Problems solved by technology
[0002] At present, the mine drainage system still adopts the local decentralized control of the underground pump room. The operator manually controls the opening and closing of the water pump according to the water level of the underground water tank. One worker looks at one water pump. Generally, there are at least 6 people in each team. The main disadvantages are It is a serious waste of human resources. When a large amount of water gushes suddenly, if the operator fails to monitor well, it is very likely to cause a well flooding accident, and in severe cases, it may cause casualties
And there are many problems that are not suitable for the current drainage monitoring system, such as high labor intensity, complicated operation process, long start and stop time, and low efficiency.

Embodiment Construction
[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0020] A coal mine drainage and automatic water level monitoring alarm system is composed of main and auxiliary drainage systems, an automatic water level monitoring alarm system and a positioning system.
[0021] Among them, the basic structure of the main and auxiliary drainage systems are the same, consisting of the main float pump switch (referred to as the main pump switch) 6, the main contactor 5 and the main pump 8; the auxiliary float pump switch (referred to as the auxiliary pump switch) 7 , The auxiliary contactor 28 and the auxiliary water pump 9 are composed.
[0022] The following takes the main drainage system as an example to describe the system in detail.
[0023] Such as figure 1 As shown, a positioning rule 11 is installed on the positioning rule base 25, and at least one row of positioning holes 21 is opened on the positioning rul...

The invention discloses a coal mine water drainage and automated water level monitoring and alarming system. The coal mine water drainage and automated water level monitoring and alarming system consists of a main water drainage system, a secondary water drainage system, an automated water level monitoring and alarming system and a positioning system, wherein the basic structure of the main water drainage system is the same as that of the secondary water drainage system; the main water drainage system consists of a main float type water pump switch, a main contactor and a main water pump; and the secondary water drainage system consists of a secondary float type water pump switch, a secondary contactor and a secondary water pump. The automated water level monitoring and alarming system consists of a water level monitoring and alarming control system and an audible and visual alarm signal. The positioning system consists of a positioning scale, a main guide line, a secondary guide line and a positioning scale running part, and scales are carved on the outer skins of the main guide line and the secondary guide line. The system is high in degree of automation, and is safe, reliable and stable.
Description
Technical field [0001] The invention belongs to the technical field of coal mine drainage safety, and particularly relates to a coal mine drainage and an automatic water level monitoring alarm system. Background technique [0002] At present, the mine drainage system still adopts the underground pump house for local decentralized control. The operator manually controls the on and off of the pump according to the depth of the underground sump. A worker looks at a pump, and each team usually has at least 6 people. The main drawback is It is a serious waste of human resources. When there is a sudden and large water influx, if the operator does not monitor well, it is very likely to cause a flooding accident, and it may cause casualties in severe cases. And there are many problems that are not suitable for the current drainage monitoring system, such as high labor intensity, complex operation process, long start and stop time, low efficiency and so on. Summary of the invention [000...
