Electric power line external-damage-preventive intelligent monitoring system

Abstract

The invention discloses an electric power line external-damage-preventive intelligent monitoring system, which comprises a nearly electric alarm sensor. The nearly electric alarm sensor is disposed on an operation moving arm of a large machine, is connected with an nearly electric alarm device and is further connected with a radar range unit disposed on the operation moving arm of the large machine, and the radar range unit is connected with a protecting device capable of leading the large machine to stop operation. The electric power line external-damage-preventive intelligent monitoring system is reasonable in structure, operation conditions of the construction machine in a power facility protecting area can be controlled in real time, effective safety monitoring is realized, and accidents are effectively prevented.

Description

technical field [0001] The invention relates to an intelligent monitoring system for preventing external breakage of power lines. Background technique [0002] With the rapid development of the economy, infrastructure construction is in full swing everywhere, and large machinery (cranes, tower cranes, cement pump trucks, etc.) can be seen everywhere in various engineering constructions. Some large-scale machinery is close to high-voltage lines or constructed offline. Due to the safety knowledge and safety awareness of a small number of construction workers, it is difficult to effectively control the safety distance between large-scale machinery and high-voltage lines, and accidents such as discharge and line collision are prone to occur and cause large-scale Power outages not only cause losses to power companies, but also affect the power consumption of factories and residents around the construction site. Because these machines are mobile and highly mobile, it is difficult...

AI Technical Summary

Problems solved by technology

Therefore, the anti-breakout cannot achieve full coverage, and there are gaps in safety precautions, so breakout accidents still occur frequently

[0005] The appearance of large machinery near power lines is random and irregular. It is generally difficult to rely on large machinery drivers and operators to consciously avoid high-voltage lines. Large machinery drivers and operators are required to actively notify the information of entering the power protection area. It is even more difficult to protect the personnel of electric facilities

Therefore, in many cases, our power facility protection personnel cannot obtain timely information on large machinery entering the power protection area, and cannot conduct timely management and control

[0006] According to the experience of external damage accidents caused by large machinery such as cranes, tower cranes, and cement pump trucks in the power system for many years, most of the large machinery does not have the function of feeding back the alarm signal to the driver or operator before the large machinery approaches the power line. The above-mentioned alarm signal device has appeared, but there is no forced stop (braking) device, and it is impossible to alarm the protector of the electric power facility in the distance. At the same time, it cannot meet the accurate start under various voltage environments, and does not really play a mandatory protective isolation The role of measures cannot fundamentally prevent accidents where construction machinery touches power facilities
