Description

Technical Field

[0001] This utility model relates to the field of marine seismic exploration technology, and in particular to a modular rope pod with a seismic node split design. Background Technology

[0002] In the field of marine seismic exploration technology, there are specially designed seabed seismic nodal devices equipped with specialized seismic sensors. The primary function of these sensors is to receive seismic wave signals from the seabed. Through detailed analysis and processing of these signals, scientists can conduct in-depth exploration and research into the structure and properties of the seabed strata. To deploy these seismic nodal devices to the seabed, a manual hook is typically used to connect the seismic nodal to a nodal rope. Subsequently, operators lower the nodal rope, along with the seismic nodal, into the water, enabling precise deployment and retrieval of the seismic nodal device.

[0003] In the actual construction process, operators first need to attach the seismic nodes to the fixed anchor points of the node ropes. Next, they will deploy the node ropes and seismic nodes sequentially into the water according to pre-designed intervals. This process needs to be repeated multiple times to ensure sufficient coverage of the seabed. After the seismic wave acquisition is completed, the operators need to manually remove the node hooks from the fixed anchor points of the node ropes. Subsequently, the cables are retrieved and properly stored for future reuse. The entire process must be carefully executed according to established procedures to ensure the accuracy of data acquisition and the safety of the equipment.

[0004] In the technical applications of seismic node equipment, the deployment and retrieval of seismic node cables are typically accomplished using drum winches, and these cables are stored in the winches. However, the storage capacity of drum winches is limited; they cannot accommodate cables exceeding a certain length. Furthermore, to maintain a fixed spacing between seismic nodes, a node rope anchor needs to be installed at regular intervals along the cable. When the winch performs a retrieval operation, the tension on the cable causes mutual compression between the node rope anchors and the underlying cable, preventing the cable from being successfully deployed and requiring manual intervention. This reduces operational efficiency and increases manpower and time consumption. Moreover, existing node cable deployment and retrieval devices are usually fixedly installed on the deck of a ship, limiting their mobility and making it inconvenient to move them between different work areas.

[0046] The advantages and positive effects of this utility model are:

[0047] (1) The containerized design allows for quick installation and disassembly, offering high adaptability and wide compatibility with various vessels, from large ocean-going cargo ships to flexible near-shore vessels. Even with different vessel types and sizes, the containerized equipment seamlessly integrates into the overall vessel architecture through clever design and installation, meeting the diverse needs of different vessels; it can be disassembled into multiple parts. Its suitable size and weight facilitate transportation. On land, it can be easily loaded and transported by ordinary freight trucks; at sea, it can be placed directly in the cargo hold of the transport vessel, reducing difficulties and costs during transportation. Furthermore, during equipment use, if a malfunction occurs requiring replacement or repair, the disassembled design allows staff to quickly locate the problematic component, disassemble it individually for replacement or repair, eliminating the need for large-scale disassembly of the entire equipment, greatly improving the efficiency of equipment replacement and repair, and reducing maintenance costs.

[0048] (2) The use of cable-stayed bulkheads allows for flexible extension or reduction of module length when the ship needs to carry longer cables, by adding or removing cable-stayed bulkheads to meet different loading requirements. Width adjustment is also convenient, allowing staff to adapt the modules to the actual width of the ship's hold, ensuring that the equipment is installed securely and without wasting space.

[0049] (3) The longitudinal and lateral travel mechanisms, working in tandem, further enhance the efficiency and stability of the operation. During operation, the longitudinal travel mechanism moves smoothly along the longitudinal direction of the ship, and its speed and stroke can be precisely controlled according to the actual needs of cable laying. During cable laying, it drives the cable to extend evenly forward and backward along the ship, ensuring uniformity in the longitudinal distribution. The lateral travel mechanism works in conjunction with the longitudinal travel mechanism, operating perpendicular to the ship's longitudinal direction, ensuring even distribution of the cable on both sides of the ship. The longitudinal and lateral travel mechanisms work together to lay the cable evenly and systematically.

[0050] Meanwhile, the even distribution of cables and the reasonable spacing between each cable significantly reduce the likelihood of them tangling or getting stuck. This avoids the risk of cable wear or breakage caused by uneven tension; in existing cable laying operations, cable jamming is a frequent problem, not only consuming a lot of time to resolve but also potentially damaging the cables and equipment, seriously affecting the progress of the operation. The longitudinal and lateral travel mechanisms improve operational efficiency.

[0051] (4) The cable retrieval and clamping mechanism at the seismic node is a key component ensuring precise and safe cable retrieval and deployment operations. It combines mechanical structure with hydraulic control technology to achieve precise adjustment of the cable retrieval and deployment tension. In actual operation, adjusting tire pressure is an effective way to change the cable retrieval and deployment tension. When a smaller tension is needed to gently retrieve and deploy the cable, especially when dealing with relatively fragile seismic monitoring node cables, operators can reduce the tire pressure connected to the clamping mechanism, thereby reducing the pressure of the clamping mechanism on the cable and thus reducing the cable retrieval and deployment tension. Conversely, if a larger tension is needed for rapid cable retrieval and deployment or to cope with complex sea conditions, increasing the tire pressure increases the friction of the clamping mechanism on the cable, thereby increasing the retrieval and deployment tension.

[0052] Meanwhile, the stroke adjustment of the clamping cylinder changes the cable retrieval and release tension. The clamping cylinder directly acts on the clamping device by precisely controlling the extension and retraction stroke of the piston rod. When the piston rod extends a longer stroke, the clamping force on the cable increases, and the cable retrieval and release tension increases accordingly. This is suitable for ensuring stable cable retrieval and release in harsh environments such as strong winds and undercurrents, preventing the cable from becoming uncontrollable due to external interference. Conversely, when the piston rod retracts, shortening its stroke, the clamping force on the cable decreases, and the cable retrieval and release tension decreases, meeting the need for gentle cable handling in calm sea conditions. This method of changing the cable retrieval and release tension by adjusting tire pressure and the clamping cylinder stroke allows the vessel to flexibly and precisely control the tension according to different operating conditions and cable characteristics during seismic node cable retrieval and release operations, greatly improving the safety and reliability of the operation.

[0064] To better understand this utility model, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0065] Example 1

[0066] like Figures 1-4 As shown, the seismic node modular rope magazine is used for the rapid deployment and retrieval of seismic node cables. The rope magazine includes:

[0067] Container 1, wherein the top of container 1 is a completely open structure;

[0068] Furthermore, the container 1 is provided with multiple cable storage compartments 101. The cable storage compartments 101 are movably installed inside the container 1. The cable storage compartments 101 divide the container 1 into multiple preset cable storage compartments according to the amount of cable stored in the container 1 and the length of the seismic node cable.

[0069] Specifically, when a ship needs to carry long cables, the module length can be flexibly extended or shortened by adding or removing cable storage bulkheads to meet different loading requirements. Width adjustment is equally convenient; staff can adapt the modules according to the actual width of the ship's hold, ensuring that the equipment is installed securely within the ship without wasting space.

[0070] Furthermore, the container 1 includes multiple detachable fixing plates 102 and multiple container corner fittings 103; the bottom corners of every two detachable fixing plates 102 are connected by the container corner fittings 103.

[0071] Specifically, it can be quickly installed and disassembled, boasting extremely high adaptability and wide compatibility with various types of vessels, from large ocean-going freighters to flexible coastal vessels. Even with different vessel types and sizes, the containerized equipment can seamlessly integrate into the vessel's overall architecture through ingenious design and installation methods, meeting the diverse needs of different vessels; it can also be disassembled into multiple parts. Its suitable size and weight facilitate transportation. For land transport, ordinary freight trucks can easily load and transport it; for sea transport, it can be placed directly in the cargo hold of the transport vessel, reducing difficulties and costs during transportation. Furthermore, during equipment use, if a malfunction occurs requiring component replacement or repair, the disassembled design allows personnel to quickly locate the problematic component, disassemble it individually for replacement or repair, eliminating the need for large-scale disassembly of the entire equipment, greatly improving the efficiency of equipment replacement and repair, and reducing maintenance costs.

[0072] Furthermore, the detachable fixing plate 102 is provided with a plurality of viewing doors and windows 104, which are used to observe the deployment of the seismic node cable inside the container 1.

[0073] Specifically, the exterior of the 104 viewing door is made of 316 stainless steel, a material renowned for its excellent corrosion resistance and high strength. In the complex marine operating environment, it effectively resists seawater erosion and possesses excellent impact resistance. Even in the event of a collision, turbulence, or other unexpected situations, the 316 stainless steel frame ensures structural integrity, protecting the internal equipment and personnel. The interior uses transparent PVC panels, whose high transparency provides operators with a clear view, allowing them to observe the deployment and retraction of cables within the equipment at any time.

[0074] The rope storage also includes a connecting mounting frame 2, which is installed at the top of the container 1; the connecting mounting frame 2 is used to support components for the rapid deployment and retraction of seismic node cables;

[0075] The rope storage also includes: a longitudinal traveling mechanism 3, which is mounted on the connecting mounting frame 2 along the longitudinal direction of the container 1;

[0076] Furthermore, the longitudinal traveling mechanism 3 includes:

[0077] At least one set of longitudinal guide rails 301, each set of longitudinal guide rails 301 is mounted on the opposing longitudinal beams of the connecting mounting frame 2; the longitudinal guide rails 301 are provided with longitudinal traveling racks 302 inside the guide rails;

[0078] At least one set of longitudinal mounting bodies 303, each of the longitudinal mounting bodies 303 being fitted onto a corresponding longitudinal guide rail 301;

[0079] At least one set of two-axis longitudinal travel drive gears 304, each of the two-axis longitudinal travel drive gears 304 is mounted on a corresponding longitudinal mounting body 303, and each of the two-axis longitudinal travel drive gears 304 is respectively mounted in the guide rail of the corresponding longitudinal guide rail 301;

[0080] At least one set of longitudinal travel drive motors 305, each of the longitudinal travel drive motors 305 is mounted on a corresponding longitudinal mounting body 303, and the drive shaft of each of the longitudinal travel drive motors 305 is connected to the longitudinal travel drive gears 304 mounted on the corresponding two shafts.

[0081] The two-axis longitudinal travel drive gear 304 meshes with the longitudinal travel rack 302;

[0082] The two-axis longitudinal travel drive gear 304 moves along the length direction of the longitudinal guide rail 301 through synchronous drive of the longitudinal travel drive motor 305.

[0083] The rope compartment also includes: a lateral travel mechanism 4, which is installed on the longitudinal travel mechanism 3 along the lateral direction of the container 1;

[0084] Furthermore, the lateral travel mechanism 4 includes:

[0085] At least one transverse guide rail 401 is mounted on the longitudinal mounting body 303; the transverse guide rail 401 is provided with a transverse traveling rack 402 inside the guide rail;

[0086] A horizontal mounting body 403 is fitted onto a horizontal guide rail 401.

[0087] At least one two-axis lateral travel drive gear 404 is mounted on a lateral mounting body 403 and located within the guide rail of a lateral guide rail 401.

[0088] At least one lateral travel drive motor 405 is mounted on a lateral mounting body 403, and the drive shaft of the lateral travel drive motor 405 is connected to the lateral travel drive gears 404 mounted on the corresponding two shafts.

[0089] The two-axis transverse travel drive gear 404 meshes with the transverse travel rack 402.

[0090] The two-axis transverse travel drive gear 404 moves along the length direction of the transverse guide rail 401 under the drive of the transverse travel drive motor 405.

[0091] Specifically, the coordinated operation of the longitudinal and lateral travel mechanisms further enhances the efficiency and stability of the operation. During operation, the longitudinal travel mechanism moves smoothly along the ship's longitudinal direction, and its speed and stroke can be precisely controlled according to the actual needs of cable laying. During cable laying, it drives the cable to extend evenly forward and backward along the ship, ensuring uniform longitudinal distribution. The lateral travel mechanism works in conjunction with the longitudinal travel mechanism, operating perpendicular to the ship's longitudinal direction, ensuring even distribution of the cable on both sides of the ship. The coordinated operation of the longitudinal and lateral travel mechanisms systematically and evenly lays out the cable.

[0092] Meanwhile, the even distribution of cables and the reasonable spacing between each cable significantly reduce the likelihood of them tangling or getting stuck. This avoids the risk of cable wear or breakage caused by uneven tension. In existing cable laying operations, cable jamming is a frequent problem, not only consuming a lot of time to resolve but also potentially damaging the cables and equipment, severely impacting the work progress. The longitudinal and lateral travel mechanisms improve work efficiency.

[0093] The rope compartment also includes: a seismic node cable retraction and clamping mechanism 5, which is installed on the lateral travel mechanism 4; the seismic node cable retraction and clamping mechanism 5 is used to retract or clamp the seismic node cable.

[0094] The transverse traveling mechanism 4 drives the seismic node cable winding and clamping mechanism 5 to move in the transverse direction of the container 1, and the longitudinal traveling mechanism 3 drives the transverse traveling mechanism 4 and the seismic node cable winding and clamping mechanism 5 to move in the longitudinal direction of the container 1, so as to realize the winding and unwinding of the seismic node cable, and the seismic node cable is evenly distributed in the container 1.

[0095] Furthermore, the earthquake node cable retraction and clamping mechanism 5 includes:

[0096] At least two fixed mounting plates 501 are rotatably mounted on the transverse mounting body 403; the fixed mounting plates 501 are used to support components of the seismic node cable winding and clamping mechanism 5.

[0097] At least two take-up and release wheel drive motors 502, each of the take-up and release wheel drive motors 502 being mounted on a corresponding fixed mounting plate 501;

[0098] At least two take-up and release rollers 503, each take-up and release roller 503 is mounted on the drive shaft of the corresponding take-up and release roller drive motor 502;

[0099] At least one take-up and release roller clamping cylinder 504 is mounted on a transverse mounting body 403, and the telescopic end of the take-up and release roller clamping cylinder 504 is hinged to one of the fixed mounting plates 501.

[0100] When the telescopic end of the take-up and release pair clamping cylinder 504 drives one of the fixed mounting plates 501 to rotate counterclockwise, the take-up and release pair 503 mounted on the fixed mounting plate 501 moves closer to the other take-up and release pair 503, thereby achieving the clamping of the take-up and release pair.

[0101] When the take-up and release wheels are clamped, the two take-up and release wheels 503 complete the retrieval of the seismic node cable by synchronously rotating the take-up and release wheel drive motor 502.

[0102] When the telescopic end of the take-up and release roller clamping cylinder 504 drives one of the fixed mounting plates 501 to rotate clockwise, the take-up and release roller 503 mounted on the fixed mounting plate 501 moves away from the other take-up and release roller 503, thus releasing the take-up and release rollers.

[0103] When the take-up and release line pulleys are released, the end of the seismic node cable is dragged freely, thus releasing the seismic node cable.

[0104] Specifically, the seismic node cable retrieval and clamping mechanism 5 is a key component ensuring the precision and safety of cable retrieval and deployment operations. It combines mechanical structure with hydraulic control technology to achieve precise adjustment of the cable retrieval and deployment tension. In actual operation, adjusting tire pressure is an effective way to change the cable retrieval and deployment tension. When a smaller tension is needed to gently retrieve and deploy the cable, especially when dealing with more vulnerable seismic monitoring node cables, operators can reduce the tire pressure connected to the clamping mechanism, thus reducing the pressure of the clamping mechanism on the cable and consequently reducing the cable retrieval and deployment tension. Conversely, when encountering situations requiring a larger tension for rapid cable retrieval and deployment or dealing with complex sea conditions, increasing the tire pressure increases the friction of the clamping mechanism on the cable, thereby increasing the retrieval and deployment tension.

[0105] Meanwhile, the stroke adjustment of the clamping cylinder changes the cable retrieval and release tension. The clamping cylinder directly acts on the clamping device by precisely controlling the extension and retraction stroke of the piston rod. When the piston rod extends a longer stroke, the clamping force on the cable increases, and the cable retrieval and release tension increases accordingly. This is suitable for ensuring stable cable retrieval and release in harsh environments such as strong winds and undercurrents, preventing the cable from becoming uncontrollable due to external interference. Conversely, when the piston rod retracts, shortening its stroke, the clamping force on the cable decreases, and the cable retrieval and release tension decreases, meeting the need for gentle cable handling in calm sea conditions. This method of changing the cable retrieval and release tension by adjusting tire pressure and the clamping cylinder stroke allows for flexible and precise control of the tension during seismic node cable retrieval and release operations, based on different operating conditions and cable characteristics, greatly improving the safety and reliability of the operation.

[0106] Furthermore, the transverse mounting body 403 is provided with a cable passage hole 6;

[0107] During the rapid deployment and retraction of the seismic node cable, the seismic node cable is guided through the cable passage hole 6.

[0108] Implementation process: (I) Cable collection process

[0109] S1. Cable Insertion and Clamping: When retrieving the node cable, it is essential to ensure that the cable is accurately inserted through the cable guide hole. The cable guide hole is precisely designed, and its size and position ensure that the cable will not jam or shift during insertion. Once the cable is successfully inserted, the cable haul-in / unhaul-out mechanism begins operation, clamping the pulleys. At this point, the two winches gradually approach and contact each other. At the moment of contact, due to the strong pressure, the surface of the winches will slightly deform, thus firmly clamping the node cable and ensuring that the cable will not loosen or slip during subsequent retrieval.

[0110] S2. Recycling Speed ​​Control: Based on the required recycling speed, operators need to precisely control the recycling process using a specialized control system. This system connects to various sensors and actuators, enabling real-time monitoring of the recycling speed and status. Operators can input the corresponding speed parameters on the control system's interface, and the system will automatically adjust the motor speed to achieve precise control of the recycling speed, meeting the needs of different operating scenarios.

[0111] S3. Truss Movement and Cable Retrieval: The two-axis truss plays a crucial role in the entire cable retrieval process. It reciprocates back and forth and side to side above the cable bin according to the winch speed. The amplitude and frequency of this reciprocating motion are rigorously calculated and adjusted to ensure the retrieved cable is evenly wound within the cable bin, avoiding safety hazards and subsequent usage problems caused by uneven cable winding. Simultaneously, the winch of the cable retrieval mechanism begins to rotate, using friction to gradually reel in the cable, ensuring each winding is tight and orderly.

[0112] S4. Automatic Cabin Changing: During the retrieval process, sensors constantly monitor the status of the rope cabins. When a sensor detects that a cabin is about to be full, it immediately transmits a signal to the control system. Upon receiving the signal, the control system quickly initiates the automatic cabin changing procedure. First, the take-up and release mechanism pauses its current take-up action. Then, through a series of precise mechanical structures and the coordinated work of the control system, the cable is smoothly switched to another empty cabin to continue the node rope retrieval operation, ensuring the continuity and efficiency of the retrieval work.

[0113] S5. End of Operation and Reel Adjustment: When the retrieval operation is completed, the final crucial step is to adjust the reel opening and closing according to the operation requirements. Operators need to carefully review the operation requirements document or follow instructions from superiors to understand the specific requirements for reel opening and closing. Then, through the operation control system, slowly adjust the reel opening and closing degree to achieve the specified state, preparing for the next retrieval or release operation.

[0114] (II) Line laying process

[0115] S1. Sheave Opening and Rope Dragging: When a release node is needed, the rope cabin take-up and release mechanism first opens the sheave. The opening process of the sheave needs to be smooth and rapid to ensure that the rope can be released smoothly. Once the sheave is open, the end of the rope will drag freely under the action of external tension. During this process, close attention should be paid to the dragging of the rope to prevent abnormal phenomena such as rope knots or tangles.

[0116] S2. Winch Rotation Speed ​​Control: Based on on-site operational requirements and conditions, operators need to precisely control the winch rotation speed. On-site operational conditions may include various factors such as wind force, terrain, and the stability of the work platform. Operators need to comprehensively consider these factors and set appropriate winch rotation speed parameters in the control system. For example, in strong winds, the winch rotation speed needs to be appropriately reduced to ensure safe rope release; while under more ideal operating conditions, the speed can be appropriately increased to improve operational efficiency.

[0117] S3. Truss Motion: When the winch rotates, the two-axis truss of the rope cabin will reciprocate back and forth and left and right according to the speed of the winch rotation. This motion is similar to the principle of line winding, and its purpose is to keep the rope smooth during release and avoid problems such as rope compression and tangling. The truss motion is completed by a complex mechanical transmission system and control system working together to ensure its accuracy and stability.

[0118] S4. Automatic Cabin Switching: During the cable laying process, sensors continuously monitor the remaining amount of node rope inside each cabin. When a sensor detects that the node rope inside a cabin has been depleted, it immediately triggers the automatic cabin switching mechanism. The control system responds quickly, stopping the cable laying operation in the current cabin and simultaneously switching the rope to another cabin containing the node rope to continue the cable laying operation, ensuring uninterrupted cable laying.

[0119] S5. Completion of Laying-out Task and Node Rope Fixing: When the laying-out task is completed, the node rope must be fixed promptly. There are several methods for fixing the node rope, the most common being the use of professional rope fixing clamps. Operators need to accurately install the clamps on the end of the node rope to ensure it is secure and reliable, preventing the node rope from loosening or falling off during subsequent use or storage, which could affect the safety and stability of the entire operating system.

[0120] Example 2

[0121] Based on Embodiment 1, both the longitudinal mounting body 303 and the transverse mounting body 403 are provided with at least two bearing wheels 7;

[0122] Each of the aforementioned bearing wheels 7 is rotatably mounted at one of the four corners of the longitudinal mounting body 303 and the transverse mounting body 403;

[0123] The bearing wheel 7 is used to ensure that the longitudinal walking mechanism 3 and the transverse walking mechanism 4 can travel smoothly on the corresponding longitudinal guide rail 301 and transverse guide rail 401.

[0124] Specifically, the load-bearing wheel 7 significantly reduces the friction between the traveling mechanism and the guide rail. Compared to sliding friction, rolling friction has less resistance, allowing the longitudinal traveling mechanism 3 and the transverse traveling mechanism 4 to move more easily and smoothly on their respective guide rails. During long-term operation, the lower friction not only reduces energy loss but also reduces equipment wear, extending the service life of the longitudinal traveling mechanism 3, the transverse traveling mechanism 4, and the guide rails, thus lowering equipment maintenance costs. Moreover, this smooth traveling performance allows operators to more precisely control the speed and stroke of the traveling mechanism, thereby more accurately adjusting the cable deployment position and tension, further improving the quality and efficiency of cable deployment and retrieval operations.

[0125] Example 3

[0126] Based on Embodiments 1 and 2, further, both the longitudinal mounting body 303 and the transverse mounting body 403 are provided with at least two guide wheels 8;

[0127] Each of the guide wheels 8 is respectively mounted on the longitudinal mounting body 303 and the transverse mounting body 403;

[0128] The guide wheel 8 is used for the longitudinal walking mechanism 3 and the transverse walking mechanism 4 to move along the length direction of the corresponding longitudinal guide rail 301 and transverse guide rail 401, and to prevent the longitudinal walking mechanism 3 and the transverse walking mechanism 4 from jumping.

[0129] Specifically, the guide wheel 8 effectively prevents the longitudinal travel mechanism 3 and the lateral travel mechanism 4 from bouncing. When a ship is sailing at sea, it inevitably experiences turbulence, which can cause the travel mechanism to bounce on the guide rails. The presence of the guide wheel 8, through its tight contact with the side of the guide rail, restricts abnormal displacement of the travel mechanism in the direction perpendicular to the guide rail. When the ship is turbulent, the guide wheel 8 can absorb some of the vibration energy, buffering the bouncing tendency of the travel mechanism and ensuring the stability of the longitudinal travel mechanism 3 and the lateral travel mechanism 4 during operation. This stability is crucial for cable retrieval and deployment operations. It avoids sudden changes in cable tension caused by the bouncing of the travel mechanism, reduces the possibility of cable breakage or entanglement due to uneven stress, and further ensures the safe and efficient operation of cable retrieval and deployment.

All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
