Description
Technical field
The present invention relates to a kind of wave energy generating set hydraulic speed-changing system through optimal design.
Background technique
Undoubtedly, wind-force institute's role on energy production market has obtained everybody and has generally acknowledged.Though the domestic wave energy power generating equipment of at sea not installing on a large scale as yet is not far from the epoch of market marketable product.
The THE UTILIZATION OF WAVE ENERGY that various countries are studied includes it and once changes with secondary and change.Once conversion is grown form---the rotation function and the potential energy of fluid particles of utilization and converted wave.Up to now, occurred as conversion equipments of multiple wave energy such as the canard of nodding, pendulum-type, extra large freshwater mussel formula, oscillaton water column type and float types; The secondary conversion promptly becomes electric energy by carrying out secondary conversions such as turbine, hydraulic pressure after the once conversion of wave energy again with them.
At present the wave energy conversion equipment being incorporated into the problem that is faced in the power distribution network that has built up is, irregular power supply need be converted to the electric current of rule, wishes that simultaneously the size that can regulate electric current adapts to different demands.The front problem is overcome by the wave energy researcher, works out many methods simultaneously and solves this type of problem; The back problem still needs more researcher to make joint efforts.
Summary of the invention
The utility model relates to a kind of wave energy generating set hydraulic speed-changing system through optimal design.
The utility model mainly is made up of hydraulic speed-changing system, drive link, piston, throttle valve, series flow control valve, water turbine, generator, motion by drive link in the hydraulic speed-changing system comes flow of fluid in the control cylinder, total all needs waterproof seal, on the oil hydraulic cylinder major loop, increase the shunt of a connection, connection mouth is positioned in the middle of oil hydraulic cylinder two ends piston and the series flow control valve along separate routes, and lay a throttle valve along separate routes, play shunting action.Series flow control valve lays respectively at the water turbine both sides, the angle control fluid velocity magnitude of the switch by valve, and then regulate the water turbine rotational velocity.
Working principle of the present utility model is the ratio by near the front-end pipelines cross-section area regulator solution pressure and speed system's piston area and the water turbine, changes the movement velocity of water turbine inner fluid passage, thereby changes the rotating speed of water turbine.Such as, near the piston area of hydraulic speed-changing system and the water turbine front-end pipelines cross-section area ratio is 10, suppose that simultaneously wave energy is 2m/s in drive link place travelling speed, the speed of water turbine place fluid is exactly 20m/s so, thereby improve the rotating speed of water turbine, increased the generated energy of generator.If need to reduce the generated energy of generator on this basis, then can open and go up throttle valve along separate routes, with the shunting of oil hydraulic cylinder inner fluid, reduce the flow of liquid in the cylinder, thereby reduce the rotating speed of water turbine, and then reduce the generated energy of generator.

Embodiment
See also Fig. 2, this a kind of wave energy generating set hydraulic speed-changing system through optimal design comprises a shunting circuit, a throttle valve and two series flow control valves that are installed in the water turbine both sides.
This optimal design implementation process is the ratio by near the front-end pipelines cross-section area regulator solution pressure and speed system's piston area and the water turbine, and the shunting action of shunting circuit changes the movement velocity of water turbine front passage inner fluid, and then changes the rotating speed of water turbine.Such as, near the piston area of hydraulic speed-changing system and the water turbine front-end pipelines cross-section area ratio is 10, suppose that simultaneously it is 2m/s that wave energy makes the travelling speed of drive link, the speed of water turbine place fluid is exactly 20m/s so, thereby improve the rotating speed of water turbine, increased the generated energy of generator.If need to reduce the generated energy of generator on this basis, then can open and go up throttle valve along separate routes, with the shunting of oil hydraulic cylinder inner fluid, reduce the flow of liquid in the cylinder, thereby reduce the rotating speed of water turbine, and then reduce the generated energy of generator.
When needs increase the generated energy of generator, close throttle valve (7), change series flow control valve (8) valve switch size, reduce the cross-section area of pipeline inner fluid.Piston promotes the oil hydraulic cylinder inner fluid through series flow control valve (8), and flow velocity increases, thereby accelerates the rotating speed of water turbine, and then increases the generated energy of generator.
When needs reduce the generated energy of generator, change throttle valve (7) valve switch size, change series flow control valve (8) valve switch size simultaneously, pipeline inner fluid cross-section area is adjusted to maximum.Piston promotes the oil hydraulic cylinder inner fluid through throttle valve (7) and shunting circuit shunting, and another part fluid rotates through driving water turbine behind the series flow control valve, thereby reduces the rotating speed of water turbine, and then reduces the generated energy of generator.
Being used throttle valve (7) and series flow control valve (8) simultaneously can finely tune electric weight on the basis of improving the generated energy multiple.Use the ratio of series flow control valve (8) control generated energy, and then use the float value of throttle valve (7) fine setting generated energy.
