Description

[0001] Technical Field: The technical solution of this device belongs to the field of new energy power.

[0002] Technical Background: The ocean covers approximately 71% of the Earth's surface, possessing enormous energy development potential. Ocean waves, derivatives of wind and the sea, possess potential energy and instantaneous buoyancy, and are also renewable and sustainable, making them a feasible power source for generator sets. With societal progress and the widespread adoption of digitalization and intelligentization, the demand for electricity is constantly increasing. Meanwhile, environmental factors such as ecology and climate are continuously compelling people to move towards green and low-carbon development. Therefore, clean and inexpensive green energy is an urgent societal need.

[0003] Invention Content: A wave power generation device aims to collect the potential energy and instantaneous buoyancy of ocean waves and convert this energy into clean electrical energy. The device can be simply divided into three main parts: the main body, the working float, and the vortex energy storage device. The main body consists of a wave-blocking plate, a main float, and the main body itself. The wave-blocking plate reduces the impact of large waves on the sides of the working float. The main float, located at the center point of the entire device, serves as the central fulcrum. Due to the weight of the main body, when a wave comes, half of the device is lifted by the working float, causing the center of gravity to tilt towards the other half. The working float below the main body, under the pressure of the main body, can also transfer kinetic energy to the vortex energy storage device. The interior of the main body is a hollow steel structure, which can serve as a compressed air storage chamber for energy storage. Besides collecting kinetic energy, the working float also provides auxiliary support for the main body. The spring at the guide rod is an important supporting component. With the cooperation of the spring and the vortex energy storage device, the working float has a good shock absorption effect, reducing the swaying frequency of the device and increasing its durability. The working float has a hollow steel structure inside, which can be used as a compressed air storage chamber for energy storage. The function of the vortex energy storage device is to use ratchet wheels at both ends of the central shaft to lock the power transmitted from the working float into the vortex spring, so that it can only be output from the gear ring at the output end, and stably delivered to the generator set. When the input is greater than the output, the excess power will be stored to support the arrival of the next wave or the wave after that. Due to the advantages of fast energy storage, fast energy release, stability and high energy conversion efficiency, the vortex energy storage device is used as the first-stage energy storage part, while the main body, the working float and the internal air storage chamber serve as the second-stage backup energy storage part. Six working floats are evenly distributed around the main body, serving as auxiliary fulcrums. When waves pass over the working floats, they are forced to move upwards through components such as ball joints, guide rods, and chains, transmitting power to the vortex energy storage device. The vortex energy storage device then stably delivers power to the generator set. When there is excess power, an air compressor can be used to convert electrical energy into compressed air for storage. When there is a power shortage, the compressed air is converted back into electrical energy.

[0004] Known ocean-powered power generation devices include tidal power, offshore wind power, and offshore photovoltaic power. Tidal power has very high requirements for topography, terrain, and tide height, thus limiting its widespread adoption. Offshore wind power devices suffer from unpredictable wind speeds and severe weather; the large windward area of ​​the blades and the significant leverage forces exerted by the blades on the column and foundation (land-based or floating foundation) result in high costs, especially considering the need to withstand typhoons and other severe weather. Furthermore, the relatively large size of the components makes installation on the sea surface very difficult. Offshore photovoltaic power generation is highly dependent on meteorological conditions, geographical location, and day-night cycles, exhibiting poor stability. A wave power generation device offers the following advantages compared to the above three types of power generation devices:

[0005] 1. It has a wide range of applications and can operate effectively in waters where the waves are more than half a meter above the sea level. The water depth requirement is that the device does not touch the seabed during its swaying and shaking.

[0006] 2. The installation is easy. After the device is manufactured, it can be towed to the designated sea area and anchored with iron cables and cables.

[0007] 3. High stability, can operate 24 hours a day.

[0008] 4. High safety, strong resistance to extremely harsh weather, large contact area between the device and the water surface, not easy to capsize, and the working float has a shock absorption effect when collecting kinetic energy, which can greatly improve the stability of the device.

[0009] 5. Low cost, simple equipment setup, low construction cost, and low maintenance cost.

[0010] 6. It has a certain energy storage capacity and can store excess electricity in the form of compressed air.

[0012] Specific implementation method: Tow the manufactured device to an area with waves exceeding half a meter and the seabed being more than 5 meters below the bottom of the device (please refer to the attached diagram in the instruction manual for the following markings). Figure 1 The anchor cable (28) is used to fix the device to prevent displacement and rotation. When the wave lifts the working float (2), the working float does not move upward in parallel because the wave is moving. To ensure that the guide post (6) and guide tube (9) can slide smoothly when the working float moves upward in an inclined manner, the ball head (4) and ball head fixing module (3) play a major role. When the guide post (6) is pushed by the working float (2), the ball head (4) and the ball head fixing module (3), it drives the chain fastener (11), the chain (14) and the lower sprocket (12) to rotate, which is transmitted to the ratchet (21) at the B end of the central shaft of the vortex energy storage device. The ratchet (21) at end B of the central shaft is in the transmission state, while the ratchet (20) at end A of the central shaft is in the sliding state, transmitting power to the vortex energy storage device (22). The output gear ring (15) continuously outputs power to drive the generator (16) to generate electricity, which is then output from the output wire (18). When the waves pass the bottom of the working float, to prevent the potential energy stored in the vortex spring in the vortex energy storage device from rebounding from the central shaft, the ratchet (20) at end A of the central shaft is in the locked state, and the ratchet (21) at end B of the central shaft is in the sliding state. The chain (14), guide post (6), and working float (2) are in the return state under the action of the spring (5). The limit post (7) and the buffer pad (8) are to prevent the working float from being pushed up too much and damaging the limiting function of the spring. The main float (1) bears half the weight of the entire device, reducing the load-bearing force of the spring (5) and increasing the stability of the device. The wave deflector (25) prevents large waves from hitting the side of the working float and causing deformation of (6), and also prevents strong winds from shaking the device. The connecting air pipe (27) is an accessory that connects the interior of the main body (23) and the internal air storage chamber of the working float. The internal reinforcing frame (26) is used to strengthen the overall strength of the main body and the working float. The device compartment (24) houses components such as the vortex energy storage device and the generator. The ground anchor cable (28) is an important component to prevent the device from shifting or rotating. The bolt (13) is used to fix the chain connecting fastener (11) to the upper end of the guide post, and the buffer limit pad is fitted on the guide post. The generator mounting bracket (17) and the energy storage device mounting bracket (19) are both fixed to the upper platform of the main body (23).

[0013] Please refer to the following markings. Figure 5In the vortex energy storage device, the ratchet (2) at the B end of the central shaft is the power input end. When there is power input, the ratchet (2) at the B end of the central shaft is in the transmission state, and the ratchet (13) at the A end of the central shaft is in the sliding state. After the vortex spring (5) is elastically deformed, it drives the spring housing (7), the spring compartment cover (10), and the gear ring (8) to rotate outward. When the ratchet (2) at the B end of the central shaft does not input power, in order to prevent the power stored in the vortex spring from rebounding from the central shaft (16), the ratchet (13) at the A end of the central shaft is in the locked state (because the outer circle of the ratchet at the A end of the central shaft has a keyway fixed on the A end bracket (14)). Therefore, the output end of the vortex energy storage device only outputs, and the input end only inputs, without affecting each other. When the input is greater than the output, excess power will be stored.

[0014] The inner end of the spiral spring (5) is locked in the groove of the central shaft (16), and the outer end is equipped with a spiral spring through pin (15). A bearing (11) is mounted on the central shaft, and the spring housing (7) is fitted on the bearing (11). The sliding groove is aligned with the spiral spring through pin (15). The spring chamber cover (10) is fitted on the bearing (11) on the central shaft, and the sliding groove is aligned with the spiral spring through pin (15). It is connected to the spring housing (7) by bolts (9). The gear ring (8) is fitted on the outer circle of the spring chamber cover (10) with a tight clearance. The upper end of the B-end bracket (4) is equipped with a bracket bearing (6), through which the central shaft (16) passes. The B-end key (3) locks the B-end ratchet (2) of the central shaft and is locked by bolts (1). The ratchet (13) at the A end of the central shaft is fitted onto the key (12) at the A end of the central shaft, and the upper end of the bracket (14) at the A end is fitted onto the outer circle of the ratchet at the A end of the central shaft and is locked in the keyway of the outer circle of the ratchet.
