Abstract
The invention provides a method for generating electricity by using seawater, which comprises a generator and seawater and is characterized in that a cylinder sleeve is fixed on the sea bottom, a floating body is arranged on a wave-facing surface of the sea surface and connected with a piston in the cylinder sleeve, the piston is compressed when being lifted, air in the cylinder sleeve is compressed when falling reversely, a valve of a non-compression cylinder sleeve is opened to inject air when the piston is reversed, the compressed air is introduced into a pressure container through a check valve, a cylinder or a steam-jet turbine structure is pushed by the compressed air to drive the generator to generate electricity, the electricity is generated by using wave energy, the energy is inexhaustible, the investment is less, the effect is quick, and the economic benefit is very high.
Description
Technical field
The present invention relates to a kind of method of utilizing water to generate electricity, especially a kind of method of utilizing seawater to generate electricity.
Background technique
Wave energy is meant kinetic energy and the potential energy that the ocean surface wave is had, the energy of wave and wave height square, cycle of motion of wave and the width of meeting the corrugated be directly proportional, wave energy is the least stable a kind of energy of energy in the marine energy, wave energy is given the ocean energy transfer by wind and is produced, it comes down to have absorbed wind energy and forms, rate of energy transfer is relevant with wind speed, and is also relevant with the distance (being the wind district) of water mutual effect with wind.
Summary of the invention
The present invention is directed to the defective of prior art, a kind of method of utilizing seawater to generate electricity is provided.
To achieve these goals, the present invention takes following measure to realize:
A kind of method of utilizing seawater to generate electricity, comprise generator, seawater, it is characterized in that in the seabed fixedly cylinder sleeve, one buoyancy aid is set connects piston in the cylinder sleeve, the air when piston is lifted gas in the compression cylinder sleeve on the corrugated of meeting on sea, reverse compression during the whereabouts, when reverse, open the valve injecting gas of non-compression cylinder sleeve, and pressurized air is imported in the pressurized container, generate electricity by pressurized air promotion cylinder or jetted turbine engine structure interlocking generator by safety check.
The present invention has following effect with respect to prior art: adopt wave energy to come environmental protection environmental protection, renewable, expensive few.
Embodiment
Wave force is converted to pressurized air drives the air turbine generator for electricity generation, when wave rises, the air in the air chamber is pushed up up, pressed air to pass that the positive pressure water valve chamber enters the malleation cylinder and the air turbine that drives on the generator shaft extension end makes generator for electricity generation, when wave falls, can promote acting by the gravity of buoyancy aid.
Wave can size can estimate i.e. P=0.5TH with the rise and fall variation of potential energy of seawater
2(P is the wave power on the unit wave front length, the kw/m of unit, T is a wave period, the s of unit, H is a wave height, the m of unit, in fact the size of wave power is also all multifactor relevant with wind speed, wind direction, the time of drying continuously, flow velocity etc.), therefore the energy level of wave energy is generally represented with kw/m, represent the speed of the line that energy grows by a 1m who is parallel to wavefront.
The wave energy of big midocean is difficult to extract, therefore can only be confined to the place in close shore line for the wave energy resource of utilizing, even but like this, wave energy resource reserves at the reasonable coastal area of condition probably also surpass 2TW, the whole world wave energy that can develop reaches 2.5TW according to estimates, and it is the wave train of 9s that the coastal significant wave height of China is about 2～3m, cycle, and wave power can reach 17～39kw/m, there is very high application prospect in Bohai Sea Gulf more up to 42kw/m.
In the reality, the present invention is used for power field, the wave energy money generating of utilization, and the energy is inexhaustible, little investment, instant effect has very high business efficiency.
