Low-resistance generator for river power generation

Abstract

The invention discloses a low-resistance generator for river power generation, comprising a magnetic tent, a core coil, and water blades. The magnetic tent is composed of two permanent magnet sets, all the N poles of one permanent magnet set face the interior of the magnetic tent, all the S poles of the other permanent magnet set face the interior of the magnetic tent, and thus, a radial magnetic field is formed in the magnetic tent. A stator is composed of a core and a coil. The stator is arranged in the magnetic tent through a rotating shaft which is at the gap of the two permanent magnet sets. The magnetic tent serves as a rotor, and the water blades are arranged in the magnetic tent. The water blades are of a slice structure, and bear water flow in the radial direction. The low-resistance generator for river power generation is technologically characterized in that the core composed of silicon steel sheets is a rod-like core of a certain length, and the coil winds the middle section of the rod-like core. The generator is of low resistance and high efficiency. Excess consumption of fire resources can be reduced by making full use of numerous horizontal-flow river resources throughout the country. Thus, the atmospheric environment, the ecological environment, the development environment and the human living environment are improved.

Description

technical field [0001] The invention relates to a generator, in particular to a light-resistance generator for river power generation. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the available wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are huge and widely distributed, with about 253 million kilowatts of wind energy reserves on land alone.

Problems solved by technology

[0005] However, wind power also encounters many problems in the development: 1. Noise and visual pollution; 2. Occupying a large area of ​​land; 3. Unstable and uncontrollable; 4. The current cost is still high; migration)

However, at present, the thermal efficiency of the power plant (coal-fired, oil-fired) that drives the generator cannot break through 54% (this can be described as an "eternal" technical bottleneck)

Constrained by the cost of superconducting use and the bottleneck of "eternal" technology, the actual situation faced by the market is that the output efficiency of generators is basically still around 75%, and water and fire resources continue to be excessively depleted
