Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of nuclear radiation detection, and in particular to a detector device and a method for replacing the same. Background Art

[0002] At present, the inspection and maintenance procedures for detectors generally require the construction of an air tent or personnel painting, and the staff must enter the environment to work. When the staff enter the environment to inspect and repair the faulty detector components, it is sometimes necessary to stop the operation, which affects the overall construction period and output. In addition, the inspection and maintenance operations are cumbersome and the construction period is long. If the detector is placed in a complex environment and the detector components are used more frequently, the inspection and maintenance process will be more cumbersome, which will increase the risk of radiation exposure to the staff when performing inspection and maintenance work in a high-dose field environment, which is harmful to their health. In addition, some radioactive substances will accumulate on the surface of the detector components that have been used for a long time, and they must be strictly decontaminated when they are transferred out of the working environment, which increases the workload and the amount of radioactive waste to be handled.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] Figure 1 FIG. 1 is a partially exploded schematic diagram of a detector device 10 according to an embodiment of the present invention. Figure 1 The detector device 10 includes a detector assembly 100 and a receiving device 200. The detector assembly 100 is used to measure measurement data of a detected object.

[0023] In some embodiments, the containment device 200 may adopt a shielding collimation structure to effectively reduce the impact of ambient radiation on the measurement data while ensuring detection of the detected object. The thickness of the containment device 200 may be changed according to the content of radiation in the environment to facilitate measurement.

[0024] In some embodiments, the detector assembly 100 is electrically connected to an external device to transmit the measured data to the external device.

[0025] In some embodiments, the external device may be a data analysis device or a data acquisition device.

[0026] See also Figure 1 The accommodating device 200 is provided with an accommodating cavity 210. The accommodating device 200 is provided with a first opening, the first opening is communicated with the cavity opening of the accommodating cavity 210, and the detector assembly 100 can be moved into the accommodating cavity 210 or moved out of the accommodating cavity 210 through the first opening.

[0027] The detector assembly 100 can be moved into or out of the accommodating cavity 210 through the first opening. The detector assembly 100 can be moved out of or into the accommodating device 200 by a clamping tool such as a manipulator to replace the detector device 10. The removed detector assembly 100 can be inspected and maintained, which shortens the inspection and maintenance time and does not affect the process. This replacement method avoids the operator working at a position close to the detector device 10, ensuring the safety of the personnel.

[0028] The receiving device 200 is rotatably connected to the cover plate 300 to open or close the first opening.

[0029] In some embodiments, when the cover 300 closes the first opening, the first end of the detector assembly 100 abuts against the bottom wall of the accommodating cavity 210, and the second end of the detector assembly 100 abuts against the cover 300, which is used to electrically connect the detector assembly 100 and the external device to ensure the stability of the detector assembly 100 in the accommodating device 200, and also to ensure the reliability of the electrical connection between the detector assembly 100 and the external device.

[0030] In the first embodiment, the detector assembly 100 includes a detector 110 and an operating head 120. The length of the operating head 120 needs to ensure that the detector 110 is in position with the detected object when in use; on the other hand, it also needs to ensure that when the cover plate 300 closes the accommodating device 200, the detector 110 is in conflict with the bottom wall of the accommodating cavity 210 to prevent the detector 110 from shaking.

[0031] Specifically, the two ends of the accommodating device 200 are a sealed end and an open end, respectively, and the detector assembly 100 is located in the accommodating cavity 210 when not being replaced. Since the detector assembly 100 is located in the accommodating device 200 when not being replaced, the surface of the detector 110 is kept clean, radioactive contamination in the environment is avoided, and subsequent removal and decontamination of the detector 110 are facilitated.

[0032] The detector 110 is used to detect the detected part. One end of the operating head 120 is connected to the detector 110. When the cover plate 300 closes the first opening, the operating head 120 is located between the detector 110 and the cover plate 300, and the other end of the operating head 120 abuts against the cover plate 300. The circumferential side of the detector 110 abuts against the inner wall surface of the accommodating device 200 to limit the displacement of the detector 110 in the radial direction, avoid shaking of the detector assembly 100 after the cover plate 300 closes the first opening, ensure the reliability of the electrical connection between the first conductor 1222 and the second conductor 320, and avoid affecting the normal transmission of the signal. In other words, the projection of the detector 110 on the first preset projection plane completely covers the projection of the operating head 120 on the first preset projection plane, and the first preset projection plane is parallel to the bottom wall of the accommodating cavity 210.

[0033] Specifically, one end of the operating head 120 is welded to the detector 110 , and the end portion refers to an end surface of the operating head 120 .

[0034] In the second embodiment, the detector assembly 100 includes a detector 110 and an operating head 120. The length of the operating head 120 needs to ensure that the detector 110 is positioned relative to the detected object when in use; and also needs to ensure that when the cover 300 closes the accommodating device 200, the detector 110 contacts the bottom wall of the accommodating cavity 210 to prevent the detector 110 from shaking.

[0035] The detector 110 is used to detect the detected object. The operating head 120 is provided with a connecting hole, and at least part of the detector 110 is detachably located in the connecting hole, and the inner wall of the connecting hole abuts against the detector 110, so as to facilitate the replacement of the detector. When the cover plate 300 closes the first opening, the operating head 120 abuts against the cover plate 300, and the outer wall surface of the operating head 120 abuts against the inner wall surface of the accommodating device 200 to limit the displacement of the operating head 120 in the radial direction, so as to avoid the shaking of the detector assembly 100 after the cover plate 300 closes the first opening, ensure the reliability of the electrical connection between the first conductor 1222 and the second conductor 320, and avoid affecting the normal transmission of the signal. In other words, the projection of the operating head 120 on the first preset projection plane completely covers the projection of the detector on the first preset projection plane, and the first preset projection plane is parallel to the bottom wall of the accommodating cavity 210.

[0036] Specifically, the inner wall of the communication hole is welded to a portion of the detector 110 .

[0037] See also Figure 1 The operating head 120 includes a wire tube 121 and a clamping member 122 .

[0038] In some embodiments, the first connecting line of the detector 110 is located in the wire tube 121. The wire tube 121 can be used to place the first connecting line of the detector 110 on the one hand, and on the other hand, the detector 110 can meet the detection requirements by adjusting the length of the wire tube 121.

[0039] When the detector 110 detects the detected object, the center of the detector 110 needs to be roughly flush with the center of the detected object. Therefore, for different detected objects, the overall length requirements of the detector assembly 100 are different, and the length of the wire tube 121 is also different. When the volume of the detected object is small, the length of the wire tube 121 is small; when the volume of the detected object is large, the length of the wire tube 121 is large. Therefore, the length of the wire tube 121 can be adjusted according to the actual use environment to ensure the detection requirements of the detector 110.

[0040] Specifically, the wire tube 121 is a tubular object. The wire tube 121 can be provided with a cavity such as a cylinder or a cuboid in which the first connecting wire can be placed.

[0041] See also Figure 1 One end of the clamping member 122 is provided with a connecting member, the connecting member is provided with a round plate, the connecting member is provided with a flat plate, and the flat plate is detachably connected to the wire tube 121 through a disassembly member. The disassembly member can be one or more of the following: screws, bolts, studs, nuts.

[0042] Specifically, the shape of the flat plate may be adapted to the shape of the wire guide.

[0043] In another embodiment, a connecting piece is detachably provided at one end of the clamping piece 122 .

[0044] When the cover plate 300 closes the first opening, the other end of the clamping member 122 abuts against the cover plate 300. That is, when the cover plate 300 closes the first opening, the clamping member 122 is located between the wire tube 121 and the cover plate 300.

[0045] In some embodiments, the operating head 120 may also include at least one connecting column and a clamp 122 , one end of the clamp 122 is detachably connected to a plate, the plate is detachably connected to the connecting column, and the connecting column is connected to the detector 110 .

[0046] See also Figure 1The clamping member 122 includes an elastic member 1221 and at least one first electrical conductor 1222. One end of the elastic member 1221 is connected to the wire tube 121, and the elastic member 1221 is provided with at least one placement hole. Each first electrical conductor 1222 is arranged in each placement hole, and one end of each first electrical conductor 1222 is connected to the first connecting line of the detector 110, so as to electrically connect the detector 110 and an external device. At least part of the first electrical conductor 1222 is located in the wire tube 121, so as to be connected to the first connecting line.

[0047] When the cover plate 300 closes the first opening, the other end of each first electrical conductor 1222 abuts against the cover plate 300 to ensure the reliability of the electrical connection.

[0048] When the cover plate 300 closes the first opening, the other end of the elastic member 1221 abuts against the cover plate 300 .

[0049] In some embodiments, the elastic member 1221 is an I-shaped member, and the placement hole passes through two oppositely arranged side surfaces of the I-shaped member. When a manipulator is used to clamp the detector assembly 100, the manipulator is used to clamp the elastic member 1221, and the movement of the detector assembly 100 is controlled by controlling the elastic member 1221. Therefore, the elastic member 1221 can be an I-shaped member to facilitate the clamping of the manipulator, ensure the stability of the mobile detector assembly 100, and prevent the detector assembly 100 from shaking or even falling when it moves into the accommodating cavity 210 through the first opening or moves out of the accommodating cavity 210 through the first opening.

[0050] Specifically, the I-shaped piece includes two first plates arranged opposite to each other and a second plate located between the two first plates. The I-shaped piece is provided with four placement holes, which are respectively located at both ends of the length direction of the two first plates. A first conductive member 1222 is placed in each placement hole.

[0051] In some embodiments, the two ends of each first conductor 1222 protrude from the two ends of the elastic member 1221, that is, the length of the first conductor 1222 is greater than the length of the elastic member 1221 in the accommodating cavity 210, so that one end is connected to the first connecting line and the other end is in close contact with the second conductor 320.

[0052] The cover plate 300 further includes a cover plate body 310 and at least one second electrical conductor 320. The cover plate body 310 rotates to open or close the first opening, and the cover plate body 310 is provided with a pit on the side facing the accommodating device 200. At least one second electrical conductor 320 is provided at the pit, for example, the second electrical conductor 320 may be located at the bottom of the pit, and a second connecting line is connected to the side of the second electrical conductor 320 in contact with the cover plate body 310, and the second connecting line passes through the cover plate body 310 to connect with an external device. The first connecting line and the second connecting line are connected by contact connection between the first electrical conductor 1222 and the second electrical conductor 320, thereby realizing electrical connection between the detector 110 and the external device. That is, the detector 110, the first connecting line, the first electrical conductor 1222, the second electrical conductor 320, the second connecting line and the external device are connected in sequence.

[0053] When the cover 300 closes the first opening, each first conductive member 1222 is in contact with each second conductive member 320. The material of the elastic member 1221 needs to meet at least two points: elastic and non-conductive. When the cover 300 closes the first opening, the elastic elastic member 1221 can use the elastic force generated by its own deformation to apply force to the detector 110 and the second conductive member 320. On the one hand, it can ensure the close contact between the first end of the detector 110 and the bottom wall of the accommodating cavity 210, avoid the shaking of the detector 110, and improve the detection accuracy of the detector 110; on the other hand, it makes the first conductive member 1222 and the second conductive member 320 in close contact, avoids the circuit virtual connection when the first conductive member 1222 and the second conductive member 320 are in contact, and ensures the reliability of the electrical connection between the detector 110 and the external device. In addition, when the cover 300 is used to close the first opening, it can buffer the force applied by the second conductive member 320 to the first conductive member 1222 to avoid excessive pressure from damaging the detector 110. Therefore, the elastic member 1221 may be made of one or more of the following materials: polyethylene material, or rubber.

[0054] In some embodiments, the detector assembly 100 includes a detector 110, a wire tube 121 and a clamping member 122, the clamping member 122 includes an elastic member 1221 and a first electrical conductor 1222, the detector 110, the wire tube 121 and the elastic member 1221 are connected in sequence, when the detector assembly 100 is located in the accommodating cavity 210, the first end of the detector 110 abuts against the bottom wall of the accommodating cavity 210, the second end of the detector 110 is connected to the wire tube 121, and the first end and the second end of the detector 110 are arranged relative to each other.

[0055] Specifically, the detector assembly 100 includes a detector 110 and a copper column, and the copper column is electrically connected to the detector 110. The cover plate 300 includes a copper sheet, and the copper sheet is electrically connected to an external device. When the cover plate 300 closes the first opening, the copper column and the copper sheet are in contact and connected to achieve electrical connection between the detector 110 and the external device. The detector 110, the first connecting wire, the copper column, the copper sheet, the second connecting wire and the external device are connected in sequence.

[0056] See also Figure 1 The detector device 10 further includes a first connecting portion 400 and a second connecting portion 500 .

[0057] In some embodiments, the first connection portion 400 is disposed on one of the inner wall surface of the detector assembly 100 and the accommodating cavity 210, and the first connection portion 400 is provided with a protrusion 410. The second connection portion 500 is disposed on the other of the inner wall surface of the detector assembly 100 and the accommodating cavity 210, and the second connection portion 500 is movably connected to the first connection portion 400, and the second connection portion 500 is provided with a groove 510.

[0058] When the detector assembly 100 moves into the accommodating cavity 210 through the first opening or moves out of the accommodating cavity 210 through the first opening, the protrusion 410 can move in the groove 510. When the detector assembly 100 moves into the accommodating cavity 210 through the first opening, since the first electrical conductor 1222 and the second electrical conductor 320 need to be in contact and connected, the position of the detector assembly 100 in the accommodating device 200 can be limited by the cooperation of the protrusion 410 and the groove 510 to ensure the accuracy of the contact between the first electrical conductor 1222 and the second electrical conductor 320.

[0059] Specifically, the detector device 10 further includes a first connection portion 400 and a second connection portion 500. The first connection portion 400 is disposed on one of the inner wall surface of the wire tube 121 and the accommodating chamber 210, and the first connection portion 400 is provided with a protrusion 410. The second connection portion 500 is disposed on the other of the inner wall surface of the wire tube 121 and the accommodating chamber 210, and the second connection portion 500 is movably connected to the first connection portion 400, and the second connection portion 500 is provided with a groove 510. When the detector assembly 100 moves into the accommodating chamber 210 through the first opening or moves out of the accommodating chamber 210 through the first opening, the protrusion 410 can move in the groove 510.

[0060] The lengths of the protrusion 410 and the groove 510 are related to the length of the wire tube 121 . When the length of the wire tube 121 is longer, the lengths of the protrusion 410 and the groove 510 are longer, which can improve the stability of the detector assembly 100 in the accommodating cavity 210 .

[0061] See also Figure 1The first connection part 400 is disposed on the wire tube 121, and the first connection part 400 is provided with a positioning pin. The second connection part is disposed on the inner wall surface of the accommodating cavity 210, and the second connection part 500 is provided with a groove 510. When the detector assembly 100 moves into the accommodating cavity 210 through the first opening or moves out of the accommodating cavity 210 through the first opening, the positioning pin can move in the groove 510.

[0062] Figure 2 is a schematic structural diagram of a detector device 10 according to an embodiment of the present invention. Figure 2 The detector 110 further includes a third connection portion 600. The third connection portion 600 includes at least one hinge 610, and the cover plate 300 is rotatably connected to the receiving device 200 via the hinge 610.

[0063] In other embodiments, the third connection portion 600 may include at least one torsion spring, and the cover plate 300 is rotatably connected to the accommodating device 200 via the torsion spring. When the detector assembly 100 needs to be replaced, due to the force of the torsion spring, the cover plate 300 is in a state of always opening the first opening during the operation, which facilitates the operation of the detector assembly 100. Once the spring buckle 710 is separated from the engaging portion and escapes from the engaging portion, the cover plate can be automatically opened due to the force of the torsion spring.

[0064] See also Figure 2 The cover plate 300 is rotatably connected to the accommodating device 200 via two hinges 610 , and the axis of rotation is one side of the cover plate body 310 .

[0065] See also Figure 2 The detector device 10 further includes a fourth connection portion 700 and a fifth connection portion. The fourth connection portion 700 is disposed on one of the accommodating device 200 and the cover plate 300, and the fourth connection portion 700 is provided with a spring buckle 710. The fifth connection portion is disposed on the other of the accommodating device 200 and the cover plate 300, and the fifth connection portion is detachably connected to the fourth connection portion 700, and the fifth connection portion is provided with a snap-fit ​​portion.

[0066] The spring buckle 710 can be engaged with the engaging portion to close the first opening of the cover plate 300 ; the spring buckle 710 can be separated from the engaging portion and escape from the engaging portion to open the first opening of the cover plate 300 .

[0067] Specifically, the fourth connection part 700 is disposed on the outer wall surface of the accommodating device 200, and the fourth connection part 700 is provided with a spring buckle 710. The fifth connection part is disposed on the cover plate 300, and the fifth connection part is provided with a groove 510. The spring buckle 710 can be engaged with the groove 510, so that the cover plate 300 closes the first opening; the spring buckle 710 can also be disengaged from the groove 510, so that the cover plate 300 opens the first opening.

[0107] The detector device of this embodiment can be installed outside a reactor, or in a special radioactive activity environment (such as the operation of highly radioactive materials in a hot room or a glove box), or in a highly radioactive material warehouse, or in a highly radioactive material operation environment.

[0108] The following takes the inspection and maintenance of the detector device 10 located in a high neutron / gamma dose field or a high toxicity environment such as a hot room or a glove box as an example to specifically explain the detector device 10 and the method of replacing the detector 110.

[0109] When the detector 110 needs to be replaced, the spring buckle 710 is pressed by a manipulator, and the spring buckle 710 is disengaged from the engaging portion. The cover body 310 rotates to open the first opening. The manipulator clamps the clamp 122 to remove the used detector assembly 100 in the accommodating chamber 210. The manipulator clamps the clamp 122 and places the unused detection assembly in the accommodating chamber 210 through the positioning of the protrusion 410 and the groove 510. When the first end of the detector 110 contacts the bottom wall of the accommodating chamber 210, the cover 300 rotates to close the first opening. The spring buckle 710 is matched with the engaging portion to fix the cover 300. To protect the operator from dose irradiation, simplify the inspection and maintenance process of the detector 110 and shorten the inspection and maintenance time, and at the same time reduce the contamination of the radioactive waste collected by the detector 110, which is conducive to the cleaning of radioactive waste and will not affect the process. It is simple to operate and easy to use.
