Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a radiation protection device and method for indoor testing. Background Technology

[0002] As a crucial component of medical facilities, the safety and reliability of other medical piping systems directly impact the quality of healthcare services and patient safety. These systems include, but are not limited to, medical gas pipelines, vacuum suction pipelines, medical compressed air pipelines, and laboratory specialty gas pipelines. Leaks, contamination, or abnormal pressure in any of these systems can lead to serious medical accidents, such as patient hypoxia, cross-infection, or even fire and explosion risks. The inspection of other medical piping systems encompasses several key aspects, with non-destructive testing (NDT) being particularly important to ensure the pipelines' airtightness.

[0003] Existing medical pipeline inspection equipment has the following defects: Since the detection probe emits radiation during pipeline inspection, which is harmful to the human body, most inspection agencies are equipped with protective devices. However, the existing protective devices only protect the surface of the pipeline. There is a gap between the pipeline and the inspection agency, so the protection is not comprehensive enough. Radiation can radiate out through this gap, and complete protection cannot be achieved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a radiation protection device and method for indoor testing. By incorporating protective components and a closing component, it provides comprehensive protection against radiation, aiming to solve the problems in the prior art.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes an indoor radiation protection device, comprising: a base, on which a detection mechanism for detecting pipe welds is installed; the detection mechanism includes a detection component and a pair of protective components located on both sides of the detection component; the detection component includes a rotatable annular track, a lifting rod fixedly connected to the inner side of the annular track, a lifting block fixedly connected to the lower end of the lifting rod, and a detection probe installed on the lifting block; the protective component includes an annular frame, a rotating disk rotatably connected to the surface of the annular frame, a plurality of arc-shaped holes uniformly provided along its circumference on the surface of the rotating disk, and sliding holes corresponding one-to-one with the arc-shaped holes on the annular frame; a slider is slidably connected in the sliding holes, a pair of first lead plates are rotatably connected to the slider, a connecting block is rotatably connected between adjacent first lead plates, and a first sliding shaft is provided on the slider that slidably engages with the arc-shaped holes.

[0006] As a preferred technical solution of the present invention, the protective component is equipped with an opening and closing component, the opening and closing component includes an annular plate, the annular plate is fixedly connected to an annular frame, and a plurality of second lead plates are uniformly slidably connected to the annular plate along its circumference, with adjacent second lead plates in contact with each other, and a second sliding shaft is provided on the second lead plate to slide in cooperation with the arc-shaped hole.

[0007] As a preferred embodiment of the present invention, the surface of the annular plate is provided with guide holes corresponding to the second lead plate, and the surface of the second lead plate is fixedly connected with guide blocks that are slidably connected to the guide holes.

[0008] As a preferred embodiment of the present invention, a plurality of fixed rods are connected between the annular track and the annular frame. One end of the fixed rod is fixedly connected to the annular frame, and the other end of the fixed rod is fixedly connected to a slide block that is slidably connected to the annular track.

[0009] As a preferred embodiment of the present invention, a pair of sliding blocks are slidably connected on the annular track, and a connecting rod is hinged between the sliding blocks and the lifting block.

[0010] As a preferred embodiment of the present invention, a first drive motor is mounted on the base, a first gear is fixedly connected to the shaft of the first drive motor, and a first gear ring that cooperates with the first gear is fixedly mounted on the rotating disk.

[0011] As a preferred embodiment of the present invention, a second drive motor is mounted on the ring frame, a second gear is fixedly connected to the shaft of the second drive motor, and a second gear ring that cooperates with the second gear is fixedly mounted on the ring track.

[0012] As a preferred embodiment of the present invention, a lifting support frame is installed on the base for supporting the pipe. The support frame is provided with a drive wheel and a third drive motor for driving the drive wheel to rotate is installed on the support frame. A lifting rod is installed below the support frame, and a base plate is fixedly connected to the lower end of the lifting rod.

[0013] As a preferred embodiment of the present invention, a flexible protective sleeve is connected to the ring frame and is fitted around the first lead plate.

[0014] A radiation protection method for an indoor testing device includes the following steps: Step 1: Place the medical tubing to be tested inside the testing facility, support the tubing with the support frame, and adjust the testing probe to a suitable height; Step 2: The first drive motor drives the two first gears to rotate. When the first gears rotate, they drive the rotating disk to rotate. When the rotating disk rotates, it drives the first lead plate to rotate, so that the first lead plate contacts the surface of the pipe. At the same time, the rotating disk drives the second lead plate to move. The second lead plate seals the gap between the annular plate and the pipe. Step 3: The third drive motor drives the medical tubing forward, while the second drive motor drives the second gear to rotate, which in turn drives the circular track to rotate, causing the detection probe to perform comprehensive flaw detection on the tubing. During the detection process, the first and second lead plates shield and absorb the radiation emitted by the detection probe, reducing the radiation to the outside world.

[0015] The beneficial effects of this invention are as follows: 1. This invention forms a protective chamber by using a first lead plate and a second lead plate at different positions to effectively absorb and shield the radiation emitted by the detection probe, reduce radiation leakage, and protect the safety of operators; and by using a rotating disk to drive the first lead plate to rotate, it is made to fit against the surface of the medical pipeline, forming a dynamic protective barrier to adapt to the detection needs of different pipe diameters.

[0016] 2. The present invention uses the sliding cooperation of the arc-shaped hole and the slider to allow the first lead plate to adjust its position according to the diameter of the medical pipe, ensuring that the protective effect fits the pipe surface and avoids radiation leakage. The second lead plate slides on the annular plate to further seal the gap between the annular plate and the pipe, thereby enhancing the protective effect. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example: This example discloses an indoor radiation protection device suitable for flaw detection of other medical pipes; such as... Figures 1-9 As shown, the system includes: a base 1, on which a detection mechanism for inspecting pipe welds is mounted; the detection mechanism includes a detection component 2 and a pair of protective components 3 located on both sides of the detection component 2, the protective components 3 being used for radiation protection; wherein, the detection component 2 includes a rotatable annular track 21, with multiple lifting rods 26 fixedly connected to the inner side of the annular track 21, and lifting blocks 28 fixedly connected to the lower ends of the lifting rods 26, with detection probes 27 mounted on the lifting blocks 28, and four sets of detection probes 27 emitting radiation to inspect pipe welds; multiple pairs of sliding blocks 25 are slidably connected to the annular track 21, with connecting rods 29 hinged between the sliding blocks 25 and the lifting blocks 28, and multiple fixed rods 23 connecting the annular track 21 and the annular frame 31, one end of the fixed rod 23 being fixedly connected to the annular frame 31, and the other end of the fixed rod 23 being fixedly connected to a sliding seat 24 slidably connected to the annular track 21, so that the annular track 21 can rotate circumferentially; by moving the sliding blocks 25, the position of the detection probes 27 relative to the pipe can be adjusted to inspect pipes of different diameters.

[0029] like Figures 4-6As shown, the protective component 3 includes a ring frame 31, which is fixedly connected to the base 1. A rotating disk 34 is rotatably connected to the surface of the ring frame 31. The rotating disk 34 has a plurality of arc-shaped holes 36 evenly distributed along its circumference. The ring frame 31 has sliding holes 311 that correspond one-to-one with the arc-shaped holes 36. A slider 37 is slidably connected in the sliding holes 311. A pair of first lead plates 39 are rotatably connected to the slider 37. A connecting block 310 is rotatably connected between adjacent first lead plates 39. The slider 37 is provided with a first sliding shaft 38 that slides in cooperation with the arc-shaped holes 36. The 8 ends are provided with a stop. In this embodiment, the rotating disk 34 has eight sliders 37 and sixteen first lead plates 39. The sixteen first lead plates 39 together form a polygonal star structure. The rotation of the rotating disk 34 can drive the sliders 37 to slide in the sliding hole 311, thereby driving the first lead plates 39 to rotate and change the shape and size of the enclosed area to adapt to pipes of different sizes. Moreover, the polygonal star structure formed by the first lead plates 39 can cause the rays to be reflected and absorbed multiple times after passing through the first lead plates 39, achieving a better shielding effect on the rays.

[0030] like Figures 7-8 As shown, the protective assembly 3 is equipped with an opening and closing assembly 32, which includes an annular plate 321. The annular plate 321 is fixedly connected to the annular frame 31. Multiple second lead plates 322 are evenly slidably connected to the annular plate 321 along its circumference. One end of each second lead plate 322 is triangular, and the other end is arc-shaped. Adjacent second lead plates 322 are in contact with each other. The second lead plates 322 are provided with second sliding shafts 323 that slide in cooperation with arc-shaped holes 36. The surface of the annular plate 321 is provided with guide holes 324 that correspond one-to-one with the second lead plates 322. The surface of each second lead plate 322 is fixedly connected with guide blocks 325 that slide in cooperation with the guide holes 324. When the rotating disk 34 rotates, it drives the second lead plates 322 to slide along the guide holes 324, thereby adjusting the second lead plates 322 to adapt to pipes of different sizes. The second lead plates 322 seal the gap between the pipe and the annular plate 321, preventing radiation leakage.

[0031] Preferably, a first drive motor 4 is mounted on the base 1, a first gear 5 is fixedly connected to the shaft of the first drive motor 4, and a first gear ring 35 that mates with the first gear 5 is fixedly mounted on the rotating disk 34; a second drive motor 6 is mounted on the annular frame 31, a second gear 7 is fixedly connected to the shaft of the second drive motor 6, and a second gear ring 22 that mates with the second gear 7 is fixedly mounted on the annular track 21; the first drive motor 4 drives the two first gears 5 to rotate, and the rotation of the first gears 5 drives the two annular frames 31 to rotate, thereby controlling the position of the first lead plate 39 and the second lead plate 322 to adapt to the protection of pipes of different sizes; the second drive motor 6 drives the second gear 7 to rotate, which drives the annular track 21 to rotate circumferentially, and then drives the detection probe 27 to move circumferentially to detect and inspect the pipe welds.

[0032] like Figures 1-9 As shown, preferably, a lifting support frame 8 is installed on the base 1. The lifting of the support frame 8 is adjusted by a threaded rod. The support frame 8 is used to support the pipeline. A flexible protective sleeve 33 is connected to the ring frame 31 and is fitted around the first lead plate 39. The flexible protective sleeve 33 wraps around the first lead plate 39 to prevent gaps from forming when the first lead plate 39 moves, thereby further reducing the risk of radiation leakage.

[0033] This embodiment also discloses a protection method for an indoor radiation protection device, which, based on the above-mentioned protection equipment, includes the following steps: Step 1: Place the medical tubing to be tested inside the testing facility, support the tubing with the support frame 8, and adjust the testing probe 27 to a suitable height; Step 2: The first drive motor 4 drives the two first gears 5 to rotate. When the first gears 5 rotate, they drive the rotating disk 34 to rotate. When the rotating disk 34 rotates, it drives the first lead plate 39 to rotate, so that the first lead plate 39 contacts the surface of the pipe. At the same time, the rotating disk 34 drives the second lead plate 322 to move. The second lead plate 322 seals the gap between the annular plate 321 and the pipe. Step 3: The third drive motor 82 drives the medical tubing forward, while the second drive motor 6 drives the second gear 7 to rotate. The second gear 7 drives the circular track 21 to rotate in a circle, which in turn drives the detection probe 27 to perform comprehensive flaw detection on the tubing. During the detection process, the first lead plate 39 and the second lead plate 322 shield and absorb the radiation emitted by the detection probe 27, reducing the radiation to the outside world.
