Description

一种垂直轴风力发电机与混凝土塔筒一体式结构 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与混凝土塔筒一体式结构。
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。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；另外，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。
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与混凝土塔筒一体式结构，能够节约基础的建造成本，更好的保护发电机。
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与混凝土塔筒一体式结构，包括位于地面上的上混凝土基础和位于地下的下混凝土基础，所述上混凝土基础与下混凝土基础之间的空间形成储能水池，塔筒的下端穿过上混凝土基础并固定在下混凝土基础上， 所述上混凝土基础与下混凝土基础之间设有支撑柱；所述上混凝土基础上设有供塔筒穿过的通孔，所述储能水池内设有安装平台，所述安装平台上设有发电机，所述塔筒上套有主齿轮，所述主齿轮驱动发电机，所述主齿轮设在储能水池内。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。
作为改进，所述安装平台上保护罩，保护罩与安装平台形成隔音室，所述发电机和主齿轮设在隔音室内。
作为改进，所述保护罩上设有水轮机，水轮机环抱塔筒而设。
作为改进，所述上混凝土基础上设有供塔筒穿过的通孔，塔筒外的鼠笼穿过通孔并分别与水轮机和主齿轮连接。
本实用新型与现有技术相比所带来的有益效果是：
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。
