[0009] Beneficial effects: 1. When performing the mold seam inspection of wind turbine blades, the suction cup on the support base is attached to the side surface of the wind turbine blade to be inspected. Then, according to the location of the mold seam to be inspected, the outer sliding support frame is adjusted to a horizontal state, so that the first measuring claw and the second measuring claw correspond to the mold seam to be inspected. At this time, the measuring mechanism bearing shell is pushed to make the first measuring claw and the second measuring claw engage inside the mold seam to be inspected. During the process of the first measuring claw and the second measuring claw engaging inside the mold seam to be inspected, the inclined surfaces of the first measuring claw and the second measuring claw are in contact with the mold seam to be inspected. The device slides along the edge of the mold joint until the flat surfaces of the first and second measuring jaws contact the inner wall of the mold joint to be inspected. As the first and second measuring jaws move, the hydraulic oil inside the external linkage hydraulic cylinder is forced into the internal linkage hydraulic cylinder, causing the rack drive block to be pushed out. The rack drive block controls the movement of the dimension scale pointer in the dimension scale groove through the gear mechanism consisting of the driving rack, the first gear, the second gear, and the driven rack, thereby displaying the width of the measured gap. The device is easy to pick up and put down, and the measurement is accurate. It does not require external power, making the measurement operation more convenient and faster.

[0010] 2. The cross-sectional area of ​​the external linkage hydraulic cylinder of this utility model is much larger than that of the internal cross-sectional area of ​​the first and second internal linkage cylinders. At the same time, the radius of the second gear is larger than that of the first gear. This allows the relatively small relative movement between the first and second measuring jaws to be expanded into a larger range of movement for the pointer of the dimension scale, making it more convenient for operators to take measurements and making the measurements more accurate.

[0011] 3. The measuring mechanism of this utility model has a support structure consisting of an inner sliding support frame and an outer support block on the side of the bearing shell. This allows the operator to support the device on the side of the wind turbine blade to be tested during measurement, eliminating the need for continuous hand-held operation. This avoids hand vibration during hand-held measurement and further increases the accuracy of the measurement.

[0012] 4. The external linkage hydraulic cylinder of this utility model is provided with a fluid replenishment hole on its side, so that after long-term use, the operator can replenish or replace the hydraulic oil stored inside the external linkage hydraulic cylinder, increasing the convenience of maintenance of this device.
