Description

Technology Field

Background Technology

[0002] Non-destructive testing refers to a method of inspecting the material, performance, condition, and presence or absence of defects without destroying the object being inspected. By using non-destructive testing methods, internal structures or defects can be identified without destroying the object being inspected. Examples include quality inspection of various industrial products in industrial settings, verification of defects in buildings, and checking for wear and corrosion conditions.

[0003] Among the above non-destructive testing methods, when performing non-destructive testing using X-rays, a hollow cylindrical object, such as a pipe, can be used as the inspection target. Meanwhile, a structure or method is required that can easily measure the dimensions (e.g., radius, etc.) of the inspection target captured during the non-destructive testing without the need for a separate measuring device.

[0004] However, the variable detector is bent to wrap around the outer surface of the object being inspected, and as the variable detector is bent, stress may occur between the parts of the variable detector forming a layered structure, or tensile force may be applied to the radiation detection panel, causing damage.

[0005] In addition, the X-ray detection panel and electrical components installed inside the variable detector need to block the ingress of external foreign substances such as moisture or dust. Prior art literature

Specific details for implementing the invention

[0044] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the present invention, such detailed description is omitted. Additionally, while preferred embodiments of the present invention will be described below, the technical concept of the present invention is not limited or restricted thereto and can be modified and implemented in various ways by those skilled in the art. Moreover, the various embodiments of the present invention described below can be combined with one another.

[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 a variable detector according to an embodiment of the present invention. In addition, FIG. 4 is a drawing for explaining a first slide structure in a variable detector according to an embodiment of the present invention.

[0046] In the following embodiments, the X-axis direction represents the first direction (length direction), the Y-axis direction represents the second direction (width direction) perpendicular to the first direction, and the Z-axis direction represents the vertical direction (thickness direction) as a direction perpendicular to both the first direction and the second direction. Additionally, the XY plane formed by the X-axis and the Y-axis represents a horizontal plane, and the XZ plane formed by the X-axis and the 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 section (10) is composed of a plurality of panels stacked together and can be bent to surround the outer surface of the object to be inspected. A radiation detector (20) capable of detecting radiation is provided inside the panel section (10).

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

[0050] The end frame portion (70) is connected to the panel portion (10) on the opposite side of the main frame portion (60). The end frame portion (70) may be made of a non-elastic material or a material with greater rigidity than the panel portion (10).

[0051] Referring to FIGS. 2 and FIGS. 3, the detailed configuration and connection configuration of the panel section (10), the main frame section (60), and the end frame section (70) are shown. In FIGS. 2 and FIGS. 3, the connection between the components may be made using screws or adhesives. Since this method of connecting components is a conventional means, please note that, except in special cases in the present invention, a detailed description of means such as the use of screws or adhesives for connecting components is omitted.

[0052] The panel section (10) may include a radiation detection section (20) and a first protective panel (12) and a second protective panel (16) respectively provided on the first and second surfaces of the radiation detection section (20). In one embodiment, one side of the first protective panel (12) may be fixed to the main frame section (60), and one side of the second protective panel (16) may be fixed to the main frame section (60) with the radiation detection section (20) in between.

[0053] The radiation detection unit (20) may be configured to include a detection panel unit (30) that includes a detection panel (32) inside. In one embodiment, the radiation detection unit (20) may include a protective outer casing (22) that encloses the detection panel unit (30). The protective outer casing (22) may be made of a flexible material and may function as a housing that accommodates the detection panel unit (30). The protective outer casing (22) may be made of rubber, urethane, silicone, carbon composite material, or plastic, etc., which allow radiation to pass through and whose shape is variable. In one embodiment, the protective outer casing may be made of silicone rubber. Since the detection panel (32) inside is enclosed by the protective outer casing (22), waterproof and dustproof performance may be improved.

[0054] Referring to FIG. 2, a coupling part (24) that is coupled to a main frame part (60) on a first side may be formed on one side of the radiation detection part (20). In one embodiment, the coupling part (24) includes a first opening part (26), and a terminal (28) of the detection panel (32) may be exposed through the first opening part (26).

[0055] In one embodiment, the protective outer casing (22) may be configured such that the remaining parts, excluding the first opening (26), are sealed directly or indirectly. The detection panel (32) may be housed inside the protective outer casing (22) and protected from moisture or dust.

[0056] The first protective panel (12) and the second protective panel (16) are located on the upper surface (first surface) and lower surface (second surface) of the radiation detection unit (20), and may be composed of rubber, urethane, silicone, carbon composite material, or plastic, which are permeable to radiation and have a variable shape. In one embodiment, the first protective panel (12) and the second protective panel (16) may be made of carbon fiber reinforced plastic (CFRP). The second protective panel (16) is exemplified as being coupled to the lower surface of the radiation detection unit, but the second protective panel (16) may also be attached to the lower surface of the protective outer casing (22) of the radiation detection unit (20) using an adhesive or double-sided tape. In addition, depending on the case, when injection molding the protective outer casing (22), it is also possible to manufacture the protective outer casing (22) and the second protective panel (16) as a single combined body by including the second protective panel (16) on one side of the protective outer casing (22) using an insert injection method.

[0057] The main frame section (60) may include a housing (62) and a control module (68) embedded in the housing (62). The control module (68) may include electronic components and circuits for controlling the detection panel (32) and / or processing the detection signal of the detection panel (32). In one embodiment, the control module (68) may be configured as a printed board assembly (PBA).

[0058] Referring to FIG. 3, the main frame portion (60) includes a second opening (66) on its bottom surface and can communicate with the first opening (26) of the radiation detection portion (20) through the second opening (66). In one embodiment, the terminal (28) of the detection panel (32) provided in the radiation detection portion (20) can be connected to the control module (68) through the first opening (26) and the second opening (66). However, in the implementation of the present invention, the first opening and the second opening must not necessarily be provided in the radiation detection portion (20) and the main frame portion (60), and it may also be possible for the detection panel portion to be connected to the control module (68) of the main frame portion (60) through a separate connector.

[0059] The end frame portion (70) is coupled to the end of the radiation detector portion (20). The end frame portion (70) can be attached to the end of the radiation detector portion (20) with adhesive or fixed using a fixing screw. A first slide structure, which will be described later, is formed on the end frame portion (70).

[0060] One side of the first protective panel (12) is fixed to the housing of the main frame part (60), and the other side of the first protective panel (12) is coupled to the end frame part (70). The other side of the first protective panel (12) is coupled to the end frame part (70) to form a first slide structure, so that when the panel part (10) is deformed, the end of the first protective panel (12) can slide within a predetermined range through the first slide structure.

[0061] Referring to FIGS. 2 to 4, the first slide structure may be composed of an end frame part (70) and a stopper (80).

[0062] The end frame section (70) includes an end frame body (72) and an end frame cover (76). The end frame body (72) is coupled to the end of the radiation detection section (20), and the end frame cover (76) can be coupled to the first surface of the end frame body (72). The end frame body (72) and the end frame cover (76) are coupled to form a spaced-apart space between them, and a stopper (80) is slidably coupled between the end frame body (72) and the end frame cover (76).

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

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

[0065] One of the first slide projection (83a) or the second slide projection (83b) can be inserted into the stopper coupling hole (14) of the first protective panel (12) so that the end of the first protective panel (12) can be slidably coupled to the end frame part (70).

[0066] In the implementation of the present invention, the slide guide may be provided with only one of the first slide guide (74) or the second slide guide (78), and the slide projection may also be provided with only one of the first slide projection (83a) or the second slide projection (83b) corresponding to the slide guide.

[0067] The stopper (80) is slidable in the X-axis direction by the slide projections (83a, 83b) being 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 slidable limit position or distance is set to limit the maximum allowable bending degree of the variable detector (1).

[0068] Meanwhile, although FIGS. 2 to 4 illustrate the stopper (80) being configured separately from the first protective panel (12), in the implementation of the present invention, it may also be possible to form the stopper (80) integrally with the first protective panel (12). Furthermore, it goes without saying that the stopper (80) can be implemented in various modified 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 the second side of the radiation detector (20). One side of the second protective panel (16) is coupled to the radiation detector (20) through the lower side of the housing (62) of the main frame part (60). The other side of the second protective panel (16) is coupled to the end frame part (70).

[0070] One end of the first protective panel (12) is fixed to the housing (62) of the main frame part (60), and the other end of the first protective panel (12) is slidably coupled to the end frame part (70) by the first slide structure. In contrast, both ends of the second protective panel (16) are fixed to the lower side of the housing (62) of the main frame part (60) and the end frame part (70). With this configuration, when the panel part (10) is bent, both ends of the second protective panel (16) do not slide, and one end of the first protective panel (12) can slide by the first slide structure. However, in the implementation of the present invention, it is also possible to provide the first slide structure to the second protective panel (16), or to fix both ends of the first protective panel (12) and form the first slide structure on the second protective panel (16).

[0071] Meanwhile, since the second protective panel (16) is made of a flexible material, when one end of the second protective panel (16) is fixed to the housing side of the main frame part (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 drawings show that the radiation detector (20), main frame (60), first protection panel (12), second protection panel (16) and end frame (70) are joined using screws, it is also possible to join them using adhesive.

[0073] FIG. 5 is an exploded view of the radiation detection unit and end frame of a variable detector according to one embodiment of the present invention, and FIG. 6 is a perspective view of the detection panel unit with the protective outer casing removed from the radiation detection unit in the variable detector according to one embodiment of the present invention. In addition, FIG. 7 is an exploded perspective view of the detection panel unit in the variable detector according to one embodiment of the present invention.

[0074] As described above, the radiation detection unit (20) illustrated in FIG. 5 includes a protective outer casing (22), and the end frame body (72) of the end frame unit (70) is coupled to the end of the radiation detection unit (20). As described above, the protective outer casing (22) is provided with a first opening (26) into which a detection panel unit (30) is inserted and a terminal (28) of the detection panel (32) is exposed. A waterproof protrusion (24a, 24b) may be formed on the coupling unit (24) surrounding the first opening (26) to improve waterproof performance. It is also possible to provide a plurality of waterproof protrusions (24a, 24b), including a first waterproof protrusion (24a) and a second waterproof protrusion (24b) that surround the first opening (26). Additionally, a screw hole (24c) may be formed in the coupling portion (24) of the first opening (26) so that the coupling portion (24) can be coupled to the bottom surface of the housing (62). Additionally, a fixing rod insertion hole (24d) may be provided in a part of the coupling portion (24). One end of the detection panel portion (30) may be fixed through the fixing rod insertion hole (24d). In one embodiment, a fixing rod may be formed protruding from the first coupling piece (38a) described later, and one side of the detection panel portion (30) may be fixed near the first opening (26) of the protective outer casing (22) by inserting the fixing rod into the fixing rod insertion hole (24d).

[0075] Referring to FIGS. 6 and 7, a detection panel section (30) is provided inside the protective outer casing (22) of the radiation detection section (20). The detection panel section (30) includes a detection panel (32) and a first inner protective panel (34) and a second inner protective panel (36) provided on the first and second surfaces, respectively, of the detection panel (32).

[0076] The detection panel (32) may be formed of a flexible material. For example, the detection panel (32) may be configured to include a variable TFT (flexible thin film transistor) (33), and image information can be obtained by converting light emitted by a fluorescent material in response to radiation transmitted through the inspection target into an electrical (charge) signal.

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

[0078] The first and second inner protective panels (34, 36) may be made of a radiation-transmitting flexible material. The first and second inner protective panels (34, 36) may perform the function of protecting the detection panel (32).

[0079] The connecting piece (38) includes a first connecting piece (38a) and a second connecting piece (38b), and the first connecting piece (38a) and the second connecting piece (38b) can be connected by screws or the like to assemble one side of the detection panel part (30). In addition, a third connecting piece (38c) may be provided between the first connecting piece (38a) and the second connecting piece (38b). In one embodiment, the third connecting piece (38c) may be located between the first and second inner protective panels (34, 36).

The inner end frame body (42) includes a plate (44) having a guide projection (45) formed protrudingly and a wall section (46) formed on the side of the plate (44). The inner end frame cover (50) may be coupled to the inner frame body (42) by being coupled by screws to the upper part of the wall section (46) and the upper part of the guide projection (45). This inner end frame section (40) is provided on the end side of the detection panel section (30) on the side of the aforementioned end frame section (70).

[0081] A slide panel (48) may be provided between the inner end frame body (42) and the inner end frame cover (50). In one embodiment, one side of the detection panel (32) may be fixed to the third coupling piece (38c) through the first fixing part (33a), and the other side of the detection panel (32) may be fixed to the slide panel (48) through the second fixing part (33b). The first and second fixing parts (33a, 33b) may be formed using an adhesive or an adhesive film.

[0082] First and second slide slots (35, 37) are formed in the first and second inner protective panels (34, 36), respectively, and a third slide slot (49) is formed in the slide panel (48). A guide projection (45) formed on the inner end frame body (42) is inserted into the second slide slot (37) formed in the second inner protective panel (36), the third slide slot (49) formed in the slide panel (48), and the first slide slot (35) formed in the first inner protective panel (34). This configuration constitutes a second slide structure (in the present invention, the second slide structure is also referred to as an “inner slide structure”). When the detection panel section (30) is bent, the ends of the first and second inner protective panels (34, 36) slide with the guide projection (45) inserted into the first and second slide slots (35, 37). Additionally, since the end of the detection panel (32) is fixed to the slide panel (48), when the detection panel section (30) is bent, the slide panel (48) slides with the guide projection (45) inserted into the third slide slot (49) of the slide panel (48), thereby enabling the detection panel (32) to slide in the X-axis direction.

[0083] When the variable detector (1) according to the present invention is bent with respect to the inspection target, the operation of the slide structure provided in the variable detector (1) is described.

[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 in the AA' direction of FIG. 8) illustrating the operating state of a slide 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 same direction as 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 protection panel (12) is positioned in a neutral position with the slide projections (83a, 83b) inserted into the slide guides (74, 78) formed in the end frame body (72) and the end frame cover (76). Additionally, the end of the detection panel (32) is fixed to the slide panel (48), and the respective ends of the first and second inner protection panels (34, 36) are positioned in a neutral position in the space between the inner end frame body (42) and the inner end frame cover (50) of the inner end frame part (40). A guide projection (45) protruding from the end frame body (42) is inserted into the slide slots (49, 35, 37) formed in the slide panel (48) and the first and second inner protection panels (34, 36), respectively. Here, the neutral position can be understood as the position of the stopper (80) and the respective ends of the slide panel (48) and the first and second inner protection panels (34, 36) when the variable detector (1) is not bent.

[0087] When the variable detector (1) is bent as in FIG. 9(b), the stopper (80) coupled to the end of the first protection panel (12) is moved to a first position with the slide projections (83a, 83b) inserted into the slide guides (74, 78) formed on the end frame body (72) and the end frame cover (76). The moving position of the stopper (80) is determined by the degree of bending of the variable detector (1), and the maximum moving distance is limited by the slide guides (74, 78) (i.e., there is a limit point of the first position). By limiting the maximum moving distance of the stopper (80), excessive deformation of the variable detector (1) is prevented. Additionally, the end of the detection panel (32) is fixed to the slide panel (48), and the respective end of the first and second inner protection panels (34, 36) moves to a respective first position 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 as the position of the stopper (80), the slide panel (48), and the respective end of the first and second inner protection panels (34, 36) when the variable detector (1) is in a bent state.

[0088] With this slide structure, the tensile force applied to the detection panel (32) during bending of the variable detector (1) can be minimized.

[0089] FIG. 10 is a cross-sectional view (cross-section in the AA' direction of FIG. 8) illustrating another embodiment of a slide structure according to the bending state of a variable detector according to one embodiment of the present invention.

[0090] In FIG. 10, the difference is that the length of the slide guides (74, 78) formed on the end frame body (72) and the end frame cover (76) is extended further to the left compared to FIG. 9, while the other components 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 a bent state by applying force as in FIG. 8, FIG. 10 (c) shows the variable detector (1) in a bent state opposite to FIG. 10 (b) by applying force in the opposite direction to the force shown in FIG. 8.

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

[0093] Meanwhile, in FIG. 10 (b) and (c), it can be seen that the end of the detection panel (32) is fixed to the slide panel (48) and the end of the first and second inner protection panels (34, 36) slides and moves according to the bending of the variable detector (1).

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

[0095] Referring to FIG. 11, the variable detector (1) can be mounted along the outer surface of the object to be inspected (P). To secure the variable detector (1) to the outer surface of the object to be inspected (P), a fixing part (2) consisting of a band, string, wire, belt, ratchet belt, chain, Velcro, etc. may be used. When performing a non-destructive inspection of the object to be inspected (P) using the variable detector (1), a radiation generating part not shown may be provided on the inner or outer side of the object to be inspected (P).

[0096] In one embodiment, the main frame unit (60) may be connected to the main controller (90) via a connecting cable (92). The main controller (90) can transmit a control signal to the variable detector (1) and receive and store or process the radiation image acquired from the variable detector (1).

[0097] By providing the main controller (90) separately from the variable detector (1), the weight and / or size of the variable detector (1) can be reduced. Additionally, providing the main controller (90) separately can 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 connecting cable (92), the variable detector (1) can be easily replaced and connected to the main controller (90) as needed.

[0099] Referring to FIG. 12, the main controller (90) can be connected to a server (94) or the like via a wireless or wired cable (96).

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

[0101] Compared to FIG. 9, in the variable detector (1) illustrated in FIG. 13, a second protective panel (16) is provided in a state of being in close contact with the protective outer casing (22) of the radiation detection unit (20). The second protective panel (16) can be attached to one side of the protective outer casing (22) using an adhesive, or the second protective panel (16) can be formed together with the protective outer casing (22) when injection molding the protective outer casing (22) using a double injection method. In the case of the embodiment illustrated in FIG. 13, there is an effect of preventing foreign matter from entering between the second protective panel (16) and the protective outer casing (22).

[0102] FIG. 14 illustrates another embodiment of the detection panel portion of a variable detector according to one embodiment of the present invention, showing a configuration in which a buffer member is provided in the detection panel. FIG. 15 illustrates another embodiment of the detection panel portion of a variable detector according to one embodiment of the present invention, showing a configuration in which a buffer member is additionally provided between the first and second inner protection panels. FIG. 16 illustrates another embodiment of the detection panel portion of a variable detector according to one embodiment of the present invention, showing an enlarged view of the buffer member provided in the detection panel portion.

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

[0104] Referring to FIG. 14, the detection panel (32) may include a variable TFT (33) to 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 of the longitudinal direction of the detection panel (32), unlike as shown in FIG. 14.

[0105] In the present invention, when the variable detector (1) is bent, the detection panel (32) slides in the X-axis direction between the first and second inner protection panels (34, 36). In order to cushion physical friction or impact applied to the detection panel (32), a first cushioning member (52A) is attached along one side of the gate FPCB (29) of the detection panel (32), and a second cushioning member (52B) may be attached between a plurality of gate elements (29a) on the opposite side of the first cushioning member (52A).

[0106] The first cushioning member (52A), the second cushioning member (52B), and the third and fourth cushioning members (52C, 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 bonding to other members, the cushion layer (54b) is a layer for cushioning through 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 low 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). Meanwhile, in the case where the primary function of the first cushioning member (52A), the second cushioning member (52B), the third cushioning member (52C), and the fourth cushioning member (52D) is shock absorption or mitigation, 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 cushioning member (52C) ​​may be provided on the first inner protective panel (34). The third cushioning member (52C) ​​may be formed to have a size corresponding to the variable TFT (33) of the detection panel (32). The third cushioning member (52C) ​​is attached to the first inner protective panel (34), and the low-friction layer (54c) of the third cushioning member (52C) ​​faces toward the detection panel (32). Although FIG. 15 illustrates the third cushioning member (52C) ​​being provided on the first inner protective panel (34), the third cushioning member (52C) ​​may also be attached to the second inner protective panel (36). Additionally, a fourth cushioning member (52d) may be further provided to maintain the gap between the first inner protective panel (34) and the second inner protective panel (36) while performing a cushioning function. The fourth cushioning 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 cushioning member (52d) is also referred to as a 'gap-maintaining cushioning member'.

[0108] Referring to FIG. 16, the state in which the first cushioning member (52a), the second cushioning member (52b), and the fourth cushioning member (52d) are attached can be seen. In one embodiment, the second cushioning member (52b) may be attached to one side of the first cushioning member (52a). Since the fourth cushioning member (52d) maintains the gap between the first inner protective panel (34) and the second inner protective panel (36), the fourth cushioning member (52d) has a greater thickness compared to the other cushioning members (52a, 52b, 52c).

[0109] FIG. 17 is a perspective view of a variable detector according to another embodiment of the present invention, FIG. 18 is an exploded perspective view of a variable detector according to another embodiment of the present invention, and FIG. 19 is an exploded perspective view of a radiation detection unit in a variable detector according to another embodiment of the present invention.

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

[0111] The panel section (110) may include a radiation detection section (120) and a first protection panel (112) and a second protection panel (116) respectively provided on the first surface (upper surface) and the second surface (lower surface) of the radiation detection section (120).

[0112] The radiation detection unit (120) includes a detection panel unit (130) containing a detection panel (132) inside, and a protective outer casing (122) that surrounds the detection panel unit (130). On one side of the protective outer casing (122), a coupling unit (124) is formed that is coupled to a main frame unit (160) on the first side, and a terminal (128) of the detection panel (132) can be exposed through an opening (126) formed in the coupling unit (124).

[0113] The main frame portion (160) includes a housing (162) and a control module (168) embedded in 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 surface between the inner cover (161) and the housing (162).

[0114] The end frame portion (170) is coupled to the end of the radiation detection portion (120). A first slide structure is formed in the end frame portion (70). One side of the first protection panel (112) is fixed to the housing (162) of the main frame portion (160), and the other side of the first protection panel (112) is coupled to the end frame portion (170). The end frame portion (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 form a spaced-apart space between them, 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 a stopper coupling hole (114) formed at the end of the first protection panel (112). The end frame portion (170) further includes a lower cover (171), and a fixed end (117) formed at one end of the second protective panel (116) can be fixed between the end frame body (172) and the lower cover (171).

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

[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 end of the detection panel provided inside the detection panel section (130) can slide by means of a slide 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 a fixing rod (139) is inserted into the fixing rod insertion hole (124d) and fixed, so that when the variable detector (100) is bent, the detection panel inside the detection panel section (130) housed inside the protective outer casing (122) can slide in the X-axis direction.

[0117] A variable detector (100) according to another embodiment of the present invention may further include a connecting bracket (190) coupled to the end (123) side of the protective outer casing (122). The connecting bracket (190) may be provided with a first plate (192) coupled to the end frame part (170) side and a second plate (194) coupled to the end (123) side of the protective outer casing (122) in an L-shape. The connecting bracket (190) seals the opening on the end (123) side of the protective outer casing (122), while mitigating the impact applied to the radiation detection part (120) in the event that the variable detector (100) accidentally falls and the end frame part (170) side touches the ground first.

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

[0119] Referring to FIG. 20, the protective outer casing (122) forming the variable detector (100) may be provided with wing portions (200) on the first side that 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. By providing a first wing portion (200a) and a second wing portion (200b) that bend from the outside to the inside at both ends along the X-axis direction on the first side of the protective outer casing (122), and forming a protective panel guide space (202) inside, the sliding movement of the first protective panel (112) can be guided. Although the first wing portion (200a) and the second wing portion (200b) are depicted as extending along the X-axis direction at both ends of the first surface of the protective outer casing (122), in the embodiment of the present invention, the first wing portion (200a) and the second wing portion (200b) may also be provided at predetermined intervals in the X-axis direction. Additionally, although the first wing portion (200a) and the second wing portion (200b) are depicted as partially covering both ends of the first protective panel (112), it is also possible for the first wing portion (200a) and the second wing portion (200b) to be extended to completely cover the upper surface of the first protective panel (112). In this case, the guide space (202) formed by the wing portion (200) will be a flat tunnel structure that accommodates the first protective panel (112). Meanwhile, on the second side of the protective outer casing (122), a protective panel joining surface (204) to which a second protective panel (116) is joined may be provided with a step.

[0120] FIG. 21 is a plan view of a radiation detection unit in a variable detector according to another embodiment of the present invention, FIG. 22 is a drawing showing one end (part D in FIG. 19) in a state where a detection panel unit is coupled to a protective outer casing in a variable detector according to another embodiment of the present invention, and FIG. 23 is a drawing showing a cross-section (cross-section in the EE' direction in FIG. 22) in which a connecting bracket is coupled to an end of a protective outer casing in a variable detector according to another embodiment of the present invention.

[0121] Referring to FIG. 21, a connecting bracket (190) including a first plate (192) and a second plate (194) is coupled to the end (123) side of the protective outer casing (122) of the radiation detector (120).

[0122] Referring to FIG. 22, an opening (125) may be formed on the end (123) side of the protective outer casing (122). Through the opening (125), an inner end frame (140) coupled to the end of the detection panel part (130) may be exposed. A fixing screw hole (141) may be formed in the inner end frame (140). Additionally, a sealing projection (127) may be formed around the opening (125).

[0123] Referring to FIG. 23, the connecting bracket (190) can be fixed to the end (123) side of the protective outer casing (122) by inserting a fixing screw (196) through the second plate (194) of the connecting bracket (190) and connecting it to the fixing screw hole (141) of the inner end frame (140). At this time, the opening (125) is sealed by the second plate (194) by pressing the sealing projection (127), and the airtightness of the protective outer casing (122) can be ensured. In one embodiment, the fixing screw (196) may be a screw having a waterproof function, and it is also possible to use a sealing member such as a gasket or an O-ring to replace or in parallel with the sealing projection (127). In addition, since the inner end frame (140) is fixed to the end frame section (170) side through the connecting bracket (190), the detection panel can slide inside the detection panel section (130) when the variable detector (100) is bent.

[0124] Meanwhile, although it has been described that a connecting bracket (190) is coupled to the end (123) of the protective outer casing (122) and the sealing projection (127) is pressed, in the embodiment of the present invention, if the connecting bracket (190) is not provided, it is also possible for the end (123) of the protective outer casing (122) to be directly coupled to the end frame portion (170) and for the sealing projection (127) to be pressed so that the opening (125) is sealed.

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

[0126] The second plate (194) of the connecting bracket (190) is attached to the end (123) side of the protective outer casing (122), and the first plate (192) of the connecting bracket (190) is attached 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 aforementioned fixing screw (196) and presses the sealing projection (127).

[0127] One side of the first protective panel (112) is slidably coupled between the end frame body (172) and the end frame cover (176), and the second protective panel (116) is coupled to the lower surface of the protective outer casing (122), while one side of the second protective panel (116) is coupled between the end frame body (172) and the lower cover (171) of the end frame part (170).

[0128] As illustrated in FIG. 24, the second plate (194) of the connecting bracket (190) can form a gap (G) between it and the end frame body (172). Due to the gap (G) and the elasticity of the connecting bracket (190), the impact applied to the radiation detection unit (120) can be mitigated when the variable detector (100) falls downward with the end frame part (170).

[0129] FIG. 25 is a drawing illustrating another embodiment of the end frame portion of a variable detector according to another embodiment of the present invention.

[0130] In the embodiment illustrated in FIG. 25, the connecting bracket (190) is not provided, and the end (123) of the protective outer casing (122) is directly connected to the end frame body (172) of the end frame part (170). In one embodiment, a concave receiving portion as illustrated in FIG. 25 is formed in the end frame body (172'), and the end (123) of the protective outer casing (122) is inserted into the receiving portion. The end frame body (172') has a screw insertion hole (173) formed along the longitudinal direction (X-axis direction in FIG. 17) of the variable detector (100). By inserting a separate fixing screw through the screw insertion hole (173) and connecting it to the fixing screw hole (141) of the inner end frame (140) of the detection panel part (130), the end (123) of the protective outer casing (122) and the inner end frame (140) can be fixed to the end frame body (172'). Subsequently, a sealing cover (175) is attached to the surface of the end frame body (172') where the screw insertion hole (173) is exposed to maintain airtightness.
