The invention relates to the technical field of water meters, and discloses a device for self power supply of a water meter; the device comprises a main pipeline, a side pipeline and a hydroelectric generation assembly. Two ends of the side pipeline are communicated with the main pipeline, and a water inlet of the side pipeline is provided with an electric control valve; the hydroelectric generation assembly is arranged in the side pipeline. According to the invention, the hydroelectric generation assembly can be driven to operate and generate electricity through flowing of water, so that power can be better supplied to the water meter through the hydroelectric generation assembly, the problem that water consumption is missed due to regular replacement of a battery is solved, and the water meter can operate efficiently and stably; after the opening degree of the electric control valve is controlled, the flow of water in main pipe into the side pipeline is controlled, so that the power generation efficiency of the hydroelectric power generation assembly is improved, the hydroelectric power generation assembly can provide sufficient power support for operation of the water meter, water consumption missing caused by regular replacement of a battery of the water meter is effectively avoided, and the metering accuracy of the water meter is improved. The invention further discloses a water meter using the device.
Description
technical field [0001] The present application relates to the technical field of water meters, for example, to a device for self-power supply of water meters and a water meter using the device. Background technique [0002] At present, most of the flow detection in the water meter field uses ultrasonic measurement, and the use of ultrasonic measurement of flow requires the transduction transmitter and transduction receiver to work in real time in order to continuously and accurately measure and accumulate water consumption. Once the meter is powered off, water leakage will occur. Therefore, the instrument powered by the built-in battery needs to be maintained by personnel who replace the battery in time. Even if the battery is replaced in time, it will cause leakage of metering during the battery replacement operation period. Therefore, the contradiction between the power consumption and power supply of the meter needs to be resolved. one of the key technologies. [0003] I...
