[0002] At present, the construction of wind power generation in China is in a period of rapid development. As an important form of renewable energy, wind power generation has attracted more and more extensive attention. Fan blades are important components in wind power generation units. Maintaining the integrity of fan blades is the key to ensuring the safe operation of wind power generation units. Most of the existing fan blades are made of fiberglass composite materials. Due to the complexity of their processes and the variability of wind loads, cracks, delamination and other typical defects as well as external damage are inevitable during the manufacturing and operation of the blades, thus affecting the lifespan of the fan blades. Since the lifespan of the fan blades directly affects the total power generation of the wind power generation unit, the performance of the wind turbine blades is very crucial;

The two first telescopic cylinders 9 are respectively located between the four stabilizing components 10.

[0028] Further, as Figure 4As shown in the figure, the stabilizing component 10 includes two second telescopic cylinders 101 distributed front and back. The output ends of the two second telescopic cylinders 101 are fixedly connected together with a fixed block 102. One end of the fixed block 102 away from the second telescopic cylinders 101 is provided with three mounting grooves 103 distributed front and back. On one side of the inner part of the three mounting grooves 103 close to the second telescopic cylinders 101, springs 104 are fixedly connected. On one side of the three springs 104 away from the fixed block 102, column blocks 105 are fixedly connected. On one end of the three column blocks 105 away from the springs 104, rubber balls 106 are fixedly connected. The two second telescopic cylinders 101 are both fixedly connected with the moving seat 6 or the top plate 8. The three column blocks 105 are respectively inserted and connected with the three mounting grooves 103.

[0029] Through the above scheme: the setting of multiple stabilizing components 10 in the device can, during the use of the device, clamp and stabilize the fan blades through the multiple stabilizing components 10, preventing the fan blades from shaking during the detection process and affecting the detection results of the fan blades.

[0030] Further, as Figure 3 shown, the moving seat 6 includes a fixed box 61. Both the front end and the rear end of the fixed box 61 are provided with two moving holes 62 distributed left and right. Inside the two left moving holes 62 and the two right moving holes 62, a shaft rod 63 is movably connected in common.

[0032] Working principle: The present utility model provides a device for detecting the strength of a fan blade. The core of it lies in integrating an innovative stabilizing and pressure measuring mechanism. Specifically, on the top of the movable base and at the bottom of the top plate 8 located above it, two sets of stabilizing components 10 are ingeniously installed. When performing the blade detection task, the user first needs to stably install the fan blade to be detected on the mounting plate 1, and then place the moving seat 6 steadily on the double slide rail 2 system inside the device. Through the remote control interface, the operator can easily command the operation of the device, including precisely controlling the moving seat 6 to slide to the key area where the fan blade is to be detected;

[0033] At this time, the first telescopic cylinder 101 in the four stably arranged stabilizing components 10 starts immediately, driving the rubber ball 106 inside it to flexibly adjust its position with the elastic assistance of the spring 104, so as to achieve all-round and stable clamping of the fan blade. This design ingeniously avoids the test errors caused by the vibration or deviation of the fan blade during the detection process, ensuring the accuracy of the detection results;

[0034] Meanwhile, pressure sensors 11 driven by the second telescopic cylinder 9 are arranged at the top of the moving seat 6 and the bottom of the top plate 8 of this device. This configuration endows the device with high flexibility, allowing users to choose to conduct strength tests on the upper or lower part of the fan blade alone according to the detection requirements, or perform comprehensive detection on both the upper and lower parts simultaneously, thus significantly improving the detection efficiency and the versatility of the device.

[0035] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
