a floating device

Abstract

The invention discloses a drift arresting facility, which comprises a main rope drift arresting device and an anchor pulling device. The end is fixed on the main cable anchor by the main cable steel wire rope; the anchor pull device includes a pull anchor anchor and a pull anchor steel wire rope, and the main cable anchor and the pull anchor anchor are buried on the river bank or dam, and the pull anchor One end of the anchor wire rope is fixed on the pull anchor anchor, and the other end is connected to the floating block body. Its structural feature is that a section of the drift arresting body is set as a U-shaped frame structure, wherein the opening of the U-shaped frame structure faces upward. The U-shaped frame structure determines the navigable clear width and navigable water depth according to relevant specifications, and has sufficient self-floating, bending and torsion resistance capabilities, so that upstream and downstream ships can only pass smoothly. The invention can realize the interception of floating objects in the whole section of the river, safe and smooth passage of upstream and downstream ships, and safe and convenient drift cleaning work.

Description

technical field [0001] The invention relates to the field of hydroelectric power generation and shipping, in particular to a facility capable of intercepting floating objects on the reservoir area of ​​a hydropower station or on the full section of a river and allowing ships to pass smoothly. Background technique [0002] For large-scale hydropower station reservoir areas, the submerged area is wide and the vegetation is relatively poor. In addition, there are a lot of production and domestic waste generated by residents on both sides of the strait. Various production and domestic waste will enter the reservoir with the water flow, resulting in many floating objects all year round. affect the ecology of the reservoir area. At present, trash racks are used in front of the water inlet of hydropower stations to intercept floating objects. However, when there are many floating objects, the trash racks at the water inlet of the unit will be blocked. The safe water level differen...

AI Technical Summary

Problems solved by technology

[0003] (1) The drift barrages in the reservoir area of ​​the hydropower station are mainly to prevent a large amount of dirt from accumulating in front of the trash rack, to ensure the safety of the trash rack operation and the efficiency of power generation. During flood discharge, a large amount of floating objects will be discharged downstream along with the flood discharge, causing serious damage to the downstream river environment

[0004] (2) A small number of drift blocking facilities are arranged across the reservoir area or river, but this arrangement space separates the upstream and downstream waterways and cannot meet the navigation requirements

[0005] (3) In order to reduce the tension of the main cable of the large-span drift-stopping facility, an anchor device will be installed on the drift-stopping body, but the sinking depth of the anchor wire rope varies along the length direction, and is different from the Its own tension is closely related, and there is a large uncertainty, which makes it impossible for the cleaning ship to carry out safe cleaning operations in front of the drift blocking facilities

[0007] (1) It is necessary to design a set of floating structures that can not only transmit the tension load of the drift arresting body, but also realize navigation in the middle of the drift arresting facilities. At present, this structure is still blank in the industry;
