Abstract
The utility model discloses a mining water level warning device, the utility model discloses a PLC controller is connected respectively to PLC controller, level sensor, alarm, display and power, level sensor, alarm, display and power, and level sensor is used for detecting the water level of the pump nest of mine sump. The utility model discloses can realize reporting to the police to the water level of mine sump, can realize that the high water level is reported to the police and the low water level is reported to the police. The high water level is reported to the police and is realized carrying out safe warning to personnel when high warning water level, and the low water level is reported to the police and is realized reminding the timely termination of pumping of personnel at low warning water level to damage the water pump rapidly.
Description
Technical field
The utility model relates to a kind of mining water level warning device.
Background technology
At present, mine main drain pump does not also install automation control system, and its control system is only high-voltage switch gear cabinet system, there is not water level alarm system, easily maybe following major accident may occur:
A) the high water stage turn on pump and cause flooding well not in time that occurs of human factor.
B) human factor occur low-water level not in time termination of pumping and cause burn pump.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of mining water level warning device that can improve mine sump security.
In order to solve the problems of the technologies described above, the utility model comprises PLC, level sensor, alarm, display and power supply, level sensor, alarm, display are connected PLC respectively with power supply, and level sensor is for detecting the water level of the pump nest of mine sump.
In order to improve the accuracy of detection, described level sensor adopts diffuse si piezoresistive transducer, and described level sensor has multiple, and multiple level sensor is respectively used to detect different pump nest water levels.
In order to improve security, described power supply is Flameproof and intrinsically safe D.C. regulated power supply, be provided with isolation safe grid between described level sensor and PLC and between display and PLC, between described alarm and PLC, be provided with isolation safe circuit.
In order to easy to connect, the isolation safe grid arranged between described display and PLC adopt RS-485 communication interface.
In order to better remind operating personnel, described alarm comprises phonetic alarm and light crossing-signal, and light crossing-signal includes the alarm lamp of three kinds of colors, and the light visual range of alarm lamp is not less than 50m, and the water level detecting scope of level sensor is 0-10m.
In order to can according to the running status of water auto-regulation water pump, the utility model also includes water pump control module, and water pump control module connects PLC.
The beneficial effects of the utility model are: the utility model can realize reporting to the police to the water level of mine sump, can realize high water-level alarm and low-water alarm.High water-level alarm realizes carrying out safety prompt function when high warning line to personnel, and low-water alarm realizes reminding the timely termination of pumping of personnel, in order to avoid damage water pump rapidly in low warning line.Application of the present utility model makes mine main drain pump control system more perfect, it is made to run more reliable, Be very effective, stopped the water pump serious accident that height warning line turn on pump that human factor causes causes not in time, the safety in production for mine has the meaning of outbalance.
Accompanying drawing explanation
Fig. 1 is control principle drawing of the present utility model.
Embodiment
Specific embodiment as shown in Figure 1, it comprises PLC, four level sensors, phonetic alarm, light crossing-signal, display and Flameproof and intrinsically safe D.C. regulated power supplies.In use, power input voltage: AC127V, supply voltage allowable fluctuation range: 95V-140V, electric power output voltage DC12V.
Level sensor adopts diffuse si piezoresistive transducer, and four level sensors are respectively used to detect different pump nest water levels, and during use, four level sensors are arranged in four pump nests respectively.All level sensors connect PLC by isolation safe grid.The water level detecting scope of level sensor is 0-10m.
Display connects PLC by isolation safe grid, and the isolation safe grid arranged between display and PLC adopt RS-485 communication interface.
Light crossing-signal includes the alarm lamp of red, yellow, and green three kinds of colors, and the light visual range of alarm lamp is not less than 50m(under clog-free condition), light crossing-signal is connected PLC with phonetic alarm by isolation safe circuit.Time of fire alarming can be set by PLC, preferably within the scope of 1min ~ 30min; The chimes of doom loudness of phonetic alarm can be provided with and be not less than 85dB (A).
Be provided with isolation safe grid between described level sensor and PLC and between display and PLC, between described alarm and PLC, be provided with isolation safe circuit.
Principle of work:
Detection signal for detecting the water level of respective pump nest, and is passed to PLC by level sensor, and PLC exports corresponding control signal according to water level conditions to display and alarm.
(1) when pump nest water level exceedes capping, blinking red lamp also sends the chimes of doom of " ## pump nest water level surpasses the upper limit, woulds you please draining ".
(2) when pump nest water level is lower in limited time lower than setting, amber light glimmers and sends the chimes of doom of " ## pump nest water level surpasses lower limit, stops draining ".
(3), when water level does not transfinite, green light, without audio alert.
(4) when more than 2 or 2 pump nest overload alarms, phonetic alarm circulation is reported to the police, and alarm time interval can set.
Claims (5)
1. a mining water level warning device, it is characterized in that: comprise PLC, level sensor, alarm, display and power supply, level sensor, alarm, display are connected PLC respectively with power supply, level sensor is for detecting the water level of the pump nest of mine sump, described alarm comprises phonetic alarm and light crossing-signal, light crossing-signal includes the alarm lamp of three kinds of colors, the light visual range of alarm lamp is not less than 50m, and the water level detecting scope of level sensor is 0-10m.
2. mining water level warning device according to claim 1, is characterized in that: described level sensor adopts diffuse si piezoresistive transducer, and described level sensor has multiple, and multiple level sensor is respectively used to detect different pump nest water levels.
