Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the annexation top view of Fig. 1 middle pulley axle and output shaft.
Specific embodiment
As shown in Figure 1, 2, the guide frame 1 of the present invention is fixed on bank base or shallow sea pile foundation or Large marine raft
On, constitute the basis of whole device；Directive wheel group 2 is arranged in guide frame 1, constitutes the guide rail of float 4；The braking of float 4
Mechanism 3 is arranged on guide frame 1, and arrestment mechanism 3 can adopt frictional damping mechanism or mechanical interlock mechanism, by brake
Structure 3 can control locking and the release of float 4；Float 4 is arranged in directive wheel group 2, and float 4 can be made in directive wheel group 2
Move up and down；Float 4 be one in cylinder or ellipsoid, for ensureing that float 4 do not flood by wave at work, float 4 must
Must there is certain altitude, float 4 bottom is set to spindle or taper, in order to improve undershoot depth, float 4 top is provided with float even
Extension bar 5, float connecting rod 5 is passed through connection card 6 and is connected with a set of actuating device, and the upper end of float connecting rod 5 is passed through connection card 6 and connected
It is connected on the middle part of cable wire 11 in actuating device；This actuating device includes being fixed on the bracing frame 8 on guide frame 1 top, props up leading
Support each fixing a pair of bearing 12 about 8, pulley spindle 13 is arranged on bearing block 12, and assembly pulley 9 is fixing with pulley spindle 13 even
Connect, cable wire 11 is wound with assembly pulley 9, be provided with tensioning wheel 10 outside cable wire 11, tensioning wheel 10 is fixed on bracing frame 8, rise
To the tension to cable wire 11 so that will not skid between cable wire 11 and assembly pulley 9；Pulley spindle 13 passes through plus unloading clutch
14 are connected with power output shaft 15, plus unloading clutch 14 is typically general clutch, plays the effect of float 4 Load-unload, moves
Power output shaft 15 is connected with electromotor；In float 4 install adjust water pump 7, adjust water pump 7 on be connected with take out, drain pipe 16, lead to
Overregulate that water pump 7 is taken out, the ballast water of arranging in float 4 adjusts the weight of float 4, to guarantee float 4 weight with above degree of leaping high substantially
Coupling；Detection control apparatus is general detection control apparatus, and detection control apparatus includes computer and unrestrained high detection, wave speed inspection
Survey, control element, unrestrained height, wave type, unrestrained speed are measured, analysis draws optimal braking, unloading, loading, governing time, and leads to
Crossing control element controls whole system to run；Detection control apparatus passes through to control arrestment mechanism 3, adds unloading clutch 14, adjusts
Water pump 7 and generator excitation realize the locking of float 4, and -- -- upper punching -- loads the control of -- unloading -- undershoot-locking process for unblock
System.
The workflow of the present invention:
When 1. starting working arrestment mechanism 3 and plus unloading clutch 14 all discharge, float 4 free floating, when wave reach low
When point float 4 undershoot depth is l (l=0 when initial), float 4 is locked immovable by arrestment mechanism 3；
2. when wave rises again, float 4 is motionless, and float 4 does not rise with wave, peaks or nearly high point when wave rises h
When, float 4 and wave plane have a float buoyancy force potential energy difference to be equal to the depth of h+l；Now discharge arrestment mechanism 3, plus unloading
Clutch 14 is in open mode, and pulley spindle 13 is departed from output shaft 15, and float 4 is unloaded, and buoyancy makes on float 4 constantly accelerates
OK；
3. naturally the rise and fall face brief acceleration that is a little up to the standard of float 4 is zero, but speed v is maximum, so float 4 may proceed to the water surface
Upper motion, slow down up until speed v be zero, now float 4 is primered above s height, and s is upper degree of leaping high, due to air
Resistance is less, s ≈ h+l.At this moment plus unloading clutch 14 closes, pulley spindle 13 and output shaft 15 synchronous axial system, under wave starts
During fall, float 4 is followed wave and is together declined, and float 4 relies on self gravitation (now float unit area gravity=s) band running wire 6,
Order about pulley 9-- pulley spindle 13-- power output shaft 15 and drive electromotor acting.Now float 4 decrease speed can not be too fast, leads to
Toning motor excitation control load size of haircuting makes float 4 decrease speed and wave decrease speed substantially be consistent；
4., when wave drops to lowest order (nearly low level), float 4 Unit Weight is done work as float 4 during wave high point in Shang Chong
Specific gravity during height s and float 4 are with wave dropping distance h product, work(=s*h.Now due under float 4 and wave synchronization
Fall, so float 4 still exceeds water surface s(or close to distance s), opens at once plus unloading clutch 14 unloads, pulley spindle 13 with
Output shaft 15 departs from float 4 zero load, pours water because the gravitational potential energy of action of gravity float 4 is converted into kinetic energy after float 4 zero load
L depth below face, l=ms, m are undershoot coefficient, and because water resistance is larger, m is relevant with undershoot depth and float 4 diameter, instantly
Rushing speed is braking locking when zero, and 2. system is returned to state, enters subsequent cycle.
Due to undershoot depth l deeper produce point on degree of leaping high s ≈ h+l higher, and on the higher next one of degree of leaping high s
Undershoot depth l is also lower, forms a positive feedback, because the deeper resistance of undershoot is larger, so reaching float 4 after a certain depth
Undershoot depth is basicly stable.The more low upper punching point of undershoot point is higher, due to float 4 unit area work done=s*h, the bigger s of l
Bigger, whole system work is bigger, so improving undershoot depth l as far as possible in the hope of obtaining bigger sea wave energy.The present invention
Operation scheme it may also is that 1, discharge time can be postponed to obtain more energy and to reduce undershoot when unrestrained high h is larger
Drag losses；2nd, when upper degree of leaping high s may exceed design height, section part can be jumped on float 4 and load fetching portion energy
And limit degree of leaping high s.Flexibly control arrestment mechanism 3 with the locking adding unloading clutch 14 and release to obtain ceiling capacity.
