However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

It should be noted that the terms used herein should be interpreted in a manner consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.
[0030] The following is for reference. Figures 1-3 A test apparatus 100 for measuring the radiation angle of a radiation source according to an embodiment of the present invention is described.
[0031] like Figure 1 and Figure 2 As shown, the X-ray source radiation angle testing device 100 according to an embodiment of the present invention includes a detector clamping device 1, a control device 3, and a shielding device 2.
[0032] Specifically, in combination Figure 1 and Figure 2 The detector clamping device 1 is configured to rotate within a preset angle S, suitable for clamping the detector; the control device 3 is communicatively connected to the detector clamping device 1; the shielding device 2 is disposed between the detector clamping device 1 and the control device 3.
[0033] It is understandable that when measuring the radiation angle of the radiation source to be tested, the test equipment 100 can be placed in front of the radiation source to be tested.
[0034] According to the X-ray source radiation angle testing device 100 of this utility model embodiment, a detector clamping device 1 can clamp a detector, which can be used to receive the X-rays emitted by the X-ray source under test and record the radiation dose. The detector clamping device 1 can rotate within a preset angle S, which can move the detector to any position within the preset angle S. Thus, the detector can record the radiation dose radiated by the X-ray source under test to any position within the preset angle S range, and the radiation angle of the X-ray source under test can be calculated according to the radiation angle algorithm. The control device 3 can be used to control the rotation of the detector clamping device 1 within the preset angle S. Thus, the detector clamping device 1 drives the detector to collect radiation dose with high efficiency and high accuracy through electronic control. The testing personnel can operate the control device 3 to make the detector clamping device 1 rotate within the preset angle S. The shielding device 2 is set between the detector clamping device 1 and the control device 3 to shield the testing personnel from radiation damage.
[0035] According to some embodiments of this utility model, such as Figure 3 As shown, the detector clamping device 1 includes a base 11 and a swing arm assembly 12. The swing arm assembly 12 is rotatably connected to the base 11 and is communicatively connected to the control device 3, suitable for clamping the detector. It can be understood that the base 11 can facilitate fixing the swing arm assembly 12. Under the control of the control device 3, the swing arm assembly 12 can rotate within a preset angle S, thereby enabling the detector to receive radiation at any position within the preset angle S.
[0036] According to some embodiments of this utility model, such as Figure 3As shown, the swing arm assembly 12 includes a drive motor 121 and a swing arm 122. The housing of the drive motor 121 is mounted on the base 11, and the drive motor 121 is communicatively connected to the control device 3. The swing arm 122 is connected to the output end of the drive motor 121 and is suitable for holding the detector. It can be understood that the control device 3 can control the rotation of the drive motor 121, which in turn drives the swing arm 122 to rotate via its output end, thereby enabling the detector to receive radiation at any position within a preset angle S. The drive motor 121 and the swing arm 122 facilitate the function of the swing arm assembly 12: under the control of the control device 3, it can rotate within a preset angle S, thereby enabling the detector to receive radiation at any position within the preset angle S.
[0037] According to some embodiments of this utility model, such as Figure 3 As shown, the swing arm 122 includes a connecting assembly 1221 and a gripper 1222. One end of the connecting assembly 1221 is connected to the output end of the drive motor 121; the gripper 1222 is connected to the other end of the connecting assembly 1221 and is suitable for gripping the detector. It can be understood that the drive motor 121 can drive the connecting assembly 1221 to rotate through its output end, the gripper 1222 can be used to hold and fix the detector, and the connecting assembly 1221 can use the gripper 1222 to move the detector to any position within a preset angle S to receive radiation.
[0038] According to some embodiments of this utility model, the connecting component 1221 includes a connecting rod that extends vertically and retractably. One end of the connecting rod is connected to the output end of the drive motor 121, and the other end is connected to the gripper 1222. It is understood that the drive motor 121 can drive the connecting rod to rotate via its output end, and the gripper 1222 can be used to hold and fix the detector. The connecting rod can drive the detector to receive radiation at any position within a preset angle S via the gripper 1222. The vertical retraction of the connecting rod allows adjustment of the detector's position in the vertical direction (height direction), better adapting to the radiation source to be tested and improving detection convenience and efficiency.
[0039] According to some embodiments of this utility model, such as Figure 3As shown, the connecting assembly 1221 includes a first connecting rod 12211 and a second connecting rod 12212. The first connecting rod 12211 extends vertically, with one end connected to the output end of the drive motor 121. The second connecting rod 12212 extends horizontally, with one end connected to the other end of the first connecting rod 12211 and the other end connected to the gripper 1222. It can be understood that the height of the first connecting rod 12211 and the length of the second connecting rod 12212 can be designed according to actual needs. The first connecting rod 12211 can fix the detector at the required height, and the second connecting rod 12212 can fix the detector at the required distance from the radiation source to be tested, thereby better adapting to the radiation source and improving detection convenience and efficiency.
[0040] According to some embodiments of this utility model, the first connecting rod 12211 extends retractably in the vertical direction, and / or the second connecting rod 12212 extends retractably in the horizontal direction. It is understood that the vertical retraction of the first connecting rod 12211 allows adjustment of the detector's position in the vertical direction (height direction), and the horizontal retraction of the second connecting rod 12212 allows adjustment of the distance between the detector and the radiation source to be tested. This allows for more flexible adjustment of the detector's position, better adaptation to the radiation source to be tested, and improved detection convenience and efficiency.
[0041] According to some embodiments of this utility model, the gripper 1222 has a four-claw structure, with the four claws distributed in the four directions of up, down, left, and right. Therefore, the gripper 1222 can limit the detector in the four directions, making the fixation of the detector more stable.
[0042] According to some embodiments of this utility model, such as Figure 3 As shown, the swing arm 122 is connected to the output end of the drive motor 121 via a tensioning sleeve shaft 13. The tensioning sleeve can improve the stability and reliability of the connection between the swing arm 122 and the output end.
[0043] According to some embodiments of this utility model, the control device 3 includes a display screen and a processor. The display screen includes operation buttons; the processor is communicatively connected to both the display screen and the detector clamping device 1. Thus, the inspector can issue various inspection-related commands through the operation buttons on the display screen. Upon receiving the commands, the processor controls the detector clamping device 1 according to the commands, thereby enabling it to rotate within a preset angle S.
[0044] In some embodiments, the control device 3 can be communicatively connected to the radiation source, thereby controlling the emission and cessation of the radiation beam.
[0045] In some embodiments, the control device 3 can be communicatively connected to the detector, thereby controlling the detector to collect radiation dose.
[0046] According to some embodiments of this utility model, by placing the shielding device 2 between the detector clamping device 1 and the control device 3, the radiation emitted during testing can be effectively prevented from irradiating the testing personnel. Simultaneously, placing the control device 3 in front of the shielding device 2 ensures that the detector clamping device 1 can be operated at any time, improving testing efficiency.
[0047] The detector is fixed to the output end of the drive motor 121 by the gripper 1222 and the connecting component 1221. The control device 3 controls the drive motor 121 to drive the connecting component 1221 and the detector to reciprocate within a preset angle S. The preset angle S can be, for example, 120°.
[0048] The steps for testing the radiation angle of the X-ray source are as follows.
[0049] Place the X-ray source to be tested into the detector clamping device and connect the power supply; no beam will be emitted at this time.
[0050] The testing personnel retreated outside the shielding device and operated the detector clamping device to a -60° angle. At this point, the radiation source to be tested was turned on, and then the program was started to rotate the arm at a uniform angular velocity to 60°. The detector recorded the radiation dose in real time during the rotation.
[0051] The controller reads the radiation dose value recorded by the detector and calculates the radiation angle range based on the rotational angular velocity value of the detector clamping device.
