The positions of the multiple sets of the first connecting hole 203 and the second connecting hole 207 are aligned one by one. The first connecting hole 203 and the second connecting hole 207 form a semi-circular arc channel. Through the setting of the first connecting hole 203 and the second connecting hole 207, during the use of the device, as the hull moves, the device needs to withstand a large pressure from the movement. Through the channel formed by the first connecting hole 203 and the second connecting hole 207, the pressure can be slowly guided and the internal and external pressure difference can be balanced, ensuring that the combined mechanism 2 is in a relatively stable pressure state, thereby ensuring the normal operation of the internal components.

The sealing rings 205 are located on the outside of the battery pack 211. Through the setting of the sealing rings 205, the sealing rings 205 are located on the mating surface between the top plate 201 and the mounting shell 206. As the main sealing structure, they effectively prevent external seawater from entering the equipment. Especially in the deep-sea high-pressure environment, seawater infiltration will seriously affect the safe operation of the battery pack 211 and the sensor 212. The sealing rings 205 form an effective barrier through tight fit and compression, ensuring the long-term stable operation of the equipment.

[0027] Furthermore, five sets of partition slots 210 are provided, and the five sets of partition slots 210 are evenly distributed on the mounting shell 206. Through the setting of partition slots 210, the partition slots 210 serve as the fitting mounting positions for sensors 212, allowing multiple sensors of different models to be embedded in their respective slots, achieving physical separation and fixation. This structure can prevent the sensors 212 from being displaced, loosened, or damaged due to equipment vibration or water flow impact, thereby improving the overall working stability and durability of the equipment.

[0028] Furthermore, the sensor 212 is electrically connected to the battery pack 211. The sensor 212 comes in various models. Through the arrangement of the sensor 212, it can include various types (such as temperature sensors, pressure sensors, magnetic field sensors, vibration sensors, humidity sensors, etc.). By deploying at multiple points and varying the models, it is possible to monitor the seabed environment around the pipeline in multiple dimensions, enabling the profiler to have a comprehensive understanding of the working status of the natural gas pipeline and its surrounding environment. At the same time, the sensor 212 is set in an independent partition slot 210, which facilitates the arrangement or replacement of different models of sensor 212 as needed. It can also expand new monitoring functions according to the usage scenario (such as corrosion sensors, pH value sensors, etc.), and has a high degree of modularity and customization capability to adapt to the needs of different types of pipelines and marine environments.

[0029] Working Principle: This profiler achieves a high degree of integration of various functions through the tight connection between the mounting head 1 and the assembly mechanism 2. The mounting head 1 serves as the basic structure for connecting the device to the hull. The assembly mechanism 2 is set on one side of its surface. The assembly mechanism 2 consists of an upper and lower cavity structure formed by the top plate 201 and the mounting shell 206, and is reliably fixed by four sets of bolts 204. At the same time, the sealing rings 205 are installed on the outside of the battery pack 211 in progressively increasing order, effectively improving the waterproof and pressure-resistant capabilities of the structure. Multiple sets of connecting holes can ensure the stability of the device during movement. Finally, the sensor 212 is electrically connected to the battery pack 211, and power supply and data transmission are achieved through internal wires or circuit boards. The data collected by the sensor 212 can be transmitted to the main control system in real time to realize the acquisition function of multiple types and dimensions of signals, such as temperature, pressure, magnetic field, vibration, etc.
