Abstract
The utility model discloses an explosion insulation and intrinsic safety type monitoring substation for mining and relates to a mining monitoring device. The substation comprises a box body which is an explosion insulation type box body and provided with an explosion insulation cavity and an intrinsic safety cavity, wherein the explosion insulation cavity and the intrinsic safety cavity are connected with each other. A power circuit is installed inside the explosion insulation cavity, a data acquisition and storage device is installed inside the intrinsic safety cavity, and an upper cover is arranged at the top of the intrinsic safety cavity. The power circuit comprises a switching power supply, a storage battery, a JQ1P-5 volt relay and two 18 volt converting to 12 volt circuit boards, and the switching power supply, the storage battery, the JQ1P-5 volt relay and the two 18 volt converting to 12 volt circuit boards are sequentially connected. The data acquisition and storage device comprises a central processing unit (CPU), wherein the CPU is connected with a network interface, four controlling output modules, eight current input modules and eight frequency input modules. Voltage of 12 volts is output by the power circuit arranged inside the explosion insulation cavity to supply electricity to the data acquisition and storage device inside the intrinsic safety cavity. The explosion insulation and intrinsic safety type monitoring substation for the mining has the advantages that the box body is of an explosion insulation type and provided with the independent explosion insulation cavity and an independent wiring connecting cavity, input and output of an interior circuit are protected through a circuit, and a function of explosion insulation is achieved.
