| titleOfInvention | Electrical conductivity measuring device for undisturbed samples in laboratory |
| abstract | The present invention relates to a device for measuring electrical conductivity indoors, and more particularly, by transporting a control sample collected in a ground investigation to a test laboratory and measuring electrical conductivity indoors, maintaining conditions as similar as possible to the ground conditions of the site and measuring equipment Comparison in the room to promote light weight, miniaturization, convenience and economy together relates to a sample electrical conductivity measuring device, A specific solution of the present invention is, "The front and back of the rectangular bottom plate 100 and the upper side are open, and closing plates 110 are formed at both ends, and gripping holes 111 are formed on the top of the closing plate 110, and the gripping holes 111 An adjustment hole 112 is perforated in the center of the lower part, and at one end of the seating housing 10 formed with a concave mounting plate 120 at a predetermined distance from the bottom plate 100 to the inside of the closing plate 110. The plate 200 is provided and the electrode bar 210 formed long through the center of the plate 200 to the other end is formed integrally with the first measuring means 20 and the central rear end of the bottom plate 100. A connection that is slidably connected in a state in which a support 30 coupled vertically and having a long sliding ball 300 perforated and a first fitting part 400 fitted into the sliding ball 300 are provided on one side Long holes 500 are formed on both sides at a predetermined interval from the bar 40, and a fixing hole 501 is drilled in two stages in the center, so that the connecting bar 40 is fixedly coupled to the horizontal bar 50 and the long hole It includes a second measuring means 60 coupled to the sample tube 70 to measure the electrical conductivity of the sample provided in the sample tube 70, 40 to 87% by weight of water and poly(acrylic acid-co-maleic acid) sodium salt [POLY (ACRYLIC ACID -CO-MALEIC ACID)SODIUM SALT] or poly(4-styrenesulfonic acid-co-maleic acid) sodium salt [POLY(4-STYRENESULFONIC ACID-CO-MALEIC ACID) 5 to 10% by weight and polyurethane resin ( POLYURETHANE RESIN) 5 to 30% by weight and polyvinyl alcohol (POLYVINYL ALCOHOL) 3 to 20% by weight of a mixture of coating agent applied indoors, including a comparison sample electrical conductivity measuring device, A bolt 311 is provided on one side so as to be fastened to the first fitting part 400 inserted into the sliding ball 300, and the other side presses the wall surface of the sliding ball 300 to position the connecting bar 40. An indoor comparison sample electrical conductivity measurement device including a first fastening part 310 integrally formed with a handle 312 for fixing, The second measuring unit 60, A long slit 601 is formed in the center of one side in the vertical direction in a rectangular shape, and at the end of the slit 601, a circular coupling hole 602 is formed long in the vertical direction, and is inserted into the long hole 500 at the rear side. A plurality of brackets 600 having a second fitting portion 603 and having a screw hole 604 perforated at one side of the front center; an electrode needle 610 coupled through the coupling hole 602; A bolt 621 is provided on one side so as to be fastened to the second fitting part 603 inserted into the long hole 500, and the other side presses the wall surface of the long hole 500 to fix the position of the bracket 600. a second fastening part 620 in which a handle 622 is integrally formed; A bolt 631 is provided on one side to be coupled to the screw hole 604, and a handle 632 is integrated on the other side so that the distance between the slits 601 can be adjusted by pressing the outer surface of the screw hole 604. A slit spacing adjusting unit 630 formed of; Comparison in the room containing a sample electrical conductivity measuring device, The sample tube 70 has a cylindrical shape and has a plurality of holes 700 perforated at regular intervals on its outer circumferential surface, and a comparison sample electrical conductivity measurement device in the room, A comparison sample electrical conductivity measuring device in the room, including a mounting bracket 121 having a relatively small diameter to be additionally coupled to the inside of the mounting plate 120, To prevent discoloration or corrosion on the outer circumferential surfaces of the seating housing 10, support 30, connecting bar 40, and horizontal bar 50, UV coating is performed, and the UV coating agent is trimethylolpropane EO modified triacrylate 44 to 54% by weight, 17 to 27% by weight of 2-propenoic acid 1,6-hexanediyl, 4 to 14% by weight of 2-hydroxy-2-methyl-1-phenyl-1-propanone, benzophenone 1 ~ 10% by weight, aromatic light naphtha solvent containing 0.1 ~ 4% by weight of indoor comparative sample electrical conductivity measuring device "with its structural characteristics, The present invention configured as described above, By transporting the non-fermented samples collected from the ground investigation to the laboratory and measuring the electrical conductivity indoors, it is possible to maintain conditions as similar as possible to the ground conditions at the site and to promote light weight, miniaturization, convenience and economy of the measuring equipment. By providing a mounting bracket for gripping the sample tube to be applicable to sample tubes having various lengths and diameters, the effect of promoting compatibility of the sample tube is exhibited. |
