AI Technical Summary
Technical Problem
Existing sensors are prone to causing damage to the transmission tower structure during installation and are difficult to use for high-precision strain measurement.
Method used
A strain measurement rod device for iron towers was designed, including components such as a sensor pretensioner, a prestressed sleeve, a connecting pipe, a connecting rod, and a fixing plate. The sensor is pre-tightened and fixed through a threaded structure and a disc spring, which avoids damage to the iron tower structure and improves operability and adjustment range.
Benefits of technology
It achieves high-precision strain measurement of the sensor, avoids damage to the tower structure, is easy to operate, highly adaptable, and can flexibly adjust the size to ensure safety and stability.
