Description

Technical Field

[0001] The invention belongs to the technical field of aerospace launch equipment, and in particular relates to an automatic navigation and positioning offshore satellite launch platform. Background Art

[0002] Using a rocket to launch a satellite from land has a long launch distance, high fuel consumption, small carrying capacity, limited orbital entry angle, high risk of success and high cost.

[0003] When a rocket is launched, the combustion of propellant will produce a large amount of toxic and harmful substances, which will affect the living land environment; if the rocket sub-stage falls on the land, it will be dangerous, so the rocket's flight route is subject to considerable restrictions and launch opportunities are limited.

[0004] The equator is the closest place to the geosynchronous orbit, so launching a satellite on the high seas near the equator can maximize the use of the energy of the earth's rotation to increase the rocket's thrust and greatly improve the carrying capacity. At the same time, the rocket flies a short distance, enters the orbit accurately, does not require a secondary orbit change, and saves fuel.

[0005] The high seas near the equator are uninhabited, so launching rockets is not subject to safety restrictions and will not affect the living environment, so the probability of launch is high.

[0006] It is difficult to recover the detached first-stage rocket on land and it cannot be reused.

[0007] Aircraft carriers are limited in tonnage and cannot provide a large platform. They can only use carrier-based aircraft and cannot carry large aircraft such as early warning aircraft and more fighter jets. Aircraft carriers require a large number of ships to sail in a fleet to launch rockets or artificial satellites, which is too expensive. In addition, the cost of manufacturing, using and maintaining aircraft carriers is extremely high.

[0008] Existing offshore satellite launch platforms rarely have the ability to navigate and move automatically, are easily deviated from their predetermined positions on the sea surface, have poor balance, only have a supporting role and a single function, and have great safety hazards. Their structure is not suitable for the requirements of rocket-carrying satellite launches. Summary of the invention

[0043] The wireless transmission module 209 of the present invention adopts a 5G communication wireless transmission module, which is convenient for connecting with the control center set up on the ship to realize remote control of the platform and has an advantage in transmission speed.

[0044] In this embodiment, the wind direction sensor 207 is arranged on the upper side of the control box 2, and the number of cameras 208 is set, and the cameras 208 are respectively arranged on the upper side of the control box 2 and the upper side of the edge of the suspension box 1.

[0045] When the present invention is implemented, the buoyancy of the suspension box 1 is utilized to float on the sea surface, and the rocket for launching the satellite is placed on the upper side of the derrick 18, and the support plate 19 supports the rocket; when the rocket is started, the flame ejected is sprayed on the sea surface on the lower side of the derrick 18; and the casing 13 and the heat insulation layer 14 are used to protect the peripheral structure of the platform; before launching, the support rod 20 and the roller 21 are supported on the lower side of the rocket, and when launching, the electronic control unit ECU204 controls the electric telescopic rod 22 to extend, so that the roller 21 is separated from the side of the rocket;

Therefore, by changing the radius of the suspension box 1 relative to the center of the platform and setting the radius of the suspension box 2 itself, the platform has a stronger impact resistance. The present invention is convenient for adapting to the requirements of rocket launches with different impact resistance requirements.

[0047] When the present invention is used, the platform is first dragged to a predetermined sea area by a large ship, and the position of the platform is adjusted by automatic navigation, so that the influence of the sea surface gas flow and the sea water flow on the position of the platform is reduced.

The solar panels 3 and wind turbines 5 generate electricity and store the electricity in the battery 202 through the wind-solar hybrid controller 201. The battery 202 provides the required power for different electrical components through the inverter 203. In the automatic navigation state, the electronic control unit ECU204 controls the baffle motor 17 to drive the wind deflector 16 parallel to the wind direction according to the wind direction detected by the wind direction sensor 207, thereby reducing the wind resistance of the platform. When the battery 202 is insufficient, the propeller cannot operate, and the baffle motor 17 is used to adjust the angle between the wind deflector 16 and the wind direction to simulate a sailboat and realize the movement of the platform.
