Description

A New Vertical Axis Wind Turbine

Technical field

The utility model relates to a novel vertical-axis wind power machine, in particular to a novel vertical-axis wind power machine which can be installed in residential areas and utilize wind energy.

Background technique

At present, the torque in the market is unstable and there is "negative drag" on the convex surface of the blade, this "negative drag" produces a negative torque and reduces the output power. There are two types of vertical axis wind turbines: lift and drag. The lift-type wind turbine with two blades has low starting torque and high efficiency, and the drag-type wind turbine has high starting torque and low efficiency. Now it is more popular to design hybrid wind turbines, which can use lift and drag or use low-cost methods to increase the starting torque and efficiency separately. Reasons why wind turbines are unpopular in residential areas: 1. At low wind speeds, due to the low starting torque of two-blade wind turbines, the efficiency of the lift-type wind turbines is particularly low. 2. The resistance type wind turbine can start automatically at low wind speed, but the efficiency is not high.

Utility model content

In order to reduce the consumption of non-renewable energy, wind turbines can also be installed in economically developed areas. Wind turbines can be installed in the city, and if a wind turbine is installed on the roof of each building, it can significantly reduce the transmission of electricity from remote power stations. The utility model provides a novel vertical axis wind turbine. The first scheme of the device includes a rotor; a half wind shield, a stator, a flange 1, a thrust ball bearing, a flange nut, a flange 2, a flange nut 2, Tail. The rotor is connected to flange 1 and flange 2 through nuts, the stator is connected to the stator through flange nut 1, and the flange 1 is connected to the stator with a thrust ball bearing. A thrust ball bearing is installed on the flange 2, and the flange nut 2 is connected with the half wind shield by bolts. The second scheme is to replace the half-wind shield with a symmetrical windshield. The four leaves of the symmetrical windshield are respectively connected to the stator through bolts and do not rotate with the rotation of the rotor. The third option is the case of only the rotor.

Preferably, when the wind blows, due to the special structure of the half-wind shield and the effect of wind force, the air inlet of the half-wind shield automatically faces the wind direction, and the wind blows from the air inlet to the six leaves of the rotor, and the half-wind shield The negative torque generated by the wind blowing to the convex surface of the leaf fan is greatly reduced.

Preferably, when there is wind blowing, the wind blows from the air inlet of the symmetrical windshield to the six leaves of the rotor, and the symmetrical windshield greatly reduces the negative torque generated by the wind blowing to the convex surface of the leaf.

Preferably, according to the size of the wind force in various places, three structures can be selected: the rotor alone, the rotor plus a half wind shield, and the rotor plus a symmetrical windshield.

Preferably, the rotor rotates under the blowing of the wind and drives the load to transform the wind energy into other forms of energy for people to use.

The beneficial effect of the utility model is that the special structure of the semi-wind shield and the symmetrical windshield reduces the negative torque generated by the wind blowing to the convex surface of the leaf fan, and greatly improves the efficiency of utilizing wind energy. Moreover, the utility model has the advantages of simple structure, low manufacturing cost, convenient use and durability.

Detailed ways

The first scheme of the device includes a rotor; a half windshield, a stator, a flange 1, a thrust ball bearing, a flange nut, a flange 2, a flange nut 2, and an empennage. The rotor is connected to flange 1 and flange 2 through nuts, the stator is connected to the stator through flange nut 1, and the flange 1 is connected to the stator with a thrust ball bearing. A thrust ball bearing is installed on the flange 2, and the flange nut 2 is connected with the half wind shield by bolts. When the wind blows, due to the special structure of the half-wind shield and the effect of wind force, the air inlet of the half-wind shield automatically faces the wind direction, and the wind blows from the air inlet to the six leaves of the rotor, and the half-wind shield greatly reduces the Due to the negative torque generated by the wind blowing to the convex surface of the fan, and there is a large space in the middle of the rotor, a large amount of wind coming in from the inlet of the half wind shield blows to the concave surface of the fan opposite the air inlet, recycling wind energy and speeding up the rotor speed, thereby improving efficiency. The rotor rotates under the blowing of the wind, and drives the load to convert the wind energy into other forms of energy for people to use. The second scheme is to replace the half-wind shield with a symmetrical windshield. The four leaves of the symmetrical windshield are respectively connected to the stator through bolts, and do not rotate with the rotation of the rotor. When the wind blows, the wind blows from the air inlet to the six leaves of the rotor, and the symmetrical windshield greatly reduces the negative torque caused by the wind blowing to the convex surface of the leaves, and there is a large space in the middle of the rotor. Therefore, a large amount of wind coming in from the inlet of the symmetrical windshield is blown to the concave surface of the leaf fan opposite the air inlet, and the wind energy is recycled to accelerate the rotating speed of the rotor, thereby improving the efficiency. The rotor rotates under the blowing of the wind, and drives the load to convert the wind energy into other forms of energy for people to use. The third option is the case of only the rotor. The utility model not only greatly improves the efficiency of utilizing wind energy. Moreover, the structure is simple, the manufacturing cost is low, the use is convenient and durable.

The specific implementations described above are preferred implementations of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to this specific implementation. , The equivalent changes made by the structure all include the protection scope of the present utility model.
