This utility model relates to the field of electrical energy detection technology, and proposes a high-current electrical energy detection device with closed-loop control function. The device includes: a programmable power source module, including an output drive unit for outputting current, voltage signals, and waveforms within a large current range; a standard measurement module connected to the output drive unit for detecting the current, voltage signals, and waveform parameters output by the output drive unit; a waveform sampling module connected to the output drive unit for sampling the waveform output by the output drive unit; a closed-loop control module bidirectionally connected to the programmable power source module and the waveform sampling module for adjusting the current, voltage signals, and waveforms; and an external device detection interface connected to the output terminal of the output drive unit for connecting different types of high-current metering devices. This utility model solves the problems of measurement error superposition, unstable output, and insufficient measurement range in traditional detection devices.

This utility model relates to the field of pile foundation testing technology and discloses an underwater pile foundation testing mechanism for bridges. It includes a pile foundation body, a winding assembly on one side of the pile foundation body, a testing device below the winding assembly, a camera inside the testing device, and a cleaning assembly on top of the testing device. The winding assembly includes a float on one side of the pile foundation body, a mounting base fixedly connected to the top of the float, a motor fixedly connected to the right side of the mounting base, a winding drum fixedly connected to the motor's output end, and two pulleys fixedly connected to the left side wall of the mounting base. This utility model, through the structural design of the winding assembly, solves the problems of existing technologies where the testing device is lowered into the water using a telescopic rod, the adjustment of the telescopic rod is cumbersome, requiring testing personnel to spend a lot of time and effort on adjustments, and the telescopic rod is not convenient for adjusting all lengths.
