Description

Technical Field

[0001] This utility model relates to the field of detection equipment technology, and in particular to a dual-purpose β-γ radiation simultaneous detection device. Background Technology

[0002] In radioactive environments such as nuclear industry and nuclear physics laboratories, it is often necessary to measure the β and γ spectra of samples or environments for quantitative analysis of activity, energy spectra, and dose rates. Existing detection devices are broadly classified into two types:

[0003] One type is a desktop detection device, such as the online total radiation dose detection device disclosed in patent CN218647156U. When in use, the radiation source is placed above the irradiation cavity, and the optical fiber is placed in the irradiation cavity with the ability to attenuate radiation, so that the radiation dose absorbed by the optical fiber is less than the boundary condition. At this time, the power loss of the optical fiber is linearly related to the radiation dose. Based on this, the environmental dose is characterized by real-time detection of the power of the optical fiber.

[0004] Another type is a mobile detection device, such as a portable nuclear radiation detector disclosed in patent CN221883909U. When in use, the staff holds a telescopic rod, brings the probe close to the radiation source to be detected, and feeds back the detection signal to the detector body.

[0005] The two detection methods described above correspond to two different scenarios, but currently no radiation source detection device can combine these two methods, resulting in limited versatility. Therefore, this application proposes a dual-purpose β-γ radiation simultaneous detection device to cover more application scenarios, thereby improving the device's versatility. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention provides a dual-purpose β-γ radiation simultaneous detection device. The probe can be selectively installed in either a first or second mounting position. When the probe is in the first mounting position, it works with a detection platform to detect radioactive samples placed on the platform, making it suitable for small samples that are easy to place on a platform. When the probe is installed in the second mounting position on a telescopic rod, it can detach from the detection platform, enabling flexible movement and detection.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figure 1-6As shown, the dual-purpose β-γ radiation simultaneous detection device in this embodiment includes a housing 10, a detection platform 50, a main controller 70, a telescopic rod 110, and a probe 40. The main controller 70 and the detection platform 50 are disposed inside the housing 10. The main controller 70 is connected to the probe 40. The telescopic rod 110 is detachably mounted on the housing 10. A first mounting position is provided inside the housing 10, and a second mounting position is provided on the telescopic rod 110. The probe 40 can be selectively mounted on either the first or the second mounting position. When the probe 40 is mounted on the first mounting position, the probe 40 faces the detection platform 50.

[0034] By allowing the probe 40 to be selectively installed in either a first or second mounting position, when the probe 40 is in the first mounting position, it can be used in conjunction with the detection platform 50 to detect radioactive samples placed on the platform 50. This is suitable for small samples that are easy to place on a platform. When the probe 40 is installed in the second mounting position on the telescopic rod 110, it can be detached from the detection platform 50, enabling flexible mobile detection. This allows for the detection of large, specially located radioactive sites or objects, such as those located at high altitudes or inconvenient to move, meeting the needs of different detection environments and objects.

[0035] The telescopic rod 110 is detachably mounted on the housing 10, allowing it to be stored in the housing 10 when not in use, saving space and making it easy to carry. Meanwhile, the main controller 70 and the testing platform 50 are housed inside the housing 10, resulting in a compact overall structure that facilitates the transport and storage of the device. It can be easily operated whether moved within the laboratory or used for field testing.

[0036] A first installation position is set inside the housing 10 so that the probe 40 can be stably oriented toward the testing platform 50 during desktop testing, ensuring the stability of sample testing and helping to obtain accurate test data; while the telescopic rod 110 provides reliable support for the probe 40 during mobile testing, and the staff can adjust the testing position and angle according to the actual situation to further ensure the accuracy of the test.

[0037] The testing platform 50 is horizontally set inside the housing 10.

[0038] The main controller 70 can be connected to the probe 40 via wired or wireless connection.

[0039] The dual-purpose β-γ radiation simultaneous detection device also includes a power module 80. Both the main controller 70 and the power module 80 are housed inside the enclosure 10 and located on the side of the detection platform 50. The probe 40, the main controller 70, and the power module 80 are electrically connected to each other using conventional techniques in the art. Specifically, the probe 40 employs a β-γ multilayer scintillator probe, enabling the discrimination and simultaneous measurement of β and γ particles. The main controller 70 can be an HEC-CG257B series digital pulse analyzer. The power module 80 can be a lithium battery commonly used in the art.

[0040] The housing 10 has several heat dissipation holes 12 on both sides to dissipate the heat generated by the probe 40, main controller 70 and power module 80 during operation.

[0041] The detection platform 50 can be either a desktop structure or a lifting structure, such as the scissor lift platform commonly used in this field, so as to facilitate the adjustment of the distance between the radioactive sample and the probe 40.

[0042] The box body 10 includes a box opening and a right-angle box door 20. The box opening is located on two adjacent side walls of the box body 10, and the right-angle box door 20 is hinged to the side wall of the box body 10 to open or close the box opening.

[0043] By placing the openings on two adjacent side walls of the enclosure 10, and hinged the right-angle door 20 to the side walls of the enclosure 10, the opening area is increased. When opened, this allows users to more easily access components such as the detection platform 50 and probe 40 inside the enclosure 10, and also makes it easier to place or remove radioactive samples from the detection platform 50. The larger opening space also makes installation, disassembly, and maintenance of the probe 40 more convenient, reducing operational difficulty and improving work efficiency.

[0044] The right-angle door 20 is located at the corner of the front side of the box body 10, and one end is hinged to the side wall of the box body 10.

[0045] Among them, the projection of the right-angle box door 20 in the horizontal plane is approximately right-angled.

[0046] The housing 10 is equipped with a winder 60, and the probe 40 is connected to the main controller 70 via a connecting wire 170, which is located on the winder 60.

[0047] The probe 40 is connected to the main controller 70 via the connecting cable 170, and the connecting cable 170 is mounted on the winding device 60 for orderly storage. When the position of the probe 40 needs to be adjusted for testing, the connecting cable 170 can be easily pulled out or retracted from the winding device 60, making the operation more convenient and efficient. For example, during mobile testing, the operator can easily pull out the probe 40 and the connecting cable 170 and connect them to the telescopic rod 110 without being bothered by tangled wires.

[0048] The winding device 60 is located on the inner side wall of the housing 10. The winding device 60 is equipped with a connecting line 170 that is connected to the probe 40. The winding device 60 also adopts existing technology, such as the winding device disclosed in patent CN222249592U.

[0049] The top of the right-angle door 20 is provided with a notch 21 for the connecting line 170 to pass through.

[0050] A clamp 90 is provided at the first installation position inside the housing 10, and the probe 40 is detachably connected to the clamp 90.

[0051] By setting up the clamp 90, a detachable connection can be achieved between the probe 40 and the housing 10. When placing the sample on the detection platform 50 for desktop detection, the probe 40 can be easily mounted on the clamp 90, ensuring that the probe 40 is stably facing the detection platform 50 and guaranteeing the stability of the detection process. When it is necessary to switch to mobile detection mode, or to perform maintenance operations such as cleaning, calibration, or replacement of the probe 40, the probe 40 can be easily removed from the clamp 90, making the operation simple and quick, and improving work efficiency.

[0052] The clamp 90 is connected to the top wall of the housing 10 via the connecting plate 100.

[0053] Specifically, the clamp 90 can be a high-pressure clamp from the prior art.

[0054] The housing 10 is provided with a mounting slot, and the telescopic rod 110 can be inserted into or removed from the mounting slot.

[0055] By allowing the telescopic rod 110 to be inserted into or removed from the mounting slot, when the telescopic rod 110 is not used for mobile testing, it can be inserted into the mounting slot for storage, making the overall structure more compact, reducing space occupation, and making it convenient to carry and store.

[0056] The mounting slot provides a relatively fixed and protected space for the telescopic rod 110. During the movement or storage of the detection device, the telescopic rod 110 is stored in the mounting slot, which can prevent it from being damaged by collisions, scratches, etc., extend the service life of the telescopic rod 110, ensure that the telescopic rod 110 can extend and retract normally during use, and maintain the stable detection function of the detection device.

[0057] When switching from desktop to mobile detection, simply remove the telescopic rod 110 from the mounting slot and install the probe 40 onto the telescopic rod 110. Conversely, to switch back from mobile to desktop detection, insert the telescopic rod 110 into the mounting slot and then install the probe 40 back into the first mounting position inside the housing 10. The entire switching process is simple to operate, improving the flexibility of the device.

[0058] The mounting groove is vertically arranged on the housing 10, with the bottom of the mounting groove closed and the opening of the mounting groove opened on the top surface of the housing 10.

[0059] Specifically, the telescopic rod 110 is inserted vertically downwards into the mounting slot. The telescopic rod 110 is then moved vertically upwards out of the mounting slot.

[0060] The telescopic rod 110 includes a connecting end and a holding end. The second installation position is set on the connecting end, and the holding end is provided with a lifting ring. When the telescopic rod 110 is inserted into the installation groove, the connecting end is at the bottom of the installation groove, and the holding end is at the opening of the installation groove. The opening is provided with a movable cover plate 120.

[0061] By providing a lifting ring on the grip end, it is easy for the operator to pull the telescopic rod 110 out of the mounting groove through the lifting ring.

[0062] The length of the mounting groove is slightly greater than the length of the telescopic rod 110, providing space for the lifting ring.

[0063] Specifically, a limiting screw 130 is provided on the top surface of the housing 10. The limiting screw 130 is located near the opening of the mounting groove. An arc-shaped groove 140 is provided on the movable cover plate 120 along the circumferential direction. The size of the end of the arc-shaped groove 140 is larger than the size of the end cap of the limiting screw 130, and smaller than the size of the end cap of the limiting screw 130 at other positions. The opening of the mounting groove can be opened or closed by rotating the movable cover plate 120.

[0064] The screen bracket 30 includes a screen positioning plate 31, a first ball joint 32, a second ball joint 33, a first clamping plate 34, a second clamping plate 35, and a locking screw 36. The top of the housing 10 is provided with a groove 11. The first ball joint 32 is fixedly disposed at the bottom of the groove 11, and the second ball joint 33 is fixedly disposed on the screen positioning plate 31. The first clamping plate 34 and the second clamping plate 35 are arranged opposite to each other. The upper end of the first clamping plate 34 and the upper end of the second clamping plate 35 are connected to the ball joint of the first ball joint 32 through a clamping assembly. The lower end of the first clamping plate 34 and the lower end of the second clamping plate 35 are connected to the ball joint of the second ball joint 33 through a clamping assembly. The locking screw 36 passes through the first clamping plate 34 and is threadedly connected to the second clamping plate 35.

[0065] The clamping assembly includes a first arc-shaped block 37 and a second arc-shaped block 38. The first arc-shaped block 37 is fixedly mounted on the first clamping plate 34, and the second arc-shaped block 38 is fixedly mounted on the second clamping plate 35. The ball head is clamped between the arc-shaped portion of the first arc-shaped block 37 and the arc-shaped portion of the second arc-shaped block 38.

[0066] There are two of each of the first arc-shaped block 37 and the second arc-shaped block 38, which are referred to as two pairs. One pair is located at the upper end of the first clamping plate 34 and the upper end of the second clamping plate 35, and the other pair is located at the lower end of the first clamping plate 34 and the lower end of the second clamping plate 35.

[0067] The area of ​​the groove 11 is larger than the area of ​​the screen bracket 30. The screen bracket 30 is movably set in the groove 11. The screen bracket 30 can be used to place a display screen or tablet computer for detection, and its position and angle can be adjusted. After use, it can be stored in the groove 11 as a whole.

[0068] The second ball head 33 is fixedly mounted on the back of the screen positioning plate 31.

[0069] When the locking screw 36 locks the first clamping plate 34 and the second clamping plate 35, the first arc-shaped block 37 and the second arc-shaped block 38 wrap around both sides of the ball head, thus clamping and fixing the ball head. When the locking screw 36 unlocks the first clamping plate 34 and the second clamping plate 35, the clamping assembly can rotate around the ball head, thereby adjusting the position and angle of the screen positioning plate 31, and the screen bracket 30 can be folded and stored in the groove 11.

[0070] The top of the box 10 is provided with a receiving groove 13, and a handle 160 is rotatably connected inside the receiving groove 13.

[0071] The receiving groove 13 is located on the top wall of the box 10 and is located in front of the groove 11.

[0072] The device is equipped with a rotating shaft 150 on one side inside the receiving slot 13. The two ends of the rotating shaft 150 are connected to handles 160, which allow the device to be moved around freely.

[0073] The housing 10 is equipped with a storage chamber, which contains a spare clamp 190 and a universal joint 200. An auxiliary door 180 is provided at the storage chamber to open or close the storage chamber.

[0074] The spare clamp 190 can be connected to the telescopic rod 110 via the universal joint 200.

[0075] Specifically, when used as a mobile detection device, the operator carries the housing 10 with one hand and holds the telescopic rod 110 with the other. One end of the connecting cable 170 is pulled out from inside the housing 10 via the winding device 60 and connected to the probe 40.
