Description

Technical Field

[0001] This utility model relates to the field of surface contamination measurement technology, and in particular to a measuring device for surface contamination measurement. Background Technology

[0002] With the continuous advancement of science and technology, semiconductor technology, electronic technology, and nuclear detection technology have developed rapidly. These technological advancements have provided strong technical support for the research and development of surface contamination measuring devices, resulting in continuously improved performance, smaller size, and better portability and stability of the devices, making them more adaptable to the measurement needs of different scenarios. In order to protect public health and environmental safety, governments around the world have formulated strict radiation protection regulations and standards. These regulations and standards have made clear provisions for the use, transportation, and storage of radioactive materials, as well as the control of radioactive contamination in workplaces, requiring regular monitoring of surfaces that may be subject to radioactive contamination to ensure that the emission of radioactive materials and the level of surface contamination meet national standards.

[0003] A search revealed Chinese Patent Publication No. CN221991515U, which discloses a convenient measuring device for surface contamination analyzers, relating to the field of nuclear monitoring instrument technology. The device includes a support frame with four casters mounted underneath, and a first and second groove formed on the outer wall of the support frame. A surface contamination analyzer body is placed in the middle of the first groove, and a limiting mechanism for self-positioning is provided on one side of the analyzer body. This convenient measuring device is suitable for large-area surface contamination testing on flat ground. After the support frame and analyzer body are installed, the support frame can be moved directly by pushing it with a handle, facilitating testing over large areas and saving time. Furthermore, the push mechanism allows the device to be folded and stored when not in use, minimizing space usage. However, this invention does not consider the inability to brake the device after movement, which could lead to displacement during testing, resulting in a different detection position and reduced accuracy.

[0030] Working principle: Pushing the push handle 15 causes the base plate 1 to move to the designated position under the action of the caster wheel 13.

The telescopic rod 8 will push the push plate 9 and the connecting plate 10 to move to the right together, thereby driving the triangular block 11 to move to the right. During the movement of the triangular block 11 to the right, it will press the sliding rod 12 below, causing the sliding rod 12 to move downward along the inner wall of the light-shielding frame 6 and push the L-shaped plate 4. The L-shaped plate 4 will rotate around the outer wall of the rotating column 3 and eventually rotate to a vertical state, so that the friction plate 24 contacts the ground and presses to generate friction, thus fixing the equipment in this position.

When the length of the sliding column 207 needs to be extended, rotate the limiting ring 206 so that the limiting ring 206 rotates out from the outer wall of the limiting column 205, and then pull the limiting column 205 out from the inner wall of the limiting hole 204. At this time, the sliding column 207 loses its limit. Then, start the telescopic rod 203. The telescopic rod 203 will push the sliding column 207 so that the sliding column 207 slides out from the inner wall of the hollow column 202. When the specified length is reached, stop the telescopic rod 203 and insert the limiting column 205. Then tighten the limiting ring 206 to fix the sliding column 207 in this position. This realizes the extension of the sliding column 207, so that the equipment can adapt to more different users, thereby improving the adaptability of the equipment.
