Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of measuring engineering equipment, especially relates to a underwater topographic surveying instrument fixing support device. BACKGROUND

[0002] Underwater topographic survey is a specific survey of the horizontal position and elevation of underwater points of rivers, lakes, reservoirs, harbors and near sea in engineering survey. At present, single-beam and multi-beam underwater topographic survey both belong to the detection type of sonar. The single-beam survey principle is to vertically downward emit sound waves by transducer, when the sound waves meet the water bottom, reflection occurs, and the reflected echo signal returns to the transducer position and is received. The water depth value is determined by the double-way time of sound wave propagation in water and the average sound speed in water. The composition of single-beam depth sounder is relatively simple, mainly composed of single-beam depth sounder, GNSS positioning system, control, acquisition software and processing software and other hardware and software. The multi-beam survey principle is to emit wide sector coverage sound waves to the sea bottom by using the transducer array, to receive the sound waves by using the receiving transducer array, to form the illumination footprint of the sea bottom terrain through the orthogonality of the emission and receiving sectors, and to give the water depth value of the hundreds or even more measured points of the sea bottom in the vertical plane perpendicular to the heading through the appropriate processing of these footprints, so as to accurately and quickly measure the size, shape and height variation of the underwater target within a certain width along the route, and to more reliably depict the three-dimensional features of the sea bottom terrain. Combined with the navigation positioning and attitude data collected on site, a high-precision and high-resolution digital result map is drawn. The technical requirements of multi-beam also determine that the multi-beam sounding system is a measurement system including a plurality of auxiliary sensors, which is mainly composed of multi-beam depth sounder, surface sound velocity meter, sound velocity profiler, attitude instrument, compass, tide gauge, display control software (sonar working control software), navigation acquisition software (recording sonar and auxiliary sensor data), post-processing software, power supply, acquisition computer and other tools and other hardware and software products.

[0003] The single-beam and multi-beam underwater topographic survey is composed of multiple elements, and the components need to be used with the fixing support.

The use of the fixing support can simplify the installation and disassembly process of the multi-beam measurement system, reduce the required manpower and time, and the traditional installation method needs the workers to stand outside the ship side, which has certain danger.
