A smart meter based on the Internet of Things that is convenient for wiring and moisture-proof and short-circuit proof

Abstract

The invention relates to an intelligent meter which facilitates wiring and prevents dampness and a short circuit based on the internet of things. The intelligent meter comprises a meter shell, a protective plate and a lifting mechanism, the lifting mechanism comprises a second hinging unit, a lifting unit, a movable ring, an I-shaped block, a lifting rod, a first connecting rod and a second connecting rod, the meter shell is internally provided with a driving mechanism, two vertical rods and several wiring units, and the driving mechanism comprises a second driving motor, a driving gear, a frame, two driven gears and two fixed blocks. According to the intelligent meter which facilitates wiring and prevents the dampness and the short circuit based on the internet of things, the vertical rods are driven by the driving mechanism to move upwards, so that a fastening unit clamps a signal line on a copper sheet, wiring is completed, and since no external tool needs to be assisted in, wiring is convenient; besides, after wiring is completed, the lifting unit drives the protective plate to rotate downwards and covers the portion above a wiring socket, external water drops are prevented from entering the meter through the wiring socket, the short circuit is not caused, the meter is not damaged, and therefore the safety coefficient of the meter is increased.

Description

technical field [0001] The invention relates to the field of smart meters, in particular to a smart meter based on the Internet of Things that is convenient for wiring and is moisture-proof and short-circuit proof. Background technique [0002] Intelligent instrument, also known as intelligent electromagnetic flowmeter, adopts the world's advanced technology and uses constant current and low frequency three-valued rectangular wave excitation, which not only has the advantages of rectangular wave magnetic field, but also overcomes the shortcomings of sine wave magnetic field; it can also eliminate power supply voltage fluctuations, Errors caused by power frequency changes and excitation coil impedance changes; and have excellent zero point stability and are not affected by fluid noise interference, so they have the characteristics of high stability and high reliability. [0003] In order to connect external signals, there are usually several terminal posts on the back of the ...

AI Technical Summary

Problems solved by technology

[0003] In order to connect external signals, there are usually several terminal posts on the back of the smart instrument to connect external signal lines, communication lines, power lines, etc., but these terminal posts are usually fixed by screws to fix the signal lines on the instrument. Therefore, when wiring, it is necessary to use a screwdriver that matches the screw to perform wiring and dismantling operations. The operation is cumbersome, and the screw is set outside, which is prone to oxidation and rust, and it is also prone to slipping during the process of turning the screw. Not only that, Since the wiring screws are exposed to the outside, it is easy to cause a short circuit of the wiring screws when water droplets accumulate on the watch case in some humid areas, causing damage to the circuit components inside the smart meter
