Description

Automatic movable underwater cavitation cleaning disc

Technical Field

The utility model relates to a belt cleaning device especially relates to an automatic movable formula is cavitation washing dish under water.

Background

With the development of shipbuilding industry, the number of large ships is increasing day by day, however, the ship body and the deck are corroded by seawater for a long time, and the ship body is often rusted and corroded, and the ship body is greatly damaged by wild eating of conch, shell and seaweed. The surface of the ship body needs to be cleaned of adsorbates and rust regularly by manpower. Most of the existing ship cleaning tools are washed by a high-pressure cleaning machine and a manual handheld spray head.

High pressure cleaner draws water through the motor drive high pressure water pump, and the spout that carries out high pressure, high velocity of flow on the spray tube is carried with water to rethread high pressure water pump to spun water can wash the operation to other equipment, and its washing principle is: the impact force of water is greater than the adhesive force between dirt and the surface of an object, and the dirt can be peeled and washed away by high-pressure water to achieve the purpose of cleaning the surface of the object. Chinese patent application No.: 201810860202.1 discloses a high pressure washer, which describes the structure and working principle of the high pressure washer in detail. However, the high pressure cleaner can only be used for cleaning the clamping plates, and the following methods are adopted for the ship body: manual spatula, mechanical cleaning brush, ultrahigh pressure jet, underwater sand blasting, etc. These methods all have a number of drawbacks to varying degrees. If the manual scraping shovel has low efficiency, the cleaning effect is poor; cleaning brushes can only be used on large flat surfaces without any effect on irregular surfaces, but pressurized oil may leak during cleaning, causing hazards to divers and the environment. The cleaning brush can also damage paint on the surface of the cleaned object, and particularly, when the surface of the ship body is cleaned, the cleaning brush can abrade a large amount of harmful substances such as heavy metal ions in the antifouling paint to damage the water environment. Mechanical cleaning brushes, although much faster than manual scrapers, require constant stopping to clean and replace the brushes during cleaning; the ultrahigh pressure injection has great danger and low efficiency, and can be only used on small-area surfaces without paint; underwater blasting is also not available on painted surfaces and also produces secondary pollution.

Therefore, it is necessary to develop a movable type cleaning disc suitable for underwater use.
