When wave produces; Float 104 can be in the water surface 800 float; Float 104 floats and drives forks 103 and swing up and down, thus drive swing can be converted into hydraulic pressure can device 102 in the swing arm swing of swing cylinder 1, the energy that flows into the fluid of swing cylinders 1 from fuel tank 700 is increased; Can change into the hydraulic pressure ability thereby will swing, and be transported in the hydraulic pressure ability storage system 300.Fluid has two-way to flow in swinging the device 102 that can be converted into the hydraulic pressure ability; One the tunnel is from A-B-C-D; Another road is A-C-B-D, and wherein A is the fluid input end that swing can be converted into the device 102 of hydraulic pressure ability, and D can be converted into the fluid output terminal of the device 102 of hydraulic pressure ability for swing.The hydraulic pressure oil film chamber of floating drum 101 top and bottoms, the mainly effect of its locked floating drum 101; When wave produced, floating drum 101 also can slide up and down along pilum 600, and this moment, wave energy was converted in the device output hydraulic oil entering hydraulic pressure oil film cavity of hydraulic pressure ability; In hydraulic pressure oil film chamber, form pressure to pilum 600; This pressure produces frictional force between pilum 600 and hydraulic pressure oil film, this frictional force can be locked on pilum with the floating drum in the wave 101, avoids floating drum 101 to fluctuate.This process can automatically perform, and can certainly control throttle valve 117 through remote controllers and regulate the flow that hydraulic oil flows into the hydraulic oil cavity, thereby regulate the hydraulic pressure oil film, to the frictional force of pilum 600, the whole device of balance.In the time of billow; First switch valve 111 on the remote controllers 403 control floating drums 101 intermediate portion cylinders is opened; The gas of 105 li of first cavitys is discharged, annotate seawater, floating drum 101 and whole wave energy collecting device 100 are sunk to seabed 801, and (gravity of floating drum is much larger than the buoyancy of floating drum and the frictional force between hydraulic pressure oil film and the pilum after the water filling; So floating drum can sink to the seabed smoothly), prevent that wave energy collecting device 100 is destroyed in billow.After the billow; Remote controllers 403 control gaseous flip flop equipments discharge gas and are full of air bag 112; The wave energy collecting device 100 that sinks to seabed 801 is emerged 800, and this moment, first switch valve 111 also was in the situation of opening, and valve port is discharged the seawater in floating drum 101 first cavitys 105; Guarantee that wave energy collecting device 100 is without prejudice, and continues operation in billow.If dress is chemicals in the air bag 112, then primary first-order equation need be from the article of newly changing dressings after finishing.
When trend; Trend drives blade 202 rotations in the trend ability acquisition equipment 200; Blade 202 pump works in the rotary driving machine body 201 of blade 202; Make the energy increase that flows into the fluid of blade 202 pumps from fuel tank 700, thereby the energy of blade 202 rotations is changed into the hydraulic pressure ability, and be transported in the hydraulic pressure ability storage system 300.Empennage 205 behind the fuselage 201 can play the effect to water, if the direction of trend changes, the direction of whole trend ability acquisition equipment 200 also can be around floating drum 101 rotations, till the optimum efficiency that arrives water under the effect of empennage 205.
The energy that the energy of wave energy collection and trend can be caught all with hydraulic pressure can form be transported to hydraulic pressure can storage system 300 in, wherein a part is stored in the accumulator 309, another part directly supplies generating and preparing fresh water required.If electricity consumption or fresh water are in short supply certainly, the hydraulic pressure in the accumulator 309 can also can supply generating and preparing fresh water simultaneously.Electricity generating device 400 drives power hydraulic motor 404 through hydraulic oil and rotates, and power hydraulic motor 404 drives generator for electricity generation.Preparing fresh water device 500 drives preparing fresh water oil hydraulic motor 503 through hydraulic oil and rotates, and preparing fresh water oil hydraulic motor 503 drives preparing fresh water high pressure sea water pump 504 low-energy seawater is changed into high-octane seawater, again seawater is passed into preparing fresh water in the reverse osmosis membrane group 505.
Generated energy and preparing fresh water amount are can be self-regulating, such as to evening power consumption reduce, proportional flow control valve will be regulated automatically, and the hydraulic pressure that flows into electricity generating device 400 can be reduced, the hydraulic pressure of inflow preparing fresh water device 500 can increase.To power consumption increase on daytime, proportional flow control valve will be regulated automatically, and the hydraulic pressure that flows into electricity generating device 400 can be increased; The hydraulic pressure that flows into preparing fresh water device 500 can reduce; The 5th pressure transducer 502 on the preparing fresh water device 500 detects the decline of branch road upward pressure simultaneously, will pass the signal along on the switch valve 506 of reverse osmosis membrane group 505, and part switch valve 506 cuts out automatically; Thereby it is reduce the preparing fresh water amount, otherwise then opposite.Wave energy and trend can all be very unsettled, and when energy changed, the pressure transducer on the device can both detect, and comprise the 5th pressure transducer 502 on the preparing fresh water device 500.When energy increased, it is many that the switch valve 506 on the reverse osmosis membrane group 505 is opened, and preparing fresh water is also many; When energy reduced, what the switch valve 506 on the reverse osmosis membrane group 505 was opened lacked, and preparing fresh water is also few.Proportional flow control valve on it and switch valve 506 all by PLC control, can certainly be controlled with other controller.
