Abstract
The utility model relates to a double dry-reed flow sensor of a water meter, which comprises a magnetic rotary wheel 1, a copper housing 2, a rubber sealing ring 3, a working dry-reed 4, an auxiliary dry-reed 5, a four-core cable 6, a rubber outer sleeve 7, water meter glass 8, etc. The double dry-reed flow sensor of a water meter can effectively detect the failure of a sensor and certain water stealing behaviors, such as that a ferromagnetic body is arranged on a water meter, a signal cable is cut off or is strapped to short circuit by metal wires, etc. The design and method of the double dry-reed flow sensor of a water meter can be also used for the remote transmission measuring of a kilowatt-hour meter and a gas meter in order to form a more perfect and advanced automatic meter-reading system of a water meter, a kilowatt-hour meter and a gas meter.
Description
The utility model relates to a kind of telemetering water meter flow sensor.
In the prior art, remote transmitting water meter tongue tube commonly used and rotation magnetic patch constitute the magnetic-pulse flow sensor, and with cable traffic pulse are passed in the data acquisition unit of far-end.The advantage of this method is simple, reliable, not consumed power.But also there is a serious problem in it.When being exactly the people with kicker magnet near sensor, tongue tube wherein will remain closed, even water meter can not send metrical pulse changeing, making some people steal water has had opportunity.
The purpose of this utility model just provides a kind of double dry-reed pipe water meter flow sensor that can supervise and find to steal the water behavior to a certain extent.Described surreptitiously water behavior comprises, puts kicker magnet on water meter, cut off signal cable or with tinsel signal cable is tied up short circuit etc.
The technical solution of the utility model is design like this: a kind of double dry-reed pipe water meter flow sensor, be characterized in: it comprises the magnetic runner 1 that is contained on the indicator of water gauge axle, be positioned at the copper shell 2 that magnetic runner 1 top is the hollow bolt shape, with the quad 6 of the signal is far passed, the water gage glass 8 that the center is porose; By rubber seal 3 sealings, back cushion sheet 9 and double nut 10 are fixing between described copper shell 2 and the water gage glass 8; Work tongue tube 4 is installed in the bottom in the copper shell 2, and is near from the magnetic runner, and auxiliary tongue tube 5 is contained in the middle and upper part in the copper shell 2, and is far away from magnetic runner 1; First heart yearn of described quad 6 is concentric line, connects the common port of work tongue tube 4 and auxiliary tongue tube 5, and second heart yearn is short-circuit line, and with the concentric line short circuit, the 3rd heart yearn is boost line, connects the other end of auxiliary tongue tube 5; The 4th heart yearn is front, connects the other end of work tongue tube 4.
The utility model utilizes double dry-reed pipe and short-circuit line structure to solve sensor fault dexterously and steals the monitoring problem of water behavior.For the application of remote transmitting water meter and the popularization of Automatic meter reading system provide wide prospect more.
Fig. 1 is a cut-away view of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Magnetic runner 1 is contained in water meter 0.01m
3On the needle pivot of scale, two magnetic patch are arranged on it, whenever circling, (0.05m is closed in each pulse to two magnetic-pulses of generation
3).The copper shell 2 that is positioned at magnetic runner 1 top is to make the hollow bolt shape with non-magnet material, and the bottom is thin and obstructed, and copper shell 2 passes hole and the pad 9 on rubber seal 3, the water gage glass 8, is fastened on the water gage glass 8 by double nut 10.Two tongue tubes are arranged in the copper shell 2, and the tongue tube 4 of wherein working is in the bottom of copper shell 2, and is near from magnetic runner 1, can detect magnetic-pulse; And auxiliary tongue tube 5 is far away from magnetic runner 1, can not detect magnetic-pulse, is normally open.Signal is drawn by quad 6, and four heart yearns are concentric line, short-circuit line, boost line and front from left to right successively among the figure.Usefulness encapsulating modes such as tongue tube in the copper shell 2 and heart yearn are fixed.Rubber sleeve 7 plays a part to beautify outward appearance and pilot cable.
Under the normal condition, work tongue tube 4 moves with the rotation of magnetic runner 1, and auxiliary tongue tube 5 is often opened, and make the boost line open circuit, and short-circuit line remains short-circuit condition.As the people with kicker magnet when the sensor, must cause auxiliary tongue tube 5 closures, after the data acquisition unit of far-end detects this incident, write down the date and time of generation etc., and the notice host computer is made corresponding processing.In addition, when quad 6 is broken, when short-circuit line becomes open circuit, or quad 6 is by wire tying, and when causing the boost line short circuit, the remote data collector can both in time detect these ANOMALOUS VARIATIONS, and makes corresponding processing.This scheme not only can detect above-mentioned surreptitiously water behavior, and can judge some fault of sensor, as tongue tube damage, cable break or short circuit etc.
Thinking of the present utility model and method also can be used for teletransmission metering aspects such as watt-hour meter metering and gas meter, and solving sensor fault judgement and people is stealing and the monitoring of stealing the gas behavior etc.The sensor that adopts the utility model to provide can constitute various intelligence, improve and advanced water, electricity, gas Automatic meter reading system.
