Abstract
The utility model relates to a mine drainage monitoring and protecting device, which is characterized in that the monitoring and protecting device consists of a flow rate and water level sensor, a water pump, a valve, an underground pump room PLC, a ground control PLC and a host monitoring system. Signals of the flow rate and water level sensor arranged on a drainage pipeline are transmitted to the underground pump room PLC via a data line, and then the underground pump room PLC transmits the signals to the ground control PLC to be communicated with the host monitoring system, and simultaneously outputs signals to control the water pump and the valve which are mounted in a pump room via data lines, and the host monitoring system is mounted beside the ground control PLC (4). The mine drainage monitoring and protecting device can meet requirements of controlling mine drainage systems.
Description
Technical field
The utility model relates to a kind of mine electronic product, especially a kind of mine drainage surveillance monitor protective device.
Background technology
At present, Mine Drainage System still adopts the decentralised control on the spot of down-hole pump house, its main drawback is the operative employee according to the water pump platform number of the opening/stop and open of the artificial control of pump of shaft sump water level depth/stop, when sudden a large amount of water burst,, may cause casualties when serious if operating personnel monitor the ineffective well accident of flooding that very likely causes.Therefore, be badly in need of a kind of Mine Drainage System on-line intelligence surveillance monitor device of exploitation, can realize the automation and the intellectuality of Mine Drainage System for mine safety; Can be according to the water pump platform number of the opening/stop and open of the climbing speed automatically controlled water pump of shaft sump water level depth and water level/stop; And can report to the police automatically according to water yield, notify personnel to withdraw early in case of necessity.
The utility model content
The utility model is for solving the ineffective well accident of flooding that very likely causes of existing Mine Drainage System monitoring, and the problem that may cause casualties when serious provides a kind of mine drainage surveillance monitor protective device.
The utility model is to be made of flow and level sensor (1), water pump and valve (2), down-hole pump house PLC (3), Ground Control PLC (4), upper location supervisory (5); Concrete technical scheme of the present utility model is: be arranged on the flow on the discharge pipe line and the signal of level sensor (1) and be sent to down-hole pump house PLC (3) by data wire, down-hole pump house PLC (3) passes the signal to Ground Control PLC (4) and upper location supervisory (5) communication again by data wire, meanwhile output signal is installed in the water pump and the valve (2) of pump house by data wire control, be arranged on the running status that the upper location supervisory (5) of the position of Ground Control PLC (4) next door being convenient to observe can intelligent surveillance monitoring drainage system, down-hole pump house PLC (3) has " automatically " " on the spot ", " maintenance " three kinds of working methods, Ground Control PLC has remote monitoring collection keyholed back plate reason function by data wire; Q=∑ Q is set in PLC inside
nAnd H
/=dH/dt function relation curve; Wherein: Q-total displacement, Q
n-each pump displacement, H
/-water level climbing, the H-water level depth.
The beneficial effects of the utility model: 1, can satisfy the control requirement of mine, native system control accuracy height, safe and reliable to drainage system; 2, can realize the automation and the intellectuality of Mine Drainage System; 3, can be according to the water pump platform number of the opening/stop and open of the climbing speed automatically controlled water pump of shaft sump water level depth and water level/stop; 4, under normal circumstances, can calculate the effective time of every pump and change pump work, to guarantee each pump work time equalization according to this time enforcement; 5, can report to the police automatically according to water yield, notify personnel to withdraw early in case of necessity, to realize the safety of mine, personnel, equipment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the transfer of data route map of this patent
Among the figure, flow and level sensor (1), water pump and valve (2), down-hole pump house PLC (3), Ground Control PLC (4), upper location supervisory (5)
The specific embodiment
As shown in Figure 1, be sent to down-hole pump house PLC (3) by being arranged on the flow on the discharge pipe line and the signal of level sensor (1) by data wire, down-hole pump house PLC (3) passes the signal to Ground Control PLC (4) and upper location supervisory (5) communication again by data wire, meanwhile output signal is installed in the water pump and the valve (2) of pump house by data wire control, be arranged on the running status that the upper location supervisory (5) of the position of Ground Control PLC (4) next door being convenient to observe can intelligent surveillance monitoring drainage system, down-hole pump house PLC (3) has " automatically " " on the spot ", " maintenance " three kinds of working methods, Ground Control PLC has remote monitoring collection keyholed back plate reason function by data wire; Q=∑ Q is set in PLC inside
nAnd H
/=dH/dt function relation curve; Wherein: Q-total displacement, Q
n-each pump displacement, H
/-water level climbing, the H-water level depth.When a certain physical quantity deflection curve moves; can judge fault trend; send the pre-alarm signal in view of the above, this protective device can in time send alarm signal and fault interlocking signal when protecting limit value if fault trend increases the weight of to surpass, and notifies personnel to withdraw in case of necessity.Running status and alarm signal can show on computer screen.
Claims (1)
1. a mine drainage surveillance monitor protective device is to be made of flow and level sensor (1), water pump and valve (2), down-hole pump house PLC (3), Ground Control PLC (4), upper location supervisory (5); It is characterized in that: be sent to down-hole pump house PLC (3) by data wire by being arranged on the flow on the discharge pipe line and the signal of level sensor (1), down-hole pump house PLC (3) passes the signal to Ground Control PLC (4) and upper location supervisory (5) communication again by data wire, meanwhile output signal is controlled water pump and the valve (2) that is installed in pump house by data wire, and upper location supervisory (5) is installed in Ground Control PLC (4) next door.
