Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof and explosion-suppressing materials, specifically a metal spherical explosion-proof and explosion-suppressing material. Background Technology

[0002] With rapid societal development, the demand for gasoline, diesel, and flammable and explosive hazardous chemicals continues to increase. During transportation, storage, and refueling sites are often located close to residential areas and buildings, posing significant safety hazards. Therefore, explosion-proof and anti-explosion materials are installed inside transport tank trucks and storage tanks. In extreme circumstances, such as lightning strikes, external impacts causing rupture, or fire, these materials prevent deflagration and explosion, greatly reducing the risk of accidental damage.

[0003] Existing explosion-proof and blast-suppressing materials are cylinders composed of multiple three-dimensional polygons. Their large size makes mechanical filling inconvenient, requiring manual entry into the tank for loading. This confined space greatly increases the risk of workplace injuries. Furthermore, some storage tanks have been used and may contain residual hazardous liquids or gases, further increasing the risk of injury or even death to workers. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a metal spherical explosion-proof and explosion-suppressing material, thereby solving the problem that in the prior art, the explosion-proof and explosion-suppressing material requires manual entry into the tank for filling.

[0005] A metal spherical explosion-proof and explosion-suppressing material, comprising a hollowed-out sphere obtained by deforming a thin metal sheet;

[0006] The metal sheet has multiple staggered cuts;

[0007] The cuts are distributed along a predetermined deformation path of the metal sheet.

[0008] Preferably, the metal sheet is stretched along a direction perpendicular to the cut to form a three-dimensional mesh structure;

[0009] The three-dimensional mesh structure is shaped into a sphere, and the spherical structure maintains a certain shape stability.

[0010] Preferably, the metal sheet is made of a lightweight metal material that has good toughness and elasticity.

[0011] Preferably, the shape of the cut includes, but is not limited to, a straight line, an arc, a wave, and a V-shape.

[0012] Preferably, after the three-dimensional mesh structure is shaped into a sphere, it maintains its spherical shape through its own toughness and elasticity, and is not easily deformed or scattered.

[0013] Preferably, the incision length L is 10-18mm, the distance H1 between adjacent incisions is 3-7mm, and the parallel distance H2 between incisions is 1-2mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By creating multiple staggered cuts on a metal sheet and distributing these cuts along a predetermined deformation path, the metal sheet can deform along the predetermined path when stretched, forming a three-dimensional mesh structure. This design greatly improves the material's deformability and adaptability, allowing the material to be molded into spheres or other shapes according to actual needs, meeting the requirements of different application scenarios. At the same time, it can be directly filled into oil tanks mechanically, avoiding the need for personnel to enter the oil tanks for filling.

[0016] The three-dimensional mesh structure, through the multi-level pores it forms, can effectively prevent flammable and explosive substances from undergoing chain reactions under dangerous conditions such as open flame, high temperature, impact or discharge, thereby inhibiting deflagration or explosion and minimizing the risk of disaster.

[0017] By simply stretching and kneading, the material can be processed into a spherical structure without the need for complex processing equipment and processes. This simplifies the processing, improves production efficiency, and reduces production costs.

[0018] By precisely controlling the shape, size, and spacing of the cuts, and utilizing the shape retention and energy absorption and dispersion capabilities of the three-dimensional mesh structure, the explosion-proof and explosion-suppression performance of the material is significantly enhanced.

[0026] 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.

[0027] like Figure 1 and Figure 2 As shown:

[0028] Example 1: This utility model provides a metal spherical explosion-proof and explosion-suppressing material, comprising a hollowed-out sphere obtained by deforming a metal sheet 1;

[0029] Multiple slits 2 are staggered on the metal sheet 1;

[0030] The cuts 2 are distributed along the predetermined deformation path of the metal sheet 1;

[0031] Among them, the metal sheet 1 is the basic component of the material. The metal sheet has good ductility and strength and can withstand certain pressure and impact.

[0032] The choice of metal sheet can be determined based on the specific application environment and explosion suppression requirements, such as stainless steel, aluminum alloy, etc.

[0033] Multiple cuts are staggered on the metal sheet, and these cuts are distributed along the predetermined deformation path of the metal sheet.

[0034] The shape, size, and spacing of the cuts can be designed and adjusted according to the required three-dimensional mesh structure.

[0035] The presence of slits allows the metal sheet to deform along a predetermined path when stretched, forming a three-dimensional mesh structure.

[0036] like Figure 6 As shown: Specifically, the metal sheet 1 is stretched along a direction perpendicular to the cut 2 to form a three-dimensional mesh structure;

[0037] The three-dimensional mesh structure is molded into a sphere, and the structure maintains a certain degree of shape stability after being molded into a sphere.

[0038] As can be seen from the above, by making multiple cuts in a staggered manner on the metal sheet and distributing these cuts along a predetermined deformation path, the metal sheet can deform along the predetermined path when stretched, forming a three-dimensional mesh structure. This design greatly improves the material's deformability and adaptability, allowing the material to be molded into spheres or other shapes according to actual needs, meeting the requirements of different application scenarios.

[0039] The three-dimensional mesh structure, through its multi-level pores, effectively prevents flammable and explosive substances from undergoing chain reactions under dangerous conditions such as open flames, high temperatures, impacts, or electrical discharges, thereby suppressing deflagration or explosions and minimizing the risk of disaster. Therefore, the metal spherical explosion-proof and explosion-suppressing material provided by this invention has stronger explosion-proof and explosion-suppressing performance.

[0040] Once molded into a spherical shape, the structure maintains a certain degree of shape stability, making it less prone to crumbling or deforming. This shape stability is crucial for explosion-proof and explosion-suppressing materials, as it ensures that the material retains its effective explosion-proof and explosion-suppressing performance during long-term use, without its effectiveness diminishing due to changes in shape.

[0041] Example 2: This example is basically the same as the previous example, except that the metal sheet 1 is made of a lightweight metal material with good toughness and elasticity.

[0042] As can be seen from the above, the metal sheet 1 is made of a lightweight metal material with good toughness and elasticity. This material selection aims to reduce the overall weight of the material while maintaining or enhancing its explosion-proof and explosion-suppressing performance;

[0043] Specifically, the metal sheet 1 is made of aluminum alloy. Due to its low density, high strength, good toughness, and strong corrosion resistance, aluminum alloy is an ideal choice for making explosion-proof and explosion-suppressing materials. It can not only reduce the weight of the material, but also maintain good deformation capacity when subjected to impact or pressure, thereby absorbing and dispersing the energy generated by the explosion.

[0044] like Figure 4 and Figure 5 As shown:

[0045] Specifically, the shape of cut 2 includes, but is not limited to, straight lines, arcs, waves, and V-shapes.

[0046] Specifically, after being shaped into a sphere, the three-dimensional mesh structure maintains its spherical shape through its own toughness and elasticity, making it less prone to deformation or falling apart.

[0047] like Figure 3 As shown:

[0048] Specifically, the length L of incision 2 is 10-18mm, the distance H1 between adjacent incisions 2 is 3-7mm, and the parallel distance H2 between incisions 2 is 1-2mm.

[0049] As can be seen from the above, if Figure 4 and Figure 5 As shown, the shape design of the notch 2 is diverse, including but not limited to straight lines, arcs, waves, and V-shapes. This diverse design allows the metal sheet 1 to form a more complex and three-dimensional mesh structure during stretching, thereby enhancing the material's ability to absorb and disperse energy;

[0050] When the metal sheet 1 is stretched along the direction of the cut 2 to form a three-dimensional mesh structure, this structure, after being shaped into a sphere, can maintain its spherical shape due to its own toughness and elasticity, and is not easily deformed or scattered. This shape stability is crucial for explosion-proof and explosion-suppressing materials, as it ensures that the material can continue to effectively perform its explosion-proof and explosion-suppressing functions during long-term use.

[0051] When subjected to impact or pressure, the three-dimensional mesh structure can effectively absorb and disperse energy through its complex geometry and porous structure, thereby reducing the destructive force of an explosion.

[0052] The length L of slit 2 is precisely controlled within the range of 10-18mm. This length range ensures that the slit can form a sufficient three-dimensional mesh structure during stretching, while avoiding a decrease in material strength due to excessively long slits. The distance H1 between adjacent slits 2 is controlled within the range of 3-7mm. This distance ensures that the metal parts between the slits maintain sufficient connection strength during stretching, thereby ensuring the overall stability of the three-dimensional mesh structure. The parallel distance H2 between slits 2 is controlled within the range of 1-2mm. This distance ensures that the metal parts between the slits can form a uniform three-dimensional mesh structure during stretching, while avoiding mutual interference between slits due to excessively close distances.

[0053] like Figure 6 As shown: The processing method of metal spherical explosion-proof and explosion-suppressing materials includes the following steps:

[0054] I. Material Preparation

[0055] Select metal sheets: Based on the specific usage environment and explosion suppression requirements, select metal materials with good ductility and strength to make metal sheets1, such as stainless steel, aluminum alloy, etc.

[0056] II. Cut Design and Processing

[0057] Design the shape and size of the cut: such as Figure 4 and Figure 5 As shown, the shape of the cut 2 is designed, including but not limited to straight lines, arcs, waves, and V-shapes, to enhance the material's ability to absorb and disperse energy. Here, a straight line is chosen, and the length L of the cut 2 is determined to be 10 mm, the distance H1 between adjacent cuts 2 is 3 mm, and the parallel distance H2 between cuts 2 is 1 mm.

[0058] Processing cuts: Multiple cuts 2 are staggered on the metal sheet 1, distributed along the predetermined deformation path of the metal sheet. A precision rolling tool is used to roll and press the cuts to ensure that the shape, size, and spacing of the cuts meet the design requirements.

[0059] III. Formation of Three-Dimensional Network Structure

[0060] Stretched metal sheets: such as Figure 6 As shown, the metal sheet 1 is stretched along a direction perpendicular to the cut 2. During the stretching process, the metal sheet deforms along a predetermined path to form a three-dimensional mesh structure.

[0061] IV. Spherical Kneading and Shape Stability

[0062] Kneading into a spherical shape: The formed three-dimensional mesh structure is further kneaded to stack it into a three-dimensional mesh structure; during the kneading process, the toughness and elasticity of the metal sheet are used to maintain the spherical structure with a certain shape stability; it can also be formed by mechanical spinning for mass production and speed up the forming process.

[0063] Check shape stability: Inspect the kneaded spherical structure to ensure it does not easily deform or fall apart. This shape stability is crucial for explosion-proof and explosion-suppressing materials because it ensures that the material can continue to effectively perform its explosion-proof and explosion-suppressing functions during long-term use.

[0064] V. Finished Product Inspection and Packaging

[0065] Finished product inspection: The processed metal spherical explosion-proof and explosion-suppressing materials are inspected to ensure that they meet the design requirements and relevant standards.
