Abstract
It the utility model is related to a kind of Anti-freezing water meter, including essentic-water-meter, metallic plate is fixedly installed on one side of essentic-water-meter, the alternating magnetic field metallic plate produced by electromagnetic oven generates heat, essentic-water-meter is heated by the heat transfer of metallic plate, the electromagnetic oven embeds wall or is suspended on wall, and electromagnetic oven includes rectifier, RF power conversion equipment and the spiral helicine load coil of flat, hollow.The utility model is to convert electric energy to high-frequency alternating magnetic field cutting Anti-freezing water meter metallic plate using electromagnetic induction principle, cyclic currents is produced in water meter metallic plate, and water meter metallic plate is directly set to generate heat rapidly using the short-circuit fuel factor generation heat of small resistor high current, then heat is conducted by heating water and essentic-water-meter in the past by contact of the water meter with metal flat again, so as to prevent water freezing from causing water meter to damage.
Description
Technical field
It the utility model is related to a kind of Anti-freezing water meter.
Background technology
Existing water meter is in the winter time in use, the situation freezing due to cold weather happens occasionally, particularly in China
The north, the water meter installed and used outdoors often result in water gage glass cover bursting by freezing so that water meter can not normal use.Cause
Stating the main reason for water meter is freezing is after water meter freezes reality under cold temperature, due to the water in table from liquid become solid-state when, its
Volume will become larger, and produce certain expansive force, so that the most weakness by water meter --- water gage glass cover racks, or even makes table
Other interior component damages, and then influence the normal operation of water meter.
Gu water meter how is protected to become the hot spot studied in the industry the problems such as normal use in cold environments.Mesh for this
The preceding antifreeze method taken in the industry：First, thermal insulation material is wrapped up outside water pipe or water meter, second, the tap allowed in family is opened,
Keep thread state.The first method effect when temperature is relatively low is undesirable, and second of method can cause the relatively billow of water resource
Take and the water of water undertaking damages.Either with or without more preferably more intelligent antifreezing measures.
Utility model content
The purpose of this utility model is to provide a kind of Anti-freezing water meter, prevents water meter to be damaged by frost.
The technical solution of the utility model is：A kind of Anti-freezing water meter, including essentic-water-meter, it is characterised in that essentic-water-meter
Metallic plate is fixedly installed on one side, the alternating magnetic field metallic plate produced by electromagnetic oven generates heat, and passes through metallic plate
Heat transfer heats essentic-water-meter, and the electromagnetic oven embeds wall or is suspended on wall, and electromagnetic oven includes rectifier, RF power
Conversion equipment and the spiral helicine load coil of flat, hollow.
In a detailed embodiment, metallic plate is removably disposed on essentic-water-meter side.
In a detailed embodiment, set temperature sensor detects water temperature in essentic-water-meter, and temperature sensor can
Communicated with electromagnetic oven.
In a detailed embodiment, heat-conducting silicone grease is scribbled in essentic-water-meter and metal sheet separation.
In a detailed embodiment, the size requirement of metallic plate can be total to for a water meter, or multiple water meters
With.
In a detailed embodiment, the water inlet of Anti-freezing water meter is connect with water outlet using high-temperature resistance plastice pipe.
The main operational principle of the utility model is to convert electric energy to high-frequency alternating magnetic field using electromagnetic induction principle to cut
Anti-freezing water meter metallic plate is cut, cyclic currents is produced in water meter metallic plate（Vortex）, and utilize the short-circuit thermal effect of small resistor high current
Heat, which should be produced, directly makes water meter metallic plate generate heat rapidly, is then again conducted through heat by contact of the water meter with metal flat
Heating water and essentic-water-meter are removed, so as to prevent water freezing from causing water meter to damage.
The antifreeze scheme of the utility model effect when temperature is relatively low is more satisfactory, and will not waste water resource.
Brief description of the drawings
Attached drawing 1 is the Anti-freezing water meter top view of one embodiment of the utility model.
Attached drawing 2 is the winterization system of an embodiment（Including three Anti-freezing water meters）Top view is installed.
Attached drawing 3 runs block diagram for the utility model winterization system.
Wherein, essentic-water-meter 1, metallic plate 2, fixing screws 3, high-temperature resistance plastice pipe connect 4, wall 5, electromagnetic oven 6.
Embodiment
Such as Fig. 1,2, the Anti-freezing water meter of one specific embodiment of the utility model, 1 one sides of essentic-water-meter are plane, are put down
There are two screw holes to be used for fixed metal plate 2 on face, another side structure does not require.
Metallic plate 2 is a surface plate, and material is the metal materials such as iron, aluminium.Metallic plate 2 is detachable, and peace is left on metallic plate 2
The via of cartridge screw.If water meter, which need not do antifreeze function, can not install this metallic plate.2 size of metallic plate can a table one
With, also can multilist share.
Fixing screws 3 are used to fix essentic-water-meter and metallic plate.
Electromagnetic oven can directly use electromagnetic oven, also may customize a wall or the electromagnetic oven being suspended on wall of embedding and make
For heating equipment.The electromagnetic oven includes rectifier, RF power conversion equipment and the spiral helicine load coil of flat, hollow,
Current Voltage is converted to direct current by rectifier, and direct current is changed into the high frequency more than audio through RF power conversion equipment
Alternating current, high-frequency alternating current is added on the spiral helicine load coil of flat, hollow, thus produces high-frequency alternating magnetic field.
This electromagnetic oven can communicate with water meter at the same time, be not limited to wirelessly or non-wirelessly.
Water meter, which comes with temperature sensor, can perceive water meter water temperature, and can be communicated with external electromagnetic stove.
Heat-conducting silicone grease is applied in the plane of metallic plate 2 and 1 side of essentic-water-meter, for filling the flat of essentic-water-meter side
Gap between face and metallic plate 2, increases heat conduction.
High-temperature resistance plastice pipe connects 4 water inlets and water outlet for being used to be connected to Anti-freezing water meter, prevents heat from passing through water pipe pipe
Road loses, and increases heat insulation function.
