High-sensitivity photoelectric direct-reading remote water meter

Abstract

A high-sensitivity photoelectric direct-reading remote water meter having good metering accuracy and assembly convenience and capable of meeting IP68 protection level is provided. The High-sensitivityphotoelectric direct-reading remote water meter is characterized in that a module sealing box is arranged on a gear unit of the meter, the module sealing box and a housing inner chamber form a sealedchamber that can prevent outward leakage of water, the gear unit is pacakaged in the sealed chamber, and a wet lower gear, at the transmission end and less than a blade wheel in speed, in the gear unit is in synchronous rotation with a dry upper gear in the module sealing box in different pole opposing manner; the meter herein is a photoelectric direct-reading water meter having electricity and machine separation, the module sealing box divides a housing into a wet zone and a dry zone hermetically isolated, the direct gear engagement transmission structure, in the wet water met, having good transmission stability, precise transmission ratio, high metering sensitivity and good operating reliability is retained, and the high waterproof level of a dry water meter is also retained; counting numbers correct to three decimal places are digitally displayed in direct-reading manner, and the meter is suitable for real-time metering and monitoring in the internet of things.

Description

technical field [0001] The invention relates to a rotary-wing water meter, in particular to a high-sensitivity rotary-wing water meter which can directly read the water consumption and send the water consumption to a remote place with digital signals. Background technique [0002] Rotor-type water meters are divided into wet water meters or dry water meters according to whether the cumulative counter (also called counting wheel set 9) used for measurement is placed in water or not placed in water. [0003] 1. The wet water meter drives the accumulative counter in the following ways: [0004] The impeller arranged in the water meter case drives the central gear arranged on the tray, and the central gear drives the gear set arranged between the lower splint and the upper splint in the gear box (the central gear and the gear set are located at the head of the transmission and correspond to 0.0001m 3 Measuring unit gear meshing), the gear at the transmission end in the gear se...
