[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0026] like Figures 1 to 4 As shown, this utility model provides a technical solution: a high-stability magnetometer array mounting structure for underwater magnetic field target detection, including an underwater platform carrier mounting base 1, an underwater platform carrier mounting base 1 connected to a middle frame 3 via a connector 2, a magnetic shielding plate 4 provided on the connector 2 between the connector 2 and the middle frame 3, the middle frame 3 including a frame body 31, mounting holes 32 are provided on both short sides of the frame body 31, a slide rail 6 is connected to the mounting holes 32 via a connecting bolt 5, a slide rail 6 is connected to the middle of one side of the frame body 31 where the mounting holes 32 are located via a connecting bolt 5, a connector 7 is installed on the slide rail 6, and the connector 7 is connected to the magnetometer probe;
[0027] The connector 2 includes a threaded post 21 fixed on the frame 31. A threaded connector 23 is threadedly connected to the end of the threaded post 21 away from the frame 31. A rotary connector 24 is connected to the end of the threaded connector 23 away from the threaded post 21. The rotary connector 24 is rotatably installed in the rotary seat 25. A spring 26 is provided on the rotary connector 24 between the threaded connector 23 and the rotary seat 25. The two ends of the spring 26 abut against the threaded connector 23 and the rotary seat 25 respectively. The depth of the rotary seat 25 is greater than the thickness of the rotary table of the rotary connector 24. A washer 27 is embedded in the end of the rotary seat 25 away from the threaded connector 23. A spring piece 28 is embedded in one side of the rotary seat 25 where the washer 27 is located. A clamp 29 is bolted to the rotary seat 25 at both ends of the washer 27.
[0028] Furthermore, a nut 22 is threadedly connected to the threaded post 21, and the magnetic shielding plate 4 is installed on the threaded post 21 between the frame 31 and the nut 22;
[0029] Furthermore, the underwater platform carrier mounting base 1 is placed between the gasket 27 and the clamp 29.
[0030] In this embodiment, the underwater platform carrier mounting base 1 and the middle frame 3 are dynamically buffered and magnetically shielded by connector 2. At the same time, the slide rail 6 is fixed by connecting bolt 5 through the mounting hole 32 on the frame 31 of the middle frame 3, and connector 7 is deployed on the slide rail 6 to connect the magnetometer probe, thereby improving the stability of underwater magnetic field detection.
[0031] Specifically, the threaded post 21 of connector 2 is fixed to the frame 31, and the nut 22 is threadedly connected to the threaded post 21. The magnetic shielding plate 4 is installed on the threaded post 21 between the frame 31 and the nut 22. This design can directly shield magnetic field interference from above and reduce the noise impact on the magnetometer. At the same time, the threaded joint 23 connects the nut 22 and the rotating joint 24. The rotating joint 24 is rotatably installed in the rotating seat 25. The depth of the rotating seat 25 is greater than the thickness of the rotating table of the rotating joint 24 to provide rotation clearance. The two ends of the spring 26 abut against the threaded joint 23 and the rotating seat 25 respectively to form an elastic buffer to absorb underwater impact and vibration. The end of the rotating seat 25 away from the threaded joint 23 is embedded with a washer 27 and a spring clip 28. The two ends of the washer 27 are bolted to the rotating seat 25. The underwater platform carrier mounting seat 1 is placed between the washer 27 and the spring clip 29. Stable fixation is achieved through the clamping action of the spring clip 28 and the spring clip 29, and slight displacement compensation is allowed. Example
[0032] like Figure 2 and Figure 4As shown, connector 2 7 includes a rotary joint 2 71 that is slidably installed in the guide groove of slide rail frame 6. Rotary joint 2 71 is connected to magnetometer connector 73 through connector bolt 2 72. A rubber pad 74 is provided between magnetometer connector 73 and connector bolt 2 72.
[0033] Among them, the magnetometer connector 73 is connected to the magnetometer probe.
[0034] In this embodiment, the second rotary joint 71 is slidably installed in the guide groove of the slide rail frame 6, so that the magnetometer probe can move freely in the slide rail direction to adjust its position. The second rotary joint 71 is connected to the magnetometer connector 73 through the second connecting bolt 72. A rubber pad 74 is provided between the magnetometer connector 73 and the second connecting bolt 72 to provide elastic buffering. The magnetometer connector 73 is directly connected to the magnetometer probe to ensure physical fixation and signal transmission.
[0035] Working principle:
[0036] like Figures 1 to 4 As shown, the present invention utilizes the structural design of connector 2, in which the magnetic shielding plate 4 installed on the threaded post 21 can effectively isolate the stray magnetic field generated by the underwater platform carrier, significantly reducing electromagnetic interference to the magnetometer probe. Furthermore, the cooperation between the rotating joint 24 and the rotating seat 25 of connector 2 provides rotational freedom. The springs 26, which abut against the threaded joint 23 and the rotating seat 25 respectively, form a buffer, effectively absorbing the impact and vibration caused by underwater turbulence or carrier movement. The underwater platform carrier mounting seat 1 is clamped between the gasket 27 with embedded spring piece 28 and the bolt-connected sleeve 29. The elastic deformation of the spring piece 28 compensates for the installation stress, avoiding structural damage caused by rigid connection. The rotating joint 71 of connector 2 is slidably installed in the guide groove of the slide rail frame 6, allowing the magnetometer probe to be finely adjusted along the slide rail to adapt to the detection requirements. At the same time, the magnetometer connector 73 is connected to the rotating joint 71 through the connecting bolt 572. The rubber pad 74 set in between further attenuates high-frequency mechanical vibration, ensuring the stability of the magnetometer probe measurement environment.
[0037] The overall structure of this utility model achieves modular assembly through threaded and bolted connections, which facilitates underwater maintenance or component replacement, and ultimately greatly improves the accuracy, reliability and service life of magnetic field target detection in complex underwater environments.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
