Embodiment Construction

[0017] In the accompanying drawings, the plate-shaped or planar air-permeable and water-blocking material is fixedly supported on the ventilation pipeline (3) to form the outer shell (2) of the object running in the water; the ventilation pipeline (3) is fixed on the body of the object running in the water. On the inner shell (1); through a certain number of air holes on the ventilation line (3), the pressure gas (4) is passed into the gap between the double shells, and when it reaches a certain pressure, it will The outer casing (2) of the moving object in the water will pass through, and a layer of expansion bubbles (5) will be formed on the surface of the side contacting the water, which will connect the water with the outer casing (2) of the moving object in the water. The surface is isolated, and the pollutants on the surface of the outer shell (2) of the running object in the water are cleaned at any time.

Abstract

The invention provides an air bubble anti-friction and corrosion-resistant structure of the surface of an object moving in water. The structure is characterized by squeezing out air at a certain pressure from a breathable waterproof material and generating expanded air bubbles to separate the outer surface of the object moving in water from the water. By using the breathable waterproof materials, all or partial outer surface, contacted with the water, of the object moving in the water are closely packaged to form a double-layer shell structure; the air at a certain pressure is charged in the gap between the double-layer shells; and the air penetrates the outer-layer shell and forms a layer of expanded air bubbles on the surface of the side contacted with the water, the surface of the outer-layer shell is separated from the water, and pollutants on the surface of the outer-layer shell are washed away at any moment.

Description

technical field [0001] The invention relates to an anti-friction and anti-corrosion structure on the surface of an object running in water. Background technique [0002] We know that water is about 800 times the frictional resistance of air. The method of generating air bubbles on the surface of an object running in water can greatly reduce its frictional resistance when running. [0003] Although people have already carried out very in-depth research in this area and proposed many related inventions and patents, there are some difficult problems in the shell structure, manufacturing process, manufacturing cost, anti-friction effect, etc. This method has not been practically applied so far. [0004] In addition, in terms of shell anticorrosion, the method of continuous improvement and perfection of shell materials and surface coatings adopted by people seems to have reached the peak and come to an end. Contents of the invention [0005] For this reason, the present inve...
