Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture cage technology, and particularly to an escape structure and method for deep-sea aquaculture cages. Background Technology

[0002] Currently, deep-sea aquaculture cages often employ semi-submersible / fully submersible structures to adapt to harsh sea conditions. However, traditional lifeboat designs present a dilemma: increasing the deck height to ensure personnel evacuation safety significantly increases the main dimensions of the cage, leading to a surge in material usage and costs; conversely, reducing the structural height makes the lifeboat vulnerable to wave impact and failure, and in fully submersible conditions, there is a lack of rapid positioning and safe storage solutions for rescue equipment. Therefore, an integrated design is urgently needed to improve the safety performance of deep-sea aquaculture cages while reducing their main dimensions and costs. Summary of the Invention

[0003] The main objective of this invention is to propose an escape structure and method for deep-sea aquaculture cages, aiming to improve the safety of workers operating in deep-sea aquaculture cages.

[0004] To achieve the above objectives, the present invention proposes an escape structure for deep-sea aquaculture cages, comprising: The working platform is located above the main body of the deep-sea aquaculture cage. The deep-sea aquaculture cage includes a central column and multiple supporting columns. Each of the supporting columns is distributed around the central column. The working platform includes a first deck and a second deck spaced apart along the height direction of the central column. The second deck is located above the first deck. The wing-shaped walkway includes a first column and a connecting passage. The first column extends upward from a supporting column. The two ends of the connecting passage connect the first deck and the top of the first column. Both the connecting passage and the second deck are equipped with life-saving devices.

[0005] In one embodiment, the airfoil bridge includes two airfoil bridges, which are located at opposite ends of the work platform.

[0006] In one embodiment, the lifesaving device includes a crane, a rescue boat, and / or a liftable life valve, wherein the rescue boat and the liftable life valve are spaced apart in the connecting channel, and the crane is used to transfer the rescue boat and the liftable life valve to the sea surface.

[0007] In one embodiment, the second deck is also equipped with a throw-out life valve.

[0008] In one embodiment, the escape structure of the deep-sea aquaculture cage further includes a guide rail, which connects the first guide rail and the second guide rail, and the throwable life-saving valve is deployed to the sea surface along the guide rail.

[0009] In one embodiment, the wing-shaped walkway further includes reinforcing columns, with the two ends of the reinforcing columns axially connected to the side wall of the first column and the bottom of the connecting channel, respectively.

[0010] This invention also proposes a method for escaping from deep-sea aquaculture cages, used in the aforementioned deep-sea aquaculture cage escape structure, comprising the following steps: A hoistable life-saving valve and a rescue boat are installed in the connecting passage of the wing-shaped corridor; In the event of operational risks, the crane will be used to lift the hoistable life-saving valve and the rescue boat to the sea surface to help the workers escape.

[0011] In one embodiment, the deep-sea aquaculture cage operates in a semi-submersible state and a fully submersible state. When the deep-sea cage is in a semi-submerged state and there is an operational risk, the crane will be used to lift the liftable life-saving valve and the rescue boat to the sea surface to help the workers escape. When the deep-sea cage is fully submerged, the crane will transfer the hoistable life-saving valve and the rescue boat from the connecting channel to the second deck for fixation. In case of operational risks, the crane will lift the hoistable life-saving valve and the rescue boat to the sea surface to help the workers escape.

[0012] In one embodiment, the step of transferring the life-saving valve and the rescue boat from the first deck to the second deck includes: the step of transferring the sling-on life-saving valve to the second deck includes: The hoistable life-saving valve is pushed to the first deck using a trolley. The hoistable life-saving valve was lifted to the second deck using a crane. The steps for transferring the rescue boat to the second deck include: The rescue boat was lowered to the sea surface; Move the rescue boat to the lifting range of the crane; The rescue boat is transferred to the second deck using the crane. In one embodiment, if the crane malfunctions, a drop-out rescue boat on the second deck is transferred instead. The life valve was thrown directly onto the sea surface to help the workers escape.

[0013] This invention proposes an escape structure for deep-sea aquaculture cages, applicable to deep-sea aquaculture scenarios. The deep-sea environment is characterized by high waves and water pressure, necessitating emergency evacuation for personnel working in aquaculture cages. This structure provides a safe passage and equipment protection for personnel escape. It comprises two main modules: a work platform and a wing-shaped corridor. The work platform, located above the main body of the deep-sea aquaculture cage, serves as the area for daily operations and emergency assembly. The central pillar of the cage body is a supporting structure made of high-strength alloy material, capable of withstanding the loads of the complex deep-sea environment. Multiple supporting pillars are evenly distributed circumferentially along the central pillar, further enhancing the overall structural stability and forming the supporting framework of the cage together with the central pillar. A first deck and a second deck are spaced apart along the height of the central pillar, with the second deck located above the first deck. This double-deck design provides multiple operational spaces for escape; the first deck can serve as an initial assembly and equipment transfer area, while the second deck can serve as a high-level emergency standby and backup equipment storage area.

[0014] The wing-shaped corridor is crucial for connecting the escape route to the supporting structure. The first column extends upwards from a supporting column, utilizing the same high-strength material to ensure a strong connection. The connecting corridor connects the first deck to the top of the first column at both ends. Its wing-shaped design reduces the impact of sea winds on the corridor, ensuring safe passage for personnel. Both the connecting corridor and the second deck are equipped with life-saving devices to provide equipment support for personnel escape in the event of operational risks.

[0015] The central pillar and supporting pillars form a stable support system to bear the weight of the work platform. The first and second decks are arranged in a layered layout based on the central pillar to meet the needs of different escape stages. The first pillar of the wing-shaped corridor is fixed by the extension of the supporting pillars, and the connecting passage connects the first deck to the external support structure, forming an escape route. The work platform provides the operational foundation, the wing-shaped corridor provides the escape route, and the rescue device provides evacuation tools. The three work together to ensure that personnel can evacuate quickly and safely in an emergency, effectively improving the safety of deep-sea aquaculture operations. Attached Figure Description

[0023] Currently, deep-sea aquaculture cages often employ semi-submersible / fully submersible structures to adapt to harsh sea conditions. However, traditional lifeboat designs present a dilemma: increasing the deck height to ensure personnel evacuation safety significantly increases the main dimensions of the cage, leading to a surge in material usage and costs; conversely, reducing the structural height makes the lifeboat vulnerable to wave impact and failure, and in fully submersible conditions, there is a lack of rapid positioning and safe storage solutions for rescue equipment. Therefore, an integrated design is urgently needed to improve the safety performance of deep-sea aquaculture cages while reducing their main dimensions and costs.

[0024] To solve the above problems, please refer to... Figures 1 to 3 This invention proposes an escape structure 100 for a deep-sea aquaculture cage, including a working platform 1 and a wing-shaped corridor 2. The working platform 1 is located above the main body 20 of the deep-sea aquaculture cage. The deep-sea aquaculture cage includes a central column 201 and multiple supporting columns 202, with each supporting column 202 distributed around the central column 201. The working platform 1 includes a first deck 11 and a second deck 12 spaced apart along the height direction of the central column 201, with the second deck 12 located above the first deck 11. The wing-shaped corridor 2 includes a first column 21 and a connecting channel 22. The first column 21 extends upward from a supporting column 202, and the two ends of the connecting channel 22 connect the first deck 11 and the top of the first column 21. Both the connecting channel 22 and the second deck 12 are equipped with life-saving devices 3.

[0025] The present invention proposes an escape structure 100 for deep-sea aquaculture cages, applicable to deep-sea aquaculture scenarios. The deep-sea environment is characterized by high waves and water pressure, posing an emergency evacuation need for personnel working in aquaculture cages. This structure provides a safe passage and equipment protection for personnel escape. It comprises two main modules: a work platform 1 and a wing-shaped corridor 2. The work platform 1 is located above the main body 20 of the deep-sea aquaculture cage and serves as the area for daily operations and emergency assembly. The central column 201 of the cage body 20 is a supporting structure made of high-strength alloy material, capable of withstanding the loads of the complex deep-sea environment. Multiple supporting columns 202 are evenly distributed circumferentially along the central column 201, further enhancing the overall structural stability and forming the supporting skeleton of the cage together with the central column 201. The central column 201 is provided with a first deck 11 and a second deck 12 at intervals along the height direction. The second deck 12 is located above the first deck 11. This double-deck design provides multiple operating spaces for escape. The first deck 11 can be used as an initial assembly and equipment transfer area, while the second deck 12 can be used as a high-level emergency standby and backup equipment storage area.

[0026] The wing-shaped corridor 2 is crucial for connecting the escape route to the supporting structure. The first column 21 extends upwards from a supporting column 202, utilizing the same high-strength material to ensure a strong connection. The connecting corridor 22 connects the first deck 11 to the top of the first column 21 at both ends. Its wing-shaped design reduces the impact of sea winds on the corridor, ensuring safe passage for personnel. Both the connecting corridor 22 and the second deck 12 are equipped with life-saving devices 3, providing equipment support for personnel escape in the event of operational risks.

[0027] The central column 201 and supporting columns 202 form a stable support system to bear the weight of the work platform 1. The first and second decks 12 are arranged in a layered layout based on the central column 201 to meet the needs of different escape stages. The first column 21 of the wing-shaped corridor 2 is fixed by the extension of the supporting column 202, and the connecting passage 22 connects the first deck 11 to the external support structure to form an escape passage. The work platform 1 provides the operating foundation, the wing-shaped corridor 2 provides the escape route, and the rescue device 3 provides the evacuation tools. The three work together to ensure that personnel can evacuate quickly and safely in an emergency, effectively improving the safety of deep-sea aquaculture operations.

[0028] In an alternative embodiment, please refer to Figures 1 to 3The wing-shaped walkways 2 consist of two sections, located at opposite ends of the working platform 1. Firstly, the two symmetrically positioned wing-shaped walkways 2 ensure more balanced stress distribution on the working platform 1, preventing structural center of gravity shift caused by a single-sided walkway and reducing swaying of the cages in wind and waves due to uneven stress, thus ensuring the overall structural reliability in emergencies. Secondly, the symmetrically distributed walkways provide workers with a two-way escape route. When one passageway becomes unusable due to wind, waves, equipment malfunction, or other reasons, personnel can quickly switch to the other passageway, significantly reducing the risks associated with a single escape route.

[0029] Each wing-shaped walkway 2 has its first column 21 extending upwards from the corresponding supporting column 202. Connecting channels 22 connect the first deck 11 to the tops of the first columns 21 on both sides, forming a double-channel structure. The wing-shaped design of the connecting channels 22, with its symmetrical layout on both sides, also reduces the overall resistance of the cage in ocean currents, improving the structure's resistance to wind and waves. Independent life-saving devices 3 are installed on both the connecting channels 22 and the second deck 12 of the two walkways, providing double insurance for escape equipment and further ensuring the availability of equipment in emergencies. The two symmetrically arranged wing-shaped walkways 2, through balanced force distribution, bidirectional channels, and dual equipment backup, significantly improve the reliability and efficiency of the escape structure, adapting to the emergency needs of complex deep-sea environments.

[0030] In an alternative embodiment, please refer to Figure 1 , Figure 4 as well as Figure 6 The rescue device 3 includes a crane 31, a rescue boat 32, and / or a hoistable rescue valve 33. The rescue boat 32 and the hoistable rescue valve 33 are spaced apart in the connecting channel 22. The crane 31 is used to transfer the rescue boat 32 and the hoistable rescue valve 33 to the sea surface. The rescue device 3 is a functional component of the escape structure and is directly related to the success rate of personnel evacuation. In actual design, the connecting channel 22 can be equipped with only the rescue boat 32 or the hoistable rescue valve 33, or both. The specific choice can be made according to the number of personnel working on the work platform 1 and the usage requirements. The crane 31 can adopt a hydraulically driven structure and be installed at a preset position connecting the passageway 22 and the deck. Its boom can cover the key areas of the connecting passageway 22 and the deck, ensuring that it can quickly grab the rescue boat 32 and the liftable life valve 33. The rescue boat 32 can be a small rigid inflatable boat, which is lightweight and has good seaworthiness. It can accommodate multiple people and is equipped with life jackets, communication equipment and other emergency supplies. The liftable life valve 33 is a closed inflatable structure with good waterproof and buoyancy performance. It can float on the sea surface for a long time and provide temporary refuge space for people.

[0031] The rescue boat 32 and the hoistable life-saving valve 33 are spaced apart on the connecting channel 22. This avoids congestion caused by concentrated equipment placement and ensures that personnel in different locations can quickly access escape equipment. In an emergency, the crane 31 can quickly hook the rescue boat 32 or the hoistable life-saving valve 33 through preset lifting points and smoothly transfer them to the sea surface. The connection points between the crane 31 and the rescue boat 32 or the hoistable life-saving valve 33 are equipped with dedicated lifting rings to ensure stability during the lifting process. The coordinated operation of the crane 31, rescue boat 32, and hoistable life-saving valve 33 ensures that personnel can be quickly transferred from deep-sea aquaculture cages to a safe area on the sea surface in the event of operational risks, improving the timeliness and safety of escape.

[0032] In another alternative embodiment, please refer to Figure 1 and Figure 5 The second deck 12 is also equipped with a throwable life-saving valve 4. The addition of the throwable life-saving valve 4 further enhances the escape equipment system. The second deck 12, being at a higher position, provides excellent deployment height and visibility for the throwable life-saving valve 4, facilitating operators to quickly assess sea conditions and deploy it accurately. The throwable life-saving valve 4 features an integrated packaging design, normally folded and compressed, requiring minimal storage space. Multiple valves can be evenly distributed along the edge of the second deck 12, increasing equipment reserves. Its outer shell is made of impact-resistant material, capable of withstanding the impact force during deployment.

[0033] In the event of an emergency and a malfunction of crane 31 preventing the timely transfer of rescue boat 32 and sling-type life-saving valve 33, the throwable life-saving valve 4 can serve as an emergency backup device. Operators simply need to release the securing device and push it from the edge of the second deck 12 to the sea surface. Upon contact with seawater, the sling-type life-saving valve 33 will automatically inflate and unfold, forming a floating platform for personnel. The advantage of this design is its rapid response; it eliminates the need for mechanical devices such as crane 31, allowing for deployment in a short time. The high position of the second deck 12 also reduces the obstruction of the sling-type life-saving valve 33 by the net structure during deployment, increasing the success rate. The throwable life-saving valve 4 further enhances the reliability of the escape equipment, reducing the risk of escape failure due to a single device malfunction.

[0034] Furthermore, to facilitate the deployment of the throwable life-saving valve 4, the deep-sea aquaculture cage escape structure 100 also includes a guide rail 5. The guide rail 5 connects the first deck 11 and the second deck 12, and the throwable life-saving valve 4 is deployed to the sea surface along the guide rail 5. The guide rail 5 further optimizes the deployment of the throwable life-saving valve 4, solving the problem of deployment position deviation caused by sea wind and waves during manual deployment. The guide rail 5 is made of stainless steel, which has good corrosion resistance, and its cross-section is U-shaped, which can effectively limit the hoistable life-saving valve 33. One end of the guide rail 5 is fixed to the edge of the second deck 12, and the other end extends to the corresponding position on the first deck 11, forming a downward-sloping deployment channel. The channel is designed with a slope to ensure that the hoistable life-saving valve 33 can slide smoothly down the guide rail 5 under its own weight.

[0035] The guide rail 5 has a smooth surface to reduce friction during the descent of the hoistable life-saving valve 33. Buffer devices can be installed at key points to prevent violent collisions between the hoistable life-saving valve 33 and the guide rail 5. This deployment method is unaffected by manual force or directional control, ensuring the hoistable life-saving valve 33 accurately lands in the designated sea area, even in strong winds. The guide rail 5 also protects the hoistable life-saving valve 33 from scraping against other structures within the net cage during deployment, reducing the risk of equipment damage. The combination of the guide rail 5 and the throwable life-saving valve 4 significantly improves the accuracy and safety of deployment, ensuring that emergency equipment functions where it is most needed.

[0036] In an alternative embodiment, please refer to Figure 1 and Figure 3 The airfoil-shaped walkway 2 also includes reinforcing columns 23, with both ends of the reinforcing columns 23 connected axially to the side wall of the first column 21 and the bottom of the connecting channel 22, respectively. The reinforcing columns 23 are a structural strength enhancement design for the airfoil-shaped walkway 2, providing additional support to address potential deformation or vibration issues in the connecting channel 22 under conditions of strong winds and large waves in deep sea. The reinforcing columns 23 are made of high-strength steel, with a square or circular cross-section, possessing high compressive and shear strength. One end is fixed to the middle of the side wall of the first column 21 by bolts or welding, while the other end is diagonally connected to the middle area of ​​the bottom of the connecting channel 22, forming a triangular support structure. This utilizes the stability principle of a triangle to enhance the connection strength between the connecting channel 22 and the first column 21.

[0037] In daily operations, the reinforcing column 23 reduces the deflection deformation of the connecting passage 22 during personnel passage or equipment placement, ensuring the flatness of the passage. During emergency escapes, it resists the impact of strong winds on the passage, preventing twisting or breakage and ensuring safe passage for personnel. Reinforcing plates are installed at the connection points between the reinforcing column 23 and the first column 21, and the connecting passage 22, further dispersing stress and preventing damage due to concentrated stress at the joints. Not only does it ensure safe passage for personnel, but it also stably supports the weight of equipment such as the rescue boat 32 and the hoistable life-saving valve 33, providing reliable structural safety for the escape passage.

[0038] This invention also proposes a method for escaping from a deep-sea aquaculture cage, used in the above-mentioned deep-sea aquaculture cage escape structure 100. The method includes the following steps: The hoistable life-saving valve 33 and the rescue boat 32 are installed in the connecting passage 22 of the wing-shaped corridor bridge 2; In the event of operational risks, the crane 31 will lift the hoistable life-saving valve 33 and the rescue boat 32 to the sea surface to help the workers escape.

[0039] Step one involves the installation of the hoistable life-saving valve 33 and the rescue boat 32. During installation, the fixed positions of the hoistable life-saving valve 33 and the rescue boat 32 are determined based on the dimensions and load-bearing capacity of the connecting channel 22. Specialized fixing brackets are used to secure the hoistable life-saving valve 33 and the rescue boat 32 to prevent displacement when the net cage sways. Simultaneously, the crane 31 needs to be debugged to ensure it can accurately hook the equipment, and its inflation and start-up functions are tested to ensure the hoistable life-saving valve 33 and the rescue boat 32 are readily available.

[0040] Step two concerns the procedures in case of operational risks. When such risks arise, crane 31 is used to lift the hoistable life-saving valve 33 and rescue boat 32 to the sea surface to assist personnel in their escape. When risks such as typhoons or cage damage are detected, personnel quickly assemble on the first deck 11 or connecting passageway 22. The operator then activates crane 31 and, following a pre-set procedure, sequentially lifts the hoistable life-saving valve 33 and rescue boat 32 from connecting passageway 22 and smoothly deploys them to the sea surface. After deployment, personnel are transferred to the equipment on the sea surface via the wing-shaped walkway 2 or deck passageway, completing the evacuation. This ensures that equipment can be quickly deployed in emergencies, reducing escape preparation time. Pre-installation keeps the equipment in a standby state, and the efficient operation of crane 31 guarantees rapid deployment. The combination of these two features achieves an efficient connection from the occurrence of a risk to personnel evacuation, significantly improving escape efficiency.

[0041] In another embodiment, the escape method for deep-sea aquaculture cages further distinguishes between the semi-submerged and fully submerged states of the cages, and designs specific escape operation procedures accordingly. The semi-submerged state of the deep-sea aquaculture cage refers to the main body 20 of the cage being submerged in water, while the working platform 1 and the wing-shaped corridor 2 are above the sea surface. At this time, the connecting channel 22 is relatively close to the sea surface, and rescue equipment can be directly deployed. The fully submerged state refers to the entire cage submerging to a certain depth underwater, with the working platform 1 and the wing-shaped corridor 2 also underwater. The equipment must first be transferred to a higher deck.

[0042] When the cage is in a semi-submerged state and operational risks arise, the connecting channel 22, located above the sea surface at a suitable distance, allows the crane 31 to directly lift the hoistable life-saving valve 33 and rescue boat 32 from the connecting channel 22 to the sea surface. Personnel can then quickly transfer to the equipment on the sea surface via the wing-shaped corridor 2, reducing transfer steps and increasing escape speed. When the cage is fully submerged, the connecting channel 22 is flooded, making direct equipment deployment impossible. Therefore, the crane 31 must be operated beforehand to transfer the hoistable life-saving valve 33 and rescue boat 32 from the connecting channel 22 to the second deck 12 for secure installation. During the transfer, it is essential to ensure the equipment is sealed and waterproof, and its condition should be checked regularly after installation. When operational risks arise in the fully submerged state, the crane 31 is then operated to lift the hoistable life-saving valve 33 and rescue boat 32 from the second deck 12 to the sea surface to assist personnel in escape. This method, by differentiating operational procedures under different working conditions, ensures that the escape equipment functions effectively in various working states of the cage, improving the applicability of the escape method.

[0043] Furthermore, when the deep-sea aquaculture cages are fully submerged, the hoistable life-saving valve 33 and rescue boat 32 are transferred from the first deck 11 to the second deck 12, ensuring the safe and efficient transfer of equipment in the fully submerged state. Specifically, the transfer steps of the hoistable life-saving valve 33 include: pushing the hoistable life-saving valve 33 to the first deck 11 using a trolley with braked casters for easy movement on the deck and stable fixation during hoisting; then hoisting the hoistable life-saving valve 33 to the second deck 12 using a crane 31. The crane 31 hooks the special lifting ring on the top of the hoistable life-saving valve 33, slowly lifts and moves it to the preset position on the second deck 12, and then securely fixes it with a fixing device after lowering it, completing the transfer.

[0044] For the transfer of rescue boat 32: First, rescue boat 32 is lowered to the sea surface. Then, using crane 31, rescue boat 32 is lifted from connecting channel 22 and smoothly placed into the sea. Next, operators move rescue boat 32 within the lifting range of crane 31 via remote control or guidance, ensuring stable floating on the sea surface. Finally, crane 31 transfers rescue boat 32 to the second deck 12. Crane 31 uses a special lifting device to hook onto the lifting points on both sides of rescue boat 32, slowly lifting it to the height of the second deck 12, precisely placing it on the fixed support on the deck and locking it in place. This step-by-step transfer method is designed with adaptable operation for the different weights and structural characteristics of the liftable life-saving valve 33 and rescue boat 32, ensuring that the equipment is not damaged during the transfer and that the transfer can be completed quickly, providing reliable equipment support for emergency escape in full-divest mode.

[0045] In an optional embodiment, when the crane 31 malfunctions, the throwable life-saving valve 4 on the second deck 12 is directly thrown to the sea surface to help personnel escape. Since the crane 31, as a transfer device, cannot operate due to mechanical failure, power outage, or other reasons, conventional life-saving equipment cannot be deployed. In this case, the throwable life-saving valve 4 becomes a crucial escape method. The throwable life-saving valve 4 on the second deck 12 is pre-stored in an easily accessible location and is configured to cooperate with the guide rail 5.

[0046] When crane 31 malfunctions, operators quickly proceed to the second deck 12, unlock the locking mechanism of the throwable life valve 4, place it at the starting end of guide rail 5, and, guided by guide rail 5, slide the throwable life valve 4 to the sea surface. Upon contact with seawater, the throwable life valve 4 automatically inflates and deploys, forming a floating platform. Simultaneously, personnel evacuate to the sea surface via the emergency exit on the second deck 12, board the throwable life valve 4, and leave the danger zone to await rescue. This plan provides a guarantee for escape in extreme situations. Through the coordination of the throwable life valve 4 and guide rail 5, deployment can be completed without relying on power equipment, ensuring a reliable escape route even if crane 31 fails, further enhancing the safety and reliability of the escape method.
