Embodiment Construction
[0016] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.
[0017] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

The invention discloses a beak structure and method of an earth wire support of an ultrahigh-voltage direct-current steel transmission tower. The beak structure of the earth wire support of the ultrahigh-voltage direct-current steel transmission tower comprises the earth wire support. The earth wire support is composed of an upper plane main material, a lower plane main material, a horizontal plane oblique material and an end face oblique material. The upper plane main material and the end face oblique material intersect at the upper endpoint of a beak. The end face oblique material and one end of the horizontal plane oblique material intersect at the endpoint of the support. The other end of the horizontal plane oblique material intersects with the upper plane main material. The upper endof the lower plane main material is connected to the lower endpoint of the beak of the horizontal plane main material. A beak supporting arm is connected between the upper endpoint and the lower endpoint of the beak on the same side. A force-transmission oblique material is arranged in a plane formed by the upper endpoints and the lower endpoints of the two beaks. By the adoption of the beak structure, the problem that the stress performance of beaks of an existing earth wire support is poor, and consequentially, the load condition and the service life of the existing earth wire support are affected is solved.
Description
technical field [0001] The invention relates to a bird's beak structure and method for a ground wire support of an UHV direct current transmission tower, and belongs to the technical field of the ground wire support bird's beak structure. Background technique [0002] Electric energy is the most convenient and common energy source in the world. Transmission of electric energy with overhead transmission lines is the basic way of transmission and distribution of electric energy, and its application has a history of more than 100 years. In the case of increased power demand, increased capacity, scattered power sources, and long transmission distances, iron towers have gradually become the preferred type of transmission lines. Therefore, transmission towers are crucial equipment in the process of power transmission. [0003] In the power transmission line project, the cost of the iron tower project accounts for a relatively large proportion of the project cost, generally reachin...
