[0002] Conventional vortex flowmeters include a measuring tube and an inserted measuring device placed in the measuring tube. The inserted device forms a fluid measurement space, and there is a disturbing fluid in the measuring tube that can generate disturbances.

[0019] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Additionally, the features described for some examples can be combined in other examples.

[0020] As Figures 1-6 shown, a multi-point intelligent vortex flowmeter includes: A plurality of pipe hoop positioning mechanisms 1, which are used for detachably connecting with a pipeline, and the pipe hoop positioning mechanisms 1 are installed at corresponding perforations on the pipeline; A plurality of protection mechanisms 2, which are respectively arranged on the corresponding pipe hoop positioning mechanisms 1, and an isolation buffer mechanism 3 is connected inside the protection mechanism 2; A plurality of monitoring modules 4, which are respectively arranged in the corresponding protection mechanisms 2, and the monitoring modules 4 are detachably connected with the corresponding isolation buffer mechanisms 3; A terminal 6, on which a plurality of conducting wires 5 are connected, and the plurality of conducting wires 5 are respectively electrically connected with the corresponding monitoring modules 4; The isolation buffer mechanism 3 includes a limit component connected to the inner wall of the protection mechanism 2, a telescopic isolation component I movably connected to the limit component, and a telescopic isolation component II movably connected to the other end of the telescopic isolation component I. When the telescopic isolation component I rotates by a set angle, one end thereof communicates with a corresponding perforation on the pipeline through the limit component. When the telescopic isolation component II rotates by a set angle, the internal space thereof communicates with the internal space of the telescopic isolation component I. The monitoring module 4 is detachably connected to the other end of the telescopic isolation component II. When the monitoring module 4 is connected to the other end of the telescopic isolation component II, the other end of the telescopic isolation component II is in a sealed state.

[0021] It should be noted that when reconstructing an old pipeline, a perforation is drilled at a corresponding point of the old pipeline, and then the hoop pipe positioning mechanism 1 is installed at the corresponding perforation. Then, the corresponding monitoring module 4 is connected to the isolation buffer mechanism 3 in the protection mechanism 2. Initially, the old pipeline is in a shut-off state. At this time, the telescopic isolation component I and the telescopic isolation component II can be directly rotated to a state of mutual communication. At this time, the telescopic isolation component I, the telescopic isolation component II, the limit component, and the corresponding perforation on the old pipeline are all in a communicating state. At this time, the monitoring module 4 can be directly connected to the telescopic isolation component II, and then the telescopic isolation component I and the telescopic isolation component II are limited and fixed at a set position on the limit component. At this time, the corresponding detection part on the monitoring module 4 can be inserted into the old pipeline for flow monitoring, and the perforation is in a sealed state. In this way, synchronous monitoring can be carried out at multiple points on the old pipeline, effectively reducing data errors and improving the accuracy of flow monitoring data. When there is fluid in the pipeline and it is flowing continuously, when disassembling and subsequently installing the monitoring module 4, the specific process is as follows. First, detach the telescopic isolation component II and the telescopic isolation component I from the limiting component. At this time, both the telescopic isolation component II and the telescopic isolation component I are in a stretchable state. Control the monitoring module 4 to move upward and simultaneously stretch the telescopic isolation component II and the telescopic isolation component I, so that the monitoring module 4 is completely detached from the pipeline. At this time, the telescopic isolation component II and the telescopic isolation component I can be rotated synchronously, so that one end of the telescopic isolation component I and the limiting component are adjusted to a closed state. At this time, continue to pull the telescopic isolation component II and the telescopic isolation component I until the monitoring module 4 completely enters the internal space of the telescopic isolation component II. At this time, all the fluid existing in the telescopic isolation component II and the telescopic isolation component I is deposited inside the telescopic isolation component I. Then, the telescopic isolation component I can be fixed. Only rotate the telescopic isolation component II so that one end of the telescopic isolation component II and the other end of the telescopic isolation component I are adjusted to a closed state. Subsequently, the monitoring module 4 can be detached from the telescopic isolation component II. Then, rotate the telescopic isolation component II and the telescopic isolation component I synchronously, so that one end of the telescopic isolation component I and the limiting component are adjusted to a conducting state, and there is still a closed state between the other end of the telescopic isolation component I and one end of the telescopic isolation component II. At this time, the telescopic isolation component II and the telescopic isolation component I can be compressed, so that most of the fluid in the telescopic isolation component I is pressed back into the pipeline again; When reinstalling the monitoring module 4, adjust one end of the telescopic isolation component I and the limiting component to a closed state, adjust to a conducting state between the other end of the telescopic isolation component I and one end of the telescopic isolation component II, and stretch the telescopic isolation component I and the telescopic isolation component II again. After connecting the monitoring module 4 to the telescopic isolation component II, adjust one end of the telescopic isolation component I and the limiting component to a conducting state, and then the monitoring module 4 can be inserted into the pipeline again. During the entire disassembly and installation process, it can be ensured that the fluid in the pipeline will not leak, and the fluidity of the fluid in the pipeline can be guaranteed.

[0022] In an optional embodiment of the present invention, as Figure 2 and Figure 6 shown, the pipe hoop positioning mechanism 1 includes a semi-circular hoop pipe fitting I 101, a semi-circular hoop pipe fitting II 102 detachably connected to the semi-circular hoop pipe fitting I 101, a through hole I provided on the semi-circular hoop pipe fitting II 102, and a seal 103 connected at the through hole I. The through hole I is arranged to match a corresponding perforation on the pipeline. The seal 103 is inserted into the corresponding perforation on the pipeline, and a plastic seal body is provided between the outer wall of the seal 103 and the inner wall of the corresponding perforation on the pipeline.

[0023] It should be noted that, as described above, when installing the hoop pipe positioning mechanism 1 at the corresponding positions on the old pipeline, the semi-circular hoop pipe fitting one 101 and the semi-circular hoop pipe fitting two 102 are clamped on the old pipeline, and it is ensured that the through hole one on the semi-circular hoop pipe fitting two 102 can correspond to the corresponding perforation on the old pipeline, and it is ensured that the seal 103 can be inserted into the perforation. Then, the semi-circular hoop pipe fitting one 101 and the semi-circular hoop pipe fitting two 102 are connected by connecting bolts, so that the semi-circular hoop pipe fitting one 101 and the semi-circular hoop pipe fitting two 102 form a complete ring body and are tightly clamped on the old pipeline, and the gap between the seal 103 and the perforation can be tightly sealed by a plastic sealing body.

[0024] In an alternative embodiment of the present invention, as shown in the figure, the plastic sealing body includes a plastic washer, the outer circumferential surface of the plastic washer is in close contact with the inner wall of the corresponding perforation on the pipeline, and its inner circumferential surface is in close contact with the outer wall of the seal 103.

[0025] It should be noted that, as described above, when the plastic sealing body adopts a plastic washer, as the seal 103 is inserted into the perforation, the plastic washer is gradually compressed and deformed, so that the gap between the seal 103 and the perforation is tightly sealed.

[0026] In an alternative embodiment of the present invention, the plastic sealing body includes a plastic capsule, a cavity provided inside the semi-circular hoop pipe fitting two 102, and a one-way valve provided in the cavity. One end of the cavity is communicated with the internal space of the plastic capsule, and the other end is communicated with the outside. The one-way valve is used to limit the fluid to only flow from the outside to the plastic capsule.

[0027] It should be noted that, as described above, when the plastic sealing body adopts a plastic capsule, fluid can be introduced externally and unidirectionally introduced into the plastic capsule, so that the pressure inside the plastic capsule changes, thereby realizing the sealing of the gap between the seal 103 and the perforation. At the same time, the pressure inside the plastic capsule can be adjusted according to the fluid pressure inside the pipeline, so as to prevent the situation that the plastic capsule deforms under high pressure and causes the fluid inside the pipeline to leak.

[0028] In an alternative embodiment of the present invention, as Figure 2 and Figure 3 shown, the protection mechanism 2 includes a fixed protection shell 201, an installation groove provided inside the fixed protection shell 201, a through hole two provided at the bottom of the installation groove, and a movable protection shell 202 detachably connected to the fixed protection shell 201. The installation groove is communicated with the corresponding perforation on the pipeline through the through hole two, and the fixed protection shell 201 is fixedly connected to the semi-circular hoop pipe fitting two 102.

[0029] It should be noted that when installing the monitoring module 4, the movable protective shell 202 can be detached from the fixed protective shell 201. After the installation is completed, the movable protective shell 202 can be reconnected to the fixed protective shell 201, which can provide stable protection for the monitoring module 4.

[0030] In an alternative embodiment of the present invention, as Figures 3-6 shown, the limiting component includes a number of uniformly distributed fixing screws 301, a first partition plate 302, a number of through holes three provided at the middle position of the first partition plate 302, a number of limiting holes one provided at the edge position of the first partition plate 302, and a number of nuts one 3020 movably connected to the first partition plate 302. The number of nuts one 3020 are coaxially arranged with the number of limiting holes one respectively, the number of limiting holes one are correspondingly arranged with the number of fixing screws 301 respectively, the number of nuts one 3020 are threadedly connected to the number of fixing screws 301 respectively, and the number of fixing screws 301 are all fixedly connected to the bottom of the installation groove.

[0031] The telescopic isolation component one includes a second partition plate 303, a number of through holes four provided at the middle position of the second partition plate 303, a telescopic threaded tube one 304 fixedly connected to the second partition plate 303, a third partition plate 305 fixedly connected to the other end of the telescopic threaded tube one 304, a number of limiting plates one 3050 fixedly connected to the outer circumferential surface of the third partition plate 305, a limiting hole two provided on the limiting plate one 3050, a nut two 3051 movably connected to the limiting plate one 3050, and a number of through holes five provided at the middle position of the third partition plate 305. The nut two 3051 is coaxially arranged with the limiting hole two, the limiting hole two is correspondingly arranged with the fixing screw 301, the nut two 3051 is threadedly connected to the fixing screw 301, the number of through holes five and through holes four are correspondingly arranged with the number of through holes three respectively, the second partition plate 303 is movably connected to the first partition plate 302, and the second partition plate 303 is in close contact with the first partition plate 302.

[0032] The telescopic isolation component two includes a fourth partition plate 306, a number of through holes six provided at the middle position of the fourth partition plate 306, a telescopic threaded tube two 307 fixedly connected to the fourth partition plate 306, a connecting ring body 308 fixedly connected to the other end of the telescopic threaded tube two 307, a number of limiting plates two 3080 fixedly connected to the outer circumferential surface of the connecting ring body 308, a limiting hole three provided on the limiting plate two 3080, and a nut three 3081 movably connected to the limiting plate two 3080. The nut three 3081 is coaxially arranged with the limiting hole three, the limiting hole three is correspondingly arranged with the fixing screw 301, the nut three 3081 is threadedly connected to the fixing screw 301, the number of through holes six is correspondingly arranged with the number of through holes five, the fourth partition plate 306 is movably connected to the third partition plate 305, and the fourth partition plate 306 is in close contact with the third partition plate 305.

[0033] The monitoring module 4 includes a circuit integration module 401, a turbulator 402 connected to the circuit integration module 401, and a detecting member. The detecting member is electrically connected to the circuit integration module 401, and the circuit integration module 401 is electrically connected to the terminal 6 through a wire 5. The turbulator 402 and the detecting member are both prior arts and will not be elaborated here.

[0034] The circuit integration module 401 is detachably connected to the connecting ring body 308. When the circuit integration module 401 and the connecting ring body 308 are in a connected state, the opening of the connecting ring body 308 is in a sealed state.

[0035] It should be noted that, as described above, when disassembling and subsequently installing the monitoring module 4, the specific process is as follows. First, rotate nut three 3081 and nut two 3051 so that nut three 3081 and nut two 3051 are disengaged from the fixing screw 301, and drive the second limiting plate 3080 and the first limiting plate 3050 to synchronously disengage from the fixing screw 301. When the first limiting plate 3050 and the second limiting plate 3080 are disengaged from the fixing screw 301, the third partition plate 305 and the connecting ring body 308 can start to rotate. When the connecting ring body 308 rotates, it can drive the fourth partition plate 306 to rotate synchronously through the telescopic threaded pipe two 307. When the third partition plate 305 rotates, it can drive the second partition plate 303 to rotate synchronously through the telescopic threaded pipe one 304, and both the telescopic threaded pipe two 307 and the telescopic threaded pipe one 304 are in a stretchable state. At this time, the control circuit integration module 401 moves upward. The circuit integration module 401 can drive the connecting ring body 308 to move upward synchronously, and stretch the fourth partition plate 306 and the telescopic threaded pipe one 304, so that the monitoring module 4 is completely separated from the pipeline. At this time, the connecting ring body 308 and the third partition plate 305 can be rotated synchronously, so that a plurality of through holes four on the second partition plate 303 and a plurality of through holes three on the fixing screw 301 are adjusted from a completely overlapping state to a completely non-overlapping state. At this time, both the through hole three and the through hole four are in a closed state. At this time, continue to pull the monitoring module 4 until the turbulator 402 and the detecting element completely enter the space between the fourth partition plate 306, the telescopic threaded pipe two 307, the connecting ring body 308 and the circuit integration module 401. At this time, all the fluid existing in the space between the fourth partition plate 306, the telescopic threaded pipe two 307, the connecting ring body 308 and the circuit integration module 401 flows into the space formed between the second partition plate 303, the telescopic threaded pipe one 304 and the third partition plate 305 from the through hole six and the through hole five. At this time, fix the third partition plate 305 and only rotate the connecting ring body 308 so that a plurality of through holes six on the fourth partition plate 306 and a plurality of through holes five on the third partition plate 305 are adjusted from a completely overlapping state to a completely non-overlapping state. Subsequently, the circuit integration module 401 can be disengaged from the connecting ring body 308. Then, the connecting ring body 308 and the third partition plate 305 are rotated synchronously so that the through hole four and the through hole three are readjusted to a conducting state, and the through hole six and the through hole five are still in a closed state. At this time, the connecting ring body 308 can be compressed so that most of the fluid in the space formed between the second partition plate 303, the telescopic threaded pipe one 304 and the third partition plate 305 is pressed back into the pipeline again; When reinstalling the monitoring module 4, adjust through hole four and through hole three to the closed state, adjust through hole six and through hole five to the conducting state, and re-stretch the telescopic threaded tube two 307 and the telescopic threaded tube one 304. After reinserting the turbulence generating element 402 and the detecting element into through hole six and through hole five, reconnect the circuit integration module 401 to the connecting ring body 308, and adjust through hole four and through hole three to the conducting state, then the turbulence generating element 402 and the detecting element can be reinserted into the pipeline again. During the entire disassembly and installation process, it can be ensured that the fluid in the pipeline will not leak, and the fluidity of the fluid in the pipeline can be guaranteed.

[0036] The above has described the present embodiment, but the present embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive.
