Description

Technical Field

[0001] This utility model relates to the field of radiation shielding technology for radioactive sources, and in particular to a radiation shielding device for radioactive sources. Background Technology

[0002] Radiation refers to the phenomenon where a portion of the electromagnetic energy emitted by a source escapes from the source and propagates to a distance without returning to the source. The energy diffuses outward in the form of electromagnetic waves or particles. Radiation itself is a neutral term, but the radiation from certain substances can be harmful, and some objects that emit radiation can be harmful to the human body. This necessitates protection against radiation sources, which requires a radiation shielding device. Radiation shielding refers to a radiation protection technology that uses the interaction between radiation and matter to reduce the radiation level in a certain area, thereby reducing the exposure of people and the radiation damage to materials. It is also a material protection measure.

[0003] To this end, Chinese patent application number CN221008617U discloses a nuclear radiation shielding device, belonging to the field of nuclear radiation protection equipment; it includes a boron-reinforced steel housing, a lead plate, a boron carbide aluminum plate, and a tungsten alloy tray; the lead plate is placed on the inner wall of the housing; the boron carbide aluminum plate is placed on one side of the lead plate; and the tungsten alloy tray is fixed in the middle of the housing. Beneficial effects: The lead plate in this application acts as a third barrier, shielding most gamma rays and blocking neutrons while absorbing slow neutrons; combined with the boron carbide aluminum plate, it can handle most neutrons and gamma rays. For neutrons emitted from nuclear materials, this application uses a tungsten alloy tray. Tungsten alloy itself has a melting point as high as 3400℃, possessing not only extremely strong gamma-ray shielding effects but also the ability to withstand the high temperatures generated by neutron activation.

[0004] Current radiation shielding devices for radioactive sources can basically meet people's needs, but some problems still exist, as detailed below:

[0005] 1. The problem of difficulty in fixing the protective shell of the radiation source shielding device is that the radiation object needs to be placed inside the protective shell during use. The protective shell may fall off during use, and the sealing between the protective plate and the connecting block is not strong enough.

[0006] 2. The problem of radiation shielding devices for radioactive sources having difficulty locating radioactive objects: radioactive objects inside the protective shell may shift, which may cause damage to the protective shell. Utility Model Content

[0007] The purpose of this invention is to provide a radiation shielding device for a radiation source, which solves the shortcomings of existing radiation shielding devices that are difficult to fix the protective shell and difficult to locate the radiation object.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a radiation shielding device for a radiation source, including legs;

[0009] The top of the support leg is equipped with a telescopic structure, the top of the telescopic structure is equipped with a base, and the top of the base is equipped with a connecting block.

[0010] A protrusion is installed on the inner side of the connecting block, and a protective shell is movably connected to the top of the connecting block. A handle is installed on the top of the protective shell.

[0011] Positioning structures are installed on both sides and both ends of the protective shell, an airbag is provided at the bottom of the protective shell, and a disassembly structure is installed at the bottom of the protective shell.

[0012] In use, the protective shell can be made of structural materials used to shield nuclear radiation from reactors, such as FePb, water, graphite, boron-containing materials, and concrete, which can effectively prevent radiation. The first and second telescopic rods form a sliding structure, and the second telescopic rod can slide inside the first telescopic rod. The sliding of the second telescopic rod can adjust the height of the support feet at the bottom, thus adjusting the height of the device and leveling it.

[0013] Furthermore, the outer diameter of the protective shell is smaller than the inner diameter of the connecting block, and the protective shell and the connecting block form a snap-fit ​​structure, which facilitates disassembly.

[0014] Furthermore, the positioning structure includes a threaded rod, a screw block, a positioning plate, and anti-slip texture. The threaded rod extends through both sides and ends of the protective shell. A screw block is installed on one side of the threaded rod, and a positioning plate is installed on the other side of the threaded rod. The positioning plate can be used to position and fix the radiating objects inside the protective shell.

[0015] Furthermore, one side of the positioning plate is provided with anti-slip texture, which is arranged at equal intervals on one side of the positioning plate. The anti-slip texture can enhance the friction of the positioning plate.

[0016] Furthermore, the disassembly and assembly structure includes a mounting plate, a baffle, a screw, a rotating block, and a buckle. The mounting plate is installed at the bottom of the protective shell, and a screw passes through the bottom of the mounting plate. A rotating block is installed on one side of the screw, and a baffle is installed on the other side of the screw. A buckle is installed on one side of the baffle. The screw and the mounting plate form a threaded connection. Rotating the rotating block can drive the screw to rotate. The rotation of the screw will drive the screw and the buckle on one side of the screw to move. The buckle can engage with the connecting block to fix the protective shell on the connecting block.

[0017] Furthermore, the telescopic structure includes a first telescopic rod, a second telescopic rod, and a fixing screw. The first telescopic rod is installed at the bottom end of the base, and a fixing screw is movably connected to one end of the first telescopic rod. The second telescopic rod is movably connected to the bottom end of the first telescopic rod, and the height of the support foot at the bottom end can be adjusted by sliding the second telescopic rod.

[0018] Furthermore, a slider is provided at the top of the second telescopic rod, and a groove is provided inside the first telescopic rod. The second telescopic rod and the first telescopic rod form a sliding structure, and the second telescopic rod can slide inside the first telescopic rod.

[0019] The advantages of the radiation shielding device for a radiation source provided by this utility model are as follows: A protective shell is movably connected to the top of the connecting block, and the protective shell and the connecting block form a locking structure. The protective shell can be inserted into the connecting block, and the protrusion on the inner side of the connecting block will engage with the groove on the outer side of the protective shell. The protrusion will compress the airbag inside the groove. After the airbag is compressed, it can seal the gap between the connecting block and the protective shell, making the connection block and the protective shell more stable. Simultaneously, the screw and the mounting plate form a threaded connection. Rotating the rotating block will drive the screw to rotate, and the rotation of the screw will drive the screw and the latch on one side of the screw to move. The latch can engage with the connecting block, fixing the protective shell onto the connecting block. The baffle can limit the distance the screw moves, thereby achieving the purpose of easily fixing the protective shell in the radiation shielding device for a radiation source.

[0020] By having threaded rods running through both sides and ends of the protective shell, the threaded rods can be rotated by screwing blocks. The threaded rods and the protective shell form a threaded connection. The rotation of the threaded rods can drive the threaded rods to move, and the movement of the threaded rods can drive the positioning plates to move. Multiple positioning plates can clamp the radiating object in the middle and fix the radiating object. The anti-slip texture can enhance the friction of the positioning plates, thereby achieving the purpose of the radiation shielding device for the radiation source to limit the position of the radiating object.
