Problems solved by technology

This dam erects and collapses quickly, and basically does not block water, but its structural force is unscientific, resulting in a bulky bottom shaft, and the cost is very high. If the span of the steel dam is large, the bottom shaft is easy to bend and shift, resulting in The conditions are limited, so it is not widely used in actual engineering

Embodiment Construction

[0032] In order to understand the technical solution of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0033] see figure 1 — Figure 12 , the water blocking panel 1 is connected to the hinge support 9 through the bottom shaft 8, the hinge support 9 is firmly welded on the steel plate, and the steel plate is firmly welded to the steel cage 10 buried in the dam foundation, thereby fixing the water blocking panel 1 on the dam foundation The back of the water blocking panel 1 is connected with transmission support rods 2, which are arranged in a row at equal distances. The lower end of the transmission support rods 2 is connected to the movable pulley block 5, and the fixed pulley block 4 is installed on the upper end of the dam foundation. forward and reverse to realize dam erection and dam collapse; when the water retaining panel 1 rotates to the predetermined water retaining level, the ...

Abstract

The invention relates to a cable traction reversed-V-shaped water retaining dam. The cable traction reversed-V-shaped water retaining dam is mainly applied to the hydraulic engineering construction field of water retention and storage of watercourses and reservoirs, farm irrigation, small hydropower stations and the like. A water retaining panel (1) of the water retaining dam is firmly connected to a dam foundation by a bottom shaft (8) through a hinge pedestal (9); a row of transmission supporting rods (2) are arranged on the back side of the water retaining panel (1) at equal intervals, connected into a whole through steel plate profiles and locked through a clamping device (11) to form a stable triangle supporting structure. A power device of the cable traction reversed-V-shaped water retaining dam is composed of a cable (7), a pulley block, the transmission supporting rods (2), a winch and the like; the pulley block is connected to the transmission supporting rods (2) and the dam foundation and are rotated positively and negatively through the winch, and therefore the dam erection and dam dropping are achieved. The cable traction reversed-V-shaped water retaining dam is simple in structure, fast in damp dropping and dam erection, safe, reliable, economical, durable and not limited by water quality or territory.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, and more specifically relates to a cable-drawn gable dam. Background technique [0002] With the development of human beings, water resources are becoming more and more tense. In order to make full use of water resources, dams are usually built in river courses, not only to achieve the purpose of water retention and storage, but also not to affect flood control safety, so dams are widely used. The dams currently used in engineering construction include automatic flap dams, rubber dams, and steel dams. [0003] The automatic flap dam has a row of pillar piers in the river channel, and water blocking panels are arranged between the pillar piers. It has the advantages of low cost, convenient operation and management, etc., but there are many problems in the automatic flap dam, mainly including: first, water blocking , cannot withstand the impact of severe floods; second, it is easy to b...
