Moisture-proof floating cable

Abstract

The invention discloses a moisture-proof floating cable, and belongs to the field of cables. The moisture-proof floating cable comprises a cable core, a moisture-proof protection layer and an outer sheath; the outer side of the cable core is sleeved with an isolation layer, the moisture-proof protection layer comprises an inner moisture-proof layer, a rotating sleeve and an outer moisture-proof layer, the inner moisture-proof layer is arranged on the outer side of the isolation layer in a winding mode, and the inner end side of the inner moisture-proof layer is fixedly connected to the isolation layer; the inner damp-proof layer is sleeved with the rotating sleeve, and the outer end side of the inner damp-proof layer is fixedly connected to the rotating sleeve. Raised lines are fixed on the outer surface of the rotating sleeve along the circumferential side at equal intervals; water swelling structures in one-to-one correspondence with the raised lines are fixed on the inner side surface of the outer damp-proof layer along the circumferential side of the outer damp-proof layer; the water swelling structure comprises a water swelling body, a blocking assembly and an elastic body, the inner side face of the water swelling body makes contact with the outer side face of the rotating sleeve, and one side face of the water swelling body makes contact with one corresponding protruding strip. The floating function of the floating cable can be effectively achieved, the damp-proof structure is ingenious in design, and the good damp-proof effect is achieved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a moisture-proof floating cable. Background technique [0002] A cable is a tool composed of multiple wires to transmit electrical energy or electrical signals. With the continuous progress of society, the use of electrical energy and electrical signals is becoming more and more common. Cables have become an indispensable part of our lives. In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, so cables are also needed for power supply and communication, and ordinary cables are difficult to support on the water surface, so floating cables are produced. [0003] Floating cables are cables that float on the water surface during use. Due to long-term contact with water during application, floating cables need to have strong waterproof and moisture-proof performance. However, the existing floating cables mostly rely on waterproof sheaths and waterpro...

In waters such as oceans and rivers, due to the rapid development, mechanical equipment is needed, so cables are also needed for power supply and communication, and ordinary cables are difficult to support on the water surface, so floating cables are produced.

[0003] Floating cables are cables that float on the water surface during use. Due to long-term contact with water during application, floating cables need to have strong waterproof and moisture-proof performance. However, the existing floating cables mostly rely on waterproof sheaths and waterproof tapes to achieve waterproof and moisture-proof functions. , the moisture-proof structure is simple, and the moisture-proof effect is poor
