Description

[Technical field]

[0001] The present invention relates to a variable detector and an image capturing device including the same. More specifically, the present invention relates to a variable detector that is deformable relative to the outer circumferential surface of an inspection object and can capture a radiation image, and an image capturing device including the same. [Background technology]

[0002] Non-destructive testing methods refer to methods for inspecting the material, performance, condition, presence or absence of defects, etc. of an object without destroying it. Using non-destructive testing methods, it is possible to check the internal structure and defects of an object without destroying it, and for example, it is possible to inspect the quality of various industrial products at industrial sites, check the presence or absence of defects in buildings, and check the wear / corrosion state.

[0003] In the case of performing non-destructive testing using X-ray among the non-destructive testing methods, a hollow cylindrical object, for example, a pipe, can be the object of testing. Meanwhile, there is a demand for a structure or method that can easily measure the dimensions (e.g., radius, etc.) of the object of testing photographed during the non-destructive testing without a separate measuring device.

[0004] However, the variable detector is bent to encase the outer peripheral surface of the object to be inspected. However, bending the variable detector can cause problems such as stress being generated between the components of the variable detector, which have a layered structure, or tensile force being applied to the radiation detection panel, causing damage.

[0005] In addition, the X-ray detection panel and electrical elements provided inside the variable detector must be protected from the inflow of external foreign matter such as moisture and dust. [Prior art documents] [Patent documents]

First, when referring to components in each drawing, it should be noted that the same components are given the same reference numerals as much as possible even when they are shown in different drawings. In addition, in the description of the present invention, if a detailed description of related known configurations or functions is determined to make the gist of the present invention unclear, the detailed description thereof will be omitted. In addition, although preferred embodiments of the present invention will be described below, the technical idea of ​​the present invention is not limited or restricted thereto, and can be modified and variously implemented by those skilled in the art. In addition, various embodiments of the present invention described below can be combined with each other.

[0045] Fig. 1 is a perspective view of a variable detector according to an embodiment of the present invention, and Fig. 2 and Fig. 3 are exploded perspective views of the variable detector according to an embodiment of the present invention. Also, Fig. 4 is a diagram for explaining a first slide structure in the variable detector according to an embodiment of the present invention.

[0046] In the following embodiments, the X-axis direction represents a first direction (length direction), the Y-axis direction represents a second direction (width direction) perpendicular to the first direction, and the Z-axis direction represents a vertical direction (thickness direction) perpendicular to both the first and second directions. The XY plane formed by the X-axis and Y-axis represents a horizontal plane, and the XZ plane formed by the X-axis and Z-axis represents a vertical plane.

[0047] Referring to FIG. 1, a variable detector 1 according to one embodiment of the present invention includes a flexible panel portion 10, a main frame portion 60 coupled to one side of the panel portion 10, and an end frame portion 70 coupled to the other end of the panel portion 10.

[0048] The panel unit 10 may be configured by stacking a plurality of panels and bent so as to surround the outer peripheral surface of the inspection target. A radiation detection unit 20 capable of detecting radiation is provided inside the panel unit 10.

[0049] The main frame unit 60 includes a housing 62 made of a non-elastic material or a material having greater rigidity than the panel unit 10, and electronic elements and circuits for controlling the radiation detection unit 20 may be provided inside the housing 62. The main frame unit 60 may further include a connection port 64 for electrically connecting or communicating with other devices.

[0050] The end frame portion 70 is coupled to the panel portion 10 on the opposite side to the main frame portion 60. The end frame portion 70 may be made of a non-elastic material or a material having a higher rigidity than the panel portion 10.

[0051] 2 and 3, there are shown detailed configurations and connection configurations of the panel section 10, the main frame section 60, and the end frame section 70. In Fig. 2 and Fig. 3, the connection between the components can be performed using screws or adhesive. Since such a method of connecting the components is a common means, it should be noted that a detailed description of the means such as the use of screws or adhesive for connecting the components will be omitted unless there are special cases in the present invention.

[0052] The panel unit 10 may include a radiation detection unit 20, and a first protective panel 12 and a second protective panel 16 provided on a first surface and a second surface, respectively, of the radiation detection unit 20. In one embodiment, one side of the first protective panel 12 may be fixed to a main frame unit 60, and one side of the second protective panel 16 may be fixed to the main frame unit 60 with the radiation detection unit 20 sandwiched therebetween.

[0053] The radiation detection unit 20 may include a detection panel unit 30 including a detection panel 32 therein. In one embodiment, the radiation detection unit 20 may include a protective exterior 22 that encases the detection panel unit 30. The protective exterior 22 may be made of a flexible material and may function as a housing for accommodating the detection panel unit 30. The protective exterior 22 may be made of rubber, urethane, silicon, a carbon composite material, plastic, or the like that is radiation-transmissible and has a variable shape. In one embodiment, the protective exterior may be made of silicon rubber. Since the internal detection panel 32 is encased by the protective exterior 22, waterproof and dustproof performance may be improved.

[0054] 2, a coupling portion 24 coupled to the main frame portion 60 may be formed on a first surface side of one side of the radiation detection unit 20. In one embodiment, the coupling portion 24 includes a first opening 26 through which a terminal 28 of the detection panel 32 may be exposed.

[0055] In one embodiment, the protective exterior 22 may be configured to directly or indirectly seal the remaining portion except for the first opening 26. The detection panel 32 may be housed inside the protective exterior 22 and protected from moisture, dust, and the like.

[0056] The first and second protective panels 12 and 16 are located on the upper surface (first surface) and lower surface (second surface) of the radiation detection unit 20, and may be made of rubber, urethane, silicon, a carbon composite material, plastic, or the like that is radiation-transmittable and shape-variable. In one embodiment, the first and second protective panels 12 and 16 may be made of carbon fiber reinforced plastic (CFRP). Although the second protective panel 16 has been illustrated as being coupled to the lower surface of the radiation detection unit, the second protective panel 16 may be attached to the lower surface of the protective exterior 22 of the radiation detection unit 20 using an adhesive or double-sided tape. In some cases, when the protective exterior 22 is injection molded, the second protective panel 16 may be included in one side of the protective exterior 22 by an insert injection method, and the protective exterior 22 and the second protective panel 16 may be manufactured as one combined body.

[0057] The mainframe portion 60 may include a housing 62 and a control module 68 embedded in the housing 62. The control module 68 may include electronic elements and circuitry for controlling the detection panel 32 and / or processing detection signals of the detection panel 32. In one embodiment, such a control module 68 may be configured as a printed board assembly (PBA).

[0058] 3, the main frame unit 60 includes a second opening 66 on its bottom surface and can communicate with the first opening 26 of the radiation detection unit 20 through the second opening 66. In one embodiment, the terminal 28 of the detection panel 32 provided in the radiation detection unit 20 may be connected to the control module 68 through the first opening 26 and the second opening 66. However, in carrying out the present invention, it is not necessarily required that the radiation detection unit 20 and the main frame unit 60 are provided with the first opening and the second opening, and the detection panel unit may be connected to the control module 68 of the main frame unit 60 through a separate connector.

[0059] The end frame portion 70 is coupled to an end of the radiation detection unit 20. The end frame portion 70 may be adhered to the end of the radiation detection unit 20 with an adhesive or fixed using a fixing screw. A first slide structure, which will be described later, is formed in the end frame portion 70.

[0060] One side of the first protective panel 12 is fixed to the housing of the main frame unit 60, and the other side of the first protective panel 12 is coupled to the end frame unit 70. The other side of the first protective panel 12 is coupled to the end frame unit 70 by forming a first sliding structure, so that when the panel unit 10 is deformed, the end of the first protective panel 12 can slide within a predetermined range via the first sliding structure.

[0061] 2 to 4, the first slide structure may be composed of an end frame portion 70 and a stopper 80. As shown in FIG.

[0062] The end frame unit 70 includes an end frame body 72 and an end frame cover 76. The end frame body 72 may be coupled to an end of the radiation detection unit 20, and the end frame cover 76 may be coupled to a first surface of the end frame body 72. The end frame body 72 and the end frame cover 76 are coupled to form a space therebetween, and the stopper 80 is slidably coupled between the end frame body 72 and the end frame cover 76.

[0063] A groove-shaped first slide guide 74 extending in the X-axis direction is formed on the upper surface of the end frame main body 72, and a groove-shaped second slide guide 78 extending in the X-axis direction is formed on the bottom surface of the end frame cover 76.

[0064] The stopper 80 includes a stopper body 82, and slide protrusions 83a and 83b formed in the Z-axis direction from the stopper body 82. The first slide protrusion 83a may be inserted into the first slide guide 74, and the second slide protrusion 83b may be inserted into the second slide guide 78.

[0065] Either the first slide protrusion 83a or the second slide protrusion 83b can be inserted into the stopper connecting hole 14 of the first protective panel 12, thereby allowing the end of the first protective panel 12 to be slidably connected to the end frame portion 70.

[0066] In implementing the present invention, it is also possible that only one of the slide guides, the first slide guide 74 or the second slide guide 78, is provided, and only one of the slide protrusions, the first slide protrusion 83a or the second slide protrusion 83b, is provided corresponding to the slide guide.

[0067] The stopper 80 is slidable in the X-axis direction with the slide protrusions 83a, 83b guided by the slide guides 74, 78. The stopper 80 slides in the space between the end frame body 72 and the end frame cover 76, and a limit position or distance at which the stopper 80 can slide is set, thereby limiting the maximum allowable bending degree of the variable detector 1.

[0068] 2 to 4 show an example in which the stopper 80 is configured separately from the first protective panel 12, but in carrying out the present invention, the stopper 80 can also be formed integrally with the first protective panel 12. Needless to say, the stopper 80 can be modified into various structures as long as it is a structure for limiting the maximum degree of bending of the first protective panel 12.

[0069] The second protective panel 16 is coupled to a second surface side of the radiation detection unit 20. One side of the second protective panel 16 is coupled to the lower side of the housing 62 of the main frame unit 60 via the radiation detection unit 20. The other side of the second protective panel 16 is coupled to the end frame unit 70.

[0070] One side end of the first protective panel 12 is fixed to the housing 62 of the main frame portion 60, and the other side end of the first protective panel 12 is slidably coupled to the end frame portion 70 by the first slide structure. In contrast, both side ends of the second protective panel 16 are fixed to the lower side of the housing 62 of the main frame portion 60 and the end frame portion 70. With this configuration, when the panel portion 10 is bent, both side ends of the second protective panel 16 do not slide, and one side end of the first protective panel 12 can slide by the first slide structure. However, in the practice of the present invention, it goes without saying that the first slide structure can also be provided for the second protective panel 16, or both side ends of the first protective panel 12 can be fixed and the first slide structure can be formed on the second protective panel 16.

[0071] On the other hand, since the second protective panel 16 is made of a flexible material, when one side end of the second protective panel 16 is fixed to the housing side of the main frame portion 60, an auxiliary panel 18 made of a non-elastic material or a material with greater rigidity than the second protective panel 16 may be further provided on the outside of the second protective panel 16.

[0072] Although the radiation detection section 20, main frame section 60, first protective panel 12, second protective panel 16 and end frame section 70 are shown to be joined using screws in the figures, these connections can also be made using adhesive.

Also, the coupling part 24 of the first opening 26 may be provided with a screw hole 24c, so that the coupling part 24 may be coupled to the bottom surface of the housing 62. Also, a fixing rod insertion hole 24d may be provided in a part of the coupling part 24. One side end of the detection panel unit 30 may be fixed through the fixing rod insertion hole 24d. In one embodiment, a fixing rod is protrudingly formed on the first connecting piece 38a described below, and one side of the detection panel unit 30 can be fixed near the first opening 26 of the protective exterior 22 by inserting the fixing rod into the fixing rod insertion hole 24d.

[0075] 6 and 7, a detection panel unit 30 is provided inside the protective exterior 22 of the radiation detection unit 20.

For example, the detection panel 32 may include a variable TFT (flexible thin film transistor) 33, and may convert light emitted by a fluorescent material in response to radiation transmitted through an object to an electric (charge) signal to obtain image information.

[0077] The detection panel 32 may include a read out IC (ROIC) sensor and a gate sensor in a chip on film (COF) form, and the ROIC sensor and the gate sensor may be made of a variable material or have a variable structure.

[0078] The first and second inner protective panels 34, 36 may be made of a flexible material that is radiotransparent. The first and second inner protective panels 34, 36 may function to protect the detection panel 32.

[0079] The connecting piece 38 includes a first connecting piece 38a and a second connecting piece 38b, and one side of the detection panel unit 30 can be assembled by connecting the first connecting piece 38a and the second connecting piece 38b with a screw or the like.

In one embodiment, one side of the detection panel 32 may be fixed to the third connecting piece 38c via the first fixing portion 33a, and the other side of the detection panel 32 may be fixed to the slide panel 48 via the second fixing portion 33b. The first and second fixing portions 33a, 33b may be formed using an adhesive or an adhesive film.

[0082] The first and second inner protection panels 34, 36 are formed with first and second slide long holes 35, 37, respectively, and the slide panel 48 is formed with a third slide long hole 49. The guide protrusion 45 formed on the inner end frame body 42 is inserted into the second slide long hole 37 formed on the second inner protection panel 36, the third slide long hole 49 formed on the slide panel 48, and the first slide long hole 35 formed on the first inner protection panel 34. This configuration constitutes a second slide structure (in the present invention, the second slide structure may also be referred to as an "inner slide structure"). When the detection panel unit 30 is bent, the ends of the first and second inner protection panels 34, 36 slide with the guide protrusions 45 inserted into the first and second slide long holes 35, 37. Furthermore, since the detection panel 32 has its end fixed to the slide panel 48, when the detection panel section 30 is bent, the slide panel 48 slides with the guide protrusion 45 inserted into the third slide long hole 49 of the slide panel 48, thereby enabling the detection panel 32 to slide in the X-axis direction.

[0083] The operation of the slide structure provided in the variable detector 1 according to the present invention when the variable detector 1 is bent relative to an object to be inspected will be described below.

[0084] FIG. 8 is a side view of a variable detector according to one embodiment of the present invention, and FIG. 9 is a cross-sectional view (cross-section along the A-A' direction in FIG. 8) showing the operating state of a sliding structure according to the bending state of a variable detector according to one embodiment of the present invention.

[0085] A force is applied to the variable detector 1 in the direction F in Fig. 8 to bend the variable detector 1. Fig. 9(a) shows the variable detector 1 in an unbent state, and Fig. 9(b) shows the variable detector 1 in a bent state.

[0086] As shown in FIG. 9(a), when the variable detector 1 is not bent, the stopper 80 coupled to the end of the first protective panel 12 is located in a neutral position with the slide protrusions 83a and 83b inserted into the slide guides 74 and 78 formed on the end frame body 72 and the end frame cover 76. Also, the slide panel 48 to which the end of the detection panel 32 is fixed and each end of the first and second inner protective panels 34 and 36 are located in a neutral position in the space between the inner end frame body 42 of the inner end frame part 40 and the inner end frame cover 50. The guide protrusions 45 formed on the end frame body 42 are inserted into the slide long holes 49, 35, and 37 formed on the slide panel 48 and the first and second inner protective panels 34 and 36, respectively. Here, the neutral position can be understood as the position of the stopper 80, the slide panel 48, and each end of the first and second inner protective panels 34 and 36 when the variable detector 1 is not bent.

[0087] As shown in FIG. 9B, when the variable detector 1 is bent, the stopper 80 coupled to the end of the first protective panel 12 is moved to the first position with the slide protrusions 83a and 83b inserted into the slide guides 74 and 78 formed on the end frame body 72 and the end frame cover 76. The movement position of the stopper 80 is determined by the degree of bending of the variable detector 1, and the maximum movement distance is limited by the slide guides 74 and 78 (i.e., there is a limit point of the first position). By limiting the maximum movement distance of the stopper 80, excessive deformation of the variable detector 1 is prevented. In addition, the slide panel 48 to which the end of the detection panel 32 is fixed and each end of the first and second inner protective panels 34 and 36 move to their respective first positions in the space between the inner end frame body 42 and the inner end frame cover 50 of the inner end frame part 40. Here, the first position can be understood to be the position of each end of the stopper 80, the sliding panel 48, and the first and second inner protective panels 34, 36 when the variable detector 1 is bent.

[0088] Such a sliding structure can minimize the tensile force applied to the detection panel 32 when the variable detector 1 is bent.

[0089] FIG. 10 is a cross-sectional view (cross-section along the line AA' in FIG. 8) showing another embodiment of a sliding structure according to a bending state of a variable detector according to an embodiment of the present invention.

[0090] 10 differs in that the lengths of slide guides 74, 78 formed on an end frame body 72 and an end frame cover 76 extend further to the left compared to FIG. 9, but the other configurations are the same.

[0091] FIG. 10(a) shows the variable detector 1 in an unbent state, FIG. 10(b) shows the variable detector 1 in an unbent state when a force is applied as in FIG. 8, and FIG. 10(c) shows the variable detector 1 in an unbent state when a force is applied in the opposite direction to that shown in FIG. 8, resulting in the variable detector 1 being bent in the opposite direction to that shown in FIG. 10(b).

[0092] In Fig. 10, the position of the stopper 80 may be a neutral position in Fig. 10(a), a first position in Fig. 10(b), and a second position in Fig. 10(c). The variable detector 1 in Fig. 10 is for the case where the variable detector 1 is bent not only in one direction but in both directions as in Fig. 9. The first position in Fig. 10(b) is for limiting the maximum bending of the variable detector 1 when it is bent toward the second protective panel 16, and the second position in Fig. 10(c) is for limiting the maximum bending of the variable detector 1 when it is bent toward the first protective panel 12. Since the maximum movement distance of the stopper 80 is limited, excessive deformation of the variable detector 1 in both directions is limited.

[0093] On the other hand, in Figures 10(b) and (c), it can be seen that the sliding panel 48 to which the end of the detection panel 32 is fixed and the ends of the first and second inner protective panels 34, 36 slide and move in response to the bending of the variable detector 1.

[0094] FIG. 11 is a schematic diagram of an image capturing device including a variable detector according to one embodiment of the present invention, and FIG. 12 is an exemplary diagram showing the system configuration of an image capturing device including a variable detector according to one embodiment of the present invention.

[0095] 11, the variable detector 1 can be attached along the outer circumferential surface of the inspection object P. A fixing part 2 made of a band, string, wire, belt, ratchet belt, chain, Velcro, or the like may be used to fix the variable detector 1 to the outer circumferential surface of the inspection object P. When performing non-destructive inspection of the inspection object P using the variable detector 1, a radiation generating part (not shown) may be provided inside or outside the inspection object P.

[0096] In one embodiment, the main frame unit 60 may be connected to a main controller 90 via a connection cable 92. The main controller 90 transmits a control signal to the variable detector 1, and a radiation image acquired by the variable detector 1 may be transmitted to the main controller 90 for storage or processing.

[0097] Providing the main controller 90 separately from the variable detector 1 can reduce the weight and / or size of the variable detector 1. Providing the main controller 90 separately can also reduce radiation exposure to the main controller 90 and improve durability.

[0098] Since the variable detector 1 and the main controller 90 are connected via a connection cable 92, the variable detector 1 can be easily replaced and connected to the main controller 90 as required.

[0099] Referring to FIG. 12, a main controller 90 may be coupled to a server 94 or the like wirelessly or via a wired cable 96 .

[0100] Meanwhile, FIG. 13 is a cross-sectional view of another embodiment of a variable detector according to an embodiment of the present invention.

[0101] In contrast to Fig. 9, in the variable detector 1 shown in Fig. 13, the second protective panel 16 is provided in a state of being in close contact with the protective exterior 22 of the radiation detection unit 20. The second protective panel 16 may be attached to one side of the protective exterior 22 using an adhesive, or may be molded in a state in which the second protective panel 16 is attached together with the protective exterior 22 when it is injection molded using a double injection method. The embodiment shown in Fig. 13 has the effect of preventing foreign matter from entering between the second protective panel 16 and the protective exterior 22.

[0102] Fig. 14 is a diagram illustrating another embodiment of the detection panel section of the variable detector according to one embodiment of the present invention, showing a configuration in which a cushioning member is provided on the detection panel. Fig. 15 is a diagram illustrating a configuration in which a cushioning member is further provided between the first and second inner protection panels in another embodiment of the detection panel section of the variable detector according to one embodiment of the present invention. Fig. 16 is a diagram illustrating another embodiment of the detection panel section of the variable detector according to one embodiment of the present invention, showing an enlarged view of the cushioning member provided on the detection panel section.

[0103] FIG. 14(a) is an exploded perspective view showing the state in which the first buffer member 52a and the second buffer member 52b are attached to the detection panel 32, (b) is a diagram showing the state in which the first buffer member 52a and the second buffer member 52b are attached to the detection panel 32, (c) is a diagram showing the back of (b), and (d) is a cross-sectional view showing the layered structure of the buffer members.

[0104] 14, the detection panel 32 includes a variable TFT 33 and can detect X-rays. In one embodiment, the detection panel 32 is provided with a terminal 28 including an ROIC, a gate FPCB (Flexible Printed Circuit Board) 29, and a gate element 29a connected to the gate FPCB 29 and connected to the variable TFT 33. The gate element may be provided as a gate COF (Chip on Flex / Film). Meanwhile, the FPCB 29 and the gate element 29a in the detection panel 32 may be located on the other side in the longitudinal direction of the detection panel 32, unlike those shown in FIG. 14.

[0105] In the present invention, when the variable detector 1 is bent, the detection panel 32 is slid in the X-axis direction from between the first and second inner protective panels 34, 36. In order to buffer physical friction and impact applied to the detection panel 32, a first buffer member 52a may be attached along one side of the gate FPCB 29 of the detection panel 32, and a second buffer member 52a may be attached between the multiple gate elements 29a from the surface opposite to the first buffer member 52a.

[0106] The first buffer member 52a, the second buffer member 52b, and the third and fourth buffer members 52c and 52d described later may include an adhesive layer 54a, a cushion layer 54b, and a low-friction layer 54c, as shown in FIG. 14(d). The adhesive layer 54a is a layer for adhering to other members, the cushion layer 54b is a layer for cushioning by elastic deformation, and the low-friction layer 54c is a layer for reducing friction during sliding movement. The low-friction layer 54c is preferably made of a material with a small surface friction coefficient, and as an example, a sheet made of a resin such as polycarbonate may be used as the low-friction layer 54c. On the other hand, when the main function of the first buffer member 52a, the second buffer member 52b, the third buffer member 52c, and the fourth buffer member 52d is shock absorption or reduction, it is also possible to omit the low-friction layer 54c and provide only the adhesive layer 54a and the cushion layer 54b.

[0107] Referring to FIG. 15, a third buffer member 52c may be provided on the first inner protective panel 34. The third buffer member 52c may be formed to have a size corresponding to the variable TFT 33 of the detection panel 32. The third buffer member 52c is bonded to the first inner protective panel 34, and the low friction layer 54c of the third buffer member 52c faces the detection panel 32 side. Although FIG. 15 shows that the third buffer member 52c is provided on the first inner protective panel 34, the third buffer member 52c can also be attached to the second inner protective panel 36. In addition, a fourth buffer member 52d that maintains a gap between the first inner protective panel 34 and the second inner protective panel 36 while performing a buffering function may be further provided. The fourth buffer member 52d may be attached to either the first inner protective panel 34 or the second inner protective panel 36. In the present invention, the fourth buffer member 52d may also be referred to as a "buffer member for maintaining a gap."

[0108] 16, the first cushioning member 52a, the second cushioning member 52b, and the fourth cushioning member 52d are attached. In one embodiment, the second cushioning member 52b may be attached to one side of the first cushioning member 52a. The fourth cushioning member 52d is thicker than the other cushioning members 52a, 52b, and 52c in order to maintain a gap between the first inner protective panel 34 and the second inner protective panel 36.

[0110] The basic configuration of the variable detector 100 according to another embodiment of the present invention is the same as that of the variable detector 1 described above, so common features will be described briefly or omitted. The variable detector 100 according to another embodiment of the present invention includes a flexible panel unit 110, a main frame unit 160 coupled to one side of the panel unit 110, and an end frame unit 170 coupled to the other end of the panel unit 110.

[0112] The radiation detection unit 120 includes a detection panel unit 130 including a detection panel 132 therein, and a protective exterior 122 that encases the detection panel unit 130. A coupling portion 124 is formed on one side of the protective exterior 122, which is coupled to the main frame unit 160 on a first surface side, and a terminal 128 of the detection panel 132 can be exposed through an opening 126 formed in the coupling portion 124.

[0113] The main frame portion 160 includes a housing 162 and a control module 168 built into the housing 162, and may be provided with an inner cover 161 and an outer cover 163 that cover the open surface of the main frame portion 160. A sealing member for airtightness may be provided on the contact surfaces between the inner cover 161 and the housing 162.

[0114] The end frame part 170 is coupled to an end of the radiation detection part 120. A first sliding structure is formed in the end frame part 70. One side of the first protection panel 112 is fixed to the housing 162 of the main frame part 160, and the other side of the first protection panel 112 is coupled to the end frame part 170. The end frame part 170 includes an end frame body 172 and an end frame cover 176. The end frame body 172 and the end frame cover 176 are coupled to each other to form a space therebetween, and the stopper 180 is slidably coupled between the end frame body 172 and the end frame cover 176 while supporting the end of the first protection panel 112 using the stopper coupling hole 114 formed at the end of the first protection panel 112. The end frame part 170 further includes a lower cover 171, and a fixed end 117 formed at one end of the second protection panel 116 may be fixed between the end frame body 172 and the lower cover 171.

[0115] A detection panel unit 130 is provided inside the protective exterior 122 of the radiation detection unit 120. A connection piece 138a is provided on one side of the detection panel unit 130, and a plurality of fixing rods 139 may protrude from the connection piece 138a. The fixing rods 139 may be inserted into fixing rod insertion holes 124d formed in the connection part 124 of the protective exterior 122 in the Y-axis direction.

[0116] An inner end frame 140 and an inner end frame cover 150 are provided at the other end of the detection panel section 130. The other side of the detection panel provided inside the detection panel section 130 is slidable by a sliding structure between the inner end frame 140 and the inner end frame cover 150. The inner end frame 140 is fixed to the end frame section 170 side, and the fixing rod 139 is inserted into the fixing rod insertion hole 124d and fixed thereto, so that when the variable detector 100 is bent, the detection panel can slide in the X-axis direction inside the detection panel section 130 housed inside the protective exterior 122.

[0117] The variable detector 100 according to another embodiment of the present invention may further include a connection bracket 190 coupled to the end 123 side of the protective exterior 122. The connection bracket 190 may be provided in an L-shape with a first plate 192 coupled to the end frame part 170 and a second plate 194 coupled to the end 123 side of the protective exterior 122. The connection bracket 190 seals the opening on the end 123 side of the protective exterior 122, and can also mitigate impact applied to the radiation detection unit 120 when the variable detector 100 is accidentally detached and the end frame part 170 hits the ground first.

[0118] FIG. 20 is a diagram showing a cross section (cross section along the line BB' in FIG. 17) of a panel portion in a variable detector according to another embodiment of the present invention.

[0119] Referring to FIG. 20, the protective exterior 122 constituting the variable detector 100 may be provided with wings 200 on the first surface side to guide both sides of the first protective panel 112. In the present invention, when the variable detector 100 is bent, the first protective panel 112 may slide in the X-axis direction. The first wing 200a and the second wing 200b, which are bent from the outside to the inside, are provided on both ends along the X-axis direction on the first surface side of the protective exterior 122, and a protective panel guide space 202 is formed on the inside thereof, thereby guiding the sliding movement of the first protective panel 112. Although the first wing 200a and the second wing 200b are shown to extend along the X-axis direction on both ends of the first surface of the protective exterior 122, in the practice of the present invention, the first wing 200a and the second wing 200b may be provided at a predetermined interval in the X-axis direction. In addition, the first wing portion 200a and the second wing portion 200b are shown to partially cover both ends of the first protective panel 112, but the first wing portion 200a and the second wing portion 200b may extend to cover the entire upper surface of the first protective panel 112. In this case, the guide space 202 formed by the wings 200 has a flat tunnel structure that accommodates the first protective panel 112. Meanwhile, a protective panel coupling surface 204 to which the second protective panel 116 is coupled may be provided on the second surface side of the protective exterior 122 in a stepped manner.

[0120] Figure 21 is a plan view of the radiation detection section in a variable detector according to another embodiment of the present invention, Figure 22 is a diagram showing one side end (part D in Figure 19) of a variable detector according to another embodiment of the present invention with the detection panel section joined to the protective exterior, and Figure 23 is a diagram showing a cross section (cross section in the E-E' direction in Figure 22) of a variable detector according to another embodiment of the present invention with a connecting bracket joined to the end of the protective exterior.

[0121] 21, a connecting bracket 190 including a first plate 192 and a second plate 194 is coupled to an end portion 123 of a protective exterior 122 of a radiation detection unit 120. The connecting bracket 190 includes a first plate 192 and a second plate 194. As shown in FIG.

[0122] 22, an opening 125 may be formed on the end 123 side of the protective exterior 122. An inner end frame 140 coupled to an end of the detection panel unit 130 may be exposed through the opening 125. A fixing screw hole 141 may be formed in the inner end frame 140. In addition, a seal protrusion 127 may be formed around the opening 125.

[0123] 23, the connection bracket 190 can be fixed to the end 123 of the protective sheath 122 by inserting the fixing screw 196 through the second plate 194 of the connection bracket 190 and connecting it to the fixing screw hole 141 of the inner end frame 140. At this time, the sealing protrusion 127 is pressed, so that the opening 125 is sealed by the second plate 194, and the airtightness of the protective sheath 122 can be guaranteed. In one embodiment, the fixing screw 196 may be a screw having a waterproof function, and a sealing member such as a gasket or an O-ring may be used in place of the sealing protrusion 127 or in parallel with the sealing protrusion 127. In addition, since the inner end frame 140 is fixed to the end frame part 170 through the connection bracket 190, the detection panel can slide inside the detection panel part 130 when the variable detector 100 is bent.

[0124] Meanwhile, it has been explained that the connecting bracket 190 is connected to the end 123 of the protective exterior 122 and the seal protrusion 127 is pressed. However, in the implementation of the present invention, if the connecting bracket 190 is not provided, it is also possible that the end 123 of the protective exterior 122 is directly connected to the end frame portion 170 and the seal ring protrusion 127 is pressed to seal the opening 125.

[0125] FIG. 24 is a cross-sectional view (cross-section along CC' in FIG. 17) showing a variable detector in a coupled state according to another embodiment of the present invention.

[0126] A second plate 194 of the connecting bracket 190 is coupled to the end 123 side of the protective exterior 122, and a first plate 192 of the connecting bracket 190 is coupled between the end frame body 172 of the end frame part 170 and the lower cover 171. The second plate 194 of the connecting bracket 190 is fixed to the inner end frame 140 of the detection panel part 130 by the fixing screw 196 described above, and presses the seal protrusion 127.

[0127] One side of the first protective panel 112 is slidably connected between the end frame body 172 and the end frame cover 176, and the second protective panel 116 is connected to the lower surface of the protective exterior 122, while one side of the second protective panel 116 is connected between the end frame body 172 and the lower cover 171 of the end frame portion 170.

[0128] 24, a gap G may be formed between the second plate 194 of the connecting bracket 190 and the end frame main body 172. Due to the elasticity of the gap G and the connecting bracket 190, it is possible to reduce the impact applied to the radiation detection unit 120 when the variable detector 100 is dropped with the end frame part 170 facing downward.

[0129] FIG. 25 is a diagram showing another embodiment of an end frame portion in a variable detector according to another embodiment of the present invention.

[0130] In the embodiment shown in FIG. 25, the connecting bracket 190 is not provided, and the end 123 of the protective sheath 122 is directly coupled to the end frame body 172 of the end frame part 170. In one embodiment, the end frame body 172' is formed with a concave receiving part as shown in FIG. 25, and the end 123 of the protective sheath 122 is inserted into the receiving part. The end frame body 172' is formed with a screw insertion hole 173 formed along the longitudinal direction (X-axis direction in FIG. 17) of the variable detector 100. A separate fixing screw is inserted through the screw insertion hole 173 and coupled to the fixing screw hole 141 of the inner end frame 140 of the detection panel part 130, so that the end 123 of the protective sheath 122 and the inner end frame 140 can be fixed to the end frame body 172'. Thereafter, a sealing cover 175 is attached to the surface of the end frame body 172' where the screw insertion hole 173 is exposed, so that airtightness can be maintained.
