Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vortex flow meter technology, specifically a vortex flow meter with an online replaceable probe sensor. Background Technology
[0002] Vortex flow meters are volumetric flow meters designed and manufactured based on the Karman vortex street principle to measure the volumetric flow rate, standard flow rate, or general flow rate of gases, steam, or liquids. They are primarily used for measuring the flow rate of fluids in industrial pipelines, including various media such as gases, liquids, and steam. Their characteristics include low pressure loss, a wide measuring range, and high accuracy. When measuring volumetric flow rate under operating conditions, they are virtually unaffected by parameters such as fluid density, pressure, temperature, and viscosity.
[0003] Existing vortex flowmeter sensors are typically connected to the mounting base using bolts. While this connection structure is simple and reliable, tightening the bolts requires specialized tools, is time-consuming, and is difficult to operate in high-altitude or confined spaces. Furthermore, frequent bolt removal can lead to thread wear, affecting the stability and sealing of the connection. Summary of the Invention
[0004] The purpose of this invention is to provide a vortex flow meter with an online replaceable probe sensor, which allows for quick sensor replacement without the need for tools.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vortex flow meter with an online replaceable probe sensor is provided, including a base. A mounting seat is provided on the top of the base. A rotating groove is formed inside the mounting seat. Multiple sliding grooves are formed inside the rotating groove. An annular groove is formed on the top of the mounting seat. A sensor is movably mounted in the middle of the mounting seat. A mounting plate is provided on the outer wall of the sensor. Multiple locking grooves are formed on the outer wall of the sensor. A turntable is provided inside the rotating groove. A linkage groove is formed inside the turntable. A handle is fixedly connected to the outer wall of the turntable. Locking blocks are provided inside the multiple sliding grooves. A linkage column is provided on the top of each locking block and is located inside the linkage groove. Multiple connecting blocks are provided on the outer wall of the mounting seat. A lead screw is movably connected to the outer wall of the rear connecting block. A moving block is threadedly connected to the outer wall of the lead screw. A roller is movably connected to the bottom of the moving block and is located inside the handle.
[0006] Optionally, a plurality of the locking slots are located at the lower end of the mounting plate, and both the locking slots and the locking blocks have triangular cross-sections.
[0007] Optionally, a limiting plate is fixedly connected between the two connecting blocks, and the limiting plate passes through the moving block.
[0008] Optionally, a first sealing ring is installed inside the annular groove, and a second sealing ring is provided at the contact point between the sensor and the mounting base, and the number of second sealing rings is two.
[0009] Optionally, the annular groove has multiple positioning holes inside, and the bottom of the mounting plate has multiple positioning posts, each of which is located inside a plurality of positioning holes.
[0010] Optionally, the mounting base is bolted to a connecting plate, a connecting rod is fixedly connected to the top of the connecting plate, a meter head is fixedly connected to the top of the connecting rod, the top of the sensor is located inside the connecting rod, and the sensor is linearly connected to the meter head.
[0011] Optionally, flanges are fixedly connected to both ends of the base, a third sealing ring is installed on the outer wall of the flange, and a generator is fixedly connected inside the base, the generator being triangular in shape.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This utility model comprises a base, mounting seat, sensor, mounting plate, turntable, throttle, locking block, linkage column, connecting block, lead screw, moving block, and roller. The lead screw drives the linear movement of the moving block. When the lead screw is rotated, the moving block, which is threaded to it, moves forward under the guidance of the limiting plate, driving the roller embedded in the groove of the turntable to move. Since the roller is located inside the turntable, the turntable rotates clockwise, and the turntable drives the turntable to rotate clockwise synchronously. The linkage groove inside the turntable drives the linkage column to move, thereby pushing the locking block to slide in the groove. When the triangular end of the locking block is embedded in the locking groove of the mounting plate, the sensor is clamped and fixed; otherwise, it is unlocked and can be easily removed. This design solves the problems of tool dependence and cumbersome operation in traditional bolt connections. Attached Figure Description

[0028] Reference Figure 1-8 This invention provides a vortex flow meter with an online replaceable probe sensor. The vortex flow meter includes a base 1, a mounting seat 2 on the top of the base 1, a rotating groove 3 inside the mounting seat 2, and multiple sliding grooves 4 inside the rotating groove 3. An annular groove 5 is formed on the top of the mounting seat 2. A sensor 6 is movably mounted in the middle of the mounting seat 2. A mounting plate 7 is provided on the outer wall of the sensor 6, and multiple locking grooves 8 are formed on the outer wall of the sensor 6. A turntable 9 is provided inside the rotating groove 3. A linkage groove 10 is provided. A handle 11 is fixedly connected to the outer wall of the turntable 9. A locking block 12 is provided inside the multiple sliding grooves 4. A linkage column 13 is provided on the top of the locking block 12. The linkage column 13 is located inside the linkage groove 10. A connecting block 14 is provided on the outer wall of the mounting base 2. There are multiple connecting blocks 14. A lead screw 15 is movably connected to the outer wall of the rear connecting block 14. A moving block 16 is threadedly connected to the outer wall of the lead screw 15. A roller 17 is movably connected to the bottom of the moving block 16. The roller 17 is located inside the handle 11.
[0029] In another embodiment of this utility model, please refer to Figure 3 Multiple locking slots 8 are located at the lower end of the mounting plate 7. The cross-section of the locking slots 8 and the locking block 12 is triangular. A limiting plate 18 is fixedly connected between the two connecting blocks 14, and the limiting plate 18 passes through the moving block 16.
[0030] When the lead screw 15 is rotated, the moving block 16, which is threaded with it, moves forward under the guidance of the limiting plate 18, driving the roller 17 embedded in the groove of the throttle 11 to move.

There are two second sealing rings 20. The first sealing ring 19 and the second sealing ring 20 form a double seal at the contact point between the annular groove 5 and the sensor 6 and the mounting base 2, respectively.
[0032] In another embodiment of this utility model, please refer to Figure 4 The annular groove 5 has multiple positioning holes 21 inside. The bottom of the mounting plate 7 has multiple positioning posts 22. The multiple positioning posts 22 are located inside the multiple positioning holes 21. During installation, the positioning posts 22 at the bottom of the mounting plate 7 cooperate with the positioning holes 21 in the annular groove 5 to ensure accurate positioning.
[0033] In another embodiment of this utility model, please refer to Figures 1 to 2 The mounting base 2 is connected to a connecting plate 23 by bolts. A connecting rod 24 is fixedly connected to the top of the connecting plate 23. A meter head 25 is fixedly connected to the top of the connecting rod 24. The top of the sensor 6 is located inside the connecting rod 24. The sensor 6 is linearly connected to the meter head 25.
[0034] In another embodiment of this utility model, please refer to Figure 4 Flanges 26 are fixedly connected to both ends of the base 1. A third sealing ring 27 is installed on the outer wall of the flange 26. The third sealing ring 27 on the flange 26 ensures the sealing of the pipe connection. A generator 28 is fixedly connected inside the base 1. The generator 28 is triangular in shape.
