Description

Technical Field

[0001] The utility model relates to the technical field of power pole towers, in particular to a low-profile power cable pole tower for mountainous areas. Background Art

[0002] As an important part of the power transmission system, the stability and service life of power cable towers directly affect the operation of the entire power system. Most traditional power cable towers are designed to be high, which is inconvenient to transport, especially in mountainous areas, where it is difficult to use large vehicles to transport power cable towers.

[0003] The patent with publication number CN215671429U discloses a power pole tower for power transmission engineering, including a base, a base rod threadedly mounted on the upper surface of the base, a support leg movably mounted on the outer surface of the base, a pull ring fixedly mounted on one end of the support leg, a fixed plate with holes fixedly mounted on the upper surface of the base, a steel wire rope is arranged between the fixed plate with holes and the pull ring, a connecting rod is arranged on the upper surface of the base rod, and a mounting rod is arranged on the upper surface of the connecting rod. The power pole tower for power transmission engineering described in the utility model can store the support legs during transportation, which is convenient for the transportation of equipment, reduces the volume of the transportation vehicle, and is convenient for the transportation vehicle to travel in mountainous areas. The support legs can also be unfolded during use to increase the contact area between the base and the ground and improve the stability of the base. The verticality calibration of the equipment is completed through the cooperation of the steel wire rope and the fixed plate with holes, so as to achieve the purpose of adjusting the verticality and increasing the stability of the base.

[0004] Although the above-mentioned prior art can store the supporting legs during transportation, which is convenient for the transportation of equipment, reduces the volume of the transport vehicle, and facilitates the transportation vehicle to travel in mountainous areas, the connection positions of the base pole and the connecting rod, and the connecting rod and the mounting rod all require the use of a large number of connecting studs and nuts for fixing, which is not convenient for workers to quickly assemble the power pole tower. In view of this, we propose a low-profile power cable pole tower for mountainous areas. Utility Model Content
