Floating-suspending combined flexible water retaining curtain

Abstract

The invention provides a floating-suspending combined flexible water retaining curtain. The floating-suspending combined flexible water retaining curtain comprises a working floating cabin, a water retaining curtain, a curtain hanging cable, hanging counterweights, a curtain control winch, a floating cabin regulating cable, a floating cabin regulating winch, a silo bottom anchoring cylinder, worktables and an overhauling floating cabin; the hanging counterweights are evenly distributed on the two sides and the bottom of the water retaining curtain; the working floating cabin and the water retaining curtain are arranged in front of the power station water inlet of a power generation dam body section; the silo bottom anchoring cylinder is arranged in the middle of the silo bottom; the worktables are arranged on the dams on the two sides; the curtain control winch and the floating cabin regulating winch are fixed on the worktable; the working floating cabin and the water retaining curtain are positioned and regulated by use of the curtain hanging cable and the floating cabin regulating cable, and single-point control of the curtain and the floating cabin can be realized; the overhauling floating cabin is arranged under the working floating cabin. The floating-suspending combined flexible water retaining curtain has the advantages that the floating structure and the suspending structure are combined, the flexibility of part replacement and control is improved, and the stability and the practicability of buildings in the working process are enhanced.

Description

technical field [0001] The invention relates to hydraulics and hydraulic structures, in particular to a floating-hanging combined flexible water-retaining curtain. Background technique [0002] With the increasing number of high dam reservoir projects, the ecological and environmental problems brought about by such projects have become more and more prominent. Among all kinds of ecological and environmental problems, the deep water low temperature in the high dam reservoir area has the most significant impact on fish habitat. For high dam reservoir projects, the water level in the reservoir area is generally deep (some exceeding 200-300m), which causes a huge difference in temperature between the surface water body and the deep water body in the reservoir area. Generally speaking, there is a certain distance between the water intake of the power station and the top of the dam, so the temperature of the water taken by the power station for power generation is likely to be re...

Problems solved by technology

There are two limitations of the floating structure: 1) The bottom of the water-retaining curtain is fixed to the bottom anchor, and the disassembly and replacement process is very complicated; 2) The top of the air-floating tank is not restricted, and the height of the structure depends on the degree of inflation of each floating tank , for complex water flow environment, it is very dif
