The explanation converted from wave energy to mechanical energy：Wave energy is energy possessed by wave motion, it belongs to a kind of machine
Tool energy, is in irregular liquid surge motion state, and the mechanical energy of this motion state is difficult directly to utilize；It is referred to herein
Transformed mechanical energy refer to object according to energy possessed by certain track movement, such as linear motion, rotary motion
Etc., such mechanical energy can be utilized directly, such as driving hydraulic pressure rod piece is moved in a straight line or rotated with moving axis.From
The essence that wave energy is converted to mechanical energy is the transformation of the mechanical energy form of expression.
Explanation about one-stroke acting：This example drive mechanism is one-stroke acting, i.e., in a cycle of wave
Only the half period does work, and the idle running of half period is not done work；The structure lacks other than advantage noted earlier
Point is that the velocity perturbation of bigger can be caused relative to dual-stroke work application structure, can pass through different method solutions for this problem
Certainly, such as increase flywheel is taken, connected to the power plant of multiple spot, solved using the methods of hydraulic accumulation energy mechanism.
209 designing points explanation of flywheel：See Fig. 1 and Fig. 5, flywheel 209 include pass rotary generator 208 with speedup speed change
Device 207 exports under the driving of the unidirectional shaft joint 208 of axis connection, starts to rotate, but its rotating speed moves up and down with oscillating floater
The variation of speed is sometimes fast and sometimes slow, very uneven, increases flywheel 209 thus, winged due to drive when driving axle speed rotation to accelerate
Wheel 209 accelerates rotation, to make the reduction of driving axle acceleration, while energy being stored as to the rotary inertia of flywheel 209；Work as driving
When the rotating speed of axis reduces even zero, since the rotary inertia that flywheel 209 stores makes flywheel 209 continue to rotate, electric rotating is driven
Machine 208 continues to generate electricity, and to reduce the fluctuation of input 208 rotating speed of rotary generator, it is equal to be more advantageous to electric rotating machine 208 in this way
Weighing apparatus power generation；Notice that the design of 209 rotary inertia size of flywheel is suitable, to test when necessary.

Electricity, the safe floating body 303 positioned at truss upper mounting plate 302 are completely on the water surface；When encountering high sea or typhoon, lifting system
System exhaust, makes floating open frame decline, until dropping to when truss upper mounting plate 302 is in contact with oscillating floater, by oscillating floater
It is fixed with truss upper mounting plate 302.At this moment it inhales buoyancy possessed by wave floating body 101 and safe floating body 303 and can hold up entirety and set
It is standby, prevent integral device from sinking again；The state is known as safeguard protection state, at this point, the position of integral device centre of buoyancy is much
Higher than center of gravity, a kind of highly stable configuration state is caused in this way, such as aerial parachute, manned basket-hanging balloon one
Sample, center of gravity are very safe under centre of buoyancy；When bad weather terminates, by jacking system, integral device is made to come back to most preferably
Normal operation power generation is continued in position.
303 design key point of safe floating body：Safe floating body 303 be integral device existence guarantee, design key point, first
, safe floating body 303 gross buoyancy should be equal to or more than the gravity of integral device；The second, safe floating body 303 is designed to square position shape,
Band fillet, as shown in Figure 1 and Figure 7；Third, safe floating body 303 select good weatherability as possible under conditions of ensureing gross buoyancy, by force
Degree is high, the small floating body material of proportion；This example uses hollow box-structure.
This example apparatus integrality explanation：As needed, the state of equipment entirety can be carried out by jacking system
Adjustment；The first, as shown in figure 8, the up-down vibration midpoint of oscillating floater is identical as wave amplitude midpoint, in guide rod 304
Midpoint, work waterline shake above and below midpoint, and state definition is in working condition；The second, as shown in figure 9, when encountering high wind wave
When, it is stopped, jacking system exhaust, equipment entire lowering to deep waterline position, oscillating floater and safe floating body 303 are common
Support floats equipment entirety；When high wind wave is gone over, integral device can readjust original state, which is defined as safety
Guard mode；Third, as shown in Figure 10, when integral device needs mobile or when repairing, jacking system inflation makes in integral device
It is raised to towage waterline position or suitable maintenance position, which is defined as towing condition or service mode.
About the explanation for improving generated output approach：In the case of the identical wave height in sea level region of equal areas its
Wave energy is equal, and by increasing the area on sea level shared by oscillating floater, such as dilated diameter can more absorb wave
The energy of energy, can improve the generated output of Wave energy converting device；On the basis of this example basic structure form is constant, add
The size of big oscillating floater, the intensity for reinforcing stress parts, the single-row chain that this example provides is changed to double strand chain or multiple rows of chain,
The power of the equipment such as freewheel clutch, speedup speed changer, rotary generator is accordingly increased, is the important of raising generated output
, effective approach.
This instance section equipment uses standard device, simple and reliable, at low cost, launches and recycling is easy, to instinct
The sample experiment that amount conversion equipment carries out is seen, is worked well；But also need to do further real sea situation experiment to equipment, also need
Expand generated energy and improvement, form perfect, reliable wave-energy power generation equipment as early as possible, to meet society to wave energy power station
