[0002] The basic principle of radioactive source positioning is based on the basic characteristics that the rays emitted by alpha sources, beta sources, gamma sources and neutron sources have different characteristics. Taking gamma rays as an example, gamma sources emit gamma photons to the surrounding space, and these photons have isotropic characteristics. By detecting the intensity and direction of these photons, the position of the radioactive source can be inferred.
[0003] The radioactive source positioning device in the prior art usually adopts a fixed height mode for acquisition, which makes the detection efficiency low and has certain limitations. Specifically, the design of fixed height limits the effective coverage range of the equipment; since the position and distribution of radioactive sources are usually uncertain, a single height detection method cannot comprehensively cover the potential radioactive source position, which may easily miss important information, thereby affecting the accuracy of the detection result.

[0046] The support 2 is provided with a driving assembly for driving the lead screw 3 to rotate. The driving assembly comprises a controller and a rotating member screw-fixedly connected to the support 2, and the rotating member in this embodiment is a motor 8, which is preferably a 17HS4023; the controller is preferably an STM32F407VG; the output end of the controller is electrically connected with the input end of the motor 8; and the output shaft of the motor 8 is coaxially fixedly connected with the lead screw 3.
[0047] The lead screw 3 is provided with a limiting assembly for limiting the movement stroke of the nut seat 4. The limiting assembly comprises a fixed rod 9 and a limiting block 10 rotationally fitted on the outer wall of the lead screw 3, and the fixed rod 9 is screw-fixedly connected to the top of the limiting block 10; the top end of the fixed rod 9 penetrates through the nut seat 4 and is screw-fixedly connected with the support 2.
[0048] The lead screw 3 is also provided with a surrounding assembly for enabling the detector 1 to rotate around the moving ring 5. The surrounding assembly comprises a rotating disc 11 and an extension rod 12, the rotating disc 11 is coaxially fixedly connected with the output shaft of the motor 8; the extension rod 12 is screw-fixedly connected to the top of the rotating disc 11, and the top end of the extension rod 12 is screw-fixedly connected with the detector 1.
[0049] The outer wall of the support 2 is also provided with a handle 7, and the connecting part of the support 2 and the handle 7 is provided with a folding assembly for folding the handle 7. The folding assembly comprises a connecting plate 13 and a rotating ring 14, the connecting plate 13 is screw-fixedly connected to the outer wall of the support 2; the connecting plate 13 is symmetrically hinged with a movable block 15, the handle 7 is screw-fixedly connected to the outer wall of the rotating ring 14; the rotating ring 14 is integrally formed with a first clamping tooth 16 on both sides thereof, and the movable block 15 is integrally formed with a second clamping tooth 17 meshing with the first clamping tooth 16.
[0050] The movable block 15 is provided with a clamping assembly for engaging the first clamping tooth 16 and the second clamping tooth 17.

[0051] The specific implementation process is as follows:
[0052] Firstly, before the radioactive source positioning detection is performed, the handle 7 is rotated out of the support 2, since the output shaft of the motor 8 is coaxially fixedly connected with the screw rod 3, the screw rod 3 can be driven to rotate by the motor 8, thereby realizing efficient power transmission effect.
[0053] Since the nut seat 4 is threadedly matched with the screw rod 3, the connecting rod 6 is screw-fixedly connected to the nut seat 4, and the other end of the connecting rod 6 is screw-fixedly connected with the moving ring 5; therefore, the nut seat 4 can be vertically moved by the rotation of the screw rod 3. The design of the fixed rod 9 makes the nut seat 4 not deviate when moving, thereby improving the stability of the linear motion. When the nut seat 4 moves, the moving ring 5 is also vertically moved, thereby realizing the adjustment of the height position of the detector 1, and meeting the detection requirements at different heights.
[0054] Since the detector 1 is slidingly matched with the outer wall of the moving ring 5, the telescopic rods 12 are screw-fixedly connected with the rotating disc 11 and the detector 1 respectively, and the rotating disc 11 is coaxially fixedly connected with the output shaft of the motor 8; therefore, when the rotating disc 11 is driven to rotate by the motor 8, the detector 1 is driven to rotate around the moving ring 5 by the telescopic rods 12, thereby meeting the requirements of the multi-directional radioactive source positioning information detection.
[0055] The spring 18 can support the movable block 15 to be opened to both sides, and the eccentric design of the push block 20 can change the extrusion degree of the push block 20 on the movable block 15, so that the first clamping tooth 16 can be engaged or disengaged with the second clamping tooth 17, thereby realizing the adjustment function of the angle of the handle 7. Figure 2 For example, when the push block 20 is rotated clockwise to be parallel, the gap between the point of the eccentric rotation matching of the cross rod and the push block 20 and the movable block 15 becomes smaller, the spring 18 lifts up the movable block 15, so that the first clamping tooth 16 and the second clamping tooth 17 are disengaged, the angle of the handle 7 can be adjusted when the first clamping tooth 16 and the second clamping tooth 17 are disengaged, and the first clamping tooth 16 and the second clamping tooth 17 can be engaged after the handle 7 is adjusted to the required position, thereby fixing the handle 7 and meeting the folding storage requirements.

[0058] The specific implementation process is as follows: Through the design of the card block 21, the detector 1 can remain stable when rotating around the moving ring 5.
[0059] Example 3:
[0060] As attached Figure 1 As shown, the difference from the above embodiment is that the outer wall of the handle 7 is also fixedly bonded with an anti-slip sleeve 22.
[0061] The specific implementation process is as follows: The anti-slip sleeve 22 is designed to increase the friction of the handle 7 and reduce the slippage when holding the handle 7.
[0062] Example 4:
[0063] As attached Figure 1 As shown, the difference from the above embodiment is that the display screen 23 is fixedly connected to the outer wall of the bracket 2 with screws. In this embodiment, the display screen 23 is preferably model ILI9341; the controller output terminal is electrically connected to the display screen 23 input terminal.
[0064] The specific implementation process is as follows: The display screen 23 is designed to display the parameters collected by the detector 1.
[0065] Example 5:
[0066] As attached Figure 1 As shown, the difference from the above embodiment is that a buzzer 24 is also embedded in the outer wall of the bracket 2. In this embodiment, the buzzer 24 is preferably of model KY-012; the output terminal of the controller is electrically connected to the input terminal of the buzzer 24.
[0067] The specific implementation process is as follows: Through the design of the buzzer 24, when the detector 1 detects a radiation level that exceeds the preset threshold, the buzzer 24 will issue an alarm, thereby taking corresponding measures to handle the situation.
[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation.
