Wherein: 1 hull; 2 connector elements; 3 pairs of rod oil cylinder energy conversion equipments; 4 arc track parts; 5 cross bars; 6 ramp structures; 7 connection sets.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Be a kind of wave energy generating set as Figure 1-4, comprise hull 1, on hull 1, be symmetrically arranged with multiple for wave energy being converted to two rod oil cylinder energy conversion equipments 3 of electric energy by connector element 2; Connector element comprises the arc track parts 4 that are fixedly connected with hull; The piston rod bottom of two rod oil cylinder energy conversion equipments is vertically installed with the cross bar 5 for slidably reciprocating on arc track parts; The both sides of hull upper surface are set to produce the excessive concentrated ramp structure 6 of stress for preventing from contacting with floating comprehensive energy platform lower shoe in the time there is maximum rolling; Hull longitudinal axis central position is provided with the connection set 7 for being connected with floating comprehensive energy platform; The underpart of the piston rod of connector element 2, two rod oil cylinder energy conversion equipments and hull surface are provided with coated water proof rubber material, are so more conducive to move in ocean.
Working principle:
Boats and ships depart under external force its equilibrium position and tilt, and after external force disappears, can be returned to voluntarily the ability of original equilibrium position, are called vessel stability.Vessel stability is the ability that boats and ships keep its original position after External Force Acting disappears in other words.
Boats and ships are static while floating on a certain position of the water surface, are subject to two active forces of gravity and buoyancy, its equal and opposite in direction, but opposite direction, and also both point of action are on same vertical line, and at this moment boats and ships are in state of equilibrium.But when boats and ships ride the sea, be often subject to the interference of the various external force such as stormy waves, make it produce, so just destroyed the state of equilibrium while originally top-uping.Boats and ships are being subject to can or can not overturning after External force interference produces and can or can not be returned to original equilibrium position when boats and ships after external force disappearance, the stability problem of Here it is boats and ships.
The cross section of ship, this ship small angle that tilts lentamente under external force (heeling moment) effect, waterline is when top-uping
wLbecome after inclination
w1
l1, the weight of ship does not change before and after tilting, and the center of gravity of ship remains on original position, therefore the size of the displacement of volume of ship does not also change.But due to the variation of waterline position, the shape of the draining of hull (under water) volume changes, therefore centre of buoyancy is from origin-location
bpoint moves on to
b1 point.Now, centre of buoyancy and center of gravity are no longer positioned on same vertical line, thereby buoyancy and a couple of gravity formation, impel ship to be returned to original equilibrium position.
From center of gravity
gmake straight line
gZperpendicular to passing through
b1 vertical line (being floating function line), the square of couple equals Δ
gZ, be called restoring torque, conventionally with
mr represents,
MR=Δ
GZ
In formula
gZfor righting arm.
If the opposite direction of restoring torque and heeling moment, it plays a part opposing heeling moment,
mr be on the occasion of.Now, once external force disappears, it can make boats and ships be returned to the equilibrium position of originally top-uping.If restoring torque is identical with the direction of heeling moment, this does not only play opposing inclination, impels on the contrary boats and ships to continue to tilt, now
mr is negative value.
As shown in Figure 3 and Figure 4, the present invention is the wave energy generating set of oscillating float type, adopt float type technology: utilize heeling moment and the restoring torque of the float of hull formula to produce to-and-fro motion, the hydraulic system of the intermediate mediums such as driving device system or oil, water, then promote electricity generating device generating.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
