Description

Technical Field

[0001] The present invention relates to the technical field of carrier containers, and particularly to a cross-carrier container for object transportation and a launching method. Background Art

[0002] With the rapid development of submarine-launched weapon systems and underwater detection equipment, the stealth, reliability, and penetration ability of underwater launching devices have become the core research topics in the field of national defense technology. The current mainstream technical solutions are mainly divided into two categories: active attitude adjustment type and passive buoyancy release type. For example, the "Water-air Multirotor UAV Cross-medium Control System" disclosed in Chinese Patent CN202211083655.0 represents the active control technology direction. It integrates waterproof rotors, multi-modal sensors, and a humanoid intelligent controller on the UAV body to achieve autonomous attitude adjustment at the gas-liquid interface. Specifically, before the UAV emerges from the water, it needs to continuously calculate the horizontal position in real time through inertial navigation and pressure sensors, and drive the rotors to adjust the pitch angle, roll angle, and heading angle to preset thresholds, and then perform a progressive water-breaking action with an optimal control strategy. However, due to the complexity of the fluid-structure interaction effect at the gas-liquid interface, the attitude adjustment process requires multiple iterative calculations and actuator responses. When the UAV in this patent flies out of the water, it needs to adjust the wing state, flight speed, and heading, which takes a long time and significantly increases the probability of target exposure.

[0003] Another typical technical path is the "Large-depth Underwater Unpowered Aircraft Launching System and Method" disclosed in Chinese Patent CN201710193640.2. This technology makes the launch tube have neutral buoyancy characteristics through precise weight design, uses a preset ballistics model to achieve self-stabilizing floating of the tube body, and finally completes the water surface projection of the aircraft through the ignition of the ejector. Although it omits a complex underwater power system, due to the hydrodynamic characteristics of the cylindrical structure of the tube body, after the top of the launch tube in this patent breaks through the water surface, to prevent water from entering the inner cavity of the launch tube, the top of the launch tube needs to be exposed above the water surface for a long distance to achieve the separation of the front cover. Otherwise, when the ejector works in this patent, the launch tube will have an obvious recoil phenomenon (or cause the tube body to sink and oscillate), resulting in water entering the launch tube, thus affecting the normal ejection of the aircraft and directly affecting the ignition success rate of the aircraft.

[0004] The common problems of the existing technologies are as follows: there are significant technical bottlenecks in terms of stealth and launch reliability during the water surface penetration stage, and it is difficult to achieve a balance between rapid penetration and stealth for both; in addition, traditional launching devices lack an adaptive suppression mechanism for recoil effects and are prone to chain failures caused by the secondary entry of the tube body into the water in high-speed launch scenarios, and this problem is particularly prominent in the deep-sea high-pressure environment. Both of these methods are likely to expose the position.

[0005] Therefore, in view of this, the inventor proposes a cross-carrying container and a launching method for object transportation to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a cross-carrying container for object transportation, so as to solve the dual technical bottlenecks of the high risk of exposure caused by the excessive height of the existing underwater carrier above the water surface and the water ingress at the muzzle of the launching tube caused by the ejection recoil effect, and achieve the dynamic balance between stealth penetration and reliable launching; the second purpose is to propose a launching method for the cross-carrying container.

[0007] In order to achieve the above purposes, the technical solutions adopted by the present invention are as follows: A cross-carrying container for object transportation, including a top cover, a launching tube and a base, the top cover is detachably installed on the top of the launching tube, and the base is installed at the bottom of the launching tube; The base includes an electromagnetic cabin, a plurality of rotating shafts and a plurality of fins, and each fin is installed on the outer periphery of the electromagnetic cabin through a corresponding rotating shaft; and each fin unfolds downward along the axis of the launching tube; A connecting piece is arranged between the electromagnetic cabin and the fin, and the connecting piece has a closed state of driving the corresponding fin to fold up on the outer wall of the electromagnetic cabin and an unfolded state of unfolding outward with the rotating shaft as the rotation center; It further includes a locking structure. When the fin is converted from the closed state to the unfolded state at a preset angle, the fin is mechanically locked with the electromagnetic cabin through the locking structure.

[0008] According to the above technical solution, when the carrying container is in underwater transportation, the electromagnetic cabin controls the fins to fold up. At this time, the electromagnet loses power to adsorb the unlocking iron plate, so that the fins are close to the launching tube to form a streamlined profile; when approaching the water surface for launching, the electromagnet is energized to release the unlocking iron plate, and the elastic element pushes the fins to unfold outward around the rotating shaft. When the fins are unfolded to the preset angle, the clamping post is embedded into the diameter hole of the fin rod connecting part to achieve mechanical locking. The unfolded fins disperse the water flow resistance through a specific inclined surface and form a stable supporting surface, which not only reduces the water splash disturbance when leaving the water but also suppresses the ejection recoil effect by increasing the bottom contact area, enabling the top cover to only partially emerge from the water to safely bounce open and complete the launching, achieving the dynamic balance between stealth penetration and launching stability.

[0009] Further, the fin includes a fin plate and a fin rod, the fin plate and the fin rod are detachably connected, and when the fin plate is in the closed state, the concave surface of the fin plate is attached to the outer wall of the electromagnetic cabin; A connecting part is formed at the bottom of the fin rod, and a pin hole is opened on the connecting part, and the rotating shaft passes through the pin hole to connect the connecting part with the electromagnetic cabin.

[0010] According to the above technical solution, the fin plate and the fin rod are detachably connected by means of bolts, which is convenient for installation and assembly.

[0011] Furthermore, the connecting member includes an electromagnet, an unlocking iron plate and a first elastic member; The electromagnet is a power-off type electromagnet; The electromagnet is fixedly arranged on the electromagnetic cabin, and the unlocking iron plate is installed on one side of the fin plate close to the electromagnetic cabin; Wherein, the unlocking iron plate is arranged corresponding to the electromagnet.

[0012] Furthermore, the connecting member includes an electromagnet, an unlocking iron plate and a first elastic member; The electromagnet is fixedly arranged on one side of the fin plate close to the electromagnetic cabin, and the unlocking iron plate is fixedly installed on the electromagnetic cabin; Wherein, the unlocking iron plate is arranged corresponding to the electromagnet.

[0013] Furthermore, a clamping groove is formed at the bottom of the electromagnetic cabin, the connecting portion is installed in the clamping groove through the rotating shaft, and a smooth transition surface is formed on the connecting portion.

[0014] Furthermore, the locking structure includes a clamping post, a pin, a diameter hole, a circular hole and a straight slot formed in the electromagnetic cabin. The circular hole and the straight slot communicate with each other. A second elastic member is arranged in the circular hole. The clamping post is slidably arranged in the circular hole. The second elastic member has a tendency to drive the clamping post to extend out of the circular hole; When the fin is in the unfolded state, the second elastic member drives the clamping post to extend into the diameter hole to limit the fin.

[0015] According to the above technical solution, when underwater navigation, the electromagnet adsorbs the fin so that the connecting portion closely fits the clamping groove of the electromagnetic cabin. The clamping post cannot be pressed down due to the obstruction of the connecting portion. At this time, the fin is completely retracted and flush with the outer wall of the launching tube to form a streamline shape; when approaching the water surface, after the electromagnet is powered on, the first elastic member pushes the fin to rotate and unfold around the rotating shaft. During the rotation of the connecting portion, the diameter hole gradually aligns with the axis of the clamping post. When the fin is unfolded to 90°, the second elastic member pushes the clamping post to slide down along the circular hole of the electromagnetic cabin and accurately insert into the vertically intersecting diameter hole to complete mechanical locking. At this time, the unfolded fins disperse the water flow impact and form an umbrella-shaped supporting surface, which can not only reduce the height required for emerging (only the local top cover needs to emerge to bounce open) to reduce the exposure risk, but also effectively suppress the sinking of the cylinder body caused by the recoil after launching by increasing the water resistance contact area.

[0016] Furthermore, the pin is located in the straight slot, and the pin can slide in the straight slot. One end of the pin is connected to the clamping post.

[0017] Based on the above technical problems, the pin slidingly connected in the straight slot provides an emergency unlocking channel. Pulling the pin upwards can forcibly retract the card column to achieve fin reset. This double locking mechanism not only ensures the absolute rigidity of the deployed state but also is compatible with the rapid recovery requirements, ultimately achieving the unity of concealed penetration and launch stability.

[0018] Furthermore, the diameter hole is opened on the connecting portion, and the axis of the diameter hole is perpendicular to the axis of the pin hole.

[0019] Furthermore, the diameter of the electromagnetic cabin is smaller than the diameter of the launching tube, and when the fins are folded into the outer wall of the electromagnetic cabin in a closed state, the outer contour of the base and the outer contour of the launching tube form a continuous cylindrical surface.

[0020] According to the above technical scheme, the carrier container achieves a balance between concealed transportation and rapid deployment through size matching. When the fins are folded, the smaller diameter design of the electromagnetic cabin makes the outer surface of the folded fins flush with the outer wall of the launch tube, forming a continuous cylindrical surface that effectively eliminates turbulent noise and water pressure fluctuations caused by structural mutations; this streamlined integration significantly reduces fluid resistance during underwater navigation, while avoiding the sonar reflection characteristics of traditional cylindrical launch tubes due to external components, and achieving radar / sonar stealth effects during the transportation phase; when deployed, the retracted diameter design of the electromagnetic cabin leaves deployment space for the rotation of the fins, so that multiple groups of symmetrically distributed fins can be quickly and synchronously deployed to the preset working angles. The umbrella-shaped support surface formed after deployment greatly expands the bottom contact area, which can effectively disperse the launch recoil and significantly compress the top cover out of the water. Compared with the long-distance water outlet required by traditional technologies, the exposure time is greatly shortened, and ultimately the coordinated optimization of concealed penetration and launch stability is achieved.

[0021] The wing rod is provided with an inclined surface, and the inclined surface is used to reduce water resistance during movement.

[0022] According to the above technical solution, the inclined surface on the wing rod achieves drag reduction and efficiency improvement through fluid mechanics optimization design. When the carrier container moves underwater, the inclined surface is opened to guide the water flow to smoothly separate along the surface of the wing rod, effectively suppressing the turbulent vortex generated by the traditional right-angle structure; in the closed state, the joint of the inclined surface and the adjacent fins forms a continuous guide surface, so that the water flow forms a laminar boundary layer around the base, reducing the surface friction resistance, and overall realizing the low resistance characteristics required for concealment during the transportation stage.

[0023] On the other hand, the present invention further provides a method for launching a straddle carrier container for object transportation, using the straddle carrier container for object transportation as described above, the launching method comprises the following steps: S1: During underwater transportation, the electromagnet of the electromagnetic cabin is a de-energized electromagnet. In the de-energized state, it generates electromagnetic adsorption force to adsorb the unlocking iron plate of the fin to the outer wall of the electromagnetic cabin, so that the fin remains in a folded state and forms a continuous streamlined profile with the launch tube; S2: When the carrier container approaches the water surface, the electromagnet is energized, the electromagnetic adsorption force disappears, and the first elastic member drives the fin to expand around the rotating axis to a preset angle; S3: During the unfolding process of the fin, when the diameter hole of the wing rod connecting part is aligned with the axis of the clamping column of the electromagnetic cabin, the second elastic member pushes the clamping column to insert into the diameter hole to achieve mechanical locking of the fin; S4: In the deployed and locked state, the umbrella-shaped support surface formed by the fins suppresses the recoil effect of launch, and the top cover is partially out of water to complete the pop-up action.

[0024] Beneficial effects of the present invention: 1. The closed locking mechanism of the iron plate is unlocked by adsorbing the electromagnet at the base, so that the fins form a cylindrical streamlined structure with the outer wall of the launch tube when they are folded, significantly reducing the underwater navigation resistance and sonar detection risks; when the carrier container approaches the water surface, the electromagnet is energized to release the fins, and the first elastic member drives the fins to quickly unfold to a locked state. The unfolded fins form an umbrella-shaped support structure, which can disperse the water flow resistance and reduce the buoyancy speed by increasing the contact area, avoiding the sudden bursting of the water surface due to excessive buoyancy speed and avoiding radar monitoring; it can also evenly transfer the recoil force generated by the launch of the drone to the fins, effectively suppressing the sinking of the launch tube or the immersion of the top of the tube, ensuring that the top cover only needs to be partially out of water to launch the drone or aircraft, and achieving full-link optimization from navigation concealment to launch stability.

[0025] 2. This application adopts the linkage mechanism of "electromagnetic release + elastic drive + vertical latch lock". When the fins are unfolded, the clamping column is precisely inserted into the diameter hole at the bottom of the wing rod under the spring preload, forming a rigid mechanical lock, which can maintain a stable unfolded state even under downward thrust; at the same time, the straight slot pin design provides an emergency unlocking channel, and the pin can be manually pulled to forcibly retract the clamping column when the electromagnetic fails, realizing mechanical-electromagnetic dual redundant control. This design breaks through the delay defect of traditional hydraulic deployment, shortens the response time, and the locking structure meets the high robustness requirements in extreme impact environments.

[0026] 3. The fins of this application have both anti-recoil and buoyancy adjustment functions after being deployed: on the one hand, the umbrella-shaped structure actively suppresses the floating speed through water resistance to prevent the carrier container from bursting out of the water and causing exposure; on the other hand, the fins can act as fixed rudders to maintain the stability of floating. In addition, the modular fins (bolted connections) support rapid disassembly and assembly, and are suitable for military reconnaissance, underwater rescue and other multi-scenario tasks, with strong scalability.

[0027] Through the retraction - deployment locking mechanism that combines electromagnetic control and elastic drive, the present invention realizes the dynamic conversion between the streamlined stealth navigation of the underwater transport container and the deployed anti - recoil structure. After deployment, the umbrella - shaped support structure synchronously realizes buoyancy deceleration and recoil force dispersion, taking into account both stealth penetration and launch stability. The present invention adopts a vertical pin - type locking design of a diameter hole - clamping post, combined with the elastic energy storage characteristics of a variable pitch spring, to ensure that the fin quickly unfolds to the precise mechanical locking position after electromagnetic release. This not only avoids the delay defect of traditional hydraulic deployment but also improves the locking reliability through the redundant design of double elastic components, effectively preventing launch failures caused by water ingress at the muzzle of the launch tube.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the protection scope of the present invention.

[0032] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0033] This embodiment proposes a spanning carrier for object transportation, such as Figures 1 to 7 shown, including a top cover 1, a launch tube 2, and a base 3. The top cover 1 and the launch tube 2 fit together. O-ring grooves are provided at the bottom of the top cover 1 and the top of the launch tube 2 for installing sealing rings to prevent liquid from entering the interior of the launch tube 2. The top cover 1 is installed on the top of the launch tube 2. When the drone or aircraft in the launch tube 2 is launched from the launch tube 2, the top cover 1 can be pushed out from the top of the launch tube 2, and the base 3 is installed at the bottom of the launch tube 2.

[0034] As Figures 3 to 6 shown, the base 3 includes an electromagnetic cabin 6, a plurality of rotating shafts 19, and a plurality of fins. Each fin is hinged to the bottom edge of the electromagnetic cabin 6 through a corresponding rotating shaft 19. As a preferred embodiment, the number of the rotating shafts 19 and the fins in this embodiment is preferably four, and they are evenly distributed on the outer periphery of the electromagnetic cabin 6.

[0035] As Figure 2 shown, each fin unfolds from top to bottom along the axis (vertical direction) of the launch tube 2. In this embodiment, by utilizing the natural hydrodynamic force when the carrier floats, the fins can be autonomously unfolded through the action of water flow resistance, and no driving structure (such as telescopic rods, actuators, hydraulic cylinders, motors, etc.) is required to achieve the unfolding operation of the fins. Compared with the traditional reverse flow field unfolding mode from bottom to top, its advantage lies in converting the water flow impact force into the unfolding driving force rather than resistance. This unfolding path that conforms to the fluid movement law not only saves additional power devices, but also achieves a millisecond-level unfolding response through the hydrodynamic self-enhancement effect, forming a geometrically symmetric deceleration support surface at the moment of emerging from the water, while strengthening the mechanical locking reliability of the unfolding. It not only eliminates the energy loss and structural hysteresis during the reverse unfolding of the traditional scheme, but also achieves the dual goals of rapid braking and structural stability with a physically self-consistent mechanical logic.

[0036] A connecting piece is provided between the electromagnetic cabin 6 and each fin. The connecting piece has a closed state in which the corresponding fin is driven to fold in on the outer wall of the electromagnetic cabin 6 and an unfolded state in which it expands outward with the rotating shaft 19 as the rotation center.

[0037] As Figure 3 shown, the fin includes a fin plate 5 and a fin rod 4, and the fin plate 5 and the fin rod 4 are detachably connected; in this embodiment, the fin plate 5 and the fin rod 4 are fixed together by means of bolt connection, which is convenient for installation and assembly. As Figure 5 and Figure 7 shown, a connecting portion 8 is formed at the bottom of the fin rod 4, and a pin hole 9 is formed in the connecting portion 8. The rotating shaft 19 passes through the pin hole 9 for connecting the connecting portion 8 with the electromagnetic cabin 6.

[0038] When the fin plate 5 is in the closed state, the concave surface of the fin plate 5 fits against the outer wall of the electromagnetic cabin 6; as Figure 2 shown, when the fin plate 5 is in the unfolded state, the concave surface of the fin plate 5 faces upward. It should be emphasized that after the top of the launch tube 2 emerges from the water, the unmanned aerial vehicle needs to be quickly ejected and the height above the water surface needs to be as small as possible to avoid being detected (that is, during the upward floating process, it needs to decelerate extremely quickly, and the deceleration performance requirements for the launch tube 2 are relatively high to facilitate the rapid launch of the unmanned aerial vehicle or aircraft); when the fin plate 5 is in the unfolded state, the design with the concave surface of the fin plate 5 facing upward actively constructs an asymmetric resistance mechanism during the stage when the launch tube 2 emerges from the water by reversely applying the airfoil hydrodynamics characteristics. Compared with the traditional water surface anti-rolling scheme with the concave surface facing downward, its unique advantage lies in using the strong turbulent separation effect generated by the reverse of the concave surface of the fin to achieve rapid deceleration, and at the same time, suppressing the rapid upward floating inertia of the launch tube 2 with the vertical downward pressure induced by the reverse curvature. This design not only greatly shortens the height required for the launch tube 2 to emerge from the water and reduces the exposure risk, but also can effectively disperse the recoil force through the umbrella-shaped support structure formed by the fins at the moment of launch, prevent the launch tube 2 from quickly sinking into the water, reduce the water surface fluctuation, and avoid being monitored, skillfully balancing the contradiction between the rapid braking required for stealth penetration and the launch stability. Its core innovation lies in transforming the traditional airfoil structure used to improve the floating stability into an active deceleration control device, and achieving a breakthrough improvement in tactical performance through the directional regulation of fluid separation and energy dissipation.

[0039] As Figure 1As shown, the base 3 is located at the bottom of the launch tube 2, that is, the fins are located at the end of the launch tube 2. The structural innovation of integrating the fins at the end of the launch tube 2 breaks through the spatial limitation of the traditional arrangement of fins along the middle of the launch tube 2. Through the integrated design of end folding and storage and the fluid shape, while ensuring the formation of an effective deceleration support surface after deployment, the compact layout of the carrier container is maintained to the greatest extent. This end-intensive configuration not only eliminates the radial expansion problem caused by the fin deployment mechanism in the middle of the cylinder body occupying the cylinder space in the traditional solution, but also realizes the optimal matching of fluid resistance and structural strength through bottom flow field directional control, ensuring both the low-resistance concealment characteristics during underwater navigation and the ability to form an efficient water reaction surface relying on the end support points at the moment of surfacing, meeting the dual requirements of the carrier container's floating braking and launch recoil resistance with the minimum structural intervention, and reconstructing the spatial coupling relationship between deceleration and the carrier body.

[0040] As a preferred embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the connecting member includes an electromagnet 7, an unlocking iron plate 11 and a first elastic member 10; the electromagnet 7 is fixedly arranged on the electromagnetic cabin 6, the unlocking iron plate 11 is installed on the side of the fin plate 5 close to the electromagnetic cabin 6, and the unlocking iron plate 11 is arranged corresponding to the electromagnet 7.

[0041] In this embodiment, the first elastic member 10 is a variable pitch spring. The variable pitch spring first passes through a bolt from the inner side of the fin plate 5 and then is fixed with a nut, so that the inner side of the fin plate 5 is closely attached to the variable pitch spring 10. A circular groove is formed on the electromagnetic cabin 6. When the fins are retracted and closed on the outer wall of the electromagnetic cabin 6, the variable pitch spring extends into the circular groove. A controller is arranged in the electromagnetic cabin 6, and the controller is connected to the electromagnet 7 for control, and can control the power-on and power-off of the electromagnet 7.

[0042] In a possible implementation, the electromagnet 7 can also be fixedly arranged on the side of the fin plate 5 close to the electromagnetic chamber 6, and the unlocking iron plate 11 is fixedly installed on the electromagnetic chamber 6, and the unlocking iron plate 11 is arranged corresponding to the electromagnet 7. It should be noted that the electromagnet 7 in this embodiment is a power-off type electromagnet or a power-off holding type electromagnet, that is, it is in a holding adsorption state when powered off and in a disconnected state when powered on. The design of using a power-off type electromagnet or a power-off holding type electromagnet cleverly fits the long-term operation characteristics of underwater equipment. Since the carrier container needs to stay underwater for a long time, the energy consumption during the working process must be controlled to a minimum, otherwise the carrier cannot achieve long-term reliable operation. The core advantage of this embodiment is to replace the active control of continuous power consumption with a passive maintenance mechanism of physical adsorption. During long-term underwater navigation, it can not only avoid the risk of accidental deployment of the fins caused by power interruption, but also greatly reduce the standby energy consumption of the system. This self-locking magnetic holding characteristic not only strengthens the structural stability of the hidden state of the carrier, but also significantly improves the system reliability and environmental adaptability through the design of power dependence removal, achieving a deep unity of functional safety and energy efficiency under complex underwater navigation conditions.

[0043] As Figure 3 shown, a clamping groove 16 is opened at the bottom of the electromagnetic chamber 6, the connecting portion 8 is installed in the clamping groove 16 through a rotating shaft 19, a smooth transition surface is opened on the connecting portion 8, a diameter hole 15 is opened on the connecting portion 8. In this embodiment, it is preferably that the diameter of the diameter hole 15 is 12 mm, and the axis of the diameter hole 15 is perpendicular to the axis of the pin hole 9.

[0044] It further includes a locking structure. When the fin is switched from the closed state to the unfolded state at a preset angle, the fin is mechanically locked with the electromagnetic chamber 6 through the locking structure. In this embodiment, the preset angle is preferably 90 degrees, that is, the fin rotates around the rotating shaft 19 and unfolds to a state perpendicular to the launch tube 2.

[0045] Specifically, the locking structure includes a clamping post 14, a pin 13, a diameter hole 15, a circular hole 17 and a straight slot 18 opened on the electromagnetic chamber 6. The circular hole 17 and the straight slot 18 are communicated with each other. A second elastic member 12 is arranged in the circular hole 17. The second elastic member 12 is preferably a spring. The clamping post 14 is slidably arranged in the circular hole 17. The second elastic member 12 has a tendency to drive the clamping post 14 to extend out of the circular hole 17 (that is, as Figure 3 shown, the second elastic member 12 has a tendency to drive the clamping post 14 to move downward); when the fin is in the unfolded state, the second elastic member 12 drives the clamping post 14 to extend into the diameter hole 15 to limit the fin.

[0046] In this embodiment, when the underwater vehicle is submerged, the electromagnet 7 adsorbs the fin, and the clamping post 14 cannot be pressed down due to the obstruction of the connecting portion 8. At this time, the fin is completely retracted and flush with the outer wall of the launching tube 2 to form a streamlined shape, which can reduce the resistance of the carrier container during underwater navigation and the resistance when floating. When the carrier container rises to a certain height (or close to the water surface) above the water surface, the electromagnet 7 is energized at this time, and the electromagnet 7 loses its magnetic force and no longer adsorbs the unlocking iron plate 11. The first elastic member 10 in the compressed state provides an outward elastic force to the fin plate 5. The first elastic member 10 pushes the fin to rotate and unfold around the rotating shaft 19. During the rotation of the connecting portion 8, when the fin is unfolded to a preset angle, the diameter hole 15 is gradually aligned with the axis of the clamping post 14, and the second elastic member 12 pushes the clamping post 14 to slide down along the circular hole 17 in the electromagnetic chamber 6 and accurately insert into the vertically intersecting diameter hole 15 to complete the mechanical locking. At this time, the four fins are completely unfolded in the water, and the unfolded fins form an umbrella-shaped support structure, which can slow down the floating speed of the carrier container and prevent the carrier container from suddenly floating too high and exposing its position. During the process of the unmanned aerial vehicle or aircraft in the launching tube 2 starting to take off or ignite and launch, a downward thrust will be generated on the carrier container, causing the carrier container to have a recoil effect. Since the four fins are in the unfolded state at this time, a reaction force will be generated due to the thrust, which can weaken the recoil effect to prevent the top end of the launching tube 2 from being immersed in the water. If the top end of the launching tube 2 is immersed in the water, it may cause the unmanned aerial vehicle or aircraft to come into contact with a large amount of water during flight or launch and be unable to fly out of the launching tube 2, ensuring that the unmanned aerial vehicle or aircraft will push open the top cover 1 and fly out of the launching tube 2 smoothly after starting, which not only avoids the carrier container from suddenly floating too high and exposing its position but also can slow down the recoil and prevent the launching tube 2 from sinking.

[0047] As a preferred embodiment, as Figure 6 shown, the pin 13 is located in the straight slot 18, and the pin 13 can slide in the straight slot 18. One end of the pin 13 is connected to the clamping post 14. Specifically, one end of the pin 13 can extend into the clamping post 14 and be fixedly connected to the clamping post 14, and the other end of the pin 13 is exactly located inside the straight slot 18. In this embodiment, the pin 13 slidably connected in the straight slot 18 provides an emergency unlocking channel. Pulling up the pin 13 can forcibly retract the clamping post 14 to reset the fin.

[0048] As a preferred embodiment, the diameter of the electromagnetic cabin 6 is smaller than the diameter of the launch tube 2. When the fins are folded in the outer wall of the electromagnetic cabin 6 and are in a closed state, the outer contour of the base 3 and the outer contour of the launch tube 2 form a continuous cylindrical surface. In this embodiment, the carrier container achieves a balance between concealed transportation and rapid deployment through size matching. When the fins are folded, the smaller diameter design of the electromagnetic cabin 6 makes the outer surface of the folded (closed state) fins flush with the outer wall of the launch tube 2, forming a continuous cylindrical surface that effectively eliminates turbulent noise and water pressure fluctuations caused by structural mutations; this streamlined integration significantly reduces fluid resistance during underwater navigation, while avoiding the sonar reflection characteristics of the traditional cylindrical launch tube 2 due to external components, and achieving radar / sonar stealth effect during the transportation stage. The electromagnetic cabin 6 is designed to be retracted in diameter during deployment to leave deployment space for the fins to rotate, so that multiple groups of symmetrically distributed fins can be quickly and synchronously deployed to the preset working angle. The umbrella-shaped support surface formed after deployment greatly expands the bottom contact area, reduces the buoyancy speed, avoids sudden bursting out of the water due to excessive buoyancy, and avoids being monitored by radar. At the same time, the fins also play the role of fixing the rudder during the buoyancy process, ensuring the stability of the entire structure. It can effectively disperse the launch recoil and significantly compress the height of the top cover 1 out of the water. Compared with the long-distance water outlet required by traditional technologies, the water outlet height is greatly shortened, avoiding the exposure of the top cover 1 and the launch tube 2 due to excessive exposure above the water surface, and finally achieving the coordinated optimization of concealed penetration and launch stability.

[0049] As a preferred embodiment, Figure 4 As shown, the wing rod 4 is provided with an inclined surface 20, which is used to reduce the water resistance during movement. The inclined surface 20 on the wing rod 4 is designed through fluid mechanics optimization to achieve drag reduction and efficiency improvement. When the carrier container moves underwater, the inclined surface 20 is provided to guide the water flow to separate smoothly along the surface of the wing rod 4, effectively suppressing the turbulent vortex generated by the traditional right-angle structure; in the closed state, the inclined surface 20 forms a continuous guide surface with the joint of the adjacent fins, so that the water flow forms a laminar boundary layer around the base 3, reducing the surface friction resistance, and realizing the low resistance characteristics required for concealment during the transportation stage as a whole.

[0050] On the other hand, the present invention also provides a method for launching a straddle carrier container for object transportation, using the straddle carrier container for object transportation as described above, the launching method comprises the following steps: S1: During underwater transportation, the electromagnet 7 of the electromagnetic cabin 6 is a de-energized electromagnet, which generates an electromagnetic adsorption force in the de-energized state to adsorb the unlocking iron plate 11 of the fin to the outer wall of the electromagnetic cabin 6, so that the fin remains in a folded state and forms a continuous streamlined profile with the launch tube 2; S2: When the carrier container approaches the water surface, the electromagnet 7 is energized, and the electromagnetic adsorption force disappears. Under the action of water resistance, the fins unfold around the rotating shaft 19 to a preset angle. Specifically, when the carrier container approaches the water surface, the controller controls the electromagnet 7 to be energized, and the electromagnet 7 releases the adsorption of the fins. The first elastic member 10 drives the fins to unfold around the rotating shaft 19. During the unfolding process, the inclined surface 20 of the fin rod 4 guides the smooth separation of the water flow. After the unfolding action is completed, the fins form a symmetrically distributed support structure, providing a spatial reference for subsequent mechanical locking.

[0051] S3: During the unfolding process of the fins, when the axis of the diameter hole 15 of the connecting portion 8 of the fin rod 4 is aligned with the axis of the clamping post 14 of the electromagnetic cabin 6, the second elastic member 12 pushes the clamping post 14 into the diameter hole 15 to achieve mechanical locking of the fins. During the locking process, the clamping post 14 is in the inserted state. After the locking is completed, the fins and the electromagnetic cabin 6 form a rigid connection to ensure the stability of the support structure under dynamic loads.

[0052] S4: In the unfolded and locked state, the umbrella-shaped support surface formed by the fins suppresses the recoil effect after launch, and enables the top cover 1 to complete the popping action after partially emerging from the water. The unfolded fins form an umbrella-shaped support surface, which actively suppresses the floating speed of the carrier container through fluid resistance, and at the same time disperses the recoil force generated by the launch, reducing the exposure risk.

[0053] In this application, when the carrier container is underwater launched, the electromagnetic cabin 6 controls the fins to fold. At this time, the electromagnet 7 is de-energized to adsorb and unlock the iron plate 11, so that the fins are closely attached to the launch tube 2 to form a streamlined profile. When approaching the water surface for launch, the electromagnet 7 is energized to release the unlocking iron plate 11, and the first elastic member 10 pushes the fins to unfold outward around the rotating shaft 19. When the fins are unfolded to the preset angle, the clamping post 14 is embedded in the diameter hole 15 of the connecting portion 8 of the fin rod 4 to achieve mechanical locking. This can not only prevent the launch tube 2 from suddenly floating too high and causing excessive water splash disturbance when emerging from the water, but also suppress the recoil effect after launch by increasing the bottom contact area, enabling the top cover 1 to only need to partially emerge from the water to safely pop open and complete the launch, achieving the dynamic balance between stealth penetration and launch stability, solving the dual technical bottlenecks of the existing underwater carrier container being prone to exposure risk and the recoil effect after ejection causing water ingress into the launch tube 2 and affecting launch stability, and achieving the dynamic balance between stealth penetration and reliable launch; this application has high application value and high reliable performance.
