[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] See also Figure 1-3The present invention provides a technical solution: a passive indicator light on the water, including an indicator light 1, a power generation chamber 23 and a float 2, a generator 3, an energy storage device 27 and a linear motor stator 4 of the generator 3 are provided in the power generation chamber 23, the generator 3 is a permanent magnet linear motor, the generator 3 includes a matching linear motor mover 5 and a linear motor stator 4, the linear motor mover 5 is sleeved on the outside of the power generation chamber 23, and the float 2 is fixedly installed on the linear motor mover 5, so a stabilizing device for making the float 2 float up and down more stably is provided outside the power generation chamber 23, and the stabilizing device includes a horizontal stabilizing component and a longitudinal stabilizing component; it should be noted that: the different permanent magnets are optimized by the permanent magnet simulation design technology. The magnetic induction intensity curve simulation of the directional path shows that the location of the permanent magnet with the largest external magnetic induction intensity and the densest magnetic flux lines can be located. Therefore, the external coil winding can be placed in the corresponding location, which can improve the utilization rate of the permanent magnet and make it more conducive to the device to generate induced electromotive force, with low system loss and high efficiency. The power post-processing circuit is simple and the overall system size is small. The components used in the system's power post-processing circuit are all very small and highly integrated components and modules. Through reasonable design, the overall system size can be kept small, which is convenient for product placement and use. The project uses passive rectification to process the motor output variable frequency and voltage power, and combines it with a passive storage circuit to mainly achieve rectification and voltage stabilization. The overall power post-processing circuit includes a rectifier and filter module, a voltage stabilization circuit module, a charging circuit module, a battery module, an energy-consuming load module, and a control module. The variable-frequency and variable-amplitude electrical energy generated by the wave energy generation system is primarily converted into a DC voltage using a rectifier and filter circuit. This energy is then stepped down through a buck circuit and stored in capacitors. This energy is primarily used to drive the LEDs that consume the energy, operate the control module, and charge the charging circuit module. In terms of system stability design, the MPPT control method is primarily employed to ensure overall system stability and high efficiency. Dual-disturbance MPPT control is employed, varying the system voltage by adjusting the duty cycle. The system current changes with the voltage, controlling the motor shaft stator current to optimize the electromagnetic force in the motor. This in turn adjusts the active power output of the power generation system to track the maximum power point, thereby optimizing the power of the wave power generation system.

[0024] Specifically, the floats 2 are symmetrically arranged on both sides of the power generation chamber 23, the stabilizing device includes a base plate 6 connected between the two floats 2, and fixed rods 7 are symmetrically extended downward on both sides of the base plate 6. The horizontal stabilizing assembly is provided with two groups, and is respectively provided on the end faces of the two fixed rods 7 close to each other. The horizontal stabilizing assembly includes a balancing box 8 provided on the fixed rod 7, and a water flow channel 9 is opened on the front and rear sides of the balancing box 8. The horizontal stabilizing assembly also includes a balancing plate 10 that slides horizontally in the balancing box 8. The balancing plate 10 is provided on the side of the water flow channel 9 away from the fixed rod 7. The horizontal stabilizing assembly also includes a spring 11 provided in the inner cavity of the balancing box 8, and one end of the spring 11 is fixed to the inner cavity of the balancing box 8 away from the fixed rod 7. One end surface of the balance plate 10, the other end of the spring 11 is fixed to the end surface of the side of the balance plate 10 away from the fixed rod 7, and the spring 11 is always in a compressed state; when the water flow at sea drives the base plate 6 to move toward one side in the horizontal direction, the water flow will be diverted to both sides of the fixed plate by the fixed rod 7. After flowing through the fixed plate, the water flow will gather again and flow through the water channel 9, thereby hitting the balance plate 10, causing the balance plate 10 to compress the spring 11. After the spring 11 is compressed, it will push the balance plate 10 to slide toward the side of the water flow. Under the reaction force of the balance plate 10, the base plate 6 will slide in the opposite direction of the water flow, thereby forming a balance with the direction in which the water flow drives the base plate 6 to slide, which helps the float 2 to more purely absorb the up and down vibration force of the sea water.

[0025] Specifically, a sliding groove 12 is opened on the inner wall of the balancing box 8 , and the upper and lower ends of the balancing plate 10 are respectively fitted in the sliding groove 12 . The balancing plate 10 forms a sliding connection with the balancing box 8 through the fitting of the sliding groove 12 .

[0026] Specifically, a main rod 13 extends downward from the middle of the base plate 6. The longitudinal stabilization assembly includes a horizontal rod arranged at the bottom end of the main rod 13, and a balance block 15 sliding horizontally in the horizontal rod. The balance blocks 15 are symmetrically arranged on both sides of the main rod 13. The main rod 13 is provided with fasteners for keeping the balance blocks 15 in their initial state. The longitudinal stabilization assembly also includes a pulling assembly that drives the slider out of its initial position to make the float 2 more stable. Through the sliding arrangement of the balance block 15 on the horizontal rod, when the sea water first drives one side of the base plate 6 to move upward, the balance block 15 on the side that moves upward first will move outward under the action of the pulling assembly, thereby increasing the weight of the base plate 6 on the side that moves upward first, so that the forces on both sides of the base plate 6 are more balanced, so that the float 2 is better in a state of nearly floating up and down.

[0027] Specifically, the main rod 13 continues to extend toward the lower end of the horizontal rod, and the pulling assembly includes a driving plate 16 symmetrically arranged on both sides of the bottom end of the main rod 13. The driving plate 16 is rotatably connected to the main rod 13. The bottom end of the main rod 13 is also provided with a limit plate 17 that enables the driving plate 16 to maintain a balanced state in a natural state. The pulling assembly also includes a connecting rope 18, one end of the connecting rope 18 is fixedly connected to the balance block 15, and the other end of the connecting rope 18 is fixedly connected to the driving plate 16. It should be noted that: the bottom ends of the horizontal rod and the main rod 13 are both provided with guide wheels for the connecting rope 18 to better connect the balance block 15 and the driving plate 16. When one side of the driving plate 16 is preferentially impacted upward by the flow of seawater and rotates upward, the driving plate 16 pulls the connecting rope 18, thereby pulling the balance block 15 toward the side away from the main rod 13, thereby achieving the effect of better balancing the two sides of the substrate 6.

[0028] Specifically, a sliding groove 19 is provided in the balancing rod, and the balancing block 15 is horizontally slidably arranged in the sliding groove 19 .

[0029] Specifically, the fastener includes a fastening spring 20, one end of which is fixed to the inner wall of the sliding groove 19 close to the main rod 13, and the other end of the fastening spring 20 is fixed to the end face of the balance block 15 close to the main rod 13. By setting the fastening spring 20, when the upper and lower buoyancy forces on the floating plates on both sides are relatively balanced, the fastening spring 20 will pull the balance block 15 to slide to its initial position.

[0030] Specifically, limiting grooves 21 are symmetrically provided on both sides of the limiting plate 17, and a limiting spring 22 is fixed at the bottom end of the limiting groove 21. The other end of the limiting spring 22 is fixed on the driving plate 16. When the upper and lower buoyancy forces on the floating plates on both sides are relatively balanced, the limiting spring 22 will pull the driving plate 16 to fit together with the limiting plate 17, thereby maintaining a horizontal state.

[0031] Specifically, a sealing plate 24 is provided at the lower end of the power generation chamber 23, and a sealing layer 25 is provided at the upper end of the power generation chamber 23. The sealing plate 24 and the sealing layer 25 isolate the power generation chamber 23 into a sealed chamber 26. The energy storage device 27 and the linear motor stator 4 are located in the sealed chamber 26. The provision of the sealing plate 24 and the sealing layer 25 can place the generator 3 in a sealed environment, thereby solving the problem of difficulty in sealing the generator 3 underwater.

[0032] A specific application example of this embodiment is:

[0033] When the device is in use, the water flow drives the float 2 to move up and down, thereby driving the linear motor rotor 5 to move up and down, so that the winding in the linear motor stator 4 cuts the magnetic lines of force in the linear motor rotor 5, and generates electricity through the generator 3. The electric energy generated by the generator 3 is stored in the energy storage device 27 (it should be noted that before the electric energy is stored in the energy storage device 27, it first passes through the rectifier filter module, the voltage stabilizing circuit module, the charging circuit module, the battery module, the energy consumption load module and the control module to rectify and stabilize the electric energy). When the float 2 floats up and down, if the water flow drives the float 2 to move horizontally, the balance plate 10 on one side of the horizontal pressure stabilizing assembly will be affected by the water flow passing through the water flow channel 9. The impact squeezes the spring 11, so that the spring 11 forms a reverse force on the balance plate 10 and pushes the balance plate 10 to slide to one side of the water flow and push the water flow, so that the base plate 6 forms a direction movement with the direction of the water flow, so that the float 2 maintains a good balance and is not easily driven horizontally by the water flow; when the water flow drives the floats 2 on both sides to float up successively instead of at the same time, the driving plate 16 on the side that floats up first will be rotated by the impulse of the water flow, thereby pulling the balance block 15 to slide outward through the connecting rope 18, thereby increasing the gravity of the side that floats up first, so that the side that floats up later maintains a good balance with the side that floats up first, so that the floats 2 on both sides can better absorb the tidal energy of the up and down vibration generated by the water flow at the same time to generate electricity and store energy.
