[0027] By setting the heating element 6, when testing the blade 4 to be tested, the blade 4 to be tested can be installed on the output end of the driving motor 3, and the tension value of the blade 4 to be tested can be obtained by testing the tension when the driving motor 3 rotates. During the test, the driving motor 3 is started to drive the blade 4 to be tested to rotate and generate tension, and the tension of the driving motor 3 is tested by using a motor tension tester. The code generated by the motor library software is converted to generate a tension-speed curve, that is, the tension value of the blade 4 to be tested is tested.

[0028] like Figure 1-Figure 5As shown, the wind simulation component includes a first clamping ring 7 fixedly connected to the inner wall of the test cylinder 1, and a plurality of limiting holes 8 are provided on the first clamping ring 7. The inner wall of the test cylinder 1 is also fixedly connected to a second clamping ring 9, and a moving groove 10 is provided on the second clamping ring 9.

At the same time, the position of the fan 13 can be adjusted to judge the influence of wind forces in different wind directions on the tension value of the blade 4 to be tested. When adjusting the position of the fan 13, the lifting rod 17 can be pulled to drive the limit rod 14 and the block 19 to move upward. At this time, the limit spring 16 is in a stretched state, so that the block 19 and the limit rod 14 leave the limit hole 8.

[0030] like Figure 2 As shown, a handle 18 is fixedly connected to one side of the fan 13, and a plurality of anti-slip grooves are arranged on the handle 18. The handle 18 is made of plastic material. When the user adjusts the position of the fan 13, the handle 18 can be used as a fulcrum to facilitate the movement of the fan 13, the fixed block 12 and the slider 11. The anti-slip groove can increase the friction between the user's hand and the handle 18 to avoid slipping when holding the handle 18.

[0032] like Figure 4 As shown, the lifting rod 17 is in a straight line structure, and the materials of the limiting rod 14, the lifting rod 17 and the clamping block 19 are all metal materials. The straight line structure is convenient for pulling up the lifting rod 17, and stainless steel is preferably used, which has good corrosion resistance and hardness, thereby improving the service life of the limiting rod 14, the lifting rod 17 and the clamping block 19.

The heating elements 6 are in a semicircular structure, which fits more closely to the inner wall of the mounting plate 5. The heating elements 6 are evenly distributed, so that the temperature in the space of the test tube 1 can rise evenly when the heating elements 6 are working, so that the ambient temperature of the blade 4 to be tested is always on the same temperature line, avoiding measurement errors caused by uneven distribution of the temperature line.
