Description

Technical Field

[0001] The utility model relates to the field of fault locating equipment, in particular to an optical cable fault locating device. Background Art

[0002] The basic structure of an optical cable is generally composed of several parts, such as a cable core, reinforcing steel wire, filler and sheath. During the use of the optical cable, the optical cable core often breaks, and it is necessary to check the break point for repair. However, since the optical cable is usually long and the cable core is covered with a plastic protective sheath, the break point is difficult to find, and a special fault locating device is needed to detect and locate the fault point.

[0003] According to a portable optical cable fault locating device disclosed in the existing patent document with the publication number CN212514847U, it includes a fault locating seat, an optical cable channel is opened horizontally through the inside of the fault locating seat, a pressure rod channel connected to the optical cable channel is opened through the inside of the fault locating seat and located above the optical cable channel, a pressure rod is inserted into the pressure rod channel, the upper end of the pressure rod is vertically fixed to the pressure plate, and the bottom edge of the pressure plate is fixed to the top surface of the fault locating seat through multiple springs. When the technical solution is in use, the optical cable is inserted into the optical cable channel, so that the iron rotating drum is pressed on the optical cable and the optical cable is pressed tightly, and the optical cable is pulled along the optical cable channel. When the cable core is broken, since there is no cable core support at the break, the iron rotating drum moves down to flatten the optical cable and is adsorbed by a strong magnet, thereby determining the cable core break position. According to the above technical solution, the fault point is detected by rotating the drum, but the solution can only detect the optical cable in a single way when in use, which is inconvenient when in use.

The laser detection mechanism 21 is a prior art, and the specific working principle is the same as the principle inside the comparative document CN218613556U, and the prior art is directly used inside this device.

[0023] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When the device is used, the movable column 2 is moved upward through the fixing plate 3. When the movable column 2 moves upward, the limit ring 11 squeezes the support mechanism 10, and the support mechanism 10 squeezes and contracts to provide a moving distance for the movable column 2. After the movable column 2 moves upward, the fixing frame 13 enters into the inside of the fixing groove 12, so that a certain width is opened between the roller 14 and the drum 19, and the optical cable 20 is placed between the roller 14 and the drum 19.

The diameter of the roller 19 is smaller than the diameter of the roller 14. The roller 19 can detect and locate the optical cable 20 with a small area break.

A beam of detection light is emitted from the far end to measure the stress change on the optical fiber. Combined with the basic data of the geographic information location, the goal of rapid positioning is achieved, and the positioning accuracy of the optical cable fault point is improved. After use, the movable frame 5 is movable to seal the opening 7 to avoid damage to the laser detection mechanism 21 when not in use.
