Description

一种耐喷淋振动的阻燃耐火电力电缆 技术领域
本发明涉及阻燃耐火电力电缆领域，具体来说，涉及一种耐喷淋振动的阻燃耐火电力电缆。
背景技术
耐火电线电缆是指在电线电缆火灾事故中，该电线电缆产品能够在外部火焰依然燃烧的情况下，能够坚持一定时间的正常运作，保持电线电缆线路完整性并保持线路设备的正常运转的电缆。
耐火电线电缆按国家标准可分为二个等级：A级和B级。通常表示为N HA类以及N H B类。判断一个电线电缆产品是否属于耐火电线电缆，与电线电缆产品自身是否具有自熄性无关。阻燃电线电缆的最大功能在于电线电缆产品自身的难燃性。耐火电线电缆通常能够在750～800℃的火焰温度下至少保持180分钟的正常运转。
耐火电缆中还有一种特殊的特种电缆，称为防火电线电缆。它是以无缝铜管作为护套，以氧化镁做为绝缘材料制造而成。因其材料的特殊性，防火电线电缆既不燃烧，也不延燃。经实验表明：在800～900℃中2小时，防火电线电缆依然正常运作，在1000℃下30分钟内依然持续正常运转。
目前，市场上主要有刚性和柔性两种防火电缆，其主要区别是：刚性的是以氧化镁作为绝缘的铜芯铜护套矿物绝缘电缆；柔性的是以云母带作为绝缘的铜芯轧纹铜护套防火电缆。这两种结构的电缆都需要在专用的设备上进行生产，设备投资较大，电缆加II艺较复杂，且绝缘易受潮，施工、安装不方便。 并且由于刚性防火电缆的强度较高，对线芯的保护强度较大，在部分高振动的区域环境下，其刚性防火电缆在高强度的振动下，容易导致内部的线芯发生脱离，高振动的区域环境下，其柔性防火电缆在高强度的振动下，其线芯不一脱离，而在较大长度的弯曲状态下，柔性防火电缆导致线芯发生折断问题。

所述主轴上套有旋转的内套筒，内套筒插入外套筒内与弹簧的另一端连接。
进一步地，所述相邻内被层之间的最短距离不小于5cm，并且所述内被层为阻燃剂浸染后的多层无碱玻璃丝带绕包构成。
进一步地，所述前座和后座分别位于第一旋转盘和第二旋转盘的圆心处，并且前座和后座所在平面形成的夹角小于15°，并且第一旋转盘和第二旋转盘的截面为T型，内被层上加工有供第一旋转盘和第二旋转盘插入的T型槽，第一旋转盘和第二旋转盘在T型槽内旋转。
进一步地，所述内圈和外圈在未振动状态下同圆心，在振动时，内圈通过防振组件在外圈内移动，用于吸收振动产生的动能。
进一步地，所述中心块为圆型结构，主轴位于中心块偏圆心的位置。

3、本发明提供了耐喷淋振动的阻燃耐火电力电缆，内圈或者外圈在振动的影响下，内圈会在外圈的径向方向移动，则会导致一部分的防振组件发生压缩，另一部分的防振组件发生拉伸，内套筒带动主轴绕中心块旋转，并且主轴在旋转的过程中，不同位置的弹簧会压缩或者拉长，从而通过弹簧吸收振动的动力并且配合主轴的旋转，将振动产生的能量转换为势能以及离心力，从而快速将能量吸收，完成防振的目的。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本发明保护的范围。
参阅附图1-8所示一种耐喷淋振动的阻燃耐火电力电缆，包括阻燃外被1，阻燃外被1的设置用于实现电力电缆的初步阻燃，进行耐火处理，阻燃外被1内设置有外防水带2，外防水带2采用耐水的材料制备，用于电力电缆的初步防水，外防水带2内设置阻燃内被3，阻燃内被3的内壁与防振组件4相接，防振组件4的内侧与导体5连接，通过设置的阻燃内被3进行二次阻燃，避免单一阻燃的方式无法做到完全阻燃的方式，设置的防振组件4对导体5进行保护，避免振动造成损伤。
导体5包括铜导体51、内防水层52、绝缘层53和屏蔽层54，铜导体51的外部包覆绝缘层53，绝缘层53的外部包覆屏蔽层54，屏蔽层54置于内防水层52内，内防水层52内填充有包覆屏蔽层54的隔热填充料6，设置的屏蔽层54和绝缘层53以同心角度设置，杜绝了绝缘电场强度分布不均匀现象的产生，保证了装配时不易顺利脱皮，弯曲及耐压性能优异，表面无裂纹，卷绕后耐压绝缘无击穿，阻燃外被1和阻燃内被3具有良好的耐化学腐蚀性、耐高温性、耐氧化性、耐候性、加工性及抗疲劳和 蠕变性，配合外防水带2和内防水层52的双层防水，则在长时间喷淋的状态下，也能达到长时间使用的目的。
阻燃内被3包括内被层31和折弯组件32，内被层31和折弯组件32之间交错连接，内被层31的外壁与外防水带2内壁连接，通过设置的多个内被层31和折弯组件32相互交错的设置，而让相邻的内被层31之间通过折弯组件32实现折弯的目的，并且折弯处于有限制的折弯，则不会导致局部折弯的角度过大，让电力线缆发生损坏；
折弯组件32包括第一旋转盘321、第二旋转盘322、连杆323、前座324和后座325，第一旋转盘321和第二旋转盘322分别插入相邻的内被层31侧面上，第一旋转盘321和第二旋转盘322可以绕内被层31旋转，前座324和后座325分别固定在连杆323的两端上，前一位连杆323的后座325与后一位连杆323的前座324之间通过销轴活动连接，位于最外侧的两个连杆323的前座324和后座325分别固定在第一旋转盘321和第二旋转盘322上，相邻的连杆323可以绕前座324和后座325之间旋转，通过设置的多个连杆323，则让折弯组件32的折弯角度以及平顺性更高，同时折弯的曲率也更加平衡，用于保护导体5避免折弯的角度过大；
相邻内被层31之间的最短距离不小于5cm，并且内被层31为阻燃剂浸染后的多层无碱玻璃丝带绕包构成。
前座324和后座325分别位于第一旋转盘321和第二旋转盘322的圆心处，并且前座324和后座325所在平面形成的夹角小于15°，并且第 一旋转盘321和第二旋转盘322的截面为T型，内被层31上加工有供第一旋转盘321和第二旋转盘322插入的T型槽，第一旋转盘321和第二旋转盘322在T型槽内旋转，第一旋转盘321和第二旋转盘322在T型槽内旋转，不会脱离；
四个防振组件4为一组，每组防振组件4等间距的设置在单个内被层31内，防振组件4包括外圈41、内圈42、限位环43、中心块44、主轴45、外套筒46、内套筒47和弹簧48，外圈41固定在内被层31的内壁上，外圈41的内周面等间距的分布有限位环43，限位环43的内周面加工有一圈环槽431；
中心块44的外周面固定有一圈挡环441，中心块44插入限位环43内，挡环441插入环槽431内，中心块44绕限位环43旋转，中心块44的一侧固定有竖直的主轴45，通过设置的挡环441插入环槽431的方式，中心块44在限位环43内旋转，并且中心块44不会从限位环43中脱离；
内圈42套在内防水层52的外壁上，内圈42与外圈41相对的外壁上固定有销座411，销座411与限位环43一一对应，销座411与外套筒46连接，弹簧48置于外套筒46内，弹簧48的一端与外套筒46的内壁固定；
主轴45上套有旋转的内套筒47，内套筒47插入外套筒46内与弹簧48的另一端连接，通过设置的内套筒47插入外套筒46内的方式，在振动产生，内圈42和外圈41在未振动状态下同圆心，在振动时，内圈42通过防振组件4在外圈41内移动，用于吸收振动产生的动能。
中心块44为圆型结构，主轴45位于中心块44偏圆心的位置，内圈42或者外圈41在振动的影响下，内圈42会在外圈41的径向方向移动，则会导致一部分的防振组件4发生压缩，另一部分的防振组件4发生拉伸， 内套筒47带动主轴45绕中心块44旋转，并且主轴45在旋转的过程中，不同位置的弹簧48会压缩或者拉长，从而通过弹簧48吸收振动的动力并且配合主轴45的旋转，将振动产生的能量转换为势能以及离心力，从而快速将能量吸收，完成防振的目的。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
