Spinning type cavitation cleaning disc

Abstract

The invention relates to the field of underwater cleaning, and provides a self-rotating cavitation cleaning disc. The cleaning disc comprises a high-pressure rotating joint, a cavitation cover, a cavitation nozzle and a sealing universal wheel. The cleaning disc has the self-adsorption capacity and can move at low resistance and flexibly steer, the cavitation nozzles have the self-rotating capacity, cavitation jet flow acts on the combination position of attachments and a working face through specific nozzle space angle and position arrangement, and it is guaranteed that cleaning is thorough and lossless. The cleaning disc can be carried on an underwater robot or a handheld cleaning device, has the advantages of being high in cleaning efficiency, good in effect, thorough in cleaning, free of damage, safe and labor-saving in operation, high in practicability and the like, and is suitable for cleaning underwater facilities such as ships, bridge piers and dams in planes, surfaces with various curvatures and small-area irregular areas.

Description

technical field [0001] The invention relates to the field of underwater cleaning, in particular to a spin-type cavitation cleaning disk. Background technique [0002] During long-term sailing or berthing, barnacles, shellfish, algae and rust spots will adhere to the surface of the hull below the waterline, which seriously affects the sailing speed and service life of the ship, and also increases fuel consumption. At present, there are several methods for the cleaning of underwater hulls at home and abroad: manual scraping, mechanical cleaning, high-pressure jet cleaning, manual cleaning by divers and robot cleaning, etc. The traditional cleaning methods all have low cleaning efficiency, poor cleaning effect, The cleaning width is narrow, the labor intensity is high, and there are different degrees of damage to the hull. [0003] At present, domestic and foreign efforts are being made to develop new underwater cleaning devices and cleaning disks, but the existing underwater ...

AI Technical Summary

Problems solved by technology

[0004](1) The existing underwater cleaning trays usually use fixed cleaning trays, which lack the ability to move with multiple degrees of freedom, and their adaptability to the working surface is poor. The ability to overcome obstacles is weak, which seriously restricts the application field of underwater cleaning discs

[0005](2) Most of the existing underwater cleaning trays do not have self-adsorption ability, and usually require divers or robots to provide sufficient bonding force for normal cleaning, operability and practicality Poor sex

[0006](3) The existing underwater cleaning trays usually use fixed nozzles or external force rotation mode. The fixed nozzles have narrow cleaning range, poor cleaning effect and low efficiency. There is often the phenomenon of missed washing or repeated washing; the structure of the external force rotation mode is complex and the reliability is poor

[0007](4) The existing underwater cleaning pan does not realize the cavitation and jet flow of the input high-pressure water in a real sense, and cannot ideally produce ultra-fine particles through cavitation. Bubbles act on the cleaning target surface and collapse to cause cavitation to achieve non-destructive cleaning, but non-destructive, efficient, thorough and energy-saving cleaning cannot be achieved

[0008](5) The existing underwater cleaning disc has a large movement resistance on the working surface and inflexible steering, which brings many difficulties to the actual operation
