technical field

Background technique

Humans have used green and renewable wind energy to provide services for social production and life for hundreds of years, from the ancient use of sail-type wind wheels to lift water, to the use of sails for long-distance sailing, and the world-famous Dutch windmill, to the modern horizontal axis / Vertical axis wind power generation. With the changes of the times, the wind power application technology has been continuously upgraded, changed, perfected and innovated, creating a technological improvement one by one, providing services for human production and life. As far as the existing traditional wind power generation system is concerned, from the perspective of application, it seems that the limit of wind energy application has been reached. Because the wind energy captured by the fan blades is proportional to the swept area of the fan and the cube of the wind speed through the fan, the wind speed is determined by the climate conditions and cannot be changed by humans. However, an effective way to improve wind energy utilization and power generation efficiency is to increase the wind-capturing capacity of wind blades. For this reason, the current conventional method is to increase the wind sweep area by continuously increasing the size of the fan blades, so as to capture more wind energy to improve the wind power of a single machine. Effective wind power conversion amount. But the result is that the stability of power generation and the security of the system are sacrificed. Looking at the characteristics of various wind power generation systems in the existing domestic and foreign markets, it is not difficult to see several major problems: 1. Low power generation efficiency; 2. Too large and too long blades; Difficulty; 4. Low return on investment; 5. Poor safety; 6. Serious noise pollution.

Experts, scientific and technological personnel, and industry elites from various countries have made unremitting efforts to study these issues in depth, in order to strive for breakthroughs, find alternative methods and models to solve these problems, and hope to contribute to the sustainable development of society. However, it is an alternative new type of special model that can really be popularized and applied, adapt to large-scale deployment, and can be easily transported, flexibly installed, and intensively generated for power generation. Whether it is professional manufacturing technology, proprietary installation equipment, or full-time engineering technology There are very few people. In the field of traditional wind turbines, compared with advanced countries in the world, there is still a certain gap in manufacturing technology between my country and the world, and many core technologies are still in the hands of a few developed countries. It is one of the important contents of my country's "12th Five-Year Plan" to break through the technical bottleneck, create my country's own original technology, participate in the international big market competition, and enhance the popularity and market share in the core technology field of wind power, which is also completely suitable for my country. Plans and strategic decisions for the use of renewable energy.

So far, in the field of narrow-tube wind-gathering turbine wind power generation, no matter in the selection and production technology of the air inlet cover, the security technology for avoiding inclement weather raids, or the ratio matching technology of the inlet and outlet of the narrow tube, the anti-seismic and system of the skeleton There are no basic materials and application examples for reference in building integration technology, high-efficiency air turbine manufacturing technology, and system control man-machine integration technology. Although existing narrow-tube wind power generation in a few developed countries, such as the United Kingdom and Denmark, only utilizes nature or the narrow tubes formed between buildings, the promoted wind speed is very limited, which is completely different from the present invention.

working principle:

Regardless of the wind blowing from any direction, the wind direction sensor, wind pressure sensor, and wind speed sensor will transmit the data collected in real time to the DCS intelligent control center at the first time. The gearbox on the platform sends out an instruction, and the gearbox immediately starts the transmission mechanism after receiving the instruction, so that the transmission gear in the transmission mechanism drives the gear ring to rotate in the specified direction, correctly aligns with the direction of the incoming wind, and the brake starts to engage and position. In the event of a strong storm or typhoon, the bowler-hat-type wind gathering device will turn its head to avoid movement under the unified command of the DCS intelligent control center, stop at the safest position, and close the wind-discharging opening and closing door at the same time, so that the entire system Always be on the safe side.

According to Bernoulli's law, the pressure of the fluid with a fast flow rate is small, and the fluid with a slow flow rate nearby will be sucked in by the pressure difference, so when the wind enters from the air gathering port, it will also drive the diffuse free air volume passing around the air gathering port to enter together. . Because the low-speed air is almost incompressible, the flow velocity is continuously accelerated by the shrinking narrow tube, from about 5 m/s of the original third-level wind speed to 70-80 m/s at the exit of the narrow tube. At this time, the working medium flow will generate more turbulence and turbulence. When the strong working medium flow enters the spiral guide plate, all the working medium flow undergoes a spiral solid-phase structure specification, and gradually forms another style, the tornado Formed from this. The high-speed tornado sucks the free and diffuse wind energy sucking outside the window into the swirling flow while generating rotation, thereby increasing the energy, filling the tornado wind column, strengthening the rotating force and generating a strong torsion force at the same time. According to Bates theory, ideally, the first-stage fan can convert up to 16/27 of the wind energy, which is about 59.3%, into mechanical energy. For this purpose, multi-stage fans can be designed to convert more than 70% of the wind energy into mechanical energy. The specific process is that, under the action of strong wind speed and full wind pressure, when passing through the wind guide regular plate set in front of the turtle back blade, due to the spiral shape of the wind guide regular plate, the wind is jetted from the original turbulent flow of mutual extrusion. The shape is transformed into a regular multi-swirl tornado shape, and the impact of the turtle back blade drives the step-by-step power shaft to rotate. After the first-level energy conversion, the wind carrying the remaining energy is guided by the second-level spiral air guide and regulation plate , colliding with the second-stage turtle-back blade, so that the power axis of the hierarchy is strengthened with energy, and the wind with remaining energy after part of the energy conversion passes through the third-stage wind guiding regular plate and collides with the third-stage turtle-back leaf, forming the rotating tornado energy Once again, the stepping power shaft is driven to run, and the running of the stepping power shaft simultaneously drives the power output gear arranged on the shaft head to rotate together with the central shaft head gear of the generator, drives the generator to run, and converts mechanical energy into electric energy. In this way, the whole process of efficient conversion of wind energy into mechanical energy and mechanical energy into electrical energy is completed, and the remaining wind is discharged from the gradually expanding air discharge channel to the open air release door and returns to nature.

The bowler hat body 11 is characterized in that: the central outer arc surface of the bowler hat body 11 is provided with a central limiting shaft cylinder 21 with a diameter of 500-5000 mm, and a convex ring is arranged circumferentially on the central limiting shaft cylinder 21 . The air gathering port 51 is arranged on the windward side of the bowler hat body 11, and the air gathering port 51 opens a hole with a diameter ranging from 2 to 150 meters as required; or opens an air gathering outlet with a diameter of 4 to 146 meters directly below and extends downward. A cylinder ring is provided at the time, and the diameter of the cylinder ring is equivalent to the size of the opening directly below. At the same time, a protective grid 7 is installed at the opening.

The bowler hat body 11 is applied in a single group with a large size, and it can also be used in multiple groups of medium and small sizes with a corresponding interval of 2-5 groups for joint application. No matter how many groups of methods are used, they all need to be connected to the same narrow-tube type working fluid speed-up device assembly at the end.

No matter what kind of material is used to make the support column 3, the support column 3 and the adjacent support column 3 must be fixedly connected by an annular ring beam 4 to improve the overall fastness, wind resistance and earthquake resistance level.

A self-starting narrow-tube wind-gathering wind power generation system of the present invention has a number of excellent core technologies and excellent cost-effective advantages, the details are as follows:

1. Bowler-hat wind gathering technology with outstanding wind gathering ability is the best choice for narrow tube wind power generation.

 Using alloy materials as the main reinforcement, coupled with new composite materials as the inner and outer skins of the bowler hat. The main material is made of the special shape of the front opening and the lower opening of the spheroid, and the spheroid has a strong pressure bearing capacity, a small flow resistance coefficient of the working fluid, timely wind gathering and diversion, is not easy to produce turbulent flow and eddy current phenomenon, and can be adjusted Features such as wide range. According to Bernoulli's law, the bowler hat air gathering port can completely collect the diffuse and free wind energy in the front and surroundings, and improve the wind gathering capacity to be more than 100% of the original air gathering port. At the same time, it has the advantages of light weight, strong wind resistance, long service life, safe and convenient transportation, easy purchase of required materials, easy manufacture, and maintenance-free.

2. Avoiding violent deflection closing technology has substantially improved the self-protection awareness of wind power generation.

As we all know, whether it is a horizontal axis wind turbine or a vertical axis wind turbine, it is difficult to respond quickly when avoiding a sudden storm or typhoon. The blades are broken and the main engine cannot be twisted. Therefore, over the past few years, the damage has been serious and maintenance has been difficult, causing investors to complain. And one of the cores of the present invention is the anti-violence deflection closing technology, which adopts the active response method in case of rape and typhoon, automatically turns the head to the safest position, implements avoiding danger, and starts the wind-discharging opening and closing door to close and block at the same time, and a group of upper A combined punch that turns the head, deflects, and closes the door. It solves the difficult operation that is difficult to complete in traditional wind power generation, greatly improves the safety of the entire wind power system, and also sets a model for the future narrow tube wind power generation in the field of safety.

3. Multi-stage progressive expansion air turbine engine technology converts more wind energy into mechanical energy, and more mechanical energy can be converted into electrical energy.

Just imagine, the air gathering port of the bowler hat adopts a 30-meter-diameter circular hole with four wind speeds according to the normal wind gathering method, while the first stage of the air turbine engine has a diameter of 5 meters, the second stage is 5.5 meters, and the third stage is 6 meters. Withstand the imported four-level wind condition. According to the theory that the wind speed is doubled and the wind energy is increased to 8 times as the calculation basis, the multiplier from the air gathering port to the first stage of the turbine engine is 36 times. According to scientific calculations, the wind speed will increase from the original 6-7 m/s to over 70-80 m/s, the first stage converts 40% of energy, the second stage converts 22% energy, and the third stage converts 13% energy , and about 20% of the energy remains when the remaining is removed. In this situation, it is not difficult to see its huge power generation capacity and its wake utilization value. In the multi-stage progressive expansion air turbine engine, one of the key core technologies of the present invention, although the energy conversion of each stage cannot exceed 59.3% of the Bates theoretical limit value, the use of multi-stage technology enables the total energy conversion to exceed 70%. Made of excellent composite materials, its special turtle-back blade shape and the cyclone-shaped regular plate made according to the research of aerodynamics greatly enhance the core values of the full-time air turbine engine, fully reflecting its high impact strength, The "unprecedented" pioneering features such as friction resistance, tensile damage resistance, multi-stage series connection, step-by-step expansion, flexible rotation, prominent pulling force, and high work efficiency completely solve the "worries" of future narrow-tube wind power generation without a full-time engine. It provides a "sample" with great reference value for "latecomers", and fills the gap at home and abroad.

4. The integrated technology of strong bones and anti-seismic components completely solves the "single-handed" structure of traditional wind turbines.

Both industry professionals and social science and technology personnel know that the existing horizontal-axis wind turbines and vertical-axis wind turbines cannot have the ability to collect wind in the air and generate electricity on the ground. Even if the vertical axis seems to be of this type, it often has low power. Large resistance, long transmission distance and "not long". Natural disasters such as rape, typhoon, and earthquake cannot be avoided. One of the core technologies of the present invention, the integrated technology of strong bones and anti-seismic components, adopts a scientific and reasonable circular appearance design, whether it is the main support column, the annular ring beam to the circular arched protective column, the annular ring seat, and the mechanical room. Meticulous construction, seamless. Reinforced concrete, steel frame structure or new composite materials are used as the overall material of the system, which has obvious advantages such as easy procurement, easy transportation, easy construction, maintenance-free, and a service life of up to 50 years. It greatly eliminates unnecessary economic losses that may be caused by natural disasters, and the earthquake resistance can reach level 8 or above. It has improved investor confidence and return on investment, and laid a solid foundation for giving full play to free wind collection in the air and steady-state power generation on the ground.

5. Narrow-tube working fluid speed-up technology creates a new model of wind power generation.

According to the principle that the air is approximately incompressible when the wind speed is lower than Mach 0.3, another core technology of the present invention: the narrow-tube working medium speed-up technology is another important technology after the bowler hat wind gathering device, and it is also a dual of a technology. aspect. The excellent combination of the excellent bowler-hat-type air gathering device coupled with the shrinking-type narrow-tube working medium speed-up device is adopted, and the upper and lower inner chambers are equipped with wheel-type anti-suction deflation devices and composite materials are used as the narrow-tube interior decoration. Not only the safety level in the cavity is improved, but also the smoothness of the cavity is improved. At the same time, through the built-in spiral guide plate in the narrow tube, the turbulent and vortex working medium flow is forced to standardize the spiral solid phase structure, forming a tornado working medium flow situation. The high-speed advancing working fluid sucks the free and diffuse wind energy outside the window into the swirling flow while generating rotation, filling the tornado wind column, strengthening the rotating force and generating a strong torsion force at the same time, thus solving the problem of high-power working medium flow. In the case of invasion, avoid generating more turbulence and vortex, which will affect the energy conversion efficiency of the turbine engine. At the same time, the wind energy entering the turbine engine can be used to cool down the turbine engine, take away the heat, and make the blades of the turbine engine lighter and smaller. Due to the use of high-magnification narrow tube speed-up technology, it can start generating power even at low wind speeds, which is also an incomparable major advantage of existing wind turbines, and will definitely make an outstanding contribution to the entire large system.

6. It is a high-quality project with great investment value due to its excellent work efficiency and excellent green energy creation ability.

The present invention not only has the above-mentioned many core technical advantages, but also has excellent cost performance and considerable economic benefits. has great significance.
