Description

Technical Field

[0001] The utility model relates to the technical field of sensor installation, in particular to an adjustable installation and fastening device for a pipeline sensor. Background Art

[0002] Ultrasonic thickness measurement technology is one of the important means to monitor the corrosion and thinning of metal pipelines. Ultrasonic thickness measurement sensors are one of the main applications of this technology. They can monitor the changes in wall thickness data of metal pipelines caused by corrosion in real time, and then take corresponding corrosion protection measures in time to ensure the service life of the pipeline.

[0003] Ultrasonic thickness sensors based on piezoelectric ultrasonic technology need to be adhered to the surface of metal pipes with adhesives. At the same time, the adhesive can fill the gap between the sensor and the pipe surface, acting as a coupling agent to improve the sensor signal quality and signal strength. However, the pipe surface is curved and the sensor surface is flat. It is difficult to adjust the sensor installation angle and fix the position during the installation process. It takes time for the adhesive to cure when installing the sensor, and the sensor position needs to be kept fixed during this period to ensure that the adhesive cures smoothly. At the same time, a certain amount of pressure needs to be applied to the sensor. While the adhesive fully fills the gap, the excess adhesive is squeezed out of the gap to ensure that the sensor fits tightly with the metal pipe, thereby ensuring the sensor signal quality and signal strength. The above problems increase the difficulty of installing pipeline thickness sensors and reduce the efficiency of sensor installation. Utility Model Content

The second half-body 2 is used to surround the other half of the circumferential outer wall of the pipe 01. The second half-body 2 is provided with a second connecting portion 21 at both ends. The bolt 3 connects the first connecting portion 12 and the second connecting portion 21, and the specification of the bolt 3 can be selected according to the size of the first connecting portion 12 and the second connecting portion 21. In this embodiment, the angle of the installed sensor 02 can be adjusted by adjusting the screw-in length of the bolts 3 on the left and right sides, and the contact pressure between the sensor 02 and the pipe 01 can be adjusted by adjusting the torque of the bolts 3, thereby improving the coupling effect between the sensor 02 and the pipe 01.

[0029] In this embodiment, the first half-tied body 1, the accommodating portion 11 and the second half-tied body 2 are made of plastic materials (such as nylon-66, polytetrafluoroethylene, etc.) that can withstand the operating temperature, have a certain degree of flexibility, and have good weather resistance. The length and width can be adjusted according to the diameter of the installed pipe 01, and are compatible with pipes 01 of different diameters.

[0030] Specifically, the accommodating portion 11 is open at one end close to the outer wall of the pipe 01, and the accommodating portion 11 is used to cover the sensor 02 from the upper end of the sensor 02. The upper end and the side wall of the accommodating portion 11 can position the sensor 02. Furthermore, the accommodating portion 11 adopts a net bag structure, and the middle net bag structure is used to fix the sensor 02, and the shape can be adjusted according to the size of the sensor 02.

[0031] Furthermore, the first connecting part 12 is in a rectangular shape, the first connecting part 12 is hollow, the first half-tied body 1 is connected to the inner side of the upper surface of the first connecting part 12, the inner side and the lower side of the first connecting part 12 are open, and the upper surface of the first connecting part 12 is provided with a through hole.

[0032] Furthermore, the second connecting part 21 is in the shape of a rectangular parallelepiped, the second connecting part 21 is hollow, the second half-tied body 2 is connected to the inner side of the lower surface of the second connecting part 21, the inner and outer sides of the second connecting part 21 are open, a threaded hole is provided on the upper surface of the second connecting part 21, the upper end of the second connecting part 21 is inserted into the first connecting part 12, and the bolt 3 passes through the through hole of the first connecting part 12 and is threadedly connected to the threaded hole of the second connecting part 21.

[0033] Furthermore, the bolt 3 is made of a metal material with good corrosion resistance (such as 304, 316, 316L and other stainless steel).

[0034] The working process of this embodiment:

[0035] Grind and remove rust from the position to be measured on the metal pipe 01. The size of the grinding area should be consistent with the measuring surface of the sensor 02.

[0036] Apply adhesive to the position to be tested, and stick the sensor 02 to the position to be tested on the metal pipe 01;

[0037] Use the net bag structure of the first half-body 1 to cover the sensor 02, and install the second half-body 2 in place with the first half-body 1, and use bolts 3 to connect the upper and lower parts of the device;

[0038] Screw in the bolts 3 on both sides simultaneously to a certain torque, so that the upper and lower parts of the fastening device are slightly tensioned, and then adjust the angle of the sensor 02 and fix the position of the sensor 02 by adjusting the screwing length of the bolts 3 on both sides;

[0039] Further tighten the bolts 3 on the left and right sides synchronously to gradually squeeze out the excess adhesive from the contact surface between the sensor 02 and the metal pipe 01;

[0040] While tightening bolt 3 to adjust the torque, use the sensor 02 signal detection device to check the sensor 02 signal quality and signal strength until the required coupling effect index is reached;

[0041] After the installation is completed, wait for the adhesive to completely cure, and the adjustable fastening device of sensor 02 can be selectively removed according to needs (for example, in extremely bad weather, in order to prevent the sensor 02 from falling off due to external forces, you can choose not to remove the device, which plays a role in assisting in fixing the sensor 02).
