Embodiment Construction

[0040] figure 1is a schematic structural diagram of the energy harvesting device 100 of the triboelectric nanogenerator 170 according to an embodiment of the present invention. For example, the energy harvesting device 100 can be combined with an existing ocean power station, and the energy harvesting device 100 is placed at the bottom of the power station to collect tidal energy. Such as figure 1 As shown, the energy harvesting device 100 may include a deformable and / or compressible housing. The housing may include a shoulder 110 , a neck 120 , side walls 130 and a bottom wall 140 . The neck 120 extends upwardly from the inner edge of the shoulder 110 and is hollow in such a way that the neck 120 defines a first cavity 150 in which the triboelectric nanogenerator 170 is disposed. The sidewall 130 extends downward from the outer edge of the shoulder 110 . The bottom wall 140 is connected to the bottom of the side wall 130 and is configured to be airtight. The bottom wall ...

Abstract

The invention provides an energy collecting device of a friction nano generator. The device comprises a flexible and / or compressible casing, wherein the casing comprises a shoulder portion, a neck portion extending upwards from an inner side edge of the shoulder portion, a side wall extending downwards from an outer side edge of the shoulder portion, and a bottom wall, wherein the neck portion is a hollow structure to form a first chamber defined on the neck portion, the friction nano generator is arranged in the first chamber, a second chamber is defined by the bottom wall and the side wall, a material of the bottom wall is a flexible material to make the bottom wall generate deformation under external force, the second chamber is communicated with the first chamber to make air of the second chamber be led to the first chamber when the bottom wall deforms or air of the first chamber is pumped to the second chamber when the bottom wall deforms, the friction nano generator is driven to work during air flowing, and external mechanical energy is converted into electric energy. The device is advantaged in that energy collecting efficiency is high, and sealing property of the side wall and the bottom wall are good.

Description

technical field [0001] The invention relates to an energy collection device, in particular to an energy collection device for a friction nanogenerator. Background technique [0002] The ocean is a huge energy treasure house, and its energy is sufficient to meet the energy needs of the entire human being. The collection of ocean energy is mainly to collect its periodic kinetic energy, mainly including tides, waves, ocean currents, etc. At present, its collection is mainly based on electromagnetic induction, but there are many disadvantages in this method: First, the electromagnetic induction generator is mainly composed of a magnet and a coil with a large mass, so that the entire device cannot float on the surface of the water body, and it needs to rely on a Secondly, electromagnetic coils and magnets cannot withstand long-term seawater corrosion, and their resistance to seawater corrosion is poor; thirdly, electromagnetic generators can only collect energy from directional c...
