The content of the invention
Object of the present invention is to provide it is a kind of can buffer soft cable stress while the buffering self power generation that is generated electricity
Formula wave propeller.
The design of the present invention：
One kind buffering self-power generation type wave propeller, including：Soft cable, power set buffer self-generating device.Soft cable is by steel
The flexible materials such as cord are constituted, and power set are made up of middle position-limit mechanism and swing type hydrofoil.Soft cable is by buffering certainly
Locking buckle on TRT connects together the power set below upper float and the water surface.
If not buffering self-generating device, the relative motion between power set and upper float in wave can be in soft cable
Very big pulling force is produced, damage is caused to soft cable connecting portion, and buffers the presence of self-generating device so that soft cable pulling force is obtained
Buffering, meanwhile, it is the charging of wave glider.
Self-generating device is buffered, includes magnetic piston, limit spring, mounting flange, kinematic link.
Buffer the bottom that self-generating device is arranged on upper float by mounting flange.
Far water face one end of institute's kinematic link is connected with magnetic piston, and approximately level one end is connected with soft cable, and magnetic is lived
The top of plug is consolidated with limit spring, and the other end of limit spring is fixed on the equipment top of buffering self-generating device.
When generation pulling force in relative displacement, soft cable is produced between power set when upper float and under water, soft cable tie
Dynamic kinematic link so that the magnetic piston of kinematic link one end overcomes the effect of the pulling force of limit spring, moves downward, passes through limit
The effect of position spring, the transient state pulling force being applied on soft cable is transferred on limit spring so that the pulling force of soft cable is obtained
Buffering, by the transmission of the power of mounting flange, is gradually applied on upper float, and by wave force with limit spring elastic potential energy
Form store.
When the pulling force that upper float is crossed on crest location, soft cable reduces, limit spring is stored in it before
In wave stretchy kinematic link, lifting the water surface below power set.Power set are downward along wave in wave glider
It is the wing plate using the weight-driven swing type hydrofoil of itself during operation, therefore lifting power set improve its operating efficiency.
Meanwhile, magnetic piston comes back to original position in the presence of the restoring force of limit spring, is soft cable next time by transient state
Pulling force is prepared.
In whole process, because magnetic piston is that tool is magnetic, and in the outer wall of buffering self-generating device, inlay
Multiplex induction coil, is transmitted connecting rod and limit spring in magnetic piston and pulls repeatedly, is constantly transported in buffering self-generating device
In dynamic process, magnetic piston constantly with the multiplex induction coil phase separation inlayed, be that there is provided additional for the charging of wave glider
Electric energy.
The beneficial effects of the present invention are：
The soft cable of power set is repeatedly subjected to transient state pulling force in motion process, long The present invention reduces wave propeller
Fatigue damage under phase operation and the wave stroke damage under high sea situation, increase the service life of wave glider, navigate by water energy
Power is improved.
Buffering self-generating device is fixed on upper float bottom, and larger do will not be produced to the motion of wave glider in itself
Disturb.
When upper float crosses crest, the buffering self-generating device discharges wave energy, and power set are lifted by soft cable,
The operating efficiency for the power set for improving by gravity sinking to convert energy.
Multiplex induction coil is inlayed in the outer wall for buffering self-generating device so that the magnetic piston in device is being transported up and down
The interaction with induction coil can be produced in dynamic process, is charged to wave glider, increases total delivery.
