The invention discloses an impeller pipeline power generation device, which is arranged on a pipeline. The power generation device is composed of a shell, an impeller unit and a generator set. The two ends of the shell adopt a conical structure with decreasing cross sections from outside to inside in order to increase the incoming flow velocity. The two ends of the shell are provided with flanges connected with the pipeline and are waterproof sealed through an apron, and the top of the shell is provided with a circular pipeline. The impeller unit consists of a shroud, impeller, spindle and coupling. The shroud is located in the inner shell under the circular pipe and welded with the inner wall of the shell. The bottom of the inner shell is provided with bearings, the impeller is fixed on the bearing, and the rotor of the impeller is connected with the spindle through the coupling. The generator unit includes a generator, a bracket and a waterproof sealing bearing, and the waterproof sealing bearing is arranged on the circular pipe. The main shaft passes through its inner hole, the top of the main shaft is connected with the rotor of the generator, and the stator of the generator is connected with the outer shell through the bracket. The device can make power generation daily and solve some of the daily electricity demand.

一种叶轮管道发电装置
本专利技术涉及水力发电领域,具体涉及在低水位差地带放置的一种叶轮管道发电装置。
技术介绍
目前,水力发电已经是一项很重要的发电方式。水力发电是利用河流、湖泊等位于高处具有势能的水流至低处,将其中所含势能转换成水轮机之动能,再借水轮机为原动力,推动发电机产生电能。一般水力发电机需要建在水位差较大的地方,而对于平原地带的小河上修建的小型水力发电站来说,发出的电压较小,可用性不强。我国小型水力发电资源非常丰富,据初步调查,理论蕴藏量有15亿kW,可开发的资源为7000万kW。再加上微水电,仅0.1~10kW的微水电蕴藏量就有8000万kW,其开发率为0.27%,只有小型水力发电开发率的1%。由此可以看出装机容量小于500kW的微水电开发潜力巨大。例如在一些平原地区的乡村用电和田间用电或者是偏远山区无电用户,他们的居住地远离人类聚集地并且往往很分散,在电力的输送过程当中会造成极大的电力资源损失。但是这些居住地附近常常会出现小的河流或者是人工开凿出来的水渠,这当中蕴藏着极为丰富的微小型水能资源。如果有一种发电装置可以利用水渠或者乡间的小河中平缓的水流来 ...
