Wave power generation technology converts the mechanical energy of waves into electrical energy, providing a potential energy supply way for islands, coastal cities, and ocean-going ships, etc.

[0003] Traditional wave power generation devices mostly adopt structures such as floating type or oscillating float type, and drive generators to generate electricity through the up and down floating or swinging of waves. However, these devices often have problems such as low power generation efficiency, complex structure, high maintenance cost, and mostly adopt a single floating body structure, which limits their large-scale commercial application. Summary of the Invention

[0004] In order to overcome the deficiencies of existing wave power generation devices and improve the utilization efficiency of wave energy, the present invention proposes a floating block matrix type wave power generation device, aiming to effectively capture and efficiently convert wave energy through a floating block structure arranged in a matrix, combined with an efficient transmission mechanism and a power generation mechanism.

[0005] To achieve the above invention purpose, the present invention adopts the following technical solutions: A floating block matrix type wave power generation device includes: A frame body, floating blocks, a transmission mechanism, and a power generation mechanism; The frame body is a three-dimensional rectangular frame structure, fixedly arranged in the sea surface and underwater area; The floating blocks are multiple rectangular suspension medium blocks, horizontally arranged in the middle of the upper layer of the frame body, and rotate in a door leaf manner as the waves rise and fall; The transmission mechanism connects the floating blocks and the power generation mechanism, and transmits the mechanical energy of the floating blocks to the power generation mechanism; The power generation mechanism is fixed at one end of the middle layer of the frame body and is driven to generate electricity through the transmission mechanism.

[0006] Preferably, the frame body includes: Main beam structure: composed of a first main beam and a second main beam in the upper layer and a third main beam and a fourth main beam in the lower layer, and vertically connected by multiple supports; Shaft assembly: the inner shaft rod longitudinally penetrates the floating blocks and extends at both ends, and the outer shaft rod is locked by two locking devices at the bottom of the floating blocks; Motor box: An enclosed box is provided at the middle of one end of the third main beam and the fourth main beam.

[0007] Preferably, the transmission mechanism includes: Gear set: The first gear is fixed to the middle of the outer shaft rod and is fixedly locked with the arc gear; the second gear is fixed to the middle of the rotating shaft and meshes with the arc gear unidirectionally, and the third gear and the fourth gear are arranged on both sides thereof; Drive belt: The first drive belt connects the third gear and the power generation mechanism, and the second drive belt connects the fourth gear and the power generation mechanism; Bearing: A plurality of bearings support the rotating shaft inside the support.

[0008] Preferably, the arc gear is a one-way tooth structure, which only drives the second gear to rotate when the floating block rises and disengages when it descends.

[0009] Preferably, the power generation mechanism includes: Generator: It is arranged inside the motor box; Transmission assembly: The first straight shaft and the second straight shaft are respectively connected to the generator rotor, and the fifth gear and the sixth gear are fixed at the ends, and are linked with the transmission mechanism through the drive belt.

[0010] Preferably, the floating blocks can be stacked in multiple groups in the horizontal closed state, which is convenient for transportation; the device supports single-group independent power generation or modular assembly into a matrix-type combined power generation system.

[0011] Preferably, the drive belt is made of a seawater corrosion-resistant material, and the gear set and the bearing are designed with waterproof seals.

[0012] Compared with the prior art, the present invention has the following beneficial effects: A floating block matrix-type wave power generation device of the present invention adopts a frame body with a three-dimensional rectangular frame structure, and arranges a plurality of rectangular floating blocks horizontally in the middle of the upper layer of the frame body. The floating blocks can rotate in a door leaf manner as the waves rise and fall. Through a specific transmission mechanism, the mechanical energy of the floating blocks is transmitted to the power generation mechanism, thereby driving the generator to generate electricity. In addition, the device of the present invention can be stacked, which is convenient for transportation and modular assembly, providing the possibility for constructing a matrix-type combined power generation system.

[0013] The present invention utilizes the synergistic effect of the matrix-type floating blocks, enabling the device to fully capture the energy of different wave phases. Compared with the traditional single floating body power generation device, the energy conversion efficiency is higher. In addition, the multi-stage gear transmission mechanism of the present invention can achieve energy transmission in both the forward and reverse directions of the floating block swing, reducing the energy waste caused by traditional one-way transmission, thereby improving the stability of the power generation system.

It can be used alone or assembled in parallel to form a large-scale power generation matrix, and is suitable for power supply in ocean ranches, offshore platforms and coastal cities. Moreover, the power generation mechanism adopts a closed waterproof structure, and is combined with corrosion-resistant materials and protective coatings, effectively improving the durability of the device and its resistance to the marine environment, reducing maintenance costs and extending the service life of the equipment.

[0015] In addition, the present invention optimizes the connection method of the floating blocks for complex ocean wave conditions, can adapt to different sea conditions, and ensures that the system can still operate stably even in bad weather, avoiding the risk of damage to traditional wave power generation equipment due to excessive single-point stress. Generally speaking, the present invention is superior to the prior art in terms of power generation efficiency, stability, adaptability and durability, providing a more reliable solution for the utilization of marine clean energy.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices or methods consistent with some aspects of the present application detailed in the appended claims. Embodiment 1: Frame Structure and Component Connection

[0024] The floating block matrix type ocean wave power generation device of the present invention adopts a frame with a three-dimensional rectangular frame structure, as Figure 2 , Figure 3 shown. The frame 1 is mainly composed of a first main beam 11, a second main beam 12, a third main beam 13, a fourth main beam 14 and a plurality of supports 15. Each main beam is a hollow rectangular tube and is perpendicularly connected to the plurality of equally spaced supports 15 to form a stable frame structure, and the connection method is welding or riveting; wherein the first main beam 11 and the second main beam 12 are located in the upper layer of the frame 1 and are arranged in parallel; the third main beam 13 and the fourth main beam 14 are located in the lower layer of the frame 1 and are arranged in parallel. The support 15 is made of the same material as each main beam, which is a hollow rectangular short tube, and is used to enhance the overall strength and indirectly provide installation support for the floating block 2 and the transmission mechanism 3.

[0025] The frame 1 is fixedly arranged in the sea surface and underwater area, and can be fixed by an anchoring system or an offshore platform fixing device such as an underwater pillar, a buoy anchoring, etc., to ensure the stability of the device during operation at sea; the surface of the frame 1 is provided with an anti-corrosion coating and plugs are provided at the pipe orifices of all the frames 1.

[0026] The design of the frame 1 supports modular assembly, and can be assembled according to actual needs and expanded into a large-scale matrix type combined power generation system. Embodiment 2: Connection Method and Swing of Floating Blocks

[0027] It can be understood that the floating block 2 is a plurality of rectangular suspended medium blocks, made of high-strength and corrosion-resistant materials, preferably polyethylene or composite materials, and is fixed to the middle of the upper layer of the frame through a shaft assembly. Through Figure 2-3It can be seen that the shaft assembly is an important part of the frame body 1, which includes an inner shaft rod 16, an outer shaft rod 18 and a pipe locking device 17; the inner shaft rod 16 longitudinally penetrates through the floating block 2 and extends at both ends. The inner shaft rod 16 is rotationally connected to the upper layer of the first main beam 11 and the second main beam 12 of the frame body. Preferably, a rotating bearing 36 is arranged at the rotational connection. The inner shaft rod 16 is a thick-walled hollow pipe and is fixedly connected to the floating block 2. The floating block 2 can stably rotate on the shaft rod 16; the outer shaft rod 18 is a hollow thin-walled pipe and is arranged at the bottom of the floating block 2. Both ends of the outer shaft rod 18 are installed in two pipe locking devices 17. The pipe locking device 17 can realize the convenient locking of the outer shaft rod 18. The outer shaft rod 18 is fixedly connected to the floating block 2 to form an integral body, so that the floating block 2 can swing in a door leaf manner when affected by sea waves and transmit kinetic energy to the transmission mechanism 3. Embodiment 3: Connection and power transmission of the transmission mechanism

[0028] The transmission mechanism 3 includes components such as a gear set, a transmission belt and bearings, and is used to convert the swing of the floating block 2 into stable mechanical energy and transmit it to the power generation mechanism 4; its core components include: Connection method of the gear set 1. The first gear 31 is fixed in the middle of the outer shaft rod 18 and is fixedly locked with the arc gear 35; 2. The second gear 32 is installed in the middle of the rotating shaft 37 and is in one-way meshing with the arc gear 35, so that when the floating block 2 rises, it can drive the rotating shaft 37 to rotate, and when it descends, it disengages from the meshing, so as to improve the energy conversion efficiency; 3. The third gear 33 and the fourth gear 34 are respectively arranged at both ends of the rotating shaft 37 for further power transmission.

[0029] Specifically, as Figure 4 shown, the gear set includes a first gear 31, a second gear 32, a third gear 33, a fourth gear 34 and an arc gear 35. The first gear 31 is fixed on the outer shaft rod 18 and is fixedly locked with the arc gear 35; when the floating block 2 rises, the first gear 31 and the arc gear 35 rotate within a certain locking angle; since the arc gear 35 is a one-way tooth structure, it only meshes with the second gear 32 when the floating block 2 rises and disengages when it descends. This design ensures that the transmission mechanism 3 will not be affected by the reverse torque when the floating block 2 descends, thereby improving the stability and efficiency of the entire device.

[0030] The second gear 32 is fixed to the middle of the rotating shaft 37, and the third gear 33 and the fourth gear 34 are respectively arranged on both sides. When the arc gear 35 drives the second gear 32 to rotate, the second gear 32 drives the third gear 33 and the fourth gear 34 to rotate respectively. This design realizes the distribution and balanced transmission of power, providing a necessary power source for the subsequent power generation process.

[0031] Drive belt and power transmission According to Figure 4 It can be known that the drive belt includes a first drive belt 38 and a second drive belt 39. The first drive belt 38 connects the third gear 33 with the transmission component in the power generation mechanism 4, and transmits power to the rotor of the generator 41. The second drive belt 39 connects the fourth gear 34 with another transmission component in the power generation mechanism 4, and also transmits power to the rotor of the generator 41. Multistage transmission ensures stable and efficient energy conversion. This design realizes the linkage between multiple gear sets inside the drive belt, continuously provides kinetic energy through the action of sea waves, ensures the balanced distribution and efficient transmission of power, and improves the efficiency and stability of the entire power generation process.

[0032] The bearing 36 is one of the important components in the transmission mechanism 3, responsible for supporting the inner shaft rod 16 and the rotating shaft 37 to play a role in rotation and reducing friction and wear. In the present invention, a plurality of the bearings 36 are installed in the support 15 for supporting the rotating shaft 37 and enabling it to rotate smoothly; the bearing 36 is provided with sealing measures or anti-corrosion and acid and alkali resistant process treatments to ensure its good wear resistance, corrosion resistance and stability.

[0033] Through the setting of the above components, it is ensured that the transmission mechanism 3 can efficiently convert the mechanical energy of the floating block into stable rotational oscillation and transmit it to the power generation mechanism 4 to realize the efficient utilization of wave energy. Embodiment 4: Connection and working principle of the power generation mechanism

[0034] The power generation mechanism 4 is mainly composed of the generator 41 and a transmission component, and is installed at one end of the middle layer of the frame body 1 and connected to the transmission mechanism 3. Its specific structure and connection method are as follows: The generator 41 is one of the core components of the power generation mechanism 4, responsible for converting mechanical energy into electrical energy. In the present invention, the generator 41 is fixed inside the motor box 19 to prevent seawater erosion and mechanical damage; the generator 41 is connected to the transmission mechanism 3 through a transmission component; the type selection and parameter design of the generator 41 need to be determined according to actual requirements to ensure that it can efficiently convert mechanical energy into electrical energy.

[0035] According to Figure 5It is understandable that the motor box 19 is a welded and sealed structure, designed in a closed manner, and provided with three layers of anti-corrosion coatings. The motor box 19 is fixedly connected to the third main beam 13 and the fourth main beam 14, and shock-absorbing rubber pads are arranged inside the box to effectively buffer the impact of sea waves.

[0036] It is known from Figure 4 that the transmission assembly includes a first straight shaft 42, a fifth gear 43, a second straight shaft 44 and a sixth gear 45. The first straight shaft 42 and the second straight shaft 44 are respectively connected to the rotor of the generator 41 and are supported in the motor box 19 by setting components such as bearings. The fifth gear 43 and the sixth gear 45 are respectively fixed at the ends of the first straight shaft 42 and the second straight shaft 44, and are connected to the gears in the transmission mechanism 3 through the transmission belt 38 and the transmission belt 39. When the transmission mechanism 3 transmits power to the gear set, the gear set drives the fifth gear 43 and the sixth gear 45 to rotate, thereby driving the rotor of the generator 41 to rotate and generate electric energy.

[0037] The generator 41 transmits the generated electric energy to the shore or energy storage equipment through cables, which can be used for power supply of offshore facilities, coastal city power grids or ocean-going ships. Embodiment 5: Power generation method of modular transportation and modular assembly

[0038] Modular assembly and transportation According to Figure 5 it can be understood that the floating block matrix type wave power generation device of the present invention also has the characteristics of modular assembly and convenient transportation; the floating blocks 2 can be stacked in multiple groups in the horizontal closed state, which can not only reduce the transportation volume and cost, but also improve the transportation efficiency. Through Figure 1 and Figure 2 as shown, users can choose single-group independent power generation or modular assembly into a matrix type combined power generation system according to actual needs. This design makes the device of the present invention more flexible and practical; the specific implementation method is as follows: Single-group independent power generation 1. A single frame 1 is used as an independent power generation unit, which is suitable for small energy demands, such as power supply for offshore buoys; 2. The internal components of each independent unit, including floating blocks, transmission mechanisms, and power generation mechanisms, are all designed in a standardized manner, and the layout can be flexibly adjusted to adapt to different wave environments.

[0039] Matrix type combined power generation system 1. Multiple frames 1 are connected side by side and fixed by using a standardized connection structure, preferably a bracket splicing or locking interface; 2. In the matrix structure, multiple independent units cooperate to jointly drive multiple power generation mechanisms, forming a large-scale ocean power generation system, which is suitable for island power supply or offshore platform applications; Since each unit module is independent, even if a certain unit shuts down due to maintenance or failure, the overall system can still maintain the power generation capacity, improving the reliability. Example 6: Anti-corrosion measures and environmental adaptability

[0040] Due to the characteristics of the marine environment such as high humidity and high salinity, in order to improve the durability of the device, the present invention takes the following anti-corrosion measures: Material anti-corrosion design The frame 1 is made of corrosion-resistant alloy material or high-strength composite material and is treated with an anti-rust coating to extend its service life; The floating block 2 is made of seawater-resistant polyethylene or composite material, and is filled with waterproof foam inside to ensure long-term stable buoyancy; Components such as the gear sets 31-35 and the bearings 36 in the transmission mechanism 3 are made of stainless steel or titanium alloy materials, and are prevented from being eroded by seawater by means of a sealing structure or painting coverage.

[0041] All metal components are subjected to triple anti-corrosion treatment: 1. Hot-dip galvanized layer, thickness ≥ 95μm; 2. Epoxy coal tar pitch coating, dry film thickness 350μm; 3. Polyurethane topcoat, salt spray resistance test ≥ 5000h.

[0042] Sealing and protection The generator 41 is encapsulated in the motor box 19, and a waterproof ventilation system can also be equipped to ensure the normal operation of the internal equipment in the marine environment; The transmission belts 38 and 39 are made of seawater-resistant materials, and a protective cover can also be equipped to prevent seawater scouring and marine organism attachment.

[0043] The specific embodiments of the present invention have been described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
