Abstract
A kind of electric operating staircase, it comprises staircase body and is arranged on the hazard detection system on staircase body, described hazard detection system comprises battery, microswitch, triode and alarm, position corresponding with the hand of staircase Ziren person on staircase body is provided with the groove covered by flexible sheet, described microswitch is arranged in groove, its trigger head is corresponding with flexible sheet, the constant open contact one termination anode of microswitch, the other end connects the base stage of triode through coupling resistance and is provided with pull down resistor, battery two ends are connected to after described alarm and triode are connected in series.The utility model has set up hazard detection system on the basis of conventional electric power operation staircase, when only having the personnel of staircase normally to hold the ladder, hazard detection system is not just reported to the police, leave once the personnel of staircase unclamp staircase, hazard detection system will send alarm signal automatically, prompting operating personnel stop operation, and this ensures that theres the safety of operating personnel.
Description
Technical field
The utility model relates to the staircase of use when a kind of electric power overhaul personnel carry out ascend operation, belongs to ladder technical field.
Background technology
Often need in electric power overhaul process to carry out ascend operation by ladder; for ensureing the safety of operating personnel; must arrange the personnel of special staircase during ascend operation, if the personnel of staircase leave for some reason, ascend operation personnel just must stop operation or take other safeguard measure.But because existing staircase does not have warning device, after the personnel of staircase leave, operating personnel often and ignorant, therefore cannot guarantee the safety of operating personnel.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of electric operating staircase with danger warning function, enables ascend operation personnel Timeliness coverage potential safety hazard.
Problem described in the utility model realizes with following technical proposals:
A kind of electric operating staircase, formation comprises staircase body and is arranged on the hazard detection system on staircase body, described hazard detection system comprises battery, microswitch, triode and alarm, position corresponding with the hand of staircase Ziren person on staircase body is provided with the groove covered by flexible sheet, described microswitch is arranged in groove, its trigger head is corresponding with flexible sheet, the constant open contact one termination anode of microswitch, the other end connects the base stage of triode through coupling resistance and is provided with pull down resistor, battery two ends are connected to after described alarm and triode are connected in series.
Above-mentioned electric operating staircase, NAND gate and pyroelectric human body infrared sensor is also comprised in formation, described pyroelectric human body infrared sensor is fixed on staircase body lower part and corresponding with staircase Ziren person, and the switching signal that microswitch exports sends into the base stage of triode again through coupling resistance after first carrying out NAND operation with the output signal of pyroelectric human body infrared sensor in NAND gate.
Above-mentioned electric operating staircase, described microswitch arranges two, and they are corresponding with the right-hand man of staircase Ziren person respectively.
Above-mentioned electric operating staircase, described hazard detection system is also provided with manual master switch, and described manual master switch is connected with serial battery.
Above-mentioned electric operating staircase, described alarm is arranged on the top of staircase body.
Above-mentioned electric operating staircase, described alarm is buzzer.
The utility model has set up hazard detection system on the basis of conventional electric power operation staircase, when only having the personnel of staircase normally to hold the ladder, hazard detection system is not just reported to the police, once the personnel of staircase unclamp staircase or leave, hazard detection system will send alarm signal automatically, prompting operating personnel stop operation, and this ensures that theres the safety of operating personnel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the electrical schematic diagram of hazard detection system.
In figure, each label is: 1, staircase body, 2, flexible sheet, and B, battery, K1, manual master switch, K2, microswitch, BJ, alarm, H, pyroelectric human body infrared sensor, U1, NAND gate, Q, triode, R1, pull down resistor, R2, coupling resistance.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, the utility model is made up of staircase body 1 and hazard detection system.Hazard detection system comprises battery B, manual master switch K1, microswitch K2, alarm BJ, pyroelectric human body infrared sensor H, NAND gate U1, triode Q, pull down resistor R1 and coupling resistance R2.Alarm BJ is arranged on the top of staircase body 1, and operating personnel is easy to the chimes of doom hearing that it sends.Microswitch K2 is arranged on position corresponding with the hand of staircase Ziren person on staircase body 1, just triggers microswitch K2 when the personnel of staircase normally hold the ladder.Pyroelectric human body infrared sensor H is arranged on the bottom of operation staircase, and this sensor can only receive the infrared signal that staircase Ziren person sends, and can not receive the infrared signal that operating personnel sends.Flexible sheet 2 is for expanding the trigger range of microswitch K2.Manual master switch K1 is as the starting switch of whole hazard detection system.
Before ascend operation, manual master switch K1 disconnects, and hazard detection system does not work.When needing ascend operation, first closed manual master switch K1, makes hazard detection system in running order.When there being people's staircase period of the day from 11 p.m. to 1 a.m, the hand of staircase Ziren person is held up just on flexible sheet 2, now the constant open contact of microswitch K2 closes, high level signal is exported to NAND gate, meanwhile, pyroelectric human body infrared sensor H also exports high level signal, so NAND gate output low level signal after receiving the infrared signal that staircase Ziren person sends, triode Q ends, and alarm BJ does not report to the police; If staircase person unclamps staircase, the constant open contact of microswitch K2 disconnects, and NAND gate will export high level signal, and alarm BJ is reported to the police.If staircase person leaves and microswitch K2 breaks down, after pyroelectric human body infrared sensor H can't detect infrared signal, alarm BJ still can report to the police, and which improves the reliability of this device.
, buzzer FM sends alarm signal.
