[0002] The collection and analysis of turning gear data is of great significance for judging the operating status of the unit, predicting potential faults, and guiding operation and maintenance management. Through turning gear data, problems in unit operation can be identified and resolved in a timely manner, ensuring the safe, efficient, and stable operation of the unit. Data collection requires manually rotating the rotor one revolution to determine the deviation between the actual and theoretical center of the unit, and then adjusting the relative positions of various components along the unit's axis based on the measurements.

[0003] The existing spindle rotation data is collected manually, which cannot achieve synchronous data collection of all parts at the same time during the rotation of the main shaft, nor can it achieve data recording of the entire dynamic rotation process. Furthermore, the collected data needs to be verified multiple times to obtain relatively accurate measurement results, which prolongs the subsequent adjustment and processing period of the main shaft axis. Utility Model Content

[0004] The purpose of this utility model is to provide a data acquisition and analysis system for the turning gear of a hydro-generator unit. It aims to solve the problems of existing turning gear data acquisition relying on manual reading, which makes it impossible to keep the data of each part synchronously collected at the same time during the rotation of the main shaft, and also makes it impossible to record the data of the entire dynamic turning gear process. Furthermore, the collected data needs to be verified multiple times to obtain a more accurate measurement result, which prolongs the subsequent adjustment and processing period of the main shaft axis.

[0008] A relay transmitting module, connected to the data acquisition module, is used to transmit the turning gear data to the relay receiving module wirelessly or via wired means;

[0009] A relay receiving module, connected to the relay transmitting module, is used to receive turning data from the relay transmitting module and forward the turning data to the data analysis module;

[0010] The data analysis module, connected to the relay receiving module, is used to perform in-depth analysis and processing of the received turning gear data.

[0013] Optionally, two acquisition components are provided at each acquisition point.

[0014] Optionally, each acquisition layer is provided with at least two acquisition components and at least one relay transmission component.

[0015] Optionally, one of the relay transmitting components is connected to several of the acquisition components in the several acquisition layers.

[0020] The technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0021] This utility model provides a hydro-generator unit turning gear data acquisition and analysis system, comprising: a data acquisition module for real-time acquisition of turning gear data during the turning gear process, and displaying the turning gear data intuitively on a local interface in numerical or graphical form; a relay transmission module connected to the data acquisition module for transmitting the turning gear data to a relay receiving module via wireless or wired means; a relay receiving module connected to the relay transmission module for receiving the turning gear data from the relay transmission module and forwarding the turning gear data to a data analysis module; and a data analysis module connected to the relay receiving module for in-depth analysis and processing of the received turning gear data. The data acquisition module collects turning gear data from multiple locations of the hydro-generator unit in real time. The relay transmission module transmits the collected turning gear data wirelessly or via wired to the relay receiving module, which then feeds the data back to the data analysis module. The data analysis module performs in-depth analysis and processing on the received turning gear data and obtains corresponding analysis results. Operators use the turning gear data and analysis results displayed by the data analysis module to determine whether the turning gear data is qualified. This solves the problems of existing turning gear data collection methods that rely on manual readings, which cannot achieve synchronous data collection from all parts at the same time during the rotation of the main shaft, cannot record data throughout the dynamic turning gear process, and require multiple verifications of the collected data to obtain accurate measurement results, thus extending the subsequent adjustment and processing period of the main shaft axis.
