Description

Technical Field

[0001] The invention relates to the technical field of electrical machinery, and in particular to a wave energy power generation device. Background Art

[0002] As global land resources are becoming increasingly depleted, the exploration and development of renewable energy has become particularly important. As the largest resource treasure house on Earth, the ocean contains huge and diverse energy, including wave energy, tidal energy, current energy, temperature difference energy, salinity difference energy, etc. Among them, wave energy, as a high-quality ocean energy, has attracted widespread attention due to its wide distribution, large reserves, high energy density, and simple energy conversion device.

[0003] There are many types of wave energy power generation devices, which can be classified into shore-based and floating types according to the installation location. According to the intermediate energy conversion form, they can be divided into mechanical, direct-drive, friction and piezoelectric types. The mechanical type mainly uses gear transmission or hydraulic system to drive the generator to rotate and generate electricity. The direct-drive structure is similar to a linear motor, which directly converts the linear motion of the float into electrical energy. The friction type converts the float motion into reciprocating motion through a mechanical structure and generates electricity through friction. The piezoelectric type mostly generates electricity by repeatedly squeezing the piezoelectric material through internal vibration. According to the energy capture method, it is mainly divided into oscillating float type, oscillating water column type, raft type, nodding duck type, pendulum type and wave-riding type.

[0004] The raft wave energy power generation device absorbs the energy generated by the relative rotation between the two raft bodies through a hydraulic device. The two raft bodies rise and fall with the waves and continuously absorb energy. The pendulum wave energy power generation device is expensive and has poor damage resistance.

[0005] The oscillating water column type wave energy power generation device, under the ups and downs of waves, the gas in the internal chamber enters and exits from the small opening on the top to drive the turbine to rotate. Generally speaking, there are two types of Wells turbines and impulse turbines. Wells turbines use symmetrical airfoil blades, and the turbines turn in the same direction when the air enters and exits. The impulse turbine uses guide vanes to ensure that the turbines turn in the same direction when the air enters and exits. Due to the large loss of air pushing the turbine, the efficiency of the oscillating water column type is not high.

[0006] The pendulum wave energy power generation device has a similar structure to the raft type, but the difference is that the raft type floats on the sea surface, and the two raft bodies are not fixed, and there is relative motion between them. The pendulum type has one end fixed, and only one float swings back and forth. Its disadvantage is that most of the mechanism is underwater, and the anti-corrosion requirements are higher.

[0007] Researchers have conducted extensive research on wave energy conversion devices from the perspectives of theory, simulation, and experiment, and have proposed a variety of new structures and methods. From the initial mechanical drive generator to the new power generation methods such as piezoelectricity, electromagnetics, and nano-friction that have emerged in recent years, wave energy conversion devices have developed rapidly. Researchers have adopted horizontal and vertical pendulums as the primary energy capture system for the design of micro wave energy power generation buoys. The design innovatively integrates new technologies such as piezoelectricity and electromagnetics, replacing the traditional design of secondary transmission to the generator, reducing the loss during energy transfer. Although the development of wave energy power generation devices is thriving, there are also some problems in the research of wave energy conversion devices:

[0008] New power generation methods such as piezoelectricity, electromagnetics, and nanofriction are mostly only in the experimental research stage and are still some distance away from practical application. The long-term reliability of these technologies needs to be confirmed, and the cost is high. The progress of wave energy-powered buoys is slow, and there is even less research on wave energy conversion devices that power submerged buoys. Summary of the invention

[0051] like Figure 1-6 As shown, a wave energy power generation device includes: a plurality of up and down moving mechanisms 1, wherein the up and down moving mechanisms 1 are configured to move up and down along a spiral rod 5 under the action of waves; the up and down moving mechanisms 1 are responsible for capturing the up and down movement of waves and converting them into rotational kinetic energy.

[0052] The driving gear assembly 11 includes a sealed bearing 111, a driving gear 112, and a rotating wheel 113. The sealed bearing 111 ensures that water does not enter the device. The driving gear 112 is fixed to the rotating wheel 113. The rotating wheel 113 cooperates with the spiral rod 5 through the ball head 1131 on the inner wall. When the waves drive the spiral rod 5 to move up and down, the rotating wheel 113 rotates accordingly, thereby driving the driving gear 112 to rotate.

[0053] The transmission gear assembly 12 includes a transmission gear 121 (a first transmission gear 1212 and a second transmission gear 1212), a clockwise one-way gear 122, a counterclockwise one-way gear 123, an output gear 124 and a reversing gear 125. These gears work together to ensure that the output gear 124 always rotates in the same direction regardless of how the waves fluctuate up and down. The clockwise one-way gear 122 and the counterclockwise one-way gear 123 achieve this function through the reversing gear 125.

[0054] The scroll spring box gear 131 is coaxial with the output gear 124, receives and stores the rotational kinetic energy transmitted by the output gear 124, and converts it into elastic potential energy of the scroll spring.

[0055] The escapement mechanism 14 includes an escape wheel 141, an escape fork 142, a balance wheel and a hairspring 143. It stabilizes the rotation speed of the gear transmission system, prevents the energy in the spiral spring from being suddenly released, and ensures the smooth progress of the power generation process. The escape wheel 141 interacts with the escape fork 142, and the rhythm of rotation is controlled by adjusting the balance wheel and the hairspring 143.

[0056] The mass block 2 is arranged at the bottom of the power generation device to maintain the stability of the device in the water; it increases the stability of the device in the water, prevents excessive shaking caused by the action of waves, and ensures the stability and efficiency of the power generation process. The mass block 2 is arranged at the bottom of the central axis of the buoyancy barrel 3 to maintain the stability of the device in the water and further prevent excessive shaking.

[0057] The buoyancy barrel 3 is arranged in the middle of the power generation device. In this embodiment, the four up-and-down moving mechanisms 1 are arranged on the four edges of the rectangular parallelepiped frame. The buoyancy barrel 3 is in the middle to maintain the balance of the up-and-down moving mechanism 1 and to capture the kinetic energy of the waves.

[0058] The guide rail 4 is arranged on one side of the up-down moving mechanism 1 to limit the movement direction of the up-down moving mechanism 1 and prevent the up-down moving mechanism 1 from rotating as a whole, thereby rotating the internal driving gear 112. The guide rail 4 is arranged on one side of the up-down moving mechanism 1 to limit its movement direction, ensure that the up-down moving mechanism 1 can move along a predetermined path, and improve the energy conversion efficiency.

[0059] The screw rod 5 interacts with the up-and-down moving mechanism 1 to drive it to move up and down. The up-and-down moving mechanism 1 converts the up-and-down movement into rotational kinetic energy to drive the generator 153 to rotate.

[0060] The power generation device further includes a mounting plate 6, an upper mounting frame 61 and a lower mounting frame 62; the gear assembly is arranged between the mounting plate 6 and the upper mounting frame 61, the escapement mechanism 14, the up-and-down moving mechanism 1 and the power generation assembly 15 are arranged between the mounting plate 6 and the lower mounting frame 62, and a guide hole is arranged on the mounting plate 6, through which the guide rail 4 passes. As a supporting and fixing structure, it ensures that each component can be assembled together in a predetermined manner to form a complete power generation device.

[0061] The up-and-down moving mechanism 1 comprises a driving gear assembly 11, a transmission gear assembly 12, a scroll spring box gear 131, an escapement mechanism 14, and a power generation assembly 15; the transmission gear assembly is used to drive the output gear 124 to always rotate in the same direction when the up-and-down moving mechanism 1 moves up and down; the scroll spring box gear 131 is connected to the gear assembly in a transmission manner to store the rotational kinetic energy in the scroll spring; the escapement mechanism 14 is used to stabilize the rotation speed of the gear transmission system so that the energy in the scroll spring will not be released suddenly.

[0062] The power generation assembly 15 includes a third transmission gear 151, a gear speed increaser box 152 and a generator 153. The spiral spring box gear 131 is meshed with the third transmission gear 151. The third transmission gear 151 drives the gear speed increaser box 152 and the generator 153 to convert the rotational kinetic energy into effective kinetic energy for power generation.

[0063] The up-and-down moving mechanism 1 is encapsulated in a corrosion-resistant shell 16 to prevent seawater erosion and ensure long-term operation of the device. The side of the corrosion-resistant shell 16 is arc-shaped, and the two end faces are conical. The side is arc-shaped and the two end faces are conical. This design is conducive to reducing water flow resistance and improving the efficiency of the device.

[0064] The driving gear assembly 11 includes a sealed bearing 111, a driving gear 112, and a rotating wheel 113; the sealed bearing 111 is installed between the corrosion-resistant housing 16 and the rotating wheel 113 to prevent water from entering the device; the driving gear 112 and the rotating wheel 113 are fixed together, and the inner wall of the rotating wheel 113 is provided with a ball head 1131 that cooperates with the spiral rod 5 to realize the conversion of up and down motion into rotational motion.

[0065] The transmission gear assembly 12 includes a transmission gear 121, a clockwise one-way gear 122, a counterclockwise one-way gear 123, an output gear 124 and a reversing gear 125. The transmission gear 121 includes a first transmission gear 1211 and a second transmission gear 1212. The driving gear 112 is meshed with the first transmission gear 1211 and the second transmission gear 1212 at the same time. The clockwise one-way gear 122 is coaxial with the first transmission gear 1211, and the counterclockwise one-way gear 123 is coaxial with the second transmission gear 1212. The clockwise one-way gear 122 is meshed with the output gear 124, and the counterclockwise one-way gear 123 is meshed with the output gear 124 through the reversing gear 125.

[0066] The clockwise one-way gear 122 and the counterclockwise one-way gear 123 are key components designed to ensure that the output gear 124 always rotates in the same direction. This design is crucial for wave energy power generation devices because the ups and downs of waves will cause changes in the direction of rotation. Without this one-way mechanism, the generator 153 will not be able to continuously and effectively generate electricity.

[0067] The clockwise one-way gear 122 allows power transmission only when it rotates in the clockwise direction. When the wave pushes the screw rod 5 upward, the up-and-down moving mechanism 1 moves upward, causing the driving gear 112 to rotate, and transmitting power to the clockwise one-way gear 122 through the first transmission gear 1211. At this time, the clockwise one-way gear 122 meshes with the output gear 124 and drives it to rotate clockwise.

[0068] The counterclockwise one-way gear 123 allows power transmission only when it rotates counterclockwise. When the waves drop, the screw rod 5 moves downward, and the up-and-down moving mechanism 1 moves downward accordingly, and the driving gear 112 rotates in the opposite direction (i.e., counterclockwise). At this time, the driving gear 112 drives the counterclockwise one-way gear 123 to rotate through the second transmission gear 1212, and the counterclockwise one-way gear 123 transmits power to the output gear 124 through the reversing gear 125, so that the output gear 124 continues to rotate clockwise.

[0069] The function of the reversing gear 125 is to change the direction of power transmission so that the output gear 124 can keep rotating in one direction regardless of how the driving gear 112 rotates (clockwise or counterclockwise). The counterclockwise one-way gear 123 is connected to the output gear 124 through the reversing gear 125, so that even if the driving gear 112 rotates counterclockwise, the output gear 124 can still rotate clockwise.

[0070] In actual design, one-way gears usually use a ratchet and pawl mechanism to achieve one-way rotation. When the one-way gear needs to transmit power in a specified direction, the pawl will grab the teeth on the ratchet to prevent it from reversing. When power does not need to be transmitted, the pawl will disengage the ratchet under the action of the spring, allowing the ratchet to rotate freely without transmitting any torque.

[0071] In the wave energy power generation device, such a one-way mechanism ensures that the output gear 124 always rotates in a direction that is conducive to power generation. In this way, regardless of whether the waves cause the screw rod 5 to move up and down, the rotation ultimately output to the generator 153 is continuous and consistent, thereby improving power generation efficiency and system reliability.

[0072] The scroll spring box gear 131 is coaxial with the output gear 124, and the output gear 124 transmits the rotational kinetic energy to the scroll spring box 13. The escapement mechanism 14 includes an escapement wheel 141, an escapement fork 142, a balance wheel and a hairspring 143; the escapement wheel 141 is connected to the third transmission gear 151 through its axis, and the teeth of the escapement wheel 141 interact with the fork of the escapement fork 142; the escapement fork 142 is installed on the escapement mechanism 14 frame through its fork shaft, and drives the balance wheel to swing; the balance wheel is connected to the escapement mechanism 14 frame through the hairspring 143, and the hairspring 143 controls the reciprocating motion of the balance wheel.

[0073] The scroll spring box 13 and the escapement mechanism 14 play an important role in the wave energy power generation device. They are responsible for storing energy and controlling the energy release speed respectively, ensuring a smooth and orderly power generation process.

[0074] The spiral spring box 13 is an energy storage device, comprising one or more tightly wound springs, which can compress or twist when subjected to force, storing mechanical energy. When the force is removed, the spring will return to its original state, releasing the previously stored energy.

[0075] In the wave energy power generation device, the scroll spring box gear 131 is coaxially mounted with the output gear 124. When the output gear 124 rotates due to the wave energy, it causes the spring in the scroll spring box 13 to twist and store energy through the gear meshing action. Once the wave energy is temporarily weakened or disappears, the spring will begin to release the previously stored energy and continue to drive the gear to rotate, thereby ensuring a continuous supply of energy.

[0076] The escapement mechanism 14 includes an escapement wheel 141, an escapement fork 142, a balance wheel and a hairspring 143. The escapement wheel 141 is connected to the third transmission gear 151 through its axis, and the teeth of the escapement wheel 141 interact with the fork shoe of the escapement fork 142. The escapement fork 142 is installed on the escapement mechanism 14 frame through its fork shaft and drives the balance wheel to swing. The balance wheel is connected to the escapement mechanism 14 frame through the hairspring 143, and the hairspring 143 controls the reciprocating motion of the balance wheel.

[0077] When the escape wheel 141 rotates, it interacts with the pallet fork 142, causing the pallet fork 142 to swing back and forth. The swing of the pallet fork 142 controls the swing frequency of the balance wheel through the connection with the balance wheel. The swing frequency of the balance wheel determines the speed of energy release, thereby controlling the rotation speed of the generator 153.

[0078] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
