Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] In the example, such as figure 1 , figure 2 , image 3 As shown, the tidal energy power generation device includes a dam body 1. The inside of the dam body 1 is hollow, and the inside of the dam body is filled with seawater during operation. Water inlet pipes 2 and gates 3 are provided on both sides of the dam body 1. The water inlet of the water inlet pipeline 2 is located below the sea level, and the inside of the dam body 1 is provided with an outlet pipeline 4 connected to the water inlet pipeline 2, and a generator set 5 is arranged in the water outlet pipeline 4, and the water inlet pipeline 2 An opening and closing device 6 is provided. When the tide level of the outer sea is higher than the tide level of the inner sea, the gate 3 on the inner sea side is opened, the water inlet pipe 2 is closed, and the water inlet pipe 2 on the outer sea s...

Abstract

The invention discloses a tidal power generation device. The problem that the high tidal fall is required by tidal energy power generation is solved. The tidal power generation device comprises a dambody; the interior of the dam body is hollow, and the two sides of the dam body are provided with a water feeding pipeline and a gate; a water inlet of the water feeding pipeline is located below thesea level, and the dam body is internally provided with a water discharging pipeline connected with the water feeding pipeline; and a power generation unit is arranged in the water discharging pipeline, and an opening and closing device is arranged on the water feeding pipeline. Through the characteristic that the velocity ratio is achieved through the fluid cross-sectional area ratio in the siphon principle and the Bernoulli principle, the purpose that a fluid moves in the pipelines at a high speed to push an impeller of the power generation unit to rotate to achieve power generation is achieved, a large amount of tidal energy which cannot be utilized currently is developed and utilized, and conditions are created for large-scale application of ocean energy.

Description

technical field [0001] The invention relates to the technical field of renewable energy, in particular to a tidal energy power generation device. Background technique [0002] Energy is the lifeblood of a country. Conventional fossil energy has promoted the development of human civilization as a basic energy source, but at the same time it will cause great damage to the natural environment; global common problems such as greenhouse effect, environmental degradation, and energy shortage are already very serious; tidal energy has distribution Wide, predictable, rich reserves, and renewable, non-polluting features have attracted unprecedented attention from all countries in the world. [0003] At present, when using tidal energy to generate electricity, most of them require a tidal difference of 5 or 6 meters, resulting in that the tidal energy lower than the tidal difference of 5 or 6 meters cannot be used and is wasted. Contents of the invention [0004] In order to overco...
