AI Technical Summary

Technical Problem

Existing density testing equipment cannot integrate sampling and testing, and is prone to instability of electronic balances due to external factors, affecting measurement accuracy.

Method used

A density testing device was designed, comprising a shell, a solution tank, a sampling blade, a stepper motor, and a bevel gear transmission system. After sampling by the sampling blade, the sample directly enters the solution tank for density testing, and is analyzed using a photoelectric identification and imaging system. Combined with a spiral rod and buffer spring structure, the sampling and testing operations are integrated.

Benefits of technology

It achieves efficient integration of sampling and testing, improves detection efficiency, ensures the integrity of cable protection pipes and measurement accuracy, and avoids equipment vibration and friction damage.
