Description

Technical Field

[0001] This utility model relates to the field of metal detection spectrometer technology, and in particular to a metal detection spectrometer with radiation protection function. Background Technology

[0002] Metal detection spectrometers, as key equipment in industrial testing and materials analysis, primarily utilize spectral monitoring technology to accurately detect the composition and properties of metals. In practical applications, these devices often face complex electromagnetic environments or potential radiation interference, especially at the connection between the spectrometer's monitoring head and the outer casing. Insufficient sealing can allow radiation to penetrate the device, affecting sensor accuracy and circuit stability, thus reducing the reliability of the detection results. Therefore, developing a metal detection spectrometer with efficient radiation protection is crucial for improving its performance in harsh environments. Current technologies typically employ static sealing structures for radiation protection in metal detection spectrometers, such as using fixed sealing rings or sealant layers at component connections, relying on mechanical clamping to fill gaps. The underlying principle of these structures is to create a barrier to radiation propagation through the physical contact of rigid or elastic materials. Some devices also add protective coatings or shielding covers to the outside of the casing, using the inherent shielding properties of the materials to reduce the impact of external radiation on internal components. However, these solutions generally rely on fixed sealing methods and lack dynamic adaptive adjustment mechanisms.

[0003] However, with prolonged use, existing spectrometers are prone to component wear, external vibration, temperature changes, and other factors. This can cause deformation or loss of fit in the fixing seals, allowing radiation to seep into the interior through gaps and failing to provide lasting and reliable protection for the core detection components. This issue directly affects the stability of the equipment in high-radiation environments, limiting the application of metal detection spectrometers in scenarios with extremely high radiation protection requirements, such as the nuclear industry and radioactive material detection. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a metal detection spectrometer with anti-radiation function. It aims to improve the problem that when existing spectrometers are used for a long time, the fixed seals are prone to deformation failure or decreased fit due to wear of components or external vibration, temperature changes and other factors. This allows radiation to still seep into the interior through the connection gaps, making it impossible to form a lasting and reliable protection for the core detection element.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal detection spectrometer with anti-radiation function, comprising a spectrometer monitoring head, a spectrometer housing provided on one side of the outer wall of the spectrometer monitoring head, a handle fixedly connected to the lower surface of the spectrometer housing, a light source provided inside the spectrometer monitoring head, a sealing ring one fixedly connected inside the spectrometer monitoring head near the side of the spectrometer housing, a sealing ring two slidably connected inside the spectrometer housing near the side of the spectrometer monitoring head, a propulsion component provided inside the sealing ring two, and the sealing ring one and the sealing ring two fitting together;

[0006] The propulsion assembly includes a slide rod 2 and a spring 2. One end of the slide rod 2 is fixedly connected to the inside of the sealing ring 2, and the other end of the slide rod 2 is slidably connected to the inside of the spectrometer housing. The spring 2 is sleeved on the outer wall of the slide rod 2, and one end of the spring 2 is fixedly connected to the inside of the spectrometer housing, while the other end of the spring 2 is fixedly connected to the inside of the sealing ring 2.

[0007] Furthermore, a protective ring is fixedly connected to the outer wall of the spectrometer monitoring head, a hinge is fixedly connected to the lower surface of the protective ring, a baffle is fixedly connected to one side of the outer wall of the hinge, and a sealing gasket is fixedly connected to one side of the outer wall of the baffle.

[0008] Furthermore, a locking block is fixedly connected to the upper side of the outer wall of the baffle, a locking block is slidably connected inside the protective ring, a reset component is provided on one side of the outer wall of the locking block, and a driving component is provided on the upper surface of the locking block.

[0009] Furthermore, the reset assembly includes a slide rod, one end of which is fixedly connected to the outer wall of the snap-fit ​​block, the outer wall of which is slidably connected to the inside of the protective ring, and a spring is sleeved on the outer wall of which.

[0010] Furthermore, the drive assembly includes a connecting plate, the bottom of which is fixedly connected to the upper surface of the snap-fit ​​block, and a push plate is rotatably connected inside the protective ring.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, a linkage structure of sealing ring one, sealing ring two, and spring two is set at the connection between the spectrometer monitoring head and the spectrometer housing. The elastic thrust of spring two causes sealing ring two to slide inside the housing and fit tightly with sealing ring one, forming a stable and reliable sealing structure. This effectively prevents radiation from penetrating into the equipment through the connection, thus building a radiation protection barrier from a physical level. This protects the internal components of the spectrometer from radiation interference and improves the stability and reliability of the equipment in high-radiation environments.

[0013] 2. In this utility model, the connecting plate drives the locking block to disengage from the locking block, and with the assistance of spring one, the baffle is quickly released. Rotating the baffle around the hinge as the center opens the protective ring, making the operation simple and efficient. When closed, the baffle drives the sealing gasket to adhere to the inner wall of the protective ring. Combined with the guiding effect of the sliding rod on the extension and retraction of spring one, it ensures that the locking block accurately resets and limits its position, forming a double-seal protection. This facilitates equipment maintenance and testing operations, and the tight fit between the sealing gasket and the protective ring further isolates the external environment from the spectrometer monitoring end, effectively improving the equipment's protective performance and service life.

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

[0023] Reference Figures 1-4 This utility model provides an embodiment of a metal detection spectrometer with radiation protection function, including a spectrometer monitoring head 1. The spectrometer monitoring head 1 serves as the core input component for radiation detection, responsible for receiving spectral signals reflected / emitted by metal samples. A sealing ring 4 is embedded around its connecting end, providing a basic mounting carrier for the sealing structure. A spectrometer housing 2 is located on one side of the outer wall of the spectrometer monitoring head 1. The spectrometer housing 2 forms the main frame of the device, with a sliding groove on its inner wall for installing the sealing ring 5. A limiting boss fixes the rear end of a spring 7. A handle 3 is fixedly connected to the lower surface of the spectrometer housing 2. A light source 18 is located inside the spectrometer monitoring head 1. A sealing ring 4 is fixedly connected to the inside of the monitoring head 1 near the side of the spectrometer housing 2. A sealing ring 5 is slidably connected to the inside of the spectrometer housing 2 near the side of the monitoring head 1. The sealing ring 4 is fixed to the outer periphery of the connection end of the monitoring head 1. The front end is designed with a beveled structure to form a gradient contact surface with the rear bevel of the sealing ring 5. It directly fills the connection gap between the monitoring head and the housing and is the basic component for static sealing. The sealing ring 5 is installed in the sliding groove on the inner wall of the spectrometer housing 2 and can slide axially. The rear end abuts against the spring 7. The spring push makes the front bevel tightly engage with the sealing ring 4 to compensate for component deformation or wear. A propulsion component is set inside the sealing ring 5.

[0024] The propulsion assembly includes a slide rod 26 and a spring 27. One end of the slide rod 26 is fixedly connected to the inside of the sealing ring 25. The spring 27 provides a continuous elastic thrust, driving the sealing ring 25 to slide axially along the sliding groove, ensuring that the inclined surfaces of the double sealing rings always maintain a high-pressure fit. The other end of the slide rod 26 is slidably connected to the inside of the spectrometer housing 2. The spring 27 is sleeved on the outer wall of the slide rod 26. The sealing ring 14 fits against the sealing ring 25 and is located between the spectrometer monitoring head 1 and the spectrometer housing 2. The outer wall of the slide rod 26 is slidably connected to the inside of the spectrometer housing 2. One end of the spring 27 is fixedly connected to the inside of the spectrometer housing 2, and the other end of the spring 27 is fixedly connected to the inside of the sealing ring 25.

[0025] Specifically, in the protective structure connecting the spectrometer monitoring head 1 and the spectrometer housing 2, sealing ring 4 and sealing ring 5 constitute a dual dynamic sealing assembly: sealing ring 4 is fixedly embedded in the outer periphery of the connecting end of the spectrometer monitoring head 1, while sealing ring 5 is adapted to be installed in the sliding groove on the inner wall of the spectrometer housing 2, with its back abutting against one end of spring 7, and the other end of spring 7 fixed to the limiting protrusion on the inner wall of the spectrometer housing 2. During equipment assembly, the elastic thrust of spring 7 drives sealing ring 5 to slide axially along the sliding groove on the inner wall of the spectrometer housing 2, causing the front bevel of sealing ring 5 to form a gradient fit with the rear bevel of sealing ring 4, filling the connection gap through the tight engagement of the double bevels. This structure utilizes the continuous elastic force of spring 7 to compensate for deformation caused by component wear or environmental stress, ensuring that the connection between the spectrometer monitoring head 1 and the spectrometer housing 2 always maintains a high-pressure seal, effectively preventing X-rays, gamma rays, and other radiation from seeping into the equipment through the connection gap, providing durable and reliable radiation shielding protection for the spectrometer's core detection circuit and sensors.

[0026] Reference Figures 4-6A protective ring 8 is fixedly connected to the outer wall of the spectrometer monitoring head 1. The protective ring 8 is an annular protective structure surrounding the spectrometer monitoring end. Its inner wall has a locking groove and a sealing groove, used for mechanical locking of the locking block 15 and sealing of the sealing gasket 11, respectively. A hinge 9 is fixedly connected to the lower surface of the protective ring 8. The hinge 9 serves as the rotation fulcrum of the baffle 10, allowing the baffle 10 to rotate around the hinge 9, thus opening and closing the protective ring 8. A baffle 10 is fixedly connected to one side of the outer wall of the hinge 9. The baffle 10 is hinged to the edge of the protective ring 8. An operating handle is provided on the side, and a locking block 12 and a sealing gasket 11 are fixed on the inner side. A sealing gasket 11 is fixedly connected to one side of the outer wall of the baffle 10. The sealing gasket 11 is fixed to the inner edge of the baffle 10 and is made of elastic silicone. When the baffle 10 is closed, it fits into the annular sealing groove of the inner wall of the protective ring 8, blocking dust, moisture and radiation from entering the interior through the opening of the protective ring 8. A locking block 12 is fixedly connected to the upper side of the outer wall of the baffle 10. The locking block 12 is installed inside the baffle 10 and moves into the locking groove of the inner wall of the protective ring 8 as the baffle 10 moves. Its groove structure and locking mechanism are designed to engage with the baffle 10. Block 15 engages to form a mechanical lock, preventing the baffle 10 from opening accidentally. A locking block 15 is slidably connected inside the protective ring 8. A reset component is provided on one side of the outer wall of the locking block 15. A drive component and a reset component are provided on the upper surface of the locking block 15. The reset component includes a slide rod 13. The slide rod 13 is fixed to the inner wall of the protective ring 8, fitted with a spring 14, and passes through the guide hole of the connecting plate 16, providing linear guidance for the spring's extension and retraction and the movement of the connecting plate 16, ensuring the precise movement trajectory of the locking block 15. One end of the slide rod 13 is fixedly connected to the locking block. The outer wall of the slide rod 13 is slidably connected to the inside of the protective ring 8. The outer wall of the slide rod 13 is fitted with a spring 14. The spring 14 is fitted on the slide rod 13 and its two ends are respectively connected to the inner wall of the protective ring 8 and the connecting plate 16. When the locking block 15 is disengaged from the locking block 12, it is compressed and stored, and provides rebound power when resetting, which helps the connecting plate 16 and the locking block 15 to return to their positions quickly. The drive assembly includes the connecting plate 16. The bottom of the connecting plate 16 is fixedly connected to the upper surface of the locking block 15. The inside of the protective ring 8 is rotatably connected to a push plate 17.

[0027] Specifically, the drive push plate 17 is a circular turntable with teeth on its outer circumference, coaxially mounted in the bearing seat at the top of the protective ring 8, with its lower end face contacting the wedge-shaped drive block of the connecting plate 16. When the drive push plate 17 is rotated clockwise, the inclined toothed surface of its lower end face pushes the connecting plate 16 to slide outward, causing the locking block 15 fixed to the end of the connecting plate 16 to disengage from the groove limiting structure of the locking block 12. At this time, the spring 14 fitted on the slide rod 13 is compressed and stored due to the movement of the connecting plate 16, and the baffle 10 loses the limiting of the locking block 15, and can rotate downward around the hinge 9 to open the protective ring 8. After the equipment maintenance is completed, the baffle 10 is pulled back to the opening of the protective ring 8, and the locking block 12 on the inner side of the baffle 10 moves with the baffle 10 into the slot on the inner wall of the protective ring 8, triggering the spring 14 to rebound and push the connecting plate 16 back to reset, so that the locking block 15 is re-locked into the groove of the locking block 12. During this process, the sealing gasket 11 fixed to the inner edge of the baffle 10 rotates with the baffle 10 and fits into the annular sealing groove on the inner wall of the protective ring 8. Combined with the linear guiding effect of the slide rod 13 on the extension and retraction of the spring 14, the protective ring 8 can be opened and closed quickly and the sealing performance can be guaranteed. This not only facilitates the maintenance and operation of the spectrometer monitoring end by the testing personnel, but also isolates the monitoring end from external dust, moisture and radiation through the precise fit between the sealing gasket 11 and the protective ring 8.

[0028] Working principle: When this metal detection spectrometer is used, the connection between the spectrometer monitoring head 1 and the spectrometer housing 2 is filled by sealing ring 4 and sealing ring 5. At the same time, spring 7 pushes sealing ring 5 to slide inside the spectrometer housing 2, so that sealing ring 5 and sealing ring 4 fit tightly together, thereby stably sealing the connection between the spectrometer monitoring head 1 and the spectrometer housing 2 and preventing radiation from affecting the inside through the connection between the spectrometer monitoring head 1 and the spectrometer housing 2.

[0029] Furthermore, the drive push plate 17 rotates inside the protective ring 8, thereby applying pressure to the connecting plate 16, causing the connecting plate 16 to drive the locking block 15 to slide inside the protective ring 8. When the locking block 15 disengages from the outer wall of the locking block 12, the baffle 10 is released. At the same time, the spring 14 retracts, and then the baffle 10 is pulled to rotate around the hinge 9, thus opening the protective ring 8. After the pressure is applied, the baffle 10 is pulled to the outer wall of the protective ring 8, thereby driving the locking block 12 to move inside the protective ring 8. At this time, the rebound of the spring 14 drives the locking block 15 to move to the outer wall of the connecting plate 16, thus limiting the connection plate 16 and the baffle 10. During this process, the extension and retraction of the spring 14 is guided by the slide rod 13, and at the same time, the movement of the baffle 10 drives the sealing gasket 11 to move to the inner wall of the protective ring 8, thus sealing the protective ring 8 and protecting the internal spectrometer monitoring end.

[0030] 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.
