Embodiment
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Composition graphs 1 ~ 4, the present invention by raft body 3,10, hydraulic pressure installation 9, metal magnetic fluid generating device etc. form, hydraulic piston between each raft body 3,10 is divided into two groups, wherein one group gathers the energy of the rotation of raft body 3,10 substantially horizontal, and another group gathers the energy of the rotation between Vertical direction raft body 3,10.Wherein, all fluid cylinders 11,12,13,14 are unified to be fixed on a raft body 3, and all piston rods are hinged on another raft body 10 by respective articulated joint 15, thus realize the flexible operation of hydraulic pressure installation.It is spherical intermediate portion is in columniform seal container that liquid metal magnetohydrodynamic 2 is placed on two ends, can free-flow, the spherical container 8 outer side center point at these seal container two ends is fixedly connected with inelastic rope, the rope the other end is by the central point of the joint 1 connecting cylinder body raft body circular flat that is connected, thus this seal container is fixed on Fa Ti center.According to electromagnetic principle, in seal container cylindrical pipe both sides, magnet 5 is installed, liquid metal cutting magnetic induction line when flowing back and forth along with waving of raft body 3,10 can be made then to produce electric energy, and the pipeline relative with magnet 5 adopts thin pipe 6, the speed of liquid metal fluid 2 can be improved, thus produce stronger electromotive force, then by power conversion system 7, ocean wave energy is directly changed into the electric energy that user needs.
Each raft body and magnetohydrodynamic plant are relative to raft body Central Symmetry.
Two groups of fluid cylinders between raft body 3 and raft body 10 are symmetrical mutually, make raft body not by unnecessary external force.
Wave energy generating set of the present invention is made up of multiple raft body, liquid magnetofluid electricity generating device, hydraulic pressure installation.Each hydraulic pressure installation is made up of four fluid cylinders, is arranged in the side of each raft body, and symmetrical, symmetrical up and down.Liquid magnetofluid electricity generating device is made up of liquid metal, seal container, magnet and power range system.
1) when raft body 3 waves along with the fluctuating of wave, between each raft body, produce horizontal and vertical angular displacement, thus make fluid cylinder 11,12,13,14 that fore and aft motion occur, convert kinetic energy to electric energy.
2) each liquid magnetofluid electricity generating device (Fig. 3) is followed each raft body and is done identical waving, simultaneously, liquid magnetofluid metal 2 flows in seal container, cut the magnetic induction line sent by the magnet 5 be placed on around seal container, produce electric energy, and by power range system 7, electric energy output is used for user.
3) two power generation system independent operatings, do not disturb mutually.
Liquid magnetofluid metal 2 along with raft body 3 wave from do flow to the right time, the magnetic field produced by magnet 5, produces the electric current of forward, when fluid does opposite direction flowing, the both positive and negative polarity of change magnet, then still produce the electric current of forward, electric current is sent to the external world through power range system 7 again;
The pipeline relative with magnet adopts thin pipe 6, can improve the speed of the liquid metal fluid flowed from extra heavy pipe road 4, thus produces stronger electromotive force;
For the hydraulic pressure installation between raft body, in the horizontal direction, if fluid cylinder 11 compresses, then fluid cylinder 14 is expanded, same, in the vertical direction, if fluid cylinder 12 compresses, then fluid cylinder 13 is expanded, so, when producing constantly reciprocal angular displacement between raft body, the fluid cylinder between it is also constantly doing fore and aft motion, thus realizes generating.
Liquid magnetofluid electricity generating device is installed in the raft body of raft formula wave energy generating set inside by this device; absorbed more effectively by the energy of the angular displacement that wave makes raft body produce; and the seal container of magnetic fluid can be protected to exempt from seawater corrosion; the thick middle thin form in both sides taked by the pipeline of magnetic fluid; its speed can be improved in the free-pouring situation of guarantee magnetic fluid, thus improve generated energy and generating efficiency.It is simple that this device has structure, and working efficiency high, has vast potential for future development.
