Description

一种基于整体框架的抗撞电气柜 所属技术领域
本发明属于电气柜技术领域，尤其涉及一种基于整体框架的抗撞电气柜。
背景技术
目前电气柜在电气布置和使用中具有不可替代的作用，电气柜是保护电气元件的主要部件。目前电气柜通过增加壁面厚度和增加内外部加强筋的数目来达到较高的抗撞效果。但是由于电气柜内部空间的限制，壁面厚度的增加和加强筋数目的增多具有一定限度，导致了电气柜的抗撞性具有一定局限性。对于具有破坏性的撞击，如树的倾倒、汽车的撞击等，采用简单的增加壁面厚度和增加加强筋的数目将无法达到抗撞要求。
本发明设计一种基于整体框架的抗撞电气柜解决如上问题。
发明内容
为解决现有技术中的上述缺陷，本发明公开一种基于整体框架的抗撞电气柜，它是采用以下技术方案来实现的。
一种基于整体框架的抗撞电气柜，其特征在于：它包括后板、底板、顶板、侧板、前板、元件安装壳、后支撑、连接支撑、U型固定块、前支撑、断裂凹槽、伸缩电线机构，其中前板、两个侧板、后板均安装在底板上且横截面为矩形，顶板安装在前板、后板和两个侧板上端；12根后支撑分成三组且三组之间并列等距地安装在后板上，每个后支撑顶端安装有一个元件安装壳，相邻元件安装壳之间通过连接支撑相互连接，每个连接支撑中间开有断裂凹槽，在每个断裂凹槽上配合有一个前支撑，前支撑一端通过U型固定块安装在前板上。
上述元件安装壳中安装有电气元件，需要通电的电气元件之间通过伸缩电线机构连接。
上述伸缩电线机构包括第一电线、电线弹簧固定块、电线弹簧、接线滑块、第二电线，其中第一电线与电气元件连接，第二电线与另一个电气元件连接；电线弹簧固定块安装在第一电线上，接线滑块滑动于第一电线上；电线弹簧嵌套在第一电线上且电线弹簧一端安装在电线弹簧固定块上，另一端安装在接线滑块上；第二电线安装在接线滑块上且第二电线通过接线滑块与第一电线通电。第二 电线通过接线滑块在第一电线上滑动，可以增加和缩短第一电线和第二电线的有效长度，电线弹簧起到复位有效长度的目的。
作为本技术的进一步改进，上述伸缩电线机构还包括软管，软管嵌套于第一电线末端，接线滑块能够压缩软管。
作为本技术的进一步改进，上述电线弹簧为拉伸弹簧。
作为本技术的进一步改进，上述后支撑硬度小于连接支撑硬度，连接支撑硬度小于前支撑硬度。
相对于传统的电气柜技术，本发明中每一个电气元件安装在元件安装壳中，每一个元件安装壳通过后支撑安装在后板上，元件安装壳之间通过连接支撑相互连接，连接支撑上具有断裂凹槽，通过U型固定块安装在前板上的前支撑一端与断裂凹槽接触，U型固定块开口方向向下，设计目的在于当前支撑受到向下的力时，容易从U型固定块中脱离。所设计的后支撑起到固定每个元件安装壳的作用；连接支撑上具有断裂凹槽，在电气柜受到撞击时连接支撑受力在断裂凹槽处弯折且不断裂，保证了各个元件安装壳在受到撞击时保持一定的间距，避免了相互碰撞。当电气柜受到撞击力，其中当前板受到冲击力时，前支撑顶住连接支撑上的断裂凹槽，连接支撑将冲击力传导到后支撑上，后支撑的硬度最小，后支撑断裂，此时元件安装壳、连接支撑、前支撑均在冲击力作用下靠近后板，进而通过向后板运动抵消冲击力保护了元件安装壳；当顶部冲击力时，顶板将冲击力传导到元件安装壳中，元件安装壳将力传导到后支撑和连接支撑上，连接支撑通过断裂凹槽将力传导到前支撑上，其中后支撑硬度最低，出现断裂，当后支撑断裂后，硬度比后支撑强的连接支撑也因为冲击力作用在断裂凹槽位置处出现弯折且不会断裂，整个元件安装壳向下移动，此时前支撑受力，在U型固定块开口方向处从U型固定块脱离，这样各个元件安装壳在冲击力作用下，一起向下移动且他们之间还会保持一定的间距，从而保护了元件安装壳。当侧板受到撞击时，元件安装壳的保护方法如顶板受到撞击时相同，即后支撑断裂，连接支撑在断裂凹槽处弯折。在电气柜中，通电之间的电气元件通过伸缩电线机构连接通电，在电气柜受到撞击时，元件之间将会发生相对位移，伸缩电线机构的电线伸缩功能能够保证正常通电。本发明在电气柜增加了后支撑、前支撑、连接支撑，通过将冲击力转移或者使元件安装壳躲避撞击的方法实现了电气柜的抗撞功能，具有较 高的实用性。

上述元件安装壳中安装有电气元件，需要通电的电气元件之间通过伸缩电线机构连接。
如图1所示，上述伸缩电线机构包括第一电线、电线弹簧固定块、电线弹簧、接线滑块、第二电线，其中第一电线与电气元件连接，第二电线与另一个电气元 件连接；电线弹簧固定块安装在第一电线上，接线滑块滑动于第一电线上；电线弹簧嵌套在第一电线上且电线弹簧一端安装在电线弹簧固定块上，另一端安装在接线滑块上；第二电线安装在接线滑块上且第二电线通过接线滑块与第一电线通电。如图1中的a、b所示，第二电线通过接线滑块在第一电线上滑动，可以增加和缩短第一电线和第二电线的有效长度，电线弹簧起到复位有效长度的目的。
如图1所示，上述伸缩电线机构还包括软管，软管嵌套于第一电线末端，接线滑块能够压缩软管。
上述电线弹簧为拉伸弹簧。
上述后支撑硬度小于连接支撑硬度，连接支撑硬度小于前支撑硬度。
综上所述，本发明中每一个电气元件安装在元件安装壳中，每一个元件安装壳通过后支撑安装在后板上，元件安装壳之间通过连接支撑相互连接，连接支撑上具有断裂凹槽，通过U型固定块安装在前板上的前支撑一端与断裂凹槽接触，U型固定块开口方向向下，设计目的在于当前支撑受到向下的力时，容易从U型固定块中脱离。所设计的后支撑起到固定每个元件安装壳的作用；连接支撑上具有断裂凹槽，在电气柜受到撞击时连接支撑受力在断裂凹槽处弯折且不断裂，保证了各个元件安装壳在受到撞击时保持一定的间距，避免了相互碰撞。
当电气柜受到撞击力，其中如图8所示，当前板受到冲击力时，前支撑顶住连接支撑上的断裂凹槽，连接支撑将冲击力传导到后支撑上，后支撑的硬度最小，后支撑断裂，此时元件安装壳、连接支撑、前支撑均在冲击力作用下靠近后板，进而通过向后板运动抵消冲击力保护了元件安装壳；如图9所示，当顶部冲击力时，顶板将冲击力传导到元件安装壳中，元件安装壳将力传导到后支撑和连接支撑上，连接支撑通过断裂凹槽将力传导到前支撑上，其中后支撑硬度最低，出现断裂，当后支撑断裂后，硬度比后支撑强的连接支撑也因为冲击力作用在断裂凹槽位置处出现弯折且不会断裂，整个元件安装壳向下移动，此时前支撑受力，在U型固定块开口方向处从U型固定块脱离，这样各个元件安装壳在冲击力作用下，一起向下移动且他们之间还会保持一定的间距，从而保护了元件安装壳。当侧板受到撞击时，元件安装壳的保护方法如顶板受到撞击时相同，即后支撑断裂，连接支撑在断裂凹槽处弯折。在电气柜中，通电之间的电气元件通过伸缩电线机构连接通电，在电气柜受到撞击时，元件之间将会发生相对位移，伸缩电线机构 的电线伸缩功能能够保证正常通电。本发明在电气柜增加了后支撑、前支撑、连接支撑，通过将冲击力转移或者使元件安装壳躲避撞击的方法实现了电气柜的抗撞功能，具有较高的实用性。
