Description

Non-transformer formula electronic water meter

Technical field

The utility model relates to a kind of water flow measurement instrument, particularly a kind of electric water meter.

Background technology

Along with the development of water meter counting, the electronic remote transmission water meter long-distance meter-reading system has replaced the conventional artificial meter reading method with full automatic meter reading method, so electronic water meter has also just obtained application more and more widely.Electronic water meter normally need use electric energy to support work such as its electronic circuit and teletransmission; But existing electronic water meter uses battery as power supply usually, and still along with the further expansion of water meter function, water meter has been born more work; For example be secondary instrument device power supplies such as data collector and self-contained electric system; Therefore the electric energy of its consumption also increases thereupon, in order to prolong the power-on time of battery, adopts high energy battery usually.But the serviceable life of battery is limited after all, when battery is used up, during like untimely replacing; Electronic water meter then can not be counted the current that flow through; And damage electronic component easily, and can not guarantee the water meter reliability like this, increased the cost of water supply company again.The way that solves remains the battery in the periodic replacement electronic water meter, brings very big inconvenience to the user.Some water flow measurement instrument still adopts the mechanical type water meter in addition, can not adapt to the development of electronic remote kilowatt meter reading-out system more.

Summary of the invention

The technical matters that the utility model solves is improved a kind of battery that need not to regularly replace on the basis of existing machinery formula water meter; Water meter self can provide the electronic water meter of electric energy; Can make the user need not to regularly replace the requirement that expensive battery can use the electronic remote kilowatt meter reading-out system, for the user brings very big facility.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is following.

Non-transformer formula electronic water meter; Comprise the mechanical type water meter that is arranged in the pipeline; Be provided with electronic sensor that is connected with mechanical type water meter runner and the batching counter that is used to count and show discharge that is connected with electronic sensor in the said mechanical type water meter, the water inlet end of said mechanical type water meter also is provided with the hydrogenerator that is used to electronic sensor and batching counter power supply.

The concrete structure of said hydrogenerator is: said hydrogenerator comprises the impeller that is arranged on mechanical type water meter water inlet end, go up magnet and be connected with impeller be arranged on the lower magnet in the housing, be arranged in the housing at interval through sealant between last magnet and lower magnet; The said magnet of going up is provided with magnetic induction coil on every side, and the output terminal of said magnetic induction coil is electrically connected with electronic sensor and batching counter respectively.

The improvement of the utility model is: the pipeline that is arranged in the hydrogenerator water inlet end is provided with and is used to the water pump that hydrogenerator provides kinetic energy.

Owing to adopted above technical scheme, the acquisition of technology progress of the utility model institute is following.

The utility model is simple in structure, with low cost, easy to use.Reequip based on the prior mechanical water meter, not only can not influence the use of former mechanical water meter, also can not influence the metering performance of the electronic water meter after the improvement.The utility model is owing to be on former mechanical water meter, to have increased circuit arrangement; Need not to insert in addition power supply; But through being arranged on water pump and the hydrogenerator in the pipeline; Can be the electric energy of electronic water meter need of work with the energy conversion of current, supply power, make electronic water meter after the improvement can not receive the influence of running down of battery for the electronic water meter after improving.The utility model makes original mechanical formula water meter be improved to electronic water meter in addition, makes it show water consumption through the display that the display line signal is arranged, and is convenient to the staff and checks.The use of the utility model has overcome the shortcoming that needs the periodic replacement battery in the prior art, has avoided the damage that in the process of repeated disassembled and assembled electronic water meter electronic water meter caused, has prolonged the serviceable life of electronic water meter.
