[0002] Cobalt-60 gamma-ray irradiation sterilization is a technology that uses gamma rays generated by the radioactive isotope cobalt-60 to kill microorganisms. Gamma rays have high energy and can penetrate objects, directly or indirectly destroying the cell nucleus, DNA, or RNA structure of microorganisms, rendering them unable to survive and reproduce, thus achieving a sterilization effect. Therefore, irradiation is a very effective sterilization method. However, irradiation poses significant risks to human health. During use, protective mechanisms are installed on the outside of the drive unit of irradiation sterilization equipment. However, existing protective mechanisms are simple in structure, providing only one layer of protection with poor effectiveness. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-7 In this embodiment of the present invention, a driving device with a gamma ray protection mechanism includes: a support frame 100, two sealing mechanisms 200, a shielding mechanism 300, and an adjusting mechanism 400. A protective shell 110 is fixedly connected to the top of the support frame 100, and a fixing rod 120 is fixedly connected to the top of both ends of the protective shell 110. A fixing frame 130 is fixedly connected to the inner top surface of the protective shell 110, and a fixing plate 140 is fixedly connected to the bottom of the fixing frame 130. A placement groove 141 is opened at both ends of one side of the fixing plate 140. A driving controller 150 is fixedly connected to the inner bottom surface of one end of the fixing frame 130. The two sealing mechanisms 200 are disposed at both ends of the protective shell 110, the shielding mechanism 300 is disposed at the top of the inner side of the protective shell 110, and the adjusting mechanism 400 is fixedly connected to the inner bottom surface of the protective shell 110.

[0043] Specifically, the drive controller 150 facilitates the opening of the irradiation sterilization device body 500, the adjustment mechanism 400 facilitates the carrying and conveying of items, and the two sealing mechanisms 200 facilitate the sealing of both ends of the support frame 100. Furthermore, the two sealing mechanisms 200, the protective shell 110, and the shielding mechanism 300, when closed, work together to shield and absorb the gamma rays emitted when the irradiation sterilization device body 500 is opened, thereby improving the practicality of the drive device with a gamma ray protection mechanism.

[0044] Example 1

[0045] like Figure 3-6 As shown, in this embodiment, the sealing mechanism 200 includes a protective plate 210. The top of the protective plate 210 is rotatably connected to the corresponding fixed rod 120. An opening and closing assembly is provided on one side of the protective plate 210. The opening and closing assembly includes a limiting frame 220, a cylinder 230, and a moving plate 240. The limiting frame 220 is fixedly connected to one side of the protective plate 210. One end of the cylinder 230 is fixedly connected to an inner side wall of the corresponding placement groove 141. The moving plate 240 is slidably connected to one end inside the placement groove 141. A limiting seat 241 is rotatably connected to the outer side of one end of the moving plate 240, and the limiting seat 241 is slidably connected to the inside of the limiting frame 220. Next, the protective shell 110 and the two protective plates 210 are both made of lead-boron polyethylene sheet. The shielding mechanism 300 includes: a first shielding shell 310, two second shielding shells 320 and two second cylinders 330. The first shielding shell 310 is located at the bottom of the fixed plate 140. A rectangular hole 311 is opened on the top of the first shielding shell 310. An adjustment component is provided on one side of the first shielding shell 310. The two second shielding shells 320 are slidably connected to the inside of both ends of the first shielding shell 310. The tops of the two second cylinders 330 are fixedly connected to the bottom of the fixed plate 140, and the output end of the second cylinder 330 is fixedly connected to the top of the first shielding shell 310.

[0046] In this embodiment, the protective shell 110 and the two protective plates 210 are both made of lead-boron polyethylene sheet. A cylinder 230 is used to move the moving plate 240 and the limiting seat 241. The movement of the limiting seat 241 pushes the limiting frame 220, causing the protective plate 210 to deflect, thus opening and closing the protective plate 210. When an item enters the protective shell 110 at an appropriate position, a cylinder 330 is activated, pushing the shielding shell 310 and the two shielding shells 320 downwards. The device moves so that the shielding shell 310 and the two shielding shells 320 cover the outside of the item, and the rectangular hole 311 is slidably connected to the top of the irradiation sterilization device body 500. When the irradiation sterilization device body 500 is turned on, the shielding shell 310 and the two shielding shells 320 are used to shield the gamma rays emitted by the irradiation sterilization device body 500. The protective shell 110 and the two protective plates 210 can also shield and absorb the gamma rays, thus achieving double protection and improving the practicality of the drive device with gamma ray protection mechanism.

[0047] like Figure 5-6As shown, in this embodiment, the adjustment component includes: a rectangular shell 340, a support block 350, two threaded tubes 360, and a motor 370. The rectangular shell 340 is fixedly connected to one side of the shield shell 310, and the support block 350 is fixedly connected to one side of the shield shell 310. One end of the support block 350 is rotatably connected to a bidirectional lead screw 351, and a gear 352 is sleeved and fixed on the outer side of the support block 350. The two threaded tubes 360 are slidably connected to both ends of the rectangular shell 340, and the two threaded tubes 360 are screwed to both ends of the bidirectional lead screw 351. The opposite ends of the two threaded tubes 360 are fixedly connected to a push plate 361, which is fixedly connected to the corresponding shield shell 320. The motor 370 is fixedly connected to an inner sidewall of the rectangular shell 340, and the output end of the motor 370 is fixedly connected to a gear 371, which meshes with the gear 352.

[0048] In specific implementation, by starting motor 370, the second gear 371 is driven to rotate. Motor 370 meshes with the first gear 352, causing the bidirectional lead screw 351 to rotate. This, in turn, causes the threaded tube 360, the push plate 361, and the second shielding shell 320 to move. The two second shielding shells 320 are slidably connected to the inner ends of the first shielding shell 310. The maximum distance that the two second shielding shells 320 can move can be limited by the adjustment component, preventing the two second shielding shells 320 from separating from the first shielding shell 310. By adjusting the position of the two second shielding shells 320, the coverage area of ​​the first shielding shell 310 and the two second shielding shells 320 can be adjusted, which facilitates the adjustment of the protective area of ​​the shielding mechanism 300 and makes it more convenient to use.

[0049] Example 2

[0050] Based on Example 1, the position of the items is adjusted to facilitate the carrying of items that need to be sterilized and to facilitate the transport of the items.

[0051] like Figure 7 As shown, in this embodiment, the adjustment mechanism 400 includes: a fixed base 410, multiple rotating rollers 420, a conveyor belt 430, and a second motor 440. The bottom of the fixed base 410 is fixedly connected to the inner bottom surface of the protective shell 110. The multiple rotating rollers 420 are rotatably connected to the inside of the fixed base 410. The conveyor belt 430 is drivenly connected to the outer side of the multiple rotating rollers 420. A flexible shielding pad 431 is bonded and fixed to the outer side of the conveyor belt 430. The second motor 440 is fixedly connected to one side of the protective shell 110. The output end of the second motor 440 passes through the protective shell 110 and the side wall of the fixed base 410 and is fixedly connected to one end of the corresponding rotating roller 420.

[0052] In specific implementation, by starting motor 440, the corresponding rotating roller 420 is driven to rotate, thereby causing the conveyor belt 430 and the flexible shielding pad 431 to rotate. The rotating conveyor belt 430 and the flexible shielding pad 431 facilitate the carrying of items and the adjustment of the items' position. Furthermore, the flexible shielding pad 431 is used to shield the gamma rays emitted by the irradiation sterilization device body 500, thereby improving the shielding effect against gamma rays.
