Tube bundle-type natural water diversion device and water diversion method for generating electricity

Abstract

The invention provides a tube bundle-type natural water diversion device and a water diversion method for generating electricity. The water diversion device comprises a pressurized water delivery tube bundle arranged along the natural grade of a riverbed, and the water outlet of the tube bundle is communicated with the water inlet of a water turbine; the water inlet of the tube bundle is communicated with the diversion well of a water diversion point arranged on the riverbed or by a river bank. Natural water diversion can be completed without damming up, and the water turbine is rotated to obtain mechanical energy under the state of reserving the ecological environment of the original river by utilizing pressurized water formed in the tube bundle by part of water flow; then a generator is driven to rotate to convert the mechanical energy into electric energy, thereby generating electricity. The problems that the prior art has big occupation area, high amount of capital invested and long construction time and creates serious influence on environment, hydroecology, natural landscapes and the like are fundamentally solved while waterpower resources are sufficiently utilized to provide sustainably developed electric energy to human. The invention has investment saving and high construction speed and can carry out natural water diversion to generate electricity according to circumstances.

Description

technical field [0001] The invention relates to a water diversion device, in particular to a tube bundle type natural water diversion device and a water diversion method for power generation, belonging to the technical field of hydroelectric power generation. Background technique [0002] Hydropower generation is to increase the water level by building dams or other means to use the energy generated by the drop between the high and low water levels to make the water turbine rotate to generate mechanical energy, and then drive the generator to rotate to convert the mechanical energy into electrical energy. Complete power generation. Compared with thermal power generation, hydropower generation has the advantages of not consuming limited coal resources and not directly producing pollution. my country is relatively rich in water energy resources, the total of which ranks first in the world. So far only 16% of water energy resources have been developed, and 74% of water energy ...

AI Technical Summary

Problems solved by technology

Fifth, water conservancy construction will inevitably destroy forest vegetation, and the spoil and concrete waste generated at the same time will seriously pollute the environment. In addition, the land occupied by the project and the land submerged by the reservoir are serious, which will have a great impact on the local natural ecosystem

Sixth, after the reservoir dam is filled with water, it will lead to substantial changes in the hydrogeology of the coastal area, and the state of groundwater will also change, which will bring about a series of geological problems, aggravate the destruction of vegetation, and cause disasters such as landslides and earthquakes

Seventh, each dam after completion has a service life of about 100 years, and must be forcibly dismantled when it expires, and the cost of dismantling is much higher than the cost of building a new dam
