Description

Technical Field

[0001] This application relates to the technical field of flow velocity detection, and more specifically, to a portable vertical multilayer ultrasonic flow measurement device. Background Technology

[0002] In the field of flow velocity detection technology, the ultrasonic time-of-flight method is a commonly used method for measuring liquid flow velocity. The ultrasonic time-of-flight method includes two approaches: the through-beam method and the reflection method. Existing portable vertical multilayer ultrasonic flow measurement devices, in order to obtain a relatively stable flow field and a relatively uniform flow velocity, place the ultrasonic transducer on a long, straight channel with a length and cross-section that meet the requirements and whose cross-sectional area remains constant. For open channels such as rivers and open channels, a portable vertical multilayer ultrasonic flow measurement device with pipes open on both sides can be used, inserted perpendicular to the direction of water flow into the open channel, to measure flow velocity using either the through-beam or reflection method.

[0003] The inventors of this application discovered that when measuring the flow velocity in an open channel, the single-channel ultrasonic velocity measuring device can only measure the velocity at one depth within the cross-section of the open channel at a time. However, in reality, the flow velocity varies significantly at different depths in an open channel. Using the velocity at a single depth to represent the velocity of the entire open channel leads to problems such as inaccurate measurement, a large measurement blind zone, and poor linearity of the measurement results. Furthermore, ultrasonic transducers exposed to water are prone to rusting and damage. Moreover, if multiple sets of ultrasonic transducers are manually arranged, inconsistencies in arrangement and inaccurate positioning can cause measurement errors.

[0014] Beneficial effects

[0015] The portable vertical multi-layer ultrasonic flow measurement device of this application is designed with different auxiliary measuring components stacked and fixed, with two ultrasonic transducers set on each auxiliary measuring component along the flow direction of the fluid to be measured. The different auxiliary measuring components have different heights, thus enabling the measurement of flow velocities at different depths.

Furthermore, multiple sets of auxiliary measuring components are pre-fixed together, eliminating the need for rearrangement for each measurement, thus solving the problem of inconsistent and inaccurate positioning that can occur when manually arranging components separately, leading to measurement errors.

[0027] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order.

[0028] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Figure 1 A schematic diagram illustrating the principle of ultrasonic reflection is shown. Figure 1 As shown, the acoustic channel angle β is the angle between the propagation paths of ultrasonic transducers A and B and the velocity direction of the fluid along the channel axis. V in the figure represents the fluid velocity. The axial spacing L of the ultrasonic transducers is the distance between ultrasonic transducers A and B along the channel axis in a group of ultrasonic transducers.

[0030] In current open channel flow velocity measurement, portable vertical multi-layer ultrasonic flow measurement devices using a single channel can only measure the flow velocity at one depth within the channel's cross-section at a time. The flow velocity varies significantly at different depths in an open channel, making it inaccurate to represent the overall flow velocity of the entire channel using the velocity at a single depth. Furthermore, ultrasonic transducers exposed to water are prone to rusting and damage. Moreover, manually arranging multiple sets of ultrasonic transducers each time can lead to inconsistent placement, inaccurate positioning, and measurement errors.

[0031] Figure 2 A schematic diagram of the structure of a portable vertical multilayer ultrasonic flow measurement device according to an embodiment of this application is shown. Figure 3 A schematic diagram of the structure of an ultrasonic transducer installed on an auxiliary measuring component according to an embodiment of this application is shown.

[0032] According to the example embodiment, such as Figure 2 and Figure 3 As shown, the portable vertical multilayer ultrasonic flow measurement device 1 includes a measurement host 11, at least two sets of ultrasonic transducer groups 12, at least two auxiliary measuring components 13, a signal transmission component 14, a first protective component 15, a second protective component 16, and a fixing component 17. Each of the at least two sets of ultrasonic transducer groups 12 includes a first ultrasonic transducer 121 and a second ultrasonic transducer 122. Each of the at least two auxiliary measuring components 13 is a rectangular cross-section tubular structure with openings on both sides to allow the fluid to be measured to pass through, and all auxiliary measuring components 13 are arranged parallel to each other.

[0033] For example, the fluid to be tested is a liquid. For instance, the liquid could be water, and the fluid to be tested could be water in an open channel. For example, if the auxiliary measuring element 13 is a rectangular cross-section tubular structure, the fit between adjacent auxiliary measuring elements 13 will be improved, thereby improving the tightness of all auxiliary measuring elements 13 when assembled together.

[0034] The first ultrasonic transducer 121 and the second ultrasonic transducer 122 of each auxiliary measuring element 13 are arranged on the same outer wall of the corresponding auxiliary measuring element 13 along the flow direction of the fluid to be measured. One end of the signal transmission element 14 is connected to at least two sets of ultrasonic transducer groups 12, and the other end is connected to the measuring host 11. The signal transmission element 14 includes a first signal transmission element 141 and a second signal transmission element 142. One end of the first signal transmission element 141 is connected to all the first ultrasonic transducers 121, and the other end is connected to the measuring host 11. One end of the second signal transmission element 142 is connected to all the second ultrasonic transducers 122, and the other end is connected to the measuring host 11.

[0035] For example, both the first signal transmission element 141 and the second signal transmission element 142 can be signal lines. Exemplarily, the signal lines can be shielded wires. For example, the measuring host 11 can be a measuring device with computing capabilities. Exemplarily, the measuring host 11 can calculate the flow rate of the liquid to be measured based on ultrasonic information and ultrasonic transmission time.

[0036] A first protective member 15 is disposed on all auxiliary measuring members 13, and a first accommodating space is formed inside the first protective member 15 to accommodate all the first ultrasonic transducers 121 and the first signal transmission member 141. A second protective member 16 is disposed on all auxiliary measuring members 13, and a second accommodating space is formed inside the second protective member 16 to accommodate all the second ultrasonic transducers 122 and the second signal transmission member 142. A fixing member 17 is connected to the outer wall of each auxiliary measuring member 13 that is provided with ultrasonic transducers to fix at least two auxiliary measuring members 13.

[0037] Alternatively, the auxiliary measuring element 13 can also be a circular tubular structure with openings on both sides.

[0038] For example, the length of the fastener can be greater than the total length of all the auxiliary measuring parts when they are fixed together. This ensures that at least one end of the fastener is outside the outer edge of the assembly of all the auxiliary fasteners. This design allows the user to operate by holding the part of the fastener that extends outside the outer edge of the assembly of all the auxiliary fasteners, which is more convenient for the user and improves the ease of use and portability.

[0039] For example, the size of the ultrasonic transducer and the size of the measuring tube can be determined by the user according to the measurement requirements; there are no restrictions on these.

[0040] For example, the ultrasonic waves emitted by the first ultrasonic transducer 121 are reflected and received by the second ultrasonic transducer 122, and the ultrasonic waves emitted by the second ultrasonic transducer 122 are reflected and received by the first ultrasonic transducer 121. Exemplarily, the inner wall of the auxiliary measuring member 13 can reflect ultrasonic waves. For example, both the first protective member 15 and the second protective member 16 can be metal structures containing accommodating spaces.

[0041] Through the above embodiments, the portable vertical multi-layer ultrasonic flow measurement device of this application is designed with different auxiliary measuring components stacked and fixed, and two ultrasonic transducers are set on each auxiliary measuring component along the flow direction of the fluid to be measured. The different auxiliary measuring components have different heights, thus enabling the measurement of flow velocities at different depths, thereby solving the problem of large measurement blind zones in single-depth measurements. By measuring flow velocities at different depths, the accuracy and linearity of flow velocity measurement in open channels are improved. The portable vertical multi-layer ultrasonic flow measurement device of this application has a protective component designed above the ultrasonic transducers for sealing and protecting the transducers, thereby reducing the probability of the ultrasonic transducers rusting or being damaged when exposed to water. In addition, multiple sets of auxiliary measuring components are pre-fixed together, eliminating the need for rearrangement for each measurement, thus solving the problem of poor consistency and inaccurate positioning that can lead to measurement errors when manually arranged separately.

[0042] Optionally, the portable vertical multilayer ultrasonic flow measurement device 1 further includes a first sealing sleeve and a second sealing sleeve. The first sealing sleeve is fitted onto the first signal transmission element 141. The second sealing sleeve is fitted onto the second signal transmission element 142.

[0043] For example, both the first and second sealing sleeves can be heat shrink tubing or rubber spiral tubing.

[0044] Through the above embodiments, the technical solution of this application provides protection for the signal transmission component by covering the outer surface of the signal transmission component with a sealing sleeve that has a sealing and protective function, thereby reducing the possibility of damage to the signal transmission component and improving the stability of the portable vertical multilayer ultrasonic flow measurement device.

[0045] Optionally, the first protective member 15 is a first U-shaped groove structure with an opening on one side, and the opening side of the first U-shaped groove structure is sealed to the outer wall of each auxiliary measuring member 13 where an ultrasonic transducer is provided. The second protective member 16 is a second U-shaped groove structure with an opening on one side, and the opening side of the second U-shaped groove structure is sealed to the outer wall of each auxiliary measuring member 13 where an ultrasonic transducer is provided.

[0046] For example, the sealing connection described above can be achieved by glue sealing or welding sealing.

[0047] Through the above embodiments, the technical solution of this application, by designing the protective component as a U-shaped groove structure, achieves better fit between the internal accommodating space of the protective component and the ultrasonic transducer. Furthermore, the U-shaped groove structure facilitates a more convenient and better-sealed connection with the auxiliary measuring component, thereby reducing the probability of the ultrasonic transducer coming into contact with water, and thus reducing the possibility of damage to the portable vertical multilayer ultrasonic flow measurement device.

[0048] Figure 4 A schematic diagram of the structure of a measurement host according to an embodiment of this application is shown. According to an example embodiment, such as… Figure 4 As shown, the measurement host 11 includes a control module 111, a time difference calculation module 112, and a flow rate calculation module 113.

[0049] The control module 111 controls the ultrasonic wave transmission and reception of each first ultrasonic transducer 121 and each second ultrasonic transducer 122. The time difference calculation module 112 calculates each first time difference of ultrasonic wave transmission from each first ultrasonic transducer 121 to each corresponding second ultrasonic transducer 122, or each second time difference of ultrasonic wave transmission from each second ultrasonic transducer 122 to each corresponding first ultrasonic transducer 121. The flow rate calculation module 113 determines the flow rate of the fluid under test based on each first time difference or each second time difference.

[0050] The measurement host also includes a data reading and storage module (not shown in the figure), a setting module (not shown in the figure), and a data processing module (not shown in the figure). The data reading and storage module is used to store and read historical flow data within a preset time period. The setting module is used to set the flow channel measurement parameters.

[0051] Through the above embodiments, the technical solution of this application ultimately achieves flow velocity measurement through different functional modules of the measurement host. Different functional modules independently control different groups of ultrasonic transducers, and by comprehensively processing the flow velocities measured by different groups of ultrasonic transducers, a more accurate flow velocity is obtained, thereby improving the measurement accuracy.

[0052] According to some embodiments of this application, the fixing member 17 is a rigid connecting rod, the rigid connecting rod is provided with a locking member, and the rigid connecting rod is connected to the outer wall of each auxiliary measuring member 13, which is provided with an ultrasonic transducer, through the locking member.

[0053] Through the above embodiments, the technical solution of this application, by designing the fixing member as a rigid connecting rod, can suppress mechanical vibration during the measurement process of the portable vertical multilayer ultrasonic flow measuring device, thereby reducing the measurement error caused by mechanical vibration and improving the measurement accuracy.

[0054] According to some embodiments of this application, the fixing member includes at least two sub-fixing members. Each sub-fixing member is connected to the outer wall of the ultrasonic transducer of each auxiliary measuring member. Figure 5 A schematic diagram of the structure of a sub-fixing member according to an embodiment of this application is shown. According to an example embodiment, such as… Figure 5 As shown, the sub-fixing member 171 is provided with a telescopic adjustment member 1711, which is used to adjust the distance between adjacent sub-fixing members 171.

[0055] For example, the telescopic adjustment member 1711 may include a screw and a nut. The spacing between adjacent sub-fixing members 171 is adjusted by mutually adapting screws and nuts disposed on the telescopic adjustment member 1711.

[0056] Through the above embodiments, the technical solution of this application realizes the adjustable function of the distance between adjacent measurement units by setting the fixing member as at least two sub-fixing members with adjustable mutual spacing, thereby adapting to the measurement needs of different water depths or flow velocity sections, thereby improving the scalability and accuracy of measurement.

[0057] According to some embodiments of this application, the cross-section of the rigid connecting rod is rectangular.

[0058] Through the above embodiments, the technical solution of this application improves the firmness of the fastener by designing the cross-section of the fastener as rectangular, utilizing the fact that the bending section modulus of the rectangular cross-section is significantly higher than that of the circular cross-section.

[0059] According to some embodiments of this application, such as Figure 3 As shown, the auxiliary measuring component 13 is provided with a first mounting hole (not shown in the figure) and a second mounting hole (not shown in the figure). The first ultrasonic transducer 121 is fixed in the first mounting hole, and the second ultrasonic transducer 122 is fixed in the second mounting hole.

[0060] For example, the first ultrasonic transducer 121 and the second ultrasonic transducer 122 can both be fixed to the mounting holes of the auxiliary measuring component 13 by welding or glue.

[0061] Through the above embodiments, the technical solution of this application fixes the first ultrasonic transducer and the second ultrasonic transducer by a dual-control installation method, thereby realizing the installation of the two ultrasonic transducers and forming a stable ultrasonic propagation path transmission and reception angle, thereby improving the stability of the measurement process of the portable vertical multilayer ultrasonic flow measurement device.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features.
