[0002] Most existing offshore platforms use conversion devices (hydraulic or pneumatic) to capture unidirectional wave energy. Therefore, when designing an offshore energy platform, it is necessary to consider the adaptability of the offshore platform to energy direction and energy flow density.

[0003] However, the marine environment is complex and wave energy is highly seasonal. Not only does the energy flux density change with the seasons, but the direction of energy also changes with the seasons, resulting in a decrease in the efficiency of wave energy capture by the designed offshore platforms, which is not conducive to the normal operation of the offshore platforms. Summary of the invention

[0004] In view of the above problems, the present invention proposes a multi-energy power supply platform with omnidirectional energy acquisition, which can achieve omnidirectional energy acquisition, is not affected by the direction of energy, and can adapt to different seasons and different sea areas and marine environments.

[0012] In some embodiments, the wave-facing surface of the wave-absorbing float is bent and extended outwardly upward in a direction away from the main floating body, and the back wave surface of the wave-absorbing float is set as a vertical surface.

[0013] In some embodiments, the middle portion of the piston rod is fixed to the circumferential side of the upper end surface of the main floating body through a guide rail, so that the movement trajectory of the piston rod is constrained to a preset direction.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the content of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all the contents.

[0025] This embodiment proposes a multi-energy power supply platform for omnidirectional energy acquisition, such as Figure 1 , 2 and 3, including:

[0026] A main floating body 1, with an anchoring mechanism installed at the bottom;

[0027] A plurality of wave-absorbing floats 2 are circumferentially distributed on a certain horizontal plane above the main float 1;

[0028] The hydraulic cylinders 3 are circumferentially distributed around the main floating body 1, and the number thereof matches the wave-absorbing floats 2;

[0029] A piston rod 4, one end of which is fixedly connected to the back wave surface of the corresponding wave absorbing float 2, and the other end of which is connected to the corresponding hydraulic cylinder 3;

[0030] The wave-absorbing float 2 includes a first float 201 and a second float 202 with different wave-absorbing areas, and the first float 201 and the second float 202 are arranged at an interval.

[0031] In this embodiment, by setting a plurality of wave-absorbing floats 2 distributed along the circumference on the circumference of the main floating body 1, the device can receive omnidirectional waves, wherein the wave-absorbing float 2 includes a first float 201 and a second float 202 with different wave-absorbing areas, which can adapt to different sea conditions and optimize energy conversion efficiency. When the incoming waves push the wave-absorbing float 2 to move up and down, the main floating body 1 and the cylinder barrel of the hydraulic cylinder 3 thereon are fixed by the anchoring mechanism. At this time, the wave-absorbing float 2 drives the piston rod 4 to reciprocate in and out of the cylinder barrel of the hydraulic cylinder 3, sucking in low-pressure hydraulic oil and squeezing out high-pressure hydraulic oil, converting wave energy into hydraulic energy, and then converting the hydraulic energy into electrical energy or other forms of energy through equipment such as hydraulic motors.

[0032] In this solution, the size and shape of the wave absorbing float 2 can be flexibly changed. In one example, Figure 3 As shown, the wave-facing surface of the wave-absorbing float 2 is bent outwardly in the direction away from the main floating body 1, and the back wave surface of the wave-absorbing float 2 is set as a vertical surface. The wave-facing surface of the wave-absorbing float 2 is set to bend outward to absorb the vertical component of the wave force upward, and the back wave surface is set as a vertical surface to cooperate with the piston rod 4 to initially constrain the motion trajectory of the piston rod 4 in the vertical direction. More preferably, the middle part of the piston rod 4 is fixed to the peripheral side of the upper end surface of the main floating body 1 through the guide rail 5, and the motion trajectory of the piston rod 4 is further constrained in a preset direction (such as the vertical direction) to protect the hydraulic cylinder 3.

[0033] As another important embodiment of the present invention, Figure 2As shown, the main floating body 1 includes a coaxially arranged vertical cabin 101 and a horizontal cabin 102. The horizontal cabin 102 is installed at the bottom of the vertical cabin 101, and the diameter of the horizontal cabin 102 is larger than the diameter of the vertical cabin 101. When the platform is towed to the designated sea area, water is filled into the horizontal cabin 102, the entire main floating body 1 is adjusted to the designed floating state, and the anchoring mechanism is deployed. The anchoring mechanism includes an anchor chain 9 installed at the bottom end of the horizontal cabin 102, and an anchor block 10 connected to the anchor chain 9. In addition, the horizontal tank 102 also undertakes the force balancing task of the main floating body 1. When the wave crest passes, due to the wave force, the entire main floating body 1 tends to move upward. Since the upper end surface of the vertical tank 101 is exposed to the sea surface, and the upper end surface of the horizontal tank 102 is located below the sea surface, after the horizontal tank 102 pushes the water above the upper end surface area upward, the water body will give the horizontal tank 102 a downward reaction force. The horizontal tank 102 will be subjected to the downward force from the water body and transmitted to the vertical tank 101. The upward wave force is balanced with the downward water body damping force, and the main floating body 1 is finally manifested as remaining in its original position. Then, the piston rod 4 is driven by the wave absorbing float 2 and moves upward along the guide rail 5 to enter the hydraulic cylinder 3, the pressure in the cylinder increases, and the low-pressure hydraulic oil is pumped out.

[0034] Also include a number of buoyancy chambers 6, such as Figure 1 As shown, the buoyancy tanks 6 are circumferentially distributed around the vertical tank 101 via the horizontally arranged fixing rods 7, and each buoyancy tank 6 is arranged between two adjacent wave-absorbing floats 2 to ensure that the posture of the main floating body 1 remains relatively vertical. Specifically, the highest point of the buoyancy tank 6 is flush with the highest point of the vertical tank 101, and the bottom of the buoyancy tank 6 is against the upper end surface of the horizontal tank 102.

[0035] Continue reading Figure 2 , and also includes a damping plate 8, which is installed on the outer periphery of the vertical cabin 101 and is annular, and the damping plate 8 is located below the wave-absorbing buoy 2. The function of the damping plate 8 is similar to that of the horizontal cabin 102. As an auxiliary device of the horizontal cabin 102, it undertakes the force balance task of the main floating body 1. When the wave crest passes, due to the action of the wave force, the damping plate 8 also has a tendency to move upward. Since the damping plate 8 is located below the sea surface, after the damping plate 8 pushes the water above the upper end surface area upward, the water body will give the damping plate 8 a downward reaction force. The damping plate 8 will be subjected to the downward force from the water body and transmitted to the vertical cabin 101. The upward wave force is balanced with the downward water damping force, and finally the main floating body 1 remains in its original position.

Any equivalent changes or modifications made based on the essence of the content of the present invention should be included in the protection scope of the present invention.
