Ultrasonic transducer mounting apparatus for attaching a transducer block to a pipeline
A transducer mounting apparatus can be used to remotely monitor the integrity of pipes or pipelines, which ordinarily are difficult to access due to environmental factors. The transducer mounting apparatus can include one or more transducer blocks, each adapted for receiving a transducer. A UT couplant and threaded transducer are positioned in an opening in the transducer block. A gear wheel adjusts the transducer up and down against the UT couplant to optimize the positioning relative to the pipe being monitored. A series of transducer blocks are connected by a tension block and or more wire ropes extending through the tension block and the transducer blocks. The length of the wire rope is adjusted with a set screw extending from the tension block to a transducer block, thereby allowing the transducer block assembly to accommodate different pipe diameters or mechanical structures of varying dimensions that are not necessarily round.
1. An apparatus, comprising: a transducer block having a top surface, a bottom surface, and side surfaces disposed to be perpendicular to the top and bottom surfaces of the transducer block, wherein the transducer block has an opening on its top surface and a slot arranged perpendicular to the opening, the slot having a slot opening on one of the side surfaces of the transducer block; and
a gear wheel having an opening in a middle portion thereof, the gear wheel being secured in the slot and protruding from the slot opening of the transducer block, wherein a transducer is positioned in the opening of the gear wheel, and the gear wheel is configured to rotate to move the transducer vertically up or down relative to a solid ultrasonic (UT) couplant positioned in the transducer block.
2. The apparatus of claim 1 , further wherein the transducer block comprises one or more openings in the bottom surface adapted for receiving a magnet.
3. The apparatus of claim 1 , wherein the transducer is threaded.
4. A transducer mounting apparatus, comprising:
one or more transducer blocks, each transducer block having an opening on its top surface and a slot arranged perpendicular to the opening, the slot having slot openings on opposing side surfaces of each of the transducer blocks, the side surfaces are disposed to be perpendicular to the top surface of each of the transducer blocks;
a gear wheel having an opening in a middle portion thereof, the gear wheel being secured in the slot and protruding from the slot openings of each transducer block, wherein a transducer is positioned in the opening of the gear wheel, and the gear wheel is configured to rotate to move the transducer vertically up or down relative to a solid ultrasonic (UT) couplant positioned in each of the transducer blocks; and
a tension block positioned adjacent to at least one of the opposing side surfaces and connected to the one or more transducer blocks by one or more wire ropes.
5. The transducer mounting apparatus of claim 4 , further comprising a dowel pin for connecting the tension block to one or more of the transducer blocks.
6. The transducer mounting apparatus of claim 4 , further comprising a magnet positioned in a hole in the transducer block for securing the transducer block to a metal surface.
7. The transducer mounting apparatus of claim 4 , further comprising a set screw extending from the tension block to the transducer block, wherein the set screw adjusts the length of the one or more wire ropes.
8. The transducer mounting apparatus of claim 4 , wherein the transducer is threaded.
9. The transducer mounting apparatus of claim 4 , wherein the transducer can be activated and monitored remotely.
10. The transducer mounting apparatus of claim 4 , further comprising a transducer array shroud positioned over the transducer mounting apparatus and section of pipe to which the transducer mounting apparatus is secured.
11. An apparatus, comprising:
a transducer block having a top surface and a bottom surface, wherein the transducer block has an opening on its top surface and a slot arranged perpendicular to the opening, the slot having slot openings on opposing side surfaces of the transducer block, the side surfaces are disposed to be perpendicular to the top surface of each of the transducer blocks; and
a gear wheel having an opening in a middle portion thereof, the gear wheel being secured in the slot and protruding from the slot openings of each transducer block, wherein a transducer is positioned in the opening of the gear wheel, and the gear wheel is configured to rotate to move the transducer vertically up or down relative to a solid ultrasonic (UT) couplant positioned in the transducer block.
