Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and specifically relates to a novel submersible pump. Background Technology

[0002] A submersible pump is a drainage device that integrates an electric motor and a water pump into one unit, allowing it to operate while submerged in liquid. Its core feature is its sealing technology, which prevents liquid from seeping into the motor. During operation, the high-speed rotating impeller generates centrifugal force, drawing liquid in from the bottom and pressurizing it for discharge along the pipeline. It is widely used in deep well water extraction, foundation pit drainage, agricultural irrigation, sewage treatment, and industrial circulation systems.

[0003] To prevent impeller damage and flow channel blockage, submersible pumps typically have a filter screen installed at the inlet to intercept foreign objects. However, after prolonged use, the fixed filter screen can become clogged, making it difficult for the pump to receive water and thus affecting its dry running. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel submersible pump that prevents impeller idling due to mesh blockage.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel submersible pump, characterized in that it includes a pump body, a filter base is provided at the bottom of the pump body, the filter base is provided with a plurality of flow holes, a plurality of threaded guide protrusions are provided on the side wall of the filter base, and a filter ring mesh is movably connected to the side wall of the filter base, a plurality of threaded guide grooves are provided on the inner wall of the filter ring mesh, a float ring is provided outside the pump body, and a connecting rope is provided between the float ring and the filter ring mesh.

[0006] In the aforementioned novel submersible pump, the bottom of the filter base is provided with a support tray, and the pump body is provided with several limiting protrusions.

[0007] In the aforementioned novel submersible pump, the limiting protrusion is provided with a rotating shaft, and the rotating shaft is provided with a torsion spring.

[0008] In the aforementioned novel submersible pump, the top of the float ring is provided with several handles.

[0009] Compared with existing technologies, this new submersible pump features a sliding filter ring on the filter base. The movement of the filter ring is controlled by a float ring, and the filter ring moves at an angle with the help of threaded guide protrusions. The angled movement makes better use of the effective area of ​​the filter ring compared to the linear movement. The limiting protrusion is connected by a rotating shaft and supported by a torsion spring, which can prevent the filter ring from moving too high and causing filtration failure. The bendable design makes the filter ring easier to disassemble, clean, and store. The downward bending limiting protrusion also facilitates the installation of the filter ring.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2 As shown in Figures 3 and 4, this novel submersible pump includes a pump body 2, a filter base 5 at the bottom of the pump body 2, several flow holes 9 on the filter base 5, several threaded guide protrusions 8 on the side wall of the filter base 5, and a filter ring 6 movably connected to the side wall of the filter base 5. Several threaded guide grooves 10 are provided on the inner wall of the filter ring 6. A float ring 1 is provided outside the pump body 2, and a connecting rope 3 is provided between the float ring 1 and the filter ring 6. When in use, the pump is submerged in water, the float ring 1 causes the filter ring 6 to float, and the bottom of the filter ring 6 participates in filtration. As the pump continues to work and the water level decreases, the float ring 1 descends, and the filter ring 6 also descends, with the remaining part of the filter ring 6 participating in filtration and interception. The filter ring 6 rotates and descends, which can make fuller use of the effective area of ​​the filter ring 6.

[0017] Preferably, the bottom of the filter base 5 is provided with a support tray 7, and the water pump body 2 is provided with several limiting protrusions 4. The limiting protrusions 4 prevent the filter ring network 6 from failing when the water level is too high.

[0018] Preferably, the limiting protrusion 4 is provided with a rotating shaft 13, and the rotating shaft 13 is provided with a torsion spring 12. The downward folding limiting protrusion 4 can facilitate the installation of the filter ring 6, and at the same time, it can be manually bent to make the disassembly of the filter ring 6 easier.

[0019] Preferably, the top of the float ring 1 is provided with several handles 11.

[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0021] Although this document frequently uses terms such as float ring 1, pump body 2, connecting rope 3, limiting protrusion 4, filter base 5, filter ring 6, support tray 7, threaded guide protrusion 8, flow hole 9, threaded guide groove 10, handle 11, torsion spring 12, and rotating shaft 13, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
