Description

一种垂直轴风力发电机储水塔筒 技术领域
本实用新型涉及风力发电机，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。
发明内容
本实用新型所要解决的技术问题是提供一种垂直轴风力发电机储水塔筒，能够加强塔筒的强度。
为解决上述技术问题，本实用新型的技术方案是：一种垂直轴风力发电机储水塔筒，包括混凝土筒体和设在混凝土筒体底部的混凝土基础，所述混凝土筒体内部为中空结构，并在混凝土筒体内部形成储水腔体和电梯井，所述储水腔体由钢筒体包围。本实用新型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。
作为改进，所述电梯井的壁面设有供吊笼升降滑行的导轨。
作为改进，所述混凝土筒体内设有隔墙，所述隔墙与混凝体筒体的第一内壁面围成储水腔体，所述隔墙与混凝体筒体的第二内壁面围成电梯井。
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。
作为改进，所述隔墙包括相互贴紧的钢板和混凝土墙，所述钢板与贴紧第一内壁面的钢板形成钢筒体，所述混凝土墙与第二内壁面围成电梯井。
作为改进，所述混凝土墙与混凝土筒体一体灌注成型。
作为改进，第二内壁面设有钢板，第二内壁面的钢板与作为隔墙的钢板共同围成电梯井。
作为改进，所述混凝土筒体上设有连通电梯井的检修口。
本实用新型与现有技术相比所带来的有益效果是：
本实用新型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。
