Float open frame upper and lower position and adjust explanation: as shown in figures 7 and 9, toothed belt transmission Wave energy converting device exists
When normal power generation working condition, by the lifting regulating mechanism of buoyancy tank system, it is in the midpoint for floating open frame guide rod 404
The midpoint of peaks and troughs, such oscillating floater has along the up and down motion of guide rod 404 most runs significantly space；Here it is floatings
Open frame optimum position, generator operation state in the position are known as optimum Working.
The function of transfer principle and each part, component from wave energy to mechanical energy: wave energy is that wave motion is had
Some energy, it belongs to a kind of mechanical energy, and in irregular liquid surge motion state, the mechanical energy of this motion state is very
What hardly possible directly utilized；Mechanical energy after conversion mentioned here refers to that object moves possessed energy according to certain track,
Such as linear motion, rotary motion etc.；Such mechanical energy can be utilized directly, such as hydraulic rod piece is driven to move in a straight line
Or it makes rotating motion with moving axis；The essence of the conversion of mechanical energy described in the present apparatus is the transformation of the mechanical energy form of expression.
The function of each part of mechanical energy conversion device, component: referring to Fig. 5 and Fig. 6, under wave action, it is floating to inhale wave
Body 101 drives oscillating floater and drags synchronous belt 201 and move up and down along guide rod 404, and when oscillating floater uplink drives same
It walks 201 left side of band to rise, synchronous belt 201 is from the fixed device of synchronous belt down to synchronous belt reverse wheel 206, then arrives right load upwards
This section of synchronous pulley 204 is synchronous belt pilled-in selvedge；The fixed device of synchronous belt is upwards to left load synchronous pulley 202 and upper pinch roller
203 this section be synchronous belt slack list, at this moment, right load synchronous pulley 204 is rotated clockwise with right input shaft 211, the right side surmount from
Clutch 213 combines, and right input gear 212 is driven to rotate clockwise, and right input gear 212 is engaged with idle pulley 214, and idle pulley 214 is same
When engaged with output gear 215, driving output shaft 216 rotates clockwise and output power；Left load synchronous pulley 202 is suitable at this time
Hour hands are rotated and are dallied, and left freewheel clutch 210 is detached from.When oscillating floater downlink, synchronous belt 201 fixes device from synchronous belt
Down to commutation synchronous pulley 206, then arrive right load synchronous pulley 204 upwards, then to upper this section of pinch roller 203 be slack list,
Right load synchronous pulley 204 does rotation counterclockwise, at this point, right freewheel clutch 213 disengages；Synchronous belt 201 is fixed from synchronous belt
It is pilled-in selvedge that device, which passes upward through lower pinch roller 205 to left 202 this section of load synchronous pulley, and synchronous belt 201 drives left load same

Out under the driving of the unidirectional shaft joint 301 of axis connection, start to rotate, but its revolving speed is with the change of oscillating floater up and down motion speed
Change it is sometimes fast and sometimes slow, very unevenly, thus increase flywheel 302, drive axle speed rotation accelerate when, due to drive flywheel 302 rotate
And energy reserve, make that axle acceleration is driven to reduce, which shows as the rotary inertia of flywheel 302；When turning for drive shaft
When speed reduces even zero, since the rotary inertia that flywheel 302 stores makes flywheel 302 continue to rotate, transmission belt 303 into one is driven
Step drives the driving rotation rotary electric machine 305 of drive pulley 304 to continue to rotate, so that it is dynamic to reduce the input rotation of rotary generator 305
The fluctuation of power revolving speed is more advantageous to the balanced power generation of tuorbillion rotating motor 305 in this way；Note that the design of 302 rotary inertia size of flywheel is wanted
Properly, it to test when necessary.

Integral device has been held up, has prevented integral device from sinking again；The state is known as safeguard protection state, at this point, integral device is floating
The position of the heart is significantly larger than integral device center of gravity, causes a kind of highly stable configuration state in this way, as aerial manned
Basket-hanging balloon, as swum in the lifebuoy on the water surface, hung under it gravity less than buoyancy weight it is the same, center of gravity
It is very safe under centre of buoyancy；When bad weather terminates, by jacking system, integral device is made to readjust optimum position,
Continue to operate normally power generation.
Safe 403 design key point of floating body illustrates: safe floating body 403 is the guarantee of integral device existence, design key point,
The first, the gross buoyancy of safe floating body 403 should be equal to or more than the gravity of synchronous belt energy conversion device integral device；The second,
