Compared with the existing wind power generators, the double impellers are driven at the same time, which improves the utilization rate of wind energy and saves wind power generation equipment, especially the generator system. The overall center of gravity is moved down to improve its stability. , so that the impeller automatically faces the wind direction, improving power generation efficiency.

Description

Double impeller wind turbine

technical field

The utility model relates to a wind power generator, in particular to a double impeller wind power generator.

Background technique

Due to the declining reserves of non-renewable resources such as petroleum and the increasingly serious environmental pollution, the requirement for improving the efficiency of clean energy development is becoming more and more urgent.

At present, there are many methods in the field of clean energy development, and wind power generation is one of them, and its development space is very large. But, the cost of wind power generation system is expensive now, and each generator is only equipped with a big impeller, not only waste equipment but also the utilization rate of wind energy is quite low, and power generation efficiency is very poor.

Utility model content

The utility model aims at solving the above problems, and provides a double impeller wind power generator. To a certain extent, it overcomes the problems of low power generation efficiency of traditional wind power generators and waste of power generation equipment. The technical scheme adopted is as follows:

Double-blade wind turbines, including blades, power shafts, blade mounting bearings, power bevel gears, power driven gears, power transmission shaft mounting bearings, rotating support mounting bearings, wind rudders, rotating supports, power transmission shafts, fixed supports seat and a lower power generation system, the power driven gear is fixedly connected to one end of the upper part of the power transmission shaft, the rotating support is installed on the upper part of the fixed support using a rotating support mounting bearing, and the power transmission shaft passes through the power transmission shaft The installation bearing is installed on the rotating support and the fixed support. The lower power generation system is located at the lower part of the fixed support and is connected with the power transmission shaft. The power driven gear and the power transmission shaft rotate to drive the lower power generation system to generate electricity. and transmit and store electricity.

The blades are respectively mounted on both ends of the power shaft and located on both sides of the rotating support. The power shaft connects the blades to the upper part of the rotating support through blade mounting bearings. The power bevel gear is installed on the power shaft and is connected with the power The driven gear forms a gear fit, the blade rotation drives the power shaft and the power bevel gear to rotate, and the power bevel gear cooperates with the power driven gear to drive the power driven gear and the power transmission shaft to rotate.

The wind vane is fixedly connected to the lower side of the rotating support, and the wind blows the wind direction rudder to rotate, and the wind direction rudder drives the rotating support to rotate, so that the rotating support drives the blades to turn to the direction of the wind, so that the front and rear can be blown with the maximum wind force. The blades spin.

The utility model has the following advantages: the double impellers are driven at the same time, which improves the utilization rate of wind energy, saves wind power generation equipment, especially the generator system, moves the overall center of gravity down, improves its stability, and adds a wind vane to make the impellers automatically Wind direction, improve power generation efficiency.
