Technical field

The present invention relates to the field of wind power generation technology, and more particularly to providing a wind power generator capable of efficiently utilizing wind power generation, which can be widely applied to power a variety of mechanical equipment.

Background technique

In China, there are few mechanical equipments powered by wind energy, and some existing wind energy utilization equipments are generally large in size and have a single blade structure. Therefore, there are widespread deficiencies in low utilization of wind energy and poor air collection. The reason is that there is no better and more effective way to gather winds in order to increase the utilization of wind energy.

Summary of the invention

The object of the present invention is to provide a set of artificial wind, artificial cyclone, artificial wind tunnel, wind rudder, and adjacent wind tunnel rotating in different directions for action and belt. The blade with angled angle can significantly increase the wind speed of various technical combinations such as impeller speed.

The invention is realized as follows: It comprises an impeller, a blade, a shaft, a transmission device and a power generating device, and is characterized in that: at least two sets of impeller groups with impellers and blades are arranged on the shaft, and the outer side of the shaft and the impeller group are set. There is a tubular wind tunnel, which is connected to the shaft support through a shaft bracket, and a conical air hood is connected at the air inlet of one end of the tubular wind tunnel.

The blades in the adjacent impeller group may be blades with opposite inclination angles and opposite rotation directions as needed, that is, the blades in the adjacent impeller group rotate in opposite directions, and the blades in the spaced impeller group rotate. The direction is the same; it can also be a blade whose blade inclination angle is set in the same direction and the rotation direction is the same.

The air collecting hood is uniformly distributed with a venting opening, and one side of the air venting opening is further provided with a switch spring bracket capable of automatically adjusting the ventilation amount according to the wind force.

The transmission described above includes a pulley connected to the impeller disposed on the shaft, and a pulley connected to the power generating device with the transmission.

In order to avoid damage to the impeller group due to excessive wind force, a slider is provided on the outer edge of the blade.

Confirmation A rolling chute is disposed on the inner wall of the wind tunnel corresponding to the slider.

In order to make full use of the wind direction and the wind speed to maximize the use of wind energy, a spiral rib forming a cyclone guide is evenly distributed on the hood close to the cylindrical wind tunnel. With the wind of the cyclone guide, the blades in the selected impeller group are blades in which the blade inclination angles are set in the same direction and the rotation direction is the same.

When the impeller is rotated alone, the impeller and the pulley are fitted on the shaft.

A bearing is arranged between the impeller, the pulley and the shaft.

Blades in the impeller set are also provided with blade chamfers that increase the rotational speed of the impeller. The angle of the blade chamfer is in the range of 5-30 degrees.

The blades may have a blade chamfer on the left or right side of the blade due to different directions of rotation.

When the impeller is rotated by a shaft, a bearing of the seat and a shaft bracket are connected at both ends of the shaft, and the impeller and the pulley are fixedly connected to the shaft.

The invention has the advantages that: the wind collecting hood and the cyclone guiding channel have a strong air volume, and the wind tunnel has to be diffused through the wind tunnel to generate a wind tunnel effect. One-axis multi-impeller, the impeller can rotate in the same direction, and the two adjacent impellers have different directions of rotation in the wind direction of the blades, and the mutual rotation does not cause overlapping rotation. A variety of technical combinations, such as a gusset with a chamfer and self-protection on the blade, can increase the effectiveness of the wind. The invention has the characteristics of convenient use, obviously improving the efficiency of the wind energy and increasing the rotation speed of the impeller, and the clean and reproducible wind energy is an inexhaustible natural resource, so the invention has broad market prospect, economical and environmental protection. And social benefits are significant.
