Bottom-sitting tidal current generation turbine

Abstract

The invention provides a bottom-supported tidal-current generation water turbine. The bottom-supported tidal-current generation water turbine comprises a first impeller assembly, a first gear tumbler, a first speed increaser, a power generator, a second speed increaser, a second gear tumbler and a second impeller assembly, wherein the first impeller assembly, the first gear tumbler, the first speed increaser, the power generator, the second speed increaser, the second gear tumbler and the second impeller assembly are connected in sequence. A braking device is arranged between the first speed increaser and the power generator. The first gear tumbler, the first speed increaser, the braking device, the power generator, the second speed increaser and the second gear tumbler are arranged in a protective cover. The bottom-supported tidal-current generation water turbine has the beneficial effects that the gear tumblers are driven through the impeller assemblies, the rotating speeds, transmitted by the gear tumblers, of spindles of the impeller assemblies are increased through the speed increasers, and the rotating kinetic energy of the impeller assemblies is converted into electric energy by the power generator; by arranging the first impeller assembly and the second impeller assembly, both forward water flow and reversed water flow can push the power generator to generate power, and the power generation efficiency is improved; and by arranging the protective cover, typhoon attacks can be resisted, and the stability of the generation water turbine is improved.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a bottom-sitting type tidal current generating water turbine. Background technique [0002] Sustainable development and environmental protection have always been the common issues of global economic development. Due to the effectiveness of fossil energy and the threat to the human living environment, people have to strengthen the effective development and utilization of renewable resources, and the ocean tide is a clean Non-polluting and abundant reserves of renewable new energy, the use of tidal current energy to generate electricity has always been favored by various countries. [0003] In shallow seas, straits, bays or estuaries, high tides and low tides will cause strong currents and high water flow speeds. The kinetic energy of the tidal currents can be directly used to drive hydro turbines to generate electricity, which is called tidal current generators. Mo...
