Description

Technical Field

[0001] This invention belongs to the field of nuclear science and technology, and more specifically, relates to a device for predicting the dynamic boundary of radioactive contamination. Background Technology

[0002] A dynamic boundary prediction device for radioactive contamination integrates multi-source data and a diffusion model to achieve its function. Its principle involves collecting data using devices such as a Geiger counter, combining this data with environmental parameters, and then calculating and predicting the contamination boundary using a model. During operation, the Geiger counter serves as the core detection device. Its internal Geiger-Miller counter tube is filled with inert and quenching gases. When radioactive particles enter, they ionize the gas, triggering an electron avalanche under a strong electric field, generating electrical pulses. These pulses are then processed and counted to monitor the radioactive dose rate in the environment in real time. Simultaneously, the device collects environmental data such as wind speed and direction, inputting this information into the diffusion model. This model, coupled with factors such as terrain and meteorology, simulates the diffusion trajectory and dose distribution of radioactive materials. Based on preset thresholds, the contamination boundary is determined and dynamically updated. Finally, the results are output through a visual interface, providing decision support for scenarios such as nuclear emergencies.

[0003] The existing application number is CN201620643781.0. This utility model discloses a nuclear radiation detector with automatic switching detection modes, including a housing with a first detection side, a central processing chip (1) disposed in the housing, and a Geiger counter connected to the central processing chip (1). The first detection side has a first recessed area (2) on its outer side, with multiple windows in the first recessed area. Below the first recessed area is a bearing device (3) and a protective cover (4) fixed to the bearing device. A magnet (5) is fixed to the protective cover. At least one magnetic field detector (6) is fixed to the inner side of the first detection side, and the magnetic field detector (6) is electrically connected to the central processing chip (1). The nuclear radiation detector of this utility model can automatically switch between gamma-ray and alpha / beta-ray detection modes, and can also automatically switch between high and low ranges. It is highly intelligent, easy to operate, and saves manpower.

[0004] Based on the above, when using a Geiger counter to predict the contamination boundary, it is generally necessary to first turn the Geiger counter knob to the circuit self-test switch to perform a self-test. However, in many cases, in order to save time, staff will directly use the Geiger counter for detection, resulting in inaccurate detection results and affecting the accuracy of radioactive contamination boundary prediction. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a dynamic boundary prediction device for radioactive contamination. This addresses the issue that existing methods for predicting contamination boundaries using a Geiger counter typically require rotating the Geiger counter's knob to the circuit self-test switch to perform a self-test. However, often, to save time, staff directly use the Geiger counter for detection, leading to inaccurate detection results and affecting the accuracy of radioactive contamination boundary prediction.

[0006] The purpose and effectiveness of this utility model's dynamic boundary prediction device for radioactive contamination are achieved through the following specific technical means: A device for predicting the dynamic boundary of radioactive contamination includes a Geiger counter body, a control knob, a detector holder, a detector head, a dust cover, a dustproof drive mechanism, and an operation warning mechanism. The control knob is rotatably connected to the top of the Geiger counter body. The detector holder is fixedly connected to the top of the Geiger counter body. The detector head is fixedly connected to the top of the detector holder. The dust cover is rotatably connected to the front end of the detector holder and is positioned at the front end of the detector head. The dustproof drive mechanism is located on the outside of the detector holder. The operation warning mechanism is located above the Geiger counter body.

[0007] Furthermore, the dustproof drive mechanism includes a dustproof drive plate and a dustproof connecting spring; the dustproof drive plate is slidably connected to the lower inner side of the detection and holding frame; multiple sets of dustproof connecting springs are provided, and the multiple sets of dustproof connecting springs are respectively fixedly connected to the upper end of the dustproof drive plate, and the upper ends of the multiple sets of dustproof connecting springs are all fixedly connected to the detection and holding frame.

[0008] Furthermore, the dustproof drive mechanism also includes: a dustproof drive shaft, a dustproof drive gear, and a dustproof drive rack; the dustproof drive shaft is rotatably connected to the front end of the detection and holding frame, and the dustproof drive shaft is coaxially and fixedly connected to the dustproof cover; the dustproof drive gear is coaxially and fixedly connected to the outer rear end of the dustproof drive shaft; the dustproof drive rack is slidably connected to the front end of the detection and holding frame, the dustproof drive rack meshes with the dustproof drive gear, and the rear end of the dustproof drive rack is fixedly connected to the dustproof drive plate.

[0009] Furthermore, the operation warning mechanism includes: a warning drive ring, a warning trigger block, and a warning drive component; the warning drive ring is rotatably connected to the upper part of the Geiger counter body, and the warning drive ring is disposed on the outer periphery of the control knob; the warning trigger block is a magnetic block structure, and the warning trigger block is fixedly connected to the outer periphery of the warning drive ring; the warning drive component is an electromagnet structure, and the warning drive component is fixedly connected to the upper part of the Geiger counter body, the warning drive component is electrically connected to the switching circuit of the Geiger counter body, and the warning drive component is magnetically connected to the warning trigger block.

[0010] Furthermore, the operation warning mechanism also includes a warning reset spring; the warning reset spring is fixedly connected to the rear end of the warning trigger block, and the rear end of the warning reset spring is fixedly connected to the warning drive component.

[0011] Furthermore, the operation warning mechanism also includes: a first warning switch, a second warning switch, a warning squeezing element, and a warning element; the first warning switch is fixedly connected to the rear end of the warning trigger block, and the first warning switch is a push-button switch structure; the second warning switch is fixedly connected to the inner side of the warning drive ring, and the second warning switch is a push-button switch structure, and the second warning switch and the first warning switch together form a double-opening double-control switch structure; the warning squeezing element is fixedly connected to the outer periphery of the control knob; the warning element is an audible and visual alarm, and the warning element is fixedly connected above the warning trigger block, and the first warning switch and the second warning switch are electrically connected to the warning element respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a dustproof drive mechanism. When the operator grips the dustproof drive plate, it is squeezed upwards, causing the dustproof drive rack to move upwards. This upward movement of the dustproof drive rack then rotates the dustproof drive gear, which in turn rotates 180°, causing the dustproof drive shaft to rotate 180°. This 180° rotation of the dustproof drive shaft then rotates the dustproof cover 180°. At this point, the dustproof cover no longer obstructs the probe, allowing it to perform its normal detection function. Once the probe is no longer in use, the dustproof cover resets under the action of the dustproof connecting spring. The dustproof cover effectively shields the probe, preventing external dust and debris from contaminating the probe's detection window. This ensures both the convenience and timeliness of the detection operation and provides long-term protection for the probe, maintaining its detection accuracy and lifespan, thus improving the practicality and reliability of the equipment.

[0013] This invention utilizes an operational warning mechanism. The circuit of the warning drive is connected, generating magnetism. The warning drive attracts a warning trigger block, which moves backward to contact the warning drive. Simultaneously, the backward movement of the trigger block rotates the control knob, causing the warning device to rotate to the self-test position. At this point, the first warning switch is pressed, triggering the warning device to open and emitting an audible and visual warning, prompting the user to turn the control knob to the self-test position. When the user rotates the control knob, it causes the warning squeezing element to rotate, squeezing the second warning switch and closing the warning device. This mechanism effectively reminds workers of the self-test operation of the Geiger counter, preventing omissions, standardizing operating procedures, and ensuring the accuracy of radioactive contamination detection results.

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0021] Example 1: As attached Figures 1 to 4 As shown: This utility model provides a device for predicting the dynamic boundary of radioactive contamination, including a Geiger counter body 1, a control knob 2, a detector holder 3, a detector head 4, a dust cover 5, and a dustproof drive mechanism; the control knob 2 is rotatably connected to the top of the Geiger counter body 1; the detector holder 3 is fixedly connected to the top of the Geiger counter body 1; the detector head 4 is fixedly connected to the top of the detector holder 3; the dust cover 5 is rotatably connected to the front end of the detector holder 3 and is located at the front end of the detector head 4; the dustproof drive mechanism is located on the outside of the detector holder 3.

[0022] The dustproof drive mechanism includes a dustproof drive plate 101 and a dustproof connecting spring 102. The dustproof drive plate 101 is slidably connected to the lower inner side of the detection and holding frame 3. Multiple sets of dustproof connecting springs 102 are provided, and the multiple sets of dustproof connecting springs 102 are respectively fixedly connected to the upper end of the dustproof drive plate 101. The upper ends of the multiple sets of dustproof connecting springs 102 are all fixedly connected to the detection and holding frame 3.

[0023] The dustproof drive mechanism also includes: a dustproof drive shaft 103, a dustproof drive gear 104, and a dustproof drive rack 105; the dustproof drive shaft 103 is rotatably connected to the front end of the probe holder 3, and the dustproof drive shaft 103 is coaxially and fixedly connected to the dustproof cover 5; the dustproof drive gear 104 is coaxially and fixedly connected to the outer rear end of the dustproof drive shaft 103; the dustproof drive rack 105 is slidably connected to the front end of the probe holder 3, the dustproof drive rack 105 meshes with the dustproof drive gear 104, and the rear end of the dustproof drive rack 105 is fixedly connected to the dustproof drive plate 101.

[0024] The specific usage and function of this embodiment are as follows: When the operator performs the detection, the operator's hand grasps the dustproof drive plate 101, which is squeezed upwards. The upward movement of the dustproof drive plate 101 drives the dustproof drive rack 105 upwards, which in turn drives the dustproof drive gear 104 to rotate. The rotation of the dustproof drive gear 104 by 180° drives the dustproof drive shaft 103 to rotate by 180°, which in turn drives the dustproof cover 5 to rotate by 180°. At this time, the dustproof cover 5 no longer blocks the probe head 4, and the probe head 4 can perform detection work normally. Once the probe head 4 is finished using, the dustproof cover 5 returns to its original position under the action of the dustproof connecting spring 102. The dustproof cover 5 effectively blocks the probe head 4, preventing external dust and debris from contaminating the detection window of the probe head 4.

[0025] Example 2: This invention provides a device for predicting the dynamic boundary of radioactive contamination, based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes an operation warning mechanism, which is located above the Geiger counter body 1.

[0026] The operation warning mechanism includes: a warning drive ring 201, a warning trigger block 202, and a warning drive component 203; the warning drive ring 201 is rotatably connected to the top of the Geiger counter body 1, and is located on the outer periphery of the control knob 2; the warning trigger block 202 is a magnetic block structure, and is fixedly connected to the outer periphery of the warning drive ring 201; the warning drive component 203 is an electromagnet structure, and is fixedly connected to the top of the Geiger counter body 1, is electrically connected to the switching circuit of the Geiger counter body 1, and is magnetically connected to the warning trigger block 202.

[0027] The operation warning mechanism also includes a warning reset spring 204; the warning reset spring 204 is fixedly connected to the rear end of the warning trigger block 202, and the rear end of the warning reset spring 204 is fixedly connected to the warning drive component 203.

[0028] The operation warning mechanism also includes: a first warning switch 205, a second warning switch 206, a warning squeeze member 207, and a warning member 208; the first warning switch 205 is fixedly connected to the rear end of the warning trigger block 202, and the first warning switch 205 is a push-button switch structure; the second warning switch 206 is fixedly connected to the inner side of the warning drive ring 201, and the second warning switch 206 is a push-button switch structure, and the second warning switch 206 and the first warning switch 205 together form a double-opening double-control switch structure; the warning squeeze member 207 is fixedly connected to the outer periphery of the control knob 2; the warning member 208 is an audible and visual alarm, and the warning member 208 is fixedly connected above the warning trigger block 202, and the first warning switch 205 and the second warning switch 206 are electrically connected to the warning member 208 respectively.

[0029] The specific usage and function of this embodiment are as follows: When the user turns on the power of the Geiger counter body 1, the circuit of the warning drive 203 is connected, and the warning drive 203 generates magnetism. The warning drive 203 attracts the warning trigger block 202 backward, and the warning trigger block 202 moves backward to contact the warning drive 203. At the same time, the rearward movement of the warning trigger block 202 drives the control knob 2 to rotate. The rotation of the control knob 2 drives the warning element 208 to the self-test position. At this time, the first warning switch 205 is squeezed, triggering the warning element 208 to open. The warning element 208 emits an audible and visual warning, prompting the user to turn the control knob 2 to the self-test position for self-test. When the user rotates the control knob 2, the rotation of the control knob 2 drives the warning squeeze element 207 to rotate. The rotation of the warning squeeze element 207 squeezes the second warning switch 206. The second warning switch 206 is squeezed and closes the warning element 208. This realizes the reminder of the Geiger counter self-test operation, avoids workers from missing operations, standardizes the workers' operating procedures, and ensures the accuracy of the radioactive contamination detection results.
