Description

Technical Field

[0001] This invention relates to the field of wave power generation technology, and more specifically to a multimodal wave power generation device. Background Technology

[0002] Wave energy is a specific form of ocean energy and one of the most important energy sources in the ocean. Its development and utilization are crucial for alleviating the energy crisis and reducing environmental pollution. Traditional wave power generation uses mechanical transmission mechanisms to transfer wave energy from reciprocating motion to unidirectional rotational motion to drive a generator. These mechanical transmission mechanisms are prone to vibration, and the intermediate conversion stage reduces energy conversion efficiency. Linear generators, which can directly convert reciprocating linear motion into electrical energy, offer a promising and innovative solution for wave power generation, boasting advantages such as simple structure, high reliability, and high efficiency. However, due to the low wave speed, capturing wave energy through vibration requires a large counterweight, and the generator's power is fixed, making it insufficient for capturing large waves. Using multiple linear generators to address this issue results in bulky generators with low power density and high manufacturing costs, limiting the further development of permanent magnet linear motors in wave power generation. Therefore, a multi-mode wave power generation device is proposed to solve these problems. Summary of the Invention

The upper connecting plate is connected to the oscillator, and the lower connecting plate is connected to the housing. Each of the main telescopic rods is equipped with:

[0031] When the limit ball rotates to the locking groove, it squeezes one end of the lever and controls the extension of the lever to swing away from the surface of the main telescopic rod, causing the anti-slip layer to detach from the surface of the main telescopic rod.

[0032] Beneficial effects: (1) This invention uses the cooperation of a linear power generation mechanism and an oscillator, and suspends the oscillator below the straight axis of the linear power generation mechanism's mover.

[0033] (2) The present invention provides two flywheel mechanisms in the oscillator body, and the two flywheel mechanisms are symmetrically installed on the upper and lower sides of the energy conversion mechanism. During the operation, the two flywheel mechanisms rotate synchronously and in opposite directions, which can offset the overall anti-torque. This makes the whole device have no net angular momentum and will not deflect due to the rotation of a single flywheel mechanism, making the device more resistant to external disturbances and improving the overall stability of the device.

[0034] (3) In this invention, the magnetic coupling transmission structure enables a “soft connection” between the flywheel mechanism and the output end, which plays a role in rapid low-speed start-up response. In addition, based on the magnetic coupling transmission structure, this invention sets up a dynamic connector, which can mechanically connect the output end and the input shaft when the input shaft speed reaches the preset speed. This setting enables rapid low-speed start-up response through the magnetic coupling transmission structure in the initial stage. Then, as the rotation reaches a certain speed, the dynamic connector intervenes to compensate for the slip and efficiency loss of the magnetic coupling transmission structure.

The entire elastic suspension mechanism can be disassembled independently from the housing so as to replace different types of elastic suspension mechanisms as needed. In addition, based on the elastic suspension mechanism, the present invention can connect and disconnect individual support springs in the elastic suspension mechanism through the action of auxiliary telescopic rods, support springs and locking parts, so as to more flexibly select the appropriate number of support springs to participate in the work according to the needs, so as to meet different needs.

[0047] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or several specific embodiments of the multimodal wave power generation device of this invention, and does not strictly limit the scope of protection specifically claimed by this invention.

[0048] A multimodal wave power generation device includes a housing 1 and an oscillator located within the housing. The oscillator is configured to move relative to the housing 1 in the vertical direction as it undulates with the waves. The oscillator includes an energy conversion mechanism for converting the relative linear movement of the oscillator with the housing 1 into rotational motion at an output end 45, and a flywheel mechanism for storing the rotational kinetic energy generated at the output end 45 of the energy conversion mechanism. A linear power generation mechanism is also installed on the top of the housing. (Reference) Figure 1 As shown, the stator of the linear power generation mechanism 7 is mounted on the housing 1. The direct shaft 71 of the mover of the linear power generation mechanism 7 is connected to the oscillator. As the oscillator moves, the mover moves linearly within the stator through the direct shaft 71 to generate electricity. In this mode, the oscillator, which integrates flywheel energy storage and a rotary motor, is used as a counterweight, which increases the number of generators and the energy storage structure without affecting the overall mass and size. At the same time, it can be compatible with different wave conditions and improve energy conversion efficiency.

[0049] like Figure 1 As shown, multiple guide posts 2 are arranged vertically inside the housing 1. The oscillator includes a frame 31, which serves as a carrier for installing various devices and structures, including energy conversion mechanisms and flywheel mechanisms 6. The frame 31 is sleeved on the guide posts 2 to control the stable up-and-down movement of the oscillator.

[0050] The energy conversion mechanism is used to convert the relative linear movement between the oscillator and the housing 1 into the rotational motion of the output end 45. The energy conversion mechanism includes two output ends 45, which are coaxial and opposite in direction of movement of the oscillator. The energy conversion mechanism is configured to control the two output ends 45 to rotate synchronously and in opposite directions.

[0051] In one embodiment, reference Figure 2As shown, an energy conversion mechanism is provided, including a kinetic energy input gear 41, a kinetic energy input shaft 42, a kinetic energy input bevel gear 43, a kinetic energy output bevel gear 44, and an output end 45. A rack 5 is arranged vertically on the housing 1. The kinetic energy input gear 41 meshes with the rack 5. As the oscillator moves relatively linearly with the housing 1, the kinetic energy input gear 41 rotates, synchronously driving the kinetic energy input shaft 42 and the kinetic energy input bevel gear 43 to rotate. Kinetic energy output bevel gears 44 are meshed on both the upper and lower sides of the kinetic energy input bevel gear 43. The kinetic energy output bevel gears 44 are coaxially connected to the output end 45. The rotation of the kinetic energy input bevel gear 43 can synchronously drive the two upper and lower kinetic energy output bevel gears 44 to rotate synchronously and in opposite directions, thereby driving the corresponding two output ends 45 to rotate synchronously and in opposite directions.

[0052] To improve energy conversion efficiency, two sets of energy conversion mechanisms are installed, such as... Figure 2 The arrangement is symmetrical, and each energy conversion mechanism is equipped with a structure that converts linear reciprocating motion into unidirectional rotary motion. This structure can be an existing structure that can achieve this function, and will not be described in detail here.

[0053] refer to Figure 2 As shown, two flywheel mechanisms 6 are installed within the oscillator body, and the two flywheel mechanisms 6 are symmetrically mounted horizontally on the upper and lower sides of the energy conversion mechanism along the direction of movement of the oscillator body. The two flywheel mechanisms 6 are respectively connected to the corresponding output terminals 45 to store the rotational kinetic energy output by the output terminals 45. During operation, the synchronous and opposite rotation of the output terminals 45 drives the two flywheel mechanisms to rotate synchronously and oppositely, thus counteracting the overall anti-torque. The entire device has no net angular momentum and will not deflect due to the rotation of a single flywheel mechanism, making the device more resistant to external disturbances and improving the overall stability of the device.

[0054] In one embodiment, reference Figure 2 As shown, each flywheel mechanism 6 is provided with an input shaft 61, which is coaxially arranged with the output end 45. The input shaft 61 and the output end 45 are connected by a magnetic coupling transmission structure 8. The magnetic coupling transmission structure 8 enables a "soft connection" between the flywheel mechanism and the output end 45, which plays a role in rapid low-speed start-up response.

[0055] In one embodiment, based on the magnetic coupling transmission structure 8, a dynamic connector is further provided between the output end 45 and the input shaft 61. The dynamic connector is configured to mechanically connect the output end 45 and the input shaft 61 (i.e., "hard connection") when the input shaft 61 reaches a preset speed. This configuration enables a rapid low-speed start-up response through the magnetic coupling transmission structure 8 in the initial stage, driving the input shaft 61 to rotate. Then, as the rotation reaches a certain speed, the dynamic connector intervenes to mechanically connect the output end 45 and the input shaft 61, compensating for the slippage and efficiency loss of the magnetic coupling transmission structure 8.

[0056] In one specific embodiment, reference is made to Figures 3-7 As shown, a dynamic connector is illustrated to achieve the above functions. The dynamic connector includes a connecting plate 91, an inner plate 92, and a connecting shaft 93. The connecting plate 91 is coaxially mounted on the input shaft 61, and a cavity 911 is provided inside the connecting plate 91. Multiple teeth 912 are arranged axially on the inner wall of the cavity 911. The connecting plate 91 rotates synchronously with the input shaft 61. The inner plate 92 is installed inside the cavity 911 and can rotate freely relative to the cavity 911. It is coaxially arranged with the connecting plate 91. Several channels 921 are arranged radially inside the inner plate 92. A connecting rod 922 is installed in each channel 921. A spring 923 is connected to one end of the connecting rod 922 facing the inner plate 92. The connecting rod 922 is configured to stretch or compress the spring 923 radially under a certain centrifugal force, and engage with the teeth 912 of the cavity 911 after extending a certain distance out of the channel 921. The connecting shaft 93 connects the inner plate 92 and the output end 45.

[0057] refer to Figure 3 As shown, a connecting disk 91 and an inner disk 92 are coaxially mounted with a part of the magnetic coupling transmission structure 8, as well as multiple connecting rods 922 and springs 923 disposed in the cavity 911 of the inner disk 92.

[0058] refer to Figure 5 As shown, a connecting disk 91 is coaxially mounted with a part of the magnetic coupling transmission structure 8, and a ring of teeth 912 is provided circumferentially inside the connecting disk 91.

[0059] refer to Figure 6 As shown, the inner disk 92 is connected to the connecting shaft 93, and the inner disk 92 rotates synchronously with the connecting shaft 93.

[0060] During operation: In the initial state, spring 923 controls connecting rod 922 to be within channel 921. As output end 45 rotates, connecting shaft 93 drives inner disk 92 to rotate. At this time, the rotation speed is small, and the centrifugal force generated by the rotation is less than the force of spring 923. The position of connecting rod 922 remains unchanged. As the rotation speed increases, after a certain speed, the centrifugal force is greater than the force of spring 923. At this time, connecting rod 922 overcomes the force of spring 923 and moves radially, extending a certain distance out of channel 921 and engaging with teeth 912 of cavity 911. The extended end of connecting rod 922 can be set into a conical structure to facilitate engagement with teeth 912. When connecting rod 922 engages with teeth 912, a mechanical connection is formed between inner disk 92 and connecting disk 91, transmitting the kinetic energy output from output end 45 to input shaft 61. Figure 4 As shown, a pair of radially arranged guide plates 924 can be provided in the cavity 911 to restrict the connecting rod 922 between the two guide plates 924, guiding the connecting rod 922 to move only radially; at the same time, it can also transmit rotational force between the connecting plate 91, the connecting rod 922 and the inner plate 92.

[0061] In one embodiment, the connecting rod 922 is a hollow structure 926, which is equipped with a sliding counterweight 927. The counterweight 927 can slide freely within the hollow structure 926 along the direction of the channel 921. Under the action of centrifugal force, the slider can slide to the far end of the connecting rod 922, that is, the end away from the spring 923, so that after reaching a certain speed, the connecting rod 922 can be better guided to undergo radial displacement under the action of centrifugal force.

[0062] In one embodiment, a drive adjuster is installed at the center of the inner disk 92. Each spring 923 is encapsulated by a spring seat 925 and then slidably installed in the inner disk 92. The drive adjuster is configured to control the spring seat 925 and the spring 923 to move radially and adjust the initial position of the connecting rod 922. By setting different initial positions, the following can be achieved: (1) Working with the spring 923, under different initial positions, the connecting rod 922 needs to generate different moving distances to achieve the mechanical connection function. Therefore, different trigger speeds are required to achieve the same control of the initial position to dynamically adjust the preset connection speed; (2) The function of closing the dynamic connector can be achieved: that is, controlling the spring seat 925 to move to the maximum distance. This distance refers to the time when the deformation of the spring 923 reaches the maximum, the far end of the connecting rod 922 is not engaged with the tooth 912. At this time, even if the speed reaches the maximum, the connecting rod 922 cannot engage with the tooth 912, and always maintains only the magnetic coupling transmission structure 8 working, so as to achieve the switching of connection mode as needed.

[0063] refer to Figures 6-7As shown, the drive regulator includes a rotating block 101 and a connecting shaft 102. The rotating block 101 is coaxially mounted at the center of the inner disk 92, and a drive motor 103 is mounted on the rotating block 101 to control the rotation of the rotating block 101. An arc-shaped block 104 is provided at each spring seat 925 on the rotating block 101, and an arc-shaped groove 105 is formed on the outer side of the arc-shaped block 104. One end of the connecting shaft 102 is connected to the spring seat 925, and the other end is confined within the arc-shaped groove 105. The arc-shaped channel 105 is a sliding guide structure, for example, with a T-shaped cross-section. The connecting shaft 102 extends into one end of the arc-shaped channel 105 and is configured accordingly. This structure can restrict the connecting shaft 102 to slide within the arc-shaped channel 105. By rotating the rotating block 101, the arc-shaped channel 105 contacts the connecting shaft 102 at different positions, applying tension or thrust to the connecting shaft 102. Thus, the connecting shaft 102 pulls or pushes the spring seat 925 to slide radially, adjusting the initial position of the spring seat 925.

[0064] In one embodiment, reference Figure 1 As shown, an elastic suspension mechanism is also installed inside the housing 1. The elastic suspension mechanism is located on the movement path of the oscillator, and one end of the oscillator is connected to the oscillator. The elastic suspension mechanism is configured to be detachably installed between the housing 1 and the oscillator. (Referring to...) Figure 8 As shown, the entire elastic suspension mechanism can be independently disassembled from housing 1 to facilitate the replacement of different types of elastic suspension mechanisms as needed.

[0065] In one embodiment, each individual support spring 115 within each elastic suspension mechanism can be independently controlled to connect or disconnect from the oscillator, so as to control an appropriate number of support springs 115 to participate in power generation as needed; Reference Figures 8-9 As shown, the elastic suspension mechanism includes an upper connecting plate 111, a lower connecting plate 112, and several main telescopic rods 113 located between the upper connecting plate 111 and the lower connecting plate 112. The upper connecting plate 111 is connected to the oscillator, and the lower connecting plate 112 is connected to the housing 1. When the oscillator moves up and down, the main telescopic rods 113 simultaneously extend and retract via the upper connecting plate 111. (Refer to...) Figure 8As shown, a central telescopic rod 114 can be set at the center of the upper connecting plate 111 and the lower connecting plate 112. The central telescopic rod 114 is coaxially set with the flywheel mechanism 6 and is used to guide the stable up and down vibration of the entire elastic suspension mechanism. Each main telescopic rod 113 is equipped with a support spring 115 and an auxiliary telescopic rod 116. The support spring 115 is coaxially sleeved on the main telescopic rod 113. One end of the support spring 115 is connected to the housing 1, and the length of the support spring 115 is less than the length of the main telescopic rod 113 when fully extended. The auxiliary telescopic rod 116 is set in the same direction as the main telescopic rod 113. One end of the auxiliary telescopic rod 116 is connected to the upper connecting plate 111, and the other end faces the support spring 115. A locking member is installed at the other end of the auxiliary telescopic rod 116. The auxiliary telescopic rod 116 is configured to be locked to the support spring 115 by the locking member after extension, or to retract and disengage from the support spring 115 after unlocking by the locking member.

[0066] Connection operation: Control the extension of the auxiliary telescopic rod 116 so that the locking part contacts the end of the support spring 115, and start the locking part to perform the locking operation, connecting the auxiliary telescopic rod 116 to the support spring 115. At this time, the movement of the oscillator can synchronously drive the connected support spring 115 to move synchronously.

[0067] Disengagement operation: Activate the locking mechanism to perform the unlocking operation, separating the auxiliary telescopic rod 116 from the support spring 115. Then, the auxiliary telescopic rod 116 retracts to its initial state. At this time, the oscillator drives the oscillator and the main telescopic rod 113 to move.

[0068] Based on the above connection and disconnection operations, an appropriate number of support springs 115 and corresponding auxiliary telescopic rods 116 can be connected as needed, thereby flexibly controlling an appropriate number of support springs 115 to participate in power generation. In order to improve stability, an even number of symmetrical support springs 115 can be set to participate in the operation.

[0069] refer to Figures 8-10As shown, a receiving plate 117 is installed on the end of the supporting spring 115 facing the auxiliary telescopic rod 116. The receiving plate 117 has several connecting grooves on the side facing the auxiliary telescopic rod 116. Each connecting groove includes an interconnected insertion hole 118 and a locking groove 119. The width of the opening of the locking groove 119 is smaller than the diameter of the insertion hole 118. The locking component includes a connecting plate 121, a rotating disk 122, and a driving structure 123. The connecting plate 121 is installed on the other end of the auxiliary telescopic rod 116. The rotating disk 122 is rotatably mounted on the connecting plate 121 facing the auxiliary telescopic rod 116. On the side of the supporting spring 115, a number of insert rods 124 are installed on the rotating disk 122 facing the supporting spring 115. The end of the insert rod 124 is provided with a limit ball 125. The auxiliary telescopic rod 116 extends to control the limit ball 125 to enter the insertion hole 118. The drive structure 123 is used to drive the rotating disk 122 to rotate and control the limit ball 125 inserted into the insertion hole 118 to rotate into the locking groove 119. The locking groove 119 restricts the limit ball 125 from disengaging and locks the rotating disk 122 and the receiving disk 117 in a locked state.

[0070] For the drive structure 123, a conventional motor and gear set can be used. For example, a gear disk is coaxially installed inside the rotating disk 122, the motor is mounted on the connecting plate 121, the output shaft of the motor is equipped with a drive gear, the drive gear meshes with the gear disk, the motor controls the rotation of the drive gear, thereby driving the gear disk to rotate, and thus controlling the rotation of the rotating disk 122. The installation position of the motor and gear disk is not limited, as long as it can realize the independent rotation of the rotating disk 122 as needed.

[0071] refer to Figure 8 As shown, multiple auxiliary telescopic rods 116 can be set around each main telescopic rod 113, and at least one auxiliary telescopic rod 116 is configured to be electrically controlled for telescopic movement, such as an electric telescopic rod structure; the movement of the locking component can be stably controlled by multiple auxiliary telescopic rods 116.

[0072] In one embodiment, reference Figure 10 As shown, lever 131 positioning structures are provided in each connecting groove within the receiving plate 117. Each lever 131 positioning structure includes a lever 131, one end of which is located within the locking groove 119, and the other end extends into the center hole of the receiving plate 117. An anti-slip layer 132 is provided on the extended section of the lever 131. The lever 131 is configured as follows:

[0073] The center of lever 131 is fixed by a torsion spring and a torsion spring shaft 133. In its natural state, the extension of lever 131 extends into the center hole of receiving plate 117 and is in close contact with the surface of main telescopic rod 113 through anti-slip layer 132. This stabilizes the state of spring 115 and prevents unconnected springs from vibrating during operation, affecting overall stability and subsequent connection operations.

[0074] When the limiting ball 125 rotates to the locking groove 119, it squeezes one end of the lever 131 and controls the extension of the lever 131 to swing away from the surface of the main telescopic rod 113. The anti-slip layer 132 is separated from the surface of the main telescopic rod 113. At this time, the support spring 115 is in the connected state, and one end of the support spring 115 can move up and down with the oscillator.
