Figure 6 A perspective view of the fifth state of the detection device according to an embodiment of the present disclosure is schematically shown, in which the main housing is not shown.

[0049] As Figures 1-6 shown, the detection device may include a main housing 1, a handling mechanism 2, a collection mechanism 3, and a detection device 4. The handling mechanism 2, the collection mechanism 3, and the detection device 4 may be respectively disposed inside the main housing 1. The collection mechanism 3 may communicate with the dangerous space, that is, a part of the structure of the collection mechanism 3 may extend from inside the main housing 1 to the outside of the main housing 1 into the dangerous space, so that the air in the dangerous space can enter the collection mechanism 3.

[0050] Further, in response to the handling mechanism 2 placing the adsorption block 6 on the collection mechanism 3, the collection mechanism 3 extracts the air in the hazardous space and causes the air to flow through the adsorption block 6, so that the adsorption block 6 can adsorb the radioactive substances in the air. Among them, the adsorption block 6 can be a device with the function of adsorbing radioactive substances. For example, when the radioactive substance is radioactive iodine, the adsorption block 6 can be an iodine box. When the radioactive substances are transuranic elements such as plutonium and americium, the adsorption block 6 can be a transuranic element sampling box.

[0051] Figure 7 Schematically shows a partial cross-sectional view of the detection device according to an embodiment of the present disclosure.

[0052] Further, in response to the handling mechanism 2 placing the adsorption block 6 that has adsorbed radioactive substances in the collection mechanism 3 on the detection device 4, the detection device 4 can detect the radioactive substances in the adsorption block 6. As Figure 7 shown, a detector 41 can be provided in the detection device 4 to detect the content of the radioactive substances in the adsorption block 6, so as to determine the concentration of the radioactive substances in the air. For example, when the radioactive substance is radioactive iodine, the detector 41 can be a sodium iodide detector 41.

[0053] According to the embodiment of the present disclosure, by providing the handling mechanism 2, the adsorption block 6 can be placed on the collection mechanism 3 or the detection device 4. By providing the collection mechanism 3, the air in the hazardous space can be introduced into the detection device, so that the adsorption block 6 adsorbs the radioactive substances in the air. After the adsorption block 6 adsorbs the radioactive substances, the detection device 4 can be used to detect the content of the radioactive substances in the adsorption block 6, so as to determine the concentration of the radioactive substances in the air. The detection device can realize the automatic collection and detection of the radioactive substances in the air, that is, it can directly detect the radioactive substances in the air in the hazardous space with radioactive substances, so as to improve the detection accuracy and eliminate the need for manual on-site sampling, which can improve the detection safety.

[0054] In some embodiments, the detection device may further include a recovery box. After the adsorption block 6 is detected and exits the detection device 4, the following clamping device 21 can place the adsorption block 6 in the recovery box.

[0055] Figure 8 Schematically shows a perspective view of the storage device according to an embodiment of the present disclosure.

[0056] As Figures 2-6 and Figure 8As shown, in some embodiments, the detection device may further include a storage device 5. The storage device 5 may be disposed within the main housing 1. The storage device 5 is formed with a first accommodation space 51 for accommodating a plurality of adsorption blocks 6. The storage device 5 has a sealed state and an open state. When the storage device 5 is in the open state, the handling mechanism 2 can pick up the adsorption blocks 6 from the storage device 5. When the storage device 5 is in the sealed state, the adsorption blocks 6 can be protected from the external environment.

[0057] In some embodiments, the detection device may further include a control device (not shown in the figure). The control device may be communicatively connected to the handling mechanism 2, the acquisition mechanism 3, the detection device 4, the storage device 5, and an external host computer respectively. The staff can use the host computer to send control instructions to the control device, and the control device can control the handling mechanism 2, the acquisition mechanism 3, the detection device 4, and the storage device 5 to work based on the control instructions, thereby facilitating the staff to control the detection device outside the dangerous space with radioactive substances.

[0058] In some embodiments, the detection device may further include a display screen panel. The staff can input the control instructions into the control device in advance by operating the display screen panel and read the detection data after the detection is completed.

[0059] In some embodiments, the detection device may further include a power device (not shown in the figure). The staff can use the host computer to control the power device to move the detection device from outside the dangerous space into the dangerous space. The power device may be similar to the power device used to drive an automated guided vehicle to move.

[0060] As Figures 2-6 and Figure 8 shown, in some embodiments, the storage device 5 may include a cover body 52, a first carrier 53, a first driving part 54, and a bottom plate 510. The bottom plate 510 is formed with a groove 511 that matches the shape of the cover body 52, that is, the cover body 52 can be buckled with the bottom plate 510. The first carrier 53 is disposed on the bottom plate 510. A plurality of adsorption blocks 6 are disposed on the first carrier 53. The first carrier 53 and the cover body 52 can form the first accommodation space 51. The first driving part 54 may be connected to the cover body 52. The first driving part 54 can drive the cover body 52 away from or close to the bottom plate to make the storage device 5 in the open state or the sealed state. The first driving part 54 may include a first motor 58 and a first transmission assembly 59. The first motor 58 can drive the cover body 52 to move by driving the first transmission assembly 59 to move. The first transmission assembly 59 can drive the cover body 52 to move based on a working principle similar to that of a linkage mechanism, a screw drive, or an electric push rod.

[0061] As Figures 2-6 and Figure 8As shown, in some embodiments, a plurality of adsorption blocks 6 may be uniformly arranged along the circumference of the first carrier 53. As Figure 8 shown, the first carrier 53 may be configured as a circle. A plurality of adsorption blocks 6 may be evenly spaced on the edge of the first carrier 53.

[0062] As Figure 8 shown, further, the storage device 5 may further include a second driving part 57. The second driving part 57 may be connected to the first carrier 53. The second driving part 57 may be located on a side of the first carrier 53 away from the cover 52. The second driving part 57 may be used to drive the first carrier 53 to rotate along the axial direction of the first carrier 53, that is, the second driving part 57 may drive the first carrier 53 to rotate itself. By controlling the rotation of the first carrier 53, the plurality of adsorption blocks 6 can be sequentially rotated to a predetermined position, so that the handling mechanism 2 can sequentially pick up the adsorption blocks 6. For example, in the case where there are 6 adsorption blocks 6, the rotation angle of the first carrier 53 can be controlled to be 60° each time, so that the latter adsorption block 6 can be rotated to the position of the former adsorption block 6. By providing a plurality of adsorption blocks 6, the working time of the detection device can be extended, and thus the detection accuracy can be further improved.

[0063] As Figure 8 shown, in some embodiments, the storage device 5 may further include a first mounting bracket 55. The first driving part 54 may be mounted on the first mounting bracket 55 and pass through the first mounting bracket 55 to be connected to the cover 52. The storage device 5 may further include a plurality of limiting rods 56. Each limiting rod 56 may be mounted on the first mounting bracket 55. The cover 52 may be sleeved on the plurality of limiting rods 56 respectively and can slide along the limiting rods 56. The limiting rods 56 may limit the moving direction of the cover 52 to prevent the cover 52 from tilting during movement, thereby improving the sealing performance of the storage device 5.

[0064] Figure 9 Schematically shows a perspective view of the pressing device according to an embodiment of the present disclosure. Figure 10 Schematically shows a perspective view of another angle of the pressing device according to an embodiment of the present disclosure. Figure 11 Schematically shows a cross-sectional view of the pressing device according to an embodiment of the present disclosure.

[0065] As Figures 1-6 and Figures 9-11 shown, in some embodiments, the acquisition mechanism 3 may include an intake pipe 31, a pressing device 32 and an intake chamber 7. The first end of the intake pipe 31 (such as Figure 2The upper end of the intake duct 31 shown) can extend from inside the main housing 1 to outside the main housing 1 into the hazardous space to communicate with the hazardous space. The intake duct 31 can be configured as a hollow tubular structure to allow air to flow. The air outside the detection device, that is, the air inside the hazardous space, can enter the detection device through the intake duct 31. The pressing device 32 is formed with a second accommodation space 33 for accommodating the adsorption block 6. The handling mechanism 2 can place the adsorption block 6 in the second accommodation space 33. The first end of the pressing device 32 (such as Figure 2 the upper end of the pressing device 32 shown) is formed with a first through hole 34 communicating with the second end of the intake duct 31 (such as Figure 2 the lower end of the intake duct 31 shown), that is, air can enter the first through hole 34 from the intake duct 31. The second end of the pressing device 32 (such as Figure 2 the lower end of the pressing device 32 shown) is formed with a second through hole 35.

[0066] Further, a filter screen can be provided at the first end of the intake duct 31 to prevent impurities in the air from entering the device, thereby further improving the detection accuracy.

[0067] Further, the pressing device 32 has a pressing state and a relaxed state. When the pressing device 32 is in the relaxed state, the pressing device 32 releases the adsorption block 6 so that the handling mechanism 2 can place the adsorption block 6 in the second accommodation space 33. When the pressing device 32 is in the pressing state, the pressing device 32 presses the adsorption block 6, and the adsorption block 6 completely covers the first through hole 34 and the second through hole 35, so that air can flow from the first through hole 34 through the adsorption block 6 and then into the second through hole 35. By setting the adsorption block 6 to completely cover the first through hole 34 and the second through hole 35, it is possible to prevent air from flowing out through the gaps between the adsorption block 6 and the first through hole 34 and the second through hole 35, thereby further improving the detection safety. Further, the effective adsorption surface of the adsorption block 6 can be substantially the same as the cross-sectional shapes of the first through hole 34 and the second through hole 35, that is, the effective adsorption surface of the adsorption block 6 matches the cross-sectional shapes of the first through hole 34 and the second through hole 35, so as to prevent air from leaking from the parts of the adsorption block 6 that are not covered by the first through hole 34 and the second through hole 35.

[0068] Figure 12 Schematically shows a perspective view of the air suction part of the embodiment of the present disclosure. Figure 13 Schematically shows a cross-sectional view of the air suction part of the embodiment of the present disclosure. Figure 14 Schematically shows the positional relationship between the pressing device, the air suction part and the exhaust duct of the embodiment of the present disclosure.

[0069] Further, as Figures 11-14As shown, the intake chamber 7 can communicate with the second through-hole 35. A suction part 71 is provided in the intake chamber 7. In response to the pressing device 32 pressing the adsorption block 6, the suction part 71 sucks the air in the dangerous space to flow through the adsorption block 6. The suction part 71 can include a suction motor 72 and blades 73. The suction motor 72 can be used to drive the blades 73 to rotate to suck air into the intake chamber 7. A fan (not shown in the figure) can also be provided in the intake chamber 7. The fan can be arranged at the bottom of the intake chamber 7 to dissipate heat from the suction motor 72.

[0070] As Figure 4 , Figure 11 and Figure 14 As shown, in some embodiments, the intake chamber 7 further includes an exhaust duct 8. The air sucked into the intake chamber 7 can be discharged through the exhaust duct 8. The exhaust duct 8 can communicate with the dangerous space, and the air in the intake chamber 7 can be discharged to the dangerous space through the exhaust duct 8. Specifically, the air in the dangerous space enters the pressing device 32 through the intake duct 31, enters the adsorption block 6 through the first through-hole 34 of the pressing device 32. The adsorption block 6 can adsorb the aerosol particles in the air. The air after being adsorbed by the adsorption block 6 enters the intake chamber 7 through the second through-hole 35 of the pressing device 32, and then is discharged to the dangerous space through the exhaust duct 8.

[0071] As Figure 4 , Figures 9-14 As shown, in some embodiments, the pressing device 32 can include a first part 36, a second part 37 and a third driving part 38. The first part 36 communicates with the second end of the intake duct 31. The second part 37 communicates with the intake chamber 7. The adsorption block 6 is arranged in the second part 37. The third driving part 38 is connected to the first part 36. The third driving part 38 can drive the first part 36 to approach or move away from the adsorption block 6 to press or relax the adsorption block 6. The air can enter through the intake duct 31, pass through the first part 36 to the adsorption block 6, and the air after being adsorbed by the adsorption block 6 passes through the first part 36 and enters the intake chamber 7.

[0072] As Figure 4 , Figures 9-14As shown, in some embodiments, the first part 36 includes a connecting portion 39, a first elastic member 310, and a pressing block 311. The connecting portion 39 is connected to the third driving portion 38, and the third driving portion 38 can drive the connecting portion 39 away from or close to the second part 37. The pressing block 311 is connected to the connecting portion 39 through the first elastic member 310 and matches the shape of the upper surface edge of the adsorption block 6. The third driving portion 38 may include a second motor 317 and a second transmission assembly 318. The second motor 317 can drive the connecting portion 39 to move by driving the second transmission assembly 318 to move. The second transmission assembly 318 can drive the connecting portion 39 to move through a working principle similar to that of a link mechanism, a screw drive, or an electric push rod. The second transmission assembly 318 can be connected to the connecting portion 39 through a connecting member 312.

[0073] Further, when the third driving portion 38 drives the pressing block 311 to press the adsorption block 6, under the reaction force of the adsorption block 6, the pressing block 311 moves in a direction away from the adsorption block 6 based on the elasticity of the first elastic member 310, so that a clamping force can be more accurately applied to the adsorption block 6 and the adsorption block 6 can be prevented from being damaged. Specifically, the deformation amount X3 of the first elastic member 310 can be obtained according to the initial distance X1 between the first part 36 and the adsorption block 6 and the form distance X1 of the third driving portion 38 driving the connecting portion 39 to move. According to the deformation amount X3 of the first elastic member 310 and the stiffness coefficient K of the first elastic member 310, the elastic force F can be obtained, that is, the elastic force F can represent the acting force applied by the first part 36 to the adsorption block 6. Thus, by setting the pressing block 311 to be connected to the connecting portion 39 through the first elastic member 310 and the third driving portion 38 to be connected to the connecting portion 39, a clamping force can be more accurately applied to the adsorption block 6.

[0074] As Figure 6 and Figure 9 As shown, in some embodiments, the pressing device 32 further includes a second mounting bracket 313, a plurality of struts 314, and a plurality of second elastic members 315. The plurality of struts 314 can be respectively mounted on the second mounting bracket 313. The first part 36 and the second part 37 are respectively slidably sleeved on the plurality of struts 314. The connecting portion 39 can pass through the second mounting bracket 313 and be connected to the intake pipe 31. The pressing device 32 further includes a third mounting bracket 316. The third driving portion 38 can be mounted on the third mounting bracket 316.

When the third driving part 38 drives the first part 36 to press the adsorption block 6, the first part 36 and the second part 37 move in the direction close to the air inlet chamber 7 based on the elasticity of the second elastic part 315, so as to play a role in buffering and shock absorption. When the third driving part 38 drives the first part 36 away from the adsorption block 6, the second part 37 moves in the direction away from the air inlet chamber 7 based on the elasticity of the second elastic part 315 to restore the initial state.

The fourth driving part 23 is configured to drive the robotic arm 24 to move in the vertical direction. The fourth driving part 23 can drive the robotic arm 24 to move in the vertical direction by a working principle similar to that of a link mechanism, a screw drive or an electric push rod. The gripper 25 is rotatably connected to the second end of the robotic arm 24 (such as Figure 4 the left end of the robotic arm 24 shown). The robotic arm 24 may include a plurality of sequentially rotatably connected arms. The arm at the first end is connected to the fourth driving part 23, and the arm at the end is connected to the gripper 25, so as to increase the movement range of the gripper 25. Driven by the robotic arm 24 and the fourth driving part 23, the gripper 25 moves to the collection mechanism 3, the storage device 5 or the conveying device 22. The gripper 25 can have a clamping state for clamping the adsorption block 6 and a releasing state for releasing the adsorption block 6, so as to clamp and place the adsorption block 6 from the storage device 5 to the pressing device 32 or clamp and place the adsorption block 6 from the pressing device 32 to the conveying device 22.

[0078] In some embodiments, the conveying device 22 may include a slide rail 26, a second carrier 27 and a fifth driving part 28.

The second carrier 27 can be connected to the fifth driving part 28 and is slidably arranged on the slide rail 26. The fifth driving part 28 can drive the second carrier 27 to move horizontally on the slide rail 26 so that the adsorption block 6 enters or exits the detection device 4.

[0079] In some embodiments, the detection device may further include a plurality of sensors. The plurality of sensors are respectively disposed close to the storage device 5, the collection mechanism 3, and / or the conveying device 22 to detect whether the adsorption block 6 is located at the storage device 5, the collection mechanism 3, and / or the conveying device 22. The sensors may be laser sensors. Further, the sensors may be respectively disposed close to the first carrier 53, the second carrier 27, and the second portion 37. Further, sensors may also be disposed on the gripper 25 to detect whether the gripper 25 moves to the adsorption block 6 and whether it holds the adsorption block 6 in a clamped manner.
