The existing offshore platforms have their legs set vertically to the platform body, which makes it impossible to adjust their attitude according to different working conditions. This results in the overall center of gravity shifting upward, increasing wind resistance, and making them unstable when moving.

Combined with a lifting and locking device and a hydraulic impact device, the rotation and locking of the pile leg are realized. The pile leg can be folded to lower the center of gravity, and the pile leg can be set vertically to stabilize the platform.
By reducing wind resistance during movement, the stability and applicability of the platform are improved. The legs can adjust their posture according to working conditions to achieve smooth navigation and stable erection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of offshore platform technology, and specifically to an offshore platform. Background Technology
[0002] An offshore platform is a mobile working platform used for offshore construction operations. It consists of a platform body and legs. The legs are mounted on the platform body and are used for positioning and supporting the offshore platform during construction, maintaining its stability. When the offshore platform needs support, the legs extend down to the seabed; when the offshore platform needs to move, the legs must be raised above the platform. This causes the overall center of gravity of the offshore platform to shift upward and increases wind resistance. In addition, the legs of the offshore platform are generally set perpendicular to the platform body, and the posture of the legs cannot be adjusted according to different working conditions.
[0003] In conclusion, there is an urgent need to provide an offshore platform to address the problems existing in the current technology. Utility Model Content

[0033] Example
[0034] See Figure 1 This embodiment provides an offshore platform, including a platform body 1. Multiple leg mechanisms are disposed on the platform body 1. Preferably, the multiple leg mechanisms are evenly distributed on the left and right sides of the platform body 1. Each leg mechanism includes a leg 2 and a leg rotation mechanism 3. The leg 2 is mounted on the leg rotation mechanism 3, which is connected to the platform body 1 and drives the leg 2 to rotate relative to the platform body 1. When the offshore platform needs to move, the leg rotation mechanism 3 drives the leg 2 to rotate relative to the platform body 1. (See also...) Figure 1 The angle between the second leg and the platform body becomes smaller, and the legs fold, which lowers the overall center of gravity of the platform, reduces wind resistance, and makes the offshore platform move more smoothly.
[0035] See Figure 2 The pile leg rotation mechanism 3 includes a rotating housing 3.1 and a rotation drive mechanism 3.2. The pile leg 2 is disposed through the rotating housing 3. The rotating housing 3.1 is rotatably connected to the platform body 1. Preferably, the rotating housing 3.1 and the platform body 1 are connected by a pin. The rotation drive mechanism 3.2 connects the rotating housing 3.1 and the platform body 1 and is used to drive the rotating housing 3.1 to rotate relative to the platform body 1. Preferably, the rotation drive mechanism 3.2 includes a rotating cylinder. The fixed end of the rotating cylinder is connected to the platform body 1 through a hinged support 3.3, and the telescopic end of the rotating cylinder is connected to the rotating housing 3.1 through another hinged support 3.3.
[0036] In this embodiment, preferably, the platform body 1 is provided with a through hole for setting the pile leg mechanism, and the inner contour shape of the through hole matches the rotation path of the rotating box 3.1.
[0037] In this embodiment, see Figure 2 The pile leg 2 tilts to the left under the drive of the rotating hydraulic cylinder, and the left end of the through hole is provided with an inclined surface, which matches the pile leg 2 tilting to the left.
[0038] In this embodiment, a lifting and locking device 4 is also provided between the pile leg 2 and the rotating box 3. The lifting and locking device 4 is used to realize the lifting and locking of the pile leg 2 and the platform body 1. The lifting and locking device 4 adopts existing technology, such as gear and rack structure.
[0039] See Figure 3 In this embodiment, the pile leg 2 includes an outer pile cylinder 2.1 and an impact pile 2.2 disposed inside the outer pile cylinder 2.1. The impact pile 2.2 is slidably connected to the outer pile cylinder 2.1, and a limiting device is also provided between the impact pile 2.2 and the outer pile cylinder 2.1 to prevent the impact pile 2.2 from sliding out of the outer pile cylinder 2.1. A hydraulic impact device 5 is disposed inside the outer pile cylinder 2.1, and the hydraulic impact device 5 is used to impact the impact pile 2.2. In this embodiment, the hydraulic impact device 5 adopts a hydraulic impact hammer, and the pile driving action is realized by the hydraulic impact hammer.
[0040] In this embodiment, see Figure 1 The platform body 1 is also provided with a flip-up mechanism 6, which is located at the end of the platform body 1; the flip-up mechanism 6 can quickly connect with the shore, dock or other platforms.
[0041] See Figure 4 and Figure 5The flip-plate mechanism 6 includes a flip-plate base 6.1 and a flip-plate 6.2. The flip-plate base 6.1 is connected to the platform body 1, and the flip-plate 6.2 is hinged to the flip-plate base 6.1. Preferably, the flip-plate 6.2 includes a primary flip-plate 6.2.1 and a secondary flip-plate 6.2.2. One end of the primary flip-plate 6.2.1 is hinged to the flip-plate base 6.1, and the other end of the primary flip-plate 6.2.1 is hinged to the secondary flip-plate 6.2.2. A first driving mechanism 6.3 is provided between the primary flip-plate 6.2.1 and the flip-plate base 6.1.
[0042] The first driving mechanism 6.3 includes a primary hydraulic cylinder 6.3.1 and a secondary hydraulic cylinder 6.3.2. The fixed end of the primary hydraulic cylinder 6.3.1 is connected to the flip plate base 6.1, and the fixed end of the secondary hydraulic cylinder 6.3.2 is connected to the primary flip plate 6.2.1. The telescopic ends of both the primary and secondary hydraulic cylinders 6.3.1 and 6.3.2 are hinged to a relay connecting block 6.3.3, which is hinged to a hinge seat on the platform body 1. The expansion and folding of the primary flip plate 6.2.1 are achieved through the telescopic movement of the primary hydraulic cylinder 6.3.1 and the secondary hydraulic cylinder 6.3.2.

One end of the steel wire rope is connected to the telescopic end of the tensioning cylinder 6.4.1, and the other end of the steel wire rope is wound around the rope wheel 6.4.2. When the tensioning cylinder 6.4.1 retracts, the steel wire rope tightens, driving the rope wheel 6.4.2 to rotate, which in turn drives the second-stage flip plate 6.2.2 to rotate, realizing the unfolding of the second-stage flip plate 6.2.2. When the tensioning cylinder 6.4.1 extends, the steel wire rope loosens, and the second-stage flip plate 6.2.2 folds under its own weight.
[0044] See Figure 1 In this embodiment, the offshore platform also includes a float 7, a propulsion device 8, and a control room 9. The float 7 is disposed on both sides of the platform body 1 to improve the buoyancy of the platform body 1.

Under the action of the lifting and locking device 4, the pile leg 2 extends to the seabed surface and is driven into a pile by the hydraulic impact device 5 to stabilize the entire platform. After the pile leg 2 is fixed, the platform body 1 is lifted to the designated position and locked by the lifting and locking device 4 to complete the platform erection. The flip plate 6.2 of the flip plate mechanism 6 can be unfolded or folded according to the actual application.
