AI Technical Summary

Technical Problem

In the "sand and barren" environment, traditional unidirectional blade wind turbines have a wide wind speed range and frequent wind direction changes, resulting in insufficient stability of the power supply for sensors to obtain wind power, making it difficult to guarantee a reliable power supply for line monitoring sensors.

Method used

The device employs an all-directional bladeless wind-gathering and energy-harvesting system, which includes an all-directional wind-gathering and acceleration mechanism and a bladeless wind-powered energy harvesting mechanism. It achieves 360° wind energy collection through an all-directional air intake and collection component and a converging and accelerating tubular flow channel. It utilizes the Venturi effect to accelerate the incoming airflow and converts vibration energy into electrical energy through the bladeless wind-powered energy harvesting mechanism. The energy is then stored and output in conjunction with a power management module.

Benefits of technology

It improves the wind energy collection range and efficiency, reduces the starting wind speed, enhances the stability and reliability of sensor power supply, and avoids the high mechanical failure rate and easy damage problems of traditional blade-type energy harvesting devices.
