Abstract

The utility model provides a spring cable for an underwater moving power station. The spring cable comprises a conductor, wherein the conductor comprises guide wires and a plurality of polypropylene insulation materials arranged outside the guide wires. A separation layer is arranged outside the conductor, and a polyurethane protecting sleeve is arranged on the separation layer. The cable is coiled into a spring structure. Through change of a structure of the cable, the spring cable is coiled into the spring structure, so the spring cable can automatically stretch through buoyancy, and automatically shorten through retraction force of the spring cable, and simplifies operation and use of the cable, does not need stretching and shortening in the way that a motor drives a rotary drum, saves electric power, reduces abrasion and coiling of the cable in the automatic stretching and shortening process, and prolongs service life of the cable.

Description

Mobile power station is used spring cable under water

Technical field

The utility model relates to the cable technology field, relates in particular to a kind of mobile power station under water and uses spring cable.

Background technology

Mobile power station is used cable under water, requires along with the up-down of water level can automatic deploying and retracting.In the prior art,, cable is wrapped on the cylinder, and rotates to carry out the folding and unfolding of cable through the driven by motor cylinder in order to satisfy above-mentioned job requirements.The major defect of this mode is in the twisted and released of the cable process, to need to consume a large amount of electric energy, and cable is often reeled the useful life of having reduced cable in folding and unfolding.

Therefore, how mobile power station is under water designed with cable, make this cable can carry out automatic deploying and retracting, simplify the use operation of cable, energy savings in the useful life of improving cable, has become the technical problem that those skilled in the art are badly in need of solving.

The utility model content

Problem to the prior art existence; The purpose of the utility model is to propose a kind of mobile power station under water and uses spring cable; This spring cable can extend through buoyancy automatically, and the retraction force through spring cable can shorten automatically, has simplified cable and has used operation; Practice thrift electric energy, improved the useful life of cable.

For reaching this purpose, the utility model adopts following technical scheme:

A kind of mobile power station is under water used spring cable, and said cable comprises conductor, and said conductor comprises the polypropylene insulation that lead is outer with being located at lead, outside said conductor, is provided with separator, outside said separator, is provided with polyurethane jacket; Said coil of cable coiled spring-like structures.

Preferably, said conductor comprises many first conductors and second conductor; Said first conductor comprises stranded wire and is located at its outer polypropylene insulation; Said second conductor comprises at least two root conductors and is located at its outer separator, outside separator, is provided with screen, and wherein, every root conductor comprises stranded wire and is located at its outer polypropylene insulation.

Preferably, the quantity of said first conductor and second conductor equates, and arranges according to circle alternate.

Preferably, the home position at said cable is provided with gasket for packing.

Preferably, said screen is a copper wire establishment screen.

Preferably, said polyurethane jacket is the EU sheath.

Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:

A kind of mobile power station is under water used spring cable in the utility model, and said cable comprises conductor, and said conductor comprises the polypropylene insulation that lead is outer with being located at lead, outside said conductor, is provided with separator, outside said separator, is provided with polyurethane jacket; Said coil of cable coiled spring-like structures.Through changing the structure of cable, with said coil of cable coiled spring-like structures, this spring cable can extend through buoyancy automatically, and the retraction force through spring cable can shorten automatically, has simplified cable and has used operation; Need not to adopt the motor-driven cylinder to carry out the folding and unfolding of cable, practiced thrift electric energy, in the automatic deploying and retracting process, reduced the friction and the coiling of cable, improved cable useful life.

Description of drawings

Fig. 1 is the cross-sectional view of a kind of mobile power station under water of the utility model proposition with spring cable.

Fig. 2 is the structural representation of Fig. 1 medi-spring cable.

Embodiment

Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through embodiment:

As depicted in figs. 1 and 2, a kind of mobile power station under water that proposes for the utility model is with the cross-sectional view of spring cable, and Fig. 2 is the structural representation of Fig. 1 medi-spring cable

With reference to accompanying drawing; A kind of mobile power station under water that the utility model proposes is used spring cable; Said cable comprises conductor; Said conductor comprises first conductor 1 and second conductor 2 (as comprising two first conductors 1 and two first conductors 2 among Fig. 1) of equivalent amount, and said first conductor 1 and second conductor 2 are arranged according to circle alternate, at its home position gasket for packing 3 be set; Said first conductor 1 comprises stranded wire 11 and is located at its outer polypropylene insulation 12; Said second conductor 2 comprises at least two root conductors and is located at its outer separator 23, outside separator 23, is provided with copper wire establishment screen 24, and wherein, every root conductor comprises stranded wire 21 and is located at its outer polypropylene insulation 22.Outside said conductor, be provided with separator 4, outside said separator 4, be provided with EU sheath 5; Said coil of cable coiled spring-like structures.

In above-mentioned spring cable, the high temperature setting performance of propylene insulation and polyurethane jacket is all relatively good, with the cable of above-mentioned two kinds of materials processings; Cable is wound in spring-like earlier, is placed on then in the mould, after handling a period of time under the uniform temperature; Just can make cable keep the spring-like structures of processing procedure; And spring cable can extend under tension, removes pulling force, and spring cable is retracted to original state again.

Under water in the mobile power station, this spring cable can extend through buoyancy automatically with above-mentioned cable application, and the retraction force through spring cable can shorten automatically, has simplified cable and has used operation; Need not to adopt the motor-driven cylinder to carry out the folding and unfolding of cable, practiced thrift electric energy, in the automatic deploying and retracting process, reduced the friction and the coiling of cable, improved cable useful life.

Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of utility model and the various improvement that technical scheme is carried out; Or the design of utility model and technical scheme are directly applied to other occasion without improving, all in the protection range of the utility model.
