Description

Turbine Vertical Shaft Wind Turbine

technical field

The invention belongs to the field of wind energy utilization, and relates to components such as a wind turbine, a wind collector, an impeller and the like in a vertical shaft wind power generator.

Background technique

Wind turbines are key equipment for wind power generation. At present, wind turbines include horizontal-axis wind turbines and vertical-axis wind turbines. Horizontal-axis wind turbines are used in both large-scale wind turbines and small-scale wind turbines. In the application process of horizontal-axis wind turbines, there are tower loads and balance. Poor performance, need for wind mechanism and other deficiencies. The vertical axis wind turbine generally does not need a wind-facing mechanism, and the generator can be installed on the ground to reduce the load on the tower. The cost is low and it is easy to maintain and maintain. Therefore, the vertical axis wind turbine has attracted widespread attention in recent years. Vertical axis wind turbines are divided into two types: drag type and lift type. For the resistance type vertical axis wind turbine, there is often a problem that half of the wind turbine is the power zone and the other half is the resistance zone during the working process. Therefore, in order to improve the wind energy utilization efficiency of vertical axis wind turbines, shielded flat-blade wind turbines, flat-blade swing wind turbines and S-shaped impeller wind turbines have been proposed, but the above-mentioned wind turbines may only use half of the impeller of the wind turbine. Therefore, it is necessary to develop a new type of vertical axis wind turbine.

Contents of the invention

The technical problem to be solved by the present invention is to provide a turbine-type vertical-axis wind turbine with good wind gathering performance, high wind energy utilization coefficient and low start-up wind speed.

Technical scheme of the present invention is as follows:

The turbine type vertical shaft wind power machine of the present invention is mainly composed of the wind collector bottom plate, the wind collector top plate, the left wind collector plate, the right wind collector plate, the volute, the upper blade hoop, the lower blade hoop, the blade, the inner cylinder of the blade, the shaft, Air concentrator bearing, impeller bearing, left wind concentrator empennage, right air concentrator deflector, right air inlet, air concentrator air outlet, guide rod, guide rod bracket, vertical guide fin and transverse guide fin. The upper hoop of the blade, the lower hoop of the blade and the blade constitute the impeller of the present invention, and the shaft of the impeller is installed vertically on the ground to form a vertical axis wind turbine; the bottom plate of the wind collector, the top plate of the wind collector, the left wind collector, the right wind collector and The volute constitutes the wind collecting device of the present invention; the volute, the left wind collecting plate empennage and the right wind collecting plate deflector constitute the wind guiding device of the present invention. Guide bar, vertical guide empennage and transverse guide empennage constitute wind-facing mechanism of the present invention.

The left airflow in the turbine-type vertical-axis wind power machine of the present invention enters the impeller along the left wind gathering plate, drives the impeller to rotate, and flows out from the air outlet of the wind gathering device.

The right airflow in the turbine type vertical axis wind machine of the present invention enters the right air inlet along the right air inlet constituted by the right air collecting plate and the volute, and then enters the impeller, drives the impeller to rotate, and flows out from the air outlet of the air collecting device.

The impeller in the turbine type vertical axis wind machine of the present invention drives the shaft to rotate under the action of wind force, and drives the wind generator to rotate to generate electricity; The wind collector automatically captures the wind direction under the action of the guide rod.

The impeller in the turbine-type vertical shaft wind turbine of the present invention can be made of metal; the wind gathering device can be made of metal, glass fiber reinforced plastic or plexiglass; the guide rod, vertical guiding tail and horizontal guiding tail can be made of metal or glass fiber reinforced plastic.

The effects and benefits of the present invention are that the left wind gathering plate of the turbine type vertical axis wind power machine of the present invention has the effect of gathering the left airflow, so that the airflow directly enters the impeller along the left wind gathering plate and pushes the impeller to rotate. The inlet width is relatively large and much larger than the impeller channel, so it is beneficial to increase the airflow velocity in the impeller and improve the moment of inertia of the impeller, which in turn is beneficial to reduce the starting wind speed of the wind turbine; the volute of the turbine vertical axis wind turbine of the present invention has a shielding The air flow directly acts on the impeller and forms resistance to the rotation of the impeller. On the other hand, the volute and the right air concentrator form the right air inlet channel. The air flows through this channel and enters the right The side air inlet enters the impeller, and together with the left airflow, the impeller rotates, thereby further increasing the moment of inertia of the impeller and reducing the starting wind speed of the impeller. The guide bar, the vertical guide fin and the lateral guide tail of the turbine type vertical axis wind power machine of the present invention constitute the wind-facing mechanism of the wind power machine, which has the effect of automatically facing the wind; The shape is conducive to increasing the contact area between the impeller and the airflow, and improving the efficiency of wind energy utilization; the diameter of the lower hoop of the blade is smaller than that of the upper hoop of the blade, and the lower part of the blade adopts an open arc design, which is conducive to utilizing the vortex airflow from bottom to top wind energy; the top plate of the wind gatherer of the turbine type vertical axis wind turbine of the present invention is beneficial to improve the wind gather performance.
