Description

Technical Field

[0001] This invention relates to wave energy generation devices, specifically to a portable planar array rocker wave energy generation device. Background Technology

[0002] Wave energy is one of the earliest and most important renewable energy sources developed and utilized by humankind. To harness wave energy, various wave energy generation devices have been developed. However, most existing wave energy generation devices suffer from the following drawbacks: 1. Due to increased structural damping caused by gear or air chamber transmission, the secondary energy conversion rate when collecting surface waves is relatively low; 2. When fishing boat operations, sailing on unpowered vessels, and other maritime activities require sufficient electrical energy, the generation devices are bulky, inconvenient, and expensive. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problems of low secondary energy conversion rate when collecting surface waves, large size, inconvenience and high cost when fishing boat operation, sailing of non-powered sailboats and other marine activities require sufficient power energy, and to provide a portable planar array rocker wave energy generation device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A portable planar array rocker-type wave energy generation device is characterized by comprising a first float, a second float, at least one wave energy conversion component, a first battery disposed in the first float, a second battery disposed in the second float, a first power output interface connected to the first battery, and a second power output interface connected to the second battery.

[0006] The wave energy conversion assembly includes a drive shaft, a rotating plate, a first generator disposed inside a first float and connected to the first battery, and a second generator disposed inside a second float and connected to the second battery; the first generator and the second generator are connected by the drive shaft; one end of the rotating plate is disposed on the drive shaft and located between the first float and the second float, which are arranged parallel to each other, and the other end extends into the water.

[0007] Furthermore, in order to facilitate the replacement of different rotating plates according to different environmental operating conditions, one end of the rotating plate is detachably sleeved on the drive shaft; the thickness of the rotating plate gradually decreases from the end closer to the drive shaft to the end farther away from the drive shaft, which can reduce its own weight and reduce damping.

[0008] Furthermore, both the first and second pontoons are composed of a cylindrical body and hemispherical shells located at both ends of the cylindrical body;

[0009] The first power output interface is located on the side of the cylindrical body of the first buoy away from the sea level; the second power output interface is located on the side of the cylindrical body of the second buoy away from the sea level to prevent seawater from entering the power output interface.

[0010] Furthermore, it also includes two anchor chains and two waterproof covers;

[0011] One anchor chain is detachably installed on the side of the cylindrical body of the first buoy close to the sea level, and the other anchor chain is detachably installed on the side of the cylindrical body of the second buoy close to the sea level for easy fixing; one waterproof cover is installed on the outside of the first power output interface, and the other waterproof cover is installed on the outside of the second power output interface to further prevent seawater from entering the power output interface and ensure the safety of use.

[0012] Furthermore, in order to improve power generation efficiency, the wave energy conversion components consist of two units. The output shafts of the first generators in the two wave energy conversion components are parallel and arranged along the axial direction of the first buoy. The output shafts of the two second generators are parallel and arranged opposite to the two first generators. The two first generators are respectively connected to the two second generators through two drive shafts.

[0013] Furthermore, in order to reduce weight and provide corrosion resistance, both the first and second pontoons are made of PC+ABS engineering plastic alloy; the surface of the rotating plate is coated with carbon material; both the first and second batteries are lithium-ion batteries; and both the first and second generators are magnetic generators.

[0014] Meanwhile, the present invention also provides a portable planar array rocker wave energy generation device, which is special in that it includes N power generation units connected in sequence; wherein, N≥2, and N is an integer;

[0015] The power generation unit adopts the aforementioned portable planar array rocker wave energy power generation device.

[0016] Furthermore, for ease of assembly and connection, the power generation unit further includes a first connecting component and a second connecting component; the first connecting component includes M first solid connecting rods disposed at one end of the first pontoon and M first hollow connecting rods disposed at the other end of the first pontoon; the second connecting component includes P second solid connecting rods disposed at one end of the second pontoon and P second hollow connecting rods disposed at the other end of the second pontoon; wherein, M≥1, P≥1, and M and P are both integers;

[0017] M first solid connecting rods are adapted to M first hollow connecting rods at the other end of the first pontoon; the M first solid connecting rods of the first pontoon are detachably sleeved inside the M first hollow connecting rods at the other end of the first pontoon of the adjacent power generation unit.

[0018] P solid connecting rods of the second type are adapted to P hollow connecting rods of the second type at the other end of the second buoy; the P solid connecting rods of the second type are detachably fitted into the P hollow connecting rods of the second buoy at the other end of the second buoy of the adjacent power generation unit.

[0019] Furthermore, M = 2; P = 2; the connecting ends of the two first solid connecting rods and the two second hollow connecting rods face the same direction and are parallel to each other.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention provides a portable planar array rocker-type wave energy generation device, wherein the power generation unit can fully realize the power generation function. In this invention, the first generator, rotating plate, and second generator are coaxially arranged via a transmission shaft, solving the problem of low secondary energy conversion rate when collecting surface waves due to increased structural damping caused by gear transmission or air chamber transmission. Simultaneously, the coaxial design reduces manufacturing difficulty and maintenance costs, and improves service life. This invention uses rocker-type wave surge technology to convert various scattered, irregular, and highly diverse wave forms generated in nature into usable wave energy, improving the utilization efficiency of wave energy. Furthermore, this invention can be fixed to the stern of fishing boats or the edge of breakwaters, or float independently on the sea surface, meeting the needs of working in various complex environments and exhibiting stronger adaptability compared to traditional wave energy generation devices.

[0022] 2. The portable planar array rocker-type wave energy generator provided by this invention adopts a modular design concept for power generation units, which is beneficial for meeting the needs of wave energy acquisition and power generation under different sea conditions to a greater extent. Multiple power generation units are combined through the first and second connecting components to achieve modular power generation. Therefore, different numbers of power generation units can be selected for combined operation according to the required power output and power generation environment, which can better meet the needs of different occasions and power generation environments. Furthermore, the power generation units in this invention are compact, low-cost, easy to install, and portable, solving the problems of insufficient power energy and difficulty in energy collection for maritime activities such as fishing boat operations and unpowered sailboat navigation.

[0023] 3. In this invention, both the first and second pontoons are composed of a cylindrical body and hemispherical shells at both ends of the cylindrical body. Compared to a cuboid or sphere, this shape has better stability under wave impact. Furthermore, compared to a sphere, this shape has a higher aspect ratio, allowing for the installation of more rotating plates and improving energy harvesting efficiency. In addition, its elongated internal space facilitates the installation of its internal equipment, greatly reducing manufacturing complexity. The rotating plates in this invention are detachable, simplifying maintenance. Depending on different water depths and sea conditions, rotating plates of different lengths and cross-sectional areas can be replaced to maximize wave energy conversion. Additionally, the gradually decreasing thickness of the rotating plates reduces weight and damping.

[0024] 4. In this invention, both the first and second floats are made of PC+ABS engineering plastic alloy. This material possesses excellent heat and weather resistance, dimensional stability, and impact resistance, as well as excellent processing fluidity. Therefore, the first and second floats meet both performance requirements and have a simple manufacturing process. The rotating plate in this invention is coated with carbon material to achieve corrosion protection and reduce friction, resulting in good chemical stability, high temperature resistance, salt and alkali resistance, and corrosion resistance, ensuring stable operation in salt spray and seawater corrosive environments. Both the first and second batteries in this invention are lithium-ion batteries, which have high energy density, high voltage, no pollution, and long cycle life, meeting the requirements of fishing boats, industrial lighting, etc., for high capacity, long life, and rapid charge and discharge capabilities. The lithium-ion batteries can be repeatedly charged and discharged, fulfilling the pre-charging requirements of the wave energy power generation device, thereby meeting the power needs for lighting and positioning when the wave energy power generation device is placed in harsh sea conditions and low visibility environments.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] A portable planar array rocker-type wave energy generation device includes a first buoy 11, a second buoy 12, at least one wave energy conversion component 13, a first battery 14 disposed within the first buoy 11, a second battery 15 disposed within the second buoy 12, a first power output interface 16 connected to the first battery 14, a second power output interface 17 connected to the second battery 15, two anchor chains 10, and two waterproof covers. Specifically, both the first buoy 11 and the second buoy 12 are composed of a cylindrical body and hemispherical shells located at both ends of the cylindrical body. The first power output interface 16 is located on the side of the cylindrical body of the first buoy 11 away from the sea level, and the second power output interface 17 is located on the side of the cylindrical body of the second buoy 12 away from the sea level. One anchor chain 10 is detachably disposed on the side of the cylindrical body of the first buoy 11 close to the sea level, and the other anchor chain 10 is detachably disposed on the side of the cylindrical body of the second buoy 12 close to the sea level. See [reference needed] for details. Figures 1-2Due to the unpredictable waves, a waterproof cover is installed on the outside of the first power output interface 16, and another waterproof cover is installed on the outside of the second power output interface 17 to ensure the safe use of the wave energy generation device. Furthermore, both the first power output interface 16 and the second power output interface 17 are equipped with a standard household socket and a USB port. The USB port connects to an internally mounted USB charging converter, which can transform and transmit electrical energy. The standard household socket connects to a transformer and voltage regulator to ensure a stable rated voltage for electrical appliances and other equipment. The first float 11 and the second float 12 are both made of lightweight, corrosion-resistant materials such as PC+ABS engineering plastic alloy, and both the first battery 14 and the second battery 15 are lithium-ion batteries.

[0035] The wave energy conversion assembly 13 includes a drive shaft 133, a rotating plate 134, a first generator 131 disposed inside a first float 11 and connected to a first battery 14, and a second generator 132 disposed inside a second float 12 and connected to a second battery 15. The first generator 131 and the second generator 132 are connected via the drive shaft 133. One end of the rotating plate 134 is detachably mounted on the drive shaft 133. The thickness of the rotating plate 134 gradually decreases from the end closest to the drive shaft 133 towards the end furthest from the drive shaft 133, and its cross-section is approximately an inverted triangle. The other end extends into the water. The rotating plate 134 is located between the first float 11 and the second float 12, which are arranged parallel to each other. In this embodiment, there are two wave energy conversion assemblies 13. The output shafts of the two first generators 131 are parallel and arranged along the axial direction of the first float 11. The output shafts of the two second generators 132 are parallel and arranged opposite to the two first generators 131. The two first generators 131 are respectively connected to the two second generators 132 via two drive shafts 133. (See detailed reference...) Figures 1-2 Due to the detachable design of the rotating plate 134, rotating plates of different lengths and cross-sectional areas can be replaced to meet different water depths and sea conditions, maximizing wave energy conversion. Furthermore, the surface of the rotating plate 134 is coated with carbon material, and both the first generator 131 and the second generator 132 are magnetic generators.

[0036] The working principle of this portable planar array rocker-type wave energy generator in this embodiment is as follows: The power generation unit 1 is placed on the sea surface. The first float 11 and the second float 12 provide buoyancy, allowing the power generation unit 1 to float on the sea surface or be fixed to a location such as the stern of a ship, a shoal, or a dock by adjusting the length of the anchor chain 10. When there are waves on the sea surface, the waves will transmit energy, and the rotating plate 134 will be subjected to the wave force, thereby generating periodic oscillations to obtain wave energy. The amplitude of the oscillation is related to factors such as the wave height, period, and the weight of the rotating plate 134. The periodic oscillation of the rotating plate 134 will drive the first generator 131 and the second generator 132 through the drive shaft 133 to generate electricity, which is then stored in the first battery 14 and the second battery 15. External devices can be powered through the first power output interface 16 and the second power output interface 17.

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, a portable planar array rocker-type wave energy generation device includes N power generation units 1 connected in sequence, where N ≥ 2 and N is an integer; in this embodiment, N = 2. Figures 1-5 As shown, the power generation unit 1 also includes a first connecting assembly 18 and a second connecting assembly 19. The first connecting assembly 18 includes M first solid connecting rods 181 disposed at one end of the first float 11 and M first hollow connecting rods 182 disposed at the other end of the first float 11. The second connecting assembly 19 includes P second solid connecting rods 191 disposed at one end of the second float 12 and P second hollow connecting rods 192 disposed at the other end of the second float 12. M solid first connecting rods 181 are adapted to M hollow first connecting rods 182 at the other end of the first float 11. The M solid first connecting rods 181 of the first float 11 are detachably fitted into the M hollow first connecting rods 182 at the other end of the first float 11 of the adjacent power generation unit 1. P solid second connecting rods 191 are adapted to P hollow second connecting rods 192 at the other end of the second float 12. The P solid second connecting rods 191 of the second float 12 are detachably fitted into the P hollow second connecting rods 192 at the other end of the second float 12 of the adjacent power generation unit 1. In this embodiment, M=2 and P=2. The connection ends of the two solid first connecting rods 181 and the two hollow second connecting rods 192 face the same direction and are parallel to each other. It should be noted that, depending on the power demand in different environments, different numbers of power generation units 1 can be flexibly selected to be connected together for operation.

[0039] The working principle of this embodiment is the same as that of Embodiment 1.
