Description

Technical Field

[0001] This utility model relates to the field of vibration measuring instruments, and in particular to a vibration and sway monitoring device for pumped storage units. Background Technology

[0002] The multi-functional vibration detector is a machine condition monitoring instrument based on the latest microprocessor design. It has vibration detection, bearing condition analysis and infrared temperature measurement functions. It is easy to operate, automatically indicates status and alarms, and is very suitable for on-site equipment operation and maintenance personnel to monitor equipment status, detect problems in time, and ensure the normal and reliable operation of equipment.

[0003] Now, manual multi-functional vibration measuring instruments are used to inspect the water pumps in pumped storage units, thereby preventing equipment failures and damage. For example, problems such as bearing wear, imbalance, and loosening can be detected in advance, reducing equipment downtime and maintenance costs, and extending the service life of the equipment.

[0004] However, when using a multi-functional vibration measuring instrument, one end of the probe is magnetically attached to the surface of the water pump, thus limiting the probe's position. This causes metal objects or small metal fragments to be attracted when the probe is not in use and is stored, affecting subsequent use of the probe and making cleaning inconvenient.

[0005] Therefore, it is necessary to provide a pumped storage unit vibration monitoring device to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a pumped storage unit vibration monitoring device provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the protective sleeve. Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. A pumped-storage unit vibration monitoring device includes:

[0028] Body 1, with a connecting wire 2 inside the body 1, and a probe 3 fixedly installed at one end of the connecting wire 2;

[0029] A limiting ring 31 is provided on the surface of the probe 3. A return spring 33 is provided on one side of the limiting ring 31. A sliding sleeve 32 is provided at one end of the return spring 33. A protective sleeve 34 is fixedly connected to one end of the sliding sleeve 32.

[0030] A rotating rod 4 is disposed on one side of the protective sleeve 34. A protective cover 5 is fixedly connected to the surface of the rotating rod 4, and a magnet 6 is fixedly connected inside the protective cover 5.

[0031] The limiting ring 31 is fixedly connected to the surface of the probe 3, and the reset spring 33 is located between the limiting ring 31 and the sliding sleeve 32 and is sleeved on the surface of the probe 3.

[0032] Both the sliding sleeve 32 and the protective sleeve 34 are slidably connected to the surface of the probe 3.

[0033] Both the protective cover 5 and the protective sleeve 34 have magnets 6 fixedly connected inside.

[0034] A rectangular block is fixedly connected to one side of the protective sleeve 34, one end of the rotating rod 4 is rotatably connected to the bottom of the rectangular block, and the protective cover 5 is fixedly connected to the surface of the rotating rod 4.

[0035] The magnet 6 is ring-shaped and is used to limit the protective cover 5 by attracting each other after the protective cover 5 is rotated to a suitable position.

[0036] The protective cover 5, protective sleeve 34, and sliding sleeve 32 are all made of plastic to prevent them from adhering to the surface of the probe.

[0037] The main body 1 is a multi-functional vibration detector, while the connecting cable 2 and probe 3 are used in conjunction with the main body 1 to detect the water pumps in the pumped storage unit, thereby preventing equipment failure and damage, such as early detection of bearing wear, imbalance, loosening and other problems, reducing equipment downtime and maintenance costs, and extending the service life of the equipment.

[0038] The working principle of the vibration monitoring device for pumped storage units provided by this utility model is as follows:

[0039] When using probe 3, rotate the protective cover 5 to one side, thereby rotating the rotating rod 4 to one side to the appropriate position.

[0040] By moving the sliding sleeve 32 to one side, the sliding sleeve 32 moves to one side on the surface of the probe 3, thereby squeezing the reset spring 33. When the sliding sleeve 32 moves to one side, it drives the protective sleeve 34 to move to a suitable position, so that the probe 3 can be removed from the inside of the protective sleeve 34.

[0041] When the use is finished, after the sliding sleeve 32 is released, the reset spring 33 pushes the sliding sleeve 32 to move to one side on the surface of the probe 3, thereby moving the protective sleeve 34 to a suitable position. After the protective cover 5 is rotated to one side to reset, the magnet 6 inside the protective cover 5 and the magnet 6 inside the protective sleeve 34 attract each other and limit the protective cover 5.

[0042] Compared with related technologies, the vibration monitoring device for pumped storage units provided by this utility model has the following advantages:

[0043] This utility model provides a vibration monitoring device for pumped storage units. By using a limiting ring 31 in conjunction with a sliding sleeve 32 and a return spring 33, the sliding sleeve 32 moves to one side, causing the protective sleeve 34 to move as well, allowing the probe to be removed to one side for convenient use. The protective sleeve 34, in conjunction with a protective cover 5, seals and protects the probe 3, preventing the adsorption of metal debris and metal objects and thus preventing damage to the probe when it is stored.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application providing a pumped-storage unit vibration monitoring device, the second embodiment of this application proposes another pumped-storage unit vibration monitoring device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the difference between the second embodiment of this application and the pumped storage unit vibration monitoring device is that the sliding sleeve 32 of the pumped storage unit vibration monitoring device has a fixing hole 10 inside, and a fixing pin 11 is threadedly connected inside the fixing hole 10.

[0047] One end of the fixing pin 11 is fixedly connected to a rotating handle for easy rotation of the fixing pin 11.

[0048] The sliding sleeve 32 has a moving groove 7 inside, and a moving block 8 is slidably connected inside the moving groove 7. An anti-slip pad 9 is fixedly connected to one side of the moving block 8.

[0049] One end of the fixing pin 11 is rotatably connected to one side of the moving block 8.

[0050] The fixing pin 11 is a bolt, and the fixing hole 10 is a threaded hole that is adapted to the fixing pin 11. When the fixing pin 11 rotates to one side, the fixing pin 11 moves to one side inside the fixing hole 10, thereby driving the moving block 8 to move to one side.

[0051] One end of the movable block 8 is an arc shape that fits the surface of the probe 3, which is used to increase the contact area between the block and the surface of the probe 3, thereby increasing the fixation effect.

[0052] The anti-slip pad 9 is made of rubber and is used to increase the friction between the moving block 8 and the probe 3, thereby increasing the fixation effect.

[0053] The working principle of the vibration monitoring device for pumped storage units provided by this utility model is as follows:

[0054] When in use, when it is necessary to limit the sliding sleeve 32, the fixing pin 11 is rotated to one side, thereby moving to one side inside the fixing hole 10. When the fixing pin 11 moves to one side, it drives the moving block 8 to move to one side inside the moving groove 7. When one end of the moving block 8 contacts the surface of the probe 3, the sliding sleeve 32 can be limited.

[0055] After use, the fixing pin 11 is reversed, causing it to move to one side inside the fixing hole 10. This causes the moving block 8 to move to one side inside the moving groove 7, separating one end of the moving block 8 from the probe 3, thus allowing the sliding sleeve 32 to move.

[0056] Compared with related technologies, the vibration monitoring device for pumped storage units provided by this utility model has the following advantages:

[0057] This utility model provides a pumped storage unit vibration monitoring device. By using a fixing pin 11 and a fixing hole 10, the moving block 8 moves to one side inside the moving groove 7 and contacts the surface of the probe 3, thereby limiting the sliding sleeve 32. After the probe 3 is moved out, the sliding sleeve 32 is limited, which facilitates the subsequent use of the probe 3.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
