Description
技术领域
本发明涉及一种用于测量波长变化的光纤布拉格光栅(FBG)传感器的固定器,FBG传感器通过所述固定器安装在待测物体上,并且在所述固定器内保持FBG传感器的初始设定值,本发明尤其涉及一种具有一对固定件的固定器,所述固定件用于通过紧固螺栓(fasteningbolt)来固定管件,其中FBG传感器插入在所述管件内并固定在固定件上,并且所述管件保持FBG传感器的初始值以及保护FBG传感器。
背景技术
通常,光纤布拉格光栅(FBG)传感器是通过形成周期性地调制光纤玻璃芯线内的折射率,以选择性地对特定波长进行反射的光栅而制造的波长选择器件。
由于用于测量物理量的FBG传感器具有良好的物理特性,例如,其具有固有波长并且不受电磁波的影响,因此FBG传感器取代了传统的应变计(strain gauge)。近年来,FBG传感器的应用领域显著增加。
尽管只有125毫米的很小的直径,但是FBG传感器每单位面积具有大的张力(tension)。因此,由于FBG传感器容易在外部撞击下破裂,所以需要将FBG传感器精细地安装在建筑物或者桥梁上。
另外,FBG传感器应该牢固地安装以具有合适的张力,从而测量正确的值。由于对于FBG传感器来说没有合适的用于民用建筑的光纤,因此有经验的工程师需要在空间-时间(space-time)受限的现场直接设定FBG传感器的值。
这样,虽然FBG传感器具有良好的测量性能,但是由于FBG传感器难于安装和操作,因此在各种工业领域没有得到广泛应用。
同时,FBG传感器是通过粘合剂、或者可选的固定件直接附着在待测物体上的。因此,FBG传感器可能会暴露在例如雨、风、虫子或动物等外部环境中。
暴露在外部环境中的FBG传感器可能会错误地测量应变(strain),因此,它难以稳定地检查民用建筑,并难以维护测量系统。
发明内容
因此,本发明的一个目的是解决现有技术中存在的问题,并且提供一种用于光纤布拉格光栅(FBG)传感器的固定器,任何人不论在什么安装地点都可通过该固定器安装FBG,以使FBG传感器具有精确的值,并且FBG传感器可以被半永久性的固定和保护。
根据本发明的一个方面,提供了一种用于将光纤布拉格光栅(FBG)传感器安装在待测物体上的固定器,以测量物体的波长变化,所述固定器可包括:底面附着在物体上的一对固定件,FBG传感器的两端插入并且通过粘合剂附着在所述固定件内;用于以一定间隔将所述一对固定件隔开的管件,FBG传感器插入到管件的中空部分内以保护FBG传感器免受外部影响;以及用于安装固定件和管件的装置。
附图说明
通过参照附图对本发明的优选实施方案进行描述,本发明的上述目的、其他特征和优点将会更加清楚,在附图中:
图1是根据本发明的一个优选实施方案的用于光纤布拉格光栅(FBG)传感器的固定器的立体图;
图2是图1中的固定器的分解图;
图3是根据本发明的另一个优选实施方案的用于光纤布拉格光栅传感器的固定器的底视图;
图4是图1中的固定器的剖视图。
具体实施方式
以下将对本发明的优选实施方案进行详细说明,附图中示出了这些优选实施方案的实施例。
根据本发明的用于测量待测物体(例如建筑物和桥梁)的应变的光纤布拉格光栅(FBG)传感器S的固定器包括:一对固定件3,其底面附接在物体上,并且FBG传感器S的两端插入并且通过粘合剂F附接在固定件3中;用于以一定间隔将所述一对固定件隔开的管件2,FBG传感器S插入到所述管件的中空部分内以使其不受外部影响;以及用于对固定件3和管件2进行固定的装置。
所述固定装置包括从固定件3的各侧突出的管件接收部分3a,在管件接收部分的上部形成的螺纹孔3d,以及与螺纹孔3d螺纹接合用以压挤和固定管件2的紧固螺栓4。
管件2的两端安装到固定件3之间的管件接收部分3a中。FBG传感器S插入管件2内,并且优选地具有间隙度(degree of clearance),从而使得FBG传感器S不是被限制在固定件3的管件接收部分3a之间。
固定件3具有底面开放以接纳FBG传感器S的传感器保持槽3b,以及用于在传感器保持槽3b的下部选择性地将其打开/关闭的盖子6。
具体地,传感器保持槽3b沿着固定件3的中心部分(FBG传感器S由其通过)形成。传感器保持槽3b填充有粘合剂F,FBG传感器S插入粘合剂F内。这样,FBG传感器S在其两端通过粘合剂固定,并且在FBG传感器上施加了张力。
参照图3,传感器保持槽3b在其内侧至少形成有一个防滑槽3c。在传感器保持槽中填充的粘合剂F硬化的情况下,可以防止由于固定件3和粘合剂F之间的线性膨胀系数不同而在传感器保持槽3b中产生间隙。
举例来说,环氧树脂可用作粘合剂。
如上所述,如果FBG传感器S通过固定件3的传感器保持槽3b牢固地安装,那么固定件3的底面将通过粘合剂牢固地附着在待测物体(未示出)的表面上。
固定件3在其上表面设置有至少一个螺纹通孔3e。当难以将固定件3的底面通过粘合剂附着在待测物体上时,紧固螺栓5通过螺纹孔3e与附着在待测物体上的固定板7螺纹结合,从而将固定件3牢固地安装在待测物体上。如果需要的话,可以通过松开螺栓5来再次使用固定件。
当使用紧固螺栓5和固定板7、或者粘合剂将固定件3牢固地附着在物体的表面上后,通过松开管件接收部分3a(其被安装以保持FBG传感器S的应力)的螺栓4,FBG传感器S的接合状态将会变松或者松脱,从而完成了安装用于FBG传感器(测量待测物体的应变)的固定器1的过程。
如上所述,当FBG传感器S完全安装到物体的表面上时,FBG传感器S将由固定器1的管件2和固定件3安全地保护,以防止其受到诸如风或虫子等外部环境的影响。另外,随着时间的流逝张力是不会变化的,这样就可以正确地测量应变。
当在某一地点直接使用FBG传感器S时,本发明的固定器的使用方法可以根据待测物体的类型或者测量时间而改变。例如,对于小于一年的较短的时期,可以利用粘合剂将固定件3直接附着在物体上。对于大于一年的较长时期,可以利用紧固螺栓5和固定板7将固定件3牢固地附着在物体上。
如上所述,在将固定件3固定到待测物体上之后,优选地去除接合在管件2上部的紧固螺栓4。这是为了更灵敏地将物体的应变传送到FBG传感器S上。根据测试,这时能够测量高至1ms的应变。
虽然在此参照优选实施方案对本发明进行了描述和说明,但是本领域技术人员应该认识到,在不背离本发明的精神和范围的情况下,可以对其进行各种变化和修改。因此本发明涵盖了落入所附权利要求及其等同物范围内的各种变化和修改。
工业应用性
在进行上面的描述后,根据本发明,任何人都可以利用固定器来安装FBG。另外,可以半永久地安装FBG传感器,并可以防止其受外部环境影响。
这样,本发明的固定器可以防止由于外部环境而错误地测量到物体应变。另外,可以连续地测量民用建筑,而不会产生由电磁波所导致的失真。此外,其解决了在每次定期安全检查时都需要安装传统的电应变计所带来的麻烦。
此外,本发明可以降低安装FBG传感器所需的时间和费用。另外,利用本发明还可以测量FBG传感器的固有波长的变化,从而正确地测量物体的应变与初始值之比,从而相对于传统的测量系统更准确地测量民用建筑的老化程度。
