P1248/NLpd
HYDRODYNAMIC SYSTEM BASED ON PRINCETON OCEAN MODEL
TECHNICAL FIELD
The present invention relates to the field of ocean dynamics and new energy, in particular to a ocean hydrodynamic system based on the Princeton ocean model.
BACKGROUND ART
Three kinds of common buoys are used for the oscillating buoy wave energy recovery device, including a cylindrical buoy, a buoy with a cylindrical upper portion and a conical lower portion, and a buoy with a cylindrical upper portion and a hemispherical lower portion. As shown in relevant research, the cylindrical buoy can provide the highest recovery efficiency under the same conditions, so the cylindrical buoy has the widest application range. However, despite of various shapes of the buoy, as shown in FIG. 10, the buoy is subjected to horizontal force due to kinetic energy of waves when its force point A oscillates, which will cause the buoy to vibrate, likely give rise to damage of transmission parts in the long run and shorten the service life of the device. In addi- tion, the buoy has a very complicated oscillating process, and will accelerate upwards once under the action of wave energy in a vertical direction, the buoy will push a guide rod to move up- wards, which makes joints bear great impact and is prone to damage the joints. Therefore, a hydrodynamic control system based on the
Princeton ocean model is proposed.
SUMMARY
A main objective of the present invention is to provide a hy- drodynamic system based on the Princeton Ocean Model. By mounting, inside an existing buoy body, a damping ball and a damping spring for absorbing impact kinetic energy, and arranging a diverter on an outer side the buoy body for consuming part of the kinetic en- ergy during impact, the problem that the buoy body is prone to damage due to vibration caused by impact may be effectively solved.
In order to achieve the above objective, the present inven- tion uses the following technical solution:
The hydrodynamic system based on the Princeton Ocean Model includes an oscillating buoy for wave energy absorption, a bidi- rectional rack bar for driving a transmission mechanism, the transmission mechanism for transferring kinetic energy, a cou- pling, a generator for generating electric energy and a mounting platform for mounting an apparatus, where the oscillating buoy in- cludes a cylindrical buoy body and diverters which are used for buffering and distributed around an outer side of the cylindrical buoy body, a damping spring for absorbing impact force is mounted inside the cylindrical buoy body, a damping ball is mounted at the other end of the damping spring, the damping ball is located at a center of the cylindrical buoy body, and a middle of an upper end of the cylindrical buoy body is rotatably connected to the bidi- rectional rack bar through a bearing.
Further, a middle and an end of the diverter are arranged in a fin shape. When waves impact on the cylindrical buoy body at a certain angle, a force-bearing surface of the cylindrical buoy body may bear component force in a horizontal direction. When the force acts on the middle of the diverter, the force may be divided into force in a parallel direction and force in a vertical direc- tion since the middle of the diverter is in a fin shape, and the force in the parallel direction may be mutually offset, the force in a vertical force-bearing surface varies, under the action of the force difference, the cylindrical buoy body rotates, such that part of the kinetic energy borne in the horizontal direction may be eliminated, and vibration of the cylindrical buoy body may be reduced. The end of the diverter is arranged cambered from an end away from the cylindrical buoy body to an end near the cylindrical buoy body, and an end surface, in contact with the cylindrical buoy body, of the diverter is also cambered, so the cylindrical buoy body reciprocates in the vertical direction under the action of the waves and its own gravity, a vertical component of wave en- ergy may act in an effective contact area between the cylindrical buoy body and the waves. The fin-shaped ends are arranged at an upper end and a lower end of the diverter, when the cylindrical buoy body moves, the waves are diverted along fin-shaped edges of the ends, reducing the effective contact area between the diverter and the waves and not affecting movement of a cylindrical body of the cylindrical buoy body.
Further, six diverters are arranged, and a distance between an outermost end surface of the diverter and a center line of the cylindrical buoy body gradually decreases in a clockwise direc- tion, so adjacent diverters vary in size, and when the waves im- pact on the cylindrical buoy body, and force acting on the adja- cent diverters vary, thus causing the cylindrical buoy body to ro- tate.
Further, the damping spring is mounted inside the cylindrical buoy body, four damping springs are arranged, and the damping springs are distributed around an outer side of the damping ball, so when the cylindrical buoy body accelerates upwards under impact of the waves, the damping ball still remains in a static state at an initial stage of movement, relative displacement is generated between the cylindrical buoy body and the damping ball, thus stretching the damping spring, converting kinetic energy into elastic potential energy of the damping spring, partially consum- ing the kinetic energy, and reducing the impact. The cylindrical buoy body has the same movement process when returning back, and the springs distributed in a circumferential direction may also absorb the kinetic energy in the horizontal direction, making the cylindrical buoy body move more smoothly, improving the reliabil- ity of a device and prolonging the service life of the device.
Further, the transmission mechanism includes an outer cylin- der and a driving gear, where an inner side of an end of the outer cylinder is connected to the bidirectional rack bar through a lin- ear bearing, a middle inside the outer cylinder is symmetrically provided with driving gears engaged with the bidirectional rack bar, the driving gear is internally provided with an overrunning clutch, an output shaft is mounted inside the overrunning clutch, an outer side of the output shaft is rotatably connected to the outer cylinder through a bearing, the other end of the output shaft is provided with a driven gear, an inner side of the driven gear is meshed with a generator gear, an interior of the generator gear is connected to an input end of the coupling, the output end of the coupling is connected to a main shaft of the generator, and buffer springs are symmetrically arranged inside the outer cylin- der.
Further, the transmission mechanism and the generator are fixed on the mounting platform, and a lower end of the mounting platform is fixedly connected to a platform support, and a bottom end of the platform support is fixed at seabed.
The present invention has the following beneficial effects:
Compared with the prior art, the damping spring and the damp- ing ball are arranged, so when the cylindrical buoy body acceler- ates upwards under impact of the waves, the damping ball still re- mains in a static state at an initial stage of movement, relative displacement is generated between the cylindrical buoy body and the damping ball, thus stretching the damping spring, converting kinetic energy into elastic potential energy of the damping spring, partially consuming the kinetic energy, and reducing the impact. The cylindrical buoy body has the same movement process when returning back, and the springs distributed in a circumferen- tial direction may also absorb the kinetic energy in the horizon- tal direction, making the cylindrical buoy body move more smooth- ly, improving the reliability of the device and prolonging the service life of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Embodiment 1
As shown in FIGs. 1-9, a hydrodynamic control system based on the Princeton Ocean Model includes an oscillating buoy 1, a bidi- rectional rack bar 2, a transmission mechanism 3, a coupling 4, a generator 5 and a mounting platform 6, the oscillating buoy 1 in- cluding a cylindrical buoy body 101 and diverters 102 distributed around an outer side of the cylindrical buoy body 101, where a damping spring 103 is mounted inside the cylindrical buoy body 101, a damping ball 104 is mounted at the other end of the damping spring 103, the damping ball 104 is positioned in a center of the cylindrical buoy body 101, and a middle of an upper end of the cy- lindrical buoy body 101 is rotatably connected to the bidirection- al rack bar 2 through a bearing.
A middle and an end of the diverter 102 are arranged in a fin shape, and the end of the diverter 102 is arranged cambered from an end away from the cylindrical buoy body 101 to an end near the cylindrical buoy body 101, and an end surface, in contact with the cylindrical buoy body 101, of the diverter is also cambered.
Six diverters 102 are arranged, and a distance between an outermost end surface of the diverter 102 and a center line of the cylindrical buoy body 101 gradually decreases in a clockwise di- rection.
The damping springs 103 are mounted inside the cylindrical buoy body 101, four damping springs 103 are arranged, and the damping springs 103 are distributed around an outer side of the damping ball 104.
Based on the above technical solution, point A in the figure is an intersection of a left end of the cylindrical buoy body 101 and waterline. By analyzing force of point A, it can be known that when the waves impact on the cylindrical buoy body 101, force acts on an end surface of the cylindrical buoy body 101, a force- bearing surface of the cylindrical buoy body 101 may bear compo- nent force in a horizontal direction, that is, F,, which may cause radial force of the cylindrical buoy body 101, and further cause vibration of the apparatus. When impact in the horizontal direc- tion acts on the end surface of the cylindrical buoy body 101, ki- netic energy generated by impact stretches the damping spring 103, the kinetic energy is converted into elastic potential energy of the damping spring 103, thus partially consuming the kinetic ener- gy, and reducing the impact. Impact in the vertical direction on the cylindrical buoy body 101 is buffered per the same principle, thus making the cylindrical buoy body 101 move more smoothly, im- proving the reliability of a device and prolonging the service life of the device.
Embodiment 2
As shown in FIGs. 1-11, a hydrodynamic control system based on the Princeton Ocean Model includes an oscillating buoy 1, a bi- directional rack bar 2, a transmission mechanism 3, a coupling 4, a generator 5 and a mounting platform 6, the oscillating buoy 1 including a cylindrical buoy body 101 and diverters 102 distribut- ed around an outer side of the cylindrical buoy body 101, where a damping spring 103 is mounted inside the cylindrical buoy body 101, a damping ball 104 is mounted at the other end of the damping spring 103, the damping ball 104 is positioned in a center of the cylindrical buoy body 101, and a middle of an upper end of the cy- lindrical buoy body 101 is rotatably connected to the bidirection- al rack bar 2 through a bearing.
The transmission mechanism 3 includes an outer cylinder 301 and a driving gear 302, where an inner side of an end of the outer cylinder 301 is connected to the bidirectional rack bar 2 through a linear bearing, a middle inside the outer cylinder 301 is sym- metrically provided with driving gears 302 engaged with the bidi- rectional rack bar 2, the driving gear 302 is internally provided with an overrunning clutch 303, an output shaft 304 is mounted in- side the overrunning clutch 303, an outer side of the output shaft 304 is rotatably connected to the outer cylinder 301 through a bearing, the other end of the output shaft 304 is provided with a driven gear 305, an inner side of the driven gear 305 is meshed with a generator gear 306, an interior of the generator gear 306 is connected to an input end of the coupling 4, an output end of the coupling 4 is connected to a main shaft of the generator 5, and buffer springs 307 are symmetrically arranged inside the outer cylinder 301.
The transmission mechanism 3 and the generator 5 are fixed on the mounting platform 6, and a lower end of the mounting platform 6 is fixedly connected to a platform support 7, and a bottom end of the platform support 7 is fixed at seabed.
As shown in FIG. 11, based on the above technical solution: when waves impact on the cylindrical buoy body 101 at this angle, horizontal force of the waves is perpendicular to a median line of every two diverters 102, force acting on a surface of the cylin- drical buoy body 101 is uniform and equal, force acting on two ad-
Jacent diverters 102 on a left side may vary, force analysis is performed by letting the horizontal force of the waves be F:, tak- ing a midpoint of an end surface of an inner inside of the divert- er 102 located at an upper side in FIG. 11 as B, taking a midpoint of an end surface of an inner inside of the diverter 102 located at a lower side as C, as shown in FIG. (b) of FIG. 11, then force
F3 on point B may be divided into force F; parallel to a plane of point B and force Fj perpendicular to the plane of point B.
As shown in FIG. 11 (cc), force F; on point C may be divided into force F, parallel to a plane of point C and force F; perpen- dicular to the plane of point C.
As shown in FIG. 11 (d), the force diagram shows that there is a difference between the vertical component force of point B and point C. After the cylindrical buoy body 101 is regarded as a whole, the vertical component force of point B and point C may be vectorial resultant, so as to obtain F resultant force 1-
According to the force diagram, it can be known that there is a difference in direction between F esultant force ; and the force Fj.
Under the action of the force difference, the cylindrical buoy body 101 rotates, so part of the impact kinetic energy may be con- verted into kinetic energy of rotation of the cylindrical buoy body 101 itself, and vibration of the cylindrical buoy body 101 is reduced. An end of the diverter 102 is arranged cambered from an end away from the cylindrical buoy body 101 to an end near the cy- lindrical buoy body 101, and an end surface, in contact with the cylindrical buoy body 101, of the diverter 102 is also cambered, so the cylindrical buoy body 101 reciprocates in the vertical di- rection under the action of the waves and its own gravity, and a vertical component of wave energy may act in an effective contact area between the cylindrical buoy body 101 and the waves. The fin- shaped ends are arranged at an upper end and a lower end of the diverter 102, when the cylindrical buoy body 101 moves, the waves are diverted along fin-shaped edges of the ends, which reduces the effective contact area between the diverter 102 and the waves and may not affect movement in the vertical direction of the cylindri- cal buoy body 101.
