Description

Technical Field

[0001] This utility model belongs to the technical field of flow meter fixing bracket devices, specifically an anti-vibration interference type flow meter fixing bracket device. Background Technology

[0002] An ultrasonic flow meter is a type of flow meter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the velocity of the sound wave in a stationary medium. It mainly consists of a transducer and a converter. Flow meters typically need to be installed on a fixed bracket.

[0003] When using existing flow meter mounting brackets, the flow of liquid inside the flow tube causes the flow tube to vibrate, resulting in a large error in the flow meter's detection results. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration-resistant flow meter mounting bracket device to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows: a vibration-resistant flow meter fixing bracket device, including a support frame, a screw at the top of the support frame, a threaded plate threaded to the outer wall of the screw, an active plate fixedly connected to the bottom of the threaded plate, upper clamping plates fixedly connected to both ends of the active plate, a limiting groove provided at the connection between the support frame and the upper clamping plates, a linkage plate movably connected to the outer wall of the active plate and screwed to the inner wall of the support frame, a driven plate movably connected to the bottom end of the linkage plate, lower clamping plates fixedly connected to both ends of the driven plate and slidably connected to the limiting groove, an isolation washer provided at the connection between the upper and lower clamping plates, a damping pad abutting one end of the lower clamping plate and a damping pad abutting one end of the upper clamping plate, a flow tube penetrating through the inner wall of the isolation washer, an installation frame fixedly connected to the outer wall of the flow tube, ultrasonic probes penetrating through both sides of the outer wall of the installation frame, and a dial fixedly connected to the top of the installation frame.

[0006] Based on the above structure, the screw drives the active plate to slide along the groove of the limiting slide through the threaded plate. The sliding of the active plate drives the upper clamping plate to slide synchronously. At the same time, the sliding of the active plate drives the driven plate to slide along the groove of the limiting slide through the linkage plate. This causes the driven plate to drive the lower clamping plate and the upper clamping plate to slide synchronously relative to each other, so that the isolation gasket is tightly fitted to the outer wall of the flow tube, thus achieving protective support for the flow tube.

[0007] Preferably, the active plate and the driven plate are centrally symmetrical about the rotation center of the linkage plate. In this embodiment, it is convenient for the active plate to slide through the linkage plate and drive the driven plate to slide along the groove of the limiting slide, so as to realize the relative sliding operation of the active plate and the driven plate.

[0008] Preferably, the upper clamping plate forms a clamping structure with the lower clamping plate through the active plate and the driven plate. In this embodiment, the active plate slides to drive the upper clamping plate to slide synchronously, and at the same time, the driven plate slides to drive the lower clamping plate to slide synchronously relative to the upper clamping plate, so that the isolation gasket is tightly attached to the outer wall of the flow tube.

[0009] Preferably, the upper and lower clamping plates are semi-circular in shape. In this embodiment, by setting the upper and lower clamping plates to be semi-circular, it is beneficial for the lower clamping plate to slide relative to the upper clamping plate synchronously, thereby making the isolation gasket fit tightly against the outer wall of the flow tube, thus achieving protective support for the flow tube.

[0010] Preferably, the cross-section of the isolation gasket is concave. In this embodiment, by setting the isolation gasket with a concave cross-section, the displacement of the isolation gasket is avoided.

[0011] Preferably, the damping pad and the flow pipe are located at the same height. In this embodiment, when the liquid flows, it will cause the flow pipe to vibrate. The kinetic energy generated by the vibration of the flow pipe is transmitted to the damping pad and absorbed, thereby reducing the vibration of the flow pipe.

[0012] Preferably, two sets of ultrasonic probes are provided, and the angle between the central axis of the ultrasonic probe and the central axis of the flow tube is acute. In this embodiment, when the ultrasonic probe is working, the sound waves transmitted downstream are accelerated by the fluid, while the sound waves transmitted upstream are delayed. The time difference between the two is proportional to the flow velocity, thereby measuring the liquid flow velocity in the flow tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets up a lower clamping plate and an upper clamping plate. The screw drives the active plate to slide along the groove of the limiting slide through the threaded plate. The sliding of the active plate drives the upper clamping plate to slide synchronously. At the same time, the sliding of the active plate drives the driven plate to slide along the groove of the limiting slide through the linkage plate. This makes the sliding of the driven plate drive the lower clamping plate and the upper clamping plate to slide synchronously relative to each other. This makes the isolation gasket fit tightly against the outer wall of the flow tube, thus achieving protective support for the flow tube.

[0015] 2. By setting up a damping pad, when the ultrasonic probe is working, the sound waves transmitted downstream are accelerated by the fluid, while the sound waves transmitted upstream are delayed. The time difference between the two is proportional to the flow velocity, so the flow velocity of the liquid in the flow tube can be measured. Then, when the liquid flows, it will cause the flow tube to vibrate. The kinetic energy generated by the vibration of the flow tube is transmitted to the damping pad and absorbed, thereby reducing the vibration of the flow tube. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0022] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0023] This utility model discloses a vibration-resistant flow meter fixing bracket device, including a support frame 1. A screw 2 is provided at the top of the support frame 1. A threaded plate 3 is threadedly connected to the outer wall of the screw 2. An active plate 4 is fixedly connected to the bottom end of the threaded plate 3. Upper clamping plates 5 are fixedly connected to both ends of the active plate 4. A limit groove 6 is provided at the connection between the support frame 1 and the upper clamping plate 5. A linkage plate 7 is movably connected to the outer wall of the active plate 4 and screwed to the inner wall of the support frame 1. The bottom end of the linkage plate 7 is movably connected to... There is a driven plate 8, and both ends of the driven plate 8 are fixedly connected to a lower clamping plate 9 that slides within the groove of the limiting slide 6. An isolation gasket 10 is provided at the connection between the upper clamping plate 5 and the lower clamping plate 9. A damping pad 11 is attached to one end of the lower clamping plate 9 and to one end of the upper clamping plate 5. A flow tube 12 passes through the inner wall of the isolation gasket 10. An installation frame 13 is fixedly connected to the outer wall of the flow tube 12. Ultrasonic probes 14 pass through both sides of the outer wall of the installation frame 13. A dial 15 is fixedly connected to the top of the installation frame 13.

[0024] Based on the above structure, the screw 2 drives the active plate 4 to slide along the groove of the limiting slide groove 6 through the threaded plate 3. The sliding of the active plate 4 drives the upper clamping plate 5 to slide synchronously. At the same time, the sliding of the active plate 4 drives the driven plate 8 to slide along the groove of the limiting slide groove 6 through the linkage plate 7. This causes the driven plate 8 to slide synchronously with the lower clamping plate 9 and the upper clamping plate 5, thereby making the isolation gasket 10 tightly fit with the outer wall of the flow tube 12, achieving protective support for the flow tube 12.

[0025] In one embodiment, the active plate 4 and the driven plate 8 are centrally symmetrical about the rotation center of the linkage plate 7, which facilitates the sliding of the active plate 4. The driven plate 8 is driven by the linkage plate 7 to slide along the groove of the limiting slide groove 6, thereby realizing the relative sliding of the active plate 4 and the driven plate 8.

[0026] In one embodiment, the upper clamping plate 5 forms a clamping structure with the lower clamping plate 9 through the active plate 4 and the driven plate 8.

[0027] The sliding of the active plate 4 causes the upper clamping plate 5 to slide synchronously. At the same time, the sliding of the driven plate 8 causes the lower clamping plate 9 to slide synchronously relative to the upper clamping plate 5, thereby making the isolation gasket 10 tightly fit with the outer wall of the flow tube 12.

[0028] In one embodiment, the upper clamping plate 5 and the lower clamping plate 9 are semi-circular in shape.

[0029] By setting the upper clamping plate 5 and the lower clamping plate 9 in a semi-circular arc shape, it is helpful for the lower clamping plate 9 to slide synchronously relative to the upper clamping plate 5, so that the isolation gasket 10 fits tightly against the outer wall of the flow tube 12, thereby achieving protective support for the flow tube 12.

[0030] In one embodiment, the cross-section of the isolation gasket 10 is concave.

[0031] By setting the isolation washer 10 with a concave cross-section, the displacement of the isolation washer 10 is prevented.

[0032] In one embodiment, the damping pad 11 is at the same height as the flow tube 12.

[0033] When the liquid flows, it causes the flow tube 12 to vibrate. The kinetic energy generated by the vibration of the flow tube 12 is transmitted to the damping pad 11 and absorbed, thereby reducing the vibration of the flow tube 12.

[0034] In one embodiment, two sets of ultrasonic probes 14 are provided, and the angle between the central axis of the ultrasonic probes 14 and the central axis of the flow tube 12 is acute.

[0035] When the ultrasonic probe 14 is working, the sound waves transmitted downstream are accelerated by the fluid, while the sound waves transmitted upstream are delayed. The time difference between the two is proportional to the flow velocity, thus the flow velocity of the liquid in the flow tube 12 can be measured.

[0036] When using this utility model, firstly, the screw 2 is rotated. The screw 2 drives the active plate 4 to slide along the groove of the limiting slide groove 6 through the threaded plate 3. The sliding of the active plate 4 drives the upper clamping plate 5 to slide synchronously. At the same time, the sliding of the active plate 4 drives the driven plate 8 to slide along the groove of the limiting slide groove 6 through the linkage plate 7. This causes the driven plate 8 to slide synchronously with the lower clamping plate 9 and the upper clamping plate 5, thereby making the isolation washer 10 tightly fit with the outer wall of the flow tube 12, achieving protective support for the flow tube 12.

[0037] When the ultrasonic probe 14 is working, the sound waves transmitted downstream are accelerated by the fluid, while the sound waves transmitted upstream are delayed. The time difference between the two is proportional to the flow velocity, thus the flow velocity of the liquid in the flow tube 12 can be measured.

[0038] When the liquid flows, it causes the flow tube 12 to vibrate. The kinetic energy generated by the vibration of the flow tube 12 is transmitted to the damping pad 11 and absorbed, thereby reducing the vibration of the flow tube 12.
