Description

Technical Field

[0001] This invention relates to the field of deep-sea submersible jettisoning and self-rescue technology, and particularly to a dual-redundant combined jettisoning and self-rescue device for deep-sea submersibles. Background Technology

[0002] The deep-sea environment is complex and ever-changing, fraught with uncertainty and danger, but also rich in mineral resources. Deep-sea submersibles, as crucial national instruments for deep-sea exploration and development, possess significant economic and scientific value. However, due to the complex and unpredictable nature of the deep-sea environment, submersible operations face various unsafe and catastrophic emergencies, resulting in substantial losses. For manned deep-sea submersibles, safety requirements are even higher, concerning not only the submersible itself but also the safety of personnel. Therefore, the safe jettisoning and recovery of deep-sea submersibles has become a critical technical challenge.

[0003] To address catastrophic emergencies involving deep-sea submersibles, a redundant dual jettison design is required. A deep-sea submersible jettison self-rescue device has been developed, incorporating both electromagnetic and electric jettison designs. This aims to ensure the submersible can reliably jettison itself and its crew in emergency situations, thus protecting both the submersible and its personnel. In this invention, the electromagnetic and electric jettison designs are cleverly combined, providing the submersible with multiple jettison options. This redundancy design offers dual options in case of failure, effectively increasing the probability of successful self-rescue. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-redundant combined deep-sea submersible jettisoning self-rescue device, which can safely and reliably jettison itself using electromagnetic and electric jettisoning in the event of a malfunction, and successfully surface and be recovered.

[0005] To achieve the above objectives, the technical solution of the present invention is: a dual-redundant combined deep-sea submersible jettisoning self-rescue device, installed at the bottom of the deep-sea submersible, comprising an electric jettisoning structure, an electromagnetic jettisoning structure, an electric jettisoning link, and an electromagnetic jettisoning link. The electric jettisoning link and the electromagnetic jettisoning link are connected by a connecting shaft to form an object jettisoning clamp, and the electric jettisoning link and the electromagnetic jettisoning link can rotate around the connecting shaft. A spring is connected between the upper parts of the electric jettisoning link and the electromagnetic jettisoning link. The electric jettisoning structure is connected to the upper outer side of the electric jettisoning link, and the electromagnetic jettisoning structure is connected to the upper inner side of the electromagnetic jettisoning link to form a dual-redundant jettisoning structure.

[0006] Furthermore, the electric load-release structure employs a linear motor, which is connected to the electric load-release link via an electric linkage.

[0007] Furthermore, when the linear motor receives the control signal for throwing the load, it drives the electric connecting rod to retract. At the same time, under the influence of the thrust of the spring device, the electric throwing link unfolds around the connecting shaft, allowing the thrown object to be released immediately.

[0008] Furthermore, the electromagnetic throwing structure uses a relay. When the relay is energized, the resulting attraction force stabilizes the electromagnetic throwing link, and the linkage with the electric throwing link reliably fixes the thrown object in position.

[0009] Furthermore, when a power outage occurs, the relay will lose its attraction force, and under the influence of the spring device's thrust, the electromagnetic throwing mechanism will separate from the electric throwing mechanism, and the thrown object will be released rapidly.

[0010] Furthermore, the electric jettisoning mechanism and the electromagnetic jettisoning mechanism are respectively connected to the bottom of the deep-sea submersible via fixed connection holes and are mounted on the bottom of the submersible.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] To address catastrophic underwater failures of deep-sea submersibles, this invention employs a dual-redundancy jettisoning scheme, incorporating both electromagnetic and electric jettisoning mechanisms. This ensures normal jettisoning even in the event of a power outage, guaranteeing the submersible's rapid and reliable ascent in critical situations. This dual-redundancy design provides two options in case of failure, effectively increasing the probability of successful self-rescue. Attached Figure Description

[0017] To more clearly describe the features and functions of the present invention, a detailed description is provided below in conjunction with the accompanying drawings.

[0018] This invention provides a dual-redundant combined jettisoning self-rescue device for the aforementioned deep-sea submersible, employing a combination of electromagnetic and electric jettisoning. Even in the event of a power outage due to a submersible malfunction, it can successfully jettison its ballast and surface. The dual-redundant combined jettisoning self-rescue device includes at least the following:

[0019] (1) Deep-sea submersibles rely on power to drive their propulsion systems, sensor systems, communication equipment, control systems, and other critical components during underwater operations. However, the deep-sea environment is extremely harsh, and the enormous pressure and temperature variations of seawater pose challenges to the safety of the submersible system. In the event of a catastrophic failure of the submersible system, such as leakage of the sealed compartment, failure of the sensor thrusters, or failure of the life support system, the submersible will be unable to carry out normal operations and will need to jettison its ballast and surface for self-rescue.

[0020] (2) During the electric jettisoning process, a series of precise operating procedures are executed to ensure the stability and safety of the submersible. First, the electric unit is activated to provide the necessary power. Then, the jettisoning mechanism is activated, and the speed and angle of jettisoning are controlled by the electric drive system to achieve precise release of the submersible's load. The entire process requires precise control based on the marine environment, the submersible's condition, and mission requirements to prevent damage or instability to the submersible during jettisoning.

[0021] (3) Relays play a crucial role in electromagnetic jettisoning technology. A relay is an electrical switching device that controls a small current to switch a high current, thereby enabling signal transmission or equipment operation in a circuit. As a reliable electronic component, relays can operate stably in various environments, ensuring the accuracy of the jettisoning process. During the jettisoning process of a deep-sea submersible, relays can be configured to control the jettisoning mechanism. When a trigger signal is received, the relay activates electromagnetic force, generating sufficient thrust to jettison the submersible's load. The advantages of this electromagnetic jettisoning method lie in its reliability and speed. Furthermore, electromagnetic jettisoning has a very rapid response speed, enabling the jettisoning of the submersible's load in a very short time, thus ensuring that the mission can proceed as planned.

[0022] (4) Even if the deep-sea submersible encounters a sudden malfunction that causes a complete power outage, the electric jettison will be ineffective because it requires electrical propulsion. However, electromagnetic jettison relies on the relay being energized to attract the jettison mechanism. Although the relay will lose power in the event of a power outage, this will still cause the jettison mechanism to disengage, thereby enabling the deep-sea submersible to jettison and ascend.

[0023] This invention is applicable to situations where deep-sea submersibles encounter catastrophic malfunctions during deep-sea operations and are unable to perform normal operations, requiring emergency jettisoning for self-rescue. In such critical moments, this invention enables reliable jettisoning of the submersible, significantly improving its safety. This technology possesses unique innovation and broad application value.

[0024] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a dual-redundant combined deep-sea submersible jettisoning self-rescue device, comprising:

[0025] (1) Dual-redundant ejection device structure: such as Figure 2 As shown in the figure, the structure mainly includes nine key components: a left fixed connection hole 1 and a right fixed connection hole 3 for easy assembly into the bottom of the submersible; a relay 2 providing suction force when energized, firmly gripping the projectile 7 via an electromagnetic projectile link 8 and an electric projectile link 5; the electromagnetic projectile link 8 and the electric projectile link 5 connected by a connecting shaft 6; and a linear motor 4 connected to the electric projectile link 5 via an electric linkage, clamping the projectile 7. The coordinated closure of the electric projectile link 5 and the electromagnetic projectile link 8 ensures stable load during normal submersible operation; and a spring 9 maintains the stable connection and flexibility of the electromagnetic projectile link 8 and the electric projectile link 5. The figure illustrates how these key components interact. First, the left fixed connection hole 1 and the right fixed connection hole 3 are installed at the bottom of the submersible via connectors, providing support for the installation of subsequent devices. The relay 2 creates a suction effect when energized, tightly connecting to the projectile 7 via the electric projectile link 5. The linear motor 4 is then connected to the electric projectile link 5 via an electric linkage, achieving clamping of the projectile 7. The synergistic effect of the electric jettisoning link 5 and the electromagnetic jettisoning link 8 ensures the stability of the submersible's load. Meanwhile, the spring 9 guarantees the reliable connection and flexibility of the electromagnetic jettisoning link 8 and the electric jettisoning link 5.

[0026] (2) Electric jettisoning structure: The operation procedure of electric jettisoning is as follows: Figure 3 As shown, this covers the load release process under normal energized conditions. When the linear motor 4 receives the load release control signal, the electric linkage retracts, and simultaneously, influenced by the thrust of the spring 9, the electric load release link 5 unfolds via the connecting shaft 6, causing the load 7 to be released immediately. This series of steps constitutes the entire process of electric load release operation, ensuring the efficient implementation of the load release operation.

[0027] (3) Electromagnetic launch structure: The operation procedure for electromagnetic launch is as follows: Figure 4 As shown. When the submersible cannot use conventional electric jettisoning due to malfunction or power failure, the electromagnetic jettisoning mechanism will come into play. When relay 2 is energized, the resulting attraction force stabilizes the electromagnetic jettisoning link 8, and its linkage with the electric jettisoning link 5 reliably fixes the jettisoned object 7 in position. However, once a power failure occurs, relay 2 will lose its attraction force, and then, under the thrust of spring 9, the electromagnetic jettisoning link 8 will separate from the electric jettisoning link 5. At this time, the jettisoned object 7 will be rapidly released. This process fully demonstrates the working principle and steps of electromagnetic jettisoning. Figure 4 The response mechanism of the electromagnetic load-release structure under emergency conditions is described intuitively.
