Description

Technical Field

[0001] This utility model relates to the field of nuclear radiation detection equipment, and in particular to a portable nuclear radiation detector. Background Technology

[0002] Nuclear radiation detection plays an irreplaceable role in environmental monitoring, industrial production, emergency rescue, and routine safety inspections. In particular, in scenarios such as the vicinity of nuclear facilities, suspected radioactive contamination areas, and nuclear industry pipeline inspections, portable detection equipment is needed to achieve flexible and rapid radiation data collection.

[0003] Existing detectors can only detect radiation within a fixed range. They cannot accurately detect radiation at high points, in pipes, or in gaps. During continuous monitoring, detection is carried out manually by hand or by simply placing the device on the ground. This not only exposes people to radiation for extended periods, but also makes the device prone to displacement due to external factors, affecting the accuracy of the data. Utility Model Content

The extension length is further increased by the rotation of the folding plate, making the detection equipment convenient for detecting narrow gaps or pipes at height. With the detachable magnetic base at the bottom, it can be fixed to a metal surface for continuous detection.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides a portable nuclear radiation detector, comprising a body 1, a folding plate 2 rotatably connected to the inner wall of the body 1, a telescopic block 3 slidably connected to the inner wall of the folding plate 2, a spring 15 fixedly connected to the inner wall of the telescopic block 3, a fixing pin 16 slidably connected to the inner wall of the telescopic block 3, a detection head 4 fixedly connected to the inner wall of the telescopic block 3, a magnetic suction seat 5 slidably connected to the bottom of the body 1, a first bolt 6 threadedly connected to the inner wall of the body 1, a connecting seat 7 slidably connected to the inner wall of the magnetic suction seat 5, a fixing seat 8 slidably connected to the lower surface of the connecting seat 7, an adjusting bracket 9 rotatably connected to the bottom end of the fixing seat 8, a second bolt 10 threadedly connected to the inner wall of the adjusting bracket 9, a telescopic bracket 11 slidably connected to the inner wall of the adjusting bracket 9, and a protective component provided on the outer wall of the body 1.

[0024] Specifically, the telescopic block 3 slides on the inner wall of the folding plate 2, and the extension length is locked by the cooperation of the spring 15 and the fixing pin 16. With the rotation of the folding plate 2, the detection distance is further extended, which can easily penetrate into narrow gaps and reach high pipes to complete nuclear radiation detection, directly hitting the detection position and solving the problem of inaccurate detection results caused by the limited detection range of traditional equipment. The detachable magnetic base 5 at the bottom can be quickly fixed to the metal surface, meeting the stable and continuous detection requirements of the equipment on the metal carrier. The adjustment bracket 9 at the bottom of the magnetic base 5 and the telescopic bracket 11 can be flexibly adapted to adjust the support height and shape according to different ground flatness, ensuring that the equipment can be placed stably on uneven and non-flat ground. At the same time, the sliding connection structure of the connecting seat 7 and the fixing seat 8 supports multi-angle adjustment, allowing the detection head 4 to be adjusted as needed to adapt to complex detection scenarios and greatly expand the applicable environment of the equipment. Whether in narrow spaces, high positions, metal surfaces, or various ground surfaces, stable and accurate continuous nuclear radiation detection can be achieved, improving detection efficiency and data reliability.

[0025] Reference Figures 1-4 The protective component includes a slider 17, with both ends of the slider 17 slidably connected to the inner wall of the body 1. A protective plate 12 is rotatably connected to the outer surface of the slider 17. A connecting rope 13 is fixedly connected to the outer wall of the protective plate 12. A protective cover 14 is fixedly connected to one end of the connecting rope 13.

[0026] Specifically, the slider 17 slides along the slide rail of the machine body 1 to control the opening and closing of the protection plate 12. When idle, the closed protection plate 12 can cover the surface of the machine body 1 to prevent the main body of the equipment from being damaged by external collisions and friction. At the same time, the protective cover 14 can be inserted into the inner wall of the telescopic block 3 to cover the detection head 4, preventing the detection head 4 from becoming less sensitive due to dust accumulation or accidental bumps during carrying or storage. When continuously testing outdoors, the protection plate 12 can build an effective protective barrier for the main body of the equipment, blocking wind and sand invasion and rain splashes, and avoiding the impact of harsh environments on the stability of equipment operation.

[0027] Reference Figures 1-3 The inner wall of the folding plate 2 is provided with multiple pin grooves. One end of the fixing pin 16 is slidably connected to the inner wall of the pin groove. The surface of the telescopic block 3 is provided with a limit groove, and the inner wall of the folding plate 2 is provided with a limit block.

[0028] Specifically, the limiting groove, together with the limiting block, restricts the maximum extension distance of the telescopic block 3, and the fixing pin 16 fixes the extension length, so that the detection head 4 can accurately reach the vicinity of the detection position, making the detection results more accurate.

[0029] Reference Figure 2 The upper surface of the connector 7 is provided with a triangular protrusion, and the lower surface of the magnetic seat 5 is provided with a triangular slot.

[0030] Specifically, precise locking prevents the detector from shifting position during testing due to loose connections, thus ensuring testing stability.

[0031] Reference Figure 2 The bottom of the connecting seat 7 is provided with a sliding rod, and the inner wall of the fixing seat 8 is slidably connected to the outer wall of the sliding rod. The lower surface of the connecting seat 7 is provided with anti-slip texture, and the upper surface of the fixing seat 8 is provided with anti-slip texture.

[0032] Specifically, when the angle needs to be adjusted, lift the connecting seat 7, rotate it to the required angle, and then lower it. The angle will be fixed by the anti-slip texture and the weight of the detector itself, making the angle adjustment quick and convenient.

[0033] Reference Figure 2 The bottom end of the second bolt 10 is slidably connected to the surface of the telescopic bracket 11. A limit groove is opened on the surface of the telescopic bracket 11, and a limit block is provided on the inner wall of the adjusting bracket 9.

[0034] Specifically, the limiting slide groove works in conjunction with the telescopic bracket 11 to limit the maximum distance the telescopic bracket 11 slides out, and the second bolt 10 fixes the extension length of the telescopic bracket 11, so that the equipment can be placed stably on different ground surfaces.

[0035] Reference Figure 4 The outer wall of the body 1 is provided with a slide rail, and the two ends of the slider 17 are slidably connected in the slide rail.

[0036] Specifically, slider 17 flexibly adjusts the position of the protection component, and the slide rail restricts the movement trajectory of slider 17, thereby improving the stability and convenience of using the protection component.

[0037] Working principle: When using this device, the protective plate 12 can be opened directly for operation. When the detection scenario requires the device to be extended, the telescopic block 3 is pulled to slide along the inner wall of the folding plate 2. The spring 15 inside the telescopic block 3 pushes the fixing pin 16 into the pin groove on the inner wall of the folding plate 2, fixing the extension length of the telescopic block 3, so that the detection head 4 inside the telescopic block 3 reaches the detection position. When the maximum extension length is insufficient, the folding plate 2 is rotated to further increase the length. When continuous detection is required, the fixing method can be selected according to the usage scenario. The magnetic seat 5 is fixed to the body 1 by the first bolt 6 and can be adsorbed on the surface of the metal carrier for detection. When it is necessary to place it on the ground for detection, the connecting seat 7 is engaged with the magnetic seat 5, the second bolt 10 is loosened to allow the telescopic bracket 11 to slide out, and then the second bolt 10 is tightened. The adjusting bracket 9 is rotated to initially fix the device on the ground. Finally, the second bolt 10 is turned to adjust the extension length of the telescopic bracket 11 so that the device is level with the ground for detection.

[0038] In the non-detection state, the sliding slider 17 moves along the slide rail on the outer wall of the machine body 1, causing the protective plate 12 to close and cover the machine body 1. At the same time, the protective cover 14 is inserted into the inner wall of the telescopic block 3 to cover the detection head 4. If protection is required during continuous detection, the protective plate 12 is slid to cover the upper surface of the machine body 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
