Abrégé

Disclosed is an underground deep automated spiral drainage apparatus, comprising: a drainage control system and an underground drainage system. The drainage control system comprises an upper computer, a lower computer, and a local control module; the upper computer comprises multiple groups of industrial control computer equipment; the local control module comprises a local control box, a control substation, and instrument equipment. The underground drainage system comprises underground drainage equipment and an underground pump house. The communication between the underground drainage system and the control substation is achieved by means of optical cable communication. The drainage apparatus has the advantages of saving energy and reducing the labor intensity of workers, and achieves an unattended and automated drainage function of the drainage pump house; in response to the national call for energy conservation and consumption reduction, PLC control is used to effectively control a power consumption period of motor operation according to the energy conservation requirements in the premise that the requirements of safe drainage are satisfied; automatic start-up and manual start-up can be achieved. Manual operation is available when a PLC fails.
