Description

Technical Field

[0001] The present invention relates to the technical fields of ocean engineering and renewable energy development and utilization, and particularly relates to an energy-gathering wave energy power generation system adaptable to water levels and an application method thereof. Background Art

[0002] Wave energy, as an important part of ocean energy, is a green renewable energy and also contributes to the transformation of the energy structure. Wave energy is extremely abundant in coastal and offshore areas, so wave energy has broad development space. The power generation process of wave energy devices mainly includes three stages: the incident wave acts on the wave energy device to make the wave energy device generate motion or enter the wave energy device to form a moving water column, forming the capture stage. Then, the mechanical energy is converted through the motion of the device or the air pressure formed by the motion of the water column inside the device through a connecting rod or a turbine, forming the energy conversion and transmission stage. Finally, the mechanical energy is converted into electrical energy through a generator and finally output in the form of electrical energy. However, the low wave energy flux density and the obvious difference in spatial distribution lead to the low efficiency of existing wave energy devices, resulting in low economy. Moreover, the input wave energy of existing wave energy power generation devices is relatively single, only absorbing the energy of incident waves, and even unable to generate electricity in areas with low energy flux density. Even if the wave energy devices are arranged in an array, the problems of low efficiency and low economy cannot be solved, and the shielding effect between the power generation units of the array also causes the overall efficiency of the wave energy device array to be much lower than that of a single wave energy device. In addition, due to the ocean tidal range, the water surface height changes, and most existing wave energy devices are fixed. Therefore, when the water surface height is too low, the wave cannot act on the wave energy device; when the water surface height is too high, the wave submerges the wave energy device, resulting in the failure of the wave energy device.

[0003] Based on the above problems, there is an urgent need to design an energy-gathering wave energy power generation system that can adjust its position according to the change of tidal range, avoid the failure of wave energy devices, and avoid the shielding effect generated after the wave energy device array.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Example 1: Refer to the appendix Figures 1 - 9 , a water-level adaptable concentrated wave energy power generation system, comprising a plurality of wave energy devices, each of which is composed of a wave energy capture device 4 and a wave energy power generation device 5. The wave energy power generation device 5 is installed on the upper part of the wave energy capture device 4. The wave energy devices adopt an oscillating water column type wave energy capture device 4 and wave energy power generation device 5. The main design point of this system lies in: The wave energy converging device 2 is composed of a plurality of energy concentrating plates 3 spliced together. The wave energy converging device 2 formed by splicing a plurality of energy concentrating plates 3 in sequence is in a parabolic shape. Two fixed card slots 18 are opened on one side of the wave energy converging device 2. The fixing frame 11 is clamped in the two fixed card slots 18. A plurality of anchoring nails 17 are fixedly connected in the fixed card slots 18. A plurality of anchoring holes matching with the anchoring nails 17 are opened on the side wall of the fixing frame 11. Two limiting card strips 16 are arranged on one side of the energy concentrating plate 3. A plurality of rubber sheets 19 are fixedly connected to one side of the fixing frame 11. The rubber sheets 19 are located between two adjacent rectangular plates 3. A plurality of connecting rods 6 are fixedly connected to one side of the wave energy device. One ends of the plurality of connecting rods 6 are all fixed on one side of the wave energy converging device 2. A plurality of wave energy devices are arranged in an array in the opening area of the wave energy converging device 2. One wave energy converging device 2 and a plurality of wave energy devices form a power generation unit. The wave energy capture device 4 is an oscillating water column type wave energy capture device 4, and the wave energy power generation device 5 is an oscillating water column type wave energy power generation device 5. After the incident wave moves to the wall surface of the wave energy converging device 2, a reflected wave with a direction different from that of the incident wave is generated. Based on the reflection effect of the wave energy converging device 2 on the wave, using the parabolic shape of the wave energy converging device 2, reflected waves can be generated in multiple directions, so as to move in the opposite direction to the incident wave and superimpose at a specific position, enabling the wave energy to converge at this position. The number and installation position of the energy concentrating plates 3 can be adjusted according to the actual sea conditions. When the wave energy flux density of the actual sea conditions is low, adjust the installation position of the energy concentrating plates 3 and design different curvatures during production, so that the concavity and convexity of the parabolic wave energy converging device 2 formed by the energy concentrating plates 3 are reduced, thereby improving the wave energy converging effect. When the wave energy flux density of the actual sea conditions is relatively high, increase the number of the energy concentrating plates 3, so that the chord length of the parabolic wave energy converging device 2 formed by the energy concentrating plates 3 is increased, thereby increasing the wave energy converging position. At the specific position where the wave energy converges, a plurality of wave energy devices are fixedly connected to the wave energy converging device 2 through the connecting rods 6, so that the wave energy in multiple directions after convergence can be captured and absorbed by the oscillating water column type wave energy capture device 4, and then be converted into electric energy by the oscillating water column type wave energy power generation device 5, significantly improving the power output and conversion efficiency of the wave energy device and avoiding the shielding effect that appears between a plurality of wave energy devices in the array.

[0022] The lifting and adjusting mechanism is configured with multiple pile legs 1. A cross bar 12 is commonly connected to the side walls of the multiple pile legs 1. The lower ends of the pile legs 1 are each provided with a base 13, and the bases 13 are installed on the seabed. The lifting and adjusting mechanism is used to control the longitudinal position adjustment of the wave energy converging device 2. One side of the lifting frame 9 is connected to the lifting and adjusting mechanism, and a fixing frame 11 is installed on the other side of the lifting frame 9. One side of the wave energy converging device 2 is installed on the fixing frame 11. A water surface monitoring device 10 is fixedly connected to the upper part of the fixing frame 11, and the water surface monitoring device 10 controls the start and stop of the lifting and adjusting mechanism.

[0023] Since the opening area of the wave energy converging device 2 is the wave energy converging area, where the water surface height changes violently and cannot accurately reflect the change of the tidal range, the water surface monitoring device 10 monitors the change of the water surface height on the back side of the opening area of the wave energy device 2. According to the change of the tidal range of the sea surface, when the water surface monitoring device 10 monitors that the water surface on the back side of the opening area of the wave energy converging device 2 drops, it controls the start of the power mechanism, the driving motor 8 rotates forward, drives the lifting and adjusting mechanism to rotate forward through the coupling, so that the lifting frame 9 drives the wave energy converging device 2 to synchronously descend to the sea level position with the wave energy device. After the descent is completed, the water surface detection device 10 controls the stop of the power mechanism; when the water surface monitoring device 10 monitors that the water surface on the back side of the opening area of the wave energy converging device 2 rises, it controls the start of the power mechanism, the driving motor 8 rotates in reverse, drives the lifting and adjusting mechanism to rotate in reverse through the coupling, so that the lifting frame 9 drives the wave energy converging device 2 to synchronously rise to the sea level position with the wave energy device. After the rise is completed, the water surface detection device 10 controls the stop of the power mechanism; after completing the longitudinal position adjustment of the wave energy converging device 2 according to the change of the tidal range, the wave energy converging device 2 continues to converge the wave energy at a specific position, so that multiple wave energy devices arranged at this position perform wave energy power generation work, avoiding that the waves cannot act on the wave energy devices due to too low water surface, resulting in the wave energy not being captured, absorbed and converted by the wave energy capture device 4 and the wave energy power generation device 5; or that the waves submerge the wave energy devices due to too high water surface height, resulting in the failure of the wave energy devices to work, and at the same time reducing the construction and maintenance costs of the wave energy converging device 2.

[0024] As Figure 9 shown, the parabolic structures of the wave energy converging device 2 designed in this technical solution have two types; One is to adopt an asymmetric parabolic structure. When adopting the asymmetric parabolic structure, multiple wave energy devices are still arranged according to the wave energy convergence focus of the opening area of the wave energy converging device 2, and can be uniformly adjusted according to requirements; Second, a symmetric parabolic structure is adopted. According to the characteristics of the parabolic shape, there is a converging focus, and the optimal energy-concentrating effect is at the focus. The first wave energy device is arranged here. Also, due to the symmetry of the parabolic shape, but there is only one focus, so there are two wave energy devices arranged at other energy-concentrating positions, both symmetrically arranged with respect to the symmetry axis of the wave energy converging device 2. Except for the wave energy device at the focus position, the remaining wave energy devices are symmetrically arranged according to the parabolic structure. In addition, the chord length and radian of the wave energy converging device 2 can be designed by adjusting the number and radian of the energy-concentrating plates 3 to achieve the controllable and adjustable characteristics of the wave energy converging effect according to the wave energy flux density under different sea conditions. Then, the number of wave energy devices 2 is adjusted and arranged according to the abundance of wave energy and the wave energy converging effect, so as to maximize the economy of the wave energy power generation system.

[0025] Obviously, the wave energy converging device 2 can be regularly arranged on the seabed in a matrix form, such as Figure 7 and Figure 8 shown. Similarly, it can also be arranged individually or in multiple irregular ways according to the actual situation (not shown in the drawings).

[0026] Through the superposition and convergence of waves by the wave energy converging device 2 in this technical solution, the convergence of wave energy at a specific position is realized, significantly improving the wave energy level captured and converted when the wave energy device and its array are arranged, greatly increasing the power output and conversion efficiency of the wave energy device, and at the same time avoiding the shielding effect when the wave energy device array is arranged. Secondly, a lifting and adjusting mechanism is arranged at the rear of the wave energy converging device 2. When the tidal difference occurs, the position of the energy-concentrating wave energy power generation system can be adjusted, so that the energy-concentrating wave energy power generation system is not affected by the change of tidal difference, and maintains the wave energy power generation function under the water surface height conditions at any season and time, avoiding the failure of the energy-concentrating wave energy power generation system and reducing the construction and maintenance costs of the wave energy converging device at the same time. The wave energy converging device 2 is composed of multiple spliced energy-concentrating plates 3, and the number and installation position of the energy-concentrating plates 3 can be adjusted according to the actual sea conditions, increasing the controllability of the wave energy converging effect of the wave energy converging device 2.

[0027] Embodiment 2: Different from Embodiment 1; Refer to the attached Figures 4 - 5, One side of the fixing frame 11 is rotatably connected with a plurality of elastic struts through a rotating shaft. One end of each of the plurality of elastic struts away from the fixing frame 11 is sleeved with a fixing bolt through a fixing hole. A plurality of threaded holes are formed in the side wall of the lifting frame 9. The fixing bolt is connected to one of the threaded holes. The middle of the fixing frame 11 is rotatably connected to the side wall of the fixing frame 11 through a main shaft. The elastic strut includes a head 14 and a rectangular tube 15. One end of the head 14 is rotatably connected to the fixing frame 11 through a rotating shaft. One end of the head 14 is fixedly connected with a rectangular rod 20. One end of the rectangular rod 20 extends into the rectangular tube 15 and is fixedly connected with a spring 22. One end of the spring 22 is fixed inside the rectangular tube 15. A strip-shaped hole is formed in the rod wall of the rectangular rod 20. A positioning post 21 is sleeved in the strip-shaped hole. The positioning post 21 is fixed inside the rectangular tube 15.

[0028] It is recommended that the size of the spring 22 be a compression spring with a free length of 50 - 60 cm, an outer diameter of 20 - 25 cm, and a wire diameter of 2.5 - 3.5 cm.

[0029] When the wave energy converging device 2 in front of the fixing frame 11 is impacted by large waves, the spring 22 can have a certain amount of expansion and contraction between the rectangular rod 20 and the rectangular tube 15. The amount of expansion and contraction depends on the strip-shaped hole on the rectangular rod 20, and the expansion range is 0 - 10 cm. At the same time, in order to cope with the impact of small waves, during assembly, it is necessary to first compress the spring 22 by 2 - 4 cm of its free length. In this way, after the spring 22 is compressed, small waves cannot impact the wave energy converging device 2 to cause displacement. When impacted by large waves, since the compression length of the spring 22 is limited (i.e., within 10 cm), therefore, after reaching the compression limit, the elastic support automatically converts to a rigid support. Therefore, the wave energy converging device 2 can have a certain buffer and compressive capacity, minimizing the possibility of damage caused by wave impact.

[0030] As Figure 5 shown, when the rectangular tube 15 is installed on the threaded holes at different positions of the lifting frame 9 through the fixing bolt, the lifting frame 9, the wave energy converging device 2, and the fixing frame 11 can achieve multi-angle adjustment. In this way, it is convenient to finely adjust the angle of the wave energy converging device 2 during laying.

[0031] Embodiment 3: The difference from Embodiment 1 is that; Refer to the attached Figure 6, The lifting and adjusting mechanism includes a housing 7, which is fixed to the upper end of the lifting frame 9. A transmission shaft 29 is rotatably connected to the housing 7 through a first sealing bearing. A plurality of threaded portions 28 are provided on the shaft wall of the transmission shaft 29, and a plurality of worm wheels 25 are engaged with the plurality of threaded portions 28. The lower end of the housing 7 is rotatably connected to a plurality of lead screws 23 through a second sealing bearing. A first bearing seat is rotatably connected to the rod wall of each of the plurality of lead screws 23, and the first bearing seat is fixed to the side wall of the lifting frame 9 by screws. The upper end of the lead screw 23 is fixedly connected to the lower end of the worm wheel 25. The pile leg 1 is of a tubular structure. A threaded sleeve 24 is threadedly connected to the rod wall of the lead screw 23, and the threaded sleeve 24 is fixed to the inner edge of the upper opening of the pile leg 1. The lower end of the lead screw 23 extends into the pile leg 1 and is rotatably connected to a cylinder 30 through a ball bearing. A power mechanism for driving the rotation of the transmission shaft 29 is installed at the upper end of the housing 7; The power mechanism includes a first bevel gear 26, which is fixed to the shaft wall of the transmission shaft 29. A second bevel gear 27 is engaged with one side of the first bevel gear 26. A driving motor 8 is fixedly connected to the upper end of the housing 7. The output shaft of the driving motor 8 is connected to a connecting shaft through a coupling. The shaft wall of the connecting shaft is rotatably connected to the upper end of the housing 7 through a ball bearing. The lower end of the connecting shaft is coaxially and fixedly connected to the upper end of the second bevel gear 27. A plurality of second bearing seats are rotatably connected to the shaft wall of the transmission shaft 29, and the second shaft seats are fixed inside the housing 7.

[0032] When the sea conditions change, the control host (not shown in the figure) controls the driving motor 8 through the electrical signal monitored by the water surface monitoring device 10 to rotate the connecting shaft. This technology has been widely used in life and is already known to those skilled in the art, so no more details will be given. When the connecting shaft rotates, it drives the second bevel gear 27 to rotate the first bevel gear 26. When the first bevel gear 26 rotates, it drives the transmission shaft 29 to rotate the spiral portion 28. When the spiral portion 28 rotates, it drives the worm wheel 25 to rotate the lead screw 23. When the lead screw 23 rotates in the threaded sleeve 24, the lead screw 23 moves by using the interaction between the threads. In this way, it can be realized that the lead screw 23 drives the housing 7 to move the lifting frame 9 and the wave energy converging device 2 longitudinally. In addition, due to the interlocking characteristics between the lead screw 23 and the threaded sleeve 24 and between the spiral portion 28 and the worm wheel 25, the lifting and adjusting device can be realized to have the self-locking characteristic.

[0033] The application method of this power generation system is as follows: S1. Use the water surface monitoring device 10 to monitor the change of the sea surface height to control the start of the power mechanism. The driving motor 8 drives the lifting and adjusting mechanism through the coupling, so that the lifting frame 9 and the fixedly connected wave energy converging device 2 move to the water surface height position; S2. The wave energy converging device 2 completes the wave energy convergence at a specific position in the opening area of the wave energy converging device 2 through the superposition effect on the waves; S3. At a specific wave energy convergence position, arrange wave energy devices according to the wave energy level, so that the converged wave energy is absorbed by the wave energy capture device 4, and then further converted by the wave energy power generation device 5 fixedly connected to the upper part of the wave energy capture device 4; S4. The hydrodynamic interaction between the wave energy convergence device 2 and the wave energy devices causes the evolution of the wave energy convergence process and converges the wave energy at a new specific position; S5. At the new specific wave energy convergence position, continue to arrange wave energy devices according to the wave energy level, so that the converged wave energy is absorbed by the wave energy capture device 4, and then converted by the wave energy power generation device 5 fixedly connected to the upper part of the wave energy capture device 4.

[0034] When performing S3, under the combined action of the first wave energy device and the wave energy convergence device 2, new wave energy convergence positions are generated by the waves and are absorbed by the second wave energy device arranged there, so as to repeat steps S4 to S5; When the sea surface height drops, the driving motor 8 rotates forward, drives the lifting adjustment mechanism to rotate forward through the coupling, and makes the lifting frame 9 drive the wave energy convergence device 2 to descend to the sea level position. When the sea surface height rises, the driving motor 8 rotates reversely, drives the lifting adjustment mechanism to rotate forward through the coupling, and makes the lifting frame 9 drive the wave energy convergence device 2 to descend to the sea level position.

[0035] It should be noted that the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
