The automatic underwater landform detection device has a wide application prospect in the technical field of underwater landform measurement equipment.

Description

technical field [0001] The invention relates to an underwater terrain automatic detection device suitable for rapid current environment. The device adopts a semi-submersible design. During the process of drifting in the torrent, the DGPS (Difference Global Positioning System) system and the ultrasonic sounding system are used to detect the underwater terrain of the river, and the sensor is used to detect the conventional water quality indicators of the river. The utility model belongs to the technical field of underwater terrain surveying equipment. Background technique [0002] In order to guide the construction of water conservancy projects, the development of river and lake resources, flood control and disaster reduction, etc., underwater topographic survey and underwater topographic map drawing are necessary preparations before the implementation of various water projects. At present, there are many methods for underwater terrain measurement. The general principle is to...

AI Technical Summary

Problems solved by technology

Confined by design ideas and instrument limitations, most of the current underwater topographic measurement devices can only be used in rivers, lakes or reservoirs with gentle water flow and calm water surface. However, some special water conservancy project construction, resource development, flood control and disaster reduction, etc. The task needs to be carried out in the river section with turbulent water flow, which requires a new type of underwater terrain measurement device suitable for rapid current environment
