Description

Technical Field

[0001] This invention relates to the field of deep-sea mining technology, and in particular to a pre-separation device for deep-sea mining operations. Background Technology

[0002] Trailing suction hopper (LSH) mining equipment has been widely used in deep-sea mineral resource extraction operations due to its outstanding advantages such as flexible operation, continuous mining capability, high degree of automation, and good adaptability to complex deep-sea conditions. It uses negative pressure suction to draw seabed minerals in and elevate them along a pipeline to a surface support platform. The entire extraction and transportation process is continuous and efficient, effectively coping with the complex conditions of the deep-sea environment, such as high pressure, low temperature, and undulating terrain. It is currently one of the mainstream mining equipment in the deep-sea mining field.

[0003] However, because trailing suction hopper mining machines rely on negative pressure suction for ore transport, a large number of large-diameter particles of varying sizes inevitably mix into the seabed-harvested ore. These large particles, carried by the fluid into the transport pipeline and deep-water pump, are highly susceptible to impact, jamming, and even blockage at pump impellers, flow channel bends, and abrupt changes in pipe diameter. This leads to accelerated pump wear, a sharp drop in transport efficiency, and even equipment shutdowns. Frequent blockages and wear not only severely restrict the continuity and stability of mining operations but also significantly increase the frequency of equipment maintenance and the cost of parts replacement.

[0004] Therefore, there is an urgent need to provide a pre-separation device for deep-sea mining operations to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a pre-separation device for deep-sea mining operations, which actively separates and temporarily stores large-diameter particles before they enter the deep-water pump, thereby preventing pump blockage and wear and ensuring the continuity and safety of deep-sea mining operations.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows: A pre-separation device for a deep-sea mining facility, comprising: A primary filter cartridge is connected to the collection head and has a primary filter chamber inside. The outer wall has multiple primary filter holes that communicate with the primary filter chamber. The primary filter holes are located on the wall surface where the primary filter cartridge is connected to the deep water pump and are used to trap large-diameter particles. The large-diameter particles are particles with a diameter greater than a set size. A separation assembly includes a housing, a rotating component, a stop plate, four stop members, and four first elastic members. The housing is connected to the bottom surface of the primary filter cartridge and has a separation chamber communicating with the primary filter chamber. The inner wall of the separation chamber is provided with a groove. The rotating component is rotatably installed in the separation chamber and divides the separation chamber into four chambers through four flow-blocking plates. The stop plate is provided in the groove and has a T-shaped hole. The bottom of the chamber opposite the groove is provided with a discharge port. One end of each of the four stop members is correspondingly hinged to the same side of the four flow-blocking plates along the rotation direction, and the other end is connected to the corresponding flow-blocking plate through the first elastic member. In the initial state, the head of one of the stop members is inserted into the groove and abuts against the narrow section of the T-shaped hole. The corresponding first elastic member is in a relaxed state, and the chamber above the corresponding baffle plate is directly connected to the primary filtration chamber. When the weight of the large-diameter particles accumulated on the baffle plate facing the primary filtration chamber exceeds the pre-tightening force of the first elastic member, rotation occurs. The corresponding stop member moves toward the wide section of the T-shaped hole and passes through the T-shaped hole. The corresponding baffle plate rotates, so that when the next stop member reaches the groove position, it rotates under the elastic force of the corresponding first elastic member and abuts against the stop plate. A collection box is located below the discharge port to receive the large-diameter particles.

[0007] Furthermore, the pre-separation device of the deep-sea mining mechanism also includes a filtration assembly, which includes a shell, a filter cylinder, a drive unit, and a stirring unit. The shell is connected to the bottom of the housing and has a filter chamber communicating with the discharge. The shell is connected to the primary filter cylinder and the deep-water pump. The filter cylinder is located in the filter chamber and has an opening on its top surface communicating with the discharge port. The filter cylinder has several filter holes on its peripheral wall for intercepting large-diameter particles and an outlet on its bottom surface. The storage box is connected to the bottom of the shell and communicates with the outlet. The drive unit is installed in the storage box. The stirring unit is connected to the output end of the drive unit and extends into the filter cylinder through the outlet.

[0008] Furthermore, the filter assembly also includes a plurality of baffles arranged at intervals in the filter cylinder along the vertical direction, and the projections of two adjacent baffles along the vertical direction do not overlap. The stirring component includes a rotating rod and a plurality of stirring rods. The rotating rod is connected to the output end of the driving component. The plurality of stirring rods are arranged at intervals in the axial direction on the rotating rod and abut against the top surface of the plurality of baffles in a corresponding manner.

[0009] Furthermore, the pre-separation device of the deep-sea mining mechanism also includes a temporary storage component, which includes a temporary storage box, a fixed plate, a rotating plate, and a second elastic element. The temporary storage box is connected to the top wall of the storage box and has an inlet on its top surface that connects to the outlet. The bottom surface of the temporary storage box has a discharge outlet. The fixed plate is connected to the inner side wall of the temporary storage box and extends obliquely to the discharge outlet. The rotating plate includes a first plate body, a shaft part, and a second plate body part connected in sequence. The rotating plate is rotatably disposed at the discharge outlet through the shaft part, and the shaft part abuts against the lower end of the fixed plate. The second elastic element connects the first plate body part and the fixed plate. In the initial state, the second elastic element is in a natural state, and the second plate body part and the fixed plate together cover the discharge outlet.

[0010] Furthermore, the temporary storage box is provided with an mounting plate, which is parallel to the fixed plate. The stirring component is rotatably inserted through the mounting plate, with one end extending into the filter cylinder and the other end connected to the output end of the driving component.

[0011] Furthermore, the deep-sea mining mechanism's pre-separation device also includes a workbench, which is mounted on the track support of the ore collecting vehicle. The outer shell and the filter cylinder are mounted on the top surface of the workbench, and the storage box is mounted on the bottom surface of the workbench.

[0012] Furthermore, the stop member includes a rod and two pulleys. One end of the rod is hinged to the corresponding flow-blocking plate, and the other end is rotatably connected to the pulleys on opposite sides along the width direction. The two pulleys can pass through the wide section of the T-shaped hole, and the rod can pass through the narrow section of the T-shaped hole.

[0013] Furthermore, the primary filtration chamber includes a first chamber and a second chamber that are connected to each other. The second chamber gradually contracts away from the first chamber and is directly connected to the separation chamber.

[0014] Furthermore, the inner wall of the first cavity is provided with a guide surface, which is inclined toward the entrance of the second cavity.

[0015] Furthermore, the first elastic element is rotatably mounted on the corresponding flow-blocking plate via a hinge support.

[0016] The beneficial effects of this invention are: The pre-separation device for deep-sea mining proposed in this invention involves the ore entering the primary filter chamber of the primary filter cylinder through the collection head. The primary filter holes, with their limited apertures, draw small-diameter particles into the deep-water pump while simultaneously trapping large-diameter particles within the primary filter chamber, preventing them from entering the downstream pipeline, thus achieving the first step of particle size classification. The trapped large-diameter particles, under the influence of gravity, fall into the chamber corresponding to the baffle plate directly opposite the primary filter chamber. As large particles continuously accumulate on the baffle plate within this chamber, the total weight increases. When this weight exceeds the preload of the corresponding first elastic element, the baffle plate compresses the stop element, causing it to rotate. Due to the stop plate's obstruction, the stop element rotates relative to the baffle plate, causing its head to move from the narrow section of the T-shaped hole to the wide section and eventually pass through. This drives the baffle plate to rotate, releasing the large-diameter particles accumulated on the baffle plate through the discharge port into the collection box below. Meanwhile, the rotating component continues to rotate under the influence of the release of large-diameter particles and the disturbance of water flow. When the next stop component reaches the groove position, it rotates under the elastic force of the corresponding first elastic component and re-aggregates against the narrow section of the T-shaped hole. This causes the corresponding baffle plate to rotate into position facing the primary filtration chamber, restoring the sealing state and completing the chamber switching. This cyclical alternation process ensures that large particles are actively separated and temporarily stored in the collection tank before entering the deep-water pump, preventing them from entering the pump body and flow channel at the source, thereby preventing blockage, wear, and equipment failure. In addition, the entire separation action does not require external control signals and relies entirely on the self-weight of the particles and the pre-tightening force of the first elastic component for adaptive triggering. Combined with the continuous alternating operation of the four chambers, this fully ensures the continuity and safety of deep-sea mining operations. Attached Figure Description

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, this invention proposes a pre-separation device for a deep-sea mining mechanism, connected in series between a collection head 100 and a deep-water pump 200. It includes a primary filter cartridge 1, a separation assembly 2, and a storage box 3. The primary filter cartridge 1 is connected to the collection head 100 and has a primary filter chamber 10 inside. Its outer wall has multiple primary filter holes 11 communicating with the primary filter chamber 10. The primary filter holes 11 are located on the wall surface connecting the primary filter cartridge 1 and the deep-water pump 200 to trap large-diameter particles, which are particles with a diameter larger than a set size. The separation assembly 2 includes a housing 21, a rotating component 22, a stop plate 23, four stop components 24, and four first elastic components 25. The housing 21 is connected to the bottom surface of the primary filter cartridge 1 and has a separation chamber 210 communicating with the primary filter chamber 10. The inner wall of the separation chamber 210 has a groove. The rotating component 22 is rotatably installed in the separation chamber 210, and the separation chamber 210 is divided into four chambers by four flow-blocking plates 221. The stop plate 23 is located in the groove and has a T-shaped hole 23. 0. A discharge port is provided at the bottom of the chamber directly opposite the groove. One end of each of the four stop members 24 is hinged to the same side of the four baffle plates 221 along the rotation direction, and the other end is connected to the corresponding baffle plate 221 through the first elastic member 25. In the initial state, the head of one of the stop members 24 is inserted into the groove and abuts against the narrow section of the T-shaped hole 230. The corresponding first elastic member 25 is in a relaxed state. The chamber above the corresponding baffle plate 221 is directly connected to the primary filter chamber 10. When the weight of the large-diameter particles accumulated on the baffle plate 221 directly opposite the primary filter chamber 10 exceeds the pre-tightening force of the first elastic member 25, it rotates. The corresponding stop member 24 moves toward the wide section of the T-shaped hole 230 and passes through the T-shaped hole 230. The corresponding baffle plate 221 rotates, so that when the next stop member 24 reaches the groove position, it rotates under the elastic force of the corresponding first elastic member 25 and abuts against the stop plate 23. The collection box 3 is set below the discharge port and is used to receive large-diameter particles.

[0025] After the ore enters the primary filter chamber 10 of the primary filter cylinder 1 through the collection head 100, the primary filter holes 11, through their diameter restriction, draw small-diameter particles into the deep water pump 200, while simultaneously trapping large-diameter particles within the primary filter chamber 10, preventing them from entering the downstream pipeline, thus achieving the first step of particle size classification. The trapped large-diameter particles, under the influence of gravity, fall into the chamber corresponding to the baffle plate 221 directly opposite the primary filter chamber 10. As large particles continuously accumulate on the baffle plate 221 within this chamber, the total weight continues to increase. When this weight exceeds the preload of the corresponding first elastic element 25, the baffle plate 221 compresses the stop element 24, causing it to rotate. Due to the obstruction of the stop plate 23, the stop element 24 rotates relative to the baffle plate 221, causing its head to move from the narrow section of the T-shaped hole 230 to the wide section of the T-shaped hole 230 and eventually pass through it. This causes the baffle plate 221 to rotate, releasing the large-diameter particles accumulated on the baffle plate 221 through the discharge port into the collection box 3 below. Meanwhile, the rotating part 22 continues to rotate under the action of large-diameter particle release and water flow disturbance, so that when the next stop part 24 reaches the groove position, it rotates under the elastic force of the corresponding first elastic part 25 and re-abuts against the narrow section of the T-shaped hole 230, thereby causing the corresponding flow baffle 221 to rotate into the position facing the primary filter chamber 10, restoring the sealing state and completing the chamber switching. This cyclical alternation process ensures that large particles are actively separated and temporarily stored in the storage box 3 before entering the deep water pump 200, preventing them from entering the pump body and flow channel from the source, thereby preventing blockage, wear and equipment failure. In addition, the entire separation action does not require external control signals, and is entirely triggered by the self-weight of the particles and the pre-tightening force of the first elastic part 25. With the continuous alternation of the four chambers, the continuity and safety of deep-sea mining operations are fully guaranteed. The diameter of the primary filter hole 11 is set according to the target mineral particle size distribution of deep-sea mining operations and the allowable particle size of the deep water pump 200, and is not specifically limited here.

[0026] It is understood that the rotating component 22 has a cross-shaped structure, and its center is rotatably connected to the inner wall of the separation cavity 210 via a rotating shaft. The separation cavity 210 is a cylindrical cavity with a groove on its inner wall. The stop plate 23 is set in the groove and does not protrude from the groove surface. It is only used to form abutment and limiting fit with the stop component 24, and will not interfere with the normal flipping of the flow baffle 221. During the rotation of the rotating component 22, the stop component 24 always abuts against the inner wall of the separation cavity 210, and its corresponding first elastic component 25 remains in a compressed state. When a stop component 24 rotates with the corresponding flow baffle 221 to the groove position, the stop component 24 loses the abutment constraint of the inner wall of the separation cavity 210, and the corresponding first elastic component 25 is released from the compressed state, pushing the stop component 24 to rotate outward, so that its head abuts against the narrow section of the T-shaped hole 230 of the stop plate 23, thereby achieving limiting and locking.

[0027] In this embodiment, the T-shaped hole 230 includes a wide section and a narrow section that are connected. The wide section faces the bottom of the groove, and the narrow section extends toward the opening of the groove. The wide section and the narrow section are arranged sequentially along the direction from the bottom of the groove to the opening of the groove. In the locked state, the narrow section can provide reliable blocking, and in the triggered state, the wide section can provide a smooth passage path.

[0028] Specifically, such as Figure 3 As shown, the primary filtration chamber 10 includes a first chamber and a second chamber that are connected to each other. The second chamber gradually contracts away from the first chamber and is directly connected to the separation chamber 210. By setting the second chamber to a gradually contracting structure, large-diameter particles can automatically gather along the contraction slope under the action of gravity and be accurately introduced into the inlet of the separation chamber 210, avoiding the dispersion and accumulation of particles in the wide area at the bottom of the primary filtration chamber 10.

[0029] More specifically, the inner wall of the first cavity is provided with a guide surface 101, which is inclined towards the inlet of the second cavity. Through the combined action of the inclined guide surface 101 and the bottom contraction structure, large-diameter particles intercepted by the primary filter holes 11 automatically slide down along the guide surface 101 under the action of gravity, and are then gathered by the contraction slope and precisely guided into the inlet of the separation cavity 210, concentrating and falling into the cavity corresponding to the baffle plate 221 directly opposite the primary filter cavity 10. The combination of guidance and contraction further avoids particles from being dispersed and accumulated in the wide area or corners at the bottom of the primary filter cavity 10, thereby improving the efficiency of transferring large-diameter particles from the primary filter cavity 10 to the separation cavity 210.

[0030] Specifically, such as Figure 3 As shown, the stop member 24 includes a rod 241 and two pulleys 242. One end of the rod 241 is hinged to the corresponding baffle plate 221, and the other end is rotatably connected to the pulleys 242 on opposite sides along the width direction. The two pulleys 242 can pass through the wide section of the T-shaped hole 230, and the rod 241 can pass through the narrow section of the T-shaped hole 230. When the weight of the large particles exceeds the preload of the first elastic member 25, the end of the stop member 24 moves towards the T-shaped hole 230 under the action of thrust. At this time, the pulleys 242 roll forward along the surface of the stop plate 23, avoiding wear and jamming caused by direct sliding friction between the end of the stop member 24 and the stop plate 23, so that the stop member 24 can enter the T-shaped hole 230 with lower resistance and more stable operation. Then, the pulleys 242 enter the wide section first and pass through, and the rod 241 slides out along the narrow section, realizing the sequential action of limit release and baffle plate 221 flipping, making the unloading process stable and controllable. Meanwhile, during the process of rotating component 22 switching chambers, the pulleys 242 at the ends of each stop component 24 always abut against the inner wall of the separation chamber 210 and roll along it, which also converts sliding friction into rolling friction, reduces the running resistance of rotating component 22, and avoids wear and jamming caused by direct sliding friction between the end of rod 241 and the cavity wall.

[0031] Specifically, such as Figure 3 As shown, the first elastic element 25 is rotatably mounted on the corresponding baffle plate 221 via the hinge support 26. By forming a rotatable connection between the end of the first elastic element 25 and the hinge support 26, the first elastic element 25 can adaptively adjust its angle with the swing of the stop member 24 during the flipping process of the baffle plate 221, thus avoiding bending deformation or uneven force due to the fixed end of the first elastic element 25.

[0032] In this embodiment, the hinge support 26 includes two spaced-apart ear plates with symmetrical rotating holes on the two ear plates. One end of the first elastic member 25 along its length is provided with a connector, which is placed between the two ear plates and rotatably installed in the two rotating holes by a pin, so that the end of the first elastic member 25 is hingedly connected to the hinge support 26; the other end of the first elastic member 25 is connected to the middle of the rod 241 of the stop member 24.

[0033] In this embodiment, the rod 241 is also rotatably mounted on the corresponding baffle plate 221 via the hinge support 26.

[0034] Specifically, such as Figure 1 and Figure 4 As shown, the pre-separation device of the deep-sea mining organization also includes a filter assembly 4. The filter assembly 4 includes a shell 41, a filter cylinder 42, a drive unit 43, and a stirrer 44. The shell 41 is connected to the bottom of the shell 21 and has a filter chamber 410 communicating with the discharge. The shell 41 is connected to the primary filter cylinder 1 and the deep water pump 200. The filter cylinder 42 is located in the filter chamber 410 and has an opening on its top surface communicating with the discharge port. The filter cylinder 42 has several filter holes 420 on its peripheral wall for intercepting large-diameter particles. The filter cylinder 42 has an outlet on its bottom surface. The storage box 3 is connected to the bottom of the shell 41 and communicates with the outlet. The drive unit 43 is installed in the storage box 3. The stirrer 44 is connected to the output end of the drive unit 43 and extends into the filter cylinder 42 through the outlet. The driving component 43 drives the stirring component 44 to rotate continuously inside the filter cylinder 42. This disperses the pseudo-large diameter particle aggregates formed by small-diameter particles due to mineral adhesion or hydraulic flocculation, causing them to deagglomerate and return to a state of individual small particles with the required diameter, allowing them to pass smoothly through the filter holes 420. This prevents such pseudo-large diameter particles from being mistakenly intercepted and entering the collection box 3, thus avoiding the loss of useful minerals. The diameter of the filter holes 420 can be the same as or smaller than the diameter of the primary filter holes 11. It can be flexibly set according to actual needs.

[0035] In this embodiment, the outer shell 41 is connected to the primary filter cartridge 1 and the deep water pump 200 respectively through a conduit. The conduit between the outer shell 41 and the primary filter cartridge 1 is arranged at the position where the primary filter cartridge 1 has a primary filter hole 11. An annular gap is formed between the inner wall of the outer shell 41 and the outer wall of the filter cartridge 42. Small diameter particles pass through the filter hole 420, pass through the annular gap, and flow out through the conduit into the deep water pump 200.

[0036] More specifically, the filter assembly 4 also includes a plurality of baffles 45 arranged vertically at intervals within the filter cylinder 42, with the projections of adjacent baffles 45 in the vertical direction not overlapping. The stirring component 44 includes a rotating rod 441 and a plurality of stirring rods 442. The rotating rod 441 is connected to the output end of the drive component 43, and the plurality of stirring rods 442 are arranged axially at intervals on the rotating rod 441, and each abuts against the top surface of the plurality of baffles 45. The arrangement of the plurality of baffles 45 creates a zigzag flow channel inside the filter chamber 410, guiding the mixed particles downwards layer by layer along the zigzag path, effectively extending the residence time of the particles in the filter cylinder 42. This allows small-diameter particles trapped between large-diameter particles and individual small-diameter particles released after being stirred and dispersed to have sufficient opportunity to seep out from the filter holes 420 during the zigzag process, achieving full separation of large-diameter and small-diameter particles. Meanwhile, as the stirring rod 442 rotates with the rotating rod 441, it abuts against the top surface of each partition 45 one by one, sweeping the large particles placed on the top surface of the partition 45 downward layer by layer, preventing the particles from accumulating on the partition 45 and blocking the flow channel, so that they can smoothly enter the storage box 3.

[0037] In this embodiment, each partition 45 covers half of the cross-section of the filter cylinder 42, and a groove is provided on the side facing the rotating rod 441 for the rotating rod 441 to pass through.

[0038] More specifically, such as Figure 4As shown, the pre-separation device of the deep-sea mining mechanism also includes a temporary storage component 5. The temporary storage component 5 includes a temporary storage box 51, a fixed plate 52, a rotating plate 53, and a second elastic member 54. The temporary storage box 51 is connected to the inner top wall of the storage box 3 and has an inlet with a connecting outlet on the top surface and a discharge outlet on the bottom surface. The fixed plate 52 is connected to the inner side wall of the temporary storage box 51 and extends obliquely to the discharge outlet. The rotating plate 53 includes a first plate body, a shaft part, and a second plate body part connected in sequence. The rotating plate 53 is rotatably set at the discharge outlet through the shaft part, and the shaft part abuts against the lower end of the fixed plate 52. The second elastic member 54 connects the first plate body part and the fixed plate 52. In the initial state, the second elastic member 54 is in a natural state, and the second plate body part and the fixed plate 52 jointly cover the discharge outlet. The inclined setting of the fixed plate 52 can guide large-diameter particles to fall onto the second plate body. When the large-diameter particles on the second plate body accumulate to the set weight, the rotating plate 53 overcomes the pre-tightening force of the second elastic element 54 and flips downward, releasing the particles to the bottom of the collection box 3. Then, under the action of the second elastic element 54, it automatically resets. This intermittent discharge mechanism can reduce the impact of falling particles and prevent external fluids from entering the temporary storage box 51, thus improving the stability and reliability of the collection process.

[0039] In this embodiment, both the second elastic element 54 and the first elastic element 25 are springs, and their elastic coefficients can be flexibly configured according to actual working conditions without specific limitations.

[0040] More specifically, the temporary storage box 51 is equipped with a mounting plate 55, which is parallel to the fixed plate 52. The stirring component 44 is rotatably inserted through the mounting plate 55, with one end extending into the filter cylinder 42 and the other end connected to the output end of the drive component 43. Large-diameter particles discharged from the bottom outlet of the filter cylinder 42 fall into the temporary storage box 51 and slide down the inclined surface of the mounting plate 55, accurately guiding them to accumulate on the second plate body. This ensures that the weight of the large-diameter particles can effectively act on the second plate body, thereby accurately triggering the rotation of the rotating plate 53 and discharging them. Furthermore, the parallel arrangement provides installation space for the drive component 43 and protects it between the mounting plate 55 and the fixed plate 52, preventing damage to the drive component 43. The drive component 43 is a motor.

[0041] In this embodiment, the mounting plate 55 is provided with a guide portion that bends toward the second plate body. The guide portion extends vertically to the top of the discharge port, so that when the particles sliding down the top surface of the mounting plate 55 reach its lower end, the guide portion changes the falling direction and guides them to be discharged in a concentrated manner in the area directly below the discharge port. Furthermore, due to the addition of the guide portion, it can further prevent particles from entering between the mounting plate 55 and the fixing plate 52 and damaging the drive component 43.

[0042] More specifically, such as Figure 1 and Figure 4As shown, the pre-separation device of the deep-sea mining mechanism also includes a workbench 6, which is mounted on the track support of the ore collection vehicle. The outer shell 41 and the filter cylinder 42 are mounted on the top surface of the workbench 6, and the storage box 3 is mounted on the bottom surface of the workbench 6. The workbench 6 serves as a load-bearing foundation, providing a stable mounting support for the filter assembly 4 and the storage box 3, ensuring the relative position fixation and connection reliability of each component in the vibration environment of deep-sea mining operations, while simplifying the assembly and positioning process of the equipment on the ore collection vehicle.

[0043] In this embodiment, the bottom of the outer shell 41 and the bottom of the filter cylinder 42 are both open structures, and the top of the storage box 3 is also an open structure. The workbench 6 has a through hole at the position of the bottom outlet of the filter cylinder 42. The opening at the bottom of the filter cylinder 42 is directly connected to the opening at the top of the storage box 3 through the through hole, so that the large-diameter particles intercepted in the filter cylinder 42 can fall smoothly into the storage box 3.

[0044] In this embodiment, the mounting plate 55 is connected to the bottom surface of the workbench 6.

[0045] In this embodiment, the deep water pump 200 is disposed on the top surface of the workbench 6.
