Description

Technical Field

[0001] This utility model belongs to the technical field of electromagnetic vortex flowmeters, and more specifically, relates to a novel electromagnetic vortex flowmeter. Background Technology

[0002] The "new electromagnetic vortex flow meter" is a flow detection device that integrates electromagnetic sensing technology and vortex flow measurement principle. Its core is to capture the vortex signal generated by fluid oscillation through electromagnetic induction. Compared with traditional vortex flow meters, it has significant optimizations in signal stability, measurement accuracy and applicable scenarios.

[0003] In existing technologies, novel electromagnetic vortex flow meters typically have a generator inside. Its function is to generate stable vortices (Karman vortex street) when the fluid flows through it by obstructing the flow. The flow rate is then calculated by detecting the vortex frequency through an electromagnetic sensor. However, the generator is usually fixed directly inside the vortex flow meter pipe and cannot be replaced as needed (e.g., triangular prisms are used for liquids, and rectangular prisms are used for gases), resulting in poor applicability. Summary of the Invention

[0004] The purpose of this invention is to provide a novel electromagnetic vortex flow meter, which allows for the disassembly and replacement of the generator as needed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel electromagnetic vortex flowmeter is provided, comprising a pipe, a generator installed inside the pipe, a mounting base fixedly connected to the upper surface of the pipe, a fixed shaft fixedly connected to the upper surface of the generator, a mounting plate fixedly connected to the upper surface of the fixed shaft, the fixed shaft and the mounting plate slidably connected inside the mounting base, a sealing ring provided inside the pipe, the fixed shaft slidably connected inside the sealing ring, a connecting plate installed above the mounting plate, a connecting rod fixedly connected to the upper surface of the connecting plate, a flowmeter body installed on the outer wall of the connecting rod, a piezoelectric sensor installed inside the pipe, an insert block slidably connected inside the mounting base, the insert block slidably connected inside the mounting plate, a connecting block fixedly connected to the outer wall of the insert block, and a threaded rod movably connected inside the connecting block, the threaded rod being threadedly connected inside the mounting base.

[0012] This utility model includes a mounting base, a sealing ring, a generator, a fixed shaft, a mounting plate, a connecting block, an insert block, and a threaded rod. When different generators need to be replaced, a fixed shaft is fixed to the upper surface of each generator, and a mounting plate is fixed to the upper surface of the fixed shaft. The mounting plate is placed inside the mounting base, so that the fixed shaft is locked inside the pipe, and the sealing ring seals the fixed shaft. The generator is placed inside the pipe.

[0023] This invention provides a novel electromagnetic vortex flowmeter. The novel electromagnetic vortex flowmeter includes a pipe 1, with a generator 2 installed inside the pipe 1. A mounting base 101 is fixedly connected to the upper surface of the pipe 1. A fixed shaft 201 is fixedly connected to the upper surface of the generator 2. The diameter of the generator 2 is smaller than the diameter of the fixed shaft 201. Whether the generator 2 is triangular or rectangular, its diameter is smaller than the diameter of the fixed shaft 201. A mounting plate 202 is fixedly connected to the upper surface of the fixed shaft 201. The fixed shaft 201 facilitates sealing with the pipe 1, and the mounting plate 202 assists in the installation and fixing of the generator 2. The fixed shaft 201 and the mounting plate 202 are slidably connected inside the mounting base 101. A sealing ring 102 is provided inside the pipe 1. The connection is dynamically connected inside the sealing ring 102, which seals the connection between the fixed shaft 201 and the pipe 1. A connecting plate 3 is installed above the mounting plate 202. A connecting rod 301 is fixedly connected to the upper surface of the connecting plate 3. A flow meter body 302 is installed on the outer wall of the connecting rod 301. A piezoelectric sensor 5 is installed inside the pipe 1. An insert block 401 is slidably connected inside the mounting base 101. The insert block 401 is slidably connected inside the mounting plate 202. A connecting block 4 is fixedly connected to the outer wall of the insert block 401. A threaded rod 402 is movably connected inside the connecting block 4. The threaded rod 402 is limited to rotate inside the connecting block 4. The threaded rod 402 is threadedly connected inside the mounting base 101.

[0024] This utility model provides a novel electromagnetic vortex flowmeter, which, compared with the prior art, allows for the disassembly and replacement of the generator 2 as needed.

[0025] Please refer to another embodiment of this utility model as well. Figures 1 to 4The lower surface of the connecting plate 3 is in contact with the upper surface of the mounting base 101, and the lower surface of the connecting plate 3 is in contact with the upper surface of the mounting plate 202. The connecting plate 3 and the mounting plate 202 are fixedly connected by bolts. This bolted connection facilitates the installation of the connecting plate 3, the connecting rod 301, and the flowmeter body 302 after the mounting plate 202 is fixed in a limited position. The flowmeter body 302 is threaded to the upper end of the outer wall of the connecting rod 301. A connecting wire 501 is installed inside the flowmeter body 302. A piezoelectric sensor 5 is installed at the end of the connecting wire 501 away from the flowmeter body 302. The piezoelectric sensor 5 is electrically connected to the flowmeter body 302 through the connecting wire 501. The connecting wire 501 is bendable, and the piezoelectric sensor 5 is slidably connected inside the pipe 1. The detection of the piezoelectric sensor 5... The measuring end is placed inside the pipe 1. When the fluid flows from the left side to the right side of the pipe 1, it will form two regular asymmetric vortices, namely the Karman vortex street, on the right side after passing the generator 2. Then, the flow rate is detected by the measuring end of the piezoelectric sensor 5. The detection data is displayed through the flow meter body 302. The upper surface of the pipe 1 is fixedly connected to the mounting base 2 103. The piezoelectric sensor 5 is slidably connected inside the mounting base 2 103. The inside of the pipe 1 is provided with a sealing ring 2 104. The piezoelectric sensor 5 is slidably connected inside the sealing ring 2 104. The sealing ring 2 104 seals the connection between the piezoelectric sensor 5 and the pipe 1. The inside of the mounting base 2 103 is threadedly connected to a threaded rod 2 6. The threaded rod 2 6 is threadedly connected inside the piezoelectric sensor 5. The threaded rod 2 6 limits the installation of the piezoelectric sensor 5 inside the mounting base 2 103.

[0026] Working principle: When it is necessary to replace the generator 2 with a different shape, rotate the threaded rod 402 to disengage it from the interior of the mounting base 101. Simultaneously, the threaded rod 402 disengages from the mounting base 101, causing the connecting block 4 and the insert block 401 to move outwards. This allows the insert block 401 to slide out of the interior of the mounting plate 202. Then, separate the connecting wire 501 from the flowmeter body 302. Moving the flowmeter body 302 upwards causes the connecting rod 301 and the connecting plate 3 to move upwards. The upward movement of the connecting plate 3 causes the mounting plate 202, the fixed shaft 201, and the generator 2 to move upwards, allowing the generator 2 to leave the interior of the pipe 1. Then, remove the bolts connecting the connecting plate 3 and the mounting plate 202, allowing the replacement of the mounting plate 202, the fixed shaft 201, and the generator 2 with different shapes. After replacement, place the mounting plate 202, the fixed shaft 201, and the generator 2 vertically, and then lower the mounting plate 202 to allow the generator to move out of the interior of the pipe 1. The generator 2 penetrates into the interior of the mounting base 101 and the pipe 1. The fixed shaft 201 also slides into the interior of the mounting base 101 and is placed inside the sealing ring 102. The mounting plate 202 is limited and placed inside the mounting base 101. Then, the threaded rod 402 is rotated to make it threaded into the interior of the mounting base 101. The threaded rod 402 moves into the interior of the mounting base 101, driving the connecting block 4 and the insert block 401 to move, so that the insert block 401 slides into the interior of the mounting base 101 and is limited and locked inside the mounting plate 202. Then, the lower surface of the connecting plate 3 is attached to the upper surface of the mounting plate 202. Then, the connecting plate 3 and the mounting plate 202 are fixedly connected with bolts. Then, the connecting wire 501 is installed and connected inside the flow meter body 302, so that generators 2 of different shapes can be replaced, and the vortex flow meter can perform flow detection operations on liquids or gases.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
