[0002] The transducer unit array is composed of two primitives as a unit array, and four unit arrays are simulated and combined into a strip array. The weight of a single unit array reaches 20 kilograms. The strip array formed by the combination of four unit arrays is large in size and heavy in weight. Therefore, the minimum unit measurement method is adopted in the measurement of the acoustic performance of the transducer, that is, a single unit array is measured once. The entire base array contains 128 groups of unit arrays, which is a large number. The current measurement and installation method is: one person holds the unit array with both hands to align the assembly holes on the unit array with the assembly holes on the measuring tool, and the other person cooperates to assemble with bolts. There are 4 assembly holes on a tool that need to be installed with screws. The replacement of this measurement tool is time-consuming and labor-intensive, which is not conducive to measuring a large number of unit arrays one by one, and the required installation space is relatively large.

[0003] Among them, the announcement number CN206629273U discloses a transducer unit array measurement tool, especially a transducer unit array measurement tool.
