Description

Technical Field

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

[0002] Axial flow pumps operate based on the principle of lift. When the impeller rotates within the pump body, the blades generate an axial thrust on the fluid, causing the fluid to flow along the pump shaft. After entering the impeller, the fluid's pressure and kinetic energy increase under the action of the blades, and then it flows out of the impeller at a higher speed and pressure, being discharged through the pump body's outlet channel.

[0003] Furthermore, the existing Chinese patent CN218439793U discloses an imported self-cleaning submersible axial mixed-flow pump, but this patent has the following shortcomings in actual use:

[0004] Firstly, this patent provides a cleaning component on the surface of the filter screen. Although the filter screen can be cleaned during the operation of the axial flow pump, the cleaning device installed at the inlet of the axial flow pump will reduce the diameter of the inlet, which will greatly affect the flow rate at the inlet of the axial flow pump. At the same time, it cannot clean the impurities stuck on the filter screen. Therefore, this solution proposes a submersible axial flow pump. Utility Model Content

[0005] To address the issues of cleaning components installed at the end of an axial flow pump affecting the pump's flow rate and making it difficult to remove impurities, this application provides a submersible axial flow pump.

[0006] The submersible axial flow pump provided in this application adopts the following technical solution:

[0007] A submersible axial flow pump includes a vertical plate and a support mechanism. Connecting blocks A are symmetrically fixed on the front of the vertical plate. Water supply pipes are welded to the ends of the two connecting blocks A. An arc-shaped cover is fixed at the bottom end of the water supply pipe. The support mechanism includes a base plate. A limiting post is fixed in the middle of the top of the base plate. A cleaning ring is movably inserted through the limiting post. The cleaning ring is movably sleeved with the arc-shaped cover. The cleaning ring and the arc-shaped cover are combined to form a filter cover that can filter impurities.

[0008] By adopting the above technical solution, since the cleaning ring and the arc-shaped cover combine to form a filter cover, impurities in the liquid can be filtered during the liquid transportation process in the water supply pipe, thereby preventing these impurities from entering the inside of the water supply pipe, reducing blockage caused by impurity accumulation inside the water supply pipe, and ensuring the smooth flow of liquid in the water supply pipe. The cleaning ring and the limiting post are movably connected through each other. This structure allows the cleaning ring to move up and down, which facilitates the cleaning of the filter cover, removes impurities attached to it, restores the filter cover to good filtration performance, and extends its service life.

[0009] Preferably, a drive motor is fixedly installed on the upper front of the vertical plate, the output end of the drive motor is fixedly connected to the drive shaft, a positioning column is movably passed through the drive shaft, the positioning column is fixedly passed through the water supply pipe, and an impeller is provided at the end of the drive shaft.

[0010] By adopting the above technical solution, after the drive motor starts, its output end drives the drive shaft to rotate, and the impeller at the end of the drive shaft also rotates. When the impeller rotates, it will generate an axial thrust on the liquid in the water pipe, so that the liquid can flow along the direction of the water pipe.

[0011] Preferably, a fixing block is fixedly connected to the lower back of the vertical plate, a positioning plate is fixedly provided at the bottom of the fixing block, and a lifting ring A is installed at the top of the vertical plate.

[0012] By adopting the above technical solution, the installation of the fixing block and positioning plate can play an auxiliary role in the installation.

[0013] Preferably, a support block is fixedly provided in the middle of the top side of the base plate, and a limiting hole A for movable penetration of the positioning plate is opened in the middle of the top of the support block, and the top of the support block abuts against the bottom of the fixed block.

[0014] By adopting the above technical solution, the support block supports the positioning plate and the fixing block. The existence of the limiting hole A provides a precise installation position for the positioning plate. During the installation process, the positioning plate can be accurately passed through the limiting hole, which helps the various components of the entire device to be assembled according to the design requirements.

[0015] Preferably, a limiting ring is welded above both the top and bottom of the limiting post, an arc-shaped plate is welded to one side of the cleaning ring, and a connecting block B is fixedly connected to the end of the arc-shaped plate.

[0016] By adopting the above technical solution, the cleaning ring can move up and down through the arc plate and connecting block B, thereby achieving the cleaning effect.

[0017] Preferably, the top center of the base plate has a downward sloping surface, and the top four corners of the base plate are fixedly connected with lifting rings B. Limiting holes B are opened at the top four corners of the base plate on one side of the lifting rings B.

[0018] By adopting the above technical solution, the downward sloping surface design at the top center of the base plate is conducive to drainage and cleaning of impurities, and the presence of lifting ring B facilitates the hoisting of the entire device.

[0019] Preferably, an anti-blocking mechanism is provided on one side of the vertical plate. The anti-blocking mechanism includes a side plate, one side of which is fixedly connected to the upper outer side of the vertical plate. A support plate is fixedly provided in the middle of the inner side of the side plate. An electric push rod is fixedly installed in the middle of the top of the support plate. A top plate is fixedly provided at the telescopic end of the electric push rod. A connecting rod that movably passes through the support plate is fixedly provided below one end of the top plate.

[0020] By adopting the above technical solution, the movement of the telescopic end of the electric push rod can drive the top plate to move up and down. Through the movable connection between the connecting rod and the support plate, the stability of the top plate movement is ensured.

[0021] Preferably, a connecting plate is welded to the bottom end of the connecting rod and fixedly installed with the connecting block B.

[0022] By adopting the above technical solution, the installation of connecting block B and connecting plate can be made convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] The conical filter shroud, composed of a cleaning ring and an arc-shaped cover, effectively filters impurities, preventing them from entering the axial flow pump and affecting the normal operation of critical components such as the impeller. Simultaneously, an electric push rod drives the top plate and other components to move the cleaning ring up and down on the limiting post, thus cleaning the conical filter shroud. This not only solves the problem of impurity blockage and maintains the filtration performance of the filter shroud, but also ensures the smooth flow of the axial flow pump's internal channels, stabilizing the pump's operating state. This, in turn, ensures stable flow rate, enabling continuous and efficient operation, extending the pump's service life, reducing downtime maintenance due to unstable flow or blockage, and improving the reliability and stability of the equipment.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] The device's "up, down, left, right" perspectives are... Figure 1 The orientation of the attached diagram is the reference.

[0036] This application discloses a submersible axial flow pump.

[0037] Reference Figure 1 , Figure 5 A submersible axial flow pump includes a vertical plate 1 and a support mechanism 12. Four connecting blocks A2 with symmetrical ends are welded to the front of the vertical plate 1. The ends of the four connecting blocks A2 are welded to the outer peripheral surface of the water supply pipe 3 near the water inlet. A conical arc-shaped cover 4 is fixedly installed at the bottom end of the water supply pipe 3. The outer peripheral surface of the arc-shaped cover 4 has oblique holes. The support mechanism 12 includes a base plate 1201. A limiting post 1204 is fixedly installed in the middle of the top of the base plate 1201 at the inlet of the water supply pipe 3. (The limiting post 1204 is made of two single columns and two limiting rings.) The limiting post 1204 movably passes through the round hole in the middle of the top of the cleaning ring 1205. The cleaning ring 1205 and the oblique hole on the outer peripheral surface of the arc-shaped cover 4 are movably connected. The cleaning ring 1205 and the arc-shaped cover 4 are combined to form a conical filter cover for filtering impurities.

[0038] First, after the device is assembled, the cleaning ring 1205 is installed on the limiting post 1204, and the bottom surface of the cleaning ring 1205 will be attached to the upper end surface of the limiting ring at the bottom of the limiting post 1204. At this time, the cleaning ring 1205 abuts against the bottom of the arc-shaped cover 4, thus forming a conical filter cover that can filter impurities. When impurities accumulate on the surface of the conical filter cover, the cleaning ring 1205 is moved up and down, causing the cleaning ring 1205 to move up and down at the inclined hole on the arc-shaped cover 4, thereby pushing away the impurities at the inclined hole, thus achieving the cleaning effect.

[0039] Reference Figure 2 , Figure 3The front top of the vertical plate 1 is fixedly connected to the mounting base of the drive motor 5 by bolts. The output end of the drive motor 5 is fixedly connected to the vertically downward drive shaft 6. The drive shaft 6 is movably connected to the positioning column 7, which is fixedly connected to the water supply pipe 3. An impeller 8 is fixedly installed at the end of the drive shaft 6. A guide vane is installed above the impeller 8. A flat-bottomed fixing block 9 is fixedly connected to the lower back of the vertical plate 1. A positioning plate 10 with an arc-shaped bottom is fixedly connected to the bottom of the fixing block 9. A lifting ring A101 is fixedly installed at the top of the vertical plate 1. A support block 1202 with a limit hole A1203 in the middle of the top center is fixedly installed on the top side of the bottom plate 1201. The limit hole A1203 movably passes through the positioning plate 10. The top of block 1202 abuts against the bottom of fixed block 9 and the outer side is flush. The top and bottom of the limiting post 1204 are both welded with limiting rings with a diameter larger than the limiting post 1204. The side of the cleaning ring 1205 is welded with an arc plate 1206 with the same side curvature as the outer ring curvature of the cleaning ring 1205. The end of the arc plate 1206 is fixedly connected to a connecting block B1207 with an installation hole on the top surface. The top of the bottom plate 1201 has a downward inclined surface with a five-degree slope in the middle. The top four corners of the bottom plate 1201 are fixedly connected with vertically upward lifting rings B1208. The top four corners of the bottom plate 1201 are provided with limiting holes B1209 that penetrate the bottom plate 1201 on the side of the lifting rings B1208.

[0040] First, pre-embed the studs for connecting the limiting hole B1209 at the preset position. Then, hoist the base plate 1201 to the preset position and install the limiting hole B1209 on the studs. After the base plate 1201 is installed, hoist the vertical plate 1 so that the positioning plate 10 at the bottom of the fixing block 9 on the vertical plate 1 is inserted into the limiting hole A1203 on the support block 1202, thereby installing the vertical plate 1 on the base plate 1201, thereby connecting the arc-shaped cover 4 and the cleaning ring 1205 together, thereby assembling the axial flow pump. By supplying power to the drive motor 5, the impeller 8 is rotated, thereby generating lift at the end of the water pipe 3.

[0041] Reference Figure 1 , Figure 4 An anti-blocking mechanism 11 is provided on one side of the vertical plate 1. The anti-blocking mechanism 11 includes a side plate 1101. One side of the side plate 1101 is fixedly connected to the upper outer side of the vertical plate 1. A support plate 1102 is fixedly provided in the middle of the inner side of the side plate 1101. An electric push rod 1103 is fixedly installed in the middle of the top of the support plate 1102. A top plate 1104 is fixedly provided at the telescopic end of the electric push rod 1103. A connecting rod 1105 that movably passes through the support plate 1102 is fixedly provided below one end of the top plate 1104. A connecting plate 1106 is welded to the bottom end of the connecting rod 1105. The connecting plate 1106 is fixed to the connecting block B1207 by bolts.

[0042] First, install the side plate 1101 on the side of the vertical plate 1, and then install the connecting plate 1106 on the connecting block B1207. By supplying power to the electric push rod 1103, the top plate 1104 and the connecting rod 1105 are driven to rise, thereby driving the connecting plate 1106, the connecting block B1207, and the arc plate 1206 to move up and down, thereby driving the cleaning ring 1205 to move up and down on the limiting post 1204, thereby achieving the function of cleaning the arc cover 4.

[0043] (It should be noted that the electric actuator 1103 and the drive motor 5 are both existing technologies. The connection method of the external control equipment is also existing and mature. Therefore, the specific connection relationship will not be described in detail. Existing connection assemblies can be installed for use.)

[0044] The implementation principle of a submersible axial flow pump in this application embodiment is as follows: by inserting the positioning plate 10 at the bottom of the fixing block 9 on the vertical plate 1 into the limiting hole A1203 on the support block 1202, the vertical plate 1 is installed on the base plate 1201, thereby completing the rapid assembly of the axial flow pump. Power is supplied to the drive motor 5, thereby causing the impeller 8 to rotate, thereby generating lift at the end of the water pipe 3, thus operating the axial flow pump. The cleaning ring 1205 and the arc-shaped cover 4 combine to form a conical filter cover that can filter impurities. Power is supplied to the electric push rod 1103, thereby driving the top plate 1104 and other components to move up and down, thereby driving the cleaning ring 1205 to move up and down on the limiting post 1204, thereby achieving the function of cleaning the conical filter cover.
