Description

Technical Field

[0001] The present invention relates to the technical field of deep - sea mineral exploitation, and specifically to a floating platform device for deep - sea minerals. Background Art

[0002] With the continuous growth of global resource demand, the development of land mineral resources is gradually facing problems such as resource depletion and rising exploitation costs. Deep - sea mineral resources, due to their rich reserves and diverse types, have become an important direction for future resource development. However, the deep - sea environment is complex and changeable, with high water pressure, strong water currents, low temperatures, and severe sea conditions, which pose great challenges to deep - sea mineral exploitation. Traditional floating platform devices have many deficiencies in deep - sea mineral exploitation. On the one hand, their structural strength and stability are difficult to meet the requirements of the complex deep - sea environment, and they are prone to shaking, tilting, or even displacement due to wave impacts, water current actions, or load changes, affecting the accuracy and safety of mineral exploitation. On the other hand, the buoyancy adjustment ability of traditional floating platforms is limited, and they cannot adjust the buoyancy in real - time according to different load conditions and sea conditions, resulting in the floating platform being difficult to maintain the best working state during the exploitation process. In addition, the efficiency of the mineral collection and storage system is low, and it is easy to cause losses of minerals during the collection and transportation processes, further reducing the exploitation efficiency.

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0014] 1. Multi-layer structure design: The main body of the floating platform adopts a multi-layer structure consisting of an upper deck, a middle support frame, and a lower floating body. The layers are welded and fixedly connected by high-strength steel, forming an integral whole, enhancing the structural strength and stability of the floating platform. The middle support frame is welded by high-strength steel, which can effectively bear the weight of the upper deck and mineral extraction equipment, and at the same time evenly transfer the force to the lower floating body, avoiding structural deformation caused by excessive local stress.

[0015] 2. Setting of the buffer mechanism: A buffer mechanism is set between the lower floating body and the middle support frame. When the floating platform is impacted by sea waves or water currents, it can effectively absorb and buffer the impact force, reduce the swaying and displacement of the floating platform, and maintain the stable operation of the floating platform. The positioning plate enables the buffer mechanism to maintain the structural stability and reliability while absorbing the impact force, further enhancing the durability and safety of the floating platform. The buffer absorbs and disperses the force through multi-point hinges when subjected to external impact, and has good buffer reset ability; the spring is sleeved on the sliding rod, with a compact structure and rapid response, which can effectively cope with sudden wave impacts and significantly improve the seismic performance and operation reliability of the entire floating platform device.

[0016] 3. Design of the auxiliary floating body and floating bridge: The auxiliary floating body and floating bridge set at the bottom of the lower floating body increase the buoyancy reserve of the floating platform, enabling the floating platform to have better buoyancy balance performance in the deep sea and further improving the stability of the floating platform. The auxiliary floating body is filled with low-density foam material inside and wrapped with high-strength anti-corrosion material outside, ensuring both buoyancy and enhanced durability.

[0017] 4. Precise control of the buoyancy adjustment mechanism: By adjusting the opening and closing of the air inlet pipe and exhaust pipe, the gas pressure in the buoyancy adjustment chamber can be precisely controlled, thereby realizing the dynamic adjustment of the buoyancy of the floating platform. During the mineral extraction process, the buoyancy can be adjusted in real time according to the load condition of the floating platform and the sea conditions, maintaining the optimal working state of the floating platform and improving the mineral extraction efficiency.

[0018] 5. Anchor chain fixing system: Multiple first anchor chains are set on the lower floating body, and multiple second anchor chains are set inside the extension column. These anchor chains are fixedly connected to the seabed foundation, which can effectively limit the horizontal displacement of the floating platform, ensure the stability of the floating platform in complex deep-sea conditions, prevent the floating platform from drifting due to the action of wind, waves or water currents, and guarantee the safe operation of the floating platform.

[0019] In summary, this deep-sea mineral floating platform adopts a multi-layer structure and high-strength steel to enhance the overall stability. The buffer mechanism effectively absorbs the impact force and enhances the seismic performance. The auxiliary floating body and floating bridge increase the buoyancy reserve and improve the balance. The buoyancy adjustment mechanism realizes dynamic control, and the multiple anchor chain systems ensure the stability of the device and prevent drifting, comprehensively improving the safety and reliability of deep-sea mining.

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] Example: Refer to Figures 1 to 6 A floating platform device for deep-sea minerals includes a floating platform body 1, which includes an upper deck 101, a middle support frame 102 and a lower buoy 103. The floating platform body 1 serves as the core bearing structure of the entire system, and a support frame 2 and a mineral mining device 3 are arranged on its upper part for installing and operating mineral collection equipment. The upper deck 101 is an operating platform, and its bottom is fixedly connected to the middle support frame 102 by welding with high-strength steel, thereby forming a stable and reliable load-bearing skeleton. The lower buoy 103 is located at the bottom of the entire structure, bears the main buoyancy function, and is connected to the middle support frame 102 through a buffer mechanism 4 to absorb the impact force from the marine environment.

[0031] The upper deck 101 is fixedly connected to the secondary platform 6 via four support columns 5. A mineral collector 7 is provided on the upper deck 101, which is responsible for collecting the minerals collected by the mineral mining device 3 and transporting them to the mineral storage bin 8 inside the lower floating body through a conveying pipeline. The mineral storage bin 8 is arranged in the upper body 1031 of the lower floating body for temporary storage of mineral resources, and a discharge pipe 13 is provided at the bottom thereof, which runs through the upper body 1031 for subsequent transportation and recovery.

[0032] The lower floating body 103 adopts a split design, including an upper body 1031 and a lower floating body 1033, which are connected by multiple connecting rods 1032 to maintain the integrity and strength of the structure. A buoyancy adjustment mechanism 9 is provided inside the lower floating body 1033, which includes a buoyancy adjustment chamber 91, an air intake pipe 92, an exhaust pipe 93 and multiple buoyancy units 94. By controlling the air intake and exhaust, the gas pressure in the buoyancy adjustment chamber can be dynamically adjusted to achieve precise control of the buoyancy of the entire floating platform, so that it can adapt to different mining loads and marine conditions to ensure smooth operation.

[0033] Two floating bridges 1034 are provided at the bottom of the lower buoy 1033, and an auxiliary buoy 10 is provided. The auxiliary buoy 10 is filled with low-density foam material and wrapped with high-strength anti-corrosion material on the outside, which not only improves the overall buoyancy reserve, but also enhances the corrosion resistance and service life. An extension column 1035 is provided at the center of the bottom of the lower buoy, and multiple second anchor chains are arranged inside it, which are combined with multiple first anchor chains 11 on the lower buoy 103 to anchor to the seabed foundation together to prevent the floating platform from drifting due to wind and waves or ocean currents.

[0034] The buffer mechanism 4 includes an upper buffer plate 41, a lower buffer plate 42, a buffer 43, and a buffer spring 45. The upper buffer plate 41 is fixedly connected to the middle-layer support frame 102, and the lower buffer plate 42 is fixed on the lower floating body 103. The two are connected by a plurality of buffers 43. Inside the buffer 43, there are a slide bar 431, a disc 432, a first connecting rod 433, a ring 434, a second connecting rod 435, and a spring 436. Through the synergistic effect of the hinge structure and the elastic element, it effectively disperses and absorbs the impact force from the sea waves or ocean currents, improving the stability and safety of the floating platform under harsh sea conditions. There is a guardrail 14 at the edge of the upper deck 101, and a protective net 15 at the bottom of the lower floating body 103.

[0035] The working principle of the present invention is as follows:

[0036] The entire device consists of a floating platform main body 1, which includes an upper deck 101, a middle-layer support frame 102, and a lower floating body 103. The upper deck 101 serves as the main working platform, carrying a mineral extractor 3, a mineral collector 7, and a secondary platform 6. The secondary platform is fixedly connected to the deck by four support columns 5, further expanding the equipment layout space. The middle-layer support frame 102 is welded with high-strength steel, having good load-bearing capacity and anti-deformation ability, and can evenly transfer the upper load to the lower floating body 103, thereby enhancing the stability of the overall structure.

[0037] The lower floating body 103 is the key buoyancy system of the device, consisting of an upper main body 1031 and a lower floating body 1033. The two are connected by a plurality of connecting rods 1032 to form a stable spatial structure. Inside the upper main body 1031, there is a mineral storage bin 8 for temporarily storing the mineral resources collected from the seabed, and it is connected to the mineral collector 7 through a conveying pipeline to achieve efficient transmission of minerals; while the discharge pipeline 13 penetrates the upper main body, facilitating the centralized recovery of minerals in the later stage. Inside the lower floating body 1033, there is a buoyancy adjustment mechanism 9, which includes a buoyancy adjustment chamber 91, an air inlet pipe 92, an exhaust pipe 93, and a plurality of buoyancy units 94. By controlling the gas inlet and outlet to adjust the pressure in the chamber, the dynamic adjustment of the overall buoyancy is realized. This design enables the floating platform to adjust its own buoyancy in real time according to the actual load changes and the changes in the marine environment, maintaining the best operating state.

[0038] In order to improve the seismic resistance and stability of the system, a buffer mechanism 4 is installed between the middle support frame 102 and the lower floating body 103. The mechanism consists of an upper buffer plate 41, a lower buffer plate 42, a buffer 43 and a buffer spring 45, wherein the buffer 43 adopts a hinged structure, through the joint action of the slide rod 431, the disc 432, the first connecting rod 433, the ring 434 and the second connecting rod 435, the spring 436 is used to absorb the impact energy and achieve rapid reset, thereby effectively alleviating the impact force brought by the waves or water flow, and ensuring the smooth operation of the upper structure. In addition, the design of the positioning plate 44 also enhances the guidance and stability of the buffer mechanism 4 when it is under force.

[0039] In order to improve the buoyancy reserve and stability, an auxiliary buoy 10 and two floating bridges 1034 are also set at the bottom of the lower buoy. The auxiliary buoy 10 is filled with low-density foam material inside and wrapped with high-strength anti-corrosion material outside, which not only ensures the additional buoyancy requirements but also improves durability. The extension column 1035 is located at the center of the bottom of the lower buoy. It is equipped with multiple second anchor chains inside. Combined with the multiple first anchor chains 11 on the lower buoy 103, it is connected to the fixed point on the seabed to form a multiple anchoring system to prevent the device from drifting due to wind and waves or ocean currents, thereby ensuring the precise positioning of the floating platform in the deep sea.

[0040] The entire device is also equipped with a guardrail 14 at the edge of the upper deck to ensure the safety of the staff; a protective net 15 is provided at the bottom of the lower floating body to prevent small marine organisms from entering and affecting the operation of the equipment, while also playing a certain protective role.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
