Description

Net-shaped power generation device based on nano power generation and E-ACE material

Technical Field

The utility model relates to a power generation facility especially relates to a netted power generation facility based on nanometer power generation and E-ACE material.

Background

Under the global crisis conditions of climate warming and energy crisis, wind energy is widely regarded as important renewable green energy as important mechanical energy presented by nature, but the traditional wind power generation technology based on the electromagnetic induction power generation technology has the problems of large volume, large mass, high cost, difficult low-wind-speed driving and the like. Although the bimorph transducer structure solves the defect of low starting speed of the traditional wind power generation to a certain extent, the bimorph transducer structure is complex in structure and low in output efficiency, and is difficult to be widely applied under the condition of low wind speed. Therefore, the development of a novel wind power generation technology and the popularization of the novel wind power generation technology in a larger application range (especially in a weak wind environment) and the daily life of people have great necessity and practical significance.

Zhao et al designs a 2D structure independent braided triboelectric nanogenerator (WTENG) flag, which can obtain high altitude wind energy from any direction, and when the matching resistance is 6.5 mq, the maximum value of the output peak power density reaches 135 mw/kg. It was found that this 2D WTENG flag can also be superimposed in parallel connections of multiple layers to achieve a linearly increasing output. In addition, the WTENG flag is light in weight, low in cost, easy to expand and has a huge application prospect in a weather/environment sensing/monitoring system.

In nature, the direction and frequency of most mechanical vibrations are not fixed, and thus it is difficult to efficiently perform energy harvesting. Yang works in both vertical-contact separation mode and horizontal sliding mode by proposing a TENG with a three-dimensional structure. The investigators performed 3 practical application studies. Group 1 is a three-dimensional TENG mounted on a cable, and the collected vibrational energy can effectively illuminate 40 LEDs under the small disturbance of wind or rain. The 2 nd group is to bind the three-dimensional TENG on the human leg, and can effectively light 40 commercial LEDs by collecting the vibration energy of the human body in the walking process. Group 3 fixes a three-dimensional TENG to the bicycle wheel, and 30 commercial LEDs in series can be lit directly during wheel rotation. The research shows that TENG has certain practicability in daily life, and is expected to be widely applied in the future based on the characteristics of small volume, various structures, environmental protection, no pollution and the like.

However, the above structures all have the defects of higher manufacturing cost, lower utilization rate of natural energy such as wind energy and the like, smaller generated energy and incapability of being applied to high-power electric equipment.
