Description

Technical Field

[0001] This invention relates to the field of water pump fault detection technology, specifically to a component wear detection mechanism for water pump faults. Background Technology

[0002] During long-term operation, key components of a water pump, such as the impeller, bearings, and shaft seals, are prone to wear due to friction, corrosion, and aging. If the wear is not detected and addressed in time, it can lead to a decrease in pump efficiency and an increase in energy consumption, or even equipment failure and shutdown, or even serious safety accidents.

[0003] Existing technology 1 (Chinese patent with announcement number CN220649401U and announcement date of 2024-03-22) discloses a concentricity detection fixture for a water pump impeller and shaft. The fixture includes a concentricity detection fixture body. A water pump shaft is set in a detection frame on the concentricity detection fixture body, and a water pump impeller and impeller hub are fixedly installed on the water pump shaft. Two sets of mounting slots are respectively opened on the side wall of the detection frame, and a first laser rangefinder and a second laser rangefinder are respectively fixedly engaged inside the two sets of mounting slots. By illuminating different positions on the outside of the impeller hub with the laser rangefinders, different distance values ​​are obtained. If the different distance values ​​are the same, it indicates that the water pump shaft and impeller are concentrically set; otherwise, the water pump shaft and impeller are eccentrically set. This detection method has the advantages of being convenient, fast, and efficient.

[0004] There is also a prior art (Chinese patent with publication number CN121140608A and publication date of 2025-12-16) of a laser dimension inspection device for the production of water pump accessories, which includes a dimension inspection device. The dimension inspection device is equipped with a conveying device that assembles multiple impeller bodies. Through the electric push rod and the air pump, and with the cooperation of the laser inspection component and the angle self-adjustment component, the suction force of the air pump can make the two suction cup bodies, which are separate from the blades, stick tightly to the blades. Then, under the suction force of the suction cups, the rubber ring fixed to the reset slide cylinder sticks tightly to the blades, achieving the function of automatically adapting to blades with different torsion angles. Traditional inspection methods require manual adjustment of equipment, replacement of fixtures, or multiple measurements to obtain complete data when facing blades with different torsion angles. These operations are not only time-consuming and labor-intensive, but also prone to measurement errors due to human factors. The laser dimension inspection device automatically adapts to different torsion angles.

[0005] During the testing of water pumps, impurities such as oil, dust, and metal shavings may accumulate on the surface of the pump during long-term use or storage. If laser testing is performed directly, these impurities will interfere with the reflection and reception of the laser signal, leading to deviations in the test data and affecting the accurate judgment of the wear degree of the components. Traditional testing institutions often use single-dimensional testing methods, which are difficult to fully reflect the radial and axial wear of water pump components, and may miss key wear information, failing to provide sufficient basis for subsequent repair or replacement.

[0006] Therefore, we propose a component wear detection mechanism for water pump failures to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a component wear detection mechanism for water pump failure, in order to solve the problem mentioned in the background art that, in the current market, during the testing of water pumps, impurities such as oil, dust, and metal shavings may adhere to the surface of the water pump during long-term use or storage. If laser testing is performed directly, these impurities will interfere with the reflection and reception of the laser signal, resulting in deviations in the test data and affecting the accurate judgment of the wear degree of the components.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a component wear detection mechanism for water pump failure, comprising a housing, an internal placement rack for placing the water pump to be tested, a drive assembly on the housing, and two sets of laser detectors on the drive assembly, which perform the testing operation on the water pump through the two sets of laser detectors. A fixing frame is fixedly connected to the side of the placement rack, and a cleaning mechanism is provided on the fixing frame. The cleaning mechanism cleans impurities on the surface of the water pump to be tested by changing the position of the laser detectors, thereby avoiding interference from impurities to subsequent testing.

[0009] Preferably, the drive assembly includes a limiting frame, which is fixedly connected to the upper surface of the equipment housing. The upper surface of the equipment housing is provided with front and rear drive components, and the output side of the front and rear drive components is provided with front and rear mounting plates. The front and rear mounting plates are slidably connected to the upper surface of the limiting frame, thereby limiting the front and rear mounting plates.

[0010] Preferably, the upper surface of the front and rear mounting plates is provided with a transverse driving component, and the output side of the transverse driving component is provided with a transverse mounting plate. The front side of the front and rear mounting plates is also fixedly connected with a limiting frame, and the transverse mounting plate and the limiting frame provided on the front side of the front and rear mounting plates are slidably connected.

[0011] Preferably, the laser detector is fixedly connected to the front side of the horizontal mounting plate, and the output ends of the two sets of laser detectors are set accordingly. The two sets of laser detectors are located on the upper and lower sides of the mounting frame, respectively, so that the wear condition of the components can be scanned and detected from both the radial and axial dimensions of the water pump.

[0012] Preferably, an auxiliary plate is fixedly connected to the lower inner side of the placement rack, and a soft pad is fixedly connected to the upper surface of the auxiliary plate. The water pump to be processed is placed on the upper surface of the soft pad. The soft pad provides cushioning and protection for the bottom of the water pump, preventing the water pump from being damaged by collision during placement or testing.

[0013] Preferably, the cleaning mechanism includes an air supply box, which is fixedly connected to a horizontal mounting plate. A sealing plate is slidably connected inside the air supply box, and the side of the sealing plate is in contact with the inner wall of the air supply box. A connecting rod is fixedly connected to one side of the sealing plate, and a spring is fixedly connected between the side of the sealing plate and the inner wall of the air supply box.

[0014] Preferably, the connecting rod is slidably connected to the side of the air supply box, and the outer end of the connecting rod is fixedly connected to a mounting bracket, and a roller is rotatably connected to the mounting bracket. A contact bracket is fixedly connected to the side of the fixed bracket, and the contact bracket is arranged in a zigzag structure. The outer side of the roller is in contact with the outer side of the contact bracket.

[0015] Preferably, a rotating shaft is rotatably connected to the fixed frame, and a cleaning pipe is fixedly connected to the upper end of the rotating shaft, and a connecting hose is connected through the upper end of the cleaning pipe and the air supply box.

[0016] Preferably, the fixed frame has a through groove, the lower end of the rotating shaft extends into the through groove, and swing plates are fixedly connected to the left and right sides of the rotating shaft. A swing magnet is fixedly connected to the outer end of the swing plate. The swing magnet is located corresponding to the outward protrusion side of the contact frame. A fixed magnetic ring is fixedly connected to the outer side of the roller, and the magnetic properties of the fixed magnetic ring are opposite to those of the swing magnet.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) Two sets of laser detectors are set up. When the water pump is tested, the front and rear drive components can drive the front and rear mounting plates to move smoothly along the limit frame in the front and rear direction, while the lateral drive components can drive the lateral mounting plate to slide laterally along the limit frame on the front side of the front and rear mounting plates. This drives the two sets of laser detectors to perform two-dimensional movements in the front and rear and laterally at the same time, so that the laser detectors can perform a full-coverage scanning test on the water pump placed on the soft pad of the placement rack. Since the two sets of laser detectors are located on the upper and lower sides of the water pump and the output ends are set accordingly, the laser beams emitted by them can act on the surface of the water pump components from the radial and axial dimensions of the water pump at the same time. Through this multi-dimensional scanning test, a complete three-dimensional data model of the wear condition of the water pump components can be constructed, providing accurate quantitative basis for subsequent fault analysis and life assessment. (2) When the front and rear mounting plates move closer to the side of the placement frame, the outer side of the roller will contact the outer surface of the contact frame simultaneously. As the horizontal mounting plate moves laterally, the roller will roll along the zigzag outer contour of the contact frame. When the roller rolls to the side of the contact frame that protrudes outward, the contact frame will apply a thrust to the connecting rod through the roller and the mounting frame into the air supply box. At this time, the compressed air in the air supply box will be delivered to the cleaning pipe through the connecting hose and sprayed out from the nozzle of the cleaning pipe, forming a directional airflow that directly acts on the surface of the water pump to be tested, blowing away the dust, oil, iron filings and other impurities attached to the surface of the water pump, ensuring that the laser detector can accurately receive the reflected signal in the subsequent testing process, and avoiding impurities from interfering with the testing accuracy. (3) When the roller rolls to the side of the contact frame that is recessed inward, the spring will restore its elastic deformation, push the sealing plate and connecting rod to move in the opposite direction, so that the roller always keeps in contact with the outer surface of the contact frame. At the same time, a negative pressure will be formed inside the air supply box, and air will be drawn from the outside through the connecting hose to reserve air source for the next cleaning operation. (4) When the roller rolls to the side of the contact frame that protrudes outward, the fixed magnetic ring fixedly connected to the outside of the roller will also move synchronously to the position corresponding to the swing magnet. Since the magnetic properties of the fixed magnetic ring and the swing magnet are opposite, a strong attraction will be generated between them. Under the drive of the magnetic force, the swing magnet will drive the swing plate and the rotating shaft to rotate. The rotation of the rotating shaft will drive the cleaning tube at its upper end to swing synchronously, so that the opening of the cleaning tube can sweep back and forth within a certain angle range, so that the high-speed airflow can cover a wider cleaning area, further improve the cleaning effect, ensure the cleanliness of the water pump surface, and provide a more reliable guarantee for the accuracy of laser detection.

[0020] 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 some embodiments of the present invention, and not all embodiments. 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.

[0021] Example 1: As Figure 1 - Figure 4The present invention provides the following technical solution: a component wear detection mechanism for water pump failure. The equipment housing 1 has a placement rack 8 for placing the water pump to be tested inside. The equipment housing 1 also has a drive assembly with two sets of laser detectors 2. The water pump is tested using the two sets of laser detectors 2. The drive assembly includes a limit frame 7, which is fixedly connected to the upper surface of the equipment housing 1. The upper surface of the equipment housing 1 has front and rear drive components 5, and the output side of the front and rear drive components 5 has front and rear mounting plates 6. The front and rear mounting plates 6 are slidably connected to the upper surface of the limit frame 7, limiting the front and rear mounting plates 6. The limit frame 7 limits the front and rear mounting plates 6. The upper surface of the front and rear mounting plates 6 has a transverse drive component 3. A transverse mounting plate 4 is provided on the output side of the drive component 3, and a limit frame 7 is also fixedly connected to the front side of the front and rear mounting plates 6. The transverse mounting plate 4 and the limit frame 7 provided on the front side of the front and rear mounting plates 6 are slidably connected. The laser detector 2 is fixedly connected to the front side of the transverse mounting plate 4. The output ends of the two sets of laser detectors 2 are set accordingly. The two sets of laser detectors 2 are located on the upper and lower sides of the placement frame 8, respectively, so that the wear condition of the component can be scanned and detected from the radial and axial dimensions of the water pump. An auxiliary plate 12 is fixedly connected to the lower inner side of the placement frame 8, and a soft pad 15 is fixedly connected to the upper surface of the auxiliary plate 12. The water pump to be processed is placed on the upper surface of the soft pad 15. The soft pad 15 plays a buffering and protection role for the bottom of the water pump, preventing the water pump from being damaged by collision during placement or testing.

[0022] In actual operation, the water pump to be tested is placed stably on the surface of the soft pad 15 on the inner auxiliary plate 12 of the placement rack 8. The soft pad 15 is made of high-density elastic material, and its softness can effectively absorb the impact force generated when the water pump is placed, avoiding direct contact between the bottom of the water pump and the hard auxiliary plate 12, which would cause scratches or deformation. Then, the equipment is started, and the front and rear drive components 5 start to work. The drive motor inside drives the front and rear mounting plates 6 connected to it to move back and forth along the limit frame 7 fixed on the upper surface of the equipment housing 1 through gear and rack transmission or ball screw structure. The limit frame 7 has an "I" shaped cross section. The bottom of the front and rear mounting plates 6 is provided with a sliding groove that matches the limit frame 7. Wear-resistant sliders are embedded in the sliding groove. The transverse drive component 3 on the upper surface of the front and rear mounting plates 6 is also started simultaneously. Its working principle is similar to that of the front and rear drive components 5. It drives the transverse mounting plate 4 to slide laterally along the limit frame 7 on the front side of the front and rear mounting plates 6.

[0023] Since the laser detector 2 is fixed on the front side of the horizontal mounting plate 4, the two sets of laser detectors 2 will achieve two-dimensional composite motion in the front-back and lateral directions under the drive of the drive component. The upper laser detector 2 mainly emits laser beams from the radial direction of the water pump to scan the radial wear of the water pump impeller, the radial runout of the pump shaft, and the radial wear of the inner wall of the pump casing. The lower laser detector 2 focuses on scanning from the axial direction to detect parameters such as the axial movement of the impeller, the axial wear of the seals, and the axial clearance of the bearings. The two sets of laser detectors 2 quickly acquire the three-dimensional coordinate data of the surface of the water pump components and transmit it to the control system of the equipment in real time for processing and analysis.

[0024] Example 2: Figure 4 - Figure 7 The present invention provides the following technical solution: a component wear detection mechanism for a water pump malfunction. A fixed frame 13 is fixedly connected to the side of the placement frame 8. A cleaning mechanism is provided on the fixed frame 13. The cleaning mechanism cleans impurities on the surface of the water pump to be tested by changing the position of the laser detector 2, avoiding interference from impurities to subsequent testing. The cleaning mechanism includes an air supply box 9, which is fixedly connected to a horizontal mounting plate 4. A sealing plate 23 is slidably connected inside the air supply box 9, and the side of the sealing plate 23 is in contact with the inner wall of the air supply box 9. A connecting rod 25 is fixedly connected to one side of the sealing plate 23. Meanwhile, a spring 24 is fixedly connected between the side of the sealing plate 23 and the inner wall of the air supply box 9. The connecting rod 25 is slidably connected to the side of the air supply box 9, and the outer end of the connecting rod 25 is fixedly connected to the mounting bracket 22. A roller 17 is rotatably connected to the mounting bracket 22. A contact bracket 16 is fixedly connected to the side of the fixing bracket 13. The contact bracket 16 is arranged in a zigzag structure. The outer side of the roller 17 is in contact with the outer side of the contact bracket 16. A rotating shaft 21 is rotatably connected to the fixing bracket 13. A cleaning pipe 10 is fixedly connected to the upper end of the rotating shaft 21. A connecting hose 11 is connected through the upper end of the cleaning pipe 10 and the air supply box 9.

[0025] When the laser detector 2 begins scanning, the cleaning mechanism first cleans the surface of the water pump. When the drive assembly moves the front and rear mounting plates 6 closer to the placement frame 8, the air supply box 9 mounted on the horizontal mounting plate 4 moves along with it. At this time, the roller 17 on the outer end of the mounting frame 22 of the connecting rod 25 on the side of the air supply box 9 begins to contact the outer surface of the contact frame 16 on the side of the fixed frame 13. When the horizontal mounting plate 4 moves the roller 17 laterally, the roller 17 rolls along the outer contour of the contact frame 16. When the roller 17 rolls to the section of the contact frame 16 that protrudes outward, the contact frame 16 exerts pressure on the roller 17. A squeezing force is applied towards the interior of the air supply box 9. This squeezing force is transmitted to the connecting rod 25 through the mounting bracket 22, which in turn pushes the sealing plate 23 to slide inward against the elastic force of the spring 24 within the air supply box 9. Since the sealing plate 23 is tightly attached to the inner wall of the air supply box 9, its sliding will compress the air inside the air supply box 9, causing the air pressure inside the box to rise. The high-pressure air is then quickly delivered to the cleaning pipe 10 through the connecting hose 11. The cleaning pipe 10 delivers the gas to the surface of the water pump, causing the dust attached to the surface of the water pump to be blown away, and heavier impurities such as metal shavings to be blown away and fall off, thereby forming a clean detection surface in the laser detection area.

[0026] When the roller 17 rolls to the inwardly recessed section of the contact frame 16, the squeezing force acting on the roller 17 disappears. At this time, the compressed spring 24 begins to release its elastic potential energy, pushing the sealing plate 23 to move outward. The connecting rod 25 and the mounting bracket 22 also return to their original positions. Under the action of the spring 24, the roller 17 always maintains good contact with the outer surface of the contact frame 16. During the outward movement of the sealing plate 23, a negative pressure is formed inside the air supply box 9. Outside air is drawn into the air supply box 9 through the connecting hose 11 from the opening of the cleaning pipe 10, thus replenishing the air source and preparing for the next cleaning operation.

[0027] Example 3: Figure 6 - Figure 8 The present invention provides the following technical solution: a component wear detection mechanism for water pump failure, wherein a through groove 14 is provided on the fixed frame 13, the lower end of the rotating shaft 21 extends into the interior of the through groove 14, and swing plates 20 are fixedly connected to the left and right sides of the rotating shaft 21. A swing magnet 19 is fixedly connected to the outer end of the swing plate 20. The swing magnet 19 is located corresponding to the outward protrusion side of the contact frame 16. A fixed magnetic ring 18 is fixedly connected to the outer side of the roller 17, and the magnetic properties of the fixed magnetic ring 18 are opposite to those of the swing magnet 19.

[0028] As the roller 17 rolls to the outwardly protruding side of the contact frame 16, the fixed magnetic ring 18 fixed on the outer side of the roller 17 moves to the position corresponding to the swing magnet 19 at the outer end of the swing plate 20 in the through groove 14 of the fixed frame 13. Since the magnetic properties of the fixed magnetic ring 18 and the swing magnet 19 are opposite, the magnetic attraction between them will pull the swing magnet 19 towards the fixed magnetic ring 18, thereby causing the swing plate 20 to rotate around the rotating shaft 21. The upper end of the rotating shaft 21 is fixedly connected to the cleaning tube 10, so the cleaning tube 10 will swing left and right as the rotating shaft 21 rotates. The oscillation allows the airflow from the cleaning pipe 10 to sweep across the surface of the water pump. For grooves on the water pump surface, such as the flow channels between impeller blades, the airflow can penetrate deep into them and blow out the accumulated dust. For corners, such as the corners where the pump casing and pump cover are connected, the oscillating airflow can also cover them, ensuring that impurities are thoroughly removed. When the roller 17 leaves the protruding section of the contact frame 16, the distance between the fixed magnetic ring 18 and the oscillating magnet 19 increases, and the magnetic attraction weakens. When the roller 17 moves to the corresponding position of the oscillating magnet 19 on the other side, the cleaning pipe 10 rotates in the opposite direction to further perform the cleaning operation.

[0029] Through the precise driving of the aforementioned drive components and the synergistic effect of the cleaning mechanism, this pump failure component wear detection mechanism can achieve automated, high-precision, and multi-dimensional detection of pump components. It effectively solves the problems of impurity interference and single detection dimension in traditional detection methods, providing reliable technical support for pump fault diagnosis and maintenance.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
