We are responsible for providing energy and food resources for our next generation.After more than 20 years of research,the author has confirmed that the VAWT with flip-up mechanism can maintain rotation without the brake,even in strong winds.Experiments have shown that the triangularly coupled movable parallelogram buoyancy structure makes it easy to maintain the verticality of the wind turbine tower even under large waves.Furthermore,as a result of studying the connection between the HAWT(horizontal axis wind turbine)and the movable parallelogram buoyancy structure of the triangular connection,the feasibility was confirmed.The only way for all people in the world to secure energy and food fairly is to look for the remaining areas such as the high seas.The author would like to propose the use of the high seas to combat global hunger,which is likely to be a global problem in the future. 展开更多

In view of the movable hook structure on zero position,the traditional system could not recognize the zero scale.According to the essential requirements of the measurement,a new system based on machine vision was proposed.Standard datum planes and standard scales were designed as standard component,and the indication error can be calculated by comparing the standard component and the measured value between zero position and 500 mm scale.The alignment of scribed lines was realized by machine vision,and the float pixel equivalent method was applied in image process.Experimental results prove that this system meets the requirement of national standard steel tape verification regulation,and the repeatability of zero error can reach 0.006 mm after zero calibration. 展开更多
