Description

Technical Field

[0001] The utility model relates to the technical field of terrain and depth sounding equipment, in particular to a multi-beam depth sounding equipment for seabed terrain detection. Background Art

[0002] In the detection of seabed topography, multi-beam bathymetry has made a great contribution. Single-beam bathymetry is a technology that uses the propagation characteristics of sound waves in water to measure the depth of water bodies. Since it can only obtain data along the track at a time, both the work efficiency and the accuracy of the output results are not satisfactory. The multi-beam bathymetry technology developed on this basis can send out hundreds of beams at the same time. The wide coverage of the bathymetry strip greatly improves the detection efficiency. The overlap rate between adjacent bathymetry strips can also provide more information for the seabed topography and improve the detection accuracy. Therefore, in the future, the application of multi-beam bathymetry technology will be more extensive.

[0003] In the prior art, multi-beam depth sounders are generally installed on the bottom of a ship when in use. However, during the voyage of the ship, the conditions under the sea are complex and unpredictable, so the extended multi-beam depth sounder is easily hit by corals, rocks or even fish, causing damage. This not only causes economic losses, but also requires the ship to return, which seriously affects the progress of scientific exploration. In addition, there are many shellfish that like to attach to the sea, so when the multi-beam depth sounder is used, it needs to be cleaned to ensure the detection effect. Utility Model Content

It should be noted that in the embodiment of the utility model, through the setting of the lifting component 2, when the multi-beam echo sounder 1 is used, the cylinder 202 is started to drive the telescopic shaft 203 to extend the multi-beam echo sounder 1 out of the installation box 201 for use. After use, the multi-beam echo sounder 1 is retracted through the cylinder 202, so as to avoid the problem that the multi-beam echo sounder 1 is exposed to the bottom of the ship for a long time and is damaged by objects such as corals, stones or fish, thereby ensuring the safe use of the multi-beam echo sounder 1;

[0045] The working principle of a multi-beam bathymetric device for seabed topography detection provided by the embodiment of the utility model is:

[0046] When the multi-beam echo sounder 1 is used, the cylinder 202 is started to drive the telescopic shaft 203 to extend the multi-beam echo sounder 1 out of the installation box 201 for use. After use, the multi-beam echo sounder 1 is retracted through the cylinder 202, thereby preventing the multi-beam echo sounder 1 from being exposed to the bottom of the ship for a long time and being damaged by objects such as corals, stones or fish, thereby ensuring the safe use of the multi-beam echo sounder 1.

[0047] Furthermore, the driving motor 408 is started to drive the driving column 404 to rotate, and the two transfer rods 405 are squeezed to move through the two extrusion grooves 407, so that the transfer rod 405 drives the moving slide bar 302 to move through the sliding block 402. At the same time, when the driving column 404 rotates one circle, the transfer rod 405 drives the moving slide bar 302 to move back and forth once, so that the bottom side of the multi-beam echo sounder 1 can be fully cleaned.
