Description
Technical Field
The invention relates to the field of wind power generation, in particular to a vertical axis wind driven generator system.
Background
Wind power generation is a clean and environment-friendly new energy source and has great development potential. For the wind energy utilization rate of the small horizontal axis wind driven generator, the wind tunnel general measurement which is related to the aerodynamic research and development center of China has been done, the actually measured wind energy utilization rate is about 23% -29%, and the wind energy utilization rate of the large horizontal axis wind driven generator is lower. However, the simulation result shows that the wind wheel utilization rate of the vertical axis wind wheel is not lower than that of the horizontal axis, and the foreign structure experiment also shows that the wind energy utilization rate of the vertical wheel is more than 40%. After eliminating the "loss to wind", the wind energy utilization of the vertical wheels is well likely to exceed that of the horizontal axis wind wheels.
In a vertical axis wind turbine, energy from natural wind is directed at rotating blades, whose impeller is supported on a vertical axis, and a generator is connected to convert the mechanical energy of the impeller rotation into electricity. Most of the existing vertical axis wind turbine products are small products, and Lafond wind wheels or Darieu wind turbines are adopted. The wind area is influenced by the windward side of the wind wheel, and the wind wheel blades are required to be made large to obtain wind power with higher power. The large-impeller vertical-axis wind wheel has the disadvantages of huge construction cost and low cost performance, so that the large-impeller vertical-axis wind wheel cannot be widely applied.
The vertical axis wind turbine is divided into a resistance type and a lift type.
The resistance type uses the resistance of the wind wheel to wind to do work, has simple structure, reliable operation, convenient installation and maintenance, large starting torque and the limitation of the rotating speed by the wind speed (the tip speed ratio is 0.5-
0.9), when the diameter of the wind wheel is large, the rotating speed is difficult to increase. In addition, only half of the wind area of the resistance type fan is utilized, and the other half of the wind area also does negative work in the forward and backward directions, so that the power coefficient of the resistance type vertical wind turbine is lower.
The lift type vertical fan applies work by utilizing lift force to wind, has small wind resistance compared with a resistance type fan, has high rotating speed and higher utilization rate of wind energy, the tip speed ratio of a blade end of the lift type vertical fan is usually more than 4, the maximum power coefficient can reach 50 percent, and the lift type vertical fan is mainly used for medium and small-sized wind power generation. The vertical wind turbine has small total torque, cannot be started by wind power, and can normally run by means of lift force only when the tip speed ratio reaches more than 3.5 by starting by means of external force. The lift type fan has high rotating speed, the impeller is repeatedly acted by centrifugal force, the diameter of the impeller is restricted by material performance, and the large-scale fan cannot be realized.
At present, most measures for reducing the wind loss are to adopt a wind shielding plate, and to adopt a mode of shielding incoming wind on the wind side to avoid the wind loss, but the incoming wind on the side cannot be utilized undoubtedly, so that the effective wind receiving area is reduced, the power generation power output is influenced, and the position of the wind shielding plate needs to be adjusted constantly according to the wind direction. The large vertical fan is difficult to produce, transport and install due to huge fan blades, so that the large vertical fan can not be used in a large wind turbine.

Fig. 3 shows that the drainage cover component is a cage-shaped hollow cylinder, the top surface and the bottom surface of the drainage cover component are composed of a ring 22 concentric with the main shaft 11, a plurality of spokes 23 and a flange 21, and the top surface and the bottom surface are connected into a cylindrical cage-shaped structure through a column 24. A movable diaphragm 25 and a fixed diaphragm 26 are arranged in an arc-shaped rectangular plane formed by the column 24 and the spokes 23, and the diaphragms are used for forming a plurality of arc-shaped air channels so that air flows along the arc-shaped air channels. A movable diaphragm adjusting mechanism 27 is fixed on the upper surface of the top spoke and the lower middle section of the bottom spoke, and the control mechanism drives the movable diaphragm 25 to move along the arc direction of the spokes through a transmission mechanism such as a gear rack mechanism. The flange 21 on the top and bottom surfaces of the framework is fixedly connected with the top cover 13 and the bottom cover 14 of the wind wheel component, and the diameter of the flange hole on the bottom surface of the framework is larger than the maximum diameter of the impeller 12. So that the wind wheel assembly 1 penetrates upwards from the lower part of the draft shield assembly 2.
In fig. 3, the support structure is composed of a plurality of columns 31, a pull rod 32 and a coupling flange 33, wherein part of the columns 31 can be shared with part of the columns 24 in the draft shield assembly 2, the pull rod 32 is designed to enhance the strength and stability of the structure, and the flange 33 is used for connecting a foundation or for stacking fan assemblies.
The vertical axis wind turbine comprises a hollow cylindrical cage-shaped structure, a membrane structure drainage plate group is arranged in the radial direction of the cylinder, the hollow part is used for accommodating a vertical axis wind turbine impeller structure, the vertical axis wind turbine impeller structure is fixed on the cylindrical cage-shaped structure, and a plurality of support columns can be installed on the periphery of the cage-shaped cylindrical structure to provide supporting force and torque resistance with enough strength for the whole structure.
The diaphragm structure flow guide plate group radiates from the inner circumference to the outer circumference in a curve, and the diaphragm is inwards approximately tangent to the central circle of the impeller and outwards approximately tangent to the radius line of the outer circle. A horn-shaped bent channel is formed between every two membrane structure drainage plates to guide airflow to tangentially flow to the fan impeller blades.
In order to obtain the best wind energy utilization rate, the circumference of the drainage plate of the membrane structure is equally divided into more than or equal to 8.
The natural wind is blocked by the membrane structure drainage plate and moves forward along the wind channel formed between the two membrane plates, the flow direction, the speed and the pressure of the wind are changed because the wind channel contracts in a horn shape from outside to inside, the enhanced wind blows to the blades of the wind wheel, the blades are driven to rotate to do work, and then the wind channel on the back expands to the leeward side to flow out.
Because the wind channel is arranged along the cylinder ring, no matter which direction the natural wind flows in, after the influence of the wind channel, the air flow forms an annular rotational flow in the middle of the drainage structure, and the annular rotational flow blows to the blades along the tangential direction of the inner circumference in general, namely, the wind turbine is always subjected to positive work, so that the wind loss is basically eliminated. The wind speed through the wind channel is enhanced, and for the fan impeller, the impeller shape of both a resistance type impeller and a lift type impeller can obtain higher rotating speed or rotating moment because of obtaining better wind speed conditions.

The cage-shaped structure has enough strength to resist the influence of severe natural environment, and is convenient for leading out a plurality of supporting columns to provide multi-point support, and the whole structure can obtain good stress condition without guy cables to keep the structural stability under the maximum wind power.
The membrane structure drainage structure is simple, the construction cost is low, if the outer circle of the drainage structure is large enough, a larger windward area can be obtained, and the moving part of the wind impeller does not need to be made large, so that a smaller wind impeller can be used for obtaining larger wind power, the torque of the wind impeller can be enhanced, the output power of the vertical axis wind turbine can be amplified, and a brand new thought is provided for constructing a large vertical axis wind turbine. The shape and size of the annular air duct can be optimized in real time by the aid of the movable diaphragm structure, so that the wind turbine can obtain a good power generation effect under various weather working conditions.
For better drainage and aesthetic considerations as well as preventing natural disasters such as rain, snow, dust, hail, etc., membrane structures are used at the top and bottom of the drainage hood for shielding.
Because the whole wind driven generator is not provided with high-speed moving parts, the damage to birds can be greatly reduced, and the environment friendliness is improved.
