Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Examples
Referring to fig. 1-3, a moisture-proof cable comprises a conductor core 1, wherein an insulating layer 2, a blocking layer 3, a moisture-proof pipeline 4 and an outer protective layer 5 are fixedly sleeved on the outer side of the conductor core 1 in sequence, a hydrophobic layer is coated on the outer side of the blocking layer 3, and a plurality of drainage devices are sequentially distributed on the moisture-proof cable;
the drainage device comprises two separated permanent magnet rings 6 which are fixedly connected in a moisture-proof pipeline 4 in a sealing manner, and a second annular iron core 7 and a first annular iron core 12 which are connected in the moisture-proof pipeline 4 in a sliding manner in an airtight manner, the central lines of the two separated permanent magnet rings 6 are the same as the central lines of the second annular iron core 7 and the second annular iron core 12, the outer protective layer 5 is respectively arranged on the outer side of the second annular iron core 7 and the outer side of the first annular iron core 12 in an embedded manner and is not provided with continuous coils, the rotating directions of the first coils 13 and the second coils 8 are opposite, the moisture-proof pipeline 4 is filled with water-absorbing expansion materials between the second annular iron core 7, the first annular iron core 12 and the separated permanent magnet rings 6, the outer peripheral wall of the blocking layer 3 is provided with shielding rings 14 at positions close to the first annular iron core 12 and the second annular iron core 7, and the, at least two apopores 9 have been seted up in outer jacket 5 and in separating one side that permanent magnet ring 6 is close to first annular iron core 12, are provided with one-way membrane 10 in the apopore 9, and one-way membrane 10 makes aqueous humor only can flow from dampproofing pipeline 4, apopore 9, carries out the separation to external aqueous humor.
The first coil 8 and the second coil 13 have the same number of turns and diameter, so that the magnetic field intensity generated by the first coil 8 and the second coil 13 is ensured to be the same.
The circumference of the peripheral wall of the first annular iron core 12 and the second annular iron core 7 is uniformly and fixedly connected with a plurality of limiting blocks 11, the inner wall of the outer protective layer 5 is provided with a limiting groove which is in airtight sliding connection with the limiting blocks 11, so that the first annular iron core 12 and the second annular iron core 7 are more stable in the axial sliding process, the number of the limiting blocks 11 is 2-4, and the number is not too much or too little.
When the moisture-proof cable is used, once the outer protective layer 5 is damaged, water vapor enters the moisture-proof pipeline 4, on one hand, the hydrophobic layer prevents the water vapor from continuously entering the cable through the blocking layer 3, the water-absorbing expansion material expands after absorbing water, and the absorbed water is extruded out through the water outlet hole 9 in a certain length, on the other hand, the first annular iron core 12 and the first coil 8 can form a first electromagnet, the second annular iron core 7 and the second coil 13 form a second electromagnet, it needs to be explained that the first electromagnet, the second electromagnet and the separation permanent magnet ring 6 close to the first electromagnet and the second electromagnet are arranged in a mutually-repellent mode, and the first electromagnet and the second electromagnet are arranged in a mutually-repellent mode due to the fact that the rotating directions of the first coil 8 and the second coil 13 are opposite;
