Although the elastic force of the power tube elastic support body I11 is not close to the head end 2 or the end 3 can still bind the cable, it needs to be replaced due to the slack at both ends of the power tube, which shortens the service life of the product and causes waste.

其中,所述的阻燃层为聚酯亚胺层,保温层为玻璃棉层,屏蔽层为铜丝与涤纶棉线交织结构层,抗腐蚀层为镀锌层,防水层为橡胶层,耐磨辅助凸块层的耐磨凸起为硬质塑料凸起,磨砂层为单面磨砂结构。
其中,所述的耐磨层I与耐磨层II为环氧树脂层。
一种高适应性电缆束缚电力管道的使用方法,其特征在于:首端或末端的弹性支撑体II交叉设置,电缆首先穿过首端的若干个弹性支撑体II之间并与弹性支撑体II内表面的耐磨层II贴合,通过弹性支撑体II对电缆进行束缚;电缆然后穿过管体的若干个弹性支撑体I之间并与弹性支撑体I外表面的耐磨层I贴合,通过弹性支撑体I对电缆进行束缚;电缆最后从末端穿过,末端与首端的束缚结构相同,完成电力管道的使用。

下面结合附图及具体实施方式对本发明的技术方案做进一步的描述。
本发明的一种高适应性电缆束缚电力管道,包括中部的管体1与管体1两端端部的首端2与末端3,管体1由内至外依次设置有阻燃层4、保温层5、屏蔽层6、抗腐蚀层7、防水层8、耐磨辅助凸块层9与磨砂层10并在阻燃层4内设有若干个弧形的弹性支撑体I11且弹性支撑体I11与电缆的接触面设有耐磨层I12;首端2与末端3的结构相同,首端2的阻燃层4部分内设有若干个弧形的弹性支撑体II13且弹性支撑体II13与电缆的接触面设有耐磨层II14;耐磨层I12位于弹性支撑体I11的外表面且耐磨层II14位于弹性支撑体II13的内表面。其中,阻燃层4内设有3个以上的弧形的弹性支撑体I11。首端2的阻燃层4部分内设有2或3个弧形的弹性支撑体II13。电缆位于弹性支 撑体I11外表面的耐磨层I12之间且位于弹性支撑体II13内表面的耐磨层II14之间。
具体的实施例,阻燃层4为聚酯亚胺层,保温层5为玻璃棉层,屏蔽层6为铜丝与涤纶棉线交织结构层,抗腐蚀层7为镀锌层,防水层8为橡胶层,耐磨辅助凸块层9的耐磨凸起为硬质塑料凸起,磨砂层10为单面磨砂结构。耐磨层I12与耐磨层II14为环氧树脂层。
一种高适应性电缆束缚电力管道的使用方法,其特征在于:首端2或末端3的弹性支撑体II13交叉设置,电缆首先穿过首端2的若干个弹性支撑体II13之间并与弹性支撑体II13内表面的耐磨层II14贴合,通过弹性支撑体II13对电缆进行束缚;电缆然后穿过管体1的若干个弹性支撑体I11之间并与弹性支撑体I11外表面的耐磨层I12贴合,通过弹性支撑体I11对电缆进行束缚;电缆最后从末端3穿过,末端3与首端2的束缚结构相同,完成电力管道的使用。
本发明的电力管道在阻燃层4的外壁设置保温层5,在保温层5的外壁设置屏蔽层6,在屏蔽层6的外壁设置抗腐蚀层7,在抗腐蚀层7的外壁设置防水层8,在防水层8的外壁设置耐磨辅助凸块层9,在耐磨辅助凸块层9的外壁设置磨砂层10。使得电力管道具有良好的阻燃性、保温性、屏蔽性、抗腐蚀性、防水性与耐磨性。可以在夏天高温时延缓老化;在冬天低温时保护电缆内部金属组织结构;有效防止土壤及植物环境对其进行腐蚀磨损。
同时,本发明的电力管道在阻燃层4内设有若干个弧形的弹性支撑体I11且弹性支撑体I11与电缆的接触面设有耐磨层I12;首端2的阻燃层4部分内设有若干个弧形的弹性支撑体II13且弹性支撑体II13与电缆的接触面设有耐磨层II14;这样的设计,在电力管道具有良好的外部耐磨性时,提高其内部耐磨性,有效延长使用寿命。
而且,电缆位于弹性支撑体I11外表面的耐磨层I12之间且位于弹性支撑体II13内表面的耐磨层II14之间。现有的电力管,往往在首端2与末端3采用与管体1一样的设计,长期的使用,弹性支撑体I11靠近首端2或末端3处的部分弹力会下降,对电缆的束缚力也会下降,虽然电力管弹性支撑体I11不靠近首端2或末端3处的部分弹力仍然可以束缚电缆,但由于电力管两端的松弛原因需要更换,缩短了产品使用寿命,造成了浪费。本发明在首端2与末端3采用了二重束缚设计,使电缆从弹性支撑体II13内侧通过,并通过若干个弹性支撑体II13对电缆进行束缚,保证了电缆的稳定性,提高了电力管两端的使用寿命,延长了产品整体的使用寿命。
