Background technique

At present, the general methods of obtaining electricity generally include thermal power, hydraulic power, wind power and nuclear power generation methods. Among them, thermal power and nuclear power generation methods are prone to lack of environmental pollution, and are often obstructed and opposed by people related to environmental protection and ecology. Hydroelectric power generation is limited by the need to build dams, and it needs ample water. If it encounters a dry season, it will not be able to generate electricity. However, wind power generation has the characteristics of clean, zero pollution and self-production, and can be used continuously. Therefore, at present All countries in the world are actively promoting wind power generation technology, and in the United States, Denmark and other countries rich in wind power resources, wind power generation technology has become increasingly mature, and the application level has reached a very large scale, resulting in an explosive increase in the number of global wind power generation installations in recent years. Growing, from Europe, the United States, to Japan, India, are actively building wind power plants, which shows that wind power generation is the trend of the times.

The above-mentioned wind power generation device, please refer to shown in Figure 4, this wind power generation device comprises fan 3 and generator 4, fan 3 wherein is provided with fan blade 31, and is provided with pivot 32 at its axle center, and generator 4 is connected with the pivot 32 of the fan 3, so that the pivot 32 of the fan 3 drives the generator 4 to generate electricity.

However, the above-mentioned wind power generation device has the following deficiencies in actual use:

1. The above-mentioned wind power generation device must have a pivot on the axis of the fan, so that the pivot of the fan can be connected to the generator, so that the fan can drive the generator to generate electricity, which will increase the manufacturing cost and increase the assembly cost. Annoyance and inconvenience.

2. When the above-mentioned wind power generation device generates electricity, the fan rotates the pivot, and then the pivot drives the generator to generate electricity. This will cause the loss of the pivot and the friction loss of the wind, reducing the reliability of the generator. Simultaneously increase the cost of maintenance again.

Utility model content

The purpose of this utility model is to provide a structure of an outward-rotating direct-drive wind-driven generator. The structure of the outward-rotating direct-drive wind-driven generator is to directly drive the generator body to rotate by connecting the bracket and the blades to the generator body, without Any transmission element needs to be installed between the bracket and the generator body to improve the reliability of the generator body's power generation and save costs.

The purpose of this utility model is achieved in this way, an external rotation type direct drive wind power generator structure, the structure has a generator body, the axis hole of the generator body is pivotally connected to the base column, and the generator body is fixedly equipped with fan blades .

The base column is provided with a bearing, and the bearing is pivoted to the axis hole of the generator body.

The main body of the generator is fixedly connected with a plurality of brackets, and the fan blades are fixed on each bracket.

The generator body is provided with a screw hole, and the screw hole is pierced with a screw fixing element, and the screw fixing element locks the bracket.

The fan blade is formed with an arc-shaped head end and a sheet-shaped tail end.

From the above, the utility model has the following advantages compared with the existing structure:

1. The generator body of the utility model is an externally rotating direct-drive wind power generator, which is convenient for the operator to fix the bracket and the fan blades on the outside of the generator body, and each fan blade can directly drive the generator body when it rotates. Rotate to reduce wind friction loss.

2. Since the fan blades of the present invention directly drive the generator body to rotate, there is no need to install any transmission elements between the bracket and the generator body, which can reduce the manufacturing cost.

3. The utility model does not require transmission elements between the bracket and the generator body, which can save the wear and tear of the transmission elements, so as to improve the reliability of power generation of the generator body and save maintenance costs.
