Problems solved by technology

[0003] The existing multi-beam detection device is based on the manual hoist lifting instrument, which has obvious shortcomings and deficiencies: (1) The manual hoist lifting instrument has no pole fixing device, which makes the instrument prone to displacement in the longitudinal direction, thus affecting the quality of survey data; ( 2) It is difficult to accurately position the instrument support rod in the vertical direction; (3) There is no fixed guide rail on the well wall, which makes the scientific instrument easy to shake in the horizontal direction, which affects the quality of survey data; (4) Lack of dynamic draft and surface sound velocity measurement, Affects the accuracy of multi-beam detection; (5) Poor applicability and convenience. The retraction, installation and disassembly of the instrument requires joint operations by multiple people, which increases the difficulty and risk of investigation in the turbulent marine environment

Abstract

The invention discloses a multi-beam detection device and method based on worm gear lead screw lifting. The device comprises a vertical shaft, a stand, a thread lifting rod, a lift truck, a worm gear lead screw lifting machine, an instrument stand and an auxiliary instrument bin. A track is arranged on the inner wall of the vertical shaft, and the lift truck moves in the track through truckles; the worm gear lead screw lifting machine is fixedly arranged on the stand and is connected with the lift truck through the thread lifting rod; the instrument stand is connected with the thread lifting rod by a flange plate, a multi-beam energy transducer stand is arranged at the bottom of the instrument stand; the auxiliary instrument bin is arranged in the middle of the instrument stand, a pressure sensor and a surface-layer velocimeter are arranged in the auxiliary instrument bin and are used for measuring dynamic draft and surface-layer sound velocity. The multi-beam detection device and method are used for portably installing and detecting various models of intermediate-shallow water multi-beam detection systems. The multi-beam detection device and method can be widely applied to oceanographic survey, ocean hydrographic surveying and oceanographic engineering.

Description

technical field [0001] The invention belongs to the technical field of marine survey and seabed detection, and specifically refers to a multi-beam detection device and method based on the lifting and lowering of a worm gear screw. Background technique [0002] The multi-beam bathymetry system is currently the most advanced seabed bathymetry equipment, which is highly integrated with various sensors and has high requirements for instrument installation. Multi-beam probes need to be submerged in water for sound wave transmission and reception. The accuracy, stability and safety of multi-beam probe installation are important factors restricting multi-beam detection in shallow water. There are three ways to install the multi-beam probe: fixed installation on the bottom of the ship, portable installation on the side of the ship and installation in the shaft. Bottom installation is costly and difficult to disassemble and maintain. Portable installation on board will reduce surve...
