A method for detecting irradiation uniformity and an irradiation dose distribution adjustment device

Abstract

This application belongs to the technical field of irradiation uniformity detection methods, and discloses an irradiation dose distribution adjustment device for irradiation uniformity detection methods. The device includes a base with an adjustment mechanism on the top. The adjustment mechanism includes a support rod. In use, by pulling two handles in sequence, two levers pull two locking blocks downwards. At this time, two springs will be stressed and deformed, entering a stretched state. When the two locking blocks disengage from the two gears, the two gears are unrestricted, allowing the rotation of two connecting plates and two positioning plates to adjust the height and angle of the shielding canopy accordingly. This ensures the entire device is covered by the shielding canopy, preventing the device from being affected by irradiation during use. This structure solves the problem of inconvenient adjustments later on, which arises because the pins, connecting plates, and positioning plates are all connected and positioned by screws.

Description

Technical Field

[0001] This application relates to the technical field of irradiation uniformity detection methods, and more specifically, to an irradiation dose distribution adjustment device for irradiation uniformity detection methods. Background Technology

[0002] Irradiation dose refers to the radiation energy received per unit area per unit time. Radiation processing has a wide range of applications, and it can be combined with various sectors of the national economy to form new industries or new economic growth points. The applications of radiation processing can be summarized into many aspects. The fields that have been industrialized and commercialized include: food irradiation preservation, medical supplies radiation sterilization and disinfection, radiation chemical industry, and waste treatment. Due to its wide range of applications and its close relationship with human life, its dose distribution must be strictly monitored and controlled.

[0003] A search of authorized publication number CN220983510U reveals an irradiation uniformity detection method and an irradiation dose distribution adjustment device, including a base. A support rod is installed at the center of the upper part of the base. A lifting mechanism is set inside the support rod. A fixing component is installed above the lifting mechanism. In the process of use, since the pin, connecting plate and positioning plate are all connected and positioned by screws, it will lead to inconvenience in later adjustment.

[0004] To address the aforementioned issues, this application provides an irradiation dose distribution adjustment device for an irradiation uniformity detection method. Utility Model Content

[0016] In summary, this application includes the following beneficial technical effects:

[0017] In use, by pulling the two handles in sequence, the two levers will pull the two locking blocks downwards. At this time, the two springs will be stressed and deformed, and will be in a stretched state. After the two locking blocks disengage from the two gears, the two gears will be unrestricted, and the two connecting plates and two positioning plates can be rotated to adjust the height and angle of the shielding canopy accordingly, so that the entire device can be covered by the shielding canopy, preventing the device from being affected by radiation during use. Through the above structure, the problem of inconvenient adjustment in the later stage is solved because the pins, connecting plates and positioning plates are all connected and positioned by screws.

[0028] The adjustment mechanism includes a support rod 2, which is fixedly connected to the top of the base 1. A fixing plate 3 is located at the top of the support rod 2. A connecting column 4 is fixedly connected to the top of the fixing plate 3. A support block 5 is fixedly connected to the top of the connecting column 4. A connecting rod 6 is fixedly connected to the top of the support block 5. A pin 7 is fixedly connected to the top of the connecting rod 6. A rotating rod 8 is embedded inside the pin 7. Two connecting plates 9 are fixedly sleeved on the outside of the rotating rod 8. A rotating rod 10 is embedded inside the two connecting plates 9. Two positioning plates 11 are fixedly sleeved on the outside of the rotating rod 10. The tops of the two positioning plates 11 are fixed... A canopy 12 is connected to the front end of the rotating rod 1 8 and the rotating rod 2 10. Gears 13 are fixedly fitted on the outer side of the front end of the two gears 13. A locking block 14 is embedded in the inner side of the two gears 13. A horizontal plate 15 is fitted on the outer side of the bottom of the two locking blocks 14. The two horizontal plates 15 are fixedly connected to the connecting rod 6 and the front connecting plate 9, respectively. A spring 16 is fixedly connected to the bottom of the two horizontal plates 15. A handle 17 is fixedly connected to the bottom of the two springs 16. A pull rod 18 is fixedly connected to the top of the two handles 17. The top of the two pull rods 18 passes through the two springs 16 and is fixedly connected to the two locking blocks 14.

[0029] Please see Figure 1 and Figure 3 The two pull rods 18 are provided with auxiliary components on their outer sides. The auxiliary components include lifting rods 19, which are embedded in the support rods 2 and are fixedly connected to the fixing plate 3.

[0030] Please see Figure 1 and Figure 3 A limit block 20 is fixed at the bottom of the lifting rod 19. A rocker arm 21 is provided on one side of the lifting rod 19. A helical rack 22 is installed on the rocker arm 21. An adjusting screw 23 is threaded into the support block 5. A fixing block 24 is provided at the bottom of the adjusting screw 23.

[0031] Please see Figure 1 and Figure 2 The top of the adjusting screw 23 is fixedly connected to a knob, which is made of non-slip material. The pin 7 is connected to the rotating rod 1 8 by a bearing. The two connecting plates 9 are also connected to the rotating rod 2 10 by bearings.

[0032] The implementation principle of this embodiment is as follows: Place the irradiation dose distribution adjustment device of the irradiation uniformity detection method in a suitable position, loosen the adjustment screw 23, place the shielding object used to adjust the irradiation distribution on the fixed plate 3, tighten the adjustment screw 23, so that the fixed block 24 presses the shielding object, thereby achieving fixation, then shake the rocker arm 21, so that the helical rack 22 rotates and meshes with the lifting rod 19 to achieve lifting and lowering, thereby adjusting the height of the shielding object, thereby adjusting the distribution of irradiation dose;

[0033] Later, by pulling the two handles 17 in sequence, the two levers 18 will pull the two locking blocks 14 downwards. At this time, the two springs 16 will be stressed and deformed, and will be in a stretched state. When the two locking blocks 14 are disengaged from the two gears 13 respectively, the two gears 13 will be unrestricted, and the two connecting plates 9 and the two positioning plates 11 can be rotated to adjust the height and angle of the shielding canopy 12 accordingly, so that the entire device can be covered by the shielding canopy 12, preventing the device from being affected by radiation during use. Through the above structure, the problem of inconvenient adjustment in the later stage is solved because the pin 7, connecting plate 9 and positioning plate 11 are all connected and positioned by screws.
