Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof ball technology, and specifically relates to an explosion-proof ball. Background Technology

[0002] In recent years, with the increasingly widespread use of flammable and explosive liquids (gases) such as gasoline, liquefied petroleum gas, and propane in industrial production, transportation, and civilian storage, the safety protection of their storage containers (such as storage tanks, fuel tanks, and gas cylinders) has become increasingly prominent. During storage, flammable gas mixtures can easily form above the liquid surface. Once combustion and explosion occur due to equipment aging, improper operation, or accidental ignition sources, the pressure wave generated by the propagation of the flame can rapidly compress unburned gases within milliseconds, leading to container explosions. This not only damages equipment but can also trigger chain reactions, causing significant casualties and property losses.

[0003] While existing explosion-proof balls are commonly used protective devices, they still have certain shortcomings in practical applications: the metal skeleton of traditional explosion-proof balls often adopts a simple rectangular mesh design, which has weak tensile strength. When faced with the impact of combustion and explosion, it is prone to local fracture due to stress concentration, making it difficult to effectively disperse and resist the explosion pressure; lacking a dedicated buffer structure, it relies solely on the rigidity of the metal itself to resist explosion, which cannot absorb the instantaneous energy generated by the explosion. As a result, the skeleton suffers severe fatigue damage after long-term impact, and its service life is greatly shortened. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof ball to solve the problems mentioned in the background art, such as the weak tensile strength of traditional explosion-proof balls, the lack of a dedicated buffer structure, and the inability to absorb the instantaneous energy generated by an explosion.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof sphere, comprising a sphere and metal columns fixed at both ends of the sphere. The sphere is composed of multiple sets of metal mesh skeletons. The metal mesh skeletons are made of metal sheets with wavy oblique grooves processed on the surface. A composite buffer layer is hot-pressed onto the inner side of the metal mesh skeletons. A nano-functional coating is sprayed onto the outer side of the metal mesh skeletons. Multiple elastic self-tightening buckles are embedded in the metal mesh skeletons. An annular connecting buckle is provided at the equator position of the sphere.

[0006] In a further embodiment, one end of the metal mesh frame is provided with a plurality of protruding teeth, and the other end of the metal mesh frame is provided with a plurality of grooves that match the protruding teeth.

[0007] In a further embodiment, the metal pillar is a copper boss structure, and the metal pillar is externally connected to an anti-static wire.

[0008] In a further embodiment, the inner wall of the sphere is provided with multiple slots, and the elastic self-fastening buckle is made of nylon, which elastically opens after being rolled into a ball and engages with the slots on the inner wall of the sphere.

[0009] The technical effects and advantages of this utility model are as follows: This explosion-proof sphere features a wavy, obliquely grooved metal mesh frame that creates a diamond-shaped wavy mesh. Compared to traditional rectangular mesh, this effectively improves tensile strength, efficiently disperses explosive impact energy, and prevents stress concentration-induced breakage. Furthermore, multiple metal mesh frames interlock with protruding teeth and grooves, and are secured by elastic self-tightening buckles and inner wall grooves, forming a stable spherical structure that is not easily disintegrated under explosive impact. The composite buffer layer (silicone matrix + glass microspheres + flame retardant) inside the metal mesh skeleton absorbs the instantaneous energy of the explosion through deformation, reduces the stress on the metal mesh skeleton, and significantly extends the product's service life. The copper metal pillars at both ends are connected to anti-static wires, which can quickly discharge the static electricity accumulated inside the sphere, thus avoiding the risk of static electricity igniting the flammable mixture from the source. The nano-functional coating on the outside of the metal mesh skeleton can block the direct contact between the flame and the metal, reducing metal oxidation damage. At the same time, the flame retardant in the composite buffer layer further enhances the flame resistance and improves the explosion-proof reliability. The ring-shaped connecting buckle at the equator of the sphere supports the series or parallel connection of multiple explosion-proof spheres via chains, straps, or bolts. The protection range can be flexibly adjusted according to the container volume, adapting to the explosion-proof requirements of different scenarios such as storage tanks, oil tanks, and pipelines. It is highly practical. This explosion-proof sphere can efficiently disperse the impact energy of an explosion, greatly improving the explosion-proof capability. At the same time, it can discharge static electricity inside the container in real time, eliminating the risk of static electricity igniting flammable gas mixtures from the source.

[0013] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0014] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0015] This utility model provides, for example Figure 1-3 The explosion-proof sphere shown includes a sphere 1 and metal posts 9 fixed to both ends of the sphere 1. The sphere 1 is composed of multiple sets of metal mesh skeletons 2. The metal mesh skeletons 2 are made of metal sheets with wavy oblique grooves on the surface. The wavy grooves make the mesh holes diamond-shaped. Compared with traditional rectangular mesh holes, the tensile strength is effectively improved. One end of the metal mesh skeleton 2 is provided with multiple protruding teeth 6, and the other end of the metal mesh skeleton 2 is provided with multiple grooves 7 that match the protruding teeth 6. After being stretched, broken, and curled, the multiple metal mesh skeletons 2 form a spherical structure by self-interlocking through the protruding teeth 6 and grooves 7. The metal mesh skeleton 2 is embedded with multiple elastic self-fastening buckles 5. The inner wall of the sphere 1 is provided with multiple slots. The elastic self-fastening buckles 5 are made of nylon. After being curled into a sphere, they elastically open and engage with the slots on the inner wall of the sphere 1. The equatorial position of the sphere 1 is provided with an annular connecting buckle 8. The annular connecting buckle 8 supports the series or parallel connection of multiple explosion-proof spheres through chains, straps, or bolts. The inner side of the metal mesh skeleton 2 is hot-pressed with a composite buffer layer 3, which is made of a mixture of silicone matrix, glass microspheres and flame retardant. The silicone matrix accounts for 60% to 80%, the glass microspheres account for 10% to 30%, and the flame retardant accounts for 5% to 15%. The thickness after lamination is 1 to 3 mm. The composite buffer layer 3 absorbs the instantaneous energy of the explosion through deformation, reducing the stress of the metal mesh skeleton 2. The outer side of the metal mesh skeleton 2 is sprayed with a nano-functional coating 4, which is an Al2O3-TiO2 nano-ceramic coating that can prevent the flame from directly contacting the metal mesh skeleton 2. The metal column 9 is a copper boss structure, and the metal column 9 is connected to an anti-static wire, which can quickly discharge the static electricity in the sphere 1, eliminating the risk of static electricity igniting the flammable mixture from the source. All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings.

[0016] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Working principle: When the storage container explodes, the explosion-proof ball provides protection through the synergistic effect of its multi-layer structure: First, the nano-functional coating 4 on the outside of the metal mesh skeleton 2 prevents the flame from directly contacting the metal, reducing the damage to the skeleton caused by high temperature. At the same time, the inner composite buffer layer 3 absorbs part of the instantaneous energy of the explosion through its own deformation, reducing the impact on the metal mesh skeleton 2. The diamond-shaped corrugated mesh of the metal mesh skeleton 2 disperses the remaining impact force to the entire sphere 1. Combined with the self-interlocking structure of the protrusions 6 and grooves 7, and the engagement of the elastic self-fastening buckle 5 with the inner wall groove, the overall stability of the sphere 1 is ensured, preventing breakage and disintegration. The copper metal pillars 9 at both ends discharge static electricity from the sphere 1 in real time through external anti-static wires to prevent secondary ignition. If multiple spheres are used in combination, the ring connecting buckle 8 disperses the impact force to multiple spheres 1, further expanding the protection range and ultimately achieving highly efficient explosion protection.
