Description

technical field [0001] The present invention relates to a wind energy generating equipment, in particular to a ground follower mechanism of a floating wind power generation equipment using high air flow to generate power, and a ground drive system with the ground follower mechanism. Background technique [0002] Wind power generation equipment is a structure that converts the energy carried by the airflow into mechanical energy, and then converts the mechanical energy into electrical energy through a generator. At present, the common wind power generation equipment is the wind power generation equipment installed on the ground. This kind of wind power generation equipment can only receive and utilize the wind energy on the surface, and because the wind speed near the ground surface is low and the energy is small, if you want to increase the power of wind power generation, It is only possible to use large-sized fan blades to increase the wind-receiving area, which also brings...

Problems solved by technology

However, these power generating devices also have some common shortcomings: 1. Because the wind energy receiving device and the generating mechanism are all floating in the air, the structure of the wind power generating device is complicated and the weight is heavy, which restricts the further improvement of its power; 2. Power generating devices with relatively large volume and weight are installed in the air. Once they crash, they will pose a threat to the safety of the ground, and the safety is poor.

[0006] 1. All kites float downstream with the wind, and the pulling force is huge, resulting in great shear stress at the bearings and great friction

It is easy to cause equipment damage and consume a lot of energy due to friction

[0007] 2. On the one hand, the position of the power input shaft of this kind of power generation equipment is fixed, and the kite continuously drives the power input shaft to rotate under the action of the wind; , so alternating shear stress will be generated on the power input shaft, which will affect the fatigue life of the power input shaft. When the wind is strong, the huge shear stress on the power input bearing may also Destroying the lubrication of the input shaft will lead to increased wear of the components, reducing the service life of the wind power generation equipment, and even causing fatigue damage to the moving parts, leading to early scrapping of the equipment

[0008] 3. As the kite is retracted and released, pulsating shocks appear continuously, resulting in pulsating electricity, which increases the investment in the power transmission system and the complexity of the working process
