Abstract
The utility model relates to a sensor for an ash dam saturation line of a thermal power plant, comprising a housing. An elastic diaphragm is arranged on the bottom of the housing, and a hall device is arranged inside the housing, and a magnetic steel is arranged on an inner side of the elastic diaphragm, and a gap is left between the magnetic steel and the hall device which is arranged above the magnetic steel, and the magnetic steel can be pasted on the elastic diaphragm, and the hall device is connected to a circuit board inside the housing, and a wire which outputs signal is passed through a top of the housing, and one end of the wire is connected to the circuit board and the other end is exposed outside the housing. When measuring the saturation line in an ash field of the power plant, water produces pressure toward the elastic diaphragm, and distance between the magnetic steel and the hall device is changed by deformation of the elastic diaphragm, and a changed electrical signal is the position where the saturation line is positioned after being calculated. The utility model has the advantages of simple structure, corrosion resistance and impact resistance, which can work long in a high pH value condition.
Description
Technical field
The utility model relates to a kind of generating plant saturation sensor, especially can be under high pH value condition the generating plant saturation sensor of operate as normal.
Background technology
Coal ash after the burning of fuel-burning power plant connects water band ash by pipeline and delivers to storage ash field.The storage ash fences up with dam around the field, is equivalent to a reservoir.Whether dam is just estimated saturation safely.
At present, the monitoring of the saturation of fuel-burning power plant is manually to use ruler measurement, can not accurately and timely pinpoint the problems, and manually can't go to the scene when especially raining heavily, and it is that pH value is too high that sensor in the past can not adapt to the water coal ash reason of discharging the generating plant.
Summary of the invention
Can not satisfy fuel-burning power plant saturation monitoring problem in order to overcome existing sensors, the utility model provides a kind of novel sensor.The corrosion that this sensor energy and computer networking are monitored saturation automatically and can be resisted the high concentration pH value.
The technical scheme that its technical matters that solves the utility model adopts is: ash dam, a kind of fuel-burning power plant saturation sensor, comprise shell, the bottom of described shell is equipped with flexible sheet, inside is equipped with hall device, described flexible sheet installed inside has magnet steel, and described magnet steel is with leaving the gap between the described hall device.
Described hall device can be positioned at described magnet steel top.
Described magnet steel Pasting is on flexible sheet.
Described hall device connects the circuit board that is positioned at shell, and the lead that is used for output signal passes described cover top portion, and an end connects described circuit board, and the other end is exposed at described enclosure.
Connect by being connected lead between described hall device and the described circuit board.
Described cover top portion is a gland bonnet.
Principle of work of the present utility model is: in sensor is placed on piezometric tube, when coal ash water is arranged in the pipe, water produces pressure to sensor diaphragm, impel the diaphragm modification, change distance between magnet steel and the hall device after the diaphragm modification, hall device is exactly the saturation position with the electric signal of this variation through calculating.Because flexible sheet and Hall all are linear, so sensor output signal also is linear.Guaranteed the accuracy of Monitoring Data.Diaphragm itself is special resistant material, so can resist the too high influence that causes of pH value.
The beneficial effects of the utility model are: simple in structure, corrosion-resistant, shock-resistant, and can long-term work under high pH value condition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, total system all seals, described flexible sheet 1 is installed in the bottom of described shell 2, described gland bonnet 8 is installed at the top, in described flexible sheet 1 the inside described magnet steel 3 is installed, described hall device 4 is installed directly over described magnet steel 3, described circuit board 6 is installed in described hall device 4 tops, and by described connection lead 5 described hall device 4 of connection and described circuit boards 6, the described circuit board 6 external described leads 7 that are used for output signal are exported signal by the described lead 7 that is used for output signal.
(by the water depth decision) generation distortion has changed the distance between described magnet steel 3 and the described hall device 4 thus when described flexible sheet 1 is subjected to the pressure of water, and magnetic field changes and changes electric signal output into.
