Automatic drainage system and method

Abstract

The invention provides an automatic drainage system and method, and relates to the technical field of coal mine drainage. The automatic drainage system and method can solve the problems that water in a water sump is not drained timely and overflows frequently or a water pump idles when no water exists in the water sump. The automatic drainage system comprises a water level signal monitoring device arranged in the water sump, a water pump placed in the water sump and a controller electrically connected with the water pump. The controller is connected with the water level signal monitoring device and the water pump; the water level signal monitoring device moves up and down along with the water level in the water sump; the water level signal monitoring device sends a water pump starting and stopping signal to the controller; and the controller controls the water pump to work. The automatic drainage method is based on the automatic drainage system. By adopting the automatic drainage scheme, unattended drainage of all underground temporary drainage points is achieved, manpower resources are saved, and accumulated water is prevented from overflowing.

Description

technical field [0001] The present disclosure relates to the field of coal mine drainage, in particular to an automatic drainage system and method. Background technique [0002] The underground geological conditions of the coal mine are poor and there is a lot of water. In order to discharge the water in the coal mine, a large number of water pumps are required, which leads to a large number of people occupied by the drainage and the water tank is not drained in time and often overflows. [0003] More specifically, because there are many drainage sites in the parking lot under the mine, the management is difficult. During the long-term drainage, it was found that sometimes the water in the tank was full and the pump was too late to start, causing the water to overflow the tank. Sometimes the tank was empty, but the pump was still there. idling. [0004] In view of this, it is necessary to develop an automatic drainage system and method to solve the problem that the water ta...

[0002] The geological conditions of the underground coal mine are poor and there is a lot of water. In order to discharge the water in the coal mine, a large number of water pumps are needed, which leads to a large number of people occupied by the drainage and the drainage of the water tank is not timely and often overflows

[0003] More specifically, because there are many drainage sites in the parking lot under the mine, the management is difficult. During the long-term drainage, it was found that sometimes the water in the tank was full and the pump was too late to start, causing the water to overflow the tank. Sometimes the tank was empty, but the pump was still there. idling

[0004] In view of this, it is necessary to develop an automatic drainage system and method to solve the problem that the water tank often overflows when the water tank is not drained in time or the water pump is idling when the water tank is empty.
