Description of drawings
Do further explain below in conjunction with the accompanying drawing specific embodiments of the invention.
Fig. 1 is the structural representation (state when corresponding wave descends) of Wave power generation device of the present invention;
Fig. 2 is the schematic representation of Fig. 1 when wave rises.
Embodiment
Embodiment 1, Fig. 1 and Fig. 2 combine to have provided a kind of Wave power generation device, comprise shell 14, and this shell 14 is processed by reinforced concrete, thereby guarantee the sealing of whole casing 14.
In the inner chamber of shell 14, be provided with hydroelectric installation 1, vortex diode I7, vortex diode II11, low pressure jar 8, the pressure pan 13 of cable 9 and the liquid piston tube 3 that has liquid piston 4.Outer installment buoyancy aid 2 at shell 14.
Be respectively equipped with axial pipe I7a on the vortex diode I7 and cut out pipe I7t, be respectively equipped with axial pipe II11a on the vortex diode II11 and cut out pipe II11t.
Vortex diode I7 and vortex diode II11 are the control units that flows to of this Wave power generation device pipe-line system, and effect and one-way cock function class seemingly still do not have moving element.With vortex diode I7 is example, specifies as follows:
When liquid when axial pipe I7a gets into, cuts out pipe I7t and discharges, the overcurrent loss is very little, vortex diode I7 is on state; And when liquid was managed I7t entering, axial pipe I7a discharge from cutting out, liquid can form strong eddy current in vortex cavity, and the overcurrent loss is very big, and the interior liquid of vortex diode I7 is in the retardance state basically.
The axial pipe I7a of vortex diode I7 is connected with 8 sealings of low pressure jar, and the pipe II11t that cuts out of vortex diode II11 is connected with pressure pan 13 sealings; One end of connecting tube 5 is connected with the bore seal of liquid piston tube 3, the other end of connecting tube 5 respectively with the cutting out pipe I7t and be connected of vortex diode I7 with the axial pipe II11a of vortex diode II11 sealing.
Low pressure jar 8 is connected with hydroelectric installation 1 sealing through managing 6, and pressure pan 13 seals with hydroelectric installation 1 and to be connected through managing 10.
