Description

Technical Field

[0001] The utility model relates to the technical field of water flow measurement, in particular to an ultrasonic measuring device. Background Art

[0002] Ultrasonic flow meters work based on the ultrasonic time difference principle. When the ultrasonic sound beam propagates downstream and upstream in the water, a time difference will occur due to changes in speed. By analyzing and processing this time difference, the water flow rate can be obtained and the water flow rate can be further calculated.

[0003] Traditionally, the bracket used to install the ultrasonic signal reflector located in the pipeline is prone to shaking due to fluid pressure or external forces, which not only affects measurement accuracy but also reduces service life. Therefore, we proposed an ultrasonic metering device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the bracket for mounting the ultrasonic signal reflecting plate is easily shaken due to fluid pressure or external force, which not only affects the measurement accuracy but also reduces the service life, and to propose an ultrasonic measuring device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The device also includes:

[0007] Two sets of reflection components are respectively arranged at the two ends of the reflection bracket, and are used to reflect the ultrasonic waves emitted by the ultrasonic probe to realize flow calculation;

[0008] The fixing component is arranged on the outer wall of the pipe body and is used to stably fix the ultrasonic water meter on the pipe body to prevent shaking.

[0009] In one possible design, the reflective assembly includes a positioning plate, and the inner wall of one end of the reflective bracket is symmetrically provided with sliding grooves, and the two sides of the positioning plate are respectively inserted into the corresponding sliding grooves. The inner walls on both sides of the positioning plate are fixedly connected with the same reflective plate, and the reflective plate is set at a certain angle. The setting of the positioning plate facilitates the installation and replacement of the reflective plate.

[0010] In one possible design, two clamping blocks are symmetrically fixed on the top of the positioning plate, and a clamping slot corresponding to the clamping block is opened on the top inner wall of the slide groove. The clamping block and the corresponding clamping slot are clamped together, and the positioning plate inserted into the slide groove is fixed by the provided clamping blocks and the clamping slot to prevent it from falling off.

[0011] In a possible design, two rubber rings for sealing are symmetrically provided on the outer wall of the reflective bracket.

[0012] In one possible design, two positioning components are symmetrically arranged inside the tube body, and the positioning components are composed of two positioning blocks. A groove is provided on the side where the two positioning blocks are close to each other. One end of the reflector bracket is inserted into the corresponding groove and clamped with the groove.

Two through holes are symmetrically opened on the two mounting ears. Mounting screws are arranged in the four through holes, and the four mounting screws are all connected to the bottom thread of the ultrasonic water meter.

[0014] In the present application, when the device is working, the ultrasonic transmitting probe in the ultrasonic probe transmits an ultrasonic signal into the fluid. After passing through the reflective plates designed at specific angles in the two sets of reflective components, the ultrasonic signal can be effectively reflected back to the ultrasonic receiving probe and received. Among them, the positioning grooves and bolts on the reflective bracket cooperate, and one end of the reflective bracket is clamped with the two positioning blocks in the tube body, ensuring the stability of the reflective component and avoiding the reflection effect affected by the shaking of the fluid pressure. Then, the ultrasonic water meter electrically connected to the two ultrasonic receiving probes calculates the flow rate and flow rate through the transmission time difference of the ultrasonic signal;

[0015] In addition, the reflective component is clamped with the slot in the reflective bracket slide through the clamping block on it, so that the reflective plate used for reflection can be removed for easy replacement and maintenance. At the same time, the rubber ring on the outer wall of the reflective bracket further ensures the stability and sealing of the reflective bracket in the pipe body.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Reference Figure 1-5 A metering device includes a tube body 1, with flanges 2 fixedly provided at both ends of the tube body 1 to facilitate connection of the device to the pipeline system. A positioning hole 5 is provided on the outer wall of the tube body 1. The interior of the positioning hole 5 is threaded and is threaded with bolts for further securing other components within the device. Mounting holes 4 are symmetrically provided on the outer wall of the tube body 1 on both sides of the positioning hole 5. An ultrasonic transmitting probe and an ultrasonic receiving probe are respectively fixed to the inner walls of the two mounting holes 4. These two probes together constitute an ultrasonic probe 6. The ultrasonic transmitting probe is used to emit ultrasonic signals, while the ultrasonic receiving probe is responsible for receiving ultrasonic signals after being reflected by the fluid.

[0029] An ultrasonic water meter 9 is also installed on the outer wall of the pipe body 1. This ultrasonic water meter 9 is electrically connected to the two ultrasonic probes 6 and is used to receive and process the signals collected by the ultrasonic probes 6 to calculate the fluid flow rate. To optimize the reflection effect of the ultrasonic signal, a reflective bracket 7 is installed inside the pipe body 1. The reflective bracket 7 has a positioning slot 10. Bolts can pass through the pipe body 1 and extend into the positioning slot 10 to ensure the stable installation of the reflective bracket 7.

[0030] In addition, this embodiment includes two sets of reflective components, which are respectively arranged at both ends of the reflective bracket 7. These sets of reflective components are used to reflect the ultrasonic signal emitted by the ultrasonic probe 6, ensuring that the signal can be accurately received, thereby achieving accurate flow calculation. In order to fix the ultrasonic water meter 9 and prevent it from shaking during operation, this embodiment also provides a fixing assembly. This fixing assembly includes two mounting ears 3 symmetrically arranged on the outer wall of the tube body 1. Each mounting ear 3 has a through hole and is threadedly connected to the bottom of the ultrasonic water meter 9 via mounting screws.

[0031] Specifically, the reflector assembly includes a positioning plate 12. A symmetrical groove is defined on the inner wall of one end of the reflector bracket 7. The two sides of the positioning plate 12 are inserted into corresponding grooves. A reflector plate 13 is fixedly attached to the inner walls of both sides of the positioning plate 12. The reflector plates 13 are positioned at a certain angle to facilitate the reflection of ultrasonic signals. To facilitate the installation and replacement of the reflector plates 13, two symmetrical retaining blocks 14 are fixedly positioned on the top of the positioning plate 12. The inner wall of the top of the groove has corresponding slots for the retaining blocks 14. The retaining blocks 14 engage with the corresponding slots, ensuring the stable fixation of the positioning plate 12 within the groove.

[0032] The present application can be used in the field of water flow measurement technology, and can also be used in other fields applicable to the present application.

[0033] Example 2: Reference Figure 3-5 , improved on the basis of Example 1: an ultrasonic metering device, which is applied to the field of water flow metering technology, two rubber rings 11 are symmetrically provided on the outer wall of the reflecting bracket 7, and the two rubber rings 11 not only play the role of sealing to prevent fluid leakage, but also play the role of supporting the reflecting bracket 7, thereby enhancing its stability.

[0034] Two symmetrical positioning members are located within the tube body 1. Each of these positioning members consists of two positioning blocks 8. A groove is defined on the adjacent sides of the two positioning blocks 8. One end of the reflector bracket 7 can be inserted into the corresponding groove and locked into place. This ensures that the reflector bracket 7 is securely fixed within the tube body 1.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of ultrasonic probe devices and ultrasonic water meter devices are commonplace, and are conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
