Description

Technical Field

[0001] The present invention relates to a pump, in particular to a lifting pump for deep sea mining.

[0002] The present invention relates to a pipeline system, in particular to a pipeline system for deep sea mining. Background Art

[0003] At present, with the continuous development of mining technology, the frequency of mining of ore resources has increased significantly, and the global land ore resources are becoming increasingly scarce. In order to solve this problem, countries have turned their attention to the rich and unexploited ore resources in the ocean. In this regard, how to efficiently collect deep-sea ores has become a key research target for countries around the world. Among them, polymetallic nodules are the main collection objects at present. They are mainly located in the surface soil of the seabed at 4000-6000m. Due to the harsh deep-sea environment, mining is very difficult. Among all the known mining methods, most of them adopt the pipeline lifting method, which has the advantages of continuous work, large output, and little impact on the seabed ecosystem. The existing pipeline lifting system is mainly composed of a mining vehicle, a relay warehouse, a lifting hard pipe, a lifting pump and a mining ship. The mining principle is as follows: the mining vehicle works on the seabed, transports the collected manganese nodules to the relay warehouse through a hose, quantitatively feeds the manganese nodules into the lifting hard pipe through a feeder, and lifts the manganese nodules to the mining ship by a lifting pump. Among them, the lifting pump is an important equipment in the pipeline lifting mining system, which has high head, low flow, and coarse-grained ore flow and reflux capabilities.

[0004] At present, most pipeline lifting systems use multi-stage lifting electric pumps, which are centrifugal pumps. The pump shaft is connected to the motor shaft through a coupling, and the motor drives the centrifugal pump to rotate, thereby generating centrifugal force to lift the ore to the water surface. The advantages of this multi-stage pump are large head and large flow, but the structure is complex, the maintenance cost is high, the noise is high, and the energy loss is large due to friction. For this reason, the present invention uses a shaftless pump to replace the multi-stage centrifugal pump as a lifting device.

[0005] The Chinese patent application date is January 18, 2024, and the application number is CN202410074183.5, which discloses an independent integrated shaftless pump push and discharge device. In the disclosed technical solution, the shaftless pump includes a housing, a stator ring arranged inside the housing, a rotor assembly, and a spiral portion providing a conveying direction. However, this type of shaftless pump cannot adjust the speed during operation, and thus cannot adapt to the changing environment of the seabed. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a lift pump for deep-sea mining that can adjust the rotation speed of a mover ring.

[0007] The present invention discloses a lifting pump for deep-sea mining, comprising a shaftless pump, the shaftless pump comprising a housing, a stator ring and a mover ring installed in the housing, the stator ring and the mover ring are both circular ring structures with a central opening, the mover ring is installed at the central opening of the stator ring and is concentrically arranged, and a blade is fixed on the inner side of the mover ring; the stator ring comprises a coil arranged along the circumference of the stator ring, and the coil is connected to a circuit control board through a circuit; a plurality of magnetic strips are evenly arranged on the outer peripheral wall of the mover ring, the magnetic strips on the mover ring are driven by the magnetic force of the stator ring coil periodically input with pulse current, a gap is provided between the magnetic strips and each coil, and a distance adjustment mechanism for controlling the coil to approach or move away from the magnetic strip position is provided at the coil, and the distance adjustment mechanism comprises: A mounting seat is suspended above the magnetic strip and fixed to the coil. A screw is fixed to the portion of the mounting seat facing away from the mover ring. The screw is on the extension line of the line connecting the coil and the magnetic strip. A screw sleeve is sleeved on the screw to match the thread. A driven gear coaxially arranged with the screw sleeve is fixed to the screw sleeve. A limiting unit for limiting the mounting seat to linearly approach or move away from the magnetic strip is provided in the housing. A support platform is located above the mounting seat and fixed to the housing, the support platform is provided with a through hole for the screw sleeve to pass through, the screw sleeve and the support platform form a circumferential rotation and axial relative static fit, and the driven gear is located above the support platform; An adjusting ring rotatably mounted in the housing and arranged concentrically with the stator ring, the adjusting ring being a circular ring structure with a central opening, the adjusting ring being arranged close to the driven gear, and a side tooth is arranged on the side of the adjusting ring facing the driven gear, the side tooth meshing with the gear teeth of each driven gear; A driving motor is fixedly mounted on the housing, and a driving gear is mounted on the output shaft of the driving motor. The driving gear is located at the side teeth of the adjusting ring and meshes with the side teeth. The driving motor is controlled by the circuit control board through the circuit.

[0008] The beneficial effect of the invention is: by controlling the rotation of the active gear on the driving motor, the meshing side teeth and the adjusting ring are driven to rotate, and when the adjusting ring rotates, the driven gear will be driven to rotate, and after the driven gear rotates through the fixed screw sleeve, the mounting seat cannot rotate under the action of the limit unit and can only approach or move away from the magnetic strip in a straight line, thus driving the mounting seat fixed to the screw to move forward and backward. Under the premise of a fixed input current, the magnetic force generated by the coil on the mounting seat is constant. When the mounting seat is close to the coil, the magnetic force on the magnetic strip will increase; conversely, when it is away from the coil, the magnetic force on the magnetic strip will decrease. The present invention can control the operation of the driving motor through the circuit control board, and then control the distance between the coil and the magnetic strip, thereby changing the rotation speed of the mover ring, changing the suction force of the lifting pump, and meeting the working needs in different scenarios.

[0009] Furthermore, the limiting unit is two limiting plates fixed to the lower end of the support platform, the two limiting plates are close to the two symmetrical end surfaces of the mounting seat, and are used to limit the rotation of the mounting seat. The limiting unit uses the limiting plate to limit the rotation of the mounting seat, so that it can only move in a straight line under the rotation drive of the screw sleeve. The limiting plate has a simple structure, occupies a small space, and reduces the overall weight.

[0010] Furthermore, the surface of the adjusting ring facing the driven gear is the front side, and the surface facing away from the driven gear is the back side. A stopper is fixed on the support platform and is located on the back side of the adjusting ring and is used to prevent the adjusting ring from being separated from the contact with the driven gear. The stopper can make the adjusting ring and the driven gear contact better, and avoid the position of the adjusting ring from being offset.

[0011] Furthermore, the stator ring is provided with an annular groove arranged along the circumference of the stator ring and having the same center as the stator ring, the inner wall of the annular groove close to the mounting seat is the support platform, the adjustment ring and the driven gear are located in the annular groove, the back of the adjustment ring is in conflict with the inner wall of the annular groove, and the inner wall of the annular groove in conflict with the back of the adjustment ring is a limit stopper. The adjustment ring can be better installed on the support platform to achieve a wrapping effect, avoid deviation as much as possible, and prevent the working stability and accuracy from being affected.

[0012] Furthermore, the force-bearing surface, or the force-bearing surface and the back of the blade are provided with a plurality of grooves, which are long strips and arc-shaped with the center of the rotor ring as the center of the circle, and a plurality of protrusions are provided between two adjacent grooves. A plurality of protrusions are provided between two adjacent grooves. Based on the knowledge of bionics, the concave and convex structure of the back of desert scorpions is referred to so that they have the ability to resist wind and sand erosion. This concave and convex structure is applied to the blade structure, which can alleviate the wear and erosion of the blades caused by the impact of particles and seawater to a certain extent. In order to overcome the deficiencies of the prior art, the present invention provides a pipeline system for deep-sea mining with adjustable suction.

[0013] The present invention discloses a pipeline system for deep-sea mining, including a collection pipe and a lifting pump group installed on the collection pipe, the lifting pump group includes at least one lifting pump, the lifting pump adopts the aforementioned lifting pump, and the collection pipe connected to the lifting pump is divided into two sections, one section is connected to the inlet of the lifting pump and is sealed, and the other section is connected to the outlet of the lifting pump and is sealed.

[0014] The beneficial effect of the invention is: by controlling the rotation of the active gear on the driving motor, the meshing side teeth and the adjusting ring are driven to rotate, and when the adjusting ring rotates, the driven gear will be driven to rotate, and after the driven gear rotates through the fixed screw sleeve, the mounting seat cannot rotate under the action of the limit unit and can only approach or move away from the magnetic strip in a straight line, so the mounting seat fixed to the screw rod is driven to move forward and backward. Under the premise of fixed input current, the magnetic force generated by the coil on the mounting seat is constant. When the mounting seat is close to the coil, the magnetic force on the magnetic strip will increase; conversely, when it is away from the coil, the magnetic force on the magnetic strip will decrease. The present invention can control the operation of the driving motor through the circuit control board, and then control the distance between the coil and the magnetic strip, thereby changing the speed of rotation of the movable ring, changing the suction of the lifting pump, and realizing the working needs in different scenarios. Among them, the number of lifting pumps in each lifting pump group can be a plurality of combinations, which can improve the overall working efficiency.

[0015] Furthermore, the pipeline system also includes a pipeline stabilizing device installed on the collection pipe, the pipeline stabilizing device includes a stabilizing shell with a cavity inside, a propulsion pump is installed in the local space inside the stabilizing shell, a plurality of water inlets connected to the propulsion pump inlet through pipelines are provided at the lower part of the stabilizing shell, a plurality of water outlets connected to the propulsion pump outlet through pipelines are provided in the middle part of the stabilizing shell, the opening direction of each water outlet is horizontally arranged and located on the same plane, each water outlet is evenly arranged along the circumference of the stabilizing shell, and a control valve for controlling the opening and closing of the water outlet is provided at the water outlet; a shell inlet and a shell outlet are respectively opened at the bottom and top of the stabilizing shell, and the collection pipe connected to the stabilizing shell is divided into two sections, one section is connected to the shell inlet and sealed, and the other section is connected to the shell outlet and sealed; the propulsion pump and the control valve are both controlled by the circuit control board through the circuit. Since the collection pipe will be offset in the seawater due to the water flow, the pipeline stabilizing device sucks in the external seawater through the propulsion pump, and then sprays water out of the shell outlet in the corresponding direction through the control valve, thereby realizing that the collection pipe connected to the pipeline stabilizing device returns to the original stable position, maintaining the stability and efficiency of the lifting pump on the collection pipe when working.

The front of the adjusting ring 47 is meshed with the driven gear 44, and the back of the adjusting ring 47 is in conflict with the inner wall of the annular groove 11 and thus forms a support. The inner wall in the annular groove 11 that is in conflict with the back of the adjusting ring 47 is a limit stopper, which is used to prevent the adjusting ring 47 from retreating to the back. The radius of the annular groove 11 is adapted to the radius of the adjusting ring 47, so as to ensure that when the adjusting ring 47 is installed in the annular groove 11, the bottom of the annular groove 11 just forms a support with the bottom of the adjusting ring 47, so that the bottom of the adjusting ring 47 forms a sliding fit with the bottom of the annular groove 11.
