Abstract

The invention discloses an intelligent ocean sealing ring with a self-generating electricity function. Microelectrode contacts are buried in a thick lip portion of a lip-shaped body, when seawater leaks, short circuit occurs between the microelectrode contacts, a generated electrical signal is transmitted to a circuit board, the circuit board outputs an electrical signal to an actuator of a hooping spring to adjust the degree of tightness of a sealing ring, and it is guaranteed that the sealing ring restores the sealing performance in time after leakage happens; and a permanent magnet in the sealing ring irregularly slides along a sliding way of a metal shell under the action of ocean waves, coils generate alternating induced current, the alternating induced current is converted into direct current by a rectifying circuit in the circuit board to charge a battery, and the battery charges the whole system. Compared with the prior art, the ocean intelligent sealing ring with the self-generating electricity function has the advantages that high integration density is achieved, whether the seal leaks or not is intelligently detected, reliability of the seal is improved, and the servicelife is prolonged.

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...
