Description

Technical Field

[0001] The present application relates to a scintillator detector, belonging to the technical field of radioactive detection equipment. Background Art

[0002] Plastic scintillator detectors are commonly used in radioactivity measurement. Currently, plastic scintillator detectors used for radiation detection in the domestic market primarily consist of a plastic scintillator, a photomultiplier tube, and a front panel. Their principle is that when radiation enters the plastic scintillator, the atoms or molecules in the scintillator are excited and produce fluorescence. The photomultiplier tube amplifies this fluorescence and converts it into an electrical signal, which is then sent to the front panel for processing.

[0003] Patent publication number CN114488260A discloses a plastic scintillator detector device, in which a square plate is driven out of a positioning groove by pulling a pull plate, and then a sliding ring is pushed upward, and multiple bending plates are driven to move toward a side away from the detector housing through multiple connecting plates, so that the multiple bending plates are disconnected from the corresponding snap-in grooves, thereby releasing the fixation of the bottom cover, so that the bottom cover can be moved downward to be disassembled, and the plastic scintillator, photomultiplier tube, tube holder and front circuit board arranged therein can be disassembled.

[0004] However, the above-mentioned scintillator detector device still has certain shortcomings. The detector needs to be disassembled by pulling the pull plate, pushing the sliding ring, and then driving the bent plate to move through a series of transmission structures. Its structural transmission is relatively unstable, and the whole is exposed to the outside. If it is not careful, it will be damaged, resulting in obstruction of disassembly. During installation, it is necessary to ensure that multiple bent plates are accurately inserted into the card slots to complete the installation. Once a bent plate cannot be smoothly inserted into the card slot, the installation will be obstructed, and the installation is more inconvenient. Summary of the Invention
