Prepaid intelligent water meter based on water body self-flowing power supply

Abstract

The invention relates to the technical field of fluid metering apparatuses, in particular o a prepaid intelligent water meter based on water body self-flowing power supply. The internal part of a housing is divided into four small chambers, wherein a left upper chamber is a radio-frequency intelligent display chamber in which a radio-frequency control device a rechargeable battery, a liquid crystal display screen, a non-contact radio-frequency sensor and a data processing device are arranged; a right upper chamber is a number wheel counting chamber, a left lower chamber is a water turbine and control valve chamber, a power generator is arranged in a space, close to a water turbine in the left lower chamber, of the left upper chamber, a water isolating layer plate is arranged between the water turbine and the power generator, a water turbine shaft is connected with a power generator shaft through a magnetic coupling, a right lower chamber is a water meter mechanism chamber, and the water turbine shaft and the power generator shaft are coaxially connected through the magnetic coupling. Kinetic energy produced by water during flowing is used to push the water turbine and drive the power generator to generate power to charge the rechargeable battery to supply power needed by the radio-frequency sensor, the data processing device, the liquid crystal display screen and the motor.

Description

technical field [0001] The invention relates to the technical field of fluid metering equipment, in particular to a prepaid smart water meter based on self-flowing water body power supply. Background technique [0002] In recent years, the development of IC card prepaid water meters is in the ascendant. In fact, it is a smart water meter with a new concept that integrates multiple functions such as automatic water supply, automatic metering, automatic charging, automatic control, and display alarms. It is a replacement product for traditional water meters. It is mainly composed of three parts: the sending base meter, the electric control circuit board and the electric valve. Its working principle is: using IC smart card as the carrier, bidirectionally transmits data between the management system and the smart water meter to realize the function of water supply management. The user pays a fee to the water supply company to purchase a card, and stores the pre-purchased water...

AI Technical Summary

Problems solved by technology

Through searching, a utility model patent technology of "Self-generated Smart Water Meter" with the patent number of 200320129205.7 was found. After investigation, it was found that although the patent proposed a technical solution for water current generation as its own power supply, after careful analysis, it was found that the patented water turbine and There are still problems with the coupling technology between the generators: "... there is an impeller built in the cavity, and the impeller shaft is lengthened so that the impeller shaft passes through the diaphragm upwards and is on the contact surface of the impeller shaft and the diaphragm Set seal"

It is not difficult to see from the above description that if the sealing ring leaks slightly, the entire water meter will be scrapped, so a major correction must be made to the self-generating water meter
