It should be noted that, in the embodiment of the present application, the first bottom wall may be a plane, an arc surface, or the like, and the second bottom wall may also be a plane, an arc surface, or the like.

FIG. 2 is a schematic view of another optical fiber sensor fixing device provided in an embodiment of the present application; fig. 3 is a schematic structural view of the optical fiber sensor fixing device shown in fig. 2. Referring to fig. 2 and 3, based on any one of the fiber sensor fixing devices provided in the embodiments of the present application, the fiber sensor fixing device 100 may include a first side wall 130 and a second side wall 140 facing away from each other, and the groove 110 may extend from the first side wall 130 to the second side wall 140. That is, in the embodiment of the present application, the groove 110 may penetrate the first and second sidewalls 130 and 140 in the extending direction thereof.

Referring to fig. 2, optionally, in an embodiment of the present application, the optical fiber sensor fixture 100 may further include a third sidewall 150 located between the first sidewall 130 and the second sidewall 140. The notch portion 1101 may include an opening 1101a, and the opening 1101a may be provided to the third sidewall 150.

It should be noted that, in the embodiment of the present application, the opening 1101a may not be provided, and only the groove 110 may penetrate through the first sidewall 130 and the second sidewall 140 along the extending direction of the groove 110, and in the embodiment of the present application, the optical fiber 200 may be inserted into the groove 110 through the extending direction of the groove 110. After fiber 200 is threaded into groove 110, fiber 200 can be caused to snap into groove bottom 1102.

Referring to FIG. 3, optionally, in an embodiment of the present application, the optical fiber sensor fixture 100 may further include a fourth sidewall 160 facing away from the third sidewall 150, and the fourth sidewall 160 may be provided with an arc-shaped slot 1601.

FIG. 4 is a schematic view of an optical fiber sensor fixing device and an object to be tested according to an embodiment of the present disclosure; it shows the case where the optical fiber sensor fixing device is provided on the object to be tested, and the optical fiber of the optical fiber sensor is provided on the optical fiber sensor fixing device. Referring to fig. 4, in the embodiment of the present application, when the object 300 is a cylindrical structure, if the arc-shaped groove 1601 is disposed on the fourth sidewall 160 of the optical fiber sensor fixing device 100, the arc-shaped groove 1601 can be attached to the surface of the object 300.

For example, in the embodiment of the present application, the object 300 to be tested may be a furnace tube of a utility boiler, and the optical fiber sensor may be an optical fiber temperature sensor, so that the arc-shaped groove 1601 of the optical fiber sensor fixing device 100 may be combined with the furnace tube of the utility boiler, and the optical fiber sensor fixing device 100 may be fixed on the furnace tube of the utility boiler by welding. The fiber of the fiber optic temperature sensor may be clamped in the groove bottom 1102 and the temperature of the fiber optic sensor holder 100 may be detected by a grating point (i.e., temperature sensing point) provided on the fiber. Because the optical fiber sensor fixing device 100 is welded on the furnace tube, the temperature of the optical fiber sensor fixing device 100 is substantially the same as the temperature of the furnace tube, so that the approximate temperature of the furnace tube can be determined according to the temperature of the optical fiber sensor fixing device 100 measured by the optical fiber temperature sensor. In this way, the temperature of the test object 300 can be tested.

FIG. 5 is a schematic view of another optical fiber sensor fixing device and an object to be tested according to an embodiment of the present application; it shows the case where the optical fiber sensor fixing device is provided on the object to be tested, and the optical fiber of the optical fiber sensor is provided on the optical fiber sensor fixing device. Referring to fig. 5, in the above example, the utility boiler may include a plurality of columns arranged side by side, and the number of the optical fiber sensor fixing devices 100 may correspond to the number of the columns, and the optical fiber sensor fixing devices 100 may be fixed to one column in a one-to-one correspondence. Alternatively, each of the fiber sensor fixtures 100 may be disposed at the corresponding pipe string in the same attitude and height. Further, a plurality of grating points may be disposed at intervals on the optical fiber of the optical fiber sensor, and the intervals of the grating points may be consistent with the intervals of the optical fiber sensor fixing device 100. In this way, each grating point can be mated to one fiber sensor fixture 100. Thus, the temperature of each column can be tested by a single fiber sensor provided in each fiber sensor fixture 100.

It should be noted that, in the embodiment of the present application, the optical fiber sensor fixing device 100 may be welded on the object 300 to be tested, or may be disposed on the object 300 to be tested by means of adhesion, clamping, binding, and the like, which are not listed here.

It should be noted that, in the embodiment of the present application, the surface of the object 300 to be tested may also be a plane, and if the surface of the object 300 to be tested is a plane, the arc-shaped groove 1601 may not be provided.

Alternatively, referring to fig. 2, in an embodiment of the present application, the groove 110 may be obliquely disposed. Thus, the length of the groove 110 is longer than a horizontal groove, so that the contact area between the optical fiber 200 and the groove bottom 1102 of the groove 110 can be increased, the friction force applied to the optical fiber 200 can be increased, and the optical fiber 200 can be firmly mounted on the groove bottom 1102.

If the inclination amount of the groove 110 is too large, the bending angle of the optical fiber 200 is likely to be too large, and the optical fiber 200 is likely to be damaged due to the too large bending angle. Therefore, alternatively, in the embodiment of the present application, the extending direction of the groove 110 may be at an angle of 6 to 17 degrees to the horizontal plane.

Alternatively, in the embodiment of the present application, if the optical fiber sensor is an optical fiber temperature sensor, the optical fiber sensor fixing device 100 may be made of a material having better thermal conductivity. Illustratively, the optical fiber sensor fixture 100 may be a metal block. Of course, in the embodiments of the present application, the optical fiber sensor may also be other types of sensors, such as an optical fiber pressure sensor, etc., which are not listed here. In the embodiment of the present application, a person skilled in the art may also flexibly set the material of the optical fiber sensor fixing device 100 according to actual requirements.

Referring to fig. 1, alternatively, in an embodiment of the present application, the optical fiber sensor fixing device 100 may have a rectangular parallelepiped configuration. Thus, when the optical fiber sensor fixing device 100 has a rectangular parallelepiped structure, the blank of the optical fiber sensor fixing device 100 has a regular shape, which facilitates clamping the blank in the process of processing the groove 110 by using the blank. Of course, in other embodiments of the present application, the optical fiber sensor fixing device 100 may also have a cylindrical structure, a quadrangular prism structure, a pentagonal prism structure, etc., which are not listed here.

In this way, in the embodiment of the present application, when the optical fiber 200 of the optical fiber sensor needs to be installed, the optical fiber sensor fixing device 100 may be fixed at a target position, the optical fiber 200 of the optical fiber sensor may enter the groove 110 through the notch portion 1101, and the optical fiber 200 may be clamped in the groove bottom 1102, so that the installation of the optical fiber 200 of the optical fiber sensor may be achieved. When the optical fiber 200 of the optical fiber sensor is detached, the optical fiber 200 may be lifted up, and the optical fiber 200 may be detached from the groove 110 through the notch portion 1101. In the process of assembling and disassembling the optical fiber 200 of the optical fiber sensor, external tools such as a screwdriver and a wrench are not needed, so that the optical fiber 200 of the optical fiber sensor can be assembled and disassembled conveniently.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
