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.

[0029] Please see Figures 1-7 .

[0030] To address the problem that existing anti-scaling measures often involve the use of chemical reagents, which can cause significant damage to pipelines and affect their lifespan, this solution proposes an ultrasonic online anti-scaling device for sewage pipelines in oilfield joint stations. The device comprises a support frame 1, a sewage delivery pipe 2 housed within the support frame 1, and a movable ring 5 fitted onto the outer surface of the sewage delivery pipe 2. Multiple vibration anti-scaling mechanisms are arranged at equal angles inside the movable ring 5. Each vibration anti-scaling mechanism consists of an ultrasonic transducer 6 installed inside the movable ring 5, a vibrating plate 7 connected to the ultrasonic transducer 6, a vibrating spring 8 positioned between the movable ring 5 and the vibrating plate 7, and vibrating beads 9 attached to the outer surface of the sewage delivery pipe 2. A gear 12 is rotatably mounted in the center of a movable plate 10, with a long strip plate 13 meshing at its upper end. The movable plate 10 is fixed to the upper end of the movable ring 5. The movable plate 10, along with the gear 12 and the long strip plate 13, drives the movable ring 5 to reciprocate left and right on the outer surface of the sewage delivery pipe 2.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the sewage conveying pipe 2 is placed in the support frame 1, and fixed clamps 3 are provided at both ends of the sewage conveying pipe 2. Rubber clamping teeth 4 are provided on the inner side of the fixed clamps 3. The fixed clamps 3 drive the rubber clamping teeth 4 to stably clamp the sewage conveying pipe 2. Moreover, the fixed clamps 3 at the upper and lower ends are fixed together by fastening bolts, thereby fixing the sewage conveying pipe 2 in the support frame 1. Figure 1 , Figure 4 and Figure 5 As shown, a movable ring 5 is fitted on the outer surface of the sewage conveying pipe 2, and multiple vibration anti-scaling mechanisms are set at a medium angle on the movable ring 5. The vibration anti-scaling mechanism is composed of an ultrasonic transducer 6 installed inside the movable ring 5, a vibrating plate 7 connected to the ultrasonic transducer 6, a vibration spring 8 set between the movable ring 5 and the vibrating plate 7, and vibrating beads 9 attached to the outer surface of the sewage conveying pipe 2. The ultrasonic transducer 6 is connected to an external ultrasonic generator. During use, the external ultrasonic generator is activated, and the ultrasonic generator, together with the ultrasonic transducer 6, drives the vibrating plate 7 to extend and retract within the movable ring 5. Combined with the setting of the vibration spring 8, the vibrating beads 9 attached to the outer surface of the sewage conveying pipe 2 are driven to vibrate, thereby knocking and vibrating the outer surface of the sewage conveying pipe 2, thus effectively removing and preventing scale buildup on the inner wall of the sewage conveying pipe 2. Moreover, the entire descaling process will not damage the sewage conveying pipe 2, thus extending the service life of the sewage conveying pipe 2.

[0032] During the descaling process, such as Figure 1 , Figure 2 ,Figure 6 and Figure 7 As shown, the forward and reverse motor 11 installed on the front side of the movable plate 10 is started. The forward and reverse motor 11 drives the gear 12 to rotate in the middle of the movable plate 10, and the upper end of the gear 12 is engaged with the long strip plate 13 fixed to the top of the inner side of the support frame 1, thereby driving the movable plate 10 to slide left and right between the support frame 1. At the same time, the movable plate 10 drives the moving wheel 14 to roll on the upper end of the support frame 1. The moving ring 5 is fixed to the lower end of the movable plate 10. The movable plate 10 drives the moving ring 5 to move left and right on the outer surface of the sewage conveying pipe 2, thereby descaling various positions of the sewage conveying pipe 2. In addition, the lower end of the moving ring 5 is fixedly connected to the connecting column 15. During the movement, the moving ring 5 drives the connecting column 15 to slide left and right between the long rail 16, thereby further improving the stability of the moving ring 5 during the movement, providing support and limiting for the moving ring 5, and preventing deviation.
