一种外浮顶罐光纤光栅安装卡具
摘要：
本发明涉及油气管道领域，公开了一种外浮顶罐光纤光栅安装卡具，以解决现有技术中光纤光栅感温火灾报警系统在外浮顶罐安装不牢固的技术问题。该卡具包括：支架，所述支架包括第一结构、第二结构和第三结构，所述第一结构和所述第三结构设置于所述第二结构两侧，且所述第一结构与所述第三结构相对；骑马螺栓，所述骑马螺栓两端的螺纹穿过所述第一结构；减振垫片，设置于所述骑马螺栓的槽内，所述减振垫片上部设置有开口，光纤光栅通过所述开口放置于所述减振垫片内部；紧固螺母，紧固于所述骑马螺栓的螺纹；安装螺孔，设置于第三结构，通过所述安装螺孔将所述卡具固定于一固定件。达到了将光纤光栅感温火灾报警系统牢固安装在外浮顶罐的技术效果。
摘要（英）：

The invention relates to the field of oil-gas pipelines, and discloses a fixture for installation of a fiber bragg grating on an outer floater. By means of the fixture, the technical problem that the installation of a fiber bragg grating temperature-sensing fire alarm system on the outer floater is unstable in the prior art is solved. The fixture comprises a support, a u-bolt, a vibration-damping spacer, fastening nuts and an installing screw hole. The support comprises a first structure, a second structure and a third structure. The first structure and the third structure are arranged on the two sides of the second structure, and the first structure is opposite to the third structure. Threads at the two ends of the u-bolt penetrate through the first structure. The vibration-damping spacer is arranged in a groove of the u-bolt. An opening is formed in the upper portion of the vibration-damping spacer. The fiber bragg grating is placed inside the vibration-damping spacer through the opening. The fastening nuts are fastened on the threads of the u-bolt. The installing screw hole is formed in the third structure, and the fixture is fixed to a fixing piece through the installing screw hole. The technical effect that the fiber bragg grating temperature-sensing fire alarm system is firmly installed on the outer floater is achieved.
