Description

Technical Field

[0001] The invention relates to the field of marine engineering, and in particular to an adjustable relay chamber device for a deep-sea mining hydraulic lifting system. Background Art

[0002] As the land reserves of rare metals used for high-tech development are gradually depleting, the deep sea bottom is rich in mineral resources, such as polymetallic nodules, cobalt-rich crusts, polymetallic sulfides and rare earth-rich sediments, which are generally considered to be the main rare metal resources in the future industrial intelligence era. Due to the huge reserves and wide distribution, polymetallic nodules have attracted great attention. Deep-sea mining has proven to be an efficient solution to the land resource crisis. Among them, the hydraulic lifting system, as an effective material transportation technology, shows its unique advantages. In the deep-sea mining process, the hydraulic lifting system drives the flow of seawater through a centrifugal pump, and then transports deep-sea mineral particle resources from the seabed to the surface through the flow of seawater. It is not only efficient and low-cost, but also has relatively little impact on the environment. However, the environment at sea is sometimes harsh. If an emergency occurs and the lifting system stops working, the mineral particles lifted up in the pipeline will fall back, and a large number of mineral particles will accumulate in the relay chamber and cause blockage, and the seawater cannot be discharged normally. If the lifting system is started again in this case, it is very likely to cause damage to the mining system, making the maintenance cost of deep-sea equipment huge. Summary of the invention

[0005] Furthermore, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet is lower than the output rate of mineral particles at the transport outlet, the mineral particles are not accumulated on the load-bearing platform, or the mineral particles are accumulated on the load-bearing platform but the load-bearing platform does not overcome the elastic force of the load-bearing spring and move downward; in this state, under the action of the load-bearing spring, the load-bearing platform is in a first state of sealing with the first limit ring.

[0006] Furthermore, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet is greater than the output rate of mineral particles at the transport outlet, the mineral particles accumulate on the load-bearing platform and the load-bearing platform moves downward to overcome the elastic force of the load-bearing spring; in the second state before the load-bearing platform descends to the first water inlet and outlet, the downward movement of the load-bearing platform expands the relay chamber, increasing the storage capacity of the relay chamber for mineral particles.

[0007] Furthermore, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet is greater than the output rate of mineral particles at the transport outlet, the mineral particles accumulate on the load-bearing platform and cause the load-bearing platform to move downward against the elastic force of the load-bearing spring; in the third state in which the load-bearing platform descends to the first water inlet and outlet, the first water inlet and outlet are connected to the relay chamber, and the amount of water entering the relay chamber from the first water inlet and outlet increases as the load-bearing platform descends, thereby reducing the input rate of mineral particles at the transport inlet; the mineral particles accumulated on the load-bearing platform are preferentially output from the transport outlet under the auxiliary lifting effect of the water entering the relay chamber from the first water inlet and outlet.

[0008] Furthermore, a second limiting ring is provided on the inner wall of the warehouse body below the first water inlet and outlet and close to the bottom side of the first water inlet and outlet; the load-bearing platform has the freedom to move up and down along the inner wall of the warehouse body between the first limiting ring and the second limiting ring; and a sensor is also provided on the top side of the second limiting ring.

[0009] Furthermore, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet is greater than the output rate of mineral particles at the transport outlet, the mineral particles accumulate on the load-bearing platform and cause the load-bearing platform to move downward against the elastic force of the load-bearing spring; in the fourth state when the load-bearing platform descends to the second limit ring, the sensor is triggered, and the mining vehicle coordinated with the adjustable relay bin device stops mining; the mineral particles accumulated on the load-bearing platform are preferentially output from the transport outlet under the auxiliary lifting action of the water entering the relay chamber from the first water inlet and outlet; when the accumulated mineral particles on the load-bearing platform are reduced, the load-bearing platform rises to disengage from the second limit ring under the action of the load-bearing spring, the sensor is no longer triggered, and the mining vehicle coordinated with the adjustable relay bin device continues mining.

[0010] Furthermore, a mesh screen is provided at the first water inlet and outlet to prevent mineral particles from flowing out of the relay cavity through the first water inlet and outlet.

[0011] Furthermore, the warehouse body is also provided with a second water inlet and outlet below the second limiting ring.

[0012] Furthermore, the peripheral side of the load-bearing platform is matched with the gap of the inner wall of the warehouse body; when the load-bearing platform and the first limiting ring are stuck by the mineral particles between the load-bearing platform and the first limiting ring, the gap between the load-bearing platform and the inner wall of the warehouse body allows water to pass through, driving the mineral particles to separate from between the load-bearing platform and the first limiting ring.

[0013] Furthermore, the first limiting ring is made of elastic material, and the cross-section of the first limiting ring is triangular; when the load-bearing platform and the first limiting ring are stuck by mineral particles between the load-bearing platform and the first limiting ring, the triangular cross-section of the first limiting ring is used to cause the mineral particles to separate from between the load-bearing platform and the first limiting ring.

[0014] Advantages of the present invention: The adjustable relay chamber device for a deep-sea mining hydraulic lifting system of the present invention has a self-adjusting storage space and automatically adjusts the amount of mineral particles entering according to the accumulation of mineral particles in the storage space; the overall structure is simple, safe and effective.

[0023] In an adjustable relay chamber device for a deep-sea mining hydraulic lifting system of this embodiment, the load-bearing spring is wrapped with anti-corrosion material for protection to prevent seawater from corroding the load-bearing spring.

[0024] In an adjustable relay bin device for a deep-sea mining hydraulic lifting system of the present embodiment, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet 12 is lower than the output rate of mineral particles at the transport outlet 13, and the mineral particles are not accumulated on the load-bearing platform 2, or the mineral particles are accumulated on the load-bearing platform 2 but the load-bearing platform 2 does not overcome the elastic force of the load-bearing spring 3 and move downward; in this state, under the action of the load-bearing spring 3, the load-bearing platform 2 is in a first state of sealing with the first limit ring 4.

[0025] In an adjustable relay bin device for a deep-sea mining hydraulic lifting system of the present embodiment, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet 12 is greater than the output rate of mineral particles at the transport outlet 13, the mineral particles accumulate on the load-bearing platform 2 and cause the load-bearing platform 2 to move downward against the elastic force of the load-bearing spring 3; in the second state before the load-bearing platform 2 descends to the first water inlet and outlet 14, the downward movement of the load-bearing platform 2 expands the relay chamber 11, thereby increasing the storage capacity of the relay chamber 11 for mineral particles.

[0026] In an adjustable relay bin device for a deep-sea mining hydraulic lifting system of the present embodiment, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet 12 is greater than the output rate of mineral particles at the transport outlet 13, the mineral particles are accumulated on the load-bearing platform 2 and the load-bearing platform 2 moves downward to overcome the elastic force of the load-bearing spring 3; in the third state in which the load-bearing platform 2 descends to the first water inlet and outlet 14, the first water inlet and outlet 14 is connected to the relay chamber 11, and the amount of water entering the relay chamber 11 from the first water inlet and outlet 14 will increase as the load-bearing platform 2 descends, thereby reducing the input rate of mineral particles at the transport inlet 12; the mineral particles accumulated on the load-bearing platform 2 are preferentially output from the transport outlet 13 under the auxiliary lifting action of the water entering the relay chamber 11 from the first water inlet and outlet 14.

[0027] In an adjustable relay chamber device for a deep-sea mining hydraulic lifting system of the present embodiment, a second limiting ring 5 is further provided on the inner wall of the chamber body 1 below the first water inlet and outlet 14 and close to the bottom side of the first water inlet and outlet 14; the load-bearing platform 2 has the freedom to move up and down along the inner wall of the chamber body between the first limiting ring 4 and the second limiting ring 5; and a sensor 6 is also provided on the top side of the second limiting ring 5.

[0028] In an adjustable relay bin device for a deep-sea mining hydraulic lifting system of the present embodiment, during use of the adjustable relay bin device, the input rate of mineral particles at the transport inlet 12 is greater than the output rate of mineral particles at the transport outlet 13, the mineral particles accumulate on the load-bearing platform 2 and cause the load-bearing platform 2 to move downward against the elastic force of the load-bearing spring 3; in the fourth state when the load-bearing platform 2 descends to the second limit ring 5, the sensor 6 is triggered, and the mining vehicle coordinated with the adjustable relay bin device stops mining; the mineral particles accumulated on the load-bearing platform 2 are preferentially output from the transport outlet 13 under the auxiliary lifting action of the water entering the relay chamber 11 from the first water inlet and outlet 14; when the accumulated mineral particles on the load-bearing platform 2 are reduced, the load-bearing platform 2 rises to disengage from the second limit ring 5 under the action of the load-bearing spring 3, the sensor 6 is no longer triggered, and the mining vehicle coordinated with the adjustable relay bin device continues mining.

[0029] In the adjustable relay chamber device for a deep-sea mining hydraulic lifting system of this embodiment, a mesh screen 16 is provided at the first water inlet and outlet 14 to prevent mineral particles from flowing out of the relay chamber 11 through the first water inlet and outlet 14 .

[0030] In the adjustable relay chamber device for a deep-sea mining hydraulic lifting system of this embodiment, the chamber body 1 is located below the second limiting ring 4 and is further provided with a second water inlet and outlet 15 .

[0031] In an adjustable relay bin device for a deep-sea mining hydraulic lifting system of the present embodiment, the peripheral side of the load-bearing platform 2 is matched with the inner wall gap of the bin body 1; when the load-bearing platform 2 and the first limit ring 4 are stuck by mineral particles existing between the load-bearing platform 2 and the first limit ring 4, the gap between the load-bearing platform 2 and the inner wall of the bin body 1 allows water to pass through, driving the mineral particles to separate from between the load-bearing platform 2 and the first limit ring 4.

[0032] In an adjustable relay chamber device for a deep-sea mining hydraulic lifting system of the present embodiment, the first limit ring 4 is made of elastic material, and the cross-section of the first limit ring 4 is triangular; when the load-bearing platform 2 and the first limit ring 4 are stuck by mineral particles between the load-bearing platform 2 and the first limit ring 4, the triangular cross-section of the first limit ring 4 is used to cause the mineral particles to separate from between the load-bearing platform 2 and the first limit ring 4.

[0033] The adjustable relay chamber device of the present embodiment is used in a deep-sea mining hydraulic lifting system, wherein the transport inlet is connected to the mining vehicle via a hose; and the transport outlet is connected to the transport riser of the lifting system.

[0034] like Figure 1 As shown, in the first state, the load-bearing platform is connected to the load-bearing spring. The load-bearing spring is set with a certain compression force, so that the load-bearing platform presses against the first limit ring to achieve the sealing of the relay cavity, preventing seawater from flowing between the load-bearing platform and the relay cavity, so that the mineral particles and seawater transported from the mining vehicle to the relay cavity through the hose can be smoothly pumped out through the transport riser, and the transport riser is not allowed to directly transport seawater below the load-bearing platform; when the lifting system is working normally, the mineral particles entering the relay cavity from the transport inlet will continue to enter the transport riser through the transport outlet along with the water flow, and finally reach the offshore working platform;

[0035] like Figure 2 As shown, in the second state, when the mining vehicle has a high collection efficiency, the rate of mineral particles entering the relay chamber from the transport inlet is greater than the rate of mineral particles flowing out through the transport outlet, and the mineral particles will accumulate on the load-bearing platform of the relay chamber. When the weight of the accumulated mineral particles reaches a certain level, the load-bearing spring will be compressed and dropped, and the space available for placing mineral particles in the relay chamber will become larger.

[0036] When the load-bearing platform moves upward to reset, there are still mineral particles that have not been lifted on the upper edge of the load-bearing platform. At this time, the reset will cause the mineral particles to be stuck between the first limit ring and the load-bearing platform, resulting in the inability to seal the relay cavity; the cross-section of the first limit ring is set to be triangular, and the material is elastic material, which can make the mineral particles move toward the center of the load-bearing platform under the squeezing of the load-bearing platform and the first limit ring; at the same time, the peripheral side of the load-bearing platform and the inner wall gap of the warehouse body are matched, and when the relay cavity is not completely sealed due to mineral particles, when the lifting system is working, water will flow from bottom to top through this gap, and it will also drive the mineral particles to move toward the middle of the load-bearing platform; at the same time, the first limit ring made of elastic material will make the sealing effect between the load-bearing platform and the first limit ring better; before the load-bearing platform descends to the first water inlet and outlet, due to the small gap between the load-bearing platform and the warehouse body, it has little effect on the flow entering the relay cavity from the transport inlet.

[0037] In the adjustable relay chamber device for a deep-sea mining hydraulic lifting system of the present embodiment, in the first state and the second state, the movable range of the load-bearing platform between the first limit ring and the first water inlet and outlet is a normal working state; within this range, the load-bearing spring and the load-bearing platform can realize self-adjustment according to the weight of the mineral particles to prevent the mineral particles in the relay chamber from being blocked.

[0038] like Figure 3 As shown, in the third state, the minerals continue to accumulate, and the bearing platform continues to descend, and the first water inlet and outlet are connected to the relay chamber. At this time, since the water level of the mining vehicle is much lower than the relay chamber, the minerals in the relay chamber will be transported out first; at this time, the water intake through the first water inlet and outlet will increase as the bearing platform descends, and the flow rate from the transport hose into the relay chamber will gradually decrease. In this process, if there is no major failure in the lifting system (such as shutdown, large-scale blockage), the first water inlet and outlet will be closed by the rebounding bearing platform as soon as it is connected to the relay chamber. This is because after the first water inlet and outlet are connected to the relay chamber, the flow rate entering the relay chamber from the transport inlet will be significantly reduced, resulting in a reduction in the number of mineral particles entering the relay chamber. At the same time, the seawater flowing into the first water inlet and outlet will produce a significant upward lifting force on the mineral particles on the bearing platform, which will cause these mineral particles to quickly leave the bearing platform, and the bearing platform will rebound upward. This process will not last too long and will not have a significant impact on the collection efficiency of the mining vehicle.

[0039] In an adjustable relay chamber device for a deep-sea mining hydraulic lifting system of this embodiment, the total cross-sectional area of ​​the first water inlet and outlet is larger than the cross-sectional area of ​​the transport inlet. If too many mineral particles accumulate on the load-bearing platform, the mineral particles in the relay chamber will be transported out first.

[0040] like Figure 4As shown, in the fourth state, if a major failure occurs in the lifting system (such as shutdown, large-scale blockage), the particles on the load-bearing platform will be difficult to lift, and the continued accumulation of mineral particles will cause the load-bearing platform to be pressed to the second limit ring. At this time, the mining vehicle must stop running, otherwise the mining vehicle will only move forward without continuing mining, and the mining efficiency will be zero, wasting the energy consumption and movement stroke of the mining vehicle; at this time, the sensor located on the second limit platform (a pressure sensor can be used) will immediately sense and send a remote instruction through the computer to stop the movement and collection of the mining vehicle to avoid wasting the mining path. The lifting system preferentially transports the mineral particles accumulated in the relay bin to the offshore platform through the transport riser. After the accumulated mineral particles are sucked out through the transport riser, the load-bearing spring will gradually move upward under the action of the load-bearing spring as the accumulated mineral particles decrease, until it is reset to the first state, that is, sealed with the first limit ring.

[0041] The adjustable relay bin device for a deep-sea mining hydraulic lifting system of the present embodiment, when the lifting system stops working due to the offshore environment, the mineral particles in the transport riser that fail to reach the offshore working platform will fall back to the relay chamber and accumulate on the load-bearing platform. When the weight of the mineral particles reaches a certain range, the load-bearing spring will be compressed, and the space available for placing the mineral particles in the relay bin device will become larger. When the load-bearing platform descends to reach the second limit ring, the maximum weight of the mineral particles that can be carried is reached at this time. The water in the relay bin device can be discharged through the first water inlet and outlet and the second water inlet and outlet. The mesh screen installed at the first water inlet and outlet can prevent the mineral particles from flowing out of the relay chamber. When restarting, the mineral particles that flow back in the relay bin and the transport riser can be lifted preferentially; when the accumulated mineral particles are discharged through the transport outlet, under the action of the load-bearing spring, the load-bearing platform gradually moves upward until it is reset to the first state, that is, sealed with the first limit ring.

[0042] The adjustable relay chamber device for a deep-sea mining hydraulic lifting system of the present embodiment can, during the mining process, when the input rate of mineral particles entering the relay chamber through the transport inlet is greater than the output rate of mineral particles flowing out of the relay chamber through the transport outlet, the mineral particles will accumulate on the load-bearing platform. At this time, the relay chamber can self-regulate to increase the space for storing minerals in the relay chamber and reduce the amount of mineral particles entering the relay chamber through the transport inlet, so that the lifting system gives priority to lifting the minerals accumulated in the relay chamber; and when the storage volume in the relay chamber reaches the peak value, the mining vehicle is shut down in time to avoid wasting the mining path; when the work is stopped due to an emergency, more minerals that fall back can be stored to prevent blockage and damage to the mining system and the lifting system; when restarting, the minerals returning in the relay chamber and the transport riser can be lifted preferentially.

[0043] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion shall fall within the protection scope of the present invention.
