Description

Technical Field

[0001] This utility model relates to the field of lead glass plates, and more particularly to a fireproof and radiation-proof lead glass plate that can be quickly spliced. Background Technology

[0002] In the fields of nuclear industry, medical care, and scientific research, lead glass plates are widely used as an important shielding and protective material in scenarios that require blocking ionizing radiation such as X-rays and gamma rays, such as radiology examination rooms in hospitals, observation windows in nuclear reactors, and radioactive material storage facilities.

[0003] For example, the "Radiation-Proof Lead Glass Splicing Structure" disclosed in patent number CN202320567890.1 uses bolt-through fastening, which requires 2 to 3 people to cooperate in supporting and positioning. The average time for splicing a single piece is 15 to 20 minutes. Moreover, the glass edges are prone to cracking due to uneven force during the bolt tightening process. The splicing seam relies on a single rubber sealing strip for sealing. After long-term use, the sealing strip ages and gaps are prone to appear. According to the test, when the radiation dose rate is 2mSv / h, the radiation leakage at the gap reaches 0.15mSv / h, which exceeds the standard of "peripheral dose equivalent rate ≤0.05mSv / h" in GBZ130-2020 "Radiation Diagnosis Radiation Protection Requirements". At the same time, the sealing strip has poor high temperature resistance and melts within 30 seconds in an 800℃ fire environment, which cannot prevent flame penetration. For example, the "Quick-Assembly Radiation-Proof Lead Glass" disclosed in patent number CN202221876543.8 uses a snap-fit ​​connection, which simplifies the installation steps, but the fit gap between the snap and the slot cannot be adjusted. The measured average width of the splice seam is 0.8 to 1.2 mm, which not only increases the risk of radiation leakage but also reduces the fireproof sealing performance. In the standard fire resistance test, the flame spread time through the splice seam is only 2 minutes, which is far below the requirement of "fire resistance limit of Class A fire-resistant components ≥ 1.5 hours" in GB / T9978.1-2021 "Fire Resistance Test Method for Building Components". Moreover, the structure does not have a buffer mechanism, and the snaps are easy to fall off during transportation or under vibration, resulting in the failure of the splice structure. Therefore, a quick-assembly fireproof and radiation-proof lead glass panel is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fireproof and radiation-proof lead glass plate that can be quickly spliced, aiming to improve the problems of low splicing efficiency and insufficient sealing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fireproof and radiation-proof lead glass plate that can be quickly spliced, comprising a mounting frame, wherein a lead glass plate is disposed in a groove on the front surface of the mounting frame, and splicing components are disposed at both ends of the rear surface of the mounting frame. The splicing components include positioning strips, wherein positioning holes are provided at both the upper and lower ends of the positioning strips, and adjustment holes are provided at the axial center of the front surface of the positioning strips. Sliding grooves are provided on both the left and right surfaces of the positioning strips, wherein a sliding plate is slidably connected to the inner wall of the sliding grooves, and a shaped block is fixedly connected to the front surface of the sliding plate. A locking block is elastically connected to the right surface of the shaped block by a spring.

[0006] As a further description of the above technical solution: the lead-coated glass plate includes an outer surface protective layer, the outer surface protective layer is wrapped with a fire-resistant reinforced substrate layer, the fire-resistant reinforced substrate layer is provided with a nano-level fire-resistant adhesive layer, and a core radiation-proof lead base layer is provided at the center of the nano-level fire-resistant adhesive layer.

[0007] As a further description of the above technical solution: the left end of the spring is fixedly connected to the right surface of the irregular block, and the right end of the spring is fixedly connected to the left surface of the locking block.

[0008] As a further description of the above technical solution: the inner wall of the adjustment hole is detachably connected with an adjustment bolt.

[0009] As a further description of the above technical solution: the outer wall of the adjusting bolt is in contact with the outer wall of the irregular block.

[0010] As a further description of the above technical solution: the inner wall of the positioning hole is detachably connected with a positioning bolt.

[0011] As a further description of the above technical solution: the top corner of the outer wall of the mounting frame is set as a rounded corner structure.

[0012] As a further description of the above technical solution: the front surface of the positioning strip is fixedly connected to the rear surface of the mounting frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the splicing process is simplified by utilizing the interrelationships between components such as positioning strips, positioning bolts, and locking blocks in the equipment, and through the synergistic effect of positioning bolts and adjusting bolts. Experimental data shows that it only takes 3-5 minutes for a single person to complete the splicing of a single lead glass plate, which is more than 70% more efficient than the traditional bolt fastening method (15-20 minutes / plate). The adjusting bolts can precisely adjust the position of irregularly shaped blocks, controlling the splicing seam width to 0.1-0.2mm, thus solving the problem of uncontrollable gaps in traditional snap-fit ​​connections.

[0015] 2. In this utility model, the lead-collecting glass plate in the equipment adopts a multi-layer composite structure with mutual cooperation between the core lead base layer to ensure radiation protection performance, the outer protective and fireproof substrate layer to improve weather resistance and high temperature resistance, and the nano adhesive layer to achieve room temperature bonding and high temperature expansion sealing, thus synergistically achieving the dual functions of fire protection and radiation protection. Moreover, the synergistic effect of each layer enhances the overall structural strength and extends the service life. Attached Figure Description

[0024] 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.

[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a fireproof and radiation-proof lead glass plate that can be quickly assembled, including a mounting frame 2. The top corner of the outer wall of the mounting frame 2 is set with a rounded corner structure. The mounting frame 2 is used to fix and support the lead glass plate 1. The groove on its front surface provides installation space for the lead glass plate 1, ensuring the stable assembly of the lead glass plate 1. The rounded corner structure of the top corner of the outer wall can reduce the impact damage during installation and use, and at the same time improve the overall safety and aesthetics of the device. It provides an installation base for the splicing components 5, realizing the rapid splicing and combination of multiple glass plates. The lead glass plate 1 is set in the groove on the front surface of the mounting frame 2. The lead glass plate 1 is the core functional component of the device, integrating fireproof and radiation-proof performance. It achieves radiation shielding and flame blocking through a multi-layer composite structure. At the same time, it serves as an observation carrier to meet the needs of light transmission observation. It is the main structure that realizes the dual functions of fireproof and radiation-proof. The splicing components 5 are set at both ends of the rear surface of the mounting frame 2.

[0026] Reference Figure 3 - Figure 5The splicing component 5 includes a positioning strip 51. The front surface of the positioning strip 51 is fixedly connected to the rear surface of the mounting frame 2. The positioning strip 51 provides a mounting carrier for structures such as positioning holes 52, adjustment holes 53, and sliding grooves 54. It provides basic support for splicing positioning through cooperation with adjacent devices. Positioning holes 52 are provided at both the upper and lower ends of the positioning strip 51. The positioning holes 52 provide installation channels for positioning bolts 3. The positioning bolts 3 connect the positioning strip 51 to the adjacent structure to achieve initial positioning and limit horizontal displacement. The positioning bolts 3 are detachably connected to the inner wall of the positioning holes 52. An adjustment hole 53 is provided at the axial center of the front surface of the positioning strip 51. The adjustment hole 53 is used to install adjustment bolts 4. The adjustment bolts 4 can extend and retract within the hole through threaded engagement. 4. The shaped block 55 provides operating space. The inner wall of the adjustment hole 53 is detachably connected to the adjustment bolt 4. The left and right surfaces of the positioning strip 51 are provided with sliding grooves 54. The sliding grooves 54 provide a guide track for the sliding of the slide plate 56, restricting the movement direction of the slide plate 56 and ensuring that the shaped block 55 and the locking block 58 move along the predetermined trajectory during adjustment. The slide plate 56 is slidably connected to the inner wall of the sliding groove 54. The slide plate 56 slides together with the shaped block 55 in the sliding groove 54, which serves to connect the shaped block 55 and the positioning strip 51 and ensure the stability of the movement of the shaped block 55. The front surface of the slide plate 56 is fixedly connected to the shaped block 55. Under the push of the adjustment bolt 4, the shaped block 55 drives the slide plate 56 to slide along the sliding groove 54, while providing mounting support for the spring 57 and the locking block 58. The support facilitates force transmission. The outer wall of the adjusting bolt 4 contacts the outer wall of the irregular block 55. A locking block 58 is elastically connected to the right surface of the irregular block 55 via a spring 57. Under the action of the spring 57, the locking block 58 engages with the corresponding locking structure of the adjacent device to achieve the locking function after splicing, preventing the splicing structure from loosening and ensuring the overall stability of the spliced ​​glass panels. It also helps enhance the sealing performance at the splicing point. The left end of the spring 57 is fixedly connected to the right surface of the irregular block 55, and the right end of the spring 57 is fixedly connected to the left surface of the locking block 58. The spring 57 has elastic deformation capability, providing a buffer force when the locking block 58 contacts the adjacent structure, ensuring that the locking block 58 fits tightly against the adjacent structure, enhancing the sealing and firmness of the splicing. When the splicing is released... The locking block 58 is reset through elastic recovery. The spring 57 is a cylindrical helical compression spring made of stainless steel, model Y20×40×1.5. The free length of this spring is 40mm, and the elastic force is 50-80N when the compression is 10-15mm. It can ensure that the locking block 58 fits tightly with the adjacent structure (to achieve a seal) without deforming the locking block 58 or the positioning strip 51 due to excessive elastic force. Its working temperature range is -40℃-300℃, which can withstand the high temperature environment in the early stage of a fire. It can prevent the splicing structure from loosening due to the failure of the spring 57, ensure the continuity of fireproof and radiation protection performance, prevent rusting in humid or radiation environments, ensure elastic stability during long-term use, and adapt to the environmental requirements of special scenarios such as medical and nuclear industries.

[0027] Reference Figure 1 , Figure 3 and Figure 6 The lead-concentrated glass panel 1 includes an outer surface protective layer 11. This outer surface protective layer 11, as the outermost structure of the lead-concentrated glass panel 1, is in direct contact with the external environment, resisting physical impacts such as collisions and friction, and chemical corrosion such as moisture and acid / alkali erosion. It protects the internal structures from damage and possesses flame-retardant properties, delaying the attack of flames on the internal structure and maintaining the integrity of the glass panel's appearance and light transmission. The outer surface protective layer 11, wrapped on the outermost side, is made of flame-retardant polycarbonate material with a thickness of 2-3 mm, resisting physical impacts and chemical corrosion. Inside the outer surface protective layer 11 is a fire-resistant reinforced substrate layer 12. This fire-resistant reinforced substrate layer 12 is made of high-temperature resistant material, significantly improving the high-temperature resistance and structural strength of the lead-concentrated glass panel 1, preventing deformation and cracking of the glass panel under high-temperature conditions. It uses high-temperature resistant quartz glass fiber board with a thickness of 5-8 mm and a high-temperature resistance limit ≥1200℃, enhancing the glass panel's impact resistance and reducing damage caused by external forces. This serves as the core radiation-shielding lead base. Layer 14 provides stable support and protection. A nano-level fire-retardant adhesive layer 13 is disposed inside the fire-retardant reinforced substrate layer 12. The nano-level fire-retardant adhesive layer 13 acts as an adhesive bond, ensuring a tight bond between the layers and preventing interlayer separation. The nano-level fire-retardant adhesive layer 13 fills the space between the fire-retardant reinforced substrate layer 12 and the core radiation-shielding lead base layer 14, using an intumescent graphite-based fire-retardant adhesive (model: FR-GP-01), with a viscosity of 8000-10000 mPa·s at room temperature and ≥300℃ at high temperatures. With an expansion ratio of 30-50 times, it can fill the gaps between layers. It expands under high temperature conditions, filling the tiny gaps between layers, which not only blocks the penetration of flames but also prevents radiation from leaking out of the gaps, enhancing the overall fire resistance and radiation protection sealing. The core radiation protection lead base layer 14 is set at the center of the nano-level fireproof adhesive layer 13. The core radiation protection lead base layer 14 is made of high-density lead material, using high-density lead plates with a purity of ≥99.99%. The thickness is designed to be 10-20mm according to the protection level. The shielding rate of 100keV X-rays is ≥99.9%. It utilizes the strong absorption capacity of lead for ionizing radiation such as X-rays and gamma rays to achieve effective radiation shielding. It is the core guarantee of the radiation protection function of the lead composite glass plate 1. Its thickness is designed according to the required protection level.

[0028] Working principle:

[0029] The mounting frame 2 serves as the core load-bearing structure. Its front surface groove is used to embed the lead-collecting glass plate 1. The frame and the glass plate are tightly fitted together to achieve initial fixation, ensuring that the lead-collecting glass plate 1 does not shift during use. The rounded corner structure of the top corner of the outer wall of the mounting frame 2 reduces the risk of bumps during assembly, while providing a stable installation benchmark for the splicing component 5, so that the connection between adjacent glass plates is evenly stressed.

[0030] The positioning strip 51 in the splicing assembly 5 is fixedly connected to the mounting frame 2 via its front surface, serving as a bridge connecting adjacent devices. When splicing multiple glass panels, the positioning holes 52 at both ends of the positioning strip 51 are aligned with the corresponding through holes in the adjacent mounting frame 2. The positioning bolts 3 are then inserted and pre-tightened. The threaded connection restricts the relative displacement of the two glass panels in the horizontal and vertical directions, completing the initial positioning. During this process, the fitting accuracy between the positioning holes 52 and the positioning bolts 3 ensures a uniform splicing gap, providing a foundation for subsequent sealing. The adjusting bolts 4 in the adjusting holes 53 are rotated, and the adjusting bolts 4 are extended and retracted axially using threaded transmission. Its outer wall contacts the inclined surface of the irregular block 55 and generates a thrust, pushing the irregular block 55 to drive the slide plate 56 to slide along the slide groove 54. The guiding effect of the slide groove 54 ensures that the irregular block 55 moves only in the horizontal direction and avoids deviation. As the irregular block 55 moves, the locking block 58 connected to its right side by the spring 57 gradually approaches the locking groove of the adjacent positioning strip 51. The spring 57 generates elastic force due to compression, so that the locking block 58 is tightly embedded in the locking groove to achieve mechanical locking. During this process, the buffering effect of the spring 57 can compensate for installation errors, ensure the tight fit between the locking block 58 and the locking groove, and prevent loosening due to vibration after splicing.

[0031] The core radiation-shielding lead base layer 14 of the lead-coated glass panel 1 is made of high-density lead material. Through the absorption and scattering of ionizing radiation such as X-rays and gamma rays by lead atoms, a radiation shielding barrier is formed. The nano-level fire-retardant adhesive layer 13 tightly bonds the fire-retardant reinforced substrate layer 12 and the core radiation-shielding lead base layer 14 at room temperature, preventing gaps between layers that could lead to radiation leakage. Under high temperature conditions, the interlayer adhesive layer expands, further filling the tiny gaps and ensuring the continuity of radiation shielding. The outer surface protective layer 11 serves as the first fire barrier. Its flame-retardant properties delay the direct contact of flames with the inner structure. The fire-retardant reinforced substrate layer 12 is made of high-temperature resistant material and can withstand temperatures of ≥1000℃, preventing the glass panel from deforming and collapsing in a fire. At the same time, it protects the core radiation-shielding lead base layer 14 from high-temperature damage. The nano-level fire-retardant adhesive layer 13 expands when exposed to fire, not only blocking the path of flame penetration but also enhancing the interlayer seal through expansion pressure, thus synergistically preventing heat transfer and radiation leakage.

[0032] The mechanical locking of the splicing component 5 ensures a tight joint between adjacent glass panels. Combined with the multi-layer protective structure of the lead-coated glass panel 1, the overall device not only has the convenience of quick assembly, but also maintains the continuity of fireproof and radiation protection performance at the splicing points. In the event of a fire or radiation environment, the double fixing of the positioning bolt 3 and the locking block 58 ensures structural stability, the preload of the spring 57 maintains the sealing of the splicing joint, and the synergistic effect of each layer of the lead-coated glass panel 1 achieves effective blocking of radiation and flames.
