Abstract
The utility model relates to a safety switch and staircase flood control safe operation system that adopts it for staircase, set up in the staircase flood control safe operation system of control staircase operation, erupt simultaneously the out water level detection device of detected signal of staircase flood control safe operation system water level in the foundation ditch that detects the staircase lower part, the safety loop of control staircase operation, because detection signal control's drainage device and safety switch for the staircase, safety switch includes a set ofly by detecting signal trigger and inserting safety loop's normal close dry contact for the staircase, a set of by detect signal trigger and be connected with drainage device normally open the dry contact, monitored control system looks signal connection in the monitor of normal close dry contact and staircase. The utility model provides an adopt above -mentioned for staircase safety switch's staircase flood control safe operation system. The utility model discloses being in the high water level environment can, the staircase in time start the drainage when to the safe operation of staircase has been ensured.
Description
Technical field
This utility model relates to a kind of safety switch used in escalator and adopts the staircase flood control safety of this safety switch to run system.
Background technology
Existing outdoor version staircase is equipped with flood control switch, for controlling staircase after the water level of detection staircase bottom foundation ditch, when water level is too high, stops staircase and runs, it is prevented that cause danger.General flood control switch only two groups of normally-closed contacts, when water level is too high, utilizing this normally-closed contact to disconnect and cut off staircase safety return circuit, and send BAS and monitor fault-signal to the monitoring system in Control Room, monitoring indoor occupant starts draining pump artificially according to BAS pilot signal and drains the water away.This scheme exists and starts hidden danger not in time (cannot judge the state of staircase during communication abnormality, personnel start not in time etc.).
Summary of the invention
The purpose of this utility model is to provide a kind of staircase safety switch that can start draining when high water level in time.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of staircase safety switch, it is arranged at and controls in the staircase flood control safety operation system that staircase runs, described staircase flood control safety runs system and includes detecting water level in the foundation ditch of described staircase bottom and send the condensate tank of dehumidifier of detection signal, control the safety return circuit that described staircase runs, the drainage arrangement controlled based on described detection signal and described staircase safety switch, described staircase safety switch includes one group of normally closed dry contact being triggered and being accessed described safety return circuit by described detection signal, one group of normally opened dry contact triggered by described detection signal and be connected with described drainage arrangement, described normally closed dry contact connects with signal with the monitoring system in the Control Room of described staircase.
Preferably, described drainage arrangement includes manual control switch, and described normally opened dry contact and described manual control switch's phase also connect.
This utility model also provides for a kind of staircase flood control safety that can start draining when high water level in time and runs system.
A kind of staircase flood control safety runs system, including detecting water level in the foundation ditch of described staircase bottom and sending the condensate tank of dehumidifier of detection signal, control the safety return circuit that described staircase runs, the drainage arrangement controlled based on described detection signal and staircase safety switch, described staircase safety switch includes one group of normally closed dry contact being triggered and being accessed described safety return circuit by described detection signal, one group of normally opened dry contact triggered by described detection signal and be connected with described drainage arrangement, described normally closed dry contact connects with signal with the monitoring system in the Control Room of described staircase.
Preferably, described drainage arrangement includes manual control switch, and described normally opened dry contact and described manual control switch's phase also connect.
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model can start draining in time when staircase is in high water level environment, thus having ensured the safe operation of staircase.
Accompanying drawing explanation
Accompanying drawing 1 is the principle schematic of staircase safety switch in this utility model.
Accompanying drawing 2 is the wiring schematic diagram of the normally closed dry contact of staircase safety switch in this utility model.
Accompanying drawing 3 is the wiring schematic diagram of the normally opened dry contact of staircase safety switch in this utility model.
In the figures above: 1, normally closed dry contact；2, normally opened dry contact；3, safety return circuit；4, manual control switch；5, draining pump.
Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, this utility model is further described.
Embodiment one: a kind of staircase flood control safety runs system, including condensate tank of dehumidifier, safety return circuit 3, drainage arrangement and staircase safety switch.Condensate tank of dehumidifier is for detecting in the foundation ditch of staircase bottom water level and sending detection signal, and it includes a float switch.Safety return circuit 3 is used for controlling staircase and runs.Staircase safety switch includes one group to be triggered and the normally closed dry contact 1, a group in access security loop 3 is triggered and the normally opened dry contact 2 that is connected with drainage arrangement by detecting signal by detecting signal, and normally closed dry contact 1 connects with signal with the monitoring system in the Control Room of staircase.Drainage arrangement is controlled based on detection signal, and for being discharged by the water in foundation ditch, it includes draining pump 5 and the manual control switch 4 being connected with draining pump 5, and one group of normally opened dry contact 2 in staircase safety switch and manual control switch 4 phase also connect.
When condensate tank of dehumidifier detects that in the foundation ditch of staircase bottom, water level reach a certain height, its float switch action and produce detection signal, normally closed dry contact 1 in staircase safety switch disconnects, thus safety return circuit 3 to control staircase out of service, and by the mode of fault collection point, fault message is sent the Control Room to staircase.Meanwhile, the normally opened dry contact 2 in staircase safety switch closes, and starts drainage arrangement and carries out draining.Drainage arrangement can also adopt Starting mode manually.Compared with original mode being only capable of and manually booting, drainage arrangement starts more timely, also safer.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalences made according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
