Description

Technical Field

[0001] This invention relates to the field of underwater detection equipment technology, specifically to an underwater multi-load constant temperature sealed chamber device. Background Technology

[0002] In the field of underwater detection equipment, sealed enclosure technology, as a core protection method, has seen considerable development and application. Traditional underwater sealed enclosure equipment mainly adopts a cylindrical structure, equipped with basic sealing cover components and thermal conductive designs, aiming to provide a pressure-resistant and waterproof environment for internal electronic equipment. These devices are typically constructed of a metal shell, with modular installation achieved through simple support frames and heat-conducting plates. However, the structure is relatively simple and cannot accommodate multiple types of loads simultaneously. Existing sealed enclosures focus on basic sealing performance in their design, such as using rubber rings and bolt connections to resist water pressure, but rely on limited air convection and contact heat transfer for heat dissipation, resulting in low heat conduction efficiency. Especially in deep-water environments, the temperature maintenance of the sealed enclosure mainly relies on passive heat dissipation, lacking an efficient thermal management mechanism, which can easily affect the stability of the equipment due to internal temperature accumulation. In addition, they have poor versatility; most devices are designed only for specific detection modules and cannot flexibly adapt to different wavebands or functional loads, limiting their practicality in integrated detection missions.

[0003] The shortcomings of existing technologies are mainly reflected in several aspects, significantly restricting the efficiency and cost-effectiveness of underwater exploration. Due to their single function, multiple independent sealed chambers must be deployed simultaneously to meet the needs of full-band exploration. This not only occupies valuable mounting space on the vehicle but also increases the load burden on the submersible due to the weight of the equipment, affecting maneuverability and endurance. The structural design of the sealed chambers has shortcomings in pressure resistance and heat dissipation. For example, the sealing mechanism relies on simple annular grooves and rubber rings, which are prone to leakage under high pressure. The multi-stage heat dissipation process has low efficiency, and heat cannot be effectively transferred to the external seawater, resulting in large internal temperature fluctuations and potentially causing equipment overheating failures. In addition, poor versatility leads to low equipment reuse rate. Most sealed chambers are only suitable for specific underwater environments and cannot be applied across scenarios, driving up the overall cost. The weight and space occupation problems are further aggravated. The insufficient compactness and buoyancy design of the sealed chambers limit their adaptability in small vehicles or complex deployments, ultimately leading to resource waste and increased maintenance requirements. To address these issues, we propose an underwater multi-load constant-temperature sealed chamber device. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an underwater multi-load constant temperature sealed chamber device. This device achieves unified installation of multiple types of detection modules through integrated design, addressing the issues of traditional solutions that occupy multiple mounting positions and impose heavy loads on the submersible due to their single function. It effectively improves heat dissipation efficiency through a five-stage heat conduction mechanism and a mesh-rib thermal bridge structure, resolving temperature fluctuations and overheating failures caused by passive heat dissipation. A trapezoidal stop and a sealing rubber ring form a double sealing interface, enhancing waterproof reliability under high pressure and reducing leakage risks. Simultaneously, a standardized installation surface design improves the device's versatility and reduces deployment costs across multiple scenarios, effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an underwater multi-load constant temperature sealing chamber device, comprising a cylindrical sealing chamber body and a heat-conducting component;

[0006] The cylindrical sealed chamber body has two corresponding sealing cover assemblies installed on the left and right sides, and a detection component is installed on the left end of the left sealing cover assembly;

[0007] The heat-conducting assembly comprises hexagonal reinforcing support frames, heat-conducting mounting plates, T-shaped connecting blocks, and detection module bodies. Three hexagonal reinforcing support frames are equidistantly distributed along the axial direction of the cylindrical sealed chamber body. Six corresponding heat-conducting mounting plates are snapped onto the surfaces of the three hexagonal reinforcing support frames. Two corresponding T-shaped connecting blocks are positioned between adjacent heat-conducting mounting plates, and each T-shaped connecting block is connected to one of the heat-conducting mounting plates by bolts. All T-shaped connecting blocks are fixed inside the cylindrical sealed chamber body by bolts. Detection module bodies are evenly distributed on the sides of the heat-conducting mounting plates. The cylindrical sealed chamber body and the heat-conducting assembly provide a unified installation space for the detection module bodies, reducing the space occupied by mounting devices, while ensuring that heat is conducted from the detection module bodies to the external seawater, preventing excessively high temperatures from affecting equipment operation.

[0008] Furthermore, the sealing cover assembly includes a sealing cover, a sealing rubber ring, a first connecting hole, and a second connecting hole. Two sealing covers are provided, each snapped into the left and right ends of the cylindrical sealing chamber body. An annular groove is provided on the end face of each sealing cover, and a sealing rubber ring is snapped into the interior of the annular groove. The edge of the sealing cover has evenly distributed first connecting holes, and the left and right ends of the cylindrical sealing chamber body have evenly distributed second connecting holes. The first and second connecting holes correspond to each other. Through the design of the sealing cover, rubber ring, first connecting holes, and second connecting holes, the cylindrical sealing chamber body is sealed, making it suitable for underwater high-pressure environments. During installation, the corresponding first and second connecting holes are connected by bolts.

[0009] Furthermore, the detection component includes an observation port, waterproof glass, and a waterproof glass retaining ring. The observation port is provided at the left end of the left sealing cover, and the waterproof glass is fixed at the right end of the left sealing cover by the waterproof glass retaining ring. The waterproof glass and the observation port correspond to each other. Through the observation port and the waterproof glass, a viewing window is provided for the internal experimental equipment of the cylindrical sealed chamber body, avoiding frequent opening of the cover.

[0010] Furthermore, the inner wall of the cylindrical sealed chamber body is provided with a mesh rib extending to the outer wall. The mesh rib is 15mm thick and forms a thermal bridge with the contact area with the heat-conducting mounting plate. The mesh rib acts as a thermal bridge, promoting the conduction of heat from the heat-conducting mounting plate to the outer wall of the chamber.

[0011] Furthermore, the hexagonal reinforcing support frame has a thickness of 20mm, and the shell thickness of the cylindrical sealing chamber body is 12mm. By setting the hexagonal reinforcing support frame to resist water pressure deformation, the stability of the equipment in deep water operation is ensured, and maintenance needs are reduced. At the same time, the auxiliary heat-conducting mounting plate contacts the inner wall of the cylindrical sealing chamber body to improve the heat dissipation effect.

[0012] Furthermore, six heat-conducting mounting plates are evenly distributed around the circumference of the cylindrical sealed chamber body. The sides of the six heat-conducting mounting plates are provided with twelve independent mounting surfaces. The effective mounting dimensions of the mounting surfaces are 0.16m × 0.2m. By setting twelve independent mounting surfaces, the mounting of different band detection module bodies can be supported.

[0013] Furthermore, the combined structure of the cylindrical sealed chamber body, the hexagonal reinforcing support frame, and the heat-conducting mounting plate has a maximum deformation of no more than 0.1 mm under a water pressure of 6 MPa.

[0014] Furthermore, a trapezoidal stop structure is provided at the connection between the sealing cover and the cylindrical sealing chamber body. The sealing rubber ring is embedded in the trapezoidal stop to form a double sealing interface. The trapezoidal stop and the sealing rubber ring combine to create a double sealing barrier, which greatly reduces the risk of water leakage under high pressure environment such as 6MPa. At the same time, it simplifies the installation process and improves the durability of the equipment.

[0015] Furthermore, the cylindrical sealed chamber body has a diameter of 0.43m and a length of 0.65m. Its compact size makes it easy to mount on an underwater robotic arm or suspension frame, while reducing its own weight, providing a maximum buoyancy of 3800N, reducing the load on the submersible, and improving the portability and deployment efficiency of the equipment.

[0016] Furthermore, the waterproof glass has a thickness of not less than 15mm. Waterproof glass with a thickness of not less than 15mm provides sufficient pressure resistance to prevent damage from the underwater environment. Combined with the waterproof glass pressure ring, it enhances the sealing performance and supports long-term underwater use; reduces the failure rate and improves the reliability of the equipment.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This underwater multi-load constant temperature sealed chamber device has the following advantages:

[0018] 1. This underwater multi-load constant-temperature sealed chamber equipment achieves compact integration of multiple types of detection modules through an innovative hexagonal support frame and heat-conducting mounting plate layout, significantly reducing the space occupied by mounted equipment in underwater exploration missions. This design allows for flexible adaptation of general-purpose detection equipment with different wavebands or functions within a single sealed chamber, solving the problem of traditional solutions requiring the deployment of multiple independent chambers due to their single function. This significantly improves scientific research efficiency, reduces overall costs, and enhances equipment reusability, making it suitable for various underwater environments.

[0019] 2. The equipment employs a five-stage heat transfer mechanism, combined with a heat-conducting mounting plate, reinforced support frame, and mesh rib structure, forming a highly efficient thermal bridge system. This ensures that internal heat is rapidly transferred from the detection module body to the external seawater environment. This process avoids the shortcomings of traditional passive heat dissipation, effectively suppresses temperature fluctuations, maintains constant temperature conditions inside the chamber, and prevents performance degradation or malfunctions caused by overheating. Its heat dissipation process, through multi-stage optimization of thermal resistance, convection, and radiation, ensures the reliability of heat transfer and improves the long-term operational stability of the equipment in deep-water, high-pressure environments.

[0020] 3. The sealing cap assembly adopts a trapezoidal stop structure and a waterproof sealing ring design, creating a double sealing interface that greatly improves the equipment's waterproof and pressure-resistant capabilities and reduces the risk of leakage under high-pressure environments. The combined design of the cylindrical body and reinforced support frame enhances the overall structural rigidity, effectively resisting deformation caused by deep-water pressure and ensuring the equipment's durability under extreme conditions. Furthermore, the integrated design of the observation port and waterproof glass provides a viewing window for internal experiments, reducing frequent cap opening operations and further enhancing the equipment's maintenance convenience and operational safety.

The diameter of the cylindrical sealed chamber body 1 is 0.43m and the length is 0.65m. The compact size makes it easy to mount on an underwater robotic arm or suspension frame, while reducing its own weight, providing a maximum buoyancy of 3800N, reducing the load on the submersible, improving the portability and deployment efficiency of the equipment.

By setting twelve independent mounting surfaces, it is possible to support the mounting of different band detection module bodies 24. By setting hexagonal reinforced support frame 21, it is possible to resist water pressure deformation and ensure the stability of the equipment in deep water operation, reducing maintenance requirements. At the same time, the auxiliary heat-conducting mounting plates 22 contact the inner wall of the cylindrical sealed chamber main body 1 to improve the heat dissipation effect. Through the cylindrical sealed chamber main body 1 and the heat-conducting components 2, a unified installation space is provided for the detection module body 24, reducing the occupation of mounting positions. At the same time, it can ensure that heat is conducted from the detection module body 24 to the external seawater, preventing the temperature from being too high and affecting the operation of the equipment.

[0033] The sealing cap assembly 3 includes a sealing cap 31, a sealing rubber ring 32, a first connecting hole 33, and a second connecting hole 34. Two sealing caps 31 are provided, each snapped into the left and right ends of the cylindrical sealing chamber body 1.

The connection of the cylindrical sealing chamber body 1 is provided with a trapezoidal stop structure. The sealing rubber ring 32 is embedded in the trapezoidal stop to form a double sealing interface. The trapezoidal stop and the sealing rubber ring 42 are combined to create a double sealing barrier, which greatly reduces the risk of water leakage under high pressure environment such as 6MPa. At the same time, it simplifies the installation process and improves the durability of the equipment. Through the design of the sealing cover 31, rubber ring 32, first connecting hole 33 and second connecting hole 34, the sealing of the cylindrical sealing chamber body 1 is achieved. It is suitable for underwater high pressure environment. During installation, the corresponding first connecting hole 33 and second connecting hole 34 are connected by bolts.

Combined with the waterproof glass retaining ring, it enhances the sealing performance and supports long-term underwater use; reduces the failure rate and improves the reliability of the equipment. Through the observation port 41 and the waterproof glass 42, a viewing window is provided for the internal experimental equipment of the cylindrical sealed chamber body 1, avoiding frequent opening of the cover.

[0035] The combined structure of the cylindrical sealed chamber body 1, the hexagonal reinforcing support frame 21, and the heat-conducting mounting plate 22 has a maximum deformation of no more than 0.1 mm under a water pressure of 6 MPa.

[0036] The heat dissipation process of this invention includes a five-stage heat transfer mechanism: Step 1: The heating element is turned on and operates, converting electrical energy into heat energy, causing the element to heat up; it is known that the heating element is mainly an electrical appliance, and in the circuit consumption, heat energy accounts for approximately 80% to 95% of electrical energy. Taking the maximum value here, we can obtain:

[0037] φ1=95%*Q

[0038] Step 2: In accordance with the second law of thermodynamics, the heat of the component is partially transferred to the heat-conducting mounting plate through contact heat transfer, air convection heat transfer, and its own thermal radiation, resulting in first-order heat transfer.

[0039] I. Contact thermal resistance and heat transfer between components and thermally conductive mounting plate

[0054] φ2=φ 热阻2 +φ 对流2 +φ 辐射2

[0055] Step 3: In accordance with the second law of thermodynamics, the heat from the mounting plate is partially transferred to the inner wall of the sealed chamber through contact heat transfer and air convection heat transfer, resulting in secondary heat transfer;

[0069] Step 5: The sealed outer shell conducts heat to the surrounding seawater. This completes the heat conduction and cooling process.

[0070] The working environment is mainly at a depth of 300 meters or more in the ocean. This environment can be approximated as a constant temperature environment. Therefore, due to the temperature difference, the final heat transfer occurs between the outer shell of the working chamber and the seawater.

[0071] The final heat transfer is forced convection heat transfer from the sealed chamber shell to the seawater.

[0077] After substituting the collected test data for comparison, we can obtain:

[0078] φ 最终 >φ4>φ3>φ2>φ1

[0079] This ensures efficient heat dissipation.

[0080] The working principle of the underwater multi-load constant temperature sealing chamber device provided by this invention is as follows: The cylindrical sealing chamber body 1 is completely sealed by the sealing cover assemblies 3 on the left and right sides. The sealing cover 31 adopts a trapezoidal stop structure and embeds a sealing rubber ring 32 to form a double sealing interface to resist the high pressure environment of deep water. The detection component 4 integrated in the left sealing cover assembly 3 provides an internal viewing window through the observation port 41 and the waterproof glass 42 with a thickness ≥15mm. Its heat conduction process includes a five-stage heat transfer mechanism: the heat generated by the heating element is first transferred to the heat-conducting mounting plate 22 through contact heat transfer, air convection and heat radiation. Then, the heat continues to be conducted through the contact heat transfer, convection and radiation between the heat-conducting mounting plate 22 and the inner wall of the cylindrical sealing chamber body 1. Finally, the heat is transferred through the heat-conducting thermal bridge formed by the 15mm thick mesh ribs on the inner wall. Heat is conducted from the inner wall to the outer wall, and finally from the outer shell to the external seawater through forced convection. This process ensures that the heat dissipation efficiency meets the progressive relationship of φ_final>φ_4>φ_3>φ_2>φ_1. The structural strength is jointly guaranteed by three axially equidistant 20mm thick hexagonal reinforcing support frames 21 and 12mm thick cylindrical sealed chamber body 1. Under 6MPa water pressure, the maximum deformation is ≤0.1mm. The hexagonal reinforcing support frames 21 also assist the heat-conducting mounting plates 22 to make close contact with the inner wall to improve heat conduction efficiency. The six circumferentially evenly distributed heat-conducting mounting plates 22 are fixed by T-shaped connecting blocks 23 to form twelve independent mounting surfaces of 0.16m×0.2m, which support the flexible mounting of the multi-band detection module body 24 and realize the core function of a single sealed chamber accommodating multiple loads.
