Description

Technical Field

[0001] The invention belongs to the field of renewable energy in marine engineering, and in particular relates to a wave self-regulating bistable electromagnetic-friction power generation device. Background Art

[0002] Wave energy is a largely untapped renewable energy source with great potential. It has little impact on the environment and has the advantages of large energy storage, high density, and wide distribution. However, although many researchers have conducted extensive research on wave energy harvesting technology, these existing studies cannot be directly applied to hull wave energy harvesting due to the following problems:

[0003] 1. Existing energy harvesting devices only perform better at higher excitation amplitudes and frequencies, while sea waves are mostly low-frequency, resulting in low energy capture efficiency.

[0004] 2. Existing energy collection devices have low efficiency in converting mechanical energy into electrical energy, generally generate electricity in a single form, and have a complex transmission structure.

[0005] 3. The overall mechanical structure of existing energy collection devices is generally complex and costly, and cannot be directly used on the hull.

[0006] The application of nonlinear mechanisms is one of the methods to improve the energy capture efficiency of point absorption wave energy converters. Among different nonlinear mechanisms, bistable mechanisms have been widely studied in the field of vibration energy harvesting. The bistable system has two stable equilibrium points and one unstable equilibrium point, which form two potential wells separated by a potential barrier. Under different wave excitations, oscillations within the well and between wells will occur. Many researchers have proved that the bistable system that can overcome the potential barrier to oscillate between wells has better energy capture efficiency than the linear system. However, the existing bistable system has a fixed potential barrier. When the excitation force is small, it is difficult to cross the potential barrier and move within the well, resulting in poor power capture efficiency. Summary of the invention

[0056] Based on the above, the specific value of M is 9.

[0057] When in use, the device is fixed on a sailing ship, and the device moves with the ship. Due to inertia and system damping, the mass block 21 of the device moves up and down relative to the housing body 1. Before the device works, the piston assembly 241 is in a horizontal state, and the piston cylinder 2414 is divided into two sides by the piston 2415. The side close to the leaf spring 243 is the air chamber 1, and the side close to the mass block 21 is the air chamber 2. The pressure of the air chamber 1 and the air chamber 2 of the piston assembly 241 is adjusted by the cylinder 245, so that the pressure of the air chamber 1 is greater than the pressure of the air chamber 2, and when the mass block 21 moves up and down, the pressure of the air chamber 1 is always greater than the pressure of the air chamber 2 during the movement of the piston 2415 toward the mass block 21. Therefore, the self-adjusting bistable mechanism 24 provides a vertical upward component when the mass block 21 moves upward from the static equilibrium position, and provides a vertical downward component when the mass block 21 moves downward from the static equilibrium position, thereby expanding the movement amplitude of the mass block 21.

[0058] Specific analysis: The specific motion process of the device includes the following five special motion states. The self-regulating bistable mechanism 24 has a potential barrier and potential wells distributed on both sides of the potential barrier. The potential barrier corresponds to the moment when the mass block 21 is in a static equilibrium position. Fig.15 is a state diagram of the mass block 21 in a static equilibrium position, and the potential well corresponds to the moment when the mass block 21 is located at the upper and lower sides of the static equilibrium position. Fig.14 is a state diagram when the mass block 21 is in the first position corresponding to the first potential well, Fig.16 It is a state diagram when the mass block 21 is in the second position corresponding to the second potential well. Fig.13 It is a state diagram when the mass block 21 is at the upper limit position, that is, the highest position that the mass block 21 can reach upward. Fig.17 It is a state diagram when the mass block 21 is at the lower limit position, that is, the lowest position that the mass block 21 can reach downward.

[0059] When the mass block 21 moves downward along the guide rod 22 relative to the shell body 1, the piston connector 246 fixedly connected to the mass block 21 moves downward together with the mass block 21, and the piston assembly 241 connected to the piston connector 246 moves downward together. Since the fastening assembly 242 is fixed on the leaf spring 243, the fastening assembly 242 will not move downward together. Since the mass block 21 and the piston rod connecting piece 2411 are connected by rotation via the second optical axis 2417, the entire piston assembly 241 will also rotate around the second optical axis 2464, that is, the piston assembly 241 has both downward displacement and rotation. When the mass block 21 moves downward from the upper limit position to the static equilibrium position, the piston rod 2412 and the piston 2415 slide toward the first optical axis 2424. At this time, the volume of air chamber 1 decreases and the pressure increases, the volume of air chamber 2 increases and the pressure decreases, and the vertical upward component force provided by the self-adjusting bistable mechanism 24 first increases and then decreases. When it is equal to 0 at the static equilibrium position, the fastening assembly 242 will drive the middle part of the leaf spring 243 to move horizontally away from the mass block 21. At the same time, the upper end of the leaf spring 243 is connected to the leaf spring connector 244 fixed at the lower end of the partition 13 through the ear 2431. The ear 2431 will rotate and move downward around the leaf spring connector 244, and the lower end cylinder 2432 of the leaf spring 243 will only rotate around the leaf spring connector 244 fixed on the lower end cover 14. In this process, the potential barrier continues to decrease. When it reaches the static equilibrium position, the potential barrier is the lowest. The mass block 21 is easier to cross the static equilibrium position; when the mass block 21 approaches the lower limit position downward from the static equilibrium position, the piston rod 2412 and the piston 2415 slide in the direction away from the first optical axis 2424. At this time, the volume of the air chamber 1 increases and the pressure decreases, the volume of the air chamber 2 decreases and the pressure increases, and the vertical downward component force provided by the self-adjusting bistable mechanism 24 first increases from 0 and then decreases. Since the direction of the component force is consistent with the movement direction of the mass block 21, the movement amplitude of the mass block 21 is enlarged, and the fastening assembly 242 will drive the middle part of the leaf spring 243 to move horizontally toward the direction of the mass block 21. At the same time, the ear 2431 will rotate and move upward around the leaf spring connector 244, and the lower end cylinder 2432 of the leaf spring 243 will only rotate around the leaf spring connector 244 fixed on the lower end cover 14. During this process, the potential barrier continues to rise, and the potential barrier is the highest when it reaches the lower limit position. During reverse motion, when the mass block 21 moves upward from the lower limit position to the static equilibrium position, the potential barrier continues to decrease until it reaches the lowest level at the static equilibrium position, and when it moves upward from the static equilibrium position to the upper limit position, the potential barrier continues to increase until it reaches the highest level at the upper limit position. In the entire device, the self-regulating function of the self-regulating bistable mechanism 24 is reflected in the continuous decrease and increase of the potential barrier. During the process of the mass block 21 approaching the static equilibrium position from the upper limit position or the lower limit position, the potential barrier continues to decrease until it reaches the lowest level at the static equilibrium position, and during the process of the mass block moving away from the static equilibrium position and approaching the upper limit position or the lower limit position, the potential barrier continues to increase until it reaches the highest level at the upper limit position or the lower limit position.The variability of this potential barrier enables the self-regulating bistable mechanism to oscillate between wells, thereby increasing the motion amplitude of the mass block 21. If the self-regulating bistable mechanism is not used, the mass block 21 cannot cross the potential barrier, the motion amplitude cannot be amplified, and the energy capture effect is poor.

[0060] Since the first one-way bearing 331 and the second one-way bearing 332 are installed in opposite directions, so that they rotate in opposite directions, it is assumed that the first one-way bearing 331 starts working only when the screw 26 tends to rotate clockwise relative to the coil flywheel 312, and the second one-way bearing 332 starts working only when the screw 26 tends to rotate counterclockwise relative to the magnet flywheel 311. When the mass block 21 is located at the upper side of the static equilibrium position close to the first position and the lower side of the static equilibrium position close to the second position, it is in an acceleration state, and the upper side of the static equilibrium position is far away from the first position and the lower side of the static equilibrium position is far away from the second position, it is in a deceleration state. When the mass block 21 reaches the first position and the second position, the speed is the maximum. Fig.13 As shown, the mass block 21 is at the upper limit position, that is, the highest position that the mass block 21 can reach upward. When the mass block 21 starts to move downward from the upper limit position, the mass block 21 drives the screw 26 to rotate clockwise. Figure 13 to Figure 14 , the mass block speed increases from 0 to approach the first position corresponding to the first potential well and the speed is the maximum at the first position, the screw 26 rotates clockwise and the angular velocity increases from 0, and the angular velocity of the screw 26 reaches the maximum value when the mass block 21 reaches the first position. During this period, when the screw 26 tends to rotate clockwise relative to the coil flywheel 312, the first one-way bearing 331 starts to work, and the screw 26 drives the coil flywheel 312 to rotate together through the first one-way bearing 331. Figure 14 to Figure 15 When the mass block 21 moves away from the first position and approaches the static equilibrium position, the speed of the mass block 21 approaches the static equilibrium position in the form of decreasing speed, and the screw 26 rotates clockwise with the angular velocity decreasing continuously. During this period, since the angular velocity of the screw 26 decreases faster than the angular velocity of the coil flywheel 312, the screw 26 rotates counterclockwise relative to the coil flywheel 312, and the first one-way bearing 331 does not work and is in an intermittent period. At this time, the screw 26 idles. When the mass block 21 moves away from the static equilibrium position and approaches the second position corresponding to the second potential well, as shown in FIG. Figure 15 to Figure 16 , the speed of the mass block 21 approaches the second position in the form of increasing speed, the screw 26 rotates clockwise and the angular velocity increases continuously, and the angular velocity of the screw 26 is the maximum when the mass block 21 reaches the second position. During this period, when the screw 26 tends to rotate clockwise relative to the coil flywheel 312, the first one-way bearing 331 starts to work, and the screw 26 drives the coil flywheel 312 to rotate together through the first one-way bearing 331. When the mass block 21 moves away from the second position and reaches the lower limit position, as shown in FIG. Fig.17As shown, the lower limit position is the lowest position that the mass block 21 can reach downward, such as Figure 16 to Figure 17 , the speed of the mass block 21 gradually decreases to 0, the screw 26 rotates clockwise and the angular velocity continues to decrease to 0. During this period, because the angular velocity of the screw 26 decreases faster than the angular velocity of the coil flywheel 312, the screw 26 rotates counterclockwise relative to the coil flywheel 312, and the first one-way bearing 331 does not work. In the intermittent period, the screw 26 idles. Throughout the entire descent process of the mass block 21 from the upper limit position, the first position, the static equilibrium position, the second position to the lower limit position, the screw 26 always rotates clockwise, and the magnet flywheel 311 still keeps rotating counterclockwise due to inertia, then the screw 26 rotates clockwise relative to the magnet flywheel 311, and the second one-way bearing 332 does not work at all. In particular, when the first one-way bearing 331 is in the intermittent period, the screw 26 idles.

[0061] The rotation of the coil flywheel 312 drives the second organic glass disc layer 3215, the second nano-surface copper mold layer 3214, the dielectric film layer 3213 and the first conductive slip ring 313 fixedly connected thereto to rotate synchronously. The rotation of the magnet flywheel 311 drives the first organic glass disc layer 3211, the first nano-surface copper mold layer 3212 and the second conductive slip ring 322 fixedly connected thereto to rotate synchronously. The relative rotation of the coil flywheel 312 and the magnet flywheel 311 drives the first nano-surface copper mold layer 3212 and the dielectric film layer 3213 to rotate relative to each other. Due to the existence of the fan-shaped hollowing portion 3216, the contact area between the first nano-surface copper mold layer 3212 and the dielectric film layer 3213 changes in a cycle of decrease-increase-decrease-increase, thereby generating alternating current. The first conductive slip ring 313 and the second conductive slip ring 322 are connected to the rectifier circuit, so that direct current can be used.

[0062] When the mass block 21 moves in the reverse direction, the screw 26 always rotates counterclockwise, and the coil flywheel 312 still keeps rotating clockwise due to inertia. When the screw 26 rotates counterclockwise relative to the coil flywheel 312, the first one-way bearing 331 does not work at all. In particular, when the second one-way bearing 332 is in the intermittent period, the screw 26 rotates idly. Similarly, the relative rotation of the coil flywheel 312 and the magnet flywheel 311 causes the first nano-surface copper mold layer 3212 and the dielectric film layer 3213 to rotate relative to each other. Due to the presence of the fan-shaped hollowing portion 3216, the contact area between the first nano-surface copper mold layer 3212 and the dielectric film layer 3213 changes in a cycle of decrease-increase-decrease-increase, thereby generating alternating current.
