Description

Technical Field

[0001] This invention relates to the field of ocean energy power generation technology, and more particularly to an ocean energy power generation device. Background Technology

[0002] Currently, ocean energy generation technology has become a research hotspot in the energy field. Its core lies in the efficient conversion of the abundant energy contained in the ocean (such as tidal energy, wave energy, and thermal energy conversion) into clean electricity. Faced with the dual challenges of continuously growing global energy demand and the goal of carbon neutrality, it is imperative to accelerate the large-scale application and industrial development of ocean energy generation technology.

[0003] Currently, the common technology for generating ocean energy using wave energy can convert wave energy into electrical energy, but because its buoyancy mechanism and power generation device are integrated into one structure, it suffers from inconvenient transportation, small support area, and low buoyancy, resulting in unstable equipment operation.

[0004] Therefore, the present invention provides an ocean energy power generation device to solve the above-mentioned problems. Summary of the Invention

[0005] In response to the aforementioned technical problems, a marine energy power generation device is provided that can improve the device's transportation efficiency and operational stability.

[0006] The technical means employed in this invention are as follows:

[0007] A marine energy power generation device, comprising:

[0008] floating box;

[0009] The power generation unit is fixedly connected to the upper surface of the floating platform box;

[0010] At least two fixed shafts are set parallel to each other along the two opposite inner walls of the floating plate box;

[0011] A take-up section, wound on a fixed shaft and capable of switching between a take-up state and an unwinding state, the take-up section comprising:

[0012] The flexible substrate is rollable, with one end wound on a fixed shaft and the other end being a free end;

[0013] Several floating blocks are evenly inserted and fixed along the upper surface of the flexible substrate;

[0014] Flexible ribs are fixed symmetrically along the upper surface of the flexible substrate in the longitudinal direction;

[0015] The slots are symmetrically opened longitudinally along the lower surface of the flexible substrate and correspond one-to-one with the flexible ribs in the thickness direction, so that the flexible ribs are embedded in the corresponding slots when the flexible substrate is wound up.

[0016] Furthermore, the upper surface of the flexible substrate is provided with a plurality of mounting holes, and the wall of each mounting hole is provided with a radially extending mounting groove; the lower surface of the float is provided with a downwardly extending mounting block, and the outer peripheral side of the mounting block is provided with a sliding groove, and a slider and a return spring are provided in the sliding groove. The return spring elastically pushes the slider towards the mounting groove, so that the float and the flexible substrate form a detachable locking connection.

[0017] Furthermore, the outer end of the slider is provided with a pull ring, and the upper surface of the float is provided with a rope hole. One end of the pull rope is tied to the pull ring, and the other end passes through the rope hole and is fixedly connected to the pull head. Pulling the pull head drives the pull rope to drag the pull ring provided on the slider, so that the slider is pulled into the interior of the groove, so that the mounting block is released from the lock between the mounting hole and the mounting block. Then the mounting block is pulled out of the mounting hole, realizing the quick disassembly between the float and the flexible substrate.

[0018] Furthermore, the free end of the flexible substrate is provided with at least two through holes, and a support rod is inserted into the through holes; one end of the support rod is provided with a stop block, and the other end is provided with a screw rod, and a fastening nut is screwed onto the screw rod. The support rod is locked in the through holes by the clamping action of the fastening nut and the stop block, so as to maintain the unfolded state of the flexible substrate.

[0019] Furthermore, the power generation unit includes:

[0020] T-shaped plates are fixedly installed on the upper surface of the floating platform box;

[0021] The generator is fixed to the T-shaped plate;

[0022] Bushing, fixed to T-shaped plate;

[0023] The rotating part includes a flywheel and a rotating shaft fixed coaxially with the flywheel. The rotating shaft is rotatably supported by a bushing, and one end of the rotating shaft is fixedly connected to the input end of the generator.

[0024] Furthermore, a first trunnion is fixed at the eccentric position of the flywheel; a guide groove is opened on the upper surface of the float box, a buoyancy rod is slidably arranged in the guide groove, a second trunnion is fixed at the upper end of the buoyancy rod, and a float is fixed at the lower end of the buoyancy rod; the two ends of a connecting rod are respectively hinged to the first trunnion and the second trunnion, so that when the float moves up and down with the waves, it drives the flywheel to rotate through the connecting rod, thereby driving the generator to generate electricity.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The present invention provides an ocean energy power generation device, which is equipped with a winding section. The winding section can be switched to a winding state to facilitate the transportation of the device and improve the transportation efficiency of the device; when switched to an unfolded state, it increases the support area of ​​the device, increases buoyancy, and improves the stability of the device during operation.

[0027] 2. The present invention provides an ocean energy power generation device, which sets up a float and a flexible substrate. When the float needs to be inserted into the flexible substrate, it is installed by pressing down, and the float and the insertion hole of the flexible substrate are tightly fitted together. When the float needs to be removed, the pull head of the pull rope is tightened to disengage the slider inside the float, thereby achieving the purpose of quickly removing the float. This realizes the quick disassembly of the float, improves work efficiency and facilitates quick replacement.

[0028] 3. The present invention provides a marine energy power generation device, which uses a flexible substrate with symmetrical through holes at the ends to insert a support rod into the through holes. One end of the support rod is provided with a baffle, and the other end near the end of the peripheral side is provided with a threaded groove. The support rod is fixed in the through holes by tightening nuts to improve the stability of the device when operating on the sea surface.

[0029] Based on the above reasons, this invention can be widely applied in fields such as ocean energy power generation. Attached Figure Description

[0053] Example 1

[0054] Please see Figure 1-14 The present invention provides the following technical solutions:

[0055] Specifically, it refers to a marine energy power generation device, which includes a float box 1; a power generation unit 2 is fixedly connected to the surface of the float box 1; a fixed shaft 3 is fixed between each inner wall of the float box 1; and a winding part 4 is wound on the fixed shaft 3.

[0056] The winding section 4 includes a flexible substrate 5; the flexible substrate 5 is wound on a fixed shaft 3; flexible ribs 7 are symmetrically fixedly connected to the surface of the flexible substrate 5; slots 8 are symmetrically opened on the bottom surface of the flexible substrate 5; the flexible ribs 7 are inserted into and connected to the slots 8; a number of floating blocks 11 are evenly inserted into the surface of the flexible substrate 5.

[0057] The specific application of this embodiment is as follows:

[0058] When the flexible substrate 5 is wound up, the flexible ribs 7 of the flexible substrate 5 engage with the slots 8 during the winding process to prevent the flexible substrate 5 from deviating during the winding process, thereby improving the winding quality of the flexible substrate 5.

[0059] Meanwhile, a cavity is formed between the flexible rib 7 and the slot 8 to house the floating block 11 that is inserted and mated with the flexible substrate 5, reducing the floor space occupied during transportation and improving the transportation efficiency of the device.

[0060] Example 2

[0061] Please see Figure 1-14 This embodiment 2 is an improvement on the first embodiment as follows: Specifically, a plurality of mounting holes 9 are uniformly opened on the surface of the flexible substrate 5; mounting grooves 10 are opened on the inner wall of the mounting holes 9; a mounting block 12 is fixedly arranged on the bottom surface of the float 11; the mounting block 12 is inserted and engaged with the mounting holes 9.

[0062] A groove 13 is provided on the outer periphery of the mounting block 12; a slider 14 is slidably disposed inside the groove 13; a return spring 15 is connected to the bottom of the slider 14 and the groove 13. A pull ring 16 is fixedly connected to the surface of the slider 14; a rope hole 18 is provided on the top surface of the float 11; a pull rope 19 is fixedly connected to the rope hole 18 and the pull ring 16; the pull rope 19 passes through the rope hole 18; a pull head 20 is fixed to the other end of the pull rope 19.

[0063] The flexible substrate 5 has symmetrical through holes 6 at its ends; a support rod 21 is inserted into the through hole 6; a stop block 22 is fixed to one end of the support rod 21; a screw 23 is fixed to the other end of the support rod 21; and a fastening nut is screwed onto the screw 23.

[0064] The specific implementation method of this embodiment is as follows: When the winding section 4 needs to be unfolded and laid out, the flexible substrate 5 wound on the fixed shaft is unfolded, the support rod 21 is inserted into the through hole 6, and the screw 23 is screwed with a fastening nut to fix the support rod 21 on the flexible substrate 5, so that the flexible substrate 5 maintains a stable horizontal state, thereby improving the stability of the flexible substrate 5.

[0065] During the installation of the float 11 and the flexible substrate 5, the float 11 is pressed down along the mounting hole 9. The inclined surface of the sliding slider 14 is guided and squeezed by the mounting hole 9, causing the slider 14 to slide into the groove 13. The return spring 15 is compressed. When the slider 14 is aligned with the mounting groove 10, the elastic return force of the return spring 15 drives the slider 14 to insert into the mounting groove 10, thus completing the installation of the float 11 and the flexible substrate 5.

[0066] To disassemble the float 11, the pull head 20 is pulled, causing the pull rope 19 to drag the pull ring 16 on the slider 14, pulling the slider 14 into the groove 13. This disengages the mounting block 12 from the mounting hole 9, allowing the mounting block 12 to be pulled out of the mounting hole 9, thus achieving quick disassembly of the float 11 from the flexible substrate 5. This embodiment enables rapid installation and disassembly of the float 11 from the flexible substrate 5, improving work efficiency.

[0070] The specific implementation of this embodiment is as follows: When the device is placed on the sea surface, the buoy 17 floats up and down with the movement of the waves, causing the buoyancy rod 32 and the second lug 33 fixedly installed on the buoyancy rod 32 to move up and down together. During this process, the second lug 33 drives the connecting rod 34, causing the first lug 30 connected to the other end of the connecting rod 34 to follow the movement, thereby driving the flywheel 28 to rotate. A rotating shaft 29 is provided on the other side of the flywheel 28, which rotates together with the flywheel 28. The rotation of the rotating shaft 29 drives the generator 25 to generate electricity, thereby realizing the technology of generating electricity through ocean energy.

[0071] The core structure of the power generation unit 2 in the prior art includes a float (equivalent to a buoy 17), a mechanical transmission system (equivalent to a rotating part 27), and a generator 25. The function of the float is to generate linear motion with the wave motion, providing power to the power generation device; the function of the mechanical transmission system is to convert the motion of the float into mechanical energy; and the function of the generator is to use the mechanical transmission device to drive the generator to rotate and generate electricity.
