The invention discloses a transmission tower vibration characteristic detection device, and relates to the technical field of electric equipment. The device includes an unmanned aerial vehicle and landing gears. A center box is arranged between the two landing gears. A center hole is arranged on the center box. A pushing slot is arranged at each of four side walls of the center hole. One side sliding rail is arranged at each of two sides of the pushing slot. A sliding box is mounted on the side sliding rail. The sliding box is in rotation connection with a lead screw. The lead screw is connected with a rotation motor. The rotation motor is arranged in the center box. A pushing plate is connected to the sliding box. The pushing plate is in contact with a sensor. According to the device, theunmanned aerial vehicle is employed to achieve height increasing, an airbag is utilized to buffer impacts of the unmanned aerial vehicle in approaching an iron tower, and a mechanical mechanism is utilized to implement fixing of an unmanned-aerial-vehicle module. Multiple unmanned-aerial-vehicle modules can be placed at the transmission power tower, and used for detection of multiple places. After detection is completed, the unmanned aerial vehicle can directly fly away from the iron tower. Designing is ingenious, the existing unmanned aerial vehicle is utilized for combination designing, costs are low, and adaptability is high.
Description
technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a vibration characteristic detection device of a power transmission tower. Background technique [0002] The transmission tower line system is the carrier of high-load electric energy transmission and an important lifeline engineering structure. Compared with the usual overhead transmission lines, the lattice transmission tower has the common characteristics of high tower structure, large span, soft overall structure, tower-like structure and long-span structure. In addition to earthquake loads, this structural system is sensitive to environmental loads such as wind, rain, and icing, and is prone to vibration fatigue damage and dynamic collapse damage under extreme conditions. [0003] Chinese patent CN 102494650 provides a tower displacement monitoring system, including a tower displacement monitoring terminal and an underground displacement monitoring terminal...
