Specifically, this measuring instrument 1 comprises that 12,1 of sleeve portion that are used to receive data recorder 5 is used for intermediate casing part 3 and 1 pressure survey sleeve portion 4 that is used to receive pressure measurement range 7 of receiving sensor unit 6.Sleeve portion 2 has one and the intermediate casing part 3 lower limb 9 similar terminals at oneself at oneself lower limb 8, make pressure survey sleeve portion 4 promptly can be installed on the lower limb 8 of the sleeve portion 2 that has received data recorder 5, also can be installed on the lower limb 9 of the intermediate casing part 3 that has received sensor unit 6.
Data recorder sleeve pipe 2 it and on the cable of outwards drawing connects together the top loaded onto a top and loaded onto a terminal cap 11; this cap is seated on the coboundary 10 of the sleeve portion 2 that has received data recorder 5, and provides reliable protection by a seal 14 for preventing that liquid from immersing.Seal 14 has two sealing sockets 12 and 13.They have been filled out O-shape ring respectively and have from then on been played the close effect of necessary envelope.Exist an insert 15 in the centre of seal 14, be used to install and outwards draw, at this cable that does not draw.This cable is on the one hand as data conductor, on the other hand as the power supply suppling wire of measuring instrument 1.
Cable can be with instrument casting together, with the reduction expense with play tight effect, perhaps also can insert wherein as situation about pointing out at this, makes cable different length can according to circumstances be installed and exchange each other.The power supply supply very practicably is in the outside of measuring instrument, can be used as power brick and together drops under the face of land, and the situation of measuring instrument that sinks to water level pipe when coexisting subsurface water measurement is the same.
1 prolongation that is positioned at lower limb 8 is arranged in order to assembling intermediate casing part 3 and pressure survey cannula portion 4 on the scope side of avoiding plug 15 of the sleeve portion 2 that has received data recorder 5.The connection of each sleeve portion is such as finishing by a screw thread, each sleeve portion must be reversed when mounted relatively, perhaps by a fixture, each sleeve portion is stayed on the fixture to stationkeeping each other, such as female or other form of being familiar with, a plurality of tube sections are fixed with each other by a thumb screw.
Because instrument often is used in and measures the channel of ground water diameter is in 2 ' the water level pipe, thus be necessary to allow the outer dia of measuring instrument as much as possible little, and in joint sleeve part 2,3 with considered this point at 4 o'clock.
The external thread 17 that pressure survey sleeve portion 4 is expressed 1 internal thread 21 it and intermediate casing part 3 is in the top installed and has been connected intermediate casing part 3.Pressure survey sleeve pipe 4 connects together with the sleeve portion 2 that has received data recorder 5 through the external thread 8 ' of sleeve portion 2.
In addition, pressure survey sleeve portion 4 demonstrates an outlet 22 in its bottom surface, by this outlet medium and the pressure measurement range 7 that should measure are got in touch.
Illustrated at Fig. 6, pressure measurement range 7 is how to be assembled in 4 li of pressure survey sleeve portions and how directly to link together with the sleeve portion 2 around data recorder 5.The internal thread 21 of sleeve pipe aspect pressure survey sleeve portion 4 is tightened with the external threads 8 ' that received the sleeve portion 2 of data recorder, and the pressure measurement range 7 in the sleeve pipe is pressed into a hermetic unit 29 similar to the seal 14 that is positioned at measuring instrument 1 top with its flange 26.Sealing wherein is guaranteed by the O-shape ring that is positioned in sealing socket 27 and 28.The wall one side that hermetic unit 29 faces sleeve portion 2 is to play waterproof effect by the O-shape ring that is positioned at sealing socket 30 and 31 equally.For the length that stops hermetic unit 29 to slip, in the installed inside of sleeve portion 2 one apart from bobbin 32, its side is with the lower end of data recorder 5, opposite side is tightened respectively with hermetic unit 29, to such an extent as to no matter be, or hermetic unit 29 or pressure measurement range 7 all has fixing seat in sleeve pipe separately apart from bobbin 32.Hermetic unit 29 directly can certainly be supported in the lower end of data recorder 5 and dwindle dangling of sleeve portion 2.
A MIN measuring instrument has been described in one as the arrangement introduced in Fig. 6, wherein in pressure survey sleeve portion 4 hygrosensor can also be installed extraly.In addition, can not in this arrangement, be equipped with other sensor.A pure broken floodometer is provided thus, its relative price advantage and very little casing size CS have been arranged.
For such floodometer is changed into a multiduty measuring instrument, at first back out pressure survey sleeve portion 4, then take off pressure measurement range 7 and its flange 26 from the extruding seat, take out hermetic unit 29 and apart from bobbin 32, make the measuring appliance part of a top, describe as Fig. 2, for the part that receives other is used.The sensor unit 6 of downside is inserted in the sleeve portion 2, thereby and connects the other socket of installing of the data recorder that coexists with oneself socket and coincide and guarantee the connection of sensor battery 6.The pressure measurement range 4 of lower end is inserted into one 34 li of the other receivers of casting shape of sensor battery 6 by means of its flange 26, describes as Fig. 7.It is to finish by introduce in the tubule of sensor unit 6 36 cable waterproofly that the electricity of pressure measurement range 4 is connected.Cable can be through a central socket that does not mark separately when carrying out the instrument reconstruction.
Inserting sensor unit 6 that motion injects data recorder lower end socket by one, to have reached sleeve portion 2 by two O-shapes rings in sealing socket 37 and 38 waterproof in the effect of data recorder.Sensor unit 6 is independent of intermediate casing part 3 and is mounted.The measuring instrument that is in the reconstruction of Fig. 7 is intactly surrounded by intermediate casing part 3 and pressure survey sleeve portion 4 in Fig. 1.
Sensor unit is introduced at Fig. 8 particularly 6.It consists essentially of at least one object 38.It supports sensor 39 waterproofly and is fitted into sleeve portion 2 by its outside seal seat 36 and 37 waterproofly.Settled one on the object 38 apart from pin 40, it has played the effect of baffle plate when sensor unit 6 inserts data recorder 5 lower ends.
It mainly is assembly dimerous that those independent sensors 39 demonstrate one.It can make original potential electrode 42 break away from a bobbin 43 around its neck, thereby can change potential electrode 42.Bobbin 43 has window 45 in its neck scope, it makes towards the passage of electrode 42 power supplys and becomes possibility, and helps the intermediate space between bobbin 43 and potential electrode 42 to inject sealing and support ointment.Potential electrode 42 is not only waterproof but also supported abreast in bobbin 43 like this.For distributing sealing better and supporting ointment, an inlet 45 ' has been installed in the side.In addition, the effect of window 45 also is, takes out sealing block once more, and is in medium admission impact electrode 42 under the pressure and the intermediate space between the bobbin 43 through window 45 usefulness, thereby drive sealing block out of, get ready for bobbin 43 receives new potential electrode 42.
After new potential electrode 42 is placed in bobbin 43, should be at first before inserting sealing block the electronics resistance welding of bobbin 42 be received on continuous group 33 ' of socket 33 by window 45 by window 45.Just there is no need to destroy whole sensor 39 after use by this method of work, only need use several weeks such as PH-acidity value measured sensor, but those are more expensive, major part directly comes into operation once more for the bobbin of metal.
Bobbin 43 makes sensor 39 waterproof in the object 38 of sensor unit 6 by the O-type ring that is placed in sealing socket 46 and 47, thereby has accomplished do not have liquid can flow into plug junction 33.
Individual other sensor 39 can also be equipped with a temperature survey extraly, and it only causes a very little additional expense, has special hope to be easy to be met.
For the use that makes sensor 39 has big as far as possible dirigibility, a storage chip can be installed in the scope of the window 45 of bobbin 43.It not only passes to data recorder the form of sensor and with the parameter that it should be measured at every turn, and successively win the operation calibration data.These data were passed to data recorder 5 and by it each measured value are sorted out as correcting the factor before the beginning of a measurement series, so just saved the necessity of calibrating on the spot.In addition, insert or newly add sensor 39 in changing of data recorder 5 and just need not to carry out any change one and comprise software.
For helping special accurate measurement, the influence each other that data recorder 5 can the recognition system state parameter and correct consequent measurement mistake, such as, thereby the too high density that can change of the nitrate content in the underground water changes measured pressure.Because the data that produced by gaging pressure have just hinted the up-set condition of water, so the correction factor that is adapted to high nitrate content has been installed.
If those concrete sensors 39 are not to be connected with data recorder 5 through socket 33, thereby but measurement data is united device through an inductance contactlessly transmits, it will more have advantage.Like this, data recorder is sent a carrier wave.The change of carrier wave is carried out analysis and utilization by the signal of being sent by sensor 39 as measuring-signal.
Not only ion-selective electrode 42 uses for sensor 39, particularly measuring nitrate, oxygen content, chloride, ammonium (base), when calcium and other earth alkali metal, can replenish at any time when needing more electrode 42 for the ion of measuring other, and measure battery and also be prepared as at any time and find out vectorial redox potentiality, electric conductivity and turbidity and serve.Might give in power supply in addition and arrange 1 optical conductor in the cable of measuring instrument 1, thereby and prove corresponding molecule with this vibration of thorn laser rays stimulation molecule or rotation by its power supply.This technology is specially adapted to prove hydrocarbon, especially as benzene, and toluene, polycyclic aromatic hydrocarbon such as xylol.They occur in the saturated with water of the refuse landfill of being everlasting, so its proof has very high importance.
Because measuring instrument 1 not only is applied to underground water, in spring or the circulating water, and be applied to the infiltration water field of refuse landfill, that is to say in the very mordant medium, so whole measuring instrument must be made to such an extent that have a corrosion resistivity.The high-alloy steel that contains high chromium and nickelic composition and titanium, molybdenum potpourri has been used in the instrument manufacturing.Use composition probably to be X6CrNiMoTi17122 (material number: 1.4571).Importantly, the associated parts of all except that sensor and medium are made by so erosion-resisting sturdy material fully.Because sleeve pipe must satisfy very high mechanical requirement, thus should make firmly as much as possible, and be subjected to being positioned at the support of the sensor 39 on a plane.In addition, whole measuring instrument is subjected to explosive-proof protector.
Certainly the flexible and changeable property of surveying instrument 1 not only is confined to sensor can have different quantity and carry out different arrangements, and process of measurement can select with hope, such as the examination time with measure at interval and can regulate by the program of organized data register 5 for each sensor 39 as required.
