Description
Technical Field
The invention belongs to the technical field of wind motors, relates to improvement of output power and power generation efficiency of a vertical axis wind driven generator, and particularly relates to a vertical axis wind driven generator with a wind collecting body.
Background
The world is facing serious crisis of energy shortage and crisis of environmental pollution, greenhouse gas emission and the like. People pay more and more attention to energy consumption problems and global climate change problems, and countries in the world pay more and more attention to the development of clean and sustainable energy.
In recent years, wind power has been rapidly and widely developed as a clean, environmentally friendly and sustainable energy source, and wind power generation has become a main form of wind power utilization. Over the past few years, the cost of electricity generation has been decreasing, and in terms of wind power generation technology, traditional wind power generation technology has taken the best market for wind resource locations. Against the background of the rapid evolution of technology, the development of traditional wind power generation technology is expected to quickly encounter bottlenecks. There is a need to replace existing wind power generation technology as quickly as possible by proposing more efficient wind power generation technology, which has either greater generation power or higher wind energy utilization efficiency, thereby enabling the generation capacity to continue to increase.
The development of new wind power generation technologies in areas of lower wind energy density (possibly in urban areas) is a future trend, and can also lead the wind generator industry to develop new configurations to adapt to different environments, improve efficiency and reduce cost. Therefore, researchers have proposed different concepts in an attempt to improve the power generation efficiency of wind power generators in areas where the wind energy density is small. One of these methods of increasing efficiency is the Diffuser Augmented Wind Turbine (DAWT), which increases the Wind energy utilization of the Wind Turbine by increasing the mass flow and Wind speed through the rotor section. Except for the common horizontal Axis Wind turbine, a vertical Axis Wind turbine vawt (vertical Axis Wind turbine) is also provided, which comprises a blade, a main shaft and a generator, is a device for converting kinetic energy in flowing air into electric energy, and has the characteristics of low noise, low pneumatic Wind speed, stable structure, long fatigue life, no need of yawing to Wind and the like, thereby being widely concerned. There are two main types of vertical axis wind turbines. One is a resistance type, which utilizes resistance rotation to generate electricity, and the typical type is a Savonius type, which has larger starting torque, low tip speed ratio and low output power (< 15%) of electricity generation under the same size. The other type is a Darrieus type, and the wind direction does not need to be influenced when changed, so that the structural design is simplified, and the gyro moment of the wind wheel when influenced by wind is reduced. The Darieus wind wheel is a lifting device, the section of a curved blade is an airfoil, the starting moment of the Darieus wind wheel is low, but the tip speed ratio can be very high, the structure is simple, and the Darieus wind wheel has higher power output (30% -40%) under the same size. At present, the mainstream model of the wind power industry is a horizontal axis three-blade type wind power generator, mainly because the power generation efficiency of the horizontal axis wind power generator is higher (40% -50%) than that of the vertical axis wind power generator. Therefore, although the darrieus wind turbine has many advantages, the power generation efficiency is lower than that of the horizontal shaft by about 25%, and further development of the darrieus wind turbine is restricted.
The wind collector structure can greatly improve the output power of a horizontal axis wind turbine and a vertical axis wind turbine, but the huge additional structure also causes a larger wind resistance effect, so that the wind load of the whole structure is increased by 2-3 times compared with the prior structure. At high wind speeds, difficulties are created in the safety of the structural design. Therefore, if a simple structure is provided, the original speed increasing characteristic of the wind collecting body structure can be ensured, and the wind load can be reduced at high wind speed, so that the wind turbine has important significance for popularizing the application of the wind turbine.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a wind collecting body structure with a flexible flange, so that the wind collecting body structure can obviously improve the wind power generation efficiency while keeping the original advantages, and can reduce the wind load through the self-adaptive deformation of the flexible structure when the wind speed is higher.
In order to solve the technical problem of low energy utilization efficiency of the vertical axis wind turbine, the invention adopts the technical scheme of the vertical axis wind turbine with the wind collecting body. The generator comprises a Darrieus vertical axis wind turbine which is composed of a base, a rotating shaft, blades and a frame. The base is used for fixing a rack of the wind driven generator to enable the rack to be stable when the wind is received, the blades rotate in a vertical plane around the rotating shaft, the blades are double blades, and the wind collecting body is also composed of a diffuser and a self-adaptive flexible flange and is arranged outside the wind driven generator. The diffuser is in a smooth transition curved surface and is used for improving the wind speed flowing through the wind collecting body, the flexible flange is in a double-cantilever structure, one end of the flexible flange is connected with the rack, the other end of the flexible flange is attached to the diffuser, the flexible flange is not opened before the rated wind speed, even if the front plate slightly deforms, the rear plate hardly deforms so as to ensure the wind gathering effect of the wind collecting body, when the wind speed exceeds the rated wind speed, airflow can flow out from an opening part where the flexible flange is attached to the diffuser in a large quantity, the gas flow passing through the blades is reduced, meanwhile, the wind load acting on the blades is also reduced, and the structural change of the wind collecting body has continuity.
Preferably, the vertical axis wind turbine is an H-type three-blade darrieus vertical axis wind turbine.
Preferably, the blade is a double blade.
The flexible flange of the wind collecting body is not opened before the rated wind speed so as to ensure the wind collecting effect of the wind collecting body.

(1) the invention utilizes the strong vortex formed by the flexible flange at the outlet of the wind collecting body to generate a low-pressure area, and the flow of wind in the wind collecting body is increased along with the increase of the pressure difference of the inlet and the outlet of the wind collecting body, so that the wind speed of the wind driven generator can be improved by introducing the wind collecting body structure, and the output power and the generating efficiency of the vertical axis wind driven generator are greatly improved;
(2) the adopted vertical axis wind turbine is an H-shaped Darrieus vertical axis wind turbine, so that the characteristics of simple structure, low starting wind speed and the like of the vertical axis wind turbine are reserved;

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
The invention provides a vertical axis wind driven generator with a wind collecting body, which is formed by combining a traditional vertical axis wind driven generator and the wind collecting body; the wind collecting body is composed of a diffuser and a self-adaptive flexible flange, the diffuser is used for improving the wind speed flowing through the wind collecting body, the flexible flange is of a double-cantilever structure, one end of the flexible flange is connected with the rack, and the other end of the flexible flange is attached to the diffuser, so that the function of fixing the wind collecting body is achieved, and as shown in figure 1, the wind collecting body is arranged outside the wind power generator. The torque coefficient of the wind collection body structure vertical axis wind turbine is larger than that of the traditional vertical axis wind turbine, which shows that the torque of the vertical axis wind turbine added with the wind collection body structure is larger than that of the traditional vertical axis wind turbine, and the wind collection body structure can effectively improve the power generation efficiency.
Since the mechanical energy obtained by the wind turbine from the wind energy is proportional to the third power of the wind speed, a large increase in the amount of generated electricity can be achieved by a slight increase in the incoming wind speed. By utilizing the theory, the wind turbine system adopted by the invention consists of a diffuser, a flexible flange arranged at the periphery of an outlet and a wind turbine. The flexible flange at the outlet of the wind-collecting body will form strong vortices, creating a low-pressure region, which will increase the fluid flow velocity, as known from bernoulli's equation. Along with the increase of the pressure difference of the inlet and the outlet of the wind collecting body, the flow of wind in the wind collecting body is also increased. Therefore, the output power can be greatly improved by adding the wind collecting body structure.
As shown in fig. 1 and 2, the invention provides a vertical axis wind turbine with a wind collecting body, which is formed by combining a traditional vertical axis wind turbine and the wind collecting body, wherein the wind collecting body structure comprises a diffuser and a self-adaptive flexible flange. The base 1 is used for fixing the whole frame, the double blades 4 rotate in a vertical plane around the rotating shaft 3, and the wind collecting body 2 is arranged outside the wind driven generator and consists of a diffuser and a self-adaptive flexible flange. The invention can effectively improve the wind speed passing through the wind collecting body, thereby improving the wind energy utilization rate and effectively increasing the generating efficiency of the vertical axis wind driven generator through the structural design.
The working principle of the generator is as follows: in the flow field, strong vortex can be formed due to the flexible flange at the wind collecting body outlet, and a low-pressure area is generated. Along with the increase of the pressure difference of the inlet and the outlet of the wind collecting body, the flow of wind in the wind collecting body is also increased. Therefore, the output power of the vertical axis wind driven generator can be greatly improved by adding the wind collecting body structure.
Fig. 3 is a schematic diagram of the principle of the adaptive flexible flange, and the significance of the diagram lies in that the opening of the flexible flange is accurately controlled through a simple double-cantilever structure. Wherein Vr is a rated wind speed, namely the optimal generating wind speed of the wind driven generator. V is incoming wind speed, Open gap is opening displacement, Ux、UyRespectively displacement in the x and y directions. By adding the wind collecting body mechanism, the wind flow passing through the blades in unit time is increased, and the power generation efficiency is improved. Before rated wind speed, the flexible flange of the wind collecting body is not expected to be opened, so that the wind collecting effect of the wind collecting body is ensured. When the wind speed exceeds the rated wind speed, the blades stall to reduce the generating efficiency, and simultaneously, the wind load is increased, so that the difficulty is brought to the structural design and the cost budget. At the moment, the airflow flows out from the opening in a large quantity through the self-adaptive deformation of the flexible flange, so that the airflow passing through the blade is reduced, and the wind load acting on the blade is reduced.
Fig. 4 is a schematic structural diagram of a wind collecting body, incoming wind enters a diffuser of the wind collecting body from the left side through a wind wheel rotating surface 6, a flexible flange 7 is connected with the diffuser 5, and the flexible flange at the outlet of the wind collecting body forms strong vortex to generate a low-pressure region 8. The formation of a low pressure region increases the fluid flow velocity, as known from bernoulli's equation. Along with the increase of the pressure difference of the inlet and the outlet of the wind collecting body, the flow of wind in the wind collecting body is also increased. Therefore, the output power can be greatly improved by adding the wind collecting body structure.
FIG. 5 is a comparison graph of output power generated by a wind turbine with a wind-collecting body structure and a conventional three-blade horizontal-axis wind turbine. The experiment proves that the air collecting body structure increases the air pressure difference of the front inlet and the rear inlet by changing the surrounding flow field, thereby improving the flow velocity of the airflow flowing through the air collecting body diffuser, playing a role of flow absorption effect and finally improving the generating efficiency of the wind turbine.
FIG. 6b is an experimental apparatus of the influence of the wind-collecting body structure on the output power of the vertical axis Darrieus wind turbine. Fig. 6a is a plan view of the wind collector structure. The meaning of the parameters in the figure: l: diffuser hypotenuse length of wind-collecting body, phi: diffuser hypotenuse angle, D: blade revolution diameter, h: the flexible flange height of the wind-collecting body.
FIGS. 7 and 8 are measured data of the influence of wind collectors with different structural parameters on the output power of a vertical axis Darrieus wind turbine. The influence of the wind collectors (h is 0.25D, phi is 20) with two structural parameters on the output power of the vertical axis Darries wind turbine under different tip speed ratios is compared. The wind collecting body structure is shown to have a remarkable effect on improving the power generation efficiency of the vertical axis Darrieus wind turbine.
FIG. 9 is a schematic diagram of an output power simulation analysis of a two-bladed Darries wind turbine. The output power of the traditional Darries wind turbine is low through verification from two aspects of experiments and numerical simulation.
FIG. 10 is a diagram illustrating the effect of the wind-collecting body structure on the improvement of the output power of a two-bladed Darrieus wind turbine. The effect of the wind collecting body structure on the vertical axis Darries wind machine in the aspect of improving the power generation output power is verified from two aspects of experiments and numerical simulation.
In summary, the invention utilizes the low pressure area generated by strong vortex formed by the flexible flange at the outlet of the wind collecting body, and the flow of wind in the wind collecting body is increased along with the increase of the pressure difference of the inlet and the outlet of the wind collecting body, so that the wind speed of the wind driven generator can be improved by introducing the wind collecting body structure, the output power and the generating efficiency of the vertical axis wind driven generator can be greatly improved, the experiment verifies that the wind load can be improved by 45%, and meanwhile, the wind load can be reduced by the self-adaptive deformation of the flexible structure when the wind speed is higher.
