Description

Technical Field

[0001] This utility model relates to the field of external clamp-on ultrasonic instruments and meters, and in particular to a mounting bracket for an external clamp-on ultrasonic transducer. Background Technology

[0002] With increasing environmental awareness in recent years, natural gas, as a clean and high-quality energy source, is being used more and more, leading to rapid development in the natural gas industry. The main metering instruments used in the natural gas industry are Roots meters and turbine meters; however, these traditional instruments have drawbacks such as high requirements for metering quality, frequent maintenance, high maintenance costs, and low levels of intelligence. These shortcomings hinder the rapid development of the natural gas industry.

[0003] Compared with differential pressure instruments, volumetric instruments, and traditional velocity instruments, ultrasonic gas flow meters offer advantages such as a wide range, intelligent operation, easy installation, low cost, high precision, long service life, and low maintenance costs. Currently, they are widely used in the following fields: 1) metering management of high-pressure long-distance natural gas pipelines and provincial / municipal distribution stations; 2) urban gas metering management; 3) natural gas and coalbed methane extraction and utilization; 4) liquefied natural gas and liquefied petroleum gas; 5) metering management of gas consumption in large-scale industrial applications; 6) blast furnace gas and coke oven gas metering; and 7) other energy-saving and emission-reduction gas emission metering.

[0004] Ultrasonic gas flow meters are available in various installation types, including short-section (with pipe section), insertion, and clamp-on. In industrial applications, some special working conditions require safety considerations to prevent damage to the flow pipeline, making clamp-on ultrasonic gas flow meters widely used in these scenarios. However, common clamp-on ultrasonic gas flow meter brackets in existing technology lack directional adjustment capabilities, and many brackets are slightly misaligned. In the installation and application environment, if the transducer is installed at an inaccurate angle, it can lead to reduced signal transmission and reception, weaker signals, or even no signal at all, thus affecting the flow meter's normal measurement. Furthermore, traditional installation methods rely on cable ties or chains for fixation; insufficient tightening can cause the transducer to detach, while excessive tightening can deform the transducer crystal, leading to static parameter drift and measurement errors.

[0010] A transducer clamp is used to fix and clamp the transducer. The transducer clamp is fitted on the transverse connecting rod to enable it to slide. The transducer is snapped into the inner side of the transducer clamp, and one side of the transducer abuts against the pipe being tested.

[0011] Preferably, the top of the transducer clamp is provided with a first locking screw for adjusting the fastening force of the transducer, the two sides of the transducer clamp are provided with second locking screws for adjusting the longitudinal position of the transducer, and the connection between the transducer clamp and the transverse connecting rod is provided with a third locking screw.

[0025] Example

[0026] Please see Figures 1-3This utility model provides a mounting bracket for an externally clamped ultrasonic transducer. The mounting bracket comprises an arc-shaped fixing seat 3, a longitudinal connecting rod 4, a transverse connecting rod 2, and a transducer clamp 1. The arc-shaped fixing seat 3 is used to fix the entire device onto the pipe 7 under test. In this embodiment, four arc-shaped fixing seats 3 are used. The inner wall of the arc-shaped fixing seat 3 is set to an arc shape and matches the diameter of the pipe 7 under test. During installation, two arc-shaped fixing seats 3 are fixed to the pipe 7 under test facing each other. The arc-shaped fixing seat 3 is provided with mounting holes 12. The two ends of the longitudinal connecting rod 4 are threaded, and the two ends of the longitudinal connecting rod 4 are respectively passed through the mounting holes 12. Hole 12 is fixedly connected to the bow-shaped fixing seat 3 via nut 5; and a connecting hole 11 for support is provided on the side of the bow-shaped fixing seat 3. The two ends of the transverse connecting rod 2 are fixed to the connecting hole 11 of the bow-shaped fixing seat 3 in the horizontal direction respectively; wherein the transducer clamp 1 is used to fix and clamp the transducer 6. The transducer clamp 1 is fitted onto the transverse connecting rod 2 to enable it to slide. The transducer 6 is snapped into the inner side of the transducer clamp 1. One side of the transducer 6 abuts against the pipe 7 to be measured. The top of the transducer clamp 1 is provided with a locking screw 8 for adjusting the fastening force of the transducer 6. The locking screw 8 is a hexagonal Torx screw for easy manual tightening. The transducer clamp 1 has locking screws 9 on both sides for adjusting the longitudinal position of the transducer 6. The transducer clamp 1 is connected to the transverse connecting rod 2 by locking screws 10. The transverse connecting rod 2 is cylindrical and has dimensional scales engraved on its surface. The relative position of the transducer clamp 1 and the transverse connecting rod 2 is fixed by locking screws 10. The clamping force and installation angle of the transducer 6 can be adjusted by adjusting locking screws 8 and 9 on the transducer clamp 1. The transducer clamp 1 can effectively ensure the installation angle and fixed position of the transducer 6, realize accurate flow metering and long-term stable use, and avoid the maintenance problems caused by inaccurate installation angle and loose fixing of the transducer 6.

[0027] During installation, first, the transducer clamp 1 is fitted onto the transverse connecting rod 2, and the assembly of the transducer clamp 1 and the transverse connecting rod 2 is installed on the bow-shaped fixing seat 3. The two ends of the transverse connecting rod 2 are fixed horizontally to the connecting holes 11 on the side of the bow-shaped fixing seat 3. Then, the two ends of the longitudinal connecting rod 4 are passed through the mounting holes 12 and fixed to the bow-shaped fixing seat 3 with nuts 5, so that the two bow-shaped fixing seats 3 are fixed facing each other on the pipe 7 to be tested. Loosen the locking screws on the transducer clamp 1 and snap the transducer 6 into the inside of the transducer clamp 1. Finally, the installation position of the transducer 6 is calculated based on the pipe diameter and installation angle of the pipe 7 being measured. The relative position of the transducer clamp 1 and the horizontal direction on the transverse connecting rod 2 is adjusted by the scale on the transverse connecting rod 2, and the locking screw 10 is tightened. The vertical position of the transducer 6 in the transducer clamp 1 is adjusted by the locking screw 9 to adjust its installation angle. After the position of the transducer 6 is fixed, the tightening force of the external clamp transducer 6 is adjusted by the locking screw 8 to ensure that the transducer 6 is in a suitable operating pressure range, thus ensuring measurement accuracy and the lifespan of the transducer 6.

[0028] Therefore, the external clamp-type ultrasonic transducer mounting bracket used in this utility model can ensure the transducer installation angle, achieve accurate flow meter measurement, and ensure long-term stable use. It effectively reduces the maintenance problems caused by inaccurate transducer installation angle and insufficient or excessive tightening force. At the same time, the mounting bracket is installed on the outside of the pipe being measured and is not affected by internal gas or liquid. The overall transducer clamp can be used for gas and liquid pipeline flow measurement. Furthermore, the transducer clamp is fixed by locking screws and can be adapted to transducers of various specifications and sizes.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
