Abstract
The invention provides an intelligent sealing ring applicable to ocean current generation. The intelligent sealing ring comprises a lip-shaped body, wherein two miniature electrode contacts are buried in the back lip position of the lip-shaped body, and a tight hooping spring is also arranged on the lip-shaped body. In the normal work, no current exists between the two miniature electrode contacts, when micro leakage occurs, micro current exists between two electrodes, when a value reaches a threshold value, an actuator arranged on the tight hooping spring is driven through a signal magnifying device, the hooping force is enhanced, and the sealing capability is improved. The intelligent sealing ring has the advantages that the service life of an oil seal is prolonged, the reliability of the oil seal is improved, and the equipment fault caused by sealing stability problem can be enabled to be avoided in a long maintenance period of the ocean current generation.
Description
Technical field
The present invention relates to the seal ring field, particularly a kind of intelligent seal ring that is applicable to current power generation.
Background technique
At present, the kind of seal ring is a lot, generally is to select rational structure and combination to realize sealing function according to different Environmental Conditions with requiring.But problems such as wearing out appears in seal ring in the course of the work, wearing and tearing finally cause sealing function to lose efficacy.For the particular surroundings and the functional requirement of current power generation, adapt to this special medium of seawater, avoid corroding the seal ring excessive wear that causes with the mutual coupling of wearing and tearing, surface layer peeling, stress relaxation or the like various of failure.
Summary of the invention
In order to overcome the defective of above-mentioned existing technology; The object of the present invention is to provide a kind of intelligent seal ring that is applicable to current power generation; Can avoid the conventional seals circle not enough; Improve working life, the reliability of oil sealing, can guarantee in the longer service cycle of current power generation, the stability problem because of sealing does not cause equipment failure.
In order to achieve the above object, technological scheme of the present invention is achieved in that
A kind of intelligent seal ring that is applicable to current power generation comprises lip type body 3, is inlaid with metal frame 4 in the lip type body 3, is embedded with two microelectrode contacts 2 at the posterior lip position of lip type body 3, and the arranged outside of lip type body 3 has banding spring 1.
Described microelectrode contact 2 is silver-plated microcontact.
The actuator of accepting current signal is equipped with in described banding spring 1 inside.
The present invention is used for the narrow limitation that the seawater seal ring does not have detection and automatic adjustment capability in order to overcome at present, fills up the blank in this technical field, improves sealability, satisfies the reliability that requires in the current power generation.During proper functioning, no current between two microelectrode contacts, if little electric current appears in tiny leakage between two electrodes, when numerical value reached the bank value, through signal amplifying apparatus, the actuator of drive installation on the banding spring increased tightening force, improves sealability.
Good effect of the present invention is: (1) because seal ring itself can be discerned seawater automatically leaks, and utilizes tensioned to cut off leak path, makes the reliability of seal ring strengthen, and improved working life significantly; (2) broken through the conventional seals circle in the shortcoming that does not have frequently to change under the prerequisite that lost efficacy replacing, reduced a large amount of wastes, and solved since frequent change bring influence efficiency.(3) equipment overhaul cycle is longer in the adaptation current power generation, to the high requirement of reliability requirement of sealing
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the circuit diagram that the present invention detects leakage.
Embodiment
With reference to the accompanying drawings the present invention is described in detail.
With reference to Fig. 1; A kind of intelligent seal ring that is applicable to current power generation; Comprise lip type body 3, be inlaid with metal frame 4 in the lip type body 3, be embedded with two microelectrode contacts 2 at the posterior lip position of lip type body 3; Utilize the electric conductivity of seawater to form the closed-loop path, judge through change in current whether seawater tiny leakage takes place; The arranged outside of lip type body 3 has banding spring 1, and banding spring 1 is accepted the signal that electric current changes, and increases tension force, forces sealing lip to hug running shaft, cuts off leak path, and the loop is broken off, and electric current is zero.
Described microelectrode contact 2 is silver-plated microcontact, and during proper functioning, no current between two contacts when taking place to leak, little electric current occurs, through amplifier, obtains the bank value signal, surpasses the bank value signal, and the actuator of banding spring is sent action command.
The actuator of accepting current signal is equipped with in described banding spring 1 inside, can accept current signal.
Working principle of the present invention is: when the seawater tiny leakage takes place; Because the electric conductivity of seawater; Microelectrode contact 2, current detection circuit 5 and power supply 6 have just formed the closed-loop path, when current detection circuit takes place to surpass the numerical value of setting the bank value, can judge the generation tiny leakage.The action command that actuator received current testing circuit on the banding spring 1 sends; Progressively improving tightening force, is zero up to the electric current of current detection circuit, and banding spring 1 stops to be tensioned; Blocking-up is leaked; Reach the purpose of automatic adjustment sealability, prolonged the working life of seal ring, guaranteed the reliability of sealing simultaneously.
Claims (3)
