At present, mine high and low voltage switch can only accomplish after having a power failure to hang " someone work forbid power transmission " board side by side special messenger keep an eye on switch, prevented people's power transmission.Many people, when same switch load side work, must send many people to keep an eye on switch, prevent people's power transmission.Sometimes there is power transmission after operate miss, will the generation of personnel casualty accidents be caused.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of coded lock blocking device, power transmission after preventing operate miss and cause the generation of personnel casualty accidents, thoroughly to stop artificial misdelivery electricity and the accident that causes occurs, ability power transmission after only having power failure to unlock in person, to overcome the above-mentioned defect that prior art exists.
The technical scheme of the utility model technical solution problem is as follows: coded lock blocking device comprises lockset, coded lock and power failure notice board; The rivet composition that lockset comprises left locking plate, right locking plate and left and right lock sheet groups is fitted together; Left locking plate comprises board body part and extends the latch part be bent to form from board body part one side, right locking plate is identical with the structure of left locking plate, left locking plate and right locking plate arrange the hole of rivet hole, lock-receiving aperture and extension notice board, both are assembled into one through the rivet hole of left locking plate and right locking plate by rivet, power failure notice board is assembled on left locking plate by the mode of riveted joint, and lockset can lock in the left locking plate and right locking plate lock-receiving aperture by snap close by coded lock.
Lock-receiving aperture described above is arranged at the middle position of board body part near upper end of left lock body.
Lock-receiving aperture described above is arranged in the middle part of the board body part of left lock body and right lock body, and lock-receiving aperture can arrange two rows, and above-mentioned two row's lock-receiving aperture can for multiple coded lock, thus improve many people have a power failure use time safety factor.
Power failure notice board described above and left locking plate can 360 ° rotate, be convenient to electrician easy to carry.
Access to your password at the snap close place of all kinds of high-tension switch cabinet, high-explosive switch, the high side switch moving change, low-voltage vacuum switch, low-voltage feeder switch, illumination integrated protection locking locking device, reach multiple spot construction locking on same circuit, only have the object that I could unlock.Stop, in electrical overhaul work, arbitrarily to stop the hidden danger of power transmission, really play the effect of effective electric blocking, the personnel that thoroughly stopped misdeliver electricity.Accomplish that the blocking device of all switches must reliably prevent power transmission without authorization, prevented operation of uncapping without authorization; Accomplished that all switch handles locking locking device that must access to your password when cutting off the electricity supply is in blocking, and by being printed with on power failure notice board the warning sign of " someone works, forbid power transmission " printed words; Accomplish to only have the personnel performing this work just to have the right take off this board and unlock power transmission, " the people one locks " system of execution, who has a power failure, and who locks, thus avoid other people and to misdeliver electricity and cause the generation of personnel casualty accidents, do not need can only to accomplish after mine high and low voltage switch has a power failure to hang simultaneously yet " someone work forbid power transmission " board side by side special messenger keep an eye on switch and bring the high investment of manpower.
The beneficial effects of the utility model are: the accident thoroughly having stopped artificial misdelivery electricity occurs, ability power transmission after only having power failure to unlock in person, and only adhere to that " people one locks " makes, stopping power transmission accident can never occur again; Can manpower be saved, there is no need to keep an eye on switch appointment special messenger, increase work efficiency.
