Abstract

The present invention proposes a TENG collection device that can synergistically collect wind and rain energy at the same time. The energy harvesting device can adapt to changes in wind direction and has a waterproof function. The water baffle and the inclined surface play a shielding role on the frictional nanogenerator that collects wind energy downwards, preventing rainwater from interfering with the frictional nanogenerator that collects wind energy. The vane structure of the frictional nanogenerator that collects wind energy plays a role in adjusting the wind direction. When the direction of the wind changes, the structure can timely adjust the device to face the direction with the strongest wind force to improve the utilization rate of wind energy. The device of the present invention can act synergistically, improving the effect of synchronous collection of wind and rain energy, and the worse the weather, the greater the wind speed and rain speed, and the more obvious the synergistic effect.

Description

technical field [0001] The invention belongs to the field of wind and rain energy friction nano generators, in particular to a wind and rain energy collection device based on friction nano generators. Background technique [0002] Triboelectric nanogenerator (TENG), a new type of generator capable of harvesting energy from almost all environmental mechanical motions, has been extensively studied because of its ability to meet multi-scale energy demands, wind and raindrops are two common Energy, based on TENG, a series of wind energy harvesting devices have been developed and a series of raindrop energy harvesting devices have also been developed. However, a TENG that can automatically harvest energy from both wind and raindrops is indeed rare. Moreover, the simultaneous existence of wind and rain is more complicated. Humidity and moisture will seriously affect the output performance of TENG, resulting in a decrease in its output energy. On the other hand, the wind will inte...
