Crawler-type ice guiding structure for river channel in cold region

Abstract

The invention discloses a crawler-type ice guiding structure for a river channel in a cold region. The crawler-type ice guiding structure for the river channel in the cold region is arranged on the downstream side of the ice drainage channel in an inclined mode and has an included angle between a main channel and the ice drainage channel; the crawler-type ice guiding structure for the river channel in the cold region is composed of anchored piles, connecting cables, power drums, auxiliary drums and ice drainage crawler; the anchored piles are arranged on both sides of the main channel, and thepower drums and the auxiliary drums are vertically and equidistantly arranged and connected with each other through the ice drainage crawler in sequence; the ice drainage crawler is arranged on the outer sides of the power drums and the auxiliary drums; the power drums and the auxiliary drums are cylinders, and the power drums and the auxiliary drums are formed by drum float bodies, drum main bodies and drum weights from top to bottom in sequence, and rotating motors are installed in the drum main bodies of the power drums to provide power; drum rotating shafts are arranged in the middle of the auxiliary drums, and the upper ends and the lower ends of the power drums and the auxiliary drums are connected by connecting rods in sequence; and the two sides of the ice guiding structure are connected by two flexible connecting cables and the anchored piles through fixing clamping buckles correspondingly, so as to increase the adaptability of the ice guiding structure to the change of waterlevel.

Description

technical field [0001] The invention relates to ice damage prevention and control measures for rivers and canals in cold regions in winter, in particular to a crawler-type ice guide structure for rivers and canals in cold regions. Background technique [0002] The climate in northern my country is cold in winter, and most of the rivers and channels operate under the ice cover in winter. However, before the ice cover is formed in early winter and after the ice cover breaks up in late winter, a large amount of ice will move with the water flow. When the water flow velocity is high, ice is easy to stagnate, submerge, and accumulate at places such as river canal section mutations, bottom slope mutations, and wading structures (gates, bridges), forming ice plugs or ice dam disasters, blocking the cross-section of the water, reducing the The flow capacity of the section may cause ice flood disasters such as overflow of rivers and canals, which seriously threatens people's lives a...
