Description

寬風域微風發電系統Wide wind area breeze power generation system

本發明涉及風力發電技術領域，尤其涉及一種寬風域微風發電系統。The invention relates to the technical field of wind power generation, in particular to a wide wind area breeze power generation system.

伴隨著全球傳統能源的告急，世界各國越來越重視對各種可再生清潔能源的利用。風力發電沒有燃料問題，也不會產生輻射和環境汙染，取之不盡用之不竭。目前的風力發電技術已經相對成熟，利用風力吹動風葉旋轉，將風能轉化為機械能帶動發電裝置工作，從而產生可供利用的電能。當前，風力發電機組主流為水平軸風機，其具有單機容量較大、壽命較長等優點，但其對葉片的材料，強度要求較高，並且難以維修保護。由於水平軸風機大多採用雙饋發電機，其前端需要加入增速齒輪箱，使得齒輪箱的故障率較高，嚴重影響風機正常運行。水平軸風機的機艙高度因其容量大小而在幾十米到上百米不等，造成維護工作較為複雜且危險性較高。面對颱風、雷擊以及噪聲問題束手無策。風車式發電設備的發電效率以及對風能的利用率較低，並且對環境要求較高，需要較強的氣流，無法確定集風端始終對準強風方向。對於風力資源相對匱乏，並且風的來向不確定的環境，難以很好的完成發電任務。With the emergency of global traditional energy sources, countries around the world are paying more and more attention to the use of various renewable and clean energy sources. There is no fuel problem in wind power generation, nor will it produce radiation and environmental pollution. The current wind power generation technology is relatively mature, using wind to wind the blades to rotate, converting wind energy into mechanical energy to drive the power generation device to work, thereby generating available electrical energy. At present, the mainstream of wind turbines is horizontal-axis fans, which have the advantages of large single-machine capacity and long life, but their requirements on the material of the blades are high in strength and difficult to maintain and protect. Since most of the horizontal-axis fans use doubly-fed generators, a speed-increasing gear box needs to be added at the front end, which results in a higher failure rate of the gear box and seriously affects the normal operation of the fan. The height of the cabin of the horizontal-axis fan varies from tens of meters to hundreds of meters due to its capacity, resulting in more complicated and dangerous maintenance work. Faced with typhoons, lightning strikes and noise problems, they were helpless. Windmill-type power generation equipment has low power generation efficiency and low utilization rate of wind energy, and has high requirements on the environment. It requires strong airflow, and it cannot be determined that the wind collecting end is always aligned with the direction of strong wind. For an environment where wind resources are relatively scarce and the direction of wind is uncertain, it is difficult to complete the power generation task well.

本發明提供了一種寬風域微風發電系統，以解決統風力發電機安裝維護複雜難度高、危險系數高的問題。The invention provides a wide wind region breeze power generation system to solve the problems of high complexity and high risk factor for installation and maintenance of a unified wind power generator.

Although the drawings show exemplary embodiments of the present invention, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those of ordinary skill in the art.

如第1圖和第2圖 所示，本發明的實施例提供了一種寬風域微風發電系統，包 括：第一塔架1、第二塔架2、呈圓形的葉輪3和至少一個齒輪連軸發電機4。As shown in FIGS. 1 and 2, an embodiment of the present invention provides a wide wind region breeze power generation system, including: a first tower 1, a second tower 2, a round impeller 3, and at least one gear Coupling generator 4.

該實施例中，所述葉輪3的外緣均勻的安裝有齒輪31，當風能推動葉輪3繞中心軸旋轉時，齒輪31跟隨葉輪3轉動；所述齒輪連軸發電機4與齒輪31嚙合，因此在葉輪3轉動時，實現藉由齒輪31帶動齒輪連軸發電機4轉動， 將動能轉換為電能，最終實現風能轉化為電能。In this embodiment, a gear 31 is evenly mounted on the outer edge of the impeller 3, and when the wind energy pushes the impeller 3 to rotate around the central axis, the gear 31 rotates with the impeller 3; the gear coupling generator 4 meshes with the gear 31 Therefore, when the impeller 3 rotates, the gear 31 drives the gear coupling generator 4 to rotate, which converts the kinetic energy into electrical energy, and finally realizes the conversion of wind energy into electrical energy.

需要說明的是，所述齒輪連軸發電機4的數量可根據設計功率進行設置，並且設置多個齒輪連軸發電機4時，由於該多個齒輪連軸發電機4由同一齒輪帶動，可以保證齒輪連軸發電機4的轉速相同。It should be noted that the number of the gear coupling generators 4 can be set according to the design power, and when multiple gear coupling generators 4 are provided, since the gear coupling generators 4 are driven by the same gear, Ensure that the speed of the gear coupling generator 4 is the same.

此外，所述齒輪連軸發電機4設置在所述第一塔架1和所述第二塔架2上靠近地面的一端，並藉由機械結構傳動，保證發電系統維護工作可以在低空完成，大大降低了系統維護工作複雜程度、危險性和維護成本。並且風力發電機的低空安裝運行，可以對發電系統進行消聲降噪，還可以很好的完成對其的保護，避免了環境對風力發電機的侵蝕。In addition, the gear coupling generator 4 is disposed on the first tower 1 and the second tower 2 at the ends close to the ground, and is driven by a mechanical structure to ensure that the maintenance work of the power generation system can be completed at low altitude. Greatly reduces the complexity, danger and maintenance cost of system maintenance. In addition, the low-altitude installation and operation of the wind power generator can muffle the noise and reduce the noise of the power generation system, and can also well protect it, avoiding the environment from eroding the wind power generator.

其中，所述葉輪3包括：沿所述葉輪的徑向設置的多個葉片32以及與所述葉片32的末端連接的環形固定結構33；其中，所述齒輪31設置在所述環形固定結構33的外表面。Wherein, the impeller 3 includes: a plurality of blades 32 arranged along the radial direction of the impeller and an annular fixed structure 33 connected to the ends of the blades 32; wherein, the gear 31 is arranged on the annular fixed structure 33 Outer surface.

具體的，葉片32的末端為沿著葉輪3的徑向遠離葉輪3圓心的一端。環形固定結構33的圓心即為葉輪3的圓心，所述葉片32位於所述環形固定結構33的內部，並從所述圓心處沿著所述環形固定結構33的徑向呈放射狀分布。所述葉片32在第一方向上相對於所述環形固定結構33可旋轉；其中，所述第一方向與所述葉片32的延伸方向相垂直。較佳的，葉片32在第一方向上可旋 轉的角度範圍為 0~360°，以保證葉片32在第一方向上可以旋轉任意角度。Specifically, the tip of the blade 32 is the end away from the center of the impeller 3 along the radial direction of the impeller 3. The center of the ring-shaped fixed structure 33 is the center of the impeller 3. The blades 32 are located inside the ring-shaped fixed structure 33 and are radially distributed from the center of the ring along the radial direction of the ring-shaped fixed structure 33. The blade 32 is rotatable relative to the annular fixed structure 33 in a first direction; wherein, the first direction is perpendicular to the extending direction of the blade 32. Preferably, the angle range of the blade 32 in the first direction is 0~360°, to ensure that the blade 32 can rotate in any angle in the first direction.

這樣，藉由將葉片32在第一方向上旋轉至不同的角度，以調整葉片32的迎風面積，以保證在不同的風速情況下葉輪3能夠維持在一個穩定的轉速範圍內。In this way, by rotating the blade 32 to a different angle in the first direction, the windward area of the blade 32 is adjusted to ensure that the impeller 3 can maintain a stable speed range under different wind speeds.

需要說明的是，葉片32的數量可以根據設計功率進行設置，如第1圖中雖然給出了一種葉輪3具有5個葉片32的示例，但是本發明實施例還可以設置葉輪3具有除此之外的其他數量的葉片32，本發明不以此為限。It should be noted that the number of blades 32 can be set according to the design power. For example, although FIG. 1 shows an example in which the impeller 3 has five blades 32, the embodiment of the present invention may also set the impeller 3 to have the other The number of blades 32 other than the present invention is not limited thereto.

該實施例中，藉由環形固定結構33將葉片32的末端固定，大大增強了風葉32應對惡劣天氣的能力；藉由環形固定結構33固定的風葉32也有利於增大風葉的迎風面積，在低風速的情況下，可以捕捉到更高的風功率，更高效率 的利用風力資源。In this embodiment, the end of the blade 32 is fixed by the annular fixing structure 33, which greatly enhances the ability of the wind blade 32 to cope with bad weather; the wind blade 32 fixed by the annular fixing structure 33 is also helpful to increase the windward area of the wind blade.
