Abstract
Description
Technical Field
[0001] The utility model relates to a power generation device, in particular to a solar power generation device with a surface cleaning function. Background Art
[0002] Of all available electricity sources, solar photovoltaic (PV) is the most widely installed and used energy source. The Xinjiang Seismic Network has a total of 105 seismic stations. Because most of Xinjiang's field stations are located far from utility power points, rural utility power is unstable, and installing dedicated power lines is difficult, 98% of these stations use solar power.
[0003] Solar panels convert sunlight into electricity, which is then stored in batteries via a solar controller. These batteries then output DC power to the loads, depending on the needs of the station's instruments and equipment. Because field seismic stations are often located in remote, sparsely populated areas, solar mounts are often constructed from welded angle iron. These mounts are secured to the top of the station using welding and expansion screws, providing both theft protection and minimizing obstruction to the solar panels.
[0004] Currently, research on photovoltaic panel photoelectric conversion efficiency primarily focuses on power generation technology and materials. External factors can easily reduce photovoltaic power generation efficiency. Statistics show that external factors can reduce the utilization rate of solar panels from 23%-25% to 17%-18%. Furthermore, hot spot effects can exacerbate the aging of photovoltaic panels, severely impacting their service life. Common external factors include dust, snow, and ice. If dust, snow, and ice covering solar photovoltaic panels are not promptly removed, they will reduce the charge of the photovoltaic cells. Consequently, if continuous cloudy weather persists, observatory stations may experience power shortages, causing equipment to cease operation. Conventional snow removal methods include manual snow plowing, mechanical snow removal, nano-self-cleaning coatings, and electric heating. Currently, station maintenance personnel can only manually plow snow, as nano-technology coatings are expensive and electric heating consumes a lot of electricity. Furthermore, the observation site is located far from the city, making manual snow removal costly. In existing technologies, flat solar panels are often placed on rooftops or inaccessible areas during use, making them difficult to clean when snow falls. Snow cover blocks the panels from sunlight, reducing their efficiency. Excessive snow accumulation can damage the panels' surfaces, leading to equipment damage and shortening their service life. Existing solar-powered dust removal devices are not suitable for snow removal, and the power generation mechanisms capable of snow removal are often difficult to adjust. Therefore, a solar power generation device with a surface cleaning function is proposed. Utility Model Content
