Problems solved by technology

[0003] However, when a flood occurs and the dam is pushed down or the dam needs to be removed, due to the large water level difference between the upstream and downstream, when the dam is removed, flood disasters are very likely to occur, which will affect the downstream terrain, plants, animals, residents, etc. cause a huge impact, and therefore, there is a huge security factor

Embodiment Construction

[0022] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0023] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0024] Figure 1 to Figure 2 A schematic structural view of a flood control weir according to a preferred embodiment of the present invention is shown. Such as figure 1 As shown, the main dam 1 straddles the river, and the height of the main dam 1 is generally 100-170m; the flood control weir includes: the foundation dam 2, the gate 3 and the driving device; the foundation dam 2 straddles the upstream of the main dam 1, s...

Abstract

The invention discloses a flood control weir. The weir comprises a main dam stretching across a river and further comprises a base dam, a gate and a driving device, wherein the base dam stretches across the upstream position of the main dam, and the base dam is lower than the main dam; the gate is rotationally arranged at the upper end of the base dam; the driving device is connected with the gate and is used for driving the gate to rotate towards the upper side of the base dam or the lower side of the base dam. With the adoption of the weir, the base dam is arranged above the main dam, and when the main dam is dismounted, the base dam can intercept a certain amount of water flow, so that flood influencing the downstream position is avoided; besides, the base dam is lower than the main dam, and thus ship sailing can be guaranteed.

Description

technical field [0001] The invention relates to the field of flood control supports, in particular to a flood control weir. Background technique [0002] The representative form of a dam as a water-retaining structure is called a dam. It can be divided into earth dam, gravity dam, concrete face rockfill dam, arch dam, etc. Dams are the main backwater structures in hydropower stations. The function is to raise the water level of the river and form an upstream regulating reservoir. The height of the dam depends on the topography, geological conditions, submerged range, population migration, the relationship between the upstream and downstream cascade hydropower stations, and kinetic energy indicators. As of 1989, the height of the highest hydropower dam in mainland China was 178 meters, and the height of the highest dam in the world was 325 meters (earth-rock dam). [0003] However, when a flood occurs and the dam is pushed down or the dam needs to be removed, due to the l...
