Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0022] See also Figure 1-Figure 7 The present invention provides an embodiment: a diversion mechanism of a permanent magnet submersible sewage pump for mining, comprising a diversion volute 100, a pump body 200 for applying a driving force fixedly mounted on the top of the diversion volute 100, a base 300 for stable placement fixedly mounted on the bottom of the diversion volute 100, a water outlet 400 for drainage fixedly mounted on the side of the diversion volute 100, a main shaft 500 rotatably mounted between the pump body 200 and the diversion volute 100, an impeller 600 mounted on the main shaft 500 near the outer surface of the diversion volute 100, at least six blades 700 provided on the side of the impeller 600 in an annular array, the impeller 600 comprising a driving assembly 610, a diversion adjustment assembly 620, a cleaning assembly 630, and a crushing and cutting assembly 640; It should be noted that the sewage electric pump can be stably placed in a designated position through the base 300. After placement, when the pump body 200 is working, it drives the main shaft 500 to rotate. When the main shaft 500 rotates, it drives the impeller 600 and the blades 700 to rotate. When the blades 700 rotate, the sewage can be drawn into the interior of the diversion volute 100 through the base 300. After the sewage enters the interior of the diversion volute 100, it can be discharged through the water outlet 400; when it is necessary to adjust the angle of the blade 700, the drive component 610 is started to make the diversion adjustment component 620 work. When the diversion adjustment component 620 is working, the angle of the blade 700 can be adjusted according to different water conditions. When the drive component 610 is working, the cleaning component 630 can also be started to clean the sludge on the inner wall of the diversion volute 100. When the sewage enters the interior of the diversion volute 100, the crushing and cutting component 640 can crush and cut larger gravel and fiber in the sewage.

[0023] like Figure 2 and Figure 3 As shown, the drive assembly 610 also includes a telescopic rod 611, a motor 612 and a first gear 613. The telescopic rod 611 is fixedly installed on the top of the inner cavity of the impeller 600. The output end of the telescopic rod 611 is fixedly installed with the motor 612 through an assembly frame. The output end of the motor 612 is installed with a first gear 613 that cooperates with the second gear 615. When the telescopic rod 611 is working, it can drive the first gear 613 to freely switch between the two second gears 615. When the telescopic rod 611 is working, the assembly bracket at the output end can drive the motor 612 and the first gear 613 to move vertically. When the first gear 613 moves vertically, it can switch between the two second gears 615. When the first gear 613 moves to the side of the designated second gear 615, the motor 612 works to drive the first gear 613 to rotate. When the first gear 613 rotates, it drives the second gear 615 to engage and rotate.

[0024] like Figure 2-Figure 4 As shown, the drive assembly 610 includes a sleeve 614 and a second gear 615. There are two sleeves 614. The first sleeve 614 is sleeved on the outer surface of the main shaft 500, and the second sleeve 614 is sleeved on the outer surface of the first sleeve 614. The second sleeve 614 is shorter than the first sleeve 614, and the second sleeve 614 is rotatably mounted on the top of the inner cavity of the impeller 600 through an assembly frame. The outer surfaces of the two sleeves 614 are fixedly mounted with second gears 615. When the two second gears 615 rotate, they can respectively drive the two sleeves 614 to rotate. When the two sleeves 614 rotate, they can respectively drive the diversion adjustment assembly 620 and the cleaning assembly 630 to work. It is worth noting that when the first gear 613 moves to the side of the second gear 615 at the top, the first gear 613 rotates, driving the second gear 615 at the top to engage and rotate. When the second gear 615 at the top engages and rotates, it drives the first sleeve 614 to rotate on the side of the main shaft 500. When the first sleeve 614 rotates, it drives the cleaning assembly 630 to work. When the first gear 613 moves to the side of the second gear 615 at the bottom, the first gear 613 rotates, driving the second gear 615 at the bottom to engage and rotate. When the second gear 615 at the bottom engages and rotates, it drives the second sleeve 614 to rotate on the outer surface of the first sleeve 614. When the second sleeve 614 rotates, it can rotate on the top of the inner cavity of the impeller 600 through the assembly bracket. When the second sleeve 614 rotates, it drives the diversion adjustment component 620 to work.

[0025] like Figure 2-Figure 4 As shown, the diversion adjustment assembly 620 also includes a first bevel gear 621, a second bevel gear 622 and a rotating rod 623. The first bevel gear 621 is fixedly mounted on the outer surface of the second sleeve 614. The other ends of the six rotating columns 624 are fixedly mounted with the rotating rod 623. The other ends of the rotating rods 623 are fixedly mounted with the second bevel gear 622 that matches the first bevel gear 621. When the second sleeve 614 rotates, it drives the first bevel gear 621 on the surface to rotate. When the first bevel gear 621 rotates, it drives the second bevel gear 622 to rotate. When the second bevel gear 622 rotates, it drives the rotating rod 623 to rotate. When the rotating rod 623 rotates, it drives the rotating column 624 to rotate inside the impeller 600.

[0026] like Figure 2 、 Figures 4-10 As shown, the flow guide adjustment assembly 620 includes a rotating column 624. At least six rotating columns 624 are rotatably installed in an annular array through the inner cavity of the impeller 600. One end of each rotating column 624 is fixedly connected to the blade 700. The rotating column 624 can adjust the angle of the blade 700 by rotating. The angle adjustment of the blade 700 can adapt to different water conditions. When the rotating column 624 rotates, it rotates inside the impeller 600. When the rotating column 624 rotates, the angle of the blade 700 can be adjusted. The angle of the blade 700 is usually based on the "blade 700 outlet angle" (the angle between the tangent line of the blade 700 outlet edge and the tangent line of the impeller 600 circumference) as the core parameter. The blade 700 is divided into backward blades 700 (outlet angle <90°), radial blades 700 (outlet angle ≈90°) and forward blades 700 (outlet angle >90°), which have a significant impact on the energy conversion of the water flow. Backward blades 700: Blades 700 are tilted in the opposite direction of impeller 600's rotation (e.g., an outlet angle of 30°-60°). Water flows primarily radially from impeller 600, with a smaller "circumferential component" and a larger "radial component" of its absolute velocity. In this configuration, the kinetic energy of the water is minimal, with more energy being transferred directly as pressure energy. This results in high energy conversion efficiency (typically reaching a peak efficiency of 70%-90%), making it suitable for applications requiring high flow rates and low to medium lifts. Forward blades 700: Blades 700 are tilted toward the direction of rotation of the impeller 600 (e.g., an outlet angle of 100°-160°). The water has a large "circumferential component" when it flows out, and its kinetic energy accounts for a high proportion. This kinetic energy must be further converted into pressure energy by the guide volute 100, thereby generating a higher head. However, this results in significant energy conversion losses (typically less than 70% efficiency), making it suitable for low-flow, high-head scenarios. Radial blades 700: Blades 700 are arranged radially, between the forward and backward directions. They have medium lift and efficiency, simpler structure, and stronger anti-clogging ability. They are often used in sewage pumps containing more impurities.

[0027] like Figure 2-Figure 7As shown, the cleaning assembly 630 also includes a rotating disk 631, an oblique push groove 632, a moving rod 633, a bearing 634 and a push rod 635. The bottom end of the first sleeve 614 is fixedly mounted with a rotating disk 631, and the rotating disk 631 is rotatably mounted on the bottom of the inner cavity of the impeller 600. The outer surface of the rotating disk 631 is provided with at least six oblique push grooves 632 in a circular array. The interior of the oblique push groove 632 is movably connected with the moving rod 633. The top of the moving rod 633 is installed with a bearing 634, and the bearing 634 is movably mounted on the rotating rod 623. A push rod 635 is movably mounted between the rotating rod 623, the rotating column 624 and the blade 700. One end of the push rod 635 is fixedly connected to the inner ring of the bearing 634 through an assembly block. There are six push rods 635, and a sliding groove is provided on the surface of the rotating rod 623 for allowing the assembly block to move horizontally. It should be noted that when the first sleeve 614 rotates, it drives the rotating disk 631 at the bottom to rotate, and when the rotating disk 631 rotates, it drives the oblique push groove 632 to rotate. When the oblique push groove 632 rotates, it can push the moving rod 633, thereby driving the bearing 634 to move horizontally on the rotating rod 623. When the bearing 634 moves horizontally, it drives the push rod 635 to slide inside the rotating rod 623, the rotating column 624 and the blade 700 through the cooperation of the assembly block and the slide groove.

[0028] like Figure 1-Figure 3 and Figure 4-Figure 7 As shown, the cleaning assembly 630 includes a sidewall cleaning plate 636, a corner cleaning plate 6310, and an upper and lower cleaning plate 6314. The side of the two blades 700 away from the rotating column 624 is movably mounted with the sidewall cleaning plate 636 through an assembly slot. The arc-shaped corners of the two blades 700 are movably mounted with the corner cleaning plates 6310 through an assembly slot. The top and bottom of the two blades 700 are movably mounted with the upper and lower cleaning plates 6314 through an assembly slot. When the sidewall cleaning plate 636, the corner cleaning plate 6310, and the upper and lower cleaning plates 6314 extend out of the blade 700 assembly slot, they can clean the inner wall of the guide volute 100. When it is necessary to clean the inner wall of the guide volute 100, the side wall cleaning plate 636, the corner cleaning plate 6310 and the upper and lower cleaning plates 6314 can be extended out of the interior of the blade 700. At this time, the impeller 600 rotates, driving the blade 700 to rotate. When the blade 700 rotates, it drives the side wall cleaning plate 636, the corner cleaning plate 6310 and the upper and lower cleaning plates 6314 to rotate. When the side wall cleaning plate 636 rotates, the inner wall side of the guide volute 100 can be cleaned. When the corner cleaning plate 6310 rotates, the curved surface of the inner wall of the guide volute 100 can be cleaned. When the upper and lower cleaning plates 6314 rotate, the top and bottom of the inner wall of the guide volute 100 can be cleaned.

[0029] like Figure 1-Figure 7As shown, the cleaning assembly 630 further includes a first extended cleaning plate 637. One side of the two side wall cleaning plates 636 is fixedly connected to one end of two of the push rods 635. The first extended cleaning plate 637 is movably mounted on the surface of the side wall cleaning plate 636 through an assembly groove and an elastic member. It is worth noting that the two push rods 635 can move horizontally within the blade 700 when they move. When the push rod 635 moves, it can push the side wall cleaning plate 636 to slide in the assembly groove of the blade 700. When the side wall cleaning plate 636 slides, it drives the first extended cleaning plate 637 to move. When the side wall cleaning plate 636 and the first extended cleaning plate 637 slide out of the assembly groove of the blade 700, the first extended cleaning plate 637 can slide inside the assembly groove of the side wall cleaning plate 636 through the cooperation of the elastic part. When the side wall cleaning plate 636 and the first extended cleaning plate 637 move to the specified position, they will contact the inner wall side of the guide volute 100. When the blade 700 rotates, it drives the side wall cleaning plate 636 and the first extended cleaning plate 637 to clean the inner wall side of the guide volute 100.

[0030] like Figure 1-Figure 7 As shown, the cleaning assembly 630 also includes a push plate 638 and a first extension rod 639, wherein the push plates 638 are movably mounted on the inner sides of the two blades 700 near the corner cleaning plate 6310 through the assembly groove, and one side of the two push plates 638 is fixedly connected to one end of the two push rods 635, and the other side of the push plate 638 is symmetrically and movably mounted with two first extension rods 639 through the assembly groove, and the other end of the first extension rod 639 passes through the assembly hole of the blade 700 and is fixedly connected to the corner cleaning plate 6310; When the two push rods 635 move, they can push the push plate 638 to slide horizontally in the assembly groove of the blade 700. When the push plate 638 slides, it can push the first extension rod 639 to slide in the assembly hole of the blade 700. When the first extension rod 639 slides in the assembly hole of the blade 700, one end of the first extension rod 639 will slide on the assembly groove of the push plate 638, and the other end can push the corner cleaning plate 6310 to slide in the assembly groove of the blade 700. When the corner cleaning plate 6310 moves to the corner of the inner wall of the diversion volute 100, the rotation of the blade 700 drives the corner cleaning plate 6310 to clean the corner of the inner wall of the diversion volute 100.

[0031] like Figure 1-Figure 7As shown, the cleaning assembly 630 also includes a pushing seat 6311, a connecting rod 6312, a second extension rod 6313 and a second extension plate 6315, wherein the two blades 700 are movably mounted with the pushing seat 6311 on the inner sides close to the upper and lower cleaning plates 6314 through an assembly groove, one side of the pushing seat 6311 is fixedly connected to one end of the two push rods 635, and two connecting rods 6312 are symmetrically rotatably mounted on the other side of the pushing seat 6311, the other end of the connecting rod 6312 is rotatably connected to the second extension rod 6313, the other end of the second extension rod 6313 passes through the assembly hole of the blade 700 and is fixedly connected to the upper and lower cleaning plates 6314, and the second extension plate 6315 is movably mounted on the surface of the upper and lower cleaning plates 6314 through an assembly groove and an elastic member; It should be noted that when the two push rods 635 move, they will push the push seat 6311 to move horizontally in the assembly groove of the blade 700. When the push seat 6311 moves horizontally, it will push the connecting rod 6312 to rotate. When the connecting rod 6312 moves, it will push the second extension rod 6313 to move vertically in the assembly hole of the blade 700. When the second extension rod 6313 moves vertically, it will push the upper and lower cleaning plates 6314 to move vertically in the assembly groove of the blade 700. When the upper and lower cleaning plates 6314 move vertically, The second extension plate 6315 is moved vertically. After the second extension plate 6315 is removed from the assembly groove of the blade 700, the two second extension plates 6315 can be horizontally expanded to both sides in the assembly groove of the upper and lower cleaning plates 6314 through the cooperation of the elastic parts. When the upper and lower cleaning plates 6314 and the second extension plate 6315 move to the top and bottom of the inner wall of the guide volute 100, the blade 700 drives the upper and lower cleaning plates 6314 and the second extension plate 6315 to clean the top and bottom of the inner wall of the guide volute 100 when it rotates.

[0032] like Figures 1-4 As shown, the crushing and cutting assembly 640 includes a water inlet 641, an annular extrusion seat 642, a corrugated groove 643, a guide frame 644 and an annular rack 645. The water inlet 641 is fixedly installed at the bottom center of the guide volute 100, and the upper edge of the water inlet 641 extends to the assembly groove at the bottom of the impeller 600. The gap between the water inlet 641 and the assembly groove at the bottom of the impeller 600 forms a water inlet chamber. The top of the water inlet 641 is movably installed with an annular extrusion seat 642 through the assembly groove. The inner side wall of the annular extrusion seat 642 is provided with a corrugated groove 643. The inside of the corrugated groove 643 is movably connected with at least four guide frames 644 located on the same horizontal plane. The other end of the guide frame 644 is fixedly installed in the assembly groove at the bottom of the impeller 600. Annular racks 645 are fixedly installed in the top of the annular extrusion seat 642 and the assembly groove at the bottom of the impeller 600. The two annular racks 645 have the same axis. It should be noted that the ore sewage can enter the water inlet chamber through the water inlet 641 at the bottom of the guide volute 100 and be transported to the guide volute 100 through the water inlet chamber. Gravel will remain inside the ore sewage. When large-volume gravel enters the guide volute 100, it will damage the blades 700 and needs to be crushed. When the size of the gravel is larger than the gap between the water inlet 641 and the annular extrusion seat 642, it will be stuck. At this time, the impeller 600 rotates. The annular rack 645 is driven to rotate. When the annular rack 645 rotates, it will crush the gravel together with the annular rack 645 on the top of the annular extrusion seat 642. When the impeller 600 rotates, it drives the guide frame 644 to rotate. When the guide frame 644 rotates, it will slide in the corrugated groove 643. When the guide frame 644 slides in the corrugated groove 643, it will push the annular extrusion seat 642 to rise and fall in the assembly groove of the water inlet 641. When the annular extrusion seat 642 rises and falls, the gravel will be crushed.

[0033] like Figure 2 and Figure 4 As shown, the crushing and cutting assembly 640 further includes a fixed blade 646 and a rotating blade 647. At least six fixed blades 646 are fixedly mounted in an annular array on the outer surface of the water inlet 641. At least six rotating blades 647 are fixedly mounted in an annular array on the inner wall of the assembly groove at the bottom of the impeller 600. The bottoms of the rotating blades 647 are in contact with the tops of the fixed blades 646. When the impeller 600 rotates, the rotating blade 647 is driven to rotate. When the rotating blade 647 rotates, the long fibers can be cut by the cooperation of the fixed blade 646, thereby preventing the long fibers from being entangled with the impeller 600 and the blades 700.
