[0002] In fields such as ocean exploration and underwater engineering, dual-frequency identification sonar, as an important detection device, is widely used in underwater topographic mapping, target detection, and identification. The installation method and adjustment functions of sonar equipment have a crucial impact on its detection effectiveness. Proper installation and flexible adjustment ensure that sonar can obtain more comprehensive and accurate data.

[0003] Traditional dual-frequency sonar shipboard mounting devices have many shortcomings. In terms of the stability of dual-frequency sonar installation, most devices use a simple fixing method and lack a reliable clamping structure.

The first worm 4 is meshed with a first worm gear 6. The self-locking property of the first worm 4 and the first worm gear 6 ensures a constant clamping force and a good clamping effect. A screw rod 7 is penetrated by the first worm gear 6 and is coaxially fixedly connected thereto. The screw rod 7 penetrates the dual-frequency sonar 1 and the protective cover 3 and is rotatably connected thereto. The outer wall of the screw rod 7 is sleeved with two sliders 9 threadedly connected thereto. The screw rod 7 is provided with two sections of external threads with opposite thread directions. The two sliders 9 are respectively mounted on the outer walls of the two sections of external threads with opposite thread directions. The screw rod 7 drives the two sliders 9 to move relative or opposite to each other through thread transmission. The inner wall of the mounting plate 2 is fixedly connected to two sliding rods 8. The two sliding rods 8 pass through each slider 9 and are slidably connected thereto. The sliding rods 8 guide the movement of the sliders 9. The bottoms of the two sliders 9 are fixedly connected with plywood 10. The two plywood 10 are located on both sides of the dual-frequency sonar 1 and are set against the outer wall of the dual-frequency sonar 1.

A first adjustment mechanism is provided on the hollow column 12, and the first adjustment mechanism includes a second worm 13 that passes through the hollow column 12 and is rotatably connected thereto. The end of the second worm 13 away from the hollow column 12 is fixedly connected to a second handle 14, and the second worm 13 is meshed with a second worm gear 15. The second worm 13 and the second worm gear 15 cooperate to realize the transmission of power and the conversion of motion forms. A threaded rod 16 is passed through the second worm gear 15 and is coaxially fixedly connected thereto. The top of the threaded rod 16 is rotatably connected to the hollow column 12, and the threaded rod 16 is threadedly connected to the column 11.

The lower U-shaped frame 18 is fixedly connected to a connecting frame 20, and the end of the connecting frame 20 is fixedly connected to the side wall of the rotating plate 19. The upper U-shaped frame 18 is fixedly connected to a hydraulic rod 21, and the hydraulic rod 21 is rotatably connected to the side wall of the rotating plate 19. The hydraulic rod 21 drives the upper U-shaped frame 18 to rotate by telescoping, thereby driving the hollow column 12 to rotate, thereby realizing the angle adjustment of the dual-frequency sonar 1.

A third adjustment mechanism is provided on the ship's side C-shaped plate 23. The third adjustment mechanism includes a fixed plate 24 fixedly connected to the upper rotating shaft 22. A plurality of through holes 25 are opened on the fixed plate 24. The fixed plate 24 cooperates with the rotating shaft 22 to provide multiple swing angle adjustments for the dual-frequency sonar 1. In a fixed position, two plug rods 27 are provided on the C-shaped plate 23 on the side of the ship and are slidably connected to it. The steering angle of the dual-frequency sonar 1 can be adjusted by pulling out the plug rods 27. The two plug rods 27 are fixedly connected to the connecting plate 26.

The rotating plate 19 can be rotated to rotate it with the rotating shaft 22 as the rotation center, and the swing angle of the dual-frequency sonar 1 can be adjusted to meet different usage needs. After a long period of detection, the staff can hold the first handle 5 and rotate it to drive the first worm 4, the first worm wheel 6, and the screw 7 to rotate, so that the sliders 9 and the splints 10 on both sides move back to each other, and the dual-frequency sonar 1 can be removed for maintenance. After the maintenance is completed, the dual-frequency sonar 1 is placed between the two splints 10, and the first handle 5 is held and rotated in the opposite direction to move the splints 10 on both sides relative to each other until the two splints 10 are against the outer walls of the two ends of the dual-frequency sonar 1, thereby completing the clamping and fixation of the dual-frequency sonar 1 and ensuring that the dual-frequency sonar 1 is firmly installed.
