Description

Technical Field

[0001] The utility model belongs to the technical field of hydropower and water conservancy engineering, and in particular relates to an ecological flow discharge structure during the period of water storage under a sluice gate. Background Art

[0002] At present, in the construction of hydropower and water conservancy projects, in order to maintain the downstream ecological environment and the ecological balance of downstream biological survival, the requirements for downstream ecological flow discharge are required to be met at any time of construction. The water retaining dams of hydropower and water conservancy projects are often built in high mountain narrow valleys, with strong mountains on both sides. The discharge structures during the construction period and some permanent operation periods generally adopt underground shelter structures. In addition, the bedload in the river water in the high mountain canyon area is generally rich, and the scouring and erosion of the discharge structures are also very serious, which seriously affects the operation safety of the discharge structures. Therefore, the layout of the discharge structures and ecological flow discharge structures must consider the influence of bedload. In addition, since the ecological flow discharge structure is generally the last low-elevation water supply channel for supplying water to the downstream during the water storage period, the layout elevation is often low. In order to raise the water level to the next-level discharge structure to realize relay water supply, the gate for regulating water supply is designed as an arc gate to achieve partial opening, and the arc gate is always closed before the water storage. Since the discharge flow of the early discharge structures is often large, in order to prevent the downstream backwater from flooding the arc gate support hinge structure, it is necessary to arrange a flat gate on the downstream side of the arc gate to block water. However, the flat gate, arc gate and the surrounding area of ​​the gate chamber structure may seep water, and the water supply chamber structure is generally small in scale and volume. In addition, the operation period of the early discharge structures is generally several years. If no measures are taken, the arc gate support hinge structure will inevitably be flooded, which will affect the use of the arc gate structure and even cause the arc gate to fail. Therefore, during the operation of the early discharge structures, the design generally requires real-time monitoring, and the water in the water supply chamber must be pumped out before flooding the arc gate support hinge. This work needs to continue for several years, which not only increases the number of on-site management personnel and pumping costs, but also increases the difficulty of on-site management and operation;

[0003] After checking, the public (announcement) number: CN208088251U discloses the ecological flow discharge structure during the period of water storage under the sluice gate. This technology discloses "arranged side by side with the early water discharge tunnel structure, bypassing the early water discharge tunnel lock chamber, diverting water from upstream to downstream during the early water discharge tunnel sluice gate and reservoir water storage, raising the water level to store water while meeting the ecological flow discharge and other technical solutions; in the early water discharge tunnel operation period, the upstream and downstream water retaining gates are in a closed state; in the water discharge stage of the ecological flow discharge structure, the upstream and downstream water retaining gates are fully opened; in the stage of closing the ecological flow discharge structure, the upstream and downstream water retaining gates are successively closed" and other technical effects;

[0004] However, this kind of river flow contains a lot of sediment. When the gate body is used to block water, the sediment will accumulate and stick to the surface of the gate body. When the gate is opened, the weight of the gate will increase, resulting in an overload of the output electrical load, and the surface of the gate body will be corroded, reducing the life of the gate body.

[0005] In order to solve the above problems, this application proposes an ecological flow release structure during the period of water storage. Utility Model Content
