Abstract

The invention relates to a mining explosion-proof and intrinsically safe programmable control box for a water pump room, which comprises an explosion-proof main cavity and an explosion-proof wiring cavity. Cable leading-in devices are arranged on the left side, the right side and the lower side of the explosion-proof wiring cavity, and an intelligent key board and a display screen are arranged ona left front door panel of the explosion-proof main cavity. A glass observation window and a function knob are arranged on a right front door panel of the explosion-proof main cavity, a nine-core wiring terminal and a wall penetrating terminal are arranged between the explosion-proof wiring cavity and the explosion-proof main cavity, and a network switch is arranged in the explosion-proof wiring cavity. A transformer, a programmable module group and an anti-surge and filtering module group are arranged in the explosion-proof main cavity, the intrinsic safety power supply, the switching power supply, the anti-surge and filtering module group are respectively connected with the intrinsic safety power supply, and the switching power supply, the programmable module group and the display screenare respectively connected with the network switch through network cables for data exchange. The programmable control box has the advantages of convenient operation, various communication interfaces,strong compatibility, complete functions and stable and reliable connection.

Description

[technical field] [0001] The invention relates to the technical field of programmable control boxes, in particular to a mine flameproof and intrinsically safe programmable control box for water pump houses. [Background technique] [0002] Known, mine explosion-proof programmable control box is used in mines with methane mixed gas and coal dust, and explosion hazard. As the main device of the on-site equipment of the automatic centralized control system of the underground water pump room of the coal mine, the country continues to strengthen the construction of the production automation of the coal mine water pump room, in order to realize the automation, intelligence and informationization of the water pump room system as soon as possible. At present, most mine flameproof programmable control boxes used in water pump rooms on the market have the problems of single function, few cable lead-in devices, and few communication interfaces, which cause inconvenience to users and als...
