[0033] The present invention is described in detail below in conjunction with the accompanying drawings:

[0034] Example, combined with Figures 1 to 6 A floating system for offshore charging piles based on HDPE floating breakwaters includes a floating breakwater 1, a floating platform 2, a power generation device, a battery pack 3, a charging pile 4, a data center 5, and a control unit. The floating breakwater 1 is a circular ring structure with a gap. The floating breakwater 1 is connected to the seabed through multiple groups of anchor cables 13. The floating breakwater 1 floats on the sea surface, and an area suitable for ships to dock and charge is formed inside the floating breakwater 1. The gap direction of the floating breakwater 1 is determined according to the wind rose diagram of the sea area where the offshore charging pile floating system is anchored, that is, the gap of the floating breakwater 1 deviates from the incident direction of the dominant waves in the sea area, so as to reduce the waves from entering its internal area through the gap of the floating breakwater 1.

[0035] The floating breakwater 1 includes a plurality of HDPE pontoon modules 11, all of which are arranged in sequence at equal intervals along the circumferential direction, and any two adjacent HDPE pontoon modules 11 are movably connected via a wave-breaking plate 12, and some of the HDPE pontoon modules 11 are respectively provided with a set of anchor cables 13 and connected to the seabed via the anchor cables 13.

[0036] Specifically, the HDPE pontoon module 11 is an inverted L-shaped integrated structure consisting of a pontoon monomer 1 111 and a pontoon monomer 2 112 , and both the pontoon monomer 1 111 and the pontoon monomer 2 112 are strip structures with square cross-sections.

[0037] All pontoon monomers 111 are arranged horizontally in their length direction along the normal direction of the floating breakwater 1, and pontoon monomers 112 are arranged vertically, with their upper ends fixedly connected to the bottoms of pontoon monomers 111. One end of pontoon monomer 111 away from the floating platform 2 protrudes outward relative to pontoon monomer 2 112 below it, and has a better ability to resist waves. The impact of waves will be reflected upward and outward, reducing the impact of the next wave.

[0038] The wave-breaking plate 12 is a curved rectangular parallelepiped, which is vertically arranged between two HDPE pontoon modules 11, and its arc-shaped convex surface is located on the side away from the floating platform 2. The middle and upper part of the wave-breaking plate 12 has a plurality of regularly distributed circular through holes 14, and the two sides are respectively connected to the side walls of adjacent HDPE pontoon modules 11 through a set of universal hinges, each set of universal hinges 15 includes two universal hinges 15 arranged one above and one below, specifically, one end of the universal hinge 15 is fixedly connected to the side wall of the wave-breaking plate 12, and the other end is fixedly connected to the side wall of the pontoon monomer 111, and the two adjacent HDPE pontoon modules 11 are flexibly connected through the wave-breaking plate 12, which greatly reduces the wave height in the internal area of ​​the floating breakwater 1 and reduces the intensity of the sea waves after passing through the floating breakwater 1.

[0039] The end surface of the first pontoon monomer 111 has a rectangular groove, which extends to the upper surface or lower surface of the first pontoon monomer 111. The upper part of the second pontoon monomer 112 has the same plurality of circular through holes 14. The wave-breaking plate 12 and the circular through holes 14 on the second pontoon monomer 112 can absorb tidal energy and further block the transmission of sea waves.

[0040] The first and last HDPE pontoon modules 11 are each configured with a set of anchor cables 13, and the HDPE pontoon modules 11 in the middle positions are also configured with a set of anchor cables 13. Each set of anchor cables 13 includes three anchor cables 13 with configurations, and the upper ends of the three anchor cables 13 in the same set are connected to the middle position of the bottom of the corresponding HDPE pontoon module 11, and the lower ends are respectively connected to a suction cylinder, and the three suction cylinders are arranged in an equilateral triangle and fixed on the seabed.

[0041] The number of anchor cables 13 used to connect the floating breakwater 1 to the seabed can be determined according to the wave intensity and frequency reflected by the wind rose diagram of the sea area. When the wave intensity is large and / or the wave frequency is high, the number of anchor cables 13 can be appropriately increased to ensure that the floating breakwater 1 maintains a circular structure, which is crucial for reducing the wave height inside it. A group of anchor cables 13 arranged in an equilateral triangle can minimize the position deviation of the HDPE pontoon module 11 on the sea surface to avoid affecting the stability of the overall structure. The change in the size of the gap of the floating breakwater 1 is controlled within a small range to avoid affecting the entry and exit of ships.

[0042] The floating platform 2 is arranged at the center of the floating breakwater 1, and six anchor chains 23 are arranged at the bottom thereof. The floating platform 2 is a vertically arranged hollow shell 21, and the interior of the floating platform 2 has an independent ballast water tank 201 and a control cabin 202. The ballast water tank 201 is located below the control cabin 202. The battery pack 3 and the data center 5 are both arranged inside the control cabin 202. The battery pack 3 uses a lithium iron phosphate battery pack, and the data center 5 is equipped with a water cooling system to achieve cooling by heat exchange with seawater.

[0043] Specifically, the upper part of the floating platform 2 is cylindrical and the lower part is conical, and the upper end thereof has a top cover 25 that closes the internal cavity, and the inner middle part of the floating platform 2 has a partition 22, and the partition 22 divides the interior of the floating platform 2 into the ballast water tank 201 and the control cabin 202. The control cabin 202 is a closed structure, which provides buoyancy for the floating platform 2 so that the top of the floating platform 2 is always above the sea surface, avoiding the impact of seawater on the charging pile 4.

[0044] The lower part of the floating platform 2 has an inlet and outlet pipe connected to the ballast water tank 201, and the inlet and outlet pipe is equipped with a submersible pump and an electric control valve. The signal ends of the submersible pump and the electric control valve are both connected to the data center 5. The ballast water tank 201 is filled with seawater as a ballast to keep the floating platform 2 vertical and stable. The wave radar is installed above the floating platform 2, which can scan the wave height of the berth area around the floating platform 2 and the roll angle of the floating platform 2 in real time, and dynamically adjust the water volume in the ballast water tank 201 through the submersible pump to change the height of the center of gravity of the floating platform 2, so that the roll angle of the floating platform 2 is controlled within ±5°, and the stability and safety of the ship's charging at sea are maintained.

[0045] All anchor chains 23 are evenly arranged in a ring shape below the floating platform 2. The lower inner side of the floating platform 2 is provided with equipment cabins 203 equal in number to the anchor chains 23 and corresponding in position. A winch mechanism 24 is disposed inside each equipment cabin 203. The winch mechanism adopts a ship winch already available in the prior art.

[0046] The upper end of each anchor chain 23 passes through the outer wall of the floating platform 2 and enters the corresponding equipment cabin 203, and is connected to the hoisting mechanism 24 in the equipment cabin 203. The lower end is connected to an anchor foundation, and all anchor foundations are evenly distributed in a ring shape and fixed on the seabed. The interior of the equipment cabin 203 is divided into two areas by a steel plate, one of which is used to install the drum of the hoist, which is connected to the outside, and the other is a closed area for installing the stepper motor and reducer of the hoist. The reducer is connected to the drum through a transmission shaft, and the transmission shaft is in rotation with the steel plate. The signal end of each stepper motor is respectively connected to the data center 5, and the data center 5 controls the working state of all stepper motors through instructions. When the floating platform 2 descends or rises, each winch works synchronously to tighten or release the anchor chain 23, so that the anchor chain 23 is in the optimal tension state.

[0047] There are multiple charging piles 4, which are evenly arranged in a ring shape on the top of the floating platform 2. Each charging pile 4 is powered by the battery pack 3. The output power of the charging pile 4 is 200kW. Each charging pile 4 is equipped with a ship CCS standard charging interface for replenishing electrical energy for the ship.

[0048] The power generation device includes a wind turbine 61 and a solar photovoltaic module 62. There are multiple wind turbines 61, which are regularly installed on the top of the floating platform 2. A solar photovoltaic module 62 is provided on the top of each HDPE pontoon module 11. The wind turbine 61 and the solar photovoltaic module 62 are both electrically connected to the battery group 3.

[0049] The solar photovoltaic assembly 62 includes a photovoltaic panel and a follower bracket. The photovoltaic panel is installed above the pontoon unit 111 through the follower bracket. The output end of the photovoltaic panel is connected to the battery group 3 via the MPPT controller and the submarine cable. The follower bracket is equipped with a servo motor that can adjust the tilt angle of the photovoltaic panel so that the photovoltaic panel can automatically track the solar azimuth.

[0050] The electric energy output by the wind turbine 61 is combined with the electric energy output by the photovoltaic panel through the AC / DC converter, and is charged to the battery pack 3 through the bidirectional converter or directly supplied to the charging pile 4 .

[0051] The control unit includes a posture sensor, a wave radar and an AI scheduling module, which are respectively connected to the data center 5. The data center 5 is equipped with an edge computing module, each solar photovoltaic module 62 is equipped with a posture sensor, the wave radar is installed above the floating platform 2 to monitor the wave intensity of each berth outside the floating platform 2, and the AI ​​scheduling module commands the ship to enter the predetermined berth.

[0052] When the wind speed and light conditions are good, the AI ​​scheduling module starts the wind turbine 61 and the solar photovoltaic module 62, and the attitude sensor controls the photovoltaic panel to reach the optimal angle, thereby realizing the combined power generation of wind and photovoltaic, and directly supplies the electric energy to the charging pile 4 and the battery pack 3 for charging and energy storage; when the ship passes through the gap of the floating breakwater 1 and enters its internal area, the wave radar detects the wave intensity of each berth, and the AI ​​scheduling module directs the ship to enter the predetermined charging position for charging. During the charging process, the wave radar (detection frequency X band) scans the wave height of the berth area in real time. When the effective wave height is detected to be greater than 1.5m, the AI ​​scheduling module starts the following actions:

[0053] Instruct the counterweight water tank 201 to inject seawater (maximum adjustment rate 10m 3 / min), lower the center of gravity of the floating platform 2, and the winch mechanism 24 dynamically adjusts the tension of each anchor chain 23 to a preset safety threshold (120-150kN). If the roll angle is detected to be greater than 4°, charging is immediately suspended and an audible and visual alarm is triggered.
