Low-power-consumption power-saving electronic water meter

Abstract

The invention discloses a low-power-consumption power-saving electronic water meter including a shell; the bottom in the shell is fixedly connected with the motor base; the motor base top is fixedly connected with the motor bottom; the motor is in interference fit with the cooling fan; an isolation net is arranged in the shell close to the top of the cooling fan; the separation net is fixedly connected with the shell inner wall; a water meter bottom hemispheroid is arranged in the shell close to the top of the separation net; two sides of the top of the water meter bottom hemispheroid are fixedly connected with a water inlet pipe and a water outlet pipe; a first sealing ring and a second sealing ring are in interference fit with the other ends of the water inlet pipe and the water outlet pipe; according to the invention, the low-power-consumption power-saving electronic water meter is provided with the power fan, the generator and the power supply; the power fan is driven to rotate through back-and-forth water flow power of the water inlet pipe and the water outlet pipe, so that the rotating rod is driven to rotate, the water flow power is finally converted into electric energy through the generator, the electric energy is stored in the power supply, dependence on an external power supply can be thoroughly eliminated, and the power-saving purpose is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of electronic water meters, in particular to an electronic water meter with low power consumption and power saving. Background technique [0002] Water meters are instruments for measuring water flow. They are generally divided into two types: volumetric water meters and speed-type water meters. Volumetric water meters are more accurate than speed-type water meters, but they have high requirements for water quality. When the water contains impurities, it is easy to be blocked; water meters are mainly A meter used to record the water consumption of tap water. The traditional mechanical water meter is installed on the water pipe. When the user releases water, the pointer or character wheel on the meter rotates to indicate the flow of water passing through. Existing rotor-type mechanical counting water meters all have a disadvantage, that is, reading the meter is convenient and not intuitive, and pointer-type w...

AI Technical Summary

Problems solved by technology

The existing rotor-type mechanical counting water meters have a disadvantage, that is, the reading part is convenient and not intuitive, and the pointer-type water meters have the phenomenon of pointer misalignment, which will cause misreading values

Although the direct-reading type has its own advantages, there are also cases where half a word appears when the word is skipped. After the surface of the mechanical water meter is rusted or misted, the measurement display is not clear, causing reading problems for the meter reader. With the continuous development of electronic technology, engineers have developed an electronic water meter to solve the problems of the above-mentioned traditional mechanical water meter.

[0003] Existing electronic water meters use external power sources as power sources, but the water flow power transmitted by the water pipes of the water meters cannot be effectively utilized, so a similar electronic water meter was invented
