Abstract

The invention provides a self-powered flow detection apparatus which comprises a main pipe, and a generator in the cavity of the main pipe, wherein the generator is connected with a current signal acquisition and processing apparatus and an electricity acquisition and storage apparatus. The current signal acquisition and processing apparatus acquires current signals of the generator and outputs the current signals which are converted into water flow information, and the electricity acquisition and storage apparatus acquires and stores electricity of the generator to realize self-powering. No externally connected power supply is required. The self-powered flow detection apparatus overcomes the difficulty in application of flow acquisition monitor and intelligent telemetering equipment due to inconvenient power supply. Current signals of the generator are directly converted into water flow information, and no intelligent water meter, or other high-precision devices are required, thereby substantially reducing cost. The self-powered flow detection apparatus is unlikely to be damaged, stable in performance, and simple in structure, and totally solves the problem of scattered installation of flowmeters and power supply difficulty. The self-powered flow detection apparatus monitors water resource under the Internet-of-things conditions, and water leakage of a pipe network can be timely discovered and treated. The self-powered flow detection apparatus is very important.
