Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

As shown in Figure of description 1,2; a kind of elastic power cable; including inner core 1, protection set 2; inner core 1 described in multiply is arranged in protection set 2; described protection set 2 includes tensile layer 23, cushion 22, wearing course 21 the most successively; described cushion 22 includes inflating buffer strip 222, bipeltate band 221, and axially arranged in described inflation buffer strip 222 have several buffer air bags 223, and described inflation buffer strip 222 is spirally wound on tensile layer 23 outer surface.

nullSuch as Figure of description 1、2、Shown in 3，Multiply inner core 1 becomes a power cable completely by protection set 2 parcel，Inflation buffer strip 222 is arranged with bipeltate band 221 spiral，And due to several buffer air bags 223 axially arranged in inflation buffer strip 222，And it is filled with gas in buffer air bag 223，Thus air can be compressed after pressurized by buffer air bag 223，Thus buffer air bag 223 can produce preferably deformation，Thus buffer air bag 223 can produce bigger deformation when laying power cable and encountering bending，And owing to being additionally provided with bipeltate band 221 outside inflating buffer strip 222 weeks，So that power cable easily produces bending，Consequently facilitating the laying of power cable，Owing to bipeltate band 221 is internal, there is more crafters，Thus time bipeltate band 221 be easily compressed，And compression after the generation that is not easy return bullet，Thus first bipeltate band 221 creates compression when bending，So that the decrement of buffer air bag 223 reduces，From but buffer air bag 223 can also keep preferable elasticity，Thus effectively maintain the buffering effect of buffer air bag 223，And owing to the elasticity of buffer air bag 223 is preferable，After losing conflict outside power cable，Also power cable can be effectively made to restore by the elastic reaction of buffer air bag 223，And owing to inflation buffer strip 222 spiral is arranged，Thus when power cable is subject to the biggest deformation，Inflation buffer strip 222 also can move to two ends，Thus effectively avoid buffer air bag 223 and produce excessive deformation and produce and rupture，Effectively raise the service life of buffer air bag 223.

Such as Figure of description 1, 2, shown in 3, described buffer air bag 223 is oval, owing to buffer air bag 223 is oval, thus easy pressurized is deformed in the middle part of buffer air bag 223, thus improve the elasticity of buffer air bag 223, thus effectively raise buffering effect, and when being subject to bigger pressure, buffer air bag 223 volume diminishes after being compressed, thus adjacent two buffer air bag 223 ends can be interleaved, so that being extruded, kink potential energy sky is opened, thus effectively avoid buffer air bag 223 pressurized and excessive deformation, effectively avoid buffer air bag 223 generation to rupture, thus effectively raise the service life of buffer air bag 223.

nullAs shown in Figure of description 2，Between described protection set 2 and inner core 1, gap location is provided with buffer fillings layer 3，Described buffer fillings layer 3 includes fill-in pad 31、Some inflation filling tapes 32，Axially arranged in described inflation filling tape 32 have several to fill air bag 33，Inflation filling tape 32 is filled on gap bigger between inner core 1 and protection set 2，Fill-in pad 31 is filled in interior and protects on gap less between set 2，So that the gap that inner core 1 and protection overlap 2 is completely filled with，And due in inflation filling tape 32 axially arranged several fill air bags 33，Thus inflated body in filling air bag 33，Thus it is the lightest to fill air bag 33 weight，So that whole piece inflation filling tape 32 is lighter，Thus it is effectively reduced the weight of whole piece power cable，Thus the quality after power cable winds the most effectively alleviates，Consequently facilitating the winding bucket after one group of power cable of winding is easy to carrying，And individually fill air bag 33 owing to being provided that in inflation filling tape 32，And filling air bag 33 has good elasticity，And coordinate with the effective of buffer air bag 223 by filling air bag 33，Effectively raise elastic force radially，Thus improve the effect of buffering，And be the most easily deformed when bending，Consequently facilitating the laying of power cable.
