Embodiment 1

[0040] The linear movement mechanism comprises a driving motor 202, a threaded leading screw 203 and a leading screw nut, the threaded leading screw 203 is arranged on the top of the mounting plate 201 in parallel, and the threaded leading screw 203 is rotatably connected with the mounting plate 201, and the torque output of the driving motor 202 end is coaxial with the threaded screw 203 and fixedly connected, the screw nut is set on the threaded screw 203, and the screw nut is slidably connected with the mounting plate 201, and the sample clamping assembly 4 is fixedly connected with the screw nut.

[0041] The ball screw structure is composed of the threaded screw 203 and the screw nut, and the rotary motion of the driving motor 202 is converted into the linear motion of the screw nut. This is a common structure at the present stage, and no further description is needed.

Embodiment 2

[0043]The linear moving mechanism includes a linear motor, the primary of the linear motor is fixedly connected to the upper side of the mounting plate 201 , and the sample holding assembly 4 is fixedly connected to the secondary of the linear motor.

[0044] In this embodiment, a linear motor is directly used, and the linear motion of the sample holding assembly 4 is controlled through the secondary motion of the linear motor. The linear motor is a common structure at the present stage, and it will be described further.

[0045] In addition, in order to realize further automation of a device for wiping and sampling the surface of nuclear waste barrels, a sensor 205 can be added and fixed on the linear moving assembly 2 to detect the position of the sample holding assembly 4 .

[0046] The number of sensors 205 is three, and the three sensors 205 are respectively installed on three sensor fixing seats 206, and the three sensor fixing seats 206 are fixedly connected with the mou...

Abstract

The invention discloses a nuclear waste barrel surface wiping and sampling device. The nuclear waste barrel surface wiping and sampling device comprises a vertical lifting assembly, a linear moving assembly and a sample clamping assembly; the shielding transfer chamber for wiping and sampling the surface of the nuclear waste barrel comprises the wiping and sampling device, the shielding transfer chamber comprises a plurality of metal shielding walls which are fixedly connected through anchor hooks, a door hole is formed in one metal shielding wall, and a door plate matched with the door hole is arranged in the door hole; according to the nuclear waste barrel surface wiping and sampling device, sampling of any position of a nuclear waste barrel is achieved by arranging the vertical lifting assembly, and long-distance sampling is achieved by arranging the linear moving assembly; by arranging the small shielding transfer chamber, personnel are shielded and protected in the sampling process and when samples are collected after sampling is completed, and the exposure dose of the personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of radioactive waste treatment, in particular to a nuclear waste barrel surface wiping sampling device and a shielding transfer chamber. Background technique [0002] After the radioactive nuclear waste is loaded into barrels, it is necessary to wipe and sample the loose and non-fixed pollutants on the surface of the nuclear waste barrels, then detect and record them, and decide whether to decontaminate the nuclear waste barrels before temporary storage and transfer according to the test results operate. At present, the existing surface wiping device cannot realize the wiping and sampling of any position of the drum body, and the personnel cannot be effectively isolated when the wiping is completed and the samples are collected, and the safety of the personnel cannot be guaranteed. Contents of the invention [0003] The problem to be solved by the present invention is that it is impossible to sample any p...
