Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ships, in particular to a multifunctional autonomous semi-submersible ship. BACKGROUND

[0002] Nowadays, the marine transportation industry is related to the fate of the national economic development (70% of global goods trade relies on marine ship transportation), and the variability of marine climate and the severity of sea conditions limit the development of marine ships and the marine transportation industry, causing problems such as difficulty in transporting large marine cargo, high risk of seafarer work, and high ship operation cost. In addition, the rocket recovery related to the comprehensive national strength faces the development bottleneck of great technical difficulty and high cost. From the development trend of foreign space powers, since the ocean area is very wide, the realization of rocket recovery at sea can reduce the landing safety risk and greatly reduce the recovery cost.

[0003] The existing semi-submersible ship technology is designed to load large marine cargo, generally designed to maximize the loading deck area, and can achieve different draft changes by injecting and discharging ballast water, while having a dynamic positioning system and a propulsion system, which can accurately move to the bottom of the cargo to realize the loading and transportation function of large marine cargo. Semi-submersible ships generally use alternating current power propulsion, shaft propeller transmission and other technologies, equipped with multiple fuel generators to provide power for the whole ship, and the environmental protection level is affected by the nature of fuel. The existing semi-submersible ship needs to be equipped with dozens of crew members for daily operation, and has no autonomous function.

[0004] Since the existing semi-submersible ship technology is not a full-rotation dynamic positioning system, it is difficult to withstand the impact force brought by the rocket recovery landing. And for the rocket recovery function, a high-level dynamic positioning ship with a larger barrier-free deck area is needed, and high-temperature resistant materials are laid on the deck surface.

[0005] The existing semi-submersible ship technology has a single design function, which is not conducive to diversified operation. Since the amount of large marine cargo is relatively small, the utilization rate of the ship is low, and the added value is not high; the degree of autonomy is low, a large number of crew members are needed, and the operation labor cost is high; the ship carries many equipment, the system is complex, and the maintenance cost is high; the fuel power propulsion system has poor energy saving and emission reduction effect, and the environmental protection performance is general.

[0061] The high-temperature-resistant material layer on the outer side of the upper photovoltaic panel has a high-temperature-resistant material, which can enable the recovery platform to withstand the high temperature generated by the rocket flame during rocket recovery. The high-temperature-resistant material layer is laid on the back of the upper photovoltaic panel to form a high-temperature-resistant material layer. When the upper photovoltaic panel is closed, the high-temperature-resistant material layer is the top surface of the middle section of the main deck.

[0062] The middle section of the main deck is provided with an electromagnetic adsorption device (not shown in the figure) that can adsorb metal objects. The electromagnetic adsorption device belongs to the existing component, which will not be described here. The electromagnetic adsorption device can realize the functions of fixing and loading large goods.

[0064] When the multifunctional autonomous semi-submersible ship is used for rocket recovery, the flight trajectory and the expected landing point of the rocket are obtained from the rocket control center, and the landing point is reached in advance. The key signals such as wind speed, wind direction, sea water flow rate and flow direction are transmitted to the control center on the ship by various sensors on the ship, and after analysis, the control signals are transmitted to the thrusters, and the real-time dynamics of the rocket are obtained through data exchange with the space center, so that the swing amplitude and positioning accuracy of the ship are controlled within a certain range. After the rocket lands, the electromagnetic adsorption device on the deck of the ship firmly fixes the rocket on the deck of the ship, replacing the manual welding fixing mode.

[0065] The ship has multiple functions such as transportation of large marine cargo, marine rocket recovery platform, etc., and has the characteristics of diversification and autonomous operation. Autonomous design greatly saves the cost of crew manpower. The electromagnetic adsorption device used by the ship solves the problem of automatic fixing and loading of large marine cargo. The design of high-temperature resistant material and advanced dynamic positioning system on the deck surface ensures the stability and safety of the landing of the marine rocket recovery.

[0066] The ship uses a green power system (battery + super capacitor + photovoltaic), which can effectively improve the environmental performance and has relatively small installation space. At the same time, four pod thrusters are equipped to form a vector propulsion system, which can realize "two-drive" and "four-drive" propulsion mode, ensuring the efficiency of the speed.
