Description

Technical Field

[0001] The utility model relates to the field of underwater topographic survey, in particular to a micro-touch type muddy water underwater topographic instrument. Background Art

[0002] A topographer is a device used to measure, record and map underwater topography. They usually work using sound wave technology (called sonar), which sends sound waves underwater and measures the time and strength of the sound waves bouncing back to determine the location and shape of underwater objects.

[0003] Underwater topographs can be used for many applications, including marine geology, deep sea exploration, underwater building structure inspection, port and waterway survey, underwater pipeline and cable layout, etc. Modern underwater topographs can provide high-resolution and high-precision topographic data, which can be used to make underwater maps and 3D models, as well as for scientific research and resource exploration.

[0004] The existing technology has the following shortcomings: In the field of oil exploration, in order to ensure the stable and safe operation of oil platforms, it is necessary to measure the topography of shallow sea areas in order to find the best location to build oil platforms. However, in some shallow sea areas, due to the influence of river estuaries or ocean currents, the mud on the seabed of the shallow sea areas will surge upward, resulting in a high mud content in the water bodies of the shallow sea areas.

[0005] Due to the high sensitivity of traditional underwater topographs using laser or ultrasonic technology, when the sediment content in the water body is too high, the sediment and impurities in the water body will have a huge impact on the measurement results. Therefore, underwater topographs using laser or ultrasonic technology can only be used in clear water or under specific sediment content conditions, and cannot be used to measure underwater topography with high sediment content.

[0006] In addition to underwater topographs that use laser or ultrasonic technology, there is also a micro-touch underwater topograph that can measure underwater topography for water bodies with high sand content. Its working principle is to drive the micro-touch sensor downward through a probe rod until it touches the bottom of the water, record the downward displacement value and convert it into topographic data. However, due to the limited length of the probe rod of traditional micro-touch underwater topographs, they can usually only be used in shallow waters or inland rivers with shallow water levels. When used for topographic measurement in shallow seas, since the detection body needs to be set on the water surface and the probe rod is limited in length, the traditional micro-touch underwater topograph cannot measure the topography of shallow seas well.

[0007] Therefore, it is necessary to design a micro-touch muddy water underwater topographic instrument. Utility Model Content

[0008] To this end, the utility model provides a micro-touch type muddy water underwater topograph, the underwater topograph of the utility model is hoisted on the bottom of the hull by a steel cable and the rope is extended to make the underwater topograph descend to a position close to the seabed, then the seabed is measured at a fixed point by a micro-touch measuring probe, and the position of the micro-touch measuring probe is adjusted horizontally by a transverse guide rail and a longitudinal guide rail, so that the micro-touch measuring probe repeatedly performs fixed-point measurement and records the seabed topography under the hull, so as to solve the problem that when the sediment content in the water body is too high, the underwater topograph using laser or ultrasonic technology cannot perform accurate measurement, and the conventional micro-touch underwater topograph has a limited probe rod length and can only be applied to shallow beaches or inland rivers with shallow water levels. When applied to topography measurement in shallow sea areas, since the detection body thereof needs to be set on the water surface and the probe rod length is limited, the conventional micro-touch underwater topograph cannot measure the topography of shallow sea areas well.
