Description

Technical Field

[0001] The invention relates to the technical field of irradiation experiments, and in particular to a block-type irradiation environment test box. Background Art

[0002] During the early stages of development, certain nuclear power plant equipment requires gamma ray testing in high-temperature environments. This high temperature necessitates the use of an environmental test chamber, which houses a heating device to raise the internal temperature to the required level. The chamber is constructed from a combination of metal and insulation materials, allowing gamma rays to penetrate and irradiate the equipment within.

[0003] Existing environmental test chambers are integrated, box-like structures that can only accommodate equipment smaller than their size. Larger equipment requires a larger environmental test chamber, which in turn requires a larger footprint. Irradiation source suppliers are not solely focused on radiation resistance testing for nuclear power plant equipment; they also handle a variety of other projects, such as irradiation sterilization of prepared meals. Given the large footprint of environmental test chambers, managing unused chambers poses a significant challenge for these companies. Summary of the Invention

[0025] Step S13: Place the door connector at the inner corner of the tail box module, with the end of the door connector extending out of the tail box module and into the door, and also located at the inner corner of the door, and plug the door connector into the adjacent module connector;

[0026] Step S14: Connect the box door, box module and module connector with bolts.

[0027] As a preferred technical solution, it also includes a mover arranged at the bottom of the box door;

[0028] The mover includes a moving frame, which is rotatably connected to a pulley shaft. Both ends of the pulley shaft are connected to pulleys through pulley mounting frames. The pulley mounting frames can rotate with the pulley shaft so that the pulley mounting frames are located in a vertical or horizontal direction, thereby controlling the pulley to be located below the moving frame or on one side of the moving frame; the pulley shaft is connected to a rotating handle.

[0029] As an optimal technical solution, the pulley shaft is connected to the rotating handle through a transmission structure, and the transmission structure includes a driven gear I set on the pulley shaft and a driving gear I set on the drive shaft I; the drive shaft I is connected to the rotating handle.

[0030] As an optimal technical solution, the pulley shaft is a telescopic shaft.

[0031] The telescopic shaft includes an inner telescopic shaft and an outer telescopic shaft. The inner telescopic shaft is coaxially connected to the outer telescopic shaft at both ends via a limiting structure, allowing the outer telescopic shaft to move linearly along the inner telescopic shaft but unable to rotate relative to the inner telescopic shaft.

[0032] The ends of the two telescopic outer shafts are connected with pulleys through pulley mounting frames, and the telescopic inner shaft is coaxially provided with the above-mentioned driven gear I.

[0033] A connecting block is sleeved on each of the two telescopic outer shafts, and a nut is connected to one side of the connecting block. The two nuts are respectively sleeved on a screw, and the thread teeth of the two nuts are in opposite directions; the screw is provided with a cylindrical section, on which a driven gear II is coaxially provided, and the screw rotates following the driven gear II; the driven gear II meshes with the driving gear II, and the driving gear II is coaxially arranged on the drive shaft II, and the drive shaft II is connected to a rotating handle.

[0034] As a preferred technical solution, the rotating handle includes a rotating end, an optical axis, and a limiting end; the rotating end and the limiting end are respectively located at the two ends of the optical axis; an optical axis channel is provided on the drive shaft II for the optical axis to pass through, so that the rotating end and the limiting end are also respectively located at the two ends of the drive shaft II; the limiting end is also located between the drive shaft II and the drive shaft I; the length of the optical axis is greater than the length of the drive shaft II; the sides of the drive shaft I and the drive shaft II facing the limiting end are both provided with limiting grooves, and the optical axis can be moved so that the limiting end is located in any limiting groove, and the limiting end and the limiting groove are both square structures. When the limiting end is located in the limiting groove of the drive shaft I, the rotating handle controls the drive shaft I; when the limiting end is located in the limiting groove of the drive shaft II, the rotating handle controls the drive shaft II.

[0035] As an optimal technical solution, a mounting groove is provided at the bottom of the box door, and the movable frame is embedded in the mounting groove, with the bottom of the movable frame flush with the bottom of the box door; and the side of the movable frame is flush with the side of the box door.

[0036] Compared with the existing technology, it has the following beneficial effects:

[0037] In the present invention, a box body is assembled using box modules with a foldable rectangular structure, so that the overall structure can be disassembled and assembled, which is convenient for storage after disassembly when not in use, thereby reducing the floor space occupied; and multiple box body modules can be selected in appropriate numbers according to the required size, thereby facilitating the adjustment of the volume of the box body to accommodate devices of different sizes to be tested.

[0038] In the present invention, L-shaped module connectors are used to fix the four corners of the box module, so that the box module maintains a stable rectangular state, and any two adjacent box modules are connected by the same module connector, which increases the stability of the connection and also increases the connection strength of the box module.

[0039] In the present invention, the door connector is smaller than the module connector, which means that the overall width of the door is smaller than the box module, so as to ensure that the volume of the non-foldable door is relatively small.

[0040] The structure of the mover in this invention allows the pulleys to be located below the mobile frame for easy movement, or on the side of the mobile frame, ensuring the stability of the entire test chamber during operation. The pulley spacing is adjustable to facilitate alignment with the radiation system's track. The same rotary handle allows for both pulley spacing and position control across different systems, saving overall structural space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0050] On the contrary, this application covers any alternatives, modifications, equivalents, and solutions made within the spirit and scope of this application as defined by the claims. Furthermore, to facilitate a better understanding of this application, certain specific details are described in detail below in the detailed description of this application. Those skilled in the art will be able to fully understand this application without these details.

[0051] Example 1: Figure 1-Figure 2 As shown, a modular irradiation environment test box includes a box body and a box door 7. The box body is a rectangular cavity structure, and the box door 7 is arranged at both ends of the box body to close the cavity structure.

[0052] The box consists of a box module and module connectors 4. The box module consists of two vertical panels 2 and two horizontal panels 1. The vertical panels 2 are hinged at their tops and bottoms to the horizontal panels 1 via hinges 3, forming a foldable rectangular structure. The hinges 3 allow the box module to be easily unfolded into a rectangular shape or folded flat. Once folded flat, the box module is easily stored.

[0053] A slot is provided on one end wall of the box module, and an inserting block that matches the slot of the adjacent box module is provided on the other end wall of the box module.

[0054] The end walls of the box body refer to the end surfaces of the vertical plates 2 and the horizontal plates 1 forming the rectangular structure.

[0055] Since the horizontal plate 1 and the vertical plate 2 are connected by the hinge 3, the hinge will make the sealing effect of the interior of the box poor, causing the heating device to consume more energy during high temperature environment testing. In addition, the hinge makes the box module unstable when unfolding.

[0056] Therefore, this embodiment also includes a module connector 4 to address these issues. The module connector 4 comprises an L-shaped steel section and a sealing rubber layer covering the outer surface of the steel section. Ribs are provided at the leading end of the steel section, and rib grooves are provided at the trailing end to facilitate the connection of the steel sections of two adjacent box modules. The sealing rubber layer is made of a high-temperature resistant rubber material.

[0057] Each box module is equipped with four module connectors 4. During installation, the module connectors 4 are placed at the four inner corners of the rectangular box module, with the outer walls of the module connectors 4 abutting against the inner walls of the box module. Because the module connectors 4 include a sealing rubber layer on the outer surface, the sealing rubber layer insulates the hinges.

[0058] It is worth mentioning that when the module connector 4 is installed on the box module, the front end of the module connector 4 exceeds the insertion opening at the front end of the box module and extends into the next box module.

[0059] Bolt holes are provided on both the front and rear ends of the horizontal and vertical surfaces of the L-shaped module connector 4 , and a plurality of bolt holes matching the bolt holes on the module connector 4 are provided on the box module.

[0060] The bolt holes on the box module can be defined as bolt holes A5 for matching the bolt hole positions of the module connector 4 corresponding to the box module and bolt holes B6 for matching the module connector 4 positions corresponding to the adjacent box module according to the connection relationship.

[0061] That is, a module connector 4 is connected to the bolt hole A5 on the corresponding box module through bolts, and the front end of the module connector 4 extends into the next box module and is connected to the corresponding bolt hole B6 on the next box module through bolts.

[0062] The box body is formed by connecting several box body modules end to end, and the box body and the box door 7 are installed to form the test box.

[0063] Furthermore, the door 7 includes a door frame and a door body that is movable relative to the door frame, allowing the entire structure to be opened. The door frame is a rectangular frame, one end of which is connected to the box body, and the other end of which is slidably connected to the top and bottom of the door 7 through a sliding groove structure provided at the top and bottom, allowing the door 7 to slide open.

[0064] When the door 7 is closed, rubber strips are provided between the left and right sides of the door 7 and the rectangular frame to ensure airtightness. The sliding opening method of the door 7 is the same as the structure of the door 7 of the container, which is the existing technology and will not be described in detail in this embodiment.

[0065] Specifically, the width of the rectangular frame of the door 7 is very narrow, so although it is a rectangular structure, it does not occupy a large area. When storing, it can be placed horizontally.

[0066] Furthermore, since the rectangular frame of the box door 7 is narrow, in order to meet the connection needs of the box door 7, a box door 7 connector is also included. The structure of the box door 7 connector is basically the same as that of the module connector 4, that is, it includes an L-shaped steel and a sealing rubber layer located on the outer wall of the steel.

[0067] However, the length of the door 7 connector is shorter than the length of the module connector 4 .

[0068] That is, several box modules are assembled end to end and fixed with module connectors 4 connected end to end. Except for the first and last two box modules, the other box modules are connected with the module connectors 4 corresponding to the box module and the module connectors 4 corresponding to the previous adjacent box with bolts.

[0069] As the first box module constituting the box door 7, it is only connected to the module connector 4 corresponding to the box module by bolts and to the connector of the box door 7 by bolts. As the last box module constituting the box door 7, it is only connected to the module connector 4 corresponding to the previous box module by bolts and to the connector of the box door 7 by bolts.

[0070] Furthermore, since the module connector 4 has ribs at its head end and rib grooves at its tail end, one end of one door connector 7 has ribs, and one end of another door connector 7 has rib grooves, for respectively plugging with the module connector 4 .

[0071] The assembly method of the modular irradiation environment test chamber described in this embodiment includes the following steps:

[0072] Step S1: Determine the size of the device to be tested and calculate the number of cabinet modules required based on the size;

[0073] Step S2: unfold the first box module of the box into a rectangular shape and stand it upright, and splice one end surface of the first box module with the box door 7;

[0074] Step S3: placing the door 7 connector at the inner corner of the box module, with the end of the door 7 connector extending out of the box module and into the door 7, and also located at the inner corner of the door 7;

[0075] Step S4: Connect the box module, the box door 7 and the box connector with bolts;

[0076] Step S5: unfold the adjacent next box module into a rectangular shape and stand it upright, and splice one end surface of the next box module with the other end of the first box module;

[0077] Step S6: Place the module connector 4 at the inner corner of the box module, with the end of the module connector 4 extending out of the box module and into the upper box module, and also located at the inner corner of the box, and the module connector 4 is plugged into the adjacent box door 7 connector;

[0078] Step S7: Bolt two adjacent box modules to the module connector 4;

[0079] Step S8: Continue to unfold the next adjacent box module into a rectangular shape and stand it upright, and splice one end surface of the box module with the other end of the previous box module;

[0080] Step S9: Place the module connector 4 at the inner corner of the box module, with the end of the module connector 4 extending out of the box module and into the upper box module, and also located at the inner corner of the box, and the module connector 4 is plugged into the adjacent module connector 4;

[0081] Step S10: Bolt two adjacent box modules to the module connector 4;

[0082] Step S11: Repeat steps S8 to S10 until the cabinet is assembled.

[0083] Step S12: splicing the box door 7 to the other end face of the rear box module of the box;

[0084] Step S13: Place the door 7 connector at the inner corner of the rear box module, with the end of the door 7 connector extending out of the rear box module and into the door 7, and also located at the inner corner of the door 7, and plug the door 7 connector into the adjacent module connector 4;

[0085] Step S14: Connect the box door 7, the box module and the module connector 4 with bolts.

[0086] By using the method described in this embodiment, the environmental test chamber can be conveniently disassembled and assembled, and the box modules constituting the environmental test chamber are foldable for easy storage, so that the environmental test chamber is easy to store when it is idle. When in use, it is assembled according to the size of the test equipment to be irradiated.

[0087] Example 2

[0088] The difference between this embodiment and the first embodiment is that the modular irradiation environment test chamber further includes a mover, which is used to be installed at the bottom of the test chamber to facilitate the movement of the test chamber on the ground and on the track of the irradiation system.

[0089] There are two movers, which are respectively installed at the bottom of the door 7. In addition, the movers can also be respectively installed at the bottom of the box body two ends.

[0090] like Figure 3 As shown, the mover includes a movable frame 8, which is bolted to the test chamber. A telescopic shaft is rotatably connected to the movable frame 8 via a hanger 19. The telescopic shaft comprises an inner telescopic shaft 10 and an outer telescopic shaft 11. The outer telescopic shaft 11 is sleeved at both ends of the inner telescopic shaft 10 and can move linearly along the inner telescopic shaft 10, thereby achieving telescopic movement of both ends of the telescopic shaft.

[0091] The movable frame 8 is rotatably connected to the telescopic inner shaft 10 via a hanger 19, providing support for the telescopic inner shaft 10. A limiting groove is provided on the inner wall of the telescopic outer shaft 11, and a limiting slider is provided on the outer wall of the telescopic inner shaft 10. The limiting slider is positioned within the limiting groove to limit rotation. This allows the telescopic outer shaft 11 to move only linearly relative to the telescopic inner shaft 10, preventing relative rotation.

[0092] The ends of the two telescopic outer shafts 11 are connected to pulleys 9 through pulley 9 mounting brackets. The pulley 9 mounting brackets can rotate with the telescopic shaft so that the pulley 9 mounting brackets are located in the vertical direction or the horizontal direction, thereby controlling the pulley 9 to be grounded or not grounded. Figure 5 and Figure 6 shown.

[0093] When the pulley 9 is grounded, it can slide on the ground or track, thereby driving the movement of the entire test box. When the pulley 9 is not grounded, the pulley 9 is located on one side of the mobile frame 8, and the mobile frame 8 contacts the ground, making it difficult to move and easy to keep the position fixed.

[0094] Furthermore, the telescopic inner shaft 10 is provided with a driven gear 115, which rotates with the driven gear 115. The driven gear 115 is connected to a driving gear 116 via a chain. The driving gear 116 is mounted on a drive shaft 122 and rotates with the drive shaft 122. Controlling the rotation of the drive shaft 122 controls the rotation of the driving gear 116, which in turn drives the driven gear 115, which in turn drives the telescopic inner shaft 10 (i.e., the telescopic shaft), thereby changing the position of the pulley 9.

[0095] Furthermore, in this embodiment, if Figure 7 As shown, the telescopic shaft used to connect the pulley 9 mounting frame is telescopic, and both ends of the telescopic shaft are telescopic, which means that it can drive the distance between the two pulleys 9 to change. The design purpose of this structure is to make the distance between the pulleys 9 variable to match the track spacing of different radiation source systems.

[0096] Furthermore, a connecting block 12 is sleeved on each of the two telescopic outer shafts 11, and a nut 13 is connected to one side of the connecting block 12. The two nuts 13 are respectively sleeved on a screw rod 14, and the thread teeth of the two nuts 13 are in opposite directions, so that when the screw rod 14 rotates forward or reverse, the two nuts 13 move toward or away from each other, thereby driving the telescopic outer shaft 11 to move, thereby adjusting the position of the pulley 9.

[0097] At one end of screw 14 is a non-threaded cylindrical section, mounted with a driven gear II17. Screw 14 rotates in unison with this gear. Driven gear II17 engages with a driving gear II18, which is sleeved on a drive shaft II23. This transmits the rotation of drive shaft II23 to screw 14, driving it in turn.

[0098] like Figure 4 As shown, the above-mentioned drive shaft I22 and drive shaft II23 are both connected to a rotating handle to operate and control the rotation of the drive shaft II23 and drive shaft II23. The rotating handle can be manually controlled or connected to a motor to control its rotation.

[0099] The rotating handle includes a rotating end 21, an optical axis 20, and a limiting end 24; the rotating end 21 and the limiting end 24 are respectively located at the two ends of the optical axis 20. A channel for the optical axis 20 is provided on the drive shaft II23 for the optical axis 20 to pass through, so that the rotating end 21 and the limiting end 24 are also respectively located at the two ends of the drive shaft II23. The limiting end 24 is also located between the drive shaft II23 and the drive shaft I22. The length of the optical axis 20 is greater than the length of the drive shaft II23. The drive shaft I22 and the side of the drive shaft II facing the limiting end 24 are both provided with limiting grooves, and the optical axis 20 can be moved so that the limiting end 24 is located in any limiting groove. The limiting end 24 and the limiting groove are both square structures. When the limiting end 24 is located in the limiting groove of the drive shaft I22, the rotating handle controls the drive shaft I22; when the limiting end 24 is located in the limiting groove of the drive shaft II23, the rotating handle controls the drive shaft II23.

[0100] Furthermore, in this embodiment, if Figure 7 As shown, a mounting groove 25 is provided at the bottom of the door 7, and the movable frame 8 is embedded in the mounting groove 25. The bottom of the movable frame 8 is flush with the bottom of the door 7. The side of the movable frame 8 is flush with the side of the door 7 to ensure that when the pulley 9 is located on the side of the movable frame 8 (i.e., on the side of the door 7), the bottom of the door 7 is in contact with the ground.

[0101] During the assembly of the test box, the movable frame 8 is first connected to the box door 7 .

[0102] It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial improvements are made on the present invention, they also fall within the protection scope of the present invention.
