Swivel meter

Abstract

The invention relates to a rotating ring type electric energy meter. The rotating ring type electric energy meter comprises a meter body and a digital display module. A power supply ring sleeves the digital display module. The power supply ring comprises a housing, a friction ring, a temperature difference ring plate, a flow stabilizer and a cooling ring. The cooling ring closely abuts against a low-temperature heat conducting plate. The friction ring closely abuts against a high-temperature heat conducting plate. The other annular surface of the friction ring is provided with a sealed heat transfer plate. The sealed heat transfer plate and the housing form a closed air ring. The sidewall of the air ring is provided with a unidirectional air outlet valve. The air ring is also provided with an air guiding pipe. The other end of the air guiding pipe is communicated with a power generating chamber. The surfaces of the high-temperature heat conducting plate and the sealed heat transfer plate which contact with the friction ring are frosted surfaces. The rotating ring type electric energy meter has advantages of exquisite structure, small space occupation, no requirement for battery change, sufficient electric power and brightness in use and data uploading, high convenience and high speed.

Description

technical field [0001] The invention relates to a power device, in particular to an electric meter. Background technique [0002] The electric meter is a common device for recording and displaying electric power data; the electric meters in the community are often placed on the ground floor of the residential buildings, and some residential houses place the electric meters in the house; It is inconvenient; at the same time, the digital display module of the meter is often powered by an external battery. Residents do not often use the meter and pay attention to the use of the battery except for emergencies and when reading the electricity consumption data of the month; therefore, when it is necessary to observe It will be cumbersome to replace the battery when it is found that the battery is exhausted during the data processing, which will bring great inconvenience to the normal use of residents; in addition, some electric meters rely on the power provided by the battery to u...
