The generating of marine tidal-current energy of the present invention and wave energy coupling and some work flow process and the working principle of freshwater production system are as follows.
When having wave to produce, float 104 can float on the water surface 800, float 104 floating band movable pendulum bars 103 swing up and down, thereby drive the swing arm that swings swing cylinder 1 in the device 102 that can be converted into hydraulic energy to swing, the energy that flows into the fluid of swing cylinder 1 from fuel tank 700 is increased, thereby swing can be changed into hydraulic energy, and be transported in hydraulic energy storage system 300.Fluid has two-way to flow in swinging the device 102 that can be converted into hydraulic energy, one tunnel is from A-B-C-D, another road is A-C-B-D, and wherein A is for swinging the fluid input end of the device 102 that can be converted into hydraulic energy, and D is for swinging the fluid output terminal of the device 102 that can be converted into hydraulic energy.The hydraulic pressure oil film chamber of floating drum 101 top and bottoms, the mainly effect of its locked floating drum 101, when wave produces, floating drum 101 also can slide up and down along pilum 600, the device output hydraulic pressure oil that now wave energy is converted into hydraulic energy enters in hydraulic pressure oil film cavity, in hydraulic pressure oil film chamber, form the pressure to pilum 600, this pressure produces frictional force between pilum 600 and hydraulic pressure oil film, and this frictional force can be locked on pilum by the floating drum in wave 101, avoids floating drum 101 to fluctuate.This process can automatically perform, and can certainly control throttle valve 117 by remote controllers and come regulator solution force feed to flow into the flow of hydraulic oil cavity, thus regulator solution force feed film, the frictional force to pilum 600, the whole device of balance.When having billow, the first switch valve 111 that remote controllers 403 are controlled on floating drum 101 intermediate portion cylinders is opened, the gas of 105 li of the first cavitys is discharged, note into seawater, the gravity that floating drum 101 and whole wave energy acquisition device 100 are sunk to floating drum after the 801(water filling of seabed is much larger than the buoyancy of floating drum and the frictional force between hydraulic pressure oil film and pilum, so floating drum can sink to seabed smoothly), prevent that wave energy acquisition device 100 is destroyed in billow.After billow, remote controllers 403 control gas flip flop equipments discharge gas and are full of air bag 112, the wave energy acquisition device 100 that sinks to seabed 801 is emerged to 800, now the first switch valve 111 is also in opening situation, valve port is discharged the seawater in floating drum 101 first cavitys 105, guarantee that wave energy acquisition device 100 is without prejudice in billow, continue operation.If what air bag 112 was in-built is chemicals, primary first-order equation need to be from the product of newly changing dressings after finishing.
When having trend, trend drives 200 Leaf 202 rotations of marine tidal-current energy acquisition equipment, blade 202 pump works in the rotary actuation fuselage 201 of blade 202, the energy that flows into the fluid of blade 202 pumps from fuel tank 700 is increased, thereby the energy of blade 202 rotations is changed into hydraulic energy, and be transported in hydraulic energy storage system 300.Empennage 205 after fuselage 201 can play the effect to water, if the direction of trend changes, the direction of whole marine tidal-current energy acquisition equipment 200 also can be around floating drum 101 rotations, until arrive the optimum efficiency to water under the effect of empennage 205.
The energy that the energy of wave energy collection and marine tidal-current energy are caught is all transported in hydraulic energy storage system 300 with the form of hydraulic energy, and wherein a part is stored in accumulator 309, and another part is directly required for generating and preparing fresh water.If electricity consumption or fresh water are in short supply certainly, the hydraulic energy in accumulator 309 also can be simultaneously for generating and preparing fresh water.Electricity generating device 400 drives power hydraulic motor 404 to rotate by hydraulic oil, and power hydraulic motor 404 drives generator generating.Preparing fresh water device 500 drives preparing fresh water oil hydraulic motor 503 to rotate by hydraulic oil, and preparing fresh water oil hydraulic motor 503 drives preparing fresh water high-pressure undersea water pump 504 that low-energy seawater is changed into high-octane seawater, then seawater is passed into preparing fresh water in reverse osmosis membrane group 505.
Generated energy and preparing fresh water amount can regulate automatically, such as to evening power consumption reduce, proportional flow control valve will regulate automatically, and the hydraulic energy that flows into electricity generating device 400 is reduced, the hydraulic energy that flows into preparing fresh water device 500 increases.To power consumption increase on daytime, proportional flow control valve will regulate automatically, the hydraulic energy that flows into electricity generating device 400 is increased, the hydraulic energy that flows into preparing fresh water device 500 reduces, the 5th pressure transducer 502 on 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 reduce preparing fresh water amount, otherwise contrary.Wave energy and marine tidal-current energy are all very unsettled, and when energy changes, the pressure transducer on device can both detect, and comprise the 5th pressure transducer 502 on preparing fresh water device 500.When energy increases, it is many that the switch valve 506 in reverse osmosis membrane group 505 is opened, and preparing fresh water is also many; When energy reduces, what the switch valve 506 in reverse osmosis membrane group 505 was opened lacks, and preparing fresh water is also few.Proportional flow control valve on it and switch valve 506 are all controlled by PLC, can certainly control with other controller.
