Two-stage seawater power generation method

Abstract

The invention relates to a two-stage seawater generation method which is characterized by comprising the following steps: on a coastal available coastline, building a first drop platform (3) at a position which is 3-5m below the sea level, wherein the drop platform (3) is equipped with a water channel (1) for introducing seawater, and the outlet of the water channel (1) is equipped with a water gate (2); opening the water gate (2), and leading the seawater into drop to drive a first-stage hydraulic generator (4) to generate electricity under the action of potential energy; delivering the seawater into a water pump (6) through a seawater transmission water channel (5); utilizing the via the water pump (6) to pump the seawater which pushes the first-stage hydraulic generator (4) to generate electricity into a reservoir (8) through a suction pipe (7), wherein the reservoir (8) is arranged on a second drop platform (10); opening the water outlet valve (9) of the reservoir (8), and leading a second-stage hydraulic generator (11) to generate electricity by the seawater in the reservoir (8) under the action of potential energy formed by drop of the second drop platform (10); and finally transmitting electricity generated by the second-stage hydraulic generator (11) to users. The two-stage seawater generation method has the beneficial effects of greater transmitted electric quantity, small floor area, small investment, simplicity, feasibility, strong practicability, easy implementation.

Description

Technical field [0001] The invention relates to a method for seawater secondary power generation. Background technique [0002] At present, the whole world is advocating energy conservation and emission reduction. Premier Wen also promised the world in 2010 that my country will reduce emission reduction targets within 10-15 years. Because of the locality and pollution of dye-based non-renewable energy sources, international and domestic industries have turned to inexhaustible seawater, wind power and solar power generation; for seawater power generation, there are many mature and immature technologies. Seawater power generation is still in the experimental stage and cannot be widely promoted and applied. There are two reasons for this. One is that the technology is immature, and some of them are just assumptions. For example, various seawater power generation methods such as wave power generation, high tide power generation, and plasma power generation that are being tested...

Problems solved by technology

Because of the locality and pollution of dye-based non-renewable energy sources, international and domestic industries have turned to inexhaustible seawater, wind power and solar power generation; for seawater power generation, there are many mature and immature technologies. Seawater power generation is still in the experimental stage and cannot be widely promoted and applied.

There are two reasons for this. One is that the technology is immature, and some of them are just assumptions. For example, various seawater power generation methods such as wave power generation, high tide power generation, and plasma power generation that are being tested cannot be put into use and application; The second is that the technology is relatively mature, and the specific implementation and application are greatly restricted by objective conditions, such as high technical content, large investment, and cannot meet the needs of large enterprises and civilian electricity.

Judging from the current situation, the international and domestic seawater power generation methods are just an invention, and cannot be popularized and applied for a long time.
