Description

Technical Field

[0001] This application relates to the technical fields of power, photovoltaic and industrial monitoring, and in particular to a fixing device for fixing fiber optic temperature probes. Background Technology

[0002] The background of fiber optic temperature probe mounting devices mainly includes technical requirements, technological advancements, and wide applications. During the construction of power systems, the temperature inside high-voltage switchgear continuously rises, potentially causing safety accidents; therefore, real-time temperature monitoring is necessary. Traditional temperature sensors are susceptible to interference, leading to inaccurate measurements, while fiber optic temperature probes effectively solve this problem. Currently, fiber optic temperature probes are primarily mounted using aviation adhesive, but this method suffers from low stability, resulting in temperature measurement deviations and delays. Therefore, the development of new mounting devices is needed to improve measurement accuracy and stability.

[0003] Most existing fiber optic temperature probe fixing devices cannot be adjusted according to the fiber size, which results in the device being limited in its use and only able to fix a fiber of a certain size, thus having weak applicability. Utility Model Content

[0004] In order to achieve limiting and fixing of fiber optic temperature probes and fibers of different thicknesses, this application provides a fixing device for fixing fiber optic temperature probes.

[0005] The fixing device for fixing fiber optic temperature probes provided in this application adopts the following technical solution:

[0006] A fixing device for fixing a fiber optic temperature probe includes a housing. An inlet hole and an outlet hole are provided on opposite sides of the housing. The fiber optic temperature probe is inserted into the housing through the inlet hole, and the main working part of the fiber optic temperature probe is inserted out of the housing through the outlet hole. An adjustable fiber optic fixing mechanism and an adjustable probe fixing mechanism are arranged sequentially inside the housing along the insertion direction of the fiber optic temperature probe.

[0007] By adopting the above technical solution, after the fiber optic temperature probe is inserted into the housing, it passes through the fiber fixing mechanism and the probe fixing mechanism in sequence to exit the housing. The probe fixing mechanism can fix the fiber optic temperature probe, and by adjusting the probe fixing mechanism, it can be well fixed for fiber optic temperature probes of different sizes. The fiber fixing mechanism can fix the fiber, and by adjusting the fiber fixing mechanism, it can fix the fiber with different thicknesses, making it more versatile.

[0008] Preferably, the probe fixing mechanism includes a sliding assembly, and the output end of the sliding assembly is provided with a first clamping cylinder and a second clamping cylinder, and the fiber optic temperature measuring probe can be clamped and fixed between the first clamping cylinder and the second clamping cylinder.

[0009] By adopting the above technical solution, the distance between the first clamping cylinder and the second clamping cylinder can be adjusted by using the sliding component, so that fiber optic temperature probes of different thicknesses can pass between the first clamping cylinder and the second clamping cylinder. Then, the sliding component is used to bring the first clamping cylinder and the second clamping cylinder closer to each other to achieve clamping of the fiber optic temperature probe.

[0010] Preferably, the sliding assembly includes a groove formed on the inner wall of the housing, in which a first slider and a second slider are slidably connected. The first clamping cylinder is disposed on the first slider, and the second clamping cylinder is disposed on the second slider. The sliding assembly also includes a threaded rod rotatably mounted on the housing. The threaded rod has a first thread and a second thread arranged symmetrically in opposite directions. The first slider has a first threaded hole along its sliding direction that is threadedly engaged with the first thread. The second slider has a second threaded hole along its sliding direction that is threadedly engaged with the second thread. The end of the threaded rod is also fixedly connected to a second knob, which is located on the outside of the housing.

[0011] By adopting the above technical solution, rotating the second knob can drive the threaded rod to rotate, thereby driving the first slider and the second slider to move closer or further away, and thus driving the first clamping cylinder and the second clamping cylinder to move along with the movement of the first slider and the second slider.

[0012] Preferably, the probe fixing mechanism further includes an adjustment assembly; the adjustment assembly includes a meshing first gear and a second gear, and a drive rod rotatably mounted on the housing; the first clamping cylinder is rotatably mounted on the first slider, and the second clamping cylinder is rotatably mounted on the second slider; the first gear is fixedly mounted on the first clamping cylinder, the second gear is fixedly mounted on the second clamping cylinder, one end of the drive rod is fixedly mounted at the rotation center of the first gear or the second gear, and the other end of the drive rod is located on the outside of the housing and a third knob is fixedly mounted thereon.

[0013] By adopting the above technical solution, after the fiber optic temperature probe is clamped between the first clamping cylinder and the second clamping cylinder, the third knob is rotated to drive the drive rod to rotate, thereby driving the first gear and the first clamping cylinder to rotate. Then, the first gear drives the second gear, which is meshed with the outer wall of the first gear, to rotate in the opposite direction, thereby driving the second clamping cylinder to rotate with the second gear. This allows the position of the fiber optic temperature probe to be adjusted, thereby adjusting the position of the fiber to facilitate the fiber fixing mechanism to limit the fiber.

[0014] Preferably, the optical fiber fixing mechanism includes a fixing rod, one end of which is fixedly connected to the inner wall of the housing, and the other end of which is fixedly connected to a coil through which the optical fiber temperature probe and the optical fiber pass; a winding rod is also rotatably passed through the fixing rod, and the winding rod is rotatably connected to the housing, the other end of the coil is fixedly connected to the winding rod, and the end of the winding rod away from the fixing rod is located on the outside of the housing and fixedly connected to a first knob.

[0015] By adopting the above technical solution, before fixing the fiber optic temperature probe, first turn the first knob to increase the overall diameter of the coil, facilitating the insertion of fiber optic temperature probes of different sizes. After the fiber optic temperature probe enters the housing through the inlet hole, passes through the coil, and exits through the outlet hole via the probe fixing mechanism, the first knob is then turned to rotate the winding rod, causing the coil to wind around the rod. When the coil is wound to a suitable length and the fiber is fixed, the first knob is stopped. By adjusting the overall diameter of the coil, it is possible to easily pass through fiber optic probes of different thicknesses and achieve good fixing results for fibers of different thicknesses.

[0016] Preferably, multiple fixing rods are provided, and multiple coils are arranged sequentially along the insertion direction of the fiber optic temperature probe. The winding rod passes through multiple fixing rods and is rotatably connected to the fixing rods.

[0017] By adopting the above technical solution and setting multiple coils, the fixation effect of the optical fiber can be improved.

[0018] Preferably, the outer side of the housing is provided with limit components corresponding to the first knob, the second knob and the third knob.

[0019] By adopting the above technical solution, the limiting component can be used to conveniently limit the first, second, and third knobs after adjustment, thereby ensuring the fixation effect of the fiber optic temperature probe and the fiber.

[0020] Preferably, the limiting component includes a fixing block fixedly connected to the outer wall of the housing, and the three fixing blocks are respectively located near the first knob, the second knob, and the third knob; a sliding groove is provided on the fixing block, and a limiting block is slidably connected in the sliding groove, and one end of the limiting block is connected to the bottom of the sliding groove through an elastic element, and the other end of the limiting block is used to abut against the first knob, the second knob, and the third knob, and the elastic element is in a compressed state.

[0021] By adopting the above technical solution, when no adjustment is needed for the fiber optic fixing mechanism and the probe fixing mechanism, the elastic force of the elastic element can always keep the limiting block against the first knob, the second knob, and the third knob, thereby limiting the first knob, the second knob, and the third knob respectively; when the fiber optic fixing mechanism and the probe fixing mechanism need to be adjusted, the limiting block is pushed away from the first knob, the second knob, and the third knob that need to be adjusted by compressing the elastic element, thereby enabling the corresponding adjustment.

[0022] Preferably, an elastic washer is fixedly connected to the outer wall of the housing at the position corresponding to the outlet hole, and the elastic washer is used to be sleeved on the outside of the fiber optic temperature probe.

[0023] By adopting the above technical solution, the elastic washer can be used to fix the fiber optic temperature probe.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. A probe fixing structure is adopted. The distance between the first and second clamping cylinders can be adjusted by rotating the second adjustment knob, so that the optical fiber probes of different thicknesses can be fixed well. Furthermore, by rotating the third knob, the first and second clamping cylinders can be rotated in opposite directions, thereby adjusting the position of the clamped probe and thus the position of the optical fiber.

[0026] 2. The fiber optic fixing structure allows for the loosening of the coil by rotating the first knob, enabling fiber optic probes of different thicknesses to pass through the coil to the probe fixing structure; then, rotating the first knob tightens the coil, thus enabling fixing of fiber optics of different thicknesses and making it more versatile.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a fixing device for fixing a fiber optic temperature probe.

[0036] Reference Figures 1 to 6 A fixing device for fixing a fiber optic temperature probe includes a housing 1, which is generally rectangular in shape. Two opposite sides along the length of the housing 1 are symmetrically provided with an inlet hole 11 and an outlet hole 12. The fiber optic temperature probe is inserted into the housing 1 through the inlet hole 11, and then the main working part of the probe exits through the outlet hole 12. An adjustable fiber optic fixing mechanism 2 and a probe fixing mechanism 3 are sequentially arranged inside the housing 1 along the insertion direction of the fiber optic temperature probe. Adjustment of the probe fixing mechanism 3 allows for fixing fiber optic temperature probes of different sizes, and adjustment of the fiber optic fixing mechanism 2 allows for fixing fiber optic cables of different sizes.

[0037] The fiber optic fixing mechanism 2 includes two fixing rods 21 located inside the housing 1, near the inlet hole 11. Each fixing rod 21 is cylindrical, and its length is perpendicular to the length of the housing 1. One end of each fixing rod 21 is perpendicularly connected to a side wall of the housing 1 along its length, while the other end of each fixing rod 21 is fixedly connected to a coil 22 for mounting the fiber optic cable. A through hole is formed at the end of each fixing rod 21 with the coil 22 along the length of the housing 1. A winding rod 23 is rotatably connected within the through hole. The winding rod 23 is cylindrical, and its length is perpendicular to the length of the fixing rod 21. One end of the winding rod 23 rotatably passes through the two through holes, while the other end of the winding rod 23 is located on the outside of the housing 1 and connected to a first knob 24. One end of the coil 22 is fixedly connected to the end face of the fixing rod 21, and the other end of the coil 22 is fixedly connected to the winding rod 23. When the winding rod 23 is rotated under force, it can drive the coil 22 to be wound on the winding rod 23 or drive the coil 22 to be wound away from the winding rod 23.

[0038] Before fixing the fiber optic temperature probe, first rotate the first knob 24 to increase the overall diameter of the coil 22, facilitating the insertion of fiber optic temperature probes of different sizes. After the fiber optic temperature probe enters the housing 1 through the inlet hole 11, it passes through the two coils 22 in sequence and exits through the outlet hole 12 via the probe fixing mechanism 3. Then, rotate the first knob 24 to rotate the winding rod 23, causing the coil 22 to wind around the winding rod 23. When the coil 22 is wound to a suitable length and the fiber is fixed, stop rotating the first knob 24. By adjusting the overall diameter of the coil 22, it is possible to easily pass through fiber optic detection probes of different thicknesses and achieve good fixing effects for fibers of different thicknesses. Preferably, the coil 22 is made of materials with a certain degree of elastic deformation, such as rubber or silicone, to protect the fiber.

[0039] The probe fixing mechanism 3 includes a sliding component 31 and an adjusting component 34. The output end of the sliding component 31 is provided with a first clamping cylinder 32 and a second clamping cylinder 33. By adjusting the sliding component 31, the fiber optic temperature measuring probe can be clamped and fixed between the first clamping cylinder 32 and the second clamping cylinder 33. The adjusting component 34 is provided on the first clamping cylinder 32 and the second clamping cylinder 33. The adjusting component 34 is used to adjust the position of the fiber optic temperature measuring probe after clamping, so that the fiber optic temperature measuring probe can accurately pass through the outlet hole 12.

[0040] The sliding assembly 31 includes a groove 311 formed on the inner wall of the housing 1, within which a first slider 312 and a second slider 313 are slidably connected. The groove 311 is formed on the longitudinal plane of the housing 1, and its longitudinal direction is perpendicular to that of the housing 1. The drive assembly also includes a threaded rod 314 rotatably connected to the housing 1, with its longitudinal direction parallel to that of the groove 311. The threaded rod 314 has a first thread and a second thread symmetrically arranged in opposite directions along its own longitudinal direction. The first slider 312 has a first threaded hole along its own sliding direction that engages with the first thread, and the second slider 313 has a second threaded hole along its own sliding direction that engages with the second thread. Rotating the threaded rod 314 causes the first slider 312 and the second slider 313 to move closer or further apart. A second knob 315 is also fixedly connected to the end of the threaded rod 314, and the second knob 315 is located on the outside of the housing 1 to facilitate rotation of the threaded rod 314.

[0041] The first clamping cylinder 32 and the second clamping cylinder 33 are cylindrical in shape, and their axes are perpendicular to their sliding direction. The first clamping cylinder 32 is rotatably mounted on the side of the first slider 312 away from the slide groove 311, and the second rotating cylinder is fixedly mounted on the side of the second slider 313 away from the slide groove 311. The optical fiber can be clamped between the first clamping cylinder 32 and the second clamping cylinder 33.

[0042] The adjusting assembly 34 includes a first gear 341, a second gear 342, and a drive rod 343, with the first gear 341 and the second gear 342 meshing. The first gear 341 is fixedly connected to the side of the first clamping cylinder 32 away from the slide groove 311, and the second gear 342 is fixedly connected to the side of the second clamping cylinder 33 away from the slide groove 311. The drive rod 343 is generally cylindrical, and its central axis coincides with the axis of the first gear 341. The drive rod 343 is rotatably connected to the housing 1, with one end of the drive rod 343 fixedly connected to the center of the first gear 341, and the other end of the drive rod 343 located on the outside of the housing 1 and fixedly mounted with a third knob 344.

[0043] After the fiber optic temperature probe is clamped between the first clamping cylinder 32 and the second clamping cylinder 33 by rotating the threaded rod 314, the third knob 344 is then rotated to drive the drive rod 343 to rotate, thereby driving the first gear 341 and the first clamping cylinder 32 to rotate. Then, the first gear 341 drives the second gear 342, which is meshed with the outer wall of the first gear 341, to rotate in the opposite direction, thereby driving the second clamping cylinder 33 to rotate with the second gear 342. This allows the position of the fiber optic temperature probe to be adjusted, and thus the position of the fiber optic cable to be adjusted.

[0044] Furthermore, this embodiment of the application also includes three limiting components 4 disposed on the outer wall of the housing 1. Each limiting component 4 includes a fixing block 41 fixedly connected to the outer wall of the housing 1, and the three fixing blocks 41 are respectively disposed near the first knob 24, the second knob 315, and the third knob 344. A sliding groove 42 is provided on the side of the fixing block 41 near the knob, and a limiting block 43 is slidably connected in the sliding groove 42. One end of the limiting block 43 is connected to the bottom of the sliding groove 42 through an elastic member 44, and the other end of the limiting block 43 is used to abut against the first knob 24, the second knob 315, and the third knob 344. The elastic member 44 is always in a compressed state, so that the elastic force of the elastic member 44 can drive the limiting block 43 to abut against the outer wall of the first knob 24, the second knob 315, and the third knob 344, thereby restricting the rotation of the first knob 24, the second knob 315, and the third knob 344, thereby fixing the position of the winding rod 23 and stabilizing the diameter of the coil 22. When it is necessary to rotate the first knob 24, the second knob 315, and the third knob 344, the limiting block 43 is pushed to further compress the elastic element 44. Preferably, the end of the limiting block 43 that contacts the first knob 24, the second knob 315, and the third knob 344 is provided with a friction pad, thereby improving the limiting effect on the knobs.

[0045] Preferably, an elastic washer 13 is fixedly connected to the outer wall of the housing 1 at the position corresponding to the wire outlet hole 12. The elastic washer 13 is used to be sleeved on the outside of the fiber optic temperature probe, so as to fix the fiber optic temperature probe.

[0046] The implementation principle of a fixing device for fixing a fiber optic temperature probe in this application embodiment is as follows: before fixing the fiber optic temperature probe, the limiting component 4 is adjusted so that the first knob 24, the second knob 315 and the third knob 344 can all rotate. When fixing the fiber optic temperature probe, firstly, the fiber optic temperature probe is inserted into the housing 1 through the inlet hole 11, then passes through two coils 22 in sequence, and enters between the first clamping cylinder 32 and the second clamping cylinder 33, before exiting through the outlet hole 12 to the outside of the housing 1. Next, by rotating the second knob 315, the threaded rod 314 is rotated, causing the first clamping cylinder 32 and the second clamping cylinder 33 to move closer together and clamp the fiber optic temperature probe. Then, by rotating the third knob 344, the drive rod 343 is rotated, causing the first clamping cylinder 32 and the second clamping cylinder 33 to rotate in opposite directions, thereby adjusting the position of the fiber optic cable. Afterward, by rotating the first knob 24, the winding rod 23 is rotated, causing the coil 22 to tighten, thus fixing the fiber optic cable. Finally, the limiting assembly 4 is adjusted again to limit the movement of the first knob 24, the second knob 315, and the third knob 344. This structure allows for the limiting and fixing of fiber optic temperature probes and fibers of different thicknesses.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
