The rotation of the floating drop group drives the bevel gear 13 on the short shaft 12 to synchronously rotate, and the bevel gear 13 further drives the transmission rod 17 to rotate, so that the wave energy collected by the floating drop group is transmitted to the transmission rod 17.
In fig. 5a, the other end of the transmission rod 17 drives a first gear set and a second gear set through a bevel gear structure, wherein the first gear set is composed of a first gear 20 and a second gear 18; the second gear set consists of a first gear 21 and a second gear 19. The first gear 20 and the first gear 21 are straight gears respectively, the circumferential surfaces of the second gear 18 and the second gear 19 are provided with straight tooth structures which are meshed with the first gear 20 and the first gear 21 respectively, the side surfaces of the second gear 18 and the second gear 19 are provided with bevel tooth structures which are meshed with bevel gear structures of the transmission rod 17 respectively, further, sea wave energy transmitted to the transmission rod 17 is transmitted to the second gear 18 and the second gear 19, and the second gear 18 and the second gear 19 further transmit the sea wave energy to the transmission shaft 27 through the first gear 20 and the first gear 21 meshed with the second gear 18 and the first gear 21.

Similarly, when the floating drop set rotates in the second direction (anticlockwise), as shown in fig. 6b, the ocean wave energy is simultaneously transmitted to the second gear 18 and the second gear 19 through the bevel gear 13 and the transmission rod 17, and under the action of the unidirectional bearing 22, the second gear 18 is not rotatable, the second gear 19 synchronously rotates in the first direction (clockwise), the second gear 19 drives the first gear 21 meshed with the second gear 18 to rotate in the second direction (anticlockwise), and under the action of the inner meshed ratchet structure 23, the first gear 21 transmits the ocean wave energy to the transmission shaft 27 in the form of anticlockwise torque, so that the transmission shaft 27 rotates in the second direction to generate the second direction torque.
It should be noted that, the principle of setting the unidirectional bearing 22 and the ratchet structure 23 on the first gear set in the disclosure is to ensure that the directions of the torques finally transferred to the transmission shaft 27 are the same under the condition of not affecting the normal transmission, so as to avoid the waste of energy caused by the mutual offset of the torques due to opposite directions.
FIG. 4 is a schematic structural view of a pendulum rod of an embodiment of the present disclosure; as shown in fig. 4, the main body of the swing rod 6 is in an X shape, two split claws 14 are respectively arranged at two ends and used for connecting the short shaft 12 and the fixed shaft 28, the two split claws 14 at one end are positioned between the first gear set and the second gear set, and the two split claws 14 at the other end are positioned at two sides of the bevel gear 13 so as to adapt to the assembly of the first transmission mechanism 7; the joint of each claw 14, the short shaft 12 and the fixed shaft 28 is provided with a bidirectional bearing 15 to play a role in reducing friction loss; the main body of the swing rod 6 is provided with a groove 16 along the axial direction, the transmission rod 17 passes through the groove 16, and the arrangement of the groove 16 ensures that the installation of the swing rod 6 is not influenced while the wave energy of the transmission rod 17 is transmitted, thereby optimizing the assembly relation.
FIG. 7 is a block diagram of a second gear train of an embodiment of the present disclosure; as shown in fig. 7, the second transmission mechanism 8 includes a traction rope 25, the traction rope 25 is connected with a transmission shaft 27 through an automatic retraction mechanism, the automatic retraction mechanism includes a housing 24 with a rotating shaft, the rotating shaft is connected with the transmission shaft 27 through a one-way bearing 22, under the action of the automatic retraction mechanism, the traction rope 25 can be pulled out according to the length to be used, and the traction rope 25 can be automatically retracted into the housing 24 after use. The other end of the traction rope 25 is fixed on the swing rod 6, and an automatic retracting mechanism of the traction rope 25 is arranged between the first gear 20 and the first gear 21 of the driving shaft 27.
FIG. 8a is a block diagram of the assembly of pulleys, first gears, second gears, swing links, drive links, etc. according to an embodiment of the present disclosure; FIG. 8b is an enlarged view of a portion of FIG. 8 a; as shown in fig. 8a and 8b, a pulley 9 is further mounted on the fixed shaft 28 between the second gear 18 and the second gear 19, and a bidirectional bearing 15 is mounted between the pulley 9 and the fixed shaft 28 to ensure flexible rotation of the pulley 9; the pulley 9 is provided with a groove 26 on the outer surface, and the groove 26 of the pulley 9 can prevent the traction rope 25 from being extended too far to be clamped on the fixed shaft 28, so that the transmission of the first transmission mechanism 7 is influenced.
FIG. 9a is an illustration of pendulum motion of an embodiment of the present disclosure; FIG. 9b is an illustration of pendulum movement of a pendulum in an embodiment of the present disclosure; principle of collecting and transmitting longitudinal wave energy by the swing rod 6 and the second transmission mechanism 8: as shown in fig. 9a, when the swing rod 6 is driven to swing downwards by the wave energy in the form of longitudinal waves, under the action of the unidirectional bearing 22, the relative position of the rotating shaft and the main transmission shaft 27 is fixed at this moment, the motion state is consistent, when the swing rod 6 moves to pull the traction rope 25 to the limit length, the swing rod 6 continues to swing downwards to drive the main transmission shaft 27 to rotate so as to generate torque, and the swing rod 6 and the second transmission mechanism 8 transmit the wave energy in the form of longitudinal waves to the transmission shaft 27 so as to generate torque in the same direction as the torque transmitted to the transmission shaft 27 by the first transmission mechanism 7. When the swing rod 6 swings upwards, a torque opposite to the direction of the swing rod during the swing down is generated, as shown in fig. 9b, the rotating shaft can rotate relative to the transmission shaft 27, the torque of the swing up cannot be transmitted to the transmission shaft 27, and meanwhile, the traction rope 25 automatically withdraws into the shell 24 to prepare for the swing down of the swing rod 6 next time.
As is well known, the torque generated by the floating drops and the sea wave energy collected by the swing rod 6, which is transmitted to the transmission shaft 7 through the first transmission mechanism 7 and the second transmission mechanism 8, is a low-speed large torque, and cannot be used for generating electricity. For this reason, the wave power generation device of the present disclosure also needs to convert the low-speed large torque.
In order to collect ocean wave energy to the maximum extent, the floating drop type ocean wave energy collecting modules 1 of the present disclosure include a plurality of floating drop type ocean wave energy collecting modules 1 distributed into four module groups, each module group is formed by connecting at least one floating drop type ocean wave energy collecting module 1 in series, that is, all floating drop type ocean wave energy collecting modules 1 of each module group share one transmission shaft 27, and the torque directions transmitted to the shared transmission shaft 27 by all floating drop type ocean wave energy collecting modules 1 in each module group are consistent. Then, the four module groups are continuously connected end to end in series to form a square plane which is perpendicular to each other; the drive shaft 27 of the tail module group is connected to the energy conversion module 3. Thus, the wave energy around the square plane can be collected.
Because the rotating shafts 27 between two adjacent module groups are perpendicular to each other, the torque directions of the rotating shafts 27 connected in series in a mutually perpendicular manner need to be converted, and therefore, the torque transmission module 2 is installed at the connecting end parts of the mutually perpendicular rotating shafts 27 connected in series to realize the reversing in the torque transmission process, namely, the torque transmission module 2 is responsible for continuously converting the low-speed large torque of the transmission shaft 27 of each module group from the head end direction, namely, the torque of the transmission shaft 27 is controlled to be transmitted according to a designated route, and finally, all the sea wave energy collected by the floating-drop sea wave energy collecting module 1 is transmitted to the energy conversion module 3.
FIG. 10a is a torque transfer module configuration diagram of an embodiment of the present disclosure; FIG. 10b is an enlarged view of a portion of FIG. 10 a; as shown in fig. 10a and 10b, the torque transmission module 2 of the present disclosure includes a bevel gear set 29, the bevel gear set 29 includes a first bevel gear and a second bevel gear, and the first bevel gear and the second bevel gear are respectively connected to ends of two transmission shafts 27 of two adjacent module sets; the first bevel gear and the second bevel gear are meshed with each other to change the transmission direction, and the change angle is 90 degrees.
FIG. 11 is a schematic view of the ocean wave energy transfer direction of an ocean wave energy generating device according to an embodiment of the present disclosure; as shown in fig. 11, the torque transmission module 2 of the present disclosure operates on the principle that: after the torque of the transmission shaft 27 in the head end direction is converted by the bevel gear set 29 by 90 degrees, the torque is changed into the torque in the same direction as the torque of the next transmission shaft 27 connected with the bevel gear set, so that the torque is overlapped, and the like, and finally, the torque of the transmission shafts 27 of all the module groups is sequentially transmitted to the energy conversion module (3), and finally, the energy convergence is realized.
Because the collected torques are low-speed large torques and need to be converted into high-speed small torques to be input into the generator for utilization, the output end of the transmission shaft 27 of the module group at the tail end is connected with the energy conversion module 3.
FIG. 12a is a block diagram of the connection of an energy conversion module to an ocean wave energy power plant in an embodiment of the present disclosure; FIG. 12b is an enlarged view of a portion of FIG. 12 a; as shown in fig. 12a and 12b, the energy conversion module 3 includes an acceleration gear set 30 and a generator 31. The accelerating gear set 30 is used for converting the low-speed large torque transmitted by the transmission shaft 27 into high-speed small torque and transmitting the high-speed large torque to the generator 31 for electric energy conversion, and finally converting sea wave energy into available electric energy.
