[0014] The following describes the embodiments with reference to the accompanying drawings to further illustrate the specific implementation of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, etc.

[0015] like Figure 1 As shown, the underwater hydraulic magnetic adsorption mechanism includes a cylinder 1, a hydraulic rod 2, a connecting structure, and a modified permanent magnet 3. The hydraulic rod 2 is set in the cylinder 1 and is pushed up and down by the cylinder 1. The two ends of the connecting structure are respectively connected to the top of the hydraulic rod 2 and the modified permanent magnet 3. The connecting structure includes a spherical cover plate 4 and a spherical cover plate 5. The spherical cover plate 4 is fixedly connected to the modified permanent magnet 3. One end of the spherical cover plate 5 is connected to the spherical cover plate 4, and the other end of the spherical cover plate 5 is connected to the hydraulic rod 2. The connection method between the spherical cover plate 4 and the spherical cover plate 5 is similar to a universal joint, and can be tilted within a certain angle.

[0016] like Figure 2 As shown, the modified permanent magnet 3 includes a permanent magnet 6, a switching cylinder 7, a rack 9 and a gear 8. The gear 8 is provided at one end of the permanent magnet 6, and the other end is movably connected to the side of the modified permanent magnet 3. The switching cylinder 7 is provided with a rack 9. The gear 8 on the permanent magnet 6 is stuck on the rack 9 of the switching cylinder 7. The switching cylinder 7 drives the rack 9, the rack 9 drives the gear 8 to rotate, and the gear 8 drives the permanent magnet 6 to rotate. There are two racks 9, and the two racks 9 are respectively provided on the surface of the switching cylinder 7. The two racks 9 are staggered and mesh with the gear 8.

[0017] like Figure 1As shown, this adsorption mechanism is typically used in multiple groups. The chamber is fixed to the flange of the oil cylinder 1. The modified permanent magnet 3 primarily functions to attract the dry welding chamber to the hull steel plate, providing adsorption force. The attraction force of the modified permanent magnet 3 can be adjusted as needed, typically exceeding 2 tons. A hydraulic structure controls the engagement and disengagement of the modified permanent magnet 3. By switching the oil cylinder 7 to drive the rotating permanent magnet 6, the permanent magnet rotates 90 degrees. During this 90-degree rotation, the device's magnetic force is either increased or decreased, thereby controlling the presence or absence of magnetic force.

[0018] This hydraulic magnetic attraction mechanism increases overall attraction force by utilizing multiple mechanisms operating simultaneously. Multiple mechanisms can also be arranged on different planes to accommodate uneven surfaces, providing robust engineering applications. The hydraulically controlled rotation of the magnets allows for adjustable pressure and speed, enabling optimal attraction force in various operating environments. The system utilizes a hydraulic control system, allowing operators to easily operate the handle from the control room. This single hydraulic magnetic attraction mechanism boasts a compact head mechanism with a simple structure, making it easy to replace and transport.

[0019] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
