Description

Technical Field

[0001] The invention relates to the technical field of water environment mining engineering, and in particular to a floating self-adaptive seabed nodule mineral collection system. Background Art

[0002] As global demand for resources continues to grow, the exploration and exploitation of seabed resources has become a new strategic focus. The seabed is not only rich in oil and natural gas, but also contains unique mineral resources, such as polymetallic nodules. These nodules are rich in key metals such as nickel, cobalt, copper, and manganese, which are essential for the development of new energy technologies, electronic products, and high-tech industries. As traditional terrestrial mineral resources are increasingly depleted and environmental pressures increase, their importance has become increasingly prominent. The mining of seabed nodules is a highly complex and forward-looking mineral engineering technology that combines cutting-edge marine engineering technology with strict requirements for water ecological environment protection. Therefore, its mining faces unprecedented technical challenges and the dual test of environmental protection.

[0003] Traditional land-based mining activities face problems such as environmental damage and resource depletion, while seabed mining, as an emerging way of obtaining resources, provides the possibility of reducing the impact on land ecology. However, seabed mining technology still faces huge challenges, including high pressure, low temperature, dark deep-sea environment, complex seabed topography, and how to efficiently and environmentally friendly collect and transport seabed nodules. Current seabed mining equipment is large in size, technically complex, and has huge R&D, manufacturing, maintenance and operating costs. Minerals collected from the seabed require effective on-site processing technology and safe and efficient transportation to land. This process is complex and technically demanding; and traditional technology may have limitations in terms of precise control of mining equipment, remote operation, and efficient separation of seabed minerals, which limits mining efficiency and scope of operations.

[0004] Marine engineering plays a core role in the mining of seabed nodules, involving deep-sea platform design, submersible technology, and the construction of submarine pipelines and transportation systems. This requires innovative floating structures, fixed or mobile mining bases, and efficient underwater construction and maintenance technologies. At the same time, it is necessary to solve deep-sea communications, navigation, and energy supply problems to ensure the stability and safety of remote operations. Once a traditional mining device fails in a deep-sea environment, it is extremely difficult and expensive to maintain or rescue it. There is a lack of effective response mechanisms for device failures. In addition, due to the complex and changeable seabed topography, traditional devices are not flexible enough and cannot quickly adapt to different seabed environments and changes in mineral distribution.

[0005] The potential environmental impact of seabed mining cannot be ignored. The seabed ecosystem is fragile, and traditional mining methods may cause serious damage to the seabed ecosystem, such as stirring up sediments, affecting water quality, destroying biological habitats, and posing a threat to marine biodiversity. It has seriously damaged the marine ecological environment. At the same time, the operation of deep-sea mining equipment usually requires a lot of energy, which not only increases operating costs, but also imposes an additional carbon emission burden on the environment. Therefore, when developing new technologies, environmental protection must be taken into account, reducing the impact on benthic organisms, adopting mining methods with low or even no environmental impact, and implementing effective waste management and ecological restoration strategies.

[0057] A lower conduit 30, the upper end of which is connected to the lower end of the middle conduit 19 by a conduit mounting assembly 33, and a wire tissue ring 31 is provided on the outer wall of the conduit mounting assembly 33;

[0058] The power transmission pipe 32 is arranged on the inner wall of the lower conduit 30, the upper end of which is connected to the opening of the side wall of the conduit mounting assembly 33, and the internal circuit of which is connected to the battery;

[0061] The bottom suction cup 35 is installed on the bottom end of the motor operation compartment 34 .

[0062] When using the present invention, the system is located on the operating marine platform before startup. The staff fits the ore transport pipe into the rounded opening of the upper conduit 13, and fixes it using the inclination angle of the polygonal bracket 2 and the drag reduction sleeve 1, and then starts the device on the water surface; the system uses the differential rotation of the bidirectional power propeller 14 in the power propeller flow channel 15 to adjust the orientation of the device and move it to the designated operating area. After arriving at the target sea area, the system uses the bottom suction cup 35 below to fix the device on the operating site, and then uses the battery to power the motor 38 to drive the propeller 37 to grind the nodules in the operating area. After that, the suction of the marine platform transmits the seabed nodules through the conduits (lower conduit 30, middle conduit 19 and upper conduit 13) into the ore transport pipe and transports them to the designated area of ​​the marine platform; during the operation of the device, due to the influence of the marine environment such as waves, the system is easy to deviate from the operation, so the system is designed with a middle buffer balance structure, the joint ball (double-hole joint ball 23, three-hole joint ball 24) and the hinge (upper single ball hinge 21, lower single ball hinge 29, double ball hinge 22) are offset to one side under the action of external force, and the hinge support (upper hinge support 20, lower hinge support 2 8) The reaction springs (upper reaction spring 43 and lower reaction spring 47) on both sides of the force will generate a force in the opposite direction acting on the hinges (upper single ball hinge 21 and lower single ball hinge 29).

After the operation of the device is completed, the bidirectional power propeller 14 is started to change the movement direction of the device, and the device is separated from the working area and returns.

[0063] Compared with the prior art, the present invention has the following beneficial effects:

[0064] 1. The differential speed of the bidirectional power propeller fixedly installed in the power propeller flow channel is used to rotate the blades on the same side of the bidirectional power propeller, thereby changing the water flow discharge direction of multiple power propeller flow channels to control the movement direction of the entire device.

[0065] 2. Use the bearing and the perforated ball in the embedded track to rotate together to prevent the recovery rope from being entangled during the operation and recovery process of the device.

[0066] 3. Use the bottom suction cup to fix the device on the working area to separate the working environment from the external environment and prevent pollution of the water environment during the operation.

[0067] 4. By utilizing the interaction and coordination between the components of the middle buffer balance structure, the device is always fixed on the working area when subjected to external environmental forces, preventing the upper components of the device (control platform, upper floating structure, middle buffer balance structure, transmission structure) from dragging the bottom suction cup, thereby preventing pollution of the water environment during operation.

[0068] 5. Use a polygonal bracket to tilt at a certain angle toward the center of the rounded opening of the upper conduit, so that the ore transport pipe is firmly installed at the rounded opening of the upper conduit to prevent the ore transport pipe from detaching.

[0069] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

The interaction of the hinge in the joint ball and the reverse pulling of the reverse chain (25) on the double-hole joint ball (23) will make the device only slightly deviate even under the action of external force. At the same time, the fixing spring (27) fixes the middle guide tube (19) so that the entire device is fixed in the working area and will not deviate significantly so as to cause it to leave the working area. After the device operation is completed, the bidirectional power propeller (14) is started to change the movement direction of the device, so that the device leaves the working area and returns.
