Description
Technical field
The utility model relates to warning device field, is specifically related to the temperature-control alarm for ammeter box.
Background technology
Ammeter box is used to install ammeter, facilitates the device of record management resident family of Utilities Electric Co. electricity consumption situation.Ammeter box generally comprises casing and the ammeter in casing, the electric wire be connected with ammeter and switch.Along with the quickening of Urbanization in China, various places are all that high building stands in great numbers.Conveniently manage concentratedly, the ammeter box in high-rise building generally adopts centralized ammeter box, namely in a casing, arranges multiple ammeter, many wires and multiple switch.
Because the electric wire that centralized ammeter box holds is various, be easy to because aging circuit, Rig up error, electricity consumption overload or the danger causing ammeter box to catch fire because environment temperature is too high.What the material due to electric meter box body often adopted is insulating material, and the fire in ammeter box is generally difficult to spread out the fire failure causing the intensity of a fire larger, so present ammeter box does not generally install warning device.
But the burning of ammeter box inside can cause the toxic gases such as the carbon monoxide of dense smoke and adjoint dense smoke, the life security of high risks resident families.Especially when pyrophoricity accident occurs ammeter box within night, the intensity of a fire likely can not spread, but the people during the gas such as carbon monoxide produced can make to sleep soundly get killed, and especially in airless territorial environment, this toxic gas endangers the life threat caused can be larger.In addition, stack more place at some foreign material in high temperature environments, but the too high temperature of electric meter box body and the flare that spills from gap still may cause fire spreading, finally very likely cause large-scale fire failure.Therefore, be extremely necessary alarm to be installed on ammeter box to the action of saving oneself reminding resident family to carry out fire prevention gassing in time.
Utility model content
The utility model provides a kind of temperature-control alarm for ammeter box, does not generally install to solve existing ammeter box the problem that alarm cannot send fire alarm in time.
For overcoming the above problems, adopt following scheme:

Principle of work: the outside surface base plate of the temperature-control alarm being used for ammeter box being close to electric meter box body, when in ammeter box, fire accident occurring, electric meter box body heating-up temperature raises.Because base plate is metal good thermal conductivity, temperature is passed to the temperature sensor be attached thereto by the base plate be close to electric meter box body outside surface.Temperature sensor converts temperature signal to electrical signal transfer to microprocessor, when the thermometric equivalents that the signal that microprocessor receives processes the signal that rear discovery receives as calculated is higher than the desired temperature be preset in microprocessor, the hummer sounding alarm that Microprocessor S3C44B0X is attached thereto.Meanwhile, the motor of Microprocessor S3C44B0X jetting system rotates, and motor drives jetting pump to rotate and makes the jet pipe be connected with jetting pump outwards spray condensed fluid, reduce ammeter box temperature, stop fire spreading.
Beneficial effect:
1. base plate is metal base plate, and base plate is close to the outside surface of described electric meter box body and is fixed on electric meter box body; Because metal has good thermal conductivity, base plate is facilitated fast the temperature of electric meter box body to be passed to temperature sensor.
2. in shell, be provided with the temperature sensor be electrically connected with base plate, the microprocessor be electrically connected with temperature sensor, the hummer be electrically connected with microprocessor and the jetting system be connected with microprocessor; Transfer temperature signal to electric signal after facilitating temperature sensor to receive the next temperature of base plate transmission and reach microprocessor, preset value is contrasted after microprocessor receives signal, when the temperature of electric meter box body is higher than preset value, Microprocessor S3C44B0X hummer sounding alarm also controls jetting system injection cooling.
3. the jetting pump be provided with motor in jetting system, being rotationally connected with motor and the jet pipe be connected with jetting pump, jet pipe is equipped with condensed fluid and stretches out shell; Facilitate motor to rotate and drive jetting pump to rotate, make playpipe spray condensed fluid, because playpipe stretches out shell, condensed fluid can be made all to eject, electric meter box body is lowered the temperature rapidly, stop fire spreading.
4. the utility model can, when the ammeter box generation condition of a fire or the temperature too high likely generation condition of a fire, in time by hummer sounding alarm, remind resident family to note gas defence of putting out a fire.And lowered the temperature in time by the jet pipe injected cool lime set of jetting system, prevent the fire spreading in ammeter box or electric meter box body temperature is too high causes foreign material spontaneous combustion around.
Scheme two: on the basis of scheme one further, described jet pipe stretches out the two sides of described shell respectively, and the two ends of described jet pipe have spout, and the length of described jet pipe is greater than the length of base plate; The condensed fluid that jet pipe is sprayed can not be ejected on base plate, and condensed fluid is all ejected on ammeter box, and the saving being conducive to condensed fluid uses, and makes condensed fluid reduce the temperature of ammeter box to greatest extent, stops fire spreading.
Scheme three: on the basis of scheme one further, described base plate is copper soleplate, good and the low price of the thermal conductivity of copper, facilitates base plate in time the temperature of electric meter box body to be passed to temperature sensor, reduces the production cost of the temperature-control alarm being used for ammeter box simultaneously.
Scheme four: on the basis of scheme one further, the outside surface of electric meter box body is close in the bottom surface of described base plate, and end face and the side of described base plate scribble insulating waterproof layer, protection base plate is avoided wet by waterly causing base plate to be oxidized or electric leakage.
Scheme five: on the basis of scheme one further, the area of described base plate is greater than the cross-sectional area of described shell, and described shell is positioned at the center of described base plate, and the part that described base plate exceeds described shell is circumferentially with mounting hole; Be conducive to the whole machine balancing for the temperature-control alarm of ammeter box and installation.
Scheme six: on the basis of scheme two further, described shell is not provided with downward hole by the two sides that jet pipe runs through; Hole can avoid dust to enter in shell downwards, does not affect hummer simultaneously and is spread out of by sound, be conducive to chimes of doom transfer spreading.
