[0044] Please refer to Figure 1 and Figure 2The embodiment of the present application provides an ultrasonic flowmeter integrated device 10, which comprises a fixing assembly 110, a first ultrasonic probe assembly 120 and a second ultrasonic probe assembly 120a. The fixing assembly 110 comprises a fixing frame 111 and a fixing piece 112. The fixing piece 112 is arranged on the fixing frame 111 and is used for fixing the fixing frame 111 to a pipeline to be measured (not shown in the figure). The first ultrasonic probe assembly 120 is arranged on the fixing frame 111. The second ultrasonic probe assembly 120a is arranged opposite to the first ultrasonic probe assembly 120 and is slidingly arranged on the fixing frame 111.

[0045] The ultrasonic flowmeter integrated device 10 provided by the embodiment of the present application comprises a fixing assembly 110, a first ultrasonic probe assembly 120 and a second ultrasonic probe assembly 120a. The fixing assembly 110 comprises a fixing frame 111 and a fixing piece 112. The fixing piece 112 is used for fixing the fixing frame 111 to a pipeline to be measured. The first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a are arranged opposite to each other and are arranged on the fixing frame 111. The second ultrasonic probe assembly 120a is slidingly arranged on the fixing frame 111. In this way, when measuring the flow of the pipeline to be measured, the fixing frame 111 is fixed to the pipeline to be measured through the fixing piece 112, so that the entire ultrasonic flowmeter integrated device 10 can be fixed to the pipeline to be measured. The distance between the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a can be adjusted by sliding the second ultrasonic probe assembly 120a on the fixing frame 111. The flow of the pipeline to be measured can be quickly measured through the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a. In summary, the ultrasonic flowmeter integrated device 10 has the advantages of convenient installation and quick measurement, can overcome the problems of complicated installation and high installation cost of the existing ultrasonic flowmeter, and can reduce the installation cost and the flow measurement cost of the device.

[0046] In some embodiments, referring to Figure 3 and Figure 5 , the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a each comprise a mounting frame 121, an ultrasonic probe 122 and a moving piece 123. The ultrasonic probe 122 is connected with the moving piece 123. The moving piece 123 is arranged on the mounting frame 121 and is used for driving the ultrasonic probe 122 to approach or move away from the pipeline to be measured. The mounting frame 121 of the first ultrasonic probe assembly 120 is fixed to the fixing frame 111. The mounting frame 121 of the second ultrasonic probe assembly 120a is slidingly arranged on the fixing frame 111.

[0047] Thus, the ultrasonic probe 122 can be conveniently supported and arranged above the fixed frame 111 through the mounting frame 121, and the ultrasonic probe 122 is driven to approach or move away from the to-be-measured pipeline through the moving piece 123. In the flow measurement, the ultrasonic probe 122 can be conveniently attached to the wall of the to-be-measured pipeline, the flow measurement in the to-be-measured pipeline is realized through the ultrasonic probe 122, and the accuracy of the flow measurement is improved. After the flow measurement is completed, the ultrasonic probe 122 can be conveniently moved away from the to-be-measured pipeline, so that the entire device is transferred, and the ultrasonic probe 122 is prevented from colliding with the to-be-measured pipeline in the transfer process.

[0048] In some embodiments, referring to Figure 3 and Figure 5 , the moving piece 123 comprises a lead screw 1231, a nut (not shown in the figure), a connecting frame 1232 and a first driving piece 1233. The lead screw 1231 is arranged on the mounting frame 121, the nut is threadedly connected to the lead screw 1231, the connecting frame 1232 is connected to the nut, and the ultrasonic probe 122 is connected to the connecting frame 1232. The first driving piece 1233 is connected to the lead screw 1231, and the first driving piece 1233 is used to drive the lead screw 1231 to rotate.

[0049] Thus, when the ultrasonic probe 122 is driven to approach or move away from the to-be-measured pipeline through the moving piece 123, the lead screw 1231 can be driven to rotate through the first driving piece 1233, the nut on the lead screw 1231 is driven to move along the axis direction of the lead screw 1231, thereby driving the connecting frame 1232 and the ultrasonic probe 122 connected to the connecting frame 1232 to move, so that the ultrasonic probe 122 approaches or moves away from the to-be-measured pipeline. In turn, the flow measurement in the to-be-measured pipeline can be conveniently realized, the entire ultrasonic flowmeter integrated device 10 is conveniently transferred, and the ultrasonic probe 122 is prevented from colliding with the to-be-measured pipeline in the transfer process.

[0050] In a specific example, the first driving piece 1233 can be a driving motor, and the first driving piece 1233 can be arranged on the mounting frame 121. The output end of the driving motor is connected to the lead screw 1231 to drive the lead screw 1231 to rotate.

[0051] In some embodiments, referring to Figure 2 , Figure 5 and Figure 6 , the ultrasonic flowmeter integrated device 10 further comprises a guide assembly 130 and a second driving piece 140. The guide assembly 130 comprises a guide piece 131 and a sliding piece 132. The guide piece 131 is arranged on the fixed frame 111, and the sliding piece 132 is slidingly connected to the guide piece 131. The mounting frame 121 of the second ultrasonic probe assembly 120a is connected to the sliding piece 132. The second driving piece 140 is connected to the sliding piece 132, and the second driving piece 140 is used to drive the sliding piece 132 to slide along the guide piece 131.

[0052] Thus, when the distance between the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a needs to be adjusted, the sliding member 132 is driven to slide along the guide member 131 by the second driving member 140, the mounting rack 121 of the second ultrasonic probe assembly 120a is driven to move, and thus the second ultrasonic probe assembly 120a is driven to move, so as to automatically adjust the distance between the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a, and thus the automation degree of the ultrasonic flowmeter integrated device 10 can be improved, and the measurement efficiency and the measurement accuracy of the ultrasonic flowmeter integrated device 10 can be improved.

[0053] In one specific example, the guide member 131 can be two slide rails arranged in parallel on the fixed rack 111, the sliding member 132 can be two sliding blocks, the two sliding blocks correspond to the two slide rails one by one, the sliding blocks are slidingly connected to the corresponding slide rails, and the two sliding blocks are connected to the mounting rack 121; the second driving member 140 can be a linear driving member, for example, a pneumatic cylinder; the second driving member 140 can be one or two.

[0054] In another specific example, referring to Figure 6 , the guide member 131 can be two slide rails arranged in parallel on the fixed rack 111, the sliding member 132 can be two pulleys, the two pulleys correspond to the two slide rails one by one, and the pulleys can roll along the corresponding slide rails; the two pulleys are spaced apart and rotatably connected to the mounting rack 121; the second driving member 140 includes two driving motors, the two driving motors are arranged on the mounting rack 121, the two driving motors correspond to the two pulleys one by one, and each driving motor is used to drive the corresponding pulley to roll along the corresponding slide rail.

[0055] In some embodiments, referring to Figure 4 and Figure 6 , the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a each further include an injection member 124; the mounting rack 121 is provided with an injection channel 1211; the injection member 124 is arranged on the mounting rack 121, the injection member 124 communicates with the injection channel 1211, and the injection member 124 is used to inject a coupling agent into the injection channel 1211; the mounting rack 121 is provided with an outlet 1212 communicating with the injection channel 1211, and the outlet 1212 is used to guide the coupling agent injected by the injection member 124 into the injection channel 1211 to the pipeline to be measured.

[0056] Thus, the distance between the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a is adjusted to be in place, and the ultrasonic probe 122 is driven to be close to the pipeline to be measured by the moving piece 123. The injection member 124 can be used to inject the coupling agent into the injection channel 1211, and the coupling agent in the injection channel 1211 is guided to the pipeline to be measured through the outlet 1212 on the mounting bracket 121. Thus, when the ultrasonic probe 122 is driven to be close to the pipeline to be measured by the moving piece 123, the ultrasonic probe 122 can be in contact with the wall of the pipeline to be measured through the coupling agent, so as to improve the accuracy of the measurement data.

[0057] In some embodiments, referring to Figure 4 and Figure 6 , the injection member 124 includes an injection pump 1241 and an injector 1242. The injector 1242 is in communication with the injection channel 1211, and the injection pump 1241 is arranged on the mounting bracket 121. The injection pump 1241 is connected with the injector 1242, and the injection pump 1241 is used to drive the injector 1242 to inject the coupling agent into the injection channel 1211.

[0058] Thus, by arranging the injection pump 1241 and the injector 1242, the coupling agent can be conveniently injected into the injection channel 1211, and the automation of the injection of the coupling agent is realized, so as to improve the automation degree of the ultrasonic flowmeter integrated device 10 and improve the working efficiency of the ultrasonic flowmeter integrated device 10.

[0059] In a specific example, the injector 1242 can be an injection needle tube. The injector 1242 is detachably connected with the injection channel 1211 and the injection pump 1241. Thus, the injector 1242 can conveniently suck the coupling agent.

[0060] In some embodiments, referring to Figure 5 and Figure 6 , the ultrasonic flowmeter integrated device 10 further includes a distance measuring assembly 150 arranged on the mounting bracket 121 of the first ultrasonic probe assembly 120 or the mounting bracket 121 of the second ultrasonic probe assembly 120a. The distance measuring assembly 150 is used to monitor the distance between the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a.

[0061] Thus, by the distance measuring assembly 150, the distance between the first ultrasonic probe assembly 120 and the second ultrasonic probe assembly 120a can be quickly adjusted, so as to improve the measurement efficiency and the measurement accuracy of the ultrasonic flowmeter integrated device 10.

[0062] In some embodiments, the distance measuring assembly 150 includes a distance measuring sensor, such as a laser distance measuring sensor or an infrared distance measuring sensor.

[0063] In some embodiments, refer to Figure 1 and Figure 2 The fixing member 112 comprises a plurality of electromagnet bases 1121 which are arranged on the fixing frame 111 at intervals.

[0064] The pipeline to be measured is usually a metal pipeline. In the present embodiment, the fixing member 112 comprises a plurality of electromagnet bases 1121. The fixing frame 111 can be fixed on the pipeline to be measured by using the attractive force between the electromagnet bases 1121 and the pipeline to be measured. The ultrasonic flowmeter integrated device 10 is fixed on the pipeline to be measured. In addition, the on-off of the electromagnet bases 1121 can be controlled to control whether the electromagnet bases 1121 have magnetic attraction force, so that the installation and disassembly of the ultrasonic flowmeter integrated device 10 can be facilitated.

[0065] In some embodiments, refer to Figure 1 and Figure 2 The ultrasonic flowmeter integrated device 10 further comprises a controller 160 and a power supply 170. The power supply 170 is electrically connected with the fixing member 112, the first ultrasonic probe assembly 120, the second ultrasonic probe assembly 120a, the second driving member 140 and the controller 160. The controller 160 is electrically connected with the first ultrasonic probe assembly 120, the second ultrasonic probe assembly 120a and the second driving member 140.

[0066] In this way, the fixing member 112, the first ultrasonic probe assembly 120, the second ultrasonic probe assembly 120a, the second driving member 140 and the controller 160 can be powered by the power supply 170 to ensure the normal operation of the fixing member 112, the first ultrasonic probe assembly 120, the second ultrasonic probe assembly 120a, the second driving member 140 and the controller 160. The first ultrasonic probe assembly 120, the second ultrasonic probe assembly 120a and the second driving member 140 can be controlled by the controller 160 to operate, so as to realize the automatic measurement of the flow of the pipeline to be measured, greatly reduce the cost of manpower and material resources, and improve the measurement efficiency and accuracy.

[0067] In some embodiments, the ultrasonic flowmeter integrated device 10 further comprises a mobile terminal (not shown in the figure). A wireless communication module (not shown in the figure) is arranged in the controller 160. The controller 160 is in communication connection with the mobile terminal through the wireless communication module. A parameter setting module is arranged in the mobile terminal. The parameter setting module is used for setting the parameters of the pipeline to be measured and the ultrasonic parameters.

[0068] Thus, by providing the wireless communication module in the controller 160, the controller 160 is in communication connection with the mobile terminal through the wireless communication module, so that the ultrasonic flowmeter integrated device 10 can be remotely controlled through the mobile terminal, the number of operating personnel required during flow measurement is reduced, and the ultrasonic flowmeter integrated device 10 can work in a small area. In addition, by providing the parameter setting module in the mobile terminal, the parameters of the pipeline to be measured and the ultrasonic parameters can be set through the parameter setting module, so that the controller 160 can control the operation of the first ultrasonic probe assembly 120, the second ultrasonic probe assembly 120a and the second driving member 140 according to the parameters of the pipeline to be measured and the ultrasonic parameters, thereby improving the measurement efficiency and accuracy of the ultrasonic flowmeter integrated device 10.

[0069] In a specific example, the mobile terminal can be a display device with a display screen, such as a mobile phone.

[0070] In some embodiments, the parameters of the pipeline to be measured include the outer diameter, wall thickness, material, lining material and thickness, fluid medium in the pipeline to be measured, medium temperature and the like; the ultrasonic parameters include the refraction mode of the ultrasonic wave, and the refraction mode of the ultrasonic wave includes "V" shape or "W" shape. The controller 160 is also connected with the distance measuring assembly 150, and the controller 160 can be used to calculate the theoretical distance between the first ultrasonic probe assembly 120 and the first ultrasonic probe assembly 120 according to the parameters of the pipeline to be measured, and to control the operation of the second driving member 140 according to the theoretical distance and the actual distance measured by the distance measuring assembly 150, so as to adjust the distance between the first ultrasonic probe assembly 120 and the first ultrasonic probe assembly 120 to the theoretical distance, thereby improving the flow measurement accuracy. The controller 160 is also used to control the ultrasonic refraction mode of the first ultrasonic probe assembly 120 and the first ultrasonic probe assembly 120 according to the ultrasonic parameters, so that the ultrasonic flowmeter integrated device 10 is suitable for flow measurement of different fluid media.

[0071] In some embodiments, the controller 160 is also used to control the operation of the second driving member 140 according to the absolute value of the difference between the actual distance measured by the distance measuring assembly 150 and the theoretical distance. Thus, the moving speed of the second ultrasonic probe assembly 120a can be conveniently controlled, so as to adjust the distance between the first ultrasonic probe assembly 120 and the first ultrasonic probe assembly 120 to the theoretical distance, thereby improving the flow measurement accuracy.

[0072] Specifically, when the absolute value of the difference between the actual distance measured by the distance measuring assembly 150 and the theoretical distance is greater than 50 mm, the controller 160 controls the second driving member 140 to operate so that the second ultrasonic probe assembly 120a moves at a speed of 50 mm / s; when the absolute value of the difference between the actual distance measured by the distance measuring assembly 150 and the theoretical distance is between 10 mm and 50 mm, the controller 160 controls the second driving member 140 to operate so that the second ultrasonic probe assembly 120a moves at a speed of 20 mm / s; and when the absolute value of the difference between the actual distance measured by the distance measuring assembly 150 and the theoretical distance is less than 10 mm, the controller 160 controls the second driving member 140 to operate so that the second ultrasonic probe assembly 120a moves at a speed of 2 mm / s.

[0073] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, but it should be understood that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.
