Background technology
Along with constantly mentioning of China's industrial automation level, the engineering automation control appliance that every profession and trade is used is towards safe, reliable, efficient, intelligent direction development.Industry-by-industry is because self industry also all has different requirements to Engineering Control equipment.The colliery industry is the explosion-proof industry of a national class, therefore on control, electromechanical integration equipment very high industry requirement of explosion proof is arranged.Many Engineering Control equipment that the colliery industry is used are now continued to use traditional retrospective installation mostly, and all there is more problem in old-fashioned control appliance aspect soft, hardware facility, and subject matter has: volume is big, heavy, be difficult for installing.
Existing colliery is with flame-proof valve valve electric device control cabinet, and it is few that its introducing device is introduced inlet, can not realize that multiple signals introduce/draw control; The integral body control of control cabinet belongs to the relay control mode, control voltage height, dangerous, and reliability is lower; Do not match with the interface of the automated system in modern times, be unfavorable for improving the whole enterprise automatic control level; In system monitoring, system protection and valve safeguard protection application facet, technical perfect not to the utmost; The valve opening display precision is not high, and the no signal lead-out terminal can't be delivered to central control room with position signalling; Difficulty is installed, causes motor rollback corruption plant equipment and valve easily.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of colliery with flame-proof valve valve electric device control cabinet, make it can obtain multinomial feedback signal in the control cabinet simultaneously, and can control many mining electric device for valve.
In order to overcome the defective that exists in the background technology, the utility model is that the technical scheme that its technical problem of solution is adopted is: a kind of colliery flame-proof valve valve electric device control cabinet, comprise casing, case lid, case lid is provided with in order to display window that shows digital aperture and on-the-spot running status and the diverter switch that is used to switch scene/distant place operating state, it is characterized in that: three cover control device are set in the casing, and this control device comprises circuit module.
The input of described display window is connected with the output of position feedback circuit, and its output also is connected with the signal receiving end of central control room.
The modular circuit that is connected with described diverter switch at the scene/all adopted photoelectricity to isolate anti-jamming circuit in the distant place, input/output circuitry.
The interface kit of described control cabinet and DCS system and employing module controls drive.
Beneficial effect: the utility model can connect many external equipments simultaneously, and it is little to have solved on-the-spot arrangement, can not hold the problem of many control cabinets; Reliability, the stability of circuit working in the control cabinet have been strengthened; Realized central centralized control; Profile is littler, and weight is lighter, simple and reasonable for structure, safety, easy operating, is convenient to install.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a right view of the present utility model.
Among the figure: 1 is that casing, 2 is that case lid, 3 is that chamber door electromechanical interlocking device, 3-1 are that isolating switch handle, 4 is that introducing device, 5 is that display window, 6 is a diverter switch for interlocking scram button, 3-2.
Embodiment
The flame-proof valve valve electric device control cabinet of a kind of colliery as shown in Figure 1 and Figure 2; comprise casing 1, case lid 2; casing 1 is provided with the chamber door electromechanical interlocking device 3 that is used for machinery and electric part interlocking; chamber door electromechanical interlocking device 3 comprises interlocking scram button 3-1 and isolating switch handle 3-2; when needs are opened casing 2; press interlocking scram button 3-1; the isolating switch handle 3-2 of leaving behind; could open case lid 2 by handle; this moment, control cabinet was in the power-failure protecting state; handling safety, explosion-proof coefficient height.After inspection finishes, close upper box lid 2, push to isolating switch handle 3-2, press interlocking scram button 3-1 again and can send.Interlocking scram button 3-1 and isolating switch handle 3-2 are auxiliary facility, the supporting operation of palpus, otherwise can't open case lid 2.Case lid 2 is provided with the diverter switch 6 that is used to switch scene/distant place operating state, when personnel need to carry out control operation at the scene, stirring diverter switch 6 to work on the spot state can operate, when needs distant place master control room carries out control operation, only need stir diverter switch 6 afield operating state get final product, or directly carry out the operating state switching by master control room.Case lid 2 is provided with the display window 5 in order to show digital aperture and on-the-spot running status, aperture shows directly reads aperture percentage, cancelled unnecessary digital scale, the light-emitting component of the running LED on the display window 5 adopts light-emitting diode, therefore the heat that produces during lumination of light emitting diode is very little, helps explosion-proof like this.
Be connected with the output of position feedback circuit in order to the display window 5 that shows digital aperture and on-the-spot running status, this output also is connected with the signal receiving end of central control room.Aperture shows the employing digital display circuit, make the aperture of valve more simple and clear, increased the feedback signal of valve opening position on this basis, make central centralized control the same with field control convenient directly perceived, be convenient to realize on-the-spot unattended duty, the central controlled realization in a distant place.
Owing to adopted module controls, and input signal source is a voltage signal, be to strengthen interference free performance, module at the scene/all adopted photoelectricity isolation, anti-interference short circuit in the distant place, input/output circuitry, strengthened reliability, the stability of circuit working.
Newly-designed control cabinet has been paid attention to the interface kit with the DCS system, in control, adopt module controls to drive, and control voltage has adopted the unified interface voltage DC24V control that is connected mutually with the DCS system, thereby realized the uniformity of control interface butt joint, interface can adopt this confession of passive touch point control power supply, also can adopt DC24V long pulse, short pulse control, it supplies the control power supply.Two kinds of interface control modes make interface circuit more flexible, be convenient to the system convergence with DCS, and field control button and travel switch electric pressure are DC5V voltage, make complete machine control voltage all in safe voltage, make debugging, overhaul safer.
Introduce/draw control, monitoring and connect power supply for realizing multiple signals, introducing device 4 is designed to multichannel and draws outlet on the casing 1, make the introducing/output of control signal, each Kong Yigen cable, the reliability of having strengthened the introducing device sealing makes the explosion-proof performance of control cabinet more reliable.
In indoor design in order effectively to utilize the space of flame proof control cabinet, dwindle, alleviate the volume and the weight of control cabinet, internal module has adopted the building blocks Combination Design, makes control cabinet in operation, more perfect on the layout, makes it simple and reasonable for structure, safety, easy operating, is convenient to install.
