[0019] like Figure 1As shown, a floating-opening wave-breaking and power generation integrated device based on wave and current action in this embodiment includes a floating cylinder 1, a wave-breaking plate 2, a power generation module 3, an anchor chain 4, an intelligent monitoring system 41, and a self-adjusting system 42. The upper end of the floating cylinder 1 is open and the lower end is hollowed out, and a cross-beam support structure 13 is provided at the bottom of the floating cylinder 1. The cross-beam support structure 13 is a cross structure, which can enhance the stability of the floating body. The side wall of the floating cylinder 1 is provided with uniform side wall openings 12, which can weaken the direct impact of waves and currents on the floating cylinder 1, and play a preliminary wave-breaking and buffering effect. The wave-breaking plate 2 and the power generation module 3 are installed in the floating cylinder 1, and the power generation module 3 is installed on the cross-beam support structure 13. In this embodiment, a total of five power generation modules are arranged, which are respectively fixed at the center and four corners of the cross of the cross-beam support structure 13.

[0020] like Figure 2 As shown, the wave-breaking plate 2 is provided with a plurality of openings for energy dissipation, including four circles of openings arranged in sequence from the inside to the outside, each circle of openings is distributed along the circumference, and the opening rate on the wave-breaking plate 2 is 30%-50%. The opening area can produce a local energy dissipation effect, thereby effectively dissipating wave energy and reducing the reflection and impact of waves. This layout not only enhances the impact resistance of the floating structure, but also further improves the overall stability of the device through local energy dissipation, effectively reduces the destructive power of waves on surrounding facilities, and provides a reliable guarantee for efficient operation in the marine environment.

[0021] like Figure 3 As shown, the power generation module 3 includes a hollow mover 31, a slot stator 32, and a housing 35. The upper end of the housing 35 is open, and the slot stator 32 includes a plurality of slot units wound with coils, and the slot units are evenly arranged on the inner wall of the housing 35, and the housing 35 is fixed to the beam support structure 13. The hollow mover 31 includes a plurality of hollow magnetic poles with alternating magnetic arrangements.

[0022] like Figure 4 As shown, the power generation module 3 is connected to the wave-breaking plate 2 through a connecting shaft and realizes relative movement. The connecting shaft includes a central shaft 21 and a bottom fixed shaft 33. The top of the central shaft 21 is connected to the wave-breaking plate 2, and the hollow mover 31 is sleeved on the central shaft 21. The bottom of the bottom fixed shaft 33 is connected to the bottom of the shell 35. A slide groove is provided in the central shaft 21. The upper section of the bottom fixed shaft 33 is located in the slide groove. When the wave-breaking plate 2 and the power generation module 3 move relative to each other, the bottom fixed shaft 33 slides up and down in the slide groove. A spring 34 is provided on the outer side of the lower section of the bottom fixed shaft 33. The spring 34 is made of insulating material. The top of the spring 34 is connected to the central shaft 21, and the bottom is connected to the shell 35. The spring 34 can pull the central shaft 21 so that the central shaft and the bottom fixed shaft 33 do not separate. Under the action of waves and tides, the wave-breaking plate 2 and the power generation module 3 move relative to each other, and the hollow mover 31 and the tooth slot stator 32 cooperate to generate electricity, realizing efficient energy conversion.

[0023] All structures in contact with the liquid, including the floating cylinder structure 1, the beam support structure 13, the perforated wave-breaking plate 2, the central shaft 21, the toothed stator 32, the bottom fixed shaft 33 and the spring 34, are coated with corrosion-resistant coating materials to improve the corrosion resistance of the structure and ensure that the structure can operate for a long time.

[0024] The intelligent monitoring system 41 is arranged at the bottom of the side of the floating cylinder 1, and a pressure sensor or a hydraulic sensor can be used to measure the pressure or hydraulic pressure of the floating cylinder 1. The anchor chain 4 is connected to the bottom of the floating cylinder 1, and the anchor chain 4 is made of steel. The self-adjusting system 42 is used to control the retraction and extension of the anchor chain 4 according to the data of the intelligent monitoring system 41. When the hydraulic pressure value is detected to be large, the anchor chain can be appropriately lengthened to alleviate the impact on the floating cylinder 1; when the hydraulic pressure value is detected to be small, the anchor chain can be appropriately tightened to increase the impact force on the floating cylinder 1 and improve the power generation efficiency. By arranging the intelligent monitoring system 41 on the anchor chain 4 to obtain the impact force and hydraulic pressure under different working conditions at different times, the self-adjusting system 42 controls the tension and expansion of the anchor chain 4 according to the results of the intelligent monitoring system 41, and then controls the submerged depth of the floating cylinder 1 at the free liquid surface to ensure that the device remains balanced and stable under complex sea conditions. This dynamic adjustment mechanism can also optimize the wave-breaking effect of the device, while improving the power generation efficiency, ensuring that the device can operate efficiently under various sea conditions. Through precise feedback adjustment, the intelligent control system can achieve the best working state under changing waves and tidal currents, further improving the stability and performance of the device.

[0025] The present invention combines wave-breaking plates with power generation modules to partially absorb and dissipate wave energy, thereby reducing the impact of waves on equipment and achieving efficient power generation, thereby improving energy conversion utilization. The intelligent monitoring system and self-regulating system are used to achieve dynamic adjustment of the structure, further improving the wave-breaking effect and power generation efficiency of the device.
