[0002] Flow measurement instruments are industrial automation instruments used to measure the flow rate of fluids such as liquids, gases, or steam in pipes or open channels; they are also called flow meters. Electromagnetic flow meters are induction-type instruments manufactured based on Faraday's law of electromagnetic induction, used to measure the volumetric flow rate of conductive media in pipes. Electromagnetic flow meters typically include a magnetic circuit system, measuring conduit, electrodes, housing, lining, and converter.

[0003] The reference patent (publication number: CN209927198U; publication date: 2020-01-10) relates to a detachable electromagnetic flowmeter, which is applied in the field of flow measurement instruments. The key technical points of the solution are: it includes a flowmeter body and a measuring conduit. The measuring conduit is located on the flowmeter body. Both ends of the measuring conduit are connected to connecting pipes with valves. Connecting sleeves adapted to the connecting pipes are fitted on both ends of the measuring conduit. The connecting sleeves are rotatably connected to the measuring conduit. One end of the connecting sleeve extends out of the measuring conduit, and the inner wall of the end of the connecting sleeve extending out of the measuring conduit is threadedly connected to the connecting pipe.

[0004] Traditional electromagnetic flow meters inevitably malfunction during use, requiring removal from the pipeline for maintenance. However, electromagnetic flow meters are typically fixed to the pipeline via flanges, necessitating the tightening of multiple nuts during disassembly. This process is often complex and time-consuming, and installation can easily lead to misalignment errors. Furthermore, impurities in the fluid entering the electromagnetic flow meter can interfere with the transmission of measurement signals, reduce measurement accuracy, and potentially damage the internal structure. Therefore, this invention provides a detachable electromagnetic flow meter. Utility Model Content

[0014] Beneficial effects

[0015] This invention provides a detachable electromagnetic flowmeter. Compared with the prior art, it has the following advantages:

[0016] Firstly, the locking bracket and locking rod of this utility model slide out along the locking holes on the first and second connecting plates. Then, the locking bracket rotates on the mounting plate via the connecting shaft, allowing the delivery pipe to be disassembled from the electromagnetic flowmeter body. During installation, the delivery pipe is attached to the first connecting plate via the second connecting plate. The locking bracket is rotated inward via the connecting shaft, causing the two sets of mounting plates to approach each other. This causes the locking rod on the locking bracket to engage with the locking holes on the first and second connecting plates, allowing the delivery pipe to be installed on the electromagnetic flowmeter body. This convenient disassembly and installation design allows operators to quickly complete the relevant work when maintenance or replacement of the electromagnetic flowmeter is required, thereby shortening downtime and improving production efficiency without the need for complicated tools or operating procedures.

[0017] Secondly, the electromagnetic flowmeter body of this utility model is tightly fitted to the second connecting plate via a rubber ring and a sealing groove, filling the tiny gaps between the connection interfaces to form a tight seal and prevent fluid leakage. Simultaneously, the positioning groove on the inner wall of the sealing groove engages with the positioning rod on the rubber ring, ensuring precise alignment between the electromagnetic flowmeter and the delivery pipe. This avoids installation deviations and improves installation accuracy. Furthermore, a filter screen bracket, bolted to a limiting frame fixed to the inner wall of the delivery pipe near the electromagnetic flowmeter body, filters impurities in the fluid, preventing them from entering the electromagnetic flowmeter body and affecting measurement accuracy. This effectively blocks large particles in the fluid, protecting the internal structure of the electromagnetic flowmeter from damage and extending its service life. Attached Figure Description

[0025] Please see Figure 1-4 This utility model provides a technical solution: a detachable electromagnetic flowmeter, including an electromagnetic flowmeter body 1, on which an installation mechanism for the electromagnetic flowmeter is provided, the installation mechanism including:

[0026] The locking assembly includes six sets of sliding grooves 2 opened on the outer wall of the electromagnetic flowmeter body 1.

The two side walls of the electromagnetic flowmeter body 1 are fixedly connected to the first connecting plate 3. The interior of the first connecting plate 3 is provided with six sets of first locking holes 301. The right side wall of the first connecting plate 3 is provided with a threaded rod 703 connected by a drive assembly.

[0027] The positioning assembly includes a rubber ring 302 fixedly connected to the left side wall of the first connecting plate 3, a positioning rod 303 fixedly connected to the outer wall of the rubber ring 302, a second connecting plate 4 attached to the left side wall of the first connecting plate 3, a sealing groove 402 opened on the inner wall of the second connecting plate 4, a conveying pipe 6 fixedly connected to the left end of the second connecting plate 4, and a filter assembly for blocking impurities provided on the inner wall of the conveying pipe 6.

[0028] In a preferred embodiment, a positioning groove 403 is provided on the inner wall of the sealing groove 402. The first connecting plate 3 is engaged with the sealing groove 402 via a rubber ring 302. The positioning rod 303 is correspondingly connected to the positioning groove 403. The electromagnetic flowmeter body 1 is tightly fitted to the second connecting plate 4 via the rubber ring 302 and the sealing groove 402, filling the tiny gaps between the connection interfaces to form a tight seal and prevent fluid leakage. At the same time, the positioning groove 403 on the inner wall of the sealing groove 402 is engaged with the positioning rod 303 on the rubber ring 302, ensuring precise alignment between the electromagnetic flowmeter and the delivery pipe 6, avoiding installation deviations and improving installation accuracy.

[0029] In a preferred embodiment, the interior of the second connecting plate 4 is provided with six sets of second locking holes 401, which correspond to and fit with the first locking holes 301. The first locking holes 301 and the second locking holes 401 are the same size as the locking rod 204 and can be inserted.

[0030] In a preferred embodiment, the inner ring wall of the mounting plate 201 is provided with protrusions, and the protrusions are located inside the six sets of sliding grooves 2. The mounting plate 201 can slide along the sliding grooves 2 on the outer wall of the electromagnetic flowmeter body 1 via the protrusions.

[0031] In a preferred embodiment, the drive assembly includes a mounting bracket 7 fixedly connected to the front end of the electromagnetic flowmeter body 1. A handwheel rod 701 is rotatably connected inside the front end of the mounting bracket 7. A drive gear 702 is fixedly connected to the inner end of the handwheel rod 701. A transmission gear 704 is fixedly connected to the end of a threaded rod 703 near the drive gear 702. The drive gear 702 and the transmission gear 704 are meshed. The threaded rod 703 is rotatably connected to the inner wall of the mounting plate 201. Rotating the handwheel rod 701 drives the drive gear 702 to rotate. Then, the threaded rod 703 rotates on the side wall of the first connecting plate 3 under the action of the handwheel rod 701 through the transmission gear 704 and the drive gear 702. The mounting plate 201 is then threadedly connected to the threaded rod 703, allowing the mounting plate 201 to slide on the outer wall of the electromagnetic flowmeter body 1 through the threaded rod 703 and the sliding groove 2. When the mounting plate 201 moves towards the electromagnetic flowmeter body 1... When the two sides of the body 1 slide, the locking bracket 203 and the locking rod 204 slide out along the locking holes on the first connecting plate 3 and the second connecting plate 4. Then, the locking bracket 203 rotates on the mounting plate 201 through the connecting shaft 202, so that the conveying pipe 6 can be disassembled from the electromagnetic flowmeter body 1. During installation, the conveying pipe 6 is attached to the first connecting plate 3 through the second connecting plate 4. The locking bracket 203 is rotated inward through the connecting shaft 202, so that the two sets of mounting plates 201 are close to each other, which drives the locking rod 204 on the locking bracket 203 to engage with the locking holes on the first connecting plate 3 and the second connecting plate 4. The conveying pipe 6 can then be installed with the electromagnetic flowmeter body 1. The convenient disassembly and installation design allows operators to quickly complete the relevant work when the electromagnetic flowmeter needs maintenance or replacement, thereby shortening downtime and improving production efficiency without the need for complicated tools or operating procedures.

[0032] Example 2, the technical solution that differs from Example 1 includes:

[0033] In a preferred embodiment, the filter assembly includes a limiting frame 5 fixedly connected to the inner wall of the delivery pipe 6, and a filter screen bracket 501 attached to the outer wall of the limiting frame 5. A bolt 502 is provided inside the outer ring of the filter screen bracket 501. The filter screen bracket 501, installed by bolt 502, is attached to the limiting frame 5 fixedly connected to the inner wall of the delivery pipe 6 near the electromagnetic flowmeter body 1. This filter screen bracket 501 is used to filter impurities in the fluid, preventing impurities from entering the electromagnetic flowmeter body 1 and affecting measurement accuracy. It effectively blocks large particles in the fluid, protects the internal structure of the electromagnetic flowmeter from damage, and extends its service life. Specifically, the detachable design makes the filter screen bracket 501 easy to disassemble and clean. When the filter screen is clogged or needs to be replaced, maintenance can be easily performed to maintain smooth fluid flow and measurement accuracy.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, the electromagnetic flowmeter body 1 is tightly fitted to the second connecting plate 4 through the rubber ring 302 and the sealing groove 402. At the same time, the positioning groove 403 opened on the inner wall of the sealing groove 402 is positioned and engaged with the positioning rod 303 on the rubber ring 302, ensuring the precise alignment between the electromagnetic flowmeter and the delivery pipe 6.

[0036] Then, by rotating the handwheel lever 701, the drive gear 702 is driven to rotate. The threaded rod 703 rotates on the side wall of the first connecting plate 3 under the action of the handwheel lever 701 via the transmission gear 704 and the drive gear 702. The mounting plate 201 is then threadedly connected to the threaded rod 703, allowing the mounting plate 201 to slide on the outer wall of the electromagnetic flowmeter body 1 via the threaded rod 703 and the sliding groove 2. When the mounting plate 201 slides towards both sides of the electromagnetic flowmeter body 1, the locking bracket 203 and the locking rod 204 slide out along the locking holes on the first connecting plate 3 and the second connecting plate 4. Then, the locking bracket 203 is connected to the connecting shaft 202... By rotating the mounting plate 201, the delivery pipe 6 and the electromagnetic flowmeter body 1 can be disassembled. During installation, the delivery pipe 6 is attached to the first connecting plate 3 via the second connecting plate 4. The locking bracket 203 is rotated inward via the connecting shaft 202, so that the two sets of mounting plates 201 come closer to each other. This causes the locking rod 204 on the locking bracket 203 to engage with the locking holes on the first connecting plate 3 and the second connecting plate 4, thus allowing the delivery pipe 6 and the electromagnetic flowmeter body 1 to be installed. The convenient disassembly and installation design allows operators to quickly complete the relevant work when the electromagnetic flowmeter needs maintenance or replacement, thereby shortening downtime.
