Rural domestic energy gathering photovoltaic temperature-pressure power generator

Abstract

A rural domestic energy gathering photovoltaic temperature-pressure power generator comprises a light converging and energy gathering device, a photovoltaic temperature-pressure power generation device, a temperature sensor, an illumination intensity sensor and an electronic control device. The light converging and energy gathering device is arranged on the periphery of the photovoltaic temperature-pressure power generation device and makes solar energy converge on the photovoltaic temperature-pressure power generation device. The temperature sensor is arranged in the photovoltaic temperature-pressure power generation device and detects the temperature in the photovoltaic temperature-pressure power generation device. The illumination intensity sensor is arranged at one end of the photovoltaic temperature-pressure power generation device and detects the illumination intensity of the toward-light face of the photovoltaic temperature-pressure power generation device. The electronic control device is electrically connected with the temperature sensor, the illumination intensity sensor, the photovoltaic temperature-pressure power generation device and the light converging and energy gathering device. The electronic control device adjusts the rotation and deviation of the light converging and energy gathering device in real time according to the signal data of the temperature sensorand the illumination intensity sensor and provides proper solar radiation energy density for the photovoltaic temperature-pressure power generation device. Electric demands for modern production and life of rural families under different geographic and geomorphic conditions can be met.

However, coal-fired thermal power is still the mainstay at present. Thermal power uses mineral energy coal to burn and convert it into steam energy for power generation, which produces a large amount of greenhouse gas CO 2 and SO 2 , CO, NOx and unburned hydrocarbons, destroying the earth's ecological environment, and losing about two-thirds of the energy in the process of converting fuel into electricity

In the field of clean energy, large-scale photovoltaic power generation has been widely used at present, but one requires a vast land without sunlight, occupies a large area, and requires a large investment. It is extremely difficult to select a site in many rural areas where land resources are scarce; the other is , the highest utilization rate of light radiation in existing photovoltaic power generation can only reach about 26%, generally only 12% to 15%, most of which are converted into heat energy, which not only affects the power generation efficiency of photovoltaic power generation devices, but also easily causes high temperature, affecting photovoltaic panels. Life expectancy; three, due to the disorderly distribution of trees and buildings in the countryside, the time of photovoltaic power generation is shortened and the light is often blocked, which makes it impossible to effectively use the time of solar power generation and efficiently maintain the efficiency of photovoltaic power generation; four, photovoltaic power generation is greatly affected by temperature , so that photovoltaic power generation is still unable to break through the limitation of light radiation intensity of photovoltaic power generation; in addition, photovoltaic power generation is affected by changes in light radiation intensity, showing periodicity, intermittent and randomness, and its characteristics will not only affect power generation, but also may cause all The voltage fluctuation and flicker of power generation energy affect the safe operation of the power grid

So far, the existing various power generation schemes that use solar energy as energy have high site requirements, large investment, and extremely low utilization rate of light. Solar energy in rural areas varies with the natural terrain and seasons of latitude and longitude, and to reduce the change in the intensity of light radiation, there is an urgent need to develop a small footprint, easy to arrange with changes in topography, and can effectively ensure the intensity of light radiation and stable power generation of photovoltaic power generation devices. Photovoltaic generators, while meeting the electricity demand of rural life / production and the needs of income generation, improve the efficiency of photovoltaic power generation and improve the utilization rate of light
