Description

Technical Field

[0001] The utility model relates to the technical field of power generation, in particular to a breeze collection power generation device. Background Art

[0002] Wind turbines or solar power generation are usually used to meet independent energy needs in the wild. However, such technical equipment is bulky, occupies a large volume, is not easy to carry, and has high construction and installation costs. Therefore, there is an urgent need to develop reliable, applicable and efficient power generation technologies for outdoor energy needs.

[0003] The patent document with publication number CN 110445304 B discloses a field mechanical energy collection device based on a friction nanogenerator, including a power part, a transmission part, an electrification part and a support part. The power part can be a wind cup, a turbine, a hand-cranked component or any combination of the two, which can convert external mechanical energy such as wind energy, water energy and manpower into the rotational energy required by the device. The transmission part mainly transmits the obtained rotation to the electrification part through shaft system components, so that the electrification materials can be electrified by mutual friction. The electrification part includes three friction layers, an outer layer, a middle layer and an inner layer, which are electrified by mutual friction. The support part plays the role of fixing and supporting the device. The utility model realizes the collection of low-frequency mechanical energy in nature based on the principle of friction nanogenerator, making continuous power supply for field operations possible.

[0004] The patent document with publication number CN 115347813 A discloses a friction nano power generation device based on an unpowered wind hood. The friction nano power generation device based on an unpowered wind hood of the utility model comprises an unpowered wind hood and a friction power generation unit; the friction nano power generation unit of the utility model utilizes the mutual rotation of the rotor and stator of the wind hood, and generates electricity through the repetitive friction between the friction block and the electrode one and the electrode two, thereby realizing the conversion of wind energy into electrical energy. Based on the characteristic that the wind hood is relatively sensitive to wind force, the utility model utilizes air convection to realize the rotation of the driving device, which does not affect the original function of the wind hood, and can also realize the collection of wind energy and convert it into electrical energy. The utility model can be used in a wide range of scenarios and has strong applicability.

[0005] The above patent generates electricity through friction nano-power generation technology and is driven by wind power. However, the power generation efficiency of friction power generation only through the contact between the friction block and the electrode is low. At the same time, it is not convenient to disassemble and repair during use, and is not convenient for daily maintenance. Utility Model Content
