The water level detection device for the escalator pit comprises a lowest water level detection sensor, a warning water level detection sensor and a highest water level sensor, which are arranged in the pit from low to high and are electrically connected with a PLC (Programmable Logic Controller) control system, wherein the PLC control system is electrically connected with a water pump arranged in the pit, and can perform three sets of water level detection and treatment to the water level of the escalator pit, and effectively reduce the damage on escalator equipment and the harm to passengers.
Description
Technical field:
The utility model relates to the elevator technology field, relates in particular to a kind of staircase pit condensate tank of dehumidifier.
Background technology:
Staircase is a kind of circular flow step that has; The fixedly driven by power equipment of conveying people is used for tilting up or down; Its structure is mainly by step, step driving unit, driving host, drive disk assembly, nervous device, armrest system, metal construction, step roller track, cover plate, fishback, safety device and the electrical part parts that grade are formed up and down; Has continuous working; The characteristics that transportation volume is big are widely used in the vertical transport of the public places such as subway, light rail, station, airport, harbour, shop and mansion that the stream of people concentrates.
Traditional outdoor staircase usually because pit ponding, causes elevator device failure, electric elements to lose efficacy, when serious even can produce passenger's personal injury.
The utility model content:
The purpose of the utility model is to the deficiency of prior art a kind of staircase pit condensate tank of dehumidifier to be provided, and can staircase pit water level be detected and handle, and can lower the damage of staircase equipment effectively and reduce the personal injury to the passenger.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of staircase pit condensate tank of dehumidifier, it comprises lowest water level detecting sensor, warning water level detecting sensor and the highest water level detecting sensor that is set in turn in pit from low to high; Lowest water level detecting sensor, warning water level detecting sensor and highest water level inspection detect sensor and are electrically connected with the PLC control system, and the PLC control system is electrically connected with the lift pump that is arranged at pit.
Said lowest water level detecting sensor, warning water level detecting sensor and highest water level inspection detect sensor and all are connected with a water level detecting relay.
Said lowest water level detecting sensor is installed on from 150mm place, the bottom surface of pit.
Said warning water level detecting sensor is installed on from 200mm place, the bottom surface of pit.
Said highest water level detecting sensor is installed on from 300mm place, the bottom surface of pit.
The utility model beneficial effect is:
The said a kind of staircase pit condensate tank of dehumidifier of the utility model, it comprises lowest water level detecting sensor, warning water level detecting sensor and the highest water level detecting sensor that is set in turn in pit from low to high; Lowest water level detecting sensor, warning water level detecting sensor and highest water level inspection detect sensor and are electrically connected with the PLC control system; The PLC control system is electrically connected with the lift pump that is arranged at pit; Can carry out three cover water level detecting and processing to staircase pit water level, can lower the damage of staircase equipment effectively and reduce personal injury the passenger.
Description of drawings:
Fig. 1 is the schematic diagram of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, mark comprises normally closed some X1 of relay, relay normally open point L2, water level detecting relay 1, lowest water level detecting sensor 2, warning water level detecting sensor 3, highest water level detecting sensor 4, lift pump 5 among the figure; The described a kind of staircase pit condensate tank of dehumidifier of the utility model, it comprises lowest water level detecting sensor 2, warning water level detecting sensor 3 and the highest water level detecting sensor 4 that is set in turn in pit from low to high; Lowest water level detecting sensor 2, warning water level detecting sensor 3 and highest water level inspection detect sensor 4 and are electrically connected with the PLC control system, and the PLC control system is electrically connected with the lift pump 5 that is arranged at pit.Further, said lowest water level detecting sensor 2, warning water level detecting sensor 3 and highest water level inspection detect sensor 4 and all are connected with a water level detecting relay 1.Wherein, lowest water level detecting sensor 2 is used to start lift pump 5 functions; Warning water level detecting sensor 3 is to be used to control staircase operation sequential function, mainly is to realize through the software of PLC; Warning water level detecting sensor 3 is to be used to protect the equipment of staircase not receive the damage of rainwater.
Preferably, said lowest water level detecting sensor 2 is installed on from 150mm place, the bottom surface of pit, and warning water level detecting sensor 3 is installed on from 200mm place, the bottom surface of pit, and highest water level detecting sensor 4 is installed on from 300mm place, the bottom surface of pit.
The described a kind of staircase pit condensate tank of dehumidifier of the utility model, its principle of work is: when lowest water level detecting sensor 2 detects water level, start the lift pump 5 of pit, carry out the pit draining and handle.When warning water level detecting sensor 3 detects water level,, transfer halted state at once to if staircase is in the intelligence state of receiving guests; If staircase moves up or down, then with 0.1m/s
2Deceleration/decel slow down, out of service, warning water level detecting sensor 3 recovers normally just can normally start the staircase operation; When warning water level detecting sensor 3 detects water level, break off the safety return circuit of staircase, cut off the power supply of frequency converter, prevent the damage of frequency converter, treat that water level is lower than warning water level detecting sensor 3 after, it is normal that safety return circuit recovers.In sum; The described a kind of staircase pit condensate tank of dehumidifier of the utility model can carry out three cover water level detecting to staircase pit water level, when water level acquires a certain degree; Staircase is made relevant action, can lower the damage of staircase equipment effectively and reduce the personal injury to the passenger.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
