[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0027] See also Figure 1-4 An embodiment of a radiation dose measuring device 100 according to an embodiment of the present invention comprises: a slide 10, wherein the slide is provided with a slide rail 11; a detector 20, wherein the detector moves along the slide rail 11 and is used to measure the radiation dose; and a rotating part 30, wherein the rotating part 30 is connected to the slide 10 and is configured to drive the slide 10 to rotate around the axis of the rotating part.

[0028] Specifically, the detector is used to measure the radiation leakage dose from the radiation source, and the slide 10 provides a motion track for the detector 20. On the one hand, the slide is used to carry the detector, and on the other hand, the slide provides the detector with a slide rail 11 that is easy to move. The slide 10 and the slide rail 11 are fixed to each other, for example, by bolts; in order to further expand the measuring range of the detector, a rotating part 30 is connected to the slide 10, and the rotating part 30 drives the slide 10 and then the slide 10 drives the detector 20 to rotate around the axis of the rotating part; thus, the motion trajectory of the detector actually includes two parts: one is moving along the predetermined track of the slide rail, and the other is rotating around its axis with the rotating part; this enables the measuring range of the detector to form a three-dimensional spatial distribution, which is conducive to a more comprehensive detection of the radiation source and improves the reliability of the measurement results.

[0029] The detector can be a common type, such as a scintillation detector, a gas ionization chamber detector, a semiconductor detector, etc. The detector can measure a pulse signal, for example, and convert it into a dose rate representing the radiation intensity through a signal processing module. According to the dose rate, the location where the radiation source has a more serious leakage can be determined, so as to strengthen the use and improvement of the radiation source, thereby improving the safety of the working environment of the staff.

[0030] The slideway can be made of aluminum alloy, or other reinforced designs can be used to ensure that the detector does not deform when moving along the slideway, providing a stable measurement track for the detector. The shape of the slideway can be designed according to the trajectory to be measured, taking into account factors such as the direction of the radiation source ray emission, the distance between the detector and the radiation source, etc.

[0031] The rotating part can have a good supporting effect, so that when the rotating part drives the slideway and the detector to rotate, the detector can perform stable measurement. The rotating part can provide an axis, so that the detector can rotate around the axis, thereby forming a measurement track around the axis space.

[0032] Based on the above examples, please refer to Figure 2 or Figure 3 The slide rail 11 is provided with a slider 12 ; the slider 12 is detachably connected to the detector 20 ; the slider 12 is configured to drive the detector 20 to move on the slide rail 11 .

[0033] Specifically, in order to facilitate installation of the detector on the slide rail and facilitate disassembly and replacement, a slider 12 is provided on the slide rail 11 , and the slider 12 is detachably connected to the detector 20 , and the slider 12 can drive the detector to move on the slide rail 11 .

[0034] It can be understood that the matching relationship between the slider 12 and the slide rail 11 can be, for example, that the slide rail 11 passes through the hollow part of the slider 12, or the slider 12 is snapped onto the slide rail 11, and there is good contact between the slider 12 and the slide rail 11, so that the slider 12 moves stably along the slide rail 11.

[0035] The slider 12 and the detector 20 may be directly connected or indirectly connected through other structures. When directly connected, for example, threaded connection, crimping connection, etc. may be used as long as the connection is detachable.

[0036] like Figure 3In the embodiment, the slider 12 may include a sliding part (not shown) and a bracket 1201. The sliding part may be embedded in the recess of the slide rail 11, and its surface away from the slide rail is connected to the bracket 1201. The bracket 1201 forms a hollow part, which surrounds the slideway 10. A first clamp 1202 is provided on one surface of the bracket, and the clamp can be used to fix the detector 20. Thus, the sliding part and the bracket 1201 drive the detector 20 to move along the slide rail 11.

[0037] Based on the above examples, please refer to Figure 3 The measuring device 100 further includes: a rod 13, a slider 12 connected to the rod 13, a detector 20 disposed on the rod 13, and a position of the detector on the rod 13 can be adjusted.

[0038] Specifically, the detector 20 is connected to the slider 12 through the rod 13, and the position of the detector 20 on the rod 13 is adjustable. For example, the position of the detector 20 on the rod 13 is adjusted to be close to the radiation source or away from the radiation source. Therefore, as the position of the detector 20 changes, its measurement trajectory also changes, further expanding the measurement range.

[0039] like Figure 3 In the figure, the rod 13 is fixed by a first clamp 1202 on a bracket 1201. Furthermore, a second clamp 1301 is also provided on the rod 13, and the second clamp 1301 can be used to connect and fix the detector 20. Furthermore, by changing the position of the first clamp 1202 clamping the rod 13, or by changing the position of the second clamp 1301 on the rod 13, the position of the detector 20 relative to the radiation source can be adjusted. Furthermore, by increasing the number of clamps, for example, two or more detectors can be fixed on the rod 13 at the same time.

[0040] Based on the above examples, please refer to Figure 4 In another embodiment of the measuring device 100, the rotating part 30 includes a coupling 31, a bearing shaft 32, a flange (not shown in the figure), and a support plate 33; the coupling 31 is fixedly connected to the bearing shaft 32, and the bearing shaft 32 is fixedly connected to the support plate 33 through the flange; the support plate 33 is fixedly connected to the slideway 10.

[0041] Specifically, in order to realize that the rotating part 30 drives the slideway 10 to rotate, a coupling 31 is used to realize the transmission rotation. One end of the coupling 31 can be connected to a driving mechanism, for example, to provide a rotation driving force, and the other end is connected to a bearing shaft 32, and the bearing shaft 32 can be further fixed and pressed by a bearing and a bearing pressure plate to provide stability; one end of the bearing shaft 32 is connected to a support plate 33 through a flange, and the support plate 33 is used to be fixedly connected to the slideway 10.

[0042] like Figure 4In the embodiment, the support plate 33 includes, for example, an upper portion 3301 and a lower portion 3302. The upper portion 3301 may be, for example, in the shape of a thin cylinder, which is convenient for connecting with the bearing shaft 32 and transmitting the rotation torque. The lower portion 3302 may be, for example, in the shape of a triangle, which increases the contact and connection area with the slideway to achieve a stable connection. The lower portion 3302 is provided with a hole, for example, for fixing the connection with the slideway by a screw or the like.

[0043] The rotating part may be composed of other structural combinations as long as it can provide a stable rotation effect for the slide.

[0044] Based on the above examples, please refer to Figure 1 or Figure 2 The measuring device 100 further includes: a first motor 40, a coupling 31 connected to the first motor 40, and the first motor 40 is configured to drive the rotating part 30 to drive the slideway 10 to rotate around the axis of the rotating part.

[0045] Specifically, one end of the coupling 31 is connected to the output shaft of the first motor 40, and the first motor 40 is used to provide driving force to drive the rotating part 30 to drive the slide 10 and then the slide 10 drives the detector 20 to rotate; from the above, it can be seen that the rotating part 30 can, for example, provide a central axis, and the detector 20 rotates around the central axis to form circular trajectories of different sizes under driving forces of different sizes.

[0046] For further information, see Figure 1-3 The measuring device 100 may further include: a second motor 50 , the second motor 50 is connected to the slider 12 , and the second motor 50 is configured to drive the slider 12 to drive the detector 20 to move on the slide rail 11 .

[0047] Specifically, the measuring device of the present invention can provide automatic measurement, and uses a motor to drive the detector to measure within a certain range. The first motor 40, for example, drives the rotating part 30 to rotate the detector 20, and the second motor 50 drives the slider 12 to move the detector 20 along the track. Therefore, when the first motor 40 and the second motor 50 work at the same time, the detector 20 can measure along the three-dimensional space distribution, effectively increasing the measurement range, and obtaining a wider range of monitoring of radiation source rays.

[0048] like Figure 3 In the embodiment, the second motor 50 can be fixed on one side of the bracket 1201, so that the second motor 50 can drive the slider 12 to drive the detector 20 to move.

[0049] The rotation speeds of the first motor and the second motor are adjustable, so that the movement speed of the detector on the slide rail can be flexibly controlled.

[0050] Based on the above examples, please refer to Figure 2 or Figure 3A rack 14 is disposed on the slide rail 11 , and a gear (not shown in the figure) is disposed on the second motor 50 . The second motor 50 moves on the rack 14 via the gear.

[0051] As can be seen from the above, the detector reciprocates frequently along the slide rail, and the rotating part drives the detector to rotate. To ensure the stable movement of the detector, a flexible metal rack 14 is provided on the slide rail 11, and a gear is provided on the second motor 50 to reduce the resistance of the second motor 50 to drive the slider to move, so as to achieve continuous and stable movement of the detector. Furthermore, the second motor 50 is supported and restricted by the slide rail 11 and the slider 12, which can resist the centrifugal force generated by the slideway and the detector when rotating with the rotating part, thereby improving the stability of the second motor 50.

[0052] It is understandable that the cooperation between the second motor and the slide rail may also adopt other structures or forms, so that the second motor can achieve the effects of labor saving and stability when driving the slide rail to move.

[0053] Based on the above examples, please refer to Figure 1-3 In another embodiment of the measuring device 100, the slide rail 11 is arc-shaped.

[0054] It can be understood that the shape of the slide rail provides the detector with a motion trajectory along this shape. The shape of the slide rail can be set according to the required measurement range, such as a straight line, an arc, etc. The arc shape can be an arc smaller than a semicircle, an arc larger than a semicircle, etc., and can also be a circle, not limited to those listed above.

[0055] Based on the above examples, please refer to Figure 1-2 The detector 20 is arranged so that its axis always points to the center of the arc during the movement.

[0056] From the above, it can be seen that when the slide rail 11 is set to be arc-shaped, the movement trajectory of the detector 20 along the slide rail 11 is also arc-shaped. For example, the position of the radiation source is set at the center of the arc (or the center of the slide rail). In order to achieve accurate measurement, the detector keeps its end (detection sensitive area) always pointing to the center of the circle during movement. In this way, not only can the location of radiation leakage be quickly detected, but also the accuracy of radiation dose measurement can be improved.

[0057] It can be understood that when the shape of the slide rail is set to other shapes, the axial direction of the detector should correspond to the position of the ray emitted by the radiation source so that the leakage dose can be accurately measured.

[0058] Based on the above examples, please refer to Figure 3 The rod 13 is arranged so that the detector 20 moves along the rod 13 so that the distance between the detector 20 and the center of the circle changes.

[0059] Specifically, the distance between the detector 20 and the radiation source position is adjustable through the rod 13. The extension direction of the rod 13 can be set to point to the center of the circle, for example, so that the detector 20 can have a position close to the center of the circle or a position far from the center of the circle on the rod 13, and the distance from the detector to the center of the circle changes, so that the detector moves along trajectories of different arc sizes, thereby obtaining measurement data along each trajectory.

[0060] Based on the above examples, please refer to Figure 2 In another embodiment of the measuring device 100, the slide rail 11 is symmetrically arranged relative to the rotating part 30; there are two detectors 20, and the two detectors are symmetrically arranged on the slide rail 11; during the movement of the two detectors, the position of one detector remains symmetrical with the position of the other detector relative to the rotating part 30.

[0061] Specifically, multiple detectors can be provided, for example, two detectors are provided, and the two detectors are symmetrically arranged relative to the slide rail and the rotating part, and the positions of the two detectors are always symmetrical with each other during the movement. Thus, two detection signals can be obtained in the same time period, which not only improves the measurement efficiency, but also allows the two signal values ​​to be compared and analyzed for comprehensive judgment to obtain more accurate measurement results.

[0062] It is understandable that the number of detectors is set according to actual needs, and can be set to be symmetrical or asymmetrical, and can be flexibly adjusted.

[0063] Based on the above examples, please refer to Figure 2 In another embodiment of the measuring device, when the detector moves on the slide rail, the rotating part drives the slide rail to rotate around the axis within a range of 0 degrees to 180 degrees.

[0064] Specifically, the rotating part provides the detector with a detection trajectory rotating around the axis of the rotating part, and the rotation range is set according to the measurement requirements. For example, when the number of detectors is set to two, the two left-right symmetrical detectors rotate around the axis at the same time within the range of 0 degrees to 180 degrees; or when only one detector is set, the detector rotates around the axis within the range of 0 degrees to 360 degrees.

[0065] Based on the above examples, please refer to Figure 1 or Figure 2 In another embodiment of the measuring device 100, the measuring device 100 further includes: a platform 60, the platform 60 is arranged between the first motor 40 and the rotating part 30, the first motor 40 is arranged on the platform 60, and the rotating part 30 passes through the platform 60 and is connected to the first motor 40; and a supporting part 70, the supporting part 70 supports the platform 60.

[0066] Specifically, the platform 60 provides a working surface for the measuring device of the present invention, for example, the measuring device is divided into an upper and lower part, the upper part is provided with a first motor 40, and the lower part is connected to the rotating part 30 and the slide 10, the rotating part 30 and the slide 10 are in a suspended state, so that the rotating part 30 drives the slide 10 to rotate around its axis. The support part 70 is used to support the platform 60, and the support part 70 can be, for example, a bracket, and the bracket splicing is reinforced with a crossbeam; the bracket can maintain a certain stability and provide sufficient rotation space for the rotating part 30 and the slide. Further, the radiation source can be, for example, arranged in the rotation space.

[0067] It is understandable that the support bracket can be made of, for example, an aluminum alloy profile, which is light in weight and easy to assemble and disassemble.

[0068] Based on the above examples, please refer to Figure 1 The measuring device 100 also includes: a control system 80, the control system includes a mechanical control module and a data processing module; the mechanical control module is used to control the operation of the first motor and the second motor, and obtain the position information of the detector; the data processing module is used to receive the measurement signal of the detector and perform data processing, and is used to three-dimensionally image the radiation dose according to the position information of the detector and the output signal including the radiation dose information detected by the detector.

[0069] Specifically, the control system can be installed on a computer platform, including mechanical control software and data processing software. The mechanical control software can further include modules such as a user interface to facilitate staff to operate the machine. For example, by controlling the first motor to rotate the detector around the axis, or controlling the second motor to move the detector along the slide rail, thereby locating the position of the detector and obtaining its position information so as to perform measurements within a preset range.

[0070] The data processing software may have functions such as receiving the measurement signal of the detector, data analysis (such as reading the real-time measurement data of the detector, setting the parameters of the detector, and performing statistical analysis of the data results), data storage, and data query (such as users can query historical browsing records and export data). At the same time, it can perform three-dimensional imaging of the radiation dose based on the position information of the detector and the output signal including radiation dose information detected by the detector, and analyze the position with the maximum dose rate based on the three-dimensional coordinates. Thus, the user can obtain the leakage position and leakage dose of the radiation source, which is convenient for improving the use of the radiation source or taking protective measures to improve safety. In addition, the data processing software has a compatible function and can be adapted to different types of detectors, which is convenient for users to change the type of detector and analyze the signal of the detector.

[0071] For further information, see Figure 2A controller C is also provided on the platform 60, and the controller C is configured to convert the instructions of the control system into a form that is easy for the first motor 40 to receive, so as to improve transmission or working efficiency.

[0072] See also Figure 1-4 In a preferred embodiment of the radiation dose measuring device 100 of the present invention, the measuring device 100 includes a slideway 10, the slideway is provided with a slide rail 11, the slideway 10 and the slide rail 11 are semicircular in shape, and the radius of the semicircle can be set to 750-2000mm, for example, the slide rail 11 is provided with a slider 12, one end of the slider 12 is connected to the second motor 50, and the other end is connected to the detector 20, the second motor 50 drives the slider 12 to drive the detector 20 to move on the slide rail 11; the rotating part 30 is vertically connected to the center position of the semicircular slideway 10, that is, the slideway 10 is left-right symmetrical with respect to the rotating part 30, and the rotating part 30 can provide a vertical axis, so that the rotating part 30 drives the slideway 10 to rotate around the axis; the upper end of the rotating part 30 is connected to the first motor 40, and the first motor 40 is used to drive the rotating part 30 to drive the detector to rotate around the axis; the measuring device also includes a platform 60, a support part 70 and a control system 80.

[0073] The above-mentioned semicircular slide and slide rail can be formed by splicing multiple arc sections, for example, the slide is composed of 4 sections of 45° arcs, and the slide rail is composed of 3 sections of 60° arcs; the slide is made of aluminum alloy, and the slide rail is made of steel; the slide and the slide rail are fixed by bolts, for example.

[0074] Furthermore, the number of detectors 20 is set to two, which are respectively arranged on the slide rails on both sides of the rotating part 30, and the positions of the two detectors are always kept symmetrical; the detector 20 is arranged perpendicular to the slider 12, and the axial direction of the detector always points to the center of the semicircle. Figure 3 Each detector can reciprocate along the slide rail, for example, from 0 degrees (the detector axis points horizontally to the center of the circle) to 90 degrees (the detector axis points vertically to the center of the circle), and then from 90 degrees to 0 degrees; by controlling the rotation speed of the second motor 50, the movement speed of the detector can be adjusted, for example, from 0 degrees to 90 degrees, and the one-way movement time can be continuously adjusted from 1s to 60s.

[0075] Furthermore, the distance from the detector to the center of the circle is adjusted by the rod 13. The rod 13 is connected to the slider 12, and its extension direction, for example, points to the center of the circle. The detector can be close to or away from the center of the circle at different positions along the rod 13. For example, the distance from the detector to the center of the circle is adjusted in the range of 0-500mm, so that the movement (measurement) trajectory of the detector includes multiple semicircles of different sizes.

[0076] Furthermore, when the two detectors move along the semicircular orbit at the same time (the positions of the two detectors are always symmetrical relative to the rotating part 30), the rotating part 30 provides rotation around the axis in the range of 0 degrees to 180 degrees, and the distance from the detector to the center of the circle is adjustable, so that the measurement range of the detector forms a hemispherical spatial distribution, which greatly enriches the measurement range of the detector. Compared with the measurement range of a two-dimensional plane, the measurement data obtained by the present invention is more accurate.

[0077] In this embodiment, the radiation source position is set at the center of the hemispherical space, for example, and the radiation source can be, for example, an X-ray machine; the X-ray leakage dose (rate) is measured through the measurement trajectory of the above-mentioned detector, and the leakage dose (rate) is displayed on the hemispherical surface in the form of a cloud map, so that the measurement result is more intuitive, so as to obtain the position where the leakage dose (rate) is the largest.

[0078] In this embodiment, the detector can measure a range of, for example, 20 keV to 1250 keV, and can obtain a dose rate measurement range of 0.2 μSv / h to 10 Sv / h.

[0079] In this embodiment, control software is used to achieve mechanical positioning of the measuring device (positioning accuracy 1°), receive measurement signals from the detector, and analyze the measurement data.

[0080] The measuring device of the above-mentioned embodiment realizes automatic measurement of the detector through a control system, and has the characteristics of high sensitivity, good stability and a wide linear range of dose rate measurement. By performing three-dimensional imaging of the leakage dose, it is convenient to quickly determine the leakage location or leakage point, thereby improving the intuitiveness of the measurement results and playing an important role in the safety detection of radiation sources.

[0081] The measuring device of the above embodiment can provide factory inspection services for X-ray machines (including: X-ray flaw detectors, medical X-ray machines and other X-ray machines, etc.) to ensure whether the leakage dose of the X-ray machine exceeds the provisions of the relevant standards, and can quickly find the leakage point to provide technical support for the protection of radiation workers.

[0083] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. The protection scope of the present invention shall be based on the protection scope of the claims.
