Description

Technical Field

[0001] This utility model relates to the field of pyrotechnics transportation technology, and in particular to an electromagnetic protection box for pyrotechnics transportation and detection. Background Technology

[0002] Explosives are a general term for disposable components and devices containing gunpowder or explosives that, upon exposure to external stimuli, will burn or explode to ignite the gunpowder, detonate the explosive, or perform mechanical work. They include percussion caps, primers, ignition tubes, delay devices, detonators, detonating cords, fuses, detonating wires, as well as explosive switches, explosive bolts, starters, and cutting cords.

[0003] Electrically activated pyrotechnics primarily rely on the heat generated by an electric current passing through components such as bridge wires to detonate or ignite. They are characterized by high precision, good repeatability, higher safety compared to traditional pyrotechnics, flexible energy adjustment, and wide applicability. However, during use, electromagnetic radiation can induce currents in the conductive components of pyrotechnics, such as the lead wires and bridge wires. According to the law of electromagnetic induction, when a changing magnetic field passes through a closed circuit, an induced electromotive force is generated, resulting in an induced current. For pyrotechnics, these additional induced currents can interfere with their normal detonation current. Electromagnetic radiation environments of varying intensities and characteristics can increase the risk of accidental detonation and reduce the reliability of detonation in electrically activated pyrotechnics. Long-term effects may also lead to degradation of pyrotechnic material properties and changes in the stability of the propellant.

[0004] Existing pyrotechnic storage boxes mainly consider requirements such as shock resistance, waterproofing, and electromagnetic radiation protection during storage. The storage environment for pyrotechnics is relatively stable and safe. However, during transportation and use, pyrotechnics are more susceptible to safety accidents caused by environmental electromagnetic radiation. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies where pyrotechnic products are easily affected by environmental electromagnetic radiation during transportation and use, resulting in safety accidents, this utility model provides an electromagnetic protection box for the transportation and testing of pyrotechnic products.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an electromagnetic protection box for transporting and testing pyrotechnic products, including a box body, a box cover installed on the top of the box body, a waterproof edge formed by bending sheet metal at the upper port edge of the box body, a water vapor sealing ring fixed on the bottom platform of the waterproof edge, a conductive sealing ring fixed on the bottom inner side of the box cover, an observation window installed on the box cover, the observation window being flexible shielding glass, grooves provided on both the left and right sides of the box body, an electromagnetic shielding sleeve extending into the box body provided on the grooves, and a side opening cover installed on the box body corresponding to the outer side of the electromagnetic shielding sleeve.

[0007] As a further improvement of this utility model, a handle is installed on the top of the box lid.

[0008] As a further improvement of this utility model, the rear side of the lid is mounted on the box body by a hinge, and the front side of the lid is connected to the box body by a metal latch.

[0009] As a further improvement of this utility model, the electromagnetic shielding sleeve is fixed to the groove by a pressure ring.

[0010] As a further improvement of this utility model, the side-opening cover is fixed to the box body with screws.

[0011] As a further improvement of this utility model, a moisture-proof pad and conductive sound-absorbing cotton are laid on the top of the box.

[0012] Compared with the prior art, the present invention has the following advantages: In this solution, an observation window is fixedly embedded on the lid, which facilitates the dispensing of pyrotechnic products from the storage box according to usage requirements and facilitates the testing of pyrotechnic products before use. The conductive sealing ring can contact and abut against the waterproof edge of the upper port of the box to form a reliable electrical connection, which plays a role in electromagnetic protection, effectively improving the performance stability of pyrotechnic products and reducing the probability of accidental safety accidents. Before using pyrotechnic products, the electromagnetic shielding sleeve is used for protective testing, which effectively ensures the quality and performance of pyrotechnic products.

[0019] To make the technical solution and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0020] Reference Figures 1 to 3 This utility model discloses an electromagnetic protection box for transporting and inspecting pyrotechnic products, including a box body 1, a box cover 2 installed on the top of the box body 1, a waterproof edge 5 formed by bending sheet metal at the upper port edge of the box body 1, a water vapor sealing ring 6 fixed on the bottom platform of the waterproof edge 5, a conductive sealing ring 7 fixed on the bottom inner side of the box cover 2, an observation window 8 installed on the box cover 2, the observation window 8 being flexible shielding glass, grooves 4 provided on both the left and right sides of the box body 1, an electromagnetic shielding sleeve 12 extending into the box body 1 provided on the grooves 4, and a side opening cover 3 installed on the box body 1 corresponding to the outer side of the electromagnetic shielding sleeve 12.

[0021] The box 1 is made of metal, and grooves 4 are made on both sides of the box 1 to accommodate the side-opening cover 3. Depending on the characteristics of the object being protected, materials such as moisture-proof pads and conductive sound-absorbing cotton can be laid inside the box 1 to achieve functions such as shock absorption and moisture protection during transportation.

[0022] Reference Figure 4 The upper edge of the enclosure 1 is bent into a waterproof edge 5. A moisture-sealing ring 6 is fixed to the bottom platform of the waterproof edge 5 to prevent moisture. The cover 2 is located on the upper part of the enclosure. A conductive sealing ring 7 is fixed to the inner bottom of the cover 2. When the cover 2 is closed, the conductive sealing ring 7 can contact and abut against the waterproof edge 5 at the upper end of the enclosure 1 to form a reliable electrical connection and provide electromagnetic protection.

[0023] A handle 14 is installed on the upper part of the lid 2 for easy handling and transportation. The front of the lid 2 is connected to the main body of the protective case by a metal latch 9, and the rear is connected by a hinge 10. An observation window 8 is fixedly embedded in the center of the surface of the lid 2. The observation window 8 is a flexible shielding glass, a transparent shielding material proposed for electromagnetic protection of electronic device displays and viewing windows. It is made by sandwiching a specially processed metal mesh between two layers of glass and forming it through thermal bonding. It can block and attenuate electromagnetic waves and prevent the shielding glass from distorting the various graphics observed, with high fidelity and high definition. It is widely used to reinforce the observation parts of displays and communication electronic equipment, and has the dual functions of electromagnetic compatibility and visibility. The observation window 8 is not used to check the quantity and model of the pyrotechnics to be used, but to facilitate performance testing during pre-use inspection.

[0024] The side-opening cover 3 is fixed to the housing 1 with screws 11. The side-opening cover 3 is made of the same material as the housing. During transportation, the two side-opening covers 3 are connected and fixed to the housing 1 with screws 11 to facilitate transportation and electromagnetic protection.

[0025] The electromagnetic shielding sleeve 12 is fixed to the groove 4 by the pressure ring 13. One end of the electromagnetic shielding sleeve 12 is closely fitted to the part that contacts the tester's hand by passing through an elastic band, and the other end is fixed to the inside of the groove 4 on both sides of the outer shell by the pressure ring 13. The pressure ring 13 is made of an aluminum frame with conductive anodizing treatment, and a conductive gasket can be installed between the electromagnetic shielding sleeve 12 and the pressure ring 13.

[0026] When conducting performance testing of pyrotechnic devices before use, the side-opening covers 3 on both sides are removed. Test personnel can then hold test probes with both hands and conduct tests inside the chamber through the test ports on both sides. The gaps at the test ports are protected by an electromagnetic shielding sleeve 12. The electromagnetic shielding sleeve 12 is made of double-layered electromagnetic shielding cloth, sewn together from this cloth. The electromagnetic shielding cloth is made of nylon or polyester fiber, deposited with metals or alloys such as copper, nickel, and silver through magnetron sputtering. The bottom layer of the fiber surface is highly conductive copper or silver, while the surface is coated with nickel to resist oxidation and corrosion. It possesses excellent conductivity and shielding effectiveness, as well as anti-oxidation and anti-corrosion properties. It is widely used in shielded machine rooms, shelters, and windows in classified locations, as well as for personal protection, and is an ideal material for shielding various electronic products.
