[0027] This specific embodiment is a four-pile guide frame, and its structural schematic diagram is as follows: Figure 1-6 As shown, the device includes a base 1, a stabilizing structure 2 at the center of the upper surface of the base 1, a supporting platform 3 at the center of the upper surface of the stabilizing structure 2, a conduit structure 4 at the center of the upper surface of the supporting platform 3, a connecting plate 5 at the center of the upper surface of the conduit structure 4, and an installation structure 6 at the center of the upper surface of the connecting plate 5.

[0028] First, in this embodiment, the specific structure of the stabilizing structure 2 is as follows: The stabilizing structure 2 includes four first rotating frames 201, which are respectively located at the four opposite corners of the upper end face of the base 1. A first rotating ball 202 is rotatably connected to the center of each of the four first rotating frames 201. A first stabilizing rod 203 is provided at the center of the upper end face of each of the four first rotating balls 202. One end of each of the four first stabilizing rods 203 is fixedly connected to the four opposite corners of the lower end face of the support platform 3. The four first rotating frames 201 are located at the four opposite corners of the upper end face of the base 1, and the first rotating ball 202 is rotatably connected to the center of the inner part of each first rotating frame 201. 02. When the support platform 3 is subjected to external forces from different directions and causes swaying or slight displacement, the first rotating ball 202 can rotate flexibly within the first rotating frame 201, playing a role in buffering and fine adjustment, so that the first stabilizing rod 203 always maintains a good support state. The support platform 3 is connected to the base 1 through the first stabilizing rod 203. Due to the cooperation of the first rotating ball 202 and the first rotating frame 201, when the support platform 3 has a tendency to sway, the first stabilizing rod 203 adapts to the position change of the support platform 3 through the rotation of the first rotating ball 202, preventing the support platform 3 from swaying excessively, and playing a role in stabilizing the position of the platform.

[0029] Furthermore, a second rotating frame 204 is provided at the center of the upper end face of the base 1 and the center of the lower end face of the support platform 3. A second rotating ball 205 is provided at the center of the interior of each of the two second rotating frames 204. A second stabilizing rod 206 is provided between the two second rotating balls 205. The upper end faces of both the base 1 and the support platform 3 are inclined and have four grooves 207 arranged in a rectangular shape. The second rotating frame 204, the second rotating ball 205 and the second stabilizing rod 206 between the base 1 and the support platform 3 further enhance the overall stability. The second rotating ball 205 rotates within the second rotating frame 204. When the base 1 When the support platform 3 has an angle change or slight displacement, the second stabilizing rod 206 can adjust its own angle and position by rotating the second rotating ball 205, and work with the first rotating frame 201 to better maintain the stability of the support platform 3 relative to the base 1. The upper surfaces of the base 1 and the support platform 3 are both inclined and have four grooves 207 arranged in a rectangle. The grooves 207 can guide the flow and reduce the impact of the fluid on the platform. When the fluid impacts the platform, the grooves 207 will change the flow direction of the fluid and disperse the fluid force, thereby reducing the impact force on the whole, which is conducive to the stability of the entire device in the marine environment.

[0030] Then, the conduit structure 4 includes four conduit mounting posts 401, which are respectively located at the four opposite corners of the upper end face of the support platform 3. Each of the four conduit mounting posts 401 has a conduit frame 402 at its center. Four first support rods 403 are arranged vertically and horizontally between the lower center of one side wall, the lower center of the rear end face of two of the front conduit frames 402, and the lower center of the front end face of two of the rear conduit frames 402. The conduit mounting posts 401 are respectively located at the four opposite corners of the upper end face of the support platform 3 to fix the conduit frames 402 and secure the upper structure. The weight and external force of the structure are transmitted to the support platform 3, and then from the support platform 3 to the base 1 and the seabed. The first support rod 403 and the second support rod 404 are intersected between the jacket 402. In the dynamic environment at sea, the jacket 402 will be subjected to loads in various directions. The intersecting support rods can enhance the connection strength between the jacket 402 and the stability of the overall structure. When a jacket 402 is subjected to external force, the first support rod 403 and the second support rod 404 can distribute the force to other jacket 402, preventing a local jacket 402 from being damaged due to excessive force.

[0031] Furthermore, four second support rods 404 are arranged in a crisscross pattern between the upper center of one side wall of the four jacket supports 402, the upper center of the rear end face of the two front jacket supports 402, and the upper center of the front end face of the two rear jacket supports 402. Each of the eight first support rods 403 has a handle at the center of its upper and lower end faces. The handles are mainly used as leverage points for workers to perform maintenance, repairs, and equipment installation on the jacket supports 402 and related components. This facilitates climbing and gripping by workers, ensuring their safety in the swaying platform environment at sea and making it easier to carry out related work.

[0032] The installation structure 6 includes a connecting frame 601, which is located at the center of the end face of the connecting plate 5. The outer wall of the connecting frame 601 has four through holes 602 arranged in a ring. The through holes 602 are used to connect with other equipment or structures that need to be installed on the top of the jacket frame 402. Some offshore operation equipment, signaling devices, and subsequent possible expansion structures are fastened by bolts or other connectors through the through holes 602, so as to realize the stable connection between the jacket frame 402 and other equipment and expand the functional application range of the jacket frame 402 in offshore operations.

[0033] Secondly, a ladder 405 is provided at the center of one side wall of the jacket 402 near the front, and a second platform 406 is fitted at the upper center of the outer side wall of the jacket 402 near the front. The ladder 405 and the second platform 406 provide a passage for workers to climb from a lower position to a higher position, making it convenient for workers to climb from near the sea surface to the working area on the second platform 406 or the top of the jacket 402. This facilitates the movement of personnel between different heights on the platform to carry out equipment inspection and maintenance. The second platform 406 serves as an area for workers to rest, temporarily store tools, and perform some equipment operation and inspection. Standing on the second platform 406, workers can observe and operate the surrounding equipment more closely. It works in conjunction with the ladder 405 to meet the needs of convenient passage and personnel rest between different height working areas in the vertical direction.

[0034] Finally, a first platform 603 is provided at the center of the upper end face of the connecting frame 601, and a guardrail 604 is provided on the outer side of the center of the upper end face of the first platform 603. The first platform 603 and the guardrail 604 provide personnel with a flat area for operation, monitoring and communication activities at the top of the jacket 402. Personnel can operate equipment, send and receive signals, and observe the surrounding marine environment on this platform. It is an important working platform at the top of the jacket 402. The guardrail 604 can prevent personnel from falling from the edge of the first platform 603 due to platform shaking, accidental slipping or collision, etc., and ensure the personal safety of personnel working on the first platform 603, so that personnel can safely perform various operations on the platform.

[0035] When using the device of this technical solution, when the support platform 3 is shaken or slightly displaced by external force, the first rotating ball 202 can rotate within the first rotating frame 201 to buffer and finely adjust its position, so that the first stabilizing rod 203 remains in a supporting state, preventing the support platform 3 from shaking excessively. When the base 1 or the support platform 3 has an angle change or slight displacement, the second stabilizing rod 206 adjusts its own angle and position through the rotation of the second rotating ball 205, and works with the first rotating frame 201 assembly to maintain the stability of the support platform 3 relative to the base 1. The groove 207 can play the role of guiding the flow and reducing the impact of the fluid on the platform. When the fluid impacts the platform, the groove 207 changes the direction of the fluid flow, disperses the force, reduces the impact force on the device, and is conducive to the stability of the device in the marine environment.

[0036] Four guide pipe mounting columns 401 are used to fix the jacket 402, transferring the weight and external force of the superstructure to the support platform 3, and then from the support platform 3 to the base 1 and the seabed. The first support rod 403 and the second support rod 404 are arranged crosswise between the jacket 402. In the dynamic environment at sea, the jacket 402 will be subjected to loads in various directions. The crosswise arrangement of the support rods can enhance the connection strength between the jacket 402 and the stability of the overall structure.

[0037] When a jacket 402 is subjected to external force, the first support rod 403 and the second support rod 404 can distribute the force to other jacket 402s, preventing damage to a particular jacket 402 due to excessive force. The handles primarily serve as leverage points for workers when inspecting, maintaining, and installing equipment on the jacket 402 and its related components, facilitating climbing and gripping, ensuring worker safety in the swaying platform environment at sea, and enabling better performance of related work. The ladder 405 and the second platform 406 provide workers with access from lower positions. The access to higher positions allows staff to easily climb from near the sea surface to the working area on top of the second platform 406 or the jacket 402, facilitating movement between different platform heights for equipment inspection and maintenance. The second platform 406 serves as a rest area for staff, a temporary storage area for tools, and a space for some equipment operation and inspection. Standing on the second platform 406, staff can observe and operate the surrounding equipment more closely. Together with the ladder 405, it facilitates convenient passage and staff rest between different working areas at different vertical heights.

[0038] Through-hole 602 is used to connect with other equipment or structures that need to be installed on the top of the jacket 402. Some offshore operation equipment, signaling devices, and subsequent possible expansion structures are fastened by bolts or other connectors through through-hole 602, realizing a stable connection between the jacket 402 and other equipment, and expanding the functional application range of the jacket 402 in offshore operations. The first platform 603 and guardrail 604 provide personnel with a planar area at the top of the jacket 402 for operation, monitoring and communication activities. Workers can operate equipment, send and receive signals, and observe the surrounding marine environment on this platform. It is an important working platform at the top of the jacket 402. The guardrail 604 can prevent workers from falling from the edge of the first platform 603 due to platform shaking, accidental slipping or collision, etc., ensuring the personal safety of personnel working on the first platform 603 and enabling personnel to safely perform various operations on the platform.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
