[0041] The deep sea is rich in mineral resources, including polymetallic nodules, polymetallic sulfides, and cobalt-rich crusts, boasting extremely high resource abundance and economic value. Rich in metals like manganese, nickel, and copper, polymetallic nodules are widely used in smelting, metallurgy, aviation, aerospace, and other related industries. Their vast reserves and widespread distribution offer significant development potential, making their mining technology a hot topic for experts and scholars worldwide in recent years.

[0042] Extensive research has shown that pipeline-lift collection systems, with their advantages of simple structure, good operational continuity, and high economic efficiency, are the current mainstream collection system. As the primary component of a pipeline-lift collection system, the collection efficiency of the collection device directly impacts the overall performance of the collection system. Collection devices can be further categorized into mechanical, hydraulic, and mechanical-hydraulic combined types, depending on the collection method. Existing collection devices are mostly hydraulic, using jet methods such as wall-coated jets and double-row jets to scour nodules, breaking them up and facilitating their absorption by the collection device. However, current collection devices generally suffer from high energy consumption and significant environmental disturbance, making it difficult to balance economic efficiency, collection efficiency, and environmental protection.

[0043] In this regard, the present application proposes a rotary bucket hydraulic ore collecting device and a working method thereof, wherein seabed minerals are crushed by a jet nozzle 300, and the crushed minerals are excavated and collected by a bucket 210, wherein the crushing and collection of the minerals are completed in the shell 100. On the one hand, it can reduce the impact on the external environment, and on the other hand, the kinetic energy of the jet is preserved by the shell 100, thereby fully improving the efficiency of the jet crushing; a plurality of jet nozzles 300 are provided, and the corresponding jet nozzle 300 will only be opened when the bucket 210 is excavating, thereby reducing energy consumption and making full use of the jet kinetic energy.

[0044] Reference Figure 1 and Figure 2The rotary bucket hydraulic ore collection device in the embodiment of the first aspect of the present application includes a housing 100, an excavating element 200, a jet nozzle 300, a flow guide 400, and a jet assembly 500. The housing 100 is used to form a semi-enclosed excavation space, allowing the minerals crushed by the jet to be concentrated in the excavation space for excavation. The excavating element 200 is used to excavate the minerals. The jet nozzle 300 is used to emit a jet to crush the minerals. The flow guide 400 is used to guide the jet from the jet assembly 500 to the jet nozzle 300 and to transport the minerals excavated by the excavating element 200 to the jet assembly 500.

[0045] Specifically, the bottom of the housing 100 is open to facilitate digging of the seabed by the digging member 200. A supporting structure 110 is installed on the outside of the housing 100, which is provided with mounting holes for connecting to external equipment, thereby fixing the housing to the external equipment through the supporting structure 110.

[0046] The excavation element 200 rotates within the housing 100 and specifically comprises interconnected buckets 210 and a conduit 220. There are at least two buckets 210 arranged in a circular array around the conduit 220. In this embodiment, there are four buckets 210. Conduit 220 contains chambers connected to each bucket 210. As the excavation element 200 rotates, the buckets 210 excavate the seabed and scoop up minerals. As the buckets 210 continue to rise, the minerals roll down due to gravity into the chambers of conduit 220, awaiting subsequent transport.

[0047] Furthermore, barriers are provided on both sides of the bucket 210 to prevent the minerals from sliding off the sides of the bucket 210 .

[0048] The jet nozzle 300 is mounted on the back of the bucket 210 and faces another adjacent bucket 210. Thus, the jet nozzle 300 can apply a force toward the bucket 210 to the mineral while spraying the jet to break the seabed, making it easier for the mineral to enter the bucket 210.

[0049] The flow guide 400 is mounted on one side of the excavating element 200 and rotates with it. The flow guide 400 includes an outlet portion 410 and an inlet portion 420, which are interconnected. An outlet port 411 is provided in the center of the outlet portion 410, communicating with the chamber of the confluence portion 220. This allows minerals within the chamber of the confluence portion 220 to be transported outward through the outlet port 411. There are at least two inlet portions 420, which are arranged in a circular array around the outlet portion 410, with each inlet portion 420 corresponding to each bucket 210. The inlet portion 420 has an inlet port 421 and a channel disposed within the inlet portion 420 that communicates with the inlet port 421 and connects to the jet nozzle 300. Notably, the inlet port 421 is arc-shaped, with its center located on the central axis of the flow guide 400.

[0050] The jet assembly 500 includes an inlet pipe 510 and an outlet pipe 520. The outlet pipe 520 is connected to the outlet port 411 of the guide member 400 to absorb minerals. Figure 3 The orifice of the injection tube 510 corresponds to the injection port 421 of the guide member 400. When the guide member 400 rotates with the excavating member 200 and the injection port 421 rotates to the orifice of the injection tube 510, the injection tube 510 communicates with the channel inside the injection portion 420. The jet can then flow through the channel to the jet nozzle 300 to complete the injection operation. When the guide member 400 continues to rotate, causing the orifice of the injection tube 510 to contact the surface of the guide member 400, the jet is not connected. It waits for the next injection port 421 to rotate to the orifice of the injection tube 510 to reconnect. Thus, the injection tube 510 triggers each jet nozzle 300 in turn, reducing jet waste.

[0051] When the inlet port 421 of the flow guide 400 rotates to the outlet of the inlet pipe 510, the jet in the inlet pipe 510 flows into the channel and is ejected from the jet nozzle 300, impacting and crushing the seabed to facilitate scooping by the bucket 210. The bucket 210 rotates, causing the crushed minerals to slide into the confluence portion 220, where they are collected through the outlet port 411 and the outlet pipe 520 and then to an external mineral collection device.

[0052] Furthermore, the rotary bucket hydraulic ore collecting device also includes a hydraulic rod 600, the jet nozzle 300 is hinged to the bucket 210, and the two ends of the hydraulic rod 600 are respectively hinged to the jet nozzle 300 and the bucket 210. The hydraulic rod 600 is used to change the ejection angle of the jet nozzle 300 so that the jet ejected by the jet nozzle 300 continuously hits the seabed, thereby improving the mineral crushing efficiency.

[0053] For the length control of the hydraulic rod 600, refer to Figure 4 Assume that the initial length of hydraulic rod 600 is L0, the vertical distance between hydraulic rod 600 and bucket 210 at jet nozzle 300 is D, and the vertical distance between hydraulic rod 600 and jet nozzle 300 at bucket 210 is 4D. When bucket 210 approaches the seabed surface, jet nozzle 300 begins to spray water, corresponding to an angle θ between jet nozzle 300 and the horizontal. The length of hydraulic rod 600, L0, can be expressed using the sine theorem as:

[0054]

[0055] Assuming that the rotational angular velocity of the excavating member 200 is ω, after a time period Δt, the angle Δθ through which the excavating member 200 rotates is:

[0056] Δθ=ω·Δt

[0057] To maintain the angular stability of the jet nozzle 300, the angle needs to be corrected by changing the length of the hydraulic rod 600. After a period of time Δt, the jet nozzle 300 needs to rotate through an angle Δθ to maintain the original angle. Assuming the length change of the hydraulic rod 600 is ΔL, the length of the hydraulic rod at this time can be expressed as:

[0058] (L0+ΔL) 2 =D 2 +(4D) 2 +2·D·(4D)·sin(90+θ-Δθ)

[0059] =D 2 +(4D) 2 +2·D·(4D)·sin(90+θ-ω.Δt)

[0060] By differentiating both sides of the above equation with respect to time Δt, the speed control equation of the hydraulic rod 600 can be obtained.

[0061] Assuming that the lower end of the bucket 210 is close to the seabed surface as the initial state, and the excavation component 200 rotates 360° as a working cycle, it is assumed that the initial angle θ of the jet nozzle 300 at this moment is 45° downward compared to the horizontal direction. At this time, the injection pipe 510 matches the injection port 421, and the jet nozzle 300 close to the seabed surface begins to spray water. During the process of the excavation component 200 rotating counterclockwise at an angle θ0 from 0° to 90°, the hydraulic rod 600 can ensure that the angle of the jet nozzle 300 always remains 45° downward from the horizontal direction. When θ0 reaches 90°, the length of the hydraulic rod 600 reaches the shortest. When the rotation angle θ0 is from 90° to 360°, the group of hydraulic rods 600 returns to the initial length and remains unchanged. In each rotation cycle, the length change L of a single hydraulic rod 600 can be expressed as:

[0062]

[0063] Furthermore, the height of the injection tube 510 is lower than the rotation axis of the excavating member 200 , so that when the bucket 210 at the bottom is excavating, the corresponding jet nozzle 300 sprays the seabed to drive the minerals into the bucket 210 .

[0064] Further, refer to Figure 5 The jet assembly 500 further includes a jet pump inlet pipe 530, which serves as a branch pipe connected to the outlet pipe 520. The jet pump injects a high-speed jet into the jet pump inlet pipe 530. At the connection between the jet pump inlet pipe 530 and the outlet pipe 520, the jet direction of the jet pump inlet pipe 530 forms an acute angle with the direction of fluid movement in the outlet pipe 520. As a result, the jet ejected from the jet pump inlet pipe 530 can drive the fluid in the outlet pipe 520 to move, thereby discharging the minerals in the outlet pipe 520.

[0065] Furthermore, the jet assembly 500 further includes a docking tube 540, which docks with the outlet tube 520 and the jet pump inlet tube 530 is connected to the docking tube 540. It is worth noting that the docking tube 540 is provided with a tapered tube section to guide the jet from the jet pump inlet tube 530 to merge with the fluid from the outlet tube 520.

[0066] Furthermore, the upper portion of the shell 100 is arc-shaped and adapted to the excavating piece 200, which minimizes the volume of the shell 100. After the bucket 210 scoops up the minerals, the shell 100 can prevent the minerals from falling from both sides of the bucket.

[0067] In an embodiment of the second aspect of the present application, a working method based on the rotary bucket type hydraulic ore collecting device comprises the following steps:

[0068] S100. The rotary bucket hydraulic ore collection device is brought close to the seabed through an external drive device;

[0069] S200 starts the external jet device, and the high-speed jet flows into the injection tube 510;

[0070] S300 starts the rotary bucket hydraulic ore collection device, the excavation member 200 begins to rotate;

[0071] S400. The inlet port 421 of the guide member 400 rotates to the outlet of the injection tube 510, and the high-speed jet flows through the channel of the guide member 400 to the jet nozzle 300, and the jet ejected by the jet nozzle 300 crushes the seabed minerals;

[0072] S500. The excavating member 200 continues to rotate, and the bucket 210 scoops up the crushed minerals;

[0073] S600. The bucket 210 rotates to a high position, and the minerals slide to the confluence portion 220 of the excavation member 200 due to gravity;

[0074] S700. The mineral is output to the outlet pipe 520 via the outlet port 411 of the guide member 400, and the mineral enters the external mineral collection device along the outlet pipe 520;

[0075] S800. Repeat the above steps to continuously collect seabed minerals.

[0076] The above is a specific description of the preferred implementation methods of the present application, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
