Description

Technical Field

[0001] This utility model relates to the technical field of online wind turbine monitoring devices, and in particular to an online vibration monitoring data analysis device for wind turbines. Background Technology

[0002] During production, vibration monitoring of the fans inside the workshop is necessary to determine their working status. This is achieved through vibration sensors connected to terminals via LoRa transmission technology. LoRa is a long-range wireless data transmission and low-power local area network wireless standard. It extends the distance by 3-5 times compared to traditional wireless radio frequency communication at the same power consumption, achieving a balance between low power consumption and long range. In automated industrial production environments, numerous intelligent technologies are applied, and various information data converge in the network. Therefore, the characteristics of the network directly affect production efficiency. In some scenarios, sensors equipped with low power consumption and long battery life are required to track equipment and monitor its status.

[0003] Existing wind turbine testing devices use wired data acquisition, which is costly, has poor installation convenience, and is difficult to maintain. To address these issues, application number 202120846608.1 discloses an online testing device for wind turbines and water pumps. This device includes a wireless vibration sensor, a sensor magnetic ring, a LoRa wireless gateway, a host computer, and a data analysis module. The wireless vibration sensor is connected to the LoRa wireless gateway installed in the workshop, and the host computer has a built-in data analysis module. This invention connects the testing device itself to a vibration sensor installed inside the testing workshop via the LoRa wireless gateway. It offers high detection frequency, low maintenance difficulty, and the vibration sensor is externally equipped with a magnetic chuck, which is fixed to the outside of the testing equipment by the magnetic ring. This provides convenient installation, allows for multiple installation points, has high installation adaptability, saves wiring, and has a low failure rate.

Furthermore, it only requires drilling holes in a landscape housing of the same material and screwing it onto the fan housing, thus achieving a simple... This device can be installed on fan casings of different materials, expanding its applicability and greatly improving its practicality. The wireless vibration detection sensor 2 is connected to a host monitoring computer via a LoRa wireless gateway (shown in the figure). The wireless vibration detection sensor 2 monitors the vibration of the fan and transmits the monitored information to the host monitoring computer via the LoRa wireless gateway. The host monitoring computer then analyzes the data and transmits the analysis results to mobile clients and PC clients. The specific structure and working principle of the wireless vibration detection sensor 2 and the host monitoring computer can be found in the document with application number 202120846608.1, which is prior art and will not be described in detail here.

[0032] In this method, a connecting rod 3 is fixedly connected to one end of the wireless vibration detection sensor 2. The connecting rod 3 is inserted into the mounting base 1, and the locking block 4 is locked to the connecting rod 3. The interaction between the locking block 4 and the connecting rod 3 can achieve the effect of limiting the wireless vibration detection sensor 2.

[0033] In this method, one end of the rotating shaft 5 is threadedly connected to a loosening nut 6, and one side of the loosening nut 6 is in contact with the mounting base 1. Through the interaction between the loosening nut 6, the rotating shaft 5 and the mounting base 1, the rectangular rod 12 can be limited. One end of the rotating shaft 5 is provided with an external thread that is compatible with the loosening nut.

[0034] In this method, a rectangular rod 12 is welded to one end of the rotating shaft 5. The rectangular rod 12 is slidably connected to one side of the mounting base 1. A sliding groove 2 is provided on one side of the mounting base 1. The rectangular rod 12 slides in the sliding groove 2. By pushing the rotating plate 7, the rectangular rod 12 is moved into the sliding groove 2 on one side of the mounting base 1. At this time, the interaction between the sliding groove 2 and the rectangular rod 12 can achieve the effect of limiting the position of the locking block 4.

[0035] In this method, a rotating plate 7 is fixedly connected to one end of the rectangular rod 12, which makes it easy for the staff to rotate the locking block 4 inside the mounting base 1.

[0036] In this method, a sliding groove 9 is provided on the inner side of the card block 4, and a slider 8 is slidably connected in the sliding groove 9.

[0039] Then, insert the connecting rod 3 at one end of the wireless vibration detection sensor 2 into the slot 11, so that the slot 10 corresponds to the block 4. Then, by rotating the rotating plate 7, the rectangular rod 12 drives the rotating shaft 5 to rotate half a turn. At the same time, the interaction between the slider 8 and the sliding groove 1 causes the rotating shaft 5 to drive the block 4 to rotate half a turn synchronously, so that the block 4 engages with the slot 10. Then, push the rotating plate 7, and the rectangular rod 12 moves into the sliding groove 2 on one side of the mounting base 1. At this time, the interaction between the sliding groove 2 and the rectangular rod 12 can achieve the effect of limiting the block 4.

[0040] Next, the loosening nut 6 is installed on one end of the rotating shaft 5, and one side of the loosening nut 6 is in contact with the mounting base 1. At this time, through the interaction between the loosening nut 6, the rotating shaft 5 and the mounting base 1, the rectangular rod 12 can be limited.

[0041] In summary, the wireless vibration detection sensor 2 can be quickly installed without the need for additional tools; conversely, it can be quickly disassembled.

[0042] Finally, the vibration of the wind turbine is monitored by the wireless vibration detection sensor 2, and the monitored information is transmitted to the host monitoring computer through the LoRa wireless gateway. The host monitoring computer then performs data analysis on the information and transmits the analysis results to the mobile client and the PC client.
