Description

Technical Field

[0001] The invention discloses an optical fiber macrobend detection device, belonging to the technical field of optical fibers. Background Art

[0002] Optical fiber, short for optical fiber, is a thin medium made of glass or plastic. Its main function is to transmit light through the principle of total internal reflection. However, when the optical fiber is installed and forms a bend, if the propagation angle of the light beam when it reaches the boundary of these bends exceeds the critical value, it cannot meet the conditions required for total internal reflection, causing part of the light to escape from the fiber core, thereby causing a loss of transmission power. In order to ensure that the optical fiber can operate normally and maintain its performance, it is usually necessary to perform macrobend detection on it;

[0003] Currently, optical fiber macrobend detection devices are generally composed of an infrared transmitter, a high-precision detector PK2200, and a special ring wheel. The specific operating steps are as follows: first, wind the optical fiber to be tested on the ring wheel to simulate the bending condition in actual use; then, connect the two ends of the optical fiber to the infrared transmitter and the detection instrument PK2200 respectively; finally, start the system for detection. Although this process seems simple and straightforward, there are many challenges in the actual operation process - since the entire bending process is completely dependent on manual labor, it is not only time-consuming and labor-intensive, but it is also more likely to cause problems such as loosening of the optical fiber due to human factors, thereby affecting the accuracy and reliability of the final test results.

[0039] The fixing plate 33 is installed on the front end of the first box body 31. The fixing plate 33 is used to provide a mounting carrier for components such as the driving device, and the fixing part of the driving device connected with the output shaft and the rotating gear 34 is installed on the upper end of the fixing plate 33. The rotating gear 34 is driven to rotate through the driving device. The driving device can use a servo motor 32, and then the rotating gear 34 extending into the arc-shaped groove 13 is rotatably connected to the lower end of the fixing plate 33, and the arc-shaped rack 12 meshing with the rotating gear 34 is set on the front wall inside the arc-shaped groove 13. The arc-shaped rack 12 is used in conjunction with the rotating gear 34 to move components such as the fixing plate 33.

[0040] When in use, firstly, one end of the optical fiber to be detected is fixedly installed with the port of the light source generator 7, and then the other end of the optical fiber to be detected is fixedly installed with the port of the detection instrument 3, and then the servo motor 32 is started to drive the rotating gear 34 to rotate. Since the rotating gear 34 and the arc-shaped rack 12 are meshed with each other, the rotating gear 34 rotates and simultaneously moves along the arc-shaped gear, so that the fixing plate 33, the driving device and the first box body 31 and other components move along the arc-shaped through groove 13, and then the detection instrument 3 is moved to a suitable position, and the optical fiber to be detected is bent under the restriction of the outer end of the fixing cylinder 23, so as to realize rapid bending of the optical fiber to be detected, effectively reduce the detection time and labor intensity, and can mechanically adjust the bending degree, effectively ensuring the accuracy and effect of optical fiber macrobend detection;

[0042] Then start the detection instrument 3 and the light source generator 7. The light source generator 7 will deliver light to the optical fiber to be detected. The light source is delivered to the detection instrument 3 along the bent optical fiber. The detection instrument 3 will detect the input light source and compare and calculate the light source emitted by the light source generator 7 with the light source received by the detection instrument 3 to realize bending loss detection of the optical fiber.

[0044] The fixed part of the lifting device connected to the movable part and the upper end of the movable plate 52 is set on the top of the inside of the function box 5. The movable plate 52 is driven to move up and down through the lifting device. The lifting device can use an electric push rod 51, and four first telescopic rods 53 whose other ends are connected to the top of the inside of the function box 5 are respectively installed at the four corner positions of the upper end of the movable plate 52. The four first telescopic rods 53 are used together to guide the movement of the movable plate 52. Then, a power supply 6 electrically connected to the lifting device, the light source generator 7 and the detection instrument 3 respectively is set on the upper end of the function box 5. The power supply 6 is used to provide electric energy for the lifting device, the light source generator 7 and the detection instrument 3.

[0045] When in use, first start the electric push rod 51, and then drive the movable plate 52 to move downward along the function box 5, so that the four universal wheels 54 move downward, and then the four universal wheels 54 contact the ground and lift the function box 5 and the frame 4 and other components, then use the four universal wheels 54 to move the function box 5 and the frame 4 and other components to the required position, and then use the electric push rod 51 to move the movable plate 52 up and back to its original position, at this time the lower end of the frame 4 contacts the ground, realizing convenient movement of the frame 4 and other components, which is easy to use.

[0048] A plurality of support plates 26 alternately arranged with the trapezoidal blocks 28 are equidistantly arranged between the inner wall of the installation tube 2 and the outer end of the fixed tube 23, and the support plates 26 are used to provide a mounting carrier for the elastic member 25, and a plurality of functional tubes 24 located outside the fixed tube 23 and on the upper side of the support plates 26 are equidistantly installed in the installation tube 2, and the plurality of functional tubes 24 are used in combination to adjust the bending diameter of the optical fiber, and then a plurality of elastic members 25 whose other ends are respectively connected to the upper ends of the plurality of support plates 26 are equidistantly arranged on the lower ends of the functional tubes 24, and the functional tubes 24 are returned to their original positions by the elastic members 25, and the elastic members 25 can be springs;

The movement of the trapezoidal block 28 is guided by the guide rods 281.

[0050] When in use, the rotating shaft 22 is first rotated, and then the large bevel gear 221 is rotated. Since the large bevel gear 221 is meshed with multiple small bevel gears 271, the rotation of the large bevel gear 221 will cause multiple small bevel gears 271 to rotate synchronously, and then multiple first screws 27 are rotated synchronously. Since the first screw 27 is threadedly connected with the trapezoidal block 28, the rotation of the first screw 27 simultaneously moves the trapezoidal block 28 outward, and then the outward inclined surface of the trapezoidal block 28 contacts the inner wall of a functional cylinder 24, so that the functional cylinder 24 moves upward, and the multiple elastic members 25 are stretched, so that the elastic members 25 generate elastic force, and the upper end of the functional cylinder 24 is fitted with the lower end of the top plate 21;
