Water meter self-generating power supply device

Abstract

The present invention discloses a water meter self-generating power supply device. The device comprises a box body, a water inlet pipe is inserted into the outer wall of the top of the box body, the box body is inserted into one end of the water inlet pipe, a connecting pipe is inserted into the outer wall of the bottom of the box body, a water guide pipe is inserted into one end of the connecting pipe, and a water meter body is inserted into the outer wall of the bottom of the water guide pipe; a first wire is arranged on the outer wall of the bottom of the box body, the end, away from the box body, of the first wire is communicated with the water meter body, sealing shells are fixedly connected to the inner walls of the two sides of the box body, and power supply assemblies for supplying power to the water meter body are arranged in the sealing shells. Self-sufficiency of electric power in the water meter can be achieved, the energy-saving requirement of people is met, uninterrupted power supply can be conducted on the water meter body, the problem that the service life of an existing water meter body is short due to a battery is solved, and meanwhile later replacement and maintenance work is reduced.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to a water meter self-generating power supply device. Background technique [0002] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. Water meters are installed in the water pipes of the water supply network to measure water consumption. In order to facilitate the water supply unit to collect the water meter readings of the water terminal, smart water meters are used in the prior art. Smart water meters need power supply to operate. [0003] At present, most smart water meters are powered by batteries. After the power is used up, the battery needs to be replaced manually. Sometimes the structural circuit of the water meter is still within the quality period, but the battery power is exhausted. This is not only costly, but also cons...

Problems solved by technology

[0003] At present, most smart water meters are powered by batteries. After the power is used up, the batteries need to be replaced manually. Sometimes the structural circuit of the water meter is still within the quality period, but the battery power is exhausted. This is not only costly, but also consumes manpower and material resources. The data measured by the water meter produces a large error, which brings great inconvenience to the user
