Problems solved by technology

The idea that seasonal water conservancy projects and dispatching methods can completely eradicate the disadvantages of water conservancy projects is realistic, and the social benefits produced cannot be calculated in money; but there is a problem: the cost of power generation of seasonal water conservancy projects is higher than that of The power generation cost of conventional water conservancy projects is 1.5 to 3 times, causing hydropower operators to give up the seasonal water conservancy projects. This problem needs the supervision and support of the state to solve

specific Embodiment approach 2

[0050] The specific implementation of lake-type seasonal water control projects and plain-type reservoir seasonal water control projects.

[0051] The specific implementation methods of the lake-type seasonal water control hub and the flat-type reservoir seasonal water control hub are the same.

[0052] Due to the discharge of clear water from the Three Gorges Reservoir on the Yangtze River, the elevation of the middle and lower reaches of the Yangtze River has dropped, leading to a decrease in the water level of the river; the drop in water level has led to a drop in the water levels of Dongting Lake and Poyang Lake, and the two lakes have lost their function as lakes during dry periods; the northern part of Dongting Lake may develop into a new drought The area of ​​the corridor; on the shore of Poyang Lake, there is a grassland scenery in front of you. The original lake surface has disappeared, replaced by dry and cracked riverbeds and dense grassland; seasonal water conserva...

Abstract

The invention discloses a seasonal hydro-junction with a high environmental requirement. The seasonal hydro-junction solves the technical problem of the main defect of the hydro-junction, and thoroughly solves the four problems of reservoir area sediment accumulation, reducing of sediment in front of a reservoir, reservoir area water quality deterioration and fish migration recovery. According to the technical scheme, from the last flood period to the last drought period of the next year, the seasonal hydro-junction keeps the normal high water level and achieves impounding functions; and from the last drought period to the last flood period, all water gates of the seasonal hydro-junction are opened, all the impounding functions are stopped, and a riverway returns to a natural state.

Description

Technical field: [0001] The invention relates to water conservancy buildings, in particular to a novel water conservancy hub. Background technique: [0002] The water conservancy project is to meet the needs of various water conservancy projects, but there are also water conservancy disadvantages at the same time. The main water conservancy disadvantages are: 1. It causes the problem of sediment accumulation in the reservoir area. But the effect is not great; 2. The water quality in the reservoir area deteriorates, the water flow in the reservoir area slows down, and part of the water in the stagnant reservoir flows slowly, resulting in deterioration of water quality; 3. The impact on the downstream river channel, due to the decrease in the sediment content of the drainage, the riverbed in the downstream direction Severely eroded by erosion; 4. Blocking fish migration channels, the dam of the water conservancy project hinders fish migration. Retrieving all the prior art of ...
