Description
Technical field
The utility model relates to a kind of mining PLC control cubicle, relates in particular to a kind of modularization Flameproof intrinsically safe PLC control cubicle that is used for subsurface environment.
Background technology
At present, in the coal in China industry, generally adopt PLC as the various electric equipments of industry control component controls.In use, PLC is arranged in the cabinet-shaped casing usually, and this cabinet-shaped casing can be referred to as the PLC control cubicle.Common PLC control cubicle structure is single, and the expansion difficulty when needs increase the quantity of control appliance or revise control logic, need be taken the control cubicle operation apart, considers the environment of down-hole, and the workload of this work is very big.Especially when system need increase other control module, do not have the space of redundancy to lay in the control cubicle, just make to redesign and the replacing control cubicle that this has just brought huge waste owing to have now.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of mining PLC control cubicle, comprise: cabinet, described cabinet has central dividing plate, cabinet inside is divided into main chamber and wire connection cavity, have a plurality of installation units in the described main chamber and be used to hold electric component, have a plurality of through holes on the described central dividing plate, be used to be communicated with main chamber and wire connection cavity.
Be provided with dividing plate in the wherein said wire connection cavity, described dividing plate is divided into intrinsic safety wire connection cavity and explosion insulation connecting line cavity with described wire connection cavity.
Wherein said main chamber is divided into a plurality of mounting layers, but being arranged in each mounting layer of described installation unit pull.
The size of wherein said installation unit is adjustable.
Wherein said main chamber has main chamber's door, and described wire connection cavity has the wire connection cavity door.
Wherein said main chamber door is provided with display screen, and described wire connection cavity door is provided with keyboard.
Wherein the cabinet arranged outside near wire connection cavity has binding post, and described binding post comprises heavily loaded connector.。
Advantage of the present utility model is:
1. main chamber and wire connection cavity are isolated, and it is more convenient to connect up, and increases work efficiency;
2. installation unit modularization, big or small position is all adjustable, helps function expansion and maintenance;
3. main chamber is divided into a plurality of mounting layers, and each functional module can be concentrated setting relatively, but the setting of installation unit pull carry in each mounting layer, be convenient to installation, maintenance and patrol and examine;
4. the external cabling terminal adopts heavily loaded connector, is convenient to quick grafting;
5. integrated explosion proof system design can be used in than rugged environment in the down-hole.
Description of drawings

Embodiment
Referring to accompanying drawing 1-3, a kind of mining PLC control cubicle, comprise: cabinet, described cabinet has a central dividing plate, central dividing plate is divided into main chamber and two spaces of wire connection cavity with cabinet inside, be divided into 4 mounting layers in the main chamber, have a plurality of installation units in each mounting layer, the quantity of installation unit can be set arbitrarily in mounting layer and every layer, but installation unit is arranged in each mounting layer by tongue-and-groove cooperation or alternate manner pull, in the installation unit electric component can be set, as PLC, various terminals etc., the lead-in wire of electric component enters wire connection cavity by the through hole on the central dividing plate in the main chamber.The size of above-mentioned installation unit can be designed as adjustable, can by structural design or for example use plugboard etc. similarly parts realize its controllability, like this, same control cubicle just can satisfy the needs of multiple different size electric component placement.
In the wire connection cavity dividing plate can be set, dividing plate is divided into intrinsic safety wire connection cavity and explosion insulation connecting line cavity with wire connection cavity, by the different structure setting in two chambeies, satisfy the needs that different electric components connect, cabinet arranged outside near wire connection cavity has binding post, binding post can connect the lead of drawing by an end from the through hole of central dividing plate, the other end connects device and the equipment that needs control.Described binding post is quick grafting binding post, comprises heavily loaded connector, can realize reaching in a large number the installation in advance of complicated circuit, can greatly improve the equipment installation effectiveness, reduces the wiring error rate; Realize the modular construction of each functional template piece of equipment conveniently, efficiently, the equipment that makes can carry out transportation, installation, maintenance and maintenance easily and safely; Provide high integration to connect, abundant compound mode has at utmost improved the effective rate of utilization of the device space.
Be security consideration, described main chamber is provided with main chamber's door, and described wire connection cavity is provided with the wire connection cavity door, on main chamber's door display screen is set, on the wire connection cavity door keyboard is set, the running parameter of control cubicle can be set by keyboard, and the operating state and the ruuning situation that show by display screen.
The above; it only is the preferable embodiment of the utility model patent; but the protection range of the utility model patent is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model patent discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of this patent.
