Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and more specifically, to a full-range wind turbine energy-concentrating wind power generation device. Background Technology

[0002] With the increasing global demand for clean energy, wind power, an important, renewable, and environmentally friendly method of energy generation, has received widespread attention and high regard from the international community. Wind power technology is also continuously advancing and improving.

[0003] Wind power, due to its environmentally friendly and economical characteristics, is considered one of the important directions for future energy development. It not only produces no pollutants but also has relatively low development costs, making it a sustainable energy solution. With continuous technological advancements and cost reductions, wind power is being used more and more widely globally, and its commercial development prospects are very broad.

[0004] The basic working principle of a wind power generation system is to use wind power to drive the wind turbine or blades to rotate, thereby converting the kinetic energy of the wind into mechanical energy, and then converting the mechanical energy into electrical energy through a generator. The structure of wind power generation systems on the market is diverse.

[0005] However, in natural wind resources, wind speeds below 3 m / s, especially low wind speeds of 1.0 to 3.0 m / s, are ubiquitous and widespread. Existing technologies struggle to capture and utilize these wind resources for power generation, resulting in significant waste. This invention creatively increases wind speeds from 1.0 to 3.0 m / s to a higher range of 6.0 to 15.0 m / s, and more than doubles the captured wind volume. This increases the wind speed and flow rate of the wind, integrating them into a suitable flow rate for wind power generation. Simultaneously, the tail of the wing is designed with a biomimetic nodular shape, further reducing resistance by 15-20% during wing rotation. Finally, the relatively small kinetic energy of the wind is converted into powerful mechanical energy, which is then converted into electrical energy by a generator – a novel wind power generation system. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide a full-area wind turbine wind power generation device. The rotating wind turbine is surrounded by a 360° ring of regularly distributed pressurized and amplified Venturi full-area wind-gathering devices. Furthermore, the entire wind turbine and the top of the Venturi full-area wind-gathering devices are completely sealed with a retractable wind shield to protect the entire wind power generation system from damage by strong winds. The wind turbine rotates in an environment free from crosswind interference, pressurizing and amplifying the natural breeze through the Venturi energy-gathering devices before applying it to the rotating wind turbine, thus converting the natural wind energy from waste into powerful mechanical energy.

[0007] The present invention achieves its objective by employing the following technical solution: A full-area wind turbine wind power generation device, characterized in that it comprises: a wind turbine assembly composed of 2-3 spiral wind turbine blades extending throughout the body, the lower end of the wind turbine assembly being fixedly connected to a wind turbine base assembly; a full-area wind concentrator system comprising several sets of Venturi wind concentrators, the several sets of Venturi wind concentrators being regularly distributed in a 360° ring around the wind turbine assembly, the Venturi wind concentrators being fixedly connected to a steel structure support, the steel structure support being fixedly connected to a column; the wind turbine base assembly comprising a generator and a suspension bearing seat, the generator being equipped with a continuously variable transmission and a clutch, the suspension bearing seat being fixedly connected to the wind turbine assembly, the output shaft bearing of the clutch being connected to the suspension bearing seat, the output shaft of the clutch being fixedly connected to the wind turbine assembly, and the column being fixedly connected to the generator.

[0008] As a further limitation of this technical solution, the Venturi air concentrator is provided with an air inlet on its outer side, and the Venturi air concentrator is provided with a throat corresponding to the air inlet. The Venturi air concentrator is fixedly connected to a negative pressure hood corresponding to the throat. The negative pressure hood is provided with a negative pressure air inlet. The throat and the negative pressure hood form an air outlet gathering area. The area ratio of the air inlet to the throat is 1:0.15~0.5.

[0009] As a further limitation of this technical solution, the working principle of the Venturi air concentrator is as follows: Taking a wind speed of 1.0~2.0 m / s, an air inlet with a diameter of φ1000 mm, and a throat diameter of φ400 mm as an example, then: According to the fluid continuity equation: A 1 u 1= A 2 u 2(1) in: A The cross-sectional area; u For flow rate; air inlet area A 1 = diameter 1m 2 ×π3.14÷4=0.785m 2 ; air outlet area A 2 = diameter 0.4m 2 ×π3.14÷4=0.1256m 2 ; According to the air inlet wind speed u 1 = 1 m / s From the fluid continuity equation, we can obtain: u 2 = 0.785m 2 ÷0.1256m2 =6.25 Based on the above calculations, the wind speed increased by 6.25 times; The diameter of the air outlet throat 4 was changed to φ350mm; The wind speed then increases to: air outlet area A 2 = diameter 0.35m 2 ×π3.14÷4=0.0961625m 2 ; According to the air inlet wind speed, it is still u 1 = 1 m / s From the fluid continuity equation, we can obtain: u 2 = 0.785m 2 ÷0.0961625m 2 =8.16 The wind speed increased by 8.16 times; The diameter of the air outlet throat 4 was changed to φ450mm; The wind speed then increases to: air outlet area A 2 = diameter 0.45m 2 ×π3.14÷4=0.0961625m 2 ; According to the air inlet wind speed, it is still u 1 = 1 m / s From the fluid continuity equation, we can obtain: u 2 = 0.785m 2 ÷0.1589625m 2 =4.93 The wind speed increased by 4.93 times; The ratio of the diameter of the air inlet to the diameter of the throat is appropriate, which transforms the wind force of the garbage wind with a speed of 1.0~3.0m / s in nature into a high-intensity and valuable golden wind with a speed of 5~15m / s. Moreover, the negative pressure air inlet can also draw in a double amount of air to ensure that the wind speed acting on the spiral blades reaches 5~15m / s, so that the micro wind speed is transformed into the golden wind speed, so as to fully meet the wind speed required for wind power generation. The wind speed at the throat is generally 6 to 15 times that at the air inlet. Moreover, a vacuum zone is formed at the negative pressure shroud, and some air is also drawn into the negative pressure air inlet. The two winds converge in the air outlet gathering area, forming an air volume of more than twice that of the air outlet gathering area. The wind force of the air volume acts on the spiral blades of the wind vane assembly that extend throughout the entire body. Finally, the wind vane assembly converts the wind kinetic energy into powerful mechanical kinetic energy, providing mechanical power to the generator below, thereby generating electricity.

[0010] As a further limitation of this technical solution, the two vertical plates on both sides of the Venturi concentrator are the arc-shaped wall plates of the Venturi concentrator.

[0011] As a further limitation of this technical solution, a set of Venturi air concentrator reinforcing ribs are connected inside the Venturi air concentrator.

[0012] As a further limitation of this technical solution, a top cover is provided directly above the wind vane assembly. The top cover is connected to the piston rod of a set of hydraulic cylinders, and each hydraulic cylinder is connected to the upper end of the corresponding Venturi wind concentrator.

[0013] As a further limitation of this technical solution, the column is fixedly connected to the foot plate.

[0014] As a further limitation of this technical solution, the wind vane base assembly is fixedly connected to the flywheel.

[0015] As a further limitation of this technical solution, the Venturi wind concentrator is an integral structure.

[0016] As a further limitation of this technical solution, the leading end of the spiral blade is provided with a biomimetic nodule in the shape of a sawtooth. When the spiral blade is rotating, the biomimetic nodule structure can reduce the air resistance of the spiral blade 2 by 15-20% and reduce noise.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are: 1. The Venturi wind concentrator of this invention has a suitable ratio between the inlet and throat diameters, which can convert the wind force of garbage wind with a speed of 1.0~2.0m / s in nature into a high-intensity, valuable golden wind with a speed of 6~15m / s. Moreover, the negative pressure inlet will also draw in a double amount of air, ensuring that the wind speed acting on the spiral blades reaches 5~10m / s, thus converting the low wind speed of garbage into a golden wind speed to fully meet the wind speed required for wind power generation. The wind speed at the throat is generally 6~15 times that at the inlet. In addition, a vacuum zone will be formed at the negative pressure shroud, and some air will also be drawn in at the negative pressure inlet. The two winds converge in the outlet gathering area, forming an air volume of more than twice that of the inlet. The wind force of this air volume acts on the spiral blades that extend throughout the entire blade assembly. Finally, the blade assembly converts the wind kinetic energy into powerful mechanical kinetic energy, providing mechanical power to the generator below, thereby generating electricity.

[0018] 2. The wind vane assembly of the present invention has a 360° ring-shaped distribution of 3 to 12 sets of Venturi wind concentrators in a global wind-gathering system. In addition to converting the natural winds into golden wind speeds, it can also accelerate the wind blowing on the front of the wind vane assembly for direct wind power generation. There are sometimes some side winds on its sides, most of which are ineffective winds. These ineffective side winds are also collected, corrected, rectified, pressurized, and increased in volume by the Venturi wind concentrator arc-shaped wall plate, and transformed into useful and effective winds that can do work on the spiral-shaped wind vane blades that extend throughout the body.

[0019] 3. The wind vane assembly of the present invention will rotate in an environment without crosswind interference, and some of the wind that is not discharged in time will continue to descend. Since the wind vane assembly is composed of 2 to 3 spiral structures, the descending tail wind will also compress the spiral wind vane blades to make mechanical rotation, which has a certain auxiliary driving effect.

[0031] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0032] The present invention includes: a wind vane assembly 1, composed of 2-3 spiral wind vane blades 2 extending throughout the body, the lower end of the wind vane assembly 1 being fixedly connected to a wind vane base assembly 18; a global wind concentrator system including several sets of Venturi wind concentrators 3, the several sets of Venturi wind concentrators 3 being regularly distributed in a 360° ring around the wind vane assembly 1, the Venturi wind concentrators 3 being fixedly connected to a steel structure support 9, the steel structure support 9 being fixedly connected to a column 8; the wind vane base assembly 18 including a generator 6 and a suspension bearing seat 7, the generator 6 being equipped with a continuously variable transmission and a clutch, the suspension bearing seat 7 being fixedly connected to the wind vane assembly 1, the output shaft bearing of the clutch being connected to the suspension bearing seat 7, the output shaft of the clutch being fixedly connected to the wind vane assembly 1, and the column 8 being fixedly connected to the generator 6.

[0033] The output shaft of generator 6 is connected to the input shaft of continuously variable transmission (CVT), and the output shaft of CVT is connected to the input shaft of clutch.

[0034] The wind vane assembly 1 will rotate in an environment without crosswind interference, and some of the wind that is not discharged in time will continue to descend. Since the wind vane assembly 1 is composed of 2 to 3 spiral structures, the descending tail wind will also compress the spiral wind vane blades 2 to make mechanical rotation, which has a certain auxiliary driving effect.

[0035] The height of the wind vane assembly 1 is generally between 1m and 10m, or even higher, while the height of the venturi wind concentrators 3, which are regularly distributed in a ring around it, is the same as that of the wind vane assembly 1 and matches it.

[0036] The pitch of the spiral blade 2 is generally large, around 600~1000mm.

[0037] The wind vane assembly system 1 and the Venturi wind concentrator system 3 can be made of carbon steel plate or stainless steel plate by stamping and welding, or they can be made of non-metallic materials such as carbon fiber, basalt wire, fiberglass, nylon, and resin, as long as they have the characteristics of high strength, corrosion resistance, wear resistance and light weight.

[0038] The Venturi wind concentrator 3 can also be supported independently.

[0039] The wind vane assembly 1 can be used as a wind power generation device or a hydro power generation device; it can be placed vertically to form a vertical axis wind power generation device system; it can also be placed horizontally or tilted to become a horizontal axis wind power generation device system or a low head hydro power generation device system. The wind turbine assembly 1 and the ring-shaped Venturi wind concentrator 3 form an integrated system. They can be placed vertically to form a vertical axis power generation system, or placed horizontally to form a horizontal axis wind power generation system or a hydropower generation system. The Venturi air concentrator 3 has an air inlet 20 on its outer side. The Venturi air concentrator 3 has a throat 4 corresponding to the air inlet 20. The Venturi air concentrator 3 is fixedly connected to a negative pressure shroud 17 corresponding to the throat 4. The negative pressure shroud 17 has a negative pressure air inlet 15. The throat 4 and the negative pressure shroud 17 form an air outlet gathering area 14. The area ratio of the air inlet 20 to the throat 4 is 1:0.15~0.5.

[0040] A negative pressure shroud 17 is provided outside the throat 4. Its structure is a coupling body that matches the throat 4. There is generally a gap of 30 to 60 mm between the two. As long as there is air blowing into the Venturi concentrator 3 from the air inlet 20, a negative pressure space will be formed inside the negative pressure shroud 17, and a certain amount of air will enter the negative pressure air inlet 15. The air volume and pressure of the negative pressure air inlet 15 are determined by the wind force and air volume formed by the area of ​​the throat 4. The gap of the negative pressure air inlet 15 can be set according to the actual situation, and is generally 30 to 60 mm wide.

[0041] A single Venturi air concentrator 3 can be configured such that the air inlet 20 is square and the air outlet 4 is also square; or the air inlet 20 is round and the air outlet 4 is also round; or the air inlet 20 is square and the air outlet 4 is round; or the air inlet 20 is round and the air outlet 4 is square. The area ratio of the air outlet to the air outlet 4 can be flexibly set and can be selected between 1:0.15 and 0.5.

[0042] The working principle of the Venturi air concentrator 3 is as follows: In nature, under normal weather conditions, wind speed is generally low and wind direction is occasionally somewhat unstable, typically around 1.0~2.0 m / s. Using the Venturi concentrator 3, we can illustrate the wind speed and volume after concentrating the wind. For example, if the inlet 20 has a diameter of φ1000 mm and the throat 4 has a diameter of φ400 mm, then: According to the fluid continuity equation: A 1 u 1= A 2 u 2(1) in: A The cross-sectional area; u For flow rate; air inlet area A 1 = diameter 1m 2 ×π3.14÷4=0.785m 2 ; air outlet area A 2 = diameter 0.4m 2 ×π3.14÷4=0.1256m 2 ; According to the air inlet wind speed u 1 = 1 m / s From the fluid continuity equation, we can obtain: u 2 = 0.785m 2 ÷0.1256m 2 =6.25 Based on the above calculations, the wind speed increased by 6.25 times; If the diameter of the air outlet throat 4 is changed to φ350mm; The wind speed then increases to: air outlet area A 2 = diameter 0.35m 2 ×π3.14÷4=0.0961625m 2 ; According to the air inlet wind speed, it is still u 1 = 1 m / s From the fluid continuity equation, we can obtain: u 2 = 0.785m 2 ÷0.0961625m 2 =8.16 The wind speed increased by 8.16 times; If the diameter of the air outlet throat 4 is changed to φ450mm; The wind speed then increases to: air outlet area A 2 = diameter 0.45m2 ×π3.14÷4=0.0961625m 2 ; According to the air inlet wind speed, it is still u 1 = 1 m / s From the fluid continuity equation, we can obtain: u 2 = 0.785m 2 ÷0.1589625m 2 =4.93 The wind speed increased by 4.93 times; In other words, if the diameter ratio of the air inlet 20 to the throat 4 of the Venturi wind concentrator 3 is appropriate, it can convert the wind force of garbage wind with a speed of 1.0~3.0m / s in nature into a high-intensity, valuable golden wind with a speed of 5~15m / s. Moreover, the negative pressure air inlet 15 can also be drawn in a double amount of wind to ensure that the wind speed acting on the spiral wind blades 2 reaches 5~15m / s, so that the garbage wind speed is converted into a golden wind speed to fully meet the wind speed required for wind power generation. The wind speed at the throat 4 is generally 6 to 15 times that at the air inlet 20. Moreover, a vacuum zone is formed at the negative pressure shroud 17, and some air is also drawn into the negative pressure air inlet 15. The two winds converge at the air outlet gathering area 14, forming an air volume of more than twice that at the air outlet gathering area 14. The wind force of the air volume acts on the spiral blades 2 that extend throughout the entire body of the wind blade assembly 1. Finally, the wind blade assembly 1 converts the wind kinetic energy into powerful mechanical kinetic energy, providing mechanical power for the generator 6 below, thereby generating electricity.

[0043] Most natural wind resources have flow velocities below 3 m / s, especially the abundant low-speed breezes of 1.0 to 3.0 m / s, which are difficult to capture and are considered "garbage breezes," unsuitable for direct use in wind power generation. This invention creatively applies 3 to 12 sets of Venturi wind collectors 3 in a regular 360° pattern around the wind vane assembly 1 to form a 360° all-area wind collection system. This system can transform unusable low-speed breezes of 1.0 to 2.0 m / s into a larger wind speed of 5.0 to 15.0 m / s or more, converting them into the optimal wind speed for wind power generation. Furthermore, it can more than double the captured wind volume. Finally, the breeze is transformed into a doubled volume with the wind speed controlled at 5 to 15 m / s, converting the garbage breeze into the optimal wind speed to fully meet the wind speed requirements for wind power generation.

[0044] The vertical plates on both sides of the Venturi air collector 3 are Venturi air collector arc-shaped wall panels 16.

[0045] The 360° circumference of the wind vane assembly 1 is surrounded by 3 to 12 groups of Venturi wind collectors 3 forming a comprehensive wind-gathering system. This system not only converts natural winds into optimal wind speeds but also accelerates the wind blowing directly onto the wind vane assembly 1 for direct wind power generation. While there are occasional side winds, mostly ineffective, these are collected, corrected, rectified, pressurized, and amplified by the Venturi wind collector's curved wall plate 16, transforming them into useful, workable wind acting on the spiral-shaped wind vane blades 2 extending throughout the entire assembly. (See details...) Figure 5 .

[0046] Since the weather and wind direction at most points on Earth can change, the Venturi wind concentrator 3 of this invention can convert any light breeze blowing towards the front of the wind vane assembly 1 into a golden wind speed several times higher to meet the wind power generation needs of the wind vane assembly 1, even if the wind direction changes in any direction within 360°. At the same time, it can also capture, correct, rectify, pressurize, and increase the volume of light breeze blowing towards the side of the wind vane assembly 1, or when the wind direction changes. The Venturi wind concentrator 3 system, which is regularly distributed in a 360° pattern around the perimeter, can use the effective wind to drive the wind vane assembly 1 to do work, truly achieving all-round and all-domain capture of wind power and energy concentration to serve the wind vane assembly 1.

[0047] The Venturi air collector 3 is internally connected to a set of Venturi air collector reinforcing ribs 12.

[0048] A top cover 5 is installed directly above the wind vane assembly 1, effectively reducing the entry of impurities such as windblown sand, rain, and snow into the wind vane assembly 1, thereby reducing the degree of damage. At the same time, the low-velocity breeze is accelerated by the venturi concentrator 3 and then released through the throat 4. After acting on the spiral blades 2 of the wind vane assembly 1, most of the exhaust wind is discharged through the throat 4 of the opposite wind vane assembly 1. The top cover 5 is connected to the piston rod of a set of hydraulic cylinders 19. Each hydraulic cylinder 19 is connected to the upper end of the corresponding venturi concentrator 3. Based on the data obtained by the wind sensor, when there are significant changes in the weather, the PLC or AI intelligent automatic control system can control the hydraulic cylinders 19 to raise and lower, adjusting the top cover 5 to cover the venturi concentrator 3 at different heights to protect the safety of the entire wind power generation system.

[0049] In the event of severe weather such as storms, when the wind speed exceeds 15 m / s, the data obtained by the wind sensor, combined with the stored data settings, will be used by an intelligent automatic control system such as a PLC or AI to control the descent range of the hydraulic cylinder 19 system and adjust the lifting height of the top cover 5 to cover the Venturi wind concentrator 3. This will prevent the wind from being too strong and will automatically cover all or part of the Venturi wind concentrator 3 system and the wind vane assembly 1 system, thus avoiding damage to the entire wind power generation system.

[0050] The column 8 is fixedly connected to the foot plate 10.

[0051] The wind turbine base assembly 18 is fixedly connected to the flywheel 11. When the wind turbine assembly 1 starts to rotate, it drives the flywheel 11 to rotate together from a low speed to a suitable speed. Then, it is coupled with the generator 6 through a continuously variable transmission and clutch device to do work and generate electricity together, so that the whole wind power generation system can rotate and generate electricity safely and stably.

[0052] The Venturi wind concentrator 3 can be a single, integral structure depending on its total height.

[0053] The spiral blade 2 has a biomimetic nodule 13 with sawtooth-like teeth at its tip or front end. When the spiral blade 2 is rotating, the biomimetic nodule 13 structure can reduce the air resistance of the spiral blade 2 by 15-20% and reduce noise.

[0054] Photovoltaic panels can be installed on relevant parts of the device facing the sun, such as the top cover 5, the column 8, the steel structure support 9, and the Venturi wind collector arc wall panel 16, to generate photovoltaic power, so that the device can achieve multi-energy complementarity.

[0055] This invention can be used in weak wind power generation systems, or as a horizontally placed micro-wind power generation device; it can also be used as a low-head hydropower generation system, and has a wide range of applications.

[0056] The above-disclosed embodiments are merely specific examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.

The two winds converge at the air outlet gathering area (14), forming a wind volume of more than 2 times that at the air outlet gathering area (14). The wind force of the wind volume acts on the spiral blades (2) that extend throughout the wind blade assembly (1). Finally, the wind blade assembly (1) converts the wind kinetic energy into powerful mechanical kinetic energy, providing mechanical power for the generator (6) below, thereby generating electricity.
