Abstract

The invention discloses a pole tower resonance energy acquisition device, which comprises a completely enclosed shell installed on a power transmission pole tower, a simple harmonic vibration mechanism arranged in the shell, and an energy acquisition device for converting the kinetic energy of the simple harmonic vibration mechanism into the electric power to be outputted. The simple harmonic vibration mechanism vibrates synchronously with the power transmission pole tower. The simple harmonic vibration mechanism comprises at least one mass block and a flexible confinement mechanism for restraining the mass block to perform simple vibrations within a certain scope in a specific direction. The device of the invention is simple, portable and can be widely used. Through the adjustment of the parameters of the vibration system, including the stiffness coefficient and the mass, frequency adaptability can be realized so that it can be applied to environments with different vibration frequencies to provide power to small power consumption equipment stably.

Description

technical field [0001] The invention relates to the field of on-line monitoring of power transmission poles and towers and the field of vibration energy harvesting, in particular to a resonance energy harvesting device applied to small power consumption equipment on power transmission poles and towers. Background technique [0002] With the development of network monitoring and artificial intelligence in the power grid system, there are more and more condition monitoring equipment on the tower, and many electronic products including sensors and communication machines need sufficient and stable power supply. Therefore, it is necessary to use various environmental energies around it and introduce a new power supply method (vibration energy). [0003] The energy and output stored in various resonance phenomena in nature are more efficient and considerable than other types of vibrations, which is especially evident on transmission towers. Due to natural frequency and wind-induc...
