摘要

本文主要為一種風電水循環機系統設計與開發，經由風能、微氣泡產生器（micro-bubble generator）及發電機結合，利用風能取代電能直接轉換成機械能，來進行抽水，再利用微氣泡產生器產生負壓吸取外部空氣與水混合，形成微氣泡增氧。藉由綠能轉換來輔助養殖場提高效率，以達到減少曝氧機能源的使用與耗損為目的。在風力機動力傳輸過程中，會藉由風力機時規皮帶輪組，將抽水泵浦增速至5倍，藉高速旋轉獲得的動能將水抽至微氣泡產生器，隨著高速的水流經由文氏管產生負壓吸入外部空氣，藉此產生大量的微氣泡，使水池增加空氣含氧量。在設計方面，首先利用3D列印技術，將不同形態風力機葉輪與微氣泡產生器及發電機結合，經由測試比較後，再垂直整合製作實體複合材料風力機葉輪，形成風電水循環機系統。在理論分析及量測方面，利用葉片元素動量法（BEM）模擬計算風機葉輪軸向阻升推力、扭力矩、機械能功率、風能功率、水能功率及電能功率。性能測量實驗方面，利用鼓風機模擬風場，配合不同的抽水泵浦型態及不同大小的水管進行測試，以此來量測風電水循環機轉速對於水流量、扭力、發電及各項功率之間的數據關係。

This paper mainly concerns the design and development of a composite wind power water cycle machine system, in which, through the combination of the wind energy, micro-bubble generator and power generator, it is possible to utilize wind energy, rather than electric energy, to directly convert into mechanical energy for pumping water, and then the micro-bubble generator can be utilized to generate negative pressure in order to absorb external air and water thereby forming micro-bubbles to increase oxygen. In this way, the green energy conversion may assist aqua-cultural farms to improve production efficiency thereby successfully reducing the use and waste of the aerator energy. Herein, during the wind turbine power transmissions, the speed of the water pump can be increased by 5 times via the wind turbine timing pulley set, and the kinetic energy obtained from the high-speed rotation is used to pump the water to the micro-bubble generator; following this, the high-speed water flows through the Venturi tube to generate a negative pressure thereby sucking in the outside air, so a large amount of micro-bubbles can be generated in order to increase the oxygen content of the pool. Moreover, in terms of design, the 3D printing technology is firstly used to combine different shapes of wind turbine impellers with micro-bubble generators and power generator; subsequently, after tests and comparisons, the composite wind turbine impeller can be vertically and integrally manufactured thus forming the wind power water cycle machine system. Furthermore, in theoretical analyses and measurements, the Blade Element Momentum (BEM) method can be used to simulate the axial resistance force, torque, mechanical energy, wind power, water power and electric power of the wind turbine impeller. Also, regarding to performance measurement experiments, the airflow field can be simulated by a blower, and different water pump types and water pipes of various sizes may be selected for testing in order to measure the data correspondence between the rotation speeds of the wind power water cycle machine with respect to water flow, torque, power generation and various power values.
