While these panels offer some explosion-proof performance, their effectiveness is limited and their sound insulation is poor in the event of a major explosion. Furthermore, with the development of modern technology, people have increasingly higher requirements for the performance of explosion-proof doors. They not only need to have excellent explosion-proof performance but also excellent sound insulation to prevent explosions from harming people inside the building. As a result, steel plate composite explosion-proof panels cannot meet these needs. Therefore, this utility model proposes a titanium alloy composite explosion-proof panel.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A titanium alloy composite explosion-proof panel includes an explosion-proof panel body; the explosion-proof panel body has a layered structure; the layered structure of the explosion-proof panel body consists of, from the outside to the inside, a tightly fitted explosion-proof layer, an impact-absorbing layer, and an explosion-proof sound-insulating layer; the explosion-proof layer is composed of titanium alloy plates; the impact-absorbing layer is composed of aluminum foam plates; the explosion-proof sound-insulating layer is composed of steel plate layer I and steel plate layer II and a set of H-beams; the set of H-beams is located between steel plate layer I and steel plate layer II; the outer wall of the layered explosion-proof panel body is provided with a sealing edge; the steel plate layer I and steel plate layer II and the set of H-beams are sealed and fitted together, and together with the sealing edge, form a sealed cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The connection between the titanium alloy plate and the aluminum foam plate, and between the aluminum foam plate and the steel plate layer I, is all by brazing. The thickness of the titanium alloy plate is 1-5cm, which gives the explosion-proof plate body good explosion-proof and impact-resistant capabilities while reducing the overall weight and improving convenience. The aluminum foam plate is a closed-cell aluminum foam plate with a thickness of 5-20cm and a porosity of 40%-80%, which improves its sound insulation and impact energy absorption effects. At the same time, because aluminum foam is a porous metal material prepared by foaming process, its density is only 0.25-0.6g / cm3, which is lower than the density of water, while its stiffness is 5 times that of steel. It has the characteristics of being lightweight and high-strength. The thicker aluminum foam plate does not add much weight while increasing the energy absorption and impact resistance of the explosion-proof plate body.
[0015] 2. By fixing steel pipes with a radius of 5-10cm in sequence, with the spacing between adjacent steel pipes being 0, the steel pipes cover one side of the outer wall of the titanium alloy plate, thus making it the first line of defense against explosion and impact. When the impact force hits the arc-shaped surface of the steel pipe, it can effectively disperse the impact force. This allows the steel pipe to improve the explosion-proof performance of the explosion-proof plate body while dispersing and reducing the impact force, thereby further enhancing the explosion-proof and impact-resistant capabilities of the explosion-proof plate body.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. 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.
[0021] Please see Figures 1-2As shown, a titanium alloy composite explosion-proof panel includes an explosion-proof panel body 8; the explosion-proof panel body 8 has a layered structure; the layered structure of the explosion-proof panel body 8 consists of, from the outside to the inside, a tightly fitted explosion-proof layer, an impact-absorbing layer, and an explosion-proof sound-insulating layer; the explosion-proof layer is composed of titanium alloy plates 1; the impact-absorbing layer is composed of aluminum foam plates 2; the explosion-proof sound-insulating layer is composed of steel plate layer I3 and steel plate layer II4 and a set of H-beams 5; the set of H-beams 5 is located between steel plate layer I3 and steel plate layer II4; the outer side wall of the layered explosion-proof panel body 8 is provided with a sealing edge 6; steel plate layer I3 and Steel plate layer II4 and a set of H-beams 5 are sealed together and form a sealed cavity with the sealing edge 6. Titanium alloy plate 1 serves as the outermost explosion-proof layer of the explosion-proof plate body 8. Because titanium alloy plate 1 has the advantages of high strength, good corrosion resistance and good heat resistance, it can effectively improve the impact resistance and heat deformation resistance of the explosion-proof plate body 8 as the explosion-proof layer. Then, aluminum foam plate 2 serves as the internal impact-absorbing layer of the explosion-proof plate body 8. Because aluminum foam is a porous metal material prepared by foaming process, its density is only 0.25~0.With a density of 6 g / cm³, lower than water but five times the stiffness of steel, aluminum foam possesses lightweight yet high strength characteristics, which facilitates the installation of the explosion-proof panel body 8. Furthermore, aluminum foam is one of the most ideal materials for energy absorption and impact resistance in industrial applications, with an energy absorption density of approximately 20 J / cm³. As part of the structure of the explosion-proof panel body 8, it effectively buffers and absorbs impact energy, thereby preventing personal injury and equipment damage, and improving the overall impact resistance of the explosion-proof panel body 8. Finally, an explosion-proof sound insulation layer is formed by steel plate layer I3, steel plate layer II4, and a set of H-beams 5. Steel plate layer I3 effectively enhances the deformation resistance of the aluminum foam board 2, and the H-beams 5 further enhance the deformation resistance and explosion-proof performance of the explosion-proof panel body 8; and the H-beams 5 and steel plate layer I3... The sealed cavity formed by the steel plate layer II4 and the sealing edge 6 can effectively block the transmission of sound, thereby improving the sound insulation effect of the explosion-proof plate body 8. Furthermore, the foamed aluminum plate 2 also has excellent sound absorption and insulation properties, further enhancing the sound insulation performance of the explosion-proof plate body 8. This results in the explosion-proof plate body 8 possessing not only excellent explosion-proof performance but also good sound insulation performance. A set of semi-circular steel pipes 7 are fixed to one side of the outer wall of the titanium alloy plate 1, with the arc surface of the steel pipes 7 facing the explosion-facing side. The two ends of the outer wall of the steel pipes 7 are flush with the opposite sides of the outer wall of the titanium alloy plate 1. When the titanium alloy plate 1 is impacted, the semi-circular steel pipes 7 will block part of the impact. The titanium alloy plate 1 is subjected to force, thereby enhancing its explosion-proof and impact-resistant performance. The connection between H-beams 5 and steel plate layer I3, and between H-beams 5 and steel plate layer II4, is achieved through bolting, welding, or a combination thereof. The sealing edge 6 is C-shaped steel. The sealing edge 6 is connected to the layered structure by welding. The H-beams 5 are vertically arranged, with a spacing of 10-30cm between adjacent H-beams 5, ensuring good sealing between H-beams 5 and steel plate layers I3 and II4, and allowing for the transfer of impact force during impacts, resulting in good and stable sound insulation. The connection between titanium alloy plate 1 and aluminum foam plate 2, and between aluminum foam plate 2 and steel plate layer I3, is achieved through brazing. The thickness of titanium alloy plate 1 is 1-5cm. The aluminum foam plate 2 is closed-cell aluminum foam. The explosion-proof board 8 has a closed-cell aluminum foam board 2 with a thickness of 5-20cm and a porosity of 40%-80%. The connection between the titanium alloy plate 1 and the aluminum foam board 2, and between the aluminum foam board 2 and the steel plate layer I3, is achieved through brazing. The thickness of the titanium alloy plate 1 is 1-5cm, which gives the explosion-proof board body 8 good explosion-proof and impact-resistant capabilities while reducing overall weight and improving convenience. Furthermore, the closed-cell aluminum foam board 2, with a thickness of 5-20cm and a porosity of 40%-80%, enhances its sound insulation and impact energy absorption effects. Since aluminum foam is a porous metal material prepared through a foaming process, its density is only 0.25-0.With a density of 6 g / cm³, lower than water, and a stiffness five times that of steel, it possesses the characteristics of being lightweight and high-strength. This allows the thicker foam aluminum board 2 to increase the energy absorption and impact resistance of the explosion-proof plate body 8 without significantly adding weight. The steel pipes 7, with a radius of 5-10 cm, are welded to the titanium alloy plate 1. The steel pipes 7 are sequentially fixed, with an 0-degree spacing between adjacent pipes, thus covering the outer wall of the titanium alloy plate 1. The side of the steel pipe 7 serves as the first line of defense against explosion and impact. When the impact force strikes the curved surface of the steel pipe 7, it effectively disperses the impact force, thus improving the explosion-proof performance of the explosion-proof plate body 8 while reducing the impact force, thereby further enhancing the explosion-proof and impact-resistant capabilities of the explosion-proof plate body 8. Square slots 9 are provided in the middle of adjacent sides of the outer wall of the sealing edge 6; a set of reserved holes 10 are provided in the middle of adjacent sides at the top of the outer wall of the sealing edge 6, and the two sets of reserved holes 10 correspond to a pair of square slots 9. The outer wall of the sealing edge 6 is connected; square clips 11 are fixed to the middle of the adjacent two sides, and the square clips 11 match the square slots 9; a set of threaded grooves 12 are opened at the top of the outer wall of each pair of square clips 11, and the two sets of threaded grooves 12 match the two sets of reserved holes 10. When the explosion-proof plate body 8 needs to be installed, the square clips 11 on the sealing edge 6 of one explosion-proof plate body 8 can be aligned with the square slots 9 on the other explosion-proof plate body 8 and inserted. Then, a bolt is passed through the reserved hole 10 and rotated into the threaded groove 12. This design securely connects the two explosion-proof panel bodies 8, allowing them to be transported without assembly until they reach their destination. This facilitates transport of the relatively small explosion-proof panel bodies 8. Furthermore, when a part of an explosion-proof panel body 8 is damaged and requires repair or replacement, only that individual panel body 8 can be disassembled and transported to a repair shop, making maintenance more convenient. Also, when a part is damaged, only the damaged part needs to be replaced, saving on replacement and repair costs.
[0022] Working Principle: The titanium alloy plate 1 serves as the outermost explosion-proof layer of the explosion-proof panel body 8. Due to its high strength, good corrosion resistance, good heat resistance, and light weight, the titanium alloy plate 1 effectively enhances the impact resistance and thermal deformation resistance of the explosion-proof panel body 8. The foamed aluminum plate 2 serves as the internal impact-absorbing layer of the explosion-proof panel body 8. Foamed aluminum is a porous metal material prepared through a foaming process, with a density of only 0.25–0.6 g / cm³, lower than water, while its stiffness is five times that of steel. Its lightweight and high-strength characteristics facilitate the installation of the explosion-proof panel body 8. Furthermore, foamed aluminum is one of the most ideal materials for energy absorption and impact resistance in industrial applications, with an energy absorption density of approximately 20 J / cm³. As part of the structure of the explosion-proof panel body 8, it effectively buffers and absorbs impact energy, thereby preventing personnel from being injured. To mitigate casualties and property damage, the overall impact resistance of the explosion-proof panel body 8 is enhanced. The foam aluminum board 2 is a closed-cell foam aluminum board with a thickness of 5-20cm and a porosity of 40%-80%, resulting in greater thickness and enhanced effectiveness without significantly increasing weight. Finally, an explosion-proof sound insulation layer is formed by steel plate layer I3, steel plate layer II4, and a set of H-beams 5. The connection between H-beams 5 and steel plate layer I3, and between H-beams 5 and steel plate layer II4, is either bolted, welded, or a combination thereof. The sealing edge 6 is a C-shaped steel; the connection between the sealing edge 6 and the layered structure is welded. The H-beams 5 are vertically arranged, with a spacing of 10-30cm between adjacent H-beams 5. This allows steel plate layer I3 to effectively enhance the deformation resistance of the foam aluminum board 2, and the H-beams 5 further improve the deformation resistance and explosion-proof performance of the explosion-proof panel body 8.The sealed cavity formed by H-beam 5, steel plate layer I3, steel plate layer II4, and sealing edge 6 effectively blocks sound transmission, thereby improving the sound insulation effect of the explosion-proof panel body 8. The foamed aluminum board 2 also has excellent sound absorption and insulation properties, further enhancing the sound insulation performance of the explosion-proof panel body 8. This results in the explosion-proof panel body 8 possessing not only excellent explosion-proof performance but also good sound insulation. A set of semi-circular steel pipes 7 with a radius of 5-10cm are fixed to one side of the outer wall of the titanium alloy plate 1. These steel pipes are sequentially fixed with zero spacing between adjacent pipes, covering one side of the outer wall of the titanium alloy plate 1. This forms the first line of defense against explosion and impact. When impact force strikes the curved surface of the steel pipes 7, it effectively disperses the impact force, thus improving the explosion-proof performance of the explosion-proof panel body 8 while reducing the impact force, further enhancing its explosion-proof and impact-resistant capabilities. The explosion-proof panel 8 possesses excellent explosion-proof and impact-resistant performance, good sound insulation, and is lightweight and convenient. During transportation and installation, the explosion-proof panel 8 can be transported and installed independently without assembly. Once in place, the square locking block 11 on the sealing edge 6 of one explosion-proof panel 8 is aligned with the square locking groove 9 on the other explosion-proof panel 8 and inserted. Then, bolts are passed through the pre-drilled holes 10 and turned into the threaded grooves 12, thus fixing the two explosion-proof panel 8s together. This allows for transport without assembly, making the relatively small explosion-proof panel 8 easy to transport. Furthermore, when a part of the explosion-proof panel 8 is damaged and requires repair or replacement, only that part can be disassembled for repair, eliminating the need to transport the entire panel to a repair shop. This makes maintenance more convenient, and when a part is damaged, only the damaged part needs to be replaced, saving on replacement and repair costs.
