Water conservancy and hydropower station water retaining dam

Abstract

The invention discloses a water conservancy and hydropower station water retaining dam which comprises a dam body and a tunnel runner structure located in the dam body, a lifting gate valve mechanismis installed at an outlet end of the tunnel runner structure, and a sundry filtering device and a mud and sand separating device are arranged on the outer side face of the lifting gate valve mechanism. When the water conservancy and hydropower station water retaining dam is used for storing water, sand and mud precipitate, a tunnel runner structure is arranged at the bottom of the dam, when the mud and sand mixture is discharged through the corresponding water outlet of the tunnel runner structure, the mud and sand mixture can be filtered through the impurity filtering device to remove large-particle sundries mixed in the mud and sand mixture, then mud and sand are separated through the mud and sand separating device, water with impurities removed is discharged into the dam, and mud and sand are separated for treatment, selling or construction utilization.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower, in particular to a water retaining dam of a water conservancy and hydropower station. 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 dams. However, in terms of rivers or dams, the corresponding dam body will be used to stop water, store water and control drainage. For the existing dam structure, the way that the dam body can be dumped is mostly used for drainage, bu...

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

In addition, for the actual sediment separation operation, if there is no monitoring system, it will inevitably bring a lot of inconvenience to the specific operation, so it is necessary to equip the corresponding monitoring system on the sediment separation device to improve its operation
