Description

一种垂直轴风力发电机储水塔筒 技术领域
本发明涉及垂直轴风力发电机，尤其是一种垂直轴风力发电机储水塔筒。
背景技术
目前，水力发电站的形式有如下几种：一是抽水蓄电站，将上游水库的水位势能输送到下游水库时水位所产生的动能经水力发电机转换成电能；二是有多数阶梯电站，也是有上下水库。风力发电目前都在直接并网发电，由于风力大小变化无常，带来所发的电能是无序劣质电能，风力发电具体应用具有很大的局限性。尽管上述二种都独立运行结构比较完善，但是不能与风能结合发电仍是可再生能源利用的一大遗憾。现有技术中有将风力发电设备与水力发电设备联合发电的，如中国专利公开号为102748195的一种风力水力混合发电装置，包括有上水库、低于上水库的下水库、联通上下水库之间的输水管及安装在输水管上的水力发电装置，在上水库的一侧设置有风力发电装置，风力发电装置发出的电通过输电线路输入给变频电动机，变频电动机带动抽水泵抽水，抽水泵的进水口通过输水管与下水库内的底部联通、出水口通过输水管与联通上下水库之间的输水管联通，变风力发电的无序劣质电源为电网用电高峰时需要的优质电源，变频电机适用于风力发电机或风力发电机组发出波动电源，充分地利用了可再生能源中的风能，可优化电网结构，加大电网削峰填谷能力，有效降低运行总成本，适用于中小型水力 发电站。该种风力水力发电设备虽然能够关联发电，但是二者融合度不高，也就是说从结构上看，风力发电设备与水力发电设备彼此相互独立，其存在的缺陷在于：水库占地面积大，占用大量的土地资源；风力发电机需要建设在水库附件，受到地域的限制，不利于风力发电设备有效利用风力资源；另外，在风力发电机的基础上，若需要建造蓄水池，则需要选择有地势高的地方，这样才能依靠水的重力推动水力发电，这样一来，蓄水池的建造同样受到地域的限制。
为了改变目前蓄水池占地问题，现有出现一种塔筒集成储水的垂直轴风力发电机，如中国专利公开号为CN 108953039A的一体式垂直轴风力发电与高空储水蓄能发电系统，包括风力发电装置和水力发电装置，风力发电装置包括混凝土塔筒、风力发电机和设在混凝土塔筒上且用于驱动风力发电机的风轮；水力发电装置包括高位蓄水池、低位蓄水池、抽水设备和水力发电机，混凝土塔筒为中空结构，其内部封闭的容置腔体形成所述高位蓄水池。塔筒内部储水，因此塔筒受到的压力增大，目前的混凝土塔筒能承受的压力有限，需要进一步提交塔筒的强度。另外，该蓄水池围绕塔筒基础建造，二者分开建造，建造的工期相对较长，而且建造所用的材料也较多，导致最终建造成本增加；而且发电机和水轮机安装在地面上，受到的干扰更多，而且噪音也大。

本发明混凝土筒体具有强度高，耐腐蚀的特性，再配合混凝土筒体内部的钢筒体，进一步提升塔筒的强度，使塔筒能够储备大量水。塔筒的混凝土基础与储能水池一体建造成型，储能水池作为塔筒基础的一部分，可以节约塔筒基础的建造成本；另外，发电机埋设在地面下，受外界的干扰更小，而且发出的噪音也更小。桁架式转轴中，利用倾斜加强梁与纵梁主城内的三角形结构，三角形结构具有稳定性，使桁架式转轴结构稳定，不易变形。
作为改进，所述隔墙为钢板，所述钢板与贴紧第一内壁面的钢板形成钢筒体。

所述混凝土筒体11内设有隔墙，所述隔墙与混凝体筒体的第一内壁面围成储水腔体13，所述隔墙与混凝体筒体的第二内壁面围成电梯井16。本实用新型的隔墙有多种形式：
如图2所示，第一种：所述隔墙为第一钢板14，所述第一钢板14与贴紧第一内壁面的第二钢板12形成钢筒体，钢筒体内形成储水腔体13，第一钢板14与第二内壁面共同围成电梯井16。
如图3所示，第二种：所述隔墙包括相互贴紧的第一钢板14和混凝土墙17，所述第一钢板14与贴紧第一内壁面的第二钢板12形成钢筒体，所述混凝土墙17与第二内壁面围成电梯井16，所述混凝土墙17与混凝土筒体11一体灌注成型。

如图5所示，所述混凝土基础2包括位于地面上的上混凝土基础22和位于地下的下混凝土基础23，所述上混凝土基础22与下混凝土基础23之间的空间形成储能水池26，塔筒1的下端穿过上混凝土基础22并固定在下混凝土基础23上，所述上混凝土基础22与下混凝土基础23之间设有支撑柱25，上混凝土基础22、下 混凝土基础23、支撑柱25和混凝土塔筒1形成一体化结构，塔筒1的混凝土基础与储能水池26一体建造成型，储能水池26作为塔筒1基础的一部分，可以节约塔筒基础的建造成本。
如图6所示，所述储能水池26内设有安装平台24，所述安装平台24为混凝土平台，安装平台24位于储能水池26的上部，安装平台24由支撑柱25支撑，塔筒1穿过安装平台24。所述安装平台上设有发电机，所述塔筒1上套有主齿轮21，所述主齿轮21驱动发电机，所述主齿轮21设在储能水池内；所述安装平台上保护罩28，保护罩28与安装平台24形成隔音室，所述发电机和主齿轮21设在隔音室内；该安装平台24可以用于固定发电机等设备，从而将发电设备设在地下，减少发电机的噪音，而且对发电机等设备更好的保护。保护罩28的顶部设有环抱塔筒1而设的水轮机29。所述上混凝土基础22上设有供塔筒1穿过的通孔27，套在塔筒1外壁上的桁架式转轴3通过通孔27进入地下的储能水池26中并与水轮机29和主齿轮21联动。塔筒1中的储存的水在重力作用下推动水轮机29，与水轮机29能量交换后的水直接流回储能水池26
中，并通过水泵再次抽送至塔筒1内。
如图7、8所示，所述桁架式转轴3包括若干呈圆周均匀分布的纵梁311，相邻纵梁311组成一个加强框架31，所有加强框架31相连组成多面体，多面体围成的内部空腔，塔筒1设在内部空腔内，从而整个桁架式转轴结构能够围绕塔筒1旋转。加强框架31中设有若干首尾相连的倾斜加强梁312，所述倾斜加强梁312的两端分别与两侧的纵梁311相连，相邻的两根倾斜加强梁312与纵梁311组成三角形结构，相邻倾斜加强梁12之间的夹角为45°、60°、90°、120°或135°，本实施例选用60度，所以三角形结构为等边三角形结构，其稳定性更好。相邻纵梁311之间设有横向 加强梁313，横向加强梁313的两端分别与两侧的纵梁311连接，横向加强梁313位于相邻两根倾斜加强梁312之间。所述纵梁311、倾斜加强梁312、横向加强梁313均为钢管件或槽钢。所述倾斜加强梁312、横向加强梁313和纵梁311之间采用连接件连接，且连接件与各部件的连接均为螺栓连接。桁架式转轴中，利用倾斜加强梁312与纵梁311主城内的三角形结构，三角形结构具有稳定性，使桁架式转轴结构稳定，不易变形。
