Card-plugged water meter self-charging device

Abstract

The invention relates to a card-plugged water meter self-charging device. A high-grade charging water meter on the current market adopts an electronic charging method, belonging to a prepayment manner, can be used after being purchased and paid in advance, has the problem that battery life is short as environment is moist and charging can not be carried out and is not applicable to a humid environment owning to a 220V power supply. Aiming at solving the application problem of a new high-grade water meter, a circular side waterway card-plugged water meter self-charging device is designed, hydraulic pressure and impulsive force during operation are used for generating, and a battery is charged after current and voltage are processed, thus life of a rechargeable battery is prolonged, the defect that the battery is frequently replaced is reduced, the problem that normal use is influenced is solved, and technical assurance is provided for popularization of the high-grade water meter. The card-plugged water meter self-charging device is characterized in that the card-plugged water meter self-charging device body is provided with a water inlet, the self-charging device body is internally provided with an impeller and a microgenerator, and the impeller and the output terminal of the microgenerator are connected onto a water meter battery. The card-plugged water meter self-charging device provided by the invention has the advantages that no additional power supply is used, the impulsive force of water flow is used for generating, sealing is disposable, and the card-plugged water meter self-charging device is resistant to moisture and vibration.

Description

1. Technical field: [0001] The invention relates to a self-charging device for a card-inserted water meter. 2. Background technology: [0002] At present, the advanced billing water meters on the market adopt the electronic billing method, which belongs to the prepaid method, and must be purchased and paid in advance before they can be used. Now there is a problem of short battery life. The reason is that the environment is humid and cannot be charged, especially the 220 power supply is not suitable for a humid environment. In order to solve the application problem of the new advanced water meter, we have designed a self-charging device for the water meter with a circular side channel plug-in card. , use the water pressure impulse power generation during use, after the current and voltage are processed, charge the battery, prolong the life of the rechargeable battery, reduce the shortcomings of frequent battery replacement, and affect the normal use of the disadvantages, a...
