Preferably, in order to guarantee that the enough protection scopes of mechanism of animals 20, the area of the plate 21 are pushed up greater than main body 1
The area in portion.
When the electric energy meter is run, in order to control the temperature inside main body 1 in suitable range, transport electric energy meter normally
Turn, the refrigeration mechanism 14 in electric energy meter brings into operation, and the low-pressure steam of 14 inner refrigerant of refrigeration mechanism is sucked simultaneously by compressor 18
Boil down to high steam heel row is condensed into highly pressurised liquid, highly pressurised liquid in 8 mesohigh refrigerant vapour of condenser to condenser 8
Enter evaporator 16 by fluid reservoir 17, is evaporated under corresponding low pressure in 16 mesohigh liquid of evaporator, draw the heat of surrounding
Amount, reduces the temperature around evaporator 16, and due to being full of high-temperature gas inside main body 1, and evaporator 16 is located inside main body 1
Top, then top cold air and lower section hot-air occur convection current, hot and cold air, which is met, in convection process occurs heat
Amount conversion, reduces the air in main body 1 integrally, and refrigerant is again introduced into boil down in compressor 18 by expansion valve 19 later
High steam gradually decreases temperature in main body 1 to realize recycling for refrigerant.
Since refrigerant is changed into high-pressure liquid by high-pressure gaseous in condenser 8, refrigerant is condensed, according to heating power
Second law is learned, the state by changing refrigerant makes refrigerant discharge heat, to make the air themperature liter around condenser 8
Height, since condenser 8 is located at the lower section in protective shell 2, the high temperature air of lower section rises, and makes the gas temperature liter in protective shell
Height accelerates high-temperature gas circulation speed by the effect of fan 11 in the lower section of condenser 8 to reinforce gas flow rates,
To make to be rapidly filled with high-temperature gas in protective shell 2, under the high temperature conditions, the evaporation rate of water mist can not only be accelerated, while can
To avoid the formation again of water mist, in order to absorb the water mist in protective shell 2, it is equipped with drying layer 9 in 2 inner top of protective shell, works as height
When warm air drives water mist evaporation, the moisture in water mist rises and is absorbed by the wood dust in drying layer 9, to further avoid
Water mist is formed, and after water mist disappears, is made 7 number of display screen in main body 1 that can clean display, is facilitated the progress of meter reading operation.
In order to reinforce refrigeration effect, it is equipped with air inlet 5 in the over top of main body 1, air enters main body from air inlet 5
When 1 inside, large-scale particulate matter, dust in air are isolated effectively by gelatinization cotton coarse filtration net 6, prevent from entering main body
A blocking is caused inside 1, after air enters inside, by the effect of refrigeration effect, temperature is reduced, and the moisture of inside air is solidifying
Knot is flowed out outside main body 1 by condensate pipe 13 from outlet pipe 12, and the shape of saturating rain condensate pipe 13 is S-shaped, to extend
Water flow length of flow ensure that the sufficient flowing time of condensed water, and water flow takes away the heat inside main body 1 in flow process,
To make the work of electric energy meter internal component in ideal temperature, measurement accuracy and electric energy meter service life ensure that.
It is that, due to the effect of birds self gravity, the pressure of 21 lower section of plate is passed when there is flying bird to drop to electric energy meter top
Sensor 25 detects that pressure data has greatly changed, and at this time notifies pressure changing to the central processing in main body 1
Device, central processing unit control the driving unit operation of 21 top of plate, and driving motor 22 rotates, and make blade 24 by drive shaft 23
Rotation, birds, which are perceived after blade 24 rotates, will voluntarily leave electric energy meter, can clear away electric energy while blade 24 rotates
The cobweb on table top.When pressure recovery to original state, during pressure sensor 25 passes to the pressure condition monitored
Central processor, driving motor 22 stops operating at this time.The electric energy meter monitors the pressure condition at top by pressure sensor 25, and
It drives blade 24 to rotate using driving motor 22, birds is driven, the top of electric energy meter is made to keep cleaning.
Compared with prior art, the electric energy meter of the auto clear display makes high pressure by evaporator 16 in refrigeration mechanism 14
Liquid refrigerant is evaporated to low-pressure gas and absorbs heat, to reach cooling purpose, ensure that measurement accuracy and electric energy meter make
With the service life, high pressure refrigerant liquid is converted for higher pressure refrigerant gas by condenser 8 and discharges heat, is accelerated using fan 11
Water mist evaporation is accelerated in the flowing of hot-air, makes the number of display screen 7 that can clean display, facilitates the progress of meter reading operation, not only such as
This, by pressure sensor 25 monitoring top pressure condition, and using driving motor 22 drive blade 24 rotate, to birds into
Row is driven, and the top of electric energy meter is made to keep cleaning.
