Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fan tower tube deviation adjustment, and particularly relates to a fan tower tube anti-inclination online automatic adjustment device and method. BACKGROUND

[0002] The tower tube is an important component of a wind turbine generator unit, and is connected between a nacelle and the ground. In order to facilitate hoisting and improve production efficiency, the tower tube is generally divided into several sections of 20-30m different conical tubes for production, and then the sections are connected through flanges. The tower tube supports the impeller to a certain height so that the impeller obtains a higher and stable wind speed, and supports the nacelle to provide a working platform for installation, operation and maintenance of the generator and other equipment. The reliability of the structure is one of the necessary factors affecting the safe and stable operation of the wind turbine generator unit. The wind in nature changes at any time, and is irregular in space and time. When the wind speed and direction change, the moment generated by the tower tube at different heights also changes. When the wind force exceeds the critical state, the tower tube will be greatly inclined, which may cause a tower collapse accident, causing significant economic losses and threatening the personal safety of the unit operation and maintenance personnel.

[0003] At present, the inclination of the fan tower tube is mainly measured offline by an optical level gauge and a GPS receiver at a certain period. In order to observe the real-time change of the inclination, a real-time online detection system has also been rapidly developed. The system extracts the data of the inclination sensor, sends the data to a remote server through a network module, analyzes and stores the collected signals, and then monitors the online inclination state of the tower tube in real time. However, the data obtained by the two methods is only used to evaluate the running state of the tower tube inclination. When the inclination exceeds the standard during the operation of the fan, the operation and maintenance personnel can only adjust it through basic deviation correction and other measures after the machine is stopped, which is high in cost and long in period, and the inclination treatment capacity of the tower tube cannot meet the expected time requirement.

[0043] Further, the inclination angle measuring device includes a laser range finder 2 and a detection seat 3. The laser range finder 2 is installed at the top center position of the fan tower 1, and the detection seat 3 is arranged at the bottom of the fan tower 1 and provided with a mark point corresponding to the center position of the bottom of the fan tower 1. A camera 4 is installed on the detection seat 3.

A plurality of laser range finders 2 are arranged, and each laser range finder 2 is installed at the top center position of each cone cylinder 10. By arranging a plurality of laser range finders 2 and installing them at the top center of each cone cylinder 10 that constitutes the fan tower 1, a plurality of discrete projection points are projected on the detection seat 3 by the plurality of laser range finders 2. At this time, the signal acquisition and processing device 5 receives the image information and establishes a coordinate system in the image information (as shown in Figure 8As shown in the figure, the offset value is calculated based on the coordinate increment between multiple projection points in the coordinate system, thereby realizing the detection of the node status of multiple cones 10 that make up the wind turbine tower 1 and are connected together, further improving the detection accuracy, and realizing the detection of the overall tilt of the wind turbine tower 1 and the tilt of the connection node of a single cone 10. The detection data is more comprehensive, and the detection of the wind turbine tower 1 is better realized, providing sufficient data support for the maintenance and repair of the wind turbine tower 1.

[0045] A method for online automatic adjustment of wind turbine tower tilt prevention, based on the aforementioned online automatic adjustment device for wind turbine tower tilt prevention, includes the following steps:

[0046] S1: The offset data of the wind turbine tower 1 is measured by the tilt angle measuring device, and the measured data is wirelessly transmitted to the signal acquisition and processing device 5; specifically, the laser rangefinder 2 located at the circular position at the top of the wind turbine tower 1 projects light onto the detection seat 3. At this time, the camera 4 collects the image information of the light spot projected by the laser rangefinder 2 on the detection seat 3 and the marked point thereon, and wirelessly transmits it to the signal acquisition and processing device 5.

[0047] S2: The signal acquisition and processing device 5 analyzes the measured data to assess the tilt status of the wind turbine tower 1 and calculates the tilt adjustment data for the wind turbine tower 1; wherein, the tilt status assessment of the wind turbine tower 1 includes the overall tilt status assessment of the wind turbine tower 1 and the tilt status assessment of each cone 10 composed of the wind turbine tower 1.

[0048] Signal acquisition and processing device 5 receives image information and establishes a coordinate system (e.g., ...) within the image information. Figure 8 As shown in the figure, x0 and y0 are the coordinates of the center p0 of the bottom surface of the wind turbine tower 1, and xi and yi are the coordinates of the center pi of the section with height i. If x0 ≠ xi and y0 ≠ yi, it means that the center of the bottom surface of the wind turbine tower 1 and the center of the section do not coincide in the vertical plane, and the tower is tilted. The specific steps for evaluating the overall tilt state of the wind turbine tower 1 are as follows:

[0049] S2.1: Then calculate the coordinate increments, Δx = xi - x0, Δy = yi - y0;

[0050] S2.2: Recalculate the offset value:

[0051] S2.3: Calculate the inclination:

[0052] S2.4: Calculate the tilt direction

[0053] S2.5: According to the inclination tanθ obtained by calculation, comparative analysis is carried out, and when the inclination tanθ exceeds the provisions of NB / T10311-2019 “Land-based wind farm engineering wind turbine generator foundation design rules” 6.4.1 (when the hub height H≤70m, tanθ=0.006; 70m<H≤90m, tanθ=0.005; 90m<H≤120m, tanθ=0.004; H>120m, tanθ=0.003; wherein H is the hub height, and the allowable value tanθ is the threshold value), a warning is given and the inclination adjustment data of the wind turbine tower 1 is calculated;

[0054] The inclination state evaluation of each cone 10 composed of the wind turbine tower 1 is the same as above, and the difference is that the inclination of all adjacent two projection points is calculated and integrated evaluation analysis is carried out.

[0055] S3: Based on the inclination adjustment data of the wind turbine tower 1 calculated by the signal acquisition and processing device 5, the inclination of the wind turbine tower 1 is adjusted by the inclination adjustment device. Specifically, the traction steel rope 7 is coiled and coiled by the winch for rough adjustment, and then the driving sliding seat 62 of the hydraulic telescopic rod 63 is adjusted to slide on the guide rail frame 61 to realize fine adjustment, and when one inclination adjustment device is adjusted, the remaining inclination adjustment devices are kept loose at this time to meet the needs of traction adjustment, and when the adjustment is completed, the sliding seat 62 is locked and fixed on the guide rail frame 61 by the locking mechanism 65, so as to avoid that the hydraulic telescopic rod 63 is subjected to the reaction force of the wind turbine tower 1 through the traction steel rope 7 under the action of wind force, resulting in that the hydraulic telescopic rod 63 bears fluctuating load in real time, thereby realizing protection of the hydraulic telescopic rod 63 and prolonging the service life of the hydraulic telescopic rod 63. The inclination of the wind turbine tower 1 is adjusted by the inclination adjustment device, wherein when the inclination of the wind turbine tower after adjustment is less than one-third of the provisions of NB / T10311-2019 “Land-based wind farm engineering wind turbine generator foundation design rules” 6.4.1 (such as when the hub height H≤70m, tanθ≤0.002 after adjustment), the adjustment is stopped, and when the inclination tanθ of the wind turbine tower 1 exceeds the threshold value, the adjustment is carried out again, so as to repeatedly adjust the real-time dynamic picture to adjust the inclination of the wind turbine tower 1.
