Description

Technical Field

[0001] This invention relates to the field of water pump technology, and more specifically to a structure for cleaning entangled debris from the underwater impeller of a mixed-flow pump. Background Technology

[0002] Mixed-flow pumps are a type of large-scale water pump frequently used in water conservancy projects. They combine the characteristics of axial-flow pumps and centrifugal pumps. Mixed-flow pumps are often used for pumping river and lake water. Due to the mature technology of mixed-flow pumps, they can be manufactured in larger sizes and have excellent pumping performance.

[0003] Currently, most large mixed-flow pumps in water conservancy projects sometimes experience the problem of debris entanglement on the impeller during operation. If this is not cleaned in time, it will affect the overall operation of the pump and damage the impeller. Therefore, in order to ensure the service life of the pump, it is often necessary to inspect the impeller of the mixed-flow pump and clean the entangled debris in time before use. However, since the impeller of the mixed-flow pump is generally immersed in water, it is often inconvenient to clean the entangled debris from the impeller.

[0004] Therefore, this application proposes a structure for cleaning entangled material from the underwater impeller of a mixed-flow pump to solve the above-mentioned technical problems. At the same time, the above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a structure for cleaning entangled materials from the impeller of a mixed-flow pump that can directly clean entangled materials underwater.

[0006] The present invention solves the above-mentioned technical problems by adopting the following technical solutions:

[0007] A debris removal structure for an underwater impeller of a mixed-flow pump, installed directly below the impeller assembly of the mixed-flow pump body, includes:

[0008] A mounting base is located directly below the impeller assembly. A vertically oriented limiting shaft is mounted on the mounting base. A sliding sleeve is provided on the outer side of the limiting shaft. A cleaning component for cleaning up debris entangled in the impeller assembly is connected to the sliding sleeve via a movable rod.

[0009] A lever drive assembly is installed on the main body of the mixed flow pump to drive the sliding sleeve to move up and down on the limit shaft.

[0010] Preferably, the lever drive assembly includes a receiving rod disposed below the mixed flow pump body, an electric push rod disposed on the mixed flow pump body for driving the receiving rod to move, a lever structure disposed on the mounting base and hinged at one end to the sliding sleeve, and a connecting slider disposed at the bottom end of the receiving rod and connected to the other end of the lever structure.

[0011] As the receiving rod drives the connecting slider to move in the vertical direction, the lever structure drives the sliding sleeve to move on the limiting shaft.

[0012] Preferably, the lever drive assembly further includes a guide rail disposed on the mounting base for limiting the vertical sliding of the connecting slider.

[0013] Preferably, the movable rod is hinged to the sliding sleeve, and the movable rod is provided with a connecting spring for connecting to the sliding sleeve.

[0014] Preferably, a movable sleeve is rotatably mounted at the end of the movable rod, and an installation sleeve for installing the cleaning component is rotatably fitted inside the movable sleeve.

[0015] Preferably, the end of the movable rod is further fixed with a limiting collar for limiting the rotation range of the movable sleeve at the end of the movable rod.

[0016] Preferably, the cleaning assembly includes a mounting wheel disposed at one end of the mounting sleeve, blades evenly distributed in a ring on the mounting wheel for cutting the entangled material of the impeller assembly, and a cleaning plate located on the blades, wherein the cleaning plate is provided with spikes for moving the entangled material after cutting.

[0017] Preferably, the cleaning assembly further includes a movable plate disposed at the other end of the mounting sleeve, two sets of rubber rollers disposed on the movable plate for rotating and fitting the impeller assembly blades, a roller shaft for limiting the rotation of the two sets of rubber rollers on the movable plate, a transmission shaft disposed inside the mounting sleeve, a bevel gear structure disposed on the roller shaft for driving the transmission shaft to rotate, and a gearbox disposed on the transmission shaft for connecting and driving the mounting wheel to rotate at an accelerated speed.

[0018] Preferably, a rotating movable sleeve is rotatably mounted on the sliding sleeve, the movable rod is hinged to the rotating movable sleeve, and a limiting ring plate is provided at the bottom end of the movable rod to limit the rotation of the rotating movable sleeve on the sliding sleeve. A torsion spring is provided at the bottom end of the limiting ring plate to connect to the limiting shaft rod. The rotating movable sleeve is controlled to rotate on the sliding sleeve by an external driving component.

[0019] Preferably, the external drive component includes a waterproof nylon rope wound and fixed on the rotating movable sleeve and passing through the mixed flow pump body, a rotating wheel set on the mounting base for contacting the waterproof nylon rope, a drive motor set inside the mixed flow pump body, and a take-up wheel set on the drive end of the drive motor for the other end of the waterproof nylon rope to pass through the mixed flow pump body and be wound and fixed.

[0020] This invention provides a structure for cleaning entangled debris from the underwater impeller of a mixed-flow pump. Compared with existing technologies, the advantages of this invention are as follows:

[0021] 1. This invention utilizes a movable sleeve at the end of a movable rod to connect an mounting sleeve for installing a cleaning component. When the movable rod rotates hinged on the sliding sleeve, a connecting spring ensures that the movable plate always drives the rubber roller to remain in contact with the outer surface of the impeller blades of the impeller assembly. Therefore, during the vertical lifting and lowering movement of the sliding sleeve, the rubber roller rotates in contact with the outer surface of the impeller blades. The connection of the roller shaft, bevel gear structure, drive shaft, and gearbox allows the mounting wheel to drive the blades to rotate at high speed to cut the entangled material on the impeller assembly. The cleaning plate with spikes on the blades then removes the cut entangled material from the impeller assembly, thus completing the cleaning of the entangled material on the impeller assembly.

[0022] 2. This invention sets a limiting shaft directly below the impeller assembly, and uses a sliding sleeve on the limiting shaft to set multiple movable rods for installing the cleaning components. Therefore, when cleaning entangled objects, there is no need to disassemble the impeller, avoiding the cumbersome disassembly and installation process of the mixed flow pump. At the same time, it ensures the safety and stability of the equipment, and can directly clean the mixed flow pump impeller underwater, making the operation convenient and fast.

[0023] 3. By setting up a lever drive component, the present invention utilizes the connection between the receiving rod, the connecting slider and the lever structure to drive the sliding sleeve to slide on the limiting shaft simply by the electric push rod installed on the mixed flow pump body. This allows the cleaning component to adhere to the impeller surface of the impeller assembly for cleaning, avoiding damage to the drive components due to prolonged contact with water, and ensuring the safety and stability of the equipment.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the first embodiment, see details below. Figures 1 to 8 .

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the present invention provides a structure for cleaning entangled debris from the underwater impeller of a mixed-flow pump, which is installed directly below the impeller assembly 11 of the mixed-flow pump body 1, and includes:

[0042] Mounting base 3 is located directly below impeller assembly 11. A vertically oriented limiting shaft 31 is mounted on mounting base 3. A sliding sleeve 32 is provided on the outside of the limiting shaft 31. A cleaning component 38 for cleaning up the entanglement of the impeller assembly 11 is connected to the sliding sleeve 32 through multiple movable rods 33.

[0043] The lever drive assembly 2 is installed on the mixed flow pump body 1 to drive the sliding sleeve 32 to move up and down on the limiting shaft 31.

[0044] In practice, the entanglement status of the entangled material on the impeller assembly 11 is first detected by an external detection component, and then the sliding sleeve 32 is driven to move up and down on the limit shaft 31 by the lever drive component 2, so that the cleaning component 38 can contact the impeller assembly 11 to complete the cleaning of the entangled material.

[0045] It should be noted that a corresponding monitoring system, such as a camera or infrared scanner, can be installed inside the limit shaft 31. This system can be used to quickly detect and judge the status of the impeller assembly 11 and determine whether there is any entanglement. When cleaning up entanglement, it can conveniently control the operation of the drive cleaning assembly 38 in real time.

[0046] like Figure 1 As shown, the lever drive assembly 2 includes a receiving rod 22 disposed below the mixed flow pump body 1, an electric push rod 21 disposed on the mixed flow pump body 1 for driving the receiving rod 22 to move, a lever structure 23 disposed on the mounting base 3 and one end of which is hinged to the sliding sleeve 32, and a connecting slider 25 disposed at the bottom end of the receiving rod 22 and connected to the other end of the lever structure 23.

[0047] The connecting lever of the lever structure 23 adopts a telescopic structure (telescopic sleeve assembly or telescopic rod), forming a telescopic lever that exists in the prior art. By setting the lever drive assembly 2, the electric push rod 21 can drive the receiving rod 22 to move in the vertical direction. At this time, while the receiving rod 22 drives the connecting slider 25 to move in the vertical direction, the lever structure 23 drives the sliding sleeve 32 to move in the vertical direction on the limiting shaft 31.

[0048] Therefore, the lever drive assembly 2 can drive the sliding sleeve 32 to slide on the limiting shaft 31 simply by using the electric push rod 21 installed on the mixed flow pump body 1, so that the cleaning assembly 38 can be attached to the impeller surface of the impeller assembly 11 for cleaning, avoiding damage to the drive components due to prolonged contact with water, and ensuring the safety and stability of the equipment.

[0049] It should be noted that the electric actuator 21 mentioned above can be a conventional electric actuator 21 or electric telescopic rod disclosed in the prior art.

[0050] In addition, the lever drive assembly 2 also includes a guide rail 24 disposed on the mounting base 3 for limiting the vertical sliding of the connecting slider 25. The guide rail 24 can directly adopt the waterproof rail structure disclosed in the prior art for limiting the vertical sliding of the connecting slider 25.

[0051] At this time, as Figure 4 As shown, all movable rods 33 are hinged to sliding sleeves 32, and a connecting spring 34 for connecting the movable rods 33 to the sliding sleeves 32 is provided on the movable rods 33.

[0052] During the vertical sliding process of the sliding sleeve 32, a limiting shaft 31 is set directly below the impeller assembly 11. Multiple movable rods 33 for installing the cleaning assembly 38 are set on the sliding sleeve 32 that slides on the limiting shaft 31. Therefore, it is not necessary to disassemble the impeller when cleaning the entangled material, avoiding the cumbersome disassembly and installation process of the mixed flow pump. At the same time, it ensures the safety and stability of the equipment and can directly clean the impeller of the mixed flow pump underwater. The operation is convenient and fast.

[0053] At this time, the connecting spring 34 can cooperate with the movable rod 33 to rotate on the sliding sleeve 32 to ensure that the cleaning component 38 is always located on the impeller blade surface of the impeller assembly 11 to complete the cleaning.

[0054] like Figure 5 , Figure 6 and Figure 7 As shown, a movable sleeve 35 is rotatably mounted at the end of the movable rod 33, and an installation sleeve 36 for installing the cleaning component 38 is rotatably fitted inside the movable sleeve 35.

[0055] The movable rod 33 is also fixed with a limiting collar 37 at the end of the movable rod 33 to limit the rotation range of the movable sleeve 35 at the end of the movable rod 33, which can limit the movable sleeve 35 to drive the cleaning assembly 38 to rotate.

[0056] like Figure 5 , Figure 6 and Figure 7 As shown, the cleaning assembly 38 includes a mounting wheel 381 disposed at one end of the mounting sleeve 36, blades 382 evenly distributed in an annular pattern on the mounting wheel 381 for cutting the entangled material of the impeller assembly 11, and a cleaning plate 383 located on the blades 382. The cleaning plate 383 is provided with spikes 3831 for driving the entangled material after cutting to move.

[0057] In practice, when the cleaning component 38 is located on the surface of the impeller blades of the impeller assembly 11, the rotating wheel 381 drives the blade fan 382 to rotate and cut the entangled material on the impeller assembly 11. Then, the cleaning plate 383 with spikes 3831 on the blade fan 382 can drive the cut entangled material to detach from the impeller assembly 11, thereby completing the cleaning of the entangled material on the impeller assembly 11.

[0058] It should be noted that the sharp end of the blade fan 382 is a blunt-angled blade made of stainless steel, and the spike 3831 is composed of multiple stainless steel spikes.

[0059] In addition, such as Figure 7 and Figure 8 As shown, the cleaning assembly 38 also includes a movable plate 384 disposed at the other end of the mounting sleeve 36, two sets of rubber rollers 385 disposed on the movable plate 384 for rotating and fitting the blades of the impeller assembly 11, a roller shaft 386 for limiting the rotation of the two sets of rubber rollers 385 on the movable plate 384, a drive shaft 388 rotatably disposed inside the mounting sleeve 36, a bevel gear structure 387 disposed on the roller shaft 386 for driving the drive shaft 388 to rotate, and a gearbox 389 disposed on the drive shaft 388 for connecting and driving the mounting wheel 381 to rotate at an accelerated speed.

[0060] In specific implementation, by using the movable sleeve 35 at the end of the movable rod 33 to connect the mounting sleeve 36 for installing the cleaning component 38, when the movable rod 33 is hinged and rotated on the sliding sleeve 32, the connecting spring 34 can keep the movable plate 384 driving the rubber roller 385 to adhere to the outer surface of the impeller blade of the impeller assembly 11. Therefore, during the vertical lifting and lowering movement of the sliding sleeve 32, the rubber roller 385 will rub against the outer surface of the impeller blade of the impeller assembly 11 and rotate. At this time, the roller shaft 386, the bevel gear structure 387, the transmission shaft 388 and the gearbox 389 are connected to each other, which allows the mounting wheel 381 to drive the blade fan blade 382 to rotate at high speed.

[0061] It should be noted that the bevel gear structure 387 and gearbox 389 mentioned above are both existing technologies. Their basic principles and structures will not be elaborated here. The bevel gear structure 387 and gearbox 389 disclosed in the existing technology can be used directly.

[0062] A second embodiment is proposed based on the above embodiments, for details please refer to [link / reference needed]. Figure 9 and Figure 10 .

[0063] A structure for cleaning entangled material from an underwater impeller of a mixed-flow pump differs from the first embodiment described above in that: a cleaning component 38 for cleaning entangled material from the impeller assembly 11 is connected to a sliding sleeve 32 via a single movable rod 33. At this time, a rotating movable sleeve 39 rotates on the sliding sleeve 32, and the movable rod 33 is hinged to the rotating movable sleeve 39. A limiting ring plate 391 is provided at the bottom end of the movable rod 33 to limit the rotation of the rotating movable sleeve 39 on the sliding sleeve 32. A torsion spring 393 is provided at the bottom end of the limiting ring plate 391 to connect to the limiting shaft 31. The rotating movable sleeve 39 is controlled to rotate on the sliding sleeve 32 by an external driving component.

[0064] The external drive components include a waterproof nylon rope 392 that is wound and fixed on the rotating movable sleeve 39 and passes through the mixed flow pump body 1, a rotating wheel 394 that is set on the mounting base 3 for contacting the waterproof nylon rope 392, a drive motor 396 that is set inside the mixed flow pump body 1, and a take-up wheel 395 that is set on the drive end of the drive motor 396 for the other end of the waterproof nylon rope 392 to pass through the mixed flow pump body 1 and be wound and fixed.

[0065] In use, an upward-facing infrared monitoring camera can be installed at the top of the limiting shaft 31. At this time, the drive motor 396 controls the winding wheel 395 to rotate. The waterproof nylon rope 392, in conjunction with the rotating wheel 39, changes direction, allowing the waterproof nylon rope 392 and the torsion spring 393 to make the rotating sleeve 39 rotate in any direction on the sliding sleeve 32. In conjunction with the lever drive component 2, the cleaning component 38 is made to adhere to the impeller surface of the impeller assembly 11 for cleaning. This method is applicable to different parts of the impeller surface of the impeller assembly 11 for precise point cleaning and is convenient to use.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0067] Furthermore, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of the present invention, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0068] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
