Problems solved by technology

For a running unit, if there is a quality problem with the blades, it will not only be expensive to repair and replace, but also affect the stability and safety of the entire unit operation, especially for large offshore wind turbine blades, the costs of transportation, hoisting and maintenance are all high. It is very high, so it is very important to find defects at the manufacturing stage through effective inspection methods

Embodiment 1

[0041] This embodiment uses an OLYMPUS EPOCH 600 / 650 ultrasonic flaw detector and an OLYMPUS V101 (0.5MHz 1 inch) probe.

[0042] like figure 1 As shown, a non-destructive testing method for the bonding area of ​​a wind turbine blade web, which includes the following steps:

[0043] (1) Determination of the starting point and end point of the web bonding area

[0044] (1.1) If figure 1 As shown, first place the probe on the E-D surface of the web core material area, set the bottom wave height of the web core material to 80% of the full screen height; then move the probe slowly to point C, when the web core material echo Stop when the amplitude drops 6dB, this point is point D; then move the probe slowly towards point B, stop when the echo amplitude of the web core material drops 6dB, this point is point E or the bonding area of ​​the web starting point;

[0045] (1.2) Then place the probe on the C-D surface of the web bonding area, set the echo height of the bottom surface...

Abstract

The invention discloses a nondestructive detection method for the web plate bonding area of a wind turbine blade. The nondestructive detection method comprises the following steps: firstly, determining the starting point and the finishing point of the web plate bonding area; and secondly, performing nondestructive detection on the overall web plate bonding adhesive area B-F within the chord direction range by using ultrasonic longitudinal waves. The nondestructive detection method for the web plate bonding area of the wind turbine blade provided by the invention has the benefits as follows: the specific location of web plates in the blade is determined precisely by positioning the web plate core materials, and whether the web plates are dislocated or not can also be determined; moreover, the effective width of the bonding adhesive of the web plates can be detected in the true sense, that is, not only is the width of the bonding adhesive detected, but also the measured bonding width isensured to be consistent with that required by drawings; and besides, through the detection on the defects of the adhesive layer in the bonding area of the web plates, whether the bonding between theweb plates and the main beams meets the drawing and process requirements or not is recognized, and the bonding quality of the blade is ensured.

Description

technical field [0001] The invention relates to a quality detection device for a wind turbine blade, in particular to a nondestructive detection method for a web bonding area of ​​a wind power blade. Background technique [0002] With the rapid development of the wind power industry, wind turbines continue to develop towards large-scale trends, the length of the blades is also increasing, and the manufacturing cost of the blades is also becoming more and more expensive, which accounts for 10%-15% of the total cost of the whole machine. For a running unit, if there is a quality problem with the blades, it will not only be expensive to repair and replace, but also affect the stability and safety of the entire unit operation, especially for large offshore wind turbine blades, the costs of transportation, hoisting and maintenance are all high. It is very high, so it is very important to find defects at the manufacturing stage through effective inspection methods. Contents of t...
