Abstract
The present invention relates to a power generator, namely a weighted floater sea wave power generator taking sea wave as power source which includes a floating weighted rigid base with a plurality of fluid pressure cylinder vertically hinged on it. cylinder rod outer end of Each fluid pressure cylinder connects with a floater, one-way high-pressure outlet mouth connect of each fluid pressure cylinder with inlet mouth of hydraulic slave motor, one-way low pressure pipetting mouth of each fluid pressure cylinder connects with outlet mouth of hydraulic slave motor, hydraulic slave motor connects with generator. Seesaw motion of seawave prompts floater floating on the sea and the floater drive cylinder rod reciprocate. One-way pipetting of the fluid pressure cylinder and one-way liquid pressing drive the hydraulic slave motor make the generator generating power. Electricity is transformed to ashore transforming plant through seabed multipurpose armoured cable, and then incorporated to electric network. Seawave kenetic energy is converted to electric energy in the invention which has features like simple structure, low operating cost and no pollution discharge.
Description
Technical field
The present invention relates to a kind of electricity generating device, can be the Weighted floater sea wave power generator of power source with the sea wave promptly.
Background technique
In prior art, thermal power generation, hydroelectric power, the extensive use of nuclear power station technology, wind-power electricity generation is popularized.There is power consumption in various degree in existing generation technology, is subjected to the high deficiency of natural condition restriction, immigrant, befouling environment or operating cost.Along with improving constantly of human living standard, people are also growing with each passing day to the consumption of the natural resources and the energy, and it is serious further that global environmental situation also just becomes.In consumption of fossil fuels, the harmful gas of discharging from the thermal power plant constitutes baneful influence to atmosphere environment, and people are in the appearance of looking forward to clean energy resource forwardly.
Summary of the invention
The objective of the invention is provides a kind of Weighted floater sea wave power generator that utilizes wave to generate electricity at above-mentioned deficiency.
Technical solution of the present invention is: Weighted floater sea wave power generator comprises the floating rigid base that heavily hangs down, vertical hinged a plurality of oil hydraulic cylinders that are placed with on the heavily vertical rigid base, the piston rod outer end of each oil hydraulic cylinder is connected with float, the one-way high-pressure liquid outlet of each oil hydraulic cylinder is connected with the liquid entering hole of oil hydraulic motor, the one-way low pressure liquid sucting port of each oil hydraulic cylinder is connected with the liquid outlet of oil hydraulic motor, and oil hydraulic motor is connected with generator.Make float float over the sea by the counterweight on the rigid base that heavily hangs down, the rigid base that heavily hangs down is suspended in the ocean, and the rigid base that heavily hangs down is provided with the location anchor cable that is connected with the seabed.
Electricity generating principle: wind and sea effect produce wave.Wave can be with one of hydraulic power potentials of kinetic energy form performance.Weighted floater sea wave power generator is established and is floated on the sea, moving up and down of wave promotes to swim in deepwater float, float drives piston rod and moves up and down, unidirectional imbibition and unidirectional hydraulic fluid by oil hydraulic cylinder drive oil hydraulic motor, drive generator for electricity generation, electric energy is transported to electric substation on the bank by seabed multipurpose belted type cable, and then is connected to the grid.Realization is converted into electric energy with the kinetic energy of wave.
Advantage of the present invention is: 1, simple in structure, operating cost is low.2, be not subjected to natural environment influence, influence ecological environment does not need the immigrant.3, consumes energy not, non-pollution discharge.
Below in conjunction with embodiment embodiments of the present invention are described in further detail.
