Description

Technical Field

[0001] The utility model relates to the technical field of ocean kinetic energy utilization, in particular to an energy storage flywheel and a wave energy power generation device. Background Art

[0002] Ocean energy is a renewable clean energy source hidden in the ocean, mainly including tidal energy, tidal current energy, ocean current energy, wave energy, temperature difference energy and salinity difference energy. According to estimates, the theoretical renewable power of various ocean energies in the world is about 76.6 billion kilowatts, and the technically exploitable power is about 6.4 billion kilowatts, which is equivalent to twice the total number of generators in the world. According to the International Energy Agency's Ocean Energy Implementation Agreement, by 2050, the global installed capacity of ocean energy will reach 748 million kilowatts, and carbon dioxide emissions will be reduced by 5.2 billion tons. Ocean energy will become an important part of future energy supply and an important growth point for the future marine economy.

[0003] The wave energy power generation process is a very complex and multidisciplinary problem. The randomness of waves causes unstable energy flow, making it difficult to determine the design points of each level of conversion of wave energy power generation devices; the multi-directional reciprocating motion of waves also makes it difficult to design a reasonable energy capture system and power intake system; wave energy power generation devices work in the place where the waves are the largest, and the randomness and instability of waves lead to various sudden wave loads on wave energy power generation devices; corrosion and marine organism attachment caused by the harsh marine environment may cause failure of certain links of the device. Most of the current wave energy power generation devices have moving parts that are in direct contact with seawater, which are easily corroded by seawater and have low reliability.

[0004] It can be seen that the current wave energy power generation technology still has room for improvement, and should be adjusted and optimized to improve the conversion efficiency and reliability of wave energy power generation devices. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes an energy storage flywheel and a wave energy power generation device, which adjusts the structure of the energy storage flywheel and utilizes the lever arm principle to enable the flywheel to generate sufficient power and achieve a speed increase effect, thereby improving the power generation efficiency; at the same time, the structure of the power generation device is adjusted to isolate it from seawater to prevent erosion, follow the movement of ships, vessels and underwater ocean observation instruments, generate and store electrical energy through the swing of the energy storage flywheel, and provide electrical energy replenishment.

[0006] In order to achieve the above-mentioned purpose, the internal power generation device disclosed in the utility model can adopt the following technical solutions:

[0007] An energy storage flywheel comprises a swing arm, wherein a gear structure is arranged at the upper end of the swing arm and is used to transmit kinetic energy outward, and a pendulum structure is connected to the lower end of the swing arm; an axial hole for reciprocating deflection is arranged on the swing arm, and a swing force arm formed by the swing arm and the pendulum structure is greater than a force arm formed by the swing arm and the gear structure.

[0008] The energy storage flywheel disclosed above is used to follow the reciprocating swing in a shaking environment, and transmit the kinetic energy generated by the swing to the subsequent device, so as to drive the generator to work. The larger the difference in the length of the two force arms in the swing arm, the more it can capture the external shaking to convert the kinetic energy, and improve the smoothness of the swing, thereby improving the efficiency of power generation.

[0009] Furthermore, the structure of the swing arm can be constructed in a variety of forms. For example, a long straight arm can be used in some solutions. It is not limited to the only one. Here, an optimization is made and one of the feasible options is proposed: the width of the swing arm gradually increases from the upper end to the lower end, and the lower end of the swing arm forms a connecting plate for connecting the pendulum structure. When such a solution is adopted, the swing arm forms a triangular shape from top to bottom, and the weight of the lower end is greater than that of the upper end, which makes it easier to move the center of the swing arm downward, and form a larger swing force arm after cooperating with the pendulum, thereby helping to improve the efficiency of power generation.

[0010] Furthermore, the pendulum structure is used to increase the weight of the swing arm and lower the center of the swing arm, so that a greater torque is generated during the swing, thereby driving the subsequent device to generate electricity. The pendulum structure can be constructed in a variety of forms, which are not limited to the only one. Here, it is optimized and one of the feasible options is proposed: the pendulum structure includes a pendulum member, a connecting surface is formed on the pendulum member and is in contact with the connecting plate, and the connecting plate and the pendulum member are connected by fasteners. When such a solution is adopted, the thickness of the pendulum member is equivalent to that of the connecting plate, and bolts or the like can be used as fasteners for connection.

[0011] Furthermore, when setting the connection between the swing arm and the gear structure, they can be fixed by a variety of connection structures, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the upper end of the swing arm forms an arc surface, the gear structure includes a sector gear member and is connected to the arc surface, and the gear circle center of the sector gear member coincides with the center of the shaft hole. When such a solution is adopted, the sector gear member and the swing arm can be fixed by bolts, welding, etc.

[0012] The above content describes the structure of the energy storage flywheel. The utility model also discloses a power generation device, which generates electricity by utilizing the swing of the energy storage flywheel as a driving force. The details are described below.

[0013] A wave energy power generation device, using the energy storage flywheel described above, comprises:

[0014] The driving part is used to swing according to the shaking and transfer kinetic energy to the speed increasing part; the driving part includes a closed driving box, in which an energy storage flywheel is arranged, and the energy storage flywheel cooperates with the gear shaft and transfers kinetic energy to the outside;

[0015] The speed increasing part is used to transfer the kinetic energy of the driving part to the power generation part; the speed increasing part comprises a transmission input shaft, a speed increasing gear pair and a transmission output shaft, the transmission input shaft is connected and matched with the gear shaft, and the transmission output shaft is connected and matched with the power generation part;

[0016] The power generation unit includes a generator, and the motor shaft of the generator is driven by the transmission output shaft, and the power output end of the generator is connected to the subsequent power storage device.

[0017] The above disclosed power generation device realizes the reciprocating rotation of the gear shaft according to the swing of the energy storage flywheel of the driving part and transmits it to the speed-increasing part synchronously. The speed-increasing part increases the speed through the speed-increasing gear pair and drives the generator to rotate to realize power generation. Due to the reciprocating swing of the energy storage flywheel of the driving part, the generator generates alternating current, and the alternating current is regulated when it is transmitted to the subsequent electric shock device.

[0018] Furthermore, the structure of the drive box can be constructed in a variety of forms, which are not limited to a single one. Here, an optimization is made and one of the feasible options is proposed: the drive box includes a lower box body and an upper box body, and the lower box body and the upper box body cooperate to form a closed installation space; the energy storage flywheel and the gear shaft are both installed in the installation space. When such a solution is adopted, the installation space formed in the lower box body and the upper box body can prevent external moisture from entering, so the energy storage flywheel and the gear shaft are located in a closed space and will not be corroded. When the drive box body is placed on a marine vessel or other facility, it shakes with the waves to achieve the swing of the energy storage flywheel.

[0019] Furthermore, in the process of transmitting rotation, the stability of transmission can be improved by optimizing the structure, and collision, interference, etc. that occur during transmission can be reduced. This can be achieved through a variety of structures, which are not limited to the only one. Here, optimization is performed and one feasible option is proposed: the transmission input shaft and the gear shaft are synchronously connected through the first elastic coupling, and the transmission output shaft and the motor shaft are synchronously connected through the second elastic coupling. When such a solution is adopted, the first elastic coupling and the second elastic coupling can both be elastically released in the axial direction, circumferential direction and normal direction to protect the two butted shafts.

[0020] Furthermore, in the present invention, the structure of the speed increasing part is optimized, and a variety of solutions can be adopted, which are not limited to the only one. Here, one feasible option is proposed: the transmission input shaft, the speed increasing gear pair and the transmission output shaft form a planetary gear speed increaser. When such a solution is adopted, the rotation is transmitted to the planetary gear speed increaser through the gear shaft, and the speed is increased and then transmitted to the generator, thereby achieving efficient power generation.

[0021] Furthermore, the power generation device of the utility model also includes other structures, which are optimized here and one feasible option is proposed: it also includes a supporting platform, and the driving box is connected and arranged on the supporting platform.

[0022] Furthermore, other structures may also adopt more options: including a support frame, the support frame is arranged on the support platform, and the speed increasing part and the power generating part are arranged on the support frame.

[0023] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0024] The utility model improves the structure of the energy storage flywheel so that it can generate greater torque during swinging, thereby improving the efficiency of power generation; at the same time, the power generation device as a whole does not contact seawater, reducing the risk of damage by seawater erosion, and can effectively ensure the service life and reliability of the power generation device.

[0043] Example 2

[0044] The content of the above embodiment 1 describes the structure of the energy storage flywheel, and this embodiment provides a power generation device that generates electricity by utilizing the swing of the energy storage flywheel as a driving force, which will be described in detail below.

[0045] A wave energy power generation device, using the energy storage flywheel 3 described above, comprises:

[0046] The driving part is used to swing according to the shaking and transfer the kinetic energy to the speed increasing part 13; the driving part includes a closed driving box, in which an energy storage flywheel 3 is arranged, and the energy storage flywheel 3 cooperates with the gear shaft 9 and transfers the kinetic energy to the outside;

[0047] The speed increasing part 13 is used to transfer the kinetic energy of the driving part to the power generation part; the speed increasing part 13 includes a transmission input shaft 1301, a speed increasing gear pair and a transmission output shaft 1305, wherein the transmission input shaft 1301 is connected to the gear shaft 9, and the transmission output shaft 1305 is connected to the power generation part;

[0048] The power generation unit includes a generator 15, and the motor shaft of the generator 15 is driven by the transmission output shaft 1305, and the power output end of the generator 15 is connected to the subsequent power storage device.

[0049] The power generation device disclosed in this embodiment realizes the reciprocating rotation of the gear shaft 9 according to the swing of the energy storage flywheel 3 of the driving part and transmits it to the speed increasing part 13 synchronously. The speed increasing part 13 increases the speed through the speed increasing gear pair and drives the generator 15 to rotate to realize power generation. As the energy storage flywheel 3 of the driving part swings back and forth, the generator 15 generates alternating current, and the alternating current is regulated when it is transmitted to the subsequent electric shock device.

[0050] The structure of the drive box can be constructed in a variety of forms, which is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the drive box includes a lower box body 2 and an upper box body 10, and the lower box body 2 cooperates with the upper box body 10 to form a closed installation space; the energy storage flywheel 3 and the gear shaft 9 are both installed in the installation space. When such a solution is adopted, the installation space formed in the lower box body 2 and the upper box body 10 can prevent external moisture from entering, so the energy storage flywheel 3 and the gear shaft 9 are located in a closed space and will not be corroded. When the drive box is placed on a marine vessel or other facility, it shakes with the waves to achieve the swing of the energy storage flywheel 3.

[0051] Preferably, in this embodiment, the lower housing 2 is provided with a flywheel shaft 6 to cooperate with the energy storage flywheel 3, and both ends of the flywheel shaft 6 cooperate with the lower housing 2 through the first bearing 5; and the gear shaft 9 is matched to the upper housing 10, and both ends of the gear shaft 9 cooperate with the upper housing 10 through the second bearing 8. The left end cover 4 and the right end cover 11 are used to cover the two ends of the flywheel shaft 6 and the gear shaft 9 on the drive box.

[0052] Preferably, in this embodiment, a retaining spring 7 is provided on the flywheel shaft 6 for axially positioning the energy storage flywheel 3 .

[0053] In the process of transmitting rotation, the stability of transmission can be improved by optimizing the structure, and collision, interference, etc. in the transmission process can be reduced. This can be achieved through a variety of structures, which are not limited to the only one. This embodiment optimizes and adopts one of the feasible options: the transmission input shaft 1301 is synchronously connected with the gear shaft 9 through the first elastic coupling, and the transmission output shaft 1305 is synchronously connected with the motor shaft through the second elastic coupling 14. When such a solution is adopted, the first elastic coupling and the second elastic coupling 14 can be elastically released in the axial direction, circumferential direction and normal direction to protect the two butted shafts.

[0054] In this embodiment, the structure of the speed increasing part 13 is optimized, and multiple solutions can be adopted, which are not limited to the only one. This embodiment adopts one of the feasible options: the transmission input shaft 1301, the speed increasing gear pair and the transmission output shaft 1305 form a planetary gear speed increaser. When such a solution is adopted, the rotation is transmitted to the planetary gear speed increaser through the gear shaft 9, and the rotation speed is increased and then transmitted to the generator 15, thereby achieving efficient power generation.

[0055] Preferably, the planetary gear speed increaser comprises a planetary carrier connected to and rotating synchronously with a transmission input shaft 1301, a plurality of planetary gears 1304 arranged on the planetary carrier, a sun gear 1303 meshing with the planetary gears 1304, and the sun gear 1303 is also synchronously transmitted with a transmission output shaft 1305; and also comprises an outer shell 1302, in which an inner gear ring structure meshing with the planetary gears 1304 is arranged.

[0056] The power generation device of this embodiment also includes other structures, which are optimized here and one of the feasible options is adopted: it also includes a supporting platform 1, and the driving box is connected and arranged on the supporting platform 1.

[0057] In this embodiment, other structures of the power generation device can also adopt more options: it also includes a support frame 16, the support frame 16 is arranged on the support platform 1, and the speed increasing part 13 and the power generation part are arranged on the support frame 16.

[0058] Here is an example of using the above scheme.

[0059] An energy storage flywheel and a wave energy power generation device, such as Figure 1 to Figure 6 As shown, in order from left to right and from bottom to top, it includes a support platform 1, a lower box 2, an energy storage flywheel 3, a left end cover 4, a first bearing 5, a flywheel shaft 6, a retaining spring 7, a second bearing 8, a gear shaft 9, an upper box 10, a right end cover 11, a first elastic coupling 12, a planetary gear speed increaser 13, a second elastic coupling 14, a permanent magnet synchronous generator 15, and a support frame 16.

[0060] The support platform 1 is installed inside the working device to ensure isolation from the seawater, and serves as an installation support platform for the entire wave energy utilization power generation device. The entire power generation device is a structural module, which is easy to disassemble and maintain. It is installed sequentially from left to right, and the lower box 2 is installed on the upper plane of the left end.

[0061] The lower box 2, as Figure 3 and Figure 4 As shown, it is installed in cooperation with the upper box body 10, the left end cover 4, and the right end cover 11 to form a closed box body, in which the entire energy acquisition module part is installed, mainly supporting the weight of the energy acquisition part, specifically including the energy storage flywheel 3, the first bearing 5, the flywheel shaft 6, the retaining spring 7, the second bearing 8, and the gear shaft 9.

[0062] The energy storage flywheel 3, such as Figure 1 , Figure 2As shown, it is composed of a pendulum 301, a connecting plate 302, a swing arm 303 and a sector gear 304. The pendulum 301 of the lower part of the energy storage flywheel 3 is designed as a semi-cylindrical solid structure, and the material is preferably steel or cast iron, in order to ensure that the energy storage flywheel 3 has a larger inertia and the center of gravity is as low as possible during operation; the connecting plate 302 is connected to the swing arm 303 and the pendulum 301 by four evenly distributed bolts; the upper side of the swing arm 303 is designed to be semicircular and a keyway hole is opened at the center of the circle, and the semicircular part is welded to the concave semicircular hole of the sector gear 304; the tooth profile of the sector gear 304 is designed according to the tooth profile of a standard cylindrical spur tooth.

[0063] The keyway hole of the flywheel swing arm 303 is fixedly connected to the flywheel shaft 6 via a flat key. In order to prevent the flywheel from moving axially along the flywheel shaft 6 during the swinging operation, a clamping groove is provided on both sides of the part where the flywheel swing arm 303 is fixed to the flywheel shaft 6. The clamping groove is connected to the retaining spring 7. Due to the limiting effect of the retaining spring 7, it is ensured that the energy storage flywheel 3 does not move axially when it swings; a first bearing 5 is fitted on each of the end faces of the shaft at both ends of the flywheel shaft 6.

[0064] The first bearing 5 is preferably a deep groove ball bearing, which has an interference fit with the end of the flywheel shaft 6. The first bearings 5 ​​on both sides are respectively placed on the semicircular arc ends of the lower box body 2, so as to ensure that the entire flywheel is suspended on the lower box body 2 and can swing freely.

[0065] The tooth profile of the sector gear 304 meshes with the middle gear of the gear shaft 9, and the transmission ratio of the number of teeth of the sector gear 304 to the number of teeth of the gear shaft is i. A second bearing 8 is also provided at each of the two ends, and the second bearing 8 is placed on both sides of the semicircular arc surface of the upper box body 10. In this way, when the energy storage flywheel 3 swings, it drives the gear of the gear shaft 9 to rotate and achieves a first-stage speed increase.

[0066] The energy storage flywheel 3 obtains kinetic energy from the ocean by shaking, and on the other hand, the fan-shaped gear 304 meshes with the gear on the gear shaft 9 to achieve a first-stage speed increase. Figure 1 , Figure 2 As shown, the motion relationship is explained. Assuming that the energy storage flywheel 3 swings in the clockwise direction, the swing center is O, and the center of gravity is G, then the distance between the flywheel rotation radius OG is R1, the rotation angular velocity is w1, the tangential centrifugal force is F1, and the rotation radius of the meshing point between the fan gear on the upper side of the flywheel and the gear shaft is R2, where R1>R2, the tangential driving force of the flywheel on the gear shaft is F2, the resistance of the gear shaft to the flywheel is F2', and the angular velocity of the gear shaft is w2.

[0067] According to Newton's third law of action and reaction: F2'=F2

[0068] According to the principle of force arm: F1×R1=F2×R2 R1>R2 then: F2'=F2>F1

[0069] According to the gear transmission relationship: w2 = i·w1

[0070] From the above, it can be seen that by designing the flywheel to increase the rotation radius R1 as much as possible, it is not only possible to overcome the resistance and provide a larger driving force F2, but also to achieve a speed-increasing effect.

[0071] The right shaft end of the gear shaft 9 is connected to the input shaft of the planetary gear speed increaser 13 through a first elastic coupling 12 .

[0072] The first elastic coupling 12 includes connecting parts such as a transmission shaft, an adjusting nut, an upper support seat, a spring, a steel ball, and a lower support seat.

[0073] The planetary gear speed increaser 13 is a two-stage gear speed increaser mechanism. Figure 3 to Figure 6 As shown, the specific components include an input shaft 1301, a speed increaser housing 1302, a sun gear 1303, a planetary gear 1304, and an output shaft 1305. The output shaft of the planetary gear speed increaser 13 is connected to the input shaft of the generator 15 through the second elastic coupling 14.

[0074] The working principle of the second elastic coupling 14 is the same as that of the first elastic coupling 12, but the model is different.

[0075] The generator is a permanent magnet synchronous generator, which has a gear speed increasing mechanism fixedly installed on it and is a low-power generator.

[0076] The generator 15 and the planetary gear speed increaser 13 are respectively connected to a support frame 16 for fixing, and the support frame 16 is unloaded and fixed on the support platform 1 .

[0077] The working principle of the whole device is as follows: the system is placed inside a movable working device in the ocean. Due to the effect of external shaking, the dynamic balance of the flywheel inside the casing is destroyed, resulting in a certain angle of deflection, thereby obtaining kinetic energy. The speed is then increased through the flywheel's own first-stage speed increase and the planetary gear speed increaser's second-stage speed increase. A safety elastic coupling is connected in the middle, and the speed is increased again through the speed increase mechanism on the permanent magnet synchronous generator. The rotation drives the generator shaft to rotate, cutting the magnetic flux lines to generate electricity, and then a stable current is obtained through the electric energy post-processing system to charge the battery module, obtain electric energy, and store it to continuously provide power for the subsequent working device.

[0078] The present invention provides a swingable and movable small charging system, which has the following advantages:

[0079] (1) The device has a simple structure and is smaller in size than a general power generation device. All components can be installed inside the aircraft as an independent component. This can isolate the power generation device from the external marine environment and protect it from seawater corrosion, dynamic sealing, marine biological adhesion, etc. This will greatly reduce its cost, which is an advantage of the present invention.

[0080] (2) The device has a wide range of uses, not only for military but also for civilian use. For example, submarines, surface ships, fishing boats, etc. can all be equipped with the device, which will generate vibrations under the action of wave energy and can be used to generate electricity. It can provide power and lighting for various ships and fishing boats.

[0081] (3) The design of the flywheel is ingenious and compact, and is divided into a pendulum, a swing arm, and a sector gear. Connected by bolts, it can not only increase the speed of the gearbox, but also provide a strong driving force. It is very convenient to install, disassemble, unload energy, and maintain.

[0082] (4) The present invention also eliminates the hydraulic and pneumatic components of other wave energy power generation devices, thereby simplifying the structure and reducing the cost, thereby being a cheap and practical wave energy power generation device.

[0083] (5) The present invention has a simple structure, is easy to process, and is relatively simple to install and maintain.

[0084] The above are the implementation methods listed in this embodiment, but this embodiment is not limited to the above optional implementation methods. Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can obtain other various implementation methods under the inspiration of this embodiment. The above specific implementation methods should not be understood as limiting the protection scope of this embodiment.
