Description

Rotary vane type vertical axis wind wheel generator

Technical Field

The invention belongs to the technical field of wind driven generators, and particularly relates to a rotating vane type vertical axis wind driven generator.

Background

Wind power belongs to clean energy and is widely applied to areas with the advantage of wind power resources. The wind power equipment is structurally divided into a horizontal axis wind power generator and a vertical axis wind power generator according to the angle relation between a rotating shaft of a wind wheel and the wind direction. At present, a horizontal axis wind driven generator is relatively popular, the power generation capacity also reaches a higher level, and the proportion of new energy and clean energy in the whole energy supply is greatly improved. But because the mass is large, for example, the height of a tower exceeds 200 meters, the diameter of an impeller exceeds 180 meters, and the manufacturing, transportation and installation have great difficulty; greater uncertainty is brought to the stability and reliability of operation; because the volume is large, the requirements on the environment, space, traffic conditions and installation equipment of an installation site are high, and the construction cost is high; but also the risk of relatively defending against natural disasters. Therefore, vertical axis wind turbines are also receiving increasing attention in relation to the above-mentioned problems with horizontal axis wind turbines.

The vertical axis wind turbine does not need to face the wind when the wind direction changes, and is a great advantage in this respect compared with a horizontal axis wind turbine, which not only simplifies the structural design, but also reduces the gyroscopic force of the wind wheel when facing the wind. The vertical axis wind driven generator driven by resistance to rotate has several types, wherein a wind wheel made of a flat plate and a wind cup is used as a pure resistance device; the S-windmill has partial lift, but is mainly a drag device. These devices have a large starting torque, but the tip ratio is low, providing a lower power output for a given size, weight and cost of the rotor.

The chinese patent "sail wing type vertical axis wind turbine" with application number 201920983777.2 discloses a sail wing type vertical axis wind turbine, which comprises a rotating shaft, a generator arranged at one end of the rotating shaft, and a sail unit arranged in the circumferential direction of the rotating shaft; the sail unit is provided with a plurality of vertical and rotatable blades at intervals, and the resistance generated by air flowing through the blades is used for driving the generator to generate electricity. Due to the defects of the structural design, the blade rotation resistance is large, the stability and the strength of the main structure are poor, the structural failure rate of the rotation shaft and the generator shaft is high, and meanwhile, the maintenance difficulty is increased.

The utility model discloses a rotor blade formula vertical axis wind turbine generator's theory of operation as follows:

the engine is in a static state when no wind exists; after wind starts, the turning angles of the small fan blades 3 at different positions are different, so that the maximum area of the blade surface of the wind wheel blade 2 can receive wind power when the wind wheel blade does work, the wind area is reduced to almost zero when the wind resistance is met, and when the wind wheel blade 2 is positioned in A, B areas, the air assistance is greatly different due to the fact that the areas in the windward direction are extremely asymmetric, and therefore the wind efficiency of the wind driven generator is greatly improved.

Under the action of wind force, because the small wind blades 3 on the 4-face wind wheel blades 2 are subjected to different wind forces in different areas, different turning angles are formed, so that the wind receiving areas of the 4-face wind wheel blades 2 are different, the larger the wind receiving surface is, the larger the wind receiving thrust is, and the smaller the wind receiving thrust is otherwise; because the areas of the wind wheel blades 2 in the windward direction are extremely asymmetric, the air assistance is caused to generate a moment rotating around the vertical shaft 1 of the wind wheel, so that the wind wheel rotates; as shown in fig. 1 and 2, when any one surface of a wind wheel blade 2 arranged in a regular cross shape is positioned in a region a (a work region of the wind wheel blade under the action of wind force), a small wind wheel blade 3 on the wind wheel blade sags due to gravity (the area and the mass of the lower part of a rotating shaft 4 of the small wind wheel blade are larger than those of the upper part of the rotating shaft), a complete large wind receiving plane is formed under the boosting of wind force (the limiting pile 5 arranged on a wind wheel frame 8 prevents the wind wheel blade from turning backwards), and the wind wheel blade 2 is pushed to turn to a region B (a wind resistance region of the wind; when the wind wheel blade 2 rotates to the area B, because the direction of the wind power borne by the wind wheel blade is opposite to the area A, the area below the small wind wheel blade rotating shaft 4 is larger than the upper part, and the wind power borne by the wind wheel blade is also larger, after the wind power overcomes the action of drooping gravity, the small wind wheel blade 3 turns backwards around the small wind wheel blade rotating shaft 4 to form an included angle of nearly 90 degrees with the plane of the wind wheel blade 2, at the moment, the wind wheel blade 2 forms a hollow frame, the wind bearing area reaches the minimum value, and the wind wheel blade 2 is pushed by the area A to turn to; therefore, the four-side wind wheel blades 2 respectively generate thrust in the area A, unload resistance in the area B, circularly reciprocate to drive the wind wheels to rotate, transmit power to the generator 12 through the transmission belt 11 to generate power, and output power through the transformer 13.

Compared with the existing resistance type wind driven generator, the rotary vane type vertical axis wind wheel generator of the utility model has great kinetic energy difference of A, B areas under the same wind area, and the wind efficiency utilization can reach the maximum; therefore, the rotating vane type vertical axis wind turbine generator has relatively high wind energy conversion rate and higher power output for given weight and cost of the wind turbine; even can be compared with the lift type vertical axis wind driven generator under the same wind power condition.
