Flame-proof and safety type digitisation automatically drain system for mining

Abstract

An explosion-proof and intrinsically safe digital automatic drainage system for mines belongs to the technical field of underground automatic detection in coal mines. The technical scheme of the type digital automatic control system is characterized in that the system is composed of three parts: the intrinsically safe digital water level sensor I, the flameproof and intrinsically safe control circuit II and the intrinsically safe power supply circuit III. It is a set of digital and intelligent monitoring system , with real-time collection and storage of water level signals, monitoring the working status of the pump motor, the flow of the water tank, and real-time control of the start and stop of the motor, realizing the functions of data display, limit alarm and host computer serial communication. It is designed in accordance with the safety standards of the coal mine industry, and the explosion-proof mark is Exdib. It can be widely used in the automatic monitoring of the water level of the underground water tank and the automatic drainage system of general mines and high-gas mines.

Description

1. Technical field [0001] The invention relates to an explosion-proof and intrinsically safe digital automatic drainage system for mines, which belongs to the technical field of underground automatic detection in coal mines, and can be used for automatic monitoring of the water level of underground water tanks in high-gas coal mines and automatic drainage systems. 2. Background technology [0002] Due to the poor production environment in coal mines, mine disasters occur frequently, and the disaster caused by coal mine water damage is one of the three major disasters in coal mines. At present, the drainage of underground water tanks in coal mines is mostly realized by manual control. The reason is that the water in coal mine underground water tanks is coal slime water or accompanied by suspended sewage. At this stage, there is no water level detection technology and automatic drainage system for coal mine underground water tanks. mature product. The "inductive digital water...

Problems solved by technology

At present, the drainage of underground water tanks in coal mines is mostly realized by manual control. The reason is that the water in coal mine underground water tanks is coal slime water or accompanied by suspended sewage. At this stage, there is no water level detection technology and automatic drainage system for coal mine underground water tanks. mature product

The "inductive digital water level sensor (ZL96110735.9)" and "retrieval digital water level sensor (ZL200310109631.9)" invented by Professor Ma Fuchang of Taiyuan University of Technology solved the problem of collecting water level signals in harsh environments and the problem of long-distance signal transmission in culverts. It is a worldwide problem, but the water level detection technology and real-time automatic drainage control of coal mine underground water tanks are still long-awaited problems in the field of coal mine automation. This is related to the safety of coal miners and the loss of economic interests that cannot be counted by the country.
