Description

Technical Field

[0001] The invention relates to a scattering device, in particular to a push plate type scattering device with changeable fire transmission and directional scattering, belonging to the technical field of pyrotechnic devices, and mainly suitable for scattering aerial submunition bullets mounted on unmanned aerial vehicles. Background Art

[0002] With the rapid development of military technology, my country's position in the world's military powers has been continuously improved, especially in the field of drones, which has achieved major technological breakthroughs. At the same time, it has also brought about the blowout development of drone-mounted aerial submunitions, and the submunition scattering technology of various complex structures of aerial submunitions has ushered in rapid development. In the background technology, the existing domestic submunition scattering methods mainly include airbag-type flexible work and piston-type work. The airbag-type flexible work scattering method is mainly used for the scattering of multiple submunitions in the circumferential direction with sufficient space inside the aerial submunition, while the piston-type work scattering method is generally suitable for scattering with large space and no special requirements for overload, and is not suitable for scattering with tight space and low overload. With the diversified development of the structure, function and combat mission of aerial cluster bombs, especially in the new intelligent aerial ammunition, due to its complex structure and tight space, both the airbag-type flexible working scattering method and the piston-type working scattering method will have obvious limitations in design and process. In order to solve the shortcomings of the existing scattering technology and meet the needs of diversified and intelligent development of aerial cluster bombs, we have developed a push-plate scattering device. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a push-plate type scattering device, which adopts a reverse air-tight one-way fire transfer structure, a change-of-direction fire transfer channel, a small gas generator and directional scattering and other technical designs. By doing work with a push plate, the directional scattering of sub-munitions is achieved while meeting the complex and tight space structure.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A push plate type scattering device, comprising a fire receiving component, a front end plate, a sealing screw, a fire transmission component, a gas generator, a push plate, a body, a pin seat, a tightening screw, and a rear end plate;

[0006] The fire connection component includes a buckle cap, a silk pad I, lead styphenate, a fire connection powder I, a three-hole spacer, a fire connection powder II, a fire connection shell, and a silk pad II. The fire connection component receives the flame energy output by the external upper-level pyrotechnic product, instantly ignites its own fire connection powder I and fire connection powder II, and realizes reliable fire connection;

[0007] The front end plate is a connecting structural member of the scattering device, and the fire receiving component and the fire transmission component are respectively screwed on the center screw hole on the upper end surface and the outer screw hole on the lower end surface of the front end plate after being coated with glue.

[0008] The sealing screw thread is coated with glue and then screwed into the screw hole on the outside of the front end plate;

[0009] The fire transmission component includes input lead styphenate, fire transmission powder I, silk pad III, silk pad IV, reinforcement cap, fire transmission tube shell, hollow powder column, silk pad V, fire transmission seat, black powder column, fire transmission powder II, silk pad VI, the fire transmission component receives the flame energy output by the fire receiving component, and ignites its own fire transmission powder I, hollow powder column, black powder column, and fire transmission powder II in sequence, and the flame energy generated by the fire transmission component is output to the gas generator;

[0010] The gas generator comprises a gas generating agent, a gas generating agent tube, a sealing pressure ring, a sealing film I, an exhaust pipe, and a sealing film II. The threads of the output end of the flame transmission component are coated with glue and connected to the gas generator. The threads of the gas generator are coated with glue and screwed onto the output end of the flame transmission component. The gas generator receives the flame energy output by the flame transmission component and ignites its own gas generating agent. The combustion of the gas generating agent generates a large amount of high-temperature gas which is filled into the sealed cavity.

[0011] The push plate is plug-connected to the body, and the push plate and the body form an initial sealed cavity. A large amount of high-temperature gas generated by the gas generator is filled into the sealed cavity, and the expansion work pushes the push plate to move quickly, releases the restraint of the sub-munition band, and instantly pushes out the sub-munition;

[0012] The two ends of the body are connected to the front plate and the rear plate respectively by a plurality of bolts;

[0013] The pin seat fixes the sub-munitions through the band and the pin;

[0014] The tightening screw is installed in the stepped hole of the rear end plate, and the front end thread of the tightening screw is glued and screwed to the exhaust pipe of the gas generator to fix the gas generator;

[0015] The rear end plate is connected to the lower end of the body through a plurality of bolts.

[0016] Furthermore, the three-hole spacer included in the fire connection component has a uniformly distributed hole spacing, and the three-hole spacer is installed at the step of the central cylindrical hole inside the fire connection shell. When the fire connection powder II of the fire connection component burns, its reaction force pushes the three-hole spacer to the step of the central hole, so that the fire connection powder II burns and forms a flame to transmit fire along the specified output direction, realizing the reverse air-tight one-way fire transmission function;

[0017] Furthermore, the front end plate is internally designed with a fire transmission channel connecting the fire receiving component and the fire transmission component, the fire transmission channel is perpendicular to the fire receiving component and the fire transmission component, and can realize the effective transmission of the flame energy output by the fire receiving component to the fire transmission component in a redirected manner, and the flame energy output by the fire receiving component is reasonably designed according to the length of the fire transmission channel;

[0018] Furthermore, the push plate is a U-shaped groove structure, and the outer sides of the edges of the two side walls of the U-shaped groove of the push plate are designed with longitudinal V-shaped grooves;

[0019] Furthermore, the body is a U-shaped groove structure, and the inner side wall of the U-shaped groove of the body is designed with a longitudinal through-length V-shaped convex groove;

[0020] Furthermore, the size and shape of the V-shaped groove of the push plate are completely consistent with the V-shaped convex groove of the main body. The push plate and the main body are connected by longitudinally matching the V-shaped concave and convex grooves to form an initial sealed cavity. The main body directionally constrains the push plate through the V-shaped concave and convex grooves.

[0021] The beneficial effects of the present invention compared with the background technology are as follows:

[0022] 1. The present invention adopts the reverse air-tight one-way fire transmission structure, the changeable fire transmission channel, the small gas generator and the directional dispersion and other technical designs, which can effectively increase the loading space of sub-munitions and solve the problem of loading sub-munitions in asymmetric compact space. By pushing the plate to do work, the safe and reliable directional dispersion of sub-munitions can be achieved while meeting the complex space structure;

[0023] 2. The push plate and the body of the present invention adopt a V-shaped concave-convex groove structure design, and the push plate and the body form an initial sealed cavity. The body directional constrains the push plate 6 through the V-shaped concave-convex groove, which can ensure that the push plate releases the hoop constraint of the sub-munition along the constraint direction and instantly pushes out the sub-munition;

[0024] 3. It has the advantages of reasonable structural design, safe and reliable use, high energy utilization, low scattering overload, high scattering speed and suitability for mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings:

[0037] like Figure 1 As shown, a push plate type throwing device comprises: a fire receiving component 1, a front end plate 2, a sealing screw 3, a fire transmission component 4, a gas generator 5, a push plate 6, a body 7, a pin seat 8, a tightening screw 9, and a rear end plate 10;

[0038] The threads of the fire receiving component 1 and the fire transmitting component 4 are respectively screwed into the central screw hole on the upper end face and the outer screw hole on the lower end face of the front end plate 2 after being coated with glue;

[0039] The sealing screw 3 is coated with glue on its thread and then screwed into the screw hole on the outer side of the front end plate 2;

[0040] The upper thread of the gas generator 5 is coated with glue and then screwed onto the output end of the flame transmission component 4;

[0041] The push plate 6 is connected to the body 7 by longitudinally fitting and plugging through a V-shaped groove;

[0042] Both ends of the body 7 are connected to the front end plate 2 and the rear end plate 10 respectively by a plurality of bolts;

[0043] The pin seat 8 fixes the bullet through the band and the pin;

[0044] The tensioning screw 9 is installed in the stepped hole of the rear end plate 10, and the front end thread of the tensioning screw 9 is glued and screwed to the gas generator 5 to fix the gas generator 5;

[0045] The rear end plate 10 is connected to the lower end of the body 7 by a plurality of bolts.

[0046] like Figure 2 As shown, the fire receiving component 1 includes a reverse buckle cap 11, a silk pad Ⅰ 12, lead stevenate 13, a fire receiving powder Ⅰ 14, a three-hole spacer 15, a fire receiving powder Ⅱ 16, a fire receiving shell 17, and a silk pad Ⅱ 18;

[0047] The buckle cap 11, the silk pad I 12, the lead stevenate 13, the gunpowder I 14, the three-hole spacer 15, the gunpowder II 16, and the silk pad II 18 are sequentially installed in the central cylindrical hole inside the gunpowder shell 17;

[0048] The fire connection component 1 receives the flame energy input from the external upper-level pyrotechnics, and instantly ignites its own fire connection powder I 14 and fire connection powder II 16, thus achieving effective fire connection;

[0049] The three-hole spacer 15 is installed at the step of the central cylindrical hole inside the fire receiving shell 17. When the fire receiving powder II 16 of the fire receiving component 1 burns, its reaction force pushes the three-hole spacer to the step of the central hole, so that the burning flame of the fire receiving powder II is formed and the fire is transmitted along the specified output direction, realizing the reverse air-tight one-way fire transmission function;

[0050] The silk pads I 12 and II 18 isolate the gunpowder receiving device from the outside world to avoid electrostatic interference.

[0051] like Figure 3 As shown, the front end plate 2 is an important connecting structural member of the scattering device, and a fire transfer channel connecting the fire receiving component 1 and the fire transfer component 4 is designed inside the front end plate 2;

[0052] The fire transmission channel is perpendicular to the fire receiving component 1 and the fire transmission component 4, and can realize the one-way effective transmission of the flame energy output by the fire receiving component 1 to the fire transmission component 4;

[0053] The flame energy output of the fire receiving component is reasonably designed according to the length of the fire transmission channel. The fire transmission channel realizes the transformation of central input ignition into lateral output ignition, changes the direction of the fire transmission channel, meets the loading requirements of sub-munitions, and meets the special structural requirements of the scattering device for single-side loading of sub-munitions through the space design of small space and special-shaped structure.

[0054] like Figure 4As shown, the fire transmission component 4 includes input lead styphenate 19, fire transmission powder I 20, silk pad III 21, silk pad IV 22, reinforcing cap 23, fire transmission tube shell 24, hollow powder column 25, silk pad V 26, fire transmission seat 27, black powder column 28, fire transmission powder II 29, silk pad VI 30;

[0055] Input lead styphenate 19, explosive powder I 20, silk pad III 21, silk pad IV 22, reinforcing cap 23, explosive tube shell 24, hollow powder column 25, silk pad V 26, black powder column 28, explosive powder II 29, silk pad VI 30 and install them in the central cylindrical hole inside the explosive seat 27 in sequence;

[0056] The fire transmission component 4 receives the flame energy output by the fire receiving component 1 through the fire transmission channel of the front end plate 2, and sequentially ignites its own fire transmission powder I 20, hollow powder column 25, black powder column 28, and fire transmission powder II 29. The flame energy generated by the fire transmission component 4 is output to the gas generator 5.

[0057] The silk pads III 21, IV 22, V 26 and VI 30 isolate the gunpowder from the outside world to avoid electrostatic interference.

[0058] like Figure 5 As shown, the gas generator 5 includes a gas generating agent 31, a gas generating agent tube 32, a sealing pressure ring 33, a sealing film I 34, an exhaust pipe 35, and a sealing film II 36;

[0059] The gas generating agent 31 is filled in the gas generating agent tube 32;

[0060] The exhaust pipe 35 is threadedly installed on the lower end of the gas producing medicine tube 32 after being coated with glue. A sealing pressure ring 33 and a sealing film I 34 are installed between the gas producing medicine tube 32 and the exhaust pipe 35.

[0061] The sealing film I 34 and the sealing film II 36 seal the gas producing medicine pipe 32 and the exhaust pipe 35 respectively;

[0062] The gas generator 5 receives the flame energy from the flame transmission component 4 and ignites its own gas generating agent 31. The gas generating agent 31 burns rapidly to generate a large amount of high-temperature gas. After breaking the membrane, the high-temperature gas flows through the exhaust pipe 35 and is filled into the push plate sealing cavity through the exhaust hole of the exhaust pipe 35.

[0063] like Figure 6 As shown, the push plate 6 is a U-shaped groove structure, and the outer sides of the edges of the two side walls of the U-shaped groove of the push plate 6 are designed with longitudinal full-length V-shaped grooves.

[0064] like Figure 7 As shown, the body 7 is a U-shaped groove structure, and the inner side wall of the U-shaped groove of the body 7 is designed with a longitudinal through-length V-shaped convex groove;

[0065] The size and shape of the V-shaped groove of the push plate 6 and the V-shaped convex groove of the body 7 are completely consistent.

[0066] like Figure 8 As shown, the push plate 6 and the body 7 are connected by longitudinally fitting through the V-shaped concave-convex groove to form an initial sealed cavity. At the same time, the body 7 directional constrains the push plate 6 through the V-shaped concave-convex groove. A large amount of high-temperature gas generated by the gas generator 5 is filled into the sealed cavity. The high-temperature gas expands and does work to push the push plate 6 to move quickly. The push plate 6 breaks away from the restriction of the V-shaped concave-convex groove, releases the constraint of the sub-munition hoop, and instantly pushes out the sub-munition.

[0067] The embodiment described above is only a specific embodiment of the present invention and does not limit the present invention in any form. All other embodiments obtained by changes, modifications, substitutions or variations based on the technical solution of the present invention by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
