Abstract
The utility model relates to a gas cabinet piston position checking and alarming device which can detect the piston at the top of the gas cabinet in order to prevent the gas bag from deforming and the accident of gas leakage from occurring. The device is connected with the PLC controller by a plurality of sensors through the shielding cable, and the PLC controller is connected with a number display meter, a language alarm and an operation display meter for displaying the information of each sensor. All the measuring, judging and analyzing of the device are completed by an intelligent component. The utility model has reliable running, and the operator in the control room can clearly see the real time checking result for the height of different direction of the piston, and the data response speed is rapid, and the utility model is of convenient adjusting, which saves time and reduces working intensity, thereby avoiding causing damaging (1.5 damage) to the checking people on site. Once the date display is abnormal, the adjusting measures can be instantly adopted to effectively ensure the normal running of the gas cabinet.
Description
One, technical field:
The utility model relates to gas chamber top piston position and prevents that the air bag distortion from the detection alarm device of gas leakage accident taking place.
Two, background technology:
Gas chamber is the specific store container of explosive coal gas, and air bag is arranged in the gas chamber, and piston is arranged at its top, and how many pistons can moving up and down along with coal gas amount in the gas chamber.The height on each limit of gas chamber piston will remain unanimity, if inconsistently also will in time adjust, to prevent that tilting of the piston is serious so that the catastrophic failure of air bag distortion gas leakage takes place.The height detection of gas chamber top piston is most important to the safe operation of gas chamber with warning.The inspection of present gas chamber piston quality of balance is many to be finished by mechanical hook-up, and it exists shortcoming as follows: (1) mechanical hook-up failure rate height, precision is low, reacts insensitive, can accurately not reflect the true altitude position of piston.(2) manual observation has the result that many human factors have influence on observation.(3) testing staff can not observe a plurality of balance bobs simultaneously, breaks down as certain piston, and the alarm free function can not be found processing in the very first time again, may make glitch become major break down.(4) the gas chamber top always has a small amount of coal gas and exists, and testing staff's life security is constituted a threat to.(5) all open-air because of gas chamber, when checking, the cabinet top has very big potential safety hazard in the process up and down personnel.
Three, summary of the invention:
The utility model be for provide a kind of reliable, response speed is fast, resolution is high, rapid, digital demonstration easy to adjust, the gas chamber piston pick-up unit of defencive function is arranged.
This Design of device scheme is: a plurality of sensors connect the PLC controller by shielded cable, and the PLC controller is connected with digital display instrument, language alarm and the operation display instrument that shows each sensor information by shielded cable.Sensor and corresponding digital display instrument number are no less than 4.
All measurements of this device, discriminatory analysis are finished by intelligent element entirely, and the error of having avoided human factor to produce has improved this device reliability of operation.Operating personnel can come into plain view to the real-time testing result of piston all directions height in the pulpit.The data response speed is fast, can reach the microsecond level.Easy to adjust rapid, can save time, reduce labour intensity.The operator on duty can directly read the kinds of processes data of gas chamber in the pulpit, having avoided may the on-the-spot injury that the testing staff is caused.The digital demonstration in check point position, the physical location that can observe out all check points easily from digital displaying meter.In case data presentation is unusual, can in time take the adjustment measure, guarantee the gas chamber normal operation effectively.
Four, description of drawings:
Accompanying drawing 1 is this device circuit schematic diagram.
Accompanying drawing 2 is this device and gas chamber connection synoptic diagram.
Five, embodiment:
PLC controller (1) in the accompanying drawing 1 but adopt PLC serialization logic controller, digital display instrument (2) and language alarm (3) adopt commercially available MHJB digital display instrument and YSX-3 language alarm respectively, the Japanese Omron of sensor (4) employing rotary encoder.Operation display instrument (14) adopts Siemens TD200 guidance panel.Sensor (4) is connected with PLC center processor (1) by shielded cable (5), and PLC center processor (1) is connected with digital display instrument (2), language alarm (3) and operation display instrument (14) by shielded cable (6), (7), (15) respectively again.PLC center processor (1), digital display instrument (2) and language alarm (3) and the general assembly of operation display instrument (14) are in switch board (8).In the accompanying drawing 2 in the gas chamber piston (9) edge at air bag (13) top in succession wirerope (10) by the in succession balance bob (12) of outside of pulley (11).The utility model has been installed 8 sensors (4) (only showing 2 among the figure), and each sensor (4) respectively is installed on pulley (11) central shaft.Piston (9) respectively is connected with wirerope (10) at 8 equal equal angles edges.Collect 8 orientation position of piston height by 8 sensors (4), be sent to PLC through shielded cable, through PLC decoding, computing, whether draw parameter that the digital quantity signal of height, piston average height, coal gas capacity of each orientation piston and operation display instrument set PLC in advance relatively reports to the police after relatively, flow to digital display instrument and intelligent sound alarm respectively, show and the audio alert that glistens.
Claims (2)
1. the gas chamber piston position detects and warning device, it is characterized in that: a plurality of sensors (4) connect PLC controller (1) by shielded cable (5), and PLC controller (1) is connected with digital display instrument (2), language alarm and the operation display instrument (14) that shows each sensor (4) information by shielded cable (6), (7), (15).
2. detect and warning device according to the described gas chamber piston position of claim, it is characterized in that: the number of sensor (4) and digital display instrument (2) is no less than 4.
