Protection and monitoring early warning device for power transmission tower on slope

Abstract

The invention relates to the field of protection and monitoring of power transmission towers on slopes, in particular to a protection and monitoring early warning device system for a power transmission tower on a slope. The system comprises a local geological deformation sensing device, a deformation data processing box, a local safety alarm box, a cable, a thick steel wire used for reinforcing the power transmission tower, and a remote network monitoring terminal. The local geological deformation sensing device comprises a cylindrical steel shell, a resistance type semiconductor strain gaugeand a power supply device, the thick steel wire penetrates through the axis of the local geological deformation sensing device and is fixedly connected with the local geological deformation sensing device, one end of the thick steel wire is connected with the slope, and the other end of the thick steel wire is connected with the power transmission tower; the resistance type semiconductor strain gauge is arranged in an inner cavity of the cylindrical steel shell, and the deformation data processing box comprises a threshold discrimination unit, a wireless transmission unit and a GPRS positioning sensor. When landslide deformation is too large, an alarm is given out in time, and therefore real-time remote monitoring and accident early warning are conducted on the unstable slope where the power transmission tower is located.

Description

technical field [0001] The invention relates to the field of protection and monitoring of transmission towers on slopes, in particular to a protection, monitoring and early warning device system for transmission towers on slopes. Background technique [0002] Transmission towers, as supports for transmission of high-voltage or ultra-high-voltage overhead lines, are widely distributed in flat land or mountainous areas. As towering structures, transmission towers are very sensitive to inclination deformation and have high requirements for uneven foundation settlement. When transmission towers are erected in mountainous areas or even When it is on a slope, due to the influence of wind force, gravity, water, and surface settlement, the slope is unstable or the external force factors such as wind force are too large to cause the collapse of the transmission tower; at the same time, the wind force and the internal components of the transmission tower are loose. Displacement is als...

Problems solved by technology

[0003] The existing transmission tower accident monitoring and early warning technology mainly uses mechanical sensors to inspect and maintain the power tower structure, but the early warning mechanism for disasters caused by slope geological deformation is not perfect, and it mainly relies on manual regular monitoring, which has the disadvantages of untimely early warning and high energy consumption. Disadvantages of time-consuming, labor-intensive and low degree of automation
