Description

Technical Field

[0001] This invention relates to the field of intelligent pipeline flow sensor technology, and more specifically, to a multi-point intelligent vortex flow meter. Background Technology

[0002] A conventional vortex flow meter includes a measuring tube and an insertion measuring device placed inside the measuring tube. The insertion device forms a fluid measurement space, and there is a turbulent fluid in the measuring tube that can generate disturbance. A detection device for detecting disturbance is arranged around the turbulent fluid. The detection device and the turbulent fluid are inserted through an opening in the measuring tube.

[0003] To improve the applicability of vortex flow meters, insertion-type vortex flow meters were developed. These are mainly used in old pipeline monitoring and renovation projects to reduce pipeline renovation costs. The existing turbulence is designed as an external structure. During use, the turbulence is installed into the perforation opened on the old pipeline by plugging it in. It is a movable and detachable design.

[0004] However, some unstable factors may interfere with the operation of the vortex flow meter during installation, resulting in a decrease in the accuracy of the monitoring data of a single vortex flow meter. This makes it unsuitable for some high-precision pipeline flow monitoring projects. Moreover, during troubleshooting and replacement of the flow meter, it is necessary to cut off the flow in the pipeline, which can easily cause economic losses. Summary of the Invention

[0029] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0030] like Figures 1-6 As shown, a multi-point intelligent vortex flow meter includes:

[0031] Several clamp positioning mechanisms 1 are provided. The clamp positioning mechanisms 1 are used for detachable connection with the pipe and are installed at the corresponding perforation on the pipe.

[0032] Several protective mechanisms 2 are respectively installed on the corresponding clamp positioning mechanism 1, and an isolation buffer mechanism 3 is connected inside the protective mechanism 2;

[0033] Several monitoring modules 4 are respectively installed in the corresponding protective mechanism 2, and the monitoring modules 4 are detachably connected to the corresponding isolation buffer mechanism 3.

[0034] Terminal 6, with several wires 5 connected to it, and the wires 5 are electrically connected to the corresponding monitoring modules 4 respectively;

[0035] The isolation buffer mechanism 3 includes a limiting component connected to the inner wall of the protective mechanism 2, a telescopic isolation component one movably connected to the limiting component, and a telescopic isolation component two movably connected to the other end of the telescopic isolation component one. When the telescopic isolation component one rotates to a set angle, one end of it is connected to a corresponding perforation on the pipe through the limiting component. When the telescopic isolation component two rotates to a set angle, its internal space is connected to the internal space of the telescopic isolation component one. The monitoring module 4 is detachably connected to the other end of the telescopic isolation component two. When the monitoring module 4 is connected to the other end of the telescopic isolation component two, the other end of the telescopic isolation component two is in a sealed state.

[0036] It should be noted that when modifying an old pipeline, perforations are drilled at the corresponding points on the old pipeline. Then, the clamp 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 flow interruption state. At this time, the telescopic isolation component 1 and the telescopic isolation component 2 can be rotated to a mutually connected state. At this time, the telescopic isolation component 1, the telescopic isolation component 2, the limiting component, and the corresponding perforations on the old pipeline are all in a connected state. At this time, the monitoring module 4 can be directly connected to the telescopic isolation component 2. Then, the telescopic isolation component 1 and the telescopic isolation component 2 are limited and fixed at the set position on the limiting component. At this time, the corresponding detection part on the monitoring module 4 can be inserted into the old pipeline for flow monitoring. The perforation is in a sealed state. In this way, multiple points on the old pipeline can be monitored simultaneously, effectively reducing data errors and improving the accuracy of flow monitoring data.

[0037] When fluid is present and continuously flowing in the pipeline, the disassembly and subsequent installation of monitoring module 4 are performed as follows: First, detach telescopic isolation components two and one from the limiting component. At this time, both telescopic isolation components two and one are in a stretchable state. Control the monitoring module 4 to move upward, and simultaneously stretch telescopic isolation components two and one, so that the monitoring module 4 is completely detached from the pipeline. At this time, telescopic isolation components two and one can be rotated simultaneously, so that one end of telescopic isolation component one is adjusted to a closed state with the limiting component. Then, continue to pull telescopic isolation components two and one until the monitoring module 4 is completely inside the internal space of telescopic isolation component two. At this time, the fluid present in telescopic isolation components two and one... The entire fluid is stored inside the first telescopic isolation component, which can then be fixed in place. Only the second telescopic isolation component is rotated to adjust one end of the second telescopic isolation component to a closed state with the other end of the first telescopic isolation component. Then, the monitoring module 4 can be detached from the second telescopic isolation component. Then, the second and first telescopic isolation components are rotated simultaneously to adjust one end of the first telescopic isolation component and the limiting component to a conductive state. The other end of the first telescopic isolation component and one end of the second telescopic isolation component remain closed. At this point, the second and first telescopic isolation components can be compressed, causing most of the fluid inside the first telescopic isolation component to be forced back into the pipeline.

[0038] When reinstalling monitoring module 4, adjust one end of telescopic isolation component one and the limiting component to the closed state, and adjust the other end of telescopic isolation component one and one end of telescopic isolation component two to the conductive state. Then, stretch telescopic isolation component one and telescopic isolation component two again, connect monitoring module 4 to telescopic isolation component two, and adjust one end of telescopic isolation component one and the limiting component to the conductive state. Then, re-insert monitoring module 4 into the pipeline. Throughout the entire disassembly and installation process, it can be ensured that the fluid in the pipeline will not leak out, thus ensuring the fluidity of the fluid in the pipeline.

[0039] In an optional embodiment of the invention, such as Figure 2 and Figure 6 As shown, the clamp positioning mechanism 1 includes a semi-annular clamp component 101, a semi-annular clamp component 2 102 detachably connected to the semi-annular clamp component 101, a through hole 1 provided on the semi-annular clamp component 2 102, and a sealing element 103 connected to the through hole. The through hole 1 is matched with the corresponding perforation on the pipe. The sealing element 103 is inserted into the corresponding perforation on the pipe, and a plastic sealing body is provided between the outer wall of the sealing element 103 and the inner wall of the corresponding perforation on the pipe.

[0040] It should be noted that, as mentioned above, when the clamp positioning mechanism 1 is installed at the corresponding point on the old pipeline, the semi-annular clamp component 101 and the semi-annular clamp component 202 are clamped onto the old pipeline, ensuring that the through hole 1 on the semi-annular clamp component 202 corresponds to the corresponding perforation on the old pipeline, and ensuring that the sealing element 103 can be inserted into the perforation. Then, the semi-annular clamp component 101 and the semi-annular clamp component 202 are connected by connecting bolts, so that the semi-annular clamp component 101 and the semi-annular clamp component 202 form a complete ring and are tightly clamped onto the old pipeline. The gap between the sealing element 103 and the perforation can be tightly sealed by the plastic sealing body.

[0041] In an optional embodiment of the present invention, as shown in the figure, the plastic seal includes a plastic gasket, the outer circular surface of which is in close contact with the inner wall of a corresponding perforation on the pipe, and its inner circular surface is in close contact with the outer wall of the seal 103.

[0042] It should be noted that, as mentioned above, when a plastic gasket is used for the plastic seal, as the seal 103 is inserted into the perforation, the plastic gasket is gradually compressed and deformed, so that the gap between the seal 103 and the perforation is tightly sealed.

[0043] In an optional embodiment of the present invention, the plastic seal includes a plastic bladder, a cavity disposed inside the semi-annular clamp fitting 102, and a one-way valve disposed in the cavity. One end of the cavity is connected to the internal space of the plastic bladder, and the other end is connected to the outside. The one-way valve is used to restrict fluid to flow only from the outside to the plastic bladder.

[0044] It should be noted that, as mentioned above, when a plastic bladder is used as the plastic seal, fluid can be introduced into the plastic bladder from the outside, causing a change in the pressure inside the plastic bladder. This seals the gap between the seal 103 and the perforation. At the same time, the pressure inside the plastic bladder can be adjusted according to the pressure of the fluid inside the pipeline, thereby preventing the plastic bladder from deforming under high pressure and causing fluid leakage from the pipeline.

[0045] In an optional embodiment of the invention, such as Figure 2 and Figure 3 As shown, the protective mechanism 2 includes a fixed protective shell 201, an installation groove inside the fixed protective shell 201, a through hole 2 at the bottom of the installation groove, and a movable protective shell 202 that is detachably connected to the fixed protective shell 201. The installation groove is connected to the corresponding through hole on the pipe through the through hole 2, and the fixed protective shell 201 is fixedly connected to the semi-annular clamp pipe fitting 2 102.

[0046] It should be noted that when installing the monitoring module 4, the movable protective shell 202 can be removed from the fixed protective shell 201. After installation, the movable protective shell 202 can be reconnected to the fixed protective shell 201, which can provide stable protection for the monitoring module 4.

[0047] In an optional embodiment of the invention, such as Figures 3-6 As shown, the limiting assembly includes several evenly distributed fixing screws 301, a partition 302, several through holes 3 located in the middle of the partition 302, several limiting holes 1 located at the edge of the partition 302, and several nuts 3020 movably connected to the partition 302. The nuts 3020 are coaxially arranged with the limiting holes, the limiting holes 1 are respectively arranged corresponding to the fixing screws 301, the nuts 3020 are threadedly connected to the fixing screws 301, and the fixing screws 301 are all fixedly connected to the bottom of the mounting groove.

[0048] Telescopic isolation assembly 1 includes a partition 2 303, several through holes 4 located at the middle of partition 2 303, a telescopic threaded tube 1 304 fixedly connected to partition 2 303, a partition 3 305 fixedly connected to the other end of the telescopic threaded tube 1 304, several limiting plates 1 3050 fixedly connected to the outer circumference of partition 3 305, limiting holes 2 provided on limiting plates 1 3050, and screws movably connected to limiting plates 1 3050. The second nut 3051 and several through holes five are located in the middle of the third partition 305. The second nut 3051 is coaxially arranged with the second limiting hole. The second limiting hole is correspondingly arranged with the fixing screw 301. The second nut 3051 is threadedly connected with the fixing screw 301. Several through holes five and four are correspondingly arranged with several through holes three. The second partition 303 is movably connected with the first partition 302, and the second partition 303 and the first partition 302 are in close contact.

[0049] The telescopic isolation assembly 2 includes a partition plate 4 306, several through holes 6 located at the middle of the partition plate 4 306, a telescopic threaded tube 2 307 fixedly connected to the partition plate 4 306, a connecting ring 308 fixedly connected to the other end of the telescopic threaded tube 2 307, several limiting plates 2 3080 fixedly connected to the outer circular surface of the connecting ring 308, limiting holes 3 provided on the limiting plates 2 3080, and nuts 3 3081 movably connected to the limiting plates 2 3080. Nuts 3 3081 and limiting holes 3 are coaxially arranged, limiting holes 3 are correspondingly arranged with fixing screws 301, nuts 3081 and fixing screws 301 are threadedly connected, several through holes 6 are correspondingly arranged with several through holes 5, partition plate 4 306 and partition plate 3 305 are movably connected, and partition plate 4 306 and partition plate 3 305 are in close contact.

[0050] The monitoring module 4 includes a circuit integration module 401, a disturbance fluid 402 connected to the circuit integration module 401, and a detector. The detector is electrically connected to the circuit integration module 401, and the circuit integration module 401 is electrically connected to the terminal 6 via a wire 5. The disturbance fluid 402 and the detector are existing technologies and will not be described in detail here.

[0051] The circuit integration module 401 is detachably connected to the connecting ring 308. When the circuit integration module 401 and the connecting ring 308 are connected, the opening of the connecting ring 308 is sealed.

[0052] It should be noted that, as described above, the specific process for disassembling and subsequently installing monitoring module 4 is as follows: First, rotate nuts 3081 and 3051 to disengage them from the fixing screw 301, which in turn causes limit plates 2 3080 and 1 3050 to simultaneously disengage from the fixing screw 301. When limit plates 1 3050 and 2 3080 disengage from the fixing screw 301, partition 3 305 and connecting ring 308 can begin to rotate. When connecting ring 308 rotates, it can drive partition 4 306 to rotate synchronously through telescopic threaded tube 2 307. When partition 3 305 rotates, it can drive partition 2 303 to rotate synchronously through telescopic threaded tube 1 304. Rotation occurs, with both the second telescopic threaded tube 307 and the first telescopic threaded tube 304 in a stretchable state. At this time, the control circuit integrated module 401 moves upward, which in turn drives the connecting ring 308 to move upward synchronously, stretching the fourth partition 306 and the first telescopic threaded tube 304, so that the monitoring module 4 is completely detached from the pipe. At this time, the connecting ring 308 and the third partition 305 can be rotated synchronously, so that the several through holes four on the second partition 303 and the several through holes three on the fixed screw 301 are adjusted from a completely overlapping state to a completely non-overlapping state. At this time, both through holes three and four are in a stretchable state. In the sealed state, continue pulling the monitoring module 4 until the disturbing fluid 402 and the detector are completely inside the space between the partition 4 306, the telescopic threaded pipe 2 307, the connecting ring 308, and the circuit integration module 401. At this point, all the fluid in the space between the partition 4 306, the telescopic threaded pipe 2 307, the connecting ring 308, and the circuit integration module 401 flows from through holes 6 and 5 into the space formed between the partition 2 303, the telescopic threaded pipe 1 304, and the partition 3 305. At this point, fix the partition 3 305 and only rotate the connecting ring 308. This adjusts the several through holes six on partition four 306 and several through holes five on partition three 305 from a completely overlapping state to a completely non-overlapping state. Then, the circuit integrated module 401 can be detached from the connecting ring 308. Then, the connecting ring 308 and partition three 305 are rotated synchronously, so that through holes four and three are readjusted to the conductive state, while through holes six and five remain in the closed state. At this time, the connecting ring 308 can be compressed, so that most of the fluid in the space formed between partition two 303, telescopic threaded pipe one 304 and partition three 305 is forced back into the pipe.

[0053] When reinstalling monitoring module 4, adjust through holes 4 and 3 to the closed state, and through holes 6 and 5 to the open state. Then, re-stretch the telescopic threaded tube 2 307 and the telescopic threaded tube 1 304. After re-inserting the disturbing fluid 402 and the detector into through holes 6 and 5, reconnect the circuit integration module 401 to the connecting ring 308. Adjust through holes 4 and 3 to the open state, and then re-insert the disturbing fluid 402 and the detector into the pipe. Throughout the entire disassembly and installation process, it can be ensured that the fluid in the pipe will not leak out, thus ensuring the fluid flow in the pipe.

[0054] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
