Abstract

Technical Field

[0002] Petroleum fiber mainly refers to the fiber technology used in the petroleum industry, especially the fiber sensor technology. Since the petroleum industry often needs to work in harsh environments such as high temperature, high pressure, corrosion and electromagnetic interference, traditional electronic sensors often cannot meet the requirements. Fiber optic sensors have been widely used in the petroleum industry due to their unique advantages, such as anti-electromagnetic interference and ability to work under extreme conditions.
[0003] Fiber tension test is to evaluate the performance of fiber under stress. Tensile test is usually carried out using professional test equipment, including tension sensor and clamp. Tensile sensor is used to measure the force change of fiber, and clamp is used to fix the fiber and ensure it is in a stable state during the test.
[0004] During the test, the fiber sample is hung on the fixture of the test device, which needs to be wear-resistant, corrosion-resistant, heat-resistant and high-precision. Before the test begins, it is necessary to check whether the tensiometer and data logger are working properly. Then gradually increase the load until the required test range is reached, and record the load value shown on the tensiometer. If necessary, the test can be repeated several times to ensure the accuracy of the experimental results. After the test is completed, the load value needs to be gradually reduced.
[0005] However, the clamps in common optical fiber tension testing mechanisms usually use two clamping plates to clamp the optical fiber from both sides for fixation. There is a clamping groove in the middle of the two clamping plates. When clamping the optical fiber, the optical fiber needs to be aligned with the groove, which is easy to clamp off-center. In view of this, the present application proposes an optical fiber tension testing mechanism. Utility Model Content

[0013] Furthermore, the top end of the adjusting screw extends to above the top plate, and a driven gear is fixedly mounted on the top end of the adjusting screw.

[0016] Beneficial effects:
[0017] 1.
