Water conservancy and hydropower station water retaining dam with mud-sand separating function

Abstract

The invention discloses a water conservancy and hydropower station water retaining dam with a mud-sand separating function. The water conservancy and hydropower station water retaining dam comprises awater dam body and a tunnel flow pass structure located in the water dam body. A lifting sluice valve mechanism is mounted at the outlet end of the tunnel flow pass structure. An impurity filter device and a mud-sand separating device are arranged on the outer side surface of the lifting sluice valve mechanism. When the water conservancy and hydropower station water retaining dam with the mud-sand separating function is used for storing water, the tunnel flow pass structure is arranged at the bottom of the water dam body due to sand and mud sediment, mud and sand mixtures can be filtered through the impurity filter device when being discharged out of water outlets corresponding to the tunnel flow pass structure, large-particle impurities mixed in the mixtures are removed, then mud and sand are separated through the mud-sand separating device, water with the impurities removed is then discharged into the water dam body, and the mud and sand are separated for selling or construction purposes.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower, in particular to a water conservancy and hydropower station water retention dam with the function of separating sediment. Background technique [0002] At present, the pollution of urban and rural rivers in my country is very serious, and measures are being taken for large-scale treatment in various places. Among them, the ecological restoration of rivers is the most complicated systematic project in the whole treatment, including sewage interception, river dredging, water purification and river bank vegetation. Clear water, smooth, green banks, beautiful scenery, harmonious coexistence between man and nature, rivers, dams, reservoirs, etc. need to build water conservancy and hydropower station water retention dams with the function of sediment separation. However, in terms of rivers or dams, the corresponding dam body will be used to stop water, store water and control drainage. Fo...

Problems solved by technology

However, the sediment separators used in the river treatment process are all equipped with mixed material inlets and multiple clear liquid and sediment outlets at different heights of the vertical swirling barrels with conical bottoms. Due to the excessive number of outlets, the separation of sediment is not complete; moreover, the sediment discharged from the high position contains too much water, which is not only difficult to handle, but also complicated in equipment, unsatisfactory in effect and large in investment
