Detailed Description
The present invention will be described in further detail with reference to the drawings and the detailed description below, in order to make the objects, technical solutions and advantages of the present invention more clear and distinct. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the matters related to the present invention are shown in the accompanying drawings.
The embodiment provides an omnidirectional energy-obtaining multi-energy power supply platform, as shown in fig. 1, 2 and 3, including:
the bottom of the main floating body 1 is provided with an anchoring mechanism;
A plurality of wave-absorbing floats 2, the circumferences of which are distributed on a certain horizontal plane at the upper part of the main floating body 1;
The hydraulic cylinders 3 are circumferentially distributed on the periphery of the main floating body 1, and the number of the hydraulic cylinders is matched with that of the wave-absorbing floats 2;
One end of the piston rod 4 is fixedly connected with the back wave surface of the corresponding wave-absorbing floater 2, and the other end of the piston rod is connected with the corresponding hydraulic cylinder 3;
Wherein the wave-absorbing float 2 comprises 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 intervals.
In this embodiment, by arranging a plurality of wave-absorbing floats 2 circumferentially distributed on the circumferential side of the main floating body 1, the device can receive omnidirectional waves, wherein the wave-absorbing floats 2 comprise 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 wave-absorbing float 2 is driven to reciprocate up and down by the incoming waves, the main float 1 and the cylinder barrel of the hydraulic cylinder 3 on the main float are fixed by the anchoring mechanism, at the moment, the wave-absorbing float 2 drives the piston rod 4 to reciprocate in and out of the cylinder barrel of the hydraulic cylinder 3, low-pressure hydraulic oil is sucked, high-pressure hydraulic oil is extruded, wave energy is converted into hydraulic energy, and then the hydraulic energy is converted into electric energy or other forms of energy through equipment such as a hydraulic motor.
In this scheme, the size and shape of the wave-absorbing float 2 can be flexibly changed, in one example, as shown in fig. 3, the wave-facing surface of the wave-absorbing float 2 bends and stretches outwards along the obliquely upper direction away from the main float 1, the back wave surface of the wave-absorbing float 2 is set to be a vertical surface, the wave-facing surface of the wave-absorbing float 2 is set to be bent outwards and used for absorbing upward vertical components of wave force, and the back wave surface is set to be a vertical surface and then used for being matched with the piston rod 4, so that the motion track of the piston rod 4 is primarily restrained in the vertical direction. Preferably, the middle part of the piston rod 4 is fixed on the circumference of the upper end surface of the main floating body 1 through a guide rail 5, so that the motion track of the piston rod 4 is further restrained in a preset direction (such as a vertical direction), and the hydraulic cylinder 3 is protected.
As still another important embodiment of the present invention, as shown in fig. 2, the main floating body 1 includes a vertical tank 101 and a horizontal tank 102 coaxially disposed, the horizontal tank 102 is installed at the bottom of the vertical tank 101, and the horizontal tank 102 has a diameter larger than that of the vertical tank 101, when the platform is towed to a designated sea area, water is filled into the horizontal tank 102, the entire main floating body 1 is adjusted to a designed floating state, an anchoring mechanism is deployed, and the anchoring mechanism includes an anchor chain 9 installed at the bottom end of the horizontal tank 102, and an anchor block 10 connected to the anchor chain 9. In addition, the horizontal cabin 102 also bears the force balance task of the main floating body 1, when the wave crest passes, the whole main floating body 1 has a trend of upward movement due to the action of wave force, the upper end face of the vertical cabin 101 is exposed out of the sea surface, and the upper end face of the horizontal cabin 102 is positioned below the sea surface, so that after the horizontal cabin 102 pushes the water body above the area of the upper end face upwards, the water body can give the horizontal cabin 102 a downward reaction force, the horizontal cabin 102 is transmitted to the vertical cabin 101 by the downward force from the water body, the upward wave force is balanced with the downward water body damping force, and finally the main floating body 1 is kept in the original position. Then, the piston rod 4 is driven by the wave-absorbing float 2, moves upward along the guide rail 5 into the hydraulic cylinder 3, increases in cylinder pressure, and pumps out low-pressure hydraulic oil.
The buoyancy tanks 6 are circumferentially distributed on the circumferential side of the vertical tank 101 through horizontally arranged fixing rods 7, as shown in fig. 1, and each buoyancy tank 6 is arranged between two adjacent wave-absorbing floats 2 and is used for ensuring that the posture of the main floating body 1 is kept relatively vertical. Specifically, the highest point of the buoyancy chamber 6 is flush with the highest point of the vertical chamber 101, and the bottom of the buoyancy chamber 6 abuts against the upper end surface of the horizontal chamber 102.
With continued reference to fig. 2, the vertical floating body further comprises a damping plate 8, the damping plate 8 is installed on the periphery of the vertical cabin 101 and is annular, the damping plate 8 is located below the wave-absorbing floater 2, the damping plate 8 acts like a horizontal cabin 102 and serves as an auxiliary device of the horizontal cabin 102 to bear the force balance task of the main floating body 1, when a wave crest passes, the damping plate 8 also has the upward movement trend due to the action of wave force, and the damping plate 8 is located below the sea surface, so that after the damping plate 8 pushes the water body above the upper end surface area upwards, the water body can give downward reaction force to the damping plate 8, the damping plate 8 is subjected to downward force from the water body to be conducted to the vertical cabin 101, the upward wave force is balanced with the downward water body damping force, and finally the main floating body 1 is kept in the original position.
