Description

  The present invention relates to a liquid sampling apparatus that samples and collects liquid in order to measure the radiation dose of the liquid, and more particularly to a liquid sampling apparatus suitable for sampling liquid adhered to a floor surface.

  For example, in the event that a liquid such as water leaks from the piping or tanks to the floor surface in a management area of a nuclear power plant, it is necessary to immediately perform radiation (radioactivity) measurement on the leaked liquid. That is, it is necessary to perform radiation measurement at the leakage site or to collect and analyze the leaked liquid in a plastic bottle or the like. Then, when collecting the liquid leakage on the floor surface in a plastic bottle or the like, conventionally, the liquid leakage was collected by sucking it with a dropper, or it was collected by absorbing water with a paper waste or the like.

  On the other hand, there is known a tritium inspection apparatus capable of inspecting tritium with high accuracy and in a short time with a very small amount of tritium-containing specimen (see, for example, Patent Document 1). In this apparatus, the adhesion surface of the flat plate is cooled, and the water vapor in the tritium-containing analyte supplied to the adhesion surface is condensed or solidified on the adhesion surface to form an analyte layer. A β-ray emitted from the subject layer is detected by the detection device.

As shown in FIG. 4, the check valve 43 is a valve provided with a diaphragm 431, and prevents the liquid R sucked from the suction cup 41 from flowing backward to the suction pipe 41.

  The check valve 43 and the upper portion 411a of the tube body 411 of the suction pipe 41 are connected to each other by a detachable connector 44 so as to be freely attached / detached (detachable). In other words, one end of the tubular detachable connector 44 is attached to the check valve 43, and the upper part 411 a of the suction cup 41 is inserted into and pulled out from the other end of the detachable connector 44. The check valve 43 is connected to a tube (venting means) 432 with a vent hole extending into the suction cup 41 and having a plurality of vent holes 432a formed on the side surface. In the state where the check valve 43 and the suction cup 41 are connected by the detachable connector 44, the suction cup 41 and the outflow pipe 42 are communicated with each other via the check valve 43.

  On the other hand, as shown in FIG. 6, the connection between the check valve 43 and the suction cup 41 by the detachable connector 44 is released by lifting the outflow pipe 42 side from the floor surface G (away from the suction cup 41). In the state, the communication between the suction cup 41 and the outflow pipe 42 is released. At the same time, the opening of the upper portion 411a of the suction pipe 41 and the tube 432 with a vent hole are exposed, and air (outside air) is sent into the suction cup 412 from the opening of the suction cup 41 and the vent hole 432a of the vent hole tube 432. . Thereby, the vacuum (negative pressure) in the suction cup 412 is broken, and the suction cup 412 is easily detached from the floor surface G.

  In addition, as shown in FIG. 2, the other end 42a of the outflow pipe 42, which is the other end of the suction pipe 4, is disposed in the container 2 through the cap 22 and the rubber plug 23, and the opening The outlet 42 b which is the end is arranged so as to be positioned in the vicinity of the shoulder 2 a (opening 211) of the container 2.

  The suction tool 5 is an instrument that is attached to the container holder 3 and sucks air in the container 2. That is, as shown in FIG. 1, a rod (plunger) 53 having a piston 52 at one end is slidably inserted into a cylinder 51, and a handle 54 is attached to the other end of the rod 53. A mounting plate 55 is attached to the end surface of the cylinder 51 on the piston 52 side, and the bolt 56 of the mounting plate 55 is fastened to the screw hole 38a of the connecting plate 38 so that the suction tool 5 is detachably attached to the container holder 3. It has been.

  The capacity of the cylinder 51, that is, the amount of air sucked by the suction tool 5 is set so that the amount of liquid R required for analysis such as radiation measurement can be collected by one suction. The piston 52 is provided with a plurality of O-rings 57 for maintaining airtightness.

  Such a suction tool 5 and the container 2 are connected via a suction unit 6. In the suction unit 6, a first suction tube 61 is connected to a suction pipe 65 via a suction check valve 62, a closing valve 63 and a detector (instruction means) 64.

  One end of the first suction tube 61 is inserted and arranged on the mounting plate 55 side (between the piston 52 and the mounting plate 55) of the cylinder 51 of the suction tool 5, and the other end is connected to the suction check valve 62. It is connected. This suction check valve 62 discharges only the air flowing from the first suction tube 61 side (cylinder 51 side) to the outside, and does not discharge the air flowing from the suction pipe 65 side (container 2 side) to the outside. It is a stop valve.

  Such a suction check valve 62 is fixed to the outer surface of the container holder 3, and is connected to one end of the closing valve 63 via a suction connector 66 and a second suction tube 67. The closing valve 63 is a gate valve for preventing the liquid R flowing from the suction pipe 65 from flowing into the suction tool 5 side. The suction connector 66 is a connector that connects the suction check valve 62 and the shut-off valve 63 (second suction tube 67) in a freely detachable manner.

  The other end portion of the shutoff valve 63 is connected to one end portion of the detector 64 via the third suction tube 68. This detector 64 indicates that a predetermined volume of liquid R has been stored in the container 2. That is, as shown in FIG. 2, it is composed of a transparent tube having a diameter larger than that of the suction tube 65 or the like, and is disposed so as to extend horizontally (perpendicular to the suction tube 4). Is provided. Then, as described later, when the liquid R reaches the bottom portion 2b of the container 2 and a predetermined volume is stored, the liquid R overflows into the suction pipe 65 and flows into the detector 64, and the liquid R flows into the indicator line 641. When it reaches, the indication line 641 looks thick from the outside. Thereby, it can be visually confirmed that a predetermined amount of the liquid R has been stored in the container 2, and thereafter the suction by the suction tool 5 can be stopped to prevent the liquid R from flowing into the cylinder 51 side.

  The other end of the detector 64 is connected to one end of the suction pipe 65. The suction pipe 65 is a pipe having a smaller diameter than the outflow pipe 42 of the suction pipe 4, and extends through the outflow pipe 42 and coaxially with the outflow pipe 42, as shown in FIG. The opening end 65 a that is the other end is located on the bottom 2 b of the container 2. Here, there is a gap between the opening end portion 65a and the bottom surface of the container 2 so that air in the container 2 can be sucked.

  Further, the position of the opening end portion 65a is set so that a predetermined volume of the liquid R is stored in the container 2, and in this embodiment, is set flush with the bottom 2b of the container 2. That is, when a predetermined volume of liquid R is stored in the container 2, the liquid R overflows from the opening end 65 a to the suction pipe 65 and flows into the detector 64 as described above.

  In this way, the outflow pipe 42 and the suction pipe 65 constitute a double pipe, and the suction pipe 65 sucks the air in the container 2 and the outflow pipe 42 sucks up the liquid R. That is, with the suction cup 41 and the outflow pipe 42 in communication as described above, the suction surface 412b of the suction cup 412 (one end face of the suction pipe 4) is applied to the floor G, and the piston 52 of the suction tool 5 is moved. Pull to perform suction. As a result, the air in the container 2 flows into the suction pipe 65 and is sucked into the piston 52 via the detector 64, the closing valve 63, the suction check valve 62, and the like, and the container 2 is evacuated (negatively charged). Pressure). Then, the suction pipe 4 is also evacuated, and the liquid R is sucked from the suction hole 412a, passes through the suction cup 41, the check valve 43, and the like, and is discharged from the outlet 42b of the outlet pipe 42 to the container 2. Be contained.

  The container 2 and the suction pipe 4 can be attached to and detached from the container holder 3 and the suction tool 5. That is, the suction connector 66 is detached, the suction check valve 62 and the shutoff valve 63 (second suction tube 67) are disconnected, the clasp 34 is removed, and the container 2 is taken out from the container holder 3, thereby accommodating the container. The body 2 and the suction pipe 4 can be removed.

  The container 2, the suction pipe 4, the suction pipe 65, the detector 64, the third suction tube 68, the closing valve 63, and the second suction tube 67 are previously set (integrated) as a container 2 side set. Has been. On the other hand, the container holder 3, the suction tool 5, the first suction tube 61, the suction check valve 62 and the suction connector 66 are also set in advance as a container holder 3 side set.

  Next, the usage method and operation of the liquid sampling apparatus 1 having such a configuration will be described.

  First, the fastener 34 of the container holder 3 is removed, the holder bodies 31 and 32 are opened, the container 2 is accommodated, and the holder bodies 31 and 32 are closed. Subsequently, the second suction tube 67 is connected to the suction connector 66 to close the closing valve 63, and the piston 52 of the suction tool 5 is pushed to discharge the air in the cylinder 51 from the suction check valve 62 to the outside. After that, the closing valve 63 is opened.

  Next, as shown in FIG. 1, the suction cup 412 of the suction pipe 4 is immersed in the liquid R, the suction surface 412 b is applied to the floor G, and the suction is performed by pulling the piston 52 of the suction tool 5. Thus, as described above, the liquid R is sucked from the suction hole 412 a, passes through the suction pipe 4, is discharged from the outlet 42 b of the outflow pipe 42, and is stored in the container 2. Then, when the predetermined volume of liquid R is accommodated in the container 2 and the instruction line 641 of the detector 64 looks thick, the suction by the suction tool 5 is stopped.

  When the collection of the liquid R is completed in this way, the suction cup 412 of the suction pipe 4 is separated from the floor surface G and the liquid sampling device 1 is removed. At this time, if the suction cup 412 is difficult to separate from the floor surface G, the outlet pipe 42 side is pulled up from the floor surface G as described above, and the opening of the upper portion 411a of the suction cup 41 and the tube 432 with a vent hole are connected. By exposing and sending air into the suction cup 412, the suction cup 412 is easily separated from the floor surface G.

  Next, the closing valve 63 is closed, the suction connector 66 is removed, the clasp 34 is removed, the holder bodies 31 and 32 are opened, the container 2 side set is taken out and stored in a vinyl bag or the like. And after taking out the liquid R from the container 2, since the container 2 side set may be contaminated, it is discarded, and the container holder 3 side set is reused.

The liquid R is sucked into the container 2 from the formed suction hole 412a. That is, the liquid R having a predetermined height from the floor surface G is accommodated in the container 2, and the collection of the radioactive substance originally attached to the floor surface G is suppressed / prevented. As a result, it is possible to accurately and appropriately perform radiation measurement on the liquid R leaked and adhered to the floor.

  Moreover, the liquid R on the floor G can be collected into the container 2 easily and quickly by simply sucking the suction cup 412 of the suction pipe 4 against the floor G and sucking air with the suction tool 5. Furthermore, by setting the amount of air sucked by the suction tool 5 and the volume of the container 2 to a predetermined amount, the amount of liquid R required for analysis such as radiation measurement can be collected at a time (by one suction). it can.

  Further, since the container 2 side set in contact with the liquid R is detachable with respect to the container holder 3 side set, after collecting the liquid R, the container 2 side set is removed from the container holder 3 side set and discarded. . And, at the time of the next collection, by connecting a new container 2 side set to the container holder 3 side set, contamination by residual substances to the container 2 side set once used is prevented, and an appropriate The collection is possible, and the container holder 3 side set can be reused, which is economical.

  In addition, since the detector 64 indicating that a predetermined volume of the liquid R has been stored in the container 2 is provided, a predetermined / desired amount of the liquid R can be collected appropriately and easily. Furthermore, it is possible to prevent the suction tool 5 and the like from being contaminated by excessively sucking the liquid R.
