Problems solved by technology

[0002] At present, the anechoic tile at home and abroad is the most advanced in the United States. It uses rubber with a thickness of 1mm to inject densely packed small bubbles. The principle it uses is the ancient ultrasonic cavitation theory, but the ultrasonic cavitation phenomenon is only for liquids with a diameter less than 0.1mm. Bubbles are effective

Abstract

The invention relates to a noise elimination tile capable of absorbing ultrasonic wave, belonging to the technical field of submarines. The noise elimination tile solves the problem that the submarines absorb the ultrasonic wave, thereby realizing that the submarines are more difficult to find. The noise elimination tile mainly comprises a liquid electrolyte battery, a rubber shell and a submersible pump. The noise elimination tile is characterized in that two sides of the battery communicate with the rubber shell, wherein one side of the liquid electrolyte battery is provided with the submersible pump. The noise elimination tile has simple structure and good effect, and can be applied to the submarines and underwater vehicles.

Description

technical field [0001] The invention belongs to the technical field of submarines Background technique [0002] At present, the anechoic tile at home and abroad is the most advanced in the United States. It uses rubber with a thickness of 1mm to inject densely packed small bubbles. The principle it uses is the ancient ultrasonic cavitation theory, but the ultrasonic cavitation phenomenon is only for liquids with a diameter less than 0.1mm. Bubbles work. Therefore, American anechoic tiles cannot absorb ultrasonic waves. [0003] The purpose of the invention is to solve the problem that the submarine absorbs ultrasonic waves, thereby realizing that the submarine is more difficult to be found. Contents of the invention [0004] The present invention is a kind of noise elimination that can absorb ultrasonic waves, such as figure 1 and figure 2 Shown: The liquid electrolyte battery is wrapped by a rubber casing, the two sides of the liquid electrolyte battery are connected...
