Description

Technical Field

[0001] The invention relates to a small-diameter ultrasonic flow measurement auxiliary device, belonging to the field of external clamp-on ultrasonic flow meter measurement. Background Art

[0002] The clamp-on ultrasonic flowmeter is a non-invasive flow measurement device that measures the flow of the medium inside the pipeline by installing a transducer on the outside of the pipeline and using the propagation time difference principle of ultrasonic waves. This flowmeter has the advantages of no contact with the medium, easy installation and maintenance, and wide adaptability. Therefore, it has been widely used in the petroleum, chemical, water supply and drainage industries. However, the existing clamp-on ultrasonic flowmeter is mainly used for flow measurement of large-diameter pipelines, but there are certain technical challenges in the application of small-diameter pipelines.

[0003] For small-diameter pipes, the propagation path of ultrasonic signals is short, and the installation accuracy of the transducer has a significant impact on the measurement results. At the same time, flexible pipes are prone to deformation when subjected to external forces, resulting in changes in the pipe diameter, which further increases the complexity of ultrasonic signal propagation within the pipe wall, thereby affecting the accuracy of flow measurement. In addition, most existing external clamp-type ultrasonic flowmeters have a complex structure and are difficult to adapt to the precise clamping and installation requirements of small-diameter pipes. Especially in pipes made of some flexible materials, existing clamps often cannot fit tightly to the pipes, resulting in reduced measurement accuracy or even inability to perform effective measurements. Summary of the invention

[0004] The invention relates to a small-diameter ultrasonic flow measurement auxiliary device.

[0005] The specific technical solutions adopted by the present invention are as follows:

[0006] A small-diameter ultrasonic flow measurement auxiliary device includes a transducer clamp, a semicircular tube, a hinge mechanism, a connecting buckle, a restraining rope, a torque controller, and a connecting hook. The device is characterized in that the semicircular tube adopts a convenient structure, can be quickly opened and closed, and is suitable for the installation and disassembly of various small-diameter test pipelines.

[0007] The transducer fixture is connected to the semicircular tube through a hinge mechanism and a connecting buckle, and the clamping position can be accurately adjusted to adapt to small-diameter test pipes of different sizes.

[0008] Tie ropes and connecting hooks are used to further secure the pipeline, and are particularly suitable for restraining flexible pipelines to prevent pipeline deformation and measurement errors.

[0009] The torque controller is used to precisely fine-tune the tension of the tie rope on the semicircular pipe to ensure a tight fit between the test pipe and the ultrasonic flow measurement auxiliary device.

[0010] The advantages and positive effects of the present invention are as follows:

[0011] (1) The present invention realizes the rapid installation and disassembly of the test pipe through the semicircular pipe design, and is suitable for small-diameter pipes of different sizes. The binding rope, connecting hook and torque controller ensure the close fit between the pipe and the measurement auxiliary device, especially the flexible pipe, to avoid the measurement error caused by the deformation of the pipe, thereby improving the accuracy of the flow measurement. This design not only improves the installation efficiency, but also makes the device adaptable to various pipe types and has good versatility.

[0012] (2) The present invention adopts a hinge mechanism and a connecting buckle structure design, which can accurately adjust the relative position of the fixture and the pipeline, ensuring the accurate installation of the transducer and the stability of the signal transmission path. This structural design effectively solves the problem of loose fitting caused by slight diameter differences in small-diameter pipelines, ensures the accuracy and repeatability of the measurement, and greatly simplifies the operation process and improves work efficiency.

[0023] The present invention is further described below with reference to the accompanying drawings using an embodiment, but this embodiment is merely illustrative and the protection scope of the present invention is not limited by this embodiment.

[0024] Combination Figures 1 to 8 A small-diameter ultrasonic flow measurement auxiliary device is described in detail: A small-diameter ultrasonic flow measurement auxiliary device includes a transducer clamp 1, a semicircular tube 2, a hinge mechanism 3, a connecting buckle 4, a binding rope 5, a torque controller 6, and a connecting hook 7. The semicircular tube 2 and the transducer clamp 1 are connected to each other through the hinge mechanism 3 and the connecting buckle 4. For the installed test pipe, the semicircular tube 2 can be quickly opened and closed through the hinge mechanism 3 and the connecting buckle 4, which is suitable for quickly installing and disassembling the test pipe. The connecting hook 7 is located at the end of the binding rope 5, which is used to hook it on the semicircular tube 2. The torque controller 6 controls the clamping force of the binding rope 5 on the small-diameter ultrasonic flow measurement auxiliary device to ensure that the test pipe and the ultrasonic flow measurement auxiliary device fit tightly.

[0025] The advantages and positive effects of the present invention are as follows:

[0026] (1) The present invention can apply precise clamping force to the test pipe through the coordinated design of the binding rope, torque controller, and torque controller, so that the pipe fits tightly with the transducer fixture after being fixed. Especially for flexible pipes, the binding rope effectively prevents the pipe from affecting the measurement due to deformation, thereby maintaining the geometric shape of the pipe and ensuring that the ultrasonic signal can be stably transmitted and accurately measured.

[0027] (2) The semicircular tube design of the present invention evenly distributes the clamping force to prevent uneven deformation of the pipe diameter, and is particularly suitable for flexible pipes with small diameters. When the pipes are tightly fitted, the stability of the ultrasonic signal propagation path can be guaranteed, thereby improving the accuracy and repeatability of flow measurement.

At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
