Abstract
A kind of filling operation face surrounding rock failure scope automatic detection device, belongs to the pick-up unit of coal mine work area surrounding rock failure scope.This pick-up unit comprises: ground-based computer, down-hole control substation, flowmeter, pressure transducer, solenoid valve and constant pressure pump; The output terminal that down-hole controls substation is connected with ground-based computer, the input end that flowmeter, pressure transducer control substation with solenoid valve and down-hole is connected, constant pressure pump is connected to filling operation face country rock by pipeline, and described pipeline is connected with flowmeter, pressure transducer and solenoid valve; Ground-based computer controls by down-hole the start and stop that substation controls constant pressure pump.Advantage: this device can detect filling operation face surrounding rock failure scope easily, destructiveness, this pick-up unit, simple to operate, stability is high, easy for installation, signal stabilization, safety, stability is high.Instead of personnel in the pit's manual operation, reduce safety cost, reduce workman's workload, improve mine safety guarantee degree.
Description
Technical field
The utility model relates to a kind of pick-up unit of coal mine work area surrounding rock failure scope, particularly a kind of filling operation face surrounding rock failure scope automatic detection device.
Background technology
At present, the detection of coal mine work area surrounding rock failure scope mainly passes through execute-in-place work at downhole operations.Usually by operative employee's manual control valve on one side, observed pressure table and metered water supply amount are implemented to observe and record, underground work environment severe, bring certain difficulty and error to the collection of data.
Utility model content
The purpose of this utility model to provide a kind of filling operation face surrounding rock failure scope automatic detection device, stable, accurate detection coal mine work area surrounding rock failure scope.
The utility model solves the technical scheme that its technical matters adopts: this pick-up unit comprises: ground-based computer, down-hole control substation, flowmeter, pressure transducer, solenoid valve and constant pressure pump; The output terminal that down-hole controls substation is connected with ground-based computer, the input end that flowmeter, pressure transducer control substation with solenoid valve and down-hole is connected, constant pressure pump is connected to filling operation face country rock by pipeline, and described pipeline is connected with flowmeter, pressure transducer and solenoid valve; Ground-based computer controls by down-hole the start and stop that substation controls constant pressure pump.
Beneficial effect: owing to have employed such scheme, in filling operation face, country rock squeezes into boring, passes into water pipe in boring, and water pipe is supplied water by constant pressure pump, water pipe is installed solenoid valve, pressure transducer, flowmeter, and control signal controls substation by down-hole and imports ground-based computer into.When needs detect, operating personnel control the start and stop of constant pressure pump at ground computing machine by underground substation, open solenoid valve, observe pressure transducer numerical value and flowmeter numerical value simultaneously.Computing machine can the instantaneous delivery of automatic flow meter and integrated flow carry out analyzing and preserving.Destructiveness and the scope of filling operation face country rock can be determined further by the analysis of flow meter.In pressure stability situation, the aggregate-value of continuous observation flowmeter, judges the destructiveness of filling operation face country rock according to integrated flow.The aggregate-value of ground-based computer to flow does to be filed, preserves.
Advantage: this device can detect filling operation face surrounding rock failure scope easily, destructiveness, this pick-up unit, simple to operate, stability is high, to install easily, convenient, signal stabilization, safety; Add the reliability and stability of downhole detection, instead of personnel in the pit's manual operation, reduce safety cost, reduce workman's workload, improve mine safety guarantee degree.
Accompanying drawing explanation
Fig. 1 is installation diagram of the present utility model.
In figure, 1, ground-based computer; 2, down-hole controls substation; 3, flowmeter; 4, pressure transducer; 5, solenoid valve; 6, constant pressure pump; 7, filling operation face country rock.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1: this pick-up unit comprises: ground-based computer 1, down-hole control substation 2, flowmeter 3, pressure transducer 4, solenoid valve 5 and constant pressure pump 6; The output terminal that down-hole controls substation 2 is connected with ground-based computer 1, the input end that flowmeter 3, pressure transducer 4 control substation 2 with solenoid valve 5 and down-hole is connected, constant pressure pump 6 is connected to filling operation face country rock by pipeline, and described pipeline is connected with flowmeter 3, pressure transducer 4 and solenoid valve 5; Ground-based computer 1 controls by down-hole the start and stop that substation 2 controls constant pressure pump 6.Utilize constant pressure pump, solenoid valve, pressure transducer, flowmeter, control substation by down-hole, Signal sampling and processing is transferred to ground, to be processed and analyze, signal stabilization by surface computer system to signal, display accurately.
In the drawings, underground filling work face country rock 7 squeezes into boring, access water pipe, when needing to detect, ground-based computer 1 can control substation 2 by down-hole and open constant pressure pump 6, open water pipe solenoid 5, by computer 1 observed pressure sensor 4 and flowmeter 3, computing machine can the instantaneous delivery of automatic flow meter and integrated flow carry out analyzing and preserving simultaneously.Can be determined destructiveness and the scope of filling operation face country rock further by the analysis of flow meter, the theoretical analysis preventing and ensure the system of making in advance is carried out in the filling for next step.
