Underwater cavitation cleaning disc, device and system

Abstract

The invention belongs to the technical field of underwater cleaning, and particularly relates to an underwater cavitation cleaning disc, device and system. According to the underwater cavitation cleaning system, multiple sets of cavitation spray heads are adopted to work at the same time, the area of a cleaning region is larger, each cavitation disc is internally provided with the multiple cavitation spray heads, the positions and the number of cavitation spray pipes and the spray heads can be adjusted at any time, each cavitation disc is controlled by one cavitation control electromagnetic valve and one pressure sensor; and the cavitation intensity of different cavitation discs can be collectively or independently controlled by a controller. The device is further provided with backflushing spray heads used for offsetting impact force brought by the cavitation spray heads, the device can reach the optimal cleaning position during operation, each backflushing spray head is controlled bya backflushing spray head pressure sensor and an electromagnetic valve, and spatial position adjustment within a small range can be achieved. The using method is flexible, the device can be hoisted into water from a ship body to be used and can also be installed on an underwater robot or an underwater navigation body, the structure is simple, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of underwater cleaning, and in particular relates to an underwater cavitation cleaning disk, device and system. Background technique [0002] With the development of science and technology, a large number of marine structures, submarine oil facilities, pipelines, ships and other structures have been put into the marine environment. Due to the long-term infiltration and operation of seawater species, the outer surface of the structures will form quite thick sea creatures. At the same time, metal structures will produce large areas of corrosion and damage on the surface of their shells. At the same time, marine organisms such as algae and shells will also adhere to the hull or underwater vehicle, which seriously affects the sailing speed and weight of the hull. Reduce the consumption of cost and shorten the service life of the ship. Using cavitation jet cleaning technology, various underwater facilities can b...
