Description

Technical Field

[0001] The present invention relates to the technical field of marine renewable energy, and in particular to a floating wave power generation device. Background Art

[0002] With the continuous growth of global energy demand and the increasing emphasis on the development and utilization of renewable energy, wave energy, as a clean and sustainable marine energy source, has received widespread attention. Wave power generation devices convert the kinetic energy of ocean waves into electrical energy, providing a new way to solve energy shortages and reduce environmental pollution. However, existing wave power generation devices still have many shortcomings in practical applications. Traditional wave power generation devices mostly adopt fixed or semi-fixed structures, which have high installation and maintenance costs and poor adaptability to complex sea conditions. In addition, although some floating wave power generation devices can adapt to wave fluctuations to a certain extent, their energy conversion efficiency is low, the mechanical structure is complex, and they are prone to wear or failure due to long-term operation, which affects the power generation performance and service life.

[0003] Existing floating wave power generation devices typically rely on wave motion in a specific direction to drive the generator. This design makes it difficult to maintain stable power generation efficiency in the presence of fluctuating wave directions. Furthermore, the relatively simple energy transfer method between the device's internal power generation components and external wave motion results in significant energy losses, making it difficult to improve overall power generation efficiency. Furthermore, many existing devices lack adequate consideration of floating stability in their designs, making them prone to capsizing or failure in adverse sea conditions, further limiting their application.

[0004] Therefore, developing a floating wave power generation device that can efficiently utilize wave energy, adapt to multi-directional wave motion, and possesses a simple structure and strong stability has become a pressing technical challenge. This invention addresses these challenges by proposing an innovative floating wave power generation device designed to improve wave energy utilization efficiency, enhance the device's environmental adaptability, and simplify the mechanical structure to reduce maintenance costs. Summary of the Invention

[0005] This invention addresses the technical issues of existing wave power generation devices, such as complex structure, insufficient stability, and low power generation efficiency, by proposing a floating wave power generation device. By optimizing the structural design and power transmission mechanism, the device achieves the goal of efficiently utilizing wave kinetic energy for power generation.

[0006] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0007] The present invention provides a floating wave power generation device, comprising a float assembly, a generator mounting base, a universal wheel assembly, a generator assembly, and a speed-increasing gear assembly. The float assembly comprises a float sphere and a top float. The float sphere is a spherical structure with a hollow interior, designed to float on the water surface. The top float is located at the top of the float sphere, increasing the buoyancy of the upper portion of the float sphere and preventing the device from tipping over under the action of waves. Furthermore, the float sphere can be ellipsoidal or spherical in shape to accommodate different wave environments and usage requirements.

[0008] The generator mount, located in the center of the floating sphere, is hemispherical and shaped to match the inner wall of the sphere. Specifically, a gap is created between the outer surface of the generator mount and the inner wall of the sphere, allowing it to slide along the inner wall during wave motion. This design ensures the generator mount's stability under wave action and effectively transfers wave kinetic energy to the generator assembly.

[0009] Furthermore, the universal wheel assembly includes a spring connecting shaft, an end bearing, a generator bracket, and a generator connecting shaft. Specifically, the upper end of the spring connecting shaft is fixedly connected to the lower end of the generator mounting base, and the lower end is connected to the upper end of the end bearing. The lower end of the end bearing is connected to the upper end of the generator bracket, allowing the generator bracket to rotate freely. The lower end of the generator bracket is connected to the generator assembly via the generator connecting shaft, transmitting power and ensuring that the generator assembly can always rotate in a single direction. The design of the spring connecting shaft ensures that the outer ring of the friction drive wheel maintains contact with the inner wall of the floating sphere, while the end bearing provides rotational freedom for the generator bracket, thereby ensuring stable operation of the generator assembly.

[0010] The generator assembly includes a friction drive wheel outer ring, a generator lead wire, a generator drive shaft, and a generator coil. The outer wall of the friction drive wheel outer ring is a rough outer ring, which contacts the inner wall of the floating sphere and drives the generator assembly to rotate through friction. The center of the friction drive wheel outer ring is connected to the drive end of the generator coil via the generator drive shaft, transferring kinetic energy to the generator coil. The generator coil is fixed to the generator bracket and generates electricity through the rotation of the generator drive shaft. One end of the generator lead wire is connected to the power output terminal of the generator coil, and the other end is extended outside the floating sphere for transmitting electrical energy.

[0011] Specifically, the speed-increasing gear assembly includes a generator bracket and a speed-increasing drive gear. An inner ring gear is provided on the inner wall of the outer ring of the friction drive wheel, and an outer ring gear is provided in the middle of the generator drive shaft. Three speed-increasing drive gears are rotatably connected to the generator bracket, and their outer teeth mesh with the inner ring gear of the outer ring of the friction drive wheel and the outer teeth of the generator drive shaft, respectively, to achieve the speed-increasing effect. This design of the speed-increasing gear assembly significantly increases the speed of the generator coil, thereby improving power generation efficiency.

[0012] The working principle of the present invention is as follows:

[0013] S1, place the device on the sea surface or water with large waves. The floating sphere will float on the water due to its hollow structure. The presence of the float on the top ensures that the floating sphere always remains stable and will not flip over.

[0014] S2, as the waves shake, the floating sphere moves, driving the generator mounting base to slide along the inner wall of the floating sphere;

[0015] S3, the outer wall of the outer ring of the friction driving wheel contacts the inner wall of the floating sphere, and the outer ring of the friction driving wheel rotates through friction force;

[0016] S4, the rotation of the outer ring of the friction drive wheel is transmitted to the generator drive shaft through the speed-increasing gear assembly. The three speed-increasing drive gears of the speed-increasing gear assembly are respectively engaged with the inner gear ring of the outer ring of the friction drive wheel and the outer gear of the generator drive shaft to achieve the speed-increasing effect;

[0017] S5, the rotation of the generator drive shaft drives the generator coil to rotate, thereby generating electricity;

[0018] S6, the generator lead wire transmits the electrical energy to the external equipment.

[0019] The beneficial effects of the present invention are:

[0020] The design of the speed-increasing gear assembly significantly increases the speed of the generator coil, thereby improving power generation efficiency. The design of the top buoy effectively prevents the device from flipping, ensuring that the device remains stable in waves. The device can operate stably and for a long time in water environments with large waves, and is suitable for a variety of marine environments. The structure is simple, and the parts are easy to replace and maintain, reducing the cost of use. In particular, the present invention transmits kinetic energy through the friction between the outer ring of the friction drive wheel and the inner wall of the floating sphere, avoiding the complexity of traditional mechanical transmission methods. At the same time, the speed-increasing gear assembly effectively amplifies kinetic energy, further improving power generation efficiency.

[0021] In summary, the present invention provides an efficient and stable floating wave power generation device that fully utilizes the kinetic energy of waves to generate electricity and has broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0029] The present invention provides a floating wave power generation device, combined with Figures 1 to 4 As shown, the core structure of the device includes a floating assembly, a generator mounting base 2, a universal wheel assembly, a generator assembly and a speed increasing gear assembly. The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 As shown, the floating assembly consists of a floating sphere 1 and a top float 13. The floating sphere 1 is a spherical structure with a hollow interior for floating on the water. The specific shape of the floating sphere 1 can be an ellipsoidal sphere or a round sphere to adapt to different wave environments and usage requirements. The top float 13 is arranged at the top position inside the floating sphere 1. By increasing the buoyancy of the upper part, it ensures that the floating sphere 1 always remains stable under the action of waves to avoid the occurrence of overturning. A counterweight can also be set at the lower end of the floating sphere 1. The material of the floating sphere 1 is selected from lightweight and corrosion-resistant materials, such as high-strength plastics or composite materials, to ensure the durability of the device during long-term use in the marine environment.

[0031] Generator mount 2 is located in the center of floating sphere 1 and has a hemispherical structure. Its shape matches the inner wall of floating sphere 1, with a gap between its outer surface and the inner wall of floating sphere 1, allowing generator mount 2 to slide along the inner wall of floating sphere 1 during wave motion. This design not only ensures the stability of generator mount 2 under wave action, but also effectively transfers wave kinetic energy to the generator assembly. Generator mount 2 is also constructed of lightweight, high-strength materials, such as aluminum alloy or engineering plastics, to reduce overall weight and improve the device's buoyancy.

[0032] The design of the universal wheel assembly is one of the key parts of this device, and its main function is to ensure that the generator assembly can always rotate in one direction. Figure 1 and Figure 2 As shown, the universal wheel assembly includes a spring connecting shaft 3, an end bearing 4, a generator bracket 5, and a generator connecting shaft 6. The upper end of the spring connecting shaft 3 is fixedly connected to the lower end of the generator mounting base 2, while the lower end is connected to the upper end of the end bearing 4. The design of the spring connecting shaft 3 ensures that the outer ring 11 of the friction drive wheel always maintains contact with the inner wall of the floating sphere 1, thereby achieving a friction drive effect. The lower end of the end bearing 4 is connected to the upper end of the generator bracket 5, allowing the generator bracket 5 to rotate freely. The lower end of the generator bracket 5 is connected to the generator assembly via the generator connecting shaft 6, transmitting power and ensuring stable operation of the generator assembly.

[0033] The generator assembly is the core energy conversion component of this device, and its structure is as follows Figure 2 and Figure 3 As shown. The generator assembly includes a friction drive wheel outer ring 11, a generator lead wire 12, a generator drive shaft 9 and a generator coil 7. The outer wall of the friction drive wheel outer ring 11 is a rough mixed wheel outer ring. This design significantly increases the friction between the friction drive wheel outer ring 11 and the inner wall of the floating sphere 1, thereby improving the kinetic energy transfer efficiency. The middle part of the friction drive wheel outer ring 11 is connected to the driving end of the generator coil 7 through the generator drive shaft 9 to transfer kinetic energy to the generator coil 7. The generator coil 7 is fixed on the generator bracket 8 and generates electricity through the rotation of the generator drive shaft 9. One end of the generator lead wire 12 is connected to the power output end of the generator coil 7, and the other end is led out of the floating sphere 1 for transmitting electrical energy to external equipment.

[0034] The design of the speed increasing gear assembly further improves the power generation efficiency of the device. Figure 4As shown. The speed-increasing gear assembly includes a generator bracket 8 and a speed-increasing drive gear 10. An inner gear ring is provided on the inner wall of the outer ring 11 of the friction drive wheel, and an outer gear ring is provided in the middle of the generator drive shaft 9. There are three speed-increasing drive gears 10, all of which are rotatably connected to the generator bracket 8. The outer teeth of each speed-increasing drive gear 10 are respectively engaged with the inner gear ring of the outer ring 11 of the friction drive wheel and the outer teeth of the generator drive shaft 9 to achieve a speed-increasing effect. Through the design of the speed-increasing gear assembly, the rotation speed of the generator drive shaft 9 is significantly improved, thereby driving the generator coil 7 to rotate at a higher speed, further improving the power generation efficiency.

[0035] The working process of this device is as follows:

[0036] S1. Place the device on the sea or in water with large waves. Because the floating sphere 1 is hollow, the device can float on the water. The presence of the top float 13 ensures that the floating sphere 1 remains stable and will not flip due to the action of waves.

[0037] S2, as the waves shake, the floating sphere 1 moves, driving the generator mounting base 2 to slide along the inner wall of the floating sphere 1.

[0038] S3, the outer wall of the outer ring 11 of the friction driving wheel contacts the inner wall of the floating sphere 1, and the outer ring 11 of the friction driving wheel is driven to rotate by the friction force.

[0039] S4: The rotation of the outer ring 11 of the friction drive wheel is transmitted to the generator drive shaft 9 through the speed-increasing gear assembly. The three speed-increasing drive gears 10 of the speed-increasing gear assembly respectively mesh with the inner gear ring of the outer ring 11 of the friction drive wheel and the outer gear of the generator drive shaft 9 to achieve the speed-increasing effect.

[0040] S5, the rotation of the generator drive shaft 9 drives the generator coil 7 to rotate, thereby generating electricity.

[0041] S6, the generator lead wire 12 transmits the electric energy to the external device for the user to use.

[0042] Practical application scenarios of the present invention include, but are not limited to, powering marine monitoring equipment, powering offshore communication base stations, and providing electricity to remote islands. For example, in marine monitoring equipment, the device can serve as an independent power supply system, providing continuous and stable power support for the monitoring equipment. The design of the device's floating sphere 1 enables it to adapt to varying wave conditions, while the design of the top buoy 13 ensures the device's stability in harsh sea conditions. Furthermore, the device's simple structure makes component replacement and maintenance easy, reducing its cost.

[0043] To further optimize the device's performance, the present invention also includes an antifouling coating on the surface of the floating sphere 1 to reduce the impact of marine organisms on the device. Furthermore, the friction coefficient of the outer ring of the friction drive wheel 11 can be adjusted to accommodate varying wave intensities and frequencies. The elastic coefficient of the spring connecting shaft 3 can also be adjusted based on the size of the floating sphere 1 and the wave environment, ensuring that the friction drive wheel 11 maintains optimal contact with the inner wall of the floating sphere 1.

[0044] In summary, the present invention achieves the goal of efficiently utilizing wave kinetic energy for power generation by optimizing the structural design and power transmission mechanism. The design of the top float 13 effectively prevents the device from flipping over, ensuring that the device remains stable in the waves. The design of the speed-increasing gear assembly significantly increases the rotational speed of the generator coil 7, thereby improving the power generation efficiency. The device can operate stably for a long time in a water surface environment with large waves and is suitable for a variety of marine environments. The structure is simple, and the parts are easy to replace and maintain, which reduces the cost of use. In particular, the present invention transmits kinetic energy through the friction between the outer ring 11 of the friction drive wheel and the inner wall of the floating sphere 1, avoiding the complexity of traditional mechanical transmission methods. At the same time, the speed-increasing gear assembly realizes the effective amplification of kinetic energy, further improving the power generation efficiency.

[0045] As an expansion and improvement of the present invention, an electric telescopic rod can be installed between the spring connecting shaft 3 and the generator mounting seat 2. When the generated electricity is in excess and the number of generators in use needs to be reduced, the electric telescopic rod can be retracted by remote control so that the generator drive shaft does not contact the floating sphere, thereby reducing power generation and increasing the number of generators working. Secondly, a storage battery can be set in the floating sphere to store the collected electricity. The battery can be set in the generator mounting seat or in the counterweight position of the floating sphere 1. A voltage stabilizing device is also added to ensure stable and uninterrupted output of electrical energy. As an expansion, the present invention can also be configured with an intelligent monitoring module to automatically monitor the power generation situation. When the power generation is too large or too small, the number of generators put into use is automatically allocated. A wireless communication module is configured to remotely monitor and control the operation of the entire device.
