Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic flowmeters, and specifically to an ultrasonic flowmeter. Background Art

[0002] Measurement is the use of technical and legal means to achieve unit unity and accurate and reliable measurement of quantity values. In metrology science and technology, flow measurement is an important part of it, which is closely related to national production and life, national defense construction and development, and scientific research. Flowmeters are an indispensable part of the national economy and play an important role in aspects such as improving product quality, increasing production efficiency, and the development of metrology science and technology.

[0003] In the actual application of the prior art, the operation process is relatively cumbersome. Specifically, when in use, it is necessary to first evenly apply a coupling agent on the surface of the probe (here, "evenly" is added to ensure the coupling effect and correct the problem of repeated expression "apply apply" in the original text), and then accurately attach the probe to the surface of the pipeline to be measured. After attachment, it is necessary to use a wire tie to fix the probe. This step not only requires additional operation time to adjust the tightness of the tie and ensure firm fixation, but also, due to the limitation of the length specification of the tie, it is difficult to adapt to all diameters or shapes of pipelines.

[0004] This fixing method has two major drawbacks: one is low installation efficiency, and the process of manually adjusting the tie increases the overall installation time cost; the other is insufficient versatility. Different specifications of pipelines require different lengths of ties, resulting in an increase in the complexity of spare parts management and indirectly pushing up the equipment maintenance and procurement costs. Therefore, an ultrasonic flowmeter is needed to solve the above problems. Summary of the Invention

Then push the connecting plate 29, so that the second ratchet block 211 on the outside of the connecting plate 29 pushes the second ratchet wheel 28 to rotate, thereby driving the winding roller 214 to drive the nylon cable tie 223 to wind. At this time, the rotation of the winding roller 214 will drive the chain 220 on the outside of the first sprocket 219 to rotate on the shaft of the second sprocket 221, so that the second sprocket 221 drives the tightening rod 222 and the winding roller 214 to rotate simultaneously. Along with driving the second ratchet wheel 28 to rotate, thereby enabling the winding roller 214 and the tightening rod 222 to tighten the nylon cable tie 223, so as to fix the ultrasonic detection head 1 on the pipeline to be detected;The auxiliary winding component includes the third mounting box 215, which is fixedly connected to the outer end of the ultrasonic detection head 1 away from the first mounting box 21.

Since the first sprockets 219 are arranged in an array, it is beneficial to drive the chain 220 to rotate outside the second sprocket 221; an arc-shaped section for fitting the pipeline is arranged on the outer part of the ultrasonic detection head 1. Since the ultrasonic detection head 1 is provided, it is beneficial to perform detection; two groups of first ratchet blocks 25 and first springs 26 for adjusting the rotation direction of the first ratchet wheel 27 are symmetrically arranged on the outer part of the first ratchet wheel 27. Since the first ratchet blocks 25 are provided, it is beneficial to cooperate with the first springs 26 to limit the first ratchet wheel 27; a second through hole is opened on the first mounting box 21, and the second ratchet wheel 28 is rotatably connected to the inside of the first mounting box 21 through the second through hole. Since the second ratchet wheels 28 are arranged in an array, it is beneficial to cooperate with the second ratchet blocks 211 and the fixing plate 212 to limit the rotation of the winding roller 214; a through groove is opened on the tightening rod 222, and the nylon cable tie 223 can pass through the tightening rod 222 through the through groove.

Since the first push handle 210 is provided, it is beneficial to drive the second sprocket 221 outside the second ratchet wheel 28; when the second ratchet block 211 disengages from the second ratchet wheel 28, at this time, the second ratchet wheel 28 rotates back through the torsion spring 217. Since the torsion spring 217 is provided, it is beneficial to drive the winding roller 214 to wind the nylon cable tie 223.;

[0030] Embodiment 2:

[0031] Please refer to Figure 8 and, in combination with Embodiment 1, it is further obtained that the detection and display component includes an ultrasonic detection display 31, which is fixedly connected to the outside of the winding device 5. An installation plate 32 is fixedly connected to the outside of the ultrasonic detection display 31. A support plate 33 is rotatably connected to the outside of the installation plate 32. One end of the support plate 33 away from the installation plate 32 is rotatably connected to a flip plate 36. One end of the installation plate 32 away from the support plate 33 is rotatably connected to a bottom plate 34. A plug plate 35 is slidably connected to the inside of the bottom plate 34. Since the ultrasonic detection display 31 is provided, it is beneficial to display the data measured by the ultrasonic detection head 1.

[0032] In the actual operation process, when this device is used, first rotate the placement plate 32, support plate 33, bottom plate 34, insertion plate 35, and flipping plate 36 in sequence to fix the ultrasonic detection display 31. Subsequently, apply the coupling agent to the outside of the ultrasonic detection head 1. Then, pull the nylon tie 223 to wind around the pipeline, and insert the nylon tie 223 into the inside of the tightening rod 222. By pushing the push handle 210, drive the connecting plate 29 to rotate outside the ratchet wheel 28. The ratchet block 211 on the outside of the connecting plate 29 cooperates with the spring 213 to move outside the ratchet wheel 28. Subsequently, push the connecting plate 29, so that the ratchet block 211 on the outside of the connecting plate 29 pushes the ratchet wheel 28 to rotate, thereby driving the winding roller 214 to wind up the nylon tie 223. At this time, the rotation of the winding roller 214 will drive the chain 220 on the outside of the sprocket 219 to rotate on the shaft of the sprocket 221, so that the sprocket 221 drives the tightening rod 222 and the winding roller 214 to rotate simultaneously. Along with driving the ratchet wheel 28 to rotate, thereby the winding roller 214 and the tightening rod 222 tighten the nylon tie 223, thus fixing the ultrasonic detection head 1 on the pipeline to be detected.

[0033] Through the above steps, insert the nylon tie 223 into the tightening rod 222, and push the push handle 210 to drive the connecting plate 29 to rotate outside the ratchet wheel 28. The ratchet block 211 on the connecting plate 29 moves along the surface of the ratchet wheel 28 under the action of the spring 213. Continue to push the connecting plate 29, and the ratchet block 211 pushes the ratchet wheel 28 to rotate, driving the winding roller 214 to wind up the nylon tie 223. When the winding roller 214 rotates, it drives the sprocket 221 to rotate through the sprocket 219 and the chain 220, and further makes the tightening rod 222 and the winding roller 214 rotate synchronously. Continuously push the ratchet wheel 28, and the winding roller 214 and the tightening rod 222 jointly tighten the nylon tie 223, which is convenient for quickly fixing the ultrasonic detection head 1 on the pipeline to be measured, improving the installation efficiency, saving time, and adapting to different pipe diameters, expanding the applicable range of the device.
