The horizontal plate 2 is fixedly connected to the outer wall of the mounting plate 1, and the sonar probe 3 is located below the horizontal plate 2. It also includes a lowering assembly and a direction adjustment assembly. The lowering assembly is located on the horizontal plate 2, and the direction adjustment assembly is located between the direction adjustment assembly and the sonar probe 3.

[0026] The depth of the sonar probe 3 in the ocean is adjusted by lowering the component, and the detection direction of the sonar probe 3 in the ocean is adjusted by directional adjustment component.

[0027] like Figures 1-5As shown, to address the issue of the sonar probe 3 being fixedly exposed on the outside of the ship's bottom plate, increasing the ship's drag during movement, the lowering assembly includes a top cylinder 4, a cylindrical cylinder 5, an adjusting rod 6, a worm gear 7, a worm wheel 8, a middle cylinder 9, a bottom cylinder 10, and a limiting rod 11. The top cylinder 4 is fixedly connected to the top of the horizontal plate 2. The cylindrical cylinder 5 is vertically and rotatably connected to the horizontal plate 2. The adjusting rod 6 is vertically and threadedly connected inside the cylindrical cylinder 5, with its upper end vertically penetrating the top cylinder 4 and slidingly connected to it. A servo motor 12 is fixedly installed on the top of the horizontal plate 2. The worm gear 7 is fixedly connected to the output end of the servo motor 12. The worm wheel 8 is fixedly connected to the cylindrical cylinder 5, and the worm gear 7 and worm wheel 8 mesh with each other.

The upper end of the limiting rod 11 vertically passes through the bottom of the middle cylinder 9 and slidesly connected to it.

[0028] like Figures 1-5 As shown, in order to solve the problem of inconvenience in adjusting the detection direction according to the needs of use, the direction adjustment component includes a bottom shaft 13, a bevel gear 14 and a bevel gear 15. The bottom shaft 13 passes vertically through the bottom of the bottom cylinder 10 and is rotatably connected to it. The sonar probe 3 is fixedly installed at the lower end of the bottom shaft 13.
