[0016] An offshore ultra-large multi-module floating platform connector device with wave energy collection function, such as Figures 1-4 As shown, it includes a wave energy conversion and collection device, two floating units 1 and a liquid-filled rubber fender 4. The two floating units 1 are connected by the liquid-filled rubber fender 4, and the liquid-filled rubber fender 4 is connected to the wave energy conversion and collection device.

[0017] The two floating units 1 are connected by a flexible steel cable 3 , and flexible buffer springs 2 are provided at both ends of the flexible steel cable 3 . The flexible buffer springs 2 are provided inside the floating unit 1 .

[0018] Among them, the wave energy conversion and collection device includes a one-way valve 5, a relief valve 6, a rotor 7, an accumulator 8, a hydraulic motor 9, and a generator 10. The one-way valve 5, the relief valve 6, the rotor 7, the hydraulic motor 9, the generator 10, and the accumulator 8 are arranged in sequence on the pipeline connected to the liquid-filled rubber fender 4.

[0019] The liquid-filled rubber fenders 4 are arranged symmetrically in vertical and horizontal directions.

[0020] Wherein, the floating unit 1 is made of marine concrete material.

[0021] The flexible buffer spring 3 and the flexible steel cable 4 are made of steel and are treated with anti-corrosion and anti-rust treatment, which can effectively prevent seawater corrosion.

[0022] In a multi-module floating platform, a hydraulic module is placed between each floating unit. These modules are connected using flexible buffer springs, flexible steel cables, and a liquid-filled rubber fender 4. The flexible buffer springs and flexible steel cables support tension, while the liquid-filled rubber fender 4 supports pressure. The liquid-filled rubber fender 4 provides pressure-resistant impact protection and limits module movement, connecting the units together. The liquid-filled rubber fender 4 is equipped with a hydraulic wave energy conversion and collection device that converts wave energy into high-pressure hydraulic energy.

[0023] Adopting the basic principle of pendulum wave energy conversion device, the liquid-filled rubber fender 4 structure adopts a vertically symmetrical arrangement, which can effectively limit the relative rotation between modules, maintain the neutral position in calm sea conditions, and realize two-way wave energy collection, thereby increasing the wave energy collection efficiency.

[0024] This device offers excellent scalability and structural adaptability. The modular design of the multi-module floating platform units adapts to different platform interior shapes. The units can be increased or decreased based on actual needs to maximize efficiency. The connector components are standardized, allowing for platform-specific connections by installing different numbers of connectors for different floating module sizes. If a single module is damaged, only the corresponding module needs to be removed for repair, facilitating disassembly, repair, and installation of the power generation device.

[0025] The liquid-filled rubber fender 4 structure can realize dynamic adjustment of the stiffness and damping of the fender structure by cooperating with the hydraulic wave energy conversion and collection device, which can increase the adaptability to different sea conditions, effectively limit the movement of the module, and ensure the smooth operation of the platform.

[0026] The introduction and design of the wave energy conversion and collection device and the connector structure have a positive feedback effect, which can realize the collection and conversion of wave energy and increase the connection effect of the connector.

[0027] The design of the flexible buffer spring 2 and the flexible steel cable 3 can limit the range of motion of the multi-module floating unit, thereby preventing damage to the liquid-filled rubber fender caused by excessive stroke due to large movements in severe sea conditions.

[0028] The low-carbon and environmentally friendly design solution uses four hydraulic rubber fenders to absorb wave energy, which can be further converted into electrical energy through secondary conversion, providing the platform with a green renewable energy supply. Multiple sets of these wave energy conversion and collection devices can be used to generate electricity simultaneously in multi-stage wave energy device hydraulic circuits when sea conditions are good. During the up and down movement of the waves, the hydraulic oil in the flexible hydraulic fenders is alternately pumped out, fully utilizing wave energy and providing the platform with renewable clean energy.

[0029] The floating unit 1 can be made of marine concrete materials, and the flexible buffer spring 2 and the flexible steel cable 3 are made of steel, which needs to be treated with anti-corrosion and anti-rust.

[0030] The connector's main structure consists of a connecting steel cable (3) and a liquid-filled rubber fender (4). The steel cable supports tension, connecting the modules together. The fender provides pressure resistance, collision avoidance, and movement control. The liquid-filled fender can be designed with a hydraulic wave energy conversion and collection device. The connecting steel cable design incorporates end-connected buffer springs for vibration reduction, effectively increasing its ability to withstand impact loads and ensuring the safety and stability of the connector. All components in the connector are common in marine engineering, with proven processing and manufacturing solutions.

[0031] like Figure 1 As shown, each adjacent floating unit 1 includes a set of wave energy conversion and collection devices.

[0032] like Figure 2 As shown, the wave energy conversion and collection device consists of a liquid-filled rubber fender 4, a one-way valve 5, a relief valve 6, a rotor 7, an accumulator 8, a hydraulic motor 9, and a generator 10. The flexible buffer springs 2 are respectively located inside the two floating bodies and are connected into a whole by a flexible steel cable 3. The liquid-filled rubber fenders 4 are arranged above and below the gap between the two floating bodies, and the wave energy conversion and collection device is installed inside the floating unit 1.

[0033] The specific use process of this utility model is as follows:

[0034] After the external waves reach the multi-module floating platform unit 1, they cause the adjacent floating bodies to swing up and down and left and right, squeezing the lower liquid-filled rubber fender 4. The hydraulic oil is compressed in the liquid-filled rubber fender 4, driving the hydraulic oil to flow. After passing through the one-way valve 5, it becomes a one-way flow, passes through the relief valve 6, and then passes through the rotor 7 to drive the hydraulic motor 9, driving the generator 10 to generate electricity. The excess energy is stored in the accumulator 8. The hydraulic oil is transferred from the lower part to the upper part through the oil route for storage and standby use. The principle of squeezing the upper part is the same.

[0035] The oil circuit is equipped with a one-way valve, and the hydraulic oil can only flow in one direction. Through the periodic switching of the flow path, it is ensured that the hydraulic oil driving the hydraulic motor only flows in one direction, and the hydraulic motor will not periodically rotate forward and reverse.

[0036] The liquid-filled rubber fender 4 is elastic and naturally maintains pressure, thereby smoothing the fluctuations in hydraulic oil pressure caused by wave undulations and helping to stabilize power generation.

[0037] The utility model has a good wave energy collection effect, can effectively extract wave mechanical energy and convert it into electrical energy, and plays an important role in ensuring the life and stability of the platform's main structure and the self-sufficiency of electrical energy conversion.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
