Description of the Invention The utility model relates to the technical field of water meters, in particular to an anti-freezing and antifreezing intelligent water meter.
BACKGROUND OF THE INVENTION Meters for measuring water flow in a water meter are mostly cumulative flow measurements of water and are generally classified into two types: a volumetric meter and a speed meter. Meter used to record the water consumption of tap water is installed on the water pipe. When the user discharges water, the pointer or wheel rotates on the watch to indicate the amount of water passing through.
With the progress of society, more and more intelligent products have entered our lives. Intelligent water meters have also appeared more and more in our lives, bringing great convenience to the management and reading of water meters. .
In daily life, water meters are mostly installed outdoors. In cold weather in winter, water freezes easily, causing the water meter to work effectively, and the water in the water meter may become large after freezing, which may cause The broken glass on the dial has caused troubles for people's daily life. Especially at the end of 2015, the cold blast air suddenly cooled. The temperature in the whole country, especially in the south, reached minus 10 degrees, and the water consumption of the residents' lives was under minus 10 degrees. Most of the phenomena of frost cracking and freezing damaged the flow of water overnight, causing great trouble to the people's lives and their ability to use normal water. For the installation environment and use characteristics of the water meter, the glass part of the water meter has always been tempered glass, transparent and easy to read, now need to design and develop antifreeze water meter glass instead of tempered glass, can guarantee the water meter is not broken, no leakage under the temperature of minus 30 °C. , does not affect the normal life of residents.
SUMMARY OF THE INVENTION To overcome the deficiencies of the prior art, the present invention provides an antifreeze antifreeze type smart water meter, which improves the freeze resistance of the water meter by changing the shape and material of the water meter antifreeze glass. 
The figure is a schematic diagram of the structure of the anti-freezing and antifreezing intelligent water meter of the utility model
Further, an upper surface of the copper cover is provided with a circular opening, and the circular opening is not smaller than the second circular table. The second round platform protrudes from the circular opening, the upper surface of the first round platform and the inner surface of the upper surface of the copper cover fit together, the side surface of the first round table and the inner surface of the copper cover. Affixed; the second circular platform protrudes from the circular opening, and a side wall of the second circular platform is adhered to the wall of the circular opening. The second circular table is arranged concentrically with the first circular table, and the diameter ratio of the second circular table to the first circular table is in the range of 7:10-9:10. The thickness of the second frustum is equal to the thickness of the upper surface of the copper cover, and the upper surface of the water meter glass is flush with the upper surface of the copper cover.
Further, a water meter upper cover is also included, and the water meter upper cover is pivotally mounted on the copper cover. The water meter glass was injection molded from PA12. The water meter movement is an intelligent water meter movement.
The utility model has the beneficial effects that the anti-freezing and antifreezing type intelligent water meter of the utility model replaces the original tempered glass by adopting a convex water meter anti-freezing glass made of transparent nylon, so that the anti-frozen performance of the water meter is achieved without affecting the reading of the water meter. Better, it can resist the water temperature below -30°C to ensure that the water meter does not break, no leakage, and does not affect the normal life of residents.
