[0002] The transducer of an ultrasonic flow meter is the core component of an ultrasonic flow measurement system, primarily used for transmitting and receiving ultrasonic signals. Its working principle is based on the time-of-flight method, the Doppler effect, or related acoustic principles. It calculates the fluid velocity and flow rate by measuring the time difference or frequency change of ultrasonic waves propagating upstream and downstream in the fluid. Transducers are typically made of piezoelectric ceramic materials, enabling the conversion between electrical and acoustic signals. They offer advantages such as non-contact measurement, high accuracy, and a wide range of applicable media, making them widely used for flow monitoring in industrial, municipal, and energy sectors.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Reference Figure 1 and Figure 2 An embodiment of this utility model provides an ultrasonic flow meter transducer, including a pipe 1, a base 2 fixedly connected to the outer wall of the pipe 1, a fixing block 3 fixedly connected to the upper surface of the base 2, a motor 4 fixedly connected to the upper surface of the fixing block 3, the output end of the motor 4 rotatably connected to the inside of the fixing block 3 and fixedly connected to a gear 5, the tooth end of the gear 5 meshing with a rack 6, a clamp 8 fixedly connected to the outer wall of the rack 6, a transducer body 10 connected to the outer wall of the clamp 8, a rack 7 meshing with the tooth end of the gear 5, a clamp 9 fixedly connected to the outer wall of the rack 7, and the outer wall of the clamp 9 connected to the outer wall of the transducer body 10, and a limit component is provided on the upper surface of the base 2.

[0020] Specifically, the fixing block 3 fixes the motor 4, ensuring the stability of the motor 4 during operation. Through the fixed connection between the output end of the motor 4 and the gear 5, starting the motor 4 can drive the gear 5 to rotate. Through the meshing connection between the gear 5, rack 1 6 and rack 2 7, the rotational motion of the gear 5 can be converted into the opposite movement of rack 1 6 and rack 2 7. The opposite movement of rack 1 6 and rack 2 7 drives the clamp 1 8 and clamp 2 9 to move, thereby installing and fixing the transducer body 10.

[0021] Reference Figure 2 The limiting component includes a slide rail 11, the lower surface of which is fixedly connected to the upper surface of the base 2, the inside of a rack 6 is slidably connected to the outer wall of the slide rail 11, and a slide rail 2 12 is fixedly connected to the upper surface of the base 2, the inside of a rack 2 7 is slidably connected to the outer wall of the slide rail 2 12.

[0022] Specifically, the base 2 serves to fix the slide rail 11 and slide rail 2 12. The slide rail 11 and slide rail 2 12 respectively limit the movement of rack 6 and rack 7, ensuring that rack 6 and rack 7 move in a straight line.

[0023] Reference Figure 3 and Figure 4 The transducer body 10 has a through groove 20 on its outer wall and a semi-groove 21 on its interior. A side plate 22 is rotatably connected to the inner wall of the transducer body 10, and a connecting block 13 is slidably connected to the interior of the side plate 22. A locking block 14 is fixedly connected to the outer wall of the connecting block 13, and a sleeve 15 is fixedly connected to the outer wall of the locking block 14. The outer wall of the locking block 14 is slidably connected to the inner walls of the through groove 20 and the semi-groove 21. A round rod 16 is slidably connected to the interior of the sleeve 15, and a locking block 27 is fixedly connected to the bottom end of the round rod 16. One end of a spring 19 is fixedly connected to the outer wall of the locking block 14, and the other end of the spring 19 is fixedly connected to the outer wall of the locking block 27. A connecting block 28 is fixedly connected to the outer wall of the locking block 27, and the outer wall of the connecting block 28 is slidably connected to the interior of the side plate 22. The outer wall of the locking block 27 is slidably connected to the inner walls of the through groove 20 and the semi-groove 21.

[0024] Specifically, connecting block 13 and connecting block 2 18 provide the operator with a point of force to press. Through the fixed connection of connecting block 13, locking block 14 and sleeve 15, pressing connecting block 13 can drive locking block 14 to move downward. Through the fixed connection between round rod 16, locking block 2 17 and connecting block 2 18, pressing connecting block 2 18 can drive locking block 2 17 to move upward. When locking block 14 and locking block 2 17 move from the half groove 21 into the through groove 20, the side plate 22 can be unlocked and rotated away from the transducer body 10, thereby enabling the internal inspection and maintenance of the transducer body 10. The two ends of the spring 19 are connected to locking block 14 and locking block 2 17 respectively. The spring 19 stores or releases energy through elastic deformation to realize the reset function of locking block 14 and locking block 2 17. When locking block 14 and locking block 2 17 return to the half groove 21, the side plate 22 can be locked, thereby closing the transducer body 10.

[0025] Example 2: Reference Figure 5 In this embodiment, another structure is provided in the above embodiment: the transducer body 10 is internally threaded with bolts 23, and the outer wall of the side plate 22 is provided with threaded holes 24, and the outer wall of the bolts 23 is threadedly connected to the inner wall of the threaded holes 24.

[0026] Specifically, the threaded connection between the transducer body 10 and the bolt 23 allows the bolt 23 to be rotated and moved into the threaded hole 24, thereby achieving the installation and fixation of the side plate 22.

[0027] Working principle: The starting motor 4 drives the gear 5 to rotate. The rotation of gear 5 drives rack 6 and rack 7 to move towards each other. The movement of rack 6 and rack 7 drives clamp 8 and clamp 9 to move. The movement of clamp 8 and clamp 9 towards each other clamps the transducer body 10, achieving the effect of quick installation and fixation of the transducer body 10. This helps to reduce the reliance on professional technicians and effectively avoids errors caused by uneven tightening force.

[0028] When maintenance is required inside the transducer body 10, press connecting block 13 and connecting block 28 to move them inward. The movement of connecting block 13 and connecting block 28 causes locking block 14 and locking block 27 to move inward and compress spring 19. Locking block 14 and locking block 27 move from half-groove 21 into through groove 20, rotating side plate 22 away from inside the transducer body 10. When maintenance is complete, rotate side plate 22 back into the transducer body 10, release connecting block 13 and connecting block 28. Under the action of spring 19, locking block 14 and locking block 27 move outward back into half-groove 21, achieving the effect of quickly opening and closing side plate 22, which helps to improve the convenience of maintenance inside the transducer body 10.

[0029] In practical use, this ultrasonic flow meter transducer can not only achieve the effect of quickly installing and fixing the transducer body 10, but also achieve the effect of quickly opening and closing the side plate 22.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
