Description

A positioning device for radiation detection instruments Technical Field

[0001] This utility model relates to the field of radiation detection equipment technology, and in particular to an auxiliary positioning device for radiation detection instruments. Background Technology

[0002] Radiation detection instruments are devices used to detect and measure ionizing radiation (such as alpha particles, beta particles, gamma rays, and neutron rays). These instruments are widely used in nuclear physics, environmental monitoring, medicine, and industrial safety to assess radiation levels, ensure personnel safety, and protect the environment. Radiation detection instruments typically include detectors (such as Geiger-Müller counters, scintillation detectors, and semiconductor detectors), signal processing units, display devices, and data storage / transmission units. The detector converts the received radiation into electrical signals, the signal processing unit amplifies, analyzes, and processes these signals, and the display device ultimately presents the radiation dose or intensity in numerical, graphical, or auditory form. Some advanced radiation detection instruments also feature data logging, wireless transmission, and alarm functions, enabling real-time monitoring of environmental radiation changes and issuing alarms when preset safety thresholds are exceeded, providing users with timely and effective radiation protection information.

[0003] In the field of radiation detection, existing instruments are usually fixed in place, meaning they are used for radiation monitoring at a specific location. This fixed installation method can meet basic monitoring needs in simple or known environments. However, when faced with complex environments and the need for multi-angle detection to accurately determine the location and intensity of radiation sources, existing technologies fall short. To compensate for this deficiency, multiple radiation detectors are often installed and fixed in different locations. However, this approach not only significantly increases equipment costs and maintenance burdens, but also makes it difficult to accurately align the radiation source under test in complex environments because each detector remains stationary. This results in significant deviations in the detection results and fails to meet the requirements of applications with high accuracy. Summary of the Invention

[0004] One objective of this invention is to provide an instrument-assisted positioning device for radiation detection. This invention addresses the problem mentioned in the background that existing instruments in the field of radiation detection typically employ fixed installation, meaning they monitor radiation at a specific location. While this fixed installation method can meet basic monitoring needs in simple or known environments, it falls short when facing complex environments requiring multi-angle detection to accurately determine the location and intensity of radiation sources. To compensate for this deficiency, multiple radiation detectors are often installed and fixed in different locations. However, this approach significantly increases equipment costs and maintenance burdens. Furthermore, because each detector remains stationary, it is difficult to achieve precise alignment with the radiation source under test in complex environments, leading to significant deviations in the detection results and failing to meet the requirements of applications with high accuracy demands.

[0005] A radiation detection instrument-assisted positioning device according to an embodiment of the present invention includes:

[0006] A multi-angle adjustment mechanism includes a mounting plate installed on a telescopic mechanism. A fixed arm is fixedly installed at the bottom of the mounting plate, and a movable arm is rotatably installed at the lower end of the fixed arm. The movable arm is connected to the mounting plate through a first drive assembly to achieve vertical angle adjustment. A positioning frame is rotatably installed at the lower end of one side of the movable arm through a T-shaped pivot. The positioning frame is connected to the movable arm through a second drive assembly to achieve horizontal angle adjustment. A radiation detector is installed inside the positioning frame through a locking assembly.

[0007] The telescopic mechanism, installed on one side of the multi-angle adjustment mechanism, is used to adjust the distance between the detector and the radiation source.

[0008] Preferably, the first drive assembly includes a first forward and reverse motor fixed to one side of the mounting plate, a first screw fixedly disposed at the output end of the first forward and reverse motor, a first moving block being threadedly disposed on the outer side of the first screw, and a connecting rod being rotatably disposed between the first moving block and the movable arm.

[0009] Preferably, the second drive assembly includes a second forward and reverse motor fixed to the top of the movable arm, a second screw fixedly disposed at the output end of the second forward and reverse motor, a second movable seat disposed on the outer thread of the second screw, and a lever fixedly disposed between the second movable seat and the positioning frame.

[0010] Preferably, the locking assembly includes an L-shaped locking member that rotates on both sides of the positioning frame. The bent end of the L-shaped locking member passes through the interior of the positioning frame and engages with the radiation detector. A spring is fixedly provided between the pressing end of the L-shaped locking member and the positioning frame.

[0011] Preferably, the bent end of the L-shaped lock is a wedge-shaped structure.

[0012] Preferably, the telescopic mechanism includes a positioning post, an L-shaped telescopic arm is movably disposed on the top of the positioning post, the outer sides of the L-shaped telescopic arm and the positioning post are respectively provided with corresponding first positioning holes and first elastic locking pins, and a second telescopic arm is movably disposed at the front end of the L-shaped telescopic arm, the outer sides of the second telescopic arm and the L-shaped telescopic arm are respectively provided with corresponding second positioning holes and second elastic locking pins.

[0013] Preferably, there are multiple first positioning holes and second positioning holes, and the first positioning hole and the first elastic locking pin are engaged, as are the second positioning hole and the second elastic locking pin.

[0014] Preferably, the mounting plate is fixed to the bottom of the second telescopic arm.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the problem of traditional fixed radiation detectors requiring multiple devices due to their inability to adjust multiple angles, thanks to its multi-angle adjustment mechanism. During use, the spring in the locking assembly continuously presses the pressing end of the L-shaped locking piece, causing the wedge-shaped bent end to tightly engage with the groove of the radiation detector. This ensures stable installation and facilitates quick assembly and disassembly. When adjusting the detector's pitch angle, the first forward and reverse motor drives the first screw to rotate, causing the first moving block to move along the screw's axial direction. This, in turn, pushes the movable arm to swing up and down around the hinge point of the fixed arm via a connecting rod, achieving vertical angle adjustment of the radiation detector. When horizontal adjustment is needed, the second forward and reverse motor drives the second screw to rotate, causing the second moving seat to drive the lever to rotate the positioning frame left and right around the T-shaped axis, thus achieving precise horizontal angle adjustment.

[0017] This invention effectively avoids the problem of radiation intensity detection error caused by a fixed distance by setting a telescopic mechanism. In use, by stretching the L-shaped telescopic arm and moving it up and down along the positioning post, when the first elastic pin pops into the corresponding first positioning hole, the height of the radiation detector can be adjusted. Then, by pulling out the second telescopic arm, the distance between the radiation detector and the radiation source can be adjusted by the engagement of the second elastic pin with the second positioning hole. Thus, flexible and accurate detection of the radiation source can be achieved in complex environments. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Referring to Figures 1-4, an instrument-aided positioning device for radiation detection includes:

[0026] The multi-angle adjustment mechanism 1 includes a mounting plate 101 mounted on a telescopic mechanism 2. A fixed arm 102 is fixedly mounted at the bottom of the mounting plate 101, and a movable arm 103 is rotatably mounted at the lower end of the fixed arm 102. The movable arm 103 is connected to the mounting plate 101 via a first drive assembly to achieve vertical angle adjustment. The first drive assembly includes a first forward / reverse motor 104 fixed to one side of the mounting plate 101. A first screw 105 is fixedly mounted at the output end of the first forward / reverse motor 104. A first moving block 106 is threadedly driven on the outer side of the first screw 105. A connecting rod 107 is rotatably mounted between the first moving block 106 and the movable arm 103. A positioning frame 108 is rotatably mounted at the lower end of one side of the movable arm 103 via a T-shaped pivot 109. The positioning frame 108 is connected to the movable arm 103 via a second drive assembly to achieve horizontal angle adjustment. The second drive assembly includes a second drive assembly fixed to the top of the movable arm 103. The first positive and negative motor 110 has a second screw 111 fixedly installed at its output end. A second movable seat 112 is threaded on the outer side of the second screw 111. A lever 113 is fixedly installed between the second movable seat 112 and the positioning frame 108. A radiation detector 116 is installed inside the positioning frame 108 through a locking assembly. When it is necessary to adjust the pitch angle of the detector, the first positive and negative motor 104 drives the first screw 105 to rotate, which drives the first movable block 106 to move along the screw axis. Through the connecting rod 107, the movable arm 103 is pushed to swing up and down around the hinge point of the fixed arm 102, thereby realizing the vertical angle adjustment of the radiation detector 116. When it is necessary to adjust the horizontal direction, the second positive and negative motor 110 drives the second screw 111 to rotate, which causes the second movable seat 112 to drive the lever 113 to push the positioning frame 108 to deflect left and right around the T-shaped rotating shaft 109, thereby realizing the precise adjustment of the horizontal angle.

[0027] Telescopic mechanism 2, installed on one side of multi-angle adjustment mechanism 1, is used to adjust the distance between the detector and the radiation source. Telescopic mechanism 2 includes a positioning post 201, an L-shaped telescopic arm 203 movably mounted on the top of the positioning post 201, and corresponding first positioning holes 204 and first elastic latches 205 on the outer sides of the L-shaped telescopic arm 203 and the positioning post 201, respectively. A second telescopic arm 206 movably mounted at the front end of the L-shaped telescopic arm 203, and corresponding second positioning holes 207 and second elastic latches 208 on the outer sides of the second telescopic arm 206 and the L-shaped telescopic arm 203, respectively. By stretching the L-shaped telescopic arm to move up and down along the positioning post, when the first elastic latch springs into the corresponding first positioning hole, the height of the radiation detector can be adjusted. Then, by pulling out the second telescopic arm, the distance between the radiation detector and the radiation source can be adjusted through the engagement of the second elastic latch with the second positioning hole.

[0028] Example 1: The locking assembly includes an L-shaped locking member 114 that rotates on both sides of the positioning frame 108. The bent end of the L-shaped locking member 114 passes through the interior of the positioning frame 108 and engages with the radiation detector 116. A spring 115 is fixedly provided between the pressing end of the L-shaped locking member 114 and the positioning frame 108. The bent end of the L-shaped locking member 114 has a wedge-shaped structure. In the locking assembly, the spring 115 continuously presses the pressing end of the L-shaped locking member 114, so that the wedge-shaped bent end is tightly engaged in the groove of the radiation detector 116, which ensures the stable installation of the instrument and facilitates quick assembly and disassembly.

[0029] Example 2: Several first positioning holes 204 and second positioning holes 207 are provided. The first positioning hole 204 and the first elastic locking pin 205 are engaged, and the second positioning hole 207 and the second elastic locking pin 208 are engaged. The mounting plate 101 is fixed to the bottom of the second telescopic arm 206. By manually adjusting the telescopic arm and engaging the elastic locking pins into the corresponding positioning holes, the distance between the detector and the radiation source can be graded and adjustable. The operation is simple and the positioning is accurate. It can effectively avoid the problem of inaccurate detection caused by the fixed distance between the detector and the radiation source, and realize flexible and accurate detection of the radiation source in complex environments.

[0030] Working principle: First, the distance between the detector and the radiation source is adjusted by the telescopic mechanism 2. An L-shaped telescopic arm 203 is movably installed on the top of the positioning post 201. By stretching the L-shaped telescopic arm, it moves up and down along the positioning post. When the first elastic locking pin 205 springs into the corresponding first positioning hole 204, the height adjustment is completed. Then, the second telescopic arm 206 is pulled out, and the distance is adjusted by the engagement of the second elastic locking pin 208 with the second positioning hole 207. Next, the angle of the detector is adjusted by the multi-angle adjustment mechanism 1. A fixed arm 102 is fixed at the bottom of the mounting plate 101, and a movable arm 103 is rotatably installed at its lower end. The first drive assembly, including the first forward and reverse motor 104, the first screw 105, and the first moving block 106, drives the detector to move. The movable arm 103 swings up and down around the hinge point of the fixed arm 102 to adjust the vertical angle of the radiation detector 116. At the same time, the positioning frame 108 adjusts the left and right angles through the second drive assembly, including the second forward and reverse motor 110, the second screw 111, and the second moving seat 112. The second moving seat 112 drives the lever 113 to push the positioning frame 108 to deflect left and right around the T-shaped rotating shaft 109, thereby achieving precise adjustment of the horizontal angle. Finally, the locking assembly ensures that the radiation detector 116 is securely installed. The bent end of the L-shaped lock 114 has a wedge-shaped structure. The spring 115 presses the pressing end of the L-shaped lock 114, so that the wedge-shaped bent end is tightly locked into the groove of the radiation detector 116, which not only ensures the stable installation of the instrument but also facilitates quick disassembly and assembly.
