Problems solved by technology
[0002] According to the statistics of China Electric Power Corporation, as of the first quarter of 2020, the loop length of transmission lines of 220 kV and above is 834,366 kilometers, and the length of transmission lines is increasing year by year, and the scale is also expanding. The total number of service towers of 220 kV and above in the country is about 1.92 million bases. The design life of transmission towers is generally calculated on the basis of 40 years, and the transmission towers built in the early stage are already at the end of their life or in a state of overdue service. With the passage of time, a large number of transmission towers with overdue service will be produced every year. The overall dismantling and replacement of overdue service towers will cost a lot of money, and if they continue to serve, there will be safety hazards

Embodiment Construction
[0043]The technical solutions of the present invention will be described below by way of specific embodiments. Obviously, the described embodiments are merely the embodiments of the invention, not all of the embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention without all other embodiments obtained without creative labor.
[0044]Such asFigure 1-14 As shown, the method for transmitting the electricity tower structure is used, including the following steps:
[0045]Step 1, select the degree of parameter variables to screen the degree of damage of the tower structure:
[0046]The damage stiffness of the transmission tower structure is changed. The quality and overall damping parameters do not change. When the stiffness of the structural member changes, the inherent frequency or vibration type of the overall structural member is changed, and the appropriate parameter variation is selected according t...

The invention relates to the technical field of transmission tower structural members, in particular to a method for discriminating damage of a structural part of a power transmission tower, which comprises the following steps: 1, selecting a parameter variable degree to discriminate the damage degree of a tower structural part; 2, discriminating the damage of the structural part of the power transmission tower; 3, according to the damage condition of the structural part of the power transmission tower in the step 2, conducting reinforcement or replacement; whether the iron tower meets the continuous service condition or not is judged, accurate positioning and damage degree judgment are conducted on the damaged iron tower structural part, and it is determined that the damaged power transmission iron tower is reinforced or replaced with a new iron tower.
Description
Technical field[0001]The present invention relates to the technical field of transmission tower structural members, and in particular to a method for transmitting a transmission tower structural member damage screening method.Background technique[0002]According to China Power Company Statistics, the length of 220 kV and above transmission line is 834366 kilometers in the first quarter of 2020, and the length of the transmission line has increased year by year. The scale is constantly expanding, according to the 2.3-based transmission of the electric iron tower according to the transmission line per kilometer transmission line. The total number of tower rail towers in the country is about 1.92 million, and the design life of the transmission tower is generally calculated 40 years, while the early construction of the electricity tower is already in the end of life or the overtime service, and because China's power transmission tower is huge, Over time, a large amount of over-term serv...
