Hydraulic rotation steel dam

Abstract

The invention relates to a hydraulic rotation steel dam mainly applied to the field of water retaining and storing in river ways and reservoirs, the field of farm irrigation and the building field of water conservancy projects such as small hydropower stations. The hydraulic rotation steel dam is composed of a plurality of water-retaining face plate units according to the width of a water-retaining surface, each water-retaining face plate is firmly connected to a dam foundation through a bottom shaft and a hinge support, the middle of each bottom shaft is firmly connected with a transmission rod into a whole, the other end of each transmission rod is connected to a hydraulic cylinder, and each hydraulic cylinder is fixed to the dam foundation. By controlling telescoping of the hydraulic cylinders, the bottom shafts and the water-retaining face plates are driven to rotate, and therefore dam erecting and releasing can be realized. The hydraulic rotation steel dam is simple in structure, fast to erect and release, safe, reliable, economical, durable and free of limitation of water quality and regions.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, and more specifically relates to a hydraulic rotating steel 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 ea...

Problems solved by technology

With this structure, during the opening and closing process, the bottom shaft of the steel dam gate is hydraulically driven to drive the dam face plate to rotate. Since the water retaining face plate of the steel dam gate is an integral structure with a relatively large span, the bottom shaft is bulky and the power of the driving device is relatively large. , resulting in high investment; hydraulic drive has very high requirements on the levelness of the bottom shaft and is sensitive to foundation deformation, so it has very high requirements on foundation civil construction and cannot adapt to the settlement of dam foundation

Especially in long-span river courses, it is necessary to build a relay control pump room, which not only blocks water significantly, resulting in poor flood flow, but also makes it difficult to control the hydraulic synchronous lifting of large-span steel dam gates, and the bottom shaft is easy to bend and shift, resulting in Conditions of use are restricted
