Abstract:
Water Intelligent Network (WIN) is being progressively adopted for better pipe leakage detection and water pressure management in urban water distribution systems. Traditionally, all the data monitoring meters and sensors of the WIN system are powered by chemical batteries, and the limited life and capacity of the battery makes it necessary to replace the battery frequently in the real?time monitoring mode, resulting in economic and manpower cost consumption. An inline hydropower harnessing device (IHHD) with the simple structure and convenient installation was developed. The IHHD only consumes a small part of the hydraulic head in water pipes to independently provide power to the sensing and monitoring equipment and data transmission devices of WIN, so that the frequency of data transmission to the master station can be greatly increased to facilitate real-time monitoring of the water supply network without frequent change of batteries. In addition, the blocks and bidirectional bell mouth design inside the inline turbine system make it capable of operating under bidirectional flows. This paper presents the working principle of the IHHD system and the results of the simulations and experiments of the development, as well as data gathered from site trial of the IHHDs inside live fresh water supply pipelines. The results demonstrate that the system can operate reliably as well as provide a valuable theory and utilization basis for the next stage research and development.
