Power-adjustable underwater building cleaning and maintaining device

Abstract

The invention discloses a power-adjustable underwater building cleaning and maintaining device which comprises an ultrasonic signal generator, a driving isolation circuit, an ultrasonic power amplifying circuit, a matching network, a tuning inductor, a pressure sensor, a controller, a control panel, a pressure adjuster and a transducer. The pressure sensor is installed on the transducer and used for sensing a water pressure signal capable of reflecting water depth of the transducer, converting the signal through an analog / digital (A / D) conversion circuit and transmitting the converted signal to the controller. The controller generates transducer depth information according to the water pressure signal and outputs the information to the control panel. The pressure adjuster is connected with the voltage input end of the ultrasonic power amplifying circuit and used for adjusting a voltage input value of the ultrasonic power amplifying circuit according to the transducer depth information displayed by the control panel. The device achieves large-area high-efficiency cleaning of underwater buildings, is adjustable in cleaning power, avoids the fact that a cleaning effect becomes poor with increase of depth and the surfaces of the buildings are damaged by too large power, achieves complete maintenance of the buildings like dams and remarkably improves working efficiency.

Description

technical field [0001] The invention relates to an underwater structure cleaning and maintenance device with adjustable power, which belongs to the technical field of ultrasonic cleaning. Background technique [0002] At present, in today's society, with people's exploration of new energy, the water conservancy industry has been continuously developed. However, due to long-term immersion in water, scale and other attachments on the surface of gates, dams and other equipment have affected their normal functions. , In addition, due to the coverage of attachments, it is impossible to find out whether there are cracks and other safety hazards in large-scale underwater equipment, which brings great inconvenience to routine safety inspections and eventually causes equipment damage. [0003] In the prior art, the main method of cleaning underwater structures such as gates and dams is to shut down, waterproof or lift off the water surface and manually knock, and then clean with high...

Problems solved by technology

Borrowing the basic principle of ultrasonic tooth cleaning, it has been possible to clean stones in water with ultrasonic waves, but there is no report on the use of ultrasonic waves to clean large areas of deep water structures.
