Description
Technical field
The utility model relates to the mine safety technical field, relates generally to a kind of water level monitoring system of coal mine underground sump.
Background technology
Run well in order to ensure down-hole central pump house, each exploiting field water plant electromechanical equipment, stipulate that each water bunker level is no more than warning line, so drainage system under coal mine is an important component part of colliery main equipment.If main drainage system can not normally move, the safety in production of the whole mine of entail dangers to, even can cause heavy losses of property accident.Under present most coal mine, main drainage system does not have the monitoring of high-low water level and water pump operation state, is mainly staff's periodical inspection, by its soon, the hand operation conditions of touching to observe water level height and equipment, neither science is also dangerous.Under the water level abnormal condition, the suction hose bottom valve stops up, as could not in time finding, will cause and flood pump, even flood the well accident, not only jeopardize the personal safety of coal miner, but also have a strong impact on the raising of management level and the economic benefit in underground main drainage pump room.
The utility model content
In order to address the above problem, the utility model provides a kind of water level monitoring system of coal mine underground sump, and by detecting the duty of water bunker level and water pump, the operation of rational management unwatering pump, reach timely draining, ensures the equipment of borehole operation and personnel's safety.
The technical solution of the utility model is:
A kind of water level monitoring system of coal mine underground sump, comprise for the water pump of sump draining and the motor of make-up pump work, be provided with the level sensor for detection of its water level in described sump, establish the temperature sensor for detection of its Current Temperatures on water pump and motor, also be provided with the electrical quantity sensor for detection of its working current on described motor input electric wire; Described level sensor, temperature sensor all are connected with the input end of microprocessor with the output terminal of electrical quantity sensor, and the output terminal of described microprocessor is connected with display screen.
The input end of described microprocessor also is connected with for detection of pump switch state of switch sensor.
Described level sensor all is connected with the input end of described microprocessor by amplifying circuit, A/D converter successively with the output terminal of electrical quantity sensor.
The output terminal of described microprocessor is connected with warning device.
Described warning device is hummer.
The utility model has been realized automatic collection and the detection of data, and its automatic data collection and detection mainly are divided into collection and the detection of analog data and switching value data.Analog data mainly contains: water bunker level, motor working current, water pump axle temperature, motor temperature; The data of switching value mainly contain: the start-stop state of water pump.
Chromatic liquid crystal screen is adopted in the dynamic demonstration of system, start-stop state by the figure dynamic display water pump, be presented in real time water pump current value and temperature value on liquid crystal display with numeral, method with filling graph, the form that the height of water bunker level is changed with animation shows in real time intuitively, and shows exactly the height of water level with scale and numeral.The mode that system employing sound, light are reported to the police, when the excessive bearing temperature of water pump, the working current of motor reaches lower bound or high limit, and water level reaches high alarm setting or low alarm limit, the numerical value that system is presented on liquid crystal display is set to red alarm, and by hummer, carries out audible alarm.
The utility model system is by detecting the duty of water bunker level and water pump, 4 water pump operations of rational management.By LCDs in modes such as image, numeral, colors, intuitively, image, reflect the parameters such as working state of system and water bunker level, motor working current, motor temperature, bearing temperature in real time, and in the running status of water pump, automatic alarm and outage when abnormal appear.System has reliable, intelligent degree high, can in time understand easily the operation conditions of water bunker level and water pump, and can save the operating cost of water pump.
Reach simultaneously the real-time detection to coal mine underground sump water level and drainage equipment ruuning situation, and realize the operation of rational management unwatering pump, reach timely draining, ensure the equipment of borehole operation and personnel's safety.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1: the utility model structural principle block diagram.
Embodiment
As shown in Figure 1, a kind of water level monitoring system of coal mine underground sump, comprise for the water pump of sump draining and the motor of make-up pump work, be provided with the level sensor 2 for detection of its water level in described sump, establish the temperature sensor 1 for detection of its Current Temperatures on water pump and motor, also be provided with electrical quantity sensor 3 for detection of its working current on described motor input electric wire, for detection of pump switch state of switch sensor 4; Level sensor 2 all is connected with the input end of microprocessor 6 by amplifying circuit 4, A/D converter 5 successively with the output terminal of electrical quantity sensor 3; Temperature sensor 1 all is connected with the input end of microprocessor 6 with the output terminal of switch sensor 4, and the output terminal of described microprocessor 6 is connected with display screen 7 and hummer 8.
In the utility model, the situations such as the temperature of the temperature of water bunker level, water pump, switch situation and motor, electric weight all show in real time in display screen, and the work people does not need to go to patrol and examine the water level that can grasp coal mine underground sump and the ruuning situation of drainage equipment on the spot.If the working current of the excessive bearing temperature of water pump or motor reaches lower bound or high limit or water bunker level and reaches high alarm setting or low alarm limit, the numerical value that system is presented on display screen is set to red alarm, and by hummer, carries out audible alarm.Allow the staff go in time to process, avoid dangerous and occur.Ensured simultaneously the safe operation of equipment.
