Problems solved by technology

Although this method can alleviate or temporarily solve the phenomenon of pulling up electric poles in areas with severe frost heave to a certain extent, it cannot fundamentally or long-term solve this problem, and requires a lot of manpower and financial resources every year, and the implementation effect is limited
[0005] In summary, the existing technical solutions to the problem of pulling up electric poles still have problems such as low efficiency, high cost, and poor effect. Therefore, a new structure for preventing electric poles from being pulled up in areas with severe soil frost heaving is urgently needed. In order to better solve the problem of seriously endangering the safety of the power grid caused by the pulling of the utility pole

Abstract

The invention relates to a transmission telegraph pole pull-up preventing structure with a reset function. The structure comprises a telegraph pole, a drag reduction layer, an annular cover and a reset device; the telegraph pole is vertically arranged, the reset device is arranged at the bottom end of the telegraph pole, the annular cover is arranged on the upper portion of the reset device, an acute angle is formed between the conical tip end of the annular cover and the telegraph pole, the conical tip end of the annular cover is fixedly connected with the telegraph pole, and the drag reduction layer is arranged on the surface of a pole root of the telegraph pole; the reset device is composed of tires and hubs, the tires and the hubs are installed in a matched mode and are horizontally placed, the bottommost end of the telegraph pole is fixedly connected with the hub at the uppermost layer, and the other end of the annular cover is also fixedly connected with the hub at the uppermostlayer. According to the structure, by adopting the acute angle connection arrangement between the upper end of the annular cover and the telegraph pole, the pull-up acting force of soil frost heavingon the telegraph pole is converted into the vertically-downward acting force, so that the pull-up resistance of the telegraph pole is increased, and the problem that the telegraph pole is pulled up due to soil frost heaving can be well solved.

Description

technical field [0001] The invention belongs to the technical field of pulling up electric poles, and in particular relates to a structure for preventing pulling up of power transmission poles with a reset function. Background technique [0002] Taking the Genhe area as an example, because the area is located in the Daxinganling forest area, it has many rainy weather, high latitude, and little sunshine, and the power transmission and distribution lines of the Genhe power supply company were mostly built in the 1960s, and the power grid system was changed from the forestry system at that time. Internally built by itself, it is divided into three voltage levels of 110KV, 66KV and 10KV. In addition to the structural design of the line itself and the age of construction, most of the pole foundations are located in the swampy forest area, with high soil moisture content and severe soil frost heave. [0003] Soil heaving and the existence of a certain thickness of frozen soil lay...
