Description

Technical Field

[0001] The invention relates to the technical field of radiation shielding performance detection, and in particular to a shielding performance detection device for a radiation protection structure. Background Art

[0002] Radiation protection structures are structural systems designed and constructed to reduce or prevent the harm of radiation to the human body and the environment. This structural system is widely used in many fields, including nuclear energy, medical treatment, scientific research and other industries involving radioactive materials or radiation sources. The main materials of radiation protection structures include materials with high density and good radiation absorption characteristics. Shielding performance testing is an important means to evaluate the ability of radiation protection structures to block electromagnetic waves or radiation. Through testing, we can understand the shielding effectiveness of the protection structure under different frequencies and different intensities of radiation, so as to ensure its protection effect in practical applications.

[0003] In the prior art, announcement number CN114486945B discloses a detection device for the shielding performance of radiation protection materials and a test method thereof, including a detection platform and an irradiation platform. The detection platform is fixedly or movably installed above the irradiation platform. The detection platform includes a detection fixing structure and a detector. The detection fixing structure is used to fix the detector. The irradiation platform includes an irradiation fixing structure, an irradiation source and a sample card slot. The irradiation fixing structure is used to fix the irradiation source. The sample to be tested is fixed above the irradiation source through the sample card slot. This patent fixes the position of the detector and replaces the sample above during detection, thereby ensuring that the sample can completely cover the radiation source each time it is placed, and the axes of the radiation source, sample and detector coincide in the vertical direction, thereby improving the stability of the test device and the test stability.

[0004] During use, it is often necessary to test several samples and take the average value to obtain the average qualified rate or other qualified values ​​of the batch of products. In the process of replacing samples one by one, the operator needs to constantly open the sample card slot, fix the samples to be tested, and then test them one by one. When the number of samples is large, replacing and testing one by one will significantly extend the test cycle. In the process of opening the sample card slot and replacing the samples, the operator may be exposed to potential radiation environment, increasing the risk of radiation damage. Frequent operation may increase the possibility of operating errors, such as unstable sample fixation, card slot damage, etc., which will affect the accuracy of the test results.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0035] Please refer to Figures 1 to 9 , a shielding performance detection device for a radiation protection structure, comprising: a detection platform 1, a conveyor belt 2 is connected to the inner cavity of the detection platform 1 by transmission, the conveyor belt 2 is provided with a notch 1 5 and a notch 2 17, a detector 3 is fixedly arranged in the conveyor belt 2, and an irradiator 4 is fixedly arranged above the conveyor belt 2 and located at the top of the inner cavity of the detection platform 1. The detection platform 1 is the basis of the entire detection device, and the detection platform 1 provides installation and operation space for components such as the conveyor belt 2, the detector 3 and the irradiator 4. The conveyor belt 2 is arranged in the inner cavity of the detection platform 1 and is connected by transmission to realize continuous transportation of samples. The detector 3 is fixedly arranged in the conveyor belt 2 and is used to perform shielding performance detection on the samples passing through.

The irradiator 4 is fixedly arranged above the conveyor belt 2 and located at the top of the inner cavity of the detection platform 1. It is used to emit radiation to the sample to simulate the radiation conditions in the actual use environment and evaluate the shielding performance of the sample.

[0036] Please refer to Figures 1 to 9, a radiation protection structure shielding performance detection device, further comprising: a detection platform 1 is provided with a conveying mechanism in the inner cavity, the conveying mechanism comprises a rotating shaft 6 rotatably arranged on the detection platform 1, a fixed disk 7 is fixedly arranged on the top of the rotating shaft 6 above the notch 5, a plurality of baffles 8 are fixedly arranged on the fixed disk 7, and the baffles 8 are arranged in a circle with the axis of the fixed disk 7 as the origin, and the conveying mechanism is used to intermittently convey the workpiece to be detected above the conveyor belt 2; through the synergistic effect of the conveyor belt 2 and the conveying mechanism, the workpiece to be detected can be automatically conveyed and accurately positioned at the detection position. When the workpiece stays at the detection position, the detector 3 will perform a shielding performance test on it. The detector 3 may use a variety of technical principles to measure the shielding effect of the workpiece on radiation. The irradiator 4 emits radiation to the workpiece to simulate the radiation conditions in the actual use environment.

At the same time, through accurate shielding performance detection and irradiation simulation evaluation, the reliability and safety of the workpiece in actual application can be ensured.

[0037] Please refer to Figures 1 to 9 , a radiation protection structure shielding performance detection device, further comprising: a stacking mechanism is provided at the end of the conveyor belt 2, the stacking mechanism comprises a C-shaped frame 31 provided at the end of the conveyor belt 2, a fixed shaft 32 is symmetrically and equidistantly fixed on the C-shaped frame 31, a rotating block 33 is rotatably provided on the fixed shaft 32, and a limiting column 34 for limiting is fixedly provided on the upper surface of the rotating block 33, and the stacking mechanism is used to stack the workpieces that have been inspected in sequence.

After the workpieces are inspected, they can be automatically transported to the stacking mechanism for stacking, which reduces the time and error of manual operation. Stacking the workpieces in sequence by the stacking mechanism can save storage space and improve space utilization. And through the records of the detection device system, defective products can be quickly eliminated. When a workpiece is detected to be unqualified, the system can immediately mark the workpiece serial number so that it can be quickly identified and processed when all workpieces are taken out from the stacking mechanism later. This helps to reduce the outflow of defective products and improve the overall product quality.

[0038] Please refer to Figures 1 to 6Furthermore, the conveying mechanism also includes a fixed block 9 sleeved on the rotating shaft 6, and the outer surface of the fixed block 9 is fixedly arranged on the side wall of the conveyor belt 2. A synchronous disk 10 is also fixedly arranged on the outer surface of the rotating shaft 6, and a plurality of slots 11 are arranged on the synchronous disk 10, and the slots 11 are arranged in a circle with the axis of the synchronous disk 10 as the origin. The synchronous disk 10 is located below the fixed block 9, and a connecting block 12 is fixedly arranged on the outer surface of the fixed block 9, and a tension spring 13 is sleeved on the connecting block 12. The tension of the tension spring 13 is less than the conveying force of the conveyor belt 2. A support 14 is fixedly arranged on the side of the detection platform 1 close to the notch 15, and a clamping rod 16 is rotatably connected to the support 14, and the sharp end of the clamping rod 16 is located in the clamping groove 11. A connecting block 2 15 is fixedly arranged on the clamping rod 16, and the connecting block 2 15 and the end of the tension spring 13 away from the connecting block 12 are sleeved on each other.

[0039] The workpiece to be inspected is limited by the stop rod 8, and then the irradiator 4 emits radiation to the workpiece to simulate the radiation conditions in the actual use environment, and then the detector 3 performs detection and analysis. The workpiece to be inspected is transported one by one in order to the bottom of the detector 3 for detection and processing, and the performance of the workpiece is evaluated by measuring the shielding effect of the workpiece after being irradiated by the detector 3. This method has the advantages of being intuitive, accurate and repeatable. The entire detection process can be automated, reducing human intervention and errors. Accurate shielding performance data can be obtained through precise irradiation and detection methods. During the detection process, both the irradiator 4 and the detector 3 adopt safety protection measures, and do not require excessive human intervention, thereby ensuring the safety of the operator.

[0040] For details, please refer to Figure 1 to Figure 2 as well as Figures 7 and 8 A support 2 18 is fixedly provided on one side of the detection platform 1 near the second notch 17, and a rotating rod 19 is rotatably connected to the support 2 18. The end of the rotating rod 19 away from the support 2 18 is located above the second notch 17 and extends to the conveyor belt 2. A fixed rod 20 is fixedly provided at the bottom of the rotating rod 19, and a connecting rod 21 is rotatably connected to the outer surface of the fixed rod 20. The end of the connecting rod 21 away from the fixed rod 20 is rotatably connected to the top of the clamping rod 16. A sliding groove 22 is provided on the second notch 17, and a limiting rod 23 is fixedly provided in the sliding groove 22.

[0041] The workpiece inspected by the conveyor belt 2 squeezes the rotating rod 19, which in turn causes the rotating rod 19 to rotate and pulls the tension spring 13 through the fixed rod 20, so that the next workpiece to be inspected is within the irradiation inspection range, thereby realizing the automated process of workpiece inspection. When the workpiece is inspected, the next workpiece can be automatically pushed into the inspection area without manual operation, thereby improving the inspection efficiency. The automatic transfer of workpieces is achieved through the mechanical structure, which reduces the need for manual handling and placement of workpieces, thereby saving labor costs. The automated process helps to ensure that each workpiece can be inspected in the same manner and under the same conditions, reduces the inspection errors caused by human factors, and improves the accuracy of the inspection. The design of the mechanical structure is usually more stable and reliable than manual operation. Through the synergistic effect of components such as the rotating rod 19, the fixed rod 20 and the tension spring 13, the stability and consistency of the workpiece during the inspection process can be ensured. The design has modular characteristics and is easy to expand or adjust according to actual needs. At the same time, the maintenance of the mechanical structure is relatively simple, reducing maintenance costs and time.

[0042] For details, please refer to Figures 7 and 8 , a spring 24 is sleeved on the outer surface of the limit rod 23, wherein the elastic force of the spring 24 is less than the conveying force of the conveyor belt 2 to convey the workpiece. A slider 25 is slidably connected to the end of the limit rod 23 close to the rotating rod 19, and a contact 1 26 is fixedly provided on the slider 25, and a contact 2 27 is fixedly provided on the side wall of the notch 2 17, and the contact 1 26 and the contact 2 27 are electrically connected to each other. The slider 25 is squeezed by rotating the rotating rod 19 to compress the spring 24, so that the contact 1 26 and the contact 2 27 are close to each other and electrically connected. Automatic control can be achieved through the electrical connection between the contact 1 26 and the contact 2 27. When the workpiece pushes the slider 25 and causes the contact 1 26 and the contact 2 27 to contact, an electrical signal can be triggered to control the next operation of the equipment.

[0043] For further information, please refer to Figures 2 to 4 , Figure 7 as well as Fig. 9 The stacking mechanism also includes a connecting plate 28 fixedly arranged at the bottom of the C-shaped frame 31, and a through slot 29 is formed through the connecting plate 28, and a top plate 30 is slidably arranged in the through slot 29. A push cylinder is arranged at the bottom of the top plate 30 on the detection platform 1, and the output shaft of the push cylinder is fixedly connected to the top plate 30. The push cylinder controls the opening and closing of the top plate 30 by moving away from or close to the contact 1 26 and the contact 2 27.

[0044] By pushing the telescopic movement of the cylinder, the top plate 30 can automatically move up and down, thereby realizing automatic stacking of workpieces. This greatly improves the stacking efficiency and reduces manual intervention. The setting of contact 1 26 and contact 2 27 allows the opening and closing of the push cylinder to be precisely controlled. This ensures the stability and accuracy of the top plate 30 during the stacking process. The design of the C-shaped frame 31 and the connecting plate 28 makes the entire stacking mechanism compact and occupies less space. This helps to save equipment costs and improve space utilization. Since the connections between components are relatively simple and intuitive, the design is easy to maintain and inspect. Once a fault occurs or maintenance is required, the problem can be quickly located and repaired. The stacking mechanism can quickly stack workpieces in sequence, supports data tracking, and facilitates operators to quickly find defective products, thereby ensuring the overall quality of the product.

[0045] Through all the above embodiments, the working principle of the present invention is specifically as follows:

[0046] Before starting, the workpiece to be tested is placed on the conveyor belt 2 between the blocking bars 8, and then a spare sample (not required to be tested) is placed on the conveyor belt 2 on the side of the workpiece to be tested close to the C-shaped frame 31.

[0047] Start the equipment, and the conveyor belt 2 starts to rotate. Under the restriction of the baffle rod 8, the synchronous disk 10 and the clamp rod 16, the sample to be detected will continue to stay on the conveyor belt 2 for a period of time. When the spare sample on the conveyor belt 2 squeezes the rotating rod 19, it will cause the rotating rod 19 to rotate around the support 18 to the side of the slide groove 22, so that the fixed rod 20 pulls the clamp rod 16 through the tension spring 13, causing the sharp end of the clamp rod 16 to disengage from the clamp groove 11. At this time, the detection of the workpiece to be detected on the conveyor belt 2 is completed, and the transmission of the conveyor belt 2 causes the baffle rod 8 to drive the rotating shaft 6 to rotate. The next workpiece to be detected is stuck in the detection area, and the baffle rod 8 limits the workpiece to be detected. Then, the irradiator 4 emits radiation to the workpiece to simulate the radiation conditions in the actual use environment, and then the detector 3 performs detection and analysis. The workpiece to be detected is transported one by one to the bottom of the detector 3 for detection and processing, and the shielding effect of the workpiece after being irradiated is measured by the detector 3 to evaluate its performance. This method has the advantages of being intuitive, accurate and repeatable. The entire detection process can be automated, reducing manual intervention and errors. Accurate shielding performance data can be obtained through precise irradiation and detection methods. During the detection process, both the irradiator 4 and the detector 3 adopt safety protection measures, and do not require excessive human intervention, thereby ensuring the safety of the operator;

[0048] At the same time, contact 1 26 approaches contact 2 27 and fits closely with contact 2 27 under the push of rotating rod 19. After fitting, contact 1 26 is electrically connected to contact 2 27, and the cylinder is prompted to extend and retract once. At this time, the workpiece that has been inspected and transported by conveyor belt 2 is located on the docking platform and is lifted up by top plate 30. During the lifting process, rotating block 33 rotates along fixed axis 32. When the cylinder returns, under the influence of gravity, the workpiece that has been inspected falls smoothly on rotating block 33 and is limited by limit column 34 to prevent the workpiece from falling off. In this way, the workpiece that has been inspected is stacked on rotating block 33 in an orderly manner. By pushing the telescopic movement of the cylinder, top plate 30 can automatically move up and down, thereby realizing automatic stacking of workpieces. This greatly improves the stacking efficiency and reduces manual intervention. The setting of contact 1 26 and contact 2 27 enables the opening and closing of the push cylinder to be accurately controlled. This ensures the stability and accuracy of top plate 30 during the stacking process. The design of the C-shaped frame 31 and the docking plate 28 makes the entire stacking mechanism compact and occupies less space. This helps save equipment costs and improve space utilization. Since the connections between components are relatively simple and intuitive, the design is easy to maintain and inspect. Once a failure occurs or maintenance is required, the problem can be quickly located and repaired. The stacking mechanism can quickly stack workpieces in sequence, supports data tracking, and facilitates operators to quickly find defective products, thereby ensuring the overall quality of the product.

[0049] A person skilled in the art should understand that the discussion of any of the above embodiments is only exemplary, and within the spirit of the present invention, the technical features in the above embodiments or in different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
