Embodiment Construction
[0031] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0032] Such as figure 1 As shown, a damping barrage for blocking super-high ships according to the present invention includes a left tower 1 and a right tower 2, and the left tower 1 and the right tower 2 stand on both sides of the river through unearthed columns 16, respectively. The upper part of the left tower 1 is equipped with a hoisting pulley A3, and the upper part of the right tower 2 is equipped with a hoisting pulley B4. The hoisting pulley A3 and the hoisting pulley B4 are mirror images, and their structures are as follows: Figure 6 As shown, the hoisting pulleys in the prior art can be used, and they are respectively installed above the left tower 1 and the right tower 2 in the manner of the prior art. The left traction...

The invention relates to a damping type overhead warning line for blocking ultrahigh ships. Compared with the prior art, the defect that an existing electric overhead warning line cannot be applied to practice is solved. A left traction line is wound around a lifting pulley A. A right traction line is wound around a lifting pulley B. A middle blocking line is connected between the left traction line and the right traction line. A left blocking line is wound around a fixed pulley A and a lifting pulley C and installed at the intersection of the left traction line and the middle blocking line. A right blocking line is wound around a fixed pulley B and a lifting pulley D and installed at the intersection of the right traction line and the middle blocking line. The other end of the left traction line and the other end of the left blocking line are installed on a mass block assembly A. The other end of the right traction line and the other end of the right blocking line are installed on a mass block assembly B. the ultrahigh ships are prevented from being close to the overhead warning line in a flexible manner, and the ultrahigh ships are blocked outside the safety distance of a cross-river power transmission line technically.
Description
technical field [0001] The invention relates to the technical field of barrages, in particular to a damping barrage for blocking super-high ships. Background technique [0002] Since 2012, there have been many incidents of tripping and outages of cross-river transmission lines caused by the movement of illegal sand mining vessels in the Anhui power grid system, resulting in a very severe security situation for cross-river transmission lines. If similar accidents are not dealt with in time, it is very easy to cause grid disassembly, power plant shutdown, and large-scale power outages. [0003] The 1000kV Huaihe River crossing of the Huaihe-Wuhan Line is part of the 1000kV Huainan-Shanghai UHV power transmission and transformation project. It has the longest distance across the Huaihe River and is known as "the first span of the Huaihe River". On June 28, 2013, before the 1000kV Huaiwu Line was put into operation, the crossing was scraped by an ultra-high sand mining vessel...
