Embodiment

[0024] Such as figure 1 As shown, the deep-sea mineral full-hose transportation offshore test system of this embodiment includes a water surface operation platform 1, a flexible circulation pipe 2 and circulation equipment 3. Both ends of the flexible circulation pipe 2 are fixed on the water surface operation platform 1, and the middle part is set At the underwater collection depth to be tested, the flexible circulation pipe 2 is also provided with monitoring equipment for monitoring the state of the flexible circulation pipe 2 to monitor the state of the flexible circulation pipe 2 during deep sea mining and transportation. The test system of this embodiment fills the blank of hose transportation in deep sea mining, provides test equipment and foundation for the later use of hose transportation instead of hard pipe transportation, and speeds up the process of light and convenient deep sea mining systems.

[0025] In addition, during the test process, the test system is in th...

Abstract

The invention discloses a deep sea mineral product full-hose conveying offshore test system which comprises a water surface operation platform, a flexible circulating pipe and circulating equipment, and is characterized in that the two ends of the flexible circulating pipe are fixed on the water surface operation platform, and the middle part of the flexible circulating pipe is arranged at an underwater collection depth to be tested; the flexible circulating pipe is further provided with monitoring equipment used for monitoring the state of the flexible circulating pipe, and the flexible circulating pipe is driven by the circulating equipment to lift a solid-liquid mixture at the underwater collection depth to be tested to one end located on the water surface operation platform. Then the solid-liquid mixture is conveyed to the other end of the flexible circulating pipe through circulating equipment and reaches the underwater collection depth to be tested through the flexible circulating pipe. The deep sea mineral product full-hose conveying offshore test system has the advantages of being simple in structure, easy and convenient to operate, real in test environment, reliable in test data, capable of being arranged for hose conveying and the like.

Description

technical field [0001] The invention relates to the technical field of deep-sea mining equipment testing, in particular to an offshore test system for full-hose transportation of deep-sea minerals. Background technique [0002] Metal mineral resources in the deep sea area include polymetallic nodules, polymetallic sulphides, and cobalt-rich crusts. These resources are all stored in thousands of meters of deep-seabed deposits. It is generally believed that the resource collection mode of mining vehicle mining-hydraulic lifting pipeline transportation-sea surface engineering ship has the most commercial value. At present, there are also experimental methods for hydraulic lift pipeline transportation through theoretical calculation, simulation analysis, and laboratory test research. However, these studies are all simulated or hypothetical working conditions. Due to the limitation of the test space, the length of the riser is generally only a few dozen. Meter high, it is very d...
