[0024] specific implementation plan

[0025] The present invention and its specific beneficial effects will be further described in detail below in conjunction with the accompanying drawings.

[0026] like figure 1 , Figure 2a-2d , image 3 As shown, a device for all-round permanent and continuous removal of sediment in the reservoir area, including the diversion channel gate 4, the diversion channel 5, the front gate 6 of the temporary sediment deposition area, the temporary sediment deposition area 7, and the temporary sediment deposition area Area rear gate 8, sand discharge tunnel or channel gate 9, sand discharge tunnel or channel 10. One or more temporary sediment deposition areas 7 (from the previous temporary sediment deposition area 7 or from other temporary sediment deposition areas 7) that are built in the same river channel and whose overall bottom surface is relatively lower than the bottom line 48 of the riverbed at a certain or preset depth. The silt washed...

Abstract

The invention discloses a device for clearing away deposited silt in a storage reservoir region permanently and continuously in all directions. One or more temporary silt deposition regions are constructed in a river channel nearby a water inlet of the storage reservoir region sequentially; the bottom of the temporary silt deposition region is lower than a riverbed plane; one side of the temporarysilt deposition region communicates with a desilting tunnel or channel through a desilting tunnel or channel gate; an outlet of the desilting tunnel or channel is guided into a downstream river channel and/or a permanent silt deposition region constructed downstream through gates correspondingly; a diversion channel is constructed on the other side of the temporary silt deposition region; and gates are constructed at the upstream end and the downstream end of the temporary silt deposition region and the diversion channel and control respective fluid flow time, flow directions and flow rates.Silt which comes by rushing of a water flow and is about to enter the storage reservoir region to be deposited can be subjected to deposition clearing before entering the storage reservoir region permanently and continuously in all directions and in a long-acting manner, and then the relative originally-designed effective life cycles of the storage reservoir region and a water power station can beprolonged indefinitely.

Description

technical field [0001] The invention relates to the technical field of hydroelectric power generation, in particular to a device for comprehensively and permanently removing sediment deposited in an established reservoir area and prolonging its effective service period indefinitely. Background technique [0002] The reservoir areas that have been built at home and abroad (about 90,000 in China alone) have a certain water storage scale and are used for power generation, irrigation, flood storage, or domestic drinking water storage. Due to the difference in sand content and the prolongation of the service cycle year by year, a considerable part of the reservoir area is due to the rapid deposition of sediment and other easily deposited debris. In order to prolong the effective use period of the reservoir area, relevant scientific research institutes and some water conservancy management departments have done a lot of research and developed many technologies such as empty sand d...
