Description

Technical Field

[0001] The utility model relates to the technical field of power transmission iron tower protection, in particular to an iron tower foundation collapse and inclination correction system. Background Art

[0002] Uneven foundation settlement is the main factor causing the tower to tilt. Most tower tilt and collapse accidents are caused by uneven foundation settlement caused by various reasons. Therefore, it is necessary to detect whether the tower is tilted in time and correct the tilted tower in time. To solve the problem of tower tilt, the invention patent with publication number: CN106638663A (publication date: 2018-11-20) discloses a method for strengthening the foundation of a high-voltage transmission tower in a subsidence area and correcting the tilt of the tower as a whole. However, the following problems often occur when using the method:

[0003] 1) The tower foundation occupies a large area and requires a high amount of reinforced concrete;

[0004] 2) Failure to promptly detect the tilt of the tower caused by the collapse of the tower foundation;

[0005] 3) Manual on-site tilting is required. For remote areas, areas with complex terrain, or due to weather factors and construction difficulties, untimely repairs may cause the tower to collapse;

[0006] 4) On-site manual processing requires the installation of guy wires to prevent tipping, which increases the workload;

[0007] 5) If the jacking mechanism is used to lift the foundation of the joint unit, improper operation may cause the tower to fall;

[0008] 6) On-site workers may suffer from unexpected accidents that may cause personal injury;

[0009] 7) After lifting to the predetermined position, the foundation needs to be backfilled, which may cause the tower to become unbalanced again. Utility Model Content

[0042] Specific:

[0043] An iron tower foundation 3 is buried under the ground 1, and a reinforcing fixture 4 is provided to fix the bottom of the screw rod 5 so that it does not loosen.

[0044] A safety cap 14 is provided on the top of the screw upper part 13 to prevent the adjusting nut 11 from lifting the bracket 12 and detaching from the screw upper part 13. A rigid dust cover 21 is provided on the bracket 12, and a flexible dust cover 22 is provided between the adjusting nut 11 and the tower foundation 3 to ensure the cleanliness of the screw upper part 13.

[0049] When the adjusting nut 11 compresses the flexible dust cover 22 too tight, the current of the motor 10 is abnormal, and the motor power control switch (motor power intelligent control switch) 17 automatically trips and sends data to the monitoring personnel to ensure that the adjusting nut 11 does not contact the tower foundation 3, thereby ensuring the safety of the 2 towers.

[0050] In daily monitoring and intelligent adjustment processing, the balance control device 20 and the motor power control switch 17 send data to the monitoring personnel in a timely manner to facilitate remote monitoring of the safety of the iron tower 2.
