Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a vertical-axis horizontal wind wheel device. Background Art

[0002] Wind is a new energy source with great potential. The wind power resources available for power generation on Earth are about 10 billion kilowatts, which is almost 10 times the current hydroelectric power generation in the world. As energy is increasingly scarce in the world, both at home and abroad, great attention is paid to the use of wind power for power generation.

[0003] The existing Chinese utility model patent with publication number CN216111101U and titled "A multi-level symmetrical vertical axis wind turbine independent impeller device" includes a generator, the rotating shaft of the generator is fixedly connected to a turntable, the turntable is fixedly connected to a cylindrical cage, and the outer circumference of the cylindrical cage is provided with several layers of wind blades, and the wind blades of each layer are arranged in a circle. However, when the device is used in cold areas, the ice attached to the upper wind blades will easily damage the lower wind blades after falling, affecting the power generation efficiency, and the diagonal braces inside the cylindrical cage are relatively dense, which is extremely inconvenient to hoist to the top of the tower for installation. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the vertical axis horizontal wind wheel device of the utility model is:

[0006] A vertical axis horizontal wind wheel device comprises a tower, on which a main generator is arranged, the rotating shaft of the main generator is fixedly connected to a turntable at the top of the tower, the top surface of the turntable is provided with a plurality of cantilever beams arranged in a circle, one side of the cantilever beam is fixedly connected to the turntable, and the other side is provided with main wind blades and auxiliary wind blades in sequence from the outside to the inside.

[0007] Preferably, a column is provided in the middle of the turntable, and an inclined rope is provided between the column and the cantilever beam.

[0008] Preferably, the length of the cantilever beam is 20-60 meters.

[0009] Preferably, the main generator is located at the bottom of the tower.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The main wind blades and auxiliary wind blades are installed on the cantilever beam. The two are arranged horizontally, and there is no risk of being damaged by falling ice, thereby ensuring the power generation efficiency. The cantilever beam has a simpler structure and has sufficient operating space when hoisted to the top of the tower, which is convenient for installation. BRIEF DESCRIPTION OF THE DRAWINGS
