specific Embodiment

[0030]Specific embodiment: the vacuum suction cup is adsorbed on the surface of the deck after vacuuming, and the water suction cup contacts the surface of the deck under the action of the upper spring, and the limit pin of the universal wheel bracket is pulled out, so that the universal wheel bracket moves upward, and the bracket is downward at the same time Under the action of the spring and the bracket, the cleaning cabin is firmly fixed on the deck and maintains a good seal; inject the aqueous solution into the cleaning cabin to a height of 50 mm from the deck surface, and open the air inlet valve to increase the temperature of the cleaning cabin. Observe the intake flow from the micro mass flowmeter, control the pressure in the cleaning cabin through the pressure control device, open the intake valve to pressurize the cleaning cabin to 0.5MPa; open the ultrasonic vibration plate and move the ultrasonic vibration plate longitudinally to make it Several cavitation bubbles ar...

Abstract

The invention relates to the field of cavitation cleaning, in particular to a device and method for cleaning the surface of a deck through cavitation bubbles. The innovation point of the device is that a maritime work ship deck cleaning and rust removing device which can be adsorbed on the surface of a deck and can still work normally when a ship body is violently shaken is designed, and a brand new device for improving the cavitation effect by adjusting the pressure of a cleaning cabin is provided; according to the method for conducting rough cleaning and fine cleaning rust removal on the deck through the ultrasonic cavitation technology and the laser cavitation technology, the fixed-point cleaning rust removal of the deck can be achieved, and the rust removal efficiency is improved.

Description

technical field [0001] The invention belongs to the technology of cavitation cleaning and derusting, in particular to a device and method for pressurized cavitation cleaning of the deck of a marine engineering ship, which can clean the deck in harsh marine environments. Background technique [0002] When the ultrasonic wave acts on the liquid, it can produce tens of thousands of small bubbles. The bubbles in the liquid vibrate under the action of the sound field to generate shock waves and high-speed jets that act on the wall, causing cavitation and peeling off the wall. The principle of laser cavitation is similar to this. When the laser acts on the liquid, if the laser energy reaches the breakdown threshold of the liquid medium, the liquid will be broken down to generate a plasma cavity, and the plasma cavity will continue to absorb the laser energy, which will accelerate the expansion and form Cavitation. When the cavitation moves near the solid-liquid interface, due to ...
