Abstract
Description
Technical Field
[0001] This utility model relates to the field of pump blade detection technology, specifically a pump blade detection device for preventing leakage during material discharge. Background Technology
[0002] In the field of fluid transportation, the leak-proof performance of pump equipment is directly related to production safety, resource utilization and environmental friendliness. As the core component inside the pump body that directly acts on the fluid, the pump blade's contour accuracy, edge flatness and surface integrity are the key factors that determine the leak-proof effect. If the blade has gaps, uneven thickness or surface damage, it will cause backflow and leakage of fluid during transportation, which will not only reduce the pump's operating efficiency, but may also cause media waste, equipment corrosion or even safety accidents. Therefore, extremely high requirements are placed on the quality inspection of pump blades. The existing devices have insufficient buffering and adjustment capabilities. Most clamping mechanisms do not have effective buffering structures or only use a single spring buffer, which is difficult to absorb the instantaneous impact force during the clamping process. When facing pump blades of different thicknesses and specifications, they cannot flexibly adapt to the clamping requirements. Either the blades are unstable due to insufficient clamping force, or the blades are damaged due to excessive clamping force. Therefore, the linkage between the buffering structure and the clamping action is poor. The hydraulic system cannot respond to changes in clamping force in time, which further reduces the clamping stability and adaptability, and restricts the improvement of detection efficiency and detection quality. Therefore, a pump blade detection device to prevent leakage during material discharge is proposed to address the above problems. Utility Model Content

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: A pump blade detection device for preventing leakage of material discharge includes a laser detector 1, a detection plate 2 is provided at the bottom of the laser detector 1, and a clamping mechanism 3 is provided at the top of the detection plate 2. The clamping mechanism 3 includes a stabilizing plate 31, a movable tube 32 is fixedly connected to the outside of the stabilizing plate 31, a nylon rod 33 is movably engaged inside the movable tube 32, a clamping cover 34 is fixedly connected to the outside of the nylon rod 33, and a return spring 35 is sleeved on the nylon rod 33. The outer side of the stabilizing plate 31 is fixedly connected to the operating box 311. The operating box 311 is equipped with an elastic oil bladder 312 and a buffer plate 313. The outer side of the elastic oil bladder 312 is fixedly connected to an oil guide pipe 314. The top of the operating box 311 is snapped with an oil inlet cover 315.
[0017] It should be noted that: the stabilizing plate 31 is fixed and symmetrically distributed on the top of the detection plate 2, the movable tube 32 is symmetrically distributed on the outside of the stabilizing plate 31, the clamping cover 34 is movably connected to the outside of the stabilizing plate 31 through the cooperation of the nylon rod 33 and the return spring 35, and the clamping cover 34 is symmetrically distributed above the detection plate 2, the buffer plate 313 is located on the outside of the elastic oil bladder 312, the oil guide tube 314 is symmetrically distributed on the outside of the elastic oil bladder 312, and the end of the oil guide tube 314 away from the elastic oil bladder 312 is fixedly connected to the inside of the movable tube 32.
[0018] Specifically: Laser detector 1 is the core detection component. Its main function is to emit a detection beam to scan and detect defects related to size, contour, and material leakage on the clamped and fixed pump blades. Simultaneously, it receives and transmits detection data to provide a basis for blade quality judgment. It is the core component for achieving "precise detection." Detection plate 2, as the basic support structure, is fixedly connected to the bottom of laser detector 1 in a horizontal position, with the top serving as the placement area for the pump blades. Its surface is flat and perpendicular to the detection beam path of laser detector 1, ensuring a stable detection benchmark after blade placement. It also provides a mounting carrier for clamping mechanism 3, ensuring the symmetrical distribution of all clamping components.
[0019] Furthermore: The return spring 35 is sleeved on the outside of the nylon rod 33, with its two ends abutting against the stabilizing plate 31 and the clamping cover 34 respectively. In its natural state, it is in an extended state, which can keep the clamping cover 34 open. When clamped, it is compressed to generate reverse elastic tension, providing a stable clamping force for the clamping cover 34. At the same time, after the test, it pushes the nylon rod 33 to return to its original position, realizing the automatic opening of the clamping cover 34. The clamping components of the clamping cover 34 that directly contact the blade are symmetrically distributed above the detection plate 2. The inner side is fixedly connected to the nylon rod 33, and the outer side is attached with a rubber pad 341. Its shape is adapted to the edge of the pump blade, which can increase the contact area with the blade. Together with the rubber pad 341, it can achieve "flexible clamping" and avoid damage to the blade. At the same time, the top is fixed with a connecting rod 342 to realize linkage with the buffer structure.
[0020] As a further implementation of this solution, a rubber pad 341 is provided on the outside of the clamping cover 34, a connecting rod 342 is fixedly connected to the top of the clamping cover 34, and a compression cover 343 is fixedly connected to the outside of the connecting rod 342.
[0021] It should be noted that: the two rubber pads 341 are on the same plane, the connecting rod 342 runs through the inner wall of the operating box 311, the extrusion cover 343 is movably connected to the inside of the operating box 311 through the connecting rod 342, and the extrusion cover 343 is located on the outside of the elastic oil bladder 312.
[0022] Furthermore, the elastic oil bladder 312 is located inside the operating box 311. It is a flexible, sealed bladder filled with hydraulic oil and connected to the oil guide pipe 314 on the outside. When squeezed by the compression shield 343, the internal hydraulic oil can flow to the movable pipe 32 through the oil guide pipe 314, forming a hydraulic buffer. After the external force disappears, it can rely on its own elasticity to restore its original shape, driving the hydraulic oil to flow back. It is the core energy storage component of the hydraulic buffer system. The buffer plate 313 is located outside the elastic oil bladder 312 inside the operating box 311. It is made of elastic material and can absorb part of the impact force transmitted by the compression shield 343. It assists the elastic oil bladder 312 in adjusting the clamping force, avoiding blade deformation due to excessive instantaneous clamping force, and further improving the buffering effect.
[0023] Specifically: The oil inlet cover 315 is snapped onto the top of the operating box 311 and is a detachable sealing cover. After opening, hydraulic oil can be added to the elastic oil bladder 312 to solve the problem of hydraulic oil loss during long-term use and ensure the long-term stable operation of the hydraulic buffer system. At the same time, the rubber pad 341 is pasted on the outside of the clamping cover 34. The two rubber pads 341 are kept on the same plane. The material is soft and has anti-slip properties. On the one hand, it can avoid surface scratches caused by rigid contact between the clamping cover 34 and the blade. On the other hand, it can increase the friction with the blade and improve the clamping stability.
[0024] Work process: When the device is not working, the return spring 35 in the clamping mechanism 3 is in a naturally extended state, which drives the nylon rod 33 to maintain its initial position in the movable tube 32, so that the symmetrically distributed clamping covers 34 are in an open state, and the rubber pads 341 on the outside of the two clamping covers 34 are kept on the same plane. The elastic oil bladder 312 in the rotating box 311 outside the stabilizing plate 31 in the clamping mechanism 3 is not squeezed by external force. The internal hydraulic oil is kept in balance between the movable tube 32 and the elastic oil bladder 312 through the oil guide pipe 314. The buffer plate 313 is in a relaxed state, the laser detector 1 is on standby, and the detection plate 2 at its bottom provides support for the placement of the blade. After the pump blade to be tested is placed in the clamping area at the top of the test plate 2, external force pushes the clamping covers 34 on both sides to move towards the blade. The nylon rod 33 slides along the movable tube 32. The return spring 35 is compressed to generate a reverse elastic force. The rubber pad 341 contacts the blade first to avoid scratching. At the same time, the elastic tension of the return spring 35 ensures stable clamping to prevent blade displacement. During this process, the connecting rod 342 at the top of the clamping cover 34 moves synchronously with the clamping cover 34. Because the connecting rod 342 passes through the inner wall of the operating box 311, it will drive the end of the extrusion cover 343 to move towards the elastic oil bladder 312. The extrusion cover 343 extrudes the elastic oil bladder 312 to deliver hydraulic oil to the movable tube 32 through the oil guide tube 314, forming a hydraulic buffer for the sliding of the nylon rod 33. The buffer plate 313 further absorbs the impact force to adapt to blades of different specifications. After the clamping mechanism 3 completes stable clamping, the laser detector 1 starts detection. Because the stabilizing plate 31, the movable tube 32 and the clamping cover 34 are symmetrically distributed and the rubber pad 341 ensures the flatness of the blade, the coaxiality and flatness of the blade positioning can be ensured, avoiding detection benchmark deviation. The laser detector 1 emits a beam to scan and detect the blade size, outline and related defects of material leakage. The detection data is transmitted and analyzed in real time to determine whether the blade is qualified. After the test is completed, the external force on the clamping cover 34 is removed. The return spring 35 releases its potential energy to push the nylon rod 33 to slide in the opposite direction along the movable tube 32, causing the clamping cover 34 to open so that the blade can be removed. After the elastic oil bladder 312 loses its compression, the hydraulic oil flows back through the oil guide tube 314. The compression cover 343 returns to its original position with the connecting rod 342, the buffer plate 313 relaxes, and the device returns to its initial state to wait for the next cycle. If hydraulic oil needs to be replenished, it can be added to the elastic oil bladder 312 through the oil inlet cover 315 on the top of the operating box 311 to ensure the stable operation of the hydraulic buffer system.
