采用风光互补供电的小型传感器无需定期更换电源，可部署在各类人迹罕至地区，然而在实际应用中光伏组件容易受到污垢沉积导致发电功率降低，小型风力发电机的旋转部件也极易出现故障。设计了一种结构较为简单且具有自清洁功能的风-光互补取电装置，结合气象统计数据对装置的太阳能和风能取电性能进行了实验测试，比较了不同灰尘覆盖量下光伏组件的振动清灰性能。研究结果表明该装置在模拟晴朗天气下（光照强度948.1 W/m²）下太阳能收集可产生77.28 mW的最大输出功率；基于压电效应的风致涡激振动取电启动风速在1.5 m/s左右，实验条件下4.3 m/s风速可以产生4.63 mW的输出功率；通过风致振动对不同灰尘覆盖量的光伏组件清灰后，太阳能收集输出功率能恢复到清洁状态下的84%以上。该研究为偏远地区无维护的小型微功率发电设备提出了新的技术方案。

Small sensors powered by wind-solar hybrid power supply do not require regular replacement of the power supply, and can be deployed in various remote areas. However, in practice, the photovoltaic panels are prone to accumulation of dirt, resulting in reduced power generation, and the rotating parts of small wind turbines are also very prone to failure. A wind-solar hybrid power device with a simple structure and self-cleaning capability was designed, and its solar and wind energy collection performance was experimentally evaluated based on meteorological statistical data. Moreover, the vibration cleaning efficacy of the photovoltaic panels under various dust coverage levels was compared. The research results show that the device can generate a maximum output power of 77.28 mW under simulated clear weather conditions (light intensity of 948.1 W/m²). The starting wind speed of wind energy collection based on piezoelectric and vortex-induced vibration effects is around 1.5 m/s, and a wind speed of 4.3 m/s in the experiments can generate an output power of 4.63 mW. After vortex-induced vibration cleaning of the photovoltaic module with different dust coverage densities, the output power of solar energy collection can be restored to over 84% of the clean state. This study presents a new technical solution for maintenance-free small-scale micro power generation equipment in remote areas.
