Description

Technical Field

[0001] The invention belongs to the technical field of offshore rocket launching platform structures, and in particular is a self-propelled offshore rocket launching platform structure. Background Art

[0002] With the continuous advancement of global aerospace technology, rocket launches, as a key link in entering space, are also constantly innovating and evolving in terms of technology. Although traditional land-based rocket launches have a long history and mature technology, they are still inevitably subject to geographical restrictions, strict constraints on launch time windows, and considerations of the impact on the safety of surrounding residential areas. These factors restrict the flexibility and efficiency of rocket launches to a certain extent.

[0003] In order to break through the above limitations, sea-based rocket launch technology has gradually emerged and become a research hotspot in the global aerospace field. With its unique advantages, such as flexible selection of launch sites, minimal impact on residential areas, and more effective use of the power provided by the Earth's rotation, sea-based launch technology provides new possibilities for rocket launches.

It is fixedly connected to the bottom surface of the rocket launching platform 2.

[0057] Through the design of the retractable mechanism 3, the rocket launching platform 2 can be effectively stored when no launching mission is carried out. Specifically, when the ship 1 is in a sailing state, the first screw 303 is driven to rotate by the servo motor 302, thereby driving the first deck 307 and the second deck 309 to slide in the slide groove 344, and finally the rocket launching platform 2 is completely stored inside the deck of the ship 1. This design significantly reduces the wind resistance of the rocket launching platform 2 during sailing, thereby reducing unnecessary energy consumption.

[0058] Through the sophisticated mechanical transmission system design, not only the storage function of the rocket launch platform 2 is realized, but also the flexibility and overall efficiency of the launch system are significantly improved. Specifically, under the drive of the servo motor 302, the rotation of the first screw rod 303 not only drives the opening and closing of the deck, but also synchronously controls the lifting and lowering of the rocket launch platform 2 through the linkage of a series of pulleys and screw rods.

[0059] like Figure 1-5 As shown, the overall working principle of the present invention is as follows:

[0060] When using the present invention, first start the servo motor 302. The output end of the servo motor 302 drives the first screw rod 303 to rotate inside the screw rod square tube 301. Since the outer surface of the first screw rod 303 is threadedly connected with the first slider 304 and the second slider 305, and the two sliders are in sliding contact with the inner wall of the screw rod square tube 301, when the first screw rod 303 rotates, the first slider 304 and the second slider 305 will move closer to or away from each other accordingly. Under the drive of the servo motor 302, when the first slider 304 and the second slider 305 move away from each other, the first slider 304 pushes the first deck 307 to slide to the right inside the chute 344 through the first connecting rod 306, and the second slider 305 drives the second deck 309 to slide to the left inside the same chute 344 through the second connecting rod 308. This process continues until the first deck 307 and the second deck 309 are completely received inside the chute 344. It is worth noting that during the opening or storage process of the first deck 307 and the second deck 309, the rocket launch platform 2 also performs a lifting operation synchronously. The realization of this coordinated action depends on a sophisticated mechanical transmission design. Specifically, when the first screw 303 rotates, the first bevel gear 316 fixed at one end thereof close to the first rotating shaft 317 also rotates accordingly, thereby driving the second bevel gear 318 on the outer surface of the first rotating shaft 317 meshing with the first bevel gear 316 to rotate. Thus, by the rotation of the first rotating shaft 317, the entire retracting mechanism 3 is activated and starts to operate. Further, a first pulley 319 is fixed to the top of the first rotating shaft 317. When the first rotating shaft 317 rotates, the first pulley 319 drives the second pulley 320 to rotate through the first belt 321. Subsequently, the rotation of the second pulley 320 is transmitted to the third pulley 325 through the second rotating shaft 322. Similarly, the third pulley 325 drives the fourth pulley 326 to rotate through the second belt 327. This series of pulley transmissions continues until the eighth pulley 338 is finally driven to rotate, ensuring that the rocket launch platform 2 can fit tightly with the deck of the ship 1 after the first deck 307 and the second deck 309 are stored. In this series of transmission processes, the rotation of each pulley drives the screw tube threadedly connected thereto to move up and down through its corresponding screw. This design ensures the stability and synchronization of the rocket launch platform 2 during the storage process, thereby achieving the stable storage of the entire rocket launch platform 2. When it is necessary to store the rocket launch platform 2 after launch, this principle is also followed. Through the working principle elaborated in detail above, the present invention can not only effectively store the rocket launch platform 2 in the non-launching state, reduce the wind resistance and energy consumption of the platform during navigation, but also significantly improve the flexibility and overall efficiency of the launch system. At the same time, through the carefully designed mechanical transmission mechanism, the present invention ensures the stability and reliability of the storage process, thereby meeting the stringent requirements of the offshore rocket launch platform in practical applications.
