However, existing offshore launch platforms still face significant challenges in stability and vibration control. Especially during rocket launches, vibration control is crucial to ensure the safety and launch accuracy of the rocket.

[0031] The gyroscope 801 is installed at the center of the bottom surface of the stabilizing plate 6 , so that the slight tilt of the stabilizing plate 6 can be monitored and corrected in real time.

[0032] The present invention provides a self-elevating and mobile offshore launch platform, and the specific implementation methods are as follows: The platform includes a vibration-damping plate 1, a rocket support seat 2, a rocket entity 3, a moving plate 4, a vibration isolation mechanism 5, a stabilizing plate 6, a lifting mechanism 7, a stabilizing mechanism 8, a bottom plate 9, a rotating mechanism 10, a carrying hull 11 and a connecting plate 12.

[0033] The vibration isolation mechanism 5 is a key part of the present embodiment, and includes a first damper 501, a first spring 502, a first U-shaped member 503, a first round pin 504, a rotating rod 505, a second round pin 506, a second U-shaped member 507, a sliding rod 508, a fixed stop block 509, a first circular plate 510, a second damper 511, and a second spring 512. These components work together to achieve effective isolation of the vibration generated during the rocket launch process.

[0034] During the implementation, when the vibration generated by the rocket launch is transmitted to the vibration reduction plate 1, the first damper 501 and the first spring 502 first play the role of buffering and absorbing the vibration energy. At the same time, through the linkage of the first U-shaped member 503, the rotating rod 505, the second U-shaped member 507 and other components, the vibration energy is further dispersed and consumed. Finally, through the secondary buffering of the second damper 511 and the second spring 512, it is ensured that the vibration will not cause too much impact on the moving plate 4 and the structure above it.

[0035] Example 2

[0036] like Figure 1 and Figure 2 As shown, based on Example 1, this example further describes in detail the specific implementation of the stabilizing mechanism 8.

[0037] The stabilizing mechanism 8 includes a gyroscope 801 , a tilt sensor 802 , a fourth U-shaped member 809 , a fourth round pin rod 808 , a second swivel seat 807 , a second hydraulic lifting rod 806 , a first swivel seat 805 , a third round pin rod 804 and a third U-shaped member 803 .

[0038] During implementation, when the platform is disturbed by external interference or the reaction force generated by rocket launch causes the stabilizing plate 6 to tilt, the gyroscope 801 and the tilt sensor 802 will quickly detect the tilt angle and direction. Based on these signals, the control system adjusts the length of the four second hydraulic lifting rods 806 to quickly restore the stabilizing plate 6 to a horizontal state. This design ensures the stability of the rocket launch process and effectively improves the success rate of the launch.

[0039] Example 3

[0040] like Figure 1 , Figure 3 , Figure 4 As shown, based on Embodiment 1 and Embodiment 2, this embodiment describes in detail the specific implementation of the lifting mechanism 7.

[0041] The lifting mechanism 7 includes a first hydraulic lifting rod 701, a second circular plate 702 and a connecting rod 703. During implementation, when the launch height of the rocket needs to be adjusted, the control system drives the first hydraulic lifting rod 701 to extend or shorten. Through the transmission action of the second circular plate 702 and the connecting rod 703, the moving plate 4 and the rocket support seat 2 and the rocket entity 3 above it can be smoothly lifted to a suitable height. This design not only improves the flexibility of the launch, but also ensures the stability of the rocket during the launch process.

[0042] like Figure 1-6 As shown, based on Example 1, Example 2, and Example 3, the overall working principle of the present invention is as follows; When the offshore launch platform is in operation, first, the carrier hull 11 is moved to the predetermined launch position through its power system. The rotating mechanism 10 arranged between the carrier hull 11 and the bottom plate 9 allows the bottom plate 9 to be adjusted at an appropriate angle according to the sea conditions to ensure the stability of the platform. Above the bottom plate 9, the stabilizing plate 6 is connected to the bottom plate 9 through the stabilizing mechanism 8. The gyroscope 801 is installed at the center of the bottom surface of the stabilizing plate 6 and can monitor the tilt state of the stabilizing plate 6 in real time. When the platform is disturbed by external interference or the reaction force generated by the rocket launch causes the stabilizing plate 6 to tilt, the gyroscope 801 will detect the tilt angle and direction. The tilt sensor 802 is installed on the upper surface of the stabilizing plate 6 to assist in detecting the tilt of the stabilizing plate 6. When the stabilizing plate 6 tilts, the tilt sensor 802 transmits a signal to the control system. The control system controls the four second hydraulic lifting rods 806 in the stabilizing mechanism 8 to adjust according to the signals of the gyroscope 801 and the tilt sensor 802. Specifically, one end of the second hydraulic lifting rod 806 is rotatably connected to the fourth round pin rod 808 in the fourth U-shaped member 809 through the second rotating seat 807, and the other end is rotatably connected to the third round pin rod 804 in the third U-shaped member 803 through the first rotating seat 805, and the third U-shaped member 803 is fixedly connected to the bottom surface of the stabilizing plate 6. By adjusting the length of the four second hydraulic lifting rods 806, the stabilizing plate 6 can be restored to a horizontal state, thereby ensuring the stability of the rocket launch. When the rocket is ready to launch, the lifting mechanism 7 starts to work. The first hydraulic lifting rod 701 is extended or shortened, and the mobile plate 4 is driven to rise or fall to a suitable launch height through the second circular plate 702 and the connecting rod 703. The lifting mechanism 7 is provided at four locations, respectively located at the four corners of the mobile plate 4, which can ensure that the mobile plate 4 is lifted and lowered smoothly. During the rocket launch process, the rocket support seat 2 and the rocket entity 3 on the vibration damping plate 1 will be subjected to strong vibration, and the vibration is first transmitted to the vibration damping plate 1. The vibration damping plate 1 absorbs and buffers part of the vibration energy through the first damper 501 and the first spring 502. The first damper 501 can consume vibration energy and reduce the transmission of vibration, while the first spring 502 can alleviate the impact of vibration through elastic deformation. At the same time, the vibration damping plate 1 drives the first U-shaped member 503 to move, and the first round pin rod 504 in the first U-shaped member 503 causes the rotating rod 505 to rotate. The rotation of the rotating rod 505 drives the second U-shaped member 507 to move through the second round pin rod 506, and the second U-shaped member 507 pushes the sliding rod 508 to slide in the fixed limit block 509. During the movement, the first circular plate 510 at one end of the sliding rod 508 further absorbs and buffers the vibration energy through the second damper 511 and the second spring 512. The second damper 511 consumes vibration energy, and the second spring 512 alleviates the impact through elastic deformation, thereby reducing the impact of vibration on the movable plate 4 and the upper structure. This double shock absorption design significantly improves the vibration isolation effect and ensures the stability and safety during the rocket launch.The vibration isolation mechanism 5 is provided at four locations, respectively located at the four corners between the vibration damping plate 1 and the movable plate 4, which can effectively reduce the transmission of vibration from multiple directions. In summary, the present invention not only retains the mobility and self-lifting functions through innovative vibration isolation design, combined with the stabilizing mechanism and the lifting mechanism, but also effectively reduces the negative impact of vibration on the rocket during the rocket launch process, and significantly improves the stability and safety of the sea launch.
