Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The present invention takes a 100kW wind power generation transmission device as an example.

[0023] The energy conversion process of the wind power generation transmission device of the present invention is as follows: figure 1 As shown, after the wind wheel of the wind turbine converts wind energy into mechanical energy, the hydraulic pump of the wind power transmission device of the present invention converts mechanical energy into hydraulic energy; the hydraulic energy is transmitted to the hydraulic motor through the hydraulic components of the transmission device, and then the hydraulic The motor converts hydraulic energy into mechanical energy, which drives the generator to generate electricity. In this process, long-distance energy transmission is realized, and the low output speed of the wind turbine rotor is increased to the ...

Abstract

The invention relates to a wind power generation actuating device which adopts the hydraulic drive mode to replace the traditional gear step-up drive and can realize long-distance mechanical energy transmission of wind power generation so as to realize the purposes of putting a generator on the ground, lightening wind machine high-altitude quality and lowering installation and maintenance difficulty and cost. The wind power generation actuating device of the invention comprises a power part (volume adjustable hydraulic pump), an actuating part (hydraulic motor) and a hydraulic transmission and control part, wherein the hydraulic transmission and control part comprises a volume throttling flow control circuit and ensures the rotation speed of the hydraulic motor. In addition, the hydraulic transmission part also comprises an energy accumulator, a cooling part, an oil filter and a one-way valve, wherein the energy accumulator is used for providing assistant power, and the cooling part is used for cooling hydraulic oil when temperature is too high.

Description

technical field [0001] The invention relates to a transmission mode and device, in particular to an energy transmission mode and transmission device applied to wind power generation. Background technique [0002] Wind power generation uses wind energy to generate electricity, and wind turbines are machines that convert wind energy into electrical energy. The blades of the wind rotor on the wind turbine generate aerodynamic force under the action of the airflow to rotate the wind rotor and convert wind energy into mechanical energy. As far as the horizontal axis wind turbine meter is concerned: the transmission mechanism is responsible for the transmission of energy in wind power generation, changing the very low speed of the wind rotor (usually 27 rpm for a 600-kilowatt fan) into a very high speed of the generator (usually at 1500 rpm). At the same time, it also makes the generator easy to control and realizes stable frequency and voltage output. Its performance directly ...
