[0035] Figure 1 is a schematic diagram of the structure of a ray testing device provided by an embodiment of the present application, Figure 2 yes Figure 1 The schematic diagram of the exploded structure of the X-ray test device shown in the figure, Figure 3 yes Figure 1 The cross-sectional structure diagram of the ray testing device shown in FIG. Figure 4 is a schematic diagram of the structure of a ray testing device provided by another embodiment of the present application. Figures 1 to 4 The radiation testing device 100 provided in the embodiment of the present application includes a support body 10, a detector assembly 20 and a data acquisition device 30. A detection channel 11 for radiation to pass through is formed inside the support body 10, and the detection channel 11 penetrates the support body 10 along a first direction X. The detector assembly 20 is arranged outside the support body 10 and is located on one side of the support body 10 along the first direction X, and can receive at least part of the radiation emitted from the detection channel 11 and form detection data that can characterize the dose parameters of the radiation. The data acquisition device 30 is arranged outside the support body 10 and is electrically connected to the detector assembly 20 to collect the detection data sent by the detector assembly 20.

[0036] The dose parameter of the ray may be a dose value of the ray, or may be other parameters that can characterize the properties of the ray. Figure 1 , the support body 10 may include at least one support side plate 12 surrounding the detection channel 11. Exemplarily, at least one support side plate 12 may include a support side plate 12, which is an annular cylindrical structure, so as to form an annular internal space in the support body 10, and the detection channel 11 is at least a part of the internal space. Exemplarily, at least one support side plate 12 may include two support side plates 12 arranged opposite to each other along the second direction Y, and the second direction Y intersects with the first direction X. The detection channel 11 is formed between the two support side plates 12. Exemplarily, at least one support side plate 12 may also include four support side plates 12, which are connected in sequence and enclose a square ring-shaped internal space, and the detection channel 11 is at least a part of the internal space. Exemplarily, at least one support side plate 12 may also include three or more support side plates 12.

[0037] Reference Figure 3 and Figure 4 The support body 10 may further include a first end plate 13 and a second end plate 14 that are arranged opposite to each other along the first direction X. The detection channel 11 passes through the first end plate 13 and the second end plate 14. The detector assembly 20 may be arranged on the outer side of the first end plate 13 away from the detection channel 11. The first end plate 13 can increase the support surface area, thereby providing stable support for the detector assembly 20. The second end plate 14 is used to be connected to a radiation source that can emit radiation, so that the radiation can be injected into the detection channel 11. The second end plate 14 can increase the support surface area, thereby improving the support stability of the entire radiation testing device 100, and thereby improving the test accuracy.

[0038] Optionally, refer to Figure 4 The support body 10 may also include a first end plate 13 and a second end plate 14 that are relatively arranged along the first direction X, and a plurality of support columns 16 connected between the first end plate 13 and the second end plate 14 , and the plurality of support columns 16 surround the peripheral side of the detection channel 11 .

[0039] The data acquisition device 30 may include a circuit board and a plurality of electrical components disposed on the circuit board to implement a data acquisition function.

[0040] The number of detector assemblies 20 may be one or more. When the number of detector assemblies 20 is more than one, each detector assembly 20 may be reasonably distributed on one side of the detection channel 11 along the first direction X, so that each detector assembly 20 can receive the radiation emitted from the detection channel 11. Each detector assembly 20 is electrically connected to the data acquisition device 30 to send the detection data acquired by it to the data acquisition device 30. The data acquisition device 30 can organize and summarize the detection data sent by each detector assembly 20, so as to comprehensively judge the dose stability of the radiation source, thereby improving the accuracy of the test results.

[0041] The detector assembly 20 may be connected to one side of the support body 10 along the first direction X. The connection methods between the detector assembly 20 and the support body 10 include but are not limited to screw connection, bonding, clamping, welding, etc.

[0042] The data acquisition device 30 is connected to the outside of the support body 10 , and the connection method between the data acquisition device 30 and the support body 10 includes but is not limited to screw connection, bonding, clamping, welding, etc.

[0043] The ray testing device 100 provided in the embodiment of the present application includes a support body 10, a detector assembly 20 and a data acquisition device 30. A detection channel 11 is formed inside the support body 10, and the detection channel 11 penetrates the support body 10 along the first direction X. The detector assembly 20 is arranged on one side of the support body 10 along the first direction X, and the rays emitted through the detection channel 11 can be irradiated to the detector assembly 20, and the detector assembly 20 receives the rays and generates detection data that can characterize the ray dose. The data acquisition device 30 is electrically connected to the detector assembly 20 outside the support body 10, and can collect the detection data sent by the detector assembly 20, so as to make a comprehensive judgment on the stability of the ray source dose according to the detection data collected. The ray testing device 100 provided in the embodiment of the present application provides the detection channel 11 for the detector assembly 20 through the support body 10, obtains the detection data of the ray dose by using the existing function of the detector assembly 20, and collects the detection data obtained by the detector assembly 20 by using the data acquisition device 30, so as to facilitate the acquisition of accurate test results and realize the basic function of the ray source dose rate test. The price of the support body 10, the detector assembly 20 and the data acquisition device 30 is much lower than that of the existing dosimeter equipment, which greatly reduces the test cost. The acquisition cycle of the detector assembly 20 is usually in the millisecond level, and the acquisition frequency is much higher than that of the existing dosimeter equipment, which can accurately reflect the changes and fluctuations of the radiation source dose rate, thereby improving the test accuracy. The detector assembly 20 operates reliably, is not easily interrupted, and has high test efficiency.

[0044] The support body 10 can also provide support for the detector assembly 20 and the data acquisition device 30, so that the support body 10, the detector assembly 20 and the data acquisition device 30 are integrated together, which is convenient for the movement and transportation of the radiation testing device 100, and improves its convenience of use. The detector assembly 20 and the data acquisition device 30 are both arranged outside the support body 10, which is convenient for disassembly, assembly and replacement.

[0045] In some embodiments, the first direction X is parallel to the vertical direction, and the detector assembly 20 is disposed on the top of the support body 10 .

[0046] The detection channel 11 extending along the first direction X extends vertically, and the radiation emitted by the radiation source is vertically directed upward toward the detector assembly 20 at the top of the support body 10. When installing the radiation testing device 100, the radiation testing device 100 can be directly placed on the surface of the radiation source where the radiation outlet is opened, that is, the radiation source itself can be used to provide a support base for the radiation testing device 100, thereby improving the assembly efficiency and testing efficiency of the radiation testing device 100.

[0047] Moreover, the first direction X is parallel to the vertical direction, which also facilitates the rays to be positively opposite to the detector assembly 20, reducing the possibility of ray path deflection. The detector assembly 20 can be arranged on the top of the support body 10, which is beneficial to the connection stability between the detector assembly 20 and the support body 10.

[0048] In some embodiments, reference Figure 3 The detector assembly 20 includes a detection box 21 and a detector 22. The detection box 21 is provided with a detection port 211, which is connected to the detection channel 11, so that the radiation emitted from the detection channel 11 is at least partially emitted into the detection box 21 through the detection port 211. The detector 22 is arranged in the detection box 21 to receive the radiation emitted from the detection port 211 into the detection box 21 and generate detection data.

[0049] A relatively closed space is defined inside the detection box 21 , and the space is connected to the detection channel 11 only through the detection port 211 , and other positions are closed to improve safety.

[0050] The detection port 211 may be arranged along the first direction X opposite to the detection channel 11 , so that more rays emitted from the detection channel 11 enter the detection box 21 through the detection port 211 , thereby reducing the energy loss of the rays.

[0051] The detection port 211 is disposed on one side of the detection box 21 facing the detection channel 11 along the first direction X. For example, when the first direction X is a vertical direction, the detector assembly 20 may be disposed on the top of the support body 10 , and the detection port 211 may be disposed on the bottom wall of the detection box 21 .

[0052] The detector 22 may be a scintillation detector, which includes a scintillator and a photomultiplier tube. The detection surface of the scintillator is arranged opposite to the detection port 211 along the first direction X, so that the radiation directly irradiates the detection surface of the scintillator. The radiation is incident on the scintillator and absorbed to generate visible light, and the scintillator absorbs the visible light to generate current. The photomultiplier tube is used to integrate and convert the current to form detection data that can characterize the intensity of the radiation.

[0053] The detector 22 may also be other types of detectors, as long as it can form detection data that can characterize the intensity of the rays according to the rays it receives.

[0054] The size of the support body 10 along the first direction X and the opening area of ​​the detection port 211 can be set to match the parameters of the radiation source used in conjunction with the radiation testing device 100, so that the radiation testing device 100 can receive more and more accurately the radiation emitted by the radiation source.

[0055] In some embodiments, the detection box 21 includes a first plate body 212 adjacent to the support body 10 , and the first plate body 212 is provided with a radiation shielding layer 216 capable of shielding radiation.

[0056] The radiation shielding layer 216 may be a lead sheet or a lead layer.

[0057] The radiation shielding layer 216 is laid and adhered to the first plate 212 to shield radiation.

[0058] The detection port 211 may be opened on the first plate 212 , and the radiation shielding layer 216 is disposed in other areas of the first plate 212 except the detection port 211 .

[0059] The inner wall and the outer wall of the first plate body 212 are both provided with a radiation shielding layer 216 to improve the radiation shielding effect.

[0060] The first plate body 212 may be a plate body extending straightly perpendicular to the first direction X, and may be attached to the first end plate 13 of the support body 10 to reduce the gap therebetween.

[0061] The detection box 21 may also include a second plate 213 arranged opposite to the first plate 212 along the first direction X and at least one side plate 214 connected between the first plate 212 and the second plate 213. A radiation shielding layer 216 may also be provided on the second plate 213 and the side plate 214 to further improve the safety protection effect.

[0062] The embodiment of the present application can achieve a better safety protection effect by setting a radiation shielding layer on the first plate 212. Compared with setting the first plate 212 as a lead plate as a whole, it also reduces the weight of the detection box 21, which is conducive to the lightweight of the radiation testing device 100 and facilitates the mobile transportation of the radiation testing device 100.

[0063] In some embodiments, the data acquisition device 30 is disposed on one side of the support body 10 along the second direction Y, and the second direction Y intersects with the first direction X.

[0064] Optionally, the second direction Y may be perpendicular to the first direction X. Exemplarily, the first direction X may be a vertical direction, and the second direction Y may be a direction parallel to the horizontal direction.

[0065] In the embodiment of the present application, the detector assembly 20 is arranged on one side of the support body 10 along the first direction X, and the data acquisition device 30 is arranged on one side of the support body 10 along the second direction Y, so that the detector assembly 20 and the data acquisition device 30 are respectively located on different sides of the support body 10, and the detector assembly 20 and the data acquisition device 30 can be installed and removed respectively without affecting each other. At the same time, the signal interference between the detector assembly 20 and the data acquisition device 30 is also reduced.

[0066] Although the data acquisition device 30 and the detector assembly 20 are independently assembled and disassembled and do not affect each other, it is still necessary to ensure that the data acquisition device 30 and the detector assembly 20 can be electrically connected. The detector assembly 20 and the data acquisition device 30 are located on different sides of the support body 10, but the two positions can be adjacent to each other to facilitate electrical connection between the two.

[0067] In some embodiments, the data acquisition device 30 is connected to the support body 10 and is spaced apart from the support body 10 along the second direction Y.

[0068] The size of the interval formed between the data acquisition device 30 and the support 10 can be selected according to the specific structure of the data acquisition device 30. When selecting, it is preferred that the electrical components of the data acquisition device 30 do not come into contact with the support 10.

[0069] Optionally, refer to Figures 1 to 3 The data acquisition device 30 can be connected to the supporting side plate 12 and spaced apart from the supporting side plate 12. Figure 4 A support plate 18 may be provided on the support column 16 , and the data acquisition device 30 may be connected to the support plate 18 and spaced apart from the support plate 18 .

[0070] In the embodiment of the present application, the data acquisition device 30 is spaced apart from the support body 10 , which can prevent the circuit board and / or electrical components on the data acquisition device 30 from contacting the support body 10 , thereby avoiding the risk of short circuit and improving the reliability of the radiation testing device 100 .

[0071] In some embodiments, the support body 10 is provided with a first connection hole 15 on one side along the second direction Y, the data acquisition device 30 is provided with a second connection hole 31, and the first connection hole 15 is a blind hole with an opening facing the outside of the support body 10. The radiation testing device 100 further includes a connector 40, which is sequentially passed through and connected to the second connection hole 31 and the first connection hole 15.

[0072] The second connection hole 31 penetrates the data acquisition device 30 along the second direction Y so that the connection member 40 can pass through it.

[0073] The first connection hole 15 may have an internal thread, and the connection member 40 has an external thread. The connection member 40 passes through the second connection hole 31 and is threadedly connected to the first connection hole 15 , thereby connecting the data acquisition device 30 to the support body 10 .

[0074] The interior of the second connecting hole 31 may also be provided with an internal thread to improve the connection strength between the second connecting hole 31 and the connecting member 40 .

[0075] The connection member 40 may include a self-tapping screw.

[0076] The connecting member 40 may also be connected to the first connecting hole 15 and the second connecting hole 31 in other ways, such as welding, clamping, form-fitting connection, etc.

[0077] Optionally, refer to Figure 2 and Figure 3 A support side plate 12 may be provided on one side of the support body 10 along the second direction Y, and a first connection hole 15 may be provided on the support side plate 12. The depth of the first connection hole 15 along the second direction Y is less than the thickness of the support side plate 12 along the second direction Y, and the first connection hole 15 extends from the outer wall of the support side plate 12 to the inner wall of the support side plate 12, and the first connection hole 15 does not penetrate the support side plate 12.

[0078] Optionally, refer to Figure 4 The support body 10 may include a plurality of support columns 16 surrounding the detection channel 11, and the first connection hole 15 may be provided on the support plate 18 connected to the support columns 16. The depth of the first connection hole 15 along the second direction Y is less than the thickness of the support plate 18 along the second direction Y, and the first connection hole 15 extends from the outer wall of the support plate 18 to the inner wall of the support plate 18, and the first connection hole 15 does not penetrate the support plate 18.

[0079] In the embodiment of the present application, the first connecting hole 15 used to connect to the connecting piece 40 is set as a blind hole, and the connecting piece 40 will not extend into the interior of the support body 10, thereby ensuring the flatness of the inner surface of the support body 10 and facilitating the laying of a shielding layer such as lead foil on the inner surface of the support body 10.

[0080] In some embodiments, the connector 40 is made of a conductive material and is electrically connected to a ground terminal of the data acquisition device 30 .

[0081] Optionally, the connector 40 may be a metal conductive member with good conductivity. Exemplarily, the connector 40 may include a copper column.

[0082] In the embodiment of the present application, the connector 40 is electrically connected to the ground terminal of the data acquisition device 30 , and the ground terminal of the data acquisition device 30 can be connected to the support body 10 through the connector 40 , thereby ensuring the grounding effectiveness of the data acquisition device 30 and further improving safety and reliability.

[0083] In some embodiments, the detector assembly 20 includes a detection box 21 and a detector 22 disposed in the detection box 21.

[0085] The detection box 21 may include a first plate 212 and a second plate 213 disposed opposite to each other along the first direction X, and a plurality of side plates 214 connected between the first plate 212 and the second plate 213. A wire outlet hole 215 is provided on the side plate 214 on the same side as the data acquisition device 30 along the second direction Y.

[0086] In order to improve the radiation shielding effect, the wire outlet hole 215 can be closely matched with the cable 60. The wire outlet hole 215 can be wrapped with lead.

[0087] In the present application, the wire outlet hole 215 is opened on the side of the detection box 21 adjacent to the data acquisition device 30 along the second direction Y, so that the wire outlet hole 215 and the data acquisition device 30 are in the same lateral position, shortening the distance between the wire outlet hole 215 and the data acquisition device 30, thereby shortening the length of the cable exposed outside the detection box 21, and improving the external neatness of the radiation testing device 100.

[0088] In some embodiments, reference Figure 4 A shielding cylinder 17 capable of shielding radiation is disposed inside the support body 10 , and the shielding cylinder 17 is extended along the first direction X. That is, the axial direction of the shielding cylinder 17 is parallel to the first direction X. The detection channel 11 is formed inside the shielding cylinder 17 and axially penetrates the shielding cylinder 17 .

[0089] The shielding tube 17 can be surrounded by lead sheets.

[0090] The interior of the shielding tube 17 forms a cylindrical annular space, which can shield radially emitted radiation.

[0091] The support body 10 may further include a first end plate 13 and a second end plate 14 that are arranged opposite to each other along the first direction X. The first end plate 13 is provided with a first opening 131, and the second end plate 14 is provided with a second opening 141. The first opening 131 and the second opening 141 are arranged opposite to each other along the first direction X. The projections of the first opening 131 and the second opening 141 in the preset reference plane are both located in the projection of the shielding cylinder 17 in the preset reference plane, and the preset reference plane is perpendicular to the first direction X. Thus, all the rays entering from the first opening 131 or the second opening 141 can enter the shielding cylinder 17, further improving the safety protection effect.

[0092] In the embodiment of the present application, a shielding tube 17 is arranged in the support body 10, and the detection channel 11 is formed inside the shielding tube 17. The radiation only passes through the shielding tube 17, and the entire detection channel 11 can be shielded by the shielding tube 17. There is no need to consider the shielding performance of the support body 10, nor is there any need to consider the safety protection level of the environment in which the radiation testing device 100 is located, thereby improving the flexibility of the use position of the radiation testing device 100.

[0093] In some embodiments, the radiation testing device 100 further includes a processing device (not shown in the figure), which is electrically connected to the data acquisition device 30 to receive the detection data collected by the data acquisition device 30 and output a test result based on the detection data.

[0094] The processing device may be integrated with the data acquisition device 30 , or may be independently provided apart from the data acquisition device 30 .

[0095] The processing device may be electrically connected to the data acquisition device 30 via a cable, or may be electrically connected to the data acquisition device 30 wirelessly.

[0096] The processing device may include a main control board and a display. The main control board is used to receive the detection data collected by the data acquisition device 30 and calculate the test results according to the detection data. The display is used to display the test results calculated by the main control board for easy observation.

[0097] Figure 5 1 is a schematic diagram of the structure of a ray testing device in an embodiment of the present application in a use state. In some embodiments, when the ray testing device 100 is in use, the detection channel 11 may be arranged opposite to the ray outlet 201 of the ray source 200.

[0098] Optionally, the ray testing device 100 may be placed on the ray source 200. The detection channel 11 of the ray testing device 100 vertically penetrates the support body 10, and the lower channel opening of the detection channel 11 is connected to the ray source 200 to allow the rays emitted by the ray source 200 to enter the detection channel 11. Accordingly, the detector assembly 20 may be disposed on the top of the support body 10 to detect the rays emitted from the detection channel 11.

[0099] The ray testing device 100 provided in the embodiment of the present application is not limited to Figure 5 A use state, which may also have other suitable use states, for example, the radiation source 200 is supported above or on the top of the radiation testing device 100, the radiation source 200 is located on other sides of the radiation testing device 100, etc.

[0100] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
