The digital measuring system comprises an insulating hard circular sealing sheath extending into the well, wherein a temperature sensor and double probes are sealed in the insulating hard circular sheath, the temperature sensor is connected with a microcontroller arranged above the well through a conducting wire, one of the double probes is connected with a pulse generator arranged above the well, and the other probe is connected with a pulse detector arranged above the well; a cable is connected on the outside of the insulating hard circular sealing sheath, the other end of the cable is connected on a winch, a displacement sensor is arranged outside the winch, and the displacement sensor is connected with a length counter; and the pulse generator, the pulse detector and the length counter are respectively connected with the microcontroller, and the microcontroller is respectively connected with a computer and a buzzer. According to the digital measuring system, the probes and the sensor extending into the well are well protected by the insulating hard circular sealing sheath, the depth and temperature of water surface in the well can be accurately measured by the rotating the winch, the temperature at different depths in the well can be measured at the same time, and the digital measuring system is convenient, fast and accurate.
Description
Technical field
The utility model belongs to underground heat field monitoring technology, particularly a kind of geothermal well water level-temperature digital measuring system.
Background technology
Traditional on-the-spot water level measurement system can not satisfy the measurement of the geothermal well water level of various operating modes both at home and abroad,
1. the principle of traditional geothermal well water level measurement system is: the break-make of observing DC current with reometer; One utmost point connects the geothermal well borehole wall, and another is survey line very; When the utmost point of survey line touches the water surface, during the change of reometer indicator, artificially observe wire length, this length is water level value.Adopt such one pole to roll off the production line and dc current measurement, and because this time line electrode and geothermal well tube wall (the underground heat well surveying pipe degree of depth>during 100m, survey is managed and is bending) be easy to the contacting metal tube wall, cause the erroneous judgement water level value; Adopt the direct current measurement principle simultaneously, electrode polarizes easily, also can cause and measure erroneous judgement.
2. the geothermal well water level value of traditional geothermal well water level measurement system is owing to be that the variation of survey crew indirect observation reometer draws, the data poor accuracy, and waterlevel data needs manual record simultaneously.
3. traditional geothermal well water level measurement system does not contain the measurement of geothermal fluid temperature; Therefore survey crew needs twice work of rolling off the production line; Could accomplish the water level and the water temperature work of measuring geothermal well; The geothermal fluid temperature value is also drawn by survey crew observation, so the geothermal fluid temperature data also needs manual record.
The utility model content
The utility model technical matters to be solved is: a kind of geothermal well water level-temperature digital measuring system is provided.
1. (observe the break-make of DC current with reometer to the defective of traditional geothermal well water level measurement system principle; One utmost point connects the geothermal well borehole wall, and another is survey line very; When the utmost point of survey line touches the water surface, during the change of reometer indicator, artificially observe wire length, this length is water level value.Adopt such one pole to roll off the production line and dc current measurement, because this time line electrode and geothermal well tube wall (the underground heat well surveying pipe degree of depth>100m, survey pipe and be bending) be easy to the contacting metal tube wall, cause the erroneous judgement water level value; Adopt the direct current measurement principle simultaneously, electrode polarizes easily; Also can cause and measure erroneous judgement.) development is a kind of includes two open insulating rigid circular jacket of probe as level measuring sensor (see figure 1), has avoided contacting of time line electrode and geothermal well tube wall knee; Development zero-crossing pulse source and pulse potential detection module, when including pair open insulating rigid circular jacket of probe and contact with the water surface as the level measuring sensor, the pulse detection module can receive pulsating wave through survey line, sends the signal that touches the water surface.The Another reason in development zero-crossing pulse source is to prevent the polarization of electrode phenomenon, makes to measure the high sensitivity of sensor-based system maintenance.
To the water level value of traditional geothermal well water level measurement system owing to be that the variation of survey crew indirect observation reometer draws, the data poor accuracy, waterlevel data needs the defective of manual record simultaneously.The interface controller of development electronic off-line length counter, level sensor and waterlevel data transmission mouth, the waterlevel data library software, data-base recording comprises: measure date, time, geothermal well pound sign and title, water level value.
3. do not contain the measurement of geothermal fluid temperature to traditional geothermal well water level measurement system; Therefore survey crew needs twice work of rolling off the production line; Could accomplish the water level and the water temperature work of measuring geothermal well; The geothermal fluid temperature value is also drawn by survey crew observation, so the geothermal fluid temperature data also needs the defective of manual record.The temperature probe of army's grade is installed in development additional on same water level survey line; The interface controller of development temperature probe and temperature measurement data transmission mouth; Geothermal well coolant-temperature gage database software; Data-base recording comprises: measurement date, time, geothermal well pound sign and title,, geothermal well coolant-temperature gage value.
3. convenient in order to measure; Develop a kind of buzz module that links to each other with the measuring system controller; So that survey crew need not visualizer dial plate (traditional measurement mechanism is a reometer) in the line process down, when sensor touched the water surface, hummer quit work; Prompting the personnel of rolling off the production line stop to roll off the production line, and all the other work such as the data acquisition of water level and water temperature, data-base recording are accomplished by system automatically.
The technical scheme of the utility model is:
A kind of geothermal well water level-temperature digital measuring system; It is characterized in that: an insulating rigid circular seal sheath that stretches in the well is arranged; It is sealed in has temperature sensor and two probes in the insulating rigid circular jacket; Temperature sensor is through the microcontroller on the lead connection well, the pulse producer on probe connection well of its pair probe, the pulse detector on another probe connection well; The outer connection cable of insulating rigid circular seal sheath, the hawser other end is connected on the capstan winch, capstan winch peripheral hardware set displacement sensor, displacement transducer connects length counter; Pulse producer, pulse detector and length counter are connected microcontroller respectively, and microcontroller connects computing machine, and microcontroller connects hummer.
The utility model effect is:
Because an insulating rigid circular seal sheath that stretches in the well is arranged, the detector and the sensor of down-hole stretched in protection well, guarantees to survey accurately.Native system rotates the interior water surface degree of depth of measuring well exactly, temperature through capstan winch.But the temperature of different depth in the while measuring well.Convenient, fast, accurate.
