Description
本發明是有關於水平軸型的風力發電設備，特別是有關於在上風型的風力發電設備具備將機艙內的機器冷卻的功能的風力發電設備。 The present invention relates to a horizontal axis type wind power generation facility, and more particularly to a wind power generation facility in which an upwind type wind power generation facility has a function of cooling a machine in a nacelle.
水平軸型的風力發電設備，是在被設於其頂部的機艙內內裝有發電機和增速機等的機器。這些機器在發電時因為會產生熱，所以具備將風力發電設備所產生的熱冷卻用的冷卻系統。一般的冷卻系統，是由將外氣的風取入進行熱交換的冷卻器所構成，冷卻器是為了將外氣的風取入，被設在風力發電設備的外側。 The horizontal axis type wind power generation facility is a machine in which a generator, a speed increaser, and the like are installed in a nacelle provided at the top thereof. These machines have a cooling system for cooling the heat generated by the wind power generation equipment because heat is generated during power generation. A general cooling system is constituted by a cooler that takes in the air of the outside air and exchanges heat, and the cooler is provided outside the wind power generation facility in order to take in the wind of the outside air.
具備冷卻器的風力發電設備已知例如專利文獻1。在這些風力發電設備中為了由此冷卻器效率佳地冷卻，有需要將外部的風有效率地取入。特別是在上風側具有轉子旋轉面之下風型的風車的情況，機艙是位於下風，因為被設在妨害風的流動的方向，所，以將冷卻器從機艙突出地設置。 A wind power generation apparatus equipped with a cooler is known, for example, in Patent Document 1. In order to efficiently cool the cooler in these wind power generation apparatuses, it is necessary to efficiently take in external wind. In particular, in the case of a wind turbine having a wind type below the rotor rotating surface on the windward side, the nacelle is located in a downwind because it is disposed in a direction in which the wind is blocked, so that the cooler is protruded from the nacelle.
[專利文獻1]美國專利第7057303號公報 [Patent Document 1] U.S. Patent No. 7,075,303
現在被商用化的大型的水平型的風力發電設備，幾乎都是下風型。下風型，是在上風側具有轉子旋轉面。下風型的情況，機艙是位於下風，冷卻器是從機艙突出地設置而有效地迎接風。此情況，為了有效地迎接風，是將冷卻器設成由比機艙的上面或是側面更大幅地突出的形狀較佳。 Large horizontal wind power plants that are now commercialized are almost all downwind types. The downwind type has a rotor rotating surface on the windward side. In the case of the downwind type, the nacelle is located in the downwind, and the cooler is protruded from the nacelle to effectively greet the wind. In this case, in order to effectively greet the wind, it is preferable to set the cooler to have a shape that protrudes more than the upper surface or the side surface of the nacelle.
然而將冷卻器設成從機艙突出的形狀的話，有需要追加設置該部分的支撐構造。進一步對於機艙的風的受風面積會變大，作用的風負荷也因為伴隨其變大，而需要追加可耐其風負荷用的構造的補強。 However, if the cooler is provided in a shape protruding from the nacelle, there is a need to additionally provide a support structure for the portion. Further, the wind receiving area of the wind in the nacelle is increased, and the applied wind load is also required to be added to the structure for resisting the wind load.
從以上，本發明的目的是提供一種由簡便的構成就可以效率佳地冷卻的風力發電設備。 From the above, an object of the present invention is to provide a wind power generation apparatus which can be efficiently cooled by a simple configuration.
本發明的風力發電設備，是為了達成上述目的，是包含機艙的上風型的風力發電設備，該機艙的一方側是與由輪轂及葉片所構成的轉子連接，在另一方側迎接風，藉由塔被支撐，其特徵為：在機艙的另一方側前端部 分形成空洞部，在空洞部前端設置冷卻器，具備將通過冷卻器的風從空洞部的後流側排氣用的排氣口。 In order to achieve the above object, the wind power generation apparatus of the present invention is an upwind type wind power generation facility including a nacelle, wherein one side of the nacelle is connected to a rotor composed of a hub and a vane, and the other side is greeted by the wind.

以下，依據圖示的實施例說明本發明的風力 發電設備。又，在各圖中同一部分附加同一符號，省略重複的說明。 Hereinafter, the wind power of the present invention will be described in accordance with the illustrated embodiment. Power Equipment. In the drawings, the same portions are denoted by the same reference numerals, and the description thereof will not be repeated.
本發明，是如第1圖所示的外觀的上風型的風力發電設備。在上風型的風力發電設備中，由輪轂2及葉片1所構成的轉子3，是位於將機艙4支撐的塔5的下風側。機艙4前端的承受風的部分，是由屋簷部14及側面支撐部20及側面通風孔13所構成，被屋簷部14及側面支撐部20覆蓋的內部基本上是空洞。 The present invention is an upwind type wind power generation apparatus having an external appearance as shown in Fig. 1. In the upwind type wind power generation facility, the rotor 3 composed of the hub 2 and the blades 1 is located on the leeward side of the tower 5 that supports the nacelle 4. The wind-receiving portion of the front end of the nacelle 4 is composed of the eaves portion 14, the side support portion 20, and the side vent holes 13, and the inside covered by the eaves portion 14 and the side support portion 20 is substantially hollow.
因此來自上風的流入風W1，是從機艙4的前端流入朝下側作為排出風W2被排出，或是從機艙4的前端流入從側面通風孔13作為排出風W3被排出。 Therefore, the inflow wind W1 from the windward is discharged as the exhaust air W2 from the front end of the nacelle 4, or is discharged from the front end of the nacelle 4 as the exhaust air W3.
在本發明的實施例1中，在被屋簷部14及側面支撐部20包圍的空間設置冷卻器7。在第1圖中將在深度方向被設置的冷卻器7由虛線圖示。且在冷卻器7的下部具備翼片狀的支撐構件10(虛線)。因此，冷卻器7是藉由屋簷部14將上面支撐，藉由左右的側面支撐部20將兩側面支撐，藉由翼片狀的支撐構件10將下面支撐。藉由此構造，來自上風的流入風W1，是全部通過冷卻器7之後作為排出風W2、W3被排出。又翼片狀的支撐構件10，也具有將排出風W2、W3圓滑地導引至外部用的整流板的功能。 In the first embodiment of the present invention, the cooler 7 is provided in a space surrounded by the eaves portion 14 and the side support portion 20. The cooler 7 provided in the depth direction is illustrated by a broken line in Fig. 1 . Further, a fin-shaped support member 10 (broken line) is provided at a lower portion of the cooler 7. Therefore, the cooler 7 is supported by the eaves portion 14, and the both side faces are supported by the left and right side support portions 20, and the lower surface is supported by the flap-shaped support member 10. With this configuration, the inflow wind W1 from the wind is discharged through the cooler 7 as the exhaust air W2, W3. Further, the fin-shaped support member 10 also has a function of smoothly guiding the exhaust air W2, W3 to the outer rectifying plate.
第2圖，是顯示機艙前面的立體圖。但是在 此圖中為了使內部的空洞明顯，顯示將冷卻器7取下時的形狀。從此圖明顯可知內部空洞是形成排氣導管9。且在形成排氣導管9的各部中為了使風的流通良好而適宜地使角部形成R面。例如機艙的下面是形成R面8，從機艙傾斜面11連續地連接。 Figure 2 is a perspective view showing the front of the nacelle. But when In this figure, in order to make the internal cavity conspicuous, the shape when the cooler 7 is removed is displayed. It is apparent from this figure that the internal cavity is the exhaust duct 9. Further, in each portion where the exhaust duct 9 is formed, in order to make the flow of the wind good, the corner portion is appropriately formed into the R surface. For example, the lower surface of the nacelle is formed with an R-face 8 and is continuously connected from the nacelle inclined surface 11.
依據第2圖的構成可了解，來自外部的風， 不被導入機艙本體內部，可遮蔽機艙本體內的收納機器不受風W。由此可保護機艙本體內的收納機器不受包含鹽分的海風等。 According to the composition of Fig. 2, it can be understood that the wind from the outside, It is not introduced into the interior of the nacelle body, and the storage machine inside the nacelle can be shielded from the wind. This protects the storage machine in the nacelle body from sea breeze containing salt.
第3圖，是顯示在安裝了冷卻器7狀態下的 機艙前面的立體圖。冷卻器7是例如水冷的冷卻水箱，藉由通過冷卻水箱面的風使內部的液體(水)被冷卻。依據第3圖的話冷卻器7是形成於屋簷部14的內部，迎接藉由屋簷部14被誘導的風。 Figure 3 is a view showing the state in which the cooler 7 is installed. A perspective view of the front of the cabin. The cooler 7 is, for example, a water-cooled cooling water tank, and the internal liquid (water) is cooled by passing the wind on the surface of the water tank. According to Fig. 3, the cooler 7 is formed inside the eaves portion 14 to greet the wind induced by the eaves portion 14.
依據由第1圖、第2圖、第3圖說明的實施 例1的構成的話，機艙內部的機器冷卻用的冷卻器7是設在機艙的上風前面，且，利用機艙的下面的R面8排氣的導管9、及冷卻器7下的翼形狀的支撐10，是設在機艙。 此下面的R面8是從機艙的傾斜面11連續地連接地形成排氣導管，可將在冷卻器7受風的風效率佳地成為排氣W2。 According to the implementation described in Fig. 1, Fig. 2, and Fig. 3 In the configuration of the first embodiment, the cooler 7 for cooling the machine inside the nacelle is provided in front of the windward of the nacelle, and the duct 9 which is exhausted by the R surface 8 on the lower surface of the nacelle and the wing shape under the cooler 7 The support 10 is located in the cabin. The lower R surface 8 is an exhaust duct that is continuously connected from the inclined surface 11 of the nacelle, and the wind that receives wind in the cooler 7 can be efficiently made into the exhaust gas W2.
且藉由在側面設置通風孔13，並追加排氣 口，藉由排氣W3就可以提高排氣效果。且藉由在冷卻器7上風設置屋簷部14，就可提高將外部的風朝冷卻器吸引 的效果。 And by providing ventilation holes 13 on the side and adding exhaust The exhaust can be improved by exhausting W3. And by providing the eaves 14 on the wind of the cooler 7, the external wind can be attracted to the cooler. Effect.
在本發明中，藉由將受風面積及排氣面積設 成同程度，就可抑制流動的風的減速，可有效地排氣。側面的通風孔13，是藉由設在機艙的兩側面，因為對於來自前面的風對照地被排氣，所以可將作用於機艙的兩側面的風負荷抵消，可以防止負荷的不平衡。 In the present invention, by setting the wind receiving area and the exhaust area At the same level, the deceleration of the flowing wind can be suppressed, and the exhaust can be effectively performed. The side vents 13 are provided on both sides of the nacelle, and are exhausted against the wind from the front, so that the wind loads acting on both sides of the nacelle can be offset, and the load imbalance can be prevented.
依據本發明，因為可以將冷卻器7設在機艙 前面，所以可以減小對於機艙的受風面積，可以期待風負荷也削減。且因為只由機艙的支撐構造物就可以將冷卻器7的周圍4邊支撐，所以機艙可輕量化。藉此，機艙支撐的構造物的重量也可以減少。 According to the invention, the cooler 7 can be placed in the cabin In the front, it is possible to reduce the wind receiving area for the nacelle, and it is expected that the wind load will also be reduced. Moreover, since the surrounding sides of the cooler 7 can be supported only by the support structure of the nacelle, the nacelle can be lightweight. Thereby, the weight of the structure supported by the nacelle can also be reduced.
在第4圖，顯示本發明的風力發電設備的實施例2。在此，未設置實施例1的側面的通風孔13。側面的通風孔13因為不存在所以來自上風的流入風W1，是從機艙4的前端流入且直接朝下側作為排出風W2被排出。此情況時流入風W1也是全部通過冷卻器7。如此藉由將受風面積及排氣面積設成同程度，在實施例2，也可獲得與實施例1同樣的效果。 In Fig. 4, a second embodiment of the wind power generation apparatus of the present invention is shown. Here, the vent holes 13 of the side surface of the first embodiment are not provided. Since the vent hole 13 on the side surface does not exist, the inflow wind W1 from the upwind flows in from the front end of the nacelle 4 and is discharged as the exhaust air W2 directly toward the lower side. In this case, the inflow wind W1 also passes through the cooler 7 in its entirety. Thus, in the second embodiment, the same effects as in the first embodiment can be obtained by setting the wind receiving area and the exhaust area to the same level.
在第5圖，顯示本發明的風力發電設備的實施例3。在此例中將實施例1的上下關係逆轉配置。將屋 簷部14作為下側時來自上風的流入風W1，是從機艙4的前端流入且直接朝上側作為排出風W2被排出。在此情況下，藉由在上面設定R面的排氣導管，就可以效率地通氣，可獲得與實施例1同樣的效果。排出風W3是從側面被排氣的點是與實施例1相同。 In Fig. 5, a third embodiment of the wind power generation apparatus of the present invention is shown. In this example, the vertical relationship of Embodiment 1 is reversed. House The inflow wind W1 from the wind when the crotch portion 14 is the lower side flows in from the front end of the nacelle 4 and is discharged as the exhaust air W2 directly toward the upper side. In this case, by setting the R-side exhaust duct on the above, it is possible to ventilate efficiently, and the same effects as in the first embodiment can be obtained. The point at which the exhaust air W3 is exhausted from the side is the same as in the first embodiment.
又第5圖的情況時因為屋簷部14位於下，所 以將此表現為屋簷雖不適切，但是任一的情況皆具有作為將風的流動朝冷卻器7誘導的誘導部的功能，可發揮此功能者在本說明書中稱為屋簷部。 In the case of Fig. 5, because the eaves portion 14 is located below, In this case, it is not suitable for the eaves, but in any case, it has a function as an inducing portion that induces the flow of wind toward the cooler 7, and the person who can exhibit this function is referred to as an eaves portion in this specification.
在第6圖，顯示本發明的風力發電設備的實施例4。在此例中將實施例2(第4圖)的上下關係逆轉配置。將屋簷部14作為下側時來自上風的流入風W1，是從機艙4的前端流入且直接朝上側作為排出風W2被排出。此情況時也可獲得與實施例2同樣的效果。 In Fig. 6, a fourth embodiment of the wind power generation apparatus of the present invention is shown. In this example, the vertical relationship of Embodiment 2 (Fig. 4) is reversed. When the eaves portion 14 is the lower side, the inflow wind W1 from the wind is discharged from the front end of the nacelle 4 and directly discharged upward as the exhaust air W2. Also in this case, the same effects as in the second embodiment can be obtained.
在第7圖，顯示本發明的風力發電設備的實施例5。在此例中不具備屋簷部14。在實施例1至實施例4中，將由設在上或是下的屋簷部14流入的風導引，將風從機艙前端朝位於深入的位置中的冷卻器7接觸。在實施例5中，藉由將冷卻器7配置於機艙前端就可以效率地通氣，可以獲得與其他實施例同樣的效果。 In Fig. 7, a fifth embodiment of the wind power generation apparatus of the present invention is shown. In this example, the eaves portion 14 is not provided. In the first to fourth embodiments, the wind that flows in from the eaves portion 14 provided above or below is guided to contact the wind from the front end of the nacelle toward the cooler 7 located in the deep position. In the fifth embodiment, the cooler 7 can be efficiently ventilated by being disposed at the front end of the nacelle, and the same effects as those of the other embodiments can be obtained.
在第8圖，顯示本發明的風力發電設備的實施例6。第8圖，是第7圖的冷卻器7的機艙前端配置的情況時，不設置側面的通風孔13的事例。此例也可獲得與其他實施例同樣的效果。 In Fig. 8, a sixth embodiment of the wind power generation apparatus of the present invention is shown. Fig. 8 is a view showing an example in which the vent hole 13 of the side surface is not provided when the front end of the nacelle of the cooler 7 of Fig. 7 is disposed. This example can also obtain the same effects as the other embodiments.
又將實施例5、實施例6的構成上下反轉配置也可以。 Further, the configurations of the fifth embodiment and the sixth embodiment may be arranged upside down.
第9圖，是顯示機艙內部構成。在機艙內設有藉由轉子3的旋轉被驅動的增速機40及發電機50。又轉子3、增速機40、發電機50是藉由軸55被結合。 Figure 9 shows the internal structure of the cabin. A speed increaser 40 and a generator 50 that are driven by the rotation of the rotor 3 are provided in the nacelle. Further, the rotor 3, the speed increaser 40, and the generator 50 are coupled by a shaft 55.
其中增速機40是由齒輪所構成，其內部被油浸。油冷卻器41是與增速機40鄰接設置，來自冷卻器7的冷卻水42被供給，使藉由油冷卻器41內的熱交換被加熱的冷卻水43被排出。44是油冷卻器41內的熱交換配管，進行與增速機40連結的油冷卻器41內的與油的熱交換，將增速機40冷卻。 The speed increaser 40 is composed of a gear and the inside thereof is oil immersed. The oil cooler 41 is provided adjacent to the speed increaser 40, and the cooling water 42 from the cooler 7 is supplied, and the cooling water 43 heated by the heat exchange in the oil cooler 41 is discharged. Reference numeral 44 denotes a heat exchange pipe in the oil cooler 41, and performs heat exchange with oil in the oil cooler 41 connected to the speed increaser 40 to cool the speed increaser 40.
空氣冷卻器51也對於發電機50鄰接設置。例如被設在發電機50的上部的空氣冷卻器51，是將來自風扇52的風藉由冷卻水53冷卻後供給至發電機50內，將其內部冷卻。又風扇52是將發電機50內的空氣朝空氣冷卻器51送入。 The air cooler 51 is also disposed adjacent to the generator 50. For example, the air cooler 51 provided in the upper portion of the generator 50 cools the air from the fan 52 by the cooling water 53 and supplies it to the generator 50 to cool the inside. Further, the fan 52 feeds the air in the generator 50 toward the air cooler 51.
如以上，藉由油冷卻器41或是空氣冷卻器51中的熱交換被加熱的冷卻水53、54是朝冷卻水箱等的冷卻器7被送出並再度被冷卻，被循環供給。 As described above, the cooling waters 53, 54 heated by the heat exchange in the oil cooler 41 or the air cooler 51 are sent to the cooler 7 of the cooling water tank or the like and are cooled again, and are circulated and supplied.
依據以上說明的本發明的話，因為風車是上風型，所以機艙被設在上風側。藉由在機艙的前面設置冷卻器，將可以將受風的風效率佳地排氣的排氣導管設在機艙而成為可排氣。因此，沒有必要將冷卻器從機艙突出地設置，可設成組入機艙的形狀。由此，可以減小對於機艙的風的受風面積，可以期待風負荷也削減。伴隨其的支撐構造物的重量也可以減少。 According to the invention described above, since the windmill is of the upwind type, the nacelle is provided on the windward side. By providing a cooler in front of the nacelle, an exhaust duct that can efficiently exhaust the wind-driven wind can be installed in the nacelle to be exhausted. Therefore, it is not necessary to project the cooler from the nacelle, and it can be set into the shape of the nacelle. Thereby, the wind receiving area of the wind in the nacelle can be reduced, and the wind load can also be expected to be reduced. The weight of the support structure accompanying it can also be reduced.
