Description

technical field [0001] The invention relates to the technical field of energy conversion, in particular to an environmental mechanical energy composite collection and conversion device. Background technique [0002] Environmental mechanical energy refers to the kinetic energy and potential energy in the surrounding environment, such as wind energy, wave energy, raindrop energy, vibration energy, etc. The kinetic energy formed by the air flow caused by the uneven heating of the earth's surface is wind energy, and the global wind energy is about 2.74*10 9 MW, of which the available wind energy is 2*10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth; wave energy refers to the kinetic energy and potential energy of ocean surface waves. 70.8% of the earth's area is covered by seawater, and ocean waves are rich in energy resources . Nowadays, the human demand for energy continues to increase, and the reserves of non-...

Problems solved by technology

[0003] At present, energy harvesting in the environment is mainly carried out in the form of large wind power generators, large tidal power generators, hydropower stations, etc. Most of them have strict environmental requirements. Power supply requirements for low-power portable devices and sensor nodes; in terms of small-scale dynamic and potential energy collection and conversion, there have been some design inventions, but they are generally single application scenarios, such as only placed somewhere outdoors to collect wind energy or only It is used to be placed somewhere on the sea to collect wave energy, etc. It has more environmental requirements, poor applicability, and poor compatibility, which greatly limits its scope of use, and most of the devices are in a single power conversion mode, relying only on electromagnetic The conversion method or only rely on the triboelectric method to output electric energy, and due to the limitation of a single conversion mode (the conversion efficiency of the electromagnetic conversion method is low in a low-speed motion environment, although the triboelectric form also has a high conversion efficiency at a low speed, the overall power The output is small), and the power output efficiency is generally not high

[0004] Therefore, how to avoid the inability to efficiently output electric energy due to the use of a single conversion mode is a technical problem currently to be solved by those skilled in the art
