Multifunctional waterwheel for generating electricity by wake flow

Abstract

The invention discloses a multifunctional waterwheel for generating electricity by a wake flow. The multifunctional waterwheel comprises a flood control dam (1), a water turbine (2), a fluctuating type water way (3), an electricity generating waterwheel (4), a sightseeing culvert (5), an electricity generating waterwheel (6), a slow flow water wall (7), an electricity generating waterwheel (8) and a stable slow flow water surface (9). The working process of the multifunction waterwheel is as follows: the primary electricity generation is performed by a water flow through the water turbine (2); the kinetic energy of water cannot be totally absorbed; a big part of kinetic energy is leaked; and the water flow with high flow velocity flows to the downstream through the electricity generating waterwheel (4), the sightseeing culvert (5), the electricity generating waterwheel (6), the slow flow water wall (7) and the electricity generating waterwheel (8) to realize energy dissipation and flow stabilization of the water flow so as to prevent high impact of the water flow on a river channel or even the destroying of the river channel. The sightseeing culvert (5) provides a sightseeing spot to tourists for sightseeing the bottom of the river channel and observing the waterwheel at short range. The electricity generating waterwheels (4, 6, 8) provide the functions of energy dissipation and electricity generation, and realize the economic value of the waterwheel landscape.

Description

technical field [0001] The invention relates to a multifunctional waterwheel, in particular to a multifunctional waterwheel which utilizes wake flow to generate electricity. Background technique [0002] The construction of large-scale reservoirs has brought huge benefits in flood control and power generation. However, under the working condition of a large amount of water storage in reservoirs with good regulation performance, regular water temperature stratification occurs in the reservoir along the water depth. On the one hand, this phenomenon of water temperature stratification changes the living structure and behavior of aquatic animals and plants in the reservoir area, affecting the water quality in the reservoir area; The temperature of the tail water released in winter is higher than the natural situation, and the temperature of the tail water discharged in spring and summer is lower than the natural situation. The discharged low-temperature tail water has low tempe...

AI Technical Summary

Problems solved by technology

The discharged low-temperature tail water has low temperature and low dissolved oxygen content, which will have a greater impact on downstream fisheries and agriculture: it is extremely unfavorable to fish spawning, growth and predation, resulting in reduced fish production and even some fish The extinction of resources, and the release of low-temperature water will also cause "chilling damage" to crops, resulting in reduced production or even extinction
