Therefore, when the float 30 moves upward, the sliding rod 23 will follow the upward movement and simultaneously drive the first transmission rod 21 and the second transmission rod 22 to move upward, and similarly, when the float 30 moves downward, the sliding rod 23 will follow the downward movement and simultaneously drive the first transmission rod 21 and the second transmission rod 22 to move downward, and the rotation of the first transmission rod 21 and the second transmission rod 22 will provide power for the hydraulic power generation mechanism 40.

In the illustrated direction, if the second transmission shaft 252 rotates clockwise, the second rocker 521 drives the longer second pawl 522 to separate from the second ratchet 523 and drives the shorter second pawl 522 to engage with the second ratchet 523, and if the second transmission shaft 252 rotates counterclockwise, the second rocker 521 drives the longer second pawl 522 to engage with the second ratchet 523 and drives the shorter second pawl 522 to separate from the first ratchet 523, and both rotation modes can push the second ratchet 523 to rotate clockwise, and the second driving wheel 524 can rotate synchronously at this time, so as to drive the second driven wheel 525 and the second output shaft 526 to rotate, thereby implementing power output.
As shown in fig. 4 to 6, the hydraulic power generation mechanism 40 includes a hydraulic cylinder 41, a first hydraulic pump 421, a second hydraulic pump 422, a first direction changing valve 431, a second direction changing valve 432, an energy storage device 44, a hydraulic motor 45, and a generator 46; the hydraulic cylinder 41 is provided with a first liquid changing end 411 and a second liquid changing end 412; the first hydraulic pump 421 obtains power from the first one-way transmission mechanism 51, and the output end of the first hydraulic pump 421 is connected with an overflow valve 47, a throttle valve 48 and a first reversing valve 431; the throttle valve 48 is connected between the first liquid changing end 411 and the output end of the first hydraulic pump 421; the first built-in passage of the first reversing valve 431 is communicated between the second liquid changing end 412 and the first built-in passage of the second reversing valve 432, and the second built-in passage of the first reversing valve 431 is communicated between the second liquid changing end 412 and the output end of the first hydraulic pump 421; the built-in passage I of the second reversing valve 432 is communicated between the built-in passage I of the first reversing valve 431 and the input end of the energy storage device 44, and the built-in passage II of the second reversing valve 432 is in idle connection; the second hydraulic pump 422 obtains power from the second one-way transmission mechanism 52, the output end of the second hydraulic pump 422 is connected with the unloading valve 49 and the one-way valve 410, the output end of the second hydraulic pump 422 is connected and communicated with the output end of the first hydraulic pump 421 through the one-way valve 410, and the one-way valve 410 is used for being communicated when the output pressure of the second hydraulic pump 422 is sufficient; the output of the energy storage device 44 is connected to the input of a hydraulic motor 45, and the output of the hydraulic motor 45 is connected to the input of a generator 46.
Assuming that the float 30 is in the ascending state, the first direction changing valve 431 and the second direction changing valve 432 are in the state shown in fig. 6, that is, the built-in passage of the first direction changing valve 431 and the built-in passage of the second direction changing valve 432 are both in the conducting state, so that the first hydraulic pump 421 and the second hydraulic pump 422 can drive the hydraulic oil to flow to the throttle valve 48; however, under the flow limiting effect of the throttle 48, the simultaneous operation of the two hydraulic pumps will increase the pressure in the pipeline, and when the pressure exceeds the preset values of the unloading valve 49 and the overflow valve 47, the unloading valve 49 and the overflow valve 47 will be opened, so that the second hydraulic pump 422 cannot generate enough pressure to flush the check valve 410, and the check valve 410 is in a closed state; therefore, at this time, the hydraulic oil is driven to flow only by the first hydraulic pump 421, the hydraulic oil enters the hydraulic cylinder 41 through the throttle valve 48 and the first switching end 411, so as to drive the piston of the hydraulic cylinder 41 to move slowly to the right, and the movement of the piston also drives the hydraulic oil to flow through the first reversing valve 431 and the second reversing valve 432 to enter the energy storage device 44, so as to drive the hydraulic motor 45 and the generator 46 to work, thereby generating electricity.
On the other hand, when the float 30 is in the descending state, the first built-in passage of the first direction changing valve 431 and the first built-in passage of the second direction changing valve 432 are both in the closed state, and the second built-in passage of the first direction changing valve 431 and the second built-in passage of the second direction changing valve 432 are in the conductive state, so that the liquid oil can enter the hydraulic cylinder 41 through the second built-in passage of the first direction changing valve 431 and the second liquid changing end 412, thereby driving the piston of the hydraulic cylinder 41 to move leftward rapidly, and realizing the backflow of the liquid oil.
Note that the first hydraulic pump 421 of this embodiment is preferably a high-pressure small-flow hydraulic pump, and the second hydraulic pump 422 is preferably a low-pressure large-flow hydraulic pump; the switching of the working modes of the first reversing valve 431 and the second reversing valve 432 is controlled by the wave energy power generation cultivation ship, and particularly, a position sensor can be arranged on the link mechanism 20, so that the wave energy power generation cultivation ship can know the motion state of the link mechanism 20 according to the detection result of the position sensor and control the first reversing valve 431 and the second reversing valve 432 to switch the built-in circuit.
As shown in fig. 3, a cone 31 is projected from the bottom of the float 30.
After the structure is adopted, namely the bottom of the floater 30 is formed by rotating the arc curve, the appearance design can effectively inhibit the pitching and surging motions of the floater, so that the heaving motion is strengthened, and the floater has better hydrodynamic performance.
As shown in fig. 1 and 2, the floating platform 10 has a frame structure, a plurality of buoyancy chambers 12 are provided inside the floating platform 10, and the floating platform 10 is provided with diagonal support columns 13 at positions surrounding the buoyancy chambers 12.
After adopting this structure, the oblique support column 13 can strengthen the stable in structure of the floating platform 10 to satisfy the user demand of various adverse circumstances.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
