Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, specifically a power-driven axial flow flexible shaft 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 for fountain landscaping. Because the curvature of the lower surface of the pump blades is greater than that of the upper surface, and the water flows primarily axially across the impeller, this type of pump is usually called an axial-flow pump. Flexible shaft pumps have a unique structure and are extremely small in size, with a pump head diameter of only 2.4 or 2.8 cm and a main body length of approximately 45 cm. They can be directly inserted into various small-diameter plastic well pipes and can be submerged to depths of 10, 50, 100 meters, or even deeper, depending on the length of the plastic pipe. They combine the advantages of self-priming pumps and submersible pumps, overcoming many drawbacks of hand pumps, jacking pumps, self-priming pumps, and submersible pumps. They possess both head and suction lift capabilities, thus filling a functional gap in the performance of submersible flexible shaft pumps in my country.

[0003] Since a tall support needs to be installed at the bottom of the pump body after the flexible shaft pump is combined with the submersible pump, the existing solutions mostly use welding tools to weld the pump body and the support directly to fix them together and increase the overall connection strength and stability after splicing. However, the welded pump body and support cannot be disassembled, which is inconvenient for workers to transport and store, and also inconvenient for workers to use. Utility Model Content

[0004] The purpose of this invention is to provide a power-driven rear-mounted axial flow flexible shaft submersible pump to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power-driven axial flow flexible shaft submersible pump, including a submersible pump body, a connecting pipe fixedly connected to the bottom of the submersible pump body, a support mechanism provided at the bottom of the submersible pump body, and a fixing mechanism provided inside the support mechanism.

[0006] The support mechanism includes an installation component, a support component, and a snap-fit ​​component. The installation component is located at the bottom of the submersible pump body, the support component is located at the bottom of the installation component, and the snap-fit ​​component is located on the outer ring of the submersible pump body.

[0007] The fixing mechanism includes a socket component and a fixing component. The socket component is disposed within the snap-fit ​​component, and the fixing component is disposed at the bottom of the mounting component.

[0008] Preferably, the mounting assembly includes a support plate, which is disposed at the bottom of the submersible pump body. A retaining frame is fixedly connected to the top of the support plate, and the retaining frame is engaged with the bottom of the submersible pump body. A retaining groove is provided at the bottom of the submersible pump body corresponding to the position of the retaining frame.

[0009] Preferably, the support assembly includes a support leg, which is fixedly connected to the bottom of the support plate, a floor mat is fixedly connected to the bottom of the support leg, and a reinforcing rod is fixedly connected to the outer ring of the support leg.

[0010] Preferably, the snap-fit ​​assembly includes a convex ring, which is fixedly connected to the bottom of the outer ring of the submersible pump body. The bottom of the convex ring is in contact with the top of the support plate. A convex plate is fixedly connected to the outside of the convex ring, and a positioning clip tube is fixedly connected to the bottom of the convex plate. The positioning clip tube is snapped into the support plate.

[0011] Preferably, the sleeve assembly includes a limiting ring, which is fixedly connected to the top of the protrusion plate, and a bolt is provided on the inner ring of the limiting ring, which is sleeved on the inner ring of the positioning clamp tube.

[0012] Preferably, the fixing component includes a threaded cylinder, which is threadedly connected to the outer ring of the bolt, and a fixing arm is fixedly connected to the outer ring of the threaded cylinder, which is fixedly connected to the bottom of the support plate.

[0013] Compared with the prior art, this utility model provides a power-driven axial flow flexible shaft submersible pump, which has the following advantages:

[0014] 1. This rear-mounted axial flow flexible shaft submersible pump uses a support mechanism to position the pump body by engaging a retaining frame within a slot. This increases the stability of the pump body after it is placed on top of the support plate. Simultaneously, the positioning clamp is engaged within the support plate, enhancing the connection strength between the pump body and the support plate. This further increases the stability of the pump body after installation, improves overall stability during subsequent use, and reduces vibration during operation.

[0015] 2. This rear-mounted axial flow flexible shaft submersible pump, through a fixed mechanism, uses bolts fitted into the inner ring of the positioning clamp tube and threaded into the threaded cylinder to fix the positioning clamp tube and the support plate. This ensures that the submersible pump body will not detach from the support plate after being placed on top, increasing the stability of the submersible pump body when placed on top of the support plate. The detachable submersible pump body and support plate allow operators to quickly install or disassemble them as needed, facilitating the transportation and storage of the entire device and making it convenient for operators to use.

[0025] This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figures 1 to 5 A power-driven axial flow flexible shaft submersible pump includes a submersible pump body 3, a connecting pipe 31 fixedly connected to the bottom of the submersible pump body 3, a support mechanism 1 provided at the bottom of the submersible pump body 3, and a fixing mechanism 2 provided inside the support mechanism 1.

[0028] The support mechanism 1 includes an installation component 11, a support component 12, and a snap-fit ​​component 13. The installation component 11 is located at the bottom of the submersible pump body 3, the support component 12 is located at the bottom of the installation component 11, and the snap-fit ​​component 13 is located on the outer ring of the submersible pump body 3.

[0029] Mounting assembly 11 includes a support plate 1101, which is disposed at the bottom of the submersible pump body 3. A retaining frame 1102 is fixedly connected to the top of the support plate 1101 and is snapped into the bottom of the submersible pump body 3. A retaining groove 1103 is provided at the bottom of the submersible pump body 3 corresponding to the position of the retaining frame 1102. Support assembly 12 includes a support leg 1201, which is fixedly connected to the bottom of the support plate 1101. The bottom of the support leg 1201 is fixedly connected to... A floor mat 1202 is attached, and a reinforcing rod 1203 is fixedly connected to the outer ring of the support leg 1201. The snap-fit ​​assembly 13 includes a convex ring 1301, which is fixedly connected to the bottom of the outer ring of the submersible pump body 3. The bottom of the convex ring 1301 is in contact with the top of the support plate 1101. A convex plate 1302 is fixedly connected to the outside of the convex ring 1301. A positioning clip tube 1303 is fixedly connected to the bottom of the convex plate 1302 and snaps into the support plate 1101.

[0030] Furthermore, the clip frame 1102 engages with the clip slot 1103 to position the submersible pump body 3, increasing the stability of the submersible pump body 3 after it is placed on top of the support plate 1101. At the same time, the positioning clip tube 1303 engages with the support plate 1101, improving the connection strength between the submersible pump body 3 and the support plate 1101, further increasing the stability of the submersible pump body 3 after installation, increasing the overall stability of the submersible pump body 3 during subsequent use, and reducing the vibration of the submersible pump body 3 during use.

[0031] Example 2

[0032] See Figures 1 to 5 Furthermore, based on Embodiment 1, the fixing mechanism 2 includes a sleeve component 21 and a fixing component 22. The sleeve component 21 is disposed within the snap-fit ​​component 13, and the fixing component 22 is disposed at the bottom of the mounting component 11.

[0033] The sleeve assembly 21 includes a limiting ring 2101, which is fixedly connected to the top of the protrusion plate 1302. A bolt 2102 is provided on the inner ring of the limiting ring 2101, and the bolt 2102 is sleeved on the inner ring of the positioning clamp tube 1303. The fixing assembly 22 includes a threaded cylinder 2201, which is threadedly connected to the outer ring of the bolt 2102. A fixing arm 2202 is fixedly connected to the outer ring of the threaded cylinder 2201, and the fixing arm 2202 is fixedly connected to the bottom of the support plate 1101.

[0034] Furthermore, the bolt 2102, which is fitted into the inner ring of the positioning clamp tube 1303, is simultaneously threaded into the threaded cylinder 2201, thus fixing the positioning clamp tube 1303 and the support plate 1101. This ensures that the submersible pump body 3 will not detach from the support plate 1101 after being placed on top of it, increasing the stability of the submersible pump body 3 when placed on top of the support plate 1101. The detachable submersible pump body 3 and support plate 1101 allow workers to quickly install or disassemble them as needed, facilitating the transportation and storage of the entire device and making it convenient for workers to use.

[0035] In actual operation, when this device is used and the submersible pump body 3 needs to be installed, the operator first places the submersible pump body 3 on top of the support plate 1101, so that the clip frame 1102 is engaged with the bottom of the submersible pump body 3 through the clip groove 1103. At the same time, the positioning clip tube 1303 is engaged with the support plate 1101 so that the bottom of the protruding plate 1302 of the protruding ring 1301 is in contact with the top of the support plate 1101. Then the operator puts the bolt 2102 into the inner ring of the positioning clip tube 1303 and moves it downward so that the bolt 2102 contacts the threaded cylinder 2201. Then the operator rotates the bolt 2102, and the bolt 2102 rotates into the inner ring of the threaded cylinder 2201 and moves downward until the bolt 2102 can no longer move downward. At this time, the fixing work of the submersible pump body 3 is completed.
