Abstract

This invention belongs to the field of electromagnetic transmitters, and specifically relates to a launching method, armature assembly, and launching system. To address the technical problem in existing technologies that cannot deliver cylindrical or non-cylindrical loads with an outer diameter larger than the inner diameter of the coil, this invention proposes a launching method. When the load or launching chamber has a small mass and an irregular shape, such as a cylinder or a tube with an outer diameter larger than the inner diameter of the coil, an adapter is used to fix the load or launching chamber to an outer armature fitted outside the electromagnetic tube. When the load or launching chamber has a large mass, an inner-outer combined armature, consisting of the front ends of an inner armature and an outer armature fixedly connected, is used, and an adapter is used to fix the load or launching chamber to the outer armature. This invention also provides a corresponding launching system and armature assembly. By placing the load outside the electromagnetic tube, the shape and size of the load are not limited by the coil, thereby enabling the launching of loads of various shapes and sizes.

Description

Technical Field

[0001] This invention belongs to the field of electromagnetic transmitters, and in particular relates to a transmitting method, armature assembly, and transmitting system. Background Technology

[0002] When faced with disasters such as fires, earthquakes, and floods, the situation worsens over time. However, during rescue operations, roads are often blocked, preventing rescuers from reaching the affected areas quickly. In such cases, rescuers need to use launching systems to rapidly deliver loads such as fire extinguishers, medical supplies, food, and life jackets to the appropriate locations to minimize the severity of the disaster.

[0003] Currently, for cylindrical loads such as fire extinguishing projectiles with an outer diameter smaller than the inner diameter of the electromagnetic tube containing the coil, an electromagnetic catapult can be used to directly deliver the load to the corresponding location. For example, Chinese invention patents CN109253657B (authorization announcement date: April 2, 2021) and CN105944262A (application publication date: September 21, 2016) both disclose methods for launching an internal armature and load using a coil.

[0004] However, the above-mentioned transmission method cannot deliver loads with an outer diameter larger than the inner diameter of the coil. Summary of the Invention

[0005] The purpose of this invention is to provide a transmitting method, armature assembly, and transmitting system to solve the technical problem in the prior art that loads with an outer diameter larger than the inner diameter of the coil cannot be delivered.

[0006] To achieve the above objectives, the technical solution of the launching method provided by this invention is as follows:

[0007] One launch method involves selecting the following launch method based on the shape and mass of the load or the launch chamber containing the load:

[0008] Method 1: When the mass of the load or transmitter is small and the shape is cylindrical or cylindrical with an outer diameter smaller than the inner diameter of the coil, place the load or transmitter in the electromagnetic tube and place the load or transmitter in front of the inner armature so that the coil drives the inner armature to launch the load or transmitter forward.

[0009] Method 2: When the mass of the load or launch chamber is small and its shape is irregular, cylindrical with an outer diameter larger than the inner diameter of the coil, or cylindrical with an outer diameter larger than the inner diameter of the coil, the load or launch chamber is fixed to the outer armature fitted outside the electromagnetic tube using an adapter, so that the coil drives the outer armature to launch the load or launch chamber forward.

[0010] Method 3: When the load or launch chamber is large, use an adapter to fix the load or launch chamber to the outer armature of the inner-outer combined armature, so that the coil drives the inner-outer combined armature to launch the load or launch chamber forward. The inner-outer combined armature is formed by the front end of the inner armature and the front end of the outer armature being fixedly connected by a connection structure.

[0011] Furthermore, in Method 3, both the inner and outer armatures are located at the front end of the electromagnetic tube, and the connection structure is a connecting ring.

[0012] Furthermore, the connecting ring includes a small-diameter ring, a large-diameter ring, and a connecting rod for connecting the small-diameter ring and the large-diameter ring. The rear end of the large-diameter ring is provided with a large-diameter annular boss whose outer diameter matches the inner diameter of the outer armature. The outer armature and the large-diameter annular boss are interference-fitted to achieve a fixed connection between the outer armature and the connecting structure. The rear end of the small-diameter ring is provided with a small-diameter annular boss whose inner diameter matches the outer diameter of the inner armature. The inner armature and the small-diameter annular boss are interference-fitted to achieve a fixed connection between the inner armature and the outer armature.

[0013] Furthermore, in Method 3, both the inner and outer armatures are located at the rear end of the electromagnetic tube, and the inner and outer armatures are fixedly connected by a "U"-shaped connector.

[0014] The beneficial effects of the launching method provided by this invention are as follows: This invention is a pioneering invention. Utilizing an external armature fitted outside the electromagnetic tube to launch the load or launch chamber allows the shape and size of the load or launch chamber to be unrestricted by the coil. Compared to technical solutions that use a coil to drive either the inner or outer armature separately, when using a coil to simultaneously drive the inner and outer combined armatures, the work done by the coil on the combined armature is greater, resulting in a higher energy level for the combined armature, thus enabling the launch of heavier loads or launch chambers. When launching a load using the launching method of this invention, depending on the shape and mass of the load or the launch chamber containing the load, loads such as fire extinguishers, medical supplies, food, and lifebuoys can be launched to a designated location using appropriate methods.

[0015] To achieve the above objectives, the technical solution for the armature assembly provided by this invention is as follows:

[0016] An armature assembly includes an outer armature for mounting on the outside of an electromagnetic tube having a coil, an adapter being fixedly connected to or integrally formed on the outer peripheral surface of the outer armature, the adapter including a fixing structure for fixing a load or a launch chamber containing a load.

[0017] Furthermore, the armature assembly also includes an inner armature for insertion into the inner cavity of the coil, the inner armature being fixedly connected to or integrally formed with the outer armature, and one axial end of the outer armature and the inner armature having a connection structure for synchronizing the movement of the inner armature and the outer armature.

[0018] Furthermore, the connecting structure includes a small-diameter ring, a large-diameter ring, and a connecting rod for connecting the small-diameter ring and the large-diameter ring. The rear end of the large-diameter ring is provided with a large-diameter annular boss whose outer diameter matches the inner diameter of the outer armature. The outer armature and the large-diameter annular boss are interference-fitted to achieve a fixed connection between the outer armature and the connecting structure. The rear end of the small-diameter ring is provided with a small-diameter annular boss whose inner diameter matches the outer diameter of the inner armature. The inner armature and the small-diameter annular boss are interference-fitted to achieve a fixed connection between the inner armature and the outer armature.

[0019] Furthermore, the connection structure is a "U"-shaped connector. The two ends of the opening of the "U"-shaped connector are fixedly connected to the inner armature and the outer armature, respectively. The side of the "U"-shaped connector away from the opening is used to be located outside the electromagnetic tube during use.

[0020] Furthermore, the fixing structure is a gripper, which is a semi-circular ring; or, the gripper includes two clamping plates and a connecting plate connecting the two clamping plates together, the clamping plates are perpendicular to the connecting plate, and both clamping plates are located on the same side of the connecting plate.

[0021] The beneficial effects of the armature assembly provided by this invention are as follows: This invention is a pioneering creation. The fixed structure can fix the load, so that the fixed load moves synchronously with the external armature. When launching a load using the armature assembly of this invention, the armature assembly is first placed outside the electromagnetic tube, then the load is loaded using the fixed structure, and finally the coil inside the electromagnetic tube is energized. The coil drives the external armature forward, thereby launching the external armature, adapter, and load together. Throughout the launch process, the shape and size of the load are not limited by the coil, thus enabling convenient delivery of loads such as fire extinguishers, medical supplies, food, and lifebuoys.

[0022] To achieve the above objectives, the technical solution of the launching system provided by this invention is as follows:

[0023] A launch system includes a coil, a power supply device for powering the coil, and an armature assembly. The armature assembly includes an outer armature for mounting on an electromagnetic tube containing the coil. An adapter is fixedly connected to or integrally formed on the outer peripheral surface of the outer armature. The adapter includes a fixing structure for fixing a load or a launch chamber containing a load. The coil is used to accelerate the armature assembly.

[0024] Furthermore, the armature assembly also includes an inner armature for insertion into the inner cavity of the coil, the inner armature being fixedly connected to or integrally formed with the outer armature, and one axial end of the outer armature and the inner armature having a connection structure for synchronizing the movement of the inner armature and the outer armature.

[0025] Furthermore, the connecting structure includes a small-diameter ring, a large-diameter ring, and a connecting rod for connecting the small-diameter ring and the large-diameter ring. The rear end of the large-diameter ring is provided with a large-diameter annular boss whose outer diameter matches the inner diameter of the outer armature. The outer armature and the large-diameter annular boss are interference-fitted to achieve a fixed connection between the outer armature and the connecting structure. The rear end of the small-diameter ring is provided with a small-diameter annular boss whose inner diameter matches the outer diameter of the inner armature. The inner armature and the small-diameter annular boss are interference-fitted to achieve a fixed connection between the inner armature and the outer armature.

[0026] Furthermore, the connection structure is a "U"-shaped connector. The two ends of the opening of the "U"-shaped connector are fixedly connected to the inner armature and the outer armature, respectively. The side of the "U"-shaped connector away from the opening is used to be located outside the electromagnetic tube during use.

[0027] Furthermore, the fixing structure is a gripper, which is a semi-circular ring; or, the gripper includes two clamping plates and a connecting plate connecting the two clamping plates together, the clamping plates are perpendicular to the connecting plate, and both clamping plates are located on the same side of the connecting plate.

[0028] The beneficial effects of the launching system provided by this invention are as follows: This invention is an improved invention. The fixing structure can fix the load so that the fixed load moves synchronously with the external armature. When launching a load using the launching system of this invention, firstly, the armature assembly is placed outside the electromagnetic tube, then the load is fixed using the fixing structure, and finally, the coil inside the electromagnetic tube is energized. The coil drives the external armature forward, thereby launching the external armature, adapter, and load together. Throughout the launching process, the shape and size of the load are not limited by the coil, thus enabling convenient delivery of loads such as fire extinguishing bombs, medical supplies, food, and lifebuoys.

[0040] To address the problems in the background art, the core inventive concept of this invention is to place the load outside the electromagnetic tube, so that the shape and size of the load or the launch chamber containing the load are not limited by the coil, thereby enabling the launch of loads of various shapes and sizes.

[0041] The present invention will be further described in detail below with reference to the embodiments.

[0042] Specific embodiments of the launching method provided by this invention:

[0043] Reference Figure 1-9 As shown, launch will be performed in the following manner, depending on the shape and mass of payload 4 or the launch chamber containing payload 4:

[0044] Method 1, such as Figure 2 As shown, when the mass of the load 4 or the launch chamber is small and the shape is a cylinder or cylindrical shape with an outer diameter smaller than the inner diameter of the coil 1, the load 4 or the launch chamber is placed in the electromagnetic tube and the load 4 or the launch chamber is placed in front of the inner armature 6 so that the inner armature 6 is driven by the coil 1 to launch the load 4 or the launch chamber forward.

[0045] Method 2: When the mass of the load 4 or the launch chamber is small and the shape is irregular, cylindrical with an outer diameter larger than the inner diameter of the coil, or cylindrical with an outer diameter larger than the inner diameter of the coil, the load 4 or the launch chamber is fixed on the outer armature 2 that is sleeved outside the electromagnetic tube using the adapter 3, so that the coil 1 drives the outer armature 2 to launch the load 4 or the launch chamber forward.

[0046] Method 3: When the mass of the load 4 or the launch chamber is large, the front end of the inner armature 6 and the front end of the outer armature 2 are fixedly connected by the connection structure 5 to form an inner-outer combined armature. The load 4 or the launch chamber is fixed on the outer armature 2 in the inner-outer combined armature by the adapter 3, so that the inner-outer combined armature is driven by the coil 1 to launch the load 4 or the launch chamber forward.

[0047] Among them, reference Figure 1-2 As shown, when the load 4 is a cylindrical load 4 that can be placed inside the electromagnetic tube, the load 4 can be launched using the inner armature 6 (i.e., mode one) or the load 4 can be launched using the outer armature 2 (i.e., mode two). That is, all loads 4, including the cylindrical load 4, can be launched using the outer armature 2. However, from the perspective of launch convenience, it is more convenient to place the load 4 directly inside the electromagnetic tube and launch the load using the inner armature 6.

[0048] When launching load 4, each armature is launched along with load 4, meaning each armature is a disposable projectile armature. Therefore, multiple external armatures 2 and corresponding adapters 3 need to be prepared. When preparing external armatures 2 and adapters 3, various different adapters 3 can be prepared as needed, so that loads 4 or launch chambers of various shapes and sizes can be launched using the same electromagnetic catapult.

[0049] The load 4 is launched using an external armature 2 fitted outside the electromagnetic tube, allowing the shape and size of the load 4 or launch chamber to be unrestricted by the coil 1. After the load 4 is fixedly connected to the external armature 2 using the adapter 3, the coil 1 is energized, driving the external armature 2 forward to launch the external armature 2, adapter 3, and load 4 together. When launching the load 4 using the launching method of this invention, the shape and size of the load 4 or launch chamber are not restricted by the coil 1, thus enabling the convenient delivery of loads 4 such as fire extinguishing bombs, medical supplies, food, and lifebuoys.

[0050] As one specific implementation method, such as Figure 1-9 As shown, the adapter 3 has a clamp 31, and the load 4 is interference-fitted into the clamp 31, which makes it easy to fix the load 4 on the clamp 31. At the same time, when the load 4 is medical supplies or food, people in the disaster area can also separate the load 4 from the adapter 3 without the aid of tools.

[0051] The launch chamber can be a box, tank, or other structure. When launching payloads 4 such as medicine or clothing, the payload 4 can be loaded into the launch chamber first, and then the launch chamber can be launched directly. The launch chamber can be filled with shock-absorbing structures such as sponge or foam paper to prevent damage to the payload 4 during landing. During launch, because the payload 4 will also cut magnetic field lines, when launching payloads 4 such as liquids with conductive ions or precision instruments, the launch chamber must be made of metal to achieve electrostatic shielding of the objects inside. The launch chamber can also be fixedly connected to the external armature 2 by welding, snap-fitting, or flange connection. After the payload 4 is delivered to the disaster area, the people in the disaster area can open the launch chamber and retrieve medical supplies or food.

[0052] like Figure 3-6 As shown, in one specific embodiment, in mode three, both the inner armature 6 and the outer armature 2 are located at the front end of the electromagnetic tube (including the coil 1 and the gun steel for supporting the coil 1), and the connecting structure 5 is a connecting ring, which is simple in structure.

[0053] The connecting ring includes a small-diameter ring 54, a large-diameter ring 53, and a connecting rod 55 for connecting the small-diameter ring 54 and the large-diameter ring 53. The rear end of the large-diameter ring 53 has a large-diameter annular boss 51 whose outer diameter matches the inner diameter of the outer armature 2. The outer armature 2 is interference-fitted with the large-diameter annular boss 51 to achieve a fixed connection between the outer armature 2 and the connecting structure 5. The rear end of the small-diameter ring 54 has a small-diameter annular boss 52 whose inner diameter matches the outer diameter of the inner armature 6. The inner armature 6 is interference-fitted with the small-diameter annular boss 52 to achieve a fixed connection between the inner armature 6 and the outer armature 2. On the one hand, the inner armature 6, the outer armature 2, and the connecting structure 5 can be transported separately; on the other hand, when launching the load 4 in the field, a single outer armature 2, a single inner armature 6, or an integrated inner armature 6 and outer armature 2 can be used according to actual needs, making field management more flexible. However, in other specific embodiments, the inner armature 6 and the outer armature 2 can also be integrally injection molded, with the front end of the inner armature 6 and the front end of the outer armature 2 connected by a connecting rod 55. In this case, a sufficient number of armature assemblies (including the inner armature 6 and the outer armature 2) need to be prepared to avoid the discovery of insufficient armature assemblies during field launch.

[0054] In this invention, the external armature 2 and the adapter 3 can be integrally formed; alternatively, the external armature 2, the internal armature 6, the connecting structure 5, and the adapter 3 can all be separate parts, which are then assembled on-site using methods such as welding, plugging, pinning, or interference fit to form an armature assembly. Compared to the assembled armature assembly, the individual parts are easier to stack together during transportation, occupy less space, and are more convenient to transport.

[0055] like Figure 7As shown, in one specific embodiment, in method three, the connection structure is a "U"-shaped connector. Both the inner armature 6 and the outer armature 2 are located at the rear end of the electromagnetic tube, and are fixedly connected by the "U"-shaped connector. The two ends of the opening of the "U"-shaped connector are fixedly connected to the inner armature 6 and the outer armature 2, respectively. The side of the "U"-shaped connector furthest from the opening is located outside the electromagnetic tube during use to avoid interference between the "U"-shaped connector and the electromagnetic tube. In this case, the inner armature 6 and the outer armature 2 are accelerated over a longer distance, which is beneficial for increasing the initial velocity of the inner-outer combined armature.

[0056] Specific embodiments of the launching system provided by the present invention:

[0057] The launching system in this embodiment can launch the payload using the launching method of the present invention.

[0058] like Figure 1-9 As shown, the launch system includes an electromagnetic tube with a coil 1, a power supply device for supplying power to the coil 1, and an armature assembly. The armature assembly includes an outer armature 2 for fitting around the electromagnetic tube. An adapter 3 is fixedly connected to or integrally formed on the outer circumference of the outer armature 2. The adapter 3 includes a fixing structure for fixing a load 4 or a launch chamber containing the load 4, specifically a gripper 31, a fixing flange, a welding surface, etc. The coil 1 is used to accelerate the armature assembly. The launch system also includes a pitch adjustment seat for adjusting the pitch angle of the electromagnetic tube and a horizontal adjustment seat for adjusting the horizontal orientation of the electromagnetic tube, thereby adjusting the launch angle.

[0059] The fixing structure can fix the load 4 so that the fixed load 4 moves synchronously with the external armature 2. When launching the load 4 using the launching system of this invention, the armature assembly is first placed over the electromagnetic tube, then the fixed structure is used to fix the load 4 or the launch chamber, and finally the coil 1 inside the electromagnetic tube is energized. The coil 1 drives the external armature 2 forward, thereby launching the external armature 2, the adapter 3, and the load 4 together. Throughout the launching process, the shape and size of the load 4 and / or the launch chamber are not limited by the coil 1, thus enabling the convenient delivery of loads 4 such as fire extinguishing bombs, medical supplies, food, and lifebuoys.

[0060] To better secure the load 4, at least two adapters 3 are arranged at intervals along the axial direction of the external armature 2. Figure 3 Specifically, there may be two adapters 3 (but there could also be three or more), and all adapters 3 are used to simultaneously fix the same load 4. Of course, in other specific embodiments, only one adapter 3 may be used to fix the load 4.

[0061] like Figure 3-6As shown, in order to enable the launching system to launch a heavier load 4, in one specific embodiment, the armature assembly also includes an inner armature 6 for insertion into the inner cavity of the coil 1. The inner armature 6 is fixedly connected to or integrally formed with the outer armature 2. One axial end of the outer armature 2 and the inner armature 6 has a connecting structure 5 for synchronizing the movement of the inner armature 6 and the outer armature 2, thereby enabling the coil 1 to apply greater work to the armature assembly, ensuring that the armature assembly can carry a heavier load 4 to the designated position.

[0062] In one specific implementation, such as Figure 3-6 As shown, the connecting structure 5 includes a small-diameter ring 54, a large-diameter ring 53, and a connecting rod 55 for connecting the small-diameter ring 54 and the large-diameter ring 53. The rear end of the large-diameter ring 53 has a large-diameter annular boss 51 whose outer diameter matches the inner diameter of the outer armature 2. The outer armature 2 is interference-fitted with the large-diameter annular boss 51 to achieve a fixed connection between the outer armature 2 and the connecting structure 5. The rear end of the small-diameter ring 54 has a small-diameter annular boss 52 whose inner diameter matches the outer diameter of the inner armature 6. The inner armature 6 is interference-fitted with the small-diameter annular boss 52 to achieve a fixed connection between the inner armature 6 and the outer armature 2. The structure is simple and easy to assemble. In use, the inner armature 6 and the outer armature 2 are located at the front end of the electromagnetic tube.

[0063] In one specific implementation, such as Figure 7 As shown, the connecting structure 5 is a "U"-shaped connector. The two ends of the opening of the "U"-shaped connector are fixedly connected to the inner armature 6 and the outer armature 2, respectively. The side of the "U"-shaped connector away from the opening is used to be located outside the electromagnetic body tube during use. During use, the inner armature 6 and the outer armature 2 are accelerated over a longer distance, and the inner-outer combined armature has a greater initial velocity.

[0064] In different specific embodiments, the inner armature 6, the outer armature 2, and the connecting structure 5 can also be fixedly connected by welding, pinning, or other methods; or, the inner armature 6, the outer armature 2, and the connecting structure 5 can be integrally injection molded.

[0065] In one embodiment, the gripper 31 is a semi-circular ring to facilitate gripping a cylindrical load 4. In another embodiment, the gripper 31 includes two clamping plates and a connecting plate connecting the two clamping plates together. The clamping plates are perpendicular to the connecting plate, and both clamping plates are located on the same side of the connecting plate to facilitate gripping a cuboid load 4. Of course, if needed, the two clamping plates may not be perpendicular to the connecting plate, but rather the angle between them and the connecting plate may be acute, forming a tapered structure to accommodate a load 4 with a trapezoidal cross-section. Different adapters 3 can be manufactured as needed depending on the different loads 4, which will not be elaborated here.

[0066] Specific embodiments of the armature assembly provided by the present invention:

[0067] The specific structure of the armature assembly in this embodiment is the same as that of the armature assembly in the specific embodiment of the launch system of the present invention, and will not be described again here.

[0068] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
