Background

Wind power generation is one of clean energy sources, and is widely applied to the environment with more wind resources at present. The wind power generation equipment is structurally divided into: the wind power generation system comprises a horizontal axis wind power generation system with a rotating shaft of a wind wheel parallel to the wind direction, and a vertical axis wind power generator with a rotating shaft of a wind wheel vertical to the ground or the direction of airflow. Horizontal axis wind power generation has been developed to 15 megawatts with tower heights in excess of 200 meters and impeller diameters in excess of 180 meters, which presents significant challenges to the design, installation, maintenance, and reliability of large wind power generation. On land, the increase of the power of the onshore wind turbine is limited due to the difficulty of transportation caused by the overlong blades; for an offshore wind turbine, under extreme weather conditions such as typhoon, irreversible damage can be caused to a high-rise wind tower and blades.

Because the vertical axis wind turbine does not need to face the wind when the wind direction changes, the vertical axis wind turbine is a great advantage in this respect compared with a horizontal axis wind turbine system, 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 turbine is divided into a resistance type and a lift type, the resistance type has low utilization rate of wind energy, and cannot be used for large-scale wind power generation. One reason that the conventional vertical axis high-power wind power generation system is not as popular as a horizontal axis fan is that the larger the power is, the larger the blade is, and the larger the weight of the blade is, the larger the cantilever beam structure is difficult to be. The efficiency of the existing vertical axis wind turbine is relatively low.

The traditional large megawatt wind power generation system mainly adopts a horizontal shaft type as a main model, and because of the requirement of thrust, the fan blade of the system is required to be very large and very long, generally about 30-50 meters, the shaft center of a vertical shaft generator is the circle center taking the length of the fan blade as the radius, and the safe remaining height of the blade tip from the ground is added, and the tower base of the generator is built to be 50-70 meters high, so the height of the whole equipment is basically more than 100 meters; due to the rotation of the fan blades, great potential safety hazards are caused to birds, aircrafts and the like in an airspace, and great threat is caused to the ecological balance of the environment; in addition, due to the structural form, once any part of the system fails, the whole equipment stops running, so that the power generation loss is caused, the maintenance is very difficult, and the running and maintenance cost is high.

After the fan main shaft of the traditional wind driven generator is connected with the fan blades, the positions and the number of the fan blades which cannot be moved are fixed, the fan blades can only be customized one by one, the number and the positions of the fan blades are difficult to adjust conveniently according to the actual conditions of a wind field and the needs, and the fan blades cannot be randomly arranged on the fan main shaft of the same specification, so that the modular processing of the fan main shaft is difficult to realize, the cost is high, and the production efficiency is low.

The invention breaks through the inherent thinking of the prior art in the field, overcomes the defects and shortcomings of the prior art, the fan blade assembly rotates on a horizontal plane, and does not need a large-size fan blade, so the overall height can be reduced, the height of the fan blade assembly has a constant value, the influence on birds and aircrafts in an airspace is greatly reduced, and the potential safety hazard is removed; the fan blade components are segmented in a layered mode, namely a plurality of fan blade components are connected in parallel, so that the wind receiving surface of each fan blade component is increased by multiple times on the land occupying unit area, the received wind power is greatly enhanced, the rotating speed and the generating capacity of the generator are improved by multiple times, the generating efficiency of the vertical axis wind driven generator is greatly improved, and the land is saved; the fan blade components are installed in a layered and segmented mode, the size and the number of the segments can be flexibly selected according to the thrust required by the total power of the generator, and the installation angles of the fan blade components on the layers can be adjusted in a coordinated mode when the fan blade components are installed integrally, so that the thrust of the fan blade components to the main shaft is more uniform, and the rotation of the main shaft of the fan blade is smoother and smoother; because of the sectional structure, compared with the traditional integral fan blade, the manufacturing difficulty and the strength requirement are greatly reduced, the manufacturing cost is greatly reduced, the machine does not stop when needing to be overhauled and replaced, and because the rotating speed is low and the machine operates on one section, one section is just like a room, the overhauling and replacing operation is high in safety; because each layer is an independent operation individual and can be connected, put into and disconnected at any time through the clutch, the generator can be reasonably scheduled according to the current wind power condition except that other equipment is not influenced when a certain equipment is overhauled, maintained and replaced, the generator is put into more wind power when the wind power is large, and the generator is put into less wind power when the wind power is small, so that the defects of 'damage and honor' of a traditional single generator are avoided, the functions of the equipment are greatly exerted, and the efficiency, benefit and benefit of the system are greatly improved; therefore, the vertical axis wind driven generator has high generating efficiency and is a wind and light integrated and complementary vertical axis wind driven generator.

In the invention, the electric power generated by wind and light can be uniformly sent out and stored after being converged, the fan tower can be independently used as an independent system, or a plurality of fan towers form an array to be used as a wind and light complementary power station, the generated electric power can be used as an independent micro-grid or can be merged into a large power grid, and the generated electric power can be used for carrying out science popularization education and environmental protection education on people, thereby being a new energy project which is beneficial to the country and the people and benefits the offspring.

The invention can be designed into various modeling towers according to the needs, adopts a new concept, combines wind and light power generation, energy storage and landscape, enables the landscape to become a part of new energy, is beautiful, is combined with art in design, has novel design, exquisite modeling, superior materials and exquisite manufacturing process, can be used as a part of sightseeing landscape, can generate clean electric power, makes maximum use of limited resources, and is particularly suitable for the global energy-saving and environment-friendly large environment. The project is designed independently, and through trial production and actual trial on the project site, the trial effect is tested in various aspects such as wind resistance, lodging resistance, wind and light power generation capacity, efficiency, electric energy quality and the like, the performance of each aspect meets the design requirements, the effect is very obvious, and perfect success is achieved.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.

The invention can be widely applied to the field of wind power generation.
