[0001] The invention relates to the technical field of water pumps, in particular to a submersible pump. Background Art

[0002] Submersible pumps are important equipment for deep well water extraction. When in use, the entire unit submerges in the water to extract groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. Hot water submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells, and can also be used in water extraction projects such as rivers, reservoirs, and canals.

[0003] Submersible pumps can pump water smoothly when placed in waters with fewer impurities and plants. However, when there are more impurities and plants in the water source, it is easy to cause the deep water pump to be blocked, thereby affecting the deep water pump's extraction of water, and in severe cases causing the deep water pump to be damaged. Summary of the invention

[0004] In order to solve the problem that under the prior art, a submersible pump can pump water smoothly when placed in a water area with fewer impurities and plants, but when there are more impurities and plants in the water source, it is easy to cause the deep water pump to be blocked, thereby affecting the deep water pump's extraction of water, and seriously causing the deep water pump to be damaged, the present application provides a submersible pump, and the specific solution is as follows.

[0005] A submersible pump comprises a body, a water inlet is provided at the bottom of the body, a water outlet is provided on the side wall of the body, an impeller is provided at the water inlet of the body, the impeller is used to extract the medium at the water inlet to the water outlet, a motor is provided inside the body for driving the impeller to rotate, and the rotating shaft of the motor is fixedly connected to the impeller; A mixing knife is also arranged at the bottom of the main body. The mixing knife is detachably connected to the impeller and can rotate along with the impeller. The mixing knife extends out of the water suction port of the main body.

[0006] By adopting the above technical solution, the submersible pump can effectively cut larger impurities or plants in the water during the water extraction process to avoid clogging the water inlet and outlet, thereby ensuring the normal operation of the water pump. The setting of the mixing knife enables the submersible pump to have the ability to preliminarily process debris in the water. Its detachable connection with the impeller facilitates replacement and maintenance. At the same time, the design of the mixing knife extending out of the water outlet further improves the cutting efficiency and range.

[0007] Optionally, a guide groove is provided at the bottom of the mixing knife, and the guide groove is used to guide the cut plants.

[0008] By adopting the above technical solution, the guide groove at the bottom of the mixing knife can effectively guide the cut plant residues to move in a specific direction, avoiding the accumulation of plant residues near the water pump after cutting, thereby reducing the risk of blockage and improving the working efficiency and stability of the submersible pump.

[0009] Optionally, a connecting rod is provided on the upper part of the mixing knife, and the connecting rod is used to be fixedly connected to the impeller. The mixing knife is arranged at the bottom end of the connecting rod. The mixing knives are arranged at equal intervals along the circumference of the connecting rod, and the mixing knives are all threadedly connected to the connecting rod.

[0010] By adopting the above technical solution, a stable connection between the mixing knife and the impeller is achieved, and the installation and removal of the mixing knife is convenient. The design of the connecting rod ensures that the mixing knife is fixed in position, so that it can effectively follow the rotation of the impeller to perform cutting operations. The mixing knives are arranged at equal intervals along the circumference of the connecting rod, ensuring uniform force, improving cutting efficiency and stability, and the threaded connection makes it easier to adjust the angle of the mixing knife. During normal cutting, the mixing knife can be rotated to adjust the angle, which improves versatility. When encountering debris that is difficult to cut, the mixing knife can be rotated to avoid it, reducing the possibility of damage to the mixing knife.

[0011] Optionally, the mixing knife is provided with a connecting rod in which an adjusting rod is also provided, the adjusting rod is rotatably connected to the connecting rod, a clearance groove is provided on the connecting rod corresponding to the adjusting rod, an adjusting handle is provided at the position of the clearance groove corresponding to the adjusting rod, the adjusting handle is fixedly connected to the adjusting rod, the adjusting handle can slide along the clearance groove, a bevel gear is provided at the bottom of the adjusting rod, and corresponding matching gears are also provided on each of the mixing knives, and the bevel gears are meshed with the matching gears.

[0012] By adopting the above technical scheme, the submersible pump can flexibly adjust the angle of the mixing knife during operation. The rotating connection between the adjusting rod and the connecting rod is matched with the design of the giveway groove, so that the adjusting handle can slide along the giveway groove, thereby driving the bevel gear to rotate. The meshing transmission between the bevel gear and the matching gear further realizes the angle adjustment of the mixing knife, and can drive each mixing knife to achieve synchronous angle adjustment. This design enhances the ability to cope with different working conditions during cutting.

[0013] Optionally, a pushing member is fixedly provided on the connecting rod, and the pushing member is used to drive the adjusting handle to slide. A torque sensor is also provided inside the main body, and the torque sensor is electrically connected to the pushing member. When the torque sensor detects an increase in torque, the pushing member pushes the adjusting handle to move.

[0014] By adopting the above technical solution, when the stirring blade encounters harder or more sundries, resulting in an increase in torque, the torque sensor can detect this change in a timely manner, and drive the adjusting handle to slide along the relief groove through the pushing member. The movement of the adjusting handle drives the adjusting rod to rotate, and then adjusts the angle or position of the stirring blade by using the meshing relationship between the bevel gear and the mating gear, thereby effectively avoiding the situation of equipment damage caused by excessive resistance, and improving the stability and reliability of the submersible pump operation.

[0015] Optionally, a spiral tungsten carbide blade is further arranged on the connecting rod. The spiral tungsten carbide blade is spirally arranged around the circumference of the connecting rod. A plurality of spiral tungsten carbide blades are arranged at equal intervals around the circumference of the connecting rod. The spiral tungsten carbide blade is fixedly connected to the connecting rod. The spiral tungsten carbide blade is arranged on the lower side of the adjusting handle.

[0016] By adopting the above technical solution, the spiral tungsten carbide blade can form a tight protection when rotating, and the spiral tungsten carbide blade is arranged on the lower side of the adjusting handle, which can protect the adjusting handle, reduce the damage of the adjusting handle and the pushing member, and the spiral tungsten carbide blade can effectively cut and crush relatively hard sundries such as stones and shells, thereby reducing the situation of damage to the inside of the body caused by the entry of hard sundries such as stones and shells.

[0017] Optionally, a self-cleaning blade is further arranged on the connecting rod. The self-cleaning blade is arranged between the spiral tungsten carbide blade and the adjusting handle. A plurality of self-cleaning blades are arranged at equal intervals around the connecting rod.

[0018] By adopting the above technical solution, the self-cleaning blade refers to a blade made of acrylic material. Acrylic has an easy-to-clean property. Acrylic can cut and sweep out viscous substances, reduce the situation of viscous substances entering the body, and also reduce the situation of viscous substances adhering to the self-cleaning blade.

[0019] Optionally, a filter cover is further arranged at the bottom of the body. The filter cover is fixedly connected to the body. The filter cover is rotatably connected to the connecting rod. The filter cover wraps the adjusting handle inside.

[0020] By adopting the above technical solution, the setting of the filter cover can effectively prevent external impurities from entering the inside of the body, and protect the adjusting handle and other precision components from damage. At the same time, the rotatable connection design of the filter cover and the connecting rod ensures the normal operation of the stirring blade and does not affect the operation flexibility of the adjusting handle. This structure improves the overall stability and reliability of the submersible pump and extends the service life of the equipment.

[0021] Optionally, the self-cleaning blade is also arranged inside the filter cover. The spiral tungsten carbide blade and the stirring blade are both arranged outside the filter cover. The self-cleaning blade abuts against the inner wall of the filter cover.

[0022] By adopting the above technical solution, the spiral tungsten blade and the stirring knife are arranged outside the filter cover, which can effectively cut the sundries on the lower side of the main body, reduce the situation that the filter cover is completely blocked by sundries or damaged by colliding with the filter cover. The self-cleaning blade is used to clean the jelly-like substances, so it is arranged inside the filter cover, which can push the viscous substances towards the filter cover. At the same time, the self-cleaning blade can also clean the filter cover, reducing the situation that sundries adhere to the filter cover and affect the water pumping.

[0023] Optionally, a plurality of shark teeth protrude from the stirring knife, and the shark teeth are arranged at equal intervals along the stirring knife.

[0024] By adopting the above technical solution, the shark teeth can cut sundries more effectively, further reducing the situation that sundries are wound around the stirring knife, and further improving the cutting effect.

[0025] In summary, the present application has at least the following beneficial effects: The present application solves the problem that the existing submersible pump can pump water smoothly when placed in a water area with less impurities and plants, but when there are more impurities and plants in the water source, it is easy to cause the deep water pump to be blocked, thus affecting the extraction of water source by the deep water pump, and seriously may cause the deep water pump to be damaged. The present application cuts the products below the main body by setting a stirring knife, thereby reducing the situation of sundries winding and blocking the water inlet. The present application also sets multi-stage blades to cut different sundries in stages, which can effectively cut a variety of sundries, and further reduce the situation that different sundries affect the inside of the main body.

Detailed implementation manners

[0031] The present application will be further described in detail below with reference to the accompanying drawings and through specific embodiments.

[0032] A submersible pump, as Figure 1 and Figure 2 shown, includes a main body 1. A water pumping port 11 is opened at the bottom of the main body 1, and a water outlet 12 is provided on the side wall of the main body 1. An impeller 13 is arranged at the water pumping port 11 of the main body 1. The impeller 13 is used to pump the medium at the water pumping port 11 to the water outlet 12. A motor for driving the impeller 13 to rotate is arranged inside the main body 1, and the rotating shaft of the motor is fixedly connected to the impeller 13. During specific implementation, when pumping water, the rotation of the impeller 13 can pump the medium from the water pumping port 11 to the water outlet 12, and the medium at the water outlet 12 is led out through a connecting pipe or the like.

[0033] As Figure 2 and Figure 3 shown, a stirring knife 2 is further arranged at the bottom of the main body 1. The stirring knife 2 is detachably connected to the impeller 13. The stirring knife 2 can rotate along with the impeller 13 and extends out of the water pumping port 11 of the main body. A guiding groove 21 is opened at the bottom of the stirring knife 2. The guiding groove 21 is used to guide the cut plants. A plurality of shark teeth 23 protrude from the stirring knife 2, and the shark teeth 23 are arranged at equal intervals along the stirring knife 2. During specific implementation, the shark teeth 23 can effectively cut various sundries such as plants, limiters, and plastics. The guiding groove 21 can guide the water flow to a certain extent, provide a certain guidance for the cut sundries, so that the sundries can be sent out along the guiding direction, reduce the situation of sundries winding around the stirring knife 2, and reduce the situation of sundries entering the main body 1 and causing damage.

[0034] As Figure 2 and Figure 4 shown, a connecting rod 3 is arranged at the upper part of the stirring knife 2. The connecting rod 3 is used to be fixedly connected to the impeller 13. The stirring knife 2 is arranged at the bottom end of the connecting rod 3. The stirring knives 2 are arranged at equal intervals along the circumferential direction of the connecting rod 3, and the stirring knives 2 are all threadedly connected to the connecting rod 3. During specific implementation, the connecting rod 3 and the impeller 13 are connected by bolts. After connection, the connecting rod 3 can rotate along with the impeller 13, and the impeller 13 can drive the connecting rod 3 and the stirring knife 2 to rotate and cut.

[0035] As Figure 2 and Figure 4As shown, the mixing knife 2 is provided with a connecting rod 3 in which an adjusting rod 31 is also provided. The adjusting rod 31 is rotatably connected to the connecting rod 3. A clearance groove 35 is provided on the connecting rod 3 corresponding to the adjusting rod 31. An adjusting handle 312 is provided at the position of the adjusting rod 31 corresponding to the clearance groove 35. The adjusting handle 312 is fixedly connected to the adjusting rod 31. The adjusting handle 312 can slide along the clearance groove 35. A bevel gear 311 is provided at the bottom of the adjusting rod 31. Each mixing knife 2 is also provided with a corresponding matching gear 22. The bevel gear 311 meshes with the matching gear 22. In specific implementation, the rotation of the adjusting rod 31 can drive each mixing knife 2 to adjust, and a single adjusting rod 31 can adjust multiple mixing knives 2 to rotate synchronously at the same time, so that the angles of the mixing knives 2 are adjusted synchronously, and the mixing knives 2 with the same angle have a better cutting effect.

[0036] like Figure 2 and Figure 4 As shown, a pusher 32 is fixedly provided on the connecting rod 3, and the pusher 32 is used to drive the adjustment handle 312 to slide. A torque sensor 14 is also provided inside the body 1, and the torque sensor 14 is electrically connected to the pusher 32. When the torque sensor 14 detects that the torque increases, the pusher 32 pushes the adjustment handle 312 to move. The pusher 32 can be an electric push rod with a waterproof shell, and the adjustment handle 312 is adjusted by the electric push rod. At the same time, the torque sensor 14 can detect whether there are debris that affects the water pumping, and then the debris is better cut by adjusting the angle of the mixing knife 2, further reducing the impact of the debris on the water pumping.

[0037] like Figure 2 and Figure 4 As shown, a spiral tungsten blade 33 is also provided on the connecting rod 3, and the spiral tungsten blade 33 is spirally arranged around the connecting rod 3. A plurality of spiral tungsten blades 33 are arranged around the connecting rod 3 at equal intervals. The spiral tungsten blade 33 is fixedly connected to the connecting rod 3, and the spiral tungsten blade 33 is arranged on the lower side of the adjustment handle 312. In specific implementation, the spiral tungsten blade 33 can effectively cut debris after rotating, especially debris with higher hardness such as shells and stones, and can reduce the situation where the harder debris enters and causes damage to the body 1.

[0038] like Figure 2 and Figure 4 As shown, the connecting rod 3 is also provided with a self-cleaning blade 34, which is arranged between the spiral tungsten blade 33 and the adjustment handle 312, and a plurality of self-cleaning blades 34 are arranged at equal intervals around the connecting rod 3. In specific implementation, the self-cleaning blade 34 is made of acrylic material, which can cut and scrape out sticky substances. Acrylic has a certain self-cleaning effect, and sticky substances can also fall off the self-cleaning blade 34 relatively easily.

[0039] like Figure 2 andFigure 4 As shown, a filter cover 4 is also provided at the bottom of the main body 1. The filter cover 4 is fixedly connected to the main body 1 and rotatably connected to the connecting rod 3. The filter cover 4 wraps the adjusting handle 312 inside. The self-cleaning blade 34 is also arranged inside the filter cover 4, and the spiral tungsten blade 33 and the stirring blade 2 are both arranged outside the filter cover 4. The self-cleaning blade 34 abuts against the inner wall of the filter cover 4. During specific implementation, the filter cover 4 can more effectively isolate sundries. At the same time, the spiral tungsten blade 33 and the stirring blade 2 arranged on the outside cut the sundries that can cover the filter cover 4, thereby reducing the situation where the filter cover 4 is completely covered and affecting water pumping. The self-cleaning blade 34 can not only clean and scrape viscous substances, but also scrape the sundries on the filter cover 4, thereby reducing the situation where too many sundries adhere to the filter cover 4 and affecting water pumping.

[0040] Working principle: By setting multiple-stage blades, it can effectively cut different types of sundries, reducing the situation that sundries enter the main body 1 during water pumping and affecting the inside of the main body 1. At the same time, a protective cover is set, and some blades are arranged on the outside to reduce the situation where the protective cover is blocked. Some blades are arranged inside the protective cover to clean the inside of the protective cover and scrape out sundries, further improving the stability during use.

[0041] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
