In the radioactivity prospecting body 3 of the present invention, its cylinder 7 with can adopt following two kinds of structures being connected of radioactivity seeker 8:
1, as Fig. 3, can vertically inwardly have groove 12 on cylinder 7 sidewalls, the diameter and the length of the internal diameter of this groove 12 and length and radioactivity seeker 8 match, opening 13 sizes of this groove 12, according to the model of radioactivity seeker, can in 7-9 millimeter scope, select.Make radioactivity seeker can detect the definite position of fracture seepage exactly.
2, as Fig. 4, also can vertically have the mounting hole 14 that a plurality of diameters and the degree of depth and radioactivity seeker 8 diameters and length match at cylinder 7 edges, be generally 3-10, they evenly distribute, be used to place a plurality of radioactivity seekers 8, its principle of work as hereinbefore.
Among the present invention, but magnetic detector 5 horizontal settings in cylinder 7 upper ends of radioactivity prospecting body 3, pressure detector 6 can be placed in the lower end of cylinder 7.
Can be connected with throwing source device 15 in radioactivity prospecting body 3 lower ends, this is thrown source device 15 and is made up of motor 16, isotope can 17 and piston 18, link to each other with the radioactivity prospecting body drive motor 4 of cylinder 7 lower ends above the motor 16, they one are located in the monoblock type cover body 1, cover body 1 lower end links to each other with isotope can 17, it is suitable for reading that motor 16 is positioned at container 17, its motor shaft 21 stretches into and is positioned at its center in the container 17, screw thread is connected with piston 18 on the motor shaft 21, be provided with isotope solution 19 in the container 17, its underpart sidewall has a plurality of micropores 20.
When the present invention works, tester of the present invention is put into the wellhole water of accomplishing fluently, the present position should be positioned at the position of measured layer in its well, the lead 10 that its signal processing circuit 2 is drawn is connected to well outer notebook computer 11 or other surveying instrument, after arrangement finishes, can make motor 16 work of throwing source device 15 by ground notebook computer 11 control signal treatment circuits 2, motor shaft 21 rotates, its helicitic texture moves down piston 18, radioisotope solutions 19 in the container 17 are extruded from the micropore 20 of container 17 bottoms, made the water isotope on the mark equably in the well.After finished in the throwing source, signal processing circuit 2 was just controlled each detector energising work, and pressure transducer 6 is delivered to computer 11 after the signal that records is handled by signal processing circuit 2, demonstrates the residing depth of apparatus of the present invention.Radioactivity seeker 8 (as Geiger counter tube) begins counting simultaneously.When being hole stream for ground water aquifer, because being symmetry, hole stream distributes, when then isotope solution 19 uniform labellings of launching when throwing source device 15 are in WIH, if WIH is static, then the counting of each counter tube 8 measurement is identical, and from ground computer 11, show, if WIH flows, then the labelled with radioisotope of current water is uneven distribution, promptly the isotope counting of measuring near the counter tube 8 of direction in the water-bearing zone inflow well is just little, and the isotope counting of measuring near the counter tube 8 that flows out the water-bearing zone direction in the well is just big, just the direction of current can be shown after the counting that will measure of each counter tube 8 is handled by computer 11 like this.But the flow direction that these current show is the water (flow) direction with respect to zero-bit counter tube 8, the staff is owing to can't know the relative orientation of zero-bit counter tube 8 and big terrestrial magnetic pole on ground, so still can not learn the actual direction of current, so the present invention has inserted high precision magnetic detector 5 (as magnetic detector a little less than the high precision), the datum line of this magnetic detector 5 is owing to point to zero-bit counter tube 8 all the time, so magnetic detector 5 just indicates the angle between the zero-bit counter tube 8 and the earth arctic all the time, angle between this angle and zero-bit counter tube 8 and the current superposes after the computing, just can in computer 11, demonstrate between the hole current and the earth arctic actual flow to.When being crack stream for ground water aquifer, because being asymmetry, crack stream distributes, then the peaked site error of radioactive isotope surveyed of radiation monitor 8 is bigger, start the drive motor 4 of radioactivity prospecting body 3 this moment, and under the control of ground computer 11, drive cylinder 7 and do rotation (solve and move problem of transmission) in positive and negative 180 degree, make the radioactivity seeker 8 that is set to zero-bit accurately find the particular location of fracture seepage, because, the particular location that seepage flow takes place in the crack is exactly the position that the maximal value counter tube is set to the radioactivity seeker 8 of zero-bit, and this position is exactly magnetic detector 5 true bearing with the earth arctic that detect.So just need not to calculate the angle between magnetic detector 5 and the zero-bit radioactivity seeker 8, the water (flow) direction that zero-bit radioactivity seeker 8 is surveyed is exactly the direction that magnetic detector 5 detects, deliver to computer 11 by signal processing circuit 2 again and handle, just can in computer 11, demonstrate between the crack current and the earth arctic actual flow to.In like manner can find secondary crack and three grades of cracks, cooperate magnetic detector 5 location again, can determine the accurate flow direction of crevice water seepage flow like this, precision is higher.
During velocity measurement, determine the number of times and the time of measurement according to the size of flow velocity, the counting that this moment, each counter tube 8 recorded is superimposed as the counting of a counter tube 8, because the dilution rate of isotope solution 19 has corresponding relation in the speed of Groundwater Flow and the well, so just can go out water velocity through computer 11 processes and displays as long as record the counting size and the corresponding relation of time of each counter tube 8.
In the technical solution of the present invention, if the degree of depth that tester of the present invention drops in the well is definite with other method or instrument, as the cable length labelling method, or length numeration instrument etc., the pressure transducer 6 in the tester then of the present invention can omit.
