Floating object stopping facility

Abstract

The invention discloses a floating object stopping facility which comprises a main rope floating object stopping device and a pull anchor device. The main rope floating object stopping device comprises main rope anchoring pieces, a floating object stopping raft body and main rope steel wire ropes. The two ends of the floating object stopping raft body are fixed to the main rope anchoring pieces through the main rope steel wire ropes. The pull anchor device comprises pull anchor anchoring pieces and pull anchor steel wire ropes. The main rope anchoring pieces and the pull anchor anchoring pieces are buried in a bank or a dam. One end of each pull anchor steel wire rope is fixed to the corresponding pull anchor anchoring piece, and the other end of each pull anchor steel wire rope is connected to the floating object stopping raft body. The floating object stopping facility is structurally characterized in that one section in the floating object stopping raft body is of a U-shaped frame structure, and an opening of the U-shaped frame structure faces upwards. The U-shaped frame structure determines navigation clear width and navigation water depth according to relevant regulations andhas sufficient self-floating, anti-bending and anti-torque capacity, and upstream and downstream vessels can smoothly pass. By means of the floating object stopping facility, the stopping of floatingobjects in the whole section of a river, the safe and smooth passage of the upstream and downstream vessels and the safe and convenient floating object clearing work can be realized.

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;
