Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology, specifically relating to an X-ray air kerma rate measuring device. Background Technology

[0002] An X-ray air kerma rate meter is a device specifically designed to measure X-ray radiation dose. It calculates radiation intensity by measuring the kinetic energy released by radiation onto the air. It is commonly used in radiation protection and medical fields to monitor and assess the radiation environment. When X-rays collide with atoms in the air, they release electrons; the energy of these electrons forms "kerma rate." The X-ray air kerma rate meter assesses the intensity and dose of X-ray radiation by measuring the kinetic energy of these electrons in the air.

[0003] According to the public announcement (CN222461691U), an X-ray and gamma-ray radiation air kerma rate measuring device is disclosed.

[0012] In a preferred embodiment of the X-ray air kerma rate measuring device of this utility model, a movable ring is rotatably connected to the outer wall of the end of the extension rod away from the bent rod. The movable ring has symmetrically provided first connecting holes. A threaded ring is fixedly connected to the movable ring near any one of the first connecting holes. A second annular plate is fixedly connected to the inner wall of the measuring rod near the movable ring. A threaded rod is rotatably connected to the second annular plate near the threaded ring. The threaded rod passes through the nearest first connecting hole and is threadedly connected to the threaded ring. The end of the threaded rod away from the second annular plate is rotatably connected to the first annular plate.

[0013] In a preferred embodiment of the X-ray air kerma rate measuring device of this utility model, a second connecting hole is provided on the second annular plate near the threaded rod, and a drive motor is installed on the second annular plate near the second connecting hole. The output shaft of the drive motor passes through the second connecting hole and is fixedly connected to the threaded rod.

[0014] In a preferred embodiment of the X-ray air kerma rate measuring device of this utility model, a guide rod is fixedly connected to the side of the second annular plate away from the threaded rod. The guide rod passes through the adjacent first connecting hole, and the end of the guide rod away from the second annular plate is fixedly connected to the first annular plate.

[0015] As a preferred embodiment of the X-ray air kerma rate measuring device of this utility model, the first annular plate is provided with an adjustment structure;

[0016] The adjustment structure includes a fixed ring, which is fixedly connected to the side of the first annular plate near the bent rod.

Then, the operator can use a lever to drive the rotating ring to rotate. When the rotating ring rotates, the extension rod will rotate together under the action of the connecting block and the connecting groove, thereby causing the extension rod to drive the bent rod to rotate together, adjusting the position of the probe. After the adjustment is completed, the hand-tightening bolt is turned again to enter the nearby threaded hole, limiting the rotating ring and fixing the position of the bent rod and the probe, reducing the measurement difficulty and facilitating measurement at different positions.

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.

[0032] Example 1

[0033] In the prior art, the existing measuring device includes a measuring instrument body 1 and a measuring rod 2 installed on the measuring instrument body 1. This measuring device also includes a second monitoring rod that is slidably inserted into the first monitoring rod through a lead screw, and a detector is provided at one end of the second monitoring rod. A protective rib is provided on the outer side of one end of the radiation air kerma rate meter body. A lead screw is rotatably mounted on the inner wall of the first monitoring rod through a support plate. One end of the first monitoring rod is threadedly connected to the lead screw through a limiting slider. A servo motor is driven to one end of the lead screw, so that the forward and reverse rotation of the lead screw is adjusted by the servo motor, thereby moving and adjusting the second monitoring rod. The adjustment operation is convenient and quick, and the accuracy is high.

[0034] This application incorporates the aforementioned prior art, such as Figures 1 to 6 As shown, this utility model provides a technical solution: an X-ray air kerma rate measuring device, wherein an extension structure 3 is provided on the measuring rod 2, the extension structure 3 includes a first annular plate 31, the first annular plate 31 is fixedly connected to the end of the measuring rod 2 away from the measuring instrument body 1, an extension rod 32 is provided on the inner side of the first annular plate 31, the extension rod 32 is disposed inside the measuring rod 2, a first connecting ring 33 is fixedly connected to the outer wall of the end of the extension rod 32 away from the measuring instrument body 1, a bent rod 34 is fixedly connected inside the first connecting ring 33, a third connecting ring 36 is fixedly connected to the outer wall of the end of the bent rod 34 away from the first connecting ring 33, and a third connecting ring 36 is fixedly connected inside the third connecting ring 36. The probe head 37 and the bent rod 34 are fixedly connected to a second connecting ring 35 at one end near the first connecting ring 33. The outer wall of the second connecting ring 35 is provided with an external thread, and the inner wall of the first connecting ring 33 is provided with an internal thread. The first connecting ring 33 and the second connecting ring 35 are threaded together. The bent rod 34 is fixedly connected to the first connecting ring 33 through the second connecting ring 35. A fourth connecting ring 38 is fixedly connected to the bottom surface of the probe head 37. The outer wall of the fourth connecting ring 38 is provided with an external thread, and the inner wall of the third connecting ring 36 is provided with an internal thread. The third connecting ring 36 and the fourth connecting ring 38 are threaded together. The probe head 37 is fixedly connected to the third connecting ring 36 through the fourth connecting ring 38.

[0035] In this implementation scheme: by setting a bent rod 34 on the extension rod 32 and installing the probe 37 on the bent rod 34, the measuring device can send the probe 37 into corners or gaps during use, which is convenient for operators. Furthermore, by setting the first connecting ring 33, the second connecting ring 35, the third connecting ring 36, and the fourth connecting ring 38, the bent rod 34 and the probe 37 can be quickly disassembled, which is convenient for replacement and maintenance of the bent rod 34 and the probe 37.

[0036] Furthermore:

[0037] like Figures 3 to 6 As shown;

[0038] Based on the above:

[0039] To facilitate use in different scenarios, in an optional embodiment, the fourth connecting ring 38 is the same size as the second connecting ring 35, and the third connecting ring 36 is the same size as the first connecting ring 33.

[0040] In this embodiment: Since the size of the fourth connecting ring 38 is the same as that of the second connecting ring 35, and the size of the third connecting ring 36 is the same as that of the first connecting ring 33, when the bent rod 34 is not required, the fourth connecting ring 38 can be connected to the first connecting ring 33, so that the probe 37 can be directly mounted on the extension rod 32, and the measuring device can adapt to different usage scenarios.

[0041] Furthermore:

[0042] like Figures 2 to 4 As shown;

[0043] Based on the above:

[0044] In an optional embodiment, to move the extension rod 32, a movable ring 39 is rotatably connected to the outer wall of the end of the extension rod 32 away from the bent rod 34. The movable ring 39 has symmetrically provided first connecting holes 310. A threaded ring 311 is fixedly connected to the movable ring 39 near any one of the first connecting holes 310. A second annular plate 312 is fixedly connected to the inner wall of the measuring rod 2 near the movable ring 39. A threaded rod 313 is rotatably connected to the second annular plate 312 near the threaded ring 311. The threaded rod 313 passes through the nearby first connecting hole 310 and is threadedly connected to the threaded ring 311. The end of the threaded rod 313 away from the second annular plate 312 is rotatably connected to the first annular plate 31. A second connecting hole 315 is provided on the second annular plate 312 near the threaded rod 313. A drive motor 316 is installed on the second annular plate 312 near the second connecting hole 315. The output shaft of the drive motor 316 passes through the second connecting hole 315 and is fixedly connected to the threaded rod 313.

[0045] In this embodiment: when it is necessary to move the extension rod 32, the drive motor 316 can be started, so that the drive motor 316 drives the threaded rod 313 to rotate. When the threaded rod 313 rotates, it will drive the moving ring 39 to move, so that the moving ring 39 drives the extension rod 32 to move together, thereby adjusting the extension length of the extension rod 32.

[0046] Furthermore:

[0047] like Figure 3 and Figure 4 As shown;

[0048] Based on the above:

[0049] In order to guide the moving ring 39, in an optional embodiment, a guide rod 314 is fixedly connected to the side of the second annular plate 312 away from the threaded rod 313. The guide rod 314 passes through the adjacent first connecting hole 310, and the end of the guide rod 314 away from the second annular plate 312 is fixedly connected to the first annular plate 31.

[0050] In this embodiment, the movement of the moving ring 39 can be guided by the guide rod 314 to prevent the moving ring 39 from deviating.

[0051] Furthermore:

[0052] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown;

[0053] Based on the above:

[0054] In order to adjust the orientation of the bent rod 34, in an optional embodiment, an adjustment structure 4 is provided on the first annular plate 31;

[0055] The adjusting structure 4 includes a fixed ring 41, which is fixedly connected to the side of the first annular plate 31 near the bent rod 34. A rotating ring 42 is rotatably connected to the inner wall of the fixed ring 41. Several connecting blocks 43 arranged in a ring are fixedly connected to the inner wall of the rotating ring 42. A connecting groove 44 is provided on the extension rod 32 near each connecting block 43. The connecting blocks 43 are respectively set in the nearby connecting grooves 44. A lever plate 45 is fixedly connected to the side of the rotating ring 42 away from the first annular plate 31. A third connecting hole 46 is provided on the lever plate 45. Several threaded holes 48 arranged in a ring are provided on the fixed ring 41. A hand-tightening bolt 47 is provided in the third connecting hole 46. The hand-tightening bolt 47 is threadedly connected to the nearby threaded hole 48.

[0056] In this embodiment: when it is necessary to adjust the orientation of the bent rod 34, the hand-tightening bolt 47 can be rotated to disengage it from the threaded hole 48, so that the hand-tightening bolt 47 no longer limits the rotation ring 42. Then, the operator can use the lever 45 to drive the rotation ring 42 to rotate. When the rotation ring 42 rotates, the extension rod 32 will rotate together under the action of the connecting block 43 and the connecting groove 44, thereby causing the extension rod 32 to drive the bent rod 34 to rotate together, adjusting the position of the probe head 37. After the adjustment is completed, the hand-tightening bolt 47 is rotated again to enter the nearby threaded hole 48, limiting the rotation ring 42, thereby fixing the position of the bent rod 34 and the probe head 37, reducing the measurement difficulty and facilitating measurement at different positions.

[0057] The working principle and usage process of this utility model are as follows: In use, the operator first adjusts the extension length of the extension rod 32 according to the usage scenario. Then, the drive motor 316 is started, causing the threaded rod 313 to rotate. When the threaded rod 313 rotates, it drives the moving ring 39 to move, causing the extension rod 32 to move together, thus adjusting the extension length of the extension rod 32. Next, the orientation of the bent rod 34 is adjusted as needed. The hand-tightening bolt 47 is rotated to disengage from the threaded hole 48, so that the hand-tightening bolt 47 no longer limits the rotation ring 42. Then, the operator can use the lever 45 to rotate the rotation ring 42. When the rotation ring 42 rotates, the extension rod 32 rotates together under the action of the connecting block 43 and the connecting groove 44, thus causing the extension rod 32 to drive the bent rod 34 to rotate together, adjusting the position of the probe head 37. After adjustment, the hand-tightening bolt 47 is rotated again, causing it to enter the nearest threaded hole 48. In the middle, the rotating ring 42 is limited to fix the position of the bent rod 34 and the probe 37. Then, the operator can use the measuring instrument body 1 to make measurements. Since the bent rod 34 is set on the extension rod 32 and the probe 37 is installed on the bent rod 34, the measuring device can send the probe 37 into corners or gaps during use, which is convenient for operators. Furthermore, by setting the first connecting ring 33, the second connecting ring 35, the third connecting ring 36 and the fourth connecting ring 38, the bent rod 34 and the probe 37 can be quickly disassembled, which is convenient for replacement and maintenance of the bent rod 34 and the probe 37. The size of the fourth connecting ring 38 is the same as the size of the second connecting ring 35, and the size of the third connecting ring 36 is the same as the size of the first connecting ring 33. When the bent rod 34 is not needed, the fourth connecting ring 38 can be connected to the first connecting ring 33, so that the probe 37 can be directly installed on the extension rod 32, making the measuring device adaptable to different usage scenarios.

[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
