Miniature water flow power generation device and intelligent water meter

Abstract

The invention relates to the technical field of water flow power generation, and provides a miniature water flow power generation device and an intelligent water meter applying the miniature water flow power generation device. The miniature water flow power generation device is characterized in that a miniature generator body and a magnetic transmission impeller are separately arranged on the outer side and the inner side of a water pipe, so a magnetic driving wheel on the input shaft of the miniature-generator body can be in magnetic transmission connection with the magnetic transmission impeller, so that the input shaft is prevented from being soaked in water for a long time, and the service life of the whole miniature-generator body is prolonged. Besides, the miniature generator body with low power is selected, power can be generated under the condition of micro water flow, water pressure loss is small, and the installation requirements of the intelligent water meter are met. And meanwhile, by arranging energy storage equipment and an energy management system, weak electric energy can be collected, and the electric energy collected by the energy storage equipment is subjected tooutput management through the energy management system, so that the charging requirement of an intelligent electric meter is met.

Description

technical field [0001] The present invention relates to the technical field of water flow power generation, and more specifically, to a miniature water flow power generation device and an intelligent water meter. Background technique [0002] In the existing technology, in order to facilitate the water supply unit to collect the water meter readings of the water terminal, smart water meters began to use a large number of wireless remote transmission methods to collect water meter readings. Due to the high battery consumption of the wireless remote transmission method, sometimes the structural circuit of the water meter is still under quality. The battery power has been exhausted within the year limit, and the battery needs to be replaced manually after the power is exhausted. This not only has high maintenance costs, but also causes inconvenience to users. [0003] At present, the above-mentioned problems are mainly solved by micro-current generators. The existing micro-cur...
