Abstract
The invention provides a safety access door which comprises a door plate, a door frame, a storage battery, a time relay and an automatic resetting switch. The door plate, the door frame, the storage battery and the time relay are installed on a cabinet body, and the automatic resetting switch is arranged on the door frame and arranged corresponding to the door plate. The door plate is provided with a signal lamp. The storage battery and the signal lamp are connected to form a signal lamp loop through an abutting contact of the automatic resetting switch. An electromagnetic coil of the time relay and the storage battery are connected to form a switch loop through an initial contact of the automatic resetting switch. The output end of the time relay serves as a main switch of an external circuit. The external circuit is connected with a caution lamp and an alarm through the initial contact of the automatic resetting switch. The safety access door has the advantages of being scientific in design, high in safety and intelligent in control.
Description
Technical field
The present invention relates to a kind of door, specifically, related to a kind of safety inspection door.
Background technology
In the densely covered place of the circuit such as power plant or maintenance station, the safety of service work is the most important thing, and many electric power overhaul equipment all needs power-off to overhaul, and closes after master on off, to check its switch board, but in the numerous place of equipment, on-off ratio is more, the staff that place is not familiar with, particularly newly enter the easy maloperation of personnel, do not turn off the facility switching of needs maintenance, cause the danger of follow-up work greatly to improve.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, thereby the safety inspection door of a kind of design science, safe, Based Intelligent Control is provided.
To achieve these goals, the technical solution adopted in the present invention is: a kind of safety inspection door, comprise door-plate, doorframe, accumulator, the time relay being installed on cabinet and be located on described doorframe and the self-resetting switch of corresponding described door-plate setting, described door-plate is provided with signal lamp, and described accumulator and described signal lamp connect and compose signal lamp loop by the contact that compresses of described self-resetting switch; The solenoid of the described time relay and described accumulator connect and compose switch loop by the initial contact of described self-resetting switch, the output terminal of the described time relay is as the master switch of external circuits, and this external circuits is connected with warning lamp and alarm by the initial contact of described self-resetting switch.
The relative prior art of the present invention has outstanding substantive distinguishing features and significant progressive, specifically, the present invention designs a kind of safety inspection door applicable to various maintenance switch boards, on the doorframe of access door, corresponding door-plate is provided with self-resetting switch, door-plate is closed, self-resetting switch triggers and compresses contact, and door-plate is opened, and self-resetting switch triggers initial contact, the two ends that compress contact connect accumulator and signal lamp forms signal lamp loop, and light can be set as common color, and as green, this signal lamp represents that accumulator has electricity, and the circuit in safety inspection door is without extremely, the solenoid of described accumulator and the described time relay is connected by the initial contact of self-resetting switch, the output terminal of the time relay is as the master switch of external circuits, when door is opened, trigger initial contact, the solenoid of the time relay obtains electric, the time relay triggers, after the fixed time, external circuits master switch disconnects, cabinet dead electricity, warning lamp can glimmer always simultaneously, the not power-off of prompting staff's cabinet, alarm also can send warning message, if staff does not carry out power operation in this period, time relay auto-breaking, for service work provides further guarantee.Bright under the state that wherein signal lamp only cuts out at door.
It has advantages of design science, safe, Based Intelligent Control.
Accompanying drawing explanation
Fig. 1 is the structural representation of safety inspection door in the present invention.
Fig. 2 is the circuit diagram of safety inspection door in the present invention.
In figure: 1. door-plate; 2. doorframe; 3. signal lamp; 4. self-resetting switch; 5. alarm; 6. warning lamp; 7. the time relay.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of safety inspection door, comprise door-plate 1, doorframe 2, accumulator, the time relay 7 being installed on cabinet and be located on described doorframe 2 and the self-resetting switch 4 of corresponding described door-plate 1 setting, described door-plate 1 is provided with signal lamp 3, described accumulator and described signal lamp 3 connect and compose signal lamp loop by the contact that compresses of described self-resetting switch 4, when door-plate 1 cuts out, trigger the contact that compresses of self-resetting switch 4, signal lamp loop obtains electric, signal lamp 3 amounts, this signal lamp 3 is mainly used in indicating accumulator normal;
The solenoid of the described time relay 7 and described accumulator connect and compose switch loop by the initial contact of described self-resetting switch 4, the output terminal of the described time relay 7 is as the master switch of external circuits, this external circuits is connected with warning lamp 6 and alarm 5 by the initial contact of described self-resetting switch 4, when staff opens door-plate 1 and overhauls, self-resetting switch 4 loses the acting force that compresses of door-plate 1, recoil to initial contact, the solenoid of the time relay 7 obtains electric, the time relay 7 starts countdown, warning lamp 6 lights simultaneously, alarm 5 is reported to the police, warning staff takes care, not yet power-off in cabinet, after the time that elapsed time relay 7 is set, external circuits disconnects, equipment dead electricity in cabinet, can overhaul, while alarm 5 stop alarms, warning lamp 6 extinguishes, if external master switch cuts out, external circuits does not have electricity, opens the rear alarm 5 of door-plate 1 and warning lamp 6 and does not work, staff can relievedly operate, but the time relay 7 is still made above action, dual power-off, in case other staff carry out power-on servicing in unwitting situation.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present invention; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
