风车抽水结合高山抽水蓄能电站的陆地风水混合发电系统
技术领域
本发明属于风—水发电领域，具体涉及一种风车抽水结合高山抽水蓄能电站的陆地风水混合发电系统。
背景技术
我国风能资源丰富，分布广泛，是一种清洁的可再生能源，风力发电是目前应用较为广泛的绿色发电技术，但由于风的间歇性和随机性等特点，风力发电往往具有波动性，导致发电量与电网需求不匹配。为了解决峰期用电紧张和谷期电能浪费的问题，储能设备应运而生。目前广泛使用的抽水蓄能电站是将储量丰富的水资源作为储能电源，电力负荷低谷期时，水从下水库抽到上水库蓄能，电力负荷高峰期时，水从上水库放至下水库发电，由此循环往复，有效错开峰谷期。
目前，风力和水力结合的发电装置，一般利用风力发电机提供电能给往复泵，将水抽至高处的水库，再由水力发电机发电，这种方式的缺点是风力发电机的输出功率不稳定，需要额外的电能供给水泵抽水。
发明内容
本发明要解决的技术问题是，克服现有技术中的不足，提供一种风车抽水结合高山抽水蓄能电站的陆地风水混合发电系统。
为解决上述技术问题，本发明采用的解决方案是：
提供一种风车抽水结合高山抽水蓄能电站的陆地风水混合发电系统，包括蓄能发电系统，还包括风力机械抽水系统；
蓄能发电系统包括排水管，其一端接至位于山顶的上蓄水水库，另一端接至位于山谷的下蓄水水库；在排水管上设置水轮发电机；
风力机械抽水系统包括两端分别连接上蓄水水库和下蓄水水库的抽水管，以及沿抽水管呈间距布置的多组风力机械抽水装置；每组风力机械抽水装置中均包括一个塔架，在其顶端设风车，在其底部设抽水泵；风车的叶轮中心固定在转轴端部，转轴安装在设于塔架顶端的旋转座内；转轴上还设有变速器，变速器的输出端连接传动轮，传动轮通过传动部件连接至抽水泵。
作为一种改进，变速器的传动比为1∶2～1∶4。
作为一种改进，相邻两组风力机械抽水装置的间距为20～30米。
作为一种改进，抽水泵是往复泵或离心泵。
作为一种改进，传动部件包括直角弯头和连杆；在传动轮上设有偏心轴孔，偏心轴孔通过直角弯头与连杆的顶端相连，连杆的底端与抽水泵相连，用于带动抽水泵运行。
作为一种改进，连杆设于塔架内部。
作为一种改进，水轮发电机是多组并列运行的水轮发电机，或者是多组串联运行的水轮发电机。
与现有技术相比，本发明的技术效果是：
本发明利用风车，将高山上丰富的风能转换为风车叶片的机械能，进而驱动往复泵抽取下蓄水水库水至上蓄水水库，机械能转化为势能，水向下排时再驱动水力发电机发电，势能转化为电能,提高了能源利用效率。
附图说明
图1为本发明的结构示意图。
图中各标号为：1-上蓄水水库，2-下蓄水水库，3-水轮发电机，4-排水管，5-抽水管，6-抽水泵，7-塔架，8-连杆，9-旋转座，10-传动轮，11-变速器，12-转轴，13-连接轴，14-叶轮。
具体实施方式
下面结合图1，对本发明的具体实施方式进行详细描述。
一种风车抽水结合高山抽水蓄能电站的陆地风水混合发电系统，包括蓄能发电系统，还包括风力机械抽水系统。
蓄能发电系统包括排水管4，其一端接至位于山顶的上蓄水水库1，另一端接至位于山谷的下蓄水水库2。在排水管4上设置水轮发电机3。水轮发电机3是多组并列运行的水轮发电机3，或者是多组串联运行的水轮发电机3。
风力机械抽水系统包括两端分别连接上蓄水水库1和下蓄水水库2的抽水管5，以及沿抽水管5呈间距布置的多组风力机械抽水装置，相邻两组风力机械抽水装置的间距为20～30米。本实施例中为20米。
每组风力机械抽水装置中均包括一个塔架7，在其顶端设风车，在其底部设抽水泵6。风车的叶轮14中心固定在转轴12端部，转轴12安装在设于塔架7顶端的旋转座9内。转轴12上还设有传动比为1∶2～1∶4的变速器11，本实施例中为1∶4，变速器11的输出端通过连接轴13连接传动轮10，传动轮10通过传动部件连接至抽水泵6。抽水泵6是往复泵或离心泵。
传动部件包括直角弯头和连杆8。在传动轮10上设有偏心轴孔，偏心轴孔通过直角弯头与设于塔架7内部的连杆8的顶端相连，连杆8的底端与抽水泵6相连，用于带动抽水泵6运行。
本发明共有两种工作状态：抽水蓄能和放水发电状态。
如图所示，当此装置处于抽水蓄能状态时，风吹叶轮14带动转轴12转动，通过变速器11提高转速后，连接轴13通过传动轮10和直角弯头带动连杆8活动，从而驱动抽水泵6工作，水流从下蓄水水库2抽至上蓄水水库1储存。当此装置处于放水发电状态时，蓄水库经排水管4向下放水，驱动水轮发电机3发电，尾水流至下蓄水水库2，根据电力峰谷期，不断调整此抽水蓄能发电装置所处状态，从而满足用电需求。
最后需要注意的是，以上列举的仅是本发明的具体实施例。显然，本发明不限于以上实施例，还可有很多变形。本领域的普通技术人员能从本发明公开的内容中直接导出或联想到的所有变形，均应认为是本发明的保护范围。
