Description

Technical Field

[0001] This invention relates to the field of emergency rescue cabin technology, specifically a deep-sea emergency support cabin based on basalt composite fiber. Background Technology

[0002] As marine resource development and maritime activities expand into the deep sea, higher standards are being set for emergency safety protection of personnel at sea. As the last refuge for personnel in maritime accidents, the stability of the emergency protection cabin during its floating phase on the sea surface is directly related to the survival probability and life safety of the occupants.

[0003] The existing safety cabins mainly rely on their inherent buoyancy layout and hull design to achieve static stability. This design is completely passive, and its stability is only effective in calm water or very light waves. Once encountering severe sea conditions, the cabin will be completely dominated by the waves, producing violent rolling and pitching. The cabin itself does not have any mechanism to actively generate counterforce or torque to counteract these movements. The occupants inside the cabin will be subjected to continuous and violent shaking and impact, which can easily lead to seasickness, injury, and deterioration or even damage to the working environment of the internal equipment.

[0004] To address the above problems, this invention provides a deep-sea emergency support cabin based on basalt composite fiber to solve these issues. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a deep-sea emergency support cabin based on basalt composite fiber, comprising: The support compartment includes a support section in the middle and guide sections on both sides, with a control compartment inside the guide sections; A sealing cover is installed on the upper end face of the protection section; An attitude sensor is installed on the upper surface of the support section to determine the floating state of the support section; The support bladder is configured as two, symmetrically arranged on both sides of the protection section, and near the bottom; The attitude control components are symmetrically arranged on both sides of the support cabin and located in the middle of the support cabin. Multiple generator fans are configured and rotatably mounted on the guide section; The control chamber is equipped with at least a controller, a liquid storage tank, a pump, a power supply, and an oxygen supply device. The liquid storage tank and the pump are connected to the attitude control component and are controlled by the controller. The power supply is electrically connected to the generator fan to provide additional energy.

[0006] Furthermore, preferably, the protection section and the two guide sections together constitute a spindle-shaped protection compartment.

[0007] Further, preferably, the protection segment includes: The support compartment is located inside the support section; An escalator is fixed inside the safety compartment and located below the closed cover; The riser platform is fixed inside the safety compartment and located below the escalator; Two cylindrical compartments are configured and symmetrically fixed on both sides of the interior of the protection compartment; The cabin assembly is rotatably positioned between the two cylindrical cabins.

[0008] Further, preferably, the cabin assembly includes: The cabin has a hatch installed on one side; Two rotating shafts are provided, symmetrically fixed on both sides of the cabin, and the rotating shafts are rotatably connected to the cylindrical cabin; Damping plates are symmetrically fixed to the outer wall of the rotating shaft; A damping chamber is located between the rotating shaft and the cylindrical chamber; The connection port is located on the side of the cabin away from the cabin door and is connected to the oxygen supply equipment via a hose.

[0009] Furthermore, preferably, the damping chamber is filled with viscous oil, the damping plate is located inside the damping chamber, and its edge is slidably connected to the damping chamber in a sealed manner, and the damping plate has multiple micropores.

[0010] Furthermore, preferably, the inner wall of the cabin is integrally formed from basalt composite fiber through a winding process, and multiple safety seats are fixed inside the cabin.

[0011] Further, preferably, the attitude control component includes: The first bladder is configured as two, symmetrically fixed on both sides of the protection section, and the two first bladders are independently controlled by the pump body; The second bladder is configured as four, which are symmetrically fixed on both sides of the guide section, and each is independently controlled by the pump body.

[0012] Furthermore, preferably, when the support cabin rolls, the pump body injects and extracts water into the first bladders on both sides to suppress the rolling of the support cabin. When the support cabin pitches, the pump body injects and extracts water into the second bladders of the two guide sections to suppress the pitch of the support cabin. When the waves are large, the support cabin is extracted into the support bladder to make the entire support cabin submerged in the seawater.

[0013] Compared with existing technologies, this invention provides a deep-sea emergency support cabin based on basalt composite fiber, which has the following beneficial effects: 1. The protection compartment combines active attitude control with passive stabilization design to effectively improve survival safety in harsh sea conditions. The spindle-shaped protection compartment design reduces water flow resistance, enhances static buoyancy stability, and facilitates maintaining balance in waves, thereby enabling passive stabilization control. 2. The safety section is equipped with escalators, raised platforms and cabin components to optimize the entry and exit path and positioning of the crew. The cabin can rotate to adapt to changes in attitude, improve emergency response efficiency, and the cabin components move in the damping chamber through the rotating shaft and damping plate. The viscous oil absorbs the shaking kinetic energy, reduces the transmission of pitch to the cabin, buffers the impact, improves crew comfort and reduces the risk of equipment damage. 3. The inner wall of the cabin is made of basalt composite fiber in one piece, which is lightweight, high-strength, and resistant to seawater corrosion. The internal safety seats fix the occupants and improve the overall survival safety. 4. The attitude control component actively generates a counter-torque by independently filling and defilling the first and second bladders, which quickly suppresses roll and pitch, and achieves dynamic stability adjustment, thereby performing active attitude control. Furthermore, it adjusts the state of the bladders and support bladders in real time based on attitude sensing, increases the draft in harsh sea conditions, and further ensures the overall stability of the hull.

[0015] Reference Figures 1-5 This invention provides a technical solution: a deep-sea emergency support cabin based on basalt composite fiber, comprising: The support compartment includes a support section 1 located in the middle and guide sections 2 located on both sides, wherein a control compartment 21 is provided inside the guide section 2; The sealing cover 3 is installed on the upper end face of the protection section 1; An attitude sensor 4 is installed on the upper end face of the protection section 1 to determine the floating state of the protection section 1. The support bladder 5 is configured as two, symmetrically arranged on both sides of the protection section 1, and near the bottom; The attitude control components are symmetrically arranged on both sides of the support cabin and located in the middle of the support cabin. Multiple generator fans 8 are configured to rotate on the guide section 2; The control chamber 21 is equipped with at least a controller, a liquid storage tank, a pump, a power supply and an oxygen supply device. The liquid storage tank and the pump are connected to the attitude control component and are controlled by the controller. The power supply is electrically connected to the generator fan 8 to provide additional energy.

[0016] In addition, the protection section 1 and the two guide sections 2 together form a spindle-shaped protection compartment.

[0017] In other words, the support compartment adopts a spindle-shaped streamline design consisting of a central support section 1 and two side guide sections 2. This configuration can effectively reduce drag, improve inherent stability in still water and at low speeds, and provide a good foundation for subsequent active control.

[0018] In this embodiment, the protection segment 1 includes: The protection compartment 11 is located inside the protection section 1; The escalator 12 is fixed inside the safety compartment 11 and located below the closed cover 3; The riser platform 13 is fixed inside the safety compartment 11 and located below the escalator 12; Two cylindrical compartments 15 are configured and symmetrically fixed on both sides of the interior of the protection compartment 11; The cabin assembly 14 is rotatably disposed between the two cylindrical cabins 15.

[0019] The protection section 1 is equipped with an escalator 12, a raised platform 13, and a rotatable cabin component 14. This layout optimizes the internal space and passenger movement. The cabin component 14 can rotate relative to the protection cabin, which can isolate the swaying of the protection cabin and improve the stability of the passenger stay.

[0020] In a preferred embodiment, the cabin assembly 14 includes: The hull 141 has a hatch 142 installed on one side; Two rotating shafts 143 are provided and symmetrically fixed on both sides of the cabin 141, and the rotating shafts 143 are rotatably connected to the cylindrical compartment 15. Damping plates 144 are symmetrically fixed to the outer wall of the rotating shaft 143; A damping chamber 145 is disposed between the rotating shaft 143 and the cylindrical chamber 15; Connection port 146 is located on the side of the cabin 141 away from the cabin door 142, and is connected to the oxygen supply equipment via a hose.

[0021] In addition, the damping chamber 145 is filled with viscous oil, the damping plate 144 is located inside the damping chamber 145, and its edge is slidably connected to the damping chamber 145. The damping plate 144 has multiple micropores.

[0022] It should be noted that the cabin 141 is connected by a rotating shaft 143, and a damping plate 144 is fixed on the rotating shaft 141 and placed in a damping chamber 145 filled with viscous oil. This structure converts the relative rotational motion between the cabin 141 and the support cabin into the flow of oil through the micropores of the damping plate 144, thereby consuming energy and playing a role in passive vibration reduction and shock buffering. The passive energy dissipation mechanism can continuously and smoothly attenuate the swaying energy, improve the comfort of the crew and protect the internal equipment, and further reduce the impact of the support cabin pitch.

[0023] Preferably, the inner wall of the cabin 141 is integrally formed by basalt composite fiber through a winding process, and multiple safety seats are fixed inside the cabin 141.

[0024] In this embodiment, the attitude control component includes: Two first bladders 6 are configured and symmetrically fixed on both sides of the protection section 1, and the two first bladders 6 are independently controlled by the pump body. The second bladder 7 is configured as four, which are symmetrically fixed on both sides of the guide section 2, and each is independently controlled by the pump body.

[0025] In other words, by independently controlling the liquid-filled bladders symmetrically arranged on both sides of the cabin 141 (first bladder 6) and the bow and stern guide sections 2 (second bladder 7), it is possible to actively generate the opposite torque to counteract the roll and pitch, thereby actively suppressing the sway. Combined with the passive suppression of the support cabin, the sway is greatly reduced.

[0026] When the support cabin rolls, the pump injects and extracts water into the first bladders 6 on both sides to suppress the rolling. When the support cabin pitches, the pump injects and extracts water into the second bladders 7 of the two guide sections 2 to suppress the pitch. When the waves are large, the support cabin is extracted into the support bladder 5 to allow the entire support cabin to sink into the seawater.

[0027] In practice, once the support cabin floats in the water, the system is immediately powered on and started. The attitude sensor 4 (usually including an inertial measurement unit IMU) installed on the top begins to monitor the motion status of the support cabin in real time and at high frequency, including key data such as roll angle, pitch angle, angular velocity, and acceleration. This data is transmitted in real time to the controller in the control cabin 21. When a roll occurs ( Figure 4 As the support cabin begins to tilt to the right (starboard side sinking), the controller commands the pump to rapidly inject liquid into the first bladder 6 on the right side, while simultaneously extracting liquid from the first bladder 6 on the left side. The resistance on the left side decreases, while the resistance on the right side increases, generating a righting torque to the left, directly resisting the rolling tendency to the right and pushing the support cabin back to the equilibrium position. When pitching occurs ( Figure 5 When the support cabin tilts (sinks to the right), the controller commands the pump to inject liquid into the second bladder 7 of the right guide section 2, while simultaneously draining liquid from the second bladder 7 of the left guide section 2. The resistance on the right side increases, generating a torque that lifts the left side and suppresses pitching. When encountering high waves, the support cabin faces severe and irregular rolling and pitching, posing a risk of capsizing. The aforementioned rolling and pitching control strategies work together to perform faster and larger-scale fluid volume adjustments to generate a stronger stabilizing torque. At the same time, the draft is increased. The controller commands the pumps to expel air or liquid from the support bladders located on both sides of the bottom of the support cabin, causing the entire support cabin to sink. The volume and cross-sectional area of ​​the part below the waterline are significantly increased, resulting in a greater hydrostatic restoring torque, stronger resistance to tilting, and deeper immersion in the water. The direct impact of surface breaking waves is reduced, and the movement is more stable.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
