A tidal energy generating device

Abstract

The invention provides a novel tidal energy power generation device. The novel tidal energy power generation device comprises a hollow dam body, wherein at least one set of power generation assembliesare arranged in the dam body, the power generation assembly comprises a power shaft with one end connected with a generator, at least one set of water turbine assemblies is fixedly arranged on the power shaft, the water turbine assemblies comprise at least two concentric water turbine single bodies with different diameters horizontally arranged in series, front water inlet channels, a front wateroutlet channel and a front water inlet gate and a front water outlet gate are arranged in the front side wall of the dam body, a rear water inlet channel and a rear water inlet gate are correspondingly arranged on the rear side wall of the dam body, the water turbine single bodies correspond to the respective front water inlet channels and the rear water inlet channel, the position of the front water outlet channel and the position of the rear water outlet channel correspond to the water turbine single body with the smallest diameter, when in rising tide, the front water inlet gate and the rear water inlet gate are sequentially opened from a low position to a high position so that tidewater sequentially passes the water turbine single bodies with the diameters ranging from small to largethrough the corresponding front water inlet channels, then the water turbine assemblies are pushed to rotate.

Description

technical field [0001] The invention belongs to the field of tidal energy power generation, and in particular relates to a tidal energy power generation device. Background technique [0002] As traditional energy sources such as fossil energy and petroleum energy decrease and become exhausted, people will pay more and more attention to the development and utilization of water energy, wind energy, solar energy, tidal energy and nuclear energy. It will be a trend and a country's economic strategy. Water energy is limited by the terrain, and it is not that high mountains and valleys cannot build dams, and the construction cost is very high; solar energy requires the laying of solar panels on a large area, competing with the people for land. Wind energy is more restricted and needs to be built in a special tuyere area; the use of nuclear energy requires the construction of nuclear power plants, which is costly and has a risk of leakage. Once leaked, it will have a huge impact on...

AI Technical Summary

Problems solved by technology

In addition, the dam site selection, turbine design, and motor unit design of the existing tidal power stations are relatively backward, and the kinetic energy and potential energy of the tidal water cannot be fully utilized, which seriously affects the development and utilization of tidal energy. Now tidal energy generators in my country field is almost blank
