Description

Technical Field

[0001] This utility model relates to water pumps, and more particularly to an integrated water pump connection structure. Background Technology

[0002] Axial flow pumps are widely used in farmland irrigation, urban drainage, and aquaculture due to their advantages such as large flow rate, high efficiency, and compact structure. However, in practical applications, especially in water bodies containing impurities such as silt, dead leaves, and aquatic plants, the pump's inlet is easily clogged, or impurities entering the pump body can cause impeller wear, thus affecting its normal operating efficiency and service life. Therefore, designing an axial flow pump with good filtration and stable support performance has become an urgent problem to be solved in the industry.

[0003] Currently, existing technical solutions attempt to address this problem. For example, Chinese Patent Publication No. CN219412953U discloses an axial-flow permanent magnet motor water pump, whose structure includes multiple components such as an inlet bell mouth, a flange plate, a stainless steel mesh cylinder, a fixed bracket, a fixed base plate, a support cover, a plastic float plate, a rubber baffle, and a groove. The flange plate is located below the inlet bell mouth, and the stainless steel mesh cylinder is positioned between the flange plate and the fixed base plate for filtering the incoming water. Simultaneously, the water pump utilizes the plastic float plate and support cover to provide stable support and prevent the bottom of the pump from sinking into silt.

[0004] However, the aforementioned existing technical solutions still have some shortcomings. Their protective filtration mechanism consists of multiple separate components, including flange plates, stainless steel mesh cylinders, fixed supports, fixed base plates, support covers, plastic floats, rubber baffles, and slots, resulting in a complex structure and a large number of parts. Furthermore, during manufacturing, this solution typically requires assembling multiple components such as flange plates, fixed supports, fixed base plates, and reinforcing ribs through welding. This separate design and welding connection method not only increases the complexity and cost of the production process but also easily leads to stress concentration at the joints under long-term use and vibration environments, resulting in insufficient structural stability and strength of the entire protective filtration mechanism, thus affecting the overall performance and reliability of the water pump. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an integrated water pump connection structure to improve structural stability and strength.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an integrated water pump connection structure, including a motor, a support base, an impeller, and a guide vane assembly. The motor is connected to the support base, and a pump shaft is rotatably connected inside the support base. The motor drives the impeller to rotate through the pump shaft. The guide vane assembly is connected to the support base, and the impeller is located between the guide vane assembly and the pump shaft. The support base includes an integrated first flange, a second flange, a third flange, a support cylinder, a support ring, and a reinforcing plate. The support ring is fixed to the inner wall of the support cylinder and is coaxially arranged. The first flange and the second flange are located at opposite ends of the support cylinder. The motor abuts against the support ring and is fixed to the second flange. The third flange is used to connect to the guide vane assembly. The reinforcing plate is located outside the support cylinder. The upper end of the reinforcing plate is connected to the third flange, the side wall of the reinforcing plate is connected to the outer wall of the support cylinder, and the lower end of the reinforcing plate is connected to the second flange. The outer wall of the first flange is integrally connected to the side wall of the reinforcing plate.

[0007] To achieve the above technical solution, the support base integrates the first flange, second flange, third flange, support cylinder, support ring, and reinforcing plate into a single, integral core load-bearing structure. Key components such as the motor and guide vane assembly are rigidly connected to this support base. In particular, the external reinforcing plate connects the second and third flanges at both ends of the support cylinder into a single unit, and the connection rigidity is further strengthened through the first flange. This eliminates the stress concentration and structural weaknesses caused by traditional separate welding, significantly improving the overall strength, rigidity, and vibration resistance of the entire pump connection structure, ensuring long-term operational stability and reliability, and significantly simplifying the manufacturing process.

[0008] As a preferred embodiment of this utility model, a reinforcing ring is provided on the side of the third flange facing the first flange. The upper edge of the reinforcing ring is integrally connected to the inner wall of the third flange. The inner diameter of the reinforcing ring gradually increases from the first flange toward the direction closer to the third flange. The impeller is located inside the reinforcing ring and is adapted to the reinforcing ring. The reinforcing ring, the third flange, and the support cylinder are coaxially arranged. The outer wall of the reinforcing ring is integrally connected to the reinforcing plate.

[0009] To achieve the above technical solution, the reinforced ring serves two main purposes. First, it directly strengthens the third flange in the impeller's working area, effectively resisting the radial force generated by fluid dynamic pressure and ensuring the stability of the impeller-pump body clearance. Second, its tapered design, with its inner diameter gradually increasing from the first flange towards the third flange, effectively guides and stabilizes the high-pressure fluid discharged from the impeller, allowing the fluid to smoothly enter the subsequent guide vane assembly, reducing hydraulic losses and turbulence, thereby improving the pump's operating efficiency and stability. Simultaneously, the integrated connection between the reinforced ring's outer wall and the reinforcing plate further enhances the structural rigidity of this critical component.

[0010] As a preferred embodiment of this utility model, a water guide ring is provided on the side of the reinforcing ring away from the third flange, and a receiving groove is provided on the side wall of the reinforcing plate. The upper edge of the water guide ring is integrally connected to the side of the reinforcing ring away from the third flange, the outer wall of the water guide ring is integrally connected to the side wall of the receiving groove, and the lower edge of the water guide ring is integrally connected to the bottom wall of the receiving groove. The water guide ring and the reinforcing ring are coaxially arranged.

[0011] To achieve the above technical solution, the fluid first flows through the guide ring before entering the reinforcing ring. The guide ring pre-regulates and guides the fluid about to enter the impeller's working area, effectively improving the inlet flow pattern, reducing fluid pre-swirl and turbulence, and creating more favorable conditions for the impeller's efficient and stable operation. By integrating the guide ring with the reinforcing ring and the receiving groove on the reinforcing plate, not only is precise geometric positioning achieved, ensuring the guiding effect, but the structure of the guide ring also further strengthens the structural strength and integrity of the entire inlet assembly, improving the overall performance of the pump.

[0012] As a preferred embodiment of this utility model, a connecting flange is provided on the outside of the second flange, and a reinforcing section is provided between the connecting flange and the second flange. One end of the reinforcing section is integrally connected to the outer wall of the second flange, and the other end of the reinforcing section is integrally connected to the inner wall of the connecting flange. The lower end of the reinforcing plate is integrally connected to the side wall of the reinforcing section and the side wall of the connecting flange.

[0013] To achieve the above technical solution, a connecting flange provides the water pump with a connection interface to external pipelines or the mounting base. The reinforcing section, acting as a transition structure between the second flange and the connecting flange, ensures the rigidity of the connection and avoids structural weaknesses caused by external connections. Simultaneously, the lower end of the reinforcing plate is integrally connected to the side wall of the reinforcing section and the connecting flange, effectively transferring and distributing the load from the external connection across the entire integrated support structure. This design provides a convenient and reliable external installation interface while maintaining and enhancing the structural stability and load-bearing capacity of the entire pump body base.

[0014] In a preferred embodiment of this utility model, the reinforcing plate has a first groove on the side facing the first flange, and the first flange has a first mounting hole corresponding to the first groove. The reinforcing plate has a second groove on the side facing the second flange, and the second flange has a second mounting hole corresponding to the second groove.

[0015] To achieve the above technical solution, the first and second grooves on the reinforcing plate correspond precisely to the first and second mounting holes on the first and second flanges. When the motor is fixed to the second flange with bolts, the bolts can be threaded into the second mounting hole and inserted into the second groove. When the sleeve is fixed to the first flange with bolts, the bolts are threaded into the first mounting hole and inserted into the first groove, and the pump shaft is located in the sleeve.

[0016] As a preferred embodiment of this utility model, the reinforcing plate is provided with weight reduction holes, and the plurality of reinforcing plates are evenly distributed along the axis of the support cylinder.

[0017] To achieve the above technical solution, multiple reinforcing plates are evenly distributed along the axis of the support cylinder, jointly bearing and distributing the load from motor operation and water flow impact. The technical effects are as follows: First, the even distribution of multiple reinforcing plates ensures balanced reinforcement of the support cylinder in all radial directions, making the overall structure more uniformly stressed and effectively preventing excessive stress at single points or unbalanced vibration, thus enhancing operational stability. Second, weight-reduction holes are provided on each reinforcing plate, effectively removing redundant material while maintaining the core structural strength required for its role as a support rib. This significantly reduces the weight of the entire support base, thereby saving manufacturing costs and facilitating transportation and installation.

[0018] In a preferred embodiment of this utility model, a protective frame is connected to the side of the connecting flange facing away from the reinforcing plate, and the motor is located inside the protective frame.

[0019] The above technical solution involves encasing the motor in a protective frame. The effect is that the protective frame provides effective physical protection for the motor, resisting accidental impacts from the external environment. Attached Figure Description
