Reservoir desilting system

Abstract

The invention relates to a reservoir desilting system which comprises a dam, a sediment retaining dam, a sediment discharge pipeline and a sediment pumping ship. The sediment retaining dam is arranged in a reservoir, a flood discharge tunnel and a gate which is used for closing the flood discharge tunnel are arranged on the dam, and a sediment discharge channel is arranged below the flood discharge tunnel; a sediment discharge tunnel and a gate which is used for closing the sediment discharge tunnel are arranged on the sediment retaining dam; one end of the sediment discharge pipeline is connected with the flood discharge tunnel, the other end of the sediment discharge pipeline is arranged at the bottom of the sediment retaining dam, and the sediment discharge pipeline is connected with the sediment pumping ship; an ultrasonic distance measuring instrument which is used for measuring the depth of the reservoir is arranged on the sediment retaining dam. The reservoir desilting system has the advantages that sediment deposited at the bottom of the reservoir all year round can be efficiently removed by the reservoir desilting system, the reservoir desilting system has intelligent functions, energy can be saved, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to a dredging system for a reservoir, which belongs to the field of water conservancy engineering. Background technique [0002] Reservoirs are generally interpreted as "hydraulic engineering structures that hold back flood water and regulate water flow, and can be used for irrigation, power generation, flood control and fish farming." It refers to artificial lakes formed by building dams at the narrow mouths of ravines or rivers . After the reservoir is completed, it can play the roles of flood control, water storage for irrigation, water supply, power generation, and fish farming. [0003] With the development of economy and society, human beings have more and more demands on the development and utilization of rivers, and more and more water conservancy projects are built on rivers. In particular, a considerable number of reservoirs in sandy rivers have lost their normal water storage function due to severe sedimentation. The ...

Problems solved by technology

[0003] With the development of economy and society, human beings have more and more demands on the development and utilization of rivers, and more and more water conservancy projects are built on rivers. In particular, a considerable number of reservoirs in sandy rivers have lost their normal water storage function due to severe sedimentation. The dams and their ancillary buildings built for water storage and profit also lost their functions, resulting in a shortage of resources. Serious waste

[0004] The existing dredging methods for reservoirs mainly use dead storage capacity to retain sand and discharge sand with different density currents. These dredging methods are not effective, and some reservoirs are still simply using manual dredging and dredging, which consumes a lot of manpower. material resources
