Description
本發明係有關於一種利用渦流動力發電的結構，尤指一種利用圓筒腔體創造渦流並使其加速的機構，並在圓筒腔體內使用通透性葉片組吸收渦流中的動能以發電的裝置。 The present invention relates to a structure that utilizes eddy current to generate electricity, especially a mechanism that utilizes a cylindrical cavity to create a vortex and accelerate it, and uses a transparent blade set in the cylindrical cavity to absorb the kinetic energy in the vortex to generate electricity. device.
按，現今大型風力發電的一般設計是採用水平軸三葉片渦輪的塔柱型構造，這種設計至少有下列缺點：(1)葉片結構精細，製造成本高昂；(2)葉片結構巨大，運輸困難；(3)葉片和發電機都在高處，裝設不易且維修不便；(4)機組重心在塔的頂端，靜態應力不穩定，且葉片的受力不平均，動態應力不穩定；(5)裸露的葉片及支架易在強風中受損；(6)風力太弱或太強都影響發電的效能；(7)風能利用率較低；(8)葉片旋轉時對飛行物造成危險；(9)低頻噪音干擾生態；(10)使用年限短；(11)難以更新；(12)難以回收。以上各項缺點都無法解決，因而有待研發改進者。 According to the current general design of large-scale wind power generation, the tower-type structure of the horizontal axis three-blade turbine is adopted. This design has at least the following disadvantages: (1) the blade structure is fine and the manufacturing cost is high; (2) the blade structure is huge and difficult to transport ; (3) The blades and generator are at high places, which is not easy to install and maintain; (4) The center of gravity of the unit is at the top of the tower, the static stress is unstable, and the force on the blades is uneven, and the dynamic stress is unstable; (5) ) Bare blades and brackets are easily damaged in strong winds; (6) Too weak or too strong wind will affect the efficiency of power generation; (7) The utilization rate of wind energy is low; (8) When the blades rotate, it will cause danger to flying objects; (9) Low-frequency noise disturbs the ecology; (10) The service life is short; (11) It is difficult to update; (12) It is difficult to recycle. None of the above shortcomings can be solved, so it needs to be developed and improved.
按，一般習用的大型水平軸風力發電機，其缺點在於：其葉片脆弱，高重心，構造複雜，製造困難，運輸困難，建造困難，保養困難，對鳥類產生危險，噪音，難以更新拆除及回收，綜合而言，其使用壽命短，成本極高。習用的垂直軸風車的缺點是：有脆弱的垂直軸及葉片，無法抵抗強風，故無法大型化。 According to the conventional large-scale horizontal axis wind turbine, its disadvantages are: its blades are fragile, high center of gravity, complex structure, difficult to manufacture, difficult to transport, difficult to construct, difficult to maintain, dangerous to birds, noise, difficult to update, dismantle and recycle , in general, its service life is short and the cost is extremely high. The disadvantage of the conventional vertical axis windmill is that it has a fragile vertical axis and blades, which cannot resist strong winds, so it cannot be enlarged.
本發明人已注意到US4452562A前案，該前案與本案明顯的差異如下： 前案的集風塔有內壁和外壁，兩壁之間有空間，集風塔的頂端完全敞開，底部與下方的進風室相通，進入方形進風室之氣流無法形成渦流，故氣流並不會如龍捲風般自動加速。本案的圓筒腔體為單層壁構造，頂端除中心部分外全被覆蓋，其底端並無開口及進風室，氣流係由圓筒腔體側面的複數個流體入口進入，再由頂端中心之流體出口排出，因而在圓筒腔體內形成類似於龍捲風的完整風場。 The inventor has noticed the previous case of US4452562A, and the obvious differences between the previous case and this case are as follows: The wind collecting tower of the previous case has an inner wall and an outer wall, and there is a space between the two walls. The top of the wind collecting tower is completely open, and the bottom is connected with the air inlet chamber below. The airflow entering the square air inlet chamber cannot form a vortex, so the airflow is not Does not automatically accelerate like a tornado. The cylindrical cavity in this case is a single-walled structure, the top end is completely covered except for the central part, and the bottom end has no opening or air inlet chamber. The fluid outlet in the center is discharged, thus forming a complete wind field similar to a tornado in the cylindrical cavity.
前案之渦輪及轉軸在集風塔與進風室之間，該渦輪之葉片並非為通透性的構造，故氣流只掠過葉片一次，葉片無法回饋動能使氣流再增速。 The turbine and the rotating shaft in the previous case are located between the wind collecting tower and the air inlet chamber. The blades of the turbine are not of a transparent structure, so the airflow only passes over the blades once, and the blades cannot give back kinetic energy to accelerate the airflow again.
本案複數通透性葉片及驅動軸都在圓筒腔體內部，沒有進風室，流入流體衝擊複數通透性葉片後，仍可維持其螺線形路徑並加速，如龍捲風一般的增強渦流。 In this case, the plurality of permeable blades and the drive shaft are all inside the cylindrical cavity, and there is no air inlet chamber. After the inflowing fluid hits the plurality of permeable blades, it can still maintain its spiral path and accelerate, enhancing the vortex like a tornado.
本發明人曾以CFD模擬本發明中圓筒腔體內的流體，結果證實：圓筒腔體內形成渦流，渦流的外圍流速較低，渦流的中心流速較高，渦流的外圍呈現高壓，渦流的中心呈現低壓，渦流的中心流向出口，以上六種特徵均與氣旋及龍捲風一致；根據以上原理，因而研發出創新的裝置以解決現存風力發電的所有問題。 The inventors used CFD to simulate the fluid in the cylindrical cavity of the present invention, and the results confirmed that a vortex is formed in the cylindrical cavity, the peripheral velocity of the vortex is low, the central velocity of the vortex is high, the periphery of the vortex presents high pressure, and the center of the vortex is high pressure. Showing low pressure, the center of the vortex flows to the outlet, the above six characteristics are consistent with cyclones and tornadoes; according to the above principles, innovative devices have been developed to solve all the problems of existing wind power generation.
