[0052] Example 1

[0053] One specific embodiment of the present invention discloses an electromagnetic launch system, such as... Figure 1-15 As shown, it includes: a launch turret, an electromagnetic transmitter 6, and a detection device 58.

[0054] The launch turret includes a pitch transmission mechanism 3 and an azimuth transmission mechanism 4, which can adjust the azimuth and pitch angles of the launch turret's cradle 5.

[0055] The electromagnetic transmitter 6 is mounted on the cradle 5 of the launching turret and can launch electromagnetically at the load 7, which can be a fire extinguishing bomb, smoke bomb, or explosive bomb.

[0056] The detection device 58 includes: a zoomable visible light camera, a fixed-focus visible light camera, an infrared camera, and a laser rangefinder; the zoomable visible light camera, the fixed-focus visible light camera, and the infrared camera are used to detect the target position, and the laser rangefinder is used to detect the distance between the target position and the launch point. After determining the target position, the launch speed of the load is then determined, enabling the load to be accurately launched to the target position.

[0057] The azimuth measuring assembly 25 and the elevation measuring assembly 26 are used; the detection device 58 is used to detect the target position, which can be the ignition point, explosion point, etc., depending on the actual needs. The azimuth measuring assembly 25 and the elevation measuring assembly 26 can monitor the azimuth and elevation angles of the cradle 5 in real time, thereby realizing the adjustment of the elevation and azimuth angles when the electromagnetic transmitter 6 launches the load.

[0058] like Figure 16As shown, during implementation, the detection device 58 detects the target position, the pitch transmission structure 3 and the azimuth transmission mechanism 4 drive the rocker arm 5 to rotate, thereby adjusting the angle of the detection device 58 and the electromagnetic transmitter 6; the detection direction of the detection device 58 is adjusted by rotating the transmission turret, so that the target appears in the field of view of the zoom visible light camera, the zoom control module controls the magnification of the zoom visible light camera, and the target being aimed is centered on the display screen; the position of the transmission turret is adjusted according to the dynamic changes of the target position to achieve target tracking and positioning, and after the electromagnetic transmitter 6 aims at the target, the load 7 is launched.

[0059] (1) Launch turret

[0060] In one specific embodiment of the present invention, the launch turret includes: a base 1, a turntable 2, a pitch transmission mechanism 3, an azimuth transmission mechanism 4, and a cradle 5. The turntable 2 is rotatably mounted on the base 1, and the azimuth transmission mechanism 4 drives the turntable 2 to rotate circumferentially relative to the base 1; the cradle 5 is mounted on the turntable 2 via the pitch transmission mechanism 3, and the pitch transmission mechanism 3 drives the cradle 5 to pitch; the cradle 5 is used to mount the launcher 6; an anti-recoil device 59 is provided on the cradle 5; the launcher 6 is slidably mounted on the cradle 5, and the launcher 6 is connected to the anti-recoil device 59.

[0061] like Figure 1-9 As shown, the turntable 2 is mounted above the base 1. The azimuth transmission mechanism 4 is fixedly connected to the turntable 2 by bolts. The rear sides of the cradle 5 are hinged to the two support arms 23 on the upper part of the turntable 2. One end of the pitch transmission mechanism 3 is hinged to the middle of the turntable 2, and the other end is hinged to the front of the cradle 5. The launcher 6 is connected to the cradle 5 via the guide rail 57 and the anti-recoil device 59.

[0062] In one specific embodiment of the present invention, the base 1 includes: a base 11, a buffer bracket 12, a buffer 13, and a stiffening plate 14; as shown Figure 3 As shown, the stiffening plate 14 is welded to the base 11, the buffer bracket 12 is bolted to the base 11, and the buffer 13 is fixedly connected to the buffer bracket 12 by a round nut. The main function of the base 1 is to provide an installation reference for the launching device, and it also has the function of azimuth buffering and stopping.

[0063] In one specific embodiment of the present invention, such as Figure 4 As shown, the turntable 2 includes: a turntable bearing 21, a support platform 22, a support arm 23, a baffle 24, an azimuth angle measuring assembly 25, a pitch angle measuring assembly 26, and a cable mounting plate 27. The turntable 2 serves to support the cradle 5 and also has the function of azimuth rotation.

[0064] Specifically, the support platform 22 is rotatably mounted on the base 1 via a slewing bearing 21; the lower surface of the slewing bearing 21 is bolted to the base 1, and the upper surface of the slewing bearing 21 is bolted to the support platform 22. The function of the slewing bearing 21 is to provide rotational support. Two left and right support arms 23 are located on either side of the circular support platform 22, and the support arms 23 are fixedly connected to the support platform 22 via bolts. The baffle 24 is fixedly connected to the support platform 22 via bolts. Figure 4 As shown, the baffle 24 has a semi-enclosed structure, with its lower end protruding from the lower surface of the turntable 2. When the turntable 2 rotates circumferentially, the baffle 24 can contact the buffer 13. The baffle 24 cooperates with the buffer 13 on the base 1 to achieve the purpose of azimuth rotation stop, increasing the safety of azimuth movement.

[0065] Specifically, the azimuth measuring assembly 25 is located at the left front of the turntable and is threadedly connected to the support platform 22. The azimuth measuring assembly 25 includes a measuring gear and an encoder. The measuring gear meshes with the turntable bearing 21, and the encoder is used to monitor the number of rotations of the measuring gear, thereby determining the rotation angle of the turntable bearing 21. Furthermore, the azimuth measuring assembly 25 acquires the rotation angle in real time and feeds it back to the control center to facilitate azimuth tracking of the target.

[0066] Specifically, the pitch angle measuring assembly 26 is installed at the hinge shaft hole between the support arm 23 and the rocker arm 51. The function of the pitch angle measuring assembly 26 is to acquire the pitch angle in real time and feed it back to the control center to facilitate target pitch tracking. The pitch angle measuring assembly 26 is an angle sensor used to monitor the pitch angle of the rocker arm 51. For example, the pitch angle measuring assembly 26 is an angle sensor used to monitor the angle change between the rocker arm 51 and the support arm 23.

[0067] The cable mounting plate 27 is used to connect the power cables of each component and the central controller.

[0068] In one specific embodiment of the present invention, such as Figure 5 As shown, the pitch transmission mechanism 3 includes: an electric cylinder 31, an upper support lug 32, a lower support lug 33, and a positioning pin 34.

[0069] Specifically, the upper support lug 32 is welded to the rocker arm 51 of the cradle 5, and the lower support lug 33 is welded and fixed to the support platform 22 of the turntable 2. One end of the electric cylinder 31 is rotatably connected to the upper support lug 32 via a positioning pin 34, and the other end is connected to the lower support lug 33 via a positioning pin 34. In this invention, the electric cylinder 31, the support arm 23, and the rocker arm 51 form a triangular structure. When the electric cylinder 31 extends or retracts, the electric cylinder 31 and the rocker arm 51 deflect synchronously. The extension and retraction of the electric cylinder 31 can realize the pitch movement of the cradle 5, thereby realizing the pitch movement of the launcher 6 and adjusting the launch angle.

[0070] One end of the rocker arm 51 is hinged to the electric cylinder 31, and the other end is hinged to the upper end of the support arm 23; when the electric cylinder 31 outputs linear displacement, the rocker arm 51 undergoes pitching motion.

[0071] In one specific embodiment of the present invention, such as Figure 6 As shown, the orientation transmission mechanism 4 includes: a servo motor 41, a reducer 42, a pinion 43, and a cover 44.

[0072] Specifically, the servo motor 41 is used to output rotary motion. The reducer 42 is fixed to the support platform 22 by bolts. The output shaft of the servo motor 41 is fixedly connected to the input shaft of the reducer 42, and a pinion 43 is fixedly mounted on the output shaft end of the reducer 42.

[0073] Specifically, the pinion 43 meshes with the turntable bearing 21. A meshing gear ring is provided on the inner ring side of the turntable bearing 21, which can mesh and transmit power with the pinion 43. When the pinion 43 rotates, the inner ring of the turntable bearing 21 drives the support platform 22 to rotate synchronously. The rotation of the pinion 43 can drive the support platform 22 to rotate via the turntable bearing 21. The servo motor 41 is the power source for the azimuth movement of the transmitter 6; precise control of the azimuth movement of the transmitter 6 can be achieved by controlling the servo motor.

[0074] Furthermore, the rocker arm 51 is connected to the pitch transmission mechanism 3; it can pitch under the drive of the pitch transmission mechanism. The upper sleeve 52 and the lower sleeve 53 are both fixedly installed on the rocker arm 51, and the upper sleeve 52 and the lower sleeve 53 are symmetrically arranged; the transmitter 6 passes through the front sleeve 54 and is fixed between the upper sleeve 52 and the lower sleeve 53; and the transmitter 6 is slidably engaged with the guide rail 57.

[0075] In one specific embodiment of the present invention, such as Figure 7 , Figure 8 As shown, the cradle 5 includes: a rocker arm 51, an upper sleeve 52, a lower sleeve 53, a front sleeve 54, an upper support plate 55, a lower support plate 56, a guide rail 57, and a recoil mechanism 59. The function of the cradle 5 is to support the transmitter 6 and simultaneously withstand the recoil force generated by electromagnetic emission.

[0076] Specifically, the upper sleeve 52, lower sleeve 53, front sleeve 54, upper support plate 55, lower support plate 56, and guide rail are symmetrically distributed along the center line of the rocker arm 51.

[0077] Specifically, the lower sleeve 53 is located at the lower rear of the rocker arm 51, and the lower support plate 56 is located below the front of the rocker arm 51. The lower sleeve 53 and the lower support plate 56 are fixedly connected to the lower part of the rocker arm 51 by welding. The upper sleeve 52, the upper support plate 55, and the front sleeve 54 are sequentially fixed to the upper part of the rocker arm 51 from back to front by screw connections.

[0078] Specifically, such as Figure 9 As shown, L-shaped guide rails 57 are welded to the inner side of rocker arms 51. There are four sections of guide rails 57, arranged in two sets on the rocker arms 51 on both sides, with two sections of guide rails 57 symmetrically arranged in each set. The four sections of guide rails 57, together with the upper sleeve 52 and the front sleeve 54, form a slide, allowing the launcher 6 to be clamped and fixed within the slide, and enabling the launcher to move within the slide under recoil.

[0079] In one specific embodiment of the present invention, the cradle 5 is further provided with a detection device 58.

[0080] Furthermore, the detection device 58 is bolted to the upper support plate 55. The function of the detection device 58 is to detect the target and feed the target back to the control system. The control system issues instructions based on the target data to drive the launch device to complete the launch mission.

[0081] (2) Electromagnetic transmitter

[0082] Electromagnetic transmitting devices, such as Figure 10 The diagram shows: a guidance section 61, an acceleration section 62, and a recoil section 63.

[0083] The acceleration section 62 includes: a drive coil 625, a reinforcing frame, and a transmitting armature 66; the reinforcing frame is disposed outside the drive coil 625; the transmitting armature 66 is disposed inside the drive coil 625, and the transmitting armature 66 is capable of linear displacement along the axis of the drive coil 625 under the action of the electromagnetic force generated by the drive coil 625; the transmitting armature 66 is used to provide the driving force for the load 7 to be launched; the guiding section 61 is used to guide the load 7 to the exit posture.

[0084] Guide Section 61:

[0085] Specifically, the guidance section includes a guide tube and a front support 611. The guide tube is a cylindrical structure used to ensure the attitude of the load 7 (e.g., a fire extinguishing bomb) when it exits the tube. The guide tube is made of a high-strength non-metallic material to ensure that no induced eddy currents are generated in the guide tube under the strong magnetic field environment during launch. The front support 611 is a flat plate structure protruding from the guide tube and is fixedly connected to the guide tube. The front support 611 provides support for the entire electromagnetic launch device. To ensure strength, the support assembly is made of metallic material. The guidance section 61 and the acceleration section 62 are connected by a flange, on which bolts and pins are installed for the connection.

[0086] Acceleration Segment 62:

[0087] Specifically, such as Figure 11 , Figure 12 As shown, the acceleration section 62 includes: a reinforcing frame, a drive coil 625, a cable connector 627, a positioning cylinder 64, and a positioning sensor 65.

[0088] The drive coil 625 has five stages, that is, five drive coils 625 are arranged in parallel to provide the driving force required for electromagnetic emission. Furthermore, cable connectors 627 are provided on the outside of the drive coils 625, with each stage of drive coil 625 having one cable connector 627. The cable connectors 627 are connected to the power supply via coaxial cables. Furthermore, insulation treatment should be applied at the cable connectors 627, and the number of cable connectors 627 corresponds to the number of drive coils 625.

[0089] Specifically, the reinforcing frame is used to radially constrain the drive coil 625.

[0090] Based on the emission principle of the drive coil, the drive coil 625 generates electromagnetic eddy currents, which drive the internal transmitting armature 66 to move along the axis of the drive coil 625 via electromagnetic force. The drive coil 625 is connected to a pulse capacitor, and the discharge of the capacitor in the control circuit is controlled by an independent trigger switch. The transient current flowing through the drive coil 625 induces a transient magnetic field in the inner cavity, which in turn induces eddy currents on the surface and inside the transmitting armature 66. Because the eddy currents are subjected to the Lorentz force in the changing magnetic field, the transmitting armature 66 gains forward acceleration, driving the load 7 to accelerate.

[0091] During launch, the drive coil 625 will be subjected to a large radially outward electromagnetic force. To constrain the drive coil 625 and prevent radial deformation, a stiffening frame with high rigidity and strength is required to fix it to the outside of the drive coil 625. To reduce induced eddy currents, the stiffening frame adopts a hollow frame structure, divided into two semi-circular first fastening steel ribs 622 and second fastening steel ribs 624, and the first fastening steel ribs 622 and second fastening steel ribs 624 are fastened together by bolt assembly 626.

[0092] The reinforcing frame includes: a front insulating retaining ring 621, a rear insulating retaining ring 623, a second fastening steel frame 624, and a bolt assembly 626; the first fastening steel frame 622 and the second fastening steel frame 624 are fastened together by the bolt assembly 626 and assembled into a ring-shaped steel frame; the front insulating retaining ring 621 and the rear insulating retaining ring 623 are respectively fixedly installed at both ends of the ring-shaped steel frame. Further, the front connecting flange and the front insulating retaining ring 621 are connected to the ring-shaped steel frame by a first bolt, and the rear connecting flange and the rear insulating retaining ring 623 are connected to the ring-shaped steel frame by a second bolt.

[0093] Specifically, the front insulating retaining ring 621 and the rear insulating retaining ring 623 are used to position the two ends of the acceleration section 62. Furthermore, the front insulating retaining ring 621 and the rear insulating retaining ring 623 are made of insulating material to prevent the induced eddy currents generated on the reinforcing frame from being conducted to other metal structures on the electromagnetic launch device.

[0094] Specifically, an insulating pad 628 is provided between the first fastening steel frame 622 and the second fastening steel frame 624 to prevent electric creep.

[0095] Furthermore, the bolt assembly 626 includes: a bolt, a nut, a first insulating sleeve, and a second insulating sleeve; the bolt passes sequentially through the first fastening steel member 622, the second fastening steel member 624, and the insulating washer 628 to be fastened to the nut; the bolt head is covered by the first insulating sleeve; the nut is covered by the second insulating sleeve. By providing the insulating sleeve, the electrical conduction between the first fastening steel member 622 and the second fastening steel member 624 can be blocked, effectively reducing eddy current losses.

[0096] Specifically, the positioning cylinder 64 is located at the tail of the acceleration section 62, and its function is to limit the initial position of the load loading. The positioning cylinder 64 is made of non-metallic material, and the positioning cylinder 64 is threadedly connected to the rear insulating retaining ring 623, and is reinforced with thread-locking adhesive during assembly to ensure accurate initial axial positioning. Specifically, the positioning cylinder 64 is arranged side by side with the transmitting armature 66, and the positioning cylinder 64 is fixedly connected to the reinforcing frame.

[0097] Specifically, the positioning sensor 65 is mainly used to detect whether the payload is properly loaded, ensuring launch safety. For example... Figure 12 As shown, the load 7, positioning cylinder 64, and transmitting armature 66 are arranged side by side inside the drive coil 625. A positioning sensor 65 is installed at the end of the positioning cylinder 64 that contacts the transmitting armature 66; the positioning sensor 65 is used to monitor whether the load 7 is properly loaded. When the load 7 is properly loaded, the load 7 contacts one end of the transmitting armature 66, and the positioning sensor 65 contacts the other end of the transmitting armature 66.

[0098] like Figure 14As shown, the transmitting armature 66 includes: an armature outer cylinder 661, an armature bushing 662, and an armature retaining ring 663; the armature bushing 662 and the armature retaining ring 663 are arranged side by side inside the armature outer cylinder 661. Specifically, the strength of the armature bushing 662 is greater than that of the armature outer cylinder 661, which is used to ensure the strength and rigidity of the transmitting armature 66. The conductivity of the armature outer cylinder 661 is greater than that of the armature bushing 662; this is used to ensure the electromagnetic induction of the transmitting armature 66, enabling it to move rapidly under the electromagnetic force of the drive coil 625.

[0099] Specifically, the armature retaining ring 663 is fixedly connected to the armature outer cylinder 661. An annular boss is provided on the inner side of the armature outer cylinder 661. The annular boss is used to limit the axial position of the armature bushing 662. The armature retaining ring 663 clamps the armature bushing 662 between the annular boss and the armature retaining ring 663.

[0100] Rear-seat section 63:

[0101] In one specific embodiment of the present invention, the electromagnetic transmitting device further includes a recoil section 63. For example... Figure 15 As shown, the recoil section 63 is provided with a recoil connecting plate 632 and a rear support 631. Specifically, the acceleration section 62 and the recoil section 63 are connected by a flange; the rear support 631 is a flat plate structure protruding from the main structure of the recoil section 63, and the rear support 631 overlaps the guide rail 57. The rear support 631 is used to support the entire electromagnetic launching device and slides relative to the guide rail 57 as the electromagnetic launching device recoils. The recoil section 63 is made of metal material and has reinforcing ribs arranged circumferentially to increase structural strength.

[0102] Specifically, the recoil connecting plate 632 is used to fix the electromagnetic launching device of the present invention to the anti-recoil device 59. The connection methods between the recoil connecting plate 632 and the anti-recoil device include: bolt connection, welding, bonding, etc.

[0103] In one specific embodiment of the present invention, the detection device 58 uses a camera to aim at the target (fire source). Specifically, the detection device is rotated using a turret to bring the target into the field of view of the zoomable visible light camera. The laser rangefinder performs laser ranging multiple times consecutively, and after removing the maximum and minimum values ​​from the five measurements, the three intermediate values ​​are averaged, and this average value is used as the target slant range, thereby completing the search and measurement of the target.

[0104] Compared with the prior art, the technical solution provided in this embodiment has at least one of the following beneficial effects:

[0105] 1. The transmitting armature 66 of the present invention adopts a split armature, wherein the strength of the armature bushing 662 is greater than that of the armature outer cylinder 661, to ensure the strength and rigidity of the transmitting armature 66. The conductivity of the armature outer cylinder 661 is greater than that of the armature bushing 662; this ensures the electromagnetic induction of the transmitting armature 66, enabling it to move rapidly under the electromagnetic force of the drive coil 625. This ensures both the structural strength of the armature and the electromagnetic induction effect of the armature.

[0106] 2. The present invention provides a front support 611 and a rear support 631 on the outside of the electromagnetic transmitter 6, and the two supports cooperate with the guide rail 57 on the launch turret to realize the recoil sliding during launch, and the recoil force is eliminated by the anti-recoil device 59.

[0107] 3. In the electromagnetic launch system of the present invention, the electromagnetic launcher 6 is mounted on the launch turret, which realizes the adjustment of azimuth rotation and pitch angle to achieve continuous tracking of the target position, thereby ensuring accurate launch of the load 7 and realizing precise operation (fire extinguishing, fire fighting or blasting).
