Field.
Background technique
From wind-force, wind-force acts on seawater and gives the acceleration of wave bring by a thousand li ten thousand is inner wave energy, makes wave
With very big energy, but since wave energy has biggish pulsating nature, it can not be applied to electricity generation system, turned in energy
After the wave energy of capture is converted mechanical energy by changing device, usually also need to set between generator and wave energy conversion device
It sets energy output system and carrys out peak load shifting, thus the input power of stable generator, not only structure is complicated for this system, Er Qiezhuan
Change low efficiency.
Application No. is 201711042907.4 Chinese invention patents to provide a kind of fluid pressure type wave-power device, uses
Floating body collects floating up and down for wave, and converts energy into electric energy by the power switching device between floating body and generator,
Power switching device includes hydraulic cylinder, the first control valve, accumulator, fuel tank and hydraulic motor, and floating body floats up and down with hydrodynamic pressure
The piston rod of cylinder moves up and down；The piston rod of hydraulic cylinder, which moves up and down, is pumped to accumulation of energy by control valve for the hydraulic oil in fuel tank
Hydraulic oil driving hydraulic motor rotation in device, in accumulator；Hydraulic motor is connected by power generator and can driven generator hair
Electricity work acquires the energy of wave by using the hydraulic cylinder of lasting fuel feeding, and by accumulator and hydraulic motor to hair
Motor uni-directionally drives power generation.This electricity generation system carries out energy storage power generation by hydraulic system oil circuit, and energy is successively converted
For mechanical energy, hydraulic energy, mechanical energy and electric energy, centre experienced multiple energy conversion stages, greatly reduce generating efficiency；Together
When need to be arranged the power control units such as solenoid valve, once some component malfunction, which will result in total system, cannot achieve hair
Electricity, stability are poor；Floating body is placed in top in device, separates with generating equipment, takes up a large area, higher cost.
And generator used by wave-energy power generation is Double-directional rotary mostly in the prior art, passes through generator coil
Rotation, cutting magnetic induction line start power generation operation, however need when generator Double-directional rotary by one-directional rotation-one-directional rotation
The process of braking-opposite direction starting-opposite direction rotation, the huge inertia for needing to overcome in braking process, causes the damage of energy
The abrasion of consumption and generator components.
Summary of the invention
In order to overcome various deficiencies of the existing technology, the present invention provides a kind of wave energy generating set, energy utilization
Rate is high, and occupied area is smaller, and cost is relatively low, and generating efficiency is high.
To solve the above-mentioned problems, a kind of wave energy generating set of the present invention, including main structure, generating set and piston
Component, the main structure are hollow cylinder structure, and bottom circumferentially has outer, and the lower end of outer is uniformly fixed with several
Dagger, the fixed waters off shore of support column；Main structure upper end cavity is divided into upper hydraulic cylinder and lower hydraulic cylinder by intermediate bulkhead,
The piston component is made of upper end piston, connection piston and lower end water storage piston, and the surface area of upper piston is less than lower end water storage
The surface area of piston, upper end piston are arranged in lower hydraulic cylinder, and outer diameter hydraulic cylinder bore under matches and in upper end piston
It sets with lower hydraulic cylinder contact site to sealing ring, the fixed restraining position ring block in the bottom of lower hydraulic cylinder cavity is for limiting upper end piston
