Detailed Description
As shown in fig. 1 to 4, the radioactive substance shielding container device of the present example is that the shielding container 2 is a shell with a lead filling layer 23 filled in the middle part, which is formed by a base 21, an outer wall 22 and an inner wall 24 which are fixedly connected in a sealing way, wherein the lower part of the inner wall 24 forms a cylindrical cavity, the upper part forms an elliptical cavity 24-1, and the clamp is convenient for placing and taking out the sampling bottle B. The top opening of the shielding container 2 is covered with a shielding cover 1 with a lower surface in the middle of which an elliptical cavity 24-1 can be embedded. During sampling, the shielding container 2 is placed on a transport trolley, which is fixedly provided with two parallel guide rails 4. The guide rail 4 is formed with upper and lower horizontal guide grooves 4-1 for guiding the rollers 13, respectively, and the upper horizontal guide groove 4-1 is formed with a sinking positioning recess 4-2 adjacent to one end of the shielding container 2. The tail end of the horizontal guide groove is provided with a groove 4-4 which is pulled out in place and a limiting pin 4-3 which prevents the shielding cover 1 from falling off.
Four rollers 13 are respectively arranged on two side surfaces of the shielding cover 1, a hinge seat 11 and a tilting limiting block 12 are fixed at the rear end of the shielding cover 1, and a lever handle 3 positioned between two parallel guide rails 4 is hinged through the hinge seat 11. The lever handle 3 is composed of a vertical lever section 31 with a hinged middle point and a handle part 32 extending from the upper end of the vertical lever section 31, and the lower end of the vertical lever section 31 forms a prying flange 3-1 which can be abutted against the reinforcing block 25 on the outer side of the shielding container 2.
