[0025] like Figures 1 to 6As shown, a time-difference ultrasonic flow meter measuring device includes a U-shaped base 2 and an ultrasonic flow meter body 23. A double-ended lead screw 4 is rotatably connected inside the U-shaped base 2. Two lead screw sleeves 5 adapted to the double-ended lead screw 4 are provided on the double-ended lead screw 4. A horizontal plate 6 is fixedly connected to the lower side of each of the two lead screw sleeves 5. A sliding rod 7 is fixedly connected inside each of the two horizontal plates 6. A first arc-shaped clamping plate 8 and a second arc-shaped clamping plate 9 are slidably connected to the outer surface of each of the two sliding rods 7.

[0026] Springs 10 are fixedly connected between the two first arc-shaped clamps 8 and the second arc-shaped clamps 9. Through the setting of the first arc-shaped clamps 8 and the second arc-shaped clamps 9, the elastic first arc-shaped clamps 8 and the second arc-shaped clamps 9 can be moved and adjusted on the slide rod 7 to clamp the pipe, which is conducive to the convenient installation and removal of the time difference ultrasonic flow meter measuring device. Rubber pads 11 are fixedly connected to one side of the two first arc-shaped clamps 8 and the second arc-shaped clamps 9. The rubber pads 11 can increase the friction between the first arc-shaped clamps 8 and the second arc-shaped clamps 9 and the pipe, so as to stably position the flow measuring device. Two symmetrically arranged arc-shaped blocks 3 are fixedly connected to the lower side of the U-shaped seat 2. L-shaped rotating plates 12 are rotatably connected to one side of the two first arc-shaped clamps 8. Grooves 13 are opened on one side of the two second arc-shaped clamps 9.

[0027] Guide rods 14 are slidably connected to one side of each of the two L-shaped rotary plates 12. One side of the guide rods 14 passes through the L-shaped rotary plates 12 and extends to the other side of the L-shaped rotary plates 12. A round seat 15 that fits the groove 13 is fixedly connected to one side of each of the two guide rods 14. One side of the round seat 15 is snapped into the inside of the groove 13. A spring 16 is fixedly connected between each of the two round seats 15 and the L-shaped rotary plates 12. A round plate 17 is fixedly connected to the other side of each of the two guide rods 14. Two side plates 24 are fixedly connected to both ends of the U-shaped seat 2. A support plate 25 that fits the pipe is fixedly connected to one side of each of the four side plates 24.

[0028] The upper side of the U-shaped base 2 is fixedly connected to the main body 21 of the flow measuring device. One side of the main body 21 of the flow measuring device is fixedly connected to a fixing box 22 that is adapted to the main body 23 of the ultrasonic flow meter. The lower side of the main body 23 of the ultrasonic flow meter is snapped into the inside of the fixing box 22. The other side of the main body 21 of the flow measuring device is snapped into an L-shaped plug 28. One side of the L-shaped plug 28 passes through the main body 21 of the flow measuring device and extends to one side of the main body 21 of the flow measuring device. Through the setting of the fixing box 22 and the L-shaped plug 28, the main body 23 of the ultrasonic flow meter can be snapped into and fixed by the fixing box 22. Then the L-shaped plug 28 can limit and fix the main body 23 of the ultrasonic flow meter, which has good stability.

[0029] A wire 26 is fixedly connected to one side of the ultrasonic flow meter body 23, and an ultrasonic probe 27 is fixedly connected to one side of the wire 26. The ultrasonic probe 27 measures the time difference of fluid propagation in the pipe in the forward and reverse directions by emitting and receiving ultrasonic signals, and then calculates the flow velocity and flow rate. A protective cover 29 is fixedly connected to the outer surface of the ultrasonic probe 27, and a slide plate 31 is arrayed on the outer surface of the protective cover 29. A slide plate 31 is slidably engaged with one side of the slide plate 31, and a magnet 32 ​​is fixedly connected to one side of the slide plate 31. A second bolt 33 that contacts the slide plate 31 is threadedly connected to one side of the fixing block 30.

[0030] Two mounting blocks 34 are fixedly connected to one side of the U-shaped base 2. T-slots 35 are opened on one side of each mounting block 34. A locking block 36 is locked inside each of the two T-slots 35. A baffle 37 for attaching to the wire 26 is fixedly connected to one side of each locking block 36.

[0031] The lower sides of the two L-shaped rotating plates 12 are threaded with first bolts 18. The U-shaped seat 2 is fixedly connected with a limit rod 19. The inside of the screw sleeve 5 is slidably placed on the outer surface of the limit rod 19. The limit rod 19 can be used to limit and guide the movement trajectory of the two screw sleeves 5, ensuring that the first arc-shaped clamp 8 and the second arc-shaped clamp 9 can move and adjust smoothly to clamp onto pipes of different lengths. One side of the double-ended screw 4 passes through the U-shaped seat 2 and extends to one side of the U-shaped seat 2. A handwheel 20 is fixedly connected to one side of the double-ended screw 4.

[0032] The working principle of the time-difference ultrasonic flowmeter flow measurement device provided by this utility model is as follows:

[0033] By turning the handwheel 20, the double-ended lead screw 4 will rotate, allowing the two lead screw sleeves 5 on the double-ended lead screw 4 to move towards or relative to each other. This enables the two sets of first arc-shaped clamping plates 8 and second arc-shaped clamping plates 9 to flexibly adjust their spacing to accommodate pipes of different lengths, thus fixing the time-difference ultrasonic flow meter measuring device. Then, pulling the elastic first arc-shaped clamping plates 8 and second arc-shaped clamping plates 9 allows them to fit and clamp onto the outer surface of the pipe, initially fixing the time-difference ultrasonic flow meter measuring device. Next, the elastic... The two round seats 15 can be retracted, and the L-shaped rotating plate 12 is rotated to reach the groove 13. Then, the elastic round seats 15 are released and locked into the inside of the groove 13 to securely position the first arc-shaped clamping plate 8 and the second arc-shaped clamping plate 9. At the same time, the first bolt 18 is tightened to press the positioning guide rod 14 to ensure the stability of the arc-shaped clamping plate when it is fixed. In this way, the snap-fit ​​quick-release mechanism can flexibly and conveniently install and remove the entire device, allowing the device to be adapted to clamp onto pipes of different sizes, saving time and effort and improving the working efficiency of the time difference ultrasonic flow meter flow measurement device.

[0034] By sequentially moving the slide plate 31 at the fixed block 30, the slide plate 31 drives the magnet 32 ​​to maintain the same horizontal plane as the ultrasonic probe 27. Then, the second bolt 33 is tightened to fix the magnet 32. Subsequently, the array of magnets 32 can drive the ultrasonic probe 27 to be freely attracted to the pipe, allowing the ultrasonic probe 27 to adhere to the outer wall of the pipe so that the ultrasonic flow can be detected. Next, the locking block 36 is engaged into the T-slots 35 of the two mounting blocks 34 to fix the baffle 37. At this time, the baffle 37 can be used to support and position the wire 26 of the ultrasonic probe 27, reducing the slippage caused by the weight of the ultrasonic probe 27 and ensuring the stability of the ultrasonic probe 27 when it is fixed. At the same time, the arc block 3 and the support plate 25 can support and position the U-shaped seat 2 so that the main body of the flow measuring device 21 can be fixed on the pipe.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
