Description

Technical Field

[0001] This invention relates to the field of water pump technology, and in particular to a submersible pump. Background Technology

[0002] Submersible pumps are essential equipment for deep well water extraction. During operation, the entire unit is submerged in water to extract groundwater to the surface. They are used for domestic water supply, mine rescue operations, industrial cooling, farmland irrigation, seawater lifting, ship ballast adjustment, and even in fountain landscaping. Hot water submersible pumps are used in hot spring baths and can also be used to extract groundwater from deep wells, as well as in water lifting projects in rivers, reservoirs, and canals.

[0003] Submersible pumps can pump water smoothly when placed in waters with few impurities and plants. However, when there are many impurities and plants in the water source, it is easy to cause blockage of the deep water pump, which will affect the pump's ability to extract water and may even damage the deep water pump. Summary of the Invention

[0004] To address the problem that while submersible pumps can smoothly pump water in waters with few impurities and vegetation, the presence of many impurities and vegetation in the water source can easily cause blockages, thus affecting the pump's ability to extract water and potentially damaging the pump, this application provides a submersible pump with the following specific solution.

[0005] A submersible pump includes a body, with a water inlet at the bottom of the body and a water outlet on the side wall of the body. An impeller is provided at the water inlet of the body, and the impeller is used to draw the medium at the water inlet to the water outlet. A motor for driving the impeller to rotate is provided inside the body, and the shaft of the motor is fixedly connected to the impeller.

[0006] The bottom of the main body is also provided with a stirring blade, which is detachably connected to the impeller. The stirring blade can rotate with the impeller and extends out of the water inlet of the main body.

[0007] By adopting the above technical solutions, the submersible pump can effectively cut larger impurities or plants in the water during the water extraction process, avoiding blockage of the water inlet and outlet, thereby ensuring the normal operation of the water pump. The setting of the stirring blade enables the submersible pump to have the ability to preliminarily treat impurities in the water. Its detachable connection with the impeller facilitates replacement and maintenance. At the same time, the design of the stirring blade extending out of the water inlet further improves the cutting efficiency and range.

[0008] Optionally, the bottom of the mixing blade is provided with a guide groove, which is used to guide the cut plant.

[0009] By adopting the above technical solution, the guide groove at the bottom of the mixing blade can effectively guide the plant residue after cutting to move in a specific direction, avoiding the accumulation of plant residue near the water inlet after cutting, thereby reducing the risk of blockage and improving the working efficiency and stability of the submersible pump.

[0010] Optionally, a connecting rod is provided on the upper part of the mixing blade, the connecting rod is used to fix it to the impeller, and the mixing blade is provided at the bottom end of the connecting rod. The mixing blades are arranged at equal intervals along the circumference of the connecting rod, and all the mixing blades are threaded to the connecting rod.

[0011] By adopting the above technical solution, a stable connection between the mixing blade and the impeller is achieved, while facilitating the installation and disassembly of the mixing blade. The design of the connecting rod ensures the fixed position of the mixing blade, enabling it to effectively follow the rotation of the impeller for cutting operations. The mixing blades are evenly spaced along the circumference of the connecting rod, ensuring uniform force distribution, improving cutting efficiency and stability. Furthermore, the threaded connection facilitates angle adjustment of the mixing blade. During normal cutting, the angle can be adjusted by rotating the mixing blade, increasing its versatility. When encountering difficult-to-cut debris, the mixing blade can rotate to avoid it, reducing the likelihood of damage to the mixing blade.

[0012] Optionally, the mixing blade is provided with a connecting rod and an adjusting rod inside. The adjusting rod is rotatably connected to the connecting rod. The connecting rod has a clearance groove corresponding to the adjusting rod. The adjusting rod has an adjusting handle corresponding to the clearance groove. The adjusting handle is fixedly connected to the adjusting rod and can slide along the clearance groove. The bottom of the adjusting rod is provided with a bevel gear. Each mixing blade is also provided with a corresponding mating gear. The bevel gear meshes with the mating gear.

[0013] By adopting the above technical solutions, the submersible pump can flexibly adjust the angle of the mixing blade during operation. The rotating connection between the adjusting rod and the connecting rod, along with the design of the relief groove, allows the adjusting handle to slide along the relief groove, thereby driving the bevel gear to rotate. The meshing transmission between the bevel gear and the mating gear further realizes the angle adjustment of the mixing blade and can drive each mixing blade to achieve synchronous angle adjustment. This design enhances the ability to cope with different working conditions during cutting.

[0014] Optionally, a pusher is also fixedly installed on the connecting rod. The pusher is used to drive the adjusting handle to slide. A torque sensor is also installed inside the body. The torque sensor is electrically connected to the pusher. When the torque sensor detects an increase in torque, the pusher pushes the adjusting handle to move.

[0015] By adopting the above technical solution, when the mixing blade encounters hard or numerous impurities, causing 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 via the pushing component. The movement of the adjusting handle drives the adjusting rod to rotate, thereby adjusting the angle or position of the mixing blade using the meshing relationship between the bevel gear and the mating gear. This effectively avoids equipment damage caused by excessive resistance and improves the stability and reliability of the submersible pump operation.

[0016] Optionally, the connecting rod is further provided with a spiral tungsten blade, which is spirally arranged around the connecting rod in a circumferential manner. Multiple spiral tungsten blades are arranged at equal intervals around the connecting rod in a circumferential manner. The spiral tungsten blades are fixedly connected to the connecting rod and are located on the lower side of the adjusting handle.

[0017] By adopting the above technical solution, the spiral tungsten blade can form a tight protection when rotating. The spiral tungsten blade is set on the lower side of the adjusting handle, which can protect the adjusting handle and reduce the damage to the adjusting handle and the pushing component. In addition, the spiral tungsten blade can effectively cut and crush relatively hard debris such as stones and shells, thereby reducing the possibility of hard debris such as stones and shells entering and causing damage to the inside of the body.

[0018] Optionally, the connecting rod is also provided with a self-cleaning blade, which is disposed between the spiral tungsten blade and the adjusting handle, and multiple self-cleaning blades are arranged at equal intervals around the connecting rod.

[0019] By adopting the above technical solutions, self-cleaning blades refer to blades made of acrylic material. Acrylic has easy-cleaning properties and can cut and sweep away sticky substances, reducing the possibility of sticky substances entering the body and also reducing the possibility of sticky substances adhering to the self-cleaning blade.

[0020] Optionally, a filter cover is also provided at the bottom of the main body. The filter cover is fixedly connected to the main body and rotatably connected to the connecting rod. The filter cover encloses the adjusting handle.

[0021] By adopting the above technical solutions, the filter cover effectively prevents external impurities from entering the pump body, protecting the adjusting handle and other precision components from damage. Simultaneously, the rotatable connection between the filter cover and the connecting rod ensures that the stirring blade operates normally without affecting the operational flexibility of the adjusting handle. This structure enhances the overall stability and reliability of the submersible pump, extending its service life.

[0022] Optionally, the self-cleaning blade is also disposed inside the filter cover, while the spiral tungsten blade and the mixing blade are disposed outside the filter cover, and the self-cleaning blade abuts against the inner wall of the filter cover.

[0023] By adopting the above technical solution, the spiral tungsten blade and the stirring blade are set on the outside of the filter cover, which can effectively cut the debris on the lower side of the body and reduce the situation where the debris completely blocks the filter cover or damages the filter cover by collision. The self-cleaning blade is used to clean the gel-like substance, so it is set inside the filter cover. It can push the sticky substance towards the filter cover. At the same time, the self-cleaning blade can also clean the filter cover, reducing the situation where the debris adheres to the filter cover and affects the water pumping.

[0024] Optionally, the mixing blade is provided with a plurality of shark teeth, which are equidistantly spaced along the mixing blade.

[0025] By adopting the above technical solutions, Shark Tooth can cut debris more effectively, further reducing the situation where debris gets tangled on the mixing blade, and further improving the cutting effect.

[0026] In summary, this application has at least the following beneficial effects:

[0027] This application addresses the problem that while existing submersible pumps can smoothly pump water when placed in waters with few impurities and plants, the presence of many impurities and plants in the water source can easily cause blockages, affecting the pump's ability to extract water and potentially damaging the pump. This application solves the problem by using a stirring blade to cut the product below the main body, thereby reducing the entanglement of debris and the blockage of the inlet.

[0028] This application also incorporates multi-stage blades to cut different types of debris in stages, effectively cutting various types of debris and further reducing the impact of different debris on the internal structure. Attached Figure Description

[0038] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] A submersible pump, such as Figure 1 and Figure 2 As shown, the device includes a main body 1, with a water inlet 11 at its bottom and a water outlet 12 on its side wall. An impeller 13 is installed at the water inlet 11, which draws the medium from the water inlet 11 to the water outlet 12. A motor is installed inside the main body 1 to drive the impeller 13, and the motor shaft is fixedly connected to the impeller 13. In practice, when pumping water, the rotation of the impeller 13 draws the medium from the water inlet 11 to the water outlet 12, and the medium is discharged from the water outlet 12 through connecting pipes.

[0040] like Figure 2 and Figure 3 As shown, a stirring blade 2 is also provided at the bottom of the main body 1. The stirring blade 2 is detachably connected to the impeller 13 and can rotate with the impeller 13. The stirring blade 2 extends out of the water inlet 11 of the main body. A guide groove 21 is provided at the bottom of the stirring blade 2 to guide the cut plants. Multiple shark teeth 23 are protruding on the stirring blade 2 and are evenly spaced along the stirring blade 2. In practice, the shark teeth 23 can effectively cut various debris such as plants, limiters, and plastics. The guide groove 21 can guide the water flow and provide a certain guidance for the cut debris, so that the debris can be sent out along the guiding direction, reducing the situation where debris gets tangled on the stirring blade 2 and reducing the situation where debris enters the main body 1 and causes damage.

[0041] like Figure 2 and Figure 4 As shown, a connecting rod 3 is provided on the upper part of the mixing blade 2. The connecting rod 3 is used to fix and connect to the impeller 13. The mixing blade 2 is located at the bottom end of the connecting rod 3. The mixing blades 2 are evenly spaced along the circumference of the connecting rod 3, and all the mixing blades 2 are threadedly connected to the connecting rod 3. In specific implementation, the connecting rod 3 and the impeller 13 are connected by bolts. After connection, the connecting rod 3 can rotate with the impeller 13, and the impeller 13 can drive the connecting rod 3 and the mixing blade 2 to rotate and cut.

[0042] like Figure 2 and Figure 4As shown, the mixing blade 2 is equipped with a connecting rod 3, and an adjusting rod 31 is also provided inside the connecting rod 3. The adjusting rod 31 is rotatably connected to the connecting rod 3. The connecting rod 3 has a relief groove 35 corresponding to the adjusting rod 31. The adjusting rod 31 has an adjusting handle 312 corresponding to the relief groove 35. The adjusting handle 312 is fixedly connected to the adjusting rod 31 and can slide along the relief groove 35. A bevel gear 311 is provided at the bottom of the adjusting rod 31, and each mixing blade 2 is also provided with a corresponding mating gear 22. The bevel gear 311 meshes with the mating gear 22. In specific implementation, the rotation of the adjusting rod 31 can drive each mixing blade 2 to adjust, and a single adjusting rod 31 can simultaneously adjust multiple mixing blades 2 to rotate synchronously, so that the angle of the mixing blades 2 is adjusted synchronously. Mixing blades 2 with the same angle have a better cutting effect.

[0043] like Figure 2 and Figure 4 As shown, a pusher 32 is also fixedly installed on the connecting rod 3. The pusher 32 is used to drive the adjusting handle 312 to slide. A torque sensor 14 is also installed inside the body 1. The torque sensor 14 is electrically connected to the pusher 32. When the torque sensor 14 detects an increase in torque, the pusher 32 pushes the adjusting handle 312 to move. The pusher 32 can be an electric push rod with a waterproof shell. The adjusting handle 312 is adjusted by the electric push rod. At the same time, the torque sensor 14 can detect whether there are any impurities that affect the pumping. Then, by adjusting the angle of the stirring blade 2, the impurities are cut better, further reducing the impact of impurities on the pumping.

[0044] like Figure 2 and Figure 4 As shown, the connecting rod 3 is also equipped with a spiral tungsten blade 33. The spiral tungsten blade 33 is spirally arranged around the connecting rod 3, and multiple spiral tungsten blades 33 are equally spaced around the connecting rod 3. The spiral tungsten blades 33 are fixedly connected to the connecting rod 3 and are located on the lower side of the adjusting handle 312. In specific implementation, the spiral tungsten blades 33 can effectively cut debris after rotation, especially hard debris such as shells and stones, which can reduce the possibility of hard debris entering and causing damage to the main body 1.

[0045] like Figure 2 and Figure 4 As shown, the connecting rod 3 is also equipped with a self-cleaning blade 34, which is positioned between the spiral tungsten blade 33 and the adjusting handle 312. Multiple self-cleaning blades 34 are equidistantly spaced around the connecting rod 3. In practice, the self-cleaning blades 34 are made of acrylic material, capable of cutting and scraping off sticky substances. Acrylic has a certain self-cleaning effect, and sticky substances can easily fall off the self-cleaning blades 34.

[0046] like Figure 2 and Figure 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 encloses the adjusting handle 312. The self-cleaning blade 34 is also provided inside the filter cover 4, while the spiral tungsten blade 33 and the stirring blade 2 are both provided outside the filter cover 4. The self-cleaning blade 34 abuts against the inner wall of the filter cover 4. In specific implementation, the filter cover 4 can more effectively isolate impurities, but at the same time, the spiral tungsten blade 33 and the stirring blade 2 provided on the outside can cut impurities that can cover the filter cover 4, thereby reducing the situation where the filter cover 4 is completely covered and affects water pumping. The self-cleaning blade 34 can clean and scrape off sticky substances and also scrape off impurities on the filter cover 4, thereby reducing the situation where too much impurities adhere to the filter cover 4 and affect water pumping.

[0047] Working principle: The multi-stage blades can effectively cut different types of debris, reducing the impact of debris entering the main body 1 during water pumping. A protective cover is also provided, with some blades placed on the outside to reduce obstruction of the cover, and others placed inside the cover to clean and scrape out debris, further improving stability during use.

[0048] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
