[0019] The mounting ring 7 is equipped with a rotating component 4 for rotating the transducer 2 at an angle. The rotating assembly 4 includes a slide rail 41 detachably mounted on the mounting ring 7 by bolts. Two slide rails 41 are symmetrically arranged. A movable component is provided inside the slide rail 41. Several sets of movable components are linearly arranged. The movable component includes a first slider 42 slidably connected inside the slide rail 41. The first slider 42 has a first through hole 47. A first moving ring 44 is inserted into the first through hole 47. A second slider 48 is slidably connected inside the slide rail 41. A connecting rod 43 is detachably installed between the first slider 42 and the second slider 48. A second through hole 49 is provided inside the second slider 48. A second moving ring 410 is inserted into the second through hole 49. The first moving ring 44 and the second moving ring 410 are made of strip-shaped annular steel material. Their ends are connected by bolts. Both the first moving ring 44 and the second moving ring 410 have mounting holes 45. Several sets of mounting holes 45 are provided. A fixing rod 46 is detachably installed between the first moving ring 44 and the second moving ring 410 by bolts. The first slider 42 and the second slider 48 in the slide rail 41 of the rotating assembly 4 can slide within the slide rail 41, driving the first moving ring 44 and the second moving ring 410 to move synchronously, thereby adjusting the position and angle of the transducer 2.

[0020] Both the first moving ring 44 and the second moving ring 410 are provided with fixing parts 6. The fixing parts 6 include a first fixing block 61 that is detachably installed on the mounting hole 45 by bolts. A second screw 62 is threadedly connected to the first fixing block 61. A nut 63 is fixedly installed on the left end of the second screw 62. A second fixing block 64 is rotatably connected to the right end of the second screw 62.

A coupling pad 67 is placed between the transducer 2 and the water pipe 1. The transducer 2 is clamped and fixed by the fastener 6. The clamping force can be controlled by adjusting the second screw 62 and the third screw 68 to prevent the transducer 2 from loosening.

[0021] The mounting ring 7 is equipped with mounting parts 5, which are used to adapt to pipes of different diameters; Mounting component 5 includes a first screw 51 threadedly connected to mounting ring 7. A torsion bar 52 is fixedly mounted on the outer end of the first screw 51 for easy manual adjustment. A clamp 58 is rotatably connected to the inner end of the first screw 51. A third fixing block 53 is detachably mounted on the top of slide rail 41. Four third fixing blocks 53 are symmetrically arranged. A slide rod 54 is detachably mounted between two third fixing blocks 53. A movable seat 55 is slidably connected to the two slide rods 54. A support rod 56 is rotatably connected to the movable seat 55. A mounting plate 57 is hinged to the top of the support rod 56 for easy adjustment of position according to site requirements. The position of the clamp 58 is adjusted by rotating the first screw 51, so that the mounting ring 7 adapts to the outer diameter of the pipe. The movable seat 55 slides along the slide bar 54, and the support rod 56 drives the mounting plate 57 to adjust the angle, ensuring that the calculator 3 is in the appropriate position.

[0022] Working principle: In actual use, the position of the clamp 58 is adjusted by rotating the first screw 51 according to the diameter of the pipe to be tested, so that the mounting ring 7 adapts to the outer diameter of the pipe. The movable seat 55 slides along the slide rod 54, and the support rod 56 drives the mounting plate 57 to adjust the angle to ensure that the calculator 3 is in the right position. The take-up reel 8 takes up the excess cable to prevent tangling. Through the adjustment function of the mounting part 5, it can be adapted to pipes of different diameters, which improves the versatility and applicability of the device.

[0023] The first slider 42 and the second slider 48 in the slide rail 41 of the rotating assembly 4 can slide within the slide rail 41, driving the first moving ring 44 and the second moving ring 410 to move synchronously, thereby adjusting the position of the transducer 2. By rotating the first moving ring 44 and the second moving ring 410, the transducer 2 can rotate within a certain angle, thereby adjusting the angle of the transducer 2. Tightening the second screw 62 drives the second fixing block 64 to move towards the water pipe 1, so that the coupling pad 67 presses against the water pipe 1, thereby fixing the position of the transducer 2. The transducer 2 is clamped and fixed by the fixing member 6. Adjusting the second screw 62 and the third screw 68 can control the clamping force and prevent the transducer 2 from loosening. By setting the rotating assembly 4, the transducer 2 can rotate around the pipe, realizing multi-angle and multi-position ultrasonic transmission and reception, effectively improving the measurement accuracy, reducing the influence of cavities or incomplete pipes on fluid measurement, and solving the problem of inaccurate measurement caused by the inability to measure from multiple angles when using traditional multi-channel ultrasonic flow meters.
