Problems solved by technology

[0003] Due to the complex use environment and high humidity of the cables on ships, the rubber sheaths are easily corroded and aging quickly. However, because the use environment is close to water, when the rubber sheaths are damaged, electric leakage is prone to occur , there is a greater security risk

Embodiment 1

[0039] see figure 1 , a self-hardening waterproof rubber sheath for ship electric wires, comprising a sheath body 1, the outer end of the sheath body 1 is fixedly connected with a plurality of evenly distributed outer water resistance blocks 2, and the space between two adjacent outer water resistance blocks 2 Both are connected with an external water-blocking laminated net 3, and the external water-blocking block 2 is made of polymer water-absorbing resin material, which can absorb water hundreds or even thousands of times its own weight, and has a strong The water retention capacity makes it difficult for the water vapor to penetrate into the sheath body 1 after the water vapor is absorbed inside the outer resistance water block 2, so that it is not easy to affect the sheath body 1 while absorbing water, and the surface of the outer resistance water block 2 is coated with There is a nano-waterproof coating, which effectively prevents the air from penetrating directly into th...

Abstract

The invention discloses a self-hardening waterproof rubber sheath for a ship wire, and belongs to the field of cable sheaths. The self-hardening waterproof rubber sheath for a ship wire comprises a sheath body, and the outer end of the sheath body is fixedly connected with a plurality of outer water-blocking blocks which are uniformly distributed. An outer water blocking block and an outer water blocking laminated net are arranged; multiple layers of water vapor blocking barriers can be formed on the surface of the sheath body, so that water vapor is effectively prevented from contacting withthe surface of the sheath body, corrosion of water vapor to the surface of the sheath body is reduced, the corrosion and aging speed of the sheath body is further reduced, the annular water blocking sleeve is arranged inside; the surface of the sheath body is aged and seeps water, the sheath body is provided with the annular water blocking sleeve, hardening can be achieved, a worker can find the water seepage situation of the sheath body in time according to the overall bending performance of the electric wire, maintenance is conducted in time, potential safety hazards are reduced, meanwhile,the annular water blocking sleeve can form a water blocking barrier again in the sheath body through water absorption expansion, and water vapor is effectively prevented from continuously permeating into the sheath body.

Description

technical field [0001] The invention relates to the field of cable sheaths, in particular to a self-hardening waterproof rubber sheath for ship electric wires. Background technique [0002] Cables are usually composed of several wires or groups of wires. Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, aluminum Alloy cables and more. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. The cable is usually provided with a sheath, and the use of a cable protection sleeve to protect the cable can achieve the following advantages: 1. Good corrosion resistance, long service life, and can be used in humid saline-alkaline areas. 2. Flame retardant and heat resistant, it can be used for a long time at a high temperature of 130 degrees witho...
