[0002] Ultrasonic flow meter is an instrument that uses ultrasonic technology to measure fluid velocity and flow rate. It calculates the fluid velocity and flow rate by sending ultrasonic signals into the fluid, then receiving echo signals and analyzing their frequency and time delay.

[0003] The probe of the ultrasonic flow meter is fixed on the outside of the pipeline, and the feedback data is statistically analyzed using ultrasonic technology to measure the flow rate in the pipeline. The current ultrasonic flow meter probe does not have a positioning mechanism outside the probe to complete the fixation of the probe. The commonly used fixing method is to fix the probe with a chain tensioner.

[0004] In the current prior art, the fixing method using a tensioner is relatively cumbersome and needs to be carried at all times to facilitate fixing of the ultrasonic flow meter probe. Therefore, an ultrasonic flow meter probe positioning mechanism is proposed to solve the above-mentioned problem. Utility Model Content

[0012] Furthermore, a cavity is provided inside the probe body, the lower end of the second baffle extends into the cavity, and a movable plate is fixedly installed at the lower end of the second baffle, the movable plate is slidably connected to the cavity, and a reset spring is installed between the movable plate and the inner wall of the cavity.

[0013] Furthermore, a damping block located on the side wall of the slide groove is fixedly mounted on the first bottom frame, through the relative fit between the damping block and the limiting strip.

[0014] Furthermore, a recessed groove is provided on the second bottom frame, a hinge shaft is rotatably mounted on one end of the recessed groove facing the end of the slide groove, and the connecting plate is rotatably connected to the hinge shaft.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-3 In this embodiment, an ultrasonic flow meter probe positioning mechanism includes a probe body 1 and an extension frame located on the probe body 1, wherein a connector 2 is installed on one side of the probe body 1 for connecting to a flow meter terminal device, and the extension frame includes two groups symmetrically arranged on the front and rear sides of the probe body 1.

[0023] In the present application, the probe body 1 is attached to the outside of the pipe wall, and the extension frames on both sides of the probe body 1 are connected to each other after crossing the pipe to achieve the clamp positioning of the probe body 1.

[0024] In this embodiment, the extension frame includes a first bottom frame 3 , a second bottom frame 9 slidably connected to the first bottom frame 3 , and a connecting plate 14 rotatably connected to the second bottom frame 9 .

[0025] Preferably, a sliding groove 7 is provided on the surface of the first bottom frame 3 , and the second bottom frame 9 is slidably connected to the sliding groove 7 .

[0026] In a specific implementation, the second bottom frame 9 can be extended to the outside of the first bottom frame 3 to complete the connection by sliding the second bottom frame 9 relative to the first bottom frame 3 .

[0027] It should be noted that a connecting bolt 4 is fixedly mounted on the first bottom frame 3 , and one end of the connecting bolt 4 penetrates into the outer shell of the probe body 1 and slides relative to the probe body 1 .

[0028] This design enables the first bottom frame 3 to rotate relative to the probe body 1 and to slide relative to the probe body 1 to adjust the spacing, so that pipes in different diameter ranges can be adapted and adjusted.

[0029] A first baffle 5 is fixedly mounted on the outer shell wall of the probe body 1 in this embodiment, and a second baffle 6 is provided to limit the position of the first bottom frame 3. At the same time, a damping sleeve is installed at the connection between the connecting bolt 4 and the probe body 1 to reduce the phenomenon of random movement of the first bottom frame 3.

[0030] In this embodiment, a limit strip 10 is fixedly installed on one end of the second bottom frame 9 , a limit block 8 located at the end of the slide groove 7 is fixedly installed inside the first bottom frame 3 , and the limit strip 10 abuts against the limit block 8 .

[0031] It is worth noting that a damping block 11 located on the side wall of the slide groove 7 is fixedly installed on the first bottom frame 3. Through the relative fit between the damping block 11 and the limit strip 10, the sliding of the limit strip 10 can be hindered to a certain extent, making it convenient to store the limit strip 10.

[0032] In a specific implementation, the second bottom frame 9 can be restricted from being separated from the first bottom frame 3 by the abutment of the limiting strip 10 against the limiting block 8 .

[0033] It should be noted that a groove may be further provided on the inner wall of the slide groove 7 to cooperate with the limit block 8 to further limit the sliding of the second bottom frame 9 to prevent the second bottom frame 9 from falling out of the slide groove 7 .

[0034] In this embodiment, a recessed groove 12 is provided on the second bottom frame 9, and a hinge shaft 13 is rotatably installed on one end of the recessed groove 12 facing the end of the slide groove 7. The connecting plate 14 is rotatably connected to the hinge shaft 13. Through the connection of the hinge shaft 13, the connecting plate 14 can be rotated and deflected relative to the second bottom frame 9, thereby realizing the fitting and fixation of the two connecting plates 14.

[0035] In this embodiment, two connecting plates 14 are respectively fixed with positioning buckles 15 and provided with positioning holes 16. The positioning buckles 15 correspond to the positioning holes 16. The positioning buckles 15 can adopt a button structure, and a sealing ring is added on the outside to improve the stability of the connection.

[0036] It should be noted that there are a plurality of positioning holes 16 continuously distributed on the connecting plate 14 so that the connecting plate 14 can adapt to connections with different spacings.

[0037] The probe body 1 in this embodiment also has a cavity 18 inside, the lower end of the second baffle 6 extends into the cavity 18, and a movable plate 17 is fixedly installed on the lower end of the second baffle 6, the movable plate 17 is slidably connected to the cavity 18, and a reset spring 19 is installed between the movable plate 17 and the inner wall of the cavity 18.

[0038] In a specific implementation, the movable plate 17 can be pushed by the return spring 19 so that the second baffle 6 can extend to the outside of the probe body 1 .

[0039] The working principle of the above embodiment is:

[0040] When it is necessary to measure the pipeline flow, a coupling agent is applied to the outside of the probe body 1 in advance, and then the probe body 1 is placed on the side or top of the pipeline, and the first bottom frame 3 on the outside of the probe body 1 is pulled and extended relative to the probe body 1, and then the first bottom frame 3 is rotated toward the radial direction of the pipeline, and the second bottom frame 9 is slid relative to the first bottom frame 3 in turn, and the connecting plate 14 is rotated so that the connecting plate 14 is bent ninety degrees into an L shape relative to the first bottom frame 3. At this time, the L-shaped connecting plates 14 on both sides of the probe body 1 are buckled in corresponding positions with each other, and the positioning buckles 15 are buckled in the positioning holes 16 to complete the positioning of the probe body 1 relative to the pipeline.
