Rotating speed adjusting type wind power generation rotating mechanism

Abstract

The invention discloses a rotating speed adjusting type wind power generation rotating mechanism, and relates to the technical field of power generation equipment. The mechanism comprises a gearbox and a rotating part, the rotating part comprises a shaft body, blades and flow deflectors, the multiple blades are annularly distributed on the circumferential side face of the shaft body, and the ends of the blades extend to form the flow deflectors. The outer side of the rotating part is sleeved with a first sleeve body, the first sleeve body is installed on the shaft body through a bearing, a second sleeve body is installed on the inner side of the first sleeve body in a sliding mode, the second sleeve body is connected to the outer side of the rotating part in a sleeving mode simultaneously, a cavity is formed between the first sleeve body and the second sleeve body, and a valve body is installed at an opening, communicated with the outside, of the cavity. An input shaft of the gearbox is connected with a shaft body of the rotating part through a coupler. The sliding blocks in the bearings move outwards under the action of centrifugal force, the gas pressure in the cavity formed between the first sleeve body and the second sleeve body is changed, therefore the second sleeve body is pushed to move upwards, and the rotating speed of the rotating part is controlled.

Description

technical field [0001] The invention belongs to the technical field of power generation equipment, and in particular relates to a speed-adjustable wind power generation rotating mechanism. Background technique [0002] With the development of social economy and the improvement of people's living standards, the demand for energy continues to grow, and the development and utilization of new energy and renewable energy is an inevitable trend. In the family of new energy and renewable energy, solar energy and wind energy are one of the most widely used clean energy sources. There have been many types of solar generators and wind energy generators. The most common wind energy generators are equipped with multiple huge The fan blades are driven by wind energy to rotate to generate electricity. However, due to the heavy weight of the fan blades, a certain level of wind power is required to drive the fan blades to rotate, and the requirements for wind power are relatively strict. M...
