Problems solved by technology
When the topography of the seabed changes and the shear strength of the sediment changes greatly, the mechanism cannot maintain the height of the suction inlet of the follow-up collection channel well, and there are deficiencies such as low collection efficiency and more sediment inhalation; the delivery nozzle is located at the collection The upper part of the conveying channel causes the lower part of the collection and conveying channel to form a low-velocity zone, causing larger nodules to accumulate at the collection suction port, causing blockage or inability to transport efficiently

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0025] Such as figure 1 with figure 2 As shown, the hydraulic collection mechanism of the present invention includes a seabed mining vehicle 1, a collection and transportation pipeline 2 and a separation device 3. The front end of the collection and transportation pipeline 2 is provided with a suction port 20, which is in the shape of a bell mouth, which is conducive to the collection of minerals. . The separation device 3 is connected to the rear-end output port of the collection and conveying pipe 2. Both the front and back sides of the suction port 20 are provided with disturbing nozzles 4. The terrain adaptive compensation device is installed on the seabed mining vehicle 1, which can float up and down relative to the seabed mining vehicle 1. The collection and transportation pipeline 2 is also provided with a sliding plate 6 supporting it on the...

The invention discloses a hydraulic collection mechanism, which comprises a seabed mining vehicle, a collection and transportation pipeline and a separation device. The front end of the collection and transportation pipeline is provided with a suction port, and the separation device is connected with the rear end output port of the collection and transportation pipeline. Disturbance nozzles are provided on both sides. The collection and delivery pipeline is equipped with delivery nozzles for spraying and delivering water flow. The collection and delivery pipeline is installed on the seabed mining vehicle by floating up and down through the terrain adaptive compensation device. It is supported by a sliding plate on the surface of the seabed sediment, and the sliding plate is located below the suction inlet and has a vertical distance from the suction inlet. The invention has the advantages of high collection efficiency, stable and reliable operation, little environmental disturbance, self-adaptation to seabed terrain environment and geological environment, and the like.
Description
Technical field [0001] The invention relates to the technical field of subsea engineering operation equipment, in particular to a hydraulic collection mechanism suitable for combined collection of multiple metals on the seabed. Background technique [0002] Manganese nodules mainly occur in the surface layer of seabed sediments with a water depth of 3000-6000m and low carrying capacity and shear strength. The thickness of the sediments can reach hundreds of meters or even hundreds of meters. According to preliminary survey estimates, the total reserves are about 3 trillion tons, of which there are about 70 billion tons worth of industrial mining reserves, and the annual growth rate is about 10 million tons. The mining of deep-sea manganese nodules is a high-tech intensive field. Its mining system is a huge and complex system engineering. Mining and ore lifting are the core technology and key components of the mining system. [0003] Hydraulic collection institutions are considered...
