Problems solved by technology

These methods either do not solve the underlying problem, or are unacceptable due to increased cost and reduced availability
Adding an inertia wheel can only stabilize the energy output within a few seconds; charging the battery can achieve stable energy output, but the life of the battery is very short, and its inverter system is very expensive; networking with the grid often requires huge investment to build Some new energy installations become a kind of decoration, and the electricity price is very low in places with grids, so there is no demand for new energy

Embodiment Construction

[0015] The structure of the phase-change energy storage stable power generation device utilizing ocean wave energy will be further described in detail below in conjunction with the accompanying drawings: as shown in the accompanying drawings, the float 1 moves in the waves with the ups and downs of the waves, and the movement of the float 1 drives with it. The linked transmission link 2, the transmission link 2 presses the hydraulic pump group 3, and the hydraulic pump group 3 injects water into the interior of the sealed container 5 through the water inlet pipe 4; the interior of the sealed container 5 is filled with gaseous energy storage working medium R152a from top to bottom 6. It is composed of liquid energy storage working medium R152a 7 and seawater 8; at the other end of the sealed container 5, there is an outlet pipe 9 and a drain pipe 10. The function of the drain pipe 10 is to discharge when the input energy is too large and too fast and exceeds the safe receiving ra...

Abstract

The present invention relates to a new technology of utilizing unstable energy source in generating electricity and outputting stable energy. An outer drive force produced by unstable energy source produces power, transmission work medium is fed to sealed system with energy-accumulating stabilizing work medium, and the output of the sealed system is then used to drive power generator set to produce electricity. The present invention can be used in the field of utilizing and developing marine energy, wind energy and other unstable energy source to obtain stable output energy.

Description

technical field [0001] The invention belongs to a new method for generating electricity by utilizing unstable energy sources, and relates to a new technology for outputting stable energy. Background technique [0002] In the known unstable energy utilization methods, such as using ocean energy, wind energy, etc. to generate electricity, there is basically only an energy conversion device between energy input and output, and the biggest problem in this field is the instability of input energy. Due to its uniqueness, there are insurmountable congenital shortcomings in many aspects such as conversion efficiency, device safety, and device stability. Currently, the stabilizing technologies used include mechanical energy storage with inertia wheels, chemical energy storage for battery charging, or connecting the power generation device with the power grid or diesel engine for network operation, and using the large capacity of the power grid or diesel engine to fill the gap in the ...
