As such, the explosive device for testing the initiating explosive device of the embodiment of the present disclosure can prevent the personnel from being injured due to the explosion during the testing.

As shown in fig. 1-2, the initiating explosive device testing explosion-proof apparatus 100 comprises an explosion-proof cylinder assembly 10, an initiating explosive device positioning platform 20, a first cap assembly 40 and a second cap assembly 50. In an embodiment, the explosion-proof cartridge assembly 10 includes an outer cartridge body 11, a cartridge base plate 12, a cavity 13, and a limit stop 14. The outer cylinder body 11 can be integrally formed by a high-strength alloy plate, can be deformed moderately, but cannot crack so as to ensure that the outer cylinder body meets the specified requirement on explosion-proof impact performance. The cylinder bottom plate 12 closes the bottom of the outer cylinder body 11, and can laterally reinforce and support the outer cylinder body 11. The cavity 13 is formed by the outer cylinder body 11 and the cylinder bottom plate 12. The limit stopper 14 is located at the top end of the outer cylinder body 11. In one example, as shown in fig. 3, the bump stopper 14 includes a first step portion 142 and a second step portion 144, and the second step portion 144 is located above the first step portion 142. In an embodiment, the initiating explosive device positioning platform 20 is used for accommodating the initiating explosive device to be tested, and the initiating explosive device positioning platform 20 is arranged in the cavity 13 and forms an explosion venting space 30 with the cylinder bottom plate 12.

In an embodiment, the first cap assembly 40 is disposed at the top end of the outer cartridge body 11 and seals the cavity 13. In one example, the first header assembly 40 includes a first header body 42 and a pressure relief feature 44 positioned below the first header body 42. The pressure reducing component 44 includes a deformable cavity 46, and when the initiating explosive device to be tested explodes, the deformable cavity 46 can block the energy and the explosive products at the beginning of the explosion on one hand, and absorb the energy generated by the explosion through the deformation of the deformable cavity 46 on the other hand. In the example of fig. 2, the deformable cavity 46 is rectangular in cross-section. It will be apparent to those skilled in the art that the deformable cavity 46 may have other cross-sections, such as square, oval, trapezoidal, etc., and the particular shape may be adjusted as desired. In an embodiment, the second header assembly 50 is disposed over the first header body 42. In one example, the second header assembly 50 includes a second header body 52, the second header body 52 being removably fittingly engaged with the positive stop 14. For example, the second cap body 52 may be fitted in the limit stop 14 by a shape-fitting manner, or fitted in the limit stop 14 by a screw-engagement manner, or fitted in the limit stop 14 by a snap-fit assembly. In an example, the second cap assembly 52 can be received in the second step 144 to achieve mating. For example, when the initiating explosive device to be tested explodes, the limit stopper 14 limits the second top cover body 52 by being assembled with the second top cover body 52, so that the second top cover body 52 is prevented from flying out from the upper side, for example, vertically, and energy generated by the explosion is blocked in the outer cylinder body 11, and thus, the operator is not injured.

In an embodiment, as shown in fig. 1-2, the initiating explosive device testing explosion-proof device 100 further comprises a wheel assembly 70, and the wheel assembly 70 carries the initiating explosive device testing explosion-proof device 100. The wheel assembly 70 allows the initiating explosive device testing explosion proof device 100 to be moved to meet the requirements of the test.

The wheel assembly 70 may include one, two, three, four or more wheels, and the specific number may be set as desired. In an embodiment, as shown in fig. 1-2, the initiating explosive device testing explosion-proof device 100 further comprises a grounding wire 80. In one example, the ground wire 80 is connected with the ground wire in the test explosion-proof room where the operator is located during the test, so that static electricity in the initiating explosive device test explosion-proof device can be eliminated in time.

In an embodiment, as shown in fig. 1-2, the explosion-proof cartridge assembly 10 further comprises a first collar 15, the first collar 15 supporting and reinforcing the outer cartridge body 11. In one example, the first collar 15 is proximate the top end of the outer barrel body 11 and surrounds the outer wall of the outer barrel body 11. In one example, when the limit stop 14 is installed, the first collar 15 is disposed in the first stepped portion 142 of the limit stop 14. In one example, the first collar 15 includes a lateral groove 152 on a side of the first collar 15, and the first header body 42 is received in the lateral groove 152 to prevent movement of the first header body 42 in a horizontal plane. For example, when the initiating explosive device to be tested explodes, the first collar 15 limits the first cap body 42, can bear initial detonation impact, can be deformed or cracked properly, and cannot be broken. In one example, the first collar 15 may be made of a metal material, but the embodiments of the present disclosure are not limited thereto, and may be adjusted as needed by those skilled in the art.

In the embodiment, as shown in fig. 1-2, the explosion-proof cylinder assembly 10 further comprises a pressure-reducing inner cylinder 16, and the pressure-reducing inner cylinder 16 is disposed around the inner wall of the outer cylinder body 11. In one example, the pressure relief inner barrel 16 includes at least two crush-absorbing panels 162 and a flame retardant layer 164 and a sound deadening layer 166 positioned between the at least two crush-absorbing panels 162, as shown in FIG. 4. The crumple energy-absorbing plate 162 absorbs energy generated by explosion through deformation of the crumple body; the refractory layer 164 may insulate against explosives, flames, etc.; the sound damping layer 166 may reduce noise generated by the explosion. Like this, explosion-proof barrel subassembly has reduced the impact on barrel side direction and vertical direction by a wide margin, has effectively reduced the risk that the explosion led to the fact the injury to operating personnel. In one example, the refractory layer 164 and the sound damping layer 166 are sequentially disposed between at least two of the corrugated energy absorbing plates 162. Preferably, the crumple energy absorbing plate 162 may be constructed of a metallic material such as aluminum or stainless steel; the refractory layer 164 may be composed of an asbestos material, silicon carbide, or diatomaceous earth; the sound attenuating material 166 may be comprised of sound attenuating cotton, inorganic foam sound attenuating material, or foam plastic material. It is to be understood that the embodiments of the present disclosure are not limited to these materials, and that modifications may be made by one skilled in the art as desired.

In an embodiment, as shown in fig. 1-2, the explosion proof barrel assembly 10 further includes a second collar 17, the second collar 17 supporting and reinforcing the outer barrel body 11. In one example, the second collar 17 surrounds the outer wall of the outer barrel body 11 and is located below the first collar 15. In the illustrated embodiment, the explosion proof barrel assembly 10 includes two second collars 17, but one skilled in the art may provide other numbers of second collars, such as one, three, four or more, as desired.

In an embodiment, as shown in FIG. 2, the cartridge base plate 12 includes a pressure relief vent 18. The pressure relief hole 18 guides energy generated when the initiating explosive device to be tested explodes to be discharged out of the initiating explosive device testing explosion-proof device 100 through the pressure relief hole 18, so that the energy generated by explosion is discharged downwards, and the upper and lateral protection safety of the initiating explosive device testing explosion-proof device 100 is guaranteed. In the illustrated embodiment, the pressure relief vent 18 is located in the center of the can bottom panel 12. It should be understood that the vent holes could also be located off-center on the can floor 12. In one example, the test cable is connected with the initiating explosive device to be tested through the pressure relief hole 18, and the cable plug is connected with the initiating explosive device to be tested on the initiating explosive device positioning platform 20, so that the explosion-proof performance of the initiating explosive device test explosion-proof device is not weakened.

In an embodiment, as shown in fig. 5, the first header body 42 includes a first center cap 422 and a first baffle 424 protruding along an outer circumference of the first center cap 422. The first center cap 422 is adapted to withstand an explosion impact, and may be appropriately deformed or cracked without being broken, so that safety of an operator may be secured. The first baffle 424 is disposed in the lateral groove 152 of the first collar 15 to prevent the first header body 42 from exiting the pyrotechnic test explosion proof device 100 from above when the pyrotechnic to be tested explodes. Thus, the first header body 42 may be a level 1 header body, thus constituting a primary explosion proof barrier in a vertical direction. The first baffle 424 may comprise one, two, three, four or more first baffles, preferably two or more evenly distributed first baffles. The first baffle 424 may be fan-shaped, rectangular, square or trapezoidal, etc., as long as it can be disposed in the lateral groove of the first collar. In one example, first center cap 422 and first baffle 424 are integrally formed from, for example, a high strength alloy sheet material to meet blast impact resistance requirements. It will be clear to the person skilled in the art that the first central cover and the first baffle plate can also be made of other suitable materials, as long as they allow a moderate deformation or cracking of the first central cover and the first baffle plate. Therefore, the first top cover assembly absorbs energy generated by explosion through moderate deformation or cracking, and the detonation power is weakened, so that the safe operation of the second top cover assembly is guaranteed. In an embodiment, as shown in fig. 5, the first header body 42 further includes a first handle 48 disposed on the first header body 42, the first handle 48 facilitating the operator's manipulation of the first header assembly 40. In one example, first handle 48 may be disposed on first central cover 422. In one example, the first handle 48 is operable in a lifted state and a stowed state, respectively. In the lifted state, the first handle 48 is placed vertically or in a direction inclined to the horizontal plane, so that the operator holds the first handle 48 to move the first cap body 42. For example, the first header body 42 is moved to the position of the first collar of the explosion proof cartridge assembly by the first handle 48, and then the first header body 42 is rotated in the horizontal plane to be rotated into the first step portion 142 of the limit stop 14 and the first header body 42 is limited in the horizontal direction. When the first header body 42 is in place, the first handle 48 is horizontally disposed and in a stowed position. The first handle 48 may include one, two, three or more first handles, and the specific number may be set as desired.

In an embodiment, as shown in fig. 6-7, the second header body 52 includes a second center cap 522 and a second baffle 524 protruding along an outer circumference of the second center cap 522. The second central cover 522 is used to withstand the explosion impact, and can be deformed moderately without cracking, so that the safety of the operator can be ensured. In one example, a second baffle 524 is disposed in the second step 144 of the positive stop 14 to prevent the second header body 52 from exiting the pyrotechnic test explosion protection device 100 from above when the pyrotechnic to be tested explodes. The second baffles 524 may comprise one, two, three, four or more second baffles, preferably two or more evenly distributed second baffles. The second stopper 524 may have a fan shape, a rectangular shape, a square shape, a trapezoidal shape, or the like, as long as it can be disposed in the second stepped portion of the limit stopper. In one example, second center cap 522 and second baffle 524 are integrally formed from, for example, a high strength alloy sheet material to meet blast impact resistance requirements. It is clear to the person skilled in the art that the second central cap and the second shutter can also be made of other suitable materials, as long as they allow a moderate deformation of the second central cap and the second shutter while ensuring that no cracks are formed. In this way, the second cover assembly further absorbs the energy of the explosion through moderate deformation, and simultaneously ensures the safety of the operator by ensuring that the second cover assembly does not crack, so the second cover assembly becomes a final protection layer for the operator. In an embodiment, as shown in fig. 6-7, the second header assembly 50 further includes a second handle 54 disposed on the second header body 52, the second handle 54 facilitating the operator's manipulation of the second header assembly 50. In one example, the second handle 54 may be disposed on the second central cover 522. In one example, the second handle 54 is operable in a lifted state and a restrained state. In the lifted state, the second handle 54 is placed vertically or in a direction inclined to the horizontal plane, so that the operator holds the second handle 54 to move the second cap body 52. For example, the second cover body 52 is moved to the upper end surface of the explosion proof cylinder assembly 10 by the second handle 54, and then the second cover body 85 is rotated in the horizontal plane to be turned into the second step portion 144 of the limit stop 14 and is limited by the side wall of the limit stop 14 in the horizontal direction, so that the second cover body 52 cannot rotate any more. As shown in fig. 7, in the restraining position, the second handle 54 is horizontally placed and restrains the second flap 524 in the horizontal direction. For example, when the second flap 524 is received in the second stepped portion 144 of the limit stop 14, the second handle 54 is unfolded to protrude out of the edge of the second roof body 52, so that the second handle 54 contacts the limit stop 14 to interfere with the rotation of the second roof body 52 when the second roof body 52 rotates (due to uneven force during an explosion). Thus, the second header body 52 may be a level 2 header body, thus constituting a vertically oriented primary burst disk. In an example, the second handle 54 can also operate in a stowed state. In the stowed position, as shown in fig. 6, the second handle 54 is positioned in a direction opposite the restraining position to facilitate subsequent manipulation. The second handle 54 may comprise one, two, three, four or more second handles, preferably two or more evenly distributed second handles, more preferably the same number of second handles and limit stops, and the specific number may be set as desired.

In the embodiment, the explosion-proof cylinder assembly 10, the first top cover assembly 40 and the second top cover assembly 50 are formed by integral processing, for example, made of high-strength alloy steel, so as to ensure the explosion-proof performance of the explosive device testing device.

In an embodiment, the two ends of the initiating explosive device positioning platform 20 can be fixed on the side wall of the pressure reducing inner cylinder 16, so that the initiating explosive device positioning platform 20, the cylinder bottom plate 12 and the pressure reducing inner cylinder 16 form an explosion venting space 30. In an embodiment, the initiating explosive device positioning platform 20 may be machined from a metallic material. In an embodiment, as shown in fig. 8, the initiating explosive device positioning platform 20 is provided with a positioning groove 22 penetrating through the initiating explosive device positioning platform 20, and the positioning groove 22 is used for accommodating the initiating explosive device to be tested and enabling the flame and explosive output end of the initiating explosive device to be tested to face the bottom plate 12 of the cylinder body, so as to perform pressure relief processing on the initiating explosive device. In one example, the positioning groove 22 includes a first guide groove 222 and a second guide groove 224 that are cylindrical, the second guide groove 224 is closer to the cartridge base plate 12 than the first guide groove 222, and the diameter of the second guide groove 224 is smaller than the diameter of the first guide groove 222, as shown in fig. 2. In an example, the cross-sectional shape of the positioning slot 22 is designed to be a reversed "convex" shape, and the flame and the output end of the explosive product of the initiating explosive device are led downward by the design, so that the energy and the product generated by the explosion can be guided into the pressure relief space 30 during the explosion process of the initiating explosive device, and the impact of the energy generated by the explosion on the cavity and the component above the initiating explosive device positioning platform 20 is reduced, so that most of the energy is guided into the pressure relief space for processing, and the protection effect on the operator is better realized. In one example, the initiating explosive device positioning platform 20 comprises one, two, three or more positioning grooves, and the specific number can be set as required.

In an embodiment, as shown in fig. 2, 9 and 10, the initiating explosive device testing explosion-proof device 100 further comprises an explosion venting buffering assembly 60 arranged in the explosion venting space 30. Explosion venting bumper assembly 60 may block at least a portion of the products of an explosion and may absorb energy generated by a portion of the explosion. In one example, the vent bumper assembly 60 includes at least two layers of extrudable honeycomb energy absorbing panels 62, a fire barrier layer 64, and an assembled pillar 66. Each of the at least two layers of honeycomb energy absorbing panels 62 is provided with a plurality of explosion venting holes 622. Each of the explosion venting holes 622 is designed to have a honeycomb structure, and the explosion venting holes are closely arranged to each other. When the initiating explosive device explodes, the plurality of explosion venting holes 622 in the honeycomb energy absorption plate absorb energy and vibration generated in the explosion process through deformation, so that the explosion venting and noise reduction effects are achieved. In one example, the explosion venting holes 622 in the honeycomb energy absorbing plates of two adjacent layers of the multi-layer honeycomb energy absorbing plate are arranged corresponding to each other up and down, so that a plurality of explosion venting channels are formed. When the initiating explosive device explodes, the unabsorbed small amount of energy and explosive products (such as gas or fragments) are discharged through the plurality of discharge channels to the bottom pressure discharge hole 18, and then discharged through the pressure discharge hole 18 to the outside of the initiating explosive device testing explosion-proof device 100. In this way, the greatly attenuated explosion energy is discharged from the initiating explosive device testing explosion proof apparatus 100, for example, via the pressure relief hole 18. In one example, the honeycomb energy absorbing panel 62 can be formed from steel or sheet metal. In one example, a fire barrier 64 is disposed between at least two crushable honeycomb energy absorbing panels 62 for fire protection. In one example, the fire barrier 64 may be made of an asbestos material, silicon carbide, or diatomaceous earth. In one example, the assembly studs 66 are used to secure the crushable honeycomb energy absorption panel 62 and the fire barrier 64 together. Explosion venting bumper assembly 60 may include one, two, three, four or more assembled columns, with the specific number being set as desired.

In an embodiment, when the initiating explosive device to be tested explodes unexpectedly, the detonation energy of the initiating explosive device inevitably causes the gas inside the cylinder to expand, so as to impact the cylinder body 11, the first cap body 42 and the second cap body 52. If the explosive product escapes from above in a lateral or vertical direction, it can cause injury to the operator. In the embodiment, the pressure reducing inner cylinder 16 of the explosion-proof cylinder assembly 10 is internally provided with the crumple energy absorbing plate 162, the flame retardant coating 164 and the sound absorbing layer 166, the detonation energy is absorbed through the deformation of the crumple energy absorbing plate 162, and the effects of fire prevention and explosion noise reduction are realized through the flame retardant coating 164 and the sound absorbing layer 166, so that the impact pressure to the lateral direction and the vertical upper direction of the cylinder is greatly reduced, and the risk of explosion injury to operators is effectively reduced.

In an example, the initiating explosive device platform 20 divides the cavity 13 into a first cavity 131 and an explosion venting space 30 along a direction perpendicular to the longitudinal direction of the outer cylinder body 11, the first cavity 131 is arranged above the explosion venting space 30, and the volume of the explosion venting space 30 is larger than that of the first cavity 131. Through constant head tank 22, let out and explode space 30, honeycomb energy-absorbing board 62 and pincher trees energy-absorbing board 162's design, make in the explosive device explosion process, can let out most explosion energy downwards to let out and explode space 30, because let out and explode the enough big more explosion energy that can hold of volume of space 30 and be unlikely to let out to first cavity 131 in, simultaneously because let out and explode the design that has designed multilayer honeycomb energy-absorbing board 62 and pincher trees energy-absorbing board 162 in space 30 and can in time will hold the energy absorption in letting out and explode space 30 fast, thereby effectively reduced the explosion injury risk to operating personnel.

In the embodiment, the detonation energy of the to-be-tested initiating explosive device after the accidental explosion generates impact pressure on the upper part, and part of the initiating explosive device may bounce upwards from the initiating explosive device positioning platform 20 under the reverse thrust action of flame, fuel gas and explosive products, so as to threaten the operators on the upper part. In an embodiment, the initiating explosive device testing explosion proof device 100 can be provided with double protection comprising a first top cover assembly 40 and a second top cover assembly 50 at the upper channel. When an explosion occurs, the pressure relief member 44 first acts as a barrier to the energy of the explosion, absorbing and attenuating it by deforming the deformable cavity 46 in the pressure relief member 44. The first collar 15 circumscribes the first header body 42 and withstands initial detonation impact, is moderately deformable and moderately breakable, but does not break. The second top cap body 52 constitutes a main protection cover, and cooperates with the limit stop 14 to prevent the second top cap body 52 from flying vertically, so as to block the detonation energy in the barrel, and further prevent the operator above from being injured. Meanwhile, the second handle 54 is horizontally placed, so that the rotation of the second top cover body 52 is limited, and the phenomena that the second top cover body 52 rotates and flies out due to uneven stress in the explosion process are prevented, and the second top cover body 52 is restrained at a protection position in the horizontal direction.

Although a few embodiments of the present general inventive concept have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
