Description

Technical Field

[0001] The invention belongs to the technical field of wind power generation, and in particular relates to a superconducting air wind power generation system device. Background Art

[0002] As a clean and renewable energy source, wind energy is becoming increasingly important in the global energy structure. Traditional wind power generation technology mainly relies on wind power to directly drive generators to generate electricity. However, this method has many limitations. In low wind speed environments, the output power of wind turbines is low, and the power generation efficiency is greatly reduced, making it difficult to meet the demand for continuous and stable power supply. In addition, it is sensitive to changes in wind speed and direction. When the wind speed is unstable or the wind direction changes frequently, the performance of the power generation system will be significantly affected, resulting in unstable power quality. At the same time, traditional wind power generation equipment is usually large in size and occupies a large area. With land resources becoming increasingly scarce today, this shortcoming has become increasingly prominent. In addition, the installation and maintenance process of the equipment is complicated, requiring the cooperation of professional technicians and large equipment, which is costly, time-consuming and labor-intensive.

[0003] In order to overcome the above problems, the present invention provides a superconducting air wind power generation system equipment. The equipment adopts components such as air compressors, air tanks and air engines through a unique structural design, which first converts wind energy into air pressure energy for storage and regulation, and then drives the generator to generate electricity. This design enables the power generation system to still work effectively in a low wind speed environment, thereby improving the utilization rate of wind energy; it is more adaptable to changes in wind speed and wind direction, thereby ensuring the stability of power output; the system has a compact structure and occupies a small area; and it is relatively simple to install and maintain, thereby reducing the overall cost, providing a new solution for the development of wind power generation technology. Summary of the invention

[0004] The purpose of the present invention is to provide a superconducting air wind power generation system equipment, aiming to solve the many problems faced by existing traditional wind power generation technologies in the prior art, including insufficient output power under low wind speed conditions, unstable power generation due to the significant influence of changes in wind speed and wind direction, and large equipment size and excessive floor space. The present invention achieves a compact structure and effectively reduces the problem of floor space through its unique design.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A superconducting air wind power generation system comprises a fan column, the top end of which is fixedly connected to a connecting shell, the adjacent ends of the fan column and the connecting shell are connected to each other, a fan is installed at the front end of the connecting shell, an air compressor is installed in the connecting shell, three gas tanks are arranged on the circumferential inner wall of the fan column, an air motor and a gas tank are fixedly connected to the circumferential inner wall of the fan column, a fan support seat is fixedly connected to the bottom end of the fan column, a superconducting motor and a generator are installed in the fan support seat, the fan, air compressor, air motor, generator, superconducting motor, generator and three gas tanks are electrically connected, and the generator is electrically connected to an external grid-connected converter.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. In this scheme, air compressors, air tanks, air engines and other components are used to convert wind energy into air pressure energy for storage and regulation. When the wind speed is low, although the fan has a low speed, it can still drive the air compressor to work, compress the air and store it in the air tank. As the pressure in the air tank gradually increases, it provides a stable and powerful energy source for the air engine, so that the air engine can work continuously and stably, and then drive the generator to generate electricity. In this way, even in a low wind speed environment, the system can work effectively, improve the utilization rate of wind energy, ensure a certain power generation output, and enhance the adaptability of the power generation system under different wind speed conditions;

[0009] The gas tank plays the role of buffering and regulating energy. When the wind speed and wind direction change, the compressed air stored in the gas tank can maintain the stable operation of the air engine to a certain extent, reducing the impact of changes in external conditions on the power generation system. Even if the wind speed is unstable in the short term, the air engine can still rely on the energy in the gas tank to continue working, so that the generator outputs relatively stable electricity, effectively ensuring the stability of the power quality and improving the adaptability of the power generation system to complex natural environments.

[0010] 2. In this solution, the superconducting air wind power generation system equipment realizes a compact design of the system structure by rationally arranging various components, such as integrating the fan, air compressor, gas tank, air engine, superconducting motor and generator into the fan column and related supporting structures. Compared with traditional large wind power generation equipment, the present invention significantly reduces the footprint under the same power generation power, reduces the demand for land resources, is more convenient to install in various terrains and site conditions, improves the utilization efficiency of land resources, and also reduces the impact on the surrounding environment.

[0011] 3. In this solution, due to the compact system structure, the connection and layout between the components are more reasonable, the installation process is relatively simple, and does not require too many complex large-scale equipment and a large number of professional and technical personnel, thereby reducing the installation cost and time. In terms of maintenance, the relative concentration and reasonable layout of the components facilitate daily inspection, repair and replacement, reducing the need for high-altitude operations and complex operations. For example, maintenance of air compressors, air engines and other components can be carried out at a relatively low position, reducing the difficulty and risk of maintenance, thereby reducing maintenance costs, improving the maintainability and operational reliability of the equipment, ensuring the long-term stable operation of the power generation system, and improving economic benefits.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1

[0019] See also Figure 1-Figure 2 The present invention provides the following technical solutions

[0020] A superconducting air wind power generation system device comprises a fan column 1, the top of the fan column 1 is fixedly connected to a connecting shell 4, the adjacent ends of the fan column 1 and the connecting shell 4 are connected to each other, a fan 3 is installed at the front end of the connecting shell 4, an air compressor 5 is installed in the connecting shell 4, three gas tanks 7 are arranged on the circumferential inner wall of the fan column 1, an air motor 8 and the gas tank 7 are fixedly connected to the circumferential inner wall of the fan column 1, a fan support base 2 is fixedly connected to the bottom end of the fan column 1, a superconducting motor 10 and a generator 6 are installed in the fan support base 2, the fan 3, the air compressor 5, the air motor 8, the generator 9, the superconducting motor 10, the generator 6 and the three gas tanks 7 are electrically connected, and the generator 6 is electrically connected to an external grid-connected converter.

[0021] In a specific embodiment of the present invention, the fan column 1 serves as the supporting structure of the entire system and bears the weight of each component of the system. It provides a stable foundation for the installation of other components, ensuring that the system can remain upright and stable under various environmental conditions such as different wind speeds and wind directions, and ensuring the normal operation of the power generation system. At the same time, its internal space is used to accommodate key components such as gas tanks 7 and air engines 8, creating the necessary space environment for the entire power generation process. The fan 3, air compressor 5, air engine 8, generator 9, superconducting motor 10, generator 6 and three gas tanks 7 are electrically conductively connected.

[0022] The connecting shell 4 serves to connect the fan column 1 and the fan 3. On the one hand, it stably mounts the fan 3 on the top of the fan column 1 to ensure the stability of the fan 3 during the rotation process; on the other hand, it provides a suitable installation position for the air compressor 5. The connecting shell 4 enables the mechanical energy generated by the fan 3 to be effectively transmitted to the air compressor 5 to achieve the initial conversion of energy, and is an important link in the entire energy transmission chain.

[0023] The fan 3 is the starting part of the power source of the entire power generation system. When affected by wind, the blades of the fan 3 rotate, converting wind energy into mechanical energy. This mechanical energy is transmitted to the air compressor 5 through the connection structure, driving the piston of the air compressor 5 to operate, thereby starting the air compression process and providing the initial power input for the subsequent power generation process.

[0024] The air compressor 5 is responsible for compressing the air in the power generation system. Driven by the fan 3, the piston of the air compressor 5 moves, reducing the volume of the air and increasing the pressure. The compressed air enters the air tank 7 in a specific order. Through the compression of the air, the mechanical energy transmitted by the fan 3 is converted into the pressure energy of the air, which reserves energy for the subsequent operation of the air engine 8.

[0025] The three gas tanks 7 are containers for storing compressed air, and the gas tanks 7 play a key role in the entire power generation system. They store compressed air in a specific order and according to a specific rule. Gas tank No. 1 receives the gas generated by the air compressor 5, and outputs it to gas tank No. 2 after the gas accumulates to a certain level, and gas tank No. 2 then outputs it to gas tank No. 3. In this process, the gas pressure in the gas tank gradually increases, realizing the orderly storage and pressure increase of compressed air. This gradually increasing pressure provides a stable and powerful source of energy for the air engine 8, ensuring that the air engine 8 can work continuously and stably.

[0026] The air engine 8 is a core component that converts the energy of compressed air into mechanical energy. When the high-pressure gas in the No. 3 gas tank is released into the air engine 8, the gas pushes the piston in the air engine 8 to do work, converting the pressure energy of the gas into rotational mechanical energy. The output shaft of the air engine 8 is connected to the generator 6, thereby transmitting this mechanical energy to the generator 6 and driving the generator 6 to generate electricity.

[0027] The fan support base 2 is located at the bottom of the fan column 1, and is mainly used to support the entire power generation system, disperse the weight of the system, and ensure the stable installation of the system on the ground. At the same time, it provides a stable installation environment for the superconducting motor 10 and the generator 6, ensuring the stability and safety of these two key electrical components during operation.

[0028] The superconducting motor 10 works in conjunction with the air motor 8 during the power generation process. Its output shaft and the air motor 8 simultaneously provide power to the generator 6, increasing the input power of the generator 6 and improving the power generation efficiency. The superconducting motor 10 uses superconducting technology and has the advantages of low loss and high power density. It can output greater power under the same input conditions, providing strong support for the efficient operation of the entire power generation system.

[0029] The generator 6 is a key device for converting mechanical energy into electrical energy. After receiving the mechanical energy transmitted by the air engine 8 and the superconducting motor 10, the generator 6 generates electricity according to its own rated power. It converts the rotational mechanical energy into electrical energy, contributing to the ultimate goal of the entire power generation system - electrical energy output. The generated electrical energy then enters the grid-connected converter for subsequent processing.

[0030] The grid-connected converter processes the electric energy generated by the generator 6. It performs transformation operations such as rectification and inversion on the AC power output by the generator 6, and adjusts the parameters of the electric energy such as voltage and frequency to make it meet the access requirements of the power grid. After being processed by the grid-connected converter, the electric energy can be stably and safely connected to the power grid to realize external power supply.

[0031] Air compression stage: When there is wind outside, the wind acts on the blades of the fan 3, causing the fan 3 to start rotating. The rotation of the fan 3 drives the piston of the air compressor 5 in the connecting shell 4 to operate. The air compressor 5 starts to compress the air, and the compressed air generated first enters the No. 1 gas tank 7 located at the highest point through the fan column 1. As the fan 3 continues to rotate, the air compressor 5 continues to generate compressed air, and the gas in the No. 1 gas tank 7 gradually increases. When the gas storage volume and pressure in the No. 1 gas tank 7 reach a certain level, the gas begins to flow to the No. 2 gas tank 7. Similarly, when the gas storage and pressure conditions in the No. 2 gas tank 7 are met, the gas further flows to the No. 3 gas tank 7. In this process, due to the system design, the No. 1 tank 7 can only output gas to the No. 2 tank 7, and the No. 2 tank 7 can only output gas to the No. 3 tank 7. This one-way output mechanism ensures the orderly transmission of gas. Through the gradual storage and compression of the three gas tanks 7, the gas pressure in the gas tank 7 continues to increase, which reserves sufficient energy for the subsequent operation of the air engine 8.

[0032] Energy conversion and power generation stage: When the high-pressure gas in the No. 3 gas tank 7 reaches the working requirements, the gas is released through the pipeline and enters the air engine 8. Inside the air engine 8, the high-pressure gas pushes the piston to do work, so that the output shaft of the air engine 8 starts to rotate. The output shaft of the air engine 8 is connected to the generator 6 installed in the fan support seat 2, thereby driving the rotor of the generator 6 to rotate. At the same time, the superconducting motor 10 is also started and works in coordination, and its output shaft and the output shaft of the air engine 8 provide power to the generator 6 at the same time. Driven by the air engine 8 and the superconducting motor 10, the generator 6 converts the input mechanical energy into electrical energy according to its own rated power. The generated electrical energy is then transmitted to the external grid-connected converter through a cable. In the grid-connected converter, the electrical energy undergoes a series of processing, including voltage adjustment, frequency matching and other operations. Finally, after meeting the grid access requirements, the voltage is boosted and connected to the grid, and the electrical energy is stably transmitted to the external grid to complete the entire power generation process. During the operation of the entire system, the various components work closely together to make full use of wind energy resources and achieve efficient and stable power generation.

[0033] The working principle and use process of the present invention are as follows: when there is wind outside, the wind acts on the blades of the fan 3 installed at the front end of the connecting shell 4, prompting the fan 3 to rotate. The mechanical energy generated by the fan 3 is transmitted to the air compressor 5 in the connecting shell 4 through the structure connecting the fan column 1 and the connecting shell 4, driving the piston of the air compressor 5 to operate. The air compressor 5 compresses the air, and the compressed air generated enters the No. 1 gas tank 7, No. 2 gas tank 7, and No. 3 gas tank 7 arranged on the inner wall of the circumference of the fan column 1 in turn. Under the one-way output mechanism designed by the system, the No. 1 tank can only output gas to the No. 2 tank, and the No. 2 tank can only output gas to the No. 3 tank. The gas pressure in the gas tank 7 gradually increases, and energy is reserved for subsequent work. When the high-pressure gas in the No. 3 gas tank 7 reaches the working requirements, the gas is released through the pipeline and enters the air motor 8 fixedly connected to the inner wall of the circumference of the fan column 1, pushing the piston in the air motor 8 to work, so that the output shaft of the air motor 8 rotates. The output shaft of the air engine 8 is connected to the generator 6 installed in the fan support seat 2, driving the rotor of the generator 6 to rotate. At the same time, the superconducting motor 10 installed in the fan support seat 2 starts to work together, and its output shaft and the output shaft of the air engine 8 provide power to the generator 6 at the same time, increasing the input power of the generator 6 and improving the power generation efficiency. After the generator 6 converts the received mechanical energy into electrical energy, it is transmitted to the external grid-connected converter through a cable. In the grid-connected converter, the electrical energy undergoes a series of processing, including voltage adjustment, frequency matching and other operations, and finally achieves boosting and grid connection after meeting the grid access requirements, and stably transmits the electrical energy to the external grid. In this process, the fan column 1 serves as the supporting structure of the entire system, bearing the weight of each component of the system, providing a stable foundation for the installation of other components, and providing internal space for key components such as the gas tank 7 and the air engine 8; the connecting shell 4 connects the fan column 1 and the fan 3 and places the air compressor 5, thereby realizing the initial transfer of energy; the various components work closely together to make full use of wind energy resources, effectively solving the problems of traditional wind power generation technology such as low output power at low wind speeds, great influence of changes in wind speed and direction, large equipment size and wide area, etc., achieving the advantages of compact structure, small footprint, easy installation and maintenance, and reduced overall cost, thereby ensuring efficient and stable operation of the power generation system.
