Description

Technical Field

[0001] The present application relates to the technical field of liquid metering, and more particularly, to an ultrasonic transducer fixing device, an ultrasonic transducer fixing device assembly, and a quick-install external ultrasonic flow measurement device. Background Art

[0002] In the field of liquid metering in industries such as urban water supply and drainage, petroleum, chemical industry, pharmaceuticals, metallurgy, and power, the ultrasonic time-difference method (Time-of-Flight Diffraction, TOFD) is a commonly used means for liquid metering. The ultrasonic time-difference method is a non-destructive testing technology that can calculate the flow rate of a liquid by measuring the time difference between the forward and reverse propagation of ultrasonic waves in the liquid.

[0003] Ultrasonic time-difference liquid metering devices usually have transducers installed in pairs upstream and downstream of the pipeline to be measured. Without changing the structure of the pipeline to be measured itself and without affecting the operation of the liquid inside the pipeline to be measured, the transducers can be installed on the outside of the pipeline to be measured by the external attachment method. The paired transducers are attached to the outer walls on the upstream and downstream sides of the pipeline to be measured, and transmit and receive ultrasonic signals to each other to complete the measurement of the flow rate of the liquid in the pipeline.

[0004] However, the inventors of the present application have found the following problems. When the external environment of the pipeline to be measured is relatively harsh, the ultrasonic transducers are directly exposed to the harsh external environment and are likely to be damaged or have their performance degraded due to high temperature, low temperature, high humidity, electromagnetic interference, etc. in the harsh external environment. In addition, the paired ultrasonic transducers installed manually are prone to axial or circumferential position deviations due to the installation experience of the installers and the regularity of the outer surface of the pipeline to be measured, resulting in inaccurate ultrasonic positioning. When multiple channels need to be measured simultaneously, the consistency of multiple pairs of installed ultrasonic transducers is affected by the experience of the installers; and installing ultrasonic transducers one by one is time-consuming and laborious.

[0005] The content in the background art section is only the technology known to the applicant and does not necessarily represent the prior art in this field. Summary of the Invention

[0006] The present application aims to provide an ultrasonic transducer fixing device to solve at least one of the above technical problems.

[0007] According to one aspect of the present application, the present application provides an ultrasonic transducer fixing device, including a lower fixing part and an upper fixing part. A receiving space is formed at the center of the lower fixing part to receive the bottom of the ultrasonic transducer, so that the bottom of the ultrasonic transducer contacts the object to be measured. Among them, the receiving space can accommodate the bottoms of at least two ultrasonic transducers. The lower end of the upper fixing part is an opening, and the middle part is a cavity for accommodating the body of the ultrasonic transducer. The cavity can accommodate the bodies of at least two ultrasonic transducers. The upper fixing part and the lower fixing part are detachably connected. When the upper fixing part and the lower fixing part are connected, the body of the ultrasonic transducer is completely placed in the cavity of the upper fixing part. And the ultrasonic transducer is fixed by the upper fixing part and the lower fixing part.

[0008] Optionally, a partition is provided in the receiving space. The partition divides the receiving space into a first receiving space and a second receiving space. The first receiving space matches the shape of the bottom of the ultrasonic transducer so that the bottom of the ultrasonic transducer is received in the first receiving space. The second receiving space is for the bottom of the ultrasonic transducer to slide in the second receiving space.

[0009] Optionally, the lower fixing part is provided with a ranging part to provide the distance information between the first ultrasonic transducer and the second ultrasonic transducer.

[0012] Optionally, the upper fixing part is provided with a screw hole. The lower fixing part is provided with a thread. The upper fixing part and the lower fixing part are fixed by matching the screw hole and the thread.

[0013] According to another aspect of the present application, the present application further provides an ultrasonic transducer fixing device assembly, including at least two of the above-mentioned ultrasonic transducer fixing devices.

[0014] According to another aspect of the present application, the present application further provides a quick-install external ultrasonic flow measurement device, including the above-mentioned ultrasonic transducer fixing device.

[0015] Beneficial effects

[0016] The cavity of the upper fixing part and the accommodating space of the lower fixing part fix and seal the ultrasonic transducer, preventing the ultrasonic transducer from being directly exposed to the external environment. As a result, the influence of high temperature, low temperature, high humidity, and electromagnetic interference in the external environment on the ultrasonic transducer is reduced, and the probability of damage or performance degradation of the ultrasonic transducer is decreased. At least two ultrasonic transducers are uniformly installed inside the ultrasonic transducer fixing device. The upper fixing part and the lower fixing part limit the positions of at least two ultrasonic transducers, reducing the axial or circumferential position deviation of the ultrasonic transducers, and thus improving the accuracy of ultrasonic positioning. At least two ultrasonic transducers are uniformly installed and disassembled, simplifying the operation steps. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of this application, rather than all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0028] This application will be described in detail below in conjunction with the drawings of the specification.

[0029] Figure 1 A schematic structural diagram of an ultrasonic transducer fixing device according to an embodiment of this application is shown. According to an exemplary embodiment, as Figure 1 shown, the ultrasonic transducer fixing device includes a lower fixing part 2 and an upper fixing part 1. For example, the upper fixing part 1 and the lower fixing part 2 may be made of materials with good stability and high temperature resistance, such as metal materials, including but not limited to aluminum, iron, stainless steel, etc.

[0030] A receiving space is formed at the center of the lower fixing part 2 to receive the bottom of the ultrasonic transducer 4, so that when the ultrasonic transducer fixing device is installed on the object to be measured, the bottom of the ultrasonic transducer can contact the object to be measured. The receiving space can receive the bottoms of at least two ultrasonic transducers 4. For example, the shape of the receiving space matches the shape of the bottom of the ultrasonic transducer 4. For example, when the ultrasonic transducer 4 is placed in the receiving space of the lower fixing part 2, it can contact the object to be measured.

[0031] The lower end of the upper fixing part 1 is open, and the middle part is a cavity 14 for accommodating the body of the ultrasonic transducer 4. The cavity 14 can accommodate at least two bodies of the ultrasonic transducers 4.

[0032] The upper fixing part 1 and the lower fixing part 2 are detachably connected. For example, the detachable connection mode between the upper fixing part 1 and the lower fixing part 2 can be snap connection. By providing snap structures on the upper fixing part 1 and the lower fixing part 2 that can snap together, the upper fixing part 1 and the lower fixing part 2 are detachably connected.

[0033] Also for example, the detachable connection mode between the upper fixing part 1 and the lower fixing part 2 can also be threaded connection. The upper fixing part 1 is provided with a threaded hole 7. The lower fixing part 2 is provided with a thread 8. The upper fixing part 1 and the lower fixing part 2 are detachably connected through the threaded hole 7 and the thread 8 and in cooperation with a bolt.

[0034] When the upper fixing part 1 and the lower fixing part 2 are connected, the body of the ultrasonic transducer 4 is completely placed inside the cavity 14 of the upper fixing part 1. And the ultrasonic transducer 4 is fixed by the upper fixing part 1 and the lower fixing part 2. For example, a telescopic spring column can be installed on the ultrasonic transducer 4. Through the telescopic action of the spring column, the ultrasonic transducer 4 is fixed between the upper fixing part 1 and the lower fixing part 2.

[0035] Through the above embodiments, the cavity of the upper fixing part and the accommodating space of the lower fixing part fix and seal the ultrasonic transducer, avoiding the direct exposure of the ultrasonic transducer to the external environment, thereby reducing the influence of high temperature, low temperature, high humidity, and electromagnetic interference of the external environment on the ultrasonic transducer, and reducing the probability of damage or performance degradation of the ultrasonic transducer. At least two ultrasonic transducers are installed inside the ultrasonic transducer fixing device. The upper fixing part and the lower fixing part limit at least two ultrasonic transducers, reducing the axial or circumferential position deviation of the ultrasonic transducers, thereby improving the accuracy of ultrasonic positioning.

[0036] According to the exemplary embodiment, as Figure 1 shown, a partition 12 is provided in the accommodating space of the lower fixing part 2. The partition 12 divides the accommodating space into a first accommodating space 5 and a second accommodating space 6. The first accommodating space 5 matches the shape of the bottom of the ultrasonic transducer 4 so that the bottom of the ultrasonic transducer 4 is accommodated in the first accommodating space 5. The second accommodating space 6 allows the bottom of the ultrasonic transducer 4 to slide in the second accommodating space 6.

[0037] The lower fixing part 2 may also be provided with a ranging part 13 to provide the distance information between the first ultrasonic transducer 4 and the second ultrasonic transducer 4. For example, the ranging part 13 can be a scale provided on the outer side surface or the bottom surface of the lower fixing part 2.

[0038] Through the above embodiments, the ultrasonic transducer is in the first accommodation space, and the bottom of the ultrasonic transducer can slide in the second accommodation space, so that the distance between the ultrasonic transducers in the first and second accommodation spaces can be adjusted. Thus, the measurement requirements for measuring pipelines with different diameters to be measured are met, and the flexibility of the measurement process is improved.

[0039] According to an exemplary embodiment, as Figure 1 shown, the ultrasonic transducer fixing device further includes a through hole 3 and a seal 15. The through hole 3 is provided in the upper fixing part 1, and the specific position of the through hole 3 on the upper fixing part 1 is not limited herein. The seal 15 is sleeved in the through hole 3 for the connecting wire of the ultrasonic transducer 4 to pass through. For example, the seal 15 can be a rubber sleeve.

[0040] Optionally, a connection interface (not shown in the figure) can also be provided on the upper fixing part 1. The connection interface can connect an external device to the ultrasonic transducer. The connection interface can be used to connect a power line or a data line. For example, the connection interface can be an aviation interface.

[0041] Through the above embodiments, the seal seals the through hole, preventing external liquid from entering the ultrasonic transducer fixing device through the through hole, and thus reducing the damage caused by the short circuit of the internal circuit of the ultrasonic transducer.

[0042] Figure 3 shows a schematic installation diagram of the ultrasonic transducer fixing device assembly according to an embodiment of the present application. According to an exemplary embodiment, as Figure 3 shown, an embodiment of the present application further provides an ultrasonic transducer fixing device assembly, including at least two of the above-mentioned ultrasonic transducer fixing devices. The ultrasonic transducer fixing device assembly further includes a fixing member 9.

[0043] Figure 2 shows a schematic structural diagram of the fixing member according to an embodiment of the present application. According to an exemplary embodiment, as Figure 2 shown, connection holes 10 are provided at both ends of the fixing member 9. The connection holes 10 are detachably connected to the ultrasonic transducer fixing device. The fixing member 9 is bent according to a preset curvature so that the ultrasonic transducer fixing device fits the pipeline 11 to be measured.

[0044] For example, the fixing member 9 can be a bent metal sheet with openings at both ends. The fixing member 9 can be made of metals such as iron, aluminum, and copper. The fixing member 9 can also be made of non-metallic materials such as carbon fiber and plastic. The length and curvature of the fixing member 9 can be customized according to user needs to meet the measurement requirements of different objects to be measured. The curvature refers to the bending curvature of the fixing member 9. For another example, the shape of the fixing member 9 can also be customized based on user needs. The fixing member 9 can also be a flexible connecting member such as a spring or a metal wire. After the adjacent ultrasonic transducers are fixed by the fixing member 9, the distance between the adjacent ultrasonic transducers is the same.

[0045] Through the above embodiments, the fixing member can fix at least two ultrasonic transducer fixing devices at equal intervals, enabling accurate axial and circumferential positioning of the ultrasonic transducers in at least two ultrasonic transducer fixing devices, and avoiding the poor axial and axial positioning consistency between paired ultrasonic transducers caused by manual measurement errors when manually installing paired ultrasonic transducers one by one. Furthermore, the consistency between multiple groups of ultrasonic transducers during multi-channel measurement and the accuracy of the measurement results are improved.

[0046] According to another aspect of the present application, an embodiment of the present application further provides a quick-install external ultrasonic flow measurement device, including the ultrasonic transducer fixing device described above.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
