[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] On the one hand, please refer to Figures 1 to 4 This embodiment provides a sensor fixing device, which includes a clamping member 1 and a base 2. The base 2 is detachably connected to the clamping member 1. The base 2 and the clamping member 1 are used to hold the pipe 3 to be tested. The base 2 is used to install a sensor 4, and the probe 41 of the sensor 4 can abut against the pipe 3 to be tested. With this configuration, the detachable connection between the base 2 and the clamping member 1 allows the base 2 and the clamping member 1 to be placed in the installation position and then connected. When installing this sensor fixing device, interference between it and other components can be avoided, facilitating flexible arrangement in various installation spaces.

[0030] Alternatively, please refer to Figures 1 to 3 The base 2 has a support surface 21. The clamping member 1 includes an elastic sheet 12, a pressing sheet 13, and an operating sheet 14. The pressing sheet 13 is connected between the elastic sheet 12 and the operating sheet 14. The pressing sheet 13 is used to press the pipe to be tested onto the support surface 21. The elastic sheet 12 can undergo elastic deformation. When the operating sheet 14 is subjected to external force, the operating sheet 14 can drive the pressing sheet 13 away from the support surface 21. With this configuration, the pipe to be tested can be quickly clamped between the clamping member 1 and the base 2 and pressed onto the support surface 21 through the operating sheet 14, improving work efficiency.

[0031] Alternatively, please refer to Figure 3 The clamping plate 13 has a first end and a second end. The first end is connected to the elastic plate 12, and the second end is connected to the operating plate 14. The clamping plate 13 has a first state in which the pipe to be tested 3 is pressed against the support surface 21, and a second state in which it is suspended. When the clamping plate 13 is in the second state, the clamping plate 13 is tilted, and the second end of the clamping plate 13 is closer to the base 2 than the first end. With this configuration, when the clamping plate 13 is in the first state, the clamping plate 13 can still maintain the second end being closer to the base 2 than the first end, and a reduced outlet is formed between the base 2 and the clamping member 1, preventing the pipe to be tested 3 from coming loose from between the base 2 and the clamping member 1.

[0032] Alternatively, please refer to Figure 2 A flared opening 6 is formed between the operating plate 14 and the outer side of the base 2, allowing the pipe to be tested 3 to enter between the clamping member 1 and the base 2 through the flared opening 6. This configuration creates a gradually widening opening between the operating plate 14 and the outer side of the base 2, making it easier to insert and remove the pipe to be tested 3. Simultaneously, the smooth transition of the flared opening 6 reduces the risk of scratches or damage to the pipe to be tested 3 during insertion.

[0033] Alternatively, please refer to Figure 1 and Figure 3The elastic sheet 12 has multiple perforated holes 15 spaced apart. This arrangement avoids the risk of damage caused by localized stress concentration on the elastic sheet 12, thereby achieving a more uniform stress distribution under high pressure or vibration environments and extending the service life of the device. Simultaneously, the perforated holes 15 reduce the mass of the elastic sheet 12, reducing the load on the pipe 3 when the sensor fixing device is clamped onto it, and mitigating the potential impact of excessive weight on the operation of the pipe 3.

[0034] Alternatively, please refer to Figure 2 and Figure 3 The elastic plate 12 is arc-shaped, and the central angle of the elastic plate 12 is greater than 180 degrees. This design helps to distribute the stress more evenly, reduce stress concentration, thereby reducing the risk of material fatigue and fracture, and extending the service life of the device; the central angle of more than 180 degrees allows the elastic plate 12 to provide a larger angle of bending deformation to adapt to the test pipe 3 of different diameters.

[0035] Alternatively, please refer to Figure 2 The base 2 has a through hole 22, the wall of which is used for sliding engagement with the sensor 4. When the clamping member 1 presses the pipe 3 to be tested against the support surface 21 of the base 2, the pipe 3 can press the sensor 4 against the base 2. This configuration allows the sensor 4 to be pressed against the base 2 by the pipe 3, thus fixing and abutting against it, ensuring that the probe 41 of the sensor 4 is stably fixed to the surface of the pipe 3, guaranteeing the accuracy of the measurement results.

[0036] Specifically, the longitudinal section of the through hole 22 is T-shaped, having a large hole and a small hole. The sensor 4 includes a probe 41 and a sensor 4 body, which are T-shaped. The probe 41 of the sensor 4 is accommodated in the large hole, and the sensor 4 body is accommodated in the small hole, thereby achieving axial positioning of the sensor 4. In other embodiments, the sensor 4 can also be fixed to the base 2 by fastening bolts.

[0037] Alternatively, please refer to Figure 2 and Figure 3 The clamping component 1 also includes a connecting piece 11, an elastic piece 12 connected between the connecting piece 11 and the clamping piece 13, and a plurality of first fastening holes 23 provided on the base 2. The sensor fixing device also includes a plurality of fasteners 5, which can pass through the connecting piece 11 and are screwed into the plurality of first fastening holes 23 one by one. This arrangement allows the clamping component 1 and the base 2 to be detachably connected. When installing the sensor fixing device, the clamping component 1 and the base 2 can be placed on both sides of the pipe 3 to be tested and then connected, avoiding interference with other components and facilitating flexible arrangement in various installation spaces.

[0038] Alternatively, please refer to Figure 2 The base 2 is also provided with multiple second fastening holes 24. The axis of each second fastening hole 24 is parallel to the axis of each first fastening hole 23, and the first fastening holes 23 and the second fastening holes 24 are located on opposite sides of the sensor 4. Multiple fasteners 5 can also pass through the connecting piece 11 and be screwed into the multiple second fastening holes 24 one by one. With this configuration, when the installation space is small and there is interference between screwing fasteners 5 into the first fastening holes 23 and the second fastening holes 24, the other fastener 5 can be screwed into the other fastening hole 23 or the other fastening hole 24, increasing the flexibility of the device.

[0039] On the other hand, please refer to Figure 4 This embodiment provides a pipeline vibration measurement structure, which includes a pipeline 3 to be measured, a sensor 4, and the aforementioned sensor fixing device. The pipeline 3 to be measured is held between the base 2 and the clamping member 1, and the probe 41 of the sensor 4 abuts against the pipeline 3 to be measured. Specifically, the pipeline 3 to be measured in this pipeline vibration measurement structure is a small branch pipe. The small branch pipe can be quickly and stably fixed on the sensor fixing device, improving the ease of operation and the accuracy of the measurement results during the vibration measurement process.
