Description

Technical Field

[0001] This utility model relates to the field of underwater detection technology, and in particular to a multibeam bathymetry device. Background Technology

[0002] Multibeam echo sounders evolved from single-beam echo sounders, capable of simultaneously providing dozens or even hundreds of depth readings in a plane perpendicular to the course of the survey. They can accurately and rapidly determine the size and shape of underwater targets within a certain width along the course, thus reliably depicting the fine features of underwater topography and truly realizing surface measurement of underwater topography. Compared to single-beam echo sounders, multibeam echo sounders offer advantages such as a larger measurement range, higher speed, greater accuracy, and higher efficiency. However, existing multibeam echo sounders use screws to fix the receiving and transmitting transducers during installation, which is inconvenient for aligning the threaded holes and time-consuming. Furthermore, in nearshore surveying, the presence of obstacles such as fishing nets and floating buoys in the work area can easily affect multibeam echo sounding, potentially causing the probe to be scratched or damaging the equipment.

A fixed clamping plate 2-1, a first movable clamping plate 2-2, a second fixed clamping plate 2-6, and a second movable clamping plate 2-7 are provided. The first fixed clamping plate 2-1 and the second fixed clamping plate 2-6 are fixed to the lower surface of the mounting plate 2. The first movable clamping plate 2-2 and the second movable clamping plate 2-7 are movable relative to the first fixed clamping plate 2-1 and the second fixed clamping plate 2-6, respectively. Springs 2-4 that exert compressive force on the outer side of the first movable clamping plate 2-2 and the second movable clamping plate 2-7 are provided.

[0030] For example, the lower surface of the mounting plate 2 is provided with a first spring groove 2-3 and a second spring groove 2-8 to facilitate the installation of the spring 2-4. The first movable clamping plate 2-2 is slidably disposed in the first spring groove 2-3 and connected to the spring 2-4, and the second movable clamping plate 2-7 is slidably disposed in the second spring groove and connected to the spring 2-4.

[0031] For example, the mounting plate 2 has a wire hole 2-11 in the middle to facilitate the passage of wires.

The extension neck is slidably fitted into the annular groove 1-1. The upper and lower parts of the annular groove 1-1 are respectively provided with fixing holes 1-2, and the extension neck is provided with insertion holes 5-3 corresponding to the fixing holes 1-2.
