Fiber bragg grating settling sensor
The invention provides a fiber bragg grating settling sensor, and belongs to the technical field of soil monitoring sensing. The sensor comprises a first pipe body, a second pipe body mounted outsidethe first pipe body in a sleeving manner, an elastic part mounted in the first pipe body and a rigid element arranged on the top of the first pipe body in an erecting manner, the bottom of the first pipe body is closed, the first pipe body and the second pipe body are in clearance fit, a stress part which is used for being in contact with a measured soil layer and bearing the down force of the measured soil layer is arranged on the outer wall of the second pipe body, the bottom of the elastic part is connected with the bottom of the first pipe body, the top of the elastic part extends to the outside of the first pipe body or is flush with the top end of the first pipe body, a fiber bragg grating used for monitoring the extension amount of the elastic part is arranged on the elastic part inan attaching manner, one end of the rigid element is connected with the top end of the elastic part, and the other end of the rigid element is connected with the top end of the second pipe body. Thefiber bragg grating settling sensor is precise in measuring result, simple in structure, rapid and convenient to mount, convenient to maintain, and convenient to carry and move.
本发明提供了一种光纤光栅沉降传感器，属于土体监测传感技术领域，包括第一管体、套设在第一管体外的第二管体、设置在第一管体内的弹性件，以及搭设于第一管体的顶部的刚性元件；第一管体的底部封闭；第二管体与第一管体间隙配合；第二管体的外壁上设置有用于与被测土层接触并承受被测土层下压力的受力部；弹性件的底部与第一管体的底部连接，顶部延伸至第一管体外或与第一管体的顶端齐平；弹性件上贴设有用于监测弹性件伸长量的光纤光栅；刚性元件的一端与弹性件的顶端连接，另一端与第二管体的顶端连接。本发明提供的光纤光栅沉降传感器，测量结果精确，结构简单，安装便捷，维修方便，且便于携带和移动。
