Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic fluid measuring instruments, in particular to an ultra-short radius well fluid measuring instrument bracket. Background Art

[0002] The ultrasonic fluid measuring instrument is an instrument that measures the flow rate of liquid in a circular tube based on the principle of "velocity difference method". Ultrasonic probes are installed at both ends of the side of the ultra-short radius well tube to send and receive signals to each other and measure their respective propagation time. The ultrasonic probe needs to be fixed to the original tube to avoid looseness, but there are still some problems in the installation of existing ultrasonic probes;

[0003] When installing the existing ultrasonic probe, the ultrasonic probe is first adsorbed to the specified position on the side surface of the pipe by a magnet, and then the ultrasonic probe is tied tightly with a steel hoop. During the tightening process, even with the magnet adsorption, the ultrasonic probe is easily displaced, and the position needs to be adjusted back and forth repeatedly. The adjustment of the position causes the ultrasonic probe to rub against the pipe, causing the coupling agent on the surface to fall off, and air to enter between the ultrasonic probe and the pipe, blocking the ultrasonic wave and affecting the measurement data. For this reason, we propose an ultra-short radius wellbore fluid measuring instrument bracket. Utility Model Content

[0024] When installing the existing ultrasonic probe 15, the ultrasonic probe 15 is first adsorbed to the specified position on the side surface of the pipe 4 by a magnet, and then the ultrasonic probe 15 is tied tightly with a steel hoop. During the tightening process, even if there is magnet adsorption, it is easy to cause the ultrasonic probe 15 to move, and the position needs to be adjusted back and forth repeatedly. The adjustment of the position makes the ultrasonic probe 15 rub against the pipe 4, causing the coupling agent on the surface to fall off, and air to enter between the ultrasonic probe 15 and the pipe 4, blocking the ultrasonic wave and affecting the measurement data. By setting the bracket 3, the bracket 3 is attached to the measurement area on the side of the pipe 4, and then the fixing belt 1 and the extension belt 2 are passed around the pipe 4, the bracket 3 is fixed tightly, and then the coupling agent Inject into the inner side of the liquid reservoir of the bracket 3, then insert the first push rod 6 and the second push rod 7, the first rubber stopper 8 and the second rubber stopper 9 are tightly fitted with the liquid reservoir, at this time, put the ultrasonic probe 15 into the inner side of the bracket 3, and make the ultrasonic probe 15 fit with the spring plate 12, and then push the fixing plate 10, the fixing plate 10 pushes the ultrasonic probe 15 to go deeper into the inner side of the bracket 3, the fixing plate 10 pushes the first push rod 6 and the second push rod 7 to move in the liquid reservoir, the first rubber stopper 8 and the second rubber stopper 9 squeeze the coupling agent, and the coupling agent is sprayed out through the coarse nozzle 18 and the fine nozzle 19 respectively. The coarse nozzle 18 has a large radius and the spray direction is the surface of the pipe 4, and the fine nozzle 19 has a small radius and the spray direction is the same as the coarse nozzle 1 8 is in the opposite direction and sprayed onto the surface of the ultrasonic probe 15. When the first push rod 6 moves toward the inside of the liquid reservoir, the spring block 16 will first touch the edge of the liquid reservoir and be pushed into the inside of the slot until the first rubber plug 8 and the second rubber plug 9 completely squeeze out the coupling agent inside the liquid reservoir. At this time, the spring block 16 is aligned with the limiting groove. Under the action of the spring elastic force, the top of the spring block 16 is pushed into the inside of the limiting groove in the slot and contacts with the pressing block 17. At this time, the ultrasonic probe 15 is also in contact with the pipe 4, and there is coupling agent on the contact surface but no air. Since the surface of the pipe 4 is non-planar and has an arc, the pipe 4 will squeeze the ultrasonic probe 15, and the ultrasonic probe 15 will squeeze the spring plate 12. The spring plate 12 Under the force, there is a certain contraction, and the preliminary fixation is completed. Then the screw 13 is rotated. Under the interaction of the threads, the screw 13 rotates and advances inside the thread groove 14, and the push plate 11 at one end of the screw 13 presses against the spring plate 12, so that the spring plate 12 can no longer contract, and the fixation is completed; by setting the bracket 3, the bracket 3 is fixed first, and the coupling agent will not be rubbed off. During the insertion of the ultrasonic probe 15, the coupling agent is sprayed on the surface of the pipe 4 and the ultrasonic probe 15 through the coarse nozzle 18 and the fine nozzle 19, reducing the manual process of applying the coupling agent to the surface of the ultrasonic probe 15, improving work efficiency, spraying evenly, improving measurement accuracy, stable structure, easy disassembly and installation, saving time and effort.
