Description

Technical Field

[0001] The present invention relates to the technical field of ocean wave power generation, in particular to a device for generating electricity by driving ocean wave fluctuations. Background Art

[0002] As the global demand for renewable energy continues to increase, wave energy, as a rich form of energy, has received increasing attention for its development and utilization technology. Existing wave power generation devices still have certain limitations in terms of structural design, energy efficiency conversion, and cost control. For example, some devices have low efficiency in capturing wave kinetic energy, or the equipment manufacturing and maintenance costs are high, which affects the large-scale promotion and application of wave power generation technology.

[0003] As an important branch of ocean energy utilization, wave power generation technology has made significant progress in recent years. Scientific research institutions and enterprises in various countries have invested a lot of resources to develop various types of wave power generation devices, aiming to effectively convert the kinetic energy and potential energy of waves into electrical energy, providing clean and sustainable energy for mankind. At present, common types of wave power generation devices include oscillating water column type, float type, point absorption type, pendulum type, etc. Each type has its own unique structure and working principle. For example, the oscillating water column device uses waves to make the water column oscillate up and down in the air chamber, thereby promoting air flow to drive the turbine to generate electricity; the float type device relies on the float to move with the waves, and drives the generator through mechanical transmission or hydraulic system.

[0004] However, despite these technological advances, existing wave power generation devices still face many challenges and limitations. In terms of structural design, many devices have complex structures and numerous components, which makes the manufacturing and assembly process cumbersome, increasing production costs and time. At the same time, the complex structure also means that failures are more likely to occur in the harsh marine environment, increasing the difficulty and frequency of maintenance. For example, some devices contain a large number of mechanical transmission components, such as gears, connecting rods, etc., which are prone to wear and damage under the long-term impact of waves and the corrosive marine environment. In addition, the structural stability of some devices is insufficient, and they cannot effectively cope with the impact of waves under different sea conditions and meteorological conditions, limiting their application in a wider range of sea areas.

[0005] In terms of energy efficiency conversion, the energy efficiency conversion efficiency of existing wave power generation devices generally needs to be improved. Due to the irregularity and randomness of waves, there is a problem of large energy loss in the process of capturing wave kinetic energy and converting it into electrical energy. For example, in the process of converting mechanical energy into electrical energy, some devices cannot fully utilize the input mechanical energy due to the design and performance limitations of the generator, resulting in low power generation efficiency. At the same time, some devices have poor adaptability to waves of different frequencies and amplitudes, and cannot efficiently capture and convert wave energy under various sea conditions, thus affecting the overall power generation performance.

[0006] In terms of cost control, the high manufacturing and maintenance costs of wave power generation devices are one of the key factors restricting their large-scale promotion. In terms of manufacturing costs, some devices use high-strength, corrosion-resistant special materials, such as high-performance alloys and composite materials. These materials are expensive and difficult to process, which further pushes up the manufacturing costs. In addition, complex manufacturing processes and precision parts processing also increase production costs. In terms of maintenance costs, due to the harshness of the marine environment, the device is susceptible to seawater corrosion, biological attachment, mechanical wear and other problems during long-term operation, and requires frequent maintenance and repairs. For example, it is necessary to regularly clean the marine biological attachments on the surface of the device, replace damaged parts, and maintain and inspect key parts, all of which increase the maintenance workload and costs. The high manufacturing and maintenance costs put wave power generation technology at a disadvantage in the competition with other renewable energy technologies, limiting its share and application scope in the global energy market.

[0007] In summary, the limitations of existing wave power generation devices in terms of structural design, energy efficiency conversion and cost control have seriously affected the further development and large-scale commercial application of wave power generation technology. Therefore, developing a wave power generation device with optimized structure, high energy efficiency conversion efficiency and low cost is of great practical significance for promoting the effective development and utilization of wave energy and promoting the development of renewable energy. Summary of the invention

[0012] A generator is installed at the central connecting position of the first connecting bridge and the second connecting bridge. The generator rotor is connected to the generator cylinder shaft through a movable steering shaft. The bottom end of the generator cylinder shaft is connected to the square inner shaft of the power cylinder. The outside of the square inner shaft of the power cylinder is sleeved with a square outer shaft of the power cylinder. The bottom of the square outer shaft of the power cylinder is installed with an active power rotating float.

[0013] Furthermore, the top end of each of the upper columns is fixedly connected to the first connecting bridge and the second connecting bridge via steel wire ropes.

[0014] Furthermore, a bridge side bracket is provided on the outer wall of the outer support column facing the main power rotating float, and the bridge side bracket is fixedly connected to the first connecting bridge and the second connecting bridge by a steel wire rope.

[0018] By optimizing the design of the connecting bridge and using lightweight and high-strength materials, the device can more effectively capture the kinetic energy of waves. The optimization of the connecting bridge structure increases the contact area between the device and the waves, which can fully absorb the kinetic energy of waves in different directions. The lightweight and high-strength materials can reduce the weight of the device itself while ensuring the structural strength, reducing the inertia loss during wave impact, thereby improving the kinetic energy conversion efficiency.

[0019] 2. Effectively reduce costs

[0020] The wave power generation device focuses on economy in material selection and design; on the one hand, economical and practical materials are selected to reduce material costs while ensuring performance; on the other hand, the design is simplified, the number and complexity of parts are reduced, the manufacturing process is simpler, the production cycle is shortened, and the manufacturing cost is reduced; the maintenance cost is also reduced due to the simplified structure and the durability of the materials. The device is not easily corroded and damaged in the marine environment, which reduces the frequency of repair and replacement of parts, and further saves maintenance costs during use.

[0021] 3. Improve system usability

[0022] This device uses a simplified energy calculation formula, so that ordinary users can easily understand the power generation capacity of the system without professional background knowledge. This simplified calculation method allows users to easily evaluate the power generation effect of the device according to the actual situation of the waves and their own needs, which provides convenience for the selection, installation and use of the equipment; at the same time, the operation and maintenance of the device are also simpler, and users can easily get started without complicated training and professional knowledge.

[0023] 4. Good scalability and adaptability

[0024] The wave power generation device has good scalability and can be flexibly adjusted and expanded according to actual needs; the design of four supporting columns and two connecting bridges enables it to support wave power generation technology exceeding 1 million kilowatts, making it possible to build large-scale wave power generation projects; at the same time, the device is also highly adaptable and can adapt to different sea conditions and meteorological conditions. The optimized connecting bridge design and lightweight and high-strength materials enable the device to maintain good stability and performance in various sea conditions, whether in offshore areas with large waves or offshore areas with relatively stable sea conditions, it can effectively capture wave kinetic energy and convert it into electrical energy.

[0025] V. Promoting the Development of Renewable Energy and Environmental Protection
