Novel electric energy meter two-dimensional code seal device and sealing method

Abstract

The invention discloses a novel electric energy meter two-dimensional code seal device and sealing method. The two-dimensional code seal device comprises a fixed cylinder bottom sleeve and a locking clamp cover, wherein the fixed cylinder bottom sleeve is placed into a screw hole of an upper cover of an electric energy meter, and the locking clamp cover plugs the fixed cylinder bottom sleeve and seals a locking screw. By the technology of printing two-dimensional codes on the flat top surface of the clamp cover, plastic package is unique, seal reproduction difficulty is high, reliability of confidentiality is enhanced, the flat top of a head cover and an electric energy meter shell are parallel and level in height and attractive after the locking clamp cover seals the electric energy meter, the locking screw is sealed, antitheft effects are fine, reproducible difficulty is high, the reliability of confidentiality is fine, sealing operation is simple, prying is prevented as a prying position is avoided, automated assembly seal can be realized, the electric energy meter cannot be opened without damaging the locking clamp cover as the locking screw cannot be touched, and seal confidentiality and electricity stealing prevention effects of the electric energy meter are achieved.

Description

technical field [0001] The invention relates to the field technology of electric energy meter sealing system, in particular to a new two-dimensional code sealing device and sealing method for electric energy meters. Background technique [0002] The energy meter seal is a device to prevent unauthorized people from opening the energy meter, which can prevent unauthorized people from changing the structure or setting of the energy meter to steal electricity. At present, in the power industry, the traditional sealing structure is to use the sealing line to pass through the plastic shell, seal the screw, and then insert the two ends into a sealing structure, and fix the sealing line by pressing or rotating, without damaging the sealing structure and Under the premise of breaking the sealing line, the sealing line cannot be pulled out, so that the sealing screw cannot be rotated, so that unauthorized people cannot unscrew the sealing screw, open the sealed structure, and play the...

AI Technical Summary

Problems solved by technology

This structure mainly has the following four deficiencies: first, the traditional seal needs to wear the seal line, the installation steps are cumbersome, and the sealing efficiency is low; second, the anti-theft performance of the traditional seal structure is poor; third, the lead used in the traditional seal , serious environmental pollution, and long-term exposure of installation staff to lead, which can easily cause poisoning; Fourth, traditional seals are not conducive to digital management and the need for efficient and automatic sealing

Although the existing technology has made many improvements to the seal structure, some of which do not need to wear the seal line, the installation steps have been simplified, but because the structure is still relatively complicated, and the correction between the seal hole and other parts is required, the installation operation It is cumbersome and cannot be automatically sealed; some improvements in the structure of the seal can temporarily prevent theft, but due to structural defects, the seal is relatively easy to age. After a period of time, the seal will reduce or lose the anti-theft performance. Frequent replacement is required, which increases management costs and is not conducive to implementation
