Detailed implementation manners

[0045] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0046] As Figures 1-9 shown, the embodiment of the present invention provides a method for curved surface connection of an ultrasonic transducer, including the following steps:

[0047] Step Ⅰ: Clean the outer wall of the cylindrical pipe by using an auxiliary installation device;

[0048] Step Ⅱ: Apply glue locally on the outer wall of the cylindrical pipe;

[0049] Step Ⅲ: Bond one side of the curved surface of the front cover plate of the ultrasonic transducer to the glue-applied part on the outer wall of the columnar pipeline.

[0050] The working principle and beneficial effects of the above embodiments are as follows:

[0051] When installing the ultrasonic transducer on the outer wall of the columnar pipeline, first determine the installation position of the ultrasonic transducer on the outer wall of the columnar pipeline, and then clean the outer wall of the columnar pipeline at the installation position to prevent dirt on the outer wall of the columnar pipeline from causing the ultrasonic transducer to be not firmly pasted. Subsequently, apply glue at the installation position, and finally fit the curved surface of the front cover plate of the ultrasonic transducer to the position where the glue is applied, then the installation of the ultrasonic transducer can be completed, which is time-saving and labor-saving, and one side of the curved surface can better fit the outer wall of the columnar pipeline.

[0052] In one embodiment, in Step Ⅰ, the cleaning includes the following steps:

[0053] a. Fix the auxiliary installation device on the outer wall of the columnar pipeline;

[0054] b. Start the auxiliary installation device to grind and brush the outer wall of the columnar pipeline;

[0055] c. After grinding and brushing, the auxiliary installation device automatically applies glue to the grinding and brushing area.

[0056] In Step c, the area of automatic glue application is equal to the area of the front cover plate.

[0057] In Step Ⅲ, after bonding, use a reinforcement device to reinforce the connection between the ultrasonic transducer and the outer wall of the columnar pipeline.

[0058] The working principle and beneficial effects of the above embodiments are as follows:

[0059] When using the auxiliary installation device to install the ultrasonic transducer, first fix the auxiliary installation device on the outer wall of the pipeline, and then start the auxiliary installation device. Clean the outer wall of the columnar pipeline through the brush of the auxiliary installation device. Subsequently, use the auxiliary installation device to apply glue to the outer wall of the columnar pipeline. When applying glue, the area of glue application is equal to the area of the front end plate of the ultrasonic transducer, which can avoid too large an area of glue application, so that after installing the ultrasonic transducer, there is a large area of glue left on the outer wall of the columnar pipeline, causing adhesion to other objects and accumulation of stains;

[0060] After pasting the ultrasonic transducer on the outer wall of the columnar pipeline, use a reinforcement device for reinforcement. The reinforcement device can be an F-clamp, a splint clamp, etc. Set one side of the F-clamp on one side of the pipeline and the other side on one side of the front end plate. Rotate the screw of the F-clamp to make the front end plate fit more tightly with the outer wall of the columnar pipeline, preventing the ultrasonic transducer from falling off the columnar pipeline after installation.

[0061] In one embodiment, the auxiliary installation device includes a handle 1, a mounting plate 4, a cleaning head, and a drive wheel assembly. The handle 1 is disposed at one end of the mounting plate 4. A cleaning head mounting groove 6 is provided at the end of the mounting plate 4 away from the handle 1. An opening 7 is provided on the side of the cleaning head mounting groove 6 away from the handle 1.

[0062] The drive wheel assembly is disposed on one side of the mounting plate 4 and is used to drive the cleaning head to rotate within the cleaning head mounting groove 6.

[0063] The working principle and beneficial effects of the above embodiment are as follows:

[0064] When using the auxiliary installation device to clean a columnar pipeline, hold the handle 1, bring one end of the mounting plate 4 close to the columnar pipeline, align the opening 7 with the columnar pipeline. After further movement, the cleaning head mounting groove 6 is completely clamped onto the outer wall of the columnar pipeline. Subsequently, start the drive wheel assembly to drive the cleaning head to rotate on the outer wall of the columnar pipeline, that is, perform circumferential cleaning on the outer wall of the columnar pipeline. It is convenient to install, has a high cleaning efficiency, and can perform comprehensive cleaning on the outer wall of the columnar pipeline.

[0065] In one embodiment, the cleaning head includes a pipe fitting 9, a C-shaped slider 10, and a brush 11. The cross-section of the pipe fitting 9 is a C-shaped structure. The C-shaped slider 10 is disposed on one end face of the pipe fitting 9. A C-shaped sliding groove 8 is provided on the outside of the cleaning head mounting groove 6. The C-shaped slider 10 is slidably disposed within the C-shaped sliding groove 8.

[0066] The brush 11 is disposed on the inner wall of the pipe fitting 9.

[0067] A C-shaped gear sleeve is provided on the outer wall of the end of the pipe fitting 9 close to the mounting plate 4, and the C-shaped gear sleeve meshes with the drive wheel assembly.

[0068] The working principle and beneficial effects of the above embodiment are as follows:

[0069] The cross-section of the pipe fitting 9 is a C-shaped structure, enabling the columnar pipeline to enter the interior of the pipe fitting 9 from the opening of the C-shaped structure. When the drive wheel assembly operates, it drives the C-shaped gear sleeve to drive the pipe fitting 9 to rotate on one side of the mounting plate 4. When rotating, the C-shaped slider 10 slides within the C-shaped sliding groove 8 of the mounting plate 4.

[0070] In one embodiment, the drive wheel assembly includes a drive motor, a pulley 14, a first belt 2, a second belt 13, a first gear 3, and a second gear 12. The drive motor is disposed on one side of the mounting plate 4. The pulley 14 is connected to the output shaft of the drive motor. The pulley 14 is connected to the first gear 3 and the second gear 12 through the first belt 2 and the second belt 13 respectively. The first gear 3 and the second gear 12 are spaced apart on one side of the pipe fitting 9. The first gear 3 and the second gear 12 mesh with the C-shaped tooth sleeve.

[0071] The working principle and beneficial effects of the above embodiment are as follows:

[0072] When the drive wheel assembly works, the drive motor works to drive the pulley 14 to rotate on the surface of the mounting plate 4. When the pulley 14 rotates, the first gear 3 and the second gear 12 are driven to rotate through the first belt 2 and the second belt 13. When the first gear 3 and the second gear 12 rotate, they drive the C-shaped tooth sleeve meshing with them to rotate. When the C-shaped tooth sleeve is driven to rotate, it drives the C-shaped slider 10 at one end of the pipe fitting 9 to rotate in the C-shaped chute 8, so that the brush 11 provided on the inner wall of the pipe fitting 9 moves around on the outer wall of the columnar pipe, cleaning the outer wall of the columnar pipe;

[0073] The first gear 3 and the second gear 12 are spaced apart, which can ensure that there is always a gear meshing with the C-shaped tooth sleeve.

[0074] In one embodiment, an automatic glue spreading device is further provided between the handle 1 and the mounting plate 4. The automatic glue spreading device includes a sliding rod 16 and a sliding rail 17. One end of the sliding rod 16 is connected to the sliding rail 17, and the other end is slidably disposed in a through hole 15. The through hole 15 is provided on the side of the mounting plate 4 close to the handle 1;

[0075] A slider 21 is slidably disposed in the sliding rail 17. A steering rod 20 penetrates through the slider 21. One end of the steering rod 20 is provided with a third gear 22. A steering wheel 19 is disposed in the middle section of the steering rod 20. There are two groups of steering wheels 19. The two steering wheels 19 are respectively spaced apart on both sides of the steering rod 20. The steering wheels 19 are slidably disposed in a C-shaped sliding rail 23;

[0076] A rack 18 is disposed on one side of the sliding rail 17 close to the third gear 22. The rack 18 is disposed at one end of the sliding rail 17. The C-shaped sliding rail 23 is disposed at the other end of the sliding rail 17. The C-shaped sliding rail 23 is disposed on the side of the sliding rail 17 close to the steering wheel 19;

[0077] The rack 18 meshes with the third gear 22;

[0078] One end of the steering rod 20 away from the third gear 22 is provided with a brush plate 24 and a nozzle 25, and the brush plate 24 and the nozzle 25 are arranged at intervals on both sides of the steering rod 20.

[0079] The working principle and beneficial effects of the above embodiments are as follows:

[0080] After the cleaning head finishes cleaning the outer wall of a section of the columnar pipeline, since multiple ultrasonic transducers often need to be arranged at intervals on the outer wall of the pipeline, after the cleaning is completed, move the handle 1 to drive the cleaning head to move to the next installation position. Subsequently, move the sliding rod 16 so that the sliding rod 16 slides in the through hole 15. Scale lines can be set on the sliding rod 16 to facilitate the installer to position the installation position. When the sliding rail 17 moves to the position where the cleaning head has finished cleaning, move the slider 21 to drive the steering rod 20 to drive out from the C-shaped sliding rail 23. When moving in the C-shaped sliding rail 23, the two steering wheels 19 are always kept parallel to the C-shaped sliding rail 23 under the action of the C-shaped sliding rail 23. When the two steering wheels 19 drive out from the C-shaped sliding rail 23, the third gear 22 meshes with the rack 18. Subsequently, under the action of the rack 18, the third gear 22 rotates on one side of the slider 21, thereby driving the steering rod 20 to rotate. When the steering rod 20 rotates, it drives the brush plate 24 and the nozzle 25 to rotate 180° around the steering rod 20;

[0081] When the slider 21 drives out from the C-shaped sliding rail 23 and moves towards the rack 18, first the nozzle 25 works to spray glue on the outer wall of the columnar pipeline. When the slider 21 moves from one side of the rack 18 to the direction of the C-shaped sliding rail 23, the nozzle 25 and the brush plate 24 exchange positions so that the slide plate 24 faces the outer wall of the columnar pipeline. As the slider 21 moves, the brush plate 24 spreads the glue sprayed by the nozzle 25 evenly. Compared with manual glue spreading and cleaning, the auxiliary installation device can improve the efficiency of cleaning and glue spreading. At the same time, the pressure of the brush plate 24 on the outer wall of the columnar pipeline is the same as it moves with the slider 21, and the distance between the nozzle 25 and the outer wall of the columnar pipeline is the same, making the glue spreading more uniform.

[0082] In one embodiment, one end of the third gear 22 away from the slider 21 is rotatably provided with an L-shaped rod 27. One end of the L-shaped rod 27 is rotatably connected to the axis of the third gear 22, and the opening of the L-shaped rod 27 faces the sliding rail 17;

[0083] A piston cylinder 28 is provided on the side wall of the rack 18. A piston rod 26 is slidably arranged in the opening of the piston cylinder 28. One end of the piston rod 26 away from the piston cylinder 28 is connected to one side of the L-shaped rod 27, and the piston cylinder 28 cooperates with the piston rod 26;

[0084] One end of the piston cylinder 28 away from the piston rod 26 is provided with a first one-way valve 29 and a second one-way valve 30. The first one-way valve 29 is connected to the nozzle 25 through a pipe, and the second one-way valve 30 is connected to a glue tank through a pipe.

[0085] The working principle and beneficial effects of the above embodiments are as follows:

[0086] When driving the slider 21 to move, hold one end of the L-shaped rod 27 and drag the L-shaped rod 27, so that the L-shaped rod 27 drives the third gear 22 to move. When the third gear 22 moves from one side of the C-shaped slide rail 23 to the rack 18, the movement of the L-shaped rod 27 causes the piston rod 26 to move in the piston cylinder 28, squeezing the glue in the piston cylinder 28, so that the glue is sprayed from the nozzle 25 to the outer wall of the columnar pipe through the pipe. When the L-shaped rod 27 moves to the side away from the rack 18, the L-shaped rod 27 drags the piston rod 26 to move in the piston cylinder 28, reducing the pressure in the piston cylinder 28. At this time, the first one-way valve 29 closes and the second one-way valve 30 opens, and the glue in the glue tank enters the piston cylinder through the pipe from the second one-way valve 30. When the piston rod 26 moves towards the piston cylinder 28, the second one-way valve 30 closes and the first one-way valve 29 opens;

[0087] It can automatically replenish the glue in the piston cylinder 28 and spray the glue in the piston cylinder 28 through the nozzle 25.

[0088] In one embodiment, the ultrasonic transducer includes a front cover plate 31 and a transducer body 32. The front cover plate 31 is arranged at one end of the transducer body 32, and a C-shaped curved surface 33 is arranged on the surface of the front cover plate 31 away from the transducer body 32. The C-shaped curved surface 33 is used to fit the outer wall of the columnar pipe fitting.

[0089] The working principle and beneficial effects of the above embodiments are as follows:

[0090] The transducer body 32 is arranged on one side of the plane of the front cover plate 31. During installation, the C-shaped curved surface side of the front cover plate 21 is attached to the outer wall of the columnar pipe, which can make the front cover plate 31 better fit the arc-shaped outer wall and is convenient for installation.

[0091] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
