Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] A prefabricated dynamic ice guide structure for river canals in cold regions, such as figure 1 As shown in , it is obliquely arranged on the downstream side of the ice discharge channel, and has a certain angle with the main channel. Such as figure 2 and image 3 As shown, the ice guide structure is composed of a drum float 1, a drum body 2, a drum weight 3, a drum shaft 4, a rotating motor 5, a connecting rod 6, a transmission chain 7, a connecting cable 8, a fixing buckle 9, and an anchor pile 10. . The drum floating body 1, the drum main body 2 and the drum ballast 3 form the basic structure of the auxiliary drum and the driving drum. There is a through hole in the mid...

The invention discloses a prefabricated dynamic ice guiding structure for a river channel in a cold region. The prefabricated dynamic ice guiding structure for the river channel in the cold region isarranged on the downstream side of an ice drainage channel in an inclined mode and has an included angle between a main channel and the ice drainage channel, and is composed of anchored piles, connecting cables, power drums, auxiliary drums and transmission chains; both the power drums and the auxiliary drums are composed of drum floating bodies, drum main bodies and drum weights which are connected in sequence from top to bottom, rotating motors are arranged in the drum main bodies of the power drums; through holes are formed in the middle parts of the auxiliary drums, and the auxiliary drumsrotate freely with rotating shafts of the drums as axes; at least one power drum is arranged; and the power drums and the auxiliary drums and the auxiliary drums and the auxiliary drums are connectedwith each other by connecting rods in sequence, and transmission chains are arranged between the power drums and the auxiliary drums for transferring the power of the rotating motors in the power drums to the auxiliary drums. According to the prefabricated dynamic ice guiding structure for the river channel in the cold region, the two sides of the ice guiding structure are connected with the anchored piles located on the shore through the flexible connecting cables and fixing clamping buckles correspondingly.
Description
technical field [0001] The invention relates to the field of ice damage prevention and control measures for rivers and canals in cold regions for water transportation in winter, in particular to an assembled dynamic 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) to form 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,...
