Description

Solar Focused Stirling Engine Power Plant

The invention relates to a solar focusing Stirling engine power generating device, which is applied to power generation and reuse of kinetic energy.

At present, the rapid changes in the earth's climate have brought serious disasters to the rest of the world, such as China, Vietnam, Japan, Indonesia, the Philippines, Australia or Europe, etc., which have caused severe floods and reduced a large amount of rain in a short period of time. The skyrocketing rivers and the flooding caused by rainwater flooding have seriously threatened the safety of people’s living. They also destroyed the planted or stored items. The reason is that although the reasons are not completely clear, there are still many people. It is believed that global warming is caused by the emission of carbon dioxide and other greenhouse gases into the Earth's atmosphere. These gases are like thick blankets that cover the heat of the sun, causing the temperature of the earth to rise. The more greenhouse gases, the more the earth's temperature will be. The higher the number, the more they advocate the issue of reducing carbon emissions. Under such circumstances, countries have advocated energy conservation and environmental protection issues to protect the earth from being destroyed. In order to save energy and save carbon, the biggest and cheapest are not used. The endless thing is the sun, how to turn the sun into a usable resource is the goal that everyone is currently chasing. For example, it has been about 20 years since the solar panel was placed at the light source. However, using solar panels to generate electricity, some people think that it still has problems of pollution and high cost, etc., for example, solar panels are manufactured from various ends. Damage from the manufacturing process to the final use will cause pollution problems. Since the large amount of electricity used in the manufacturing process and the overall cost are higher than other methods, advanced countries no longer encourage this development, in order to solve the greenhouse effect. The problem is that the current use of sunlight to focus on Stirling engine power generation is a relatively new topic. The inventor of this case, after working in the relevant field of this case, has been conceived for a considerable period of time, collecting information, summarizing, analyzing, composing, and finally completing. The creation of this case is mainly composed of a two-axis tracking mechanism, an arc focusing module, an energy storage and energy transfer system, and a Stirling engine. The arc-shaped focusing module receives light energy and focuses on the Stirling engine heating. Cover, so that the gas inside the cover is heated to change the pressure, forming a gas pressure difference in the chamber, triggering the Stirling engine piston shift In order to generate electricity or use kinetic energy for reuse, because such creations are almost non-polluting, they can be located in desert areas or wastelands that are not used, do not occupy space in areas with high use value, and can generate electricity without electricity, achieving energy saving and carbon saving. The big goal of saving the earth is really a good product of green energy.
