CFRP outer layer covering the outer surface of the hollow ceramic sphere liner. The two components together form a ceramic-CFRP composite spherical pressure-resistant structure. However, this patent only proposes a novel structural concept; it does not provide a manufacturing method for the structure, nor does it produce a physical prototype or propose a set of testing and inspection methods for the structure.

[0008] The existing design has the following drawbacks: during actual manufacturing, the hollow ceramic sphere liner and the CFRP outer layer are not tightly bonded; the CFRP outer layer becomes uneven due to fiber bundle entanglement; and the overall roundness of the structure is difficult to control. Furthermore, because this structure is intended for use in deep-sea submersibles, characterized by high environmental pressure and a high risk of implosion, these shortcomings will significantly impact the final performance. Additionally, after manufacturing, a corresponding performance testing plan is needed to evaluate the structural performance. However, there is currently no experimental testing plan specifically addressing the pressure-resistant structure's inherent performance and implosion protection capabilities for deep-sea submersibles.

[0009] Therefore, a new technical solution is needed to improve the above-mentioned technical problems. Summary of the Invention

[0010] To address the shortcomings of existing technologies, the purpose of this invention is to provide a manufacturing method and system for an implosion-resistant spherical pressure-resistant structure suitable for deep-sea submersibles.

[0058] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0059] Example 1

[0060] This invention provides a method for manufacturing an implosion-proof spherical pressure-resistant structure suitable for deep-sea submersibles. It aims to address the problems of traditional methods being unable to meet the manufacturing requirements of such structures and the lack of corresponding performance testing methods. Referring to Figure 1, the method specifically includes: a method for manufacturing the implosion-proof spherical pressure-resistant structure suitable for deep-sea submersibles using a molding process, and a performance testing method that assesses both the structure's inherent performance indicators and its protective effect under simulated deep-sea conditions.

[0061] The wall thickness S1 of the hollow ceramic spherical pressure-resistant structure should be selected based on the actual operating water depth. When the deep-sea submersible is operating, the operating water depth h needs to be given; this embodiment takes the Mariana Trench, the deepest known ocean, as the actual operating condition, with an operating water depth of 11,000m.

[0062] The manufacturing method of the spherical pressure-resistant structure for implosion protection of deep-sea submersibles includes the following steps: S1 Prepreg cutting; S2 Prepreg laying; S3 Pre-vacuum treatment; S4 Polishing treatment.

[0063] Before processing in step S1, the prepreg is first cut into eight equal parts and laid out, as shown in Figure 2. Multiple layers are laid out, with the number of layers n ranging from 5 to n to 10. The roundness of the overall structure is ensured by gradually increasing the cut area S of each layer.

[0064] The cutting area S of each layer is selected according to the designed number of layers n. In this embodiment, n = 5 is used as the designed number of layers. The radius r of the inner hollow sphere is 92mm, the total number of prepreg layers is 5, and the total thickness N of the prepreg layers is 1.5mm. As shown in Figure 3.

[0065] The first layer of prepreg closest to the liner is defined as "layer 1", the second layer of prepreg as "layer 2", the third layer of prepreg as "layer 3", the fourth layer of prepreg as "layer 4", and the fifth layer of prepreg as "layer 5".

[0066] The cut area S1 of the eight equal parts of the "1 layer" prepreg is:

[0067] The cut area S2 of the "2-layer" eight-part prepreg is:

[0068] The cut area S3 of the "3-layer" eight-part prepreg is:

[0069] The cut area S4 of the "4-layer" eight-part prepreg is:

[0070] The cut area S5 of the 8 equal parts of the "5-layer" prepreg is:

[0071] In step S2, before laying the prepreg, epoxy resin is evenly applied to the lining, and then the prepreg is laid. This ensures good adhesion between the lining and the prepreg.

[0072] Step S3 involves performing a pre-vacuuming process after each layer is laid to ensure the adhesion between the prepreg layers and the overall roundness. This process is repeated until multi-layer processing is achieved.

[0073] Step S4 involves polishing after multi-layer processing to meet the surface smoothness requirements of the spherical pressure-resistant structure for implosion protection of deep-sea submersibles.

[0074] Finally, a physical prototype of an implosion-protective spherical pressure-resistant structure suitable for deep-sea submersibles, as shown in Figure 4, was manufactured.

[0075] The testing method for the implosion protection spherical pressure-resistant structure applicable to deep-sea submersibles includes: performance testing from two aspects: the performance indicators of the structure itself and the protective effect under simulated deep-sea environment.

[0076] The performance indicators of the structure in the detection method are the roundness, smoothness, and fit of the overall structure. The dimensions of the overall structure were calibrated and measured using vernier calipers, revealing that the overall roundness, fit, and smoothness were good.

[0077] The method for simulating the deep-sea environment is to use static water pressurization to simulate the pressure under deep-sea working conditions.

[0078] The actual operating water depth h of the deep-sea submersible; in this embodiment, an operating water depth of 1500m is selected, then the static pressure P of the water surrounding the pressure-resistant structure under the operating water depth conditions. water For: P water =ρgh=15MPa (6)

[0079] The experimental hydrostatic pressure P reached by applying hydrostatic pressure is... test For: P test =P water =15MPa (7)

[0080] This simulates the pressure under actual working conditions in the deep sea.

[0081] The structure was pressurized to 15 MPa under hydrostatic pressure and subjected to a pressure test, which showed that the structure remained stable. Next, a comparative experiment was conducted with a spherical structure with the same lining to evaluate the protective performance. The peak dynamic pressure captured by the pressure sensor was P. result .

[0082] For the spherical pressure-resistant structure for implosion protection of deep-sea submersibles proposed in this invention, the peak dynamic pressure captured by the pressure sensor is P. result1 For a spherical structure with the same liner, the peak dynamic pressure captured by the pressure sensor is P. result2 The resulting diagram illustrating the relationship between pressure and time is shown in Figure 5.

[0083] The effectiveness of implosion protection can be evaluated using the peak pressure reduction rate α, which can be substituted into the calculation formula as follows:

[0084] The pressure peak reduction rate 'a' reached 80%, proving that the implosion protection effect is good. In summary, the technical solution of this invention has good impact resistance and protective effect.

[0085] The manufacturing method for the implosion-resistant spherical pressure-resistant structure provided by this invention improves upon commonly used manufacturing and testing methods in current engineering. Furthermore, the following conclusions can be drawn: Through five steps—S1 prepreg cutting; S2 prepreg laying; S3 pre-vacuum treatment; S4 polishing; and S5 performance testing—the method solves the problem of traditional manufacturing methods failing to meet requirements for roundness, smoothness, and fit. The resulting embodiment exhibits outstanding performance in both structural integrity and implosion protection. Clearly, this invention provides a new solution for the manufacturing of deep-sea pressure-resistant structures and is of great significance for the design, manufacturing, and testing of deep-sea submersibles and deep-sea pressure-resistant structures.

[0086] In summary, the lightweight composite spherical pressure-resistant structure for deep-sea implosion protection described in this embodiment improves upon commonly used manufacturing methods in current engineering. It utilizes a molding process to achieve a manufacturing method suitable for deep-sea submersibles, and provides a performance testing method that assesses both the structure's inherent performance indicators and its protective effect under simulated deep-sea conditions. This overcomes the limitations of traditional methods in meeting manufacturing requirements. Experimental testing shows that this embodiment successfully manufactures physical structures according to the manufacturing scheme. Furthermore, testing demonstrates that the structure manufactured in this embodiment meets the requirements for roundness, smoothness, and fit while improving the pressure peak reduction rate, resulting in good implosion protection. The method employed in this embodiment is simple, provides significant protection, and achieves multiple benefits including feasibility and safety.
