Description

Technical Field

[0001] The invention relates to the technical field of wave energy power generation, in particular to a floating wave energy power generation device with a variable energy capture structure and a controllable energy conversion system. Background Art

[0002] As the global non-renewable energy is becoming increasingly depleted and the environmental pollution problem is becoming increasingly serious, the development and utilization of renewable clean energy has received widespread attention. my country has abundant marine energy resources, among which wave energy, as a new type of renewable green energy, has been widely studied due to its advantages of being pollution-free, renewable, with large reserves and wide distribution.

[0003] In order to develop and utilize ocean wave energy resources, wave energy power generation devices came into being. Oscillating float wave energy generation devices are one form of wave power generation. Oscillating float wave energy generation devices capture wave energy by moving the float up and down with the waves in the sea water, and then convert the mechanical energy of the float into electrical energy. Among various wave energy generation devices, the oscillating float wave energy generation device has been widely studied due to its good reliability.

[0004] The wave energy capture system and the energy transfer system are important links that determine the efficiency of power generation. Most of the current wave energy power generation devices have problems such as low efficiency, complex device structure, high cost, and difficult maintenance, which makes the economic benefits of wave energy power generation devices low and difficult to achieve industrial development. For example, the invention patent with patent publication number CN105888952A discloses an oscillating float type ocean wave energy power generation device, which converts the up and down reciprocating motion of the waves into the rotation of the main shaft through a sprocket chain transmission, and the main shaft is then connected to the energy storage flywheel for power generation. Another example is the invention patent with patent publication number CN112594119A, which discloses an oscillating float type wave energy power generation device, which adopts a slide rail mechanism and a rack transmission mechanism, and connects the float slide rail with the rack to make the rack do horizontal reciprocating linear motion, and then converts it into a unidirectional rotational motion of the generator, thereby completing the power generation and storage process.

[0005] Therefore, the existing floating power generation inevitably relies on the change of waves. When the waves are small, the relative movement amplitude between the floating body and the entire float is small. It is difficult to ensure the continuity of power generation of the generator by only using the energy conversion method of hydraulic transmission, and the power generation efficiency is low. When the waves are large, the relative movement amplitude between the floating body and the entire float is large, and the float cannot reduce the impact load. If only the energy conversion method of mechanical transmission is used, the gear box failure rate is high, and it is also easy to cause the float to be damaged due to the large impact between the floating body and the entire float. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, the present invention provides a floating wave energy power generation equipment with a variable energy capture body structure and a controllable energy conversion system. The equipment has a reasonable structural design and adopts mechanical and hydraulic transmission energy conversion methods. The energy conversion method of the power generation equipment can be changed in time according to the wave conditions. Under normal wave conditions, a mechanical and hydraulic hybrid transmission method is adopted to effectively improve the transmission efficiency, thereby increasing the utilization rate of wave energy and increasing the power generation; under extreme wave conditions, the floating body dives below the sea surface, thereby effectively reducing the impact load on the oscillating floating body and avoiding excessive impact on the equipment.

[0030] Optionally, the transmission assembly includes a gear box 17 movably sleeved on the cylinder barrel of the bidirectional hydraulic cylinder 11, the gear box 17 is arranged between the two tooth plates 14, and channels 18 are respectively provided on the left and right sides of the gear box 17, and transmission members are symmetrically provided on the left and right sides of the gear box 17, and the transmission members include an external gear 19, and the external gear 19 is movably clamped in the gear box 17 through a gear shaft 20, and an internal gear 21 sleeved on the gear shaft 20 is provided on the rear side of the external gear 19, and the internal gear 21 passes through the channel on the corresponding side of the gear box 17 18, meshed with the toothed plate 14 on the corresponding side, an overrunning clutch 22 and an electromagnetic clutch 23 are provided in sequence on the gear shaft 20 between the external gear 19 and the internal gear 21; a linkage gear 24 is provided between the two transmission members, the linkage gear 24 is respectively meshed with the external gears 19 on both sides, the linkage gear 24 is movably connected to the inner wall of the gear box 17 through a linkage gear shaft 25, a driving bevel gear 26 is sleeved on the linkage gear shaft 25, and a driven bevel gear 27 meshed with the driving bevel gear 26 is provided at the upper end of the output rod 16.

[0031] Optionally, the first power generation assembly includes a first generator 28 disposed in the power generation cabin 2, and the output shaft of the first generator 28 is connected to the lower end of the output rod 16 via a gearbox 29 and a commutator 30 in sequence. The electric energy generated by the first generator 28 is stored by an energy storage device and supplies energy to other components of the equipment.

[0032] Optionally, the hydraulic transmission energy conversion mechanism includes an oil tank 31 arranged on the upper support plate 12, the oil inlet nozzle on the cylinder barrel of the two-way hydraulic cylinder 11 is connected to the oil tank 31 through a pipeline, a second generator 32 is arranged in the power generation cabin 2, the second generator 32 is connected to a hydraulic motor 33, and the hydraulic motor 33 is connected to the oil outlet nozzle on the cylinder barrel of the two-way hydraulic cylinder 11 through a hydraulic pipeline 34. The electric energy generated by the second generator 32 is stored by an energy storage device and supplies energy to other components of the equipment.

[0033] Optionally, the resistance adjustment assembly includes a damping plate 35 arranged on the outside of the bottom frame 4, the damping plate 35 is movably hinged to the side wall of the bottom frame 4 through hinge seats 36 on the left and right sides of the inner wall, and a long hydraulic cylinder 37 is arranged on the side wall of the bottom frame 4 above the damping plate 35, the cylinder barrel of the long hydraulic cylinder 37 is connected to the side wall of the bottom frame 4 through an inner hinge seat 38, and the piston rod end of the long hydraulic cylinder 37 is connected to the damping plate 35 through an outer hinge seat 39. The resistance adjustment assembly can adjust the inclination angle of each damping plate 35 at any time according to the size of the wave to ensure the stability of the entire equipment. Under normal wave action, the long hydraulic cylinder 37 drives the damping plate 35 to open it to a horizontal position (perpendicular to the side wall of the bottom frame 4), achieving maximum self-damping while reducing the movement of the upper buoy 1, the power generation cabin 2 and the lower buoy 3 in the water, thereby increasing the relative movement between the guide column 7 and the floating body 6, which is beneficial to improving the energy capture efficiency; in extreme weather, the long hydraulic cylinder 37 drives the damping plate 35 to rotate it to a vertical direction (i.e., parallel to the side wall of the bottom frame 4), achieving minimum self-damping while increasing the movement of the upper buoy 1, the power generation cabin 2 and the lower buoy 3 in the water, thereby reducing the relative movement between the guide column 7 and the floating body 6 and reducing the impact on the equipment. The long hydraulic cylinder 37 can directly use the energy storage device of the equipment as a power support without the need for an external power source.

[0034] Optionally, the floating body 6 includes a float 601 movably sleeved on the upper buoy 1, a steel sleeve 602 is respectively provided at the upper and lower ends of the inner wall of the float 601 and is clamped with the outer wall of the upper buoy 1, and an inflatable airbag 603 sleeved on the outer side of the float 601 is provided; each of the guide columns 7 movably passes through the float 601, and the gantry 10 is arranged on the float 601. The air pump is powered by the energy storage device, so that the air pump can inflate and deflate the inflatable airbag 603. Under the action of waves, the float 6 reciprocates up and down along the two guide columns 7, converting the captured wave energy into mechanical energy. Under normal circumstances, the inflatable airbag 603 is in a fully inflated state, thereby increasing the contact area and buoyancy between the float 6 and the water surface, while the equipment remains stable, the average density of the float 6 is reduced, which is beneficial to improving the utilization rate of wave energy; in extreme weather, the inflatable airbag 603 is deflated, so that the average density of the float 6 increases and dives below the sea surface, while the upper buoy 1 always floats above the sea surface, thereby reducing the impact load on the float 6. In this way, the equipment can be reduced from being damaged by the violent sinking and floating of the float 6, effectively preventing the equipment from being subjected to excessive impact.

[0035] Optionally, the base frame 5 includes several layers of base plates 501 fixedly sleeved on the outer wall of the lower buoy 3, and support rods 502 are provided at the four corners of the bottom of the upper base plate 501, and each support rod 502 passes downward through other layers of base plates 501 and is connected to the bottom frame 4.

[0036] Under normal wave action, the electromagnetic clutch 23 of this equipment is in a coupled state, and the mechanical transmission method adopted in the equipment is as follows: the floating body 6 floats upward under the action of waves, and then pulls the piston cylinder of the two-way hydraulic cylinder 11 upward through the gantry 10, and the piston rod drives the toothed plates 14 on both sides to move upward through the connecting rod 15. As the right toothed plate 14 moves upward, the internal gear 21 meshing with it is driven to rotate counterclockwise, and the internal gear 21 drives the overrunning clutch 22 on this side to rotate in the same direction through the gear shaft 20, and the overrunning clutch 22 drives the external gear 19 connected to it to rotate counterclockwise, and then drives the interlocking gear 24 meshing with it to rotate clockwise (while the external gear 19 on the left side is idle under the action of the overrunning clutch 22 on the left side, that is, the external gear 19 driven by the left toothed plate 14 does not rotate, and can only rotate counterclockwise with the rotation of the interlocking gear 24), and the interlocking gear 24 is transmitted to the driven bevel gear 27 through the driving bevel gear 26, and then the output rod 16 is rotated, thereby supplying energy to the first generator 28 through the commutator 30 and the gearbox 29, generating electricity and storing it in the energy storage device. When the floating body 6 floats downward under the action of the waves, the transmission assembly on the left side is activated, so that the output rod 16 continues to rotate, so that the first generator 28 continues to generate electricity. During the repeated actions of the bidirectional hydraulic cylinder 11, the hydraulic transmission energy conversion mechanism causes the hydraulic oil to continuously reciprocate between the oil tank 31 and the hydraulic motor 33, causing the hydraulic motor 33 to continuously rotate, thereby providing power for the second generator 32 to generate electricity and store it in the energy storage device.

[0037] In extreme weather, as the inflatable airbag 603 in the float 6 is continuously deflated, the density of the float 6 is greater than the density of seawater, so that the float 6 dives below the sea surface. At this time, the electromagnetic clutch 23 is cut off, and the equipment only adopts the hydraulic transmission energy conversion method. As the float 6 floats up and down in the seawater, the gantry 10 drives the two-way hydraulic cylinder 11 to move, so that the hydraulic oil in the two-way hydraulic cylinder 11 continuously flows back and forth in the hydraulic motor 33, thereby continuously providing power for the second generator 32, and then storing electrical energy in the energy storage device. It has a reasonable structural design and adopts mechanical and hydraulic transmission energy conversion mechanisms. Under normal wave conditions, it adopts a mechanical and hydraulic hybrid transmission method to effectively improve the transmission efficiency, thereby increasing the utilization rate of wave energy and increasing the power generation; under extreme wave conditions, the equipment can be submerged below the sea surface, thereby reducing the impact load on the oscillating float, avoiding excessive impact on the equipment, improving the reliability of the equipment, and extending the life cycle of the equipment, solving the problems existing in the prior art.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents.
