Problems solved by technology
[0004] As the power of wind turbines increases, on mechanical wind turbines, the volume and weight of the gearbox and the generator become larger and larger, which brings great difficulties to manufacture, installation and maintenance; As the power of wind turbines increases, the hydraulic pump needs to provide a large flow of hydraulic oil, but the existing hydraulic pumps cannot meet the demand; therefore, the production of high-power wind turbines is severely restricted

The invention discloses a hydraulic power mechanism. The hydraulic power mechanism comprises a rotary shaft, a support and at least one oil supply unit. The rotary shaft is rotationally arranged on the support. Each oil supply unit comprises an eccentric wheel, an eccentric outer ring, a plurality of first control valves, a plurality of telescopic oil cylinders, a guide cylinder and a guide rod, wherein the eccentric wheel is fixed to the rotary shaft, and the eccentric outer ring is rotationally arranged on the eccentric wheel in a sleeving mode; one end of each telescopic oil cylinder is hinged to the support, and the other end of each telescopic oil cylinder is hinged to the eccentric outer ring; the guide cylinder is fixed to the support, one end of the guide rod is hinged to the eccentric wheel, the other end of the guide rod is in sliding connection with the guide cylinder, and the guide rod can slide in the radial direction along the rotary shaft relative to the guide cylinder; the first control valves are connected with the telescopic oil cylinders and used for controlling oil suction and oil discharge of the telescopic oil cylinders. By means of the hydraulic power mechanism, large flow of hydraulic oil can be provided, and accordingly requirements of a wind power generator are met. On the basis, the invention further discloses a hydraulic wind power generator provided with the hydraulic power mechanism.
Description
technical field [0001] The invention relates to wind power generation technology, in particular to a hydraulic power mechanism and a hydraulic wind power generator. Background technique [0002] Wind energy is an important renewable and clean energy. Wind energy has broad development prospects in development value and commercial promotion. The technical solutions of using wind energy to generate electricity have been continuously researched and developed in various countries. As the core equipment of wind power generation, the quality of wind power generator largely determines the economic benefits of wind power generation technology. [0003] Generally, a wind turbine consists of three important parts: a tower, a nacelle (also known as a tower head) and blades. The nacelle is set on the top of the tower, and the blades are connected to the nacelle through a transmission shaft; type and hydraulic type. On a mechanical wind turbine, the nacelle is equipped with a gearbox, a...
