[0002] During the production process of sealed radioactive sources, in accordance with the requirements of national standard GB15849, it is necessary to take samples and inspect the radioactive contamination on the surface of the radioactive source cladding.
[0003] At present, there are two methods for taking samples and inspecting the radioactive contamination on the surface of the sealed radioactive source cladding in China: one is to use a manipulator to clamp a piece of absorbent cotton to manually wipe and sample the surface of the cladding. This method has the defects of insufficient, uneven, and unstable wiping, and there is also a possibility of cross - contamination of the wiping samples, thus affecting the accuracy and reliability of the surface contamination wiping inspection results; the other is to use the decontamination solution immersion method to sample and measure the contaminated liquid removed from the surface of the cladding. The disadvantage of this method is that the operation is cumbersome and it generates radioactive waste liquid that is difficult to handle. Content of the Utility Model

Specific embodiments
[0019] To enable those skilled in the art to more clearly understand the technical solution of the present application, the present utility model will be further described below with reference to the accompanying drawings.
[0020] As Figures 1-3 shown in the embodiment, an outer pipe wiping device includes a workbench 10, a mounting assembly 20 and a driving assembly 30 are arranged on the workbench 10, the driving assembly 30 is arranged on one side of the mounting assembly 20, the mounting assembly 20 includes at least two groups of lifting groups 21 arranged at intervals, the lifting group 21 includes a lifting seat 211 and a lifting pressing table 212, the lifting seat 211 and the lifting pressing table 212 are respectively assembled with a first cylinder 213 and a second cylinder 214, and the first cylinder 213 and the second cylinder 214 are synchronously driven in opposite directions to tightly fix the outer pipe 50 placed on the lifting seat 211; the driving assembly 30 includes a slide rail 31, a slider 32 arranged on the slide rail 31 and a motor 33 arranged at one end of the slide rail 31, a lead screw cooperated with the motor 33 is connected to the slider 32, a placing rack 34 for placing the wiping part 40 is arranged on the slider 32, and the motor 33 drives the slider 32 to linearly move along the slide rail 31 to drive the wiping part 40 to wipe the outer pipe 50 comprehensively.
[0021] Specifically, a plurality of mounting grooves 11 are arranged on the workbench 10, the mounting grooves 11 are arranged in one-to-one correspondence with the lifting groups 21, and the lifting groups 21 are fixed in the mounting grooves 11 through fixing plates 12. The lifting group 21 includes a lifting table 215, the lifting table 215 is fixedly cooperated with the workbench 10 through a fixing plate 12, the lifting seat 211 and the lifting pressing table 212 are arranged on the upper end surface of the lifting table 215, and the first cylinder 213 and the second cylinder 214 are arranged on the lower end surface of the lifting table 215; a distance sensor is arranged on the lifting seat 211, and the first cylinder 213 and the second cylinder 214 are synchronously started when the wiping part 40 approaches.
[0022] It can be understood that the lifting groups 21 are arranged at intervals, which can ensure that only one lifting group starts each time, and the other lifting groups 21 continue to clamp the outer pipe 40. That is, only the lifting group 21 close to the wiping member 40 will start the first cylinder 213 and the second cylinder 214 to release the outer pipe 50. After wiping, the first cylinder 213 and the second cylinder 214 are restored so that the lifting seat 211 and the lifting pressure table 212 return to the state of clamping the outer pipe 40.
[0023] In this embodiment, an arc-shaped groove 35 is provided on the placing rack 34, and the wiping member 40 is an annular member, which is clamped in the arc-shaped groove 35. A through hole is provided in the middle of the wiping member 40 for the outer pipe 50 to pass through movably. The inner wall of the wiping member 40 in contact with the outer pipe 50 is provided with flexible wiping cotton, which has good wrapping property and can wipe the outer wall of the entire outer pipe.
[0024] Continuing to refer to the drawings, it can be seen that the installation assembly 20 further includes a bracket 22, which is arranged on the side away from the motor 33, and the bracket 22 is on the same horizontal line as the lifting group 21; a pin shaft 23 is provided on the bracket 22 and abuts against one end of the outer pipe 50. That is, a pin shaft is provided on the bracket 22 to abut against one end of the outer pipe, the other end of the outer pipe is suspended on the workbench, and the length of the slide rail 31 is greater than the length of the outer pipe 50, and both ends of the slide rail 31 are placed outside the outer pipe 50, which further ensures that the wiping member can wipe the entire outer pipe from beginning to end.
[0025] In this embodiment, a first accommodation groove group 13 and a second accommodation groove group 14 are also provided on the workbench 10 in cooperation. The first accommodation groove group 13 and the second accommodation groove group 14 are oppositely arranged at both ends of the upper end surface of the workbench 10, and are respectively arranged near the end and the tail of the outer pipe 50. The first accommodation groove group 13 is used to place the wiping member 40 to be used; the second accommodation groove group 14 is used to place the used wiping member 40. Subsequently, the wiping member 40 is detected, which can not only clarify whether the outer wall of the outer pipe is clean, but also avoid environmental pollution.
[0026] In a preferred embodiment, the installation component 20 includes two sets of lifting groups 21. The two sets of lifting groups 21 are arranged at intervals from the bracket 22. One end of the outer pipe 50 near the motor 33 is suspended, and the other end abuts against the pin shaft 23 on the bracket 22. The wiping member 40 wipes the outer pipe 50 from the side close to the motor 33. During specific use: Place the outer pipe 50 on the lifting seats 211 of the two sets of lifting groups 21, and drive the second cylinder 214 to make the lifting and pressing platform 212 press the outer pipe 50 tightly; Place the wiping member 40 in the arc groove 35 of the placement rack 34. When the motor 33 drives the slider 32 to drive the wiping member 40 past the first set of lifting groups 21, the first cylinder 213 and the second cylinder 214 of the first set of lifting groups 21 are started synchronously, so that the outer pipe 50 at this place is in a suspended state. After the wiping member 40 wipes the outer pipe 50 at this place, the first cylinder 213 and the second cylinder 214 synchronously drive the lifting seat 211 and the lifting and pressing platform 212 to cooperate to clamp the outer pipe 50; Then the wiping member 40 passes the second set of lifting groups 21, and the first cylinder 213 and the second cylinder 214 of the second set of lifting groups 21 are started synchronously, so that the outer pipe 50 at this place is in a suspended state. After the wiping member 40 wipes the outer pipe 50 at this place, the first cylinder 213 and the second cylinder 214 synchronously drive the lifting seat 211 and the lifting and pressing platform 212 to cooperate to clamp the outer pipe 50; Finally, when the wiping member 40 wipes the entire outer pipe 50 clean and enters the pin shaft 23, take out the wiping member 50 and place it in the second accommodation groove group 14 for subsequent inspection.
[0027] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
