[0022] Example: Reference Figure 1-4 The device shown is a device for simulating water ingress into a damaged underwater closed cabin, comprising a high-pressure water storage tank 2 for storing water entering the closed cabin.

[0023] Modular cabin 3 is used to simulate the damage and flooding scenario.

[0024] The water outlet pipe 4 is connected to the water outlet end of the high-pressure water storage tank 2, and the other end of the water outlet pipe 4 is connected to a variable-caliber adjustment disk 9. The water outlet end of the variable-caliber adjustment disk 9 is provided with a nozzle. The water outlet end of the variable-caliber adjustment disk 9 passes into the interior of the modular cabin 3. The nozzle of the variable-caliber adjustment disk 9 is externally slidably sleeved with a sliding ring 8. An electric push rod 7 is fixedly installed on the variable-caliber adjustment disk 9. The output end of the electric push rod 7 drives the sliding ring 8. The nozzle of the variable-caliber adjustment disk 9 is hingedly connected to a plurality of nozzle blades 11 that enclose a nozzle. The outer side of the nozzle blade 11 is hingedly connected to a connecting rod 10. The other end of the connecting rod 10 is fixedly connected to the sliding ring 8.

[0025] The data acquisition system 16 integrates pressure, flow and temperature sensors inside the modular cabin to collect changes in environmental parameters inside the modular cabin.

[0026] A multi-scenario breach simulation module includes a breach panel 17 .

[0027] For example, the underwater closed cabin is connected to a high-pressure water tank, and the high-pressure water tank can adjust the pressure to simulate the underwater depth; the diameter of the water inlet of the underwater closed cabin can be adjusted to simulate the degree of damage to the closed cabin; the combination of the two can simulate the water inflow situation of the closed cabin at different underwater depths and different damage diameters.

[0028] With the above structure, the data acquisition system 16 transmits the data to the terminal through the wireless module so that the terminal personnel can analyze and view the data.

[0029] For example, the wireless module in this device primarily serves as a data transmission bridge. Its core function is to transmit real-time environmental parameters collected by sensors such as pressure, flow, and temperature in the data acquisition system 16 to terminal devices (such as computers and tablets) via wireless communication protocols, enabling remote data reception, storage, and analysis. Considering the signal transmission requirements of underwater sealed cabins (anti-interference, low power consumption, and medium bandwidth), ZigBee or LoRa modules are preferred. If real-time high-definition data (such as video surveillance) is required, a WiFi module can be used in conjunction. The wireless module is a core component for achieving "intelligent monitoring" in this device. Its value lies not only in replacing traditional cables, but also in its flexible transmission, real-time response, and high reliability, which enhances the accuracy and safety of underwater sealed cabin damage and flooding experiments, providing efficient data support for research such as cabin structural design and waterproofing plan optimization. The wireless module offers flexible installation and layout, adapting to the modular design, eliminating the need for complex cabling and preventing cable entanglement that can hinder the assembly and disassembly of the modular cabin. It is particularly suitable for the rapid replacement of breach panels in multi-scenario breach simulation modules. Using wireless modules for data transmission improves system reliability and security, reduces the risk of cable damage, and enhances the device's waterproof performance. Wireless data can be transmitted simultaneously to multiple terminals (such as laboratory consoles and remote expert computers), supporting simultaneous analysis by multiple people and improving scientific research efficiency. Wireless modules reduce the workload of cable maintenance and replacement and enable seamless integration into the Internet of Things (IoT) platform. Future sensor additions (such as water quality sensors and vibration sensors) can be achieved by simply adding nodes to the wireless network, eliminating the need for hardware modifications.

[0030] By means of the above structure: the breach panel 17 has preset cracks, circular holes and explosion hole structures, and is connected to the bulkhead of the modular cabin through a magnetic interface.

[0031] The breach panel's pre-set structure and magnetic interface design essentially improve experimental efficiency and data quality through "scenario modularization" and "intelligent connectivity." This design not only meets the need to simulate diverse damage forms in scientific research scenarios, but also addresses the complex structures and difficult maintenance challenges of traditional underwater experiments through features such as tool-free rapid replacement and highly leak-tight connections. This provides more flexible and precise technical support for cabin waterproofing research. For example, the crack structure can simulate irregular damage to the cabin caused by water pressure, impact, or material fatigue. The water inflow path is complex, and the flow rate changes dynamically with crack extension, making it suitable for studying the leakage characteristics of structural damage. The circular hole structure can simulate regular breaches such as punctures and pipe ruptures. The water inflow flow rate can be accurately calculated based on the hole diameter, facilitating the development of standardized flow-pressure mathematical models. The explosion hole structure can simulate sudden large breaches caused by explosive impact. The breach has irregular edges and may be accompanied by structural deformation, making it suitable for studying the impact effects of transient high-pressure water inflow on cabins. Through different structural combinations, a variety of real-life scenarios such as ship collisions, underwater explosions, and corrosion perforations can be reproduced, providing more comprehensive experimental data for cabin waterproofing design. The modular cabin can quickly reconstruct experimental scenarios, such as switching from a "small breach with a circular hole" to a "large breach with an explosion hole," to meet the efficient connection of multiple sets of consecutive experiments. The versatility of the magnetic interface allows the breach panel to be docked with the bulkhead at any position, simulating damage at different locations such as the cabin top, side walls, and bottom, expanding the experimental dimension. The magnetic interface can use neodymium iron boron permanent magnets, and the adsorption force can offset the thrust of the underwater pressure on the panel. Combined with the annular sealing ring on the bulkhead, it achieves IP68 waterproof sealing, preventing water leakage from interfering with data collection during the experiment. The magnetic force is evenly distributed around the panel, making it less likely to fail due to uneven local force than screw fixation.

[0032] With the above structure, the outlet pipe 4 and the variable-caliber adjustment disk 9 are detachably connected via a clamp 21, which has an inflatable sealing ring built into the clamp to seal the connection. Specifically, the clamp 21 is fixedly mounted on the outside of one end of the outlet pipe 4, and an inflatable sealing ring 22 is fixedly mounted on the inside of the clamp. One end of the variable-caliber adjustment disk 9 is provided with a connecting portion 25, and the outer wall of the connecting portion 25 is provided with a sealing groove 24. The inflatable sealing ring 22 and the sealing groove 24 are adapted to fit and seal.

[0033] The use of inflatable seals can facilitate quick sealing and subsequent disassembly and separation.

[0034] With the above structure, an air pressure sensor is provided inside the inflatable sealing ring 22 , and the inflatable sealing ring is connected to the inflation and deflation air pump 23 via a pipeline to facilitate adjustment of the sealing state of the inflatable sealing ring 22 .

[0035] With the above structure, the clamp 21, the water outlet pipe and the variable-caliber adjustment disk 9 are all detachably connected by bolts, which facilitates the disassembly and separation of the high-pressure water storage tank 2 and the modular cabin 3.

[0036] With the above structure: a drain outlet connected to the interior of the modular cabin 3 and equipped with a control valve is provided at the rear thereof for facilitating the discharge of experimental water, and the drain outlet can be sent to the high-pressure water storage tank 2 through a pipeline for recycling.

[0037] With the above structure, a water pump with an output end connected to the interior of the high-pressure water storage tank 2 is fixedly installed on the rear side of the high-pressure water storage tank 2 to facilitate the injection of water for the experiment.

[0038] By means of the above structure: the high-pressure water tank 2 is fixed on the base 1, the bottom end of the modular cabin 3 is fixedly installed with a slider 18, the top end of the base 1 is fixedly installed with a guide rail 19, the slider 18 and the guide rail 19 are slidably connected, and a handle 20 is fixedly installed on the slider 18. When separating the modular cabins, the modular cabins can be separated by pulling the handle by removing the clamp bolts at the variable-caliber adjustment disk.

[0039] The working principle of this embodiment is as follows: a device for simulating water ingress into a damaged underwater closed cabin, wherein the underwater closed cabin is connected to a high-pressure water storage tank, and the high-pressure water tank outlet pipe of the high-pressure water storage tank can adjust the water pressure entering the modular cabin by controlling the water outlet through an electrically controlled valve, and the water pressure is detected by a pressure sensor to simulate the underwater depth; the diameter of the water inlet of the underwater modular cabin can be adjusted, and by turning on the electric push rod, it drives the sliding ring to slide along the outer wall of its pipe, and the sliding ring pushes the nozzle blades at the nozzle to open or close to adjust the size of the nozzle, thereby simulating the degree of damage to the closed cabin; the combination of the two can simulate the water ingress of the closed cabin at different underwater depths and different damage diameters.

[0040] Through pressure-caliber dual-variable coupling control, intelligent monitoring and modular design, the water inlet pressure of the cabin is adjusted by a high-pressure water storage tank to simulate the underwater depth; the caliber of the water inlet of the underwater closed cabin is adjusted to simulate the degree of damage to the closed cabin; the two are combined to simulate the water inflow conditions of the closed cabin at different underwater depths and different damage calibers, realizing high-precision dynamic simulation of the underwater closed cabin under complex working conditions, and solving the problem of collaborative research on deep-water environment and damage scenarios.
