Description

A high-voltage transmission line detonating cord fixing device technical field The present invention relates to overhead transmission line blasting and deicing technical field, be specifically related to a kind of high-voltage transmission line detonating cord Fixtures. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] In some rainy and wet suburban areas, rain and rime often appear on the transmission lines where it is distributed. As well as icing and other conditions, if the rain, rime and icing that have been consolidated on the line will continue to accumulate after a long time increase, and eventually the transmission line will be overstretched, the related circuit components will be worn out, and even the transmission tower will be deformed, unstable and collapsed. The adjacent transmission towers are continuously damaged, causing serious grid damag...

Problems solved by technology

[0003] In some rainy and snowy or humid suburban areas, rime, rime, and ice coating often appear on the distribution lines. If the rime, rime, and ice coating that have solidified on the line have accumulated It will continue to increase, and eventually the transmission line will be overstretched, the relevant circuit components will be worn out, and even the transmission tower will be deformed, unstable and collapsed, and the adjacent transmission tower will be continuously damaged, causing serious damage to the power grid and affecting the economic development of the power transmission place. , social operation and normal life have a major impact

[0004] However, such severe electrical accidents caused by transmission line consolidation are not inevitable

At present, in order to deal with the problem, two methods are generally used for deicing. The first method is that relevant personnel climb on the transmission tower to carry out high-altitude operations, and use deicing tools and corresponding protective measures to manually deicing. This method is the most direct, but During the deicing process, because the transmission lines and transmission towers will be covered with rain and snow, it is very easy to affect the reliability of the safety equipment in the manual deicing process, and it poses a severe test to the life safety of personnel working at heights, and this kind of The labor cost required by the method is relatively expensive; the second is to use some thermal deicing facilities such as thermal deicing vehicles, thermal deicing robots, etc., to use electric energy to generate heat to melt the ice and snow solidification on the transmission line, so that However, this method will be affected by factors such as terrain and icing length. Many large-scale thermal deicing facilities cannot be specifically applied because of the harsh geographical environment such as plateaus, hills or cliffs where overhead transmission lines are located. Moreover, some thermal deicing robots with good performance fail to deice because the internal battery energy storage is not enough to remove the solidification of long ice-coated lines, which wastes a lot of energy. It is not recommended to use them in the current environment of energy shortage.

[0005] At present, there is a method of blasting deicing, which overcomes the defects of the above two methods. It needs to use a fixing device to fix the detonating cord under the high-voltage transmission line. When the ice layer of the high-voltage transmission line reaches the set thickness, Using the detonation index blasting blasting device, using vibration to de-ice, but the inventor found that the current detonating cord fixing device cannot meet the use requirements of high-voltage transmission lines with different diameters, and the distance between the high-voltage transmission line and the detonating cord cannot be adjusted , unable to meet the blasting deicing requirements in complex environments
