Abstract

The invention discloses a marine intelligent sealing ring with self-generating function. The thick lip of the lip-shaped body is buried with micro-electrode contacts. When seawater leaks, a short circuit occurs between the micro-electrode contacts, and the generated electrical signal is sent to The circuit board, the circuit board outputs electrical signals to the actuator of the tightening spring to adjust the tightness of the sealing ring, ensuring that the sealing ring can recover the sealing performance in time after leakage; the permanent magnet in the sealing ring moves along the metal under the action of ocean waves. The slideway of the casing slides irregularly, and the coil generates alternating induction current, which is converted into direct current by the rectifier circuit in the circuit board to charge the battery, and the battery supplies power to the entire system. Compared with the prior art, the present invention has the advantages of high integration, intelligent detection of whether the seal is leaking, and improved reliability and service life of the seal.

Description

technical field [0001] The invention relates to the technical field of marine sealing, in particular to an intelligent marine sealing ring with self-generating function. Background technique [0002] At present, there are many kinds of rotary seals used in the marine environment. In the actual application process, a reasonable type and model are generally selected according to the working conditions and environment. Due to the humid marine environment, sometimes working underwater, and difficult maintenance, higher requirements are placed on the service life of the sealing ring. Generally, the sealing ring has a short service life and is prone to aging and wear, which seriously affects the reliability of marine equipment. [0003] Therefore, for the special application scenario of the ocean and the special sealing medium of seawater, it is necessary to take measures to improve the service life of the sealing ring. Especially in the case of insufficient sealing contact force...
