Abstract
The utility model discloses an electric energy meter detection device that uncaps, including the upper cover and the lower cover of electric energy meter, its characterized in that the upper cover is equipped with near-infrared transmitting tube, near-infrared receiving tube and leaded light post, covers down and is equipped with the holophote, and the light signal that near-infrared transmitting tube sent reflects near-infrared receiving tube through the holophote, under near-infrared receiving tube can correctly receive the data that near-infrared transmitting tube sent, thinks that the incident of uncapping does not take place. The utility model discloses can not only make the electric energy meter have perfect leakproofness, enable this device long service life moreover, can not effectively improved the detection accuracy by manual operation.
Description
Technical field
The utility model relates to a kind of electric energy meter pick-up unit of uncapping.
Background technology
What at present domestic and international electric energy meter was uncapped the extensive employing of pick-up unit is mechanical type, and this detection of uncapping often needs electric energy meter loam cake and rear end cap to combine just can carry out, and the while has also been caused the sealing problem of structural member.
Traditional uncap detect be through end cap with after loam cake contacts fully, make by key contacts through pressure, the level through the detection button judges whether to uncap again; When taking place when uncapping; Button is upspring through mechanical elastic, and the key circuit level changes, and concludes that thus the incident of uncapping takes place.This pick-up unit of uncapping be because mechanical switch use for a long time can exist mechanical damage to cause button to upspring, not only limited service life but also can reduce the accuracy of detection.
The utility model content
It is high that the purpose of utility model design provides a kind of accuracy in detection, the electric energy meter of the long service life pick-up unit of uncapping.
This electric energy meter that the utility model the provides pick-up unit of uncapping; The loam cake and the lower cover that comprise electric energy meter; It is characterized in that said loam cake is equipped with near infrared transmission pipe, near infrared receives pipe and leaded light post, cover down completely reflecting mirror is housed that the light signal that near infrared transmission pipe sends reflexes near infrared through completely reflecting mirror and receives pipe; Receive pipe near infrared and can correctly receive near infrared and send under the data that pipe sends, think that the incident of not uncapping takes place.
Said leaded light post and completely reflecting mirror through ultra-sonic welded be separately fixed at loam cake with under cover.
The course of work of the utility model is that control module sends set of pulses signal to infrared transmission pipe; Corresponding a string specific data, pulse signal converts light signal into through sending pipe, is sent to total reflection lens through sending the leaded light post; Total reflection lens reflexes to light signal and receives the leaded light post; Receive the leaded light post and again light signal is delivered near infrared reception pipe, receiving tube converts light signal to electric signal, and control module receives electric signal and judges whether receive data equals to send data; The incident of not uncapping took place if data equate, control module whenever sent, receives a secondary data at a distance from one second.When loam cake was opened, after the transmission pipe sent data, because the effect of not arriving the leaded light post, data can't be sent to completely reflecting mirror, managed the data that send thereby receiving tube can't receive to send, and control module is judged as the incident generation of uncapping; When lower cover is opened, owing to there is not completely reflecting mirror, send data transfer behind transmission leaded light post, near infrared receives pipe can't receive this light signal, and control module is judged as the incident of uncapping and takes place.
The utility model detects prior mechanical and changes the electronic type detection into, can not only make electric energy meter have intact sealing, and can make this device long service life, can effectively not improved accuracy in detection by manual operation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As can beappreciated from fig. 1; This electric energy meter pick-up unit of uncapping comprises the loam cake 1 and lower cover 2 of electric energy meter; Be equipped with on loam cake 1 that near infrared sends pipe 3, near infrared receives pipe 4 and two leaded light posts 5, under cover completely reflecting mirror 6 be housed, wherein the installation of leaded light post and completely reflecting mirror is fixed through ultra-sonic welded.The light signal that near infrared sends pipe 3 transmissions is transferred to outside the electric energy meter through 5 prolongations of leaded light post; Reflex to another leaded light post 5 through optical mirror then; Receiving pipe by near infrared again receives; Can correctly receive the data that near infrared sends the pipe transmission when near infrared receives pipe, think that the incident of not uncapping takes place.The data that normally do not receive the transmission of near infrared transmission pipe when near infrared reception pipe think that the generation of the incident of uncapping is arranged.Can accurately judge whether the incident of uncapping like this, it is Electronic Control entirely that mechanical action does not all take place in entire work process, therefore can improve the serviceable life of this device and be not easy to take place manual operation.
Claims (2)
