Three-dimensional positioning device for underwater high-pressure water dirt removing nozzle

Abstract

The invention discloses a three-dimensional positioning device for an underwater high-pressure water dirt removing nozzle which comprises a variable-length water gun, a high-pressure water nozzle fixed to the front end of a variable-length water gun barrel through a nozzle fast locking device and a high-pressure water inlet pipe connected to the rear end of the gun barrel, and further comprises an underwater sonar 3D positioning unit arranged on a gun body, wherein the gun barrel is fixed to the gun body through a water gun fast locking device. The underwater sonar 3D positioning unit comprises a sonar signal generator, a power amplifier, a sonar with one transmitting unit and three receiving units distributed along the circumference distributed at equal intervals, a signal amplifier, a distance recognition and correction module, a temperature and salinity measurement module and a warning device, all of which are in circuit connection. By means of three-dimensional positioning device for the underwater high-pressure water dirt removing nozzle, the positioning capability and the work efficiency of the underwater high-pressure dirt removing nozzle are greatly improved through a sonar 3D positioning manner, dirt removing energy consumption is reduced, the labor intensity is lowered, the problem that the work efficiency is low due to muddy water blind sight is effectively solved, and obvious advantages are achieved in the aspects of underwater dirt removing work efficiency and work accuracy.

Description

technical field [0001] The invention relates to a three-dimensional positioning device for an underwater high-pressure water cleaning nozzle, and belongs to the technical field of marine underwater operations. It adopts 3D sonar distance measurement, temperature and salt compensation, and the recognition technology of water mixing waveform caused by dirt when cleaning with a specific high-pressure water gun. In addition, it also requires high sealing, anti-corrosion and seawater pressure resistance. Background technique [0002] The demand for marine operations and offshore oil and gas mining is increasing, and a large number of ships, marine equipment and offshore oil and gas derricks are emerging. It cannot be ignored that the biofouling represented by sea oysters greatly reduces the performance of the equipment in different forms. As a countermeasure technology, the underwater high-pressure water cleaning technology, because the water environment hinders the diffusion of ...
