Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, and more specifically, to a transmission line inspection device. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. Since the transmission line is exposed to the natural environment for a long time, the sag will change to a certain extent, and the sag needs to be detected to ensure the safe operation of the transmission line. At present, the sag monitoring of transmission lines mainly adopts the manual inspection method, but the manual detection method is inefficient and the accuracy is not very high.

[0003] In order to solve the above problems, the utility model with announcement number CN212011917U discloses an overhead transmission line inspection device. When in use, the distance measuring device is hung on the overhead transmission line. A tilt sensor is set to sense whether the main body of the distance measuring device is in a parallel state to ensure that the main body of the distance measuring device can be at the center point of the arc sag, so as to improve the measurement accuracy; when the main body of the distance measuring device is at the center point of the arc sag, a microwave sensor set downward is started to measure the distance between the main body of the distance measuring device and the ground or the obstacle below, so as to obtain the distance between the lowest point of the wire and the ground or the obstacle below.

[0004] When the above-mentioned overhead transmission line inspection device is actually used, since different transmission lines may have different specifications and sizes, the inspection device may need to be replaced and adjusted for different transmission lines, which increases the complexity of the staff's work, wastes the staff's time, and reduces the efficiency of the inspection.
