Abstract

The utility model discloses an aquatic work prevents turning round floating cable, including cable core and nylon hollow tube, cable core and nylon hollow tube outer common cladding have the foaming polyolefin that the cross-section is the pear type to float the layer, the nylon hollow tube is located foaming polyolefin floats tip one side of layer's cross-section, the cable core is located foaming polyolefin floats tip one side of layer. The utility model discloses do not set up floating device alone and can make the cable float in sleep and effectually prevent that the cable rotation from beating the turn round.

Description

Anti-twisting floating cable for working in water

Technical Field

The utility model relates to a cable especially relates to a floating cable is prevented turning round in aquatic work.

Background

The existing floating cable is thick in a floating layer in order to enable the electric wire to work normally in water and ensure the floating force, and the size of the electric wire is large. There is also a way to add a floating device to the cable to ensure the wire floating force. Meanwhile, when the common floating cable works in water, twisting can be generated, wires are twisted together and even agglomerated, so that the working of equipment is influenced, and the service life of the wires can be influenced due to frequent twisting.

SUMMERY OF THE UTILITY MODEL

To the defect of above-mentioned prior art, the utility model provides an aquatic work is prevented turning round showy cable guarantees that the cable can float the use and prevent that the cable from beating to turn round in aqueous.

The utility model discloses technical scheme as follows: the utility model provides an aquatic work prevents turning round floating cable, includes cable core and nylon hollow tube, cable core and nylon hollow tube coat jointly outward and have the foaming polyolefin that the cross-section is the pear type to float the layer, the nylon hollow tube is located foaming polyolefin floats tip one side of layer's cross-section, the cable core is located foaming polyolefin floats tip one side of layer.

Preferably, the cable core comprises a plurality of twisted insulating core wires, a water-blocking wrapping tape is wrapped outside the twisted insulating core wires, and an inner sheath layer is extruded outside the water-blocking wrapping tape.

Preferably, the diameter of the nylon hollow pipe is smaller than that of the cable core.

Preferably, the inner sheath layer is a medium density polyethylene layer.

Preferably, the insulated core wire comprises a conductor, and the conductor is coated with a low-density polyethylene insulating layer.

The utility model provides a technical scheme's advantage lies in: the cable has good floating performance without any additional floating device. Adopt nylon hollow tube and big end down's pear type cross-section structure, guaranteed the mechanical strength of cable, effectively prevent that the cable from beating to turn round. The whole size of electric wire is less, lightweight design, and is with low costs.

Drawings

Fig. 1 is a schematic cross-sectional view of an embodiment of the twist-resistant buoyant cable operating in water.

Detailed Description

The present invention is further described in connection with the following examples, which are intended to illustrate the invention and not to limit the scope of the invention, which, after reading the present invention, are intended to cover modifications of the invention in its various equivalent forms by those skilled in the art, which fall within the scope of the appended claims.

Referring to fig. 1, the underwater working anti-twisting floating cable according to the present embodiment includes a cable core, the cable core includes four insulated core wires, the insulated core wires include a conductor 1, and a low density polyethylene insulating layer 2 is coated outside the conductor 1. The material has high insulating strength, low density and hydrolysis resistance. Four insulating heart yearns transposition stranding cable wind package band 3 that blocks water, and band 3 that blocks water extrudes inner sheath layer 4 outward, and inner sheath layer 4 plays protection heart yearn and waterproof effect for the medium density polyethylene layer, prevents that water from permeating to insulating heart yearn the inside. The foamed polyolefin floating layer 5 is coated outside the cable core, the section of the foamed polyolefin floating layer 5 is pear-shaped, the density of the material is low, the material expands and foams when being heated during extrusion to form a foaming layer, the floating force of the electric wire is ensured, and the electric wire can work in water. The cable core is located the section major part one side of the foaming polyolefin floating layer 5 of pear type, drags into a nylon hollow pipe 6 that the diameter is less than the cable core when foaming polyolefin floating layer 5 extrudes, and nylon hollow pipe 6 is located the little first one side of the section of the foaming polyolefin floating layer 5 of pear type, has further increased the cable buoyancy. 6 density of nylon air traffic control is little, and the hardness is higher, has guaranteed the certain mechanical strength of electric wire, makes the cable be difficult for controlling the distortion, simultaneously, receives the influence of 6 buoyancy of nylon air traffic control, has guaranteed that the cable is nylon air traffic control 6 one side up all the time at aquatic during operation, and the effectual cable rotation that prevents is beaten turns round.
